Description

Technical Field

[0001] The utility model relates to the technical field of tower cranes, in particular to a detachable sleeve frame structure. Background Art

[0002] The frame is mainly composed of a main chord, a crossbeam, and a web. It is a truss structure that bears the vertical force and bending moment when the upper part of the tower crane is raised or lowered. At present, the frame of the tower crane is in the form of a rectangular frame structure. The crossbeam and the web are directly welded to the main chord, thereby forming a surface with each other, and finally forming a square fixed frame. In the prior art, the frame is mainly formed by welding and splicing. The welding process is prone to cause deformation of the four sides, asymmetry, and difficulty in installation. In addition, the square frame is difficult to load during transportation, occupies a large space, and increases transportation costs. If the cross-section of the frame is too large, it will also lead to inability to be packed, which does not meet the export transportation requirements. Utility Model Content

DETAILED DESCRIPTION

[0017] In order to facilitate the understanding of the technical solution of the utility model, a detailed description is given below in conjunction with the accompanying drawings and specific embodiments.

[0018] Example 1

[0019] like Figure 1-6 As shown, the detachable casing structure is divided into four surfaces, a casing lifting surface, a casing introduction surface and two casing side surfaces;

[0020] like Figure 3 As shown, the jacket lifting surface includes two jacket lifting plates 1 and a jacket rear beam 2. The jacket rear beam 2 is installed at the bottom between the two jacket lifting plates 1 and connected with a hinged hole bolt 11 to achieve the corresponding detachable function;

[0021] like Figure 5 As shown, the jacket introduction surface includes two jacket single supports 4, a support rod 9 and a jacket front guard plate 10. The two jacket single supports 4 stand on both sides, and are connected in the middle by the support rod 9 and the jacket front guard plate 10, and are connected by hinged hole bolts 11 to achieve the corresponding detachable function;
