Embodiment Construction

[0025] Specific embodiments according to the present invention are described in detail below.

[0026] On the basis of careful consideration, the present invention achieves: when a belt follows the guide pulley, a stable attitude of the belt in operation can be obtained, and thus a power distribution conductor can be pulled reliably.

[0027] The construction method for laying cables according to the present invention includes the steps of: placing an endless laying belt along a cable laying route; connecting cables to a given point of the laying belt; running the laying belt to lay cables along the cable laying route. Here, a construction method may include the following steps: longitudinally placing a plurality of endless laying belts along the cable laying route; Detach from the laying belt; send out the removed cable again; connect the cable to the starting point side of the second laying belt after the cable leaves the first laying belt and arrive at the starting point si...

Abstract

The present invention aims at laying cable conveniently and correctly. In the cable laying device, a laying belt is tensed by a guide pulley. One cable connector provided on the surface of the laying belt connects one end of cable to the laying belt. One driver and one tensor provided to the laying belt drives the laying belt and absorb its flexure. It the cable laying device,tension of the distributed cable on the laying belt makes the laying belt always contact with the guide pulley in the unchanged attitude without rotation.

Description

technical field [0001] The present invention relates to a construction method for laying cables and a cable laying device, in particular to a construction method for laying cables along a cable laying route in a structure and a cable laying device. Background technique [0002] Generally, a boiler room or the like in a thermal power plant requires a plurality of power distribution cables to be connected between a power room at ground level and control panels or electrical machinery and devices installed on the boiler room. In order to lay the distribution cables in the distribution pipes built in the boiler room, two methods are used: one method is to lift a cable reel with the distribution cables on the boiler room, and then place the distribution cables One end is fed downward from the top open end of the distribution pipe; the other method is to insert one end of the distribution cable into the distribution pipe from the bottom open end of the distribution pipe, and then ...
