Problems solved by technology
[0004] The technical problem to be solved by the present invention is to provide an intelligent tunnel second-lined surface spray maintenance trolley in view of the deficiencies in the above-mentioned prior art, which has a simple structure and a reasonable design. When the phenomenon of deviation from the center of the tunnel, the steering mechanism can adjust the deflection direction of the wheel box, so that the center of the trolley and the center of the tunnel can be restored to the state of coincidence, ensuring the accurate walking track of the trolley, and realizing the steering mechanism of the wheel box, spraying The automatic control of the spraying mechanism and the water supply mechanism solves the problems of difficulty in getting spraying water and poor spraying effect at the same time

The invention discloses an intelligent tunnel two-lining spraying maintenance trolley, which comprises a load-bearing gantry, a traveling device arranged at the bottom end of the load-bearing gantry, an arch spray device arranged at the top of the load-bearing gantry, and a The control system controlled by the arch ring spray device; the walking device includes a walking beam, a walking wheel box, a walking wheel and a steering mechanism, and the arch ring spray device includes a spray mechanism arranged at the top of the load-bearing gantry and connected with the spray mechanism. The control system includes a steering mechanism control module for controlling the steering mechanism, an automatic spray control module for controlling the spray mechanism, and an automatic water supply control module for controlling the water supply mechanism. The invention can restore the state of the trolley center and the tunnel center to overlap, ensure the accurate walking track of the trolley, realize the automatic control of the steering wheel box steering mechanism, the spray mechanism and the water feeding mechanism, and solve the problem of on-site spraying and spraying. Difficulty in spraying water and poor spraying effect.
Description
technical field [0001] The invention belongs to the technical field of tunnel engineering, and in particular relates to an intelligent tunnel second lining surface spray maintenance trolley. Background technique [0002] In tunnel engineering, after the concrete on the second lining is demoulded, it should be kept warm and moisturized in time. If the maintenance is not timely, the water in the concrete will evaporate, forming a dehydration phenomenon, which will make the formed gel cement particles unable to fully hydrate and transform into stable crystals. The cement particles lack sufficient adhesion, and the concrete surface will appear. Flaky and powdery detachment phenomenon. At the same time, the premature evaporation of water will cause shrinkage and deformation of the concrete, and shrinkage cracks will appear, which will affect the durability and integrity of the concrete. "Construction Technical Regulations for Railway Concrete Engineering" Q / CR 9207-2017 stipula...
