Hydraulic ship lift

Abstract

The invention discloses a hydraulic ship lift, which relates to a vertical ship lift. The ship lift in the prior art has complex structure, high failure rate and poor safety. The driving mechanism of the present invention is a hydraulic lifting manipulator evenly distributed on both sides of the ship lift box, which is connected with the handle of the ship lift box driven by a hydraulic cylinder. The hydraulic lifting manipulator is used to realize the self-lifting and self-locking of the hydraulic cylinder, and the reciprocating movement, just like the process of lifting heavy objects with human hands, realizes the lifting and landing of the ship lift. Through its reciprocating motion, a single short-stroke hydraulic cylinder can realize the hydraulic lifting function of large-distance operation; at the same time, it can be flexibly combined to realize the function of the ship lift to transport ships. The invention has the advantages of simple structure, low failure rate, safe and reliable equipment operation, strong flexibility, self-recovery function under partial failure, high operation efficiency, etc., and can be used for lifting ships at high dams.

Description

Technical field [0001] The invention relates to a vertical ship lift, especially a hydraulic ship lift. Background technique [0002] CN 1532345A discloses "a new kind of ship lift", which uses the brackets on both sides to form a circular ladder shape, so that the ship carrier or the ship container is arranged and combined step by step in a ladder cycle manner. This kind of ship lift exists The following problems: the system structure is complex, the organization is scattered, the failure rate is high, the safety is poor, and it is not easy to implement and maintain. This kind of ship lift requires the brackets on both sides to form a circular ladder shape, and its structure is complicated and difficult to manufacture; because it adopts a step-up work process in which the ship carrier or the ship carrier is arranged in a ladder cycle, it is inevitable to cause the ship carrier Or the ship carrier is constantly changing at the working stress point of the support, which is prone t...

Problems solved by technology

[0002] CN 1532345A discloses "A New Ship Lift", which utilizes the brackets on both sides to form a circular ladder, so that the ship carrier or the ship carrier box can be lifted step by step in a step-by-step cycle. This ship lift exists The following problems: complex system structure, scattered institutions, high failure rate, poor security, difficult to implement and maintain

This kind of ship lift requires the brackets on both sides to form a circular ladder shape, and its structure is complex and difficult to manufacture; because it adopts a step-up work process in which the ship carrier or the ship carrier is arranged in a stepwise cycle, it will inevitably cause the ship carrier Or the stress point of the ship-bearing box is constantly changing at the working point of the support, which is prone to eccentric loads, causing major failures, and the system has a relatively large risk; The connection process reduces the operating efficiency; the horizontal pin structure is adopted between the ship carrier or the ship carrier and the hydraulic cylinder, which is easily deformed by the gravity of the ship carrier or ship carrier, and it is difficult to operate for a long time. Once a failure occurs, usually It cannot be repaired; during operation, if one of the hydraulic cylinders in a group fails, it will cause the system to crash, and the safety is poor; there is no protection against fluctuations in the liquid surface and waterproof surface, and if the lifting speed is too high, the system will be unstable, and the safety is poor
