The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further described.
As shown in Figure 1, the safe traveling anticollision device of a kind of coke oven coal car provided by the invention, comprise two 24V correlation type photoelectric switchs, be made as a photoelectric switch and No. two photoelectric switchs, wherein a photoelectric switch transmitting terminal 2 is arranged on coal car walking rails fender pile support top, and be directly connected with 24V direct supply 1, No. one photoelectric switch receiving end 3 is arranged on walking wheel pillar inner side, coal car rear.No. two photoelectric switch receiving end 4 is arranged on walking wheel pillar inner side, coal car the place ahead, and No. two photoelectric switch transmitting terminal 5 is arranged on the walking wheel pillar inner side that adjacent standby coal car is relative, and is directly connected with 24V direct supply 1.The setting of two photoelectric switch receiving ends makes coal car can aim at and optical signal is converted to electric signal during through two photoelectric switch transmitting terminals in photoelectric switch controllable distance.
As shown in Figure 2, each photoelectric switch receiving end is all connected with intermediate relay by electric wire, two normally closed contacts of intermediate relay are separately positioned on the driving second gear of coal car traveling gear third speed control circuit, on driving third gear speed governing circuit, open contact is arranged on one grade of deceleration branch road of coal car traveling gear driving, intermediate relay receives after the electric signal of photoelectric switch transmission, two normally closed contacts disconnect, only have one grade of deceleration branch road open contact of driving closed, thereby coal car traveling gear can only be travelled under the state of dead slow, intermediate relay open contact is closed simultaneously, make the buzzer warning being connected with intermediate relay open contact, further remind operation driver will control road speed.
As shown in Figure 3, as one embodiment of the present of invention, by third gear speed control switch, regulate motor winding to realize third gear speed governing, photoelectric switch is connected with intermediate relay, intermediate relay and buzzer phone, 24V power supply are connected into a complete loops mutually, intermediate relay open contact is arranged on one grade of deceleration branch road of driving, and two normally closed contacts of intermediate relay are separately positioned on the branch road on the branch road between coal car third gear speed control switch driving second gear contact and magnet coil auxiliary winding and between coal car third gear speed control switch driving third gear contact and magnet coil.When photoelectric switch receiving end receives after optical signal, opto-electronic conversion, electric signal is sent to intermediate relay, intermediate relay normally closed contact disconnects, and open contact is closed, and the loop that intermediate relay is connected mutually with buzzer phone, electromagnetic switch K2,24V power supply is connected, buzzer warning, the one grade of circuit of driving a vehicle is connected, and driving second gear, third gear disconnect, thereby coal car traveling gear can only be travelled under the state of dead slow.
As another embodiment of the present invention, as shown in Figure 2, adopt frequency converter to realize speed governing, and frequency converter is arranged to driving third gear respective frequencies, Frequency Converter Control motor speed, frequency converter is connected with telltale.Coal car traveling is to decelerate position, it is photoelectric switch transmitting terminal, during active distance between receiving end, photoelectric switch receiving end opto-electronic conversion, electric signal is sent to intermediate relay, intermediate relay response, open contact is closed, normally closed contact disconnects, driving second gear, two normally closed contacts of driving third gear speed governing circuit disconnect, only have one grade of deceleration branch road open contact of driving closed, electric signal sends to one grade of port of frequency converter, thereby make frequency converter act on one grade of frequency, running mechanism motor speed is reduced to a low speed numerical value immediately, the traveling speed of coal car can slow down, the indoor buzzing warning device of driver operation can be sounded simultaneously, on the telltale of coal car, show speed limit speed and the traveling electric current that adds coal car, facilitate the further estimate of situation of driver.In addition, buzzer phone and traveling speed Current Display are specifically arranged in coal car operator's compartment
Therefore the present invention effectively prevents from, because two coal cars are at the same time in operation process, because excessive velocities causes car to car impact, causing coal car to derail; Prevent from causing bumping against fender pile because coal car traveling speed is too fast simultaneously, cause coal car derailing, safety misadventure occurs.This device can be protected coal car vehicle device and driver's safety, and convenient operation is convenient to control, and is convenient to the features such as maintenance.
In addition, consider concrete practical situations, coke oven coal car self high temperature tends to electric elements to cause damage, the all elements of the present invention are provided with thermal insulation layer, between element, connecting electric wire is placed in galvanized pipe, and in galvanized pipe junction and the junction of galvanized pipe and electric elements be provided with fire prevention cable cover, with thoroughly heat insulation.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
