Device for automatic positioning of electric forklift pallet fork in lifting height and control method thereof

Abstract

The invention discloses a device for automatic positioning of an electric forklift pallet fork in lifting height and a control method thereof. The device comprises a pump controller connected with anoil pump motor, a valve controller connected with a multi-way valve electromagnetic coil and a display instrument connected with an operation switch, the oil pump controller is connected with a main contactor coil, the valve controller is connected with a height encoder, a proximity switch, a lifting electromagnetic valve coil and a descending electromagnetic valve coil, the display instrument isconnected with a fork lifting and descending switch, positive electrode wiring ends of the oil pump controller and the valve controller are both connected with a contact of a contactor in series, anda coil end of the contactor is connected to a control end of the oil pump controller. The electric forklift pallet fork is automatically positioned in lifting height, when a driver takes and places high-position goods, the driver does not need to observe the position of the pallet fork to estimate the lifting height for operation, the pallet fork can automatically reach the lifting height, the operation risk caused by misjudgment of operators is greatly reduced, potential safety hazards are reduced, the working intensity is reduced, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of forklifts, in particular to an electric forklift fork lifting height automatic positioning device and control method. Background technique [0002] Forklifts often need to lift the goods to a certain height during operation. When the volume of the goods is too large or the lifting height is too high, it is difficult for the forklift driver to observe the lifting position of the fork. The risk of in place, currently the market generally adopts the method of installing cameras on the shelves to monitor the in place of forks, but this method still has problems such as the camera being blocked by the goods, the shooting angle of the camera is not suitable, and the super wide installation position of the camera affects the passability of the whole vehicle, etc. . Therefore, it is necessary to design a device that can automatically lift the fork into place, reduce the labor intensity of the driver, and reduce ...
