Abstract
The utility model discloses a drill rod righting mechanism, which comprises two sleeves which are respectively arranged at the side end of a tower frame through a bracket and are used for passing through a drill rod, wherein one sleeve is positioned at the bottom end of the tower frame, and the diameters of the two sleeves are the same; an inner sleeve suitable for drill rods with different diameters penetrates through the sleeve; a circle of fixing groove is formed in the outer wall of the inner sleeve, and two fixing bolts used for fixing the inner sleeve are arranged on the sleeve. The utility model discloses can change the endotheca in different apertures according to the drilling rod of different diameters, be adapted to rightting of a plurality of drilling rod diameters, strong adaptability has both improved the straightness that hangs down of drilling, has still improved the quality of drilling, and the endotheca is fixed through fixing bolt, is convenient for change the endotheca.
Description
Technical Field
The utility model relates to an roofbolter technical field, especially a drilling rod righting mechanism.
Background
The anchor rod is mainly used for rock-soil anchor rods, roadbed and side slope treatment, underground deep foundation pit retaining, tunnel surrounding rock stabilization, landslide prevention and other disaster improvement, underground engineering support and high-rise building foundation treatment. It is also suitable for the non-prestressed anchor rod support of deep foundation pit spray protection and slope soil nail engineering.
When the anchor rod machine punches, in boring into ground or road bed through the drilling rod, because the drilling rod is longer, form for the multisection is connected usually, at the in-process that punches, often arouses the drilling rod to rock because the vibrations of anchor rod machine, is difficult to guarantee the straightness that hangs down of drilling, influences the quality of drilling.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the technical problem that needs to solve provides a mechanism is right to drilling rod, rights the drilling rod, guarantees the straightness that hangs down of drilling, improves the quality of drilling.
In order to solve the technical problem, the utility model adopts the following technical proposal.
The drill rod righting mechanism comprises two sleeves which are arranged at the side end of the tower frame through a support and used for penetrating through a drill rod, wherein one sleeve is positioned at the bottom end of the tower frame, and the diameters of the two sleeves are the same; an inner sleeve suitable for drill rods with different diameters penetrates through the sleeve; a circle of fixing groove is formed in the outer wall of the inner sleeve, and two fixing bolts used for fixing the inner sleeve are arranged on the sleeve.
The drill rod righting mechanism is characterized in that a conical positioning pile extending out of the tower is arranged on the outer side of the support of the sleeve at the bottom end of the tower.
Due to the adoption of the technical scheme, the utility model has the following technical progress.
The utility model discloses can change the endotheca in different apertures according to the drilling rod of different diameters, be adapted to rightting of a plurality of drilling rod diameters, strong adaptability has both improved the straightness that hangs down of drilling, has still improved the quality of drilling, and the endotheca is fixed through fixing bolt, is convenient for change the endotheca.
Drawings
Fig. 1 is a schematic structural view of the present invention;
fig. 2 is a schematic structural view of the inner sleeve according to the present invention;
wherein: 1. the tower comprises a tower frame, 2 parts of a support, 3 parts of a sleeve, 4 parts of a fixing bolt, 5 parts of a positioning pile, 6 parts of a drill rod, 7 parts of an inner sleeve and 8 parts of a fixing groove.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
The drill rod centralizing mechanism is structurally shown in figures 1-2 and comprises a tower 1, a sleeve 3 and a drill rod 6. The sleeves 3 are arranged at the side end of the tower frame 1, and the drill rod 6 penetrates through the two sleeves 3 to be righted so as to ensure the verticality of the drill rod.
The sleeve 3 sets up to two, sets up the side at pylon 1 through support 2 respectively, and two sleeve 3's aperture is the same, and two telescopic centers are on same straight line with the center of drilling rod, when the drilling rod passed two sleeves and drills like this, leads to two sleeves and right, has guaranteed the straightness that hangs down of drilling rod.
One of the sleeves 3 is arranged at the bottom end of the tower frame 1 through a support frame 2, a positioning pile 5 is arranged on the outer side of the support frame 2, and the positioning pile 5 is a conical positioning pile and extends out of the end part of the tower frame 1. When punching, the locating pile 5 withstands the face of punching, and the drilling rod passes the sleeve and punches, has both avoided the drilling rod to rock, has still improved the steadiness of pylon.
If the aperture that punches is less, under the telescopic prerequisite of not demolising, in order to adapt to the drilling rod of different diameters, wear to be equipped with endotheca 7 in sleeve 3's inside, seted up round fixed slot 8 on endotheca 7's the outer wall, be provided with two fixing bolt 4 on sleeve 3's the outer wall, fixing bolt 4 passes telescopic outer wall, on the fixed slot 8 of screw in endotheca 7, fixes the endotheca in the sleeve. The inner sleeves with different apertures can be selected according to the diameter of the drill rod, and the inner sleeves are fixed in the sleeves through the fixing bolts, so that the drill rods with different diameters can be centered.
The utility model discloses when punching, select suitable drilling rod and endotheca according to the size in the aperture of punching, penetrate telescopic inside with the endotheca to fixing bolt 4 fixes, then tightly is punching the locating pile top, and the drilling rod passes endotheca and the locating pile in the sleeve and punches, and at the in-process that punches, two endothecas are right the drilling rod, have reduced rocking of drilling rod, have improved the quality of drilling.
