A detachable special platform for the installation and maintenance of vault lighting fixtures in underground powerhouses of hydropower stations

Abstract

Provided is a detachable special platform for installation and overhaul of a vault illumination lamp of an underground powerhouse of a hydropower station. A platform board is arranged on a combined framework composed of an H-shaped framework body and a small rectangular framework body, the H-shaped framework body is composed of multiple main girders, the small rectangular framework body is defined by multiple auxiliary girders and main girders in an enclosed mode, the middle of the H-shaped framework body is provided with a cross beam, the bottoms of the four corners of the H-shaped framework body are provided with upright columns, the two ends of the platform board are provided with inclined short ladders, one side of the platform board is provided with an inclined long ladder, handrails are arranged on the periphery of the platform board, and doors are arranged on the positions, corresponding to the handrails, at the upper ends of the inclined short ladders and the upper end of the inclined long ladder respectively. According to the detachable special platform for installation and overhaul of the vault illumination lamp of the underground powerhouse of the hydropower station, the special platform assembled through the main girders, the auxiliary girders, the platform board, the handrails and the inclined ladders is installed on a bridge crane through upright columns, installation and overhaul personnel can install and overhaul the vault lamp of the powerhouse on the special platform. The platform is simple in structure and convenient to install and detach, improves work efficiency and reduces safety hidden hazards.

Description

technical field [0001] The invention relates to a special platform, in particular to a detachable special platform used for installation and maintenance of vaulted lighting lamps of an underground powerhouse of a hydropower station. Background technique [0002] The underground powerhouse of the hydropower station is located in the mountain and cannot obtain external natural light sources. Therefore, the lighting of the powerhouse is particularly important for the safe operation of the underground power station. At present, the vault lighting fixtures of underground workshops are mainly installed and overhauled by setting up temporary bent frames on the bridge machine. The installation and maintenance of lamps and lanterns by setting up temporary bent frames mainly have the following disadvantages: the materials for temporary bent frames are difficult to transport On the bridge crane, it is difficult to erect; erecting temporary bent frames is a high-altitude operation with ...

Problems solved by technology

At present, the vault lighting fixtures of underground workshops are mainly installed and overhauled by setting up temporary bent frames on the bridge machine. The installation and maintenance of lamps and lanterns by setting up temporary bent frames mainly have the following disadvantages: the materials for temporary bent frames are difficult to transport On the bridge crane, it is difficult to erect; erecting a temporary bent frame is a high-altitude operation with a high risk factor; the structural safety factor of the temporary bent frame itself is not high, and there are potential safety hazards
