A lifting device with right half-rotation and extension used by decoration workers to decorate the ceiling

Abstract

The invention discloses a right-side semi-rotation extension lifting device used by a decoration worker to decorate a ceiling. The structure comprises a chute vertical pole, arc plate supports, a lifting work bench, an auxiliary rotation groove, an exhibition platform folding frame, a truss rod, a lifting transmission arc groove and a shaft driving motor. There are two arc plate supports which arearranged on the lower left and right corners of the lifting work bench. In the invention, a roll shaft rod is used to be cooperated with a connection rack exhibition platform block, a Z-shaped rockerrotates and pulls a piston arc rod to turn left 90 degrees so that the piston arc rod links a composite liner groove frame to expand a quarter circle platform. And an arc-surface baffle plate stretches, expands and pastes an indoor round chamfer so as to form a round-surface embedded sealing structure. A worker can conveniently tread to install the ceiling, a condition that the worker loses footing because of a groove seam and falls down is avoided, side exhibition platform deformation adherence performance is good, and expanded support and reinforcing are increased. The work area of the lifting work bench is expanded and work efficiency is increased.

Description

technical field [0001] The invention relates to a right half-rotating and extending lifting device used by decoration workers to decorate ceilings, belonging to the field of decoration equipment. Background technique [0002] Decoration workers need a lifting device to lift the human body in the air to work on the ceiling, which saves the manpower for indoor ladder decoration. It is convenient for lifting and loading and loading materials, which saves time and effort for ceiling decoration. The working area is limited, and it is more cumbersome when encountering indoor corners. The shortcomings of the current technology that need to be optimized are: [0003] When working at indoor corners, workers need to get off the lifting platform and rotate the lifting device to fit the corner surface and then climb up the lifting platform. It is very tossing, and under the indoor structure with round chamfers, the quadrilateral device base will be in line with the arc surface Insuffic...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a right half-rotating and extending lifting device for decoration workers to decorate the ceiling, so as to solve the problem that workers need to get down from the lifting platform to rotate and place the lifting device when they are at indoor corners. It is very troublesome to fit the wall corner and then climb up the lifting platform, and under the indoor structure with round chamfers, the quadrilateral device base will not fit the arc surface enough, leaving a gap on the workbench. There is a risk of stepping on the air and falling in mobile work
