Problems solved by technology

[0002] At present, the elevator car door safety touch panel is installed in parallel with the car door. By pressing the safety touch panel, the closed car door can be reopened to ensure the personal safety of passengers when they enter and exit; In the case of failure or abnormal door closing signal, the elevator may not be able to brake the elevator when the door is opened on the leveling floor, and the elevator will move abnormally, posing a threat to the passengers entering and leaving the elevator. Similar elevator accidents have also occurred during the actual use of the elevator. The safety of the elevator is low and needs to be further improved

Embodiment 1

[0026] Such as Figure 1 to Figure 4 As shown, a safety elevator with a door-opening abnormal protection function includes a car 1, a safety touch panel 4 is provided on the car door 2 of the car 1; a limit plate 5 is movable on the safety touch panel 4, and the safety There is a vertical axis of rotation between the touch plate 4 and the limiting plate 5, and the limiting plate 5 is connected with the rotation control device and can rotate around the rotation axis under the action of the rotation control device.

[0027] Wherein, the upper end of the safety touch plate 4 and the limit plate 5 is provided with an upper shaft 6, the lower end of the safety touch plate 4 and the limit plate 5 is provided with a lower shaft 7, and the upper end of the safety touch plate 4 and the limit plate 5 passes through the upper shaft. 6. The lower rotating shaft 7 is movably connected; on both sides of the safety touch plate 4 and the limit plate 5, there is a gap 9 between the upper end a...

Embodiment 2

[0032] Such as Figure 4 As shown, in the present embodiment, there are two car doors 2 on the car 1, and the safety contact plates 4 of the two car doors 2 are provided with a limit plate 5, and the two limit plates 5 are relatively arranged; Among the respective rotation axes of the positioning plates 5, the first rotation axis is biased toward the side of the car door 2, and the second rotation axis is away from the side of the car door 2; when the car door 2 is closed, the two limiting plates 5 are stacked, And the first limiting plate 5 is located on the outer side, and the second limiting plate 5 is located on the inner side;

Embodiment 3

[0034] Such as Figure 5 to Figure 7 As shown, the rotation control device is a return spring, a connecting rod 10 and a guide plate 11, the return spring is installed between the safety contact plate 4 and the limit plate 5, the connecting rod 10 is fixedly connected to the rotation axis of the limit plate 5, and the connecting rod The upper end of 10 is provided with roller 12, and guide plate 11 is arc-shaped, and the position of this roller 12 adapts with arc-shaped guide plate 11.

[0035] In this embodiment, when the elevator is in normal operation, if the car door 2 is closed, the roller 12 slides on the guide plate 11, and under the action of the guide plate 11, the connecting rod 10 drives the limit plate 5 to rotate and makes the limit plate 5 and the safety plate 5 rotate. The touch plate 4 is parallel, and when the elevator car door 2 and the hall door 3 are opened or after they are opened, the limiting plate 5 rotates under the effect of the back-moving spring and...

Abstract

The invention discloses a safe elevator with an abnormal door opening protecting function and a safe control method thereof. The elevator comprises a cage, wherein a safe contact plate is arranged on a cage door of the cage, a limiting plate is movably arranged on the safe contact plate, a vertical rotating axial line is arranged between the safe contact plate and the limiting plate, and the limiting plate is connected with a rotating and controlling device and can rotate around the rotating axial line under the function of the rotating and controlling device. When an elevator opens the door in a level surface and works in an abnormal mode, the invention has protecting function for personnel in the elevator and has high safety.

Description

technical field [0001] The invention relates to the field of elevators, in particular to a safety elevator with a door-opening abnormality protection function and a safety control method thereof.
