The base 1 is also provided with a lifting drive mechanism for driving the scissor frame 2 to extend and retract. Four sets of support blocks 3 are hinged to the top of the two sets of scissor frames 2 through hinges. A lifting platform 4 is slidably connected to the top of the four sets of support blocks 3. The scissor frames 2 are driven to extend and retract by the lifting drive mechanism, so that the lifting platform 4 rises and falls with the extension and retraction of the scissor frames 2.

[0022] A second groove 13 is provided on the right side of the top of the base 1. The side of the turning handle 10 close to the second groove 13 passes through the rotating shaft and penetrates into the second groove 13 and the first sprocket 14. There are two groups of first sprockets 14 and are symmetrically distributed in the second groove 13. One end of the bidirectional screw rod 11 close to the second groove 13 passes through the bearing and penetrates into the second groove 13 and is fixed with a second sprocket 15. The two groups of second sprockets 15 and the two groups of first sprockets 14 are respectively sleeved with chains and connected through chain transmission. The first sprocket 14 is driven to rotate by turning the turning handle 10, and the first sprocket 14 drives the second sprocket 15 to rotate through the chain, thereby realizing the rotation of the two groups of bidirectional screw rods 11.

[0023] A T-shaped slider 16 is welded and fixed on the top of the support block 3, and a T-shaped groove 17 adapted to the T-shaped slider 16 is opened at the bottom of the lifting platform 4. The T-shaped slider 16 is slidably arranged in the T-shaped groove 17, and the sliding connection between the support block 3 and the lifting platform 4 is realized through the cooperation of the T-shaped slider 16 and the T-shaped groove 17.

[0027] When it is necessary to carry out docking operation on adjacent pipes in the municipal heating project, the lifting platform 4 is first driven to lift above the base 1 by the lifting drive mechanism, and the support seat 5 at the top of the lifting platform 4 is adjusted to an appropriate height according to the actual installation height of the pipe to be docked, and then the pipe to be docked is placed in the pipe placement groove 6 at the top of the support seat 5. The placement method is selected according to the actual construction needs. It can be placed directly from top to bottom on the L-shaped support plate 7, or it can be placed horizontally between the front and rear groups of L-shaped support plates 7. After placement, the front and rear groups of pipe clamps 8 are driven by the clamping mechanism to move toward each other, and the pipe to be docked is clamped and fixed. Then, the two groups of support seats 5 at the top of the lifting platform 4 are driven to move toward each other by the horizontal driving mechanism until the two clamped and fixed pipes are driven to dock with each other, thus completing the auxiliary docking work of the pipes.
