Supporting and guiding device for power lines for excavation devices

摘要

A supporting and guiding device for power lines 2 is intended for use in association with an excavation tool 15 mounted on a drilling machine 1. The device is formed by at least one supporting branch 4, having spacer elements 3, wherein a cable 16 is inserted into at least one housing in said spacer 3, and at least one supply hose 22 for the at least one line 2. The supply hose 22 contains hydraulic hoses and/or electric cables for signal transmission. The device includes transversal connection elements or cross members 42 which are adapted to support supply hoses 22 and are connected to the branch 4. Cable 16 of branch 4 runs through each spacer 3; also, the same cable 16 is subject to a preload generated by the insertion of at least one tensioning element.

1. A supporting and guiding device for power lines for use in association with an excavation tool mounted on a drilling machine; said supporting and guiding device being adapted for assuming a plurality of different operating configurations; said device comprising:
two supporting branches, each of the supporting branches including:
a plurality of, spacer elements, each of the spacer elements comprising at least two through holes;a cable or tension line inserted into said at least two through holes in said spacer elements;said power lines comprising at least one supply hose;at least one cross member, comprising at least one through housing for supporting the at least one supply hose, connected to said supporting branches;wherein each of said supporting branches comprises at least one tensioning element; andwherein the cable of each of the supporting branches passes through each of the spacer elements by passing through two of the through holes to form a closed path and the cable is subjected to a preload generated by insertion between two adjacent ones of the spacer elements of at least one tensioning element, the cable having a sufficient axial length such that all of the spacers crossed by said cable are kept in a state of contact with each other in all operating configurations.
