Expressway tunnel waterproof board trolley walking device

Abstract

The invention discloses an expressway tunnel waterproof board trolley walking device. The expressway tunnel waterproof board trolley walking device comprises a trolley base and walking wheel bodies, wherein supporting seats are fixedly connected to the two opposite edges of the lower portion of the trolley base; the lower portions of the supporting seats are connected with walking wheel supports through bolts; and the walking wheel bodies are arranged on the walking wheel supports. According to the expressway tunnel waterproof board trolley walking device, the walking wheel bodies composed ofwalking sleeves and walking wheel base bodies are arranged, when the walking sleeves are abraded, the walking wheel bodies can be directly detached, the walking sleeves can be replaced, the whole walking wheel bodies do not need to be replaced, so that cost can be greatly saved; and the pretightening force of compression springs can be adjusted by rotating adjusting screw pieces, meanwhile, the floating gaps of the walking wheel bodies towards the two sides can be subjected to limiting adjustment, the walking wheel bodies can float at small intervals along wheel shafts in the walking process of the walking wheel bodies, and the problem that when the walking wheel bodies walk, derailing is caused due to the fact that the consistency of the intervals of walking rails is poor can be solved.

Description

technical field [0001] The invention belongs to the technical field of tunnel construction trolleys, and in particular relates to a traveling device for expressway tunnel waterproof board trolleys. Background technique [0002] During the construction of the tunnel, geotextiles and waterproof boards need to be laid successively on the tunnel section to form a water-proof and drainage-enclosed surface. At the same time, combined with comprehensive waterproof measures such as burying drainage pipes and installing construction joint waterstops, the effect of waterproofing the tunnel lining is achieved. The composite waterproof board has been widely used in current projects. In general, the waterproof board trolley can serve the laying of the waterproof board very well, and the walking device is an important part of the trolley. [0003] However, during the use of the existing waterproof board trolley traveling device, most of the traveling wheels are integrated. When the trave...

AI Technical Summary

Problems solved by technology

[0003] However, during the use of the existing waterproof board trolley traveling device, most of the traveling wheels are integrated. When the traveling wheel is damaged under pressure, the entire traveling wheel needs to be replaced, and the cost is high. At the same time, in the process of traveling the trolley Among them, the axial clearance of the walking wheels is small and cannot be adjusted, and the requirements for the consistency of the distance between the walking tracks are relatively high, and derailment occurs from time to time, which poses certain safety hazards
