Gondola car, movable top cover and driving device of movable top cover

Abstract

The invention discloses a gondola car, a movable top cover and a driving device of the movable top cover. The driving device of the movable top cover comprises a transmission mechanism for being arranged on a car body, the transmission mechanism comprises a transfer part for installing the top cover and capable of moving in the length direction of the car body, a touching part fixed to the transfer part, and a contact device capable of being connected with the touching part in an abutting mode, wherein when the car body travels in the length direction of the car body, the contact device movesrelative to the traffic car body in the length direction of the car body, and the contact device can drive the transfer part to move in the length direction of the car body to open and close the top cover through the touching part. According to the driving device of the movable top cover, the contact device moves relative to the traffic car body, and thus the transmission mechanism is driven to operate to open and close the top cover. The contact device is not arranged on the car body, compared with the prior art, a power device is not required to be installed on the car body, the weight of the whole car is decreased, and the transport economical efficiency is improved; and the cost is also lowered.

Description

technical field [0001] The invention relates to the technical field of railway freight car transportation, and more specifically relates to an open car, a movable top cover and a driving device thereof. Background technique [0002] The gondola car is a commonly used railway freight car, which mainly transports bulk items such as coal. The loading port of the gondola car is an open rectangular structure. During the transportation process, dust and other phenomena will occur, which not only causes the loss of coal transported on the vehicle and reduces economic benefits, but also causes great pollution to the environment. [0003] At present, the problems referred to above are solved by setting a movable roof at the loading port of the gondola car. The movable top cover mainly includes a top cover and a driving device for opening and closing the top cover. Wherein, the driving device is installed on both sides of the top of the car body, and the driving device mainly includ...

AI Technical Summary

Problems solved by technology

[0004] In the above structure, the driving components need to be arranged on the vehicle body, and the weight of the entire vehicle body is relatively large, resulting in poor transportation economy

[0005] In addition, when the top cover is fully opened, the top cover is stacked on one end of the loading port, which will occupy part of the area of ​​the loading port or require a certain space to be reserved at the end of the open car, and is not suitable for railway dumper operations.
