Abstract
The utility model relates to a sucker rod anticreep hangs a section of thick bamboo. The problem that the sliding sleeve of the outer wall of the lifting barrel can not stop the sucker rod from falling out after the sucker rod is elastically deformed in the prior art is mainly solved. The method is characterized in that: the long key (7) is longitudinally additionally arranged on the outer wall of the barrel body (4), a groove (8) is longitudinally formed in the inner wall of the sliding sleeve (5), and the groove (8) in the inner wall of the sliding sleeve (5) is matched with the long key (7) in the outer wall of the barrel body (4); two handles (6) are additionally arranged on the outer wall of the sliding sleeve (5). This anti-drop bucket is hung to sucker rod, and the sliding sleeve of bucket outer wall does not go on automatically, can prevent that the sucker rod from droing, avoids the occurence of failure.
Description
Technical field
The utility model relates to a kind of Anti-releasing device for sucker rod in the oil extraction in oil field field, and particularly a kind of sucker rod anticreep hangs cylinder.
Background technology
In the oilfield downhole operation construction, most number average use sucker rod of determining hangs cylinder and carries out rountrip, its operating principle is that sucker rod is put into the cylinder that hangs that is complementary, hang drum outer wall the annulus that stops sucker rod is arranged, annulus can slide up and down hanging drum outer wall, after sucker rod enters and hangs cylinder, annulus slided into hang a lower curtate, finish the effect that stops that sucker rod drops out.But in the changeable situation of underground construction operation, particularly after sucker rod generation elastic deformation, annulus can be pushed up and hang a top, sucker rod drops out from hang cylinder, its catch ring does not often have the effect that stops sucker rod, causes the accident of rod fall to occur.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the sliding sleeve that hangs drum outer wall after sucker rod generation elastic deformation that exists in the background technology can not stop the problem that sucker rod drops out, and provide a kind of sucker rod anticreep to hang cylinder, this sucker rod anticreep hangs cylinder, the sliding sleeve that hangs drum outer wall does not carry out automatically up, can prevent that sucker rod from coming off, avoid accident to occur.
The invention for solving the technical problem can reach by following technical solution: this sucker rod anticreep hangs cylinder and comprises cylindrical shell, sliding sleeve, cylindrical shell top connects lock nut and drop handle by the drop handle axle, described cylinder body outer wall vertically installs long key additional, the sliding sleeve inwall vertically has groove, and the groove of sliding sleeve inwall cooperates with the long key of cylinder body outer wall; The sliding sleeve outer wall installs two handles additional.
The utility model is compared with the above-mentioned background technology can have following beneficial effect: this sucker rod anticreep hangs cylinder owing to adopt said structure, can reduce drop from the hang cylinder generation of accident of in construction sucker rod, has greatly improved the safety of construction.Easy and simple to handle easy-to-use, use manpower and material resources sparingly, reduce the tremendous economic loss that repeats operation.
Description of drawings:
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is lateral views of Fig. 1;
Accompanying drawing 3 are Fig. 2 along A-A to the structure sectional view;
Accompanying drawing 4 are Fig. 2 along B-B to the structure sectional view.
Among the figure: 1-drop handle, 2-lock nut, 3-drop handle axle, 4-cylindrical shell, 5-sliding sleeve, 6-handle, the long key of 7-, 8-groove, 9-positive stop key.
The specific embodiment:
Below in conjunction with accompanying drawing will the utility model is described in further detail:
Accompanying drawing 1 is in conjunction with Fig. 2, Fig. 3, shown in Figure 4, and this sucker rod anticreep hangs cylinder and comprises cylindrical shell 4, sliding sleeve 5, and cylindrical shell 4 connects lock nut 2 and drop handle 1 by drop handle axle 3; Described cylindrical shell 4 outer walls vertically install long key 7 additional, and sliding sleeve 5 inwalls have groove 8; The groove 8 of sliding sleeve 5 inwalls cooperates with the long key 7 of cylindrical shell 4 outer walls; The groove 8 one side limited location keys 9 of sliding sleeve 5 inwalls; Sliding sleeve 5 outer walls install two handles 6 additional, conveniently make annulus horizontal and vertical in stupefied interior activity; Described long key 7 wide 10mm, high 2.5mm; Described groove 8 wide 16mm, groove depth 3mm.
When this sucker rod anticreep hangs the cylinder use; vertically install long key additional at cylinder body outer wall; the wide 10mm of long key; high 2.5mm; at the sliding sleeve inwall fluting of cylinder body outer wall, groove width 16mm, groove depth 3mm; and install positive stop key additional at sliding sleeve fluting position; making sliding sleeve arrive the bottom can be freely laterally movable, vertically can only be movable along the track that installs long key additional, can not scurry out in long key; slide over like this under operating personnel's the operation and in the track of long key, slidably reciprocate; as not having operating personnel's operation, it is up and down that this sliding sleeve can not hang drum outer wall at sucker rod, when sucker rod generation elastic deformation; do not having under operating personnel operate, make sliding sleeve can not on move.Sucker rod can not drop out from hang cylinder like this.Be the handled easily personnel operation, install two handles additional at the sliding sleeve outer wall, conveniently make sliding sleeve movable, this operation improving is extremely easy, need only operating personnel at horizontal movable sliding sleeve, other and normal operating are just the same.Improve safety in utilization, reduced the tremendous economic loss that repeats operation.
