Dynamic balance ship compartment gravity ship lifting system

Abstract

The invention belongs to the technical field of water conservancy and hydropower engineering. According to the specific technical scheme, a dynamic balance ship compartment gravity ship lifting systemcomprises a ship chamber and concrete walls which are arranged in parallel and oppositely, a power balance mechanism is fixed at the top of the concrete wall body; under the traction of the dynamic balance mechanisms on the concrete wall bodies on the two sides, the ship chamber is in a gravity and traction balance state, beam prestress is preset in a top beam of the concrete wall, the action direction of the cross beam prestress is opposite to the gravity direction of the ship chamber, the prestress of the beam is the same as the gravity of the ship chamber, the beam prestress is counteracted with the ship chamber gravity, the outer side of the ship chamber and the concrete wall body on the same side are driven by a linear power device. According to the ship lift, the self weight is balanced through the power balance mechanism, the balance weight is reduced, the requirement for the construction strength of concrete walls on the two sides of the ship chamber is lowered, and safe operation of the ship lift is guaranteed through a dual-drive system.

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 system for dynamically balancing the gravity of a ship compartment. 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 main types of domestic vertical ship lift projects that have been built or are under construction 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 a part of the balanced cabin The launching type and the fully balanced hydraulic drive type are currently limited to ship lifts with small ship-passing scale ...

AI Technical Summary

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
