Wind power hoisting tower crane convenient to transfer

Abstract

The invention discloses a wind power hoisting tower crane convenient to transfer, and belongs to the technical field of hoisting machines. The tower crane comprises truss-type underframes, a self-rising jacking system, a bearing, a crane platform, a folded type gin pole, a boom, a rigid derricking stay cable system and tower crane accessories, wherein the truss-type underframes, the self-rising jacking system, the bearing and the crane platform are connected head to tail in sequence from top to bottom; the folded type gin pole is seated at the middle rear part of the crane platform; the boom is hinged with the front upper portion of the crane platform in an overhung manner and shares the same vertical plane with the folded type gin pole; and the rigid derricking stay cable system is arranged right above the boom and the two ends of the rigid derricking stay cable system are correspondingly connected with the head part of the boom and the folded type gin pole. According to the wind power hoisting tower crane convenient to transfer, by employing functional modular design and manufacturing, the structure of the tower crane is greatly optimized; and the tower crane has the advantages of having high lifting height, being convenient to transfer, convenient to remove and splice, convenient to transport, optimized in structure, reasonably stressed, reliable in quality, stable in performance, convenient to maintain, light in dead weight, economic and practical and having low demands on the bearing capacity of a foundation.

Description

technical field [0001] The invention belongs to the technical field of hoisting machinery, and more particularly relates to a tower crane for wind power hoisting which is convenient for transfer. Background technique [0002] Tower cranes can quickly achieve self-lifting by superimposing the height of the standard sections of the tower body. They have the advantages of small lifting height restrictions and large lifting ranges. They are widely used in construction fields with high lifting heights and frequent hoisting. However, tower cranes often complete all hoisting operations at the same fixed position. Therefore, traditional tower cranes generally use multi-layer and multi-channel attachment structures, and most of them need to prefabricate the foundation in advance, and the tower crane is installed on the fixed foundation. That is to say, traditional tower cranes cannot achieve rapid transition: before the tower crane is transported, most parts need to be completely dis...

AI Technical Summary

Problems solved by technology

However, the lifting height of mobile cranes represented by truck cranes and crawler cranes is often limited, which cannot meet the current height development needs of wind turbines. At present, the height of wind turbines has reached 150m or even more than 160m. Tower cranes are required
