Electric hoist bridge crane for clean room

Abstract

The invention discloses an electric hoist bridge crane used in a clean room, which comprises two steel structure main girders, two large vehicle end girders vertically connected with the two ends of the steel structure main girder, and The clean room electric hoist, electric control device and trolley power supply cable for the reciprocating movement of the trolley running track are characterized in that a towline is laid on one of the main beams of the steel structure, and the trolley power supply cable is placed inside the towline. At the same time, a layer of inorganic anti-corrosion coating with anti-static powder embedded on the surface is provided on the surface of the main beam of the steel structure, the end beam of the cart, the electric hoist in the clean room, and the electrical control device; , can effectively reduce the wear and tear of the power supply cable of the trolley, and at the same time have a high dustproof level and can effectively prevent electrostatic adsorption, effectively making up for the lack of electric hoist bridge cranes for domestic clean rooms, getting rid of foreign technical constraints, and meeting market demand at the same time.

Description

technical field [0001] The invention relates to a crane, in particular to an electric hoist bridge crane used in a clean room. Background technique [0002] With the development of society and the improvement of people's requirements for quality of life, the production environment and technical quality of products are particularly important. In fields with high cleanliness requirements, such as biotechnology, medical equipment, pharmaceutical production, and food production, even stricter requirements are put forward for the production environment. In these fields, cranes are often required for the lifting, installation and maintenance of production equipment However, ordinary cranes tend to generate dust during operation, absorb dust and cannot meet the requirements of the cleanliness level. With the development of biotechnology, medical equipment, pharmaceutical production, food production and other industries and the continuous improvement of air cleanliness requirements...

AI Technical Summary

Problems solved by technology

In areas with high cleanliness requirements, such as biotechnology, medical equipment, pharmaceutical production, and food production, even stricter requirements are placed on the production environment. In these areas, cranes are often required for the lifting, installation, and maintenance of production equipment. However, ordinary cranes tend to generate dust during operation, absorb dust and cannot meet the requirements of cleanliness level

With the development of biotechnology, medical equipment, pharmaceutical production, food production 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 air cleanliness requirements of the above industries , and the equipment produced by the domestic lifting and material handling industry at present, because conventional cranes will produce solid particles and electrostatic adsorption of dust and hair to varying degrees during use, cannot meet the requirements of relevant laws and regulations for clean rooms

[0003] The specific shortcomings of the general crane in the prior art are as follows, (1) the steel structure main girder, cart end beam, clean room electric hoist and electrical control device of the general crane The surface treatment is sprayed paint, but due to the poor adhesion of the paint, the paint is easy to fall off during assembly and transportation, and the appearance is difficult to achieve uniformity, and the surface often absorbs a large amount of dust due to the accumulation of static electricity; Installing the power supply cable of the trolley not only has potential safety hazards, is easy to wear, and is very easy to absorb dust
