Abstract
The invention provides a loading station main ore pass ore reserve real-time monitoring device which comprises a main controller, an ore drawing machine and a radar level meter, wherein the signal output end of the radar level meter is connected with the signal input end of the main controller; the control signal output end of the main controller is connected with the signal input end of the ore drawing machine; the radar level meter is used for monitoring ore reserves in a main ore pass in real time and feeding the monitoring data back to the main controller in real time; an ore reserve upper limit value and an ore reserve lower limit value are arranged inside the main controller; the main controller receives the ore reserve data fed back by the radar level meter, judges whether the data exceed the presupposed limit values in real time and sends a corresponding order to control the operation of the ore drawing machine according to the judging result, and the ore drawing machine is used for drawing ore according to the order of the main controller. The main controller guarantees that the ore reserve in the main ore pass cannot be excessive and influence the ventilation according to the ore reserve fed back by the radar level meter in real time, and the ore drawing machine and the throat cannot damage due to the emptiness of the ore reserve in the main ore pass.
Description
Technical field
The present invention relates to mining equipment field, particularly relate to ore amount real-time monitoring device in a kind of loading depot main chute.
Background technology
In current loading depot main chute, ore quantity cannot check for a long time, cause loading depot operating personnel cannot grasp ore quantity in main chute, vibration can be accelerated after main chute emptying, accelerate the wearing and tearing of ore drawing machine and reducing, affect underground ventilating, to operator safety hidden danger in loading depot.
Summary of the invention
The object of this invention is to provide ore amount real-time monitoring device in a kind of loading depot main chute, for realizing the Real-Time Monitoring to ore amount in main chute, avoid because of after main chute emptying to the damage of mining equipment, and ensure the potential safety hazard of loading depot operating personnel.
Ore amount real-time monitoring device in a kind of loading depot main chute, comprise master controller, ore drawing machine, radar levelmeter, the signal output part of described radar levelmeter connects the signal input part of master controller, and the control signal output terminal of master controller connects the signal input part of ore drawing machine; Described radar levelmeter is used for the ore amount in Real-Time Monitoring main chute, and by Monitoring Data Real-time Feedback to master controller; Master controller inside arranges an ore amount higher limit and an ore deposit amount lower limit, and after the ore amount data of the radar levelmeter received feedback, whether real-time judge has exceeded pre-set limit, and sends the motor-driven work of corresponding order Controlled ore drawing according to judged result; Ore drawing machine is used for carrying out ore drawing according to the instruction of master controller.
When the ore amount that described master controller judges in main chute has exceeded ore amount higher limit, master controller has sent instruction Controlled ore drawing machine ore drawing; When master controller judges that ore amount in main chute is lower than ore amount lower limit, master controller sends to ore drawing machine and stops ore drawing instruction.
What described radar levelmeter adopted is 26G radar levelmeter.
Beneficial effect of the present invention is, master controller is according to ore amount in the well of radar levelmeter Real-time Feedback, the action of real-time Controlled ore drawing machine ore drawing, ensure the unlikely too much impact ventilation of ore amount in main chute, also ensure that in main chute, the unlikely emptying of ore amount causes the damage of ore drawing machine and reducing simultaneously.
Below in conjunction with accompanying drawing, ore amount real-time monitoring device in loading depot of the present invention main chute is described further.
Accompanying drawing explanation
Fig. 1 is ore amount real-time monitoring device schematic diagram in loading depot main chute.
Embodiment
As shown in Figure 1, in loading depot of the present invention main chute, ore amount real-time monitoring device comprises master controller, ore drawing machine, radar levelmeter, the signal output part of radar levelmeter connects the signal input part of master controller, and the control signal output terminal of master controller connects the signal input part of ore drawing machine; Radar levelmeter is used for the ore amount in Real-Time Monitoring main chute, and by Monitoring Data Real-time Feedback to master controller; Master controller inside arranges an ore amount higher limit and an ore deposit amount lower limit, and after the ore amount data of the radar levelmeter received feedback, whether real-time judge has exceeded pre-set limit, and sends the motor-driven work of corresponding order Controlled ore drawing according to judged result; Ore drawing machine is used for carrying out ore drawing according to the instruction of master controller.
When the ore amount that master controller judges in main chute has exceeded ore amount higher limit, master controller has sent instruction Controlled ore drawing machine ore drawing; When master controller judges that ore amount in main chute is lower than ore amount lower limit, master controller sends to ore drawing machine and stops ore drawing instruction.What described radar levelmeter adopted is 26G radar levelmeter, and wavelength is shorter, and have better reflection at the solid surface tilted, this has well adapted to the surface of ore storage complexity; Therefore high s/n ratio, even if also can obtain more excellent performance when fluctuating, even if still can keep measuring accurately under sending out assorted operating mode under main chute like this.
In practical application, in loading depot main chute, ore amount real-time monitoring device main Neng Shi loading depot operating personnel grasp ore deposit amount in main chute in real time.
The microwave pulse that the antenna transmission of the concrete radar levelmeter installed above main chute is narrower, transmit downwards through antenna, microwave is reflected back after touching measured medium surface, again automatically converted to thing position signal after antenna system reception, and be transferred to master controller, according to the data received, master controller judges whether the ore amount in now main chute has exceeded default ore amount higher limit or lower limit, if ore amount has exceeded the ore amount higher limit preset in judgement main chute, then master controller sends steering order, Controlled ore drawing machine ore drawing, too much unlikely to ensure the ore amount in main chute, if master controller judged result is that in main chute, ore amount has been less than ore amount lower limit, then Controlled ore drawing machine stops ore drawing, to ensure the unlikely emptying of ore in main chute.
The present invention can make loading depot personnel grasp ore deposit amount in main chute in real time, thus avoids drop shaft emptying to bring to obtain harmful effect, eliminates unsafe factor, reduces the maintenance amount of loading depot ore drawing machine and reducing; It also avoid the ore amount overheap in drop shaft and the not smooth impact of the underground ventilating caused simultaneously.
Above-described embodiment is only be described the preferred embodiment of the present invention; not scope of the present invention is limited; under not departing from the present invention and designing the prerequisite of spirit; the various distortion that those of ordinary skill in the art make technical scheme of the present invention and improvement, all should fall in protection domain that claims of the present invention determines.
