Abstract

The invention provides a hydraulic synchronous lifting hoisting technology and hydraulic synchronous lifting hoisting equipment for ultra-large members. The hydraulic synchronous lifting hoisting technology is characterized in that: the members are hoisted at the lower end of a steel strand; the steel strand passes through two upper wedge-shaped anchors and lower wedge-shaped anchors which are automatically locked downwards and are controlled to release and clamp by an upper anchor oil cylinder and a lower anchor oil cylinder, and a main oil cylinder controls the lifting of the upper wedge-shaped anchors; the upper wedge-shaped anchors and the lower wedge-shaped anchors clamp or release the steel strand alternately, and the main oil cylinder lifts or lowers the upper wedge-shaped anchors, so that the members ascend or descend; and the members are hoisted to the specified position by circulating the ascending or descending step alternately or continuously. According to the hydraulic synchronous lifting hoisting technology, lifting weight, span and areas are not limited, and lifting height and lifting amplitude are not limited; the lifting process is safe, and the members can be locked at any positions reliably for a long time in the lifting process; the equipment is small in volume, light in weight, high in carrying capacity, high in automaticity, conveniently and flexibly operated, high in safety and reliability, wide in application range and high in generality.

Description

technical field [0001] The invention belongs to equipment assembly technology, in particular to a technology for assembling super-large components for cranes. Background technique [0002] The equipment for hoisting super-large components (such as gantry cranes over 1000t) includes: [0003] Use a crawler crane to lift. Crawler crane is the abbreviation of crawler crane. The disembarking site is a crawler walking mechanism, which walks on the crawler belt and lifts all parts of the crane through the lifting arm. The disadvantage of crawler crane hoisting is that it is troublesome to disassemble and assemble, and the boom cannot be stretched freely, which is too restrictive. [0004] Use a car crane to lift. The car crane is a combination of a car and a crane. It can work directly without assembly. There is a rotating drum under the inside of the boom, and a wire rope is wound on it. The wire rope passes through the pulley on the top of the next boom to move the previous ...
