[0023] The inventor of this solution found that in the prior art, when a worker replaces a jumper pipe, he first uses a pipe buckle to loosen the joint, holds the jumper pipe with one hand, and uses the other hand to rotate the joint counterclockwise. Two workers are required to coordinate to disassemble the two ends of the jumper pipe and then lift it to the designated location. If the two workers do not coordinate well, it is easy for the pipe to fall and hit someone, and the work efficiency is not high. This embodiment provides the following solution:

[0024] like Figure 1-2 As shown, this embodiment provides a clamping device for disassembling and assembling pipes, including a workbench 1, a lower rotating fixed arm 2 and an upper rotating fixed arm 3, one end of the lower rotating fixed arm 2 can be rotatably connected to the workbench 1, the upper rotating fixed arm 3 can be rotatably connected to the other end of the lower rotating fixed arm 2, and one end of the upper rotating fixed arm 3 is connected to a clamping member 4.

[0025] It should be noted that the clamping member 4 is adjusted to the pipe disassembly position after being rotated by the lower rotating fixed arm 2 and the upper rotating fixed arm 3. The practical clamping member 4 is used to clamp and fix the pipe to be disassembled, thereby facilitating the disassembly and assembly operation for the operator.

[0026] Specifically, the workbench 1 is provided with a lower rotating transmission device 5, the output end of the lower rotating transmission device 5 is connected to one end of the lower rotating fixed arm 2, and the other end of the lower rotating fixed arm 2 is provided with an upper rotating transmission device 6, and the output end of the upper rotating transmission device 6 is connected to the upper rotating fixed arm 3. It should be noted that both the lower rotating transmission device 5 and the upper rotating transmission device 6 adopt a hand-cranked reducer, so that the cost can be further reduced. The hand-cranked reducer includes a reducer, a brake and a handwheel, the brake is connected to the input end of the reducer, and the handwheel is connected to the brake. The handwheel serves as a power input, and the handwheel is rotated to output the power of the reducer. The position of the reducer can be positioned and fixed by the brake. The lower rotating transmission device 5 and the upper rotating transmission device 6 are operated by the operator to rotate the lower rotating fixed arm 2 and the upper rotating fixed arm 3 to a suitable position and are positioned and fixed by the brake.

[0027] Specifically, the clamping member 4 also includes a support plate 44, a rotating disk 45, a screw rod 46, and a connecting block 47 connected to the lower claw 41. The support plate 44 is provided with a nut 441, and the upper claw 42 is connected to the third rotating shaft 421; the screw rod 46 is cooperatively connected to the nut 441, one end of the screw rod 46 is fixed to the rotating disk 45, and the other end of the screw rod 46 can be movably connected to the connecting block 47, and the connecting block 47 can be rotatably connected to the third rotating shaft 421.

[0028] One end of the connecting block 47 is provided with a connecting portion 471, on which a first rolling groove is provided, in which a spherical rolling member 48 is provided, and the spherical rolling member 48 is made of a steel ball. The screw rod 46 includes a rolling portion 461 and a connecting member 462, the rolling portion 461 is provided at the other end of the screw rod 46, and a second rolling groove matching the spherical rolling member 48 is provided on the rolling portion 461. The connecting member 462 is sleeved on the other end of the screw rod 46, the outer diameter of the rolling portion 461 is larger than the diameter of the sleeve hole of the connecting member 462, the diameter of the sleeve hole of the connecting member 462 is larger than the diameter of the screw rod 46, and the connecting member 462 is connected to the connecting portion 471.

[0029] It should be noted that the connection part 471 is provided with an external thread on the outside, and the connection piece 462 is provided with an internal thread matching the external thread. The connection piece 462 is fixed on the connection part 471 by matching the external thread with the internal thread. After the connection part 471 is fixed, a cavity is formed between the connection part 471 and the connection piece 462, so that the rolling part 461 can move in the cavity or the first rolling groove or move through the spherical rolling part 48. In addition, the diameter of the sleeve hole of the connection piece 462 is larger than the diameter of the screw rod 46, so that the screw rod 46 will not interfere when moving. Since the outer diameter of the rolling part 461 is larger than the diameter of the sleeve hole of the connection piece 462, the rolling part 461 will not move out of the connection piece 462.

[0030] When the operator rotates the rotating disk 45 , the screw rod 46 moves up and down in the nut 441 , thereby pushing or stretching the third rotating shaft 421 . During this process, the screw rod 46 will not be interfered with, so that the upper claw 42 rotates to open and close.

[0031] Further, the clamping member 4 is rotatably connected to one end of the upper rotating fixed arm 3. Specifically, the clamping member 4 is connected to a rotating seat 7, and the rotating seat 7 is rotatably connected to one end of the upper rotating fixed arm 3 through a first rotating shaft 71. The first rotating shaft 71 is a screw rod, and the first rotating shaft 71 passes through the extended end of the upper rotating fixed arm 3 and is provided with a rotating fixed member 72. It should be noted that an internal thread that is connected to the first rotating shaft 71 is provided in the rotating fixed member 72. When the position of the clamping member 4 needs to be adjusted, the rotating fixed member 72 is loosened, and the clamping member 4 is rotated to the required position and then the rotating fixed member 72 is tightened.

[0032] Furthermore, a plurality of universal wheels 11 and directional wheels 12 are respectively provided on both sides of the bottom of the workbench 1. It should be noted that the universal wheels 11 can be used to adjust the direction, so that the workbench 1 can be conveniently moved to various directions, and the clamped pipe can be transported to any designated position.

[0033] During the specific implementation, the operator moves the workbench 1 to the position where the pipe needs to be disassembled and assembled, adjusts and rotates the lower rotating fixed arm 2, the upper rotating fixed arm 3 and the clamping member 4 to a position suitable for clamping the pipe, rotates the rotating disk 45 to rotate the upper claw 42 open, so that the pipe enters between the lower claw 41 and the upper claw 42, and then rotates the rotating disk 45 to rotate the upper claw 42 closed to clamp and fix the pipe before performing the disassembly and assembly operation.

[0034] In summary, the embodiments of the utility model provide a clamping device for disassembling and assembling pipes, which replaces the manual disassembly of the jumper pipe. A single person can disassemble the joints at both ends of the jumper pipe, and transport the jumper pipe to a designated location for placement through a rotating transmission device, thereby greatly improving personnel utilization, convenience and work safety.
