[0004] The current scaffolding has a simple structure and can only be used on flat ground. However, the ground of railway tunnels is often paved with many stones. The ground is uneven, so it is difficult to erect scaffolding and ensure the stability of the scaffolding; Inspection and maintenance, so it is necessary to frequently move the position of the scaffolding on the ground. At the same time, because the tunnel section is arc-shaped, workers often need to adjust the height of the scaffolding when maintaining the top of the tunnel. However, the current scaffolding is in terms of displacement and height adjustment. Complicated and often requires excessive worker time and effort

The invention relates to the technical field of railway scaffolding, and discloses a scaffolding for railway tunnel maintenance, which includes rail rollers, and the rail rollers are provided with slide rails, connecting rails, support legs, slideways, sliders, support plates, fixing seats, fixing Slot, fixed rod, bottom rod, extension rod, connecting groove one, embedded rod one, block, fixed cylinder, support block, platen, embedded rod three, stepping rod and connecting rod. The invention is easy to assemble, disassemble and transfer, and has good stability and safety for high-altitude operations, and is easy to adjust the horizontal position and vertical height during operation, and is suitable for tunnels of different widths, and its top matches the cross-sectional shape of the tunnel. The operation of a large area can be completed by setting up the device once, and compared with the prior art, the number of times of setting up the scaffold is reduced, and the working time and energy of the staff are saved.
Description
technical field [0001] The invention relates to the technical field of railway scaffolding, in particular to a scaffolding used for railway tunnel maintenance. Background technique [0002] In order to eliminate the diseases of railway tunnels and ensure the safety of trains, it is often necessary to maintain and repair the tunnels. Tunnel diseases mainly include insufficient boundaries, lining cracks, water leakage and pollution. [0003] Scaffolding is needed for the maintenance of railway tunnels. Scaffolding refers to various supports erected on the construction site for workers to operate and solve vertical and horizontal transportation. Mainly for the construction personnel to work up and down or the peripheral safety net enclosure and high-altitude installation components, etc., the scaffolding materials usually include: bamboo, wood, steel pipe or synthetic materials. [0004] The current scaffolding has a simple structure and can only be used on flat ground. Howev...
