An upper swivel crane suitable for low headroom workshops

Abstract

The invention discloses an upper rotating crane suitable for a factory building with a low clearance height, which comprises a cart operating mechanism, a bridge frame, a lower trolley, an upper trolley, and electrical equipment. A cart operating mechanism is arranged at the end beam of the bridge frame; the bridge frame The lower trolley is set above the main girder; the electrical equipment is arranged on the bridge frame; the lower trolley adopts a concave structure in the middle; the upper trolley is set above the lower trolley; the upper surface of the main beam of the bridge frame is lower than the end girder of the upper surface. The invention adopts the concave structure of the lower trolley or the concave structure of the main beam, and reduces the effective height of the rotating part of the upper trolley by means of the central concave; the main beam of the bridge frame adopts a concave structure, which can reduce the height of the bridge frame. The adoption of the above structure reduces the overall height of the crane, so that the crane can be used in occasions where the headroom of the factory building is small. The invention has the advantages of compact structure, reliable operation and small height of the whole machine, and is suitable for workshops with low clearance height.

Description

technical field [0001] The invention belongs to the technical field of hoisting equipment, further belongs to the technical field of double-girder cranes, and specifically relates to an upper-slewing crane with compact structure, reliable operation, and suitable for workshops with low headroom. Background technique [0002] Cranes are lifting and transportation equipment that reduce heavy physical labor, improve work efficiency, and achieve safe production. In the material production and material circulation of various sectors of the national economy, cranes are widely used as key process equipment or important auxiliary machinery. There are many types of cranes, and the upper slewing crane (that is, the upper trolley can rotate the crane) is one of the most widely used lifting equipment used in the factory building. The upper slewing crane is mainly composed of five parts: the cart running mechanism, bridge frame, lower trolley, upper trolley and electrical equipment. The ...

AI Technical Summary

Problems solved by technology

The technological update of industrial production is very fast, and the original production process and process are often modified. According to the characteristics of the new production process and process, it is necessary to configure a rotating crane, but the headroom of the original factory building cannot be installed with a rotating crane. Renovate the factory building to increase the height of the factory building

This kind of plant renovation method requires a large investment and a long cycle, which affects the economic benefits of the enterprise.
