Detailed Description

Referring to fig. 1-3, wherein fig. 1-3 respectively show a front view, a left side view, and a top view of a mine hoist control system according to an embodiment of the present invention. As can be seen from the attached drawings 1-3, the embodiment of the utility model provides a mine hoisting control system includes feed bin conveyer belt 1, coal conveyer belt 2, action wheel 3, follows driving wheel 4, stop device 6, feed bin 7 and control cabinet 11 etc.. The console 11 is a component for controlling the automatic operation of the mine hoist control system. For the convenience of operation and personal safety of operators, the console 11 is arranged on the ground surface or on the parts such as the bin conveyor 1 arranged on the ground surface, which can be specifically arranged according to actual production and environmental conditions.

Specifically, the bunker conveyor 1 is partially located above the ground surface, and the rest is located in the mine shaft, so as to lift coal from the underground to the ground surface. In order to save equipment cost and space occupation, the end part of the bin conveyor belt 1 is positioned above the ground surface, and the rest part is positioned in the mine tunnel. The coal conveyor belt 2 is a component which is matched with the bin conveyor belt 1 to transport coal and is positioned above the ground surface. After the bunker conveyor belt 1 lifts the coal to the ground surface, the coal is dumped on the coal conveyor belt 2 and then conveyed to a coal storage place or directly loaded by the coal conveyor belt 2.

The bin conveyor belt 1 is annular, and a gear or a thread is arranged in the annular interior of the bin conveyor belt. The driving wheel 3 and the driven wheel 4 are also provided with gears or threads on the outer portions, and the driving wheel 3 and the driven wheel 4 are respectively meshed with the bin conveyor belt 1. In addition, the driving wheel 3 is also connected with the driving motor 5, so that when the driving motor 5 works, the driving wheel 3 can be driven to rotate, and then the bin conveyor belt 1 is driven to convey. In the present embodiment, the driving motor 5 is connected to a console 11 provided above the ground surface, whereby the driving motor 5 is operated and stopped by the console 11, as shown in fig. 4.

Referring to fig. 5, fig. 5 shows an enlarged schematic view of a portion a of fig. 1. As shown in fig. 5, in the embodiment of the present application, in order to provide the storage bin 7 on the storage bin conveyor belt 1, a plurality of position-limiting devices 6 are disposed on the storage bin conveyor belt 1, and the position-limiting devices 6 can rotate on the storage bin conveyor belt 1 in situ. Specifically, the limiting device 6 includes a first servo drive motor 601 and a rotating plate 602 disposed on the bin conveyor belt 1, and the first servo drive motor 601 is further connected to the console 11, so that the operation and the shutdown of the first servo drive motor 601 are realized through the console 11. When the first servo driving motor 601 rotates, the rotating plate 602 can be driven to rotate by a certain angle, and the rotating angle can be set according to actual conditions. In order to facilitate the arrangement of the first servo driving motor 601 and the first servo driving motor 601 to drive the rotation plate 602 to rotate, the first servo driving motor 601 is located at the center of the rotation plate 602.

The opposite two sides of the rotating plate 602 are respectively provided with a slide block 603, and the slide groove 8 on the side wall of the bin 7 can slide along the slide block 603, so that the connection between the bin 7 and the limiting device 6 is realized. When the feed bin 7 moves from bottom to top, because the spout 8 can slide along the slider 603, that is, the feed bin 7 can slide along the slider 603, therefore, under the effect of the gravity of the feed bin 7, the slider 603 at this moment is located at the top of the feed bin 7. When the magazine conveyor 1 conveys the magazine 7 to the highest position of the magazine conveyor 1, the magazine 7 assumes a horizontal state. The bin conveyor belt 1 continues to drive, and the bin 7 slides downwards under the action of self gravity, namely the sliding chute 8 slides along the sliding block 603, and at the moment, the sliding block 603 is positioned at the bottom of the bin 7. Thus, the magazine 7 can be turned over by the chute 8, the slider 603, and the own weight of the magazine 7.

Further, because the rotating plate 602 is provided with the bin 7, when the first servo driving motor 601 drives the rotating plate 602 to rotate by a certain angle, the bin 7 also correspondingly rotates by a certain angle, and then the coal is dumped onto the coal conveyor belt 2, so that the coal is discharged.

Referring to fig. 6, fig. 6 shows a schematic structural diagram of a storage bin in an embodiment of the present application. As can be seen from fig. 6, in the present embodiment, the bunker 7 is a container for coal mines. The bin 7 is suspended from the bin conveyor belt 1 by a limiting device 6. The storage bin 7 comprises two movable cover plates 701, a bottom plate 702, a first side plate 703, a second side plate 704, a third side plate 705 and a fourth side plate 706 which are sequentially enclosed into a square. Specifically, the first side plate 703, the second side plate 704, the third side plate 705, and the fourth side plate 706 enclose a square to form a frame of the silo 7. The square frame is provided with two removable lids 701 at the top and a bottom plate 702 at the bottom, thereby forming a silo 7.

The second side plate 704 and the fourth side plate 706 are both provided with a sliding groove 8, so that the sliding grooves 8 can be arranged on the sliding blocks 603 in the limiting device 6 in a sliding manner. The two movable cover plates 701 are respectively movably arranged at the top ends of the first side plate 703 and the third side plate 705, and the two movable cover plates 701 are oppositely closed, namely, the top of the storage bin 7 can be completely blocked when the two movable cover plates 701 are buckled. In the present embodiment, when the removable cover 701 is opened, coal is charged through the removable cover 701. To facilitate automatic control of opening and closing of the flip boards 701, two flip boards 701 are respectively disposed on top ends of the first side board 703 and the third side board 705 through a first rotation shaft (not shown in the figure). In order to control the rotation of the first rotating shaft, a second servo driving motor 707 is further disposed on the bin 7. The second servo drive motors 707 are electrically connected to the two first rotary shafts, respectively, and the second servo drive motors 707 are connected to the console 11, whereby the rotation control of the two first rotary shafts is realized by the console 11.

Further, as shown in fig. 6 and 7, the bottom end of the side plate of the bunker 7 facing the coal conveyor belt 2 is provided with a light emitter 9, and the coal conveyor belt 2 is provided with a light receiver 10. Namely, the light emitter 9 is arranged at the bottom end of the fourth side plate 706, and the coal conveyor belt 2 is provided with the light receiver 10. The light emitter 9 and the light receiver 10 are further respectively connected with the console 11, so that the console 11 receives signals, controls the stopping of the bin conveyor belt 1, controls the rotation of the limiting device 6 and the like. Specifically, when the storage bin 7 runs from bottom to top, after the light emitted by the light emitter 9 is received by the light receiver 10, the light receiver 10 sends a receiving signal to the console 11. The control console 11 controls the bin conveyor belt 1 to stop running according to the received signal, and controls the limiting device 6 to rotate after the bin conveyor belt 1 stops running.

To facilitate the dumping of coal by the bunker 7, the bottom plate 702 in the embodiment of the present application is movably attached to the square frame. Specifically, the bottom plate 702 is disposed at the bottom end of the second side plate 704 through the second rotation shaft. In order to control the opening and closing of the bottom plate 702, a third servo driving motor 708 connected with the console 11 is further disposed on the storage bin 7, and the third servo driving motor 708 is further electrically connected with the second rotating shaft. In addition, in the mine lifting process, not only can the lifting and the transportation of coal be realized, but also the transportation of personnel, equipment and the like to the underground can be realized, so that when the emptied stock bin 7 descends, the bottom plate 702 of the stock bin can be opened, and the movable cover plate 701 is closed.

The working process of the mine hoisting control system provided by the embodiment of the application is as follows: the console 11 controls the second servo driving motor 707 to rotate, so as to drive the two movable cover plates 701 to open, so that the coal filling is realized through the movable cover plates 701. After coal is filled in the stock bin 7, the control console 11 controls the driving motor 5 to drive the driving wheel 3 to rotate, so that the stock bin conveying belt 1 rotates, and then the stock bin 7 is driven to move from bottom to top. At this time, the sliding block 603 is on the top of the bin 7, i.e., at the end of the chute 8 near the removable cover 701. When the light emitted from the light emitter 9 is received by the light receiver 10 during the movement of the silo 7, the light receiver 10 transmits a receiving signal to the console 11. At this time, the console 11 controls the driving motor 5 to stop rotating. After the driving motor 5 stops rotating, the console 11 controls the first servo driving motor 601 to rotate a certain angle, and further the storage bin 7 rotates the same angle under the action of the rotating plate 602 and the sliding block 603. At this time, the magazine 7 assumes an inclined state. The console 11 controls the third servo driving motor 708 to rotate, so as to drive the bottom plate 702 to rotate around the second rotation axis. At this time, the bunker 7 is in an open state, and coal is discharged onto the coal conveyor belt 2 through the bottom plate 702, so that the automatic control of lifting, discharging and conveying of the coal is realized.

After the coal is discharged, the control console 11 controls the driving motor 5 to rotate, and then the bin conveyor belt 1 continues to transmit. At this time, the bin 7 also continues to rise. When the silo 7 rises to the top of the silo conveyor 1, the silo 7 is horizontal. When the bin conveyor 1 continues to drive, the chute 8 slides along the slide block 603 under the gravity of the bin 7, and at this time, the slide block 603 gradually approaches the bottom plate 702 of the bin 7. When the magazine 7 is completely inverted, the slide 603 is located at the end of the slide 8 near the bottom plate 702. At this time, a person, a loading device, or the like may be placed in the bin 7.

Because be provided with a plurality of silos on the feed bin conveyer belt in this application, therefore can promote a large amount of coals simultaneously, improve the lifting efficiency.
