The specific embodiment
Further describe below in conjunction with the specific embodiment of accompanying drawing the utility model.
Illustrated in figures 1 and 2 is the utility model hydraulic windlass; Comprise HM Hydraulic Motor 1, coupler 2, drive link 3, brake assemblies 4 and support 5; The output shaft of said HM Hydraulic Motor 1 connects said drive link 3 through said coupler 2; Said HM Hydraulic Motor 1 is fixed on the said support 5 through subpanel 6, and said brake assemblies is located in the said subpanel 6, and said brake assemblies comprises brake facing group 41, pressure disc 42 and disk spring 43; Be provided with independently oil pocket 61 and cavity 62 between one side of said pressure disc 42 and the inboard of said subpanel 6; Said brake facing group 41 is located in the said cavity 62, and the center of said brake facing group 41 is provided with hexagonal hole, and the part that said coupler 2 is positioned at said cavity 62 is a hexa-prism; Said brake facing group 41 is passed through the hexagonal hole socket with said coupler 2; Said disk spring 43 is located at the opposite side of said pressure disc 42 and inconsistent with the end face of said support 5, and the fuel-feed system of said HM Hydraulic Motor 1 comprises that through two oil circuits bonded assembly fuel tank 7 successively, three position four-way electromagnetic valve 8 and shuttle valve 9, the pressure hydraulic fluid port of said shuttle valve 9 is communicated with said oil pocket 61 through oil pipe.Two actuator ports of said shuttle valve 9 connect said HM Hydraulic Motor 1 through two balance cocks 10 respectively, and shuttle valve 9 and two balance cocks 10 are formed a valve piece 11.Be provided with y-shaped ring 611 in the said oil pocket 61.
Balance cock is also claimed speed limiting lock, is a kind of external control internal drainage type one way sequence valve, is also used by a check valve and a sequence valve together; In the hydraulic circuit; Can the locking hydraulic actuating cylinder or the motor oil circuit in fluid, make hydraulic actuating cylinder or motor can not glide Lock effect this moment because of the load deadweight.When hydraulic actuating cylinder or motor need move, through to the logical liquid of another oil circuit, open through balance cock internal oil passages control sequence valve simultaneously the loop is connected, realize its motion.Owing to when work, in the work loop, set up certain back pressure, be unlikely to make the main work of hydraulic actuating cylinder or motor produce negative pressure because of the deadweight hypervelocity glides, shock and vibration can not take place therefore.
The hydraulic circuit principle of work: the drag operation of capstan winch is accomplished by a big torque fluid motor-driven capstan winch.The rotating of HM Hydraulic Motor is controlled by a three position four-way electromagnetic valve.Be provided with balance cock in the loop, glide because of deadweight in order to prevent load.Because HM Hydraulic Motor has certain internal leakage, when load was parked in midway, although be provided with balance cock in the loop, weight is slip downwards still, for this reason, on the axle drive shaft of HM Hydraulic Motor, was provided with brake assemblies.When capstan winch was worked, under the effect of system oil pressure, brake facing unclamped, and when HM Hydraulic Motor stopped operating, under the effect of disk spring, brake facing was braked the axle locking.
As shown in Figure 2, oil pump 12 begins fuel feeding under the drive of motor.When electromagnetic valve does not move, be in meta, to fuel tank, do not work by capstan winch through electromagnetic valve P mouth, the oil return of T mouth for hydraulic oil.
Electromagnetic valve left side coil gets; Electromagnetic valve P mouth leads to the logical valve piece A mouth of valve piece B mouth, T mouth, and hydraulic oil arrives HM Hydraulic Motor through the check valve of B mouth, right side balance cock, simultaneously through the oil pocket (be equivalent to an oil cylinder) of shuttle valve in the brake assemblies; When oil circuit pressure reaches the brake response pressure earlier; Oil cylinder promotes disk spring, and the brake facing pre-pressing force discharges, and brake is opened; When oil circuit pressure continues to rise to balance cock outside control mouth control presssure (balance cock response pressure), left side balance cock hydraulic fluid port is opened, and the loop forms path, and hydraulic oil is turned round after get back to fuel tank by A mouth, T mouth to the C1 CD-ROM drive motor by C2.
Electromagnetic valve right side coil gets; Electromagnetic valve P mouth leads to the logical valve piece B mouth of valve piece A mouth, T mouth, and hydraulic oil arrives HM Hydraulic Motor through the check valve of A mouth, left side balance cock, simultaneously through the oil pocket (be equivalent to an oil cylinder) of shuttle valve in the brake assemblies; When oil circuit pressure reaches the brake response pressure earlier; Oil cylinder promotes disk spring, and the brake facing pre-pressing force discharges, and brake is opened; When oil circuit pressure continues to rise to balance cock outside control mouth control presssure (balance cock response pressure), right side balance cock hydraulic fluid port is opened, and the loop forms path, and hydraulic oil is turned round after get back to fuel tank by B mouth, T mouth to the C2 CD-ROM drive motor by C1.
During the capstan winch running; Hydraulic oil gets into the oil inlet and outlet of valve block assembly, and hydraulic pressure reaches the response pressure of brake assemblies earlier, through valve block assembly in-to-in shuttle valve; Hydraulic oil promotes y-shaped ring 611, pressure disc 42, disk spring 43; Make 41 no precompressed compressions of brake facing group, and can not produce friction drag, brake is opened fully.When hydraulic fluid pressure reached balance cock response pressure value, the balance cock valve port was opened, and the hydraulic oil CD-ROM drive motor rotates, and motor output shaft drives coupler 2, and then drove speed reduction gearing and load.
When capstan winch shut down, hydraulic oil source stop control lever, hydraulic fluid pressure were zero, and motor shuts down; Y-shaped ring 611, pressure disc 42 compress 41 of brake facing groups under the effect of disk spring 43, produce precompressed compression, if when load has heterodromous trend, the static friction force that the brake facing group is 41 produces braking effect, and load can not be moved.
The brake structure that the utility model adopts the video disc brake to combine with hydraulic pressure, in the braking of motor output shaft end, brake torque is big, and is safe and reliable; And be bi-directional braking; During the capstan winch running, motor driven, braking mechanism is opened fully, no power waste, efficient is high; Configuration balance cock piece connects compact conformation, capstan winch dynamic load good stability with brake structure with motor.
