Abstract

The invention provides a concrete protective film laying device, which includes a laying trolley and a fixed pile. The rear end of the laying trolley is rotatably provided with a rotating shaft for placing a film roll, and is also provided with an active clamping discharge roller and a driven clamping discharge roller. , wherein the active clamping discharge roller is connected to the servo motor, and the servo motor is connected to the controller; the frame is also provided with a plurality of photoelectric sensors for monitoring the rotation speed of the drum. When the laying device of the present invention is used, the film One end of the film is fixed by a fixed pile, and the servo motor drives the active clamping feeding roller and the driven clamping feeding roller to continuously convey the film outward, and also monitors the speed of motion through a photoelectric sensor, so that the speed of film release is consistent with the movement of the laying trolley. The speed is consistent. Compared with the prior art, the present invention not only improves the laying efficiency, but also is less prone to wrinkles and has high laying quality.

Description

technical field [0001] The invention relates to the technical field of building construction equipment, in particular to a concrete protective film laying device. Background technique [0002] At present, concrete is widely used in the field of construction engineering. After the concrete is poured, if the climate is hot and the air is dry, if it is not cured in time, the moisture on the concrete surface will evaporate too quickly and dehydration will occur, so that the cement particles that have formed a gel cannot fully Hydration cannot be converted into stable crystals, and lacks sufficient cohesive force, which will cause plastic shrinkage of the concrete, cracks on the surface, and formation of flakes or powdery peeling, which will affect the strength of the concrete. In addition, during the curing period of concrete, if the internal moisture evaporates prematurely and excessively, it will not only affect the hydration degree of the cement, but also cause a large drying...
