Problems solved by technology
However, this electric push scissor lift uses a motor to drive an electric push rod to move, but the connection between the electric push rod and the motor requires a more complicated transmission mechanism, which does not meet the actual work requirements; and if the two electric push rods do not move at the same time or One of them fails and stops working, which will cause the entire working platform to tilt, and the safety of the work will be affected.

The invention discloses an electric gear-rack driven scissor lift. The electric gear-rack driven scissor lift is characterized by comprising an upper-layer platform, a third-stage guide wheel, a rack, a gear, a middle-layer platform, a lower-layer platform, a second-stage guide wheel, a first-stage guide wheel, a first-stage fixed scissor arm, a first-stage movable scissor arm, a second-stage fixed scissor arm, a second-stage movable scissor arm, and a motor. The lift also comprises a motor control system that comprises a controller, a driver, a proximity switch, and a motor encoder. The lift does not need support from a hydraulic system, thereby avoiding leakage and pollution of an oil liquid and preventing potential safety hazards in use in such places as a workshop where electric sparks may be generated easily; and the safety of use of the machine is improved. The lift is relatively simple in structure, and free from oil contamination, and is able to satisfy accurate location of a lifting platform.
Description
technical field [0001] The invention relates to the field of electric lifting mechanical equipment, in particular to an electric rack and pinion push scissor lift. Background technique [0002] Scissor lift is a kind of lifting equipment used to lift people or goods to a certain height. It has the characteristics of easy operation and stable operation. It is widely used in aerospace, transportation, metallurgy, automobile manufacturing and other fields. Scissor lifts generally use hydraulic drive, and hydraulic drive requires a relatively complex hydraulic system to support, and the structure is relatively complicated; at the same time, the hydraulic system will inevitably produce oil leakage, causing oil pollution, and easy to generate electric sparks There are potential safety hazards in workshops and other places. In addition, the hydraulic drive cannot realize the height positioning and precise control of the lifting platform, and there is a large error in the accuracy ...
