Specifically, the hinged end of the ramp 100 and the base 200 is provided with a hinged seat, and can be hinged through a pin shaft, the structure of multiple sections of slope bodies can be set to be the same, and the segmented design is carried out along the length direction of the ramp 100, in practical application, the slope bodies with suitable number of sections can be selected for assembly according to the height of the drill floor 800 and the relative position and angle of the base 200 and the drill floor 800, so that the ramp 100 is formed, the lifting angle of the lifting arm 300 and the position of the sliding mechanism 500 can be adjusted to adapt to the drill floors 800 with different heights, and therefore, the power catwalk can adapt to the drill floors 800 with different heights, and the application range is wider.

In this embodiment, by setting the ramp 100 to be a sectional structure, it is able to adapt to drill floors 800 with different heights, and the application range of the power catwalk is increased. And articulated through ramp 100 and base 200, when not carrying the drilling tool operation, ramp 100 can be relative base 200 and rotate to whole the knot is established on base 200, makes this power catwalk wholly be approximate cuboid structure, and then makes overall structure compacter, is convenient for carry out the transportation of changeing.

Although the present disclosure has been described above, the scope of the present disclosure is not limited thereto. Various changes and modifications may be effected therein by one of ordinary skill in the pertinent art without departing from the spirit and scope of the present disclosure, and these changes and modifications are intended to be within the scope of the present disclosure.
