[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] The core of this invention is to provide a mining power supply device that can automatically perform cable winding and unwinding switching operations without relying on manual labor, thus achieving intelligent cable winding and unwinding switching operations. Another core aspect of this invention is to provide a mining system that includes the aforementioned mining power supply device.

[0033] The mining power supply device provided by this utility model includes a cable car 1, a monitoring component, a power supply station 3, and control elements. Please refer to the following for details. Figure 1 , Figure 2 .

[0034] The cable car 1 includes a main body 12, a first cable drum 11 and a second cable drum 13 located on both sides of the main body 12, and a power supply station 3 connected to the first cable drum 11 and the second cable drum 13 to provide cables. In actual mining operations, the main body 12 can move, and the first cable drum 11 and the second cable drum 13 can rotate to realize cable winding or unwinding operations.

[0035] The cable car 1 can travel along the belt conveyor 9. The cable set on the cable car is wound on the first cable drum 11 and the second cable drum 13. One end is connected to the power supply station 3 and the other end is connected to the electrical equipment, which can be mining equipment such as the coal mining machine 7, the loader, and the transfer machine 8.

[0036] Monitoring areas 2 are formed on both sides of the power supply station 3 along the travel direction of the main body 12. Specifically, monitoring areas 2 can be the areas formed by extending the power supply station 3 along both sides of the travel direction of the main body 12. The main body 12 of the cable reel 1 can move into or out of this monitoring area 2. The position information of the main body 12 can be automatically obtained through the monitoring components. The position information is analyzed by the control element to determine whether the main body 12 is within the monitoring area 2, so as to switch the cable winding and unwinding operation.

[0037] The monitoring component can also monitor the direction of travel of the main body 12, so as to determine whether the direction of travel of the main body 12 has changed through the control element, so as to switch the cable laying and winding operation.

[0038] In one specific embodiment, the component capable of monitoring the position information of the main body 12 can be a position sensor installed on the main body 12. When the main body 12 is moving, the position of the main body 12 can be acquired in real time through the position sensor. Based on this position information and the position information of the monitoring area 2, it can be determined whether the main body 12 is within the monitoring area 2, thus determining whether a switch for cable deployment / retraction is required. In this specific embodiment, the position of the monitoring area 2 is relatively constant, and the corresponding position information of the power supply station 3 is fixed. Therefore, the relative positional relationship between the main body 12 and the monitoring area 2 can be determined based on the monitoring information of the monitoring component and the position information of the monitoring area 2. However, in actual applications, if the entire power supply device or only the power supply station 3 needs to be transferred, the position information of the monitoring area 2 needs to be updated to ensure reliable determination of whether the main body 12 is within the monitoring area 2.

[0039] In one specific embodiment, the component capable of monitoring the position information of the main body 12 can be a component consisting of a receiver and a transceiver. Specifically, a receiver is installed on one of the power supply station 3 and the main body 12, and a transmitter is installed on the other. The transmitter transmits a signal to the receiver. When the receiver can receive the signal, it can feed back to the control element. Based on this, the control element can determine that the main body 12 has moved into the monitoring area 2. If the receiver does not receive the information, it means that the main body 12 has not moved into the monitoring area 2.

[0040] In one specific implementation, the component capable of monitoring the position information of the main body 12 may be a camera assembly installed on the main body 12. The camera assembly is positioned with its shooting surface facing the power station 3. By analyzing the photos taken by the camera assembly, if the power station 3 is captured, it indicates that the main body 12 has moved into the monitoring area 2; if it is not captured, it indicates that it has not moved into the monitoring area 2.

[0041] The above-described specific implementation can control the switching of cable laying and take-up operations by determining whether the main body 12 is located within the monitoring area 2. Specifically, the mode is switched when it is located within the monitoring area 2. For example, if the cable laying operation was performed before moving into the monitoring area 2, then the cable laying operation will be switched after moving into the monitoring area 2. The switching of cable laying and take-up operations is achieved by controlling the rotation direction of the first cable drum 11 and the second cable drum 13 through the control element.

[0042] In one specific implementation, the component used to detect the direction of travel of the main body 12 can be the steering angle sensor, positioning module sensor, etc. of the cable car 1 itself. It can determine whether the main body 12 has changed direction based on the sensor information obtained by the control element. If it changes direction, it is necessary to switch the cable winding and unwinding mode. However, it should be noted that if the main body 12 passes through the monitoring area 2 after changing direction, it is necessary to switch the mode again.

[0043] In this embodiment, the control element can be specifically the controller of the cable car 1, which directly utilizes the structure of the cable car 1 without adding extra design costs.

[0044] In this embodiment, by cooperating with the monitoring components and control elements, the cable winding and unwinding operations of the first cable drum 11 and the second cable drum 13 can be switched intelligently according to the position and direction of travel of the main body 12 during the movement of the cable car 1, so as to improve the automation and intelligence level of the cable winding and unwinding operations.

[0045] Based on the above embodiment, the monitoring component includes a laser target arranged in the power supply station 3 and a laser emitter arranged in the main body 12. The laser emitter is used to emit laser light towards the laser target. When the main body 12 of the cable car 1 moves into the monitoring area 2, the laser target is located in the emission path of the laser emitter.

[0046] When the main body 12 of the cable car 1 moves into the monitoring area 2, the laser emitter and the laser target are set opposite each other. The laser emitter shines on the laser target. At this time, the control element receives the feedback signal from the laser target. Combined with the current direction of travel of the main body 12, the control element can automatically control the switching of the cable winding / rewinding mode of the first cable drum 11 and the second cable drum 13.

[0047] By setting up a laser target and a laser emitter, the position information of the main body 12 can be obtained with a relatively simple structure, so as to reduce the design and processing cost of the mining power supply device. In the mining environment, the laser target and laser emitter have good applicability. As long as the laser can reach the position of the laser target, it means that the main body 12 has moved into the monitoring area 2, which can ensure the reliability of position detection.

[0048] In practical applications, if the mining location needs to be changed, the entire mining power supply device can be moved without updating the control program. It can be applied to the next mining location without modification, thus demonstrating good applicability.

[0049] In this embodiment, the position of the laser emitter on the main body 12 is not limited. It can be set on the side or top of the main body 12 so that when the main body 12 moves into the monitoring area 2, it can emit a laser to the power supply station 3 set opposite to it.

[0050] If the laser emitter is located at the top of the main body 12, and there is a certain height difference between the laser emitter and the laser target, the laser can be directed to the laser target by adjusting the emission direction.

[0051] Based on any of the above embodiments, the laser target is located in the middle of the side of the power supply station 3 near the main body 12, and the laser emitter is located in the middle of the side of the main body 12 near the power supply station 3.

[0052] The laser emitter is positioned on the main body 12 to avoid interfering with the cable winding and unwinding operations of the first cable reel 11 and the second cable reel 13, and to facilitate the connection between the laser emitter and the control elements on the main body 12. Furthermore, the laser emitter is positioned in the middle of the side of the main body 12 near the power supply station 3. When the main body 12 moves into the monitoring area 2 and the laser target and laser emitter are facing each other, the laser emitter can reliably emit laser light onto the laser target, ensuring the reliability of monitoring and thus guaranteeing the reliable and accurate switching of cable winding and unwinding modes.

[0053] If the main body 12 moves out of the monitoring area 2, that is, the laser target is no longer located in the emission area of ​​the laser emitter, in one case, the direction of travel of the main body 12 does not change, and the first cable drum 11 and the second cable drum 13 maintain the state after the switching of the monitoring area 2; in another case, the direction of travel of the main body 12 changes, and the first cable drum 11 and the second cable drum 13 switch to the opposite state to the state after the switching of the monitoring area 2. For example, if the state after the switching of the monitoring area 2 is cable laying, the first cable drum 11 and the second cable drum 13 switch to the cable winding state when the direction of travel of the main body 12 changes.

[0054] Based on any of the above embodiments, the monitoring component includes an imaging element arranged on the main body 12, and a control element signal connected to the imaging element.

[0055] The imaging element moves with the main body 12. When the main body 12 moves into the monitoring area 2, the power station 3 is within the imaging range of the imaging element, that is, the imaging element can capture the power station 3. If the captured image is consistent with the initial image stored in the control element or the consistency meets certain conditions, it means that the main body 12 has moved into the monitoring area 2 and the cable retraction mode can be switched.

[0056] It should be noted that the initial image stored in the control element is the image of the power station 3 that can be captured when the main body 12 is in the monitoring area 2. This image needs to be stored in advance so that the control element can compare it with the image captured in real time by the shooting element to determine whether the main body 12 has moved into the monitoring area 2.

[0057] Based on any of the above embodiments, please refer to Figure 1 and Figure 2 The first cable drum 11 and the second cable drum 13 are arranged on both sides of the main body 12 in the direction of travel.

[0058] When the main body 12 is located within the monitoring area 2, the main body 12 moves away from the monitoring area 2, and the control element controls the first cable drum 11 and the second cable drum 13 to release the cable; when the main body 12 is located outside the monitoring area 2, and the main body 12 moves from the direction away from the monitoring area 2 to the direction closer to the monitoring area 2, the control element controls the first cable drum 11 and the second cable drum 13 to retract the cable.

[0059] by Figure 1 For example, when the cable car 1 moves to the left and passes through the monitoring area 2, the laser emitter in the middle of the main body 12 shines on the laser target of the power supply station 3 and sends a feedback signal. After receiving the feedback signal, the control element on the main body 12 can determine that the main body 12 has moved into the monitoring area 2. Combined with the direction of travel of the main body 12 fed back by the monitoring component, it is determined that the cable car 1 is already in the middle area to the left. Then the control element controls the first cable drum 11 and the second cable drum 13 to be in the cable laying mode.

[0060] The main body 12 continues to move to the left. When the main body 12 changes direction on the left side of the area and moves to the right, the direction of travel changes and the main body 12 is outside the monitoring area 2. At this time, the control element controls the first cable drum 11 and the second cable drum 13 to be in the cable winding mode.

[0061] by Figure 2 For example, when the cable car 1 moves to the right and passes through the monitoring area 2, the laser emitter on the main body 12 shines on the laser target of the power supply station 3 and sends a feedback signal; after receiving the feedback signal, the control element on the main body 12 can determine that the main body 12 has moved into the monitoring area 2. Combined with the direction of travel of the main body 12 fed back by the monitoring component, it is determined that the cable car 1 is already in the middle area slightly to the right. The control element controls the first cable drum 11 and the second cable drum 13 to be in the cable laying mode.

[0062] The main body 12 continues to move to the right. When the cable car 1 changes its direction of travel to the left on the right side of the central area, the direction of travel changes and the main body 12 is outside the monitoring area 2. At this time, the control element controls the first cable drum 11 and the second cable drum 13 to be in the cable winding mode.

[0063] The above description is based on the example of the monitoring components at the monitoring position of the main body 12 including a laser target and a laser emitter. When the monitoring components at the monitoring position of the main body 12 are imaging elements, the process is the same as above, except that the monitoring method is different. The specific process will not be described in detail here.

[0064] In this embodiment, by controlling the regional mode and the direction of travel, the switching of the cable winding and unwinding mode can be automatically controlled, so that the cable reel 1 can intelligently wind and unwind the cable without human intervention, thereby improving the level of automation and intelligence.

[0065] Based on any of the above embodiments, the monitoring component further includes a vehicle feature acquisition module arranged on the main body 12, the feature acquisition module being used to acquire the travel direction of the main body 12.

[0066] The control element signal is connected to the vehicle feature acquisition module so that it can determine whether the travel direction of the main body 12 has changed based on the information obtained by the vehicle feature acquisition module.

[0067] In one implementation, the vehicle feature acquisition module can collect the relative speed of the vehicle and determine the direction of travel of the vehicle by using the relative speed determined by the coordinates obtained when detecting two adjacent positions of the vehicle while it is traveling, so as to determine whether the direction of travel of the main body 12 has changed.

[0068] In one implementation, the vehicle feature acquisition module can collect images taken at two adjacent positions while the vehicle is moving to determine the direction of the vehicle's movement, so as to determine whether the direction of the main body 12 has changed.

[0069] Based on any of the above embodiments, please refer to the figure. The width of the monitoring area 2 is equal to or greater than the width of the main body 12. The width direction of the monitoring area 2 and the width direction of the main body 12 are both parallel to the travel direction of the main body 12.

[0070] In this embodiment, by limiting the width of the monitoring area 2, the synchronous control of the first cable drum 11 and the second cable drum 13 on both sides is ensured when the main body 12 moves into the monitoring area 2, so as to avoid the monitoring of the position of the main body 12 being affected by the narrow monitoring area 2, and to ensure the reliability of the cable winding and unwinding operation control.

[0071] Based on any of the above embodiments, a substation 4 is also included. The input end of the substation 4 is connected to the main cable 5, and the output end of the substation 4 is connected to the first cable drum 11 and the second cable drum 13 via a branch cable 6.

[0072] In one specific implementation, to reduce current and voltage drop, the substation 4 is 10kV, and the 10kV 300² main cable 5 is laid flat from the surface high-voltage power supply station 3 into the pit. The output end of the substation 4 is connected to the first cable drum 11 and the second cable drum 13 via 240² and 70² branch cables 6, respectively, for use in introducing the coal mining machine 7 through the transfer conveyor 8 via the bridge, and for introducing the transfer conveyor 8 and the loader through permanent magnet switches, respectively.

[0073] Based on any of the above embodiments, a working area 10 corresponding to the working surface is also included, with a power supply station 3 and a monitoring area 2 disposed in the middle of the working area 10 along its length direction, and the length direction of the working area 10 being parallel to the travel direction of the main body 12.

[0074] In actual mining operations, the power supply station 3 is fixed within the work area 10, and the cable winding and unwinding operations are achieved by moving the cable reel 1 within the work area 10.

[0075] Specifically, such as Figure 1 and Figure 2 The thick arrows on the left and right sides indicate that the left-hand left and right-hand right are used for cable laying operations, while the left-hand right and right-hand left are used for cable retrieval operations. In this configuration, the intelligent control of the control elements enables the cable laying and retrieval operations to be automated without relying on manual operation.

[0076] In addition to the mining power supply device described above, this utility model also provides a mining system that includes the mining power supply device disclosed in the above embodiments. For the structure of other parts of the mining system, please refer to the prior art, which will not be described in detail here.

[0077] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0078] The above provides a detailed description of a mining power supply device and mining system provided by this utility model. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
