Dust-proof electric hoist for clean room

Abstract

The invention discloses a dust-proof electric hoist for a clean room, which comprises a steel structure main beam, an operating device connected with the steel structure main beam, a lifting device fixed on the steel structure main beam, and the lifting device. The hook device connected to the lifting device, and the electric control device used to control the work of the electric hoist and fixed on the main beam of the steel structure, is characterized in that the operating device, lifting device, hook device and electric control device Correspondingly arranged in four enclosed shells, and at the same time, a layer of inorganic anti-corrosion coating with anti-static powder embedded on the surface is provided on the outer surface of the steel structure main beam and the closed shell; the advantages of the present invention The advantages are that the structure is simple, the corrosion resistance is high, the dustproof level is high, and electrostatic adsorption can be effectively prevented.

Description

technical field [0001] The invention relates to an electric hoist, in particular to a dustproof electric hoist for a clean room. Background technique [0002] With the rapid development of industrialization and urbanization, the problems of ecological construction and environmental protection are becoming more and more serious, and with the increasing saturation of the national heavy industry, as well as the improvement of people's living standards and ideological meaning, people's living environment quality is also doubled. focus on. People's requirements for cranes are getting higher and higher in environments such as dust-free workshops, food, pharmaceutical production, precision manufacturing and assembly, and relevant requirements are put forward for lifting and logistics material handling equipment with indoor cleanliness and anti-static requirements— — Comply with the "Code for Clean Room Construction and Acceptance" 50591-2010 " and other relevant laws and reg...

AI Technical Summary

Problems solved by technology

[0003]With the development of electronics, aviation, precision machinery, pharmaceuticals, food and other industries and the continuous improvement of air cleanliness requirements, dust-free workshops have emerged as the times require, and General-purpose cranes cannot meet the requirements of the above-mentioned industries for air cleanliness, and at present, the equipment produced in the domestic lifting and material handling industry will produce solid particles and electrostatic adsorption of dust and hair to varying degrees during the use of conventional electric hoists. Can not meet the requirements of the relevant laws and regulations of the clean room; the specific disadvantages are as follows, the surface treatment of the main beam steel structure of the general electric hoist in the prior art adopts spray paint, the paint adhesion is poor, and the paint is easy to fall off during assembly and transportation, and the appearance It is difficult to achieve uniformity, and the surface often absorbs a large amount of dust due to the accumulation of static electricity; the open lubrication structure of the operating device of the general electric hoist can hardly prevent grease from entering the clean room environment, and it will also absorb dust to accelerate the wear of moving parts such as bearings. Wheels often rust due to the use of conventional materials over a long period of time; the reel in the hoisting device of a general electric hoist is usually equipped with a rope arrangement, and is made of common materials, which often pollute the clean room environment due to corrosion, and the cleanliness is up to It does not meet the requirements of the relevant standards of the clean room; the hook device of the general electric hoist adopts an open lubrication structure, is made of conventional materials, and the surface is painted and galvanized, and pollution sources are inevitable during use; the rope of the general electric hoist is lifted by a wire rope Heavy objects, dust and other pollutants will be generated during the friction between the wire rope and the pulley and reel; the electric control device shell of the general electric hoist is made of ordinary carbon steel, and the dustproof level is low
