[0029] As Figures 1-4 shown.

[0030] Working principle: Push the fixed seat 1 to move to the pipe docking place in cooperation with the moving wheels 2 installed on its bottom surface. The hydraulic cylinder 302 pushes the support column 303 to drive the support base 304 to descend, supporting the fixed seat 1 away from the bottom surface and maintaining stable horizontal support. Place the pipe to be docked on the upper surface of the concave plate 321. Rotate the connecting rods 323 on both sides to drive the threaded rod 322 to rotate and move towards the inside of the concave plate 321. When the threaded rod 322 rotates, the circular block 324 and the arc-shaped clamping plate 325 movably connected to one end of the threaded rod 322 will not rotate along with the threaded rod 322. When the threaded rod 322 moves, the inner wall of the arc-shaped clamping plate 325 contacts the outer surface of the pipe and fixes and clamps it. Start the power supply of the first drive motor 306 to make the first drive motor 306 drive the threaded columns with opposite threads at both ends in the transmission member 307 to rotate, so that the moving blocks engaged on the outer surface of the threaded columns move towards each other to drive the baffle 308 to move, causing the rotating shaft 309 installed on the side of the baffle 308 to rotate, thereby driving the inclined connecting column 310 to rotate and lift the height of the square plate 311. The rising of the square plate 311 drives the connecting block 312 to move and be limited on the outer surface of the limiting column 314 to keep the movement stable. After the square plate 311 moves to an appropriate height, start the power supply of the second drive motor 316 according to the angle of the docking pipe, so that the second drive motor 316 drives the transmission shaft 317 to rotate, thereby driving the first gear 318 to rotate. Through meshing, the second gear 320 is driven to rotate, thereby driving the concave plate 321 to swing and adjust the angle of the clamped pipe to assist in docking the docking pipe.
