Embodiment Construction
[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0018] see figure 1 , a winch hydraulic brake system with pressurization, including the total oil inlet P of the system, the total oil return port T, the safety valve assembly 1 and the brake assembly 2. A supercharger assembly 3 is arranged on the valve body of the safety valve assembly 1 , and the supercharger assembly 3 is integrated with the valve body of the safety valve assembly 2 . A one-way valve 4 is arranged between the safety valve assembly 1 and the supercharger assembly 3 . The total oil inlet P of the system is respectively connected with the control oil port X1 of the safety valve group 1, the oil inlet P1 of the supercharger 3, and the oil inlet P3 of the check valve 4; the total oil return port T of the system is respectively connected with the safety valve The oil return port T2 of valve group 1, the oil return por...

The invention discloses a winch hydraulic brake system with a boosting function. The winch hydraulic brake system comprises a safety valve assembly and a brake assembly. A valve body of the safety valve assembly is provided with a booster assembly. A one-way valve is disposed between the safety valve assembly and the booster assembly. A master oil inlet of the system is respectively communicated with a control oil port of the safety valve assembly, an oil inlet of the booster assembly and an oil inlet of the one-way valve. A master return oil port of the system is respectively communicated with a return oil port of the safety valve assembly, a return oil port of the brake assembly, and a return oil port of the booster assembly. An oil inlet of the safety valve assembly is respectively communicated with an oil inlet of the brake assembly, an oil outlet of the booster and a return oil port of the one-way valve. Pressure oil is guided from a master oil circuit, pressure of the oil is boosted by an added booster, the booster and the valve body of the safety valve assembly are integrated to one valve block, a pipeline is simplified greatly, fewer devices are used, space for the devices is reduced, operation and maintenance can be simpler, and manufacturing and operation cost of the whole system is reduced.
Description
technical field [0001] The invention relates to a hydraulic braking system, in particular to a winch hydraulic braking system with pressurization. Background technique [0002] The brake opening of the winch requires a certain pressure. When the winch is working with load, the working pressure is enough to open the brake, but when the winch is running without load, the working pressure is too low and often not enough to open the brake. [0003] For this problem, the traditional method is not to lead the pressure oil from the main oil circuit to control the brake, but to set up the brake control circuit to control the opening and closing of the brake. The pressure of the control circuit is designed to ensure that it can reach the opening pressure of the brake. For one thing, even if the winch works without load and the pressure of the main oil circuit is low, the normal opening of the brake will not be affected. However, because this method sets a control oil circuit indepen...
