The utility model belongs to the technical field of underground ore transportation, and discloses a belt speed measuring device, which comprises a base, a connecting rod and a detection mechanism. transmission speed. The detection mechanism includes: a support part, a detection wheel, a tachometer and a follower wheel, the support part is hinged with the connecting rod; the detection wheel is rotatably arranged on the support part, and the detection wheel is tangentially arranged on one side of the belt to be detected; the tachometer It is configured to detect the rotation speed of the detection wheel; the follower wheel is rotatably arranged on the support part, and the follower wheel is tangentially arranged on the other side of the belt to be detected, so that the belt abuts between the detection wheel and the follower wheel. When the belt vibrates, the detection mechanism can still accurately measure the real-time transmission speed of the belt, avoiding the situation that the detection wheel is separated from the belt, so that the upper computer can adjust the rotation speed of the driving drum according to the accurate transmission speed of the belt to ensure the two run synchronously. |
