Description
Technical field
The present invention relates to oil drill rocker field, lift convenient drilling rod pole in particular it relates to a kind of.
Background technology
Oil drill rocker is indispensable important tool in oil drilling operation, and under normal geological conditions, the oil drilling degree of depth can reach thousands of rice, Special section reach rice up to ten thousand.Generally all long for the drilling rod of oil drilling, along with the increase of drilling depth also can jointed rod.
Drilling rod is oversize then not readily transportable and stores, and is therefore generally adopted detachable drilling rod, namely adopts more piece pole to connect and compose the drilling rod of a root length, couples together, split into many poles and deposit and transport when not using during use.These poles need lifting successively to get up to install when connecting into drilling rod, and the motility of pole of the prior art lifting is enough and club shaft is propped up in easy abrasion.
Summary of the invention
The purpose of the present invention is that offer one lifts convenient drilling rod pole, arranges lifting sheath, lifting sheath offers the lifting annular groove for lifting and hole for hoist, lifts very convenient and cause damage flexibly and not to the body of rod outside the body of rod of pole.
This invention address that the problems referred to above be the technical scheme is that
Lifting convenient drilling rod pole, including the body of rod and be respectively welded at the top connection at body of rod two ends, lower contact, all offer through hole in described top connection, the body of rod, lower contact, three through holes are coaxial and the central axes of axis and the body of rod；The outer wall of described lower contact is provided with external screw thread, and the through-hole wall of top connection is provided with the female thread that the external screw thread with lower contact outer wall matches；Being welded with lifting sheath on the middle part outer wall of the described body of rod, described lifting sheath is further opened with lifting annular groove along the circumference of the body of rod, bottom and the top of lifting sheath offer hole for hoist, are provided with suspension ring in described hole for hoist.
Preferably, the bottom of described lifting sheath and top respectively offer 4 holes for hoist.
Preferably, the thickness of described lifting sheath is 10cm, and the diameter of described hole for hoist is 5-8cm.
Further, outside described top connection, it is additionally provided with the first wear-resistance protective sleeve, the bottom outer wall of the described body of rod is additionally provided with the second wear-resistance protective sleeve.
Further, described top connection, lower contact are all in hollow cylindrical, and the external diameter of lower contact is less than the external diameter of the body of rod；Described post is further opened with a ring groove, is provided with sealing ring in this annular groove.
To sum up, the invention has the beneficial effects as follows:
1, the present invention arranges lifting sheath outside the body of rod, lifting sheath arranges lifting annular groove and the hole for hoist of lifting, lifts very convenient and flexible；
2, the body of rod is not caused abrasion, the service life of the pole of guarantee when the present invention lifts.

Fig. 2 is the cross-sectional view of pole.
Labelling and corresponding parts title in accompanying drawing: the 1-body of rod；2-top connection；3-lower contact；5 first wear-resistance protective sleeves；6-the second wear-resistance protective sleeve；7-lifts sheath；71-lifts annular groove；8-sealing ring；9-hole for hoist；10-suspension ring.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the present invention is done detailed description further, but embodiments of the present invention are not limited to this.
Embodiment 1:
As shown in Figure 1, lift convenient drilling rod pole to include the body of rod 1, be welded on the top connection 2 of the body of rod 1 upper end, be welded on the lower contact 3 of the body of rod 1 lower end, through hole is all offered in described top connection 2, the body of rod 1, lower contact 3, three through holes are coaxial and the central axes of axis and the body of rod 1, it is simple to liquid flows through.
Described top connection 2, lower contact 3 are all in hollow cylindrical, and top connection 2 is identical with the external diameter of the body of rod 1, and the external diameter of the body of rod 1 is more than the external diameter of lower contact 3, and the internal diameter of lower contact 3 is identical with the internal diameter of the through hole in the body of rod 1, and the internal diameter of top connection 2 is more than the internal diameter of lower contact 3.
The outer wall of lower contact 3 is provided with external screw thread, be provided with the female thread that the external screw thread with lower contact 3 outer wall matches in the through hole of top connection 2, make many poles when being sequentially connected with the lower contact 3 of a upper pole can be threaded in the through hole of top connection 2 of next root pole.
Being welded with lifting sheath 7 on the middle part outer wall of the described body of rod 1, described lifting sheath 7 is further opened with lifting annular groove 71 along the circumference of the body of rod 1, bottom and the top of lifting sheath 7 offer hole for hoist 9, are provided with suspension ring 10 in described hole for hoist 9.In the present embodiment, the bottom of described lifting sheath 7 and top respectively offer 4 holes for hoist 9, as in figure 2 it is shown, 4 holes for hoist 9 are along the radially uniform distribution lifting sheath 7, all around four direction respectively arranges one.So, pole needs can the rope of lifting or fixture be snapped in lifting annular groove 71 when transverse shifting to lift；When needing vertically movable, it is possible to suspension hook or other fixtures are snapped in hole for hoist 9 or be connected in suspension ring 10；Any mode does not directly contact in the body of rod 1, ensures the service life of pole, and lifting is convenient to and flexibly.
Embodiment 2
On the basis of embodiment 1, the convenient drilling rod pole of lifting in the present embodiment also carries out improving as follows:
It is additionally provided with the first wear-resistance protective sleeve 5 outside described top connection 2 and protects top connection 2, the bottom outer wall of the described body of rod 1 is additionally provided with the second wear-resistance protective sleeve 6.First wear-resistance protective sleeve the 5, second wear-resistance protective sleeve 6, lifting sheath 7 adopt rich chromium cast iron to make, and its abrasion resistant effect is very good.First wear-resistance protective sleeve the 5, second wear-resistance protective sleeve 6, lifting sheath 7 thickness be 10cm, can adequately protect pole, is unlikely to again too thick；Too thick, increase the weight of pole, give transport, use and all cause bigger burden；Too thin, wear and tear too fast, reduce service life.The diameter of described hole for hoist 9 is 5-8cm, adopts 6cm, can meet use during lifting in the present embodiment, is also unlikely to the intensity of too big impact lifting sheath 7.
