It should be noted that, the tensioning device 15 may be connected to the guide wheel 16 through a bolt structure to form a tensioning assembly, and the elastic end of the tensioning assembly is connected to the track assembly 17 to adjust the tension of the track assembly 17. The thrust wheel 12 may be formed by welding two wheels. The utility model takes the standard excavator travelling mechanism as the main frame, and by designing the get-off assembly which can be effectively applied to severe working conditions, the construction equipment has better construction operation efficiency, not only improves the construction safety and the travelling reliability, but also has the capability of rapid installation and maintenance without changing the original structure, and provides after-sales service guarantee for the special working condition operation construction.

When the lower vehicle assembly suitable for severe working conditions is used, when the device walks, the driving wheel 10 generates a pulling force under the action of driving moment, the pulling force is used for pulling the track assembly 17 out from the lower part of the supporting wheel 12, the track assembly 17 under the supporting wheel 12 has enough adhesive force with the ground, the pulling out of the track assembly 17 can be prevented, the whole machine is further forced to move forwards against resistance, the driving wheel 10 is enabled to roll the track assembly 17, the guide wheel 16 is used for paving the track assembly 17 on the ground, so that the machine continuously runs forwards along the track assembly 17, and the chain protection mechanism 13 can effectively prevent the track assembly 17 from derailing when the machine walks, so that the machine can normally walk under mine working conditions.
In addition, the wheel body structure of the thrust wheel 12 is changed into an inner and outer double-flange structure 20 from a single outer-flange structure 20, namely, after the original two wheel bodies are welded, a groove with larger space is formed between the two outermost-flange structures 20, so that the derailed track assembly 17 is easily clamped into the groove, and the track assembly 17 is further contacted with a structural member. However, according to the utility model, the flange structures 20 are arranged on the inner side and the outer side of the single wheel body, so that the original groove size can be effectively reduced, the movement range of the track assembly 17 can be limited by the inner flange structure 20 and the outer flange structure 20 of the single wheel body, the derailment probability of the track assembly 17 can be reduced, and meanwhile, the matching operation effect of the track assembly 17 and the thrust wheel 12 can be improved.

On the basis of the above embodiment, it is preferable that the track assembly 17 includes a track link 18 driven in cooperation with the thrust wheel 12 and a track shoe 19 for supporting the track link 18.
It should be noted that the flange structure 20 disposed inside the wheel body may be referred to as an inner flange 21, and the flange structure 20 disposed outside the wheel body may be referred to as an outer flange 22, so that the movement range of the end portion of the track assembly 17 is from the inner flange 21 to the outer flange 22. In particular, the track links 18 may cooperate with the flange structure 20 of the thrust wheel 12, i.e., the end projections of the track links 18 may move between the inner flange 21 and the outer flange 22 to reduce the probability of derailment of the track assembly 17.
Preferably, a chain protection mechanism 13 is arranged between two adjacent thrust wheels 12. That is, each supporting wheel 12 of the lower vehicle assembly 1 is equipped with a chain protection mechanism 13 to protect each supporting wheel 12 and further prevent the derailment phenomenon of the track assembly 17.
Preferably, the chain guard mechanism 13 is connected to the walking frame 9 by bolts.
The chain guard mechanism 13 is mounted on the lower side of the walking frame 9 by bolts so as to prevent the caterpillar assembly 17 from derailing, the mounting mode does not need to change the integral structure of a standard excavator, a support for fixing the chain guard mechanism 13 is not required to be additionally arranged, and the mounting mode is simple and high in universality. In addition, the installation height and the like of the chain guard mechanism 13 are convenient to adjust, so that after the track assembly 17 derails, the chain guard mechanism 13 and the track shoe 19 do not dynamically interfere, and abnormal abrasion of the lower vehicle assembly 1 is reduced.
Besides the fact that the chain protection mechanism 13 can be mounted through bolts, the chain protection mechanism 13 can be directly welded to the lower side of the walking frame 9, the later maintenance difficulty is greatly increased, and after-sales service guarantee cannot be provided for the special working condition operation construction.
On the basis of the above embodiment, it is preferable that the height of the bottom end of the chain guard mechanism 13 is greater than the height of the pin top end of the derailed chain links 18. That is, by adjusting the installation height of the chain guard mechanism 13, collision abrasion between the key connection part (pin shaft) of the chain rail joint 18 and the chain guard mechanism 13 can be effectively prevented when the track assembly 17 derails, so that the pin shaft of the chain rail joint 18 is effectively protected, and the service life and the use effect of the pin shaft are improved.
Preferably, the side plates of the chain guard mechanism 13 are of a wave-shaped structure.
It should be noted that when the machine walks under the severe working condition of the mine, massive rocks 20 often appear under the advancing path of the machine, and the gap between the two supporting wheels 12 is just due to the phenomenon that the rocks 20 cause the inner turnover of the caterpillar track section 18 of the caterpillar track assembly 17, so that the interference phenomenon occurs between the caterpillar track plate 19 and the side plate of the chain guard mechanism 13, and the caterpillar track plate 19 and the chain guard mechanism 13 are worn, so that the side plate of the chain guard mechanism 13 is set to be of a wave-shaped structure according to the running track of the caterpillar track plate 19, and the dynamic interference between the side plate of the chain guard mechanism 13 and the caterpillar track plate 19 can be effectively avoided, thereby reducing the occurrence of abnormal wear problem of the lower vehicle assembly 1.
Preferably, the lower side of the walking frame 9 is provided with a plurality of thrust wheels 12 distributed at intervals; or the underside of the walking frame 9 is provided with a plurality of supporting wheels 12 and supporting wheels which are distributed at intervals in sequence, and the outer side of each supporting wheel is provided with a flange structure 20.
