LIFING APPARATUS CAPABLE OF HORIZONTALITY CONTROL

摘要

PURPOSE: A lifting device capable of keeping the horizontal sate of an object is provided to precisely control the lifting height of an object because the reduction ratio of a worm unit and a worm wheel unit is high. CONSTITUTION: A lifting device(100) capable of keeping the horizontal sate of an object comprises two or more worm wheel units(110), a worm unit(120), and a housing(130). The worm wheel units are vertically moved along lifting rods(R1,R2). Gear teeth are formed on the outer surface of the worm wheel units. The worm unit is meshed with the gear teeth of the worm wheel units at a right angle to the lifting rods and is rotatably coupled to the inside the housing. The housing is touched with the bottom surface of an object and supports the object.
