Problems solved by technology

The hoist and the door body are connected by two suspenders. When the gate is lifted out of the door slot to the locked position, the structure of the two suspenders needs to be removed. Since the suspender structure is arranged within the scope of the door slot, it is at a high level during the dismantling process. In the air condition, affected by the structural design and installation characteristics of the suspender, the suspender faces three major difficulties during the disassembly process: difficulty in disassembly and assembly, difficulty in construction, and great safety risks

Abstract

The invention discloses a vertical ship lift large-scale working gate vertical hydraulic hoist boom efficient disassembly device and method, which includes a boom connecting shaft between the first section boom and the second section boom The disassembled lower platform between the connecting shafts between the booms, the upper platform for disassembling the connecting shafts between the booms is fixed on the top of the lower platform, and the upper platform for disassembling the connecting shafts between the booms is set There is a supporting shaft tooling, and the jacking shaft tooling is equipped with a jack for ejecting and dismounting the connecting shaft of the boom; it is used to disassemble the connecting rod connecting shaft between the second section of the boom and the working door The connecting door shaft disassembly platform, the connecting door shaft disassembling platform is matched with the jack and the jacking shaft tooling to realize the disassembly of the boom connecting door shaft. It can overcome various technical difficulties faced by the construction, and complete the efficient disassembly and assembly of the vertical ship lift large-scale work gate vertical hydraulic hoist boom with high quality and high efficiency.

Description

technical field [0001] The invention relates to a device and method for efficiently disassembling and assembling the boom of a vertical hydraulic hoist for a large working gate of a vertical ship lift, and is suitable for high-efficiency disassembly and assembly of the boom of a vertical hydraulic hoist for various types of vertical ship lifts. It provides a useful reference for the disassembly and assembly of various large multi-link and long-distance vertical hoist cylinder booms with similar structural characteristics in other engineering fields. Background technique [0002] The working gate of the lower sluice head of the Three Gorges ship lift is a sunken flat door, with an overall size of 28.84m×19.75m×4.72 m (width×height×thickness), and a weight of about 670t. It is operated under pressure by two 9000KN hydraulic hoists. The lifting head of the hoist cylinder and the lifting lug of the working gate are connected by two suspender rods, and the suspension rod, the lif...
