Problems solved by technology

[0003] In order to solve the problem of low construction quality due to high labor intensity in laying waterproof boards, the present invention provides a tunnel waterproof board laying equipment
During the tunnel laying operation, put the waterproof board roll on the rotating shaft, and then start the motor. At this time, the motor drives the chain to rotate, thereby driving the transmission gear and the plank car to make an arc-shaped movement along the guide pipe. During the movement, through the lifting cylinder Control the waterproof board to be close to the tunnel section, so as to realize the laying of the waterproof board quickly and efficiently, and overcome the problem of low construction quality caused by the high labor intensity in the laying of the existing waterproof board

Abstract

The invention particularly relates to a device for paving tunnel waterproof boards, which solves the problem of low construction quality caused by large labor intensity in pavement of waterproof boards. The device comprises a gantry steel frame which is externally connected with support bars, wherein a reinforced rod is fixed between two support bars, guide tubes are arranged above two support bars, and a ribbed rod is fixed between two guide tubes, a chain box is respectively fixed on each of the ribbed rod and the reinforced rod, a motor is arranged below the support bars, chains are externally connected between the two chain boxes and the motor, and an output shaft of the motor is provided with a power gear, a paving cart is arranged on the guide tubes and consists of a chassis, a drive gear is arranged on the lower part of the chassis, the other end of a lift hydraulic cylinder is provided with a support base, and a rotation shaft is penetrated through the support base. The device provided by the invention greatly lightens the labor intensity, guarantees construction quality and efficiency, has low requirements on construction environments, and has the advantages of simple structure, convenience for making and low cost.

Description

technical field [0001] The invention relates to tunnel laying equipment, in particular to a tunnel waterproof board laying equipment. Background technique [0002] In order to avoid water leakage, the tunnel must be laid with waterproof materials. The waterproof board is the main component of the waterproof material. Therefore, the laying quality of the waterproof board is directly related to whether the tunnel leaks. The commonly used waterproof board laying platform now only provides a platform for the construction workers to stand on. Because the waterproof board is relatively heavy, the labor intensity of the workers during the construction process is too high, and they are often operated in violation of regulations, which cannot guarantee the construction quality, resulting in water leakage in the tunnel. occur. Contents of the invention [0003] In order to solve the problem of low construction quality due to high labor intensity in laying waterproof boards, the pre...
