Automatic leveling electro-hydraulic control system of two-column lifter

Abstract

The invention discloses an automatic leveling electro-hydraulic control system of a two-column lifter. The automatic leveling electro-hydraulic control system of the two-column lifter comprises a mainoil cylinder sliding table side upright post and an auxiliary oil cylinder sliding table side upright post, wherein a main oil cylinder sliding table laser receiver is arranged on a main oil cylindersliding table; an auxiliary oil cylinder sliding table laser emitter is arranged on an auxiliary oil cylinder sliding table; an oil immersion electronic control hydraulic station assembly is fixed tothe outer side of the main oil cylinder sliding table side upright post; a hydraulic station oil tank, an oil supplementing electromagnetic valve, an oil return exhaust electromagnetic valve, a throttling flow and pressure regulating valve and an electric control distribution box are arranged in a hydraulic station mounting aluminum substrate; the electric control distribution box is internally provided with a PLC, an ascending button, a descending button, a falling lock control button, a power conversion switch, an upper indicating LED lamp and a lower indicating LED lamp; and the ascendingbutton, the descending button, the falling lock control button, the power conversion switch, the upper indicating LED lamp and the lower indicating LED lamp are connected with the PLC. According to the automatic leveling electro-hydraulic control system of the two-column lifter, the arrangement is reasonable, the automatic leveling operation of the main oil cylinder sliding table and the auxiliaryoil cylinder sliding table can be realized, the use safety is improved, the maintenance and maintenance cost is reduced, the applicability is high, and the practicability is good.

Description

technical field [0001] The invention belongs to the technical field of two-column lifts, and in particular relates to an electric-hydraulic control system for automatic leveling of two-column lifts. Background technique [0002] It is known that a vehicle two-column lift uses a laser sensor to automatically adjust the oil-immersed power unit of the two-column lift to be of equal height on both sides of the slide. It is mainly to provide reliable control of the rise and fall of the two-post lift, and ensure that the lift can operate the lift and fall functions of the inspected vehicle safely, reliably and conveniently within the rated range. And with some lift installation, testing and leveling work. Its oil-immersed power unit contains electrical hydraulic control systems such as transfer switches, buttons, switching power supplies, PLCs, hydraulic stations, and solenoid valves. The main power supply of the oil-immersed power unit adopts AC ~ 220V / 1PH or ~ 380V / 3PH, and th...

AI Technical Summary

Problems solved by technology

[0008] The traditional electrical and hydraulic control systems of these known two-post lifts have many shortcomings, either there is no electrical and hydraulic control for leveling, or the safety warning control configuration is incomplete

[0009] This means that in order to meet the requirements of the two-post lift to ensure the equal height of the left and right lifting slides during installation and use, professional operators and maintenance technicians are required, which will limit the popularization and use of the two-post lift. sales volume

[0010] Furthermore, these known traditional two-column lift electrical and hydraulic control systems do not have a fast, convenient and reliable alarm and automatic leveling method, as well as a compact integrated design
