[0023] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0024] The following describes the carriage 100 of the mining vehicle 1000 according to an embodiment of the present invention with reference to the accompanying drawings. Figure 1-Figure 7 As shown, the carriage 100 of a mining car 1000 according to an embodiment of the present invention includes a carriage 1 and a bottom plate 2. The carriage 1 has an ore chamber 11 for accommodating ore, with the lower end of the ore chamber 11 open. The carriage 1 includes a front end plate 12 and a rear end plate 13 that are opposite to each other in the longitudinal direction thereof.

[0025] The bottom plate 2 includes a plate body 21, which is rotatably mounted on the body 1 between a closed position, which seals the lower end of the ore chamber 11, and a ore-unloading position, which opens the lower end of the ore chamber 11. The rotation axis of the plate body 21 extends along the length of the body 1. In other words, the mine car 1000 including the car body 100 is a bottom-side unloading mine car. The plate body 21 is positioned between the lower end 121 of the front plate 12 and the lower end 131 of the rear plate 13 along the length of the body 1. The lower end 121 of the front plate 12 opposes the plate body 21 along the length of the body 1, and the lower end 121 of the front plate 12 cooperates with the plate body 21. The lower end 131 of the rear plate 13 opposes the plate body 21 along the length of the body 1, and the lower end 131 of the rear plate 13 cooperates with the plate body 21.

[0026] When the mine car 1000 moves forward, the force on the coupler 200 is first transmitted to the car body 1, then transmitted to the plate body 21 (bottom plate 2) through the lower end portion 131 of the rear end plate 13 of the car body 1, and finally transmitted to the wheelset to drive the mine car 1000 forward. When the mine car 1000 moves backward, the force on the coupler 200 is first transmitted to the car body 1, then transmitted to the plate body 21 (bottom plate 2) through the lower end portion 121 of the front end plate 12 of the car body 1, and finally transmitted to the wheelset to drive the mine car 1000 forward.

[0027] The lower ends of the front and rear panels of existing carriages do not align with and mate with the floor panel along the length of the carriage. Consequently, the force applied to the coupler 200, after being transmitted to the carriage, can only be transferred to the floor panel via the pin (the floor panel is rotatably mounted to the carriage via this pin). This can lead to severe deformation of the existing carriage after a period of use.

[0028] According to the embodiment of the utility model, the car body 100 makes the lower end portion 121 of the front end plate 12 and the lower end portion 131 of the rear end plate 13 opposite to and matched with the plate body 21 in the length direction of the car body 1. Therefore, when the mine car 1000 moves, the lower end portion 121 of the front end plate 12 and the lower end portion 131 of the rear end plate 13 can be used to transmit the force on the coupler 200 to the plate body 21 and the wheelset, thereby driving the mine car 1000 to move, so as to avoid deformation of the car body 1.

[0029] The carriage 100 according to the embodiment of the present invention has the advantages that the carriage body 1 is not easily deformed and has a long service life.

[0030] like Figure 1-Figure 7 As shown, the carriage 100 of the mining car 1000 includes a carriage 1 and a floor 2. The carriage 1 includes a front end plate 12 and a rear end plate 13 that oppose each other in the longitudinal direction thereof. The carriage 1 also includes a first side plate 14 and a second side plate 15 that oppose each other in the width direction thereof. The front end plate 12, the rear end plate 13, the first side plate 14, and the second side plate 15 define an ore chamber 11 for accommodating ore. The lower end of the ore chamber 11 is open.

[0031] The plate body 21 of the bottom plate 2 is located between the lower end portion 121 of the front end plate 12 and the lower end portion 131 of the rear end plate 13 in the longitudinal direction of the body 1. The lower end portion 121 of the front end plate 12 and the plate body 21 are opposite and matched in the longitudinal direction of the body 1, and the lower end portion 131 of the rear end plate 13 and the plate body 21 are opposite and matched in the longitudinal direction of the body 1.

[0032] like Figure 5 As shown, a portion of the lower end of the front plate 12 is located below the plate body 21, and a portion of the lower end of the rear plate 13 is located below the plate body 21. In other words, the front plate 12 extends downward from the plate body 21, and the rear plate 13 extends downward from the plate body 21. This allows the force on the coupler 200 to be more effectively and stably transmitted to the plate body 21 and the wheelset, thereby further preventing deformation of the car body 1 and extending the service life of the car body 1.

[0033] like Figure 1 and Figure 4As shown, the plate 21 has a front edge 211 and a rear edge 212 that are opposite to each other in the longitudinal direction of the body 1. That is, the front edge 211 and the rear edge 212 are opposite to each other in the longitudinal direction of the plate 21. The longitudinal direction of the plate 21 is consistent with the longitudinal direction of the body 1, and the width direction of the plate 21 is consistent with the width direction of the body 1. The longitudinal direction of the body 1 is as shown in FIG. Figure 1 As shown by the arrow C in FIG, the width direction of the compartment 1 is as follows Figure 3 As shown by arrow D in FIG.

[0034] The base plate 2 further includes a front stopper 22 and a rear stopper 23. The front stopper 22 is disposed at the front edge 211 and extends upward from the front edge 211. The rear stopper 23 is disposed at the rear edge 212 and extends upward from the rear edge 212. In other words, the lower end 223 of the front stopper 22 is disposed on the front edge 211 of the plate body 21, and the lower end 233 of the rear stopper 23 is disposed on the rear edge 212 of the plate body 21.

[0035] Therefore, when unloading ore, the front baffle plate 22 and the rear baffle plate 23 can be used to block the ore and prevent it from falling through the gap between the plate body 21 and the front plate 12 and the gap between the plate body 21 and the rear plate 13. Ore falling through the gap between the plate body 21 and the front plate 12 and the gap between the plate body 21 and the rear plate 13 may hit the curved rail and cause damage to the curved rail.

[0036] Optionally, when the plate body 21 is in the ore unloading position, a portion of the front baffle plate 22 is opposed to a portion of the front end plate 12 in the longitudinal direction of the body 1, and a portion of the rear baffle plate 23 is opposed to a portion of the rear end plate 13 in the longitudinal direction of the body 1. In other words, a portion of the front baffle plate 22 overlaps with a portion of the front end plate 12, and a portion of the rear baffle plate 23 overlaps with a portion of the rear end plate 13. In other words, a portion of the front baffle plate 22 overlaps with a portion of the front end plate 12, and a portion of the rear baffle plate 23 overlaps with a portion of the rear end plate 13. This further prevents ore from falling through the gaps between the plate body 21 and the front end plate 12, and between the plate body 21 and the rear end plate 13.

[0037] like Figure 5 As shown, the front end plate 12 has a front accommodating cavity 122 with an open lower end, and the rear end plate 13 has a rear accommodating cavity 132 with an open lower end. The front baffle plate 22 is movably engaged within the front accommodating cavity 122, and the rear baffle plate 23 is movably engaged within the rear accommodating cavity 132. Specifically, when the plate body 21 is in the closed position, at least a portion of the front end plate 12 is located within the front accommodating cavity 122, and at least a portion of the rear end plate 13 is located within the rear accommodating cavity 132. When the plate body 21 is in the unloading position, at least a portion of the front end plate 12 extends out of the front accommodating cavity 122, and at least a portion of the rear end plate 13 extends out of the rear accommodating cavity 132.

[0038] In this way, not only can the front end plate 12 be used to protect the front baffle plate 22, and the rear end plate 13 can be used to protect the rear baffle plate 23, so as to reduce the structural strength and weight of the front baffle plate 22 and the rear baffle plate 23, but also the friction between the front baffle plate 22 and the rear baffle plate 23 and the ore can be greatly reduced, making it easier for the plate body 21 to move from the closed position to the unloading position.

[0039] like Figure 4 As shown, the front baffle 22 has a first edge 221 and a second edge 222 that are opposite each other in the width direction of the plate body 21, each of which is arc-shaped. The rear baffle 23 has a third edge 231 and a fourth edge 232 that are opposite each other in the width direction of the plate body 21, each of which is arc-shaped. As a result, when the front baffle 22 and the rear baffle 23 move, the front baffle 22 can be prevented from interfering with the wall surface of the front storage chamber 122, and the rear baffle 23 can be prevented from interfering with the wall surface of the rear storage chamber 132, thereby making the structure of the body 1 more reasonable.

[0040] like Figure 1-Figure 3 As shown, the carriage 100 further includes a first upper beam 31, a second upper beam 32, a first merging beam 4, a second merging beam 5, a first reinforcing rib 61, and a second reinforcing rib 62. The first upper beam 31 is provided on the upper portion of the first side panel 14, and the second upper beam 32 is provided on the upper portion of the second side panel 15. The first merging beam 4 is provided on the lower portion of the first side panel 14, and the second merging beam 5 is provided on the lower portion of the second side panel 15. The first reinforcing rib 61 is provided on the first side panel 14, with the upper end 611 of the first reinforcing rib 61 connected to the first upper beam 31, and the lower end 612 of the first reinforcing rib 61 connected to the first merging beam 4. The second reinforcing rib 62 is provided on the second side panel 15, with the upper end 621 of the second reinforcing rib 62 connected to the second upper beam 32, and the lower end 622 of the second reinforcing rib 62 connected to the second merging beam 5.

[0041] Compared to existing carriages, the carriage 100 of the present application combines the lower beam and the middle beam to form the first combined beam 4 and the second combined beam 5. In other words, the carriage 100 of the present application eliminates the middle beam, and the first combined beam 4 and the second combined beam 5 are arranged at the lower portion of the carriage body 1, with the first combined beam 4 and the second combined beam 5 being equivalent to the lower beam. At the same time, the lengths of the first and second reinforcing ribs 61 and 62 are extended, so that the first reinforcing rib 61 is connected to the first upper beam 31 and the first combined beam 4, and the second reinforcing rib 62 is connected to the second upper beam 32 and the second combined beam 5. This not only simplifies the structure of the carriage 100, but also reduces the travel resistance of the carriage 100.

[0042] Optionally, the carriage 100 further includes a third upper beam 33 and a fourth upper beam 34. The third upper beam 33 is provided on the upper portion of the front end plate 12, and the fourth upper beam 34 is provided on the upper portion of the rear end plate 13. The first upper beam 31, the third upper beam 33, the second upper beam 32, and the fourth upper beam 34 are sequentially connected to form an upper ring beam.

[0043] like Figure 1-Figure 3 、 Figure 6 and Figure 7 As shown, the first merging beam 4 is provided on the outer side surface 141 of the first side plate 14, and the second merging beam 5 is provided on the outer side surface 151 of the second side plate 15. This can make the structure of the carriage 100 more reasonable.

[0044] Optionally, the height of the first merging beam 4 decreases in the direction away from the first side plate 14 in the width direction of the car body 1. The height of the second merging beam 5 decreases in the direction away from the second side plate 15 in the width direction of the car body 1. The height of the first merging beam 4 (the second merging beam 5) is the dimension of the first merging beam 4 (the second merging beam 5) in the up-down direction. Figure 3 As shown by the arrow E in FIG. , the weight of the first merging beam 4 and the second merging beam 5 can be reduced while ensuring the structural strength of the car body 1 , thereby reducing the weight of the car body 100 .

[0045] For example, the width direction of the vehicle body 1 is consistent with the left-right direction, the first side panel 14 is located on the left side of the second side panel 15, the height of the first merging beam 4 decreases from right to left, and the height of the second merging beam 5 decreases from left to right. Figure 3 As shown by arrow F in FIG.

[0046] like Figure 1-Figure 3 as well as Figure 6 As shown, the upper surface 41 of the first merging beam 4 has a first side edge 411 (e.g., the right side edge) and a second side edge 412 (e.g., the left side edge) that are opposite to each other in the width direction of the vehicle body 1. The first side edge 411 is connected to the outer side surface 141 of the first side panel 14. The upper surface 41 of the first merging beam 4 is arranged at an angle, and the second side edge 412 is located below the first side edge 411.

[0047] The lower surface 42 of the first merging beam 4 has a third side edge 421 (e.g., the right side edge) and a fourth side edge 422 (e.g., the left side edge) that are opposite each other in the width direction of the vehicle body 1. The third side edge 421 is connected to the outer side surface 141 of the first side panel 14. The lower surface 42 of the first merging beam 4 is inclined, with the fourth side edge 422 located above the third side edge 421. This makes the structure of the first merging beam 4 more rational.

[0048] like Figure 1-Figure 3 as well as Figure 7As shown, the upper surface 51 of the second merging beam 5 has a fifth side edge 511 (e.g., the left side edge) and a sixth side edge 512 (e.g., the right side edge) that are opposite to each other in the width direction of the vehicle body 1. The fifth side edge 511 is connected to the outer side surface 151 of the second side panel 15. The upper surface 51 of the second merging beam 5 is arranged at an angle, and the sixth side edge 512 is located below the fifth side edge 511.

[0049] The lower surface 52 of the second merging beam 5 has a seventh side edge 521 (e.g., the left side edge) and an eighth side edge 522 (e.g., the right side edge) that oppose each other in the width direction of the vehicle body 1. The seventh side edge 521 is connected to the outer side surface 151 of the second side panel 15. The lower surface 52 of the second merging beam 5 is inclined, with the eighth side edge 522 located above the seventh side edge 521. This makes the structure of the second merging beam 5 more rational.

[0050] Alternatively, the cross-section of the first merging beam 4 can be an isosceles trapezoid, and the cross-section of the second merging beam 5 can be an isosceles trapezoid. This can make the structures of the first merging beam 4 and the second merging beam 5 more reasonable. The cross-sections of the first merging beam 4 and the second merging beam 5 are both perpendicular to the length direction of the car body 1.

[0051] When the mining car 1000 unloads ore at the unloading station, the lower surface 42 of the first merging beam 4 and the lower surface 52 of the second merging beam 5 are supported on the rollers of the unloading station.

[0052] like Figure 1 and Figure 2 As shown, there are multiple first reinforcing ribs 61, which are spaced apart along the length direction of the body 1, and multiple second reinforcing ribs 62, which are spaced apart along the length direction of the body 1. This can further improve the structural strength of the body 1 and the carriage 100.

[0053] Optionally, the size of the first reinforcing rib 61 decreases from bottom to top in the longitudinal direction of the body 1, and the size of the second reinforcing rib 62 decreases from bottom to top in the longitudinal direction of the body 1. This can reduce the weight of the first reinforcing rib 61 and the second reinforcing rib 62 while ensuring the structural strength of the body 1, thereby reducing the weight of the car body 100.

[0054] The mining car 1000 of the present invention comprises a carriage 100 and a coupler 200 . The coupler 200 is arranged on the body 1 of the carriage 100 .

[0055] The mining car 1000 according to the embodiment of the present invention has the advantages that the car body 1 is not easily deformed and has a long service life.
