Abstract
The utility model relates to an oil pumping rod centering device. The oil pumping rod centering device is composed of two semicylindrical centering blocks. Cross longitudinal reinforcing ribs are arranged on the outer side surfaces of the semicylindrical centering blocks, and inwards concave circular arc-shaped through grooves are arranged on the inner side surfaces of the semicylindrical centering blocks. Transversal anti-shift ribs are arranged on groove surfaces. Symmetrical guide rails are arranged on two edges on the left semi parts of the inwards concave circular arc-shaped through grooves. Clamping openings are arranged on the lower surfaces of the outer end parts of the symmetrical guide rails. Grooves which are matched with the symmetrical guide rails are arranged on the combining parts of two edges of the right semi parts and the cross longitudinal reinforcing ribs. Clamping tables which are matched with the clamping openings are arranged on the outer side edges on the outer end parts of the grooves. The oil pumping rod centering device has simple structure, once pouring and forming, convenient use, abrasion resistance, and corrosion resistance. An oil rod can be centered, and the abrasion of an oil pipe is reduced.
Description
The utility model relates to a kind of oil pumping rod centering device that is used for the oil field petroleum production engineering.
The dark oil well in each oil field or its degree of depth of inclined shaft are all more than one, two kms at present, sucker rod connects very long, is easy to produce bending or crooked, though existing centralizer has certain centralizing function, but complex structure, use inconvenience, be difficult to guarantee the tram of sucker rod in oil pipe, still very big with the wearing and tearing of oil pipe, so that grind away sucker rod or oil pipe, reduce application life, stuck sometimes, cause the accident, influence the production of pumpingh well.
The deficiency that the purpose of this utility model exists at prior art and design a kind of simple in structure, easy to use, wear-resistance and anti-corrosion, can set upright the oil pumping rod centering device that beam hanger reduces the oil pipe wearing and tearing.
The purpose of this utility model is achieved in that a kind of oil pumping rod centering device, it is made of two semicylinder wiper blocks, it is characterized in that semicylinder wiper block lateral surface is provided with cross vertical ribs, medial surface is the indent arc-shaped slot pass that is complementary with sucker rod, groove face is provided with laterally anti-displacement rib, two edges, indent arc-shaped slot pass left side are provided with the guide rail of one section symmetry, guide rail is provided with bayonet socket below the outer end, indent arc-shaped slot pass right-hand part two edges and ribs binding site are provided with the groove that is complementary with guide rail, and the outer side edges of groove outer end is along being provided with the Ka Tai that is complementary with bayonet socket.
The utility model modern design, simple in structure, one-time cast-forming, easy to use, set upright effectively, can reduce oil pipe wearing and tearing, be a kind of oil pumping rod centering device of practicality.
Below in conjunction with drawings and Examples in detail the utility model is described in detail.
Fig. 1 is the utility model front view.
Fig. 2 is a wiper block schematic diagram of the present utility model.
Fig. 3 is I-I sectional view of Fig. 2.
Fig. 4 is II-II sectional view of Fig. 2.
Shown in Fig. 1-4, a kind of oil pumping rod centering device, it is made of two semicylinder wiper blocks (1), its semicylinder wiper block (1) lateral surface is provided with cross vertical ribs (2), guarantee the dynamics of setting upright of sucker rod, prevent curved incline, the sucker rod rotation torque that elimination produces because of deflection, reduce wear, medial surface is the indent arc-shaped slot pass (3) that is complementary with sucker rod, arc-shaped slot pass (3) groove face is provided with laterally anti-displacement rib (4), make to embed and take out sweat bar and its increase friction in the arc groove (3), prevent that beam hanger from producing upper and lower displacement, two edges, indent arc-shaped slot pass (3) left side are provided with the guide rail (5) of one section symmetry, guide rail (5) is provided with bayonet socket (6) below the outer end, indent arc-shaped slot pass (3) right-hand part two edges and ribs (2) binding site are provided with the groove (7) with guide rail (5) cabinet coupling, and the outer side edges of groove (7) outer end is along being provided with the Ka Tai (8) that is complementary with bayonet socket.During use a semicylinder wiper block (1) of this centralizer is installed on rod connector place or other position that need set upright, and then another semicylinder wiper block (1) swung to first wiper block (1) make up, guide rail (5) is entered in the groove (7), when two wiper blocks (1) fluid-tight engagement, Ka Tai (8) embeds and pins sucker rod in the bayonet socket (6), centralizer holds sucker rod can not throw off, and can set upright effectively, can work the cured effect of scraping again.
