Abstract
The utility model belongs to a double-control film-type drilling machine pneumatic-control braking system in the field of petroleum drilling machine control technology. The double-control film-type drilling machine pneumatic-control braking system is provided with a manual duplex control valve connected with an air source input port, the manual duplex control valve outputs two ways of complementary pressure-adjusting control air to be respectively led into and control a normally closed braking controller and a normally open braking controller, the normally closed braking controller and the normally open braking controller are respectively connected into a normally closed braking film air cylinder and a normally open braking film air cylinder, the normally closed braking film air cylinder and the normally open braking film air cylinder are connected on a braking output shaft through respective piston rod lower ends, the braking output shaft is connected with a winch braking handle shaft through a coupling, and the winch braking handle shaft is connected with a braking shaft under a winch braking drum. The double-control film-type drilling machine pneumatic-control braking system has the advantages that braking moment is large, common action of the normally closed braking film air cylinder and the normally open braking film air cylinder is adopted, the braking moment of a winch is doubled, braking is safe and reliable, and even when a control part completely fails, a braking spring can firmly brake a winch rotary drum.
Description
Technical field
The utility model belongs to the control system of oil drilling equipment technical field, particularly oil-well rig.
Background technology
Traditional petroleum drilling machine winch all adopts the driller to handle winch brake the hook block lowering velocity is controlled, and driller's labour intensity is big, and working environment is very abominable.
According to retrieval, Chinese utility model patent (CN2409101Y) discloses a kind of winch brake controller, and its major technique feature is to be provided with oil cylinder and cylinder at the cylinder body that the cylinder block by the cylinder body lid constitutes, and oil cylinder and cylinder share a piston rod.Be provided with spring box between cylinder and bent axle, be provided with connecting rod and retracing spring in the spring box, connecting rod one end and bent axle are rotationally connected, and the other end and piston rod are collided and connect.It is moving to realize that in use aspect oil-well rig and the service machine gas control or hydraulic control reach remote control control, but the structure more complicated, the cost height.
In order to improve described deficiency, the utility model people has proposed a kind of petroleum drilling winch gas control brake actr (CN02262095.8) and has comprised casing, be provided with in the casing (1) and often open cylinder and normally closed cylinder, the air cylinder connecting rod of often opening cylinder and normally closed cylinder is connected with public output shaft by crank throw respectively, be with brake spring on the air cylinder connecting rod of normally closed cylinder, the lower end of brake spring is fixed on the casing, and the upper end is fixed on the air cylinder connecting rod.Can realize that the driller is to the distance control of well drilling winch brake, it is free and relaxed that the driller is operated, and alleviated driller's labour intensity, improved driller's working environment, improve work safety and the personal safety of rig, improved the automatic control level of oil-well rig.But this formerly patent just provided actuating unit, how better to realize for the control part of this actuating unit, do not provide technical scheme.
The utility model content
The utility model purpose provides a kind of two control diaphragm type rig gas control brake system, to satisfy the boring winch Long-distance Control.
Two control diaphragm type rig gas control brake system, it is characterized in that having the manual duplex control cock that links to each other with the source of the gas input port, the pressure-regulating control air of described manual duplex control cock output two-way complementation feeds the normally closed brake controller of control and Chang Kai brake controller respectively, described normally closed brake controller and Chang Kai brake controller insert normally closed brake film cylinder and Chang Kai brake film cylinder by gas circuit respectively, normally closed brake film cylinder and often open the piston-rod lower end of brake film cylinder by separately and be connected on the brake output shaft, the brake output shaft is connected with winch brake lever axle by plunging joint, and winch brake lever axle is connected with the brake axle that is positioned at Jiao car Sha Che Grains bottom.On the normally closed cylinder piston rod of normally closed brake film cylinder brake spring is housed.
The advantage of this utility model is: 1, brake torque is big, has adopted the combined action of often opening brake diaphragm cylinder and normally closed brake diaphragm cylinder, and the brake torque of winch is doubled.2, brake is safe and reliable, even control part all breaks down, brake spring also can firmly be stopped winch drum extremely.3, highly sensitive, adopt the diaphragm type brake cylinder, be active in one's movements, delay time is short, has improved the steerability energy of operation greatly.4, easy to maintenance, the gas control element is durable, easily maintenance.5, atmosphere free from environmental pollution, that the atmosphere that air is got is put does not have any pollution to environment.
Description of drawings
Figure is the utility model principle schematic.
The specific embodiment
As shown in the figure, the structural principle of a kind of two control diaphragm type gas control brake.Comprise manual duplex control cock 2, normally closed brake controller 3, often open brake controller 4, often open brake film cylinder 5, normally closed brake film cylinder 6, brake spring 7, normally closed cylinder piston rod 8, often open compositions such as cylinder piston rod 9, brake output shaft 10, plunging joint 11, winch brake lever axle 12, winch brake axle 13, winch brake strap 14, Jiao car Sha Che Grains 15, winch drum 16.Get final product according to connecting as shown in the figure.Its control method is: pressurized air is from 1 input of source of the gas input port, the pressure-regulating control air of output two-way complementation after manual duplex control cock 2, the brake controller (3 and 4) that passes through separately amplifies pressure regulation gas signal respectively, brake film cylinder 5 and normally closed brake film cylinder 6 are often opened in control respectively again, the power of two cylinder generations drives brake lever axle 12 and the brake axle 13 of winches by piston rod (8 and 9), brake output shaft 10 and plunging joint 11 separately, winch brake strap 14 and Jiao car Sha Che Grains 15 are held tightly, thereby reach the purpose of winch drum 16 brakes.
Keystone configuration principle of the present utility model is: pressurized air is from 1 input of source of the gas input port, the pressure-regulating control air of output two-way complementation after manual duplex control cock 2, the brake controller (3 and 4) that passes through separately amplifies pressure regulation gas signal respectively, brake film cylinder 5 and normally closed brake film cylinder 6 are often opened in control respectively again, the power of two cylinder generations passes through piston rod (8 and 9) separately, brake output shaft 10 and plunging joint 11 drive brake lever axle 12 and the brake axle 13 of winch, winch brake strap 14 and Jiao car Sha Che Grains 15 are held tightly, thereby reach the purpose of winch drum 16 brakes.
It can be used for the control of the winch brake of oil-well rig, water drilling rig, coal mine drilling machine the utility model, be to replace a kind of novel control form that old-fashioned brake lever is operated and the hydraulic pressure dish is stopped and operated, safety, reliability, operability, maintainability that boring winch is braked all improve a lot.
