Embodiment 1

[0060] The excavator getting off length adjustment system provided in this embodiment includes:

[0061] Get off the walking beam;

[0062] The crawler belt 10 is set around the walking beam for getting off the vehicle;

[0063] The adjustment assembly 50 is adapted to adjust the length of the undercarriage traveling beam and adjust the height of the crawler belt 10 along the longitudinal direction accordingly;

[0064] The adjustment assembly 50 has the extension state of driving the getting off the walking beam to elongate while driving the crawler belt 10 down in the longitudinal direction, and the shrinking state of driving the getting off running beam to shorten while driving the crawler belt 10 to rise in the longitudinal direction state.

[0065] It should be noted that the disembarking walking beam is an important part of the excavator's traveling device, which is symmetrically arranged on both sides of the bottom of the excavator, used to install the traveling motor...

Embodiment 2

[0119] combine Figure 1-Figure 8 As shown, the present embodiment provides an excavator, including:

[0120] Slewing platform, operating room, working arm, and lower frame 60;

[0121] And the above-mentioned excavator getting off length adjustment system arranged on the lower frame 60 .

[0122] The excavator provided in this embodiment overcomes the defect that the excavator in the prior art cannot adjust the grounding specific pressure by setting the length adjustment system for getting off the car, and by adjusting the length of the getting off the car. Excavators that need to adjust the grounding specific pressure increase the stability of the excavator during work.

Abstract

The invention relates to the technical field of construction machinery, in particular to an excavator getting off length adjustment system and the excavator. The excavator disembarkation length adjustment system includes: disembarkation walking beam; crawler belt, which is arranged around the disembarkation walking beam; an adjustment component, which is suitable for adjusting the length of disembarkation walking beam and adjusting the height of the crawler belt along the longitudinal direction; The adjustment assembly has an extended state that drives the undercarriage beam to elongate while driving the track down in the longitudinal direction, and a retracted state that drives the undercarriage beam to shorten while driving the track to rise along the longitudinal direction. The excavator disembarkation length adjustment system provided by the present invention adjusts the length of the dismounted walking beam by setting the adjustment component and adjusts the height of the crawler along the longitudinal direction along with it, so as to realize the self-adaptive adjustment of the constant perimeter of the crawler, which overcomes the problem in the prior art. The defect that the excavator cannot adjust the grounding specific pressure provides an excavator alighting length adjustment system that can adjust the grounding specific pressure as required.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to an excavator getting off length adjustment system and the excavator. Background technique [0002] In the prior art, the walking unit of the excavator often adopts the crawler form. By adopting the crawler form, the contact area between the bottom of the excavator and the ground can be effectively guaranteed, thereby obtaining a small grounding specific pressure, so that the excavator can operate under different working conditions. Do the work below. Although the excavator adopts the crawler form to obtain a small grounding specific pressure, when working in loose soil terrain, if the working height is increased or other functional attachments are added, the chassis will often become unstable when getting off the vehicle. However, the excavator in the prior art does not have a more suitable form to further reduce the ground specific pressure, and cannot guarantee t...
