an automatic lifting mechanism

Abstract

The present invention provides an automatic lifting mechanism, comprising: a first-level lifting device capable of lifting and lowering along the vertical direction, and capable of propping up on the ceiling; a second-level lifting device arranged on the frame, Lifting movement, and its upper end is connected with the first-level lifting device through a sliding pair to improve its own rigidity; the third-level lifting device performs synchronous lifting movement with the second-level lifting device; the left 1. The right arm moves up and down synchronously with the third-level lifting device, and respectively performs forward and backward telescopic movements along the vertical direction of the third-level lifting device; the fourth-level lifting device performs synchronous telescopic movement with the left arm and / or right arm Movement and angle adjustment, lifting movement along the vertical direction; lateral movement device performs synchronous telescopic movement and / or lifting movement with the fourth-level lifting device. The invention has high precision, high rigidity, large bearing capacity and high degree of freedom, and simultaneously realizes multi-degree-of-freedom and high-precision controllable motion in other directions.

Description

technical field [0001] The invention relates to the field of automatic lifting and lowering of loads, in particular to an automatic lifting mechanism for heavy loads that is mainly used indoors from the ground to the full height of the ceiling. Background technique [0002] At present, there are many mechanisms that can be used for indoor lifting, but basically they can only achieve a partial height increase, and cannot achieve the full height increase of the indoor net height. While the object is lifted in the vertical direction, there is no high-precision controllable movement of other degrees of freedom. In addition, when the load of the existing lifting mechanism is large, the lifting mechanism itself has a large deformation, and the straightness of the trajectory during the lifting process cannot be guaranteed. Contents of the invention [0003] Aiming at the defects in the prior art, the object of the present invention is to provide an automatic lifting mechanism. ...

Problems solved by technology

[0002] At present, there are many mechanisms that can be used for indoor lifting, but basically they can only achieve a partial height increase, and cannot achieve the full height increase of the indoor net height. While the object is lifted in the vertical direction, there is no high-precision controllable movement of other degrees of freedom

In addition, when the existing lifting mechanism has a large load, the lifting mechanism itself has a large deformation, which cannot guarantee the straightness of the trajectory during the lifting process.
