Definitions
- the present invention concerns a lift system primarily comprising a vertical mast constructed of a number of inter-fitting sections and a lift car of cage or platform type that can be moved along the said constructed mast for the carriage of persons or goods.
- a lift car of cage or platform type that can be moved along the said constructed mast for the carriage of persons or goods.
- the aforesaid lift type can be used as a service lift in permanent installations, its particular range of uses is for erecting or renovating buildings, whereby the lift is constructed for temporary use.
- One essential advantage is hereby that the mast incorporated in the lift system can easily be adapted to the gradually increasing height of the building by extending it with new sections stacked and mounted on top of each other. The thus erected mast can be dismantled in a converse manner by disassembling the sections and transporting them down from the top of the mast by means of the lift car.
- the roof of the cage is normally used not just as a load bearing surface for the transport of mast sections to and from the top of the mast but also as a working platform for constructing the mast and for associated assembly work.
- a type of crane arranged on the lift car is normally used.
- the inter-fitting mast sections are fastened to each other by means of removable connectors arranged at the adjoining upper and lower ends of the sections.
- the said connectors usually comprise conventional screw joints.
- the floor structures of the building can serve as a working platform when fixing the one end of the stay element that is to be anchored to the building structure.
- the building structure is completely smooth, such as on a chimney stack or the like, all assembly and anchoring work must normally be carried out directly from the lift car. The distance between the lift car and the building structure in most cases is too great for this work to be carried out in a safe and ergonomically correct manner.
- the work of erecting and tearing down the said masts is among the heaviest and most risky tasks that can be performed.
- the object of the present invention is therefore to achieve a lift system of the type described in the introduction that is so constructed that the work carried out around the mast with regard to its erection and tearing down can be simplified and carried out in a manner that is safer for personnel.
- the invention is aimed at simplifying the erection and tearing down of mast sections as well as simplify the application and removal of the stay elements between the building structure and the mast.
- This object of the invention can be achieved with the present lift device being given the distinctive features and characteristics specified in claim 1. Further distinctive features and advantages of the lift system according to the invention are given in the dependent claims.
- fig. 1 shows a perspective view of a lift system according to the invention, whereby a service and assembly platform supported by the lift car is swung into a working position adjacent to the mast along which the lift car runs
- fig. 2 shows a perspective view corresponding to fig.
- fig. 3 shows a perspective view of the pivoting means of support used to carry the service and assembly platform and to which it is swung into a position of rest above an upper load bearing surface of the lift car
- fig. 4 shows a perspective view from above of the service and assembly platform in its swung-out position
- fig. 5 shows a side view partially in cross section of the service and assembly platform
- fig. 6 shows a view from above of the service and assembly platform swung-out in its normal working position
- FIG. 7 shows a perspective view of a lift system according to the invention in an alternative embodiment whereby the service and assembly platform supported by the lift car is arranged at an essentially elevated level relative to the upper load bearing surface of the lift car
- fig. 8 shows a view corresponding to fig. 7 whereby the service and assembly platform is in its swung-out working position
- figs. 9 - 11 show partial views in perspective of a safety arrangement included in the lift system.
- Figs. 1 - 4 show a lift system according to the invention comprising a mast 1 constructed from a number of mast sections 2 stacked and mounted on top of each other and a lift car 3, which by means of guide rollers in a familiar manner can be moved along vertical tubes on the mast.
- the lift car 3 is furthermore in a familiar manner equipped with a motor that by means of a pinion engages with a gear rack on the mast 1.
- a motor that by means of a pinion engages with a gear rack on the mast 1.
- the expression lift car 3 as used in the following regards essentially known and existing car types for the carriage of people or goods that are used in lift systems where the mast 1 is constructed of a number of sections 2 mounted on top of each other and where the mast is intended via stay elements 4 to be anchored at regular intervals to a nearby building structure 5, which in fig.
- the roof of the cage type lift car 3 forms an upper working platform 6, which, on this type of lift car, is not normally used for carrying people and materials but is instead intended to be used for erecting the mast and for servicing.
- the said upper working platform 6 has both an upper essentially surrounding protective railing 7 and a lower surrounding protective edge 8 where the latter is used to prevent tools and the like that have been placed on the floor 9 of the working platform 6 from falling down.
- the upper working platform 6 is usually used as a load carrying surface for transporting mast sections 2 up and down from the top of the mast and as a working platform for personnel erecting and tearing down the mast sections.
- the upper working platform 6 is also used for bracing and anchoring the mast with stay elements 4 to the nearby building structure 5.
- the aforesaid can essentially be said to be known for this type of lift system and in order to achieve a lift system based on this that further improves accessibility when working on the mast and its erection, the lift car 3, as should be evident with a closer inspection of figs. 1 - 4, is equipped with a horizontally pivoted assembly and service platform, generally designated 10.
- the aforesaid pivoted assembly and service platform 10 has a principally rectangular and essentially level load bearing bottom 11 , the area of which has been chosen to support at least one person assigned with the task of carrying out assembly and service work, such as cleaning or tearing down the mast 1 and anchoring or undoing the stay elements 4 between the mast 1 and the nearby building structure 5. Since the pivoted assembly and service platform 10 is intended to be used to support a person, it has been designed like a cage with surrounding protective railing 12 and also a surrounding protective edge 13 that abuts the bottom 11 of the platform for preventing tools or the like placed on the said bottom from falling down from the platform.
- the service and assembly platform 10 is pivot mounted in a first bearing 14 at one end 15 of a swing arm 16 so that it swings around a vertical axis A and via the other end 17 of the swing arm and a second bearing 18 is pivot mounted on the lift car 3 to carry out a pivoting motion around a vertical axis B.
- the swing motion of the assembly and service platform 10 in a horizontal plane is illustrated with the two double arrows in fig. 5.
- the embodiment described herein has its first bearing 14 between one peripheral edge of the assembly and service platform 10, which here comprises one of its short ends, and the swing arm 16 by means of interaction between a swivel shaft 19 and swivel sleeve 20 while, from a loading point of view, the more critical second bearing 18 for the swing arm attachment to the lift car 3 is attained through interaction between a swivel shaft 22 extending along one side wall 21 of the cage type lift car 3 and a first and a second in-line swivel sleeve 23, 23'.
- a swivel shaft 22 extending along one side wall 21 of the cage type lift car 3 and a first and a second in-line swivel sleeve 23, 23'.
- one of the swivel sleeves 23 is fixed to the roof that serves as a working platform 6 of the lift car 3 and the other swivel sleeve 20' is fixed to the floor 24 of the lift cage.
- a first means of locking 25 has been arranged to lock the assembly and service platform 10 relative to the swing arm 16 and a second means of locking 26 for locking the swing arm 16 relative to the lift car 3.
- the first means of locking 25 comprises a brake 27 and a set screw 28, which by means of a handle 29 can be driven to a braking position against the swivel shaft 19.
- the second means of locking 26 comprises an elongated flat iron 30 that is swivel mounted at one end 31 to the lift car 3 and with which a relative locking action between the swing arm 16 and the lift car 3 is obtained through the interaction between a slotted hole 32 running essentially along the length of the entire flat iron and a set screw 33 arranged in the swing arm and extending through the hole.
- a slotted hole 32 running essentially along the length of the entire flat iron
- a set screw 33 arranged in the swing arm and extending through the hole.
- the assembly and service platform 10 can swivel freely within two separate horizontal planes that in fig. 5 are designated C and D respectively, whereby the first horizontal plane C is defined by the first swivel bearing 14 and the second horizontal plane D is defined by the second swivel bearing 18. That is to say, in the area of the swing arm's 16 swivel connection with the assembly and service platform 10 and in the area of the swing arm's 16 swivel connection with the elevator car 3.
- the first horizontal swivel plane C between the service and assembly platform 10 and the swing arm 16 on the one hand and the second horizontal swivel plane D between the swing arm 16 and the elevator car 3 on the other hand are situated at different levels in height, it is possible swing the assembly and service platform 10 and the swing arm 16 freely in relation to each other. Thanks to the assembly and service platform 10 on one peripheral edge being flexibly connected to the swing arm 16, the swivel planes C and D being situated at different levels where the latter swivel plane B is also situated above the roof of the elevator car 3 that serves as an upper working platform 16, the assembly and service platform 10 as well as the swing arm 16 can be swung freely in relation to the said elevator car 3 working platform 6 and the position of rest shown in fig. 3.
- the swivelling assembly and service platform 10 can be moved to a position at which it extends relatively far out from the elevator car 3 in the direction of the adjacent building structure 6 as shown in fig. 2. That is to say, to the service position that is normally difficult to access from the elevator car for fixing one end of the stay element 4 to the building structure 5.
- the advantage is also achieved that the assembly and service platform 10 can be swung into an essentially folded position of rest in conjunction with the elevator car 3, whereby the assembly and service platform 10 is retracted in a position above the swing arm as shown in fig. 2.
- the added advantage is achieved that the assembly and service platform 10 can be swung essentially around the mast 1 and consequently operated to the normally difficult to access service position at that part of the elevator mast, viewed from the elevator car 3, that constitutes the rear or the mast.
- the surrounding protective railing 7 that this type of elevator car is fitted with has been modified somewhat. A closer look at fig.
- the protective railing 7 has been modified in such a way that it has been divided and finished in a first 35 and a second end 36 that between them define an opening.
- the said opening is so adapted that the assembly and service platform 10 can be received in the opening when it is swung into its position of rest.
- the first 35 and second end 36 of the protective railing 7 like the assembly and service platform 10 have hereby been adapted in such a way that the swung-in assembly and service platform 10 forms part of the protective railing 7 and lower protective edge 8 surrounding the elevator car 3.
- a gate 37 swivel mounted on one free end of the protective railing 7 (see fig. 1).
- This gate 37 is designed with both an upper rail 38 and a lower protective edge 39 and, as illustrated by the double arrow 40, it can be swung around a vertical axis E to a locking position at the second free end 36 of the protective railing 7 and secured by a means of locking 41 acting between these parts when the assembly and service platform 7 is in a position swung out from the elevator car 3.
- a position sensing switch 40 has been arranged to detect when the assembly and service platform 7 is in an operating position swung out from the elevator car.
- the said switch 40 comprises a limit switch connected to the drive circuit for the elevator car 3 drive motor.
- the limit switch is so arranged to the swivel shaft 22 that it detects the relative angle of rotation of the shaft.
- FIGs. 7 and 8 show the elevator system according to the invention in an alternative embodiment, which essentially differs from the first embodiment described above in that the assembly and service platform's 10 flexible connection with the elevator car 3 via the swing arm 16 is arranged at a level situated essentially above the roof serving as a working platform 6 above the elevator car 3 or the bottom surface 9.
- the swivel bearing 18 for swinging the swing arm 16 relative to the elevator car 3 and thereby also for swinging the assembly and service platform 10 around the axis B relative to the elevator car is arranged at such a height above the elevator car's 3 working platform 6 that both swivel planes C and D, within which the assembly and service platform 10 can be swung freely, are above the protective railing 7 that runs around the periphery of the working platform. From the swung-in position of rest shown in fig.
- the assembly and service platform 10 can be swung freely both above the roof surface 9 of the elevator car 3 serving as a working platform 6 and out to a position at which it extends relatively far out from the elevator car 3 in a direction towards, for instance, an adjoining building structure for bracing the mast 1 with a stay element 4 or for relative attachment of the stacked mast sections 2.
- a stand 41 is arranged in conjunction with one end of the elevator car.
- the stand 41 comprises a tubular swivel sleeve 42 that can be said to form a upward vertically extending extension of the swivel bearing for the arm 16 shown in fig. 1.
- the swivel sleeve 42 in the stand 41 is at one end 43 attached to the bottom surface 9 of the working platform 6 and at its upper free second end 44 braced to the bottom surface 9 via stay elements 45 extending diagonally between the upper free second end of the swivel sleeve 42 and the bottom surface 9.
- the swivel sleeve 42 hereby serves as a bearing and receptacle for a swivel shaft that can essentially be said to correspond to the swivel shaft designated 22 in fig. 1.
- the swivel bearing 18 for the swing arm's 16 flexible attachment to the elevator car 3 is hereby achieved through the interaction between the said swivel shaft 22 and swivel sleeve 42.
- Figs. 9 - 11 show an example of an arrangement that further improves safety when working on the assembly and service platform 10 and prevents inadvertent operation.
- the safety arrangement is used to prevent the assembly and service platform 10 from being inadvertently swung out from its parked position above the roof of the elevator car
- a blocking device 50 comprising a first gear ring 51 positioned in conjunction with the first bearing 14 between the swing arm 16 and the assembly and service platform 10, and a second gear ring 52 situated in conjunction with the second swivel bearing 18 between the swing arm 16 and elevator car 3.
- the blocking device also includes a pawl 53, 54 arranged to each of the gear rings 51 , 52 that when engaged in their respective gear rings 51, 52 will block the respective swivel bearings 14, 18 and thereby also prevent the assembly and service platform from swinging relative to the elevator car 3.
- the pawls 53, 54 are interlinked via a linkage system generally designated 55, which, via a shaft 56 extending through a central opening 57 in the first bearing 14 between the swing arm 16 and the assembly and service platform 10, is in connection with the operating handle 58 in the assembly and service platform 10 and with which operating handle the pawls can be operated.
- a linkage system Arranged to the linkage system is a spring device 59 through the action of which the linkage system is loaded in such a way that the assembly and service platform cannot be operated or swung without an operator actively releasing the engagement of the pawls 53, 54, in the gear rings 51, 52 via the operating handle 58.
- the gate 37 is swung out from its normal position to a locked position at the free end 36 of the protective railing 7, so forming a continuous surrounding protective railing as shown in fig. 1.
- the first 25 and second means of braking 26 will be switched to their respective active braking positions so that the assembly and service platform will remain in a fixed position relative to the elevator car.
- the first 25 and second means of braking 26 will return to their respective non-braking positions, after which the assembly and service platform 7 is swung back to its position of rest at the elevator car once the gate 37 has been swung into its inactive normal position.
- the present invention is not limited to the above description or as illustrated in the drawings but can be changed and modified in a number of different ways within the framework of the idea of invention specified in the following claims.
