Overhead crane walking shaft for collaborative robot

The invention provides an overhead crane walking shaft for a collaborative robot, and belongs to the technical field of automatic equipment. The overhead crane walking shaft for the collaborative robot comprises a stand column part, an overhead crane cross beam part, a movable sliding table part and an organ cover protection structure. The overhead crane cross beam part is supported by the stand column part, the movable sliding table part is arranged on the overhead crane cross beam part in a sliding manner and serves as an installation carrier of the collaborative robot, and therefore when the movable sliding table part moves on the overhead crane cross beam part, through linkage of the movable sliding table part and the collaborative robot, the collaborative robot has the larger stroke,the work range is enlarged, the multi-station use requirement is better met, and the use limitation is reduced; and in addition, the organ cover protection structure is arranged between the movable sliding table part and the
