Embodiment
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings.Following examples are merely to illustrate this hair
It is bright, it is not limited to protection scope of the present invention.
As shown in Fig. 3, Fig. 3 a, Fig. 3 b, a kind of improved manual for power hydraulic pressure disk brake of the invention discharges
Device, it includes base 1, operating cyloinder 3, piston rod A7, reinforcing pole socket 6, connecting rod 17, rotary support 4, operating cylinder 10, work
Stopper rod B13 and fuel tank 11,
Operating cyloinder 3 and operating cylinder 10 are both secured on base 1, and operating cyloinder 3 is connected to one by screw thread and base 1
Rise, coordinate between piston rod A7 and operating cyloinder 3 for gap, sealed by sealing ring B4, prevent hydraulic oil from leaking；Reinforcing
Connected between pole socket 6 and piston rod A7 by bearing pin B1, bearing pin B1 enters row constraint by pad B2 and split pin B3；Reinforce pole socket
6 are connected with connecting rod 17 by bearing pin, enter row constraint with pad B2 and split pin B3；Pass through pin between connecting rod 17 and rotary support 4
Axle B5 is attached, and enters row constraint with B2 pads and split pin B3；Rotary support 4 is enclosed on operating cyloinder 3, with lock washer 5
Above-below direction constraint is carried out with nut, circumferencial direction is without constraint；It is attached between operating cylinder 10 and base 1 with screw thread, it is living
Coordinate between stopper rod B13 and operating cylinder 10 for gap, installation sealing ring B4 is sealed hydraulic oil on piston rod B13, is prevented
Only hydraulic oil leaks；Spring 14 is installed on piston rod B13, in the case of without oil pressure, bullet that piston rod B13 passes through spring 14
Spring force acts on, in extreme lower position；Compressed between fuel tank 11 and base 1 by locking nut 12, contact portion encryption envelope
Circle B4 is sealed, and prevents hydraulic oil from leaking.
Oil circuit is turned between operating cyloinder 3 and fuel tank 11, has steel ball 8 to be obstructed among oil circuit, can unidirectionally be flowed
Logical, i.e., hydraulic oil can flow to operating cyloinder 3 from fuel tank 11；There is two-way oil circuit UNICOM between operating cylinder 10 and fuel tank 11, the
There is steel ball 8 to be obstructed among oil circuit all the way, can one-way flow, i.e. hydraulic oil can flow to operating cylinder 10 from fuel tank 11, this
Road steel ball 8 is compressed by off-load screw 18, can be turned on when unclamping the oil circuit of off-load screw 18, hydraulic oil can be from operating cylinder
10 flow to fuel tank 11；Second road binders routing safety magnetic valve 16 is obstructed, and security solenoid valve 16 is normally closed type, security solenoid valve
16 after electricity to that can turn on oil circuit, and hydraulic oil can flow to fuel tank 11 from operating cylinder 10；Security solenoid valve 16 by screw thread with
Base 1 is connected；Ye You oil circuits UNICOM between operating cyloinder 3 and operating cylinder 10, there is steel ball 8 to be obstructed among oil circuit, can be single
To circulation, i.e. hydraulic oil can flow to operating cylinder 10 from operating cyloinder 3.
Operative relationship：1st, pressurize：It is lifted up reinforcing pole socket 6 with boosting-rod, drives piston rod A7 to move upwards, by fuel tank
Hydraulic oil in 11 is drawn onto in operating cyloinder 3, is pressed down on reinforcing pole socket 6 with boosting-rod, is driven piston rod A7 to move downward, will
Hydraulic oil pressure in operating cyloinder 3 is in operating cylinder 10, and hydraulic oil rises in operating cylinder 10, and overcoming the resistance of spring 14 makes
Piston rod B13 is moved upwards；And so on operate, piston rod B13 can be made to move the position of needs upwards.
2nd, pressure release：Turn off-load screw 18, makes the distress resolves of compression steel ball 8, steel is made in the presence of hydraulic fluid pressure
Ball 8 turns on the oil circuit between fuel tank 11 and operating cylinder 10, it is 0 to make the oil pressure in operating cylinder 10, piston rod to left movement
B13 moves downward under the elastic force effect of spring 14, falls back to extreme lower position.
When forgetting to carry out pressure release using off-load screw 18, brake can be powered when starting shooting to security solenoid valve 16, safety
After magnetic valve 16 is powered, the oil circuit between ON operation oil cylinder 10 and fuel tank 11, it is 0 to make the oil pressure in operating cylinder 10, piston
Bar B13 moves downward under the elastic force effect of spring 14, falls back to extreme lower position.
360 ° of rotations of the center of operating cyloinder 3 progress can be surrounded by reinforcing pole socket 6.Operation principle is：Rotary support 4 is to be enclosed on behaviour
Make on oil cylinder 3, its up and down motion, but unconfined condition in a circumferential direction are limited by nut check, therefore rotary support 4 can be with
360 ° of rotations are carried out around the center of operating cyloinder 3, reinforcing pole socket 6 is connected by connecting rod 17 with rotary support 4, and piston rod A7 is in circle
All and upper and lower unconfined condition, can move up and down and rotate, and piston rod A7 is connected with reinforcing pole socket 6, so reinforcing pole socket 6 can enclose
360 ° of rotations are carried out around the center of operating cyloinder 3 and sternly piston rod axis direction can be moved up and down.Such a design solves reinforcing
The operation inconvenience that the position fixing band of pole socket 6 is come.
The operation principle of the improved manual release device of the present invention is piston rod A7 is transported upwards by operating reinforcing pole socket 6
It is dynamic, the hydraulic oil in fuel tank 11 is sucked in operating cyloinder 3 by oil circuit, then moved downward by piston rod A7 and lead to hydraulic oil
Cross oil circuit to be pressed into operating cylinder 10, as the increase of hydraulic oil rises piston rod B13, piston rod B13 directly acts on power
Onto apical ring 112, brake arm is opened.
After brake is opened, after completing maintenance or other tasks, after piston rod B13 now rises to certain position,
To ensure next brake energy normal work, it is necessary to which the pressure in operating cylinder 10 is reduced into 0, operation is now needed to rush down lotus screw
18, after loosening off-load screw, steel ball 8 in the presence of oil pressure, moves right again, makes the oil circuit between fuel tank 11 and operating cylinder 10
Conducting, makes the hydraulic oil in operating cylinder flow back in fuel tank 11, the pressure in operating cylinder 10 is reduced to 0 so that piston rod B13
Extreme lower position is returned to slowly under the spring-force driven dual of spring 14, ensures the normal work of brake.
When it will be 0 to forget operation off-load screw 18 by pressure in operating cylinder 10, start can be pacified when being powered to closed type
Full magnetic valve 16 is powered, and security solenoid valve 16 can turn on fuel tank 11 after being powered and is connected with the oil circuit of operating cylinder 10, now work
Hydraulic oil in oil cylinder 10 can be flowed into fuel tank 11 by the oil circuit of conducting so that the oil pressure in operating cylinder 10 is 0 so that living
Stopper rod B13 returns to extreme lower position slowly under the spring-force driven dual of spring 14, ensure that the safety of service braking.So safety
Magnetic valve 16 is avoided that after overhauling or powering off opening brake because forgeing the peace that the pressure in operating cylinder being reduced to 0 and being brought
Full hidden danger and accident.
The hand release of the present invention, can 360 ° of operations, and carry security solenoid valve, the position being assembled on brake
Put, as shown in Figure 3.The mechanism solves two big shortcomings of existing mechanism：
1. operating personnel can rotate to reinforcing pole socket the position for facilitating oneself to operate according to the operating space at scene,
Avoid the unhandy problem that band of position is fixedly mounted.
2. the device is equipped with electromagnetic valve, forget after maintenance or emergency power off opening brake by the pump housing
Oil pressure when being reduced to 0, after being powered up, electromagnetic valve can connect oil circuit, and the oil pressure allowed in the pump housing is let out as 0.Avoid because
Forgetting can not be braked caused by the oil pressure in the pump housing is reduced into 0 or the security incident because caused by can not brake.
