Abstract
The built-in hydraulic disc type braking device for screw pump driving head pertains to clutches or brakes. A hydraulic brake clip is fixed on housing of the reduction gear box, the vice jaw holding the brake disc fixed on the main shaft. Inner housing of the reduction gear box is provided fixedly with a hydraulic oil pump, hydraulic efferent of which connects with the hydraulic clip; a gear on the main shaft engages into the gear on output shaft of the hydraulic oil pump. The utility model has the advantages of simple structure as well as accurate, steady, safe and reliable operation. Automatic programmed manipulation can be easily realized, improving the working efficiency, protecting effectively the mechanical equipment against damages and prolonging the useful life thereof.
Description
Technical field
The utility model belongs to clutch or break, the built-in hydraulic disc brake device of particularly a kind of screw pump driving head.
Background technique
Mechanical rotary device, when stopping to drive, the mechanical energy of system's savings will discharge, and normally converse output energy orders about the mechanical device counterrotating, and this phenomenon is harmful to often.In the oil recovery operation process, the sucker rod of the transmission power that it is elongated has been put aside higher reverse elasticity energy as oil pumping screw pump.When driving stops, this huge reverse elasticity energy is released, order about drive unit high-speed reverse rotation, very easily cause the damage of transmission device or human injury takes place or make sucker rod connecting thread back-off get loose, crash into the down-hole, cause the oil well accident to stop production.Though there is similar anti-reverse braking device to be employed aborning, its structure is numerous and jumbled relatively, the reaction is sensitive and accurate inadequately, be difficult to control.
Summary of the invention
The utility model is intended to solve the deficiencies in the prior art, has designed a kind of braking device.Its design proposal is: water brake clamps by fixing on the housing of speed reducer, jaw is being held in the mouth the brake disc that is fixed on the main shaft and constituted.The design's improvement is to have fixedly mounted hydraulic-pressure pump on the inner housing of speed reducer, and the gear on the main shaft is meshed the hydraulic pressure output tube of hydraulic-pressure pump and water brake clipper joint with gear on the hydraulic-pressure pump input shaft.
The built-in hydraulic disc brake device of screw pump driving head of the present utility model, when the driving of speed reducer is stopped, its main shaft is owing to the release of the reverse elasticity energy of sucker rod savings is reversed, this counter-rotating is by gear driven oil hydraulic pump output oil pressure, conduct to hydraulic tongs through hydraulic tube again, make jaw apply braking force,, realized the flexibility brake of device to prevent the quick counter-rotating of sucker rod to brake disc.Design proposal of the present utility model is to utilize the release of the reverse elasticity power that rotating machinery produces to prevent the reverse high speed rotating of device.This not only makes device be effectively protected, and this braking force apply release with reverse elasticity power, can both obtain sensitivity, accurate match.Not only simplify the device structure of existing apparatus, also need not other control system.Present design middle gear pump-unit can be designed as outer gearing mekydro pump structure, also can be designed to the inside engaged gear pump structure.The safety that the built-in hydraulic disc brake startup of present design is sensitive, accurate, the anti-reverse effect of the dynamics that applies is reliable, guaranteed machinery also can reduce equipment investment and operating cost.
The built-in hydraulic disc brake device of screw pump driving head of the present utility model; project organization is simple, operation is accurate, stable, safety, reliable, and the program of easily being automated is controlled, and has improved working efficiency; protect machinery to be without prejudice effectively, improved working life.
Description of drawings
Figure of description is the structural representation of the built-in hydraulic disc brake device of the utility model screw pump driving head.
