The invention discloses a bidirectional hook type braking car. The bidirectional hook type braking car comprises two hook type braking devices and a braking rail. Each hook type braking device comprises a pull rod which is connected with a front mine car and a rear mine car. The other end of each pull rod penetrates through a guide sleeve. A compressed spring I is connected to the inner side of each guide sleeve. Each pull rod is sleeved with the corresponding compressed spring I. The end of each pull rod is connected with a guide plate through a nut. The other end of each compressed spring I is in contact with the corresponding guide plate and drives the guide plate to slide inside the corresponding guide sleeve. Each hook type braking device further comprises a connecting rod and a braking rod. Each pull rod is hinged to the corresponding connecting rod through a hinge pin I. Each connecting rod is hinged to the corresponding braking rod through a hinge pin II. A braking sleeve on each braking rod is engaged with tooth grooves in the braking rail. Each braking rod is hinged to an axle. The braking car is provided with a reversing device so that reversed braking can be achieved. The compressed springs are arranged on the braking rods so that braking force can act on the braking car in a buffered mode. By means of the braking devices of the braking car, fast braking can be achieved, no power source needs to be arranged additionally, manufacturing cost is low, installation is easy, and maintenance is convenient.
