The base 19 may be a bending piece made of metal, one end of the base 19 is fixedly connected with the elevator guide rail, and the stepping motor 11 is fixed on the other end of the bending. The base 19 is provided with a through hole at one end fixed with the elevator guide rail, and the through hole can enable one end of the action pin 17 far away from the stepping motor 11 to extend out of the base 19. Further, two ends of the through hole of the base 19 are provided with an action switch 18 and a reset switch 110, and the action switch 18 and the reset switch 110 are symmetrically arranged at two sides of the action pin 17.
The rotating assembly comprises a rotating wheel 12 and a rotating arm 16 fixed on the motor shaft of the stepper motor 11. The rotating arm 16 is stacked on the rotating wheel 12, one end of the rotating arm 16 far away from the elevator guide rail is hinged with the rotating wheel 12 through a connecting shaft fixed with the elastic collar 14 for a shaft, and the other end of the rotating arm 16 is connected with the action pin 17 through a connecting shaft 15 and is fixed through the elastic collar 14 for a shaft.
The action pin 17 may be a metal piece made of metal, and grooves are staggered on two sides of the action pin 17, and the grooves respectively correspond to the action switch 18 and the reset switch 110.
When the automatic control mechanical prevention device is in a non-operating state, the reset switch 110 is triggered and the action switch 18 is turned off. When the mechanical stopping device is in a working state, the stepping motor 11 drives the rotating wheel 12 to rotate, and drives the rotating arm 16 to synchronously rotate. When the rotating arm 16 rotates, the rotating arm stretches forwards to push the action pin 17 to displace, so that the free end of the action pin 17 stretches out of the base 19; the action switch 18 is triggered and the reset switch 110 is closed.
The stopping device 2 consists of an elevator safety gear 26, a lifting arm 21, a torsion spring 23 and a linkage rod 24. The elevator safety tongs 26 are respectively arranged beside the two sliding rails of the elevator car and are fixed by the fixing seat 25. The safety gear 26 is provided with a limiting groove 28 for accommodating the lifting arm, and the limiting groove 28 can be a through groove inclined to the tightening side of the safety gear 26. The lifting arm 21 is arranged on the outer side of the elevator safety gear 26, and the lifting arm 21 passes through the limit groove 28 to be in sliding connection with the elevator safety gear 26. Further, the lifting arm 21 may be slidably connected to the elevator safety gear 26 through a sliding block extending into the limiting groove 28, and the sliding block is fixedly connected to the lifting arm 21 through a fixing pin. The lifting arms 21 are respectively arranged beside the two guide rails of the elevator, and the two lifting arms 21 are connected through a linkage rod 24 penetrating through fixing seats 25 at two ends of the elevator. The link lever 24 may be made of metal, and the link lever 24 fixes the lift arm 21 by the elastic pin 22. The two torsion springs 23 are respectively fixed at two ends of the linkage rod 24, one end of each torsion spring 23 is fixed on the linkage rod 24 by a bolt 27, and the other end is fixed on the fixing seat 25 by a perforation.
When the mechanical stopping device is in the non-working state, the lifting arm 21 is positioned at the bottom of the safety gear 26 due to the torsion force of the torsion spring 23. When the mechanical stopping device is in a working state, the lifting arm 21 is abutted against the extended action pin 17, and one end of the lifting arm 21 connected with the elevator safety tongs 26 slides upwards along the limit groove 28 to push the elevator safety tongs 26 to tighten and clamp the elevator guide rail.
According to the above-described embodiment, an implementation may be achieved: the stopping device 2 is fixed at the bottom of the elevator car, and the limiting device 1 is arranged at the bottom of the elevator guide rail. When the mechanical stopping device is in an operating state, the stepping motor 11 of the limiting device 1 rotates. When the rotating wheel 12 on the stepping motor 11 rotates 180 degrees, the belt rotating arm 16 pushes the operating pin 17 to move horizontally. The actuating pin 17 extends in the direction of the elevator car. During the descending of the elevator, the lifting arm 21 is abutted against the rotating arm 16. The two ends of the lifting arms 21 are driven by the linkage rod 24 at the same time, so that the lifting arms 21 rotate from the bottom of the safety tongs 27 to the top of the safety tongs 27, and the elevator safety tongs 27 clamp the elevator guide rail after being tightened, so that the elevator car stops.
In another embodiment the stopping appliance 2 is fixed to the top of the elevator car and the limit appliance 1 is mounted on top of the elevator guide rail. When the mechanical stopping device is in an operating state, the stepping motor 11 of the limiting device 1 rotates. When the rotating wheel 12 on the stepping motor 11 rotates 180 degrees, the belt rotating arm 16 pushes the operating pin 17 to move horizontally. The actuating pin 17 extends in the direction of the elevator car. During the upward movement of the elevator, the pulling arm 21 abuts against the rotating arm 16. The two ends of the lifting arms 21 are driven by the linkage rod 24 at the same time, so that the lifting arms 21 rotate from the bottom of the safety tongs 27 to the top of the safety tongs 27, and the elevator safety tongs 27 clamp the elevator guide rail after being tightened, so that the elevator car stops.
In another embodiment shown in fig. 10, the stepper motor 11 may be fixedly mounted to the top or bottom side of the hoistway by a bent piece. When the mechanical stopping means is in an operating state, the stepper motor 11 is rotated. When the rotating wheel 12 on the stepping motor 11 rotates 180 degrees, the belt rotating arm 16 pushes the operating pin 17 to move horizontally. The operating pin 17 extends in the direction of the elevator car, so that the pulling arm 21 abuts against the rotating arm 16. The two ends of the lifting arms 21 are driven by the linkage rod 24 at the same time, so that the lifting arms 21 rotate from the bottom of the safety tongs 27 to the top of the safety tongs 27, and the elevator safety tongs 27 clamp the elevator guide rail after being tightened, so that the elevator car stops.
