detailed description of the invention:
In order to understand the utility model better, explain embodiment of the present utility model in detail below in conjunction with accompanying drawing.
Detailed description of the invention: as shown in Figure 1, fluctuating lane, a kind of inclined gallery braking car, comprises the walking chassis 1 below car body and car body, and walking chassis 1 is rotatablely equipped with some wheels 2 by lower end, and wheel 2 rolls and is arranged on track 10.Walking lower end, chassis 1 is installed fifth wheel 5 rolling and is arranged on track 10; Fifth wheel 5 is coaxially connected by adapter shaft with two-way pump 11, as shown in Figure 3.The oil inlet of two-way pump 11 is connected to hydraulic reservoir.Walking chassis 1 on be also provided with Forcipated brake 3, during for braking with track 10 wipe contact, generation braking force; The oil cylinder of described Forcipated brake 3 is connected to hydraulic reservoir by hydraulic control one-way valve, and the oil outlet of two-way pump 11 is connected to the control mouth of hydraulic control one-way valve.
When this fluctuating lane, inclined gallery braking car normally runs, it is moved along track 10 by the One On The Chassis wheel 2 of walking, when there is disconnected rope or sport car phenomenon, fifth wheel 5 rotating speed increases, two-way pump 11 oil drain quantity is driven to increase, hydraulic oil enters hydraulic control one-way valve hydraulic control mouth, control reverse opening hydraulic control one-way valve, the oil cylinder draining of Forcipated brake 3, simultaneously Forcipated brake 3 promotes piston and carries out embracing rail braking to track under disc spring effect, avoid the mine car of transportation device, flat truck generation driving phenomenon, cause the generation of casualty accident.
As shown in Figure 2, a wheel 2 is rotatablely equipped with gear 8 wherein, chassis 1 is provided with non-contact type opto-electronic pickup 9 with gear 8 corresponding section in walking, the oil cylinder of Forcipated brake 3 is connected to hydraulic reservoir through change-over valve, non-contact type opto-electronic pickup 9 and change-over valve are electrically connected on PLC, when non-contact type opto-electronic pickup 9 points to tooth top or the tooth root position of gear 8 respectively, it produces high level or low level signal respectively.The running velocity of this fluctuating lane, inclined gallery of low and high level calculated signals braking car that PLC is constantly sent by non-contact type opto-electronic pickup 9, when the setting value of speed higher than PLC, PLC controls change-over valve action, make hydraulic oil off-load in the back cavity of the oil cylinder of Forcipated brake 3 to fuel tank, thus Forcipated brake 3 is braked.To be tested the speed by opto-electronic pickup and hydraulic pressure tests the speed conbined usage, there is range rate accuracy high, more safe and reliable feature.
This programme is comprised being rotated by rotating shaft 7 and is installed on walking the One On The Chassis wheel carrier 4 and extension spring 6, and fifth wheel 5 rotates and is installed on wheel carrier 4, and one end of extension spring 6 is fixed on walking chassis 1, and its other end is fixed on wheel carrier 4.Under the pulling of extension spring 6 elastic force, the close contact of fifth wheel 5 and track 10 can be guaranteed, and make fifth wheel 5 and track 10 have larger positive pressure, it is hereby ensured that this fluctuating lane, inclined gallery braking car fifth wheel 5 in traveling process can roll along track 10 all the time accurately, there is provided and test the speed, further increase range rate accuracy.
Can also be provided with the pressure sensor for checking system pressure in hydraulic efficiency pressure system, the oil cylinder of Forcipated brake 3 is connected to hydraulic efficiency pressure system electric oil pump, and pressure sensor and electric oil pump are electrically connected on PLC.When the pressure of hydraulic efficiency pressure system is lower than rated value, in order to avoid the oil cylinder of Forcipated brake 3 causes off-load under environment under low pressure, make drg misoperation, now pressure signal is fed back to PLC by pressure sensor, and the electric oil pump of PLC hydraulic control system starts, and suppresses, to reach after system pressure in automatic stopping, ensure that this fluctuating lane, inclined gallery braking car caliper brake 3 in normal course of operation is in opening all the time, avoid manual detection, add safety.And adopt electric oil pump to carry out fluid infusion, it also avoid and manually suppress operation, reduce labour intensity.
Further, non-contact type opto-electronic pickup 9 is connected to endless rope winch control setup main frame by PLC signal.When non-contact type opto-electronic pickup 9 detects that wheel 2 speed rotating speed exceedes setting value, Forcipated brake 3 is braked, signal is issued PLC by non-contact type opto-electronic pickup 9 simultaneously, and PLC controls endless rope winch control setup main frame sudden stop, avoids fault spread.
Above-mentioned explanation is not to restriction of the present utility model; the utility model is also not limited in above-mentioned citing; the change that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model.
