Abstract

The disclosed track sensor is weighing sensor. Outline of the track sensor is in shape of track. Plug slot is setup on stress surface, and connector is setup in the plug slot. Being setup on low part of connector, corresponding plugging tongue is matched and connected to the plug slot. Length of the connector is equal to length of the sensor. The invention solves disadvantage of poor wearability of track type sensor, and raises service life of track type sensor.

Description

technical field [0001] The invention relates to a sensor, in particular to a track scale sensor. Background technique [0002] At present, the track scales are used to measure the load-carrying vehicles on the track, and most of them use track sensors to measure the weight. This can make the track scales realize no foundation pit and no weighing platform, which greatly saves equipment costs and installation and maintenance costs. There are three kinds of existing track sensors: one is to directly paste resistance strain gauges on the rail to form a Wheatstone bridge, but this method has technical problems such as sensor patching, compensation, and sealing processes, which are complicated and difficult to implement. The other is to drill a hole on the rail and insert a load cell into the hole. This method has low sensor measurement accuracy, and it is difficult to process the installation hole on site, and it is not easy to realize. What is more scientific is the third type,...
