Embodiment Construction

[0016] exist figure 1 Fig. 1 schematically shows a flow chart of a method for dynamic front rollover protection of a forklift according to the present invention. exist figure 1 In the process, the load weight m of the forklift, the lifting height L of the mast of the forklift, the inclination angle θ of the mast of the forklift and the slope of the ground α are firstly detected.

[0017] However, the critical braking acceleration a is calculated from the detected load weight m, lift height L, inclination angle θ and said ground gradient α. Finally, the critical braking force p is calculated from the calculated critical braking acceleration a.

[0018] In the next step, compare the current braking force p1 with the critical braking force p, if the current braking force p1 is greater than or equal to the critical braking force p, an alarm will be issued and the braking device of the stacker will be controlled to Reduce the current braking force p1.

[0019] In the method acc...

Abstract

A dynamic front roll-over protection method of a stacking machine comprises the following steps: a) detecting the load weight (m) of the stacking machine, the lift height (L) of the stacking machine gantry, the angle of inclination (theta) of the stacking machine gantry, the surface slope (alpha) and the current braking force (pl); b) computing the critical braking force (p) according to the detected load weight signal, lift height signal, signal of angle of inclination and surface slope signal; and c) comparing the current braking force (pl) and the critical braking force (p), alarming and controlling a brake device of the stacking machine to reduce the current braking force (pl) if the current braking force is more than or equal to the critical braking force. In addition, the invention also relates to a dynamic front roll-over protection system of the stacking machine and the stacking machine with the protection system, wherein the system is used for implementing the above method.

Description

technical field [0001] The invention relates to a dynamic front tipping protection method of a stacker, a dynamic front tipping protection system of a stacker for implementing the method, and a stacker with the system. Background technique [0002] For container stackers, the position of the center of gravity of the vehicle and the stability of the vehicle will change with the height of the hanging box, the weight of the hanging box and the swing angle of the mast. During the dynamic driving process of the forklift, stepping on the brake may cause the risk of forward tipping due to excessive braking torque due to overcoming the forward tipping moment, thereby reducing the longitudinal stability or safety. Moreover, the judgment and prevention of this kind of forward tipping safety hazards are completely dependent on the driver's personal experience and operating habits. If the human operation factor is too large, forward tipping will inevitably occur. Related products have r...
