Abstract
The invention discloses a drill rod connecting hand, which comprises a tubular metal rigid body, wherein an alloy transition layer is arranged on an external surface of the metal rigid body; and a single-crystal diamond and alloy mixed working layer is arranged outside the alloy transition layer. The drill rod connecting hand has the advantages of good rigidity, abrasion resistance and long service life, and is applicable to the industries of geological exploration and well drilling and matched with a drill rod.
Description
Technical field
The present invention relates to a kind of being applied to takes over the matching used drilling rod of drilling rod in the industries such as geological prospecting, drilling well.
Background technology
Drilling rod mainly be used for industries such as geological prospecting, drilling well connect drill bit, in order to the rod member of transferring power; And the drilling rod catcher mainly is to be sleeved on the device that drilling rod is used for jointed rod outward.At present, the drilling rod that is used on the drilling rod is taken over the metal rigid body that comprises tubulose, this metal rigid body is through Overheating Treatment, carbon processing etc. are to guarantee its rigidity, and the Buddha's warrior attendant body is coated on outside the metal rigid body by the mode of electroplating, the drilling rod catcher that obtains by above-mentioned processing is with after drilling rod is connected, in the course of the work, if run into ground condition complicated situation, then do not have very strong abrasion resistance, influenced the operating efficiency of drilling rod, also make simultaneously the drilling rod low precision, in case the Buddha's warrior attendant body that is electroplated onto on the drilling rod catcher is worn, the metal rigid body of drilling rod catcher then damages easily, thereby causes drill rod abrasion to be scrapped, at above-mentioned shortcoming, be necessary to make improvement.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of good rigidly, wear-resistant, long service life, make the drilling rod working stability, the effective drilling rod catcher of drilling rod protection.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of drilling rod is taken over, and comprises the metal rigid body of tubulose, and described metal rigid body external surface is provided with the alloy transition layer, is provided with single-crystal diamond and alloy hybrid working layer outside the alloy transition layer.
Wherein, described metal rigid body external surface has annular recess, and described single-crystal diamond and alloy hybrid working layer pass through alloy transition layer secure bond in the annular recess of metal rigid body external surface.
The invention has the beneficial effects as follows: the alloy transition layer is set and single-crystal diamond is set and alloy hybrid working layer outside the alloy transition layer by metal rigid body external surface at the drilling rod catcher; Adopt said structure and material to improve the rigidity and the application life of drill bit catcher greatly, even also not easy to wear under ground condition complex operating environment, one side has guaranteed the stability of drilling rod work, also drilling rod has been played the certain protection effect simultaneously.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present invention.
The specific embodiment
With reference to Fig. 1.A kind of drilling rod is taken over, and comprises the metal rigid body 1 of tubulose, and described metal rigid body 1 external surface is provided with alloy transition layer 2, is provided with single-crystal diamond and alloy hybrid working layer 3 outside alloy transition layer 2.
Wherein, described metal rigid body 1 external surface has annular recess, and described single-crystal diamond and alloy hybrid working layer 3 pass through alloy transition layer 2 secure bond in the annular recess of metal rigid body 1 external surface.
The present invention is provided with alloy transition layer 2 and single-crystal diamond is set and alloy hybrid working layer 3 outside alloy transition layer 2 by metal rigid body 1 external surface at the drilling rod catcher; Adopt said structure and material to improve the rigidity and the application life of drill bit catcher greatly, even also not easy to wear under ground condition complex operating environment, one side has guaranteed the stability of drilling rod work, also drilling rod has been played the certain protection effect simultaneously.
The present invention have good rigidly, wear-resistant, long service life advantage, be a kind of being applied in the industries such as geological prospecting, drilling well and the matching used drilling rod catcher of drilling rod.
Claims (2)
