Abstract

The invention provides a guiding device for inspection well optical cable traction and a using method thereof. The guiding device comprises a support rod; a clamping slot for clamping the wellheads ofinspection wells is formed in one end of the support rod; the other end of the support rod is connected and fixed with elastic rubber; and pulleys are rotatably arranged at two ends of the support rod, respectively. The guiding device and the using method thereof are used for overcoming the problems of optical damage and easy core breakage in the existing inspection well optical cable laying process, and belong to the field of optical cable laying.

Description

technical field [0001] The invention relates to a guiding device for pulling an optical cable in a manhole and a using method thereof, belonging to the field of cable laying. Background technique [0002] In the process of laying optical cables in the existing manholes, it is time-consuming and labor-intensive to use manpower to pull the cables. When using the optical cable traction machine, the pulling force of the optical cable traction machine is not easy to control, and the bending radius of the optical cable is too small. It is easy to increase the communication loss of the optical cable core, and even There is a risk of core breakage. Contents of the invention [0003] The invention provides a guiding device for pulling an optical cable in an inspection shaft and a using method thereof, so as to overcome the problems of optical cable loss, easy core breakage and the like existing in the laying process of the existing inspection shaft optical cable. [0004] In order...
