Detailed Description
The technical solution of the present invention will be described in detail by the following specific examples.
As shown in fig. 1 to 6, the anti-pinch elevator door system includes a door panel 2, a door operator 3, and an anti-pinch protection device, and the door panel 2 is hung on the door operator 3 and slides in a sill slide of the lower part. The left side and the right side of the door panel are symmetrically provided with door vertical frames 1, and a movable contact frame 5 is arranged between the door panel 2 and the door vertical frame 1 on each side. The anti-pinch protection device comprises a door vertical frame 1, a movable contact frame 5 and a microswitch 4. Door stile 1 is including the first limit of bending 11, the second limit of bending 12, the third limit of bending 13 and the fourth limit of bending 14 that connect gradually, leaves the opening between first limit of bending 11 and the fourth limit of bending 14, forms semi-enclosed installation cavity, and micro-gap switch 4 fixed mounting is in the installation cavity, and the fourth limit of bending 14 is bent towards the cavity outside and is formed backstop board 15. The movable contact frame 5 has a frame-shaped contact plate body 51, and the contact plate body 51 is of a hidden design and does not protrude into a space formed by the door standing frame 1 and the door panel. The touch plate body 51 is bent towards the outside of the frame to form a linkage wall plate 52, and the linkage wall plate 52 penetrates through the fourth bent edge 14 to be in transmission connection with the micro switch 4 through the switch beating plate 8, the roller and the transmission plate 7. The terminal vertical fixation of linkage wallboard 52 has switch beater 8, and the installation intracavity of door stile is fixed with the switch fixed plate, and it has driving plate 7 to articulate on the switch fixed plate, and micro-gap switch 4 installs the hinged end at driving plate 7, and the gyro wheel is installed to the other end of driving plate 7, and switch beater 8 presses on the gyro wheel. A composite spring 6 is connected between the linkage wall plate 52 and the door vertical frame 1, a hinge 9 is arranged between the linkage wall plate 52 and the fourth bending edge 14, a movable gap is formed between the touch plate body 51 and the stop plate 15, a gap is formed between the stop plate 15 and the door plate 2, and the movable contact frame 5 can rotate on the door vertical frame 1. According to the use requirement, a plurality of movable contact frames are distributed at intervals along the height direction of the door vertical frame.
The microswitch and the door opener are in signal connection with the elevator main control board, when a hand is inserted into a gap between the door plate and the door upright frame, the movable contact frame is driven to rotate through the contact plate body, and the linkage wall plate triggers the microswitch through the switch beating plate. Microswitches's signal transmission gives the anti-pinch safety module of elevator main control board, and elevator hauler stop operation, simultaneously, the elevator main control board sends the stall signal to the door operator, and the elevator door operator stops the action, and the elevator door plant stops moving to avoided the passenger to point to be pressed from both sides by the clearance between door plant and the door frame and hindered, after the passenger hand leaves the elevator door plant, the touch panel body resets under reset spring effect, and elevator door system resumes normally, and the elevator resumes normal operating. The anti-pinch safety module of the elevator main control board is provided with an anti-tamper function, and the elevator cannot normally run due to the fact that someone maliciously touches the touch panel body to trigger the micro switch to act. Generally, an elevator door system is composed of multiple layers (not less than 2 layers), the anti-pinch safety protection device only plays a role when a door corresponding to an elevator stopping layer is opened, and the normal operation of the elevator cannot be influenced by actions of the anti-pinch safety protection devices on other layers at any time; the anti-pinch safety protection device of the car door only plays a role when the elevator stops at a floor and opens the car door, and the anti-pinch safety protection device does not influence normal operation of the elevator at other times.
