[0001] The utility model relates to the technical field of cantilever robot mobile equipment, in particular to a mobile driving device. Background Art

[0002] The cantilever robot usually needs to move in three directions, namely, in the X-axis, Y-axis and Z-axis directions. In the prior art, the movement is usually performed by a crane.

[0003] The sliding rails on the prior art cranes (the specific structure can be found in Chinese invention patent: CN 117564575A) are prone to dust accumulation, and workers need to clean them in time to keep the sliding surface of the sliding rails clean. However, this manual cleaning method does not clean the dust in time, and also increases the maintenance and servicing costs of the cranes.

[0004] That is to say, in the prior art, the dust accumulated on the sliding surface is not cleaned in time. Utility Model Content

[0044] like Figure 1 and Figure 2As shown, the utility model provides a mobile driving device, which includes a track assembly 10, a sliding assembly 20 and a driving assembly 30. The track assembly 10 is extended along a first direction; the sliding assembly 20 is arranged on the track assembly 10, and the sliding assembly 20 is slidably connected with the track assembly 10 in the first direction; the driving assembly 30 is arranged on the sliding assembly 20, and the driving assembly 30 is used to drive the sliding assembly 20 to slide on the track assembly 10; the track assembly 10 includes a sliding track 11, and the sliding track 11 is a triangular track, and the sliding assembly 20 slides on the two sides of the two waists of the triangular track at the same time.
