Description

Technical Field

[0001] The present invention relates to the technical field of mine material conveying equipment, and in particular to an auxiliary conveying mechanism based on gold ore mining and selection. Background Art

[0002] In the field of gold ore mining and dressing, the ore after blasting mining needs to be transported by belt conveyors. However, the irregular particle size and weight distribution of the ore and the uneven loading of the material during transportation put forward high requirements on the stability and safety of the conveying equipment. At present, gold ore conveying equipment, such as the more commonly used belt conveyor, has the following shortcomings in actual application:

[0003] In order to ensure safety during the transportation process and avoid conveyor belt overload or deviation caused by uneven loading or material accumulation of gold ore after blasting, current monitoring technology mainly relies on switching elements and sensors (such as touch switches, ultrasonic level meters, etc.) to achieve overload and deviation fault monitoring. However, in long-term operation, problems such as aging of switching elements and sensors and circuit failures will affect the reliability of the monitoring system. The switching elements and sensors used to monitor overload or deviation in existing conveying equipment lack a periodic fault detection mechanism, and cannot promptly identify faulty switching elements and sensors, which in turn affects the normal operation of the conveying system. Summary of the Invention

When the incomplete gear is about to disengage from the teeth, the monitoring matching opening and the monitoring end of the ultrasonic level meter are staggered. The reciprocating slide block blocks the monitoring end of the ultrasonic level meter, and the matching pressure block squeezes the pressure plate to move to the right.

[0041] The present invention provides an auxiliary conveying mechanism based on gold ore mining and dressing, which has the following beneficial effects:

[0042] The present invention uses an ultrasonic level meter to monitor the height of ore on the conveyor belt in real time. When the material height exceeds a threshold, an overload warning is issued. By coordinating the position of the deviation warning switch with the pressure plate, when the conveyor belt deviates, its edge presses the pressure plate, causing the silicone contact block to press the deviation warning switch to issue a deviation warning. To ensure that the above-mentioned function can play a corresponding warning role during the conveying process, the present invention is provided with a periodic fault detection. The monitoring cycle is set by running the monitoring timing module, so that the fault detection process can be automatically triggered according to the preset cycle. During periodic fault detection, the motor drives the incomplete gear transmission to drive the reciprocating slide to move, thereby simulating overload and deviation conditions by changing its own position and squeezing the position of the pressure plate. The simulated overload condition is used to verify whether the linkage response of the ultrasonic level meter and the overload sound and light alarm is normal. The simulated deviation condition is used to verify the effectiveness of the deviation detection and alarm function. This mechanism can periodically check for potential faults of sensors, alarms and control circuits, avoid missed or false alarms due to component failure, and ensure the long-term stable operation of the monitoring system.

The opening 302 is staggered with the monitoring end of the ultrasonic level meter 106. The reciprocating slide 3 blocks the monitoring end of the ultrasonic level meter 106, and the pressing block 301 squeezes the pressing plate 2 to move rightward. The silicone contact block 203 is pressed and contacted with the button end of the deviation warning switch 1011. The deviation warning switch 1011 is in a pressed and activated state.

When the locking bolts 1010 are locked along the threaded locking through hole 1016, the stud ends of the locking bolts 1010 are tightly attached to the bottom surface of the inner end of the limiting slot 501. Therefore, the position of the mobile base 102 can be temporarily limited and fixed by the tight contact between the stud ends of the locking bolts 1010 and the bottom surface of the inner end of the limiting slot 501.

[0061] The longitudinal support block 1, the transverse support block 101, the movable base 102, the limit plug 103, the deviation sound and light alarm 104, the overload sound and light alarm 105, the ultrasonic level meter 106, the side mounting plate 107, the motor 108, the incomplete gear 109, the locking bolt 1010, the deviation warning switch 1011, the limit plug 1012, the reciprocating movement opening 1013, the guide rod 1014, the return spring a1015, the threaded locking through hole 1016, the operation monitoring timing module 1017, the microcontroller 1018, the pressure plate 2, the limit plug 201, the return spring b202, the silicone contact block 203, the reciprocating slide 3, the matching pressure block 301, the monitoring matching opening 302, the reciprocating slide 303, the guide plug 304 and the gear 305 together constitute a set of operation monitoring mechanisms. The operation monitoring mechanisms are connected to the control cabinet through electrical lines, and the control cabinet provides them with working power.

[0062] Working principle:

[0063] First, loosen the locking bolt 1010 along the threaded locking through hole 1016 through a tool, and then adjust the position of the operation monitoring mechanism along the reciprocating adjustment base 5 through the sliding insertion of the limiting plug block 103 and the limiting slot 501, so that the pressure plate 2 moves to a position area close to the side of the conveyor belt. When the position adjustment is completed, tighten the locking bolt 1010 along the threaded locking through hole 1016 through a tool, so that the stud end of the locking bolt 1010 is tightly attached to the bottom surface of the inner end of the limiting slot 501, thereby fixing the current position of the operation monitoring mechanism;

[0064] Furthermore, according to the monitoring distance interval requirements, a plurality of reciprocating adjustment bases 5 can be welded on the frame of the belt conveyor 4, and a set of operation monitoring mechanisms are slidably mounted on each reciprocating adjustment base 5. In order to ensure the accuracy of the deviation monitoring, when the pressure plate 2 in the previous set of operation monitoring mechanisms moves to a position area close to the side edge (right side) of the conveyor belt, the pressure plate 2 in the adjacent set of operation monitoring mechanisms moves to a position area close to the side edge (left side) of the conveyor belt, so as to ensure the accuracy of the deviation monitoring;

[0065] The gold ore after blasting mining is loaded by a loader or excavator onto the feed end of the belt conveyor 4 and conveying is started. During the conveying process, the ultrasonic level meter 106 starts to monitor the height of the ore on the conveyor belt in real time, and the level threshold is set according to the bandwidth of the belt conveyor 4. During the conveying process, if the ultrasonic level meter 106 detects that the material height exceeds the preset threshold, it is determined to be overloaded. The ultrasonic level meter 106 feedback signal is given to the microcontroller 1018, and the microcontroller 1018 controls the overload sound and light alarm 105 to start, so as to realize overload warning, so that the staff can go to handle it in time.

[0066] When the conveyor belt deviates due to factors such as material overload, the edge of the conveyor belt presses the pressure plate 2, causing the silicone contact block 203 to press the deviation warning switch 1011, putting it in a pressed start state. The switch sends a feedback signal to the microcontroller 1018, which controls the overload sound and light alarm 105 to start, thereby providing a deviation warning and facilitating timely processing by staff.

[0067] In order to ensure that the above functions can play a corresponding warning role during the transportation process, the present invention is provided with a periodic fault detection to detect whether the ultrasonic level meter 106, the overload sound and light alarm 105, the deviation warning switch 1011 and the deviation sound and light alarm 104 are faulty. The specific operation is as follows:

[0068] First, based on the periodic fault detection requirements for the ultrasonic level meter 106, the overload sound and light alarm 105, the deviation warning switch 1011, and the deviation sound and light alarm 104, the timing value of the operation monitoring timing module 1017 is set. For example, if the periodic fault detection of the ultrasonic level meter 106, the overload sound and light alarm 105, the deviation warning switch 1011, and the deviation sound and light alarm 104 is performed once every hour, the timing value of the operation monitoring timing module 1017 is set to one hour.

[0069] When the timing value of the operation monitoring timing module 1017 is reached, the operation monitoring timing module 1017 feeds back a signal to the microcontroller 1018, and the microcontroller 1018 controls the motor 108 to start, and the shaft end controls the incomplete gear 109 to rotate counterclockwise for one circle;

[0070] During the counterclockwise rotation of the incomplete gear 109, the incomplete gear 109 meshes with the transmission gear teeth 305 to drive the reciprocating slider 303 to move to the right. During the movement, the reciprocating slider 303 moves to the right along the reciprocating opening 1013 through the sliding connection between the guide socket 304 and the guide rod 1014, and the return spring a1015 is gradually compressed. At the same time, the reciprocating slide 3 moves to the right synchronously. Based on the rightward movement of the reciprocating slide 3, the pressure block 301 gradually approaches the pressure plate 2, and the monitoring cooperation opening 302 also gradually breaks away from the position corresponding to the monitoring end of the ultrasonic level meter 106. When the incomplete gear 109 is about to disengage from the gear teeth 305, the monitoring cooperation opening 302 is gradually separated from the monitoring end of the ultrasonic level meter 106. The closing opening 302 is staggered with the monitoring end of the ultrasonic level meter 106, and the reciprocating slide 3 blocks the monitoring end of the ultrasonic level meter 106. Therefore, based on the blocking of the reciprocating slide 3, an overload state is simulated, so that the ultrasonic level meter 106 detects that the material height exceeds the preset threshold value. If the ultrasonic level meter 106 and the overload sound and light alarm 105 are both in normal operation, the overload sound and light alarm 105 will start the alarm at this time. If the ultrasonic level meter 106 or the overload sound and light alarm 105 fails, the alarm cannot be realized in the specific time period. Based on this method, it is convenient for the staff to conduct unified observation in the specific time period to determine its operating status and whether it needs maintenance.

[0071] Similarly, when the incomplete gear 109 is about to disengage from the gear teeth 305, the pressing block 301 is pressed to move the pressing plate 2 to the right, and the silicone contact block 203 is pressed and contacted with the button end of the deviation warning switch 1011. The deviation warning switch 1011 is in a pressed and activated state, simulating a deviation state. If the deviation warning switch 1011 and the deviation sound and light alarm 104 are both in normal operating states, the deviation sound and light alarm 104 will start the alarm at this time. If the deviation warning switch 1011 or the deviation sound and light alarm 104 fails, the alarm cannot be realized in this specific time period. Based on this method, it is convenient for the staff to conduct unified observation in this specific time period to determine its operating state and whether it needs maintenance.

[0072] Furthermore, the overload sound and light alarm 105 and the deviation sound and light alarm 104 activated during the periodic fault detection process of the present invention are both temporarily activated. When the incomplete gear 109 is disengaged from the gear teeth 305, the return spring a1015 and the return spring b202 in the compressed state are quickly reset and rebound, thereby pushing the reciprocating slide 3 and the pressure plate 2 to return to their original positions, thereby automatically turning off the overload sound and light alarm 105 and the deviation sound and light alarm 104 in the activated state, ensuring that timely alarms can be achieved when overload or deviation occurs subsequently.
