Integral turnover type car roof for railway sealed transportation of long and large goods

Abstract

The invention relates to an integral turnover car roof for railway sealed transportation of long and large goods, which comprises a car roof frame, a car roof cover, a car roof cover, a car roof cover, a car roof cover, a car roof cover, a car roof cover, a car roof cover and a car roof cover, and is characterized in that one side is movably connected with the top of one side wall of a car body; the car roof plate is arranged on the car roof frame in a covering manner; the roof fixing supports are circumferentially arranged along the top of the side wall and the top of the end wall of the vehicle body and used for supporting and limiting the roof frame; the two car roof opening and closing mechanisms are arranged in the two ends of the car roof frame respectively; one end of each car roof opening and closing mechanism is connected with the end wall, and the other end of each car roof opening and closing mechanism is connected with the car roof frame. Large goods can be loaded and unloaded from the top by integrally opening the cover, the length of the goods loading and unloading opening is close to the whole length of the vehicle body, the vehicle roof is sealed during transportation, and large goods with storage and transportation temperature requirements can be cooperatively transported.

Description

technical field [0001] The invention relates to the technical field of railway transport vehicles, in particular to an integral overturned roof used for railway sealed transport of long and large goods. Background technique [0002] A railway boxcar is a vehicle with end walls, side walls and a roof. It can transport all kinds of goods that are afraid of sunlight and moisture. The goods are generally loaded and unloaded through the side door. Due to the limitation of the opening size of the door hole, it cannot be loaded with larger dimensions. large cargo. In order to solve the problem of loading and unloading large-scale goods, my country has begun to study special boxcars with movable roofs, and goods can be loaded and unloaded from the top of the vehicle. [0003] The currently disclosed movable roof forms of railway freight cars mainly include: split-level casement type, folding type, hanging cover type, split-overturning type, and integral overturning type. Split-lev...

AI Technical Summary

Problems solved by technology

Split-level flat-opening, folding, and suspended roofs, the roof opening is only a part of the entire roof, and it is still impossible to load and unload longer cargo

Although the split flip type and integral flip type can fully open the roof, one end of the driving device is placed on the vehicle chassis or at a relatively low vertical position inside the vehicle, which affects the entry of personnel at the end door or the loading and unloading of goods. , and its driving device is complex, taking up a lot of space in the car, making the car unsuitable for loading longer cargo

At the same time, the above types of roofs currently only have the function of rainproof, without sealing function, and cannot meet the function of transporting goods with airtight requirements.
