Elevator provided with safety protection device

Abstract

The invention discloses an elevator provided with a safety protection device. A turnover assembly of the novel elevator comprises a rotating motor, a fourth rotating shaft, an arc-shaped gear, a first arc-shaped connecting rod, a fifth rotating shaft, a second arc-shaped connecting rod, a box door and a third gear, wherein the rotating motor is fixed to the outer wall of one side of a lift car in an embedded mode, the third gear is fixedly mounted at one end of an output shaft of the rotating motor, the box door is rotationally mounted on the outer wall of the bottom end of one side of the lift car through the fourth rotating shaft, and the arc-shaped gear is welded to the position, corresponding to the third gear, of the outer wall of one side of the box door. According to the novel elevator, speed limiting devices are symmetrically mounted at the two sides of a box body, so that the overall elevator has the advantages that a speed limiting rope which is mounted can prevent the lift car from swinging left and right, so that the box body is stabilized and balanced; and when the box body descends too fast, clamping strips in the speed limiting devices are clamped into grooves under the centrifugal effect, so that the box body stops descending rapidly, and the life safety of workers is guaranteed.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an elevator equipped with a safety protection device. Background technique [0002] Elevator refers to the permanent transportation equipment that serves several specific floors in the building, and its car runs on at least two rigid rails perpendicular to the horizontal plane or with an inclination angle of less than 15° from the plumb line. The elevator structure used in the existing construction Single, the safety and stability are greatly reduced in the harsh construction environment, and there is a certain gap between the existing elevator and the building when it is installed and designed. It is easier for workers to get stuck in such a gap if they do not pay attention. , Bring greater potential safety hazards to workers. The existing construction elevators do not have a deceleration device, and can only be controlled by the rotation speed of the electricity. If the motor...

The elevator structure used in the existing construction Single, the safety and stability are greatly reduced in the harsh construction environment, and there is a certain gap between the existing elevator and the building when it is installed and designed. It is easier for workers to get stuck in such a gap if they do not pay attention. , bring greater safety hazards to workers, the existing construction elevators do not have a deceleration device, can only rely on the rotation speed of the electricity to control the descending speed, if the motor fails, it will bring greater hidden dangers to workers' life safety
