A bridge pier maintenance device

Abstract

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

Description

technical field [0001] The invention relates to the field of bridge construction, in particular to a bridge pier maintenance device. 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, the w...
