A rail vehicle contact obstacle detection device

Abstract

The invention discloses a detection device for a contact-type obstacle of a railway vehicle. The detection device comprises a detection beam, a shifting connection plate, a travel switch and two elastic supports which are symmetrically arranged in a matching manner, wherein the detection beam is fixedly connected with front end supporting arms of the elastic supports respectively; the shifting connection plate is fixedly connected to the front end supporting arms of the elastic supports; a through hole is formed in the shifting connection plate; rear end supporting arms of the elastic supports are fixedly connected with the travel switch; and a shifting pin is arranged on the travel switch and inserted into the through hole. The detection device has the benefits as follows: the device structure is simple, and the elastic supports are deformed greatly, so that the travel switch is triggered to send a signal, and the obstacle is detected. Heights of the detection beam and a switch triggering mechanism of the detection device are adjustable, so that heights of the detection beam and a track are adjustable, and the detection device is applicable to different types of railway vehicles.

Description

technical field [0001] The invention relates to the technical field of transportation, in particular to a rail vehicle contact obstacle detection device. Background technique [0002] In rail transportation, the obstacle detection device mainly detects objects existing in the track to avoid damage to rail vehicles caused by obstacles. At present, subway stations are mainly judged by using cameras placed above the tracks. However, this solution cannot fully meet the needs, because this solution can only detect obstacles in the monitoring area; in bad weather, if there are obstacles in front of the vehicle , the rail vehicle driver will be difficult to detect, and thus may not be able to avoid obstacles causing damage to the rail vehicle. [0003] Existing patent No. such as CN101165475A relates to a device and method for detecting the presence of objects, which can detect the presence of objects in the detection area, but cannot detect the presence of objects outside the det...

At present, subway stations are mainly judged by using cameras placed above the tracks. However, this solution cannot fully meet the needs, because this solution can only detect obstacles in the monitoring area; in bad weather, if there are obstacles in front of the vehicle , the rail vehicle driver will be difficult to detect and may not be able to avoid obstacles causing damage to the rail vehicle

[0003] Existing patent numbers such as CN101165475A refer to a device and method for detecting the presence of objects, which can detect the presence of objects in the detection area, but cannot detect the presence of objects outside the detection area.
