Embodiment Construction

[0015] The specific embodiments of the present invention will be further described with reference to the accompanying drawings, and the embodiments are used to illustrate the present invention without any restriction on it.

[0016] An arc roof 1 is designed on the hopper car without a cover. According to the loading width of the elevated silo, a 1 meter wide loading port is opened in the center of the arc roof 1. In order to prevent rainwater from entering from the loading port, an arc movable top cover 4 with a width of 1.1 meters and equipped with rubber sealing strips is set above the loading port. The movable top cover 4 can pass through the two in the form of wind as required. The small double-acting air cylinder 5 controls its flexible opening and closing.

[0017] The two small double-acting air cylinders 5 are controlled by a control valve in the operation box 2 on the air control console, and the operation is convenient. In order to ensure the synchronization of the two ...

Abstract

The invention belongs to the technical field of components for railway wagons, and in particular relates to a movable top cover for railway wagons without a cover hopper, which solves the problem that the hopper wagons without a cover in the prior art cannot meet the transportation requirements of bulk goods. A movable roof for a railway coverless funnel car, characterized in that the coverless funnel car is provided with an arc roof, the arc roof is provided with a charging port, and the charging port is installed to rotate along the arc roof. Sliding circular-arc movable top cover, two ends of the movable top cover are provided with a rocker, the lower end of the rocker is hinged on the body of the hopper car without a cover, the rocker is connected with the driving mechanism, and a limit device and a locking mechanism are arranged on the rocker. The invention has the following beneficial effects: the long movable top cover that can prevent rain and wind and can be flexibly opened and closed by wind power fills the gap in the country and lays a certain foundation for the further development of the covered hopper car in the future.

Description

Technical field [0001] The invention belongs to the technical field of parts for railway freight cars, and in particular relates to a movable roof for railway hopper cars without a cover. Background technique [0002] At present, domestic dump trucks for bulk cargoes such as lime, ore, coal, etc. are all capless hopper trucks, which are likely to pollute the surrounding environment when bulk cargo is shipped in windy and rainy weather. With the increasing awareness of human environmental protection, it is an inevitable development trend to increase the roof of railway transportation vehicles that can prevent rain and wind. All types of hopper cars in China are loading and unloading. In order to facilitate the loading of goods, the top cover of the hopper car with a cover should be a movable, full-length top cover, but it is difficult to meet this requirement. Summary of the invention [0003] In order to solve the problem in the prior art that the railway hopper car without a co...
