The specific embodiment
A kind of buffer stop that shortens tram guard protection dead area, comprise arrester 6, monitoring speed measuring device 1 and autonomous cruise speed system 7, the two ends, the left and right sides of arrester 6 are connected with the energy disperser 4 that is fixed on the roadway both sides by snub rope 5, arrester 6 joins by hauling rope 2 and hauling rope draw off gear, and described hauling rope draw off gear is provided with and puts rope mechanism fast.
Can hang on the cover rod at roadway top between above-mentioned arrester 6 and energy disperser 4 by lifting rope, the two ends of cover rod join by snub rope and energy disperser, are connected with hauling rope between the two ends of cover rod and the arrester.Sport car is adopted the acquisition mode block the cover combination, prevent that bunching from scurrying car, improve the reliability that buffer stop uses.
Described monitoring speed measuring device 1 adopts radar velocity measurement sensor or two infrared pickoff or the two combination.Also can adopt the sensing mode of other effective detection speed.
A kind of embodiment is: described hauling rope draw off gear can be a releasing winch 9, puts rope mechanism fast and is located at the reel of releasing winch 9 and the hulling and separating machine structure between its transmission device, and the hulling and separating machine structure links to each other with autonomous cruise speed system 7 by executive circuit.Releasing winch 9 can be traditional winch by solenoid control etc.Adopt two infrared pickoffs to carry out the speed of a motor vehicle, parking stall measure, traction machine adopts releasing winch, and the hulling and separating machine structure adopts magnetic clutch, and the winch output shaft is connected with reel by magnetic clutch.Block this two sensors successively as mine car, can detect the mine car service direction, by the spacing of two sensors and time difference of blocking mine car moving velocity as can be known.It is descending to detect mine car, and output is opened the net signal and given releasing winch, and arrester is opened; It is up to detect mine car, and arrester falls to closing.As detect the descending hypervelocity of mine car, and magnetic clutch separates winch with reel, and reel is counter-rotating rapidly under the action of gravity of arrester, and arrester hurtles down and closes.
Another kind of embodiment is: described hauling rope draw off gear is traction cylinder 3, and what put fast that rope mechanism is provided with control traction cylinder 3 takes off the branch relay.
Pneumatic mode is adopted in the arrester folding and unfolding, by hauling rope 2, traction cylinder 3, arrester 6, steel wire snub rope 5, energy disperser 4, radar velocity measurement sensor 1, electromagnetism-gas-driving valve CF1, take off branch relay J 2 and form.Can detect the characteristic of moving target by radar velocity measurement sensor 1, realize the function of parking stall sensor.Test the speed by radar velocity measurement sensor 1, surpass the given speed thresholding and be judged to be the sport car state, realize the function of sport car state sensor.Hauling rope 2 is realized the function of connecting device.Take off the function that sub-controller is taken off in 2 realizations of branch relay J.Traction cylinder 3 is realized the function of draw gear.
Principle of work: certain zone before and after the radar velocity measurement sensor 1 electric wave irradiation arrester, enter this zone as mine car, radar velocity measurement sensor 1 detects mine car and moves, and opens the net signal to electric cabinet control traction cylinder 3 by control end G output, and arrester 6 is opened.Mine car moves not output signal by no mine car in radar velocity measurement sensor 1 search coverage of back, 3 playback of electric cabinet control traction cylinder, and arrester 6 falls to closing.Detect the mine car hypervelocity as radar tachogenerator 1, R outputs control signals to electric cabinet by control end, makes trip relay J2 will draw cylinder 3 quick playback, and arrester 6 falls to closing, and electric cabinet output signal FB control simultaneously gig stops and alarm.The position that spacing rope control arrester falls, steel rope 5 and energy disperser 4 make arrester 6 carry out the flexible buffer energy-absorbing.
Electrical principle is as scheming:
J1 is for rising network control system relay, one end and resistance R are 1 continuous, the other end of R1 and power supply BD+hold to be connected, the J1 other end is connected in the end of the contact J2-2 of relay J 2, the train signal mouth G of the other end of J2-2 and radar velocity measurement sensor 1 is connected.
J2 is for taking off the branch relay, one end and resistance R 2 links to each other, the other end of R2 and power supply BD+hold to be connected, the end of the contact J2-1 of the end of the J2 other end and light-emitting diode D1 negative terminal, buzzer phone Y, the overspeed signal mouth R of radar velocity measurement sensor 1, relay J 2 is connected, the other end of the contact J2-1 of J2 and power supply BD-end is connected, light-emitting diode D1 anode is connected with resistance R 3 one ends, the other end of the R3 other end, Y and power supply BD+hold to be connected.The contact J2-3 of relay J 2 stops as winch and controls, and the safety return circuit control lifting winch that seals in lifting winch stops.
K1 is an arrester lower limit travel switch, one end and power supply BD-end is connected, the other end is connected with light-emitting diode D2 negative terminal, the D2 anode is connected with an end of resistance R 4, the other end of R4 and power supply BD+hold to be connected.
K2 is an arrester upper limit travel switch, one end and power supply BD-end is connected, the other end is connected with light-emitting diode D3 negative terminal, the D3 anode is connected with an end of resistance R 5, the other end of R5 and power supply BD+hold to be connected.
Q1 is the electromagnet of electromagnetism-gas-driving valve CF of traction cylinder 3, one end and power supply BD-end is connected, the other end is connected with the open contact J1-1 of the network control system of liter relay J 1], the other end of J1-1 and power supply BD+hold to be connected.
Electric control theory: radar velocity measurement sensor 1 electric wave irradiation arrester 6 front and back are the zone necessarily.When there not being mine car to enter this zone, the G end output state of radar velocity measurement sensor 1 is a high resistance, not adhesive of J1, and electromagnetism-gas-driving valve CF does not have electricity, draws cylinder 3 at the state that resets certainly, the cylinder playback, arrester 6 is caught.Arrester 6 is caught and is put in place, lower limit travel switch K1 closure, and indication is caught and is put in place.Enter this zone as mine car, the G end output state of radar velocity measurement sensor 1 is a low resistance, and J1 gets electric adhesive through R1, J1 open contact closure, and the Q1 adhesive, electromagnetism-gas-driving valve CF makes traction cylinder 3 incomes, 6 liters of nets of arrester.6 liters of nets of arrester put in place, upper limit travel switch K2 closure, and indication rises net and puts in place.Radar velocity measurement sensor 1 detects mine car hypervelocity sport car, and its R end output state is a low resistance, the J2 adhesive, and the contact J2-1 closure of J2, the J2 self-insurance, J2-2 disconnects J1 is resetted, and draws cylinder 3 at the state that resets certainly, the cylinder playback, arrester 6 is caught.The J2-3 closure is controlled gig parking and alarm simultaneously.
