Abstract
The utility model relates to an electric lock protection device for mining electric locomotive door. A door magnistor is arranged on the edge of the mining electric locomotive door. The normally open contact of the door magnistor simultaneously controls power-on and power-off of a relay J and a DC contactor coil. The normally open contact J-3 and the normally closed contact J-4 of the relay J control voice circuits respectively, the normally open contact of the DC contactor controls the mains supply of the mining electric locomotive. Infrared detectors are arranged at the front-end and the back-end of the top of the mining electric locomotive. The normally open signal output lines of the infrared detectors simultaneously control warning circuits, mining electric locomotive door open indicating circuits and mining electric locomotive door close indicating circuits, and this can effectively control the behaviors of drivers, and guarantee the road safety of drivers.
Description
(1), technical field
The utility model relates to a kind of mining electric locomotive door electric locking protective device.
(2), background technology
The mining electric locomotive transportation occupies extremely important position, and it is the throat that connects main main haulage roadway and digging inside.Locomotive most in the process of moving drivers ignore rules and regulations, and closed door does not lean out geomantic omen pipeline, the anchor hung in car outer and car or the tunnel with health and lane wall projection such as fastens and bump, and the casualty accident that causes is of common occurrence.Therefore " safety regulations in coal mine " the 348th " in the locomotive operation, forbidding head or body part are leant out outside the car ".But owing to there is not protective device, in fact, driver's behavior is uncontrollable.
(3), summary of the invention
In order to overcome the shortcoming of prior art, the utility model provides a kind of mining electric locomotive door electric locking protective device, and it can control driver's behavior effectively, guarantees driver's traffic safety.
The technical scheme in the invention for solving the technical problem is: door status switch is installed in the edge of mining electric locomotive car door, the break-make of its normally open contact while control relay J and D.C. contactor coil, the constant open contact J-3 of relay J and constant close contact J-4 control second, third voice leg of sound circuit respectively, the normally open contact control mining electric locomotive general supply of D.C. contactor; Infrared Detectors is installed in the front and back end at mining electric locomotive top, its output line of often opening is controlled warning circuit simultaneously, mining electric locomotive indicating circuit and the mining electric locomotive indicating circuit of closing the door that opens the door, the warning indicating circuit has the relay C coil of alarm lamp RD and its polyphone, the constant open contact of relay C is controlled article one voice leg of described sound circuit, the mining electric locomotive indicating circuit that opens the door has the constant close contact J-1 of the relay J of open the door indicator lamp KD and its polyphone, the mining electric locomotive indicating circuit of closing the door has the constant open contact J-2 of the relay J of close the door indicator lamp GD and its polyphone, described first, article second and the 3rd, voice leg is sent corresponding voice suggestion.
Owing to adopt the utility model to control the car door of mining electric locomotive,, guarantee driver's traffic safety so can control driver's behavior effectively.Because there is Infrared Detectors the front and back of mining electric locomotive, in the driving process of tunnel, if when pedestrian or constructor were arranged, the utility model noted having personnel to occur in the tunnel, the place ahead with the voice suggestion driver, the driver is slowed down in advance avoid the generation of accident.
(4), description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the utility model circuit theory diagrams.
(5), the specific embodiment
As shown in drawings, door status switch 22 is installed in the edge of mining electric locomotive car door, and its normally open contact is by 7,8,9, the 10 praps while control relay J of connecting terminal block and the coil break-make of D.C. contactor 21.The constant open contact J-3 of relay J and constant close contact J-4 control second, third voice leg of sound circuit 23 respectively by 5,4 praps of connecting terminal block.The normally open contact control mining electric locomotive general supply of D.C. contactor 21.Infrared Detectors 24 is installed in the front and back end at mining electric locomotive top, and its output line of often opening is controlled warning circuit, mining electric locomotive indicating circuit and the mining electric locomotive indicating circuit of closing the door that opens the door simultaneously.The warning indicating circuit has the relay C coil of alarm lamp RD and its polyphone, and the constant open contact of relay C is controlled article one voice leg of described sound circuit 23 by 6 praps of connecting terminal block.The mining electric locomotive indicating circuit that opens the door has the constant close contact J-1 of the relay J of open the door indicator lamp KD and its polyphone.The mining electric locomotive indicating circuit of closing the door has the constant open contact J-2 of the relay J of close the door indicator lamp GD and its polyphone.
Described article one voice leg is sent the voice suggestion of " there is the pedestrian in the place ahead, and drive slow please ".Described second voice leg is sent the voice suggestion of " please drive by chapter, wish you safety ".Described the 3rd voice leg sent the voice suggestion of " for you and other people safety, please with closing of the door ".
Behind the locomotive closing of the door, the normally open contact closure of door status switch 22 is connected the coil power of D.C. contactor 21 and relay J.D.C. contactor 21 is connected the mining electric locomotive general supply.The constant open contact J-3 closure of relay J drives the voice signal that voice driven circuit 23 sends " please drive by chapter, wish you safety ", the constant open contact J-2 closure of relay J simultaneously, and the indicator lamp GD that closes the door is bright.If the locomotive car door is not closed or opened, then the normally open contact of door status switch 22 disconnects, and the mining electric locomotive general supply is cut off and can not starts or stop.Simultaneously the constant close contact J-1 of relay J and the J-4 closure that resets makes voice driven circuit 23 send " for you and other people safety, please with the locomotive closing of the door ", reminds driver's closed door or cuts off general supply.The place ahead has the pedestrian to occur if locomotive is advanced under steam, the normally open contact closure of Infrared Detectors 24, the warning indicating circuit is connected, alarm lamp RD is bright, the constant open contact closure of relay C, sound circuit 23 sends the voice suggestion of " there is the pedestrian in the place ahead, and drive slow please ", the driver is slowed down in advance watch for pedestrians.
