Clamping test bench of tunnel protective door, and wind pressure testing system comprising clamping test bench

Abstract

The invention discloses a clamping test bench of a tunnel protective door, and a wind pressure testing system comprising the clamping test bench, and belongs to the technical field of tunnel protective door detection. By arranging a test bench body and a test bench sliding cover which can be correspondingly matched, a protective door assembly is stably clamped in the clamping test bench effectively, and by arranging assemblies such as an air source generation device, an air storage tank and a three-position and four-way magnetic exchange valve corresponding to the clamping test bench, a wind pressure test of the tunnel protective door is effectively achieved. According to the clamping test bench and the wind pressure testing system comprising the same, the structure is simple, control is easy and convenient, the state of the tunnel protective door affected by piston wind in a tunnel can be effectively simulated, selectivity of the testing scheme is high, the accuracy of a testing result is high, a basis can be provided for the structural design and matched mounting of the tunnel protective door, safety and reliability of application of the tunnel protective door are improved, the application cost of the tunnel protective door is lowered, and great application and promotion value is achieved.

Description

technical field [0001] The invention belongs to the technical field of tunnel protective door detection, and in particular relates to a clamping test bench for a tunnel protective door and a wind pressure test system comprising it. Background technique [0002] In recent years, the rapid development of my country's railway construction has continuously shortened the "time distance" between various regions. As the speed of railway traffic increases, the requirements for infrastructure construction standards also increase. As an important part of railway infrastructure, railway tunnels play a very important role in the process of railway lines crossing natural elevation obstacles or plane obstacles. [0003] According to the different application environments and requirements of railway tunnels, their setting forms are also different, such as single-hole single-track tunnel, double-hole single-track tunnel, single-hole double-track tunnel, etc. In a railway tunnel, when a tra...

AI Technical Summary

Problems solved by technology

In the structural performance test of the tunnel protective door, the wind pressure test is an important test that the tunnel protective door needs to carry out. The test results can often reflect the application state and life cycle of the tunnel protective door under the action of piston wind. The structure and layout design of the door has excellent guiding significance; at present, the wind pressure test of the protective door of the tunnel can basically only rely on the field test, which not only has certain potential safety hazards, but also the test sample size is small and the test conditions are relatively simple , it is difficult to apply the test results by analogy, and there are large limitations, which restrict the safe application of tunnel protective doors
