AI Technical Summary
In existing technologies, when pulling cables, applying force to a single endpoint leads to concentrated traction force, which is difficult to control precisely. This can easily cause excessive local stress on the cable and damage it. Furthermore, the lack of a multi-point force application design to distribute the traction force affects construction efficiency and quality.
Design a cable traction device that includes a pulling mechanism and an adjusting mechanism. The traction shaft is driven to rotate by a motor, which drives multiple traction blocks to apply a uniform traction force to the cable. The position of the traction wheel is adjusted by a hydraulic telescopic cylinder to achieve multi-point force application and path adaptive guidance, thereby reducing friction and uneven force distribution.
It effectively disperses the traction force, reduces the risk of cable wear, ensures sufficient traction force and balanced cable stress, and improves construction efficiency and quality.
