A temporary support for cable erection with automatic adjustment function

Abstract

The invention relates to a temporary support for cable erection with the automatic adjustment function. The temporary support comprises a support body, a hydraulic system and a PLC control system. Stay cables are connected through the hydraulic system, so that the effects of linkage and joint adjustment are achieved. Tension of each stay cable can be independently and simultaneously controlled by the PLC control system. According to the temporary support, installation is simple and convenient, the stay cables are connected with ground anchors only through a hydraulic cylinder, tension of the stay cables is adjusted through the method that a hydraulic valve controls the hydraulic cylinder to stretch and contract, the response speed is high, tension is accurately controlled, and the whole device is installed rapidly and conveniently.

Description

technical field [0001] The invention relates to the field of cable support erection, in particular to a temporary support for cable erection with an automatic adjustment function. 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 ad...

Problems solved by technology

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 detect, posing serious safety hazards, and it takes a lot of time and manpower to adjust and fix the cable erection bracket during the erection process, which seriously affects the construction progress

[0003] During the construction of high-voltage transmission circuits, it is necessary to cross the transmission lines in use, railways, traffic arterial roads, etc., and to erect temporary arched frames. Due to the large span of the frames, many cable-stayed wires are required to fix them. To ensure safety, the number of cable-stayed wires Many, large tension; after the whole frame is assumed to be completed, the main diagonal stay wire needs to be tightened in the fixing stage. Now the chain is tightened by the reverse chain. The conventional reverse chain is too long, the tightening speed is slow, and the connecting hook It is quite bulky and inconvenient to use. The function of using custom-made uplink equipment is single and the utilization rate of equipment resources is low.

[0004] After the cable-stayed wires of the above-mentioned brackets are installed, there are few personnel to check and maintain them. They have no intuitive understanding of the status of the entire bracket. The staff do not know how much tension is required for each cable-stayed wire, which has buried the safety and stability of the brackets. safety hazard
