Abstract

The invention provides a concrete protective film laying device. The concrete protective film laying device comprises a laying trolley and a fixing pile, wherein the rear end of the laying trolley isrotatably provided with a rotary shaft for placing a film roll, and is further provided with a driving clamping discharging roller and a driven clamping discharging roller; the driving clamping discharging roller is connected to a servo motor; the servo motor is connected to a controller; and a plurality of photoelectric sensors for monitoring the rotation speed of a roller are further arranged ona rack. While the laying device is used, one end of a film is fixed through the fixing pile, the servo motor drives the driving clamping discharging roller and the driven clamping discharging rollerto outwards convey the film continuously; and moreover, the motion speed is further monitored through the photoelectric sensors, so that the film releasing speed is consistent with the motion speed ofthe laying trolley. Compared with the prior art, the concrete protective film laying device has the advantages of improving the laying efficiency, being not liable to have folds, and being high in 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...
