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 ...

Embodiment Construction

[0040] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 Shown, the structural composition of the present invention has upper support 1 and lower support 2, and lower support 2 is main support frame, and upper support 1 and lower support 2 are respectively provided with upper wedge-shaped anchor 11 and lower wedge-shaped anchor 21, last wedge-shaped anchor 11 and The lower wedge anchors 21 are self-locking downward wedge anchors; the upper wedge anchor 11 and the lower wedge anchor 21 are respectively connected to the upper anchor cylinder 12 and the lower anchor cylinder 22, that is, the upper anchor cylinder 12 and the lower anchor cylinder 22 can be controlled by telescopic The upper wedge-shaped anchor 11 and the lower wedge-shaped anchor 21 make it in a working state or a relaxed state. The upper bracket 1 is connected to the main cylinder 3. The main cylinder 3 can control the rise or fall of the upper bracket 1 through telescopic control, t...
