Sensor system of underground mining vehicles and underground mining vehicle comprising sensor system

A sensor system for an underground mining vehicle, which system is arranged to be fastened at a perimeter of the underground mining vehicle, comprising a sensor and a stand, wherein the stand comprises:

• a mounting plate for fastening the stand to the underground mining vehicle,
• a movable plate, having an inner end and an outer end, fastened moveably to the mounting plate,
• a guard member comprising a rim, which guard member is provided at the outer end so that the rim extends over the outer end of the movable plate, and
• a biasing member fastened between the movable plate and the mounting plate;
• wherein the sensor is fastened to the movable plate so that the sensor is between the rim of the guard member and the inner end of the movable plate,
• wherein the movable plate has two positions:
• a resting position, wherein the rim of the guard member is extending outside of the underground vehicle perimeter when the system is fastened to the underground mining vehicle, and
• a retracted position, wherein the outer end and the sensor are retracted inside the perimeter of the underground mining vehicle when the system is fastened to the underground mining vehicle, and
• wherein the biasing member is biasing the movable plate to the resting position.
