Pier maintenance film covering device

Abstract

The invention relates to a pier maintenance film covering device. The film covering device effectively solves problems that a notch is prone to occurring in a traditional film covering mode, film covering is too thin, and severe weather cannot be effectively resisted, and the film covering device comprises two supports, the two supports are connected through a sliding rail, a sliding frame capable of moving along the sliding rail at a constant speed is installed on the sliding rail, a chain wheel and chain set is fixed to an upper end of the sliding frame, and a roller is fixed on the chain; the left side and the right side in the two supports are each detachably provided with a U-shaped frame, a reel is fixed to the outer side of the frame wall of the rear end of each U-shaped frame, a steel wire is wound and fixed to each reel, a frame wall of a front side of each U-shaped frame is of a telescopic pipe structure, and an end of each telescopic pipe is provided with a groove penetrating in the front-back direction; supporting rods are arranged on the outer side of the frame wall of the front side of each U-shaped frame at intervals, the supporting rods on the left U-shaped frame are fixedly connected with the U-shaped frames, the supporting rods on the right side can move front and back, and the right U-shaped frame is smaller than the left U-shaped frame.

Description

technical field [0001] The invention relates to the field of bridge pier maintenance equipment, in particular to a bridge pier maintenance coating device. Background technique [0002] The bridge piers need to be maintained during the construction process. During the maintenance, the bridge piers need to be covered with a film to prevent the water from evaporating too fast and causing cracks in the bridge piers. At this stage, for some high-height piers in the film covering process, generally by lifting equipment Hoist a roll of membrane to the upper end of the bridge pier and lower it slowly, and at the same time cooperate with the workers to drive the lifting rope of the lifting equipment at the lower or upper end of the bridge pier to make the whole roll of membrane rotate around the bridge pier, and finally realize that the membrane is wound on the bridge pier in a spiral manner. The bridge pier is directly wound by hand. At present, there is also an up and down moving d...

[0002] The bridge piers need to be maintained during the construction process. During the maintenance, the bridge piers need to be covered with a film to prevent the water from evaporating too fast and causing cracks in the bridge piers. At this stage, for some high-height piers in the film covering process, generally by lifting equipment Hoist a roll of membrane to the upper end of the bridge pier and lower it slowly, and at the same time cooperate with the workers to drive the lifting rope of the lifting equipment at the lower or upper end of the bridge pier to make the whole roll of membrane rotate around the bridge pier, and finally realize that the membrane is wound on the bridge pier in a spiral manner. The bridge pier is directly wound by hand. At present, there is also an up and down moving device fixed on the pier and equipped with circular motion to wrap the film on the pier. The above-mentioned film covering method has more or less the following problems : First, the entire roll of membrane cannot be effectively tensioned during the winding process on the pier, so that the spirally wound membrane is easy to loosen at the position where the membrane is pressed tightly. In the natural environment, especially in windy weather, it is very It is prone to gaps, and the water evaporates too fast at the gaps, resulting in a decrease in the quality of the pier. Second, during the coating process, only a single layer of film can be covered, which has poor resistance to outdoor environments and is prone to damage. Double or even multi-layer coatings cannot be effectively connected. fall off
