Embodiment Construction

[0020] The specific implementation will be described below in conjunction with the accompanying drawings.

[0021] In the present invention

[0022] Such as Figure 1 to Figure 4 As shown, the excavator in this embodiment includes a lower traveling mechanism, a slewing platform positioned at the upper part of the traveling mechanism, a working device, a counterweight, and a hydraulic system. An articulated arm, a bucket articulated with the arm, and an arm cylinder (not shown) connected between the arm and the slewing platform.

[0023] The counterweight is set at the rear of the platform; there is a slide rail on the slewing platform, and the counterweight is slid on the slewing platform through the slide rail, and a hydraulic cylinder with the counterweight sliding on the slide rail is set between the counterweight and the slewing platform .

[0024] The lower walking mechanism includes the lower frame and crawler belts. The slewing platform is slewing and installed on t...

Abstract

The invention relates to control over excavators and provides a control method for preventing tipping of an excavator. By the adoption of the control method, the problem that according to an existing excavator, machine tipping cannot be effectively prevented is solved. The control method comprises the following steps that the stabilizing moment and capsizing moment of the excavator are calculated in real time; a stability coefficient is calculated according to the stabilizing moment and capsizing moment; when the stability coefficient is smaller than a preset value, a counterweight of the excavator is moved backwards till the stability coefficient is larger than the preset value; and when the stability coefficient is smaller than the preset value and the counterweight of the excavator is moved backwards to a limit position, a tipping danger alarm is given by an alarm unit.

Description

technical field [0001] The invention relates to a control method of an excavator, more specifically, to a control method for preventing the excavator from tipping over and the excavator. Background technique [0002] Excavators are the main equipment for earthwork engineering. The working environment of the excavator is complex, the working conditions are changeable, and the working forms are various. Operational safety depends entirely on the experience and ability of the driver. When the excavator is working on a relatively large slope and performing hoisting operations on potholed roads, the excavator is prone to instability. In serious cases, the excavator will overturn. [0003] Many existing excavators are equipped with anti-tipping monitoring devices, but this monitoring device is only for monitoring and alarming when the excavator is in danger of tipping over, it cannot effectively prevent the excavator from tipping over, and the stabilizing moment of the excavator...
