Front end opening and closing mechanism for guide groove type railway vehicle

Abstract

The invention discloses a front end opening and closing mechanism for a guide groove type railway vehicle. The front end opening and closing mechanism comprises a glass steel fixing cover, a glass steel head cover and a mechanism assembly. The glass steel fixing cover and the glass steel head cover are arranged at the front end of the mechanism assembly. The mechanism assembly comprises an upper framework assembly, a lower framework assembly, an upper sliding plate assembly, a lower sliding plate assembly, upper rotary arms, lower rotary arms, synchronizing rods, lower linear sliding rails, an air cylinder, upper rotary supporting pins, lower rotary supporting pins, guide pins and an electrical control part. The upper framework assembly is connected with the lower framework assembly through the synchronizing rods. Meanwhile, guide grooves are formed in the upper framework assembly and the lower framework assembly and used for controlling the rotary radiuses and angles of the upper rotary arms and the lower rotary arms to adapt to complex environment and new head types. Based on the rotating and composite sliding principle, the space utilization rate is high, and the left and right opening and closing synchronous stopping performance and high efficiency are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of vehicle equipment machinery manufacturing, and in particular relates to a front end opening and closing mechanism for a guide groove type rail vehicle. Background technique [0002] At present, rail vehicles (such as bullet trains and high-speed rails) are the means of transportation commonly used by people in daily life. In order to realize the reconnection or return rescue of vehicles, front-end opening and closing mechanisms are usually installed at both ends of the vehicle. The front-end opening and closing mechanism is an important part of the EMU. In the non-reconnected state of the vehicle, the opening and closing mechanism is in the closed state. At this time, the front-end hood hatch is closed, so that the rail vehicle has a good aerodynamic shape to prevent blades , the entry of dust, ice and snow, and protect the couplers and other facilities inside the front-end hood; in the reconnected state ...

AI Technical Summary

Problems solved by technology

[0006] The technical problem to be solved by the present invention is to provide a front-end opening and closing mechanism for rail vehicles with guide grooves, which solves the problem that the opening and closing mechanism is not easy to open smoothly under the constraints of compact space and shape in the prior art, and it is easy to interfere with other components and cannot At the same time, it has high efficiency, stability and high strength, and cannot meet the opening and closing requirements of various working conditions.
