The invention discloses a traction-track bidirectionally-reversible car stopper for a coal mine operating car. The traction-track bidirectionally-reversible car stopper comprises fixing seats, stopping claws, buffer shafts, buffer springs, a rotating frame, connecting arms and car stopper hydraulic oil cylinders, wherein the fixing seats are symmetrically arranged on two sides of an iron rail, grooves are formed in the fixing seats, the stopping claws are arranged in groove areas and are hinged to the fixing seats through the buffer shafts, the buffer shafts penetrate through the fixing seats in the direction of the iron rail, two ends of each buffer shaft are respectively sleeved with the buffer springs, one end of each buffer spring is fixedly connected to the corresponding fixing seat, the other end of each buffer spring is fixedly connected to the tail end of the corresponding buffer shaft, the rotating frame is arranged at the bottom of the iron rail, the connecting arms are respectively hinged to two ends of the rotating frame, the other end of each connecting arm is in hinged connection with the bottom of the corresponding stopping claw, and the center of the rotating frame is connected with the output ends of the car stopper hydraulic oil cylinders. The traction-track bidirectionally-reversible car stopper has the advantages of achieving bidirectional controllable car stopping, achieving stable car stopping and improving the using safety.
