Railway axle counting sensor

Abstract

The invention relates to the field of railway transportation equipment, in particular to a railway axle counting sensor which is higher in detection stability. The railway axle counting sensor comprises a pair of rails and a base arranged at the bottoms of the rails. Each rail is correspondingly provided with at least one axle counting sensing device, wherein each axle counting sensing device is composed of an axle counting sensor body and a sensor protection shell connected to the outside of the axle counting sensor body in a sleeved mode, all the axle counting sensing devices are arranged between the rails, and the sensor protection shells are fixedly connected with the base. By using the base at the bottoms of the rails ingeniously, fixing of the axle counting sensor bodies is indirectly achieved in the manner that the sensor protection shells are fixedly connected with the base instead of the manner that the axle counting sensor bodies are directly fixed to the rails. The rails and peripheral structures of the rails are reasonably utilized, and the railway axle counting sensor is ingenious is design, significant in effect and capable of being applied to railway sections where running conditions of a locomotive on a railway need real-time detection.

Description

technical field [0001] The invention relates to the field of rail transportation equipment, in particular to a rail axle counting sensor. Background technique [0002] In the current rail transit operation, the system dispatching control center must realize the monitoring and automatic dispatching of the operation of the vehicles on the rails. In order to realize such scheduling, it is necessary to carry out real-time statistics on the locomotives on the rails. The technical means commonly used at present is to drill a hole on the side waist of the rail, and then the sensor is fixedly installed in the mode of drilling on the side waist of the rail to carry out. However, due to factors such as the vibration of the locomotive passing by, such an installation method will cause its fixity to gradually decrease with the passage of time, resulting in loosening of the sensor installation, and eventually the sensor cannot accurately detect the signal of the train passing . In add...

Problems solved by technology

However, due to factors such as the vibration of the locomotive passing by, such an installation method will cause its fixity to gradually decrease with the passage of time, resulting in loosening of the sensor installation, and eventually the sensor cannot accurately detect the signal of the train passing

In addition, because the sensor is exposed to the outside world, once the locomotive slideway occurs, the sensor will be easily damaged by the locomotive, resulting in large economic losses
