Problems solved by technology

The overflow loss generated by the closed brake under the compact structure is greater when the brake is released and works normally, which causes more obvious impact on system performance degradation and higher energy consumption
The pre-setting of the brake pressure cannot adapt to different working conditions and loads for high-efficiency and low-wear braking, and the life of the brake friction plate is short
The existing winch braking system cannot overcome the above shortcomings at the same time, and meets the requirements of marine winch braking system with small footprint, high safety, strong adaptability, low energy consumption and high reliability

Abstract

The invention discloses an ocean winch electro-hydraulic braking system based on a closed hydraulic brake and a control method. The brake system comprises an oil tank, a hydraulic pump, a three-phase asynchronous motor, a manual maintaining pump, a suck-back preventing valve, an emergency braking cartridge switching valve, the normally-closed floating type hydraulic brake, a coiling block brake disc, a coiling block rotation speed encoder, an energy accumulator, a flexible braking cartridge switch valve, a flexible braking pressure adjusting valve, a manual maintaining control valve, a safety valve and a PLC control device. The ocean winch electro-hydraulic braking system is simple in structure, small in occupied space, high in safety and adaptability, low in energy consumption and high in reliability, and efficient low-abrasion braking can be conducted on an ocean winch under different loads and work conditions.

Description

technical field [0001] The invention relates to a marine winch braking system, in particular to an marine winch electro-hydraulic braking system and a control method based on a closed hydraulic brake. Background technique [0002] Marine winches are mainly used in the retraction and release of deep-sea resource development equipment, ROV systems, and underwater towing systems. The closed brake normally uses the elastic recovery force of the spring or disc spring to brake the winch, which has high safety and is widely used in the field of marine winches. The control performance of the braking control system directly affects the braking energy consumption and the working life of the brake, which restricts the adaptability and safety of the marine winch. [0003] Patent 201510706460.0 discloses an electro-hydraulic proportional control system for mining hydraulic winches. Its braking system includes a brake pump station, a hydraulic control reversing valve, an electromagnetic ...
