Rapid film covering device for bridge pier

Abstract

The invention relates to a rapid film covering device for a bridge pier. The device effectively solves the problems that a traditional covering film is prone to generating notches, and the covering film is too thin and cannot effectively resist severe weather. According to the technical scheme, the film covering device comprises a base, the left side and the right side of the base are each provided with a chain wheel, the two chain wheels are connected through a chain, a roller arranged on the rear side of the chain is fixed to the chain, and a maintenance film roll is arranged on the roller in a sleeving mode. Two first reels which are symmetrically arranged left and right are arranged on the front side of the chain, two horizontal U-shaped frames with opposite openings are arranged on the rear sides of the first reels and the chain, the U-shaped frame on the left side is larger than the U-shaped frame on the right side, a second reel driven by a second stepping motor is rotationally installed on the frame wall of the rear side of each U-shaped frame, and a steel wire is wound on each second reel. The frame wall of the front side of each U-shaped frame is telescopic, the free ends of the steel wires on the second reels wind around the ends of the frame walls of the rear sides of the U-shaped frames, penetrate through the inner sides of the chains and then are wound on the corresponding first reels on the front sides, and the two steel wires are in a parallel state.

Description

Technical field [0001] The present invention relates to the field of conservation pier device, in particular a bridge pier fast coating apparatus. Background technique [0002] In the construction of pier construction process requires maintenance, it is necessary to prevent the film on the piers excessive evaporation during curing and cause cracks generated piers, during some stage of the coating film higher height for piers, usually by lifting equipment the roll of film is lifted into the upper end of the pier and slowly lowered simultaneously with the lifting sling device driving workers in lower or upper end of the pier so that the entire film roll is rotated around the pier, and ultimately the film is wound in a spiral manner on the pier, for some low altitudes pier directly wound artificial way, at this stage there are fixed on a vertically mobile devices pier and with a circular motion in order to achieve the film is wound on the pier, the following problem more or less of ...

AI Technical Summary

Problems solved by technology

[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
