Embodiment Construction

[0009] The present invention will be described in further detail below in conjunction with accompanying drawing:

[0010] The inclined plane disc brake of the winch is mainly composed of a brake disc, a brake block, a dynamic inclined plane, a static inclined plane, and a telescopic cylinder. The telescopic cylinder can drive the dynamic inclined plane to move up and down. Such as figure 1 shown.

[0011] exist figure 2 Among them, A1 and A2 are a pair of brake blocks, B1 and B2 are a pair of dynamic slopes on which the brake blocks are fastened, C1 and C2 are a pair of static slopes that are fixed, and D is a brake disc. When the telescopic cylinder gets the brake signal, the cylinder quickly deflates, the spring in the cylinder pushes the piston up, and the telescopic rod of the cylinder pulls one end of the lever to move up, so that the moving slope at the other end receives the thrust of Fb1, Fb2, and moves down along the static slope, and the brake block A1 and A2 are...

Abstract

The invention relates to a parking brake of a winch, which can used as the main brake of the winch and is used in petroleum drilling industry. The parking brake has self-braking function and does not need an external braking power source, so as to omit hydraulic pressure stations, hydraulic valves, pipelines, hydraulic operating pliers, etc. used in a conventional hydraulic disc brake. The inclined disc brake is mainly composed of a brake disc, a brake block, a mobile inclined plane, a stationary inclined plane, a telescopic cylinder, etc. The inventive inclined disc brake has the advantages of simple structure, convenient control, good braking effect, and safe and reliable performance.

Description

technical field [0001] The invention is mainly used for the parking brake of the drawworks, can be used as the main brake of the drawworks, and is applied in the oil drilling industry. Background technique [0002] At present, the main brake of oil drilling winch usually adopts traditional band brake and hydraulic disc brake. The band brake system is a mechanical lever brake mechanism. The hydraulic disc brake device is mainly composed of hydraulic control part and hydraulic brake caliper. Compared with belt brakes, hydraulic disc brakes have large braking torque capacity, stable braking performance, accurate and sensitive braking, and easy operation. The disadvantage is that the braking control part is complicated, and the braking process requires a hydraulic power source. The power source is large and occupies the limited precious space on the drill floor, while the inclined disc brake has no power source, energy saving, small size and simple structure. , low cost, excell...
