Description
Technical field
The present invention relates to a kind of abrasion resistant protective sleeve structure for drill rod.
Background technology
In wellbore construction, due to drilling rod High Rotation Speed in hole, and between hole wall, annular space is less, and the grinding being easy to be formed is crept into, and makes drilling rod surface abrasion serious, thus affects the working strength of drilling rod.Especially, when the geologic drilling rod of aluminium alloy material, although the drilling rod of this kind of material has lightweight, good toughness, intensity high, the nonferromagnetic substance of material is poor, and drilling rod is serious wear in use.The material of traditional this low melting point of metal surface coated aluminium alloy technology is inapplicable, therefore can only by increasing the mode of sheath mechanism, and first grinding skin, through the sheath of the increasing external diameter of cure process, reduces the grinding total amount of drilling rod.
Summary of the invention
Based on foregoing, the invention provides a kind of abrasion resistant protective sleeve structure for drill rod, solve the problem that stabilizer is wear-resisting.
The object of the invention is to be achieved through the following technical solutions:
A kind of abrasion resistant protective sleeve structure for drill rod, comprise with the drilling rod adapter sleeve be threaded and outside wearing layer, drilling rod adapter sleeve and wearing layer are all in tubular, the inner side of the front of motor of wearing layer is provided with limited block, between drilling rod adapter sleeve and wearing layer, the inner conical drogue cooperatively interacted and external conical sleeve are installed, described inner conical drogue and external conical sleeve adopt cone match, and the position that the rear portion of inner conical drogue contacts with drilling rod adapter sleeve is provided with back-up ring; The cannelure increasing frictional resistance is had inside inner conical drogue aperture.
Because aluminium drill pipe two ends are that local thickeies, the outside dimension of end is greater than body of rod outside dimension, this sheath is again be contained on the body of rod, therefore in order to the large diameter portion smoothly by body two ends, this jacket structure has five component compositions, is inner conical drogue, external conical sleeve, back-up ring, drilling rod adapter sleeve and wear-resistant sleeve respectively.
Part all adopts through heat treated Summoning material, wherein has the cannelure increasing frictional resistance inside inner conical drogue aperture, ensures there is point cantact all the time when engaging with the body of rod, ensure that the switching performance with the body of rod.
Engaging each other of the conical surface between inner conical drogue, external conical sleeve, make use of the self-locking property of the conical surface, prevents from getting loose with drilling rod, makes tapered sleeve and the body of rod turn tighter and tighter when drilling rod rotates in the direction of the clock.
The form of the semicircle card that back-up ring adopts, be convenient to install, Main Function prevents inside and outside tapered sleeve from skidding off from body of rod adapter sleeve.
Body of rod adapter sleeve is connected with adopting fine thread between wear-resistant sleeve, fully ensures the reliability connected.
Wear-resistant sleeve surface adopts Surface hardening treatment technique, strengthens the abrasion resistance on surface, and the external diameter of wear-resistant sleeve joint external diameter that the is general and body of rod is quite even slightly larger, and drilling rod can be protected like this not to be worn.
This jacket structure structure is simple, completes the mechanical interlocking mode with the body of rod by the assembling of spare and accessory parts, connects reliable, and the tricks can installed according to the length increase and decrease of the body of rod, the body of rod that simultaneously can be applicable to different bore is installed.
Accompanying drawing explanation
According to drawings and embodiments the present invention is described in further detail below.
Fig. 1 is the structural representation of a kind of abrasion resistant protective sleeve structure for drill rod of the present invention;
Detailed description of the invention
As shown in Figure 1, a kind of abrasion resistant protective sleeve structure for drill rod, comprise the drilling rod adapter sleeve 1 with being threaded and outside wearing layer 2, drilling rod adapter sleeve 1 and wearing layer 2 are all in tubular, the inner side of the front of motor of wearing layer 2 is provided with limited block 6, between drilling rod adapter sleeve 1 and wearing layer 2, install the inner conical drogue 3 and external conical sleeve 4 that cooperatively interact, described inner conical drogue 3 and external conical sleeve 4 adopt cone match, and the position that the rear portion of inner conical drogue 3 contacts with drilling rod adapter sleeve is provided with back-up ring 5; The cannelure increasing frictional resistance is had inside inner conical drogue 3 aperture.
Because aluminium drill pipe two ends are that local thickeies, the outside dimension of end is greater than body of rod outside dimension, this sheath is again be contained on the body of rod, therefore in order to the large diameter portion smoothly by body two ends, this jacket structure has five component compositions, is inner conical drogue, external conical sleeve, back-up ring, drilling rod adapter sleeve and wear-resistant sleeve respectively.
Part all adopts through heat treated Summoning material, wherein has the cannelure increasing frictional resistance inside inner conical drogue aperture, ensures there is point cantact all the time when engaging with the body of rod, ensure that the switching performance with the body of rod.
Engaging each other of the conical surface between inner conical drogue, external conical sleeve, make use of the self-locking property of the conical surface, prevents from getting loose with drilling rod, makes tapered sleeve and the body of rod turn tighter and tighter when drilling rod rotates in the direction of the clock.
The form of the semicircle card that back-up ring adopts, be convenient to install, Main Function prevents inside and outside tapered sleeve from skidding off from body of rod adapter sleeve.
Body of rod adapter sleeve is connected with adopting fine thread between wear-resistant sleeve, fully ensures the reliability connected.
Wear-resistant sleeve surface adopts Surface hardening treatment technique, strengthens the abrasion resistance on surface, and the external diameter of wear-resistant sleeve joint external diameter that the is general and body of rod is quite even slightly larger, and drilling rod can be protected like this not to be worn.
This jacket structure structure is simple, completes the mechanical interlocking mode with the body of rod by the assembling of spare and accessory parts, connects reliable, and the tricks can installed according to the length increase and decrease of the body of rod, the body of rod that simultaneously can be applicable to different bore is installed.
This sheath mechanism can be used for the installation of finished product drilling rod, increases the number of installation as required, also can select according to the size of drill pipe diameter the sheath sizes that grating is suitable.
