Description

TECHNICAL FIELD

[0002] Polyethylene (PE) has excellent chemical properties, and PE pipes are made of high-crystallinity, non-polar thermoplastic resins. Polyethylene (PE) pipes are widely used in building water supply, building drainage, buried drainage pipes, building heating, gas transmission and distribution, gas transmission pipes and other fields due to their unique advantages. With the development of automation technology, pipe production lines are increasingly inclined to automation and intelligentization. As an important part of the automated production line, the clamping device can realize automatic feeding, conveying and processing of pipes, reduce the degree of manual intervention, and improve the stability and reliability of the production line.

[0003] The existing clamping device is difficult to select a suitable clamp according to the outer diameter of the pipe, which avoids the situation of unstable clamping caused by excessive mismatch between the clamp and the pipe, and limits the use scenarios of the clamp. Moreover, the clamping force distribution of some clamping devices is uneven, which may cause the clamping part to be concave inward to the PE pipe, resulting in damage to the PE pipe.

The cross beam is symmetrically installed with clamps on the lower surface, and the lower surface of the cross beam is symmetrically connected with first and second connecting rods through hinges. The polyethylene pipe lifting and clamping device is simple to operate. However, the chuck of the clamping device is fixed and cannot be adjusted or replaced according to the diameter of the pipe. Moreover, the distance between the chucks on both sides of the device cannot be adjusted, and the device is not suitable for pipes of different lengths, which limits the use scenarios of the clamping device and has certain technical defects.
