Ship lift intelligent control safety braking system and safety braking method thereof

Abstract

A ship lift intelligent control safety braking system comprises four safety braking subsystems, a transmission coordination control station and a transmission coordination control station network communication module. The four safety braking subsystems are arranged on four drive mechanisms of a ship lift drive system. Each safety braking subsystem comprises a safety brake, a work brake, a hydraulic control pump station, a motor rotation speed encoder for detecting the rotation speed of a drive motor, an in-situ electrical control unit for controlling the hydraulic control pump station and a hydraulic pump station pressure detecting device. By means of the system, the ship compartment braking deceleration, the braking distance and other indexes can meet the safety design requirement; and when the unbalance accident happens to a ship lift, emergency braking is conducted on the drive system, and a ship compartment safely and stably stops lifting running.

Description

technical field [0001] The invention relates to the field of water conservancy and hydropower engineering ship lifts, in particular to an intelligent control safety brake system suitable for the drive system of a counterweight vertical ship lift. Background technique [0002] At present, the most widely used vertical ship lifts for water conservancy projects are fully balanced wire rope hoisting vertical ship lifts, launching type wire rope hoisting vertical ship lifts and fully balanced rack and pinion climbing vertical ship lifts. The safety braking system is an important part of the safety guarantee system of the ship lift, an important part of the lifting drive equipment of the ship lift, and is crucial to ensure the safety of the ship lift. In the design of the safety braking system of the main hoist of the traditional ship lift, the braking force of the emergency braking is applied by the way of regulating the pressure of the working brake, and the electro-hydraulic pr...

Problems solved by technology

For power generation conditions, the braking force overcomes the external load to perform braking. In order to ensure the braking safety, the braking force is determined according to the maximum load. Due to the randomness of the load of the main hoist, when the actual load is small, a greater braking force will be generated. Shock; for electric working conditions, the applied braking force and the external load disc together produce a braking effect on the drive system, resulting in a braking acceleration several times that of the power generation working condition, and a greater impact on the drive system transmission mechanical equipment , resulting in equipment damage, or even a safety accident
