Movable top cover of railway wagon and railway wagon

Abstract

The invention discloses a movable top cover of a railway wagon and the railway wagon. The movable top cover includes a left top cover and a right top cover, the end of the left top cover is connectedwith one end of a left rocker, the end of the right top cover is connected with one end of a right rocker, the other end of the left rocker is installed on a left fixed rotary fulcrum of a wagon body,and the other end of the right rocker is installed on a right fixed rotary fulcrum of the wagon body; the end of the wagon body is provided with a driving mechanism which includes a driving device and a connecting rod mechanism, and the lower ends of the left rocker and the right rocker are provided with a left rocker arm and a right rocker arm; and the driving device is connected with the connecting rod mechanism, the connecting rod mechanism is connected with the left rocker arm and the right rocker arm, and the connecting rod of the connecting rod mechanism has a dead point passing strokethat drives the left top cover and the right top cover to move first towards each other and then backwards during the opening process. The movable cover has better locking performance and high safetyand reliability, the top cover opening accidentally in the running process of the wagon can be effectively prevented, and environmental pollution can be effectively prevented.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a movable roof of a railway freight car. The invention also relates to a railway wagon provided with said movable roof. Background technique [0002] Most of the coal hopper cars are open-top structures. Coal dust and leakage are a major problem that plagues railway coal transportation. It not only causes waste of resources and economic losses, but also pollutes the environment along the railway. With the enhancement of awareness, coal dust and leakage have increasingly become social problems that need to be solved urgently in railway transportation. [0003] At present, railway coal transportation mainly adopts the method of spraying dust suppressant on the coal surface to realize coal environmental protection transportation, but there are problems of high spraying cost and poor environmental protection effect. [0004] In addition, it is also possible to prevent coal du...

AI Technical Summary

Problems solved by technology

[0005] The overall structure of the movable roof of the above-mentioned hopper car is complex and heavy, which reduces the economy of transportation, and is not suitable for trains with long transportation distances and long marshalling; The torque is large, and the requirements for the cylinder are high; moreover, the top cover only relies on the cylinder to lock, which is poor in safety and reliability.

In addition, the arc shape of the side wall cannot make full use of the limit, and a lot of volume space is wasted. The vehicle with this roof has a large dead weight coefficient, and the vehicle performance parameters are lagging behind.
