It is mainly used for material transportation operations in mining environments and is environmentally friendly, efficient and intelligent. This type of vehicle plays an important role in mining transportation, not only improving operating efficiency, but also improving the working environment in mining areas. The technical basis of unmanned wide-body trams for mining lies in their electrification and intelligent characteristics. Electrification is an important development direction in the field of off-road wide-body dump trucks. The transition from fuel vehicles to electric vehicles not only conforms to the trend of energy conservation and emission reduction, but also reduces operating costs.

It can be used when the battery is not replaced to improve convenience.

[0040] When the battery box 5 is located in the placement box 3, when the first gear 10 is driven to rotate, the roller 11 will also rotate, resulting in relative friction between the roller 11 and the bottom wall of the placement box 3 causing wear. In order to solve this problem, the following embodiment is provided.

[0041] See also Figure 5 , Figure 6 and Figures 9 to 12In the embodiment of the present invention, wheel grooves 302 are provided at the four corners of the bottom wall of the placement box 3. When the battery box 5 is located inside the placement box 3, the four rollers 11 at the bottom of the battery box 5 are respectively located in the four wheel grooves 302, and pads 28 are slidably installed inside the wheel grooves 302. An adjustment mechanism for driving the pads 28 to move is provided inside the bottom wall of the placement box 3.

[0042] In this embodiment, preferably, the adjustment mechanism includes a slide bar 29, a rack 31 and a third gear 32.

[0043] In this embodiment, preferably, two elastic connection components 18 are installed inside the battery box 5, and the elastic connection component 18 includes a connecting tube 181 and a connecting column 183. The top end of the connecting tube 181 is fixedly connected to the battery box 5, and the top end of the connecting column 183 extends into the interior of the connecting tube 181. A slider 182 is fixedly installed on the top end of the connecting column 183. The slider 182 slides with the connecting tube 181. The top end of the slider 182 is fixedly connected with a spring 185. The top end of the spring 185 is fixedly connected to the top wall of the connecting tube 181. A limiting ring 184 is fixedly installed inside the connecting tube 181, and a support ring 19 is fixedly installed on the bottom end of the connecting column 183. The second rotating shaft 15 passes through the two support rings 19, and the second rotating shaft 15 is rotatably connected to the support ring 19. When the battery box 5 is placed on the ground, under the action of the weight of the battery box 5 itself, the spring 185 is compressed, and the slider 182 contacts the limiting ring 184.

[0044] When the side sealing plate 4 is opened, the cushion block 28 is located in the middle of the inner cavity of the wheel groove 302. When the roller 11 moves into the wheel groove 302, the roller 11 presses on the cushion block 28. At this time, there is a certain gap between the bottom wall of the battery box 5 and the bottom wall of the placement box 3, so that the battery box 5 can be easily moved. Then the side sealing plate 4 is closed. When the side sealing plate 4 rotates, it drives the connecting shaft 30 to rotate. When the connecting shaft 30 rotates, it drives the third gear 32 to rotate, thereby driving the rack 31 to move. When the rack 31 moves, it drives the cushion block 28 to move through the sliding rod 29, so that the cushion block 28 is separated from the roller 11, so that the roller 11 moves downward. At this time, the battery box 5 moves downward until the bottom wall contacts the bottom wall of the placement box 3, so that the battery box 5 It will not shake, and then under the elastic action of the spring 185, the slider 182 pushes the limit ring 184 downward through the connecting column 183, thereby driving the second rotating shaft 15 to move downward until the roller 11 contacts the bottom wall of the wheel groove 302. Due to the downward movement of the support ring 19, the second rotating shaft 15 will drive the second bevel gear 17 to move downward, so that the first bevel gear 16 is separated from the second bevel gear 17, so that when the motor 12 drives the second gear 14 to rotate through the first rotating shaft 13, the roller 11 will not rotate, so that when the motor 12 drives the slide 8 of the lifting mechanism to rise and fall, the roller 11 will not rotate, thereby avoiding the wear caused by the mutual friction between the roller 11 and the bottom wall of the placement box 3.

[0045] See also Figure 3 and Figure 4 In the embodiment of the present invention, two telescopic rods 23 are installed on one side of the battery box 5, and a grip rod 24 is installed on the top of the two telescopic rods 23. Two control switches 25 are arranged on the grip rod 24. The battery box 5 can be conveniently moved by holding the grip rod 24. The two control switches 25 respectively control the forward and reverse rotation of the motor 12, so that the roller 11 drives the battery box 5 forward or backward. Two locking buckles 26 are fixedly installed on one side of the grip rod 24. When the side sealing plate 4 is closed and the telescopic rod 23 is retracted, the two locking buckles 26 lock the side sealing plate 4, thereby locking the side sealing plate 4 to prevent it from rotating. The side sealing plate 4 can be conveniently locked, which improves the convenience of operation.

[0046] It should be noted that when the first power interface 20 and the second power interface 21 are connected, the motor 12 can also be controlled by the electric vehicle body 1 to drive the placement table to rise and fall. It can be controlled by PLC, single-chip microcomputer, etc. The specific electrical connection and control methods are all existing technologies and will not be described in detail here.

[0047] Working principle: when the battery needs to be replaced, the motor 12 is turned on, and the motor 12 drives the first rotating shaft 13 to rotate. When the first rotating shaft 13 rotates, the first gear 10 is driven to rotate through the second gear 14, thereby driving the rotating cylinder 9 to rotate. The rotating cylinder 9 rotates and moves downward relative to the screw 7, thereby driving the placement box 3 to move downward through the slide seat 8, so that the placement box 3 contacts the ground, and then the telescopic rod 23 is pulled out, so that the locking buckle 26 contacts the lock of the side sealing plate 4, and then the side sealing plate 4 is opened. When the side sealing plate 4 is opened, the rotation of the connecting shaft 30 moves the cushion block 28 to the bottom of the roller 11 through the adjustment mechanism, so that the cushion block 28 pushes the roller 11 to move upward, so that the second rotating shaft 15 moves upward, so that the first bevel gear 16 is meshed with the second bevel gear 17, so that the motor 12 can drive the roller 11 to rotate, and then the battery box 5 can be moved out;

[0048] Then the fully charged battery box 5 is moved into the placement box 3 by the roller 11. When the roller 11 moves into the wheel groove 302, the roller 11 presses on the cushion block 28. At this time, there is a certain gap between the bottom wall of the battery box 5 and the bottom wall of the placement box 3, so that the battery box 5 can be easily moved. Then the side sealing plate 4 is closed. When the side sealing plate 4 rotates, it drives the connecting shaft 30 to rotate. When the connecting shaft 30 rotates, it drives the third gear 32 to rotate, thereby driving the rack 31 to move. When the rack 31 moves, it drives the cushion block 28 to move through the slide bar 29, so that the cushion block 28 is separated from the roller 11, so that the roller 11 moves downward. At this time, the battery box 5 moves downward to the bottom wall and the placement box 3. The bottom wall of the wheel groove 302 is contacted with the slider 182, so that the battery box 5 does not shake. Then, under the elastic action of the spring 185, the slider 182 pushes the limit ring 184 downward through the connecting column 183, thereby driving the second rotating shaft 15 to move downward until the roller 11 contacts the bottom wall of the wheel groove 302. Due to the downward movement of the support ring 19, the second bevel gear 17 is driven downward through the second rotating shaft 15, so that the first bevel gear 16 is separated from the second bevel gear 17, so that when the motor 12 drives the second gear 14 to rotate through the first rotating shaft 13, the roller 11 will not rotate, so that when the motor 12 drives the slide seat 8 of the lifting mechanism to rise and fall, the roller 11 will not rotate;

[0049] Then the motor 12 can be controlled to drive the first rotating shaft 13 to rotate. When the first rotating shaft 13 rotates, the first gear 10 is driven to rotate through the second gear 14, thereby driving the rotating cylinder 9 to rotate. The rotating cylinder 9 rotates and moves upward relative to the screw 7, thereby driving the placement box 3 to move upward through the slide 8, so that the placement box 3 moves into the power supply box 2, thereby completing the power replacement.

[0050] The above description is only a preferred embodiment of the present invention, so all equivalent changes or modifications made according to the structure, characteristics and principles described in the scope of the patent application of the present invention are included in the scope of the patent application of the present invention.
