Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-5 This utility model provides a technical solution:

[0028] A hoisting device for downhole workover tools includes:

[0029] Toolbox 1, with a lid 2 rotatably connected to one end of toolbox 1. Toolbox 1 and lid 2 are connected at the other end by a locking assembly, which includes a second return spring 14 and a locking block 15. Lid 2 is provided with a connecting block 16. Toolbox 1 is provided with a connecting groove 28 for locking the connecting block 16. Toolbox 1 is provided with a first mounting groove 17 for mounting the second return spring 14. The other end of the second return spring 14 is connected to the locking block 15. The connecting block 16 is provided with a locking groove 18 for locking the locking block 15. One end of the locking block 15 is provided with a limiting plate 19, which is connected between the locking block 15 and the second return spring 14. The limiting plate 19 can limit the locking block 15 and prevent the locking block 15 from moving out of the first mounting groove 17.

[0030] After placing the tools into the toolbox 1, the lid 2 is fastened onto the toolbox 1. The connecting block 16 on the lid 2 engages with the connecting groove 28 on the toolbox 1. During connection, one end of the connecting block 16 is arc-shaped, which can press the engaging block 15 to move. When the connecting block 16 is fully engaged in the connecting groove 28, the second return spring 14 releases its elastic potential energy, pushing one end of the engaging block 15 into the engaging groove 18, thus fixing the connecting block 16 in the connecting groove 28 and fixing the lid 2 to the upper end of the toolbox 1.

[0031] When opening the lid 2 to take out the tool, press the locking block 15 to push the locking block 15 out of the locking groove 18, and then lift one end of the lid 2.

[0032] A hanging ring 3 is fixedly provided on the lid 2. A hook 4 is connected to the hanging ring 3. A connecting plate 5 is provided on the hook 4. A first return spring 6 is provided on the connecting plate 5. A movable frame 7 is connected to the other end of the first return spring 6. A slot 8 is opened on the hook 4. The other end of the movable frame 7 is engaged in the slot 8. A telescopic rod 13 is provided between the movable frame 7 and the connecting plate 5. The first return spring 6 is sleeved on the outside of the telescopic rod 13.

[0033] When connecting the toolbox 1 to the hoisting device, push the movable frame 7 on the hook 4 to connect the hook 4 to the hanging ring 3. Then release the movable frame 7. The first return spring 6 releases its elastic potential energy to push the movable frame 7 to move, so that one end of the movable frame 7 is engaged in the slot 8 on the hook 4. The movable frame 7 can block the opening of the hook 4, which can effectively prevent the toolbox 1 from falling off accidentally due to various reasons during the hoisting process and reduce safety hazards.

[0034] The telescopic rod 13 can limit the movement path of the moving frame 7 when it moves, and reduce the deformation of the first return spring 6.

[0035] Furthermore, there are four hanging rings 3 and four hooks 4. The hanging rings 3 are located at the four corners of the box cover 2, which can improve the balance of the toolbox 1 during lifting and thus improve the safety of lifting.

[0036] A threaded rod 9 is threadedly connected to the box cover 2. One end of the threaded rod 9 is rotatably connected to a clamping plate 10, and the other end of the threaded rod 9 is provided with a handle 11.

[0037] When clamping and fixing the tools in the toolbox 1, turn the handle 11, the threaded rod 9 drives the clamping plate 10 to move, the clamping plate 10 clamps the tools, the threaded rod 9 can adjust the movement of the clamping plate 10 to clamp and fix the tools, the clamping plate 10 can reduce the shaking of the tools in the toolbox 1, reduce the difficulty and risk of operation caused by tool shaking or tilting, and improve the safety and stability of the operation.

[0038] The lower end of the toolbox 1 is provided with a buffer assembly, which includes a buffer spring 22, a connecting rod 23 and a moving part 24. One end of the connecting rod 23 is fixedly connected to the toolbox 1. The moving part 24 has a second mounting groove 25 for installing the buffer spring 22. The other end of the connecting rod 23 is connected to the other end of the buffer spring 22. A through hole 26 is provided on one side of the second mounting groove 25. A damper 27 is sleeved inside the buffer spring 22. The two ends of the damper 27 are respectively connected to the moving part 24 and the connecting rod 23. The end of the buffer assembly away from the toolbox 1 is provided with a self-locking universal wheel 12.

[0039] The self-locking caster wheel 12 facilitates the movement of the toolbox 1. When the toolbox 1 vibrates during movement, the connecting rod 23 compresses the damper 27 for cushioning. The buffer spring 22 and the damper 27 can cushion the connecting rod 23, reducing collisions between tools during movement and increasing tool life.

[0040] Furthermore, the clamping plate 10 is provided with a first rubber layer 20, and the toolbox 1 is provided with a second rubber layer 21.

[0041] By setting the first rubber layer 20 and the second rubber layer 21, the wear on the tool can be reduced and the tool's service life can be improved when the tool is placed and clamped.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
