Longitudinal telescopic railway wagon top cover

Abstract

The invention discloses a longitudinal telescopic railway wagon top cover. The top cover comprises a rail assembly, a sliding block and shed rod system and a driving system. Rails are integrally arranged on two sides of a side wall of a vehicle body in an inverted-L shape, and the sliding block and shed rod system comprises a tail sliding block and shed rod assembly, a driven sliding block and shed rod assembly and a driving sliding block and shed rod assembly which operate along the rails. Each assembly comprises a shed rod for supporting and connecting awning cloth and a sliding block whichruns along the rails and supports the shed rod; power sources such as a motor or a hydraulic motor and the like are adopted, the driving sliding block and shed rod assembly are driven by a transmission mechanism to move on the rails, and the awning cloth covers an open top; and when the top cover is opened, the transmission mechanism drives the driving sliding block to directly act on the driven sliding block, and recycling of the shed rod and the awning cloth is achieved. Due to arrangement of the rails, the shed rod can be conveniently placed on an outer side of an end wall of a wagon body after being retracted, and the wagon body is fully opened to adapt to tippler unloading conditions; and the top cover is made of light-weight soft awning cloth, the weight is light, and maintenance cost is low.

Description

technical field [0001] The invention belongs to the technical field of design and manufacture of railway freight car vehicles, in particular to the technical field of design and manufacture of a roof of railway freight car vehicles, and in particular relates to the design and manufacture of a longitudinally telescopic roof of railway freight car. Background technique [0002] my country's railway coal transport vehicles mainly include gondola cars and coal hopper cars, both of which adopt an open-top structure. When a train full of coal is running at a train intersection, in a curved section, and when the train is braking, due to the effect of relative airflow, coal dust will be raised with the airflow , eventually floating and scattered on both sides of the line. At present, domestic and foreign railway coal transportation mainly adopts the method of spraying disposable binder on the surface of coal to prevent coal dust during operation, but there are problems of high cost o...

AI Technical Summary

Problems solved by technology

This type of top cover is easy to interfere with the end ring and pressure head of the dumper. It can only be matched with a specific type of dumper, and the versatility is not good; If the degree of tightness is small, it may cause the block of coal to be stuck and affect the problem of unloading; the top cover and the frame are connected by one-sided hinges, and the service life is greatly shortened under the long-term vibration and impact of the goods; After unloading, the operator cannot observe the condition inside the vehicle. If there is a lot of coal residue, the vehicle may be unbalanced and affect driving safety.
