Electric single-beam crane accurate in positioning

Abstract

The electric single-beam crane comprises a main beam, the main beam comprises a top plate, a middle plate and a bottom plate, the middle plate is fixedly installed at the bottom of the top plate, the bottom plate is fixedly installed at the bottom of the middle plate, and end beams are arranged on the left side and the right side of the main beam correspondingly; and a distance measuring sensor is fixedly mounted at the lower end of one side of one end beam. The crane is provided with a camera, a distance measuring sensor, a double-shaft motor, a gear, a tooth block and a first roller, so that when the crane is used, an object can be accurately hooked by the camera through a hook, the moving distance of an electric hoist can be accurately positioned through the distance measuring sensor, and the moving distance of the electric hoist can be adjusted more accurately through the tooth block and the gear; and meanwhile, a driving motor, a third rotating rod, a fourth rotating rod, a roller and a brush are further arranged, so that in the moving process of the first roller, the roller and the first roller can rotate together to clean dust on the bottom plate, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to an electric single-girder crane with accurate positioning. Background technique [0002] Electric single-girder cranes are widely used in workshops, warehouses, stockyards, etc. in machinery manufacturing workshops, metallurgical workshops, petroleum, petrochemical, ports, railways, civil aviation, power stations, papermaking, building materials, electronics and other industries. Low weight, light weight, small wheel pressure and other advantages. [0003] The electric single-girder crane includes a beam frame, a cart, a trolley electric hoist and a control mechanism. The beam frame is composed of end beams on both sides and the main beam connecting the end beams. The trolley runs on the main girder track, and thus lifts the workpiece at the corresponding position through the hook. [0004] The following problems exist when using traditional electric single-girder cranes: [00...

AI Technical Summary

Problems solved by technology

[0005] 1. After determining the position of the object to be picked up, the crane lowers the hook for hanging, but often the position of the object to be picked up at the bottom cannot be accurately referenced, resulting in inaccurate lowering of the hook;

[0006] 2. Due to the solid particles such as dust and sand falling on the main beam in the working environment such as the production plant, it hinders the rolling of the pulley, reduces the work efficiency, and reduces the service life of the roller
