Full-hydraulic-lifting type ship lifter

Abstract

The invention relates to a full-hydraulic-lifting type ship lifter. The full-hydraulic-lifting type ship lifter comprises a ship reception chamber, a horizontal gate, an anti-collision device, two tower columns, locking devices, jacking and guiding devices, main lift cylinders, chamber bottom support beams, locking seats and guide rails, wherein the chamber bottom support beams are mounted at the bottom of the ship reception chamber; one ends of the main lift cylinders are connected with the tower columns, and the other ends of the main lift cylinders are connected with the end parts of the chamber bottom support beams; the locking devices are mounted on two sides of the top of the ship reception chamber, and the locking seats are mounted on the tower columns; the jacking and guiding devices are mounted on two sides of the ship reception chamber, one ends of the jacking and guiding devices are connected to the ship reception chamber, the other ends of the jacking and guiding devices are connected to the guide rails, and the guide rails are mounted on the tower columns. According to the full-hydraulic-lifting type ship lifter, the ship reception chamber is supported by the chamber bottom support beams, so that the loading condition of the ship reception chamber is definite, the stress, rigidity and operation security of the structure are good; as multiple cylinders are synchronously driven, lifted and locked, the ship reception chamber smoothly works and is securely locked; the full-hydraulic-lifting type ship lifter is simple and reasonable in integral structure and low in investment cost.

Description

technical field [0001] The invention relates to a ship lift, in particular to a fully hydraulic lift type ship lift, which belongs to the field of water conservancy and hydropower engineering. Background technique [0002] Ship lift is a common auxiliary construction project of river barrage dams. It is a navigable structure that uses mechanical devices to lift ships to overcome the concentrated water level drop on the channel. Compared with the ship lock device with the same function, under the condition of basically the same investment scale, it shortens the time for ships to cross the dam, improves the navigation efficiency and saves water resources. [0003] At present, the ship lifts researched and built at home and abroad can be divided into dry transport and wet transport according to the ship transport mode; according to the ship transport trajectory, they can be divided into two types: vertical ship lift and inclined ship lift. Among them, the vertical wet transpor...

[0005] Chinese Patent No. 200710061663.4 discloses a patent titled "Hydraulic Ship Lift", which uses a hydraulic lift manipulator to cooperate with a bamboo-type propulsion column to make the lift box (that is, the ship box) rise and fall step by step , to achieve a single short-stroke hydraulic cylinder to complete large-distance lifting, the lifting method is similar to the rack and pinion climbing ship lift, but the lifting speed of this ship lift is slow, and it also needs to be equipped with counterweights, the structural design is not simple and reasonable, and the ride is not comfortable enough , does not well overcome the above-mentioned defects in the prior art

[0006] Chinese Patent No. 200810233544.7 discloses a patent titled "a hydraulic lifting type ship lift". The ship lift becomes a piston structure by adding a seal between the buoy and the vertical shaft. The piston structure matches the head difference between the upstream and downstream as The ship-carrying box provides power for lifting, but the ship lift still needs to build a shaft, the structure is complex, and the requirements for sealing are high, and the above-mentioned defects in the prior art have not been well overcome
