Detailed description of the invention
Below in conjunction with specific embodiment, this utility model is expanded on further. Should be understood that these embodiments are merely to illustrate this utility model rather than limit scope of the present utility model. In addition, it is to be understood that after having read the content that this utility model is lectured, this utility model can be made various changes or modifications by those skilled in the art, and these equivalent form of values fall within the application appended claims limited range equally.
Embodiment of the present utility model relates to a kind of adjustable crawler chassis, as shown in figures 1 to 6, including left walking beam 1, expansion bracket 3 and right walking beam 4, described expansion bracket 3 is arranged in I shape, it is mounted on hydraulic cylinder 2 in four telescopic arms 9 of this expansion bracket 3, the piston extension bar of two of which hydraulic cylinder 2 is connected with left walking beam 1, the piston extension bar of two other hydraulic cylinder 2 is connected with right walking beam 4, four telescopic arms 9 of described expansion bracket 3 match with the telescopic hole 10 of corresponding left walking beam 1 and right walking beam 4, described left walking beam 1 and right walking beam 4 are mounted on crawler belt 5.
The telescopic hole 10 of described left walking beam 1 and right walking beam 4 connects by bearing pin 12 is fixing with corresponding telescopic arm 9.
Being provided with wearing plate 8 on the sidewall of described telescopic arm 9, this wearing plate 8 is between the telescopic hole 10 of telescopic arm 9 and correspondence.
Described left walking beam 1 and right walking beam 4 lower end have been evenly arranged several thrust wheels 11, described left walking beam 1 and the side of right walking beam 4 are rotatablely equipped with driving wheel 6, the opposite side of this left walking beam 1 and right walking beam 4 is rotatablely equipped with guide wheel 7, and described thrust wheel 11, driving wheel 6 are connected with crawler belt 5 with guide wheel 7.
