The open carriage refers to a truck with end walls, side walls, floors and no roof, which is opened upwards. It is mainly used for transporting bulk goods such as coal, ore, mining materials, wood, steel, etc., and can also be used to transport light weight goods. Equipment. If the goods being shipped are covered with tarpaulins or other canopies, they can replace boxcars to carry goods that are afraid of rain. Therefore open carriages have great versatility, and are the largest in number in freight cars. At present, there are about 300,000 open carriages in the whole railway, accounting for more than 50% of the total number of freight cars. If the transported goods are exposed to rain, it will cause rust, deterioration, etc., and the bulk goods will generate dust during transportation, which will have an impact on the environment. The usual method is to use tarpaulins to cover them. However, covering the tarpaulins takes time and prevents rain. Incomplete, difficult to keep, easy to lose, often transported goods are still subject to water damage, and bulk goods increase the difficulty of unloading due to increased humidity. Therefore, there have been specially designed top covers for open compartments both at home and abroad, such as the Chinese patent "railway transport open compartment special top cover" etc. whose publication number is CN2441704. However, when the existing top cover is installed on the open compartment, the fixing method of the top cover is cumbersome, poor in reliability, and inconvenient to open, which limits the use of the top cover in the open compartment and restricts the benefit of the open compartment.
