Description

Technical Field

[0001] The utility model relates to the technical field of subway engineering, in particular to an assembly operation platform for contact network pillars in an elevated section of a subway engineering. Background Art

[0002] The rapid growth of urban population is one of the main backgrounds for subway construction. With the acceleration of urbanization, the population is concentrated in the central area of ​​the city, and the traffic demand has increased greatly. Traditional modes of transportation can no longer meet the travel needs of urban residents. As an efficient, convenient and environmentally friendly mode of transportation, the subway can provide fast and large-capacity transportation and effectively alleviate the pressure of urban traffic. Environmental protection and sustainable development are one of the backgrounds for subway construction. Through underground or ground construction, subway projects reduce damage to the surface environment and reduce noise and air pollution. At the same time, the efficiency and large capacity of subway transportation methods are also conducive to reducing the use of private vehicles, alleviating traffic congestion and reducing exhaust emissions, and promoting sustainable urban development. Subway projects came into being under the background of urban transportation development. They have important functions such as promoting urban economic development, reducing environmental pollution, and enhancing the image of the city. They are an important part of the development of modern urban transportation.

[0003] However, the prior art of the overhead contact network support assembly platform for the elevated section of the subway project still has the following disadvantages:

[0004] 1. In the prior art, there is no support platform in the elevated section of the subway project, which is prone to danger when working. There are such disadvantages as safety risks: there is no support platform when working in the elevated section, and the workers need to stand or cross over to work at a height, which is in danger of falling. Especially in severe weather conditions, such as strong winds, rain and snow, the stability and safety of the workers are more easily affected. Inconvenience: without a support platform, when doing some work, such as positioning, fixing or installing equipment and materials, the workers may need to move or cross over operations, which increases the difficulty and inconvenience of the work. At the same time, it may also lead to reduced work efficiency and extended construction period. Equipment and material storage problems: without a support platform, it is impossible to provide a stable platform to place and store equipment and materials. This will increase the difficulty of operation for the staff, make it inconvenient to manage and use materials, and easily lead to the loss or cross contamination of equipment and materials. Difficulties in safety monitoring and emergency rescue: there is no support platform when working in the elevated section, which may bring difficulties to safety monitoring and emergency rescue. If there is no suitable platform for fast and stable operation when on-site monitoring or rescue is required, the emergency treatment effect may be affected. Utility Model Content
