Technical Field

[0001] This utility model relates to the technical field of disassembly equipment for drive wheel assemblies of downhole crawlers, and particularly to a device for assembling and disassembling drive wheel assemblies of downhole crawlers. Background Technology

[0002] The assembly and disassembly of the drive wheels of downhole crawlers is a crucial step in the maintenance of logging instruments. With the continuous development of oil exploration technology, downhole crawlers, as essential tools in the exploration process, are vital for the smooth progress of exploration work. However, in practical applications, the drive wheels of downhole crawlers may become damaged or require repair, necessitating disassembly and maintenance.

[0003] Traditionally, assembling and disassembling the drive wheel assembly of a downhole crawler involves using common tools such as screwdrivers, needle-nose pliers, and hammers. This method is time-consuming and prone to damaging the crawler drive wheel assembly due to the difficulty in controlling the precise location and striking force. Utility Model Content

[0004] This application provides a disassembly and assembly device for assembling and disassembling the drive wheel assembly of a downhole crawler. The device can accurately locate the assembly and disassembly positions of the drive wheel assembly, enabling rapid disassembly and installation of the drive wheel assembly, improving disassembly and assembly efficiency, and reducing operational risks.

[0005] This application provides a disassembly and assembly device for assembling and disassembling a drive wheel assembly of a downhole crawler, comprising: a base, on which a first limiting member is provided, the first limiting member being able to limit the drive wheel assembly along the circumference of the drive wheel assembly; a frame, mounted on the base; and a lead screw assembly, including a lead screw and a female thread, the lead screw being mounted on the frame and extending along a first direction, the lead screw being rotatably connected to the frame along the first direction, and the female thread being fixedly mounted on the end of the lead screw facing the base, the first direction being parallel to the axial direction of the lead screw.

[0006] According to the aforementioned embodiments of this application, the first limiting member is a plurality of limiting posts, which are spaced apart on the base along the circumferential direction of the drive wheel assembly.

[0007] According to any of the foregoing embodiments of this application, a second limiting member is further included, wherein the first limiting member is mounted on the base, and the second limiting member is capable of limiting the drive wheel assembly along the first direction.

[0008] According to any of the foregoing embodiments of this application, the second limiting member includes a limiting screw and a limiting plate. The limiting screw is detachably connected to the base in a first direction, and the limiting plate is provided with a limiting hole or a limiting groove that cooperates with the limiting screw.

[0009] According to any of the foregoing embodiments of this application, the limiting screw includes a first limiting screw and a second limiting screw, and the limiting plate is provided with limiting holes or limiting grooves that respectively cooperate with the first limiting screw and the second limiting screw.

[0010] According to any of the foregoing embodiments of this application, the first limiting screw and the second limiting screw are symmetrically distributed relative to the plane where the lead screw is located.

[0011] According to any of the foregoing embodiments of this application, the frame is U-shaped in general. The frame includes two longitudinal beams and one transverse beam. Both longitudinal beams extend along a first direction and are fixedly connected to the base. The transverse beam is disposed between the two longitudinal beams and extends along a second direction. The first direction is perpendicular to the first direction.

[0012] According to any of the foregoing embodiments of this application, the two longitudinal beams are symmetrically arranged relative to the transverse beam.

[0014] According to any of the foregoing embodiments of this application, the assembly and disassembly device further includes an operating handle, which is connected to the end of the lead screw away from the base.

[0015] This application discloses a disassembly and assembly device for assembling and disassembling drive wheel assemblies of downhole crawlers. When assembling and disassembling the drive wheel assembly is required, the drive wheel assembly can be placed on a base. A first limiting member on the base can limit the circumferential movement of the drive wheel assembly. Then, the female thread of the lead screw assembly is aligned with the part of the drive wheel assembly to be disassembled. Rotating the lead screw causes the female thread to rotate, thereby disassembling the drive wheel assembly. The disassembly device of this application embodiment, by limiting the circumferential movement of the drive wheel assembly with the first limiting member, ensures the accuracy and stability of the disassembly process, avoiding disassembly failure or damage caused by accidental rotation or movement of the drive wheel. Simultaneously, the operator applies pressure through a simple rotational motion, thereby quickly and effectively disassembling the drive wheel assembly. Because the lead screw assembly can provide uniform and controllable pressure, the risk of damage to the drive wheel assembly due to excessive impact or improper operation is reduced.

[0025] The present invention will be further described below with reference to the accompanying drawings.

[0026] This application provides a disassembly and assembly device for assembling and disassembling the drive wheel assembly of a downhole crawler. The device can accurately locate the assembly and disassembly positions of the drive wheel assembly, enabling rapid installation and disassembly of the drive wheel assembly, improving installation and disassembly efficiency, and reducing operational risks.

[0027] Figure 1 This is a schematic diagram of the assembly and disassembly device for assembling and disassembling the drive wheel assembly of a downhole crawler, according to one embodiment of this application. Figure 1 As shown in the illustration, this application provides a disassembly and assembly device 1000 for assembling and disassembling a drive wheel assembly of a downhole crawler, including a base 100, a frame 200, and a lead screw 310 lead screw assembly 300. A first limiting member 110 is provided on the base 100, which can limit the drive wheel assembly M along its circumference. The frame 200 is mounted on the base 100. The lead screw 310 lead screw assembly 300 includes a lead screw 310 and a female thread 320. The lead screw 310 is mounted on the frame 200 and extends along a first direction. The lead screw 310 is rotatably connected to the frame 200 along the first direction, and the female thread 320 is fixedly installed at the end of the lead screw 310 facing the base 100. The first direction is parallel to the axial direction of the lead screw.

[0028] It should be noted that the first limiting member 110 provided on the base 100 can be a limiting groove that matches the shape of the drive wheel assembly M, or it can be a limiting protrusion or limiting post provided on the base 100. When it is necessary to disassemble the drive wheel assembly M, it can be placed on the base 100, and then the first limiting member 110 can limit the circumference of the drive wheel assembly M, preventing it from rotating or moving due to external forces during assembly and disassembly.

[0029] Understandably, once the drive wheel assembly M is placed on the base 100 and positioned by the first limiting member 110, the female thread 320 of the lead screw 310 is aligned and positioned with the detachable parts of the drive wheel assembly M. The parts to be installed and removed from the drive wheel assembly M can be disassembled by rotating the lead screw 310 and then driving the female thread 320 fixedly connected to the lead screw 310. The lead screw 310 and lead screw assembly 300 can provide more uniform and stable tension and pressure, thereby reducing the risk of damage due to improper operation.

[0030] In this embodiment, the female buckle 320, which is fixedly connected to one end of the lead screw 310 facing the base 100, has a shape (e.g., thread, slot, or snap) and size that matches the component to be disassembled in the drive wheel assembly M, so that the female buckle 320 can be physically connected to the component to be disassembled in the drive wheel assembly M by thread, snap, slot, or other means to complete the disassembly operation.

[0031] An assembly and disassembly device 1000 for assembling and disassembling a drive wheel assembly M of a downhole crawler, according to an embodiment of this application, allows for the assembly and disassembly of the drive wheel assembly M. When assembly and disassembly are required, the drive wheel assembly M is placed on a base 100. A first limiting member 110 on the base 100 limits the circumferential movement of the drive wheel assembly M. Then, the female thread 320 of the lead screw 310 assembly 300 is aligned with the part of the drive wheel assembly M to be disassembled. Rotating the lead screw 310 causes the female thread 320 to rotate, thus disassembling the drive wheel assembly M. The disassembly and assembly device 1000 of this embodiment limits the circumferential movement of the drive wheel assembly M through the first limiting member 110, ensuring accuracy and stability during disassembly and preventing disassembly failure or damage due to accidental rotation or movement of the drive wheel. Simultaneously, the operator applies pulling and pressure through simple rotational movements, thereby quickly and effectively disassembling the drive wheel assembly M. Because the lead screw 310 and lead screw assembly 300 can provide uniform and controllable tension and pressure, the risk of damage to the drive wheel assembly M due to excessive impact or improper operation is reduced.

[0032] like Figure 1-2 As shown, in some embodiments, the first limiting member 110 is a plurality of limiting posts. The plurality of limiting posts are arranged at intervals along the circumference of the drive wheel assembly M on the base 100.

[0033] In this embodiment, when the drive wheel assembly M is placed on the base 100, the limiting posts are spaced apart along the circumference of the drive wheel assembly M. The limiting posts provide multiple contact points in the circumference of the drive wheel assembly M, which can ensure that the drive wheel assembly M will not move or rotate along its circumference during disassembly, thereby increasing stability and making the disassembly process safer and more reliable.

[0034] like Figure 1-2 As shown, in some embodiments, the disassembly and assembly device 1000 further includes a second limiting member 120. The first limiting member 110 is mounted on the base 100, and the second limiting member 120 is capable of limiting the drive wheel assembly M along a first direction.

[0035] It is understood that the second limiting member 120 may be a clamping component or a limiting block provided on the base 100, so that the drive wheel assembly M placed on the base 100 can be clamped and fixed on the base 100, thereby improving the stability and accuracy during assembly and disassembly, and enhancing the overall safety and reliability.

[0036] In this embodiment, the second limiting member 120 can limit the drive wheel assembly M along the first direction. Cooperating with the first limiting member 110, it limits the drive wheel assembly M placed on the base 100 from two directions, enhancing the stability during disassembly.

[0037] like Figure 1-2 As shown, in some embodiments, the second limiting member 120 includes a limiting screw 121 and a limiting plate 122. The limiting screw 121 is detachably connected to the base 100 in a first direction. The limiting plate 122 is provided with a limiting hole or limiting groove that mates with the limiting screw 121.

[0038] In this embodiment, when it is necessary to disassemble the drive wheel assembly M, the drive wheel assembly M is first placed on the base 100, and then limited by the first limiting member 110. Then, the drive assembly is clamped on the base 100 by the cooperation of the limiting screw 121 and the limiting plate 122 provided on the base 100, and the drive wheel assembly M is limited in the first direction to ensure the safety and stability of the disassembly process.

[0039] like Figure 1-2 As shown, in some embodiments, the limiting screw 121 includes a first limiting screw and a second limiting screw, and the limiting plate 122 is provided with limiting holes or limiting grooves that respectively cooperate with the first limiting screw and the second limiting screw.

[0040] like Figure 1-2As shown, in some embodiments, a double-limiting screw 121 with a first limiting screw and a second limiting screw is used in conjunction with a limiting plate 122 to further enhance the limiting effect. This can accurately and stably limit the drive wheel assembly M in the first direction, preventing it from moving excessively or falling off.

[0041] like Figure 1-2 As shown, in some embodiments, the first limiting screw and the second limiting screw are symmetrically distributed relative to the plane where the lead screw 310 is located.

[0042] like Figure 1-2 As shown, in this embodiment, when the first and second limiting screws are symmetrically distributed relative to the plane of the lead screw 310, the limiting forces they exert on the drive wheel assembly M are balanced on both sides. This balance helps reduce structural distortion or deformation caused by excessive force on one side, thereby improving the stability and durability of the entire assembly / disassembly device 1000.

[0043] like Figure 1-2 As shown, in some embodiments, the frame 200 is generally U-shaped, and includes two longitudinal beams 210 and one transverse beam 220. Both longitudinal beams 210 extend along a first direction and are fixedly connected to the base 100. The transverse beam 220 is disposed between the two longitudinal beams 210 and extends along a second direction. The first direction is perpendicular to the second direction.

[0044] In this embodiment, the frame 200 forms a "U"-shaped structure through the combination of two longitudinal beams 210 and one transverse beam 220. This structure not only has excellent rigidity and stability, but also makes efficient use of space, making the entire device more compact.

[0045] like Figure 1-2 As shown, in some embodiments, the two longitudinal beams 210 are symmetrically arranged relative to the transverse beam 220. When the two longitudinal beams 210 are symmetrically arranged relative to the transverse beam 220, the supporting forces they exert on the transverse beam 220 are balanced on both sides. This balance helps reduce structural twisting or deformation caused by excessive force on one side, thereby improving the stability of the entire frame 200. In addition, the symmetrical layout also helps resist the effects of uneven external loads, making the frame 200 more uniform and stable under stress.

[0046] like Figure 1-2 As shown, in some embodiments, the crossbeam 220 is provided with a threaded through hole 221 extending along a first direction, and the lead screw 310 is threadedly connected to the threaded through hole 221.

[0047] In this embodiment, the inner wall of the threaded through hole is threaded to match the external thread of the lead screw 310, thus achieving a threaded connection. By rotating the lead screw 310, it can move linearly along a first direction within the threaded through hole 221. By adjusting the rotation direction and amount of the lead screw 310, the control force and precision during assembly and disassembly can be easily controlled, preventing damage to the assembled and disassembled components.

[0048] like Figure 1-2 As shown, in some embodiments, the assembly and disassembly device 1000 further includes an operating handle 400, which is connected to the end of the lead screw 310 away from the base 100. The operating handle 400 allows the user to easily grasp and rotate the lead screw 310 to apply a greater rotational torque, thereby more easily driving the lead screw 310 to disassemble the drive wheel assembly M via the female thread 320, reducing the user's physical exertion and improving work efficiency.

[0049] Although the present invention has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
