[description of drawings]
In conjunction with the embodiments the utility model is further described with reference to the accompanying drawings.
Fig. 1 is a structural principle block diagram of the present utility model.
[specific embodiment]
See also shown in Figure 1ly, embodiment of the present utility model is described in detail.
As Fig. 1, rail 3, PLC controller 41, hand behaviour device 42, AC contactor 43 that it comprises driving 1, coal bunker 2, is used to drive a vehicle and moves.Described hand behaviour's device 42 and AC contactor 43 all are connected in described PLC controller 41, and described PLC controller 41 also is connected with running LED 44.Described PLC controller 41, hand behaviour device 42, AC contactor 43, running LED 44 all are arranged on the control box 4.Described AC contactor 43 is connected to the motor that is arranged in the described driving 1 by cable one, and described motor comprises: the lifting motor 12 that is used to control the translation motor 11 of described driving 1 translation and is used to control described coal bunker 2 up-and-down movements.Described driving 1 installing and locating bar 1, and described rail 3 is provided with the position switch 31 that cooperates with radius stay 1, decide as circumstances require in the quantity and the position of described position switch 31.Described position switch 31 is connected with described PLC controller 41 by cable two, described coal bunker 2 installing and locating bars 2 21, and described driving 1 be provided with match with radius stay 2 21 on position switch 14, the described position switch 14 of going up is connected with described PLC controller 41 by cable three, be provided with a steel rope 5 along described rail 3 directions, described cable one, cable three are connected to the corresponding motor in the described driving 1, last position switch 14 by the pulley on the described steel rope 5.Described PLC controller 41 inside are provided with timer.
Described hand behaviour device 42 is used for artificial M/C, and PLC controller 41 is adjusted the operation of driving 1 and coal bunker 2 according to the signal of the instruction of hand behaviour device 42 and position switch.Described running LED 44 is used to show the running state of driving 1 and coal bunker 2.On the rail 3 of driving 1 operation, adorn a position switch 31 along horizontal direction in the position that each requires to stop, when described driving 1 runs to target parking position and puts, last 1 the radius stay 1 of driving a vehicle is stirred the position switch 31 of this position, thereby send positioning signal to PLC controller 41, described PLC controller 41 is controlled the sway of driving 1 again by AC contactor 43, translation motor 11; When described coal bunker 2 upward movements, radius stay 2 21 on the coal bunker 2 is stirred the last position switch 14 in the described driving 1, thereby send positioning signal to PLC controller 41, by the upward movement of AC contactor 43, lifting motor 12 control coal bunkers 2, described coal bunker 2 just moves downward and is regularly finished by described PLC controller 41 inner different timers described PLC controller 41 again.
Lifting an example now describes operating process of the present utility model:
Get the coal mouth when driving is parked in, coal bunker descends and to put in place, install coal after, by No. 3 boiler buttons (giving an example); Beginning is No. 3 boiler automatic stokings, and coal bunker rises to radius stay 2 21 when stirring position switch 14, stops, wait 2 seconds stable after; Driving, coal bunker begins to move forward, and during the coal mouth, radius stay 1 is stirred this position switch 31, stops under No. 3 boilers, wait 2 seconds stable after; Coal bunker descends, and PLC controller timer internal picks up counting and stopped after (adjustable) in 2 seconds; Coal bunker begins down coal, PLC controller timer internal pick up counting 35 seconds (adjustable); Time arrives, and coal unloads and finishes, and coal bunker rises to radius stay two when stirring position switch, stops, wait 2 seconds stable after; Driving, coal bunker move backward, turn back to when getting the coal mouth radius stay one and stir this position switch, stop, wait 2 seconds stable after, coal bunker begins to descend, the PLC timer internal picks up counting 46 seconds (adjustable), stops, and begins to coaling, and prepares to carry out coal task next time.
If driving exceeded schedule time promptly 46 seconds positive and negative 3 seconds in the process of getting the rising of coal mouth then is judged as fault at every turn, if the process that described coal bunker coal mouth under boiler rises exceeded schedule time 2 seconds positive and negative 1 second then was judged as fault, guaranteeing that breakdown of equipment or position switch take place in uphill process in driving can automatic train stop when malfunctioning and report to the police.
Described PLC inside has three timers to be used to be provided with three different timings: 1, coal bunker get the coal mouth from 46 seconds time descending of location point; 2, coal bunker Xia Meikou from 2 seconds time descending of location point; 3, coal bunker is in 35 seconds time that the Xia Meikou wait time is promptly unloaded coal.More than three time can grasp the incompatible change of button set on the device by hand.
Can manually control the operation of driving by hand behaviour device 42, perhaps when finding fault, parking that can be artificial.
The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented according to this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model contains.
