Alternatively, emergency brake system 100 can also comprise safety valve 10, and safety valve 10 can be connected between the oil outlet of Hydraulic Pump 1 and oil sources 9.
Be understandable that, when the output oil pressure of Hydraulic Pump 1 is excessive, safety valve 10 opens the oil outlet and the oil sources 9 that are communicated with Hydraulic Pump 1, can protect emergency brake system 100, particularly can prevent Hydraulic Pump 1 overvoltage.
In preferred embodiments more of the present invention, as shown in Figure 1, control cock 6 can be change-over valve, and control cock 6 can also comprise the 3rd valve port the 63, three valve port 63 is connected with oil sources 9, and the first valve port 61 is communicated with in the 3rd valve port 63 with the second valve port 62.
In other words, when needs perform braking during standstill action, the first valve port 61 is communicated with the second valve port 62, and the first valve port 61 and the 3rd valve port 63 disconnect, and accumulator 3 can be pressurizeed towards the oil cylinder of drg 7, drives drg 7 to brake; When not needing to perform braking during standstill action, the first valve port 61 is communicated with the 3rd valve port 63, and the first valve port 61 and the second valve port 62 disconnect, and the in-oil cylinder hydraulic oil of drg 7 can pass back into oil sources 9, with release the brake 7 by the 3rd valve port 63.
Alternatively, between the 3rd valve port 63 and oil sources 9, oil filter (not shown) can be provided with, in case the contaminating impurity oil sources 9 in non-return oil.
Particularly, as shown in Figure 1, control cock 6 can be solenoid directional control valve.Thus, the quick commutation realizing control cock 6 is convenient to.During solenoid directional control valve energising, the first valve port 61 is communicated with the second valve port 62, and the first valve port 61 and the 3rd valve port 63 disconnect; During solenoid directional control valve power-off, the first valve port 61 is communicated with the 3rd valve port 63, and the first valve port 61 and the second valve port 62 disconnect.As shown in Figure 1, solenoid directional control valve can be connected with power supply by switch 8, is optionally energized or power-off to control solenoid directional control valve.
As shown in Figure 1, emergency brake system 100 can also be provided with pressure relay 4, pressure relay 4 can be connected with the second valve port 62 and to commutate to control change-over valve (control cock 6).Thus, the effect of protection can be played to emergency brake system 100, and the work of emergency brake system 100 is more stable.
Further, as shown in Figure 1, emergency brake system 100 can also be provided with annunciator 5, annunciator 5 can be connected with pressure relay 4.
When the pressure of emergency brake system 100 is lower, annunciator 5 can give the alarm according to the signal of pressure relay 4, and prompting operator overhaul emergency brake system 100, to improve the safety of emergency brake system 100.Alternatively, annunciator 5 can be buzzer phone.
The working process of the emergency brake system 100 according to the embodiment of the present invention is described below:
As shown in Figure 1, start electric hydraulic pump 1, when the force value of accumulator 3 is lower than threshold pression value (such as 4.48MPa), Hydraulic Pump 1 can be filled with high pressure oil by prefill valve 2 towards accumulator 3, when the force value of accumulator 3 reaches pressure upper limit value (such as 6.03MPa), prefill valve 2 stops filling high pressure oil towards accumulator 3.
When needs perform braking during standstill action, solenoid directional control valve (control cock 6) is energized, solenoid directional control valve commutates, first valve port 61 is communicated with the second valve port 62, and the first valve port 61 and the 3rd valve port 63 disconnect, accumulator 3 is pressurizeed by the oil cylinder of solenoid directional control valve to drg 7, drives drg 7 to perform braking during standstill action.
When not needing to perform braking during standstill action, solenoid directional control valve power-off, solenoid directional control valve commutates again, first valve port 61 is communicated with the 3rd valve port 63, and the first valve port 61 and the second valve port 62 disconnect, the in-oil cylinder hydraulic oil of drg 7 can pass back into oil sources 9, with release the brake 7 by the 3rd valve port 63.
After the action of multiple exercise braking during standstill, force value in accumulator 3 constantly declines, until when the force value of accumulator 3 is lower than threshold pression value, Hydraulic Pump 1 can be filled with high pressure oil towards accumulator 3 again by prefill valve 2, until the force value of accumulator 3 reaches pressure upper limit value, like this, the force value of accumulator 3 can remain between threshold pression value and pressure upper limit value.
In sum, according to the emergency brake system 100 of the embodiment of the present invention, the fast response time of drg 7, exports lock torque large, operate steadily reliable, safety performance is good, and the volume of emergency brake system 100 is little, occupy little space, start and running noises little, productive costs is low.
