Embodiment Construction

[0008] Below the present invention will be further described in conjunction with the embodiment in the accompanying drawing:

[0009] Such as figure 1 As shown, it includes a flange plate 1, a rib plate 2, and a cylinder body 3.

[0010] Correct the roundness of the cylinder body 3 and roll it into shape; the flange plate 1 is tailor-welded flat; the flange plate 1 is welded to the cylinder body 3, and finally welded with rib plate 2 for reinforcement. After forming, turn the two flange plates 1 plane to the specified flatness, drill bolt connection holes on the flange plate 1 surface, and fix them with bolts during assembly, which is convenient and reliable, and can be used on cranes to increase height (such as lifting height , platform height).

Abstract

The invention relates to a round connecting cylinder device of a crane, in particular to a member used for increasing the height (such as lifting height and platform height) of the crane, and belongs to the technical field of lifting appliances. The device comprises a cylinder body and is characterized in that: a flange plate is welded on the cylinder body and rib plates are welded on the cylinder body for reinforcement. The device has the advantages of simple, compact and reasonable structure and convenient manufacturing, can directly change the height of the cylinder body, namely can increase the height of the whole crane, brings great convenience to construction means and decreases the workload of design.

Description

technical field [0001] The invention relates to a circular socket device of a crane, in particular to a component used for increasing the height (such as lifting height and platform height) on the crane, and belongs to the technical field of hoisting machinery. Background technique [0002] At present, in view of the crane's operating purpose and the different requirements of the user's crane lifting height, the same model often needs to be redesigned and calculated. It brings a lot of resistance to the extension and standardized management of the same type of cranes. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages, so as to provide a circular joint device that can directly change the height of the cylinder, that is, increase the overall height of the crane, greatly facilitate the construction means, and reduce the design workload. [0004] According to the technical solution provided by the present invention,...
