Problems solved by technology

[0004] The embodiment of the present application provides a wall-attached device for a single-leg inclined steel tower crane and a single-leg inclined steel tower crane system to solve the problems caused by the small cross-section of the single-leg inclined steel tower and the excessively long length of the wall-attached pole in the related art. The triangular structure formed by the attached wall frame, the attached wall pole and the single-leg steel tower is not stable, and does not meet the problem of coating construction of the single-leg inclined steel tower with small cross-section

Abstract

The invention relates to a wall attaching device of a single-limb inclined steel tower crane and a single-limb inclined steel tower crane system, and relates to the technical field of bridge construction. The wall attaching device comprises a first wall attaching mechanism and a second wall attaching mechanism, and one end of the first wall attaching mechanism is used for being connected with the tower crane; the second wall attaching mechanism comprises a connecting rod arranged in the transverse bridge direction and two second wall attaching assemblies arranged on the two sides of the connecting rod correspondingly; the connecting rod is connected with the first wall attaching mechanism; a containing space used for containing the single-limb inclined steel tower is formed between the two second wall attaching assemblies, each second wall attaching assembly comprises a supporting rod and a first supporting leg which are arranged in the longitudinal bridge direction, and one end of each supporting rod is connected with the connecting rod; and one ends of the first supporting legs are vertically connected with the other ends of the supporting rods, and the other ends of the first supporting legs are used for being connected to the single-limb inclined steel tower. The single-limb inclined steel tower crane system comprises the tower crane, a single-limb inclined steel tower and the wall attaching device. The coating construction of the single-limb inclined steel tower with high height and small section is met, and the use of large hoisting equipment and overhead working trucks is reduced.

Description

technical field [0001] The present application relates to the technical field of bridge construction, in particular to a wall attachment device for a single-leg inclined steel tower crane and a single-leg inclined steel tower crane system. Background technique [0002] Due to its soft appearance, single-leg steel towers are widely used in the construction of cable-stayed bridges and suspension bridges. However, due to the small section and low rigidity of the single-leg inclined steel tower, it is difficult to install a tower crane. When painting the steel tower and constructing the auxiliary structures, large-scale hoisting equipment and aerial work vehicles are often used, resulting in high construction costs and high safety risks. [0003] In the related art, the wall-attaching device of the general tower crane connects the wall-attaching frame on the tower crane with the single-leg steel tower through three wall-attaching rods to form a stable triangular structure. Howe...
