Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.
Referring to fig. 1 to 3, an ultra-low temperature crawler chassis includes a crawler chassis body including two crawler assemblies symmetrically disposed and a structural member 1 connecting the two crawler assemblies;
each crawler belt assembly comprises a guide wheel 2, a driving wheel 3 and a crawler belt 4 sleeved on the guide wheel 2 and the driving wheel 3, one side of the driving wheel 3 is provided with a traveling speed reducer 5, and the traveling speed reducer 5 drives the driving wheel 3 to rotate so as to drive the guide wheel 2 and the crawler belt 4 to move;
a riding wheel 6 is arranged between the upper part of the structural member 1 and the crawler belt 4;
and a thrust wheel 7 is arranged between the lower part of the structural member 1 and the crawler belt 4.
Wherein, the crawler chassis body is an austenite low-temperature steel crawler chassis body.
In the embodiment, the crawler chassis body is made of austenitic low-temperature steel, so that the crawler chassis has the advantages of low temperature resistance, high structural strength, long service life and the like, and the overall strength is effectively improved. When the crawler chassis is in actual use, the hydraulic motor is started to reduce the speed through the walking speed reducer 5, and the driving wheel 3 is driven to rotate so as to drive the guide wheel 2 and the crawler belt 4 to run, so that the crawler chassis is finally moved.
In particular, with reference to fig. 1, the crawler chassis body further comprises a tensioning device 8, said tensioning device 8 being connected to the guiding wheel 2.
In the embodiment, when in actual use, the pushing resistance is increased due to the fact that the crawler belt is too tight, abrasion is accelerated, the service life of the crawler belt is shortened, and the crawler belt is easy to fall off due to the fact that the crawler belt is too loose; the use of the tensioning device 8 thus allows the track to be suitably tensioned, thereby ensuring proper operation of the track 4.
Specifically, referring to fig. 1, there are two riding wheels 6, and two riding wheels 6 are arranged at intervals.
In this embodiment, the riding wheel 6 is used to support the weight of the upper track 4, and avoid excessive sagging of the track 4, so as to reduce vibration of the upper track 4 during machine movement.
Specifically, referring to fig. 1, the number of the thrust wheels 7 is plural, and the plurality of thrust wheels 7 are uniformly spaced.
In this embodiment, a plurality of thrust wheels 7 are used to transfer the weight of the machine body to the tracks 4 and move the machine body along the track sections; meanwhile, the plurality of thrust wheels 7 are adopted to clamp the crawler belt 4 so as not to slide transversely; during steering, the tracks 4 are forced to slide laterally on the ground.
When the crawler belt chassis is used, the crawler belt chassis body is made of austenitic low-temperature steel, so that the crawler belt chassis has the advantages of low temperature resistance, high structural strength, long service life and the like, and the overall strength is effectively improved. In addition, the sealing element on the crawler chassis is made of fluororubber; wherein, the lubricating oil and the hydraulic oil are both surface low temperature resistant products. When the crawler chassis is in actual use, the hydraulic motor is started to reduce the speed through the walking speed reducer 5, and the driving wheel 3 is driven to rotate so as to drive the guide wheel 2 and the crawler belt 4 to run, so that the crawler chassis is finally moved.
In addition, it should be noted that, the tensioning device, the riding wheel, the supporting wheel and the like related to the embodiment are not essentially different from the prior art, and are not the technical scheme of the important protection of the application, and the technical scheme of the important protection of the application is that the whole structure of the crawler chassis and the whole crawler chassis are made of austenitic low-temperature steel; the structure and working principle of the tensioning device, the idler and the roller in this embodiment will not be described in detail here.
In conclusion, the integral structural member is made of the austenitic low-temperature steel, and the utility model has the advantages of low temperature resistance, high structural strength, long service life and the like, and effectively improves the integral strength.
The foregoing is only a preferred embodiment of the present utility model, but the scope of the present utility model is not limited thereto, and any person skilled in the art, who is within the scope of the present utility model, should make equivalent substitutions or modifications according to the technical scheme of the present utility model and the inventive concept thereof, and should be covered by the scope of the present utility model.
