Abstract

The invention discloses a temporary rapid installing support for cable erection. The temporary rapid installing support for cable erection comprises a square-arch-shaped frame body, inclined pull wires, ground anchors, hydraulic cylinders, a multi-way valve and a hydraulic station, wherein the inclined pull wires are connected with the top corners of the square-arch-shaped frame body and are fixed to the ground through the ground anchors, and the hydraulic cylinders are arranged between the inclined pull wires and the ground anchors 3 and are connected with the hydraulic station through the multi-way valve. The pull force of each pull wire can be independently controlled, it is only required that the pull wires and the ground anchors are connected together through the hydraulic cylinders and the hydraulic cylinders are controlled by the multi-way valve to stretch or contract to adjust the pull force of the pull wires, and the whole temporary rapid installing support for cable erection is easy, convenient and fast to install, high in corresponding speed and accurate in pull force control.

Description

technical field [0001] The invention relates to the field of cable bracket erection, in particular to a temporary quick installation bracket for cable erection. Background technique [0002] At present, temporary cables need to be erected in almost all construction sites. Temporary power cables are generally laid in two ways: buried or overhead. Due to the natural environment of the site, buried laying is not suitable for all situations, and The overhead cable laying method is favored by the majority of power companies due to its wide application range. The currently used aerial laying of cables is generally realized by setting up cable erection brackets, but the existing cable erection brackets are directly fixed on the ground through multiple cable-stayed wires and ground anchors. Loosening and offsetting the erection bracket, but these changes are difficult to be found, and there are serious safety hazards, and it takes a lot of time and manpower to adjust and fix the ca...
