Assembling method of circular track crane and circular track crane

Abstract

The invention relates to an assembling method of a circular track crane and the circular track crane. The assembling method of the circular track crane comprises the following steps that an arm frame and a mast are transversely placed on a base plate, the first end of the arm frame is hinged to the base plate, the second end of the arm frame is suspended, the first end of the mast is hinged to the base plate, and the second end of the mast is suspended; an auxiliary support is vertically arranged on the base plate, and the auxiliary support upwards supports a steel wire rope connected between the second end of the mast and the second end of the arm frame; the steel wire rope is shrunk, the second end of the mast is lifted under the tension action of the steel wire rope due to the fact that the weight of the arm frame is larger than that of the mast, when the second end of the mast is lifted to the first height, the steel wire rope is separated from the auxiliary support, and when the second end of the mast is lifted to the second height, hoisting of the mast is completed; and the second height is greater than the first height. A mast self-lifting mode is adopted, so that the use of a plurality of large auxiliary cranes is avoided, the disassembly and assembly cost is reduced, and the disassembly and assembly efficiency is improved.

Description

Technical field [0001] The present invention relates to the field of mechanical engineering, in particular, it relates to a method of assembling a cyclic ring and crane track rail cranes. Background technique [0002] With engineering applications constantly upgrading, from the construction level, lifting more and more prominent efficiency and security, a large component of the ground ahead of modular prefabricated, integrated petrochemical tank lifting more and more become a trend, the emerging super super-heavy lifting construction equipment, made larger and more demands on the capacity of lifting equipment; from a technical perspective, more and more large-scale lifting equipment, must put forward higher requirements for machine assembly and disassembly; from the operational level in terms of , lifting large-scale machinery will be assembled to bring the high cost of the problem, but the process of dismantling the ring rail crane auxiliary crane tonnage biggest need is lifting...

AI Technical Summary

Problems solved by technology

The use of multiple large auxiliary cranes will lead to high disassembly costs, and the use of auxiliary cranes will make disassembly and assembly efficiency extremely low

When an auxiliary crane is used to lift the mast and mast bracket, a sling is generally added to the head of the mast. The height of the center of the hook is usually tens of meters. After the mast is in place, it will be difficult to unhook the sling, and people often need to climb up to the head of the bracket to remove it. suspenders

And the auxiliary crane has a certain cable pull, and there is a certain risk in operation
