A pier covering device

Abstract

The invention relates to a bridge pier film covering device, which effectively solves the problems of large investment in film covering operation equipment for high bridge piers, low efficiency, unsatisfactory effect, and high construction risk; the technical solution includes a climbing unit and a film covering unit, and film covering The unit includes a bearing plate that can rotate around the bridge pier. On the bearing plate, a water spray pipe, a rotating shaft, an air spray pipe and an arc-shaped groove are arranged. The arc-shaped groove is concentric with the second ring frame, and a A vertical shaft that can slide along an arc-shaped groove. The vertical shaft is fixedly connected with a roller parallel to it. The roller is equipped with a clamping unit that can clamp the film head. The roller and the vertical shaft can slide in the arc-shaped groove so that Pull out the film head; the present invention can realize the film coating work of the bridge pier without using lifting equipment and without the need for staff to climb to the top of the bridge pier, which greatly reduces the input and occupation of the lifting equipment or ladder for the pier coating, and Construction personnel do not need to climb high to work, which greatly reduces the construction risk.

Description

technical field [0001] The invention relates to the field of bridge construction, in particular to a film covering device for bridge piers. Background technique [0002] After the bridge pier is poured and the formwork is removed, the internal concrete will undergo hydration and exothermic reaction. In order to prevent the moisture in the pier body from evaporating too quickly and causing the concrete to form cracks, it is necessary to wrap a layer of plastic film on the outside of the pier; the winding film generally requires winding from top to bottom , that is, the lower layer is laminated to the upper layer, which can prevent the precipitated water from flowing out from the film gap; currently, when covering high bridge piers, a crane is required to lift the film roll through a rope, and a worker is transported by a crane or a ladder At the top of the pier, the worker fixes the film head on the pier, and then the crane gradually lowers the film roll, and at the same time...

AI Technical Summary

Problems solved by technology

[0003] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a bridge pier coating device, which effectively solves the problems of high equipment investment, low efficiency, unsatisfactory effect and high construction risk.
