[0040] This embodiment provides a well repair elevator straightening device, which is used to straighten the elevator 100 through the suspension rod 200.

Figure 1 Move in the direction of the Z axis as shown in ).

[0043] One end of the telescopic mechanism 500 is connected to the sliding mechanism 400, and the other end of the telescopic mechanism 500 is suitable for connecting the suspension rod 200. The telescopic mechanism 500 can drive the suspension rod 200 to move along the X-axis direction, and adjust the position of the suspension rod 200 in the X-axis direction through telescopic action, so as to control the elevator 100 to grab and avoid the drill pipe. At the same time, when the telescopic mechanism 500 is not performing telescopic operation, the suspension rod 200 and the sliding mechanism 400 are fixedly connected. The sliding mechanism 400 and the longitudinal guide mechanism 300 are mutually limited on the plane where the XY axis is located, so that the telescopic mechanism 500 can control the elevator 100 not to have lateral displacement during operation.

[0044] The well repair elevator straightening device described in this embodiment is configured by arranging a longitudinal guide mechanism next to the boom, and connecting the boom and the longitudinal guide mechanism through a telescopic mechanism and a sliding mechanism, so that the boom is lifted and lowered along the longitudinal guide mechanism. At the same time, the telescopic mechanism controls the boom to move along the X-axis direction for straightening. The longitudinal guide mechanism limits the boom laterally through the telescopic mechanism and the sliding mechanism, ensuring that the elevator grabs the drill rod and arranges / delivers the rod in the correct direction.

[0045] Specifically, based on the above embodiments, this embodiment provides a specific implementation method that is easy to implement to better achieve the above functions, but does not limit the well repair elevator righting device described in the present invention to only adopt the following one implementation method.

[0046] Specifically, combined Figures 1 to 6 As shown, the longitudinal guide mechanism described in this embodiment includes two tensioning steel wires 310 extending longitudinally and parallel to each other. Optionally, a longitudinal steel pipe or other structure may also be used. The sliding mechanism 400 includes a connecting rod 410 and sliding members 420 arranged at both ends of the connecting rod 410. The two sliding members 420 at both ends are respectively slidably connected with the two tensioning steel wires 310. The connecting rod 410 is suitable for fixing the two tensioning steel wires 310 in the direction of the Y axis as an integrated structure. The sliding member 420 and the tensioning steel wire 310 are suitable for longitudinal relative movement and transverse mutual limitation, that is, the sliding member 420 can move along the tensioning steel wire 310 only in the Z axis direction.

[0047] Specifically, combined Figure 4As shown, the sliding member 420 is provided with two side plates 421 and at least two pulleys 422. In this embodiment, each sliding member 420 is provided with 4 pulleys 422, and the four pulleys 422 are connected in a square shape and located at the four vertex positions of the square. The pulleys 422 are all located between the two side plates 421, the tensioning steel wire rope 310 passes through between the pulleys 422, and the sliding member 420 and the tensioning steel wire rope 310 are adapted to move longitudinally relative to each other and be limited transversely to each other.

[0048] Specifically, in combination with Figure 2 as described, the longitudinal guiding mechanism 300 further includes a tensioning device, and the tensioning device can adopt a turnbuckle or a winch, etc., and preferably adopts a turnbuckle. The tensioning device is located at the bottom end of the tensioning steel wire rope 310 and is adapted to adjust the tightness of the tensioning steel wire rope 310. Preferably, the top end of the tensioning steel wire rope 310 is fixed on the derrick, and the bottom end of the tensioning device is fixed on the drill floor.

[0049] Specifically, the telescopic mechanism 500 includes a telescopic member 510, a cylinder 520 and a cross bar 530. The cross bar 530 extends along the Y-axis direction, and the cylinder 520 and the telescopic member 510 both extend along the X-axis direction.

[0050] The telescopic member 510 includes a telescopic rod 511 and a guide rod 512. The guide rod 512 has a hollow cavity 5121. The telescopic rod 511 is adapted to partially extend into the hollow cavity 5121 and move relative to the guide rod 512. One end of the guide rod 512背离 the telescopic rod 511 is connected to the sliding member 420, and one end of the telescopic rod 511背离 the guide rod 512 is connected to the cross bar 530. There are two telescopic members 510 and they are arranged in parallel on both sides of the cylinder 520. The telescopic rod 511 is adapted to extend into the hollow cavity 5121, and the guide rod 512 is adapted to limit the telescopic rod 511 in the YZ plane. The telescopic rod 511 can only displace along the X-axis.

[0051] The telescopic member 510, the cross bar 530, the sliding member 420 and the sliding member 420 form a frame structure. The two ends of the cylinder 520 are respectively connected to the cross bar 530 and the connecting rod 410 to form a structure similar to a "day" character, which improves the structural strength of the telescopic mechanism 500. At the same time, the frame structure formed by the combination of the telescopic mechanism 500 and the sliding mechanism 400, combined with the two longitudinally arranged tensioning steel wire ropes 310, can better limit the Y-axis direction of the suspension rod 200, and further correct the Y-axis direction of the elevator 100.

[0052] Preferably, in combination with Figure 7As shown, the guide rod 512 is provided with a first transverse adjustment hole 5122, the first transverse adjustment hole 5122 is a waist-shaped hole and has a larger length along the X-axis direction. Preferably, the ratio of the length of the first transverse adjustment hole 5122 along the X-axis direction to the length of the guide rod 512 along the X-axis direction is in the range of 1 / 3 to 2 / 3. The telescopic rod 511 is provided with a plurality of through holes 5111, and the plurality of through holes 5111 are arranged along the X-axis direction. The telescopic member 510 is suitable for being connected with the through holes 5111 at the first transverse adjustment hole 5122 through a connecting member. When the telescopic rod 511 is telescoped in the guide rod 512, the pin or bolt can only be displaced in the first transverse adjustment hole 5122 along the X-axis direction. The first transverse adjustment hole 5122 is suitable for limiting the relative displacement between the telescopic rod 511 and the guide rod 512 to prevent the telescopic rod 511 from being separated from the guide rod 512. It should be noted that the connecting piece described in this embodiment includes detachable connecting parts such as bolts and pins.

[0053] The cross bar 530 is fixedly connected to the suspension rod 200. Preferably, the cross bar 530 is detachably fixedly connected to the suspension rod 200 via the connecting member 600. Figure 5 As shown, the connector 600 includes a holder 610 and a mounting support 620. The holder 610 has a U-shaped hoop similar to a climbing member. The holder 610 surrounds and fixes the suspension rod 200. On the other side, the holder 610 and the mounting support 620 are fixedly connected by a pin, and the mounting support 620 is fixedly connected to the cross bar 530. Specifically, the cross bar 530 and the two suspension rods 200 are connected by the connector 600 to improve the limiting effect of the cross bar 530 on the suspension rod 200.

[0054] Better, combined Figure 5 and Figure 8 As shown, the connecting member 600 further includes an adjustment plate 630, which is installed between the mounting support 620 and the cross bar 530. The adjustment plate 630 is fixedly connected to the cross bar 530. Preferably, the adjustment plate 630 and the cross bar 530 are both metal parts, and the adjustment plate 630 is welded and fixed to the cross bar 530. The adjustment plate 630 is provided with a second transverse adjustment hole 631, which is a long waist-shaped hole extending along the Y-axis direction. The mounting support 620 is suitable for being fixed at different positions of the second transverse adjustment hole 631 by bolts. The second transverse adjustment hole 631 is suitable for adjusting the Y-axis installation position of the mounting support 620, thereby adjusting the relative position of the two suspension rods 200 along the Z-axis direction to match a variety of different gears and models of elevators 100.

[0055] Preferably, this embodiment provides a specific implementation method of designing the well repair elevator straightening device as a detachable and foldable structure based on the above implementation method. Figures 3 to 6 As shown, the two ends of the cylinder 520 are respectively hinged with the cross bar 530 and the connecting rod 410; two longitudinal ear plates 5123 extend up and down from one end of the guide rod 512 close to the sliding member 420 (on the side opposite to the X-axis), and the two longitudinal ear plates 5123 are both hinged with the sliding member 420. Specifically, the longitudinal ear plates 5123 extend between the two side plates 421 and are then hinged with the side plates 421. When the telescopic mechanism 500 is connected to the suspension rod 200 and works, the two longitudinal ear plates 5123 of the guide rod 512 are both connected with the sliding member 420, and the telescopic mechanism 500 is horizontal as a whole. When the telescopic mechanism 500 is not needed to be straightened, the pin connecting the holder 610 and the mounting bracket 620 is disassembled, and the pin connecting the longitudinal ear plate 5123 above the guide rod 512 and the sliding member 420 is disassembled. At this time, the telescopic mechanism 500 is separated from the suspension rod 200, and the telescopic mechanism 500 is only rotatably connected to the sliding mechanism 400 through the longitudinal ear plate 5123 on the lower side, and the cylinder 520 is rotatably connected to the sliding mechanism 400 through the pin. The telescopic mechanism 500 can be as shown in FIG. Figure 6 When the structure described in this embodiment no longer needs to be straightened, the telescopic mechanism 500 and the suspension rod 200 can be disassembled in time, and the telescopic mechanism 500 can be folded and recovered to prevent the telescopic mechanism 500 from interfering with other equipment.

[0056] The well repair elevator righting device described in this embodiment realizes multi-directional righting and folding functions through only one cylinder through structural design, and has a simple structure.

[0057] Preferably, the pin axis connecting the cylinder 520 and the connecting rod 410 and the pin axis connecting the guide rod 512 and the sliding member 420 are not colinear; that is, the three pins connecting the telescopic mechanism 500 and the sliding mechanism 400 form a triangular structure. After the holder 610 and the mounting bracket 620 are disassembled, the pin between the cylinder 520 and the connecting rod 410 and the pin between the guide rod 512 and the sliding member 420 support each other. At this time, the telescopic mechanism 500 can be electrically folded by controlling the extension and retraction of the cylinder 520, without the need for an operator to perform the folding, and the degree of mechanization is higher.

[0058] Better, combined Figure 3As shown, the cylinder 520 is hinged to the cross bar 530 through an adapter frame 540, one end of the adapter frame 540 is fixedly connected to the cross bar 530, and the other end of the adapter frame 540 extends obliquely downward toward a side away from the cylinder 520 and is hinged to the pin of the cylinder 520. This structure can increase the telescopic stroke of the cylinder 520. When the length of the cylinder 520 body is long, it is not necessary to design a long telescopic member 510 and still have a long telescopic stroke.

[0059] Better, combined Figure 1 As shown, the well repair elevator straightening device further includes a connecting rope 700, and the two ends of the connecting rope 700 are respectively connected to the crane and the sliding mechanism 400. On the one hand, the connecting rope 700 can suspend the sliding mechanism 400, and when the crane lifts the suspension rod 200 upward, the sliding mechanism 400 can be lifted at the same time to ensure the integrity of the well repair elevator straightening and lifting. On the other hand, when the clamping seat 610 and the mounting support 620 are removed and the telescopic mechanism 500 is folded, the connecting rope 700 can suspend the telescopic mechanism 500 and the sliding mechanism 400 to prevent the telescopic mechanism 500 and the sliding mechanism 400 from falling.

[0060] Although the present invention is disclosed as above, the protection scope of the present invention is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications will fall within the protection scope of the present invention.
