Vehicle anti-skid device

Abstract

The vehicle sliding prevention device is made up of the main arresting gear, the auxiliary brake, the coupled axle device and the disorbitting drill key. It is fixed in the bottom of the stock rail outside. The main arresting gear is turned to the braking position and the main shoe is turned up to the rail level, the auxiliary shoe torsion spring stores the torsion in the same time. When the sliding vehicle pulls out the main shoe, the auxiliary shoe turns to the rail level by the storing energy to brake the vehicle with the main shoe to avoid the accident. If the vehicle has the large kinetic energy and it can't stop in the preformed distance, the main shoe will go into the disorbitting drill key and become the derail to make the vehicle run off rails in the alarm punch mark inner orientation. So it has the triple safety measures of main arresting gear, the auxiliary brake and the forced disorbit.

Description

technical field [0001] The anti-running device for vehicles of the present invention is arranged on special railway lines, section pipelines, cargo lines and other lines that need to prevent slippage of standing vehicles, and belongs to the technical field of safety equipment for railway shunting operations. Background technique [0002] At present, after the railway vehicles have changed from sliding bearings to rolling bearings, accidents of vehicles slipping often occur. The anti-slip measures for domestic railways are mainly manual tightening of hand brakes, manual installation of brake shoes, and placement of anti-slip sleepers. Such cumbersome methods are labor-intensive and unsafe. There are also mechanical equipment such as derailers and vehicle anti-slip derailment devices. The anti-slip effect of the derailment device is good, but there are disadvantages such as inconvenient installation and the need to drill holes on the rail, and the spring of the auxiliary brake...

Problems solved by technology

[0002] At present, after the railway vehicles have changed from sliding bearings to rolling bearings, accidents of vehicles slipping often occur. The anti-slip measures for domestic railways are mainly manual tightening of hand brakes, manual installation of brake shoes, and placement of anti-slip sleepers. Such cumbersome methods are labor-intensive and unsafe. There are also mechanical equipment such as derailers and vehicle anti-slip derailment devices. The anti-slip effect of the derailment device is good, but it is inconvenient to install, and it needs to drill holes on the rail, and the spring of the auxiliary brake is often under stress, which is easy to fatigue and cause permanent deformation, and the action is unreliable after a long time.
