Auxiliary protection device used for cable laying

The invention relates to an auxiliary protection device used for cable laying. The auxiliary protection device is characterized in that a rack comprises an angle plate (2), a hanging plate (2a) is arranged at one end of the angle plate (2), the two ends of the angle plate (2) are correspondingly connected with an upper supporting plate and a lower supporting plate (1 and 12), and each supporting plate is provided with at least two open sliding grooves (1a and 12a). Sliding trails (9) are arranged beside each open sliding groove (12a) of the lower supporting plate (12), and connected with a sliding angle support (10). Carrier rollers are connected to the corresponding open sliding grooves (1a and 12a) inside the upper supporting plate and the lower supporting plate (1 and 12), and each provided with at least one annular groove (5a). Locking assemblies are connected to the two supporting plates. By the adoption of the technical scheme, in the moving process of a cable, it is unnecessary to move the cable by people standing at the turning position of the cable, the labor cost is lowered, labor intensity is lowered, working efficiency is improved, and the cable is well protected.
