Abstract
The utility model discloses a kind of special-shaped auger stem, comprise the body of rod, body of rod one end arranges male joint, the other end arranges female joint, axially extending bore is provided with in the body of rod, axially extending bore one end is communicated with male joint, the other end is communicated with female joint, is installed with spacer ring around the spiral bar being arranged on body of rod outer ring between male joint and female joint, and the outer peripheral surface of the body of rod is provided with three helicla flutes, three helicla flutes are the uniform setting of central axis around the body of rod, and spiral fluted groove bottom is arc surface.The utility model a kind ofly has the abnormal-shaped screw drilling rod turning over slag, deslagging function.
Description
Technical field
The utility model belongs to mining drilling field of mechanical technique, relates to a kind of mining drill rod special, particularly relates to a kind of abnormal-shaped screw drilling rod being mainly used in coal mine gas drainage, visiting water, visit tomography and down-hole weak seam.
Background technology
At present, the drilling rod that underground coal mine uses mostly is polish drill rod, Three-edged drill stem and general auger stem.Although polish drill rod in hard and above coal seam result of use good, in the drilling in coal process of heavily stressed, high methane, often run into the situation such as collapse hole, plug-hole; Although what Three-edged drill stem added drilling rod turns over slag ability, easily there is the smooth stuck phenomenon of deslagging; Although general auger stem deslagging is smooth but turn over slag ability, so these three kinds of form drilling rods are once occurring collapse hole, plug-hole, deslagging and turn over the phenomenons such as slag can be all that drilling rod cannot creep into, and likely there is the drilling accident such as bit freezing, bury drills.
Utility model content
The purpose of this utility model is to provide a kind ofly has the abnormal-shaped screw drilling rod turning over slag, deslagging function.
For achieving the above object, the utility model adopts following technical scheme: a kind of special-shaped auger stem, comprise the body of rod, body of rod one end arranges male joint, the other end arranges female joint, axially extending bore is provided with in the body of rod, axially extending bore one end is communicated with male joint, the other end is communicated with female joint, spacer ring is installed with around the spiral bar being arranged on body of rod outer ring between male joint and female joint, the outer peripheral surface of the body of rod is provided with three helicla flutes, three helicla flutes are the uniform setting of central axis around the body of rod, and spiral fluted groove bottom is arc surface.
The described body of rod, male joint, female joint and spiral bar are integral type structure.
The cross section of described axially extending bore is triangular shape or circle.
The special-shaped auger stem of one described in the utility model, offer three helicla flutes vertically, spiral fluted groove bottom is arc surface, is conducive to turning over slag and deslagging in drilling process; The axially extending bore of the body of rod can be used for water flowing or ventilation, and forms effective waterpower or wind power slag-discharging system, thus drilling rod work plane is served to the effect of continuous cooling, substantially increases the safety of coal mine operation; The simultaneously friction of the body of rod and coal seam and rock stratum reduces, in turn save activity duration, hole quality high, improve drilling efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A view in Fig. 1.
Detailed description of the invention
By the special-shaped auger stem of the one shown in Fig. 1-Fig. 2, comprise the body of rod 2, the body of rod 2 one end arranges male joint 1, the other end arranges female joint 5.Axially extending bore 6 is provided with in the body of rod 2, axially extending bore 6 is through hole, axially extending bore 6 one end is communicated with male joint 1, the other end is communicated with female joint 5, the cross section of described axially extending bore 6 is triangular shape, certainly, the utility model is not limited to above-mentioned form, and the cross section of axially extending bore 6 also can be circle, and namely axially extending bore 6 is manhole.
Between male joint 1 and female joint 5, be installed with spacer ring around the spiral bar 4 being arranged on the body of rod 2 outer ring, spiral bar 4 is the rib extended twist, and spiral bar 4 spacer sleeve is located at the body of rod 2 outer ring and and is provided with gap between the body of rod 2.
The described body of rod 2, male joint 1, female joint 5 and spiral bar 4 are integral type structure.
The outer peripheral surface of the body of rod 2 is provided with three helicla flutes 3, and helicla flute 3 extends in the shape of a spiral vertically, and three helicla flutes 3 are the uniform setting of central axis around the body of rod 2, and the groove bottom of helicla flute 3 is arc surface, and the bottom land of the cross section of helicla flute 3 is circular arc.The rotation direction of three helicla flutes 3 is all identical.
Described helicla flute 3 extends to the outer peripheral surface of male joint 1.Several abnormal-shaped screw drilling rod is when connecting successively, the female joint 5 of front abnormal-shaped screw drilling rod is threaded in the male joint 1 of rear abnormal-shaped screw drilling rod, and the helicla flute 3 of the body of rod 2 of front abnormal-shaped screw drilling rod can correspondingly with the helicla flute 3 of the male joint of rear abnormal-shaped screw drilling rod be connected.
The special-shaped auger stem of one described in the utility model, offers three helicla flutes 3 vertically, and the groove bottom of helicla flute 3 is arc surface, is conducive to turning over slag and deslagging in drilling process; The axially extending bore 6 of the body of rod 2 can be used for water flowing or ventilation, and forms effective waterpower or wind power slag-discharging system, thus drilling rod work plane is served to the effect of continuous cooling, substantially increases the safety of coal mine operation; Simultaneously the body of rod 2 reduces with the friction of coal seam and rock stratum, in turn save activity duration, hole quality high, improve drilling efficiency.
