Description
Technical field
The present invention relates to a kind of ship lift, especially relate to a kind of partial equilibrium hydraulic hoisting ship elevator, it belongs to water
Diuretic electrical engineering navigation structure field.
Background technology
Ship lift is a kind of common auxiliary building engineering of urban water system insertion, is using machinery or hydraulic means lifting
Ship is to overcome the navigation structure of the urban water system height of water.
The ship lift studied and build up both at home and abroad at present, by lifting device classification, can be divided into steel wire rope winding type, gear
The several types such as tooth bar climbing type, float-type and hydraulic floating type torque balanced ship-lifting mechanism.Domestic built ship lift
Most of steel wire rope winding type ship lift, mostly large scale ship, it is mainly used in solving high dam shipping navigation problem, to take
Comfortableness is less demanding, and most needs build main equipment room at the top of ship railway carriage or compartment room or the underground space, arrange lifting means or join
Weight, overall structure is more complicated.
With the development of urban water system connection project and the construction of middle-size and small-size key water control project, especially some tourism type cities
Rise, progressively built the ship lift of a collection of middle-size and small-size Tourism Nature, and for visitor's navigation, what ship lift was taken is comfortable
Property, safety have higher requirement.
Publication date is on 03 11st, 2015, in the Chinese patent of Publication No. 204199266U, discloses a kind of title
