Embodiment Construction

[0026] Embodiments of the present invention will be explained below in conjunction with the accompanying drawings.

[0027] Such as figure 1 , Figure 7 As shown, it is composed of the front end frame 1, the cab sealing structure 2, the connecting seat 3, the coupler mounting base 4, and the anti-collision device 5. The coupler mounting base 4 and the anti-collision device 5 are fixedly connected by bolts, and the material of its structural parts is 2.5 Use Q310NQL2 below mm, use Q345NQR2 above 2.5mm, and connect other parts by welding (all welding in this article is inert gas shielded welding). The sealing structure 2 of the driver's cab is welded and fixed to the front end frame 1 to form a sealed overall structure at the front. The anti-collision device 5 is fixed to the front part of the coupler mounting seat 4 by bolts.

[0028] Such as figure 2 As shown, the front end frame 1 includes a U-shaped driver's cab frame 14 arranged in a horizontal direction, and two suppo...

Abstract

The invention relates to a digital railway vehicle cab framework which comprises a front-end framework, a cab sealing structure, a vehicle connecting seat, a coupler mounting seat and an anti-collision device, the cab sealing structure is welded and fixed to the front-end framework to form a front sealing integral structure, and the sealing integral structure is welded and fixed to the upper portion of the coupler mounting seat; the vehicle connecting seat is welded and fixed to the front portion of the coupler mounting seat, and the anti-collision device is fixed to the front portion of the coupler mounting seat through bolts. The framework has the characteristics of simple structure, high production efficiency and low cost. The cab is free of permanent deformation and mainly comprises the front-end framework, the anti-collision device, the coupler mounting seat and the like, the anti-collision device is connected with a vehicle body through bolts, and replacement after collision in later operation is facilitated.

Description

technical field [0001] The invention relates to a skeleton structure of a digital rail vehicle driver's cab, and belongs to the technical field of rail vehicle body structures. Background technique [0002] The digital track is a virtual track composed of magnetic tags (or magnetic nails) buried along the line as a positioning reference, which is coded and digitized. It is a virtualized and digitalized replacement of the physical rail track. The vehicle follows the digital track on its own. In 2020, the applicant developed a digital rail rubber-tyred vehicle, which can run on ordinary roads such as tunnels, elevated roads and grounds that meet the requirements of the project's line conditions. The running part is rubber wheels. The car body is made of carbon steel tailor-welded, but its load-carrying capacity can no longer meet the demand for higher strength car body at a higher speed level. The existing driver's cab structure cannot simultaneously meet the requirements of ...
