However, existing wear detection methods have the following drawbacks: existing detection equipment can only obtain wear data from discrete local points on the outer surface of the slip ring and cannot capture the uneven wear distribution across the 360° surface (such as eccentric grooves caused by unbalanced brush pressure). Furthermore, according to statistics, 60% of slip ring failures are caused by undetected local areas of severe wear. Summary of the Invention
[0003] To this end, the present invention proposes a wear detection device for a conductive roller ring to solve the problems raised in the above background technology.
[0004] To achieve the above objectives, the present invention provides the following technical solution: a wear detection device for a conductive roller ring, comprising:

[0014] and a pressure column, wherein each of the sliders is connected to one end of the pressure column, and the other end of each of the pressure columns abuts against the sensing end of the corresponding pressure sensor;
[0015] Wherein, a second spring is connected between each of the sliders and the pressure sensor.
[0016] Furthermore, preferably, a guide seat fixed on the ring plate is provided in front of the fixing seat, two guide holes are provided through the guide seat, a guide ring is fixed in each of the guide holes, and the guide ring is slidably connected with the probe.

[0027] The present invention adopts the above technology and has the following beneficial effects compared with the existing technology: the device of the present invention mainly adopts a circular array of probe groups to monitor the wear morphology of the outer ring surface in real time. Compared with traditional methods, the multi-probe synchronous measurement in the present invention solves the one-sidedness problem of single-point detection and can capture the uneven wear of the entire working surface.
