When the safe weight box is used, the chain 6 drives the safety rope 12 to ascend through the pulley block 7, the weight box 9 descends, the pulley block drives the safety rope 12 to descend, the weight box 9 ascends, and after the safe weight box is in place, the weight box 9 is adsorbed and fixed by the magnetic attraction device 10 (the magnetic attraction device can be made of a commercially available product). After the magnetic attraction device 10 adsorbs the weight box 9, the safety rope 12 is in an intercepting state, namely a closing state, as shown in fig. 1, the intercepting state is a long-time state of the safety door device, the magnetic attraction device 10 outputs all acting forces of the whole mechanism at the moment, and the driving motor and the related band-type brake do not need to act, so that electric components such as the driving motor and the band-type brake can be protected, the service life of the whole mechanism is prolonged, and the magnetic attraction device is energy-saving and environment-friendly. When power failure or other faults occur, the magnetic attraction device 10 can automatically disengage due to power failure, at the moment, the weight box 9 falls to the lowest end under the action of gravity, and then the safety rope 12 is driven to rise to the top (namely, the device is opened, a passenger gets on the bus), so that the passenger can not get on or off the bus during power failure.

Further, a wireless receiver 17 is installed at the top end of the box body and used for receiving a control command sent by a remote controller, and an electric control cabinet 18 is arranged in the inner cavity of the box body 11 and used for installing electric equipment such as a main control board and the like. After the wireless receiver 17 receives the control command, the main control board executes the control command to control the lifting of the safety rope. The bottom end of the box body 11 is fixed on the ground. The wireless receiver 17, the electric control cabinet 18, the main control board and the like are all the existing devices, and are not described herein again.

Further, the bullet-resistant device 14 is installed between the two boxes 11, as shown in fig. 4-1 and 4-2, the bullet-resistant device 14 is of a cuboid structure, an accommodating groove which is longitudinal and penetrates from the left side to the right side of the bullet-resistant device 14 is formed in the middle of the cuboid structure, the plane where the accommodating groove is located is perpendicular to the ground, and the upper end of the accommodating groove is a V-shaped opening; the receiving groove divides the projectile blocking device 14 into a front-side housing and a rear-side housing.

At least one guide seat 19 is respectively arranged at the front side and the rear side above the accommodating groove, namely, at least one guide seat 19 is arranged at the upper end of the front side shell, and at least one guide seat 19 is arranged at the upper end of the rear side shell. Each guide seat 19 is a wedge-shaped block, and a wedge surface of the wedge-shaped block and a plane of the V-shaped opening at the upper end of the accommodating groove are located in the same plane, that is, two inclined planes of the V-shaped opening extend upwards. The middle part of the safety rope 12 can be conveniently guided into the V-shaped opening by the guide block 19, so that the safety rope 12 can smoothly enter the accommodating groove. Hinder bullet device 14 and set up between two boxes, when safety rope 12 descends, the middle part of safety rope 12 can get into and hinder the holding tank of bullet device in, and the V type opening of guide holder 19 and holding tank can play the guide effect that gets into the holding tank to safety rope 12 descends.

Because the middle of the safety line 12 is located in the receiving groove of the bullet-stopping device 14, the safety line is not deformed much when being collided. Therefore, after the safety rope descends to an intercepting state, the middle part of the safety rope is positioned in the accommodating groove of the bullet-resistant device 14, the bullet-resistant device 14 can prevent passengers from colliding with the safety rope to cause impact rebound of the rope and excessive deformation beyond the edge of the platform to cause the passengers to fall down or fall down the platform, and meanwhile, the passengers are prevented from being injured by the rebound of the safety rope.

Furthermore, infrared sensing devices 13 are respectively arranged on the left side and the right side of a front side shell of the bullet-resistant device 14, a display screen 15 and a voice player 20 are arranged on the front side surface of the front side shell, and a warning lamp 16 is arranged on the upper end surface of the front side shell. The infrared sensing device 13, the display screen 15 (which may be a liquid crystal display), the voice player 20 and the warning light 16 are all commercially available products.

The main control board receives the display command sent by the hotel suit system, displays the information such as the current carriage number, the sequence of the carriage number, the train number and the like on the display screen 15, replaces a traditional ground carriage number display device, and is convenient for updating the information at any time. And display screen 15 accords with passenger sight scope more, can guarantee that the passenger gets on the bus according to the information safety order that shows, promotes customer experience. The hotel uniform system is an existing system, information is displayed on a display screen according to the information of the hotel uniform system and can be realized by adopting the prior art, and the details are not repeated.

Moreover, the infrared sensing device 13 (which adopts a commercially available infrared correlation sensor) can assist the safety rope to judge whether an object approaches, when the passenger is in a waiting state, if the infrared sensing device 13 is blocked, the object approaches the safety rope, at this time, the voice player 20 of the bullet blocking device 14 can send out a voice alarm to prompt the passenger to leave the safety rope, and simultaneously, an alarm signal is output to the main control board, and the alarm lamp 16 is lighted in red. In practice, the warning light 16 may be set as: the green light is lighted at ordinary times, the yellow light is lighted when the safety rope rises, and the red light is lighted when the safety rope gives an alarm.

Infrared sensing devices 13 may be further installed at both sides of each case 11. The infrared sensing device 13 is a plurality of sets of emitters and receivers, the emitters and the receivers are respectively arranged on two sides of each box body, and one of the emitters and one of the receivers in each two adjacent box bodies emit infrared rays. These are prior art and will not be described further herein.

Under normal operating mode, before the passenger arrives at a station, all safety ropes 12 are all in the low level, prevent that the passenger from getting into the danger area, and after the train arrival stops steadily, the main control board sends out the order, and the safety rope 12 that corresponds the platform position risees. When the passengers are all boarding the car, and the car door is closed, the safety line 12 descends until the next train arrives.

The bullet-resistant device can also be independently used for the platform according to the requirement of the platform, namely, only the bullet-resistant device is used without a safety rope and box bodies on two sides. Because the infrared sensing devices are arranged on two sides of the bullet-resistant device 14, if a person approaches or wants to pass through the bullet-resistant device, the bullet-resistant device can give out a voice alarm and light a red light, and the bullet-resistant device can also play a role in interception.
