Preferably, when the second piston rod 9 of the compound oil cylinder 7 moves downwards, the frame bottom plate 5 can move downwards (the frame bottom plate 5 moves downwards away from the frame connecting plate and is separated from the fixed column and the hexagonal track), and the sliding seat of the gyrator 1 moves from top to bottom along the hexagonal track. After the anchor rod is installed, the second piston rod 9 of the compound cylinder 7 moves upwards, so that the frame bottom plate 5, the gyrator 1 and the like move upwards, and the drilling compensation cylinder 2 also cooperates with advanced compensation feeding.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and not for limiting the same; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the invention.
