Drainpipe optical cable mounting hardware and mounting method thereof

Abstract

The drainpipe optical cable installing metal tool and installing method provided by the invention relates to an installing device and an installing method for laying optical cable in city drainpipe (rain pipe, sewage pipe). The structure of the invention comprises a pre-twisted steel wire, steel wires, an adjustable pull rod, a hanging board, a bending limiting device; the adjustable pull rod is movably connected with the hanging board which is provided with a bottom board; the bottom board is provided with mounting holes and lifting eyes; the adjustable pull rod comprises a head, a sleeve; the two ends of the sleeve of the adjustable pull rod are respectively provided with a head; an adjusting screw on the head of the pull rod is matched with the adjusting screwed hole of the sleeve of the pull rod; a connecting buckle at one end of the steel wire is movable connected with a connecting cross of the adjustable pull rod through a pin; the other end of the steel wire is movably connected with a thimble through a pin; the pre-twisted steel wire is covered on the thimble; two clamping grooves are provided on the outer arc face of the bending limiting device; the two clamping grooves are respectively used to clamp the steel wire and the optical cable to ensure the bending radius of the optical cable.

Description

technical field [0001] The invention relates to a drainage pipe optical cable installation fitting and an installation method thereof, which relate to an installation device and an installation method for laying optical cables in urban drainage pipes (rainwater pipes, sewage pipes). Background technique [0002] With the rapid development of the communication industry, the existing urban pipeline resources are becoming increasingly scarce, and the increasingly strict municipal construction system has greatly increased the difficulty of the approval procedures for excavation and laying. However, the environmental conditions of laying optical cables in drainage pipes are relatively harsh, and due to the need for pipe dredging, hanging laying must be carried out, so higher requirements are put forward for the installation, corrosion resistance and strength performance of fittings, while the existing structure Ordinary goldware is still difficult to meet the above requirements. ...
