Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] like Figures 1-7As shown, this utility model provides the following technical solution: a battery replacement auxiliary device for a mining truck, including a trolley 1, an n-shaped plate 2 fixedly connected to the top surface of the trolley 1, a plurality of dovetail grooves 4 symmetrically opened on the bottom surface of the n-shaped plate 2, dovetail blocks 5 slidably fitted inside the dovetail grooves 4, a cavity 3 fixedly connected to the bottom surface of the plurality of dovetail blocks 5 and fitted to the bottom surface of the n-shaped plate 2, a plurality of pairs of second through grooves 16 opened on the bottom surface of the cavity 3, each pair of second through grooves 16 consisting of two second through grooves 16, a clamping plate 6 hinged to the second through groove 16 by a pin, a bearing 11 fixedly embedded in the n-shaped plate 2, a drive mechanism fixedly connected to the inner ring of the bearing 11, the output end of the drive mechanism can drive the clamping plate 6 to rotate slightly and move the clamping plate 6 through the cavity 3.

[0028] Please combine Figure 1 As shown, when the mine car needs battery replacement, place the new battery on top of the trolley 1, then move this device next to the mine car, open the door of the battery mounting bracket on the mine car, remove the plug from the battery, and then disassemble the battery mounting components inside the mounting bracket. Then operate the drive mechanism; the output end of the drive mechanism moves the cavity 3 along the door of the battery mounting bracket and inserts it into the mounting bracket. The cavity 3 moves the clamping plates 6 and inserts them into the mounting bracket. At this time, the multiple clamping plates 6 are on both sides of the battery. Then press the drive mechanism; the output end of the drive mechanism causes the clamping plates 6 on both sides to rotate in opposite directions, clamping and squeezing the battery. Then, position the drive mechanism using the positioning pin. Then operate the drive mechanism again; the output end of the drive mechanism moves the cavity 3, and the cavity 3 moves the clamping plates 6, gradually sliding them out of the mounting bracket. The clamping plates 6 then gradually slide the battery they clamp out of the mounting bracket. When the battery, following the clamping plates 6, gradually comes to the top of the trolley 1, pull out... The positioning pin used for positioning is removed, and the positioning pin removes the positioning of the drive mechanism. The drive mechanism removes the limit on the clamping plate 6. The drive mechanism drives the clamping plate 6 to rotate, causing the clamping plate 6 to separate from the battery surface. The battery slides onto the top surface of the trolley 1 due to gravity. Then, the new battery is pushed forward a certain position so that the battery is between multiple clamping plates 6. Then, the controller is operated to clamp the battery. The drive mechanism is positioned by the positioning pin. The drive mechanism is then operated to indirectly drive the clamping plate 6 holding the battery to move and move the battery into the battery fixing frame. Then, the positioning pin on the drive mechanism is pulled out. The drive mechanism is then operated to make the cavity 3 and the clamping plate 6 slide out of the fixing frame. Then, the battery and plug are installed. After the battery is installed, the battery is fixed and the door on the fixing frame is locked. This realizes the replacement of the mine car battery, reduces manual input, saves time and effort in the disassembly and assembly process, reduces labor costs, and improves the work efficiency of battery replacement.

[0029] The cross-sectional shape of the clamp 6 is serpentine, which increases the contact area between the clamp 6 and the battery surface, thus making it easier for the clamp 6 to clamp the battery.

[0030] The driving mechanism includes a driving component and a pressing component. The output end of the driving component can drive the clamping plate 6 to move through the cavity 3, and the pressing component can drive the clamping plate 6 to rotate slightly.

[0031] Please combine Figure 1 , Figure 2 , Figure 5 , Figure 7 As shown in the embodiment of the drive assembly, the drive assembly includes a cylinder 10, which is fixedly connected to the inner ring of the bearing 11. A handle 7 is slidably provided inside the cylinder 10. A gear 8 is fixedly connected to the bottom end of the handle 7. A rack 9 is meshed on the side end of the gear 8. The rack 9 is fixedly connected to the bottom surface of the cavity 3.

[0032] Please combine Figure 1 As shown, during use, when it is necessary to drive the clamping plate 6 to move, the handle 7 is rotated. The handle 7 drives the cylinder 10 to rotate within the bearing 11. The handle 7 drives the gear 8 to rotate. The gear 8 drives the rack 9 to move. The rack 9 drives the cavity 3 to move. The cavity 3 drives the clamping plate 6 to move, thereby realizing the movement of the battery by the clamping plate 6 and realizing the handling of the battery.

[0033] Please combine Figures 1-5 As shown in the embodiment of the extrusion assembly, the extrusion assembly includes a retaining ring 12, which is fixedly sleeved on the handle 7. The handle 7 and the surface of the cylinder 10 are both provided with positioning holes for pin insertion and limiting. The retaining ring 12 is slidably disposed in the first through groove 13, which is located on the top surface of the cavity 3. A pressure plate 14 is slidably disposed on the top surface of the cavity 3. A through groove 19 is provided on the top surface of the pressure plate 14, which is located directly below the retaining ring 12 and has a width smaller than the diameter of the retaining ring 12. The pressure plate 14 has an n-shaped cross-section. The two vertical plates of the pressure plate 14 have inclined sidewalls facing each other and gradually approach each other from top to bottom. The vertical plates of the pressure plate 14 are slidably disposed in the positioning groove 15, which is located on the top surface of the clamping plate 6. A return spring 18 is fixedly connected between the sidewall of the clamping plate 6 and the inner wall of the cavity 3. Multiple compression springs 17 are fixedly connected between the bottom surface of the pressure plate 14 and the bottom surface of the cavity 3. A rack 9 is disposed below the through groove 19.

[0034] Please combine Figure 1As shown, during use, when the battery needs to be clamped by multiple clamps 6, the operator presses the handle 7. The handle 7 moves the retaining ring 12 downward, which in turn moves the pressure plate 14 downward, compressing the spring 17 and causing it to deform. The vertical plate of the pressure plate 14 pushes the clamp 6 to rotate, and the rotation of the clamp 6 pulls the return spring 18 to deform. Then, the positioning pin passes through the positioning hole on the surface of the handle 7 and the cylinder 10 to limit the handle 7. The handle 7 cannot move, so the retaining ring 12 cannot move. The retaining ring 12 cannot move, so the pressure plate 14 cannot move. The pressure plate 14 cannot move, so the clamp 6 cannot move. 6 cannot move, thus achieving the purpose of clamping the battery. When the handle 7 moves downward, the handle 7 drives the gear 8 to move downward. The gear 8 will always mesh with the rack 9 and will not separate from the rack 9. When it is necessary to release the batteries clamped by multiple clamps 6, the operator pulls out the positioning pin between the handle 7 and the cylinder 10. At this time, the compression spring 17 and the return spring 18 that have been deformed need to restore their deformation. The compression spring 17 pushes the pressure plate 14 to move and reset. The pressure plate 14 drives the retaining ring 12 to move and reset. The return spring 18 drives the clamp 6 to rotate and separate from the battery surface, removing the limit on the battery. At this time, the battery slides down.

[0035] When the handle 7 rotates, it indirectly drives the cavity 3 to slide laterally. The cavity 3 drives the first through groove 13 to slide on the retaining ring 12. The cavity 3 drives the pressure plate 14 to slide laterally. The pressure plate 14 drives the through groove 19 to slide on the handle 7. The through groove 19 is designed to prevent the handle 7 from blocking the sliding of the pressure plate 14.

[0036] The length of the rack 9 is less than the length of the through groove 19. When the pressure plate 14 moves downward, the pressure plate 14 drives the through groove 19 to move through the rack 9, preventing the rack 9 from being too long and restricting the sliding of the pressure plate 14, and expanding the sliding range of the pressure plate 14.

[0037] A rubber air cushion 20 is fixedly connected to the top of the cart 1. The old battery held by the clamp 6 falls onto the rubber air cushion 20 on the cart 1. The rubber air cushion 20 plays a buffering role to reduce the damage to the battery from impacts.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
