For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] like Figures 1 to 5As shown, a fixed block 2 is installed on both sides of the bottom of the composite pipe body 1, a base 3 is arranged on the lower side of the fixed block 2, and a sliding seat 4 is installed on the upper surface of the base 3 through a longitudinal moving mechanism 8. The longitudinal moving mechanism 8 can drive the sliding seat 4 to move longitudinally and horizontally. Through the setting of the longitudinal moving mechanism 8, the position of the composite pipe body 1 can be longitudinally adjusted. A lifting seat 5 is arranged on the upper side of the sliding seat 4, and a lifting mechanism 13 that can drive the lifting seat 5 to lift vertically is arranged inside the sliding seat 4. Through the setting of the lifting mechanism 13, the position of the composite pipe body 1 can be adjusted in height.

[0023] The lower surface of the fixed block 2 is provided with two T-shaped slots 6 arranged in the transverse direction, and a T-shaped slider 7 is arranged inside the two T-shaped slots 6, and the bottoms of the two T-shaped sliders 7 are connected to the upper surface of the lifting seat 5. Through the arrangement of the T-shaped slots 6 and the T-shaped sliders 7, the position of the composite pipe body 1 can be adjusted transversely. Therefore, by adjusting the composite pipe body 1 transversely, longitudinally and in height, the composite pipe body 1 can be quickly and accurately docked with the main pipe, thereby improving the construction efficiency.

[0024] The upper surface of the T-shaped slider 7 is evenly installed with balls 23. The arrangement of the balls 23 can reduce the friction resistance between the T-shaped slider 7 and the T-shaped slot 6, making it easier and more labor-saving to push the composite pipe body 1 to move.

[0025] The longitudinal moving mechanism 8 includes a mounting groove 9 opened on the upper surface of the base 3, and a first threaded rod 10 is rotatably connected inside the mounting groove 9. A driving block 11 is installed on the outer surface of the first threaded rod 10, and the upper surface of the driving block 11 is connected to the lower surface of the sliding seat 4. The end of the first threaded rod 10 passes through the outside of the base 3 and is installed with a first hand wheel 12. When the longitudinal position of the composite pipe body 1 needs to be adjusted, the first hand wheel 12 can be rotated to drive the first threaded rod 10 to rotate, thereby driving the driving block 11 to slide along its surface. Through the connection between the sliding seat 4, the lifting seat 5 and the fixed block 2, the purpose of longitudinal movement of the composite pipe body 1 can be achieved.

[0026] The lifting mechanism 13 includes two slots 14 opened on the upper surface of the sliding seat 4, two insertion rods 15 are connected to the bottom of the lifting seat 5, and the insertion rods 15 are inserted in the slots 14, the sliding seat 4 is provided with an inner groove 16, and two second threaded rods 17 are vertically and rotatably installed inside the inner groove 16, and the two insertion rods 15 are provided with threaded holes 18 inside, and the two second threaded rods 17 are respectively threadedly connected with the two threaded holes 18, and the outer surfaces of the two second threaded rods 17 are installed with worm gears 19, and the inner groove 16 is rotatably connected with a rotating shaft 20, and the rotating shaft 20 is Two worms 21 are installed on the outer surface, and the two worms 21 are meshed with two worm wheels 19 respectively. The end of the rotating shaft 20 passes through the outer side of the lifting seat 5 and is installed with a second hand wheel 22. When the height of the composite pipe body 1 needs to be adjusted, the second hand wheel 22 can be turned to drive the rotating shaft 20 to rotate and drive the worm 21 to rotate. Since the worm 21 and the worm wheel 19 are meshed with each other, the second threaded rod 17 can be driven to rotate. When the second threaded rod 17 rotates, it can drive the insertion rod 15 to rise and fall, thereby achieving the purpose of adjusting the height of the composite pipe body 1. The inner walls on both sides of the slot 14 are provided with limit slots 24, and the outer surfaces on both sides of the insertion rod 15 are installed with limit blocks 25, and the limit blocks 25 are arranged in the limit slots 24.

[0028] The working principle of the utility model is as follows:

[0029] When docking the pipes, first use a crane to lift the composite pipe body 1 and place it directly at the docking point with the main pipe. At this time, there is a certain error between the composite pipe body 1 and the main pipe. The first hand wheel 12 can be turned to drive the first threaded rod 10 to rotate, and then drive the driving block 11 to slide along its surface. Through the connection between the sliding seat 4, the lifting seat 5 and the fixed block 2, the position of the composite pipe body 1 is longitudinally adjusted. The second hand wheel 22 is turned to drive the rotating shaft 20 to rotate, and the worm 21 is driven to rotate. Since the worm 21 and the worm wheel 19 are meshed with each other, the second threaded rod 17 can be driven to rotate. When the second threaded rod 17 rotates, it can drive the plug The rod 15 is raised and lowered to adjust the height of the position of the composite pipe body 1. During this process, the first hand wheel 12 and the second hand wheel 22 can rotate simultaneously, so as to improve the alignment speed. By adjusting the height and longitudinal position of the composite pipe body 1, the composite pipe body 1 and the main pipe are placed on the same axis. Then the composite pipe body 1 is pushed to move in the direction of the main pipe, and the distance between the composite pipe body 1 and the main pipe is adjusted. Then the welding operation can be carried out. Since the influence of wind on the lifting operation and the communication problems between the commander and the crane driver are avoided, the precise docking between the pipes can be completed quickly, thereby improving the construction efficiency of the heating project.
