Circular track crane and assembling method and disassembling method of circular track crane

Abstract

The invention discloses a circular track crane and an assembling method and a disassembling method of the circular track crane, relates to the field of engineering machinery, and aims to reduce the assembling and disassembling difficulty and cost of the circular track crane. The circular track crane comprises a platform, a cargo boom frame, a mast system and a supporting frame system. The platform is configured to provide supporting; the cargo boom frame is mounted on the platform; the mast system is mounted on the platform; the mast system is constructed to realize boom rising, working and boom falling of the cargo boom frame; the supporting frame system is mounted on the platform; and the supporting frame system is configured to achieve boom raising and boom falling of the mast system. According to the technical scheme, the use of auxiliary cranes is reduced, and the specifications of the auxiliary cranes are reduced; and due to the fact that the number of the auxiliary cranes is small, the occupied space is small, the assembling space is effectively reduced, the specifications of the auxiliary cranes are reduced, and the equipment operation economical efficiency is practically improved.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a ring-rail crane, a method for assembling the ring-rail crane, and a method for disassembling the ring-rail crane. Background technique [0002] With the continuous optimization and upgrading of engineering application fields, from the perspective of construction, hoisting operations are becoming more and more efficient and safe. The modular prefabrication of large-scale component ground in advance and the integrated hoisting of petrochemical tanks have increasingly become the development trend of various industries. The ever-emerging hoisting construction of ultra-large and ultra-heavy devices puts forward greater and more requirements for the capacity of hoisting machinery, and ring rail cranes have emerged as the times require. From a technical point of view, hoisting machinery is getting larger and larger, which will inevitably put forward higher requirements for the ass...

AI Technical Summary

Problems solved by technology

[0005] The inventors have found that at least the following problems exist in the prior art: the hoisting capacity of the ring rail crane is huge, and the size of its mast system is also very large. During the assembly and disassembly process of the ring rail crane, it is necessary to use multiple auxiliary large cranes to lift mast up

On the one hand, this increases the difficulty of installation and disassembly of the ring rail crane; on the other hand, it greatly increases the cost of assembly and disassembly of the ring rail crane and the floor area.
