Lifting device controlled by screw rod step motors

Abstract

The invention discloses a lifting device controlled by screw rod step motors. The lifting device is characterized in that the bottom of a first vertical rod is connected with a first roller through a first pin shaft; the bottom of a second vertical rod is connected with a second roller through a second pin shaft; a sliding groove and a straight groove are formed in each of the first vertical rod and the second vertical rod; a heavy rod is put in the sliding grooves in the vertical rods on two sides; a first threaded rod is arranged on a first screw rod step motor; a first spiral block is arranged on the first threaded rod; a first iron block is welded at the top end of the first threaded rod; a second threaded rod is arranged on a second screw rod step motor, a second spiral block is arranged on the second threaded rod; a second iron block is welded at the top end of the second threaded rod; one end of a supporting frame is connected with the spiral blocks through the straight grooves, and the other end of the supporting frame is connected with the heavy rod. The lifting device is novel in structure and reasonable in design, an elevator can be quickly started and stopped and can perform a quick lifting function through the screw rod step motors; with the arrangement of the rollers, people can move the lifting device conveniently.

Description

technical field [0001] The invention relates to the field of lifting and lowering of heavy objects, in particular to a lifting device controlled by a screw rod stepping motor. Background technique [0002] With the continuous development of industry, people have more and more needs for the convenience of heavy lifting and landing, and the current heavy lifting and landing are mostly driven by electric motors, but the current electric motors have many shortcomings, and cannot achieve fast start and stop , and the forward and reverse rotation of the motor cannot be realized. The current ordinary motor can only run in one direction when it is used. If you want to change the direction, you need to reverse the wires to realize the reverse rotation. During the rotation process, it will often start and stop suddenly, which will cause the motor to burn out. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior art and ...
