Abstract
The utility model discloses a reverse hydraulic brake mechanism for a screw pump driving device and belongs to clutches or brakes. The reverse hydraulic brake mechanism consists of a spindle, a hydraulic pump and a brake caliper, wherein a brake disc, a transmission gear and a clutch are concentrically fixed on the spindle; the transmission gear on the spindle is meshed with a driving gear on the hydraulic pump; the hydraulic pump is connected with the brake caliper through a hydraulic oil way; a caliper opening of the brake caliper hooks the brake disc; the clutch is divided into a pawl and a ratchet wheel; the pawl is fixed on the spindle through a hinge; the ratchet wheel is in concentric clearance fit with the spindle; and the ratchet wheel and the transmission gear are integrated. The reverse hydraulic brake mechanism for the screw pump driving device is reasonable in structural design and accurate in operation, and is stable, safe and reliable; and moreover, the program is easily and automatically controlled, the working efficiency is improved, the mechanical equipment is effectively prevented from being damaged, and the service life of the device is prolonged.
Description
Technical field
The utility model belongs to clutch or break, particularly driving unit on screw pump counter-rotating hydraulic brake mechanism.
Background technique
Mechanical rotary device, when stopping to drive, the mechanical energy that system continues 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 its elongated transmission power has been put aside higher reverse elasticity energy like oil pumping screw pump.When driving stopped, this huge reverse elasticity energy was released, and ordered about drive unit high-speed reverse rotation, very easily caused the damage of transmission device or human injury took place or make sucker rod connecting thread button get loose, crash into the down-hole, caused 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 overcome the deficiency of existing technology, and a kind of driving unit on screw pump counter-rotating hydraulic brake mechanism is provided.
The driving unit on screw pump counter-rotating hydraulic brake mechanism of the utility model; Be to constitute by main shaft, oil hydraulic pump and braking clamp; Coaxial heart is fixed with brake disc, driving gear and clutch on main shaft; Driving gear on the main shaft is meshed with actuation gear on the oil hydraulic pump, and oil hydraulic pump links to each other through hydraulic circuit with braking clamp, and the jaw rank of braking clamp is lived brake disc.
As the further improvement of the utility model, described clutch is divided into pawl-and-gearing, and on the main shaft, the concentric Spielpassung of ratchet is on main shaft through hinges fixing for ratchet, and ratchet and driving gear are one.
Further improvement as the utility model is provided with brake block on braking clamp.
As the further improvement of the utility model, hydraulic pump block is on frame.
The driving unit on screw pump counter-rotating hydraulic brake mechanism of the utility model, reasonable in design, accurate, stable, the safety, reliable of operation.The program of easily being automated is controlled, and has improved working efficiency, has protected machinery to be without prejudice effectively, has improved device working life.
Description of drawings
Fig. 1 is the utility model existing technology structural representation;
1 main shaft, 2 oil hydraulic pumps, 3 braking clamps, 4 brake discs, 5 hydraulic circuits, 6 fixing frames, 7 driving gears, 8 actuation gears, 9 brake blocks, 10 ratchets, 11 ratchets, 12 clutches, 13 hinges among the figure.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified:
The driving unit on screw pump of the utility model counter-rotating hydraulic brake mechanism is to be made up of main shaft 1, oil hydraulic pump 2 and braking clamp 3, and 2 of oil hydraulic pumps are on frame 6.Coaxial heart is fixed with brake disc 4, driving gear 7 and clutch 12 on main shaft 1; Driving gear 7 on the main shaft 1 is meshed with actuation gear 8 on the oil hydraulic pump 2; Oil hydraulic pump 2 links to each other through hydraulic circuit 5 with braking clamp 3; The jaw rank of braking clamp 3 is lived brake disc 4, on braking clamp 3, is provided with brake block 9.
Described clutch 12 is divided into ratchet 10 and ratchet 11, and ratchet 10 is fixed on the main shaft through hinge 13, and the concentric Spielpassung of ratchet 11 is on main shaft 1, and ratchet 11 is an one with driving gear 7.
The driving unit on screw pump counter-rotating hydraulic brake mechanism of the utility model when the main shaft backward rotation, drives ratchet ratchet and driving gear is rotated; Also and then rotate with the actuation gear of driving gear engagement; Drive oil hydraulic pump, braking clamp is clamped, make jaw apply braking force brake disc through hydraulic circuit; To prevent the quick counter-rotating of sucker rod, realized the flexibility brake of device.This not only makes device be effectively protected, and the release that puts on reverse elasticity power of this braking force, can both obtain sensitivity, accurate match.Not only simplify the device structure of existing apparatus, also need not other control system.
