Unenclosed carriage roof

Abstract

The present invention relates to an open wagon cover comprising an arched hood, a support face, and a locking apparatus. The arched hood and the support face are made of a fiber reinforced plastic material, and via the supporting face, the arched hood is in contact with the top face of the four surrounding sides of an open wagon. The support face has bolt holes arranged thereon; a plurality of locking apparatus are arranged distributedly on the support face via the bolt holes. The locking apparatus comprises a block body, a lifting hook block, a lifting hook, a locking hook block, a locking hook, and a connecting rod. When the cover is placed on top of the wagon, the lifting hook slides downward under the effect of gravity, and drives via the connecting rod the locking hook block to turn downward, and the locking hook hooks onto the side beam of the wagon body. When the cover is opened, the lifting hook slides upward under the upward traction effect of a lifting apparatus, and drives via the connecting rod the locking hook block to turn upward, and the locking hook detaches from the side beam of the wagon body, thereby allowing automatic unlocking. The present invention has a simple structure, a reliable locking and quick unlocking feature, and is effective in the prevention of damage to cargo due to rain water intrusion, and of environmental pollution due to flying dust from the cargo.

Description

technical field [0001] The invention relates to the field of railway and road freight transportation, and is especially suitable for a railway open carriage with a top cover. Background technique [0002] The open compartment refers to a truck compartment with end walls, side walls, and floors without a roof, which is open upwards. It is mainly used for the transportation of bulk goods such as coal, ores, mining and construction materials, wood, and steel, and can also be used to transport small weight. of mechanical equipment. If the goods to be shipped are covered with tarpaulins or other awnings, they can be used instead of boxcars to carry goods that are afraid of rain. Therefore, open carriages have great versatility, and are the largest in the composition of 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 caus...
