A lifting rod 33 parallel to the lifting rod is fixed on the outer side of the lifting rod 5 through a plurality of third connecting rods 32, and the lifting rod 19 lifts the lifting rod 5 through the lifting rod 33, so that the interference between the lifting rod 19 and the U-shaped frame 6 at the lower end of the lifting rod 5 when the lifting rod 19 is directly contacted with the lifting rod 5 is avoided.

The vertical rod 15 is provided with a sealing ring in a position passing through the lower part of the first piston cavity 10, so that the sealing property of the first piston cavity 10 is ensured.

The upper end of the first piston cavity is not sealed, so that the first piston can smoothly move downwards.

When a water filling accident occurs in a subway tunnel to cause a train to be anchored in the tunnel between two stations, the turntable 2 is started immediately to drive the conveying steel cable to run, personnel in a carriage wear the safety belt 20 in the carriage, then orderly standing at the vehicle door, buckling the sliding sleeve 24 on the safety belt 20 on the safety rod 21, and quickly hanging the hook of the safety belt 20 on the hanging ring assembly 16 at the lower end of the U-shaped frame 6 when the hanging unit moves to the vehicle door position, then the passenger leaves the carriage to move along with the conveying steel cable and pulls the sliding sleeve 24 to move along the safety rod 21 through the safety rope 23, when the sliding sleeve 24 moves to the position of the second connecting rod 22, the cut at the end part of the sliding sleeve 24 has a guiding function, under the action of the pulling force of the safety rope 23, the sliding sleeve 24 automatically rotates to the position where the avoidance groove 25 is aligned with the second connecting rod 22, so that the sliding sleeve 24 smoothly passes through the position until the sliding sleeve 24 slides down from the end part of the safety rod 21 on the carriage; if the passenger has a falling accident when the safety belt 20 hook is hooked on the lifting ring assembly 16, the passenger is pulled by the safety rope 23, and the sliding sleeve 24 rotates to the position where the groove 25 faces upwards and the sliding sleeve 24 cannot rotate under the action of the downward pulling force of the safety rope 23, so that the sliding sleeve 24 is blocked by the second connecting rod 22 and cannot pass through the second connecting rod 22, and the passenger is ensured not to be washed away by water flow.

When the hanging unit moves along with the conveying steel cable, the lifting rod 5 moves to the position of the lifting rod 19, the lifting rod 19 lifts the hanging rod 5 to the horizontal position through the lifting rod 33, the U-shaped frame 6 is buckled on the second conveying steel cable 4, if no person is carried on the hanging ring assembly 16 below the U-shaped frame 6, the clamping block 17 does not extend upwards, the grooved wheel 8 can rotate in two directions, after the hanging rod 5 completely passes over the lifting rod 19, the U-shaped frame 6 falls off from the second conveying steel cable 4 under the action of the counterweight 7, and the hanging rod 5 is in a vertical state again; if a passenger is hung on the lifting ring assembly 16, the first piston 12 is pulled downwards by the first vertical rod 15, the first piston 12 pushes the second piston 14 to move upwards through hydraulic oil, the second piston 14 pushes the second spring 18 and the fixture block 17 to move upwards, the second fixture block 17 is clamped in the ratchet wheel 9, the second spring 18 enables the fixture block 17 to float upwards and downwards, so that the ratchet wheel 9 and the grooved wheel 8 can rotate in a single direction, the second conveying steel cable 4 can enter the opening of the U-shaped frame 6 but cannot go out, and after the lifting ring assembly 16 is loaded with a person, the U-shaped frame 6 is lifted by the lifting rod 19 to be buckled on the second conveying steel cable 4 and cannot fall off until the passenger is unloaded; the hanging unit is used for hanging the hanging ring assembly 16 on the hanging ring assembly 16 conveniently because the hanging ring assembly 16 is lower when the passenger is unloaded, and the U-shaped frame 6 is lifted and buckled on the second conveying steel cable 4 to lift the passenger to a high position to be far away from the water surface or reduce the wading depth of the passenger when the passenger is loaded, thereby ensuring the safety of the passenger and reducing the running resistance of the conveying steel cable.

When passengers are conveyed to a passenger unloading position of the subway platform, the two cross rods 28 of the lifting ring assembly 16 move to a position between the two magnets 30, the two cross rods 28 move outwards under the action of the third spring 29 under the action of the attraction force of the magnets 30 so as to be separated, the passengers fall off the hanging unit, the sliding plate 31 is arranged below the hanging unit, and the passengers fall on the sliding plate 31 and directly slide to the platform, so that the safety and the rapidness are realized; after the passengers are unloaded, the first piston 12 moves upwards under the action of the first spring 13, the second piston 14 and the fixture block 17 move downwards, the fixture block 17 withdraws from the ratchet wheel 9, so that the ratchet wheel 9 and the grooved wheel 8 can rotate in two directions, the U-shaped frame 6 falls off from the second conveying steel cable 4, and the rescue operation is continuously carried out along with the circulating motion of the conveying steel cable between two stations.

According to the invention, passengers can be quickly and safely transferred to the subway platform from the subway tunnel by conveying the steel cable, and because the passengers are suspended at the top of the tunnel for transfer, the passengers can still be safely transferred even if accumulated water in the tunnel is deep and water flow is fast; the liftable hanging unit can be used for facilitating the hanging of the safety belt 20 hook on the hanging unit at a lower position of a passenger and ensuring that the passenger is lifted to a higher position during transferring; the sliding sleeve 24 and the safety rod 21 can prevent passengers from falling and being washed away by water flow when the passengers extend out of the vehicle door hanging hook, and the passengers can not be limited by the sliding sleeve 24 to move when the passengers do not fall accidentally; after arriving at the platform, the hanging unit can realize unloading passengers without stopping the machine, and rapidly carry out the next round of rescue operation, thereby striving for precious time for rescue work.
