The utility model discloses a telescopic auger stem, including main part steel pipe 1, main part steel pipe 1 is the pipe column structure. The side of the main body steel pipe 1 is provided with the helical blade 2, and the helical blade 2 is used for attacking into the soil layer and discharging drilling slag in the process of drilling the pile foundation. As shown in the figure, the helical blade 2 is a rotating structure and is wound on the outer side surface of the main steel pipe 1.
The below of main part steel pipe 1 is provided with drill bit 3, and in this embodiment, drill bit 3 is most advanced structure, improves telescopic auger stem's the ability of attacking into. Generally, the drill bit 3 includes a bit body 4, the bit body 4 having a tapered shape, and bit blades 5 provided on the side of the bit body 4. As shown in the drawing, the drill blade 5 has a gradually increasing outer diameter from bottom to top, and has a strong attack capability.
The main body steel pipe 1 is internally fixed with a sleeve 6 and a slidable telescopic drill rod 7 which is sleeved with the sleeve 6. In this embodiment, the telescopic drill rod 7 is a rigid structure as a whole, which is movable in the axial direction relative to the casing 6, forming a telescopic structure. As shown in the figure, the telescopic drill rod 7 is sleeved on the inner side of the casing 6 and is arranged coaxially, and when the telescopic drill rod 7 and the casing 6 are not locked, the telescopic drill rod 7 can slide relatively relative to the casing 6.
The fixing pin 9 is inserted into the casing 6 and the telescopic drill rod 7, and as shown in the figure, the casing 6 and the telescopic drill rod 7 are both provided with a fixing hole 8 for the fixing pin 9 to be inserted, so that the fixing pin 9 is inserted into the casing 6 and the telescopic drill rod 7. When the fixing pin 9 is inserted through the casing 6 and the telescopic drill rod 7, the casing 6 and the telescopic drill rod 7 are locked and remain relatively fixed in the axial direction. Usually, the upper part and the lower part of the telescopic drill rod 7 are both provided with fixing holes 8, and when the fixing hole 8 at the upper part of the telescopic drill rod 7 is opposite to the fixing hole 8 on the sleeve 6, the whole telescopic spiral drill rod is shorter; when the fixing hole 8 at the lower part of the telescopic spiral drill rod 7 is opposite to the fixing hole 8 on the sleeve 6, the whole telescopic spiral drill rod is longer. In one embodiment, the sleeve 6 is a square tube. The telescopic drill rod 7 is a square pipe. The inner diameter of the casing 6 is slightly larger than the outer diameter of the telescopic drill rod 7. By adopting the section shape, the large torque can be transmitted by utilizing the matching structure of the sleeve 6 and the telescopic drill rod 7, and the excessive stress of the locking pin is avoided. In another embodiment, the cross-section of the casing 6 and the telescopic drill rod 7 may also take other polygonal shapes.
The top of the telescopic drill rod 7 is fixed with a flange plate 10. The flange 10 is connected with a power supply. Typically, the flange 10 is welded to the telescopic drill rod 7.
The telescopic auger stem of the utility model adopts the structure that the sleeve 6 is fixed inside the main steel pipe 1, the telescopic auger stem 7 connected with the power supply and the sleeve 6 can move axially, and the like, when in specific application, when only a shallower pile foundation needs to be obtained, the telescopic auger stem can be deeply inserted into the sleeve 6, the sleeve and the sleeve are sleeved and overlapped for a longer part, and the shallower pile foundation can be obtained by construction under the state; in order to obtain darker pile foundation, can be earlier with gentle contract drilling rod deepening to in the sleeve pipe 6, both cup joint the overlap portion longer, obtain shallower pile foundation earlier under this state, then extract telescopic auger stem is whole from the pile foundation, pull out fixed pin 9 after, outwards pull out one section with telescopic auger stem 7, reuse fixed pin 9 locks sleeve pipe 6 and telescopic auger stem 7 again, telescopic auger stem is whole longer this moment, carry out further drilling and obtain darker pile foundation to shallow pile foundation this moment. It can be understood that in the process of drilling the pile foundation of the deep pile, the distance of the telescopic spiral drill rod on the ground is relatively short, and in the specific application, the rotation shaking degree is relatively light, and the work is more stable. It should be noted that for softer soil, the pile is drilled directly after the overall longer telescopic auger stem is adjusted, so as to drill a pile body with a depth greater than that of the tower.
In one embodiment, the fixing pin 9 is inserted through the main steel pipe 1, the casing 6 and the telescopic drill rod 7. In the present embodiment, the main steel pipe 1, the sleeve 6, and the telescopic individual rod are each provided with a fixing hole 8 in which a fixing pin 9 is installed.

Usually, the fixing pin 9 is in threaded connection with the main steel pipe, and the distal end of the fixing pin adopts a tapered structure, so that the fixing pin can be conveniently inserted into the fixing hole 8 of the telescopic drill rod 7. With this construction, the fixing pin 9 is more resistant to bending.
Of course, in another embodiment, the main steel pipe 1 is provided with an operation hole, the inner diameter of which is much larger than the fixed pin 9, so that the fixed pin 9 extends into the main steel pipe 1 to realize the pin connection of the casing 6 and the telescopic drill rod 7.
In another embodiment, the fixing pin 9 is detachably inserted into the main steel pipe 1 and the telescopic drill rod 7, that is, the sleeve 6 is not provided with a fixing hole for assembling the fixing pin 9, but is provided with an opening structure for integrally exposing the fixing hole on the telescopic drill rod 7, and the fixing pin 9 is only used for locking the telescopic drill rod 7 and the main steel pipe 1 with each other.
In this embodiment, a fixing plate 11 is disposed between the main steel pipe 1 and the sleeve 6. The main steel pipe 1 and the sleeve 6 are connected more firmly by the structure of the fixing plate 11, and larger torque can be transmitted. In general, the fixing plate 11 is continuous between the main steel pipe 1 and the sleeve 6, and also functions as a closed space.
As shown in the figure, the lower end of the main steel pipe 1 is provided with a mounting flange 12, and the drill bit 3 is connected with the mounting flange 12. Through the structure of arranging the mounting flange 12, the drill bit 3 can be repeatedly disassembled, assembled and welded. In another embodiment, the upper and lower parts of the main steel pipe 1 are provided with the mounting flanges 12, and when the telescopic spiral drill pipes are used in a specific application, the telescopic spiral drill pipes can be coaxially connected in sequence, so that the telescopic spiral drill pipes can be lengthened according to different pile lengths.
