[0002] Using mine cars to transport ore is a common way of transferring ore in the middle section of mines. In actual applications, multiple mine cars are usually combined, and connection devices are required to connect the mine cars. Existing connection devices usually need to be installed and disassembled manually. For example, the patent with the publication number CN217124802U provides a connection mechanism for coal mine cars, which includes a connecting rod and a buffer mechanism arranged on the connecting rod. Connecting blocks for connecting mine cars are arranged at both ends of the connecting rod. When using this connection mechanism, it is necessary to fix the connecting block to the mine car through the installation holes on the connecting block, and then use the buffer device to buffer and protect the connection position during the movement of the mine car.

[0003] Although the above method can play a role in connecting the mine cars, the fixing and disassembling process between the connecting block and the mine car is relatively cumbersome, time-consuming, and inefficient. In the current context of intelligent driverless mines, especially when further transporting ore through a cage, frequent connection and grouping of cars are required, and these inefficient and inconveniently controlled methods are no longer able to meet the requirements.

[0004] In view of this, it is necessary to design a controlled connection device for mine cars that can effectively control the connection method of mine cars to solve the above problems. Summary of the Utility Model

[0028] As Figure 1 shown, the present utility model provides a controlled connection device for mine cars, comprising a fixed connection assembly 32 and a controlled connection assembly; the fixed connection assembly 32 includes a first connector 11 for connecting with a first mine car, a second connector 12 for connecting with a second mine car, and a connector 13 connecting the first connector 11 and the second connector 12; the controlled connection assembly includes a connecting pin 21, a fixing member 22 disposed above the first connector 11, an electromagnet 23 disposed on the upper part of the fixing member 22, and a power connection assembly connected to the electromagnet 23; the connecting pin 21 vertically penetrates through the electromagnet 23, the fixing member 22 and the first connector 11, the connecting pin 21 is connected to the fixing member 22 through a first spring 25 that can expand and contract in the vertical direction, a magnetic member 26 is disposed on the connecting pin 21, and the magnetic member 26 is located below the electromagnet 23.

[0029] In the above manner, the position of the connecting pin 21 can be efficiently controlled by the energized state of the electromagnet 23. When the electromagnet 23 is not energized, the connecting pin 21 is naturally inserted into the first connector 11 under the action of the first spring 25, enabling the effective connection of the mine cars; when the electromagnet 23 is energized, a magnetic field can be generated to lift the magnetic member 26 in the connecting pin 21, driving the connecting pin 21 to move upward, and the mine cars can be disengaged, thereby realizing the controlled connection of the mine cars and effectively improving the connection efficiency of the mine cars.

[0030] More specifically, please refer to Figures 2-3, in some embodiments of the present utility model, the first mine car is connected to the first connecting member 11 through the first mine car connecting portion 41, and the second mine car is connected to the second connecting member 12 through the second mine car connecting portion 42. Through holes penetrating up and down are provided in the first connecting member 11, the second connecting member 12, the first mine car connecting portion 41, and the second mine car connecting portion 42. Among them, the first connecting member 11 and the first mine car connecting portion 41 are controllably connected through a controlled connection assembly. When the connecting pin 21 simultaneously penetrates the through holes in the first connecting member 11 and the first mine car connecting portion 41, it indicates that the connection between the first connecting member 11 and the first mine car connecting portion 41 is successful. When the connecting pin 21 fails to penetrate the through hole in the first mine car connecting portion 41, it indicates that the first connecting member 11 and the first mine car connecting portion 41 are disengaged from each other. The second connecting member 12 and the second mine car connecting portion 42 are connected through a fixed connection assembly 32; the fixed connection assembly 32 can be a conventional bolt and nut assembly or other similar structures, and it is sufficient to be able to penetrate the through holes in the second connecting member 12 and the second mine car connecting portion 42 to connect the two, and all belong to the protection scope of the present utility model. Based on this setting method, the second connecting member 12 and the second mine car connecting portion 42 can be first connected by the fixed connection assembly 32, and then only the energization state of the electromagnet 23 in the controlled connection assembly needs to be adjusted to effectively control the connection state of the two mine cars, and the use process is relatively convenient.

[0031] Preferably, in some embodiments of the present utility model, a deviation correction spring 31 connected to the fixed connection assembly 32 is provided on the first connecting rod 131. The deviation correction spring 31 is sleeved on the outer side of the first connecting rod 131, and the diameter of the deviation correction spring 31 gradually increases along the axial direction; the end with a smaller diameter of the deviation correction spring 31 is connected to the first connecting rod 131, and the end with a larger diameter is connected to the fixed connection assembly 32. With this setting, a certain degree of offset and misalignment between the two mine cars can be allowed, effectively improving the tolerance of the device and ensuring the stability of the connection.

[0032] In an embodiment of the present utility model, the magnetic attracting member 26 refers to any structure that can be attracted by a magnetic field, preferably made of iron material; the top end of the first spring 25 is fixed on the bottom surface of the fixing member 22, the bottom end of the first spring 25 is fixed on the connecting pin 21, and the axial length of the first spring 25, the axial length of the connecting pin 21, and the position of the magnetic attracting member 26 can all be adjusted according to actual needs, so that the bottom end of the connecting pin 21 can penetrate the through hole of the first mine car connecting portion 41 when the electromagnet 23 is not powered on, and the bottom end of the connecting pin 21 can be separated from the through hole of the first mine car connecting portion 41 after the connecting pin 21 moves upward when the electromagnet 23 is powered on. Preferably, the magnetic attracting member 26 is arranged in the middle of the connecting pin 21 and penetrates the connecting pin 21 along the radial direction of the connecting pin 21. With such an arrangement, in the initial state when the electromagnet 23 is not powered on, the bottom end of the connecting pin 21 can penetrate the through hole of the first mine car connecting portion 41, so that the first mine car is connected to the first connecting member 11; when the electromagnet 23 is powered on to generate a magnetic field, the magnetic attracting member 26 can drive the entire connecting pin 21 to move upward evenly and compress the first spring 25. When the bottom end of the connecting pin 21 is separated from the through hole of the first mine car connecting portion 41, the separation of the mine car is completed.

[0033] Preferably, in some embodiments of the present utility model, the side of the bottom of the connecting pin 21 facing the first mine car is provided with an inclined surface 211. With such an arrangement, when the first mine car connecting portion 41 presses against the inclined surface 211, the inclined surface 211 can drive the entire connecting pin 21 to move upward and compress the first spring 25. Until the first mine car connecting portion 41 passes through the position where the inclined surface 211 is located, under the action of the first spring 25 and the gravity of the connecting pin 21 itself, the connecting pin 21 moves downward to restore the initial state. At this time, the bottom end of the connecting pin 21 can penetrate the through hole of the first mine car connecting portion 41, thereby realizing the automatic connection between the first mine car and the first connecting member 11.

[0034] In an embodiment of the present utility model, the power connection assembly can be any assembly that can supply power to the electromagnet 23 and can be selected according to actual needs. Specifically, in some embodiments of the present utility model, the power connection assembly includes a power connection tentacle 24 and a circuit connecting the power connection tentacle 24 and the electromagnet 23. Among them, the power connection tentacle 24 can be connected to a pantograph or other power supply devices in the mine car and supply power to the electromagnet 23 through the circuit. The power connection tentacle 24 can be connected to the connector 13, and the circuit can be arranged outside or inside the connector 13.

[0035] Preferably, in an embodiment of the present utility model, the connector 13 includes a first connecting rod 131 with two ends respectively connected to the first connecting member 11 and the second connecting member 12, a second connecting rod 132 connected to the fixing member 22 and the first connecting rod 131, and a third connecting rod 133 for connecting the first connecting rod 131 and the power receiving contact 24. The third connecting rod 133 is vertically disposed at the bottom of the first connecting rod 131, and one end of the power receiving contact 24 is rotatably connected to the bottom of the third connecting rod 133. A second spring 27 for limiting is provided between the power receiving contact 24 and the first connecting rod. With such a setting, during actual use, it is convenient to adjust the position of the power receiving contact 24 to a certain extent when connecting to a pantograph or other power supply devices. Among them, the first connecting rod 131, the second connecting rod 132, and the third connecting rod 133 can be an integrally formed overall structure. The second connecting rod 132 and the third connecting rod 133 are preferably hollow structures passing through the first connecting rod 131, so as to arrange the lines connecting the connecting electromagnet 23 and the power receiving contact 24 inside the second connecting rod 132 and the third connecting rod 133. A cavity communicating with the electromagnet 23 and the second connecting rod 132 can also be provided in the fixing member 22 as needed to accommodate the corresponding lines.

[0036] The working principle of the mine car controlled connection device provided by the present utility model will be described below:

[0037] When the mine car controlled connection device provided by the present utility model is in use, first use the fixed connection assembly 32 to connect the second connecting member 12 with the second mine car connection part 42 to complete the connection of the connection device with the second mine car. Then, when it is necessary to further connect the first mine car, by adjusting the position of the first mine car, moving the first mine car connection part 41 to the inclined surface 211 position and continuing to move in the direction of pressing the inclined surface 211, the connection pin 21 can be moved upward. After the first mine car connection part 41 passes through the position where the inclined surface 211 is located, the connection pin 21 then falls back to the initial position. At this time, the bottom end of the connection pin 21 penetrates the through hole of the first mine car connection part 41, completing the automatic connection of the first mine car and the connection device, and realizing the efficient connection between the first mine car and the second mine car.

[0038] When it is necessary to disconnect the first mine car from the second mine car, by bringing the power supply end of the pantograph or other power supply devices of the mine car into contact with the power receiving contact 24 to supply power to the electromagnet 23, a magnetic field is generated, causing the magnetic component 26 in the connection pin 21 to move upward, and then driving the connection pin 21 to move upward and compress the first spring 25. At this time, the bottom end of the connection pin 21 disengages from the through hole of the first mine car connection part 41, enabling the first mine car to move freely, and completing the disconnection between the first mine car and the second mine car.

[0039] In the above manner, the utility model can efficiently control the position of the connecting pin 21 by the energized state of the electromagnet 23, thereby realizing the controlled connection of the mine car, so as to quickly carry out the autonomous connection and disconnection of the mine car, effectively improving the connection efficiency of the mine car, and the overall structure is simple and easy to maintain, having a good application prospect.

[0040] The above embodiments are only used to illustrate the technical solutions of the utility model and not to limit them. Although the utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the utility model can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the utility model.
