Description
Technical field
The present invention relates to drilling rod used for geological prospecting, particularly to the safety device of drilling rod.
Background technology
Drilling rod is in storage and transport process, for preventing its end to be collided damage, it is generally required to install thread protecting cap.Existing thread protecting cap
With female thread, need during installation to be connected with drill rod end spiral, the most time-consuming, the screw thread of drilling rod be there is also a certain degree of
Damage；Further, when needs supplement rust preventive lubricating oil to drill rod end, in addition it is also necessary to thread protecting cap is screwed down from drilling rod, operation
Trouble.
Summary of the invention
The technical problem to be solved in the present invention is to provide the drilling rod thread protecting cap of a kind of band repairing mouth, and this thread protecting cap is directly placed on drilling rod
End, shortens the set-up time, and avoids the damage to drill rod thread completely, with repairing mouth, convenient drilling rod is supplemented profit
Lubricating oil.
In order to solve the problems referred to above, the present invention uses following scheme:
The drilling rod thread protecting cap of a kind of band repairing mouth, including thread protecting cap body, thread protecting cap body is the circle fitted mutually with drill rod end profile
Frustum, described thread protecting cap body is made up of two halves structure, including the first half caps and the second half caps, the first half caps and the second half caps
Side be connected through the hinge, opposite side be provided with can the opening of folding, the phase on the first half caps of described opening part and the second half caps
Para-position has installed repairing semi-ring, and two repairing semi-rings form repairing mouth；The corresponding periphery of the first half caps and the second half caps is provided with spiral shell
After stricture of vagina, the first half caps and the second half caps close up, locking by being installed on the retaining ring at described screw thread, retaining ring is provided with repairing
Hole, repairing hole is by oil cap encapsulation, and after the first half caps are locked by retaining ring with the second half caps, described repairing hole is the most right with repairing mouth
In.
Further improvement as technique scheme:
Described thread protecting cap body to choke, includes enlarging straight tube ring, circular cone ring and reducing straight tube ring from expansion mouth successively, first
Hinge between half cap and the second half caps is installed at enlarging straight tube ring and reducing straight tube ring；Described screw thread is arranged at outside circular cone ring
Wall close described enlarging straight tube ring.
The method have technical effect that:
The thread protecting cap of the present invention, uses the mode being directly nested with to be installed on drill rod end, it is not necessary to spiral is installed, and not only improves installation
Speed, also avoids the damage to drill rod end screw thread, arranges repairing hole and repairing mouth structure, conveniently supplements fluid to drill rod end,
Without dismantling thread protecting cap；The present invention has simple in construction, simple installation, feature that protected effect is good.
Accompanying drawing explanation
Fig. 1 is the three-dimensional structure diagram of the present invention.
Fig. 2 is the other direction view of Fig. 1.
In figure: 1, the first half caps；2, the second half caps；3, hinge；4, opening；5, screw thread；6, retaining ring；61, mend
Oilhole；7, enlarging straight tube ring；8, circular cone ring；9, reducing straight tube ring；10, repairing mouth.
Detailed description of the invention
Below in conjunction with the accompanying drawings the detailed description of the invention of the present invention is described further.
As shown in Figure 1 and Figure 2, the drilling rod thread protecting cap of the band repairing mouth of the present embodiment, including thread protecting cap body, thread protecting cap body
For the circular cone shape fitted mutually with drill rod end profile, thread protecting cap body is made up of two halves structure, including the first half caps 1 and the second half
Cap 2, the first half caps 1 are connected by hinge 3 with the side of the second half caps 2, opposite side be provided with can the opening 4 of folding, opening 4
Relative position on the first half caps 1 at place and the second half caps 2 is provided with repairing semi-ring, and two repairing semi-rings form repairing mouths 10；First
The corresponding periphery of half cap 1 and the second half caps 2 is provided with screw thread 5, the first half caps 1 and the second half caps 2-in-1 hold together after, by peace
Being loaded on the retaining ring 6 at screw thread 5 to lock, retaining ring 6 is provided with repairing hole 61, and retaining ring 6 is by the first half caps 1 and the second half
After cap 2 locking, repairing hole 61 and the lucky centering of repairing mouth 10.
As in figure 2 it is shown, thread protecting cap body from expansion mouth to choke, include enlarging straight tube ring 7, circular cone ring 8 and reducing successively
Straight tube ring 9, the hinge 3 between the first half caps 1 and the second half caps 2 is installed at enlarging straight tube ring 7 and reducing straight tube ring 9；
Screw thread 5 is arranged at the outer wall of circular cone ring 8 and near enlarging straight tube ring 7, when retaining ring 6 leans with enlarging straight tube ring 7 phase,
Repairing hole 61 and the lucky centering of repairing mouth 10.
During use, opening 4 is opened by hinge 3 by the first half caps 1 and the second half caps 2, after opening, is placed on drill rod end,
After drill rod end is fully recessed between the first half caps 1 and the second half caps 2, both is closed up, after closing up, retaining ring 6 is installed on
At screw thread 5, the first half caps 1 are locked with the second half caps 2, the lucky centering repairing in repairing hole 61 in the retaining ring 6 after locking
Mouth 10, thus thread protecting cap is stably installed on drill rod end；Whole installation is simple to operate, quick, only need to be by retaining ring during dismounting
6 screw off, and owing to installing without spiral, therefore can be used repeatedly,；When needs supplement fluid to drill rod end,
Directly injecting from repairing hole 61, repairing completes bonnet and oils cap.
