Description

Technical Field

[0001] This utility model relates to the field of smart mining equipment technology, specifically to an unmanned electric mining truck anti-sticking carriage. Background Technology

[0002] During the transportation process of unmanned electric mining trucks, the material compaction is promoted by road bumps and its own weight. The material characteristics cause the material to stick to the container and cannot be unloaded smoothly at the dumping yard, resulting in 2 / 3 of the material remaining in the container, which seriously affects the transportation efficiency. The unmanned vehicle dumping program is set up with dumping-lifting the container forward-sudden braking measures, which makes the impact and vibration of the rear container very small. The same method is also very ineffective for manual driving.

[0003] Besides causing severe volume loss, uneven packing also leads to uneven stress on the gas springs, causing damage to the gas springs of the return vehicle over long-term operation. During battery swapping, the uneven load on the packing of electric mining trucks frequently causes the battery swapping robotic arm to jam when the height difference between the left and right ends of the truck exceeds the allowable height difference of the robotic arm at the swapping station, reducing efficiency and creating safety hazards.

[0026] The support plate has two bidirectional threaded rods 22 inside the built-in groove 18. The bidirectional threaded rods 22 are used to convert the rotation of the object into linear motion. The two bidirectional threaded rods 22 are fixedly connected to the abutting ends of the first bevel gear 21 with the second bevel gear 24. The two second bevel gears 24 are meshed with the first bevel gear 21. The direction of force transmission can be changed by the meshing between the two second bevel gears 24 and the first bevel gear 21. The inner wall of the support plate has a limiting plate 23 fixedly connected to the two bidirectional threaded rods 22 with the corresponding positions. The limiting plate 23 is used to fix the bidirectional threaded rods 22 and limit their movement.

The outer walls of the two bidirectional threaded rods 22 are each threaded with a threaded sleeve rod 25. The threaded sleeve rod 25 is used to move the object. The opposite ends of the two threaded sleeve rods 25 are fixedly connected to a T-shaped limiting shaft 26. The T-shaped limiting shaft 26 is used to limit the object and provide a rotation center. The outer walls of the two T-shaped limiting shafts 26 are rotatably sleeved with limiting baffles 27. The first support plate 5 and the second support plate 6 are each provided with a limiting slot 28 at the position corresponding to the limiting baffle 27. The second support plate 6 can be fixed by the limiting baffle 27 and the limiting slot 28.

[0028] Working principle: When installing the first carriage floor plate 8, second carriage floor plate 9, third carriage floor plate 10, and fourth carriage floor plate 11 with the cargo box connecting floor plate 1, firstly, the second carriage floor plate 9 and the fourth carriage floor plate 11 are inserted into the two second slots 15 of the first carriage floor plate 8 and the third carriage floor plate 10 using two second insert plates 16, and fixed with countersunk bolts. Then, the third carriage floor plate 10 and the fourth carriage floor plate 11 are inserted into the two first slots 13 of the first carriage floor plate 8 and the second carriage floor plate 9 using two first insert plates 14, and fixed with countersunk bolts. After the first carriage floor plate 8, second carriage floor plate 9, third carriage floor plate 10, and fourth carriage floor plate 11 are assembled, they are then fixed to the cargo box connecting floor plate 1 with other countersunk bolts. The second support plate 6... The same principle applies to the fixing and installation of the plate components. After fixing, rotate the two second support plates 6 between the two first support plates 5 and keep them perpendicular to the bottom plate 1 of the cargo box. At this time, turn the transmission block 17 with a wrench. The rotation of the transmission block 17 synchronously drives the transmission shaft 20 to rotate. The transmission shaft 20 synchronously drives the two bidirectional threaded rods 22 to rotate through the meshing of the first bevel gear 21 and the two second bevel gears 24. The two bidirectional threaded rods 22 synchronously drive the two threaded sleeves 25 to slide relative to each other along the inner wall of the built-in groove 18 of the support plate. The two threaded sleeves 25 synchronously drive the two limiting baffles 27 to move relative to each other through the T-shaped limiting shaft 26. When the two limiting baffles 27 move, adjust them to the position corresponding to the limiting slot 28. The two limiting baffles 27 can then slide into the inner wall of the limiting slot 28, thereby fixing the second support plate 6.
