[0019] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.
[0020] like Figure 1-3 As shown, a passenger protection device for an overhead passenger device comprises a fixed rod 1 and a movable rod 2.
[0021] The fixed rod 1 and the movable rod 2 are respectively arranged on both sides of the steel wire rope of the boarding area of the overhead passenger device; the fixed rod 1 and the movable rod 2 are parallel to the steel wire rope 3 of the boarding area; the fixed rod 1 is fixed to the side of the hanging chair of the overhead passenger device away from the steel wire rope 3, wherein the fixed rod 1 can be fixed to the rope support wheel seat 4 of the overhead passenger device, and the fixed rod 1 can prevent the passengers from hanging the hanging chair on the steel wire rope 3 in the reverse direction;
[0022] A lifting device is provided above the movable rod 2; the lifting device drives the movable rod 2 to move up and down. When the movable rod 2 is raised, the passengers can hang the hanging chair on the steel wire rope 3 and move on the hanging chair. When the movable rod 2 is lowered, it is parallel to the steel wire rope 3, so that the passengers cannot hang the hanging chair on the steel wire rope 3, thereby limiting the riding state and ensuring the distance between passengers.
[0023] The boarding area of the overhead passenger device is provided with two rope-supporting wheel seats 4, wherein the rope-supporting wheel seats 4 are equipped with rope-supporting wheels and rope-pressing wheels, the steel wire rope 3 is supported by the rope-supporting wheels, and the steel wire rope 3 is compressed by the rope-pressing wheels, and the two rope-supporting wheel seats 4 make the steel wire rope 3 horizontal, making it convenient for passengers to get on the vehicle; the fixed rod 1 and the movable rod 2 are between the two rope-supporting wheel seats 4.
[0024] The lifting device includes two cylinders 5, and a crossbeam 6 is provided between the two rope-supporting wheel seats 4; the two cylinders 5 are fixed below the crossbeam 6, wherein the two cylinders 5 are controlled by a two-position five-way pneumatic valve, so that the piston rods of the two cylinders 5 can be conveniently lowered at the same time; the piston rods of the two cylinders 5 are both arranged downward and are respectively connected to the two ends of the movable rod 2, so that the movable rod 2 can be conveniently driven to move up and down through the two cylinders 5.
[0025] In this embodiment, a Hall sensor is installed on one side of the boarding area of the overhead passenger device; the Hall sensor is electrically connected to the PLC controller, wherein the Hall sensor can be installed on the rope support wheel seat 4. When the hanging chair moves to the side of the Hall sensor along with the wire rope 3, the Hall sensor detects the hanging chair and sends a signal to the PLC controller. The PLC controller is electrically connected to the pneumatic valve, and the pneumatic valve is controlled by the PLC controller. The piston rods of the two cylinders 5 are extended, causing the movable rod 2 to drop, thereby blocking passengers from getting on the vehicle.
[0026] In this embodiment, an audible and visual alarm is installed on one side of the boarding area of the overhead passenger device; the audible and visual alarm is electrically connected to the PLC controller. After the PLC controller receives the signal from the Hall sensor, it simultaneously sends a signal to the audible and visual alarm. The audible and visual alarm emits a red light signal and voice to facilitate passengers to identify the boarding distance.
[0027] The utility model uses a method as follows: when passengers queue up to take a ride, the passengers take a hanging chair and enter the boarding area. After a passenger hangs the hanging chair on the steel wire rope 3, he sits on the hanging chair to ride. When the hanging chair moves to one side of the Hall sensor with the steel wire rope 3, the Hall sensor detects the hanging chair and sends a signal to the PLC controller. The PLC controller controls the pneumatic valve, and the piston rods of the two cylinders 5 extend to make the movable rod 2 drop. At the same time, the sound and light alarm sends a red light signal and a voice to prevent the next passenger from getting on the bus. After the movable rod 2 drops, the fixed rod 1 is used to mechanically restrict the steel wire rope 3 at the boarding point, so that the hanging chair cannot be hung on the steel wire rope 3. After the delay time is up, wherein the delay time = the passenger spacing ÷ the operating speed of the overhead passenger device, the PLC controller sends a signal to the pneumatic valve and the sound and light alarm again, the cylinder 5 retracts, the movable rod 2 rises, and at the same time the sound and light alarm sends a green light signal and a voice, and the next passenger can get on the bus.
