Movable-type hydraulic work protective platform in tunnel

Abstract

The invention relates to the technical field of civil engineering, in particular to a movable-type hydraulic work protective platform applied into a tunnel. The movable-type hydraulic work protectiveplatform comprises a flat transporting trolley, a wheeltrack-type hydraulic lifting rack part mounted on a trolley body, a wheeltrack-type hydraulic lifting arching mounting trolley part and a wheeltrack-type hydraulic lifting telescopic protective rack part. The wheeltrack-type hydraulic lifting rack part comprises a wheeltrack-type hydraulic lifting rack which comprises a rack upper part and a rack lower part. The rack lower part is provided with a rack travelling device and supporting legs for supporting the hydraulic lifting rack, and the rack upper part is provided with a lifting device and a foldable working platform. The wheeltrack-type hydraulic lifting arching mounting trolley part comprises a mounting trolley mounted on the trolley working platform. The wheeltrack-type hydrauliclifting telescopic protective rack part comprises a wheeltrack-type hydraulic lifting telescopic protective rack, a protective rack lifting device and a protective rack lifting platform. The movable-type hydraulic work protective platform has the technical advantage that the safety degree of centralized operation is high.

[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 machinery and equipment have been adopted for tunnel construction, but the most dangerous excavation tunnel face excavation and support links are still inseparable from the construction workers. The progress of the tunnel face determines the progress of the entire tunnel, and Personal injury safety accidents in the tunnel are also near the tunnel face

How to ensure the personal safety of the personnel on the tunnel face and the construction progress of the tunnel face is the top priority. The traditional excavation bench at the tunnel face is mostly welded with I-beams, and there is no independent walking system. The main frame is heavy and needs to be towed by a loader, the speed is slow, the preparation time for each excavation and blasting is long, and it is easy to cause damage to the excavation bench, and it is inconvenient to maintain, the process connection time is long, and the original bench There is no protection for the upper part, and there is no protection for sudden rockfall, rockburst, and landslides, and the operators on the rack are prone to safety accidents

Especially in the construction of single-track tunnels, the working space in the tunnel is narrow, and the traditional working platform needs to occupy space, causing the safety step to exceed the control, which leads to uncontrollable safety risks in the entire tunnel construction
