Abstract
The utility model relates to a kind of multiple thread jointing type drilling rod, comprise the body of rod (1), female joint (2) and male joint (3), female joint (2) and male joint (3) are welded on the two ends of the body of rod (1) by friction welding mode; (2) have tapering external screw thread in female joint, and number of starts is greater than 1, male joint (3) have the internal thread of identical head number upper with female joint (2), tooth form and tapering.The utility model is connected by the inside and outside taper thread of the bull between male and female joint, decreases the number of turns that is threaded, improves handling speed, stable connection, reliable in quality, long service life.
Description
Technical field
The utility model relates to a kind of drilling rod, belongs to drilling machinery apparatus field, is specifically related to a kind multiple thread jointing type drilling rod.
Background technology
China's coal bed gas extraction boring or leting speeper boring, adopt screw connected drilling rod to carry out drilling construction usually.
Usually, drill rod thread coupling part adopts one start screw to connect, and in actual drilling process, the one start screw unloading number of turns is many, and workman's assembling speed is low, reduces the efficiency of handling drilling rod.
For this reason, in view of above-mentioned defect, the utility model designer passes through design and researchp with great concentration, and in conjunction with experience and the achievement of being engaged in related industry for many years, research and design has gone out a kind of multiple thread jointing type drilling rod, to overcome above-mentioned defect.
Utility model content
The one start screw unloading number of turns that the utility model mainly solves existing for prior art is many, the inefficient problem of handling drilling rod that assembling speed is low and cause, provide a kind of multiple thread jointing type drilling rod, adopt this drilling rod, the Screw assembly number of turns can be reduced when mounting distance is equal, improve handling speed, stable connection simultaneously, and screw strength is high, reliable in quality, long service life.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of multiple thread jointing type drilling rod, comprise the body of rod, female joint and male joint, wherein: female joint and male joint are welded on the two ends of the body of rod by friction welding mode, described male joint there is tapering external screw thread, described female joint has the internal thread be used in combination with male joint, and head number, the tooth form of described internal thread are identical with described external screw thread with tapering.
Optimize, above-mentioned a kind of multiple thread jointing type drilling rod, described drill rod thread tooth form is the one in triangle, trapezoidal or zigzag.
Optimize, above-mentioned a kind of multiple thread jointing type drilling rod, externally threaded number of starts is greater than 1.
Therefore, the utility model tool has the following advantages: 1, improve assembling speed: connected by the bull taper thread between male and female joint, decrease the screw thread unloading number of turns, improve assembling speed in assembling process, especially less to tapering screw thread, effect is particularly evident; 2, connection is more stable: adopt the much higher screw thread of intensity, connect more stable, simultaneously the reliable in quality of screw thread, long service life.
Accompanying drawing explanation
Fig. 1 shows the schematic diagram of multiple thread jointing type drilling rod of the prior art.
Fig. 2 shows the schematic diagram of multiple thread jointing type drilling rod of the present utility model.
Detailed description of the invention
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.In figure, the body of rod 1, female joint 2, male joint 3.
Embodiment:
As shown in Figure 2: this multiple thread jointing type drilling rod, comprises the body of rod 1, female joint 2 and male joint 3, and female joint 2 and male joint 3 are welded on the two ends of the body of rod 1 by friction welding mode; Male joint 3 there is tapering external screw thread, number of starts n > 1, female joint 2 has the internal thread of head number identical with in male joint 3, tooth form, tapering.
The utility model multiple thread tooth form can be the various structures such as triangle, trapezoidal, zigzag.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
Although more employ the body of rod 1, female joint 2 herein, term such as male joint 3 grade, does not get rid of the possibility using other term.These terms are used to be only used to describe and explain essence of the present utility model more easily; The restriction that they are construed to any one additional is all contrary with the utility model spirit.
Claims (3)
