Abstract

Disclosed is an elevator safety door. The elevator safety door comprises pedal devices and a controller. Each pedal device comprises a pedal, an oscillating bar, an oscillating bar base, compression springs and an electromagnetic bolt. Each pedal is mounted on a floor in front of an elevator gate. The compression springs are arranged between the pedals and the floors, the oscillating bars are arranged between the pedals and the floors, and the middles of the oscillating bars are hinged to the oscillating bar bases. One end of each oscillating bar is connected with the corresponding electromagnetic bolt, the other end of the corresponding oscillating bar is hinged to a drive rod, the drive rods and the pedals are hinged, and the oscillating bar bases and the floors are fixedly connected. Elevator outer doors are provided with bolt holes, and the electromagnetic bolts are located below the bolt holes. When people stand on the pedals, lock bolts of the electromagnetic bolts are driven by the pedals and the oscillating bars to be inserted in the bolt holes of the elevator outer doors, the elevator outer doors cannot be opened, and thus people can be prevented from falling into an elevator car. When the elevator car travels to the elevator outer doors of the corresponding floor, the controller is used for controlling the lock bolts of the electromagnetic bolts to unlock, and accordingly the elevator outer doors can be opened.

Accompanying drawing explanation
Fig. 1 is the structural representation of elevator safety door.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further detailed:
The structural representation of the elevator safety door shown in Fig. 1, elevator safety door is provided with device with pedal 1 and controller 7, and device with pedal 1 includes pedal 2, fork 3, swing rod 4, Compress Spring 5 and electromagnetic bolt 6; Pedal 2 is installed on the floor 9 before elevator doorway 8, Compress Spring 5 is located between pedal 2 and floor 9, fork 3 is located between pedal 2 and floor 9, middle part and the swing rod 4 of fork 3 are hinged, one end of fork 3 is connected with electromagnetic bolt 6, the other end and the drive spindle 10 of fork 3 are hinged, and drive spindle 10 is hinged with pedal 2, and swing rod 4 is fixedly connected with floor 9; Elevator external door 11 is provided with locking bolt hole 12, and electromagnetic bolt 6 is positioned at the below in locking bolt hole 12; Controller 7 is provided with sensor 13, and sensor 13 is installed on the terraced railway carriage or compartment passage 20 below elevator external door 11, and cage 14 is provided with inductive head 15, and inductive head 15 is positioned at below cage inside door 21; Floor 9 before elevator doorway 8 is provided with groove 17, and groove 17 is provided with guide groove 18, and pedal 2 is provided with guide rail 19, and guide rail 19 is connected with guide groove 18 is dynamic.The aperture in the locking bolt hole 12 of elevator external door 11 is greater than the external diameter of the locking bolt 16 of electromagnetic bolt 6, to ensure that locking bolt 16 can be inserted in locking bolt hole 12.
The principle of work of elevator safety door is: when cage 14 does not drive to the position of this elevator external door 11, when people stands in pedal 2, utilize pedal 2 to drive fork 3 to swing, utilize fork 3 to drive the locking bolt 16 of electromagnetic bolt 6 to insert in the locking bolt hole 12 of elevator external door 11, elevator external door 11 can not be opened; When cage 14 drives to elevator external door 11 position of this floor, the locking bolt 16 utilizing controller 7 to control electromagnetic bolt 6 is retracted, and locking bolt 16 exits locking bolt hole 12, and elevator external door 11 can be opened; After cage 14 leaves elevator external door 11 position of this floor, elevator external door 11 is closed, and locking bolt 16 reset that controller 4 controls electromagnetic bolt 6 is stretched out; There is people again when entering pedal 2, repeating said process, so constantly circulation.
The principle of work of elevator safety door is specifically: during use, when the cage 14 of elevator does not drive to 8 position, elevator doorway of elevator, people enters into after the pedal 2 before elevator doorway 8, pedal 2 reduces under the Action of Gravity Field of human body, pedal 2 presses one end of fork 3 to lower swing by drive spindle 10, the other end of fork 3 is moved up, the locking bolt 16 of electromagnetic bolt 6 is made to insert in the locking bolt hole 12 of elevator external door 11, the locking bolt 16 of electromagnetic bolt 6 is utilized to pin elevator external door 11, elevator external door 11 can not be opened, prevent elevator external door 11 from surprisingly opening, the people on elevator doorway 8 is caused to fall in terraced railway carriage or compartment passage 20, when cage 14 drives to 8 position, elevator doorway, the inductive head 15 of cage 14 is close to the sensor 13 being installed on position, elevator doorway 8, sensor 13 by its Signal transmissions to controller 7, the locking bolt 16 that controller 7 controls electromagnetic bolt 6 is retracted, locking bolt 16 is made to leave locking bolt hole 12, elevator external door 11 is unlocked, elevator external door 11 can be opened, the people standing in pedal 2 leaves after pedal 2 enters cage 14, and pedal 2 rises reset under the effect at Compress Spring 5, after elevator external door 11 opens closedown again and cage 14 traveling leaves position, elevator doorway 8, sensor 13 leaves the position of inductive head 15, and sensor 13 is by its Signal transmissions to controller 7, and the locking bolt 16 that controller 7 controls electromagnetic bolt 6 stretches out reset, when there being people to stand in pedal 2 again, pedal 2 drives electromagnetic bolt 6 to rise by fork 3, and the locking bolt 16 of electromagnetic bolt 6 reinserts in the locking bolt hole 11 of elevator external door 11, and elevator external door 11 can not be opened, so constantly circulation.
The initial condition of electromagnetic bolt 6 is: elevator external door 11 is positioned at the position of closedown, and when the inductive head 15 of cage 14 is not close to sensor 13 below elevator external door 11, the locking bolt 16 of electromagnetic bolt 6 is the state of stretching out; Electromagnetic bolt 6 is not energized, and the locking bolt 16 of electromagnetic bolt 6 stretches out under the elastic force effect of its spring; When the inductive head 15 of cage 14 is close to sensor 13 below elevator external door 11, electromagnetic bolt 6 is energized, and the elastic force that the locking bolt 16 of electromagnetic bolt 6 overcomes spring under the effect of electromagnetic force is retracted.
Or, the initial condition of electromagnetic bolt 6 is: elevator external door 11 is positioned at the position of closedown, when the inductive head 15 of cage 14 is not close to sensor 13 below elevator external door 11, the locking bolt 16 of electromagnetic bolt 6 is the state of stretching out, electromagnetic bolt 6 is energized, and the elastic force that the locking bolt 16 of electromagnetic bolt 6 overcomes its spring under the effect of electromagnetic force stretches out; When the inductive head 15 of cage 14 is close to sensor 13 below elevator external door 11, electromagnetic bolt 6 power-off, the locking bolt 16 of electromagnetic bolt 6 is retracted under the elastic force effect of its spring.
As pedal 2 nobody, pedal 2 resets under the elastic force effect of Compress Spring 5, and pedal 2 drives fork 3 to reset, and fork 3 drives electromagnetic bolt 6 to move down, and makes the locking bolt 16 of electromagnetic bolt 6 be positioned at the position leaving locking bolt hole 12; When cage 14 drives to 8 position, elevator doorway, the inductive head 15 of cage 14 is close to the sensor 13 being installed on position, elevator doorway 8, and sensor 13 is by its Signal transmissions to controller 7, and the locking bolt 16 that controller 7 controls electromagnetic bolt 6 is retracted; Electromagnetic bolt 6 does not affect the normal operation of elevator.
During in order to ensure that terraced railway carriage or compartment inside door 21 is raised to aligning elevator external door 11 position, elevator external door 11 can be opened, and when the locking bolt 16 of electromagnetic bolt 6 is retracted, the upper surface of locking bolt 16 is lower than the lower surface of elevator external door 11, blocks elevator external door 11 after avoiding locking bolt 16 to retract; When cage 14 drives to elevator external door 11 position, inductive head 15 proximity transducer 13 of cage 14, the aligning ladder railway carriage or compartment inside door 21 of elevator external door 11.
