AI Technical Summary
Existing manual and electric cage curtain doors pose safety hazards such as high labor intensity for workers, easy deformation of crossbars, difficulty in smooth mounting, and inability to interlock with the hoist.
The curtain door crossbar is replaced with a square steel crossbar and a smooth round steel door post, which are connected to the door post by internal cylindrical rollers at both ends. This reduces sliding friction and replaces it with rolling contact. Combined with a transmission mechanism and encoder, precise control is achieved.
It reduces wear and lifting resistance, improves operational stability and safety, and achieves interlocking control with the hoist.

[0018] The principles and characteristics of the application are described below in combination with the drawings, and the examples are only used for explaining the application and are not used for limiting the scope of the application.
[0019] As Figures 1-3 shown, an electric cage door device, comprising a door column 8 and a transmission mechanism installed inside a cage upper disc, two transmission chains 2 are arranged on the transmission mechanism, a plurality of curtain door cross bars 1 are arranged on the transmission chains 2, the door column 8 penetrates the end portion of the curtain door cross bar 1, and a cylindrical roller 6 is arranged in the end portion of the curtain door cross bar 1 and is in rolling connection with the two side surfaces of the door column 8. The transmission mechanism comprises a driving wheel, a driven wheel, a transmission shaft, a direct current motor and an encoder, which are all installed inside the cage upper disc; the transmission mechanism drives the curtain door cross bars 1 on the two transmission chains 2 to ascend and descend, the cylindrical roller 6 in the both end portions of the curtain door cross bar 1 is in rolling contact with the door column 8, the existing sliding friction is replaced with the rolling contact, the abrasion is effectively reduced, the ascending resistance is small and the operation is stable. After the cage is positioned and the locking is released, the direct current motor rotates to drive the driving wheel, the transmission shaft and the driven wheel to rotate; the transmission chain 2 moves from the bottom to the top in sequence to drive the plurality of curtain door cross bars 1 to ascend in sequence. The equipment feeds back the position and speed through the encoder, and the system accurately controls the electric cage door to open and close to the required position. When the door is closed, the motor reversely rotates to stop at the required position, the signal is fed back to the lifting system, the electric cage door is interlocked with the elevator, and the electric cage door cannot be actuated when the elevator is operated.
