Referring to fig. 1 and 2, the gas-liquid disc brake device for the drilling and workover rig comprises a brake gas-liquid control system, wherein a single-sided brake disc 8 is arranged at one end of a winch drum shaft, a set of safety brake caliper 1 and two sets of working brake calipers 3 are arranged corresponding to the single-sided brake disc 8, and the safety brake caliper 1 and the two sets of working brake calipers 3 are both connected with a gas-liquid boosting cylinder 12.
The brake gas-liquid control system comprises an automobile gas storage cylinder 20, a gas source processing combination device 21 and a gas circuit board 19 which are connected in sequence; the emergency button valve 15, the normally open valve 16 and the manual control valve 18 are directly communicated and connected with the gas circuit board 19; a shuttle valve 17 is connected between the normal-pressure valve 16 and the manual control valve 18, and the shuttle valve 17 is sequentially connected with the gas-liquid boosting cylinder 12 and the working brake caliper hydraulic cylinder 9; the emergency button valve 15 and the normally open valve 16 are connected with the manual reversing valve 14 after being connected in tandem, and the manual reversing valve 14 is sequentially connected with the gas-liquid boosting cylinder 12 and the safety brake caliper hydraulic cylinder 10.
One end of the winch drum body 7 is provided with a clutch 5 and a chain transmission assembly 6, the other end of the winch drum body is fixedly provided with a brake disc 8 on a drum shaft, and the brake caliper seat 4 is fixedly arranged on the frame. The reservoir 11 and the gas-liquid booster cylinder 12 (2 pieces each) are installed near the winch. The pressure gauge 13, the manual reversing valve 14, the emergency button valve 15 and the manual valve 18 are arranged on the driller console.
In the braking control, a pneumatic control valve controls a pneumatic-hydraulic boosting cylinder 12 to pressurize and inject pressure oil into a hydraulic cylinder of the brake caliper to enable the hydraulic cylinder to stretch, and then a lever acts on the brake pad 2 (6 pieces) to enable the brake pad 2 to press a brake disc to achieve braking of the winch drum.
During operation, the clutch 5 is closed, and the diesel engine power drives the roller body 7 to rotate through the chain transmission assembly 6 so as to carry out the tripping operation of the pipe column. The safety brake caliper 1 and the working brake caliper 3 are fixed on the caliper seat 4, and the caliper seat 4 is fixed on the frame to bear the braking force.

Emergency state: when the emergency button valve 15 is pressed, the loop air pressure of the safety brake caliper 1 returns to 0, and the spring brakes. And simultaneously, the normal-time valve 16 is reset, and compressed air enters the pneumatic-hydraulic boosting cylinder 12 of the working brake caliper 3 for braking through the normal-time valve 16 and the shuttle valve 17, so that the safety brake caliper 1 and the working brake caliper 3 perform synchronous braking.
The main technical parameters are as follows: rated hook load: 400 kN.
Maximum hook load: 700 kN.
Maximum lifting speed of the hook: 1.5 m/s.
