Embodiment 1

[0054] combine figure 1 As shown, the excavator gauge adjustment method for getting off the vehicle provided in this embodiment includes:

[0055] S11. Obtain the working condition data of the excavator.

[0056] In the embodiment of the present invention, a detection device is pre-set at a corresponding position of the excavator, and the detection device includes at least one of: a laser range finder, a load cell, a position sensor or a slope angle measuring device. Obtain the working condition data of the excavator through the detection equipment. Wherein, the working condition data includes but not limited to: overturning moment, stabilizing moment, and current alighting gauge. When the side of the excavator bucket is working, the excavation reaction force of the bucket forms an overturning moment on the excavator, which is easy to cause the excavator to overturn. The overturning moment and stabilizing moment are used to determine the current stability state of the excav...

Embodiment 2

[0067] combine figure 2 As shown, another excavator gauge adjustment method provided in this embodiment includes:

[0068] S21. Determine a stabilizing torque based on the working condition data.

[0069] In the embodiment of the present invention, the stabilizing moment is the maximum overturning moment that the excavator can bear under the current operating state, and the stabilizing moment is related to the angle of the slope where the excavator is located, the angle between the boom 95 of the excavator and the longitudinal direction, The included angle between the lower beam of the excavator and the longitudinal direction is in a corresponding relationship, wherein the longitudinal direction referred to here refers to the direction perpendicular to the direction of travel when the excavator is traveling directly against the slope. The working condition data includes but not limited to: overturning moment, current alighting gauge, slope angle or boom working direction, et...

Embodiment 3

[0087] combine Figure 4 , Figure 5 As shown, the present embodiment provides an excavator, including:

[0088] The first lower beam 91 and the second lower beam 93;

[0089] The first hydraulic cylinder 92 and the second hydraulic cylinder 94 drive the first lower beam 91 and the second lower beam 93 respectively, and are suitable for adjusting the first lower beam 91 and the second lower beam. The distance between the beams 93.

[0090] Preferably, the undercarriage of the excavator is provided with two undercarriage beams, respectively the first undercarriage beam 91 and the second undercarriage beam 93, and the first undercarriage beam 91 and the second undercarriage beam 93 are arranged in parallel . The first lower beam 91 and the second lower beam 93 are respectively connected with the first hydraulic cylinder 92 and the second hydraulic cylinder 94. Preferably, the push rods of the first hydraulic cylinder 92 and the second hydraulic cylinder 94 are connected with...

Abstract

The invention relates to the technical field of excavators, in particular to a method and a device for adjusting the unloading track gauge of an excavator and the excavator. The method for adjusting the unloading track gauge of the excavator comprises the following steps that 1, working condition data of the excavator are obtained; 2, the stable state of the excavator is determined based on the working condition data; and 3, on the basis of the stable state, the unloading track gauge of the excavator is controlled, so that the excavator can automatically adjust the unloading track gauge of the excavator according to the on-site operation working condition, the excavator is stable, and overturning of the excavator is avoided.

Description

technical field [0001] The invention relates to the technical field of excavators, in particular to a method and device for adjusting the track gauge of an excavator when getting off the vehicle, and the excavator. Background technique [0002] The operation stability of the excavator has a great influence on the work of the whole machine. An excavator with good stability can not only ensure safe operation, but also exert the best excavation performance within the operating range. When the excavator is working on a slope, the bucket excavation reaction force forms a lateral overturning moment on the excavator. When the overturning moment is too large, the whole machine is prone to overturning. Therefore, it is necessary to improve the stability of the excavator during work. . In the prior art, the left and right track gauges can be adjusted by adjusting the fixed positions of the left and right longitudinal beams and the main frame, and the operation stability of the excava...
