Safety guaranteeing method and apparatus for vertical ship lift with counterweight

Abstract

The invention discloses a safety guaranteeing method and apparatus for a vertical ship lift with counterweight. According to the invention, the counterweight is divided into a part of gravity weight for balancing a ship chamber and a part of additional weight for balancing water in the ship chamber; the part of additional weight is divided into a part of torque weight and a part of safety weight, and the part of torque weight is connected with the ship chamber through steel wire ropes and a set of torque drums; the part of safety weight is connected with the ship chamber through steel wire ropes and a set of safety drums; the safety drums and the torque drums both are provided with brakes. The invention enables a safety problem under the conditions of severely decreasing water in the ship chamber of the ship lift and a severely damaged balancing system to be solved conveniently without increasing motor power of the ship lift. According to the invention, the advantages of low engineering cost, convenient operation control and high safety are obtained; the safety problem under the condition of complete loosing of water at any part of the ship chamber is solved, thereby greatly improving operation safety.

Description

technical field [0001] The invention relates to a safety guarantee method and device for a counterbalanced vertical ship lift, which belongs to the technical field of ships crossing dams. Background technique [0002] The counterweight vertical ship lift is a device commonly used for lifting ships when passing through embankments with water level differences. The current counterbalanced vertical ship lift includes a vertical lifting frame on which a set of fixed pulleys and a set of torque drums are installed; a steel wire rope is wound on the fixed pulley, one end of the steel rope is connected with the cabin, and the other end of the steel rope There is a gravity weight; the torque reel is also wound with a steel wire rope, and one end of the wire rope is also connected to the cabin, and the other end of the wire rope is tied with a torque weight; a group of torque reels are connected to the motor through a synchronous mechanism, and the motor is used for rotation. The mo...

Problems solved by technology

Therefore, in order to solve the safety problem in the "unbalanced" state, traditional ship lifts generally adopt methods such as setting safety lock devices along the way and strictly controlling the water level of the cabin to solve the safety problem when the cabin is seriously leaking, but these methods increase the operational control.
