Vehicle control valve group 8, guide's brake control valve 9, ball valve 10, water brake brake 11, turntable motor 12 constitute brake control oil
Road, guide's brake control valve 9 are connect with pressure reducing valve 4.
After the pressure oil of fuel tank enters hydraulic pump 1, the pressure oil of hydraulic pump 1 passes through main overflow valve 2, proportional reversing valve 6, puts down
Weigh and reach turntable motor 12 after valve 7, return to fuel tank, self-actuating brake unit automatic un-brake at work, by pilot control valve 3,
Proportional reversing valve 6 jointly controls the torque running speed and steering of turntable motor 12, realizes the positive and negative rotation and speed of turntable motor 12
It adjusts；7 working hole of balanced valve is connected on the rotating forward circuit of turntable motor 12, when turntable motor 12 during rotating forward by prominent
Hair-like condition, which generates reverse impact, causes turntable motor 12 when the generation of rotating forward process is inverted trend, due to 7 pilot port 3 of balanced valve
Without guide oil, 7 internal sequence spool of balanced valve is closed, and pressure oil can not flow back, and the reversion of turntable motor 12 is prevented to occur；Guide
Brake control valve 9 has control function of going beyond one's commission, and no matter which kind of state turntable motor 12 is in, can operated pilot brake control
Valve 9 controls turntable motor 12 and brakes.
Brake control valve group 8 is made of differential spool, relief pressure valve cartridge, steering of surging spool and nonreturn valve core.
The utility model has the advantages that compared with prior art:
1, the accurate control for realizing snubbing serving equipment rotary speed passes through the self-actuating brake function of turntable hydraulic system
Can, snubbing serving equipment may be implemented when carrying out the operations such as brill plug, milling to the accurate control of rotary speed；
2, the emergency brake and turntable reverse-rotation preventing function for realizing hydraulic swivel head, pass through the balanced valve control of turntable hydraulic system
System can prevent turntable anti-when turntable is generated reverse impact by emergency situations during rotating forward, and motor is caused to be inverted
The generation turned；And when operator's maloperation or hydraulic system break down, operator can be stopped by operated pilot
Vehicle valve is gone beyond one's commission control, and turntable is braked in directly brake, prevents safety accident.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
Specific embodiment
The utility model will be further described with reference to the accompanying drawings and embodiments.
Referring to Fig. 1, the power control unit of the utility model includes hydraulic pump 1, main overflow valve 2, pilot control valve 3, subtracts
Pressure valve 4, ratio change-over pilot valve 5, proportional reversing valve 6, balanced valve 7, turntable motor 12 are concatenated into dynamic Control oil by pipeline
Road, the brake control valve group 8 of self-actuating brake control unit, ball valve 10, water brake brake 11, turn guide's brake control valve 9
Disk motor 12 constitutes brake control oil circuit, and for hydraulic pump 1 to turntable motor 12 for pressure oil, 1 pressure oil of hydraulic pump passes through main overflow
Valve 2, pilot control valve 3 are adjusted, and main 2 working hole P of overflow valve is connected with 6 oil inlet P of proportional reversing valve, and proportional reversing valve 6 works
Mouth A, B are connected with 8 pressure oil port A, B of brake control valve group and turntable motor 12 working hole A, B, and 7 working hole of balanced valve is connected on
On the rotating forward oil circuit of turntable motor 12,7 control mouth of balanced valve is connected with the oil return line that turntable motor 12 rotates forward；Brake control valve group
8 pilot port X are connected with 9 working hole A of guide's brake control valve, and 8 working hole BR of brake control valve group is connected with 10P1 mouthfuls of ball valve, ball
10P2 mouthfuls of valve are connected with 11 pressure port P of water brake brake；Guide's brake control valve 9,5 oil inlet P of ratio change-over pilot valve
It is connected with 4 working hole P2 of pressure reducing valve.
Guide's brake control valve 9 has control function of going beyond one's commission, the un-brake before operation；After guide's 9 un-brake of brake control valve,
The commutation of 8 inside hydraulic control reversing valve core of brake control valve group；When operation 5 handle of ratio change-over pilot valve to 12 positive and negative rotation of turntable motor
When working position, system pressure oil reaches the differential spool inside brake control valve group 8 by proportional reversing valve 6, balanced valve 7, poor
Movable valve plug is opened under differential pressure action, and system pressure oil continues flow through 8 inner pressure relief spool of brake control valve group and hydraulic control is changed
To after spool, automatic un-brake is carried out to water brake brake 11；When operation 5 handle of ratio change-over pilot valve is located at middle position,
For the differential spool in the inside of brake control valve group 8 due to not opening without pressure difference at both ends, pressure oil can not reach water brake brake 11
Pressure port P, turntable motor 12 brake；When operating the rotating forward of 5 handle drives turntable motor 12 of ratio change-over pilot valve, pressure oil
It is rotated forward through 7 internal one-way valve core rear-guard turn disk motor 12 of balanced valve, when turntable motor 12 is reversely rushed during main story
Hitting causes the generation of turntable motor 12 when being inverted trend, and 7 control mouth 3 of balanced valve leads to balanced valve 7 due to no pressure signal input
Internal sequence spool is closed, and hydraulic oil can not flow back, and prevents turntable motor 12 when rotating forward due to suddenly by external impacts
It influences and leads to the generation for being inverted problem.When hydraulic system fault or when encountering emergency case, guide's brake control valve 9 is closed
, 8 pilot port X no pressure oil of brake control valve group input, internal hydraulic control reversing valve core does not commutate, and pressure oil will be unable to reach liquid
Brake actuator 11 is pressed, realizes that the control of going beyond one's commission under emergency work condition carries out emergency brake to hydraulic swivel head motor 12.
