Problems solved by technology

[0005] In addition, for multi-screw-driven elevators, although the effective number of people in the car can be increased, as the use time becomes longer and the synchronization errors of each screw accumulate, the car will easily tilt, and at the same time, the corresponding screw drive device and screw will be aggravated. wear and tear

Abstract

The invention discloses a lifting device for an elevator car. The lifting device comprises a screw rod, a bearing base and a limiting top plate, wherein the elevator car is arranged between the bearing base and the limiting top plate, the bearing base is provided with a ball sleeve and a driving device used for driving the ball sleeve to rotate, and auxiliary supporting columns are arranged belowthe bearing base; the bearing base comprises a base, a bottom plate and an arc-shaped plate, wherein the arc-shaped plate is hinged to the bottom plate, the base is provided with a fixing groove, thebottom of the fixing groove is provided with through holes, and the auxiliary supporting columns pass through the through holes to temporarily support the bottom plate; and the driving device drives the ball sleeve to rotate, so that the bearing base is lifted along the screw rod, the bottom plate is gradually separated from the support of the auxiliary supporting columns, and the bottom plate andthe arc-shaped plate are pressed into the fixing groove through the elevator car under the guide of the arc-shaped plate. According to the lifting device, the elevator car is convenient and fast to install, and the elevator car can be easily replaced in the later period.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to a lifting device for an elevator car. Background technique [0002] Compared with traction elevators, screw elevators are safer. From the perspective of the working principle of the screw elevator, the unique occlusal structure of the screw elevator can ensure that it will never fall down. Moreover, the structure is simple, there is no counterweight, it takes up less space, and the space utilization rate is high, which is very suitable for the home environment where every inch of land is expensive. [0003] On the other hand, screw elevators generally drive devices through a screw and a thread corresponding to the screw, such as a large nut with a thrust bearing or a threaded sleeve with balls. However, in the existing screw-type car, it is generally necessary to install the threaded driving device first, and then build the car on the threaded driving device, which is complic...
