An emergency braking extension device includes an emergency braking extension loop, a first emergency braking extension train line and a second emergency braking extension train line. The emergency braking extension loop has a protective circuit breaker, a normally open contact of an emergency braking button, and an emergency braking extension relay, which are sequentially connected in series. A normally open contact of the emergency braking extension relay is connected in series to a pantograph lowering control loop. A first normally closed contact and a second normally closed contact of the emergency braking extension relay are connected in series to a return line and a power supply negative loop of a train emergency braking control loop, respectively. A third normally closed contact of the emergency braking extension relay is connected in series to a control loop of a bypass cut-off circuit of a train emergency braking execution loop.
