Cable-stayed suspension combined suspending method for cable protection in gallery inspection

Abstract

The invention provides a cable-stayed suspension combined suspending method for cable protection in gallery inspection, belonging to the technical fields of equipment inspection and overhaul. The suspending method mainly comprises the following steps of: machining lifting lugs, manufacturing and installing a tensile supporting frame, and fixing and suspending a chain block; releasing a cable, connecting and adjusting; and pulling the cable out of a bridge frame and restoring. In the invention, complex processes such as removing the used cable from an electricity utilization site, drawing out, putting in, wiring, checking and the like are avoided, influence from the used cable when a truss is removed is effectively overcome, hardly predicated hidden dangers appearing after the cable is cut off are avoided, the construction cost of an overhaul or technical modification project is reduced, the overhaul or technical modification construction period is shortened, and a new method for effectively solving the problem of overhaul or technical modification for an entire removing gallery overspan building in a plant area is provided. The method provided by the invention has the advantages of capability of operating in advance, safety and reliability, high overhaul work efficiency, high economic benefit and the like.

Description

technical field [0001] The invention belongs to the technical field of equipment detection and maintenance, and in particular relates to a cable-stayed-suspension combined hanging method for protecting cables in corridor maintenance. Background technique [0002] In the production process of chemical or metallurgical enterprises, it often happens that the belt corridor needs to be dismantled and rebuilt because the process cannot meet the production needs or the process is improved. There are often many cables passing through the corridor (laid in the cable bridge on the corridor). , sometimes the maintenance period is very tight. How to ensure that the cables are removed in a limited time so that the corridor structure can be hoisted and restored, the maintenance is difficult. Usually there are two solutions: one is to remove all the routing marks of each cable Withdrawn, and after the renovation of the corridor is completed, it will be worn back and restored. If the corri...

AI Technical Summary

Problems solved by technology

If the corridor involves many cables and long paths, and the cables are in the bridge frame outside the corridor, it is difficult to withdraw and recover high-altitude operations, and the risk factor is relatively high. In addition, in this scheme, the hoisting operation of the corridor must be staggered from the electrical professional work, resulting in construction period Delay; another solution is to cut all the cables passing through the corridor and add a terminal box transition

Since the corridors are mostly open-air structures, and there are many types of cables, cutting the cables will definitely leave many unpredictable hidden dangers for future production
