Problems solved by technology

When the winch realizes anchoring and positioning, it will continuously release the cable with the anchor at the end to enter the sea. In the process of releasing the cable, the winch may release the cable too fast due to the excessive weight of the released cable. When the brake is used to brake the winch, the friction between the winch and the brake is too large, resulting in structural damage to the winch

Embodiment Construction

[0019] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0020] In order to facilitate the understanding of the present invention, the working scene of the winch control system in the present invention can be further described here. The winch in the present invention at least includes a support, a reel rotatably arranged on the support, a driving structure for driving the reel to rotate and a brake for braking the reel. During the working process of the winch, the driving structure drives the reel to rotate, and then the cables and other wires can be wound on the reel, or the original cables and other wires on the reel can be released. And when the reel needs to stop urgently or avoid the reel rotation, the control brake brakes the reel, hereinafter referred to as the brake brakes or release...

Abstract

The invention discloses a winch control system, and belongs to the field of hydraulic control. When a winch is required to release a cable, a two-position two-way reversing valve and a two-position two-way electromagnetic ball valve are electrified, and hydraulic oil in a fuel tank is extracted by a hydraulic pump and transported to the two-position two-way electromagnetic ball valve; and the hydraulic oil enters a proportional pressure reducing valve from a PA oil passage of the two-position two-way electromagnetic ball valve and enters a rodless cavity of a brake oil cylinder through a TA oil passage of the two-position two-way reversing valve, so that a brake is enabled to release the winch. In the process, the oil pressure of the hydraulic oil entering the brake oil cylinder can be controlled by the proportional pressure reducing valve, so that the brake is controlled to completely release the winch or partially loosen the winch, the winch is enabled to still be subjected to a certain amount of braking force of the brake while releasing the cable so as to maintain the speed of the winch releasing the cable to be relatively reasonable, and the situation that the winch is damagedduring braking due to excessive friction between the winch and the brake caused by too fast release of the winch is avoided.

Description

technical field [0001] The invention relates to the field of hydraulic control, in particular to a winch control system. Background technique [0002] The winch can locate and support the platform where the winch is located through actions such as cable anchoring. When the winch realizes anchoring and positioning, it will continuously release the cable with the anchor at the end to enter the sea. In the process of releasing the cable, the winch may release the cable too fast due to the excessive weight of the released cable. When the brake is used to brake the winch, the friction between the winch and the brake is too large, resulting in structural damage to the winch. Contents of the invention [0003] An embodiment of the present invention provides a winch control system, which can reduce the possibility of damage to the winch. Described technical scheme is as follows: [0004] An embodiment of the present invention provides a winch control system. The winch control s...
