The utility model provides an
elevator door protection device which comprises an
elevator car, a shell penetrates through the top between two
elevator car
doors of the elevator car, the shell is fixedly installed on the elevator car, a 3D light curtain protection device is arranged in the shell, a connecting rod is fixedly arranged on one side of the 3D light curtain protection device, and a sliding groove matched with the connecting rod is formed in the middle of one side of the shell. A limiting plate is fixedly arranged on one side of the connecting rod, a limiting
assembly is arranged between the limiting plate and the shell, an auxiliary mechanism used for driving the limiting
assembly is arranged at the bottom end of the limiting plate, and a
protection mechanism is arranged on the side, facing the shell, of the limiting plate. By arranging the shell, the 3D light curtain protection device can be installed on the lift car, under the action of the 3D light curtain protection device, when passengers get in and out of the lift car, the 3D light curtain protection device can output signals to enable the motor state of the lift
car door to be kept as long as the passengers are in the induction area of the 3D light curtain protection device, then the door is opened in place firstly, and then the door is closed in place; through the arrangement, not only is the collision injury of the
