Abstract
The invention provides a hanging tongs tooth plate for a drill stem. The hanging tongs tooth plate comprises a wear-resistant high manganese steel tooth plate body and a plurality of wear-resistant high manganese steel teeth uniformly distributed on the tooth plate body, and corrosion-resistant alloy coatings are arranged on the surface of the tooth plate body and the surfaces of the teeth. The hanging tongs tooth plate for the drill stem has the advantages that the resistance to wear and corrosion is good, the drill stem can not be damaged, and the service life can be prolonged.
Description
Technical field
The present invention relates to a kind of drilling rod tongs dental lamina, belong to oil equipment technical field.
Background technology
Dental lamina is widely used in Type B tongs and various Power Tong (drill pipe tong, sleeve power tongs and oil pipe Power Tong) is upper, and it is the important rapid wear accessory of a class of Oil Field.Existing dental lamina is easy to wear, perishable, easily damages drilling rod, reduces application life.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, a kind of drilling rod tongs dental lamina is provided.
Drilling rod tongs dental lamina of the present invention, comprises the wear-resisting dental lamina body of potassium steel and a plurality of wear-resisting tooth of potassium steel being evenly distributed on dental lamina body, and described dental lamina body and the surface of each tooth are equipped with corrosion resisting alloy coating.
The flank of tooth of described tooth is inclined-plane or circular arc.
Drilling rod tongs dental lamina of the present invention, has following technique effect: not easy to wear, not perishable, can not damage drilling rod, and can increase the service life.
Accompanying drawing explanation
Fig. 1 is the sectional view of drilling rod tongs dental lamina of the present invention.
Wherein, 1 is the wear-resisting dental lamina body of potassium steel, and 2 is the wear-resisting tooth of potassium steel, and 3 is the corrosion resisting alloy coating of dental lamina body, the 4 corrosion resisting alloy coatings that are tooth.
The specific embodiment
As shown in Figure 1, drilling rod tongs dental lamina of the present invention, comprise the wear-resisting dental lamina body 1 of potassium steel and a plurality of wear-resisting tooth 2 of potassium steel being evenly distributed on dental lamina body, described dental lamina body is provided with corrosion resisting alloy coating 3, and the surface of each tooth is equipped with corrosion resisting alloy coating 4.The flank of tooth of described tooth is inclined-plane or circular arc.
By reference to the accompanying drawings embodiments of the present invention are described in detail above, but the invention is not restricted to above-mentioned embodiment, in the ken possessing at affiliated technical field those of ordinary skill, can also under the prerequisite that does not depart from aim of the present invention, make a variety of changes.
