The beneficial effect of this scheme is:
1. On the current rotary jumbolter, the track is spacing with the draw-in groove only in dependence of being connected of base, and the track comprises the flanging of frame type frame, and the vibration that produces in the drilling process can cause drilling precision to appear the deviation, and this embodiment sets up two guide pillars that are parallel to each other with the track in the outside of frame type frame, and the sliding sleeve on the guide pillar links to each other with the base, restricts the degree of freedom of base in axial and horizontal direction through the slip of sliding sleeve to promote the feeding stability of whole base, improve the precision of drilling.
2. The rear portion of the existing track is of an open type, the whole base easily slides out of the track when the track is in an elevation angle, so that the angle range of the whole drilling hole is limited.
Further, two ends of the guide post are fixed on the side wall of the frame-type rack through a jacket, and one end, close to the side wall, of the jacket is connected with the side wall through a bolt. The guide post can be detached from the whole frame type rack, so that the assembly is convenient.
Further, the guide pillar is cylindrical, and the sliding sleeve is cylindrical. The friction force between the guide post and the sliding sleeve is reduced, and the feeding is smooth.
Further, the connecting piece is long platy, and the one end that the connecting piece is close to the sliding sleeve is connected with sliding sleeve bolted connection, and the one end that the connecting piece is close to the base extends to the base bottom level to be connected with the lateral wall of base through the bolt.
Further, the number of the sliding sleeves is two. The pushing force of the base is evenly distributed on the two sliding sleeves
Further, the inner peripheral wall of the sliding sleeve is provided with a graphite layer. The graphite layer has lubricating effect and is convenient for the sliding sleeve to reciprocate.
Further, the bottom surfaces of the two side walls of the base are inwardly folded. The side wall of the base is limited, and the base is connected with the rail more tightly.
