Description

[0002] In various cable laying projects, especially when involving sheathed cable operation, auxiliary mechanisms are often needed to ensure the smooth progress of the tensioning process.

[0003] However, the existing tensioning auxiliary device still has some shortcomings in actual use: although the existing device can assist tensioning by rotating the rollers, the roller spacing is often fixed or has a very limited adjustment range. In actual application, the diameter of sheathed cable has diversity, and different engineering projects may use different specifications of cable. When facing cables with large diameter differences, the fixed spacing rollers cannot be effectively adapted. Excessive roller spacing may cause the cable to be unable to be stably supported between the rollers, and may easily shake, deviate or even come out of the rollers. Too small roller spacing cannot accommodate the cable, and forced passing may cause the rollers to excessively press the cable, which may also damage the cable sheath.
