[0019] like Figure 1 As shown, the first embodiment of the present invention provides a rail transit line ice and snow removal device based on the existing technology, including a base assembly 1, a second driving reduction pneumatic motor 2, a T-shaped lower arm 3, a pull rod 4, a V-shaped upper arm assembly 5, a rotating wheel set 6 and a first driving reduction pneumatic motor 7, wherein:

[0020] The top and one end of the base assembly 1 are hinged to the horizontal ends of the T-shaped lower arm 3 and one end of the pull rod 4 respectively. The other ends of the T-shaped lower arm 3 and the pull rod 4 are hinged to the pointed end and the middle part near the pointed end of the V-shaped upper arm assembly 5 respectively. The inner sides of the two side ends of the V-shaped upper arm assembly 5 are equipped with rotating wheel groups 6 for rotation. The two ends of the rotating wheel group 6 are respectively driven by the main shaft of the first driving and reducing air motor 7 arranged on the outer sides of the two side ends of the V-shaped upper arm assembly 5. The horizontal ends of the T-shaped lower arm 3 are driven by the main shafts of the two second driving and reducing air motors 2 on the base assembly 1.

[0021] like Figure 2 As shown, the base assembly 1 includes a base 12, and insulating porcelain bottles 11 are respectively installed at the four corners of the bottom of the base 12. Lower arm ears 13 are vertically symmetrically fixed on the top of the base 12. Two second driving and reducing pneumatic motors 2 are respectively fixed on the outside of the two lower arm ears 13, and the horizontal ends of the T-shaped lower arm 3 are respectively connected to the main shaft of the second driving and reducing pneumatic motor 2 through the two lower arm ears 13.

[0022] like Figure 3 and 4As shown, the rotating wheel group 6 includes an intermediate rotating shaft 61 with both ends mounted on the inner side of the two side ends of the V-shaped upper arm assembly 5, and a tripod 63 is symmetrically sleeved on the intermediate rotating shaft 61.
