The second snap-fit ​​plate 17 is snapped into handwheel 13 through snap-fit ​​groove 16. A second spring 18 is fixed on both sides of one end of the second snap-fit ​​plate 17. Both second springs 18 are located inside fixing plate 11, and one end of both second springs 18 is fixed to fixing plate 11.

[0027] The auxiliary mechanism includes a third transmission rod 19, a fixed gear 20, a movable rack 21, a worm gear 22, a worm 23, a support plate 24, and a support rod 25. The third transmission rod 19 is rotatably connected to the inner side of the bottom end of one side of the first clamping plate 8.

The support rod 25 is fixed to one side of the top of the support plate 24. The support rod 25 is slidably connected to the first clamping plate 8.

[0028] Valve pipelines may be installed at different heights and positions. The auxiliary mechanism can ensure that the disassembly device can meet different height requirements, thereby stably supporting and fixing the valve pipeline, thus facilitating disassembly work. The design of the protection mechanism ensures that even if the handwheel 13 is accidentally touched after the pipeline is fixed, it will not affect the device's clamping and fixing of the valve pipeline, thus improving the safety of the device.

[0029] The process of using the pipe disassembly tool provided by this utility model is as follows: When the valve pipe is still a certain height above the ground, lift the device by pulling the handle 2 and move it so that the valve pipe is between the two second clamping plates 9. Rotate the worm 23. Since the worm 23 is meshed with the worm wheel 22, the rotation of the worm 23 drives the worm wheel 22 to rotate, which causes the third transmission rod 19, which is fixedly connected to the worm wheel 22, to rotate. Since the third transmission rod 19 is fixedly connected to the fixed gear 20, the rotation of the third transmission rod 19 drives the fixed gear 20 to rotate, which causes the moving rack 21, which is meshed with the fixed gear 20, to move. This causes the support plate 24, which is fixedly connected to the moving rack 21, to move, so that the bottom of the support plate 24 contacts the ground. At this time, the valve pipe is located between the two second clamping plates 9, and no manual lifting device is required.

[0030] Valves and pipelines may be installed at different heights and locations. The auxiliary mechanism can ensure that the disassembly device can meet different height requirements, thereby stably supporting and fixing the valves and pipelines, thus facilitating disassembly work.

[0031] At this time, turn the handwheel 13. The connecting rod 12, which slides with and is engaged with the handwheel 13, will also rotate. When the engagement groove 16 and the second engagement plate 17 are in opposite positions, press the handwheel 13 down. As the handwheel 13 moves, the first spring 15 inside the handwheel 13 will be compressed. As the handwheel 13 moves, it will engage with the fixed plate 11. During the movement of the handwheel 13, the bottom inclined surface of the handwheel 13 and the engagement groove 16 on the same side will contact the second engagement plate 17 and press the second engagement plate 17 to one end. This will compress the second spring 18, which is fixedly connected to the second engagement plate 17. As the handwheel 13 moves, it will engage with the fixed plate 11. At this time, the engagement groove 16 and the second engagement plate 17 are on the same horizontal plane. Under the push of the elastic force of the second spring 18, the second engagement plate 17 engages with the handwheel 13 through the engagement groove 16. At this time, the handwheel 13 is fixed inside the fixed plate 11.

[0032] At this time, turning the handwheel 13 causes the fixed plate 11 to rotate, which in turn causes the first transmission rod 3, which is fixedly connected to the fixed plate 11, to rotate as well. Since the first transmission rod 3 is fixedly connected to the first bevel gear 4, the rotation of the first bevel gear 4 causes the second bevel gear 5 to rotate, which in turn causes the second transmission rod 6, which is fixedly connected to the second bevel gear 5, to rotate. The rotation of the second transmission rod 6 causes the first threaded rod 7 to rotate. Since the threads of the two first threaded rods 7 have opposite directions, the two first clamping plates 8, which are threadedly connected to the first threaded rods 7, move closer to each other. When the first clamping plate 8 is about to approach the pipeline valve, the second clamping plate 9 is finely adjusted to clamp the pipeline valve by rotating the second threaded rod 10. At this time, the valve pipeline is fixed, which allows the worker to better disassemble and process the parts on the valve pipeline.

[0033] When the valve pipe is clamped, the second locking plate 17 is pulled to one end, so that the second locking plate 17 is no longer locked to the handwheel 13 through the locking groove 16. At this time, under the action of the spring force of the first spring 15, the handwheel 13 is no longer located inside the fixed plate 11. At this time, turning the handwheel 13 will only drive the connecting rod 12 fixed to the first locking plate 14 to rotate. Since the connecting rod 12 is rotatably connected to the fixed plate 11, the rotation of the handwheel 13 will not affect the rotation of the fixed plate 11. At this time, even if the handwheel 13 is accidentally touched, it will not affect the clamping of the valve pipe.

[0034] The present invention provides a pipe disassembly tool. Through the design of the transmission mechanism, even if the handwheel 13 is accidentally touched after the pipe is fixed, it will not affect the device's clamping and fixing of the valve pipe, thus improving the safety of the device. The valve pipe may be installed at different heights and positions. The auxiliary mechanism can ensure that the disassembly device can meet different height requirements, thereby stably supporting and fixing the valve pipe, thus facilitating the disassembly work.

[0035] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. It is understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of protection of the present invention is defined by the appended claims and their equivalents.
