This invention relates to new and useful improvements in drilled wellequipment, land more particularly to a conveyer for removing drill pipes from the well proper after the completion of a well and racking the same in joints at a predetermined location adjacent thewell.
The principal object of the present invention is to provide a conveyer of the character stated which will simplify the work of dismantling and racking drill stems to a substantial amount.
Another important object of the invention is to provide an apparatus of the character stated which can be adjusted to meet varying conditions at a well.
Other objects and advantages of the invention will become apparent to the reader of the following description.
In the drawings:
Figure 1 represents a top plan View.
Figure 2 is a bottom plan View.
Figure 3 is a back end elevational vew.
Figure 4 is a front end elevational view.
Figure 5 is a fragmentary vertical sectional view taken substantially on line 5-5 of Figure 1.
Figure 6 is a sectional view taken substantially on line 6 6 of Figure 1.
Figure 7 is a perspective View of the trigger.
Figure 8 is a fragmentary detailed sectional view through the upper portion of one of the skids.
Figure 9 is a sectional view through one of the :,7..
Referring to the drawings wherein like numerals designate like parts, it can be seen that numerals 5 and 6 denote base numbers which are preferably provided with spurs or the like l on the bottoms thereof to prevent slippage.
On the end of the apparatus which must rest on the usual wooden platform of the well (not shown), a post 6 is provided for its base member 6 and fits into a socket 9, it being observed in Figure 5 that the lower end or" the post 8 is formed with vertically spaced openings I6 to accommodate a post II which passes through the socket 9. Thus, it can be seen that this post 8 can be adjusted vertically to compensate for different height well platforms.
On the other base member 5 is a rigid upstanding post I2 and the posts 8 and I2 are connected by a brace member I3. Inclined brace members I4 are provided for the post I2. It is also preferable that a tubular connector I5 be provided between the base members 5 and 6 to further reinforce and strengthen the structure.
Numeral I6 denotes an elongated troughshaped runway open at its end and formed with a longitudinally extending slot I1 through which depend neck structures I8 and I9 depending from corresponding dollies 20 and ZI, the dolly 2| being provided with an end wall 22 to serve as an abutment for the engaging ends of drill stem joints.
V-shaped rails 23, 23 are provided on the bottom of the runway I6 and are engaged by the grooved Wheels 24 of carriages 25 which support the dollies 26 and 2l, it being observed in Figures 3 and 4 that the aforementioned necks I8 and I9 depend through the slot I1 and are secured to additional carriages 26 equipped with V-grooved rollers 2l which ride V-shaped rails 28 on the bottom side of the trough-shaped runway I6.
A cable 29 extends from the carriage 26 of the dolly 26 to a spring wound drum 30, while a cable 3| extends from the dolly 2| to a spring Wound drum 32.
An arm 33 has one end disposed through an opening in the upper end of the post I2 and is secured in place by a nut or the like 34. This end portion of the runway I6 has a lug 35 and to this lug the arm 33 is pivotally secured, as at 36.
Additional arms 3l, 3l extend laterally from the runway I6 and are connected at their free ends by springs 38 to the brace I3.
On the brace I3 are joint structures generally referred to by numeral 39. Each of these joint structures comprises a collar 40 suitably secured to the brace member I3 and having a link member 4I pivotally secured thereto. This link member 4I is pivotally secured to another link member i2 and this in turn is pivotally secured to a lug 43 carried by the runway I6. A strip spring 44 assists in holding the links 4I and 42 straight.
At the joint of the links 4I, 42 is a laterally disposed arm 45.
As is clearly shown in Figure 2, an elongated control rod 46 connects the arms 45, 45 of the joints 39 and extends to connect to an eye 41 of a trigger 48, which extends through a bearing 49 and is held in an upright position, as suggested in Figures 2 and 3 by a spring 56 which extends from the rod 46 to connect to the brace member I3 (see Fig. 1).
Skids generally referred to by numeral 5I are provided for the opposite side of the runway I6 from the location of the posts B and I2, and these skids each comprises a tube 52 having its upper end apertured to receive an elongated rod 53 which has its ends anchored to the runway I6, as at 54, 54. The brace members 55, 55 extend fronaeach tube 52 obliquely to connect to the rod An elongated leg 55 is provided for each tube 52 and has its upper end disposed into the tube, while its lower` end is equipped with a roller 51. The upper portion of the leg 56 is formed with a plurality of longitudinally spaced openings 58 for receiving a cross-pin 59 disposed through the tube 52.
In the operation of the mechanism, it can be seen that a pipe joint is lowered from the derrick rigging with one end disposed onto the dolly 2l, the pipe joint being moved over the runway IB from the right in Figure 1. When the pipe joint has been brought to rest on both dollies 2| and 22, it is forced longitudinally of the runway I6 until the dolly 2| strikes the trigger 48, which in turn breaks the joints 39 permitting the runway IB to be tilted downwardly to the end that the drill stem joint denoted by numeral 6l)v can roll oi of the dollies 20 and 2l and down the skids ,j
5I to pile up on a designated rack.
While the foregoing specification sets forth the invention in specic terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.
Having described the invention, what is claimed as new is:
1. In apparatus of the class described, a base including a pair of posts, a member forming a horizontal runway and pivotally mounted on said posts for vertical tilting, a dolly mounted on said member to travel along the runway, means to block tilting of said member comprising pairs of break joint links extending between the base and said member, and means operative by travel of said dolly to break the joints in said pairs of links.
2. In apparatus of the class described, a base including a pair of posts, a member forming a horizontal runway and pivotally mounted on said posts alongside the same for vertical tilting, a
dolly mounted on said member to travel along the same, counterbalancing means for said member for preventing the same from tilting downwardly normally and including a pair of lever forming arms extending from one side thereof, and springs connected to said arms and to said base, means to block downward tilting of said member comprising pairs of break joint links extending between the base and said member, and means operative by travel of the dolly to break the joints in said pairs of links.
