Pipe is connect with the oil inlet, and the oil cylinder input terminal is connect by oil pipe with the oil outlet.
As a preference of the present invention, the oil inlet and the oil outlet of the hydraulic valve are straight-through, and including two-way point
Branch, respectively proportional throttle valve and overflow valve.
When the hydraulic revolution speed is not high, oil liquid can not overcome institute from the proportional throttle valve oil return, the cylinder thrust
The restoring force for stating reset spring clamps the clamping section；After the hydraulic pump reaches certain revolving speed, the proportional throttle valve back
Pressure increases, and the cylinder thrust overcomes the restoring force of the reset spring to clamp the clamping section；The hydraulic pump reaches more
After high certain revolving speed, back pressure reaches the overflow valve set pressure, and oil liquid is from the overflow valve oil return.
As a preference of the present invention, when the traction sheave revolving speed reaches 1.1 ~ 1.2 times of normal maximum speed, it is described hydraulic
Pump output power makes the oil cylinder reach bottom, and the manipulation portion drives the clamping section to clamp the traction sheave.
As a preference of the present invention, when the traction sheave revolving speed reaches 1.4 ~ 1.6 times of normal maximum speed, the clamping
The torque and carriage that portion clamps the traction sheave reach balance to the torque of the traction sheave, and the traction wheel speed keeps steady
It is fixed.
As a preference of the present invention, triboelectricity device is also equipped on the traction sheave central axis, the traction wheel speed
Higher, it is bigger that the triboelectricity device generates electric current.
As a preference of the present invention, the triboelectricity device is connect by electric wire with the proportional throttle valve, the ratio
Throttle valve throttling through-current capacity generates size of current with the triboelectricity device and is negatively correlated.
The traction wheel speed is higher as a result, and the proportional throttle valve throttling action is stronger, and the oil cylinder is under pressure more
Greatly, the brake clamp is bigger to the clamping force of the traction sheave.
In conclusion the invention has the following advantages:
Hydraulic self-adapting elevator traction sheave brake system of the invention is rotated using hydraulic pump with traction sheave, by hydraulic
Valve, the hydraulic cylinder control tight traction sheave of brake clip clamp play braking effect, and pass through the electric current of the revolving speed of pump and electric organ
Brake clip clamp clamp force size is controlled, realizes self adaptive control, so that carriage is slowed down and drops, and maintain under a stable speed
Pendant on earth, reduces the shocking damage that carriage is subject to, while excluding to slip the risk of ladder.
Detailed description of the invention
Fig. 1 is structural schematic diagram when hydraulic self-adapting elevator traction sheave brake system of the present invention clamps brake；
Fig. 2 is structural schematic diagram when hydraulic self-adapting elevator traction sheave brake system of the present invention does not clamp.
Specific embodiment
Below in conjunction with attached drawing, by specific embodiment, the invention will be further described.
As shown in Figure 1, Figure 2, a kind of hydraulic self-adapting elevator traction sheave brake system, including traction sheave 1,1 central axis of traction sheave
One end be connected with hydraulic pump 2, hydraulic pump 2 is rotated with the rotation of traction sheave 1, and revolving speed is directly proportional；
The circumference side of traction sheave 1 is provided with brake clamp 3, and brake clamp 3 includes being located at 1 two sides of traction sheave to traction
The clamping section 31 that wheel 1 is clamped or unclamps, and adjust the manipulation portion 32 of 31 state of clamping section；
Clamping section 31 is equipped with reset spring 311, and reset spring 311 has the power for making clamping section 31 unclamp traction sheave 1；
Manipulation portion 32 is equipped with oil cylinder 321, and 321 extending action of oil cylinder, which has, drags adjusting clamping section 31 clamping of manipulation portion 32
The movement of running wheel 1, hydraulic pump 2 carry out oil communication by hydraulic valve 4 and oil cylinder 321.
Hydraulic valve 4 includes oil inlet 4a and oil outlet 4b, and 2 output end of hydraulic pump is connect by oil pipe with oil inlet 4a, oil
321 input terminal of cylinder is connect by oil pipe with oil outlet 4b.
The oil inlet 4a and oil outlet 4b of hydraulic valve 4 are straight-through, and including two-way branch, respectively proportional throttle valve 41 and overflow
Flow valve 42.
When 2 revolving speed of hydraulic pump is not high, oil liquid can not overcome reset spring from 41 oil return of proportional throttle valve, 321 thrust of oil cylinder
311 restoring force clamps clamping section 31；After hydraulic pump 2 reaches certain revolving speed, 41 back pressure of proportional throttle valve increases, oil cylinder 321
Thrust overcomes the restoring force of reset spring 311 to clamp clamping section 31；After hydraulic pump 2 reaches higher certain revolving speed, back pressure reaches
To 42 set pressure of overflow valve, oil liquid is from 42 oil return of overflow valve.
