Abstract

The invention discloses a covering type cable bridge with a fire delaying function, belongs to the technical field of cable bridge equipment, and can play a role in preventing fire spreading to a certain extent through arrangement of a plurality of partition plates when a cable burns due to a fault, and meanwhile, high temperature generated during burning can fuse a trigger fuse rope, so that the cable can be prevented from being burnt, and the service life of the cable is prolonged. The arc-shaped cover plate and the counterweight pressing block fall off due to loss of support of the trigger melting rope, the combustion area of the cable is covered, the gravity of the counterweight pressing block can release the flame-retardant gas in the gas storage bag, the fire behavior is further delayed, in addition, the falling of the arc-shaped cover plate not only can trigger the buzzer to attract the attention of workers, but also can prevent the flame-retardant gas in the gas storage bag from falling off. And a coloring agent can be released into the purified water, so that the purified water changes color in a large area, the worker is helped to quickly observe the specific combustion area of the cable, and the maintenance efficiency of the worker is effectively improved.

Description

technical field [0001] The invention relates to the technical field of cable tray equipment, and more particularly, to a covered cable tray with a function of delaying fire. Background technique [0002] The cable tray is divided into trough type, tray type, ladder type, mesh type and other structures, which are composed of brackets, support arms and installation accessories. The bridge frame in the building can be erected independently, or it can be laid on various buildings (structures) and pipe gallery supports. It should reflect the characteristics of simple structure, beautiful appearance, flexible configuration and convenient maintenance. All parts need to be galvanized. , installed in the open air bridge outside the building. [0003] During the operation of the cable, the cable may burn due to short circuit, line overload, insulation breakdown, leakage, etc. However, the function of the existing cable tray is relatively single, and it only plays the role of anti-wi...
