Description

Speed roller supporting device capable of being installed on upper side of belt support Technical Field The utility model belongs to the technical field of coal mine conveying equipment, and particularly relates to a speed roller supporting device applied to a coal mine conveying belt. Background The mining speed sensor roller is used for hoisting the upper surface of the belt of the coal mine belt conveyor through the bracket, and is contacted with the belt for friction rotation. Because there are many debris on the belt in the belt transportation process, have metal and nonmetal, and the belt openly adheres to a lot of coal dust cinder moreover, can often receive coal dust and metal foreign matter's influence near being close to the coal bunker, the probe of response is covered by muddy water or foreign matter shelters from the signal detection of influence speed sensor, brings the puzzlement for life and maintenance. And the speed sensor is installed on the surface of the belt, and the risk of falling and flying along with the belt still exists, if falling due to loosening of a regulating ring or a fixing screw, the idler wheel can move along with the belt at a high speed, and the splash roller is uncontrolled and easily causes personnel damage, so that potential safety hazards are brought. Disclosure of utility model In order to solve the technical problems that in the prior art, under severe environments, a mining speed sensor is used for a long time, and an inductive probe is covered by muddy water or shielded by foreign matters to influence the signal detection of the speed sensor, the utility model provides the speed roller supporting device which can be arranged on the upper side of a belt bracket, foreign matters on a roller of the speed sensor can be automatically removed through the side-mounted bracket, meanwhile, the effective friction between the roller and the belt is enhanced, the speed detection precision is improved, and meanwhile, the risk of falling, flying and hurting people is reduced.
