Embodiment Construction

[0023] Such as Figure 1-3 As shown in , the tension winch provides the loading function for the tested winch, and is connected with the tested winch by a cable. The tension winch can recover and release the rope, and make its speed automatically follow the tested winch, keeping the tension of the cable near the tension set by the user.

[0024] The hydraulic control system of the tension winch of the present invention comprises a small tension control circuit, a large tension control circuit, a cable discharge control circuit, a manual shift gearbox (9) and a cable reel (10);

[0025] The large tension control loop and the small tension control loop are switched and selected by the manual shift gearbox (9), and the cable drums (10) are respectively driven by the manual shift gearbox (9); the cable discharge control loop is controlled by the quantitative motor C (22) Drive the screw to drive the cable discharge mechanism to work;

[0026] The small tension control loop inclu...

Abstract

The invention discloses a hydraulic control system and a method of a tension winch. The tension winch provides a loading function to a tested winch, and is connected with the tested winch through a cable. The tension winch can recover and release a rope, and the speed automatically follows up the tested winch; and the tension of the cable is kept near the user set tension. A hydraulic system of the tension winch comprises a high-tension control loop, a low-tension control loop and a cable arrangement control loop. The hydraulic system adopts the low-tension control loop when set tension is lower, so that the low-tension control precision and the highest speed requirement are guaranteed; the high-tension control loop is adopted when the set tension is higher; a variable pump is controlled to automatically adapt to the speed of the tested winch so as to achieve the effect of energy conservation; and the cable arrangement control loop is associated with a proximity switch of a cable arrangement mechanism to achieve a cable arrangement effect.

Description

technical field [0001] The present invention relates to a hydraulic control system and method of a tension winch, and more specifically relates to a tension winch capable of switching between large and small tension modes, keeping the loading tension near the tension set by the user, and having certain energy-saving properties Hydraulic systems and methods thereof. Background technique [0002] The hydraulic system is a system that uses hydraulic oil as the working medium and works based on Pascal's principle. It is mainly composed of hydraulic pumps, hydraulic valves, hydraulic motors and accessories. A winch is an industrial equipment that uses a drum to wind a wire rope or chain to lift or pull heavy objects, also known as a hoist. Winch is widely used in mine hoisting, offshore equipment and other fields. The tension winch is a device that provides the cable load force for the tested winch. The rope of the tested winch is connected to the tension winch through the tur...
