Technical Field
The invention relates to the technical field of optical cable installation, in particular to an anti-blocking end head traction device for optical cable laying work.
Background
Fiber optic cables are manufactured to meet optical, mechanical, or environmental performance specifications and utilize one or more optical fibers disposed in a covering jacket as the transmission medium and may be used individually or in groups as telecommunication cable assemblies. The optical cable is mainly composed of optical fibers, a plastic protective sleeve and a plastic outer skin, and metals such as gold, silver, copper and aluminum are not contained in the optical cable, so that the optical cable generally has no recycling value. The optical cable is a communication line which is formed by a certain number of optical fibers forming a cable core according to a certain mode, is externally coated with a sheath, and is also coated with an outer protective layer for realizing optical signal transmission. Namely: a cable is formed by subjecting an optical fiber to a certain process. The basic structure of the optical cable generally comprises a cable core, a reinforcing steel wire, a filler, a sheath and other parts, and further comprises a waterproof layer, a buffer layer, an insulated metal wire and other components according to requirements.
The optical cable is at the laying process, need pull the optical cable, make it pass through long pipeline, the optical cable is in the later stage of pulling, because many optical cables have in the pipeline, the optical cable is single independent traction, there is the clearance between the adjacent optical cable, lead to the very easy jam of the optical cable of back traction to the clearance, frictional force between the optical cable has been increased, the resistance of optical cable tractive in-process has been improved, make the easy mutual extrusion between the optical cable lead to the problem of deformation, and lead to easily dragging being obstructed or the failure of process, for this reason, we provide an optical cable laying work and prevent the end tractive device of jam.
