[0022] By installing a support arm 3 on the outer wall of the chassis body 1, and a fixed column 5 and a hydraulic drive rod 4 on the bottom of the chassis body 1, the use angle of the support arm 3 can be changed under the action of the hydraulic drive rod 4, so that the driving wheel 6 on the outer wall of the support arm 3 can contact the ground, thereby supporting the equipment as a whole and allowing the outer wall of the walking track 2 to leave the ground.

[0023] In a preferred embodiment, a rotating base is fixedly mounted on the outer wall of the support arm 3 , and the outer wall of the hydraulic drive rod 4 at one end away from the fixed column 5 is rotatably connected to the rotating base on the outer wall of the support arm 3 .

[0024] By installing a rotating base on the outer wall of the support arm 3, the two ends of the outer wall of the hydraulic drive rod 4 are rotatably connected to the outer wall of the fixed column 5 and the outer wall of the support arm 3 respectively, so that the support arm 3 can be deflected at an angle under the action of the hydraulic drive rod 4, so that the outer wall of the driving wheel 6 contacts the ground or leaves the ground.

[0025] In a preferred embodiment, there are four support arms 3 , and the four support arms 3 are respectively installed in groups of two on both sides of the outer wall of the chassis body 1 .

[0026] By installing multiple support arms 3 on both sides of the outer wall of the chassis body 1, the driving wheels 6 on both sides are lifted up by the support arms 3, so that the height and position of the driving wheels 6 can be adjusted under the action of the support arms 3 and the hydraulic drive rod 4, thereby achieving the lifting of the entire chassis body 1.

[0027] In a preferred embodiment, a limiting hole is provided on the outer wall of the support arm 3 , and the inner wall diameter of the limiting hole matches the outer wall diameter of the limiting rod 11 .

[0028] Through the limiting hole opened on the outer wall of the support arm 3, the limiting rod 11 can enter the inner cavity of the limiting hole under the action of the driving spring 10, thereby realizing the limitation of the support arm 3 under the action of the limiting rod 11 and the fixing plate 7, so that the angle of the support arm 3 is fixed, so that the driving wheel 6 can more stably support the chassis body 1.

[0029] In a preferred embodiment, two ends of the outer wall of the driving spring 10 are in contact with the inner wall of the movable groove 8 and the outer wall of the limiting rod 11 respectively, and the driving spring 10 is made of high carbon steel.

[0030] By setting the driving spring 10 in the inner cavity of the movable groove 8, the limiting rod 11 can be pushed into the inner cavity of the support arm 3 under the action of the driving spring 10, and the supporting angle of the support arm 3 is limited, thereby supporting the chassis body 1 more stably.

[0031] In a preferred embodiment, a sliding groove is provided on the outer wall of the fixing plate 7 , and the inner wall shape of the limiting groove 9 matches the outer wall shape of the pull rod 12 .

[0032] By means of the limiting groove 9 opened on the outer wall of the fixing plate 7, when the equipment uses the walking track 2 to walk, the driving wheel 6 needs to leave the ground under the action of the hydraulic driving rod 4, and the limiting rod 11 needs to be pulled out from the inner cavity of the support arm 3. By pulling the pull rod 12 and making the pull rod 12 enter the inner cavity of the limiting groove 9, the limiting rod 11 will not enter the inner cavity of the support arm 3 under the action of the pull rod 12 and the limiting groove 9.

[0033] Working principle: When the above equipment is in use, when the equipment is in some field with poor road conditions, the walking crawler 2 is used to walk. At this time, the support arm 3 is lifted up by the hydraulic drive rod 4. As the hydraulic drive rod 4 is extended, the support arm 3 can be rotated upward, so that the outer wall of the driving wheel 6 leaves the ground. When the equipment is walking on some ground with good road conditions, the driving wheel 6 is used to walk. By starting the hydraulic drive rod 4 again, the support arm 3 is pulled downward under the action of the hydraulic drive rod 4, so that the support arm 3 rotates downward, and the support arm 3 is rotated during the rotation process. The outer wall of the driving wheel 6 contacts the ground, thereby gradually lifting up the chassis body 1. When the outer wall of the driving wheel 6 completely contacts the ground, the outer wall of the limit rod 11 will correspond to the position of the upper limit hole on the outer wall of the support arm 3. Then the pull rod 12 is pulled out from the inner cavity of the limit groove 9 to allow the limit rod 11 to enter the inner cavity of the support arm 3. At this time, the support arm 3 can better support the chassis body 1 under the joint action of the hydraulic driving rod 4 and the limit rod 11, so that the walking track 2 leaves the ground and uses the driving wheel 6 to walk, so that the equipment has better maneuverability.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
