Cable laying manner to cable receiving tool, cable receiving tool device and cable receiving tool

摘要

PROBLEM TO BE SOLVED: To decrease cable drawing-in force, and to support and hold a cable surely after its drawing out, by installing supporting sub-girders between main girders by moving the sub-girders back downwards by specified distance from sub-girders with rollers at the time of drawing-in the cable, and by fitting cable supporting appliances onto the upper surfaces of the supporting sub-girders after its drawing-in. ;SOLUTION: A cable receiver 1 is composed of a pair of, right and left, main girders 2, a plurality of supporting sub-girders 3 installed at specified intervals in the direction of drawing in between the main girders 2, and a plurality of sub-girders 4 with rollers installed at the centers of the supporting sub-girders 3 between the main girders 2. And, when a cable W is drawn in, the supporting sub-girders 3 are installed between the main girders 2 moving back downwards so that its upper surface may be lower than that of the cable W on the sub-girders 4 with rollers by a difference of altitude H1. And cable supporting appliances 8 for supporting the cable W after its drawing in are fitted to the top surfaces of the supporting sub-girders 3. Accordingly, the cable W does not come into contact with the supporting sub-girders 3, and the cable W drawing-in force can be decreased at the time of its drawing in, since it is supported only by the sub-girders 4 with rollers.;COPYRIGHT: (C)1998,JPO
