Abstract

The invention provides a top cover opening method and system of a wagon. The method includes the steps of firstly, detecting the position of a carriage of the wagon; secondly, when the carriage is driven to a preset top detaching position, in the driving process of the wagon, detaching a top cover of the carriage, wherein the preset cover detaching position is in front of a carriage loading position; thirdly, when the carriage is driven to a preset cover assembling position, in the driving process of the wagon, installing the top cover on the carriage, wherein the preset cover assembling position is located behind the carriage loading position. The opening and closing of the top cover of the carriage are completed in the driving process of the wagon, the continuous loading of the wagon isrealized, and the wagon loading efficiency is improved; the requirement for loading a vehicle through a loader can be met, and environment pollution and energy loss are avoided.

Description

technical field [0001] The invention relates to the technical field of railway transportation, more specifically, to a method for opening and closing a top cover of a railway freight car, and the invention also relates to a system for opening and closing a top cover of a railway freight car. Background technique [0002] At present, bulk goods such as coal are mainly transported by railway trucks. There are two main types of railway wagons for transporting coal in China: one is gondola wagons; the other is bottom-opening hopper wagons matched with ground facilities. The above-mentioned vehicles are all without a roof structure. During the operation of the vehicle, due to the effect of aerodynamic force, the pulverized coal will be blown out of the compartment, causing pollution to the environment; meanwhile, serious waste is accumulated over time. [0003] In order to realize the environmental protection of coal railway transportation, the top of the open-top railway wagon ...
