Integral main beam structure for double main beam hoisting equipment

Abstract

The invention discloses an integral main beam structure for double main beam hoisting equipment. The integral main beam structure comprises a first main beam and a second main beam which are of the same structure, and the first main beam and the second main beam are arranged in parallel; hoisting trolley equipment is arranged between the first main beam and the second main beam, wherein the first main beam is a truss composed of an upper cover plate, a lower cover plate and trolley tracks; the upper cover plate is arranged on the upper plane of the truss, and the lower cover plate is arranged on the lower plane of the truss; the upper surface of the first main beam is provided with the upper cover plate, and the lower surface of the first main beam is provided with the lower cover plate; the trolley tracks are located on the upper surface of the upper cover plate; one side, deviating from the second main beam, of the first main beam is provided with a maintenance platform, and one side, deviating from the first main beam, of the second main beam is provided with a hoisting trolley power supply system. The inventory specifications of plates and sectional materials are reduced, and quick transport and assembly of combined double beams can be achieved.

Description

technical field [0001] The present invention relates to equipment among double main girders, in particular to an integrated main girder structure suitable for double main girder bridge type, gantry crane and other lifting equipment. Background technique [0002] At present, with the rapid development of the domestic economy, various industries such as iron and steel, thermal power, petrochemical, mining, and ports are also rapidly forming their own scales, and higher and higher requirements are placed on the safety, efficiency, and energy saving of engineering equipment. Cranes have the advantages of simple structure, large load capacity, and small footprint. They are important handling equipment for mechanization in production workshops, stockyards, and warehouses, reducing physical labor and improving labor productivity. Therefore, they are widely used in industry. Various cranes can be seen everywhere in electrical assembly lines, metallurgical industry, railway transport...

AI Technical Summary

Problems solved by technology

Multiple plates are required for matching drilling, the production is cumbersome, the production cycle is long, and there are only bolt connections, the assembly accuracy is low during on-site installation, which affects product quality, only multiple bolt connections are used, and on-site installation is inconvenient

The running track of the trolley needs to be welded on site, which affects the appearance quality of the lifting equipment
