[0002] The existing high-end transformers with high voltage level and large capacity need to be transported by air cushion vehicles when entering the furnace for drying. When the air cushion vehicles are transporting the transformer bodies into the furnace, the bottom of the drying furnace is smooth and the air cushion vehicles have no brake device, which causes the air cushion vehicles to slide after stopping, making the transformer body inaccurately placed. At the same time, due to the small space of the drying furnace, the air cushion vehicles cannot brake when they stop, and they are also prone to collide with the furnace wall, causing equipment and product property losses. Therefore, the art urgently needs to design a safe brake device for air cushion vehicles entering and exiting the drying furnace. Summary of the invention
