Technical Field
[0001] The utility model relates to the technical field of intelligent control, in particular to an automatic ore-feeding device for cooperative operation of a mine electric locomotive and a vibrating ore-feeding machine. Background Art
[0002] Mining electric locomotives are the main mode of mine transportation in my country. The entire transportation system consists of ore dischargers, transport tracks, mining electric locomotives, mine cars, unloading stations, microcomputer interlocking systems and other auxiliary equipment. Mining electric locomotives can be used in underground and open-pit mines. Mining electric locomotives usually carry multiple mine cars, load ore from the ore discharge station, transport the ore to the unloading station through the transport track, and then transfer it to the ore dressing plant. The output of underground mines is small, and usually there are only one or two vibrating ore dischargers at the ore discharge station. The output of open-pit mines is large. In order to improve transportation efficiency, each ore discharge point has multiple vibrating ore dischargers. Eighteen vibrating ore dischargers on a single ore discharge track in a mine can discharge ore from six mine cars at the same time. Three operators are required to work in coordination with the mine electric locomotive driver during operation. The repeated communication between the electric locomotive driver and the ore discharger can align the position. When the position is not aligned, it is easy to cause various situations such as spilling ore and full ore. Since there are gaps between the material piles formed on the mine cars, ore needs to be replenished, and frequent alignment is required when replenishing ore, resulting in low production efficiency.
[0003] At present, major mines are gradually promoting remote control or unmanned driving of electric locomotives. However, it is still difficult to realize that 18 vibrating ore-discharging machines can simultaneously discharge ore into six mine cars by remote control alone. It is difficult to align the mine cars and vibrating ore-discharging machines at the same time, and it is not feasible to remotely control 18 vibrating ore-discharging machines at the same time.

After the mine electric locomotive 11 detects the positioning device 19, it reduces the running speed. The positioning device 15 starts to detect the alignment of the mine car 12 and the vibrating ore discharger 13. The positioning device 15 is used to detect whether the head and tail mine car 12 is located in the operating area of the vibrating ore discharger 13. When the mine electric locomotive 11 and the mine car 12 pass the positioning device 15, the detection The signal light is off, and the detection signal light of the positioning device 15 is on when there is no obstruction. When at least three detection signal lights of the head and tail positioning device 15 are on, the mine car 12 and the vibrating ore-dumping machine 13 are successfully aligned. After the alignment is successful, the mine electric locomotive 11 brakes and stops to prepare for loading ore. When the alignment is unsuccessful, the mine electric locomotive 11 moves forward or backward to fine-tune and align again.

When the alignment is successful, the detection signal is fed back to the control center. The control center operator can monitor whether the mine car 12 is successfully aligned with the vibrating ore discharger 13 through the detection signal of the positioning device 15, and confirm whether automatic ore discharge is allowed. The vibrating ore discharger 13 can be controlled separately. Once an emergency occurs, it can be controlled to stop at the same time or separately. After the vibrating ore discharger 13 is aligned with the mine car 12, the control center gives an automatic ore discharge instruction. During automatic ore discharge, multiple vibrating ore dischargers 13 discharge ore into the mine car 12 at the same time. The material level detection device 14 detects After the material level reaches the standard, the ore discharge is stopped. The material level detection device 14 and the timer control the vibration ore discharger 13 to stop in parallel. The first detection point of the material level detection device 14 warns that the material pile 21 is about to reach the standard. The second detection point is used to feedback that the material pile 21 has reached the standard, and notify the control center to stop ore discharge. When the material pile 21 reaches the standard or the timer expires, the automatic ore discharge can be stopped to avoid ore spillage caused by a failure of the material level detection device 14. When a certain material level detection device 14 fails, the mining electric locomotive 11 pulls the empty mine car 12 to the normal state.

[0021] The material level detection device 14 is located behind the vibrating ore drawer 13 to prevent the ore and the vibrating ore drawer 13 from interfering with it.
[0022] In view of the problems existing in the prior art, the utility model provides an automatic ore-feeding device for a mine electric locomotive and a vibrating ore-feeding machine in cooperation with each other. The mine electric locomotive 11 pulls the mine car 12 to run at a low speed and cooperates with the positioning device 15 and the positioning device 19. The positioning device 19 is used to judge whether the mine electric locomotive 11 has reached the positioning position. After the mine electric locomotive 11 detects the positioning device 19, the running speed is reduced. The positioning device 15 starts to detect the alignment of the mine car 12 and the vibrating ore-feeding machine 13. The positioning device 15 is used to detect whether the head and tail mine cars 12 are located in the operating area of the vibrating ore-feeding machine 13. When the mine electric locomotive 11 and the mine car 12 pass the positioning device 15, the detection signal light goes out and there is no shielding. When the head and tail alignment device 15 detects the signal light, when at least three detection signal lights of the head and tail alignment device 15 are on, the mine car 12 and the vibrating ore-feeding machine 13 are aligned successfully, and after the alignment is successful, the mine electric locomotive 11 brakes and stops to prepare for loading ore. When the alignment is unsuccessful, the mine electric locomotive 11 moves forward or backward to fine-tune and align again.

When the alignment is successful, the detection signal is fed back to the control center, and the control center operator uses the alignment device 1 5. The detection signal can monitor whether the mine car 12 is aligned with the vibrating ore-feeding machine 13 successfully and confirm whether automatic ore-feeding is allowed. The vibrating ore-feeding machine 13 can be controlled separately. In case of an emergency, it can be controlled to stop at the same time or separately. After the vibrating ore-feeding machine 13 is aligned with the mine car 12, the control center gives an automatic ore-feeding instruction. During automatic ore-feeding, multiple vibrating ore-feeding machines 13 simultaneously feed ore to the mine car 12. The material level detection device 14 stops feeding ore after detecting that the material level meets the standard. The material level detection device 14 and the timer control the vibration ore-feeding machine 13 to stop in parallel. The first detection point of the material level detection device 14 warns that the material pile 21 is about to meet the standard, and the second detection point is used to feedback the material pile. 21 meets the standard, notify the control center to stop ore discharge, and automatic ore discharge can be stopped when the material pile 21 meets the standard or the timer expires to avoid ore spillage caused by a failure of the material level detection device 14. When a certain material level detection device 14 fails, the mining electric locomotive 11 pulls the empty mine car 12 to the normal state. The vibrating ore discharger 13 corresponding to the material level detection device 14 discharges ore. The mining electric locomotive 11 and the vibrating ore discharger 13 cooperate with the automatic ore discharge device to realize that multiple vibrating ore dischargers 13 can automatically discharge ore to multiple mine cars 12 at the same time. The mining electric locomotive 11 and the vibrating ore discharger 13 do not require personnel to operate on site, realizing less-manned or even unmanned on-site operations.
[0023] Working principle:
[0024] In the first step, the mining electric locomotive 11 communicates with the positioning device 19 to calibrate the position of the mining electric locomotive 11. The mining electric locomotive 11 judges the operation instruction of the position according to the positioning device 19. When entering the area of the vibrating ore discharger 13, the mining electric locomotive 11 pulls the mine car 12 to run at a low speed and cooperates with the positioning device 15 and the positioning device 19. The positioning device 19 is used to judge whether the mining electric locomotive 11 has reached the positioning position. After the mining electric locomotive 11 detects the positioning device 19, it reduces the running speed, and the positioning device 15 starts to detect the mine car 12. Aligned with the vibrating ore discharger 13, the alignment device 15 is used to detect whether the head and tail mine cars 12 are located in the operating area of the vibrating ore discharger 13. When the mining electric locomotive 11 and the mine car 12 pass the alignment device 15, the detection signal light goes out. When there is no obstruction, the detection signal light of the alignment device 15 is on. When at least three detection signal lights of the head and tail alignment device 15 are on, the mine car 12 and the vibrating ore discharger 13 are successfully aligned. After the alignment is successful, the mining electric locomotive 11 brakes and stops to prepare for loading ore. If the alignment is unsuccessful, the mining electric locomotive 11 moves forward or backward to fine-tune and align again.
[0025] In the second step, when the alignment is successful, the detection signal is fed back to the control center. The control center operator can monitor whether the mine car 12 is aligned with the vibrating ore-feeding machine 13 through the detection signal of the alignment device 15, and confirm whether automatic ore discharge is allowed. The vibrating ore-feeding machine 13 has a general control, and the vibrating ore-feeding machine 13 can also be controlled separately. In case of an emergency, it can be controlled to stop at the same time or individually. After the vibrating ore-feeding machine 13 is aligned with the mine car 12, the control center gives an automatic ore discharge instruction. During automatic ore discharge, multiple vibrating ore-feeding machines 13 discharge ore into the mine car 12 at the same time. The material level detection device 14 stops discharging ore after detecting that the material level meets the standard. The material level detection device 14 controls the vibrating ore-feeding machine in parallel with the timer. 13 shuts down, the first detection point of the material level detection device 14 warns that the material pile 21 is about to meet the standard, and the second detection point is used to feedback that the material pile 21 meets the standard, and inform the control center to stop ore discharge. When the material pile 21 meets the standard or the timer expires, the automatic ore discharge can be stopped to avoid ore spillage caused by a failure of the material level detection device 14. When a certain material level detection device 14 fails, the mining electric locomotive 11 pulls the empty ore car 12 to the normal state. The vibrating ore discharger 13 corresponding to the material level detection device 14 discharges ore. When all the material piles 21 meet the standard, the ore replenishment program is started. When the mining electric locomotive 11 pulls the ore car 12 to resume alignment, the ore replenishment program is started to automatically replenish ore to fill the gaps between the material piles 21 to improve the loading quality.
