Automatic lifting mechanism

Abstract

The invention provides an automatic lifting mechanism. The automatic lifting mechanism comprises a first-stage lifting device, wherein the first-stage lifting device can conduct lifting movement in avertical direction, and can be supported on a ceiling; a second-stage lifting device arranged on a frame conducts lifting movement in the vertical direction of the frame, and the upper end portion ofthe second-stage lifting device is connected with the first-stage lifting device through a sliding pair, so that the rigidity of second-stage lifting device is improved; a third-stage lifting device conducts synchronous lifting movement along with the second-stage lifting device; left and right arms arranged on the third-stage lifting device conduct synchronous lifting movement along with the third-stage lifting device, and conduct forward or backward telescopic movement in the vertical direction of the third-stage lifting device respectively; a fourth-stage lifting device conducts synchronoustelescopic movement and angle adjustment along with the left arm and/or the right arm, and conducts lifting movement in the vertical direction; and a translation device conducts synchronous telescopic movement and/or lifting movement along with the fourth-stage lifting device. The automatic lifting mechanism is high in precision, high in rigidity, high in carrying capacity and high in freedom degree, and multi-degree-freedom high-precision controllable movement in other directions is achieved at the same time.

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. ...

[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.
