Forklift automatic vehicle-driving-back method and vehicle-driving-back device

Abstract

The invention discloses a forklift automatic vehicle-driving-back method. The method comprises the following steps that an automatic vehicle-driving-back function is started; whether a forklift meetsthe safety performance requirement of automatic vehicle-driving-back or not is judged; parameters of a forklift door frame and a forklift fork are detected; and whether the parameters of the forkliftdoor frame and the forklift fork are within a target parameter range or not is judged, wherein the forklift door frame parameter comprises a forklift door frame tilt angle, and the forklift fork parameter comprises a fork height, a fork position and a fork spacing. According to the method, the forklift door frame angle, the forklift fork height, the forklift fork position, the forklift fork spacing and other parameters are detected to be compared with target parameters, the forklift door frame angle, the forklift fork height, the forklift fork position, the forklift fork spacing and other parameters are automatically adjusted, in the adjustment process, changes of the adjusted parameters are detected in real time, and feedback adjustment is carried out, so that the accuracy of the adjustment method is improved, the vehicle-driving-back speed is increased, and the labor intensity of workers is reduced.

Description

technical field [0001] The invention relates to the technical field of forklift retraction, in particular to an automatic retraction method and an automatic retraction device for forklifts. Background technique [0002] After the forklift is used, adjust the fork and mast to a safe state: drop the fork to a low position, adjust the inclination of the mast to an appropriate position (different products are slightly different), and adjust the position and spacing of the fork to an appropriate position. [0003] The operator needs to control the lifting or lowering of the fork, tilting the mast forward or backward, moving the fork sideways, adjusting the distance, etc., and it will take a certain amount of time for the unskilled operator to perform the above operations. It can achieve the ideal state of car collection, and with the continuous development of the forklift industry, there will be more and more functions of the mast part. At this time, the manual operation alone is...

Problems solved by technology

[0003] The operator needs to control the lifting or lowering of the fork, tilting the mast forward or backward, moving the fork sideways, adjusting the distance, etc., and it will take a certain amount of time for the unskilled operator to perform the above operations and not necessarily It can achieve the ideal state of car collection, and with the continuous development of the forklift industry, more and more functions of the mast will be added. At this time, it is cumbersome and inaccurate to operate it manually, and it is time-consuming and labor-intensive.
