Embodiment Construction

[0034] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0035] Such as figure 2 , 3 As shown, the real-time monitoring device for the stability of a counterbalanced forklift according to the present invention includes: a data acquisition unit, a signal conditioning unit and a data processing unit. The data acquisition unit includes a steering bridge resistance strain gauge 3 bonded on the upper and lower surfaces of the left and right sides of the forklift steering bridge 1 by superglue, and a piece of outer mast column resistance strain gauge 3 on the outer surface of the left and right columns of the forklift outer mast 2. Sheet 4 and the proximity switch 7 connected by bolts on the swing limit block 6 of the forklift frame. Thus the ground pressure P of the two wheels of the forklift steering axle 1 is collected in real time through the steering axle resistance strain gauge 3 1 The dynamic simulation data of the for...

Abstract

The invention provides a method and a device for the real-time monitoring of the stability of a balance weight type fork truck. The device comprises a data acquisition unit, a signal conditioning unit and a data processing unit, wherein the data acquisition unit comprises force transducers arranged on the left and the right sides of a steering axle of the fork truck, force transducers arranged onthe left and the right upright posts of an outer upright mounting of the fork truck, and a position transducer arranged on a truck frame of the fork truck. The data acquisition unit acquires pressureand position state data of the fork truck under four working conditions in real time, a signal conditioning device of the signal conditioning unit converts the data into standard electric signals andoutputs the standard electric signals to a data processor of the data processing unit; and the data processor processes the received standard electric signals to judge the stability of the fork truckin real time and give an alarm when the fork truck is instable. The method and the device for the real-time monitoring have the advantages of high measurement accuracy, strong practicability, simple mounting and wide application.

Description

technical field [0001] The invention relates to a method for testing the stability of a forklift, and more particularly relates to a method and a device for testing the stability of a counterbalanced forklift in real time. Background technique [0002] Counterbalanced forklift (hereinafter referred to as forklift) is a kind of lifting equipment commonly used in the prior art. Its main structure is as follows: figure 1 Shown include engine 9, gearbox, drive axle 10 (front axle), steering axle 1 (rear axle), vehicle frame 11, mast 12, cargo fork 13, overhead guard 14, counterweight 15 and oil cylinder 16 etc. The mast is the guiding frame for the up and down movement of the cargo fork. It is composed of an inner mast and an outer mast. The outer mast is mainly composed of two C-shaped or J-shaped steel columns. The lower end of the column is fixed on the driving axle, and the upper end is connected by a beam. These two columns support the weight of external loads, forks, mas...
