Embodiment Construction

[0010] As shown in the figure, the structural principle of a dual-control film type air-controlled brake. Including manual double control valve 2, normally closed brake controller 3, normally open brake controller 4, normally open brake film cylinder 5, normally closed brake film cylinder 6, brake spring 7, normally closed cylinder piston rod 8, normally open cylinder Piston rod 9, brake output shaft 10, coupling 11, winch brake handle shaft 12, winch brake shaft 13, winch brake band 14, winch brake hub 15, winch drum 16 etc. are formed. Connect as shown in the figure. Its control method is as follows: compressed air is input from the air source input port 1, and after passing through the manual double-connected control valve 2, two complementary pressure-regulating control airs are output, and the pressure-regulating air is respectively passed through the respective brake controllers (3 and 4). The signal is amplified, and then the normally open brake membrane cylinder 5 and...

Abstract

The invention belongs to an air control brake control method for a dual-control membrane type drilling machine in the technical field of petroleum drilling machine control. Compressed air is output through a manual duplex control valve into two paths of complementary pressure-regulating control air to respectively control a normally closed brake controller and a normally open brake controller, a pressure regulating air signal is amplified to respectively control a normally open brake membrane cylinder and a normally closed brake membrane cylinder, and under the coefficient power, through driving a brake crank shaft and a brake shaft of a winch by respective piston rods of the two cylinders, a brake output shaft, and a coupling, a brake band and a brake hub are enclasped to realize winch barrel braking. The air control brake control method and system has the advantages that the brake torque is large, and the brake torque of a winch is increased by one time through the combined action of the normally open brake membrane cylinder and the normally closed brake membrane cylinder. The braking is safe and reliable, and even if a control part is totally failed, a winch barrel can be firmly braked by a brake spring.

Description

technical field [0001] The invention belongs to the technical field of oil drilling equipment, in particular to a control system of an oil drilling rig. Background technique [0002] The traditional oil drilling rig drawworks use the driller to manipulate the winch brake handle to control the lowering speed of the hook of the traveling car. The labor intensity of the driller is high and the working environment is very harsh. [0003] According to retrieval, Chinese invention patent (CN2409101Y) discloses a kind of winch brake controller, and its main technical feature is to be provided with oil cylinder and air cylinder on the cylinder body that is formed by the cylinder block seat of cylinder head, and oil cylinder and air cylinder share a piston pole. A spring box is arranged between the cylinder and the crankshaft, and a connecting rod and a return spring are arranged in the spring box. One end of the connecting rod is rotatably connected with the crankshaft, and the oth...
