Folding type cloth hanging trolley

Abstract

A folding type cloth hanging trolley comprises a chassis used for walking in a tunnel, a first rotating arm is hinged to the chassis, a second rotating arm is hinged to the first rotating arm, and a cloth hanging frame is connected to the second rotating arm. The first rotating arm and the second rotating arm are driven by the control system to rotate, so that the cloth hanging frame moves in the circumferential direction of the tunnel arch face. The cloth hanging frame is used for hanging cloth and comprises a reel used for installing a waterproof cloth roll, a pressing roller used for pressing the waterproof cloth on the inner wall of a tunnel, a gluer and a movable nail gun, and the nail gun is used for nailing the waterproof cloth on the inner wall of the tunnel. Compared with an existing cloth hanging trolley, the hanging length of the rotating arm of the cloth hanging trolley can be reduced in a multiplied mode, the passing ability is improved, and the transition difficulty of the cloth hanging trolley is greatly reduced; the cloth hanging device is suitable for cloth hanging operation of different tunnel arch faces, the universality is high, and the manufacturing cost of construction equipment is reduced; automatic cloth paving, nailing and gluing are achieved, the mechanical degree is high, the efficiency is high, and the labor cost is reduced.

Description

technical field [0001] The invention relates to the field of tunnel engineering equipment, in particular to a foldable hanging cloth trolley. Background technique [0002] When excavating the tunnel, in order to prevent the tunnel from leaking and prolong the service life of the tunnel, it is necessary to lay a waterproof cloth on the inner wall of the tunnel. When hanging the cloth, it is necessary to use a nail gun to nail the waterproof cloth to the inner wall of the tunnel, and glue the seams between the waterproof cloth. [0003] At present, construction personnel need to use hanging cloth trolleys to carry out hanging cloth operations. The patents whose application numbers are CN109356624A and CN110966024A disclose the structure of the existing hanging cloth trolley, and the existing hanging cloth trolley has the following problems: [0004] 1. The existing hanging cloth trolley has an arched portal frame that is similar to the tunnel arch surface. The arched portal ...

AI Technical Summary

Problems solved by technology

[0004] 1. The existing hanging cloth trolley has an arched portal frame that is similar to the tunnel arch surface. The arched portal frame is huge in size and the road passability is poor, which makes it difficult for the existing hanging cloth trolley to transfer;

[0005] 2. Since the tunnel arches that need to be constructed are not necessarily the same, the arched portal frame of the existing hanging cloth trolley cannot be applied to all tunnel arches, resulting in the poor versatility of the existing hanging cloth trolley, which improves the Manufacturing costs of construction equipment;

[0006] 3. Most of the existing hanging cloth operations are spread, nailed and glued manually. The degree of mechanization is low, not only the construction efficiency is low, but also the labor cost is increased.
