Linear motor hydraulic ship lift

Abstract

The invention belongs to the technical field of water conservancy and hydropower engineering, and particularly relates to a linear motor driven hydraulic transmission ship lift capable of balancing dead weight. According to the specific technical scheme, the linear motor hydraulic ship lift comprises a ship chamber and concrete walls which are arranged in parallel and oppositely. A plurality of groups of constant-torque hydraulic transmission mechanisms are arranged at the top of the concrete wall body, a drum in the hydraulic transmission mechanism is connected with the ship chamber through asteel wire rope, and gravity information of the ship compartment is dynamically measured through the electronic scale sensors on the two sides of the ship compartment. The hydraulic motor drives thewinding drum to rotate to dynamically balance the gravity of the ship chamber; the stress balance of the ship chamber is realized; the linear motors on the two sides of the ship chamber drive the shipchamber to do reciprocating linear motion along the guide rails. Stable movement of the ship chamber in the guide rail is achieved through double fault tolerance of the hydraulic transmission mechanism and the linear motor, the requirement for the construction strength of a concrete wall of the whole ship lift is low, the ship lift can meet the ship lifting requirement for large tonnage and largelifting height, the overall construction cost is low, and practicability is higher.

Description

Technical field [0001] The invention belongs to the technical field of water conservancy and hydropower engineering, and specifically relates to a ship lift with a linear motor driven hydraulic transmission to balance its own weight. Background technique [0002] With the improvement of shipping conditions brought about by the development of river hydropower resources, high dam navigation technology puts forward new requirements. Compared with ship locks, vertical ship lifts have advantages and potential in navigating high dams. [0003] At present, the main types of vertical shiplift projects that have been built or are under construction in China are wire rope hoisting fully balanced type, gear climbing fully balanced type, and fully balanced hydraulic drive type; among them, the wire rope hoisting part of the balanced cabin The launching type and the fully-balanced hydraulic drive type are currently limited to ship lifts with small ship size and lifting height. At present, the...

Problems solved by technology

Due to the many turns of the wire rope on the drum, the length of the drum is very large, which makes it difficult to realize the axial arrangement of the main hoist, so it is necessary to increase the diameter of the drum and reduce the number of working turns of the drum The length of the drum is controlled, and the result is to increase the size of the mechanical transmission of the winch; even so, it still cannot satisfy the arrangement of the main hoist adapted to the length of the ship box
