Description

Technical Field

[0001] The invention relates to the technical field of tower crane structures, in particular to a multi-purpose standard section of a tower crane. Background Art

[0002] The tower crane standard section is the main component of the tower crane and plays an important role in the composition of the tower crane. Multiple standard sections are stacked to form the tower crane body.

[0003] The standard sections of tower cranes are divided into integral standard sections and sheet-type standard sections according to whether they can be disassembled. The present application makes an improved design for the sheet-type standard sections. In engineering construction, standard sections of appropriate width are generally selected according to the weight of the hoisted objects and the hoisting height. However, in actual use, it is often necessary to temporarily hoist overloaded heavy objects. At this time, it is often necessary to temporarily adjust the goods and hoist larger standard sections, which undoubtedly delays the construction progress. For this purpose, the present application has specially designed a multi-purpose standard section structure. Summary of the invention

[0004] In order to make up for the above shortcomings, the present invention provides a multi-purpose standard section of a tower crane, which includes four main side prisms, two side plate frames are connected between adjacent main side prisms, and the two side plate frames are both horizontally or longitudinally assembled between two adjacent main side prisms.

[0005] Furthermore, the present application provides a multi-purpose standard section for a tower crane, wherein the side walls of the main side prisms are welded with two groups of side clamps along the busbar, the two groups of side clamps are arranged at 90° to each other, and the edges of the side plate frames are embedded in the side clamps and fixedly connected by bolts.

[0006] Furthermore, the present application provides a multi-purpose standard section of a tower crane, wherein oblique tie bars are connected between two transverse side plate frames.

[0007] The multi-purpose standard section of a tower crane provided by the present invention has the following beneficial effects compared with the prior art. On the one hand, when performing light or low-height lifting tasks, it is only necessary to install the two side plate frames between two adjacent main side prisms longitudinally. At this time, a tower body structure with a smaller width can be obtained, which is completely sufficient to meet light load and low-height lifting tasks; on the other hand, when heavy load or high lifting tasks are required, it is necessary to install the two side plate frames between two adjacent main side prisms horizontally. At this time, a tower body structure with a larger width can be obtained, which is more applicable. BRIEF DESCRIPTION OF THE DRAWINGS
