Embodiment Construction

[0013] In order to better understand the technical solutions of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0014] The present invention is a compressed gas multi-stage buffer energy-absorbing device, such as figure 1 Shown; The multi-stage buffer energy-absorbing device is installed on the front end of the train through the mounting plate 1. When the multi-stage buffer energy-absorbing device is in working condition, the high-pressure gas storage chamber 2 is first filled with gas through the air intake device 3, and then the high-pressure gas storage chamber is discharged through the intake check valve 4 on the second compound flange 6. The gas in the chamber 2 is charged into the buffer air spring 7 . When bumping into the anti-climbing tooth 11, the whole device is subject to a huge impact force, and what is squeezed is the primary energy-absorbing tube 12 connected to the bo...

Abstract

The invention provides a multi-stage buffer energy-absorbing device, which belongs to the technical field of rail vehicle collision tests. Including high-pressure gas storage chamber, buffer air spring and anti-climbing gear, the high-pressure gas storage chamber is connected to the mounting plate and fixed, the right wall of the high-pressure gas storage chamber has an air intake device, the left wall has an emergency air release device, and the second double flange is below It is a high-pressure gas storage chamber with an inlet check valve in the center and an outlet check valve on the left side of the center. Above the second double flange is a secondary energy-absorbing device. The lower part of the secondary energy-absorbing device is There is a buffer air spring, and the upper part is provided with a guide block. The top surface of the guide block and the secondary energy-absorbing tube is connected to the lower surface of the installation base. The lower end of the primary energy-absorbing tube is connected to the first double flange, and the upper end is connected to Anti-climbing teeth, the interior is honeycomb aluminum plate. Mainly used for collision energy absorption of rail vehicles.

Description

technical field [0001] The invention belongs to the technical field of rail vehicle collision. Background technique [0002] With the continuous development of my country's railway transportation industry, the speed of trains is also increasing. If a train collision accident occurs, it will cause damage to personnel and rolling stock. In order to avoid a large number of casualties and reduce property losses caused by train collisions, therefore The research on the passive safety of locomotives is of great significance for protecting the safety of drivers and passengers and preventing the loss of goods. The energy-absorbing device is a key link in the crash-resistant design of locomotives and vehicles. When the energy-absorbing device is impacted, the plastic deformation produced will consume energy, and at the same time produce a certain crushing stroke, which will reduce the running speed of the locomotive while absorbing kinetic energy. Contents of the invention [0003]...
