[0027] In this embodiment, the inner wall of the limit block 10 is provided with an internal thread, and the external thread provided on the outer wall of the screw rod 8 matches the internal thread provided on the inner wall of the limit block 10 .

[0028] In this embodiment, the cross section of the limiting groove 5 is trapezoidal, and the limiting groove 5 and the limiting block 10 fit together.

[0029] In this embodiment, the stop plate 12 is in a rectangular block structure, and the outer wall of one side of the stop plate 12 is provided with concave and convex bodies at equal intervals.

[0030] Specific as Figure 1 , Figure 2 and Figure 4 As shown, when using this structure, start the servo motor 3, drive the first transmission wheel 6 to rotate through the servo motor 3, use the belt 7 to transmit the movement so that the second transmission wheel 13 and the first transmission wheel 6 rotate in the same direction and at the same speed, then use the first transmission wheel 6 and the second transmission wheel 13 to drive the screw rod 8 to rotate at the same time, and limit the fixing frame 9 through the limiting groove 5 and the limiting block 10, so that the fixing frame 9 moves up and down when the screw rod 8 rotates. This structure can adjust the pipe docking height, providing convenience for pipe construction.

[0031] Embodiment 2: A threaded hole is provided in the middle position of the fixing frame 9, and a handle 17 is movably installed on the fixing frame 9 through the threaded hole. A threaded rod 21 is provided on the outer wall of the handle 17, and the threaded rod 21 passes through the threaded hole and is movably connected with a connecting block 22. Upper pressure blocks 18 are symmetrically provided on the outer walls on both sides of the connecting block 22, and a transmission block 16 is provided on the outer wall of the upper pressure block 18. A clamping rod 14 is symmetrically and movably installed on the middle position of the fixing frame 9 through a bearing, and a sliding groove 15 is provided on the outer wall of the clamping rod 14. The outer wall of the clamping rod 14 is movably connected to the outer walls on both sides of the upper pressure block 18 through the sliding groove 15 and the transmission block 16.

[0032] In this embodiment, a threaded sleeve 19 is disposed at one end of the clamping rod 14 away from the fixing frame 9 , and a fixed threaded pin 20 is movably mounted on the sliding groove 15 through the threaded sleeve 19 .

[0035] Specific as Figure 1 , Figure 3 and Figure 5 As shown, when using this structure, the ports of the two pipes are respectively placed in the middle position of the clamping rod 14, and the handle 17 is rotated to drive the threaded rod 21 to rotate, so that the threaded rod 21 pushes the connecting block 22 to move downward, and the connecting block 22 pushes and drives the upper pressure block 18 to move downward and press against the outer wall above the pipe. Through the slide groove 15 and the transmission block 16, the clamping rod 14 moves with the upper pressure block 18 and rotates inward with one end as the axis to clamp the outer walls on both sides of the middle pipe, so that the clamping rod 14 and the upper pressure block 18 form a triangular clamping structure for the outer wall of the pipe, and the fixed threaded pin 20 is rotated to make the round convex body set at the front end of the fixed threaded pin 20 press against the outer walls on both sides of the pipe, and the pipe is clamped and fixed for the second time. This structure can provide stable clamping for pipes with different diameters.

[0036] Working principle: When in use, when splicing multiple sections of pipes, the device is moved to the working area through the universal wheel 4, and the electric cylinder 11 is started to make the stop plate 12 touch the ground. The convex body set on one side of the stop plate 12 increases the friction between the device and the ground to prevent the device from rolling. The ports of the two pipes are respectively placed in the middle position of the clamping rod 14, and the handle 17 is turned to drive the threaded rod 21 to rotate, so that the threaded rod 21 pushes the connecting block 22 to move downward, and the connecting block 22 pushes and drives the upper pressing block 18 to move downward and against the outer wall above the pipe. The clamping rod 14 moves with the upper pressing block 18 through the slide groove 15 and the transmission block 16, and rotates inward with one end as the axis to clamp the outer walls on both sides of the middle pipe, so that the clamping rod 14 and the upper pressing block 18 form a triangular clamp on the outer wall of the pipe. The holding structure is used to rotate the fixed threaded pin 20, and the convex body set at the front end of the fixed threaded pin 20 is pressed against the outer walls on both sides of the pipeline to perform secondary clamping and fixing of the pipeline. According to the height of the docking pipeline during use, the servo motor 3 is started, and the first transmission wheel 6 is driven to rotate by the servo motor 3. The second transmission wheel 13 and the first transmission wheel 6 are rotated in the same direction and at the same speed by the belt 7. Then the first transmission wheel 6 and the second transmission wheel 13 are used to drive the screw rod 8 to rotate at the same time. The fixing frame 9 is limited by the limiting groove 5 and the limiting block 10, so that the fixing frame 9 moves up and down when the screw rod 8 rotates, so as to adjust the entire pipeline docking height. The device can not only provide stable clamping docking according to different pipeline diameters, but also facilitate the adjustment of the pipeline docking height, thereby providing convenience for pipeline auxiliary positioning work.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
