Problems solved by technology

[0004] 2. The speed regulating gate and the working gate are completed by manual manipulation of the operating handle, the operating force is large, and long-term work is tiring, and its operating performance has a lot to do with the proficiency of people;
[0005] 3. The winch itself can only achieve overwinding protection, and various protections are realized by backup protection devices. Therefore, the National Safety Standards Office terminated the safety standard of JTKB-1.2 block brake hoisting winch in June 2010;
[0006] 4. During the speed regulation process, the brake pads on the brake block wear quickly, and it is difficult to find the clutch point during the speed regulation, so it is impossible to achieve the required speed to not only make the winch run slowly, but also lift the heavy objects to the maximum good condition

Abstract

The invention relates to the technical field of mining hoisting winches and discloses a novel mechanical speed-regulating mining hoisting winch electro-hydraulic integrated control device for controlling a mining hoisting winch provided with a disc-shaped speed-regulating brake and a disc-shaped brake. The electro-hydraulic integrated control device comprises an explosion-proof hydraulic station providing pressure oil to the disc-shaped speed-regulating brake and the disc-shaped brake through two independent oil ways respectively, and an explosion-proof main control console controlling the work of the explosion-proof hydraulic station. The electro-hydraulic integrated control device enables the operating speed of a mine car to be low and can lift a heavy object to be in an optimal state when achieving starting speed required by the winch, and is safe in stopping and reliable in braking.

Description

technical field [0001] The invention relates to the technical field of mine hoisting winches, and more specifically relates to a novel mechanical speed-regulating mine hoisting winch machine, electric and hydraulic integrated control device. Background technique [0002] At present, the integrated JTKB-1.2 mine hoisting winch adopts block type speed regulation and braking. Mechanical block type braking is used to realize the start, operation and stop of the winch. The winch itself only has overwinding protection, and other protections rely on backup. protector to achieve. Its disadvantages are: [0003] 1. The safety brake adopts block brake, and the braking force depends on the weight of the counterweight; [0004] 2. The speed regulating gate and the working gate are completed by manual manipulation of the operating handle, the operating force is large, and long-term work is tiring, and its operating performance has a lot to do with the proficiency of people; [0005] 3...
