[0002] The design specifications of the hydraulic anchor winch require that when the operating handle of the anchor winch is in the position of the hydraulic anchor winch, the sliding amount of the hydraulic anchor winch cannot exceed 1m / min. At present, the hydraulic anchor winch generally does not have a Hydraulic brakes, so when the operating handle of the hydraulic anchor winch returns to the neutral position, the hydraulic components will leak, and the leakage will be different according to the quality of the selected hydraulic components, and also according to the design. The hydraulic system structure type is different, and its leakage will be different; most hydraulic anchor winches on the market currently have a certain slippage when the operating handle is in the middle position when the anchor winch is loaded, and some anchor winches The slippage is far greater than 1m / min
If the hydraulic anchor winch bears the self-weight of the anchor chain and anchor, the self-weight of the anchor chain and anchor will drive the hydraulic motor to rotate through the gearbox, and the speed will change from low to high. When the speed reaches a certain level, the hydraulic motor will run at high speed, resulting in The hydraulic motor is sucked and the hydraulic motor is damaged

Embodiment
[0019] A hydraulic anchor winch equipped with a hydraulic disc brake 1 device, the structure is as follows figure 1 As shown, it includes a hydraulic disc brake 1, a gear box 2 and a hydraulic motor 3 connected in sequence. The gear box 2 is provided with a gear shaft, and the hydraulic disk brake 1 is arranged on the gear shaft. The hydraulic anchor winch also includes an operating handle. The hydraulic disc brake 1 is provided with a spring assembly.
[0020] The hydraulic disc brake 1 is installed on the gear shaft of the first stage of the gearbox 2. When the hydraulic control handle is in the neutral position, the braking force of the hydraulic disc brake 1 overcomes the force on the gear shaft, so that the gear stops working and reaches the hydraulic anchor winch. Stop now, and the braking force of the hydraulic disk brake 1 is about 1.6 times of the rated load of the anchor winch. To meet the frictional hydraulic disc brake 1 slip protection gearbox 2 and other mecha...

Description
technical field [0001] The invention relates to a hydraulic anchor winch, in particular to a hydraulic disc brake of the hydraulic anchor winch. Background technique [0002] The design specifications of the hydraulic anchor winch require that when the operating handle of the anchor winch is in the position of the hydraulic anchor winch, the sliding amount of the hydraulic anchor winch cannot exceed 1m / min. At present, the hydraulic anchor winch generally does not have a Hydraulic brakes, so when the operating handle of the hydraulic anchor winch returns to the neutral position, the hydraulic components will leak, and the leakage will be different according to the quality of the selected hydraulic components, and also according to the design. The hydraulic system structure type is different, and its leakage will be different; most hydraulic anchor winches on the market currently have a certain slippage when the operating handle is in the middle position when the anchor winch...
