Fixing device for fire-fighting smoke exhaust pipe gallery

Abstract

The invention discloses a fixing device for a fire-fighting smoke exhaust pipe gallery. The fixing device comprises a connecting mechanism, a rubber cushion block is fixedly installed on the surface of one side of the connecting mechanism, a clamping mechanism is fixedly connected to the lower end of the connecting mechanism, a fixing frame body is fixedly installed on the surface of the other side of the connecting mechanism, and the upper surface of the fixing frame body is fixedly connected with a rubber strap; and the connecting mechanism comprises a connecting vertical rod, a movable sliding groove, a return spring, a movable sliding block, a supporting sliding column, an upper fixing bayonet, a movable sliding way, a movable sliding hole, a fixing bayonet and a plastic sheath, and the position, close to the upper end, in the connecting vertical rod is provided with the movable sliding groove. According to the fixing device for the fire-fighting smoke exhaust pipe gallery, mounting and fixing of the connecting mechanism can be rapidly completed, mounting is quite easy, fixing through tools and screws is not needed and is not tedious, the height of a pipeline can be conveniently adjusted, and therefore the fixing device is suitable for various mounting environments and mounting requirements.

Description

technical field [0001] The invention relates to the field of fixing devices, in particular to a fixing device for a fire-fighting smoke exhaust pipe gallery. Background technique [0002] Underground pipelines are an important part of urban infrastructure, including pipelines for water supply, drainage, gas, electricity, telecommunications, heating, and industry. The "lifeline" of the urban comprehensive utility corridor refers to the collection of various public pipelines installed on the ground, underground or overhead in an overall tunnel structure, and the intensification of various pipelines related to municipal power communication, thermal water supply and drainage, etc. It is installed in the underground space and is managed by a special safety monitoring system. Among them, the fire smoke exhaust pipe is also one of the main pipes. It is mainly used for fire smoke exhaust. In the event of a fire, it can discharge a large amount of toxic smoke from the fire scene , w...

Problems solved by technology

[0003] However, the existing fixing devices for fire-fighting and smoke exhaust pipe gallery have certain disadvantages in use. In use and installation, the connection mechanism is generally fixed and installed on the side wall of the pipe gallery with expansion screws, which is easy to damage the side wall structure during installation. And it is very troublesome to install, and it is not easy to disassemble and maintain or replace later, and the height of the fixing frame is fixed, and its height cannot be adjusted to adapt to various installation environments, and it cannot be disassembled, so the overall volume is large and cannot be conveniently installed. carry and store
