Foldable arch-frame type tunnel waterproof board installation vehicle

Abstract

The invention relates to a foldable arch-frame type tunnel waterproof board installation vehicle. The foldable arch-frame type tunnel waterproof board installation vehicle comprises a lower vehicle body, a supporting frame arranged on the lower vehicle body and stretching / folding the lower vehicle body, a display board arm frame, a display board compression device arranged on the display board armframe, a travelling rail capable of stretching / folding, a travelling trolley and a rotating arm frame; the display board arm frame and the display board compression device are stretched / folded with the travelling trolley, the rotating arm frame located on the supporting frame drives the display board arm frame and the display board compression device to move along the travelling rail through thetravelling trolley, and thus the installation of the tunnel waterproof board is achieved. According to the foldable arch-frame type tunnel waterproof board installation vehicle, the waterproof board can be automatically laid along a design section, the labor intensity of workers is lowered, the construction speed and the efficiency are high, the travelling rail, the supporting frame and the display board arm frame all can be folded, after being folded, the space occupied by the equipment can be greatly lowered, the whole equipment can be transported without disassembly and assembly, and be quickly unfolded after arriving at the construction site to conduct operation, and construction auxiliary time is greatly shortened.

Description

technical field [0001] The invention relates to the field of tunnel excavation, in particular to a foldable arch type tunnel waterproof board installation vehicle. Background technique [0002] After the initial support is completed in the tunnel construction, a layer of waterproof material needs to be laid before the construction of the secondary lining. The laying of waterproof material is an important part of tunnel construction. The quality and progress of waterproof material laying directly affect the quality of tunnel construction. The traditional construction method of waterproof material laying is manual laying. During manual laying, the waterproof material roll needs to be rotated to unfold the waterproof board, and the waterproof material roll needs to be moved at the same time. However, due to the heavy weight of the waterproof material roll, it is very awkward to operate and requires a lot of labor. The laying time is long, and the waterproof material is not well...

AI Technical Summary

Problems solved by technology

The tunnel automatic waterproof board trolley realizes the automatic release of the waterproof board through the cloth rolling device, and uses the rolling device to press the deployed waterproof cloth and the tunnel wall tightly to avoid wrinkles of the waterproof board, and the rolling device can walk along with it. The trolley moves along the trolley track and is suitable for the entire tunnel profile, but because the trolley travels in the form of a rack and pinion, the rack is installed on the upper surface of the rail head of the trolley track, and the tunnel sections are mostly connected by different curvatures. Smooth curve, the running track is also a smooth curve connected by different curvatures, so the rack needs to be processed into different curvatures and the entire section needs to be arranged. The rack requires high machining accuracy, difficult processing, long length, high production cost, and its volume It is a fixed size, cannot be folded, and is not easy to carry

Patents CN204267053U and CN107559025A respectively provide a waterproof board trolley that adopts hoisting structure and sprocket chain to make the trolley walk on the trolley track. Pulleys or sprockets are arranged in multiple places along the running track and the door frame. Many, the transmission setting and installation are complicated, the production cost is high, and the installation and maintenance are inconvenient
