Unenclosed carriage roof

Abstract

The invention relates to an unenclosed carriage roof. The roof comprises an arc cover, a support surface and locking devices, wherein the arc cover and the support surface are made of a glass fiber reinforced plastic material; the arc cover is contacted with the top of four sides of the unenclosed carriage through the support surface; screw holes are arranged on the support surface, and a plurality of the locking devices are distributed on the support surface through bolts; and the locking device comprises a base body, a hook base, a hook, a locking hook base, a locking hook and a connecting rod. After the roof is positioned on the roof, the hook slides downwards under the action of dead weight, the locking hook base driven by the connecting rod is overturned downwards, and the locking hook is hooked on a lateral beam of a vehicle body; and when the roof is opened, the hook slides upwards due to the upper traction of hoisting equipment, the locking base driven by the connecting rod isoverturned upwards, so that the lock-shaped locking hook is separated from the upper beam of the vehicle body to realize automatic unlocking. The unenclosed carriage roof has a simple structure, reliable locking and flexible starting, rain water is effectively prevented from intruding to cause goods damage, and the environment pollution of dusty and dirty goods can be avoided.

Description

technical field [0001] The invention relates to the fields of railway and road freight transport, and is especially suitable for open railway carriages with a top cover. Background technique [0002] Open carriages refer to truck carriages that have end walls, side walls, floors and no roofs, and are open upwards. They are mainly used to transport bulk goods such as coal, ore, mining construction materials, wood, and steel, and can also be used to transport light weight. mechanical 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 gen...
