Description
Technical field
It the utility model is related to drill eye blasting production equipment field, more particularly to drilling rod attachment structure.
Background technology
Underground engineering and Tunnel Engineering make excavation method with the most use be drilling and blasting method at this stage.Drilling and blasting method is to pass through brill
Hole, powder charge, the method for Blasting Excavation rock, wherein drilling is one of significant process, the fine or not direct shadow of drilling quality
Sound arrives final demolition effect.Due to being limited or in other slottings by drift section in wedge shot boring procedure
Penetration rate is considered during mode blasting boreholes, can select first to drill with short drill pipe, then connection is another in short drill pipe end
One drilling rod, so as to extension arm length, complete the follow-up boring work of blasthole.Wherein, short drill pipe and the portion of another drilling rod are connected
Divide, referred to as drilling rod attachment structure.
At present, existing drilling rod attachment structure is mainly based on screw-type, but drilling rod connection screw thread is most weak in drill string
Shakiness, crossing conference due to moment of torsion in use causes screw thread consume serious, therefore this drilling rod attachment structure general longevity
Life is shorter.Secondly, existing drilling rod attachment structure, which has, adds bolt on the basis of screw thread, holds intermediate plate, sealing ring, hoop etc. tightly
Accessory strengthens firmness, but this drilling rod attachment structure is inconvenient in installation, reduce operating efficiency.In addition, in drilling rod
Use during, due to the consume of screw thread, so as to increase the gap of drilling rod attachment structure and drill pipe section so that the brill at both ends
Bar connection is insecure, it is impossible to preferably transmits moment of torsion, or even occurs that when transfering to drilling rod after the completion of drilling what drilling rod came off shows
As.
Therefore, it is necessary to invent a kind of simpler, more reasonably drilling rod attachment structure.
The content of the invention
In order to solve the above technical problems, the purpose of this utility model is to provide a kind of simple in construction, easy for installation, connection
Firm drilling rod attachment structure.
To achieve the above object, the utility model uses following technical scheme：
Drilling rod attachment structure, it includes two drill pipe sections and adapter sleeve, and adapter sleeve links together two drill pipe sections；Two
The connecting portion of taper is respectively equipped with the opposite one end of individual drill pipe section, and the small head end of connecting portion is oppositely arranged in two drill pipe sections,
The connecting portion of corresponding two drill pipe sections is respectively equipped with the connecting hole being adapted on the adapter sleeve, and the small head end of two connecting holes is mutual
Connection insertion, the connecting portion of two drill pipe sections are socketed in corresponding to adapter sleeve on connecting hole and connect into one by locking member respectively
Body.
The small head end end face of two drill pipe section connecting portions is bonded to each other together.
Two drill pipe sections are provided with the water supply hole being coaxially disposed.
The locking member is multiple bolts being along the circumferential direction uniformly arranged, on the connecting portion and adapter sleeve of the drill pipe section
Corresponding each bolt is respectively equipped with screwed hole.
The bolt is six.
The outer wall of the adapter sleeve is cylinder.
Compared with prior art, the utility model has advantages below：
1st, the socket of connecting portion and connecting hole that two drill pipe sections and adapter sleeve pass through taper coordinates, and passes through bolt lock
Tightly, so as to which three firmly be connected, in order to transmit the moment of torsion of maximum, drilling efficiency is ensured.
The 2nd, water supply hole is set in two drill pipe sections, rig can be achieved and supplied water to drill bit, so can both reduce drill bit because with rock
The temperature of friction, dedusting of sprinkling water can be played a part of again, so as to improve bore operation environment.
3rd, the utility model is simple in construction, and required consumptive material is few, therefore purchase cost is low.In addition, only need to be by two brills during installation
Locked in the connecting portion insertion adapter sleeve of bar segment and by locking member, thus it is easy for installation.
Brief description of the drawings
The utility model is described in further details below in conjunction with the drawings and specific embodiments；
Fig. 1 is the schematic diagram of the utility model drilling rod attachment structure tiling；
Fig. 2 is A-A sectional views in Fig. 1.
Embodiment
As shown in Figure 1 or 2, the utility model includes two drill pipe sections 1 and adapter sleeve 2, and adapter sleeve 2 is by two drill pipe sections
1 links together；The connecting portion 11 of taper, and connecting portion in two drill pipe sections 1 are respectively equipped with the opposite one end of two drill pipe sections 1
11 small head end is oppositely arranged, and the connecting portion 11 of corresponding two drill pipe sections 1 is respectively equipped with the connecting hole 21 being adapted on adapter sleeve 2,
The small head end of two connecting holes 21 is connected with each other insertion, and the connecting portion 11 of two drill pipe sections 1 is socketed in corresponding to adapter sleeve 2 respectively
Linked into an integrated entity on connecting hole 21 and by locking member 4.
The small head end end face of two connecting portions 11 of drill pipe section 1 is bonded to each other together, and two drill pipe sections 1, which are provided with, coaxially to be set
The water supply hole 3 put.By setting water supply hole 3, can be achieved rig to drill bit supply water, so can both reduce drill bit because with rock frictional test
Temperature, can play a part of again sprinkle water dedusting, so as to improve bore operation environment.
Locking member 4 is multiple bolts being along the circumferential direction uniformly arranged, right on the connecting portion 11 and adapter sleeve 2 of drill pipe section 1
Each bolt is answered to be respectively equipped with screwed hole.In this example, bolt is six, in order to as much as possible lock two drill pipe sections 1.
The outer wall of adapter sleeve 2 is cylinder, depending on its size dimension is according to actual drill pipe diameter, can guarantee that and is satisfied with not
Same drill eye blasting production requirement.
In the utility model, the socket of connecting portion 11 and connecting hole 21 that two drill pipe sections 1 and adapter sleeve 2 pass through taper is matched somebody with somebody
Close, and locked by bolt, so as to which three firmly be connected, avoid the axial direction of drilling rod from coming off and radial rotary, so as to
Drilling rod can be smoothly transferred to when boring work is completed and moment of torsion caused by rig is delivered to drill bit as much as possible and is used for broken rock, from
And ensure operating efficiency.
