Description

Technical Field

[0001] This utility model relates to the field of pipe assembly technology, specifically a clamp for pipe assembly and alignment. Background Technology

[0002] Pipelines are used in all aspects of people's daily lives. Pipelines can play a role in fluid transportation, material transfer, energy transmission and isolation protection. In order to extend the transportation distance, pipelines need to be assembled. Pipeline assembly requires clamps for pipe assembly and alignment.

[0003] Existing clamps for pipe assembly and alignment typically only clamp pipes of a fixed size. After clamping and fixing, the two pipes are aligned and fitted together before assembly can begin.

[0004] Existing clamps for pipe assembly and alignment have the following problems: the clamps cannot adapt to pipes of different diameters, and workers need to change different clamps for pipes of different diameters, which reduces work efficiency. Therefore, we propose a clamp for pipe assembly and alignment. Utility Model Content

[0023] The working principle of the clamp for pipe assembly provided by this utility model is as follows: When pipe assembly is required, the worker first opens the protective door 14 through the handle 16, then places one end of each of the two pipes onto the outside of the contact plates 312 on both sides. Then, the microcontroller 4 controls the motor 5 to start. The output shaft of the motor 5 drives the lead screw 302 to rotate. Under the action of the limit block 304 and the slot 305, the sliding seats 303 on both sides move away from each other. Under the action of the connecting rod 307 and the second connecting rod 309, the movement of the sliding seat 303 is driven by the second connecting rod 309 to the contact plate 312. Plate 312 moves away from the center of sliding seat 303 until it contacts the inner wall of the pipe, thus securing the pipe in place. Then, linear motor 7 is turned on, and it drives the two pipes to move back and forth via movable seat 8. Motor 13 is turned on, and its output shaft drives lead screw 9 to rotate. The rotation of lead screw 9 causes the two pipes to move left and right via slider 10. Electric telescopic rod 11 is turned on, and its telescopic shaft drives the two pipes to move up and down until the ends of the two pipes that are close to each other are aligned. After that, the assembly of the two pipes can be carried out.
