A kind of anti-fall buffer mechanism of intelligent elevator

Abstract

The utility model is applicable to the technical field of elevators, and provides an anti-fall buffer mechanism of an intelligent elevator, comprising an elevator box, wherein the lower surface of the elevator box is fixedly connected with a speed sensor, and the inner wall of the elevator box is fixedly connected with a controller. The utility model detects the running speed of the elevator box through the speed sensor. When the elevator box falls, the speed sensor detects that the running speed of the elevator box exceeds a set value, and the speed sensor sends a signal to the controller. The controller receives the signal of the speed sensor, and the controller controls the operation of an electric hydraulic rod. Through the extension of the telescopic end of the electric hydraulic rod, the support rod is expanded to the surroundings, so that the abutment plate contacts the inner wall of the elevator shaft, thereby increasing the friction between the elevator box and the elevator shaft, slowing down the falling speed of the elevator box, and absorbing and weakening the impact force on the elevator box through the first damper and the first spring, so as to provide buffer protection for passengers in the elevator box when the elevator box falls.

Description

Technical Field

[0001] The utility model belongs to the technical field of elevators, and in particular relates to an anti-falling buffer mechanism of an intelligent elevator. Background Art

[0002] Elevator refers to a permanent transportation device that serves several specific floors in a building, and its car runs on at least two rows of rigid tracks that are perpendicular to the horizontal plane or inclined at an angle of less than 15° to the plumb line. At the end of the 20th century, elevators used permanent magnet synchronous traction machines as power. It greatly reduced the area occupied by the machine room, and has the advantages of low energy consumption, energy saving and high efficiency, and fast lifting speed, which greatly promoted the development of real estate towards super-high-rise buildings.

[0003] After searching, the Chinese patent application number is: 202110000070.7, which discloses an elevator with an anti-fall buffer structure, including a car, a support plate fixedly connected to the bottom end of the car, a first fixed plate fixedly connected to one side of the car, and a second fixed plate fixedly connected to the side of the car away from the first fixed plate. Two fixed grooves are provided in the first fixed plate, and the two fixed grooves are fixedly connected to the connecting groove. A fixing mechanism is installed in each of the two fixed grooves, and a baffle is installed on the side close to each other of the two fixing mechanisms, and a pushing mechanism is installed on the rear of the side close to each other of the two fixing mechanisms. The second turning handle drives the connecting rod to rotate, the connecting rod drives the seventh bevel gear to rotate, the seventh bevel gear drives the eighth bevel gear to rotate, and drives the third threaded rod to rotate, so that the third threaded rod drives the square plate to move to the side away from the square groove, thereby separating the square plate from the square groove, and then facilitating the use of the pull handle, so that the pull handle plays a role in assisting the support of the human body. In the prior art, most elevators adopt an independent buffer structure, which cannot solve the problem of early deceleration before falling to the bottom. Utility Model Content

[0009] Preferably, a wear-resistant rubber layer is fixedly connected to the outer wall of the abutment plate.

[0010] Compared with the prior art, the embodiments of the present application have the following beneficial effects:

[0011] The speed sensor is used to detect the running speed of the elevator car. When the elevator car falls, the speed sensor detects that the running speed of the elevator car exceeds the set value. The speed sensor sends a signal to the controller. The controller receives the signal from the speed sensor and controls the operation of the electric hydraulic rod. The telescopic end of the electric hydraulic rod is extended to expand the support rod to the surroundings, so that the abutment plate contacts the inner wall of the elevator shaft, thereby increasing the friction between the elevator car and the elevator shaft and slowing down the falling speed of the elevator car.
