DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0021] Reference Figures 1-4 The utility model relates to a heavy truck quick battery replacement station, including support frame 1, support frame 1 is steel structure's scaffold, adopts angle steel or square steel to build, fixedly connected with slide rail 2 in support frame 1, and the slide rail 2 is provided with row and hangs 3, and row and hangs 3 with slide rail 2 are matched equipment, is hoisting turnover commonly used equipment in prior art, fixedly connected with battery rack assembly on row and hangs 3,

[0022] The battery rack assembly includes a frame 4, the lower end inner wall of the frame 4 is embedded with a ball bearing, and two inner frames 5 are slidingly connected in the frame 4. In the initial state, the two inner frames 5 are diagonally arranged. The lower surface of the inner frame 5 is rotatably connected with a roller shaft 6. The upper end of the frame 4 is fixedly connected with a drive motor 7. The output end of the drive motor 7 is fixedly connected with a rotating rod 8, and the rotating rod 8 is slidingly connected with the inner frame 5. The inner wall of the inner frame 5 is rotatably connected with a limiting rod 9 through a spring shaft. The side wall of the limiting rod 9 is fixedly connected with a crossbar 10. The crossbar 10 is arranged in abutment with the roller shaft 6. The frame 4 is provided with a push block 11 for rotating the limiting rod 9.

[0023] In this design, two inner frames 5 are provided in the frame 4. When replacing the battery, the user first places the fully charged battery into the inner frame 5, then controls the drive motor 7 to operate, uses the drive motor 7 to drive the rotating rod 8 to move, causing the inner frame 5 to displace slightly. At this time, the push block 11 is separated from the limiting rod 9, causing the crossbar 10 to abut against the roller shaft 6, so that the roller shaft 6 cannot rotate. Then, the user controls the row and hangs 3 to move the frame 4 to the vicinity of the heavy truck, and during the operation of the row and hangs 3, since the roller shaft 6 cannot rotate, it can ensure that the fully charged battery will not slide in the inner frame 5. Subsequently, the user controls the height of the frame 4 using the row and hangs 3, and controls the drive motor 7 to rotate, causing the idle inner frame 5 to align with the battery compartment of the heavy truck, while the push block 11 abuts against the limiting rod 9, causing the crossbar 10 to separate from the roller shaft 6. At this time, the user can easily push the discharged battery into the idle inner frame 5. Finally, the user controls the drive motor 7 to rotate again, moves the inner frame 5 containing the fully charged battery to a position close to the battery compartment of the heavy truck, and pushes the fully charged battery into the battery compartment. This method not only has high automation, but also saves labor, greatly improves the battery replacement speed, and improves the utilization rate of heavy trucks and the system operation efficiency.

[0024] Further, a plurality of anti-slip protrusions 12 are fixedly connected to the side plate of the roller shaft 6 near the crossbar 10. A plurality of limiting grooves are formed in the crossbar 10.

[0025] In the design, the frictional force requirement of the horizontal rod 10 for limiting the roller shaft 6 is reduced by setting the protection convex point matched with the limiting groove, the rotation limiting effect of the roller shaft 6 is improved, the stability during the operation of the travelling crane 3 is improved, and the battery is prevented from sliding in the inner frame 5 during the operation of the travelling crane 3.

[0026] Further, the lower end inner wall of the frame body 4 is fixedly connected with a cross-shaped frame 13, and the inner frame 5 is slidably connected with the cross-shaped frame 13.

[0027] The cross-shaped frame 13 is set to better limit and support the inner frame 5, and ensure the stable movement of the inner frame 5 in the frame body 4.

[0028] Further, the upper and lower ends of the limiting rod 9 are provided with extension blocks, and the extension blocks are arranged in abutment with the push block 11.

[0029] The extension blocks are set to cooperate with the push block 11, ensure that the push block 11 can effectively drive the limiting rod 9 to rotate, improve the allowable error amount, and prolong the rotation limiting time of the roller shaft 6.

[0030] Further, the support frame 1 is provided with a storage bin 14, and the storage bin 14 is provided with a charging connector.

[0031] In the design, the storage bin is set to charge the battery in need nearby, improve the battery circulation efficiency, and utilize the ventilation opening 15 and the cooling fan 16 to cool the battery during the charging process, and reduce the risk of overheating and fire during the battery charging process.

[0032] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
