Embodiment 1

[0028] This embodiment provides a mast 4 shaking detection method suitable for a reach-type forklift, including the following steps:

[0029] (1) When the forklift is fully loaded and not lifted, stretch out to the maximum limit position toward the fork 3 of the forklift; take the middle position of the bottom of the mast 4 as the initial measurement point P2, and place the wire displacement sensor on the At the initial measurement point P2, zero calibration is performed on the stay wire displacement sensor. The initial measurement point P2 is the first installation position 1 of the cable displacement sensor.

[0030] (2) Take the center position of the crossbeam on the fork frame 2 as the initial investigation point O, connect the stay wire of the stay wire displacement sensor to the initial investigation point O; then extend the door frame 4 to the highest limit position in the vertical upward direction , record the distance b between the initial measurement point P2 and t...

Abstract

The invention provides a gantry waggling detection method suitable for a forward-moving forklift which can quantify the specific data of the forklift gantry waggling and can provide more intuitive data for improving the gantry waggling. The beneficial effects of the present invention compared with the prior art are as follows: (1) the detection method provided by the present invention measures thereal-time swing amplitude of the gantry, quantifies the offset of the forklift gantry waggling and provides effective data for improvement of the gantry waggling of the forward-moving forklift; and (2) the operation steps are simple and practicable, the used detection devices are few and low in cost to allow the detection process to be easily implemented, and the measurement is convenient and thecost is low to facilitate large-scale promotion and application.

Description

technical field [0001] The invention relates to the field of electric forklifts, in particular to a mast shake detection method suitable for reach-type forklifts. Background technique [0002] When the reach forklift moves back and forth and lifts and lowers the mast, the mast shakes seriously, especially the high mast. Various methods reduce the shaking of the mast. The mast shake of existing reach trucks is usually detected by naked eye observation, but the method of naked eye observation is highly subjective, and lacks a unified detection standard, resulting in large errors in detection results. Contents of the invention [0003] In order to solve the above-mentioned technical defects existing in the prior art, the present invention provides a detection method for the shaking of the mast of a forward-moving forklift, which can quantify the specific data of the shaking of the mast of the forklift and provide more intuitive data for improving the shaking of the mast. ...
