Description
Technical field
The utility model relates to a kind of colliery tunnel support anchoring drilling rod, particularly a kind of colliery tunnel support anchoring fast joint type drilling rod.
Background technology
Supporting in process of production, must be carried out to underworkings in colliery, generally adopts anchor pole or anchor cable to carry out its support reinforcement to tunnel in China, and this just needs to creep into roadway surrounding rock punching, and drilling rod one end is connected drill bit, and the other end is connected on rig.Because the drilling depth needed is different, the length of drilling rod is also just different, when a run of steel is inadequate, is coupled together by the drilling rod of more than two or two with regard to needing.Disassembled again after boring completes, for extension drill rod during follow-up boring.
At present, in China's coal-mine, the method for attachment of drilling rod is mainly threaded connection, and namely the superior and the subordinate's drilling rod is connected by the threaded engagement of head and the tail or connected by extra screwed pipe.But Problems existing is, when rig creeps into forward, communicate larger moment of torsion to drilling rod, each drilling rod is closely engaged with between adapter sleeve, very difficult when causing dismantling threaded connecting sleeve.Usually need to knock drilling rod with strength for this reason, the threaded engagement between drilling rod and adapter sleeve is come loose, but not only waste time and energy but also very easily damage drilling rod like this, cause economic loss
Summary of the invention
The purpose of this utility model is exactly the weak point existed to solve above-mentioned technology, provides a kind of roadway support anchoring fast joint type drilling rod, simple to operate, easy to loading and unloading.
The utility model comprises: fast joint type drilling rod and U-shaped steady pin.
The utility model completes like this: design a kind of roadway support anchoring fast joint type drilling rod, drill pipe body is six side's hollow stocks, becomes male joint in drill pipe body top design, and male joint end is one section of hollow male-pipe, for connecting drill bit, screwed pipe top is a conical boss.What be connected with screwed pipe is six side's hollow stem that circumscribed circle diameter is less than drill pipe body, six square bar certain positions have an annular groove, drilling rod lower end is female joint, and female joint is six square bars that one section of circumscribed circle diameter is greater than drill pipe body, and this six square bar is directly connected with rig.Have hexagonal hole in six square bars, six side's hollow stem of this hexagonal hole and male joint fit like a glove, and hexagonal hole connects a circular port, and the screwed pipe of this circular port and the male joint of drilling rod top matches.On six square bars of female joint, symmetry has a pair rectangular recess, and rectangular recess two ends have rectangular through-hole.Drilling rod inside has central through hole, for ventilating, or water flowing.
Design a kind of U-shaped steady pin, two legs of this steady pin just can insert rectangular through-hole inside, and the length of rectangular pin two leg is consistent with the length of rectangular through-hole, and the upper width of both legs is consistent with rectangular through-hole, bottom is less than its width, has the interior pawl of a pair symmetry bottom the both legs of steady pin.
When jointed rod, the male joint of subordinate's drilling rod is inserted in the hexagonal hole in the female joint of higher level's drilling rod, the hexagonal hole of female joint matches with six square bars of male joint, can realize the transmission of circular motion between drilling rod, and the moment of torsion adopting inside and outside six side's connected modes that drilling rod is transmitted strengthens.Be inserted into by U-shaped steady pin in the rectangular through-hole of the drilling rod bottom six square bar body of rod, after inserting completely, U-shaped steady pin just can coincide with rectangular recess.U-shaped steady pin two leg is stuck on the annular groove of subordinate's fillet of tool joint pins, and interior pawl is grabbed in the base plane of higher level's drilling rod rectangular recess, achieves the constraint to drilling rod axially-movable like this.
The utility model structure is simple, and easy accessibility, compact conformation, effectively can improve connection and the dismounting speed of drilling rod, improve production efficiency, extend the application life of drilling rod.

Detailed description of the invention
Accompanying drawings detailed description of the invention of the present utility model:
Consult Fig. 1, Fig. 2, Fig. 3, the utility model adopts six side's hollow high-quality steel pipe manufacturings to become drill pipe body 4, is processed into male joint 5 and the female joint 1 of fast-connecting type in two ends of drill respectively.Male joint 5 end is the male-pipe 7 of one section of hollow, can connect drill bit, and the tip designs of screwed pipe 7 becomes a conical boss.Screwed pipe 7 bottom is six side's hollow stem that circumscribed circle diameter is less than drill pipe body 4, and six square bars have an annular groove 6 on certain position.Female joint 1 is six square bars that one section of circumscribed circle diameter is greater than drill pipe body 4, hexagonal hole 8 is had in six square bars, this hexagonal hole 8 fits like a glove with six side's hollow stem of male joint 5, and hexagonal hole 8 connects a circular port 9, and this circular port 9 matches with the screwed pipe 7 of drilling rod top male joint 5.Six square bars of female joint 1 have the rectangular recess 3 of a pair symmetry, and rectangular recess 3 two ends have rectangular through-hole 2.In drilling rod, having central through hole 10, water or gas centrally can be passed in hole when creeping into, be used for deslagging or dedusting.
Consult Fig. 4, six square bars in the male joint 5 of drilling rod coordinate completely with the hexagonal hole 8 in female joint 1, and the screwed pipe 7 in male joint 5 mates completely with the circular port 9 in female joint 1.When being connected between drilling rod, the male joint 5 of subordinate's drilling rod is inserted in the female joint 1 of higher level's drilling rod completely, now, rectangular through-hole 2 in higher level's tool joint box 1 overlaps completely with the annular groove 6 on subordinate fillet of tool joint pins 5, U-shaped steady pin 11 is inserted into completely in the rectangular through-hole 2 of the female joint 1 of higher level's drilling rod, length and the rectangular through-hole 2 in the both legs cross section of U-shaped steady pin 11 are completely the same, U-shaped steady pin 11 liang of legs are stuck on the annular groove 6 of subordinate's fillet of tool joint pins 5, interior pawl 12 is grabbed in the base plane of higher level's drilling rod rectangular recess 6, achieve the constraint to drilling rod axially-movable like this.The hexagonal hole 8 of female joint 1 matches with six square bars of male joint 5, thus achieves the transmission of circular motion between drilling rod.
Consult Fig. 5, Fig. 6, the size of U-shaped steady pin 11 both legs the first half is mated completely with rectangular through-hole 2, and the latter half is less than the width of through hole (2) on width, its objective is and prevents U-shaped steady pin 11 unstability after insertion through hole 2, affect drilling rod and connect effect.Interior pawl (12) width of U-shaped steady pin (11) bottom is greater than the width of rectangular through-hole (2), when inserting rectangular through-hole 2 can there is slight elastic deformation to adapt to rectangular through-hole 2 in U-shaped steady pin 11 liang of legs, when U-shaped steady pin 11 arrives the other end of rectangular through-hole 2, the deformation of two legs recovers, and interior pawl 12 is grabbed in the base plane of rectangular recess 3.U-shaped steady pin 11, after insertion female joint 1, can embed in rectangular recess 3 just, can be complementary with rectangular recess 3, forms complete plane structure, thus there will not be because U-shaped steady pin 11 is exposed at outside female joint 1, affect pore-forming effect.
The utility model is easy to operate, and structure is simple, and running cost is low, decreases the damage of the drilling rod caused in unloading process, effectively can improve the production efficiency in colliery, have good economic and social benefits and application value.
