Method and structure convenient for maintenance of fixed winch

Abstract

The invention discloses a method and structure convenient for maintenance of a fixed winch. The method includes the steps that concrete bent is arranged above a gate in a dam, then a top platform is made on the concrete bent, a steel structure hoist chamber is arranged on the top platform, the fixed winch is arranged in the steel structure hoist chamber and fixed to the top platform, and a liftinghole is formed in the top platform in the steel structure hoist chamber; a bridge crane is arranged above the steel structure hoist chamber, the lifting range of the bridge crane covers all the ranges of the fixed winch and the lifting hole, and a lifting rope and a lifting hook of the bridge crane can be able to lift and lower parts of the fixed winch through the lifting hole; and a cover platecovers the lifting hole at usual times so that the fixed winch can be installed and maintained safely and conveniently. According to the method and structure convenient for maintenance of the fixed winch, the steel structure hoist chamber is arranged on the top platform of the concrete bent of the fixed winch, the weight is light, disassembly and installation are convenient, installation and maintenance are convenient, and safety for operators is ensured.

Description

technical field [0001] The invention relates to a method and a structure for convenient maintenance of a fixed winch, and belongs to the technical field of metal structures of water conservancy and hydropower projects. Background technique [0002] In hydropower and water conservancy projects, arc-shaped working gates are generally set in vent holes or bottom holes, but some projects also use flat working gates because of the difficulty in setting up and increasing investment. In order to prevent the accident from expanding when the plane working gate fails, a plane accident gate is generally provided in front of the plane working gate. Some projects also consider the need to repair the plane emergency gate slot, and set the plane maintenance gate in front of the plane accident gate. Generally, plane work gates, plane accident gates and plane maintenance gates are operated by fixed winches. The fixed hoist is installed on the bent frame. The hoist room above the existing b...
