Movable-type hydraulic work protective platform in tunnel

Abstract

The invention relates to the technical field of civil engineering, and is specifically applied to a mobile hydraulic work protection platform in a tunnel, including a flatbed transport vehicle, a wheel-rail type hydraulic lifting platform part installed on the vehicle body, and a wheel-rail type hydraulic lifting arch installation trolley part It is the same as the wheel-rail hydraulic lifting and telescopic protection platform part. The wheel-rail hydraulic lifting platform part includes the wheel-rail hydraulic lifting platform, which includes the upper part of the platform and the lower part of the platform. The lower part of the platform is equipped with a platform walking device and a To support the supporting legs of the hydraulic lifting platform, the upper part of the platform is equipped with a lifting device and a foldable working platform. The installation trolley part of the wheel-rail hydraulic lifting arch frame includes the installation trolley installed on the trolley working platform, and the wheel-rail hydraulic lifting and telescopic The protective platform part includes a wheel-rail hydraulic lifting telescopic protective platform, a protective platform lifting device and a protective platform lifting platform. This platform has the technical advantage of high security in centralized operations.

Description

technical field [0001] The invention relates to the technical field of civil construction engineering, in particular to a mobile hydraulic work protection platform used in tunnels. Background technique [0002] With the continuous rapid development of my country's economy, the focus of the construction of high-speed railways and expressways is gradually tilted to the west, and the terrain and landforms of the mountains and valleys in the west make the proportion of tunnel construction more and more high, and some even exceed 80%. , especially long tunnels, high ground stress tunnels, soft rock tunnels and other unfavorable geological tunnels have many types, rapid changes, and difficult construction tasks. Tunnel engineering is often the control point of engineering construction projects. Layers, alteration zones, landslides, high ground stress, rockbursts, etc., are prone to landslides, falling blocks, surface subsidence, deformation, collapse, etc. The progress of the projec...

[0002] With the continuous rapid development of my country's economy, the focus of the construction of high-speed railways and expressways is gradually tilted to the west, and the terrain and landforms of the mountains and valleys in the west make the proportion of tunnel construction more and more high, and some even exceed 80%. , especially long tunnels, high ground stress tunnels, soft rock tunnels and other unfavorable geological tunnels have many types, rapid changes, and difficult construction tasks. Tunnel engineering is often the control point of engineering construction projects. Layers, alteration zones, landslides, high ground stress, rockbursts, etc., are prone to landslides, falling blocks, surface subsidence, deformation, collapse, etc. The progress of the project cannot meet the requirements and accidents are prone to occur. Many large and medium-sized construction enterprises in the western region In the past and under construction of railway and highway projects, the construction of tunnel projects often seriously lags behind the overall construction period, and accidents of personal injury and death are prone to occur. The construction units and construction units are miserable, and many large and medium-sized construction enterprises are also lost Reputation also loses high benefits

[0003] At present, a lot of advanced machiner
