[0002] Lithium battery monorail crane is an advanced transportation equipment. It mainly uses lithium battery as power source to drive the crane on the monorail. Lithium battery has high energy density and long endurance, providing stable and reliable power for the crane. The crane runs along the monorail and can move flexibly in a narrow space to achieve efficient transportation of materials. Lithium battery monorail crane is widely used in mines, factories, warehouses and other places. In mines, it can be used to transport ore, equipment and materials to improve mine production efficiency. In factories and warehouses, it can realize rapid handling and loading and unloading of materials, saving manpower and time costs. Most of the existing lithium battery monorail cranes are used for transportation of coal mines in mines.

[0003] In order to facilitate the replacement and maintenance of lithium batteries, monorail cranes usually install lithium batteries externally on the frame.

The lithium battery is wrapped and covered by the square casing 301 for safety protection, and the cooling device 4 sprays cold air into the square casing 301 to the square casing When the interior of 301 is filled with cold air, the cold air will enter the exhaust circular hole 307, pass through the dust filter circular plate 309 and push the fan-shaped baffle 308 to bend slightly outward to take away the heat and discharge it to the outside. The exhaust circular hole 307 is blocked by arranging four fan-shaped baffles 308 at the exhaust circular hole 307, and a dust filter circular plate 309 is arranged on one side of the fan-shaped baffle 308 in the exhaust circular hole 307 close to the inner side of the square casing 301 to block a small amount of coal powder and dust in the cold air. The top circular shell 408 is evacuated by the high-pressure air pump 401. At this time, the inner sliding circular plate 411 is continuously moved downward by the suction force and compresses the extension spring 410 at the bottom. Until the inner sliding circular plate 411 moves down to the area of ​​the arc-shaped inner groove 413, the top area of ​​the inner sliding circular plate 411 and the bottom area The domains are connected, at this time, the high-pressure air pump 401 draws external air into the top circular shell 408 through the dust filter circular hole 409 and draws it into the annular concave shell 402 at the bottom. By opening a plurality of dust filter circular holes 409 on the top of the top circular shell 408, it is convenient to block coal powder and dust. When the annular concave shell 402 is filled with gas, it will enter the circular empty shell 403 through the ventilation circular hole 404 and contact the annular condenser 405 to be quickly cooled down. The gas is quickly cooled by the annular condenser 405 and blown to the lithium battery to cool it down. The gas cooled by the annular condenser 405 continues to flow downward and passes through the ventilation circular hole 404 at the bottom and is blown to the surface of the lithium battery inside the square shell 301 to quickly cool the lithium battery. By aligning the plurality of ventilation circular holes 404 with the circular empty shell The annular condenser 405 in 403 allows the gas entering the circular empty shell 403 to directly contact the annular condenser 405. When the high-pressure air pump 401 is turned off and the lithium battery is not cooled, the extension spring 410 pushes the inner smooth circular plate 411 upward through the extension force. When the inner smooth circular plate 411 moves upward, it drives the small thorn block 412 on the top to move together. When the small thorn block 412 moves upward, it penetrates into the dust filter circular hole 409 and clears the inside of the dust filter circular hole 409. The motor 502 is started to drive the threaded long rod 501 to rotate. When the threaded long rod 501 rotates, it drives the concave scraper 503 on the inner side of the square casing 301 that is threadedly matched with it to move toward the long connecting rod 505. When the concave scraper 503 moves, it scrapes and cleans the inner surface of the square casing 301 and the outer surface of the lithium battery.When the concave scraper 503 moves, it drives the long connecting rod 505 on one side to move together and push the corrugated ring piece 504 to make it corrugated and shrink. The corrugated ring piece 504 connected to the concave scraper 503 is sleeved on the outer surface of the threaded long rod 501 to wrap and cover it. When the concave scraper 503 moves to contact the block 304 on the inner side of the frame door 303, the cleaned coal powder and dust are discharged to the outside of the square casing 301. The motor 502 reverses the threaded long rod 501 to drive the concave scraper 503 to the inner side of the square casing 301. When the concave scraper 503 moves back, the concave blocking plate 506 at one end is driven to move back together through the long connecting rod 505. When the concave blocking plate 506 moves back to the inner side of the frame door 303 and is aligned with the block 304 as the long connecting rod 505, it blocks the insertion port of the square casing 301. When the concave scraper 503 moves back, the short connecting rod 507 on one side drives the bottom scraper 508 to move back together. When the bottom scraper 508 moves back, it scrapes and cleans the area on the bottom of the inner wall of the square casing 301 on the side of the concave scraper 503 away from the long connecting rod 505.
