Specific embodiment
Embodiment 1：As shown in Figure 1, the present embodiment is a kind of auxiliary anchor pole positioning, anchor pole is made to be located in drilling 1 and drilling 1
The 2 centering stent of anchor pole of concentric position coaxial, the locking piece being used cooperatively including connector and with connector.
As shown in Figure 2 and Figure 3, connector has connecting circular tube 4, and the internal diameter of the connecting circular tube and anchor pole 2 in the present embodiment
Diameter is adapted, and connecting circular tube 4 is divided into two sections along its axial direction, and one section is the external thread section for being formed with external screw thread 5, the company of external thread section
Two axially opens 6 being provided on 4 tube wall of pipe along the elongated arrangement of external thread section are connect, two axially opens 6 are in 4 end face of connecting circular tube
It is distributed in "-" type, several raised floating points 7 is formed on the corresponding inner surface of external thread section of the connecting circular tube；On connecting circular tube 4
Connecting circular tube 4, can be positioned at by another section of auxiliary positioning section that auxiliary positioning mechanism is formed with for outer wall by auxiliary positioning mechanism
Drill middle position, concentric coaxial with drilling 1.
As shown in Figure 4, Figure 5, locking piece has locking pipe 9 in this example, and 9 internal diameter of locking pipe is slightly larger than bolt diameter.
Locking pipe 9 is formed with internal thread 11, and the internal diameter of internal thread segment is tapered into along locking pipe 9 is axial, and the internal thread segment is larger
The internal diameter at end is adapted with the outer diameter of external thread section on connector.Locking 9 outer wall of pipe is formed with auxiliary positioning mechanism, passes through auxiliary
The connecting circular tube 4 being threadedly coupled with locking piece can be positioned at drilling middle position by detent mechanism, concentric coaxial with drilling 1.
Auxiliary positioning mechanism in the present embodiment on connecting circular tube 4 is 6 edge connections being fixed on 4 outer wall of connecting circular tube
I 8,6 wing plates I 8 of wing plate of 4 radial arrangement of pipe are distributed in rice font.The auxiliary positioning machine on pipe 9 is locked in the present embodiment
Structure is that 6 II 10,6 wing plates II 10 of wing plate along 4 radial arrangement of connecting circular tube being fixed on locking 9 outer wall of pipe are in rice word
Type is distributed.The height of wing plate I 8 is gradually reduced from one end close to external thread section to the other end；The height of wing plate II 10 is from close
The internal diameter of internal thread 11 is gradually reduced compared with big end to the other end, and the wing plate I, II of height change is conducive to centering stent in drilling 1
It is moved forward and backward, the channel that the space between wing plate I, II is flowed as mortar.
The application method of the present embodiment is as follows：
Connector and locking piece are set in the position for needing to install centering stent on anchor rod body.
Turn-knob connector and locking piece make the two connect by the external screw thread 5 of connector and 11 screw thread of internal thread of locking piece
It connects；The internal diameter that the two is threadedly coupled internal thread 11 in rundown process is gradually reduced, and since 5 sections of the external screw thread of connector is formed with
Axially open 6, so as to make 5 sections of compression anchor poles of external screw thread of connector, the raised floating point 7 of connector inner surface is adjacent to anchor pole bar
Body increases the friction of centering stent and anchor rod body, and centering stent is made to be not easy positioning.
