Method and device for protection against guiding loss for a guided vehicle

摘要

A guided vehicle includes a guidance unit having first and second V-mounted guide pulleys resting on first and second running surfaces of a guide rail. The running surfaces are on sides of a median longitudinal plane of the guide rail and each pulley has a flange for freely gripping the guide rail. A device and method protecting against loss of vehicle guidance include a section with longitudinal height fixed along its length to a guide rail part, between running surfaces, the section having a cross-section guiding the unit during derailment or loss of guidance thereof with the section fixed to the guide rail part. The cross-section geometry holds the first pulley flange on the side of the median plane including the first pulley running surface and the second pulley flange on the side including the second pulley running surface. A device fixes the section to the guide rail.

主权项

1. In a guided vehicle equipped with a guidance unit including first and second guide pulleys mounted in a V and intended to rest on respective first and second running surfaces of a guide rail with the first and second running surfaces positioned on respective sides of a median longitudinal plane of the guide rail and each of the guide pulleys having a flange permitting free gripping of the guide rail, a device for protecting against a loss of guidance of the guided vehicle, said device comprising:
a section having a length, having a longitudinally-extending height (h>0) and being configured to be fixed along said length to at least a part of the guide rail between the first and said second running surfaces; said section having a cross-section configured to guide the guidance unit during a derailment or loss of guidance of the guidance unit with said section fixed to the part of the guide rail; said cross-section having a geometry configured to hold the flange of the first guide pulley on the side of the median plane having the running surface of the first guide pulley and configured to hold the flange of the second guide pulley on the side of the median plane having the running surface of the second guide pulley; and a device for fixing said section to the guide rail.
