Abstract
The utility model discloses a disk floodgate stopper hydraulic control system, including driving the pneumatic cylinder for the nonoculture that disk floodgate stopper and brake disc leave, close to reach the hydraulic pump through electromotor drive, the oil inlet of hydraulic pump inserts in the oil tank, be equipped with the check valve on the pipeline in oil -out intercommunication hydraulic cylinder piston rod chamber for the nonoculture of hydraulic pump, check valve and be connected with the first loop for the nonoculture on the pipeline between the pneumatic cylinder, the first loop is in proper order through first solenoid valve, electric liquid overflow valve intercommunication oil tank. The electricity hydrorrhea flows valve control hydraulic cylinder piston rod chamber slow rising of pressure to be opened until maximum value disk floodgate stopper completely, and the hydraulic pump stops, keeping hydraulic cylinder piston rod chamber pressure under the effect of check valve, and the power that by a wide margin reduces the hydraulic pump is extravagant, can reduce the temperature of hydraulic oil moreover, improves the life of hydraulic pump.
Description
Technical field
The utility model relates to brake field, is specifically related to a kind of dish brake brake hydraulic Controlling System.
Background technology
Dish brake stopper utilizes the disk spring of single-action hydraulic cylinder for damping force, drives Block brake to rotate retarding disc mechanically, it is achieved the object of braking machinery. When machinery normally runs, disc braking device is in pine lock state, it is necessary to relying on the hydraulic pressure of single-action hydraulic cylinder to make every effort to overcome and take spring power, now hydro-pump is always in running order, owing to the working time of machinery is greatly more than braking time, cause the significant wastage of hydro-pump power.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of dish brake brake hydraulic Controlling System, existing dish brake stopper can be solved in the pine lock state hydro-pump in running order spring power to overcome single-action hydraulic cylinder always, cause the problem causing the significant wastage of hydro-pump power.
The utility model is achieved through the following technical solutions:
A kind of dish brake brake hydraulic Controlling System, comprise disc-shaped lock stopper and retarding disc from, the single-action hydraulic cylinder that closes, and by hydro-pump that electric motor drives, in the oil-in insertion fuel tank of described hydro-pump, the pipeline that the oil outlet of described hydro-pump is connected single-action hydraulic cylinder piston rod chamber is provided with check valve, being connected with the first loop on pipeline between described check valve and single-action hydraulic cylinder, described first loop is connected fuel tank through the first magnetic valve, electro-hydraulic surplus valve successively.
Further scheme of the present utility model also comprises the second servo loop in parallel with the first loop, and described second servo loop is connected fuel tank through energy storage, the 2nd magnetic valve successively.
Further scheme of the present utility model is connected with the used oil pipe being connected fuel tank on the pipeline between described hydro-pump and check valve, and described used oil pipe is provided with surplus valve.
The utility model advantage compared with prior art is:
One, electro-hydraulic surplus valve hydraulic control cylinder piston rod cavity pressure slowly raises until maximum value dish brake stopper is opened completely, hydro-pump stops, hydraulic cylinder piston rod cavity pressure is kept under the effect of check valve, the power dissipation of much slower hydro-pump, and the temperature of hydraulic efficiency oil can be reduced, it is to increase the work-ing life of hydro-pump;
Two, energy storage can carry out ftercompction when hydraulic efficiency system exists and reveals, and shortens the working time of hydro-pump, reduces energy consumption further.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
A kind of dish brake brake hydraulic Controlling System as shown in Figure 1, comprise disc-shaped lock stopper 8 and retarding disc 9 from, the single-action hydraulic cylinder 7 closed, and by hydro-pump 4 that electric motor 3 drives, in the oil-in insertion fuel tank 1 of described hydro-pump 4, the pipeline that the oil outlet of described hydro-pump 4 is connected single-action hydraulic cylinder 7 piston rod chamber is provided with check valve 6, pipeline between described check valve 6 and single-action hydraulic cylinder 7 is parallel with the first loop and second servo loop, described first loop is successively through the first magnetic valve 13, electro-hydraulic surplus valve 15 is connected fuel tank 1, described second servo loop is successively through energy storage 12, 2nd magnetic valve 14 is connected fuel tank 1, pipeline between described hydro-pump 4 and check valve 6 is connected with the used oil pipe being connected fuel tank 1, described used oil pipe is provided with surplus valve 5.
When rotating mechanically activated pine lock, electric motor 3 drives hydro-pump 4 to work, 2nd magnetic valve 14 turns off and second servo loop is ended, first magnetic valve 13 is opened and is made the first loop conducting, hydraulic efficiency oil is through check valve 6, a part enters the piston rod chamber of single-action hydraulic cylinder 7, some enters energy storage 12, residue part flows back to fuel tank 1 through electro-hydraulic surplus valve 15, under the adjustment of electro-hydraulic surplus valve 15, the pressure in the piston rod chamber of single-action hydraulic cylinder 7 raises until pressure reaches maximum value gradually, dish brake stopper 8 is driven to be separated gradually with retarding disc 9 until opening completely, rotate machinery and enter normal operation state, then the first magnetic valve 13 turns off, electric motor 3 and hydro-pump 4 stop, enter packing state, when the pressure that the piston rod chamber causing single-action hydraulic cylinder 7 is revealed in hydraulic efficiency system existence reduces gradually, energy storage 12 output hydraulic pressure oil realizes ftercompction, to shorten electric motor 3 and the working time of hydro-pump 4, when pressure drop is to, when rotating the mechanical Schwellenwert normally run, electric motor 3 and hydro-pump 4 again start and carry out ftercompction until reaching Pressure maximum value.
When rotating mechanical braking, first magnetic valve 13 is opened, hydraulic efficiency oil slowly flows back to fuel tank 1 under the effect of electro-hydraulic surplus valve 15, realize dish brake stopper 8 slowly contacts until rotating machinery and braking completely with retarding disc 9, first magnetic valve 13 and electro-hydraulic surplus valve 15 turn off simultaneously, hydraulic efficiency system stopping work.
