Description
Technical field
The present invention relates to the railway hopper car for goods and materials such as transportation iron ores, refer to a kind of device for regulating gap of bottom door of railway hopper car particularly.
Background technology
The bottom door of railway hopper car mainly is made up of the left and right sides door leaf of splitting, the reservoir that opens the door, supplementary reservoir, hook with safety tong and parts such as switching reservoir, curved bar and crank thereof.The bottom door of this version has the advantages that aperture is big, be fit to quick unloading.But its poor sealing guarantees at closing time, and this is by curved bar and crank left and right sides door leaf to be drawn over to one's side to make overlapping the closing of its butt joint because of closing the door, and this just has relatively high expectations to the gap of left and right sides door leaf.Particularly by after the use of a period of time, owing to reasons such as left and right sides door leaf distortion, bearing pin and lining abrasion, the bottom door gap will inevitably occur and become big phenomenon, and the gap can't regulate, cause cargo leakage, the operation of influence safety.
Summary of the invention
Purpose of the present invention be exactly to provide a kind of simple in structure, easy to operate, economical and practical, can eliminate the device for regulating gap of bottom door of railway hopper car in door leaf gap, the left and right sides.
For achieving the above object, the device for regulating gap of bottom door of railway hopper car that the present invention is designed, has a permanent seat on the side door fan end plate that can be fixed on bottom door, outside the described permanent seat, interior both sides are respectively arranged with blocked ear and bearing seat, be provided with an adjusting shaft in the concentric axis hole of described blocked ear and bearing seat, the thread segment that described adjusting shaft is positioned at the blocked ear outside is provided with setting nut, the thread segment that described adjusting shaft is positioned at the blocked ear inboard is provided with hold-down nut, described adjusting shaft is positioned at polished rod section and the bearing seat interference fit at bearing seat place, the inboard termination of described adjusting shaft can link to each other with curved bar by bearing pin, and described curved bar is to link to each other with crank on the opposite side door leaf that is installed in bottom door.
Principle of work of the present invention is such: because a side door of permanent seat and bottom door fan is linked as integral body, link to each other with curved bar on being installed in the opposite side door leaf and be installed in the inboard termination of the adjusting shaft on the permanent seat, and the polished rod section of adjusting shaft and the bearing seat flush fit of permanent seat can stably be delivered to the power on the curved bar on the door leaf.When turning setting nut and hold-down nut when changing relative distance between adjusting shaft and the permanent seat, curved bar and crank mechanism will force left and right sides door leaf to move, thereby regulate the bottom door gap.
The invention has the advantages that: only needing increases a permanent seat and adjusting shaft assembly between the curved bar of the side door fan of bottom door and opposite side door leaf, just can regulate the distance between the door leaf of both sides easily, thereby effectively eliminate the bottom door gap.Simultaneously its simple in structure, processing ease, with low cost is very suitable for existing bottom door of railway hopper car is transformed renewal, guarantees that shipping do not have leakage.

Fig. 2 is equipped with the structural representation of bottom door of railway hopper car of the present invention under in off position;
Fig. 3 is structure for amplifying scheme drawing of the present invention used among Fig. 2;
Fig. 4 is the plan structure scheme drawing of Fig. 3.
The specific embodiment
The present invention is described in further detail below in conjunction with the drawings and specific embodiments:
Bottom door of railway hopper car shown in the figure is made of the left side door leaf of splitting 1 and right side door leaf 6, by the curved bar 4 that is articulated and connected and the rotation of crank 5, drive left side door leaf 1 and 6 rotations of right side door leaf, realize the switching process, its propulsion source is the switching reservoir 7 that links to each other with crank 5.Curved bar 4 is originally and directly is hinged on the left side on the door leaf 1, and 5 on crank directly is hinged on the right side door leaf 6, and both connect the clearance t that relative distance between the bearing pin has determined bottom door
1
Device for regulating gap of bottom door shown in the figure mainly is made up of the parts such as adjusting shaft 3, setting nut 11 and hold-down nut 9 of permanent seat 2, band adjusting screw thread.Permanent seat 2 is weldingly fixed on the end plate of above-mentioned left side door leaf 1, outside the permanent seat 2, interior both sides have been designed blocked ear 21 and bearing seat 22 respectively, be interspersed with an adjusting shaft 3 in the concentric axis hole of blocked ear 21 and bearing seat 22, adjusting shaft 3 is positioned to screw on the thread segment in blocked ear 21 outsides setting nut 11, adjusting shaft 3 is positioned to screw on the thread segment of blocked ear 21 inboards hold-down nut 9, adjusting shaft 3 is positioned at polished rod section and bearing seat 22 interference fit at bearing seat 22 places, the inboard termination of adjusting shaft 3 links to each other with an end of curved bar 4 by bearing pin 8, the other end of curved bar 4 links to each other with crank 5, and crank 5 is hinged on the right side door leaf 6.
The present invention can effectively adjust because of bearing pin 8 and lining abrasion and the long-term bottom door clearance t of using the back distortion to cause
1Change.After left side door leaf 1 and right side door leaf 6 are in place substantially, with setting nut 11 adjusting shaft 3 stretchings are put in place, again with hold-down nut 9 lockings, to prevent adjusting shaft 3 plaies, at last lock washer with double ears 10 is fitted with permanent seat 2, setting nut 11, hold-down nut 9 respectively, prevent that it is loosening.For the sake of assurance, can be with setting nut 11 and permanent seat 2 spot welding, when needs are regulated the bottom door gap, remove the spot weld between setting nut 11 and the permanent seat 2, perk lock washer with double ears 10, unclamp hold-down nut 9, turn setting nut 11 to regulate the relative position t between permanent seat 2 and the adjusting shaft 3
2, up to the bottom door clearance t
1Reach till the requirement, screw on again hold-down nut 9 and lock washer with double ears 10 get final product setting nut 11 and permanent seat 2 spot welding again.
Because the adjusting in bottom door gap only just can realize with the relative position of adjusting shaft 3 by turning nut 11 adjustment permanent seats 2, need not dismantle other parts, and is easy to operate reliable.If fracture appears in the blocked ear in permanent seat 2 outsides 21, permanent seat 2 inboard bearing seats 22 with adjusting shaft 3 interference fit also can block adjusting shaft 3, do not cause bottom door all to be opened suddenly, play certain safety precaution effect.
