[0052] The inner wall of the sliding rod 803 is slidably connected with a compression rod 901, one end of the compression rod 901 in the outside is fixedly connected with the extrusion seat 9, and the other end of the compression rod 901 in the inside of the sliding rod 803 is fixedly connected with a limiting seat 902, the end of the limiting seat 902 is fixedly connected with an extrusion spring 903, and the other end of the extrusion spring 903 is fixedly connected with the inner wall of the sliding rod 803, at this time, the displacement seat 802 pushes the sliding rod 803 to slide along the inner wall of the guide seat 804, and under the movement of the sliding rod 803, the extrusion seat 9 and the compression rod 901 are driven to move;

[0053] When the outer surface of the extrusion seat 9 is attached to the inner wall of the pipeline 10, at this time, the sliding rod 803 continues to move to extrude the extrusion seat 9 and the pipeline 10, so that the extrusion spring 903 slides along the outer surface of the compression rod 901, and the extrusion spring 903 is extruded between the limiting seat 902 and the sliding rod 803, and under the action of the plurality of extrusion seats 9, the position of the pipeline 10 is relatively stable;

[0054] At this time, the crane pulls the lifting lug 2, the moving seat 304 and the connecting rod 305 are pulled to move upward, the first connecting seat 5 moves upward, under the action of gravity, the rotating wall 501 rotates to drive the clamping wall 502 to rotate, at this time, the two clamping seats 503 are in contact with and extrude the outer surface of the pipeline 10 and clamp the pipeline 10, at this time, the pipeline 10 can be stably moved by the crane, and when being in a suitable position, the pipeline 10 is in a horizontal position, which is convenient for alignment with other pipelines 10.

[0055] At this time, the pipeline 10 is lowered to contact the placing rack, the contact seat 603 is not fixed relative to the first connecting seat 5 by rotating the fixing bolt 601, under the rebound of the extrusion spring 903, the sliding rod 803 is pushed to slide reversely, under the rebound of the stretching spring 705, the pushing rod 702 pushes the pushing seat 8 to move away from the second connecting seat 7;

[0056] At this time, the sliding rod 803 moves to separate the extrusion seat 9 and the pipeline 10, so that the pipeline 10 can be disassembled, at this time, the adjusting screw rod 301 is driven to rotate by the driving motor, so that the two first connecting seats 5 move reversely until the clamping wall 502 is separated from the pipeline 10, so that the pipeline 10 can be disassembled and placed, and the movement of the pipeline 10 is completed.

[0057] Working principle: when the pipeline 10 needs to be lifted, the length of the pipeline 10 is adjusted, at this time, the main bevel gear 401 is driven to rotate by starting the driving mechanism, under the rotation of the main bevel gear 401, the main bevel gear 401 drives the driven bevel gear 4 to rotate;

[0058] At this time, the bevel gear 4 rotates on the upper surface of the fixed seat 3, and under the rotation of the bevel gear 4, the adjusting screw rod 301 rotates along the inner wall of the bevel gear 4, driving the rotating seat 302 to move up and down;

[0059] Under the up-and-down movement of the rotating seat 302, the two rotating rods 303 are driven to move and rotate, and at this time, the rotating rods 303 push the moving seat 304 to move. Since the rotating angles of the two rotating rods 303 are the same, the two moving seats 304 are pushed to move the same distance, so that the pipeline 10 is in the center position of the two support frames 1, facilitating the stability during hoisting;

[0060] When the two moving seats 304 are moved to the appropriate position, the moving seat 304 moves to move the connecting rod 305, and at this time, the connecting rod 305 drives the first connecting seat 5 to be in the appropriate position;

[0064] Under the movement of the contact seat 603, the push rod 702 moves accordingly, and at this time, the push rod 702 slides along the inner wall of the second connecting seat 7, so that the tension spring 705 is stretched. When the contact seat 603 moves to the appropriate position, the two fixed bolts 601 are in close contact with the two sides of the first connecting seat 5 by rotating the fixed bolt 601, so that the position of the contact seat 603 is fixed relative to the first connecting seat 5;

[0065] When the pushing rod 702 moves, the pushing seat 8 moves, and the pushing seat 8 moves relative to the second connecting seat 7, and the displacement seat 802 moves under the movement of the pushing seat 8 and the rotation of the extrusion rod 801;

[0066] At this time, the displacement seat 802 pushes the sliding rod 803 to slide along the inner wall of the guide seat 804, and the sliding rod 803 drives the extrusion seat 9 and the compression rod 901 to move under the movement of the sliding rod 803;

[0067] When the outer surface of the extrusion seat 9 is attached to the inner wall of the pipe 10, the sliding rod 803 continues to move to extrude the extrusion seat 9 and the pipe 10, and the extrusion spring 903 slides along the outer surface of the compression rod 901, and the extrusion spring 903 is extruded between the limiting seat 902 and the sliding rod 803, and the position of the pipe 10 is relatively stable under the action of the plurality of extrusion seats 9;

[0068] At this time, the crane pulls the lifting lug 2, the moving seat 304 and the connecting rod 305 move upwards, and the first connecting seat 5 moves upwards, and the rotating wall 501 rotates under the action of gravity, and the clamping wall 502 rotates, and the two clamping seats 503 contact and extrude the outer surface of the pipe 10, and the pipe 10 is clamped, and at this time, the pipe 10 can be stably moved by the crane, and when it is in the appropriate position, the pipe 10 is in the horizontal position, which is convenient for alignment with other pipes 10.

[0069] At this time, the pipe 10 is lowered to contact the placing rack, the contact seat 603 is not fixed relative to the first connecting seat 5 by rotating the fixing bolt 601, the sliding rod 803 slides reversely under the rebound of the extrusion spring 903, and the pushing rod 702 pushes the pushing seat 8 away from the second connecting seat 7 under the rebound of the stretching spring 705;
