Mining track car arrester

The utility model discloses a mining track car arrester, which comprises a clamping plate I, a clamping plate II and a bolt pair. The clamping plate I and the clamping plate II are oppositely fixedly arranged to form a track clamping structure; the bolt pair penetrates through holes arranged between the lower end of the clamping plate I and the lower end of clamping plate II; and a sealing ring surrounding a track is formed by the clamping plate I, the clamping plate II and the bolt pair. When in use, the bolt pair is disassembled, a track needing car arresting is clamped by the clamping plate I and the clamping plate II, and the bolt pair is enabled to penetrate through the through holes to be screwed tightly, thereby the car arrester can be fixed onto the track for arresting cars.
