A positioning sleeve is arranged in the middle of the cylinder body, and torsion resistant shafts are symmetrically and oppositely arranged on two sides of the positioning sleeve through an end cover, a gasket, a sealing ring and a gland respectively; the torsion-resistant shaft is provided with a torsion-resistant shaft ball part, a torsion-resistant shaft ball head and a torsion-resistant shaft connecting part; the cylinder body and the end cover are positioned and fixed through locking nails; a wedge-shaped annular hole is formed between the end cover and the outer side of the torsion-resistant shaft; and the positioning sleeve at the position of the two anti-torsion shaft ball heads is internally provided with an inner hole of the positioning sleeve. The utility model discloses anti axial tension load can reach 600K.N, and the transmission moment of torsion can reach 4800N.M, and the during operation can realize universally, and the pivot angle can reach 7, suitably installs the flex point department at the inclined shaft, and the friction of reducible sucker rod and pipe wall inner wall to improve the service life of sucker rod.
Description
Technical field
The utility model proposes mechanical field and be used for the machinery that recovers the oil in the oil field, specifically screw pump sucker rod guide.
Background technique
Before the utility model proposes, by people such as Wang Yan a patent application about sucker rod guide has been proposed, the content of its claim is:
1, a kind of sucker rod guide, it is characterized in that: on sucker rod connecting head (1), be connected with guider shell (2), in the guider shell, be provided with guider groove (2a), guider ring cavity (2b) and guider locking closure screw thread (2c), by the guider locking closure guider screw thread locking closure (3) that has been threaded, in guider screw thread locking closure, be provided with guider screw thread locking closure negative camber ball-and-socket (3a), by the guider groove, in guider ring cavity and the formed space of guider screw thread locking closure negative camber ball-and-socket the axis of guide (4) is housed, the guider axle is provided with axis of guide plush copper (4a) near guider groove one side, and be connected with axis of guide screw rod (4c) with guider curved surface bulb (4b), axis of guide screw rod is connected with shaft joint (5), be provided with shaft joint card face (5a) in the shaft joint outside, connect and compose sucker rod guide of the present utility model with shaft joint opposite direction symmetry respectively at the guider that constitutes by the guider shell and the axis of guide.
2, guider according to claim 1 is characterized in that: the sucker rod connecting head is provided with sucker rod connecting head snap ring (1a) or sucker rod connecting head tapped hole (1b).
3, guider according to claim 1 is characterized in that: groove and axis of guide plush copper end surface shape can be rectangle, square, triangle, hexagon, octagon etc. and have the shape that the edge is faced directly.
4, guider according to claim 1 is characterized in that: the shaft joint card face of shaft joint is one group of symmetry plane or organize symmetry plane more.
The shortcoming that this sucker rod guide exists is: guide rod is installed in respectively by shaft joint in the guider shell at two ends, complex structure, and difficulty of processing is big, the manufacture cost height.
The model utility content
In order to overcome the shortcoming of existing sucker rod guide, the utility model provides a kind of screw pump sucker rod guide.This guider is by being provided with the transmission that rectangular cross section is realized rotating force between antitorque axle bulb and setting sleeve endoporus; Antitorque axle bulb is rotated between setting sleeve and end cap and is made antitorque axle realize universal rotation; Between end cap and antitorque axle, the wedge shape annular distance is set and adapts to the sucker rod desaxe; By the technical problem that pinning solves the end cap location is set between cylindrical shell and end cap.
The concrete scheme that the utility model technical solution problem is adopted is: setting sleeve is housed in the middle of in cylindrical shell, in the setting sleeve both sides by end cap, pad, seal ring and gland respectively symmetry antitorque axle is installed on the contrary; Antitorque axle is provided with antitorque axle bulb and antitorque axle bulb and antitorque axle joint; Pass through the pinning positioning and fixing at cylindrical shell and end cap; Be provided with the wedge shape annular distance between the end cap and the antitorque axle outside; Be provided with the setting sleeve endoporus in the setting sleeve of two antitorque bulb positions.
The anti-axial tension load of the utility model can reach 600K.N, and transmitting torque can reach 4800N.M, can realize universal during work, pivot angle can reach 7 °, the suitable flex point place that is installed in inclined shaft can reduce the friction of sucker rod and tube wall inwall, thereby improves the enlistment age of sucker rod.

Embodiment
According to shown in Figure 1, setting sleeve 2 is housed in the middle of in cylindrical shell 1, in the setting sleeve both sides by end cap 4, pad 6, seal ring 7 and gland 9 respectively symmetry antitorque axle 3 is installed on the contrary; Antitorque axle is provided with antitorque axle bulb 3.1 and antitorque axle bulb 3.2 and antitorque axle joint 3.3; Pass through pinning 5 positioning and fixing at cylindrical shell and end cap; Be provided with wedge shape annular distance 8 between the end cap and the antitorque axle outside; Be provided with setting sleeve endoporus 10 in the setting sleeve of two antitorque bulb positions.
Setting sleeve endoporus and antitorque axle bulb section are corresponding rectangle.
Antitorque axle bulb can be rotated in setting sleeve and end cap sphere, and antitorque axle can be in the skew of the formed pivot angle endoadaptation of wedge shape annular distance.
The antitorque axle joint that antitorque axle two ends are provided with can be connected with rod string by joint.
The utility model is in working order the time, and the antitorque axle bulb of rectangular cross section transmits rotation torque in the setting sleeve endoporus; Antitorque axle bulb can be carried out everything and be rotated between end cap and gland; Antitorque axle can be offset in the wedge shape annular distance, to adapt to the variation in sucker rod axle center.
Characteristics of the present utility model:
1, anti-axial tension load can reach 600K.N.
2, transmitting torque can reach 4800N.M.
3, when work can realize universally, and pivot angle can reach 7 °.
4, the suitable flex point place that is installed in inclined shaft can reduce the friction of sucker rod and tube wall inwall, thereby improves the enlistment age of sucker rod.
