Gravity-type self-locking method and mechanism for vehicle cover plates

Abstract

A gravity-type self-locking method and mechanism for vehicle cover plates are provided. A cover plate is connected to a sliding rack; a rocking block is hinged to a sliding rack and is fixed to a compartment via a retaining seat; the rocking block is constantly kept vertically downward under its gravity action, so that the compartment tilts for discharging; when the sliding rack and the cover plate move on the top of the compartment under the gravity action, the rocking block may abut to the retaining seat; meanwhile, the retaining block can block the sliding rack and the cover plate from moving; therefore, it is avoided that when the compartment tilts for discharging, the cover plate moves to cover the top of the compartment so as to block discharging. The gravity-type self-locking methodand mechanism for vehicle cover plates have the advantages that it can be avoided that the cover plate covers the top of a compartment during discharging, and discharging being further blocked by thecover plate is avoided; discharging can be carried out normally; the retaining seat may block the rocking block under automatic locking, and no manual operation is involved.

Description

technical field [0001] The invention relates to an auxiliary mechanism of a rail vehicle, in particular to a locking method and a locking mechanism for a roof cover. Background technique [0002] Railway freight open car refers to a freight car that has end walls, side walls, floors and no roof, and is open upwards. It is mainly used for transporting bulk goods such as coal, ore, mining construction materials, timber, and steel. It can also be used to transport light weight goods. Equipment. Therefore, gondola cars have great versatility and are the largest number of freight cars. At present, there are about 300,000 gondola cars in the whole railway, accounting for more than 50% of the total number of freight cars. [0003] In order to prevent the coal and other items in the compartment from being spilled along the railway line during the transportation of the open railway freight car, causing damage to the surrounding environment, it is generally necessary to cover the top...

AI Technical Summary

Problems solved by technology

At present, when covering the roof of the carriage or dismantling the canvas, it is all done manually, but in this way, the labor intensity of the workers is high and the work efficiency is low

[0004] However, if the foldable cover plate is used to cover the top of the compartment, it is easy to have the problem that the cover plate moves by itself during unloading and affects the normal unloading.
