Problems solved by technology

The number of single twisting circles should not exceed 5 circles. If it exceeds 5 circles, the force of twisting the wire rope is too strong, which will easily damage the wire rope (explode).
thus requiring a lot of labor and working hours

Embodiment 1

[0031] Embodiment 1: A crane luffing steel wire rope anti-twisting device, its structure is as follows figure 1 with figure 2 shown, including:

[0032] The connecting arm 1 is preferably a channel steel. The left side of the connecting arm 1 is fixedly connected with the upper end of the left steel pipe 2, and the lower end of the left steel pipe 2 is fixedly connected with the upper steel plate 3, and the upper steel plate 3 is detachably connected with the lower steel plate 5 by bolts 4. The right side of the connecting arm 1 is fixedly connected with the upper end of the right steel pipe 6, and the lower end of the right steel pipe 6 is fixedly connected with the upper steel plate 7, and the upper steel plate 7 is fixedly connected with the lower steel plate 9 by bolts 8.

[0033] refer to image 3 As shown, during installation, the upper steel plate 3 and the lower steel plate 5 are placed above and below the left pull plate 12 of the tower crane and fastened by bolts...

Embodiment 2

[0037] Embodiment 2: A kind of tower crane, this tower crane has tower body, left movable pulley group, left luffing steel wire rope group 11, middle steel wire rope group 10, right side movable pulley group and right luffing steel wire rope group 13,

[0038] Its left side moving pulley block has left side tie plate 12, and right side moving pulley block has right side tie plate 14. Wherein, the anti-kinking device shown in Embodiment 1 is installed on the tower crane. The state after the installation is complete, such as image 3 shown.

Abstract

The invention relates to a crane amplitude-variable wire rope anti-twisting device and method and a crane and belongs to the related technical field of engineering machinery. The device comprises a connecting arm. The two ends of the connecting arm are fixedly connected with two steel tubes correspondingly. The end, not connected with the connecting arm, of each steel tube is fixedly connected with an upper steel plate which is fixedly connected with a lower steel plate through fasteners. Through the design of a brand-new structure, the crane amplitude-variable wire rope anti-twisting device can be directly mounted on the tower crane to isolate an amplitude-variable wire rope in a usage state; and then the wire rope is prevented from twisting, and normal construction cannot be affected.

Description

technical field [0001] The invention relates to the related technical field of engineering machinery, in particular to a crane luffing steel wire rope anti-twisting device, method and crane. Background technique [0002] Today's large luffing jib tower cranes represent contemporary heavy-duty construction cranes with high lifting capacity, high lifting height and high lifting speed. The boom design of the large-scale boom tower crane adopts the "rod" structure, which has better stability than the "beam" structure of the flat-arm tower crane. The boom structure accounts for a smaller proportion of the whole machine structure, and the maximum lifting capacity is larger. [0003] The luffing mechanism of the boom tower crane is to meet the requirements of the working position of material loading and unloading, make full use of its own lifting capacity (the reduction of the amplitude can increase the lifting weight), realize the working mechanism of changing the amplitude, and u...
