Detailed Description
The invention is further described with reference to the accompanying drawings and the detailed description.
As shown in fig. 1, 2, 3 and 4, a screw-driven elevator door apparatus, which is installed on the top of an elevator car, includes a door motor driving device, a door motor connecting device and an elevator car door 1; the door machine driving device comprises a driving motor 2 and a driving screw rod 3, the door machine connecting device is arranged on the driving screw rod 3, and the elevator car door 1 is arranged on the door machine connecting device; the door machine driving device drives the door machine connecting device to open and close the elevator car door 1.
The door connecting device comprises a sleeve 4 and a connecting rod 5, the sleeve 4 is installed on the driving screw rod 3, the connecting rod 5 is fixed on the sleeve 4, and the elevator car door 1 is connected to the connecting rod 5. The driving device of the door machine can make the sleeve 4 of the door machine connecting device do reciprocating linear motion, so that the opening and closing of the car door are realized, the driving mode is simple, and the elevator car door 1 is more stable in the opening and closing processes.
The connecting rod 5 is provided with a roller 6, and a track 7 matched with the roller 6 is arranged below the connecting rod 5.
