Technical field
This utility model is related to a kind of water-through jackrod attachment structure.
Background technology
Colliery water-through jackrod when carrying out bore operation, generally according to need to connect some drilling rods carry out using with
Meet drilling depth to require.Due to needing water flowing operation, each drilling rod junctions are generally machined with limbers, and connected mode needs to meet
Following requirement：1st, bonding strength height, reliability height are to avoid Joint failure to lead to rod bit to drop in coal seam；2nd, convenient disassembly
To improve working performance；3rd, water shutoff good with avoid affect water flowing operation.
At present generally in the following ways：U-shaped card and lateral pin are used in combination and are attached positioning, outward four square bar center processing
Limbers, lateral pin adds O-ring water shutoff, inside and outside four directions cooperation transmitting torque.
There are following technical disadvantages：
When the 1st, being positioned using U-shaped card and lateral pin, need to process twice notch so that cooperation U in outer square joint opposite side
The locking position of type, rises for drilling rod simultaneously and pulls out transmission pulling force, and the presence of notch weakens the intensity of outer four directions knock-off joint, reduces drilling rod
In the life-span, so that drilling rod is easily ruptured at this section in use, bring larger economic loss；
2nd, when U-shaped card presses larger with meeting in use, because drilling rod rotation is easily deviate from, rod bit is led to be lost
Lose；
3rd, U-shaped card dismounting inconvenience, takes more, reduces working performance；
4th, lateral pin installing hole need to run through limbers, in order to prevent sluicing lateral pin from need to add O-ring sealing, not only increases into
This, and water sealing effect is not good；
5th, under equivalent specifications, it is high that square joint impact strength is not so good as six square joints.
Utility model content
The purpose of this utility model is to provide a kind of water-through jackrod attachment structure, is ensureing that water flowing is of good performance with water shutoff
Under the premise of, solve the dismounting inconvenience of traditional water-through jackrod connected mode, connection reliability is low and is susceptible to the problems such as rupture,
To improve working performance and to reduce operating cost.
For solving above-mentioned technical problem, this utility model adopts the following technical scheme that：
A kind of this utility model water-through jackrod attachment structure, including six square joints, alignment pin, stifled and drilling rod in drilling rod body
External six square joints；
It is provided with through hole on six square joint side walls in described drilling rod body；
It is provided with flat-bottom hole, on the external six square joint side walls of described drilling rod in external six square joints of described drilling rod along its length
Direction is provided with limbers；
Location hole, the described stifled through hole being fixedly installed on six square joints in described drilling rod body are provided with the wall of described stifled side
On；
Described alignment pin includes bearing pin, back-up ring, lateral pin and spring, described bearing pin is provided with vertical with described bearing pin
Stepped hole, described spring, back-up ring and lateral pin are arranged at described step in the hole composition alignment pin；
External six square joints of described drilling rod are set in six square joints in described drilling rod body, external six square joints of described drilling rod
Six square joints are sequentially inserted into stifled, through hole by alignment pin and flat-bottom hole is fixedly connected with described drilling rod body.
Further, in external six square joints of described drilling rod and drilling rod body, six aspects of six square joints are plane or have cone
The inclined-plane of degree.
Further, the upper end of described bearing pin is provided with cannelure.
Further, the longitudinal section of described bearing pin is T-shaped.
Compared with prior art, Advantageous Effects of the present utility model：
1. single bearing pin connection is simpler, more laborsaving than U-shaped card connection dismounting, improves working performance；
2. bonding strength is high, can bear bigger pulling force；
3. connect firm reliability, alignment pin is difficult for drop-off, it is to avoid lose rod bit because connecting unreliable；
4. limbers is kept completely separate with being connected bearing pin, and water shutoff is more preferable；
5. instead of U-shaped card using the connection of single bearing pin to be connected with lateral pin, reduce cost；
6. avoid the weakening to connecting portion intensity for the U-shaped card, improve drilling life of drill pipe；
7. inside and outside, six square joint mating surfaces carry slight taper, reduce fit clearance it is ensured that coordinating compactness, so as to
Transmission more high pulling torque.
