Embodiment Construction

[0012] A railway car roof opening and closing mechanism, such as figure 1 , 2 As shown, it includes a rotating shaft 3 that is controlled by a driving mechanism and runs through the car body 2 below the top cover 1, and bell cranks 4 located on both sides of the top cover. , the other end is hinged with the top cover one end by round pin 5, and two top cover rollers 6 are installed at the top cover other end, and the car body is provided with the roller track 7 that cooperates with the top cover roller. The roller track 7 is a broken line shape formed by connecting end to end of several straight line sections. The broken line shape of the roller track is generally: the opening process of the top cover is composed of uphill sections with different small slope angles, and the top cover closing process is composed of downhill sections with different small slope angles. The slope section is composed of; the end of the roller track 7 is provided with a shoulder 8. The driving mec...

Abstract

The invention relates to the technical field of railway vehicles, in particular to a railway vehicle top cover opening and closing mechanism which solves the problems that most of existing railway vehicles have no top covers or operators need to climb up the tops of railway vehicles having top covers to open or close the top covers, materials are likely to be exposed to the rain and damaged, and time and labor are wasted during operation. The railway vehicle top cover opening and closing mechanism comprises a rotary shaft and cranks, wherein the rotary shaft is controlled by a driving mechanism and penetrates through the interior of a vehicle body below a top cover, and the cranks are located on the two sides of the top cover; the two ends of the rotary shaft extend out of the two sides of the vehicle body; one end of each crank is hinged to the rotary shaft, and the other end of each crank is connected with one end of the top cover through a round pin; the other end of the top cover is provided with two top cover rolling wheels; the vehicle body is provided with rolling wheel tracks matched with the top cover rolling wheels; each rolling wheel track is formed by connecting a plurality of linear segments in an end to end mode. The operators can open and close the top cover without climbing up the vehicle top. The railway vehicle top cover opening and closing mechanism is simple in structure, good in reliability, low in cost and capable of being popularized and applied to installation of top covers of various types of railway vehicles.

Description

technical field [0001] The invention relates to the technical field of railway vehicles, in particular to a top cover opening and closing mechanism of railway vehicles. Background technique [0002] Most of the railway vehicles currently in operation are uncovered vehicles. When it is windy and rainy, the bulk cargo loaded in the vehicle may not only be damaged, but also easily leak out and pollute the surrounding environment. The existing covered vehicles basically require the operator to climb on the roof to open and close the roof, which is laborious, time-consuming and dangerous. There are very few covered hopper vehicles that can be opened and closed by wind, and the opening and closing mechanism is relatively complicated. The cost is high, the reliability is poor, and the required wind pressure is high. Contents of the invention [0003] The present invention provides a railway vehicle in order to solve the problems that most of the existing railway vehicles are u...
