Cable duct penetrating device

Abstract

The invention relates to a cable laying construction device, in particular to a cable duct penetrating device. The space inside a cable duct is limited, and the novel cable duct penetrating traditional construction mode is low in efficiency, high in difficulty and likely to damage an old cable. According to the technical scheme, the device comprises two sets of outside pipe pulley supporting pieces, a threading pipe, at least two inside pipe pulleys, a traction rope and a cone cover; the threading pipe is formed by connecting multiple monomer sleeves, and in the working state, the two sets ofoutside pipe pulley supporting pieces are located above the two ends of the threading pipe; clamping bases at the two ends of the threading pipe are each fixedly provided with one inside pipe pulley through a support in a clamped mode; the traction rope penetrates through the threading pipe to wind around the inside pipe pulleys and the two sets of outside pipe pulley supporting pieces in sequenceto form annular connection; the cone cover is detachably installed at one end of the threading pipe. The device is simple in structure, convenient to disassemble and assemble, convenient to use and carry, and capable of enabling multiple cables to penetrate through the cable duct at a time, lowering construction difficulty and labor intensity, improving the working efficiency and avoiding the phenomenon that an old cable is damaged in the threading process.

Description

technical field [0001] The invention relates to cable laying construction equipment, in particular to a cable trenching device. Background technique [0002] The cable trench is an underground pipeline for laying power cable facilities. The substations and voltage levels are different. After years of operation and line transformation, new and old cables are mixed in the cable trench. The space in the ditch is limited, and the old cables are laid out, which brings great troubles to the work of new cables passing through the ditch during the equipment transformation process; the conventional method is to use iron wires, insulating rods, etc. to force the new cables into the In the ditch, this operation method has the following defects: (1) the work efficiency is low, time-consuming and labor-intensive, and labor-intensive; Cable knotting phenomenon; (3) Both ends of the cable trench are located in the shaft, so long rods cannot be used for operation, making the construction e...

[0002] The cable trench is an underground pipeline for laying power cable facilities. The substations and voltage levels are different. After years of operation and line transformation, new and old cables are mixed in the cable trench. The space in the ditch is limited, and the old cables are laid out, which brings great troubles to the work of new cables passing through the ditch during the equipment transformation process; the conventional method is to use iron wires, insulating rods, etc. to force the new cables into the In the ditch, this operation method has the following defects: (1) the work efficiency is low, time-consuming and labor-intensive, and labor-intensive; Cable knotting phenomenon; (3) Both ends of the cable trench are located in the shaft, so long rods cannot be used for operation, making the construction extremely passive; (4) Iron wires or insulating rods are easy to scratch the existing cable insulation layer, causing damage to the old cable insulation , creating a safety hazard

(5) Mutual friction between old and new cables causes damage to the insulation layer
