AI Technical Summary
The existing elevator anti-fall device fails in the event of a power outage, which may cause the elevator personnel to be in a dangerous state. When the bottom floor falls due to insufficient buffer distance, it may cause the elevator to fall down but not stop, causing personnel injury.
An elevator anti-fall protection device is designed, including a capacity unit, a fall protection unit and a buffer unit. The capacity unit converts the kinetic energy of the car into electrical energy through a bidirectional generator and stores it in the energy storage speed detection box to ensure that power can still be supplied to the fall-proof unit during power outage. The anti-fall unit uses a servo motor, threaded rod and linkage block system to clamp the slide post to achieve safe stop of the car. The buffer unit utilizes giant hydraulic rods and hard springs to provide first and second stage cushioning to prevent damage caused by insufficient buffering when the elevator falls on the bottom floor.
The anti-fall protection device that can still operate normally in the event of power outage is realized to ensure the safety of elevator personnel. The multi-layer buffering system solves the problem of the elevator not stopping falling due to insufficient buffering when the bottom floor falls.

It has a car that runs between at least two vertical rigid guide rails or rails with an inclination angle of less than 15°. The size and structure of the car are convenient for passengers to enter and exit or load and unload goods.

[0039] Specific use of the present invention: The elevator anti-fall protection device of the present invention detects that the second gear 609 exceeds the specified speed when the energy storage speed detection box 608 detects that the car 5 is in a falling state.

Part of the electric energy generated by the two-way generator 605 is used for power supply inside the car 5, and the other part is stored in the energy storage speed detection box 608. The No. 2 gear 609 in the energy storage speed detection box 608 rotates due to the rotation of the No. 1 gear 604. The energy storage speed detection box 608 can detect the speed of the No. 2 gear 609. An elevator anti-fall protection device of the present invention may slow down the descending speed of the car 5 but will not stop it through the anti-fall unit 7 when it is at the bottom layer. At this time, when the car 5 falls to the lowest layer, the car 5 will press down the square rubber pad 814, and the square rubber pad 814 will play a part of the buffering force. Then the giant hydraulic rod 810 will unload part of the force and play a role of primary buffering. Then the micro hydraulic rod 815 ensures that the connecting plate 811 is in a balanced state when pressing down. The No. 1 linkage rod 806 and the No. 2 linkage rod 813 are rotated and pushed outward on the No. 1 functional block 801 and the connecting plate 811 respectively. The No. 1 linkage rod 806 and the No. 2 linkage rod 813 are rotated and connected on the connecting block 807, pushing the No. 1 push plate 808 outward until it is against the No. 2 push plate 809. The No. 2 push plate 809 compresses the hard spring 803 in the inner cavity of the No. 2 functional block 802 to play a secondary buffering role.
