Embodiment Construction

[0015] The specific embodiments of the present invention will be further described in conjunction with the accompanying drawings, and the embodiments are used to illustrate the present invention, but not to limit it in any way.

[0016] The arc roof 1 is designed on the coverless hopper car, and according to the loading width of the elevated feed bin, a 1-meter-wide charging opening is opened at the center of the arc roof 1. In order to prevent rainwater from entering from the charging port, an arc movable top cover 4 with a width of 1.1 meters and rubber sealing strips is set above the charging port. The movable top cover 4 can pass through two Small two-way acting air cylinder 5 controls its flexible opening and closing.

[0017] Two small two-way acting air cylinders 5 are controlled by a control valve in the operation box 2 on the wind control console, which is easy to operate. In order to ensure the synchronization of the two small double-acting air cylinders 5, a one-wa...

Abstract

The invention belongs to lorry part technique field, in particular to a movable roof for railway coverless hopper lorry, which solves a problem in the prior art that railway coverless hopper lorry can not meet the transportation requirement of powder goods. The movable roof is characterized in that an arc roof is arranged on the coverless hopper lorry; a feeding inlet is arranged on the arc roof; an arc movable top cover which can do rotational slide along the arc roof is arranged on the feeding inlet; a rocker is arrange on both ends of the movable top cover; the lower part of the rocker is hinged with the body of coverless hopper lorry; the rocker is connected with a driving mechanism; a limit device and a locking mechanism are arranged on the rocker. The invention has the advantage of rain and water proofing, flexible pneumatic opening and closing of the fully long movable top cover, and fills a domestic gap in the field and lays a foundation for further development of the hopper lorry with cover.

Description

technical field [0001] 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. Background technique [0002] At present, the self-unloading hopper trucks used to transport bulk cargoes such as lime, ore, and coal in China are coverless hopper trucks, which easily pollute the surrounding environment when the bulk cargo is shipped in windy and rainy weather. With the increasing awareness of human environmental protection, it is an inevitable development trend for railway vehicles to add roofs that can prevent rain and wind. All types of hopper cars in China are top loading and unloading. In order to facilitate loading of goods, the top cover of the covered hopper car should be a movable full-length top cover, but it is very difficult to meet this requirement. Contents of the invention [0003] In order to solve the problem that the railway hopper car without a ...
