Hoist for lifting and lowering materials for construction site construction

Abstract

The invention discloses a hoist for lifting materials for construction on a construction site, and relates to the technical field of hoists, in particular to a hoist for lifting materials for construction on a construction site. A gear plate is fixedly installed on the output shaft of the motor, a fixing block is arranged on the left side of the gear plate, a locking piece is hinged on the top of the fixing block, and a steel wire rope is fixedly connected to the right side of the locking piece. The bottom of the right end of the wire rope is fixedly connected with an electric telescopic rod. The hoist used for material lifting on construction sites, by setting a gear plate on the output shaft of the drive motor, when the hoist is not in use, the electric telescopic rod is used to pull down the locking piece, and then the wire rope pulls the locking piece to turn right. , so that the locking piece is stuck on the gear plate, preventing the drive motor from turning by mistake, avoiding the danger caused by the wrong start of the drive motor, and protecting the safety of personnel.

Description

technical field [0001] The invention relates to the technical field of hoisting machines, in particular to a hoisting machine for lifting materials used for construction on a construction site. Background technique [0002] Hoist, also known as winch, is a light and small lifting device that uses a reel to wind a wire rope or chain to lift or pull heavy objects. The hoist can lift heavy objects vertically, horizontally or obliquely. The hoist is divided into three types: manual hoist, electric hoist and hydraulic hoist. Mainly electric hoist. It can be used alone or as a component in machinery such as lifting, road building and mine hoisting. It is widely used because of its simple operation, large amount of rope winding and convenient displacement. It is mainly used for material lifting or flat dragging in construction, water conservancy projects, forestry, mines, docks, etc. [0003] In the process of rewinding the steel cables in the existing hoist, the steel cables w...

AI Technical Summary

Problems solved by technology

[0003] In the process of rewinding the steel cables in the existing hoist, the steel cables will be piled up and wound together, causing the steel cables to squeeze each other, which is likely to cause wire clamping and affect the release of the steel cables. At the same time, the existing The winding drum of the hoist is exposed to the outside, and accidents are prone to occur during the winding process of the steel cable. For this reason, we provide a hoist for lifting materials used in construction sites
