Abstract
The utility model discloses a kind of square toes syndeton of drilling machine drilling rod, comprise square toes (1), holding on square toes (1) hits dish (2), internal segment drilling rod (7), and the water-proof plate (5) on internal segment drilling rod (7); One mandrel (6) is set in internal segment drilling rod (7), mandrel (6) and internal segment drilling rod (7) inwall are connected to one, weld in the link that square toes (1) are inserted in internal segment drilling rod (7) and mandrel (6) end, the link diameter of described square toes (1) is greater than the diameter of internal segment drilling rod (7).The utility model increases by a mandrel in the internal segment drilling rod be connected with square toes, and mandrel and drilling rod are linked into an integrated entity, effectively can increase the intensity of drilling rod, prevent drilling rod place from damaging, increase the diameter of square toes link simultaneously, strengthen knowing clearly the anti-torsion performance of square toes link, thus the utility model square toes link, and drilling rod is not fragile, security performance is high.
Description
Technical field
The utility model relates to a kind of drilling rod of rotary drilling rig, specifically a kind of square toes syndeton of drilling machine drilling rod.
Background technology
Drilling rod connects drill bit in boring bar tool, in order to transmit the rod member of power.Drilling rod must can bear huge interior external pressure, distortion, bending and vibration.The square head portion of drilling rod is used for being connected with drill bit; square toes syndeton; usually be directly connected with drilling rod by square toes; when drilling rod works; square toes syndeton needs to subject larger twisting resistance; on the one hand existing square toes diameter dimension and internal segment drill pipe diameter in the same size; square toes link often can rupture; on the other hand because drilling rod is hollow structure; the drilling rod place be connected with square toes is also easy to be damaged because of stressed excessive causing; in summary, the square toes of existing drilling rod and the junction of drilling rod are easy to damage, and safety is low.
Summary of the invention
For above-mentioned prior art Problems existing, the utility model provides a kind of square toes syndeton of drilling machine drilling rod, and torsional rotation force performance is good, square toes link, and drilling rod is not fragile, and security performance is high.
To achieve these goals, the square toes syndeton of a kind of drilling machine drilling rod of the utility model, comprises square toes, and holding on square toes hits dish, internal segment drilling rod, and the water-proof plate on internal segment drilling rod; In internal segment drilling rod, arrange a mandrel, mandrel and internal segment drilling rod inwall are connected to one, and weld in the link that square toes are inserted in internal segment drilling rod and mandrel end, the link diameter of described square toes is greater than the diameter of internal segment drilling rod.
Compared with prior art, the utility model increases by a mandrel in the internal segment drilling rod be connected with square toes, and mandrel and drilling rod are linked into an integrated entity, effectively can increase the intensity of drilling rod, prevent drilling rod place from damaging, increase the diameter of square toes link simultaneously, strengthen knowing clearly the anti-torsion performance of square toes link, thus the utility model square toes link, and drilling rod is not fragile, security performance is high.
When rig works, a large amount of vibrations of generation can produce certain impact infringement to drilling rod, further, in order to reduce the infringement of vibration to drilling rod, the link of described square toes are provided with buffer.
As a kind of scheme of buffer, described buffer is led by spring and spring and forms, and described spring guiding is arranged on the link periphery of square toes; Described spring fitting is in spring guiding, and one end is hit dish and offseted with holding, and one end and water-proof plate offset.
Can according to actual condition, carry out calculating thus determine to strengthen square toes link diameter dimension, this practical property provides a kind of preferred version, and the link diameter of described square toes is 273mm, and axle diameter is 203mm.
Mandrel and internal segment drilling rod inwall need to be fixedly connected with and integrally just can reach the effect of gaining in strength, and a kind of scheme of the present utility model is, described internal segment drilling rod is corresponding with on mandrel offers pin-and-hole, is fixedly connected with by bearing pin.The another kind of scheme that the utility model provides is, described internal segment drilling rod welds with mandrel.
Further, the welding end surface in internal segment drilling rod, mandrel and square toes is formed with groove.On groove, welding operates than easier in the plane on the one hand, is conducive to the carrying out of welding, and increases the area of welding on the one hand, makes welding more firm.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
In figure: 1, square toes, 2, hold and hit dish, 3, spring, 4, spring guiding, 5, water-proof plate, 6, mandrel, 7, internal segment drilling rod.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the square toes syndeton of the utility model drilling machine drilling rod, comprises square toes 1, and holding on square toes 1 hits dish 2, internal segment drilling rod 7, and the water-proof plate 5 on internal segment drilling rod 7; In internal segment drilling rod 7, arrange a mandrel 6, mandrel 6 and internal segment drilling rod 7 inwall are connected to one, and internal segment drilling rod 7 and mandrel 6 end insert that the link of square toes 1 is interior to be welded, and the link diameter of described square toes 1 is greater than the diameter of internal segment drilling rod 7.Mandrel 6 and internal segment drilling rod 7 link into an integrated entity, and effectively increase the intensity of drilling rod, prevent drilling rod place from damaging, increase the diameter of square toes link simultaneously, and reinforcement is known clearly the anti-torsion performance of square toes link.
As shown in Figure 1, in order to vibrate the infringement to drilling rod when reducing rig work, the link of square toes 1 is provided with buffer.A kind of scheme of this buffer is made up of spring 3 and spring guiding 4, and described spring guiding 4 is arranged on the link periphery of square toes 1; Described spring 3 is arranged in spring guiding 4, and one end is hit dish 2 and offseted with holding, and one end and water-proof plate 5 offset.
According to actual condition, and through calculating, the link diameter of square toes 1 is preferably 273mm, and mandrel 6 diameter is preferably 203mm.
The scheme that mandrel is fixedly connected with internal segment drilling rod inwall provides two kinds, a kind of offers pin-and-hole internal segment drilling rod 7 is corresponding with on mandrel 6, is fixedly connected with by bearing pin.The another kind provided is that internal segment drilling rod 7 welds with mandrel 6.Wherein the first convenient disassembly, and the second need internal segment drilling rod 7 with mandrel 6 is equipped with projection and groove so that weld, the effect of welding is better, has better bonding strength.
In addition, in order to be conducive to the operation of welding, and increasing weld strength, being formed with groove at internal segment drilling rod 7, mandrel 6 with the welding end surface in square toes 1.
