Problems solved by technology

[0010] The purpose of the present invention is to provide a two-way screw type elevator drive mechanism, which can simultaneously solve the two problems of people being trapped in the elevator when the power failure or the screw shaft motor fails, and the speed of the elevator's downward movement is difficult to control.

Embodiment Construction

[0033] like image 3 As shown, it is a schematic diagram of an embodiment of the present invention. In the present invention, the upper end of the screw shaft 1 is locked above the bracket 2 with the screw shaft support seat 21, so that the screw shaft 1 is vertically suspended on the bracket 2;

[0034] The upper end of the screw shaft 1 is connected to a screw shaft motor 6, which is used to drive the screw shaft 1 to rotate; and the screw of the rotating shaft is a ball screw.

[0035] In addition, the screw shaft 1 is equipped with a nut 3, and the nut 3 and the screw shaft 1 are matched in a spiral manner. When the screw shaft 1 rotates and the nut 3 does not rotate, due to the gap between the screw shaft 1 and the nut 3 The relative spiral movement produces relative linear movement;

[0036] A connecting seat 4 is used to connect the car body 5 and the nut 3 of the elevator, so that the two are linked without linear displacement, and when the nut 3 rises, the car body 5...

Abstract

The present invention discloses a two-way screw-type elevator drive mechanism, which uses two motors, a screw shaft motor and a screw cap motor. Under normal use, the elevator cabin is driven by the screw shaft motor to move up and down; while under an abnormal condition, the cabin will move downwards driven by the screw cap motor. In the case of power failure or screw shaft motor failure, the elevator will be driven by the screw cap motor by using a tiny backup power supply to move downwards to the landing door position of the next floor or the lowest floor, so that passengers in the elevator cabin can easily open the cabin door and leave. The invention can prevent passengers being trapped in the elevator in the case of power failure or screw shaft motor failure, and also solves the problem that the mobile speed in elevator descending is difficult to control.

Description

technical field [0001] The invention relates to an elevator, especially a two-way screw type elevator driving mechanism. Background technique [0002] In the 21st century, the number of elderly senior citizens has increased rapidly, and it is very difficult for senior senior citizens to commute without elevator facilities. Therefore, elevator facilities will play a very helpful role in the home life of the elderly, now and in the future. [0003] The development of elevators has a history of more than 100 years. Looking back at the design of elevator transmission mechanisms over the past century, there are mainly four designs over the years: screw type, hydraulic type, cable type, and linear motor type. At present, the most common driving mode of the elevator is a cable-type elevator in which the cable drives the car body to move up and down. [0004] However, cable elevators are more suitable for carrying passengers and goods in buildings. For the current personal resident...
