[0025] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0026] In the present disclosure, unless otherwise specified, directional words such as "top" and "bottom" used are the "top" and "bottom" of the present disclosure in the height direction when in use, and the "first direction" refers to the direction indicated by L1 in the drawings of the specification, and the "second direction" refers to the direction indicated by L2 in the drawings of the specification. In addition, the terms "first" and "second" used in the present disclosure are intended to distinguish one element from another and do not have order or importance. In addition, in the following description, when referring to the drawings, unless otherwise explained, the same figure marks in different drawings represent the same or similar elements. The above definitions are only used to explain and illustrate the present disclosure and should not be understood as limitations on the present disclosure.

[0027] According to a first aspect of the present disclosure, there is provided a connection assembly for a mining vehicle, Figures 1 to 5As shown in the figure, the connection assembly for the mine car includes: a connecting member 110, the connecting member 110 has a cylindrical longitudinal cross-section and has a first end 112 and a second end 113 arranged opposite to each other along a first direction, the connecting member 110 is provided with two connecting holes 111, the two connecting holes 111 are respectively located at the first end 112 and the second end 113 and are not connected to each other, the two connecting holes 111 are respectively used to adapt to the socket 211 of the connecting seat 210 of the first mine car and the socket 211 of the connecting seat 210 of the second mine car; and a plug-in member 120, the plug-in member 120 is plugged into the corresponding connecting hole 111 and the socket 211.

[0028] Through the above technical solution, in the connection assembly provided by the present disclosure, the connector 110 has a first end 112 and a second end 113 arranged opposite each other along the first direction. The connection hole 111 located at the first end 112 can be used to adapt to the socket 211 of the connection seat 210 of the first mine car, and the plug-in member 120 can be plugged into the above connection hole 111 and the socket 211. In this way, the first end 112 of the connector 110 can be connected to the first mine car, and similarly, the second end 113 of the connector 110 can also be connected to the second mine car. In summary, the connection assembly can connect the first mine car and the second mine car. In addition, the connector 110 has a cylindrical longitudinal cross-section, that is, the two end faces of the connector 110 that are opposite to each other along the first direction are both arcuate surfaces. In this way, when the first mine car and the second mine car turn, the arcuate surface of the connector 110 ensures that the connector 110 will not block the connection seat 210 of the first mine car or the second mine car, thereby preventing the first mine car or the second mine car from tipping over, and improving safety. In summary, the connection component can connect the mine car and is highly safe.

[0029] In the connection assembly provided by the present disclosure, the connection member 110 can be constructed in any suitable manner. As an exemplary embodiment, refer to Figures 2 to 4 As shown in , the annular space formed by the connector 110 can gradually decrease from the first end 112 and the second end 113 toward the middle of the connector 110. In this way, the connector 110 can be formed roughly into an "∞" shape or a gourd shape, so as to reduce the size of the connector 110 in a second direction perpendicular to the first direction while meeting safety requirements, thereby reducing the volume and weight of the connector 110.

[0030] In the connection assembly provided by the present disclosure, the plug connector 120 can be constructed in any suitable manner. As an exemplary embodiment, refer to Figure 1 and Figure 5As shown in , the connector 120 may include a plug rod 121 and a stopper 122. The plug rod 121 may be inserted into the corresponding connecting hole 111 and the plug hole 211. The stopper 122 may be connected to the plug rod 121 and used to stop at the connecting base 210 or the connector 110. In this way, when connecting the corresponding connecting hole 111 and the plug hole 211, the staff only needs to align the plug rod 121 with the connecting hole 111 and the plug hole 211, and then release the connector 120, which is convenient for operation. In addition, the stopper 122 stops at the connecting base 210 or the connector 110, so that the connector 120 can be prevented from falling from the connecting hole 111 and the plug hole 211, thereby ensuring the plugging effect of the connector 120, thereby improving the reliability of the connection assembly.

[0031] In the connection assembly provided by the present disclosure, the stopper 122 can be constructed in any suitable manner. As an exemplary embodiment, refer to Figure 1 and Figure 5 As shown in , the stopper 122 can be configured as a baffle, which can be connected to one end of the plug rod 121 and extend perpendicularly to the axial direction of the plug rod 121. The area of ​​the baffle is larger than the area of ​​the connecting hole 111 and the plug hole 211 to ensure that the baffle has a stopping effect on the plug connector 120.

[0032] In the connection assembly provided by the present disclosure, in order to further improve the reliability of the connection assembly, as an exemplary embodiment, reference is made to Figure 6 As shown in , the connection assembly may further include a stopper 300, which may be connected to and spaced apart from the connection base 210. The baffle may extend between the stopper 300 and the connection base 210 and be retained therebetween. In this way, the baffle can be retained by the stopper 300 and the connection base 210 on both sides along the height direction, respectively, to prevent the connector 120 from accidentally falling off due to the jolting of the mining car during operation. In summary, the provision of the stopper 300 can further enhance the reliability of the connection assembly.

[0033] In the connection assembly provided in the present disclosure, the limiting member 300 can be constructed in any suitable manner. As an exemplary embodiment, refer to Figure 6As shown in , the limiting member 300 can be constructed as a limiting ring with an opening 310 on one side, and the opening 310 can be used for the baffle to enter or leave the limiting space between the limiting ring and the connecting seat 210. Among them, the limiting space can be constructed as the area between the limiting ring and the connecting seat 210 along the height direction, and the setting of the opening 310 can facilitate the baffle to enter or leave the above-mentioned limiting space. Specifically. During the installation of the connector 120, the baffle can be aligned with the opening 310, and the connector 120 can be moved close to the connecting seat 210 until the baffle is arranged between the limiting ring and the connecting seat 210 along the height direction. At this time, the connector 120 is rotated around the axial direction of the connector rod 121 so that the baffle is arranged in the above-mentioned limiting space, thereby realizing the installation of the connector 120, and conversely, the connector 120 can be disassembled, which is easy to operate and does not require the aid of other tools.

[0034] The connection assembly may further include a connecting rod 400, the two ends of which may be respectively connected to the limiting ring and the connecting seat 210. In this way, the limiting ring and the connecting seat 210 may be arranged at intervals by the connecting rod 400, so as to form the above-mentioned limiting space between the limiting ring and the connecting seat.

[0035] Furthermore, the baffle can be constructed in any suitable manner. As an exemplary embodiment, the baffle can be constructed as a rectangular plate and can have a third end 1221 and a fourth end 1222 arranged opposite each other along its length. The distance from the third end 1221 to the plug rod 121 can be greater than the distance from the fourth end 1222 to the plug rod 121, so that the third end 1221 can enter or exit the above-mentioned restricted space through the opening 310. In the connection assembly provided in the present disclosure, for ease of operation, as an exemplary embodiment, a handle 123 can be provided on the end of the baffle facing away from the plug rod 121. This makes it easier for workers to operate and rotate the plug connector 120, thereby improving the efficiency of connecting the mine car.

[0036] According to a second aspect of the present disclosure, a mine car assembly is provided, comprising a plurality of mine cars and the above-mentioned connecting assembly, wherein any two adjacent mine cars can be connected via the connecting assembly. Because the mine car assembly has all the above-mentioned beneficial effects, the present disclosure will not elaborate on them here.

[0037] In the mine car group provided by the present disclosure, as an exemplary embodiment, reference is made to Figure 6As shown in , each mine car can be provided with a connecting seat 210 at both ends opposite to each other along the direction of the vehicle body, and the connecting assembly can include a limiter 300, which can be arranged on the top of the connecting seat 210, and the limiter 300 can be used to limit the connector 120 to the connecting seat 210. In this way, it is convenient for the staff to observe from above the connecting seat 210 whether the baffle extends into the above-mentioned limit space. The preferred embodiments of the present disclosure are described in detail above with reference to the accompanying drawings, but the present disclosure is not limited to the specific details of the above-mentioned embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0038] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.
