Full flat type balance vertical ship lift adaptive to ship reception chamber outlet-inlet water

Abstract

The invention relates to a full flat type balance vertical ship lift adaptive to ship reception chamber outlet-inlet water. The invention aims to provide the full flat type balance vertical ship lift adaptive to the ship reception chamber outlet-inlet water, and the vertical ship lift has the advantages of convenience in operating control, higher security and better economy. The technical scheme of the invention is as follows: the vertical ship lift comprises pulley blocks arranged on two side dam bodies of a lifting well, a group of main hoisting drums and a group of controllable balancing weight winding drums and a ship reception chamber which can move up and down along the lifting well; the vertical ship lift is characterized in that the main hoisting drums are wound with a plurality of steel wire ropes, one end of each steel wire rope is connected with a moment weight, and the other end of each steel wire rope is connected with a hanging beam; the controllable balancing weight winding drums are wound with a plurality of steel wire ropes, one end of each steel wire rope is connected with a controllable balancing weight, and the other end of each steel wire rope is connected with a hanging beam; and the lower end of each hanging beam is fixed on the ship reception chamber through a group of lifting hydraulic cylinders, and a locking device is arranged between the ship reception chamber and the hanging beam. The full flat type balance vertical ship lift provided by the invention is suitable for establishing navigation structures on navigable rivers the water level amplitude of which is outsize.

Description

technical field [0001] The invention relates to a ship lift, in particular to a fully flat and vertical ship lift suitable for entering and exiting water from a ship-holding compartment. It is suitable for navigable facilities to overcome high water level drop, especially for navigable structures built on navigable rivers with large water level fluctuations. Background technique [0002] At home and abroad, there have been many successful examples of using the vertical ship lift scheme as a navigation facility project to overcome the high water level drop. Since the 1990s in my country, the vertical ship lift scheme has been successfully implemented in the navigation structures of a number of hydropower projects. The advanced engineering construction practice has effectively solved the technical problems of high dam navigation. The vertical ship lifts that have been built in China all adopt the wire rope hoisting scheme. The main types are fully balanced vertical ship lifts ...

Problems solved by technology

[0004] Taking the Yantan vertical ship lift as an example, the water entry and exit process downstream of the ship-holding box is completed by the winch-type main hoist at low speed. The weightlessness of the water-entry part of the ship-bearing box structure, but the lifting distance during the unbalanced process is less than 4% of the full lift, and the main hoisting system is to drive the ship-bearing box into and out of the water and needs to be configured according to the maximum unbalanced load. times the driving power and transmission system, not only technically unreasonable, but also poor in economy
