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

The invention belongs to the technical field of water conservancy and hydropower engineering, and particularly relates to a ship lift driven by a superconducting linear motor to balance self weight through electric transmission. According to the specific technical scheme, the superconducting linear motor electrical ship lift comprises a ship chamber and concrete walls which are arranged in parallel and oppositely. A plurality of groups of constant-torque electric transmission mechanisms are arranged at the top of the concrete wall body; a drum in the electric transmission mechanism is connected with the ship chamber through a steel wire rope; gravity information of the ship compartment is dynamically measured through the electronic scale sensors on the two sides of the ship compartment. The transmission motor drives the winding drum to rotate to dynamically balance the gravity of the ship compartment; the stress balance of the ship chamber is realized; the superconducting linear motorson the two sides of the ship chamber drive the ship chamber 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 electric transmission mechanism and the superconducting 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 large lifting 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 in particular relates to a ship lift driven by a superconducting linear motor and driven by an electric transmission to balance its own weight. Background technique [0002] With the improvement of navigation conditions brought about by the development of river hydropower resources, new requirements have been put forward for the navigation technology of high dams. Compared with ship locks, vertical ship lifts have advantages and potentials in navigating high dams. [0003] At present, the domestic vertical ship lift projects that have been built or are under construction mainly include wire rope hoisting full balance type, gear climbing full balance type, and full balance hydraulic drive type; among them, the wire rope hoist lifts part of the balanced cabin The launching type and the fully balanced hydraulic drive type are currently limited to ship lifts ...
