Abstract

The utility model provides an antitheft sucker rod elevator, which mainly solves the problems of easy been stolen and easy loose of the existing pumping rod clip. The antitheft sucker rod elevator is characterized in that the upper end face of the boss of a base (5) is provided with a counter bore (7) which is provided with the screw bolts (6) inside; the side wall of the upper end of the base (5), which is corresponded to the upper end of the screw bolt (6), is provided with the screw holes (9), and the inner part of the screw hole (9) is provided with the screws (8); a lock sleeve (10) is fixed on the side wall of the base (5) out of the screw hole (9), and a cylinder lock core (4) connected with the screws (8) is fixed in the lock sleeve (10). The antitheft sucker rod elevator has the advantages of antitheft and loose prevention.

Description

Antitheft sucker rod clamp

Technical field:

The utility model relates to used instrument in the petroleum production engineering field, oil field, belongs to a kind of antitheft sucker rod clamp.

Background technology:

In oil-field oil pumper oil recovery manufacturing process, sucker rod is fixed on by the sucker rod clamp about the polished rod eye of oil pumper, plays fixing and position-limiting action.And present employed sucker rod clamp owing to do not have antitheft, loosing-proof device on the clamp, makes clamp easily stolen, easily loosening, cause sucker rod to come off, cause down-hole accident when serious, increased maintenance load, reduce production efficiency, influenced ordinary production.

The utility model content:

In order to overcome existing sucker rod clamp deficiency easily stolen, that easily become flexible, the utility model provides a kind of antitheft sucker rod clamp, and this antitheft sucker rod clamp has antitheft, anti-loosening characteristics.

The technical scheme that the utility model adopted is: this antitheft sucker rod clamp comprises lower clip, guide pillar and base, be installed with guide pillar in the through hole at clamp two ends and link to each other with base, the base boss upper surface has the counterbore that is built-in with bolt, have the screwed hole of built-in screw on the sidewall of base upper end and bolt upper end corresponding position, the fixing lock cylinder that links to each other with screw in the intrinsic lock tube on the screwed hole outer base sidewall, lock tube.

The beneficial effects of the utility model are: this antitheft sucker rod clamp is owing to have the screwed hole of built-in screw with bolt upper end corresponding position on the sidewall of base boss upper end, intrinsic lock tube on the screwed hole outer base sidewall, the fixing lock cylinder that links to each other with screw in the lock tube, after with key lock, box spanner can't enter, thief can't be stolen, and has realized antitheft purpose; Block bolt head mutually because of screw simultaneously, make bolt to rotate, avoid clamp to become flexible and cause sucker rod to come off, reduced maintenance load, guaranteed safe ordinary production, improved production efficiency.

The specific embodiment:

The utility model is described in further detail below in conjunction with accompanying drawing:

As shown in Figure 1, this antitheft sucker rod clamp comprises clamp (1,2), guide pillar 3 and base 5, be installed with guide pillar 3 in the through hole at clamp (1,2) two ends and link to each other with base 5, base 5 boss upper surfaces have counterbore 7 between two parties, counterbore 7 is built-in with bolt 6, bolt 6 lower ends touch mutually with clamp 1, can adjust the degree of tightness of clamp (1,2) by bolt 6; Have tapped through hole 9 on one sidewall of base 5 boss upper ends with on the sidewall of bolt 6 upper end corresponding positions, screwed hole 9 built-in screws 8, screw 8 can touch mutually with bolt 6 upper ends, bolt 6 can be blocked by screw 8; Intrinsic lock tube 10 on screwed hole 9 outer base 5 sidewalls, lock tube 10 is built-in with lock cylinder 4, and lock core 4 lower end tongue pieces link to each other with the opening of screw 8 upper ends, drive screw 8 by rotary locking cylinder 4 and move, and make screw 8 block bolt 6, have realized antitheft purpose.

During actual the use, the same with existing clamp, just installing, by bolt 6 being blocked, can realize antitheft and anti-loosening purpose with key rotary locking cylinder 4.

Claims

1, a kind of antitheft sucker rod clamp, comprise clamp (1,2), guide pillar (3) and base (5), clamp (1,2) be installed with guide pillar (3) and link to each other in the through hole at two ends with base (5), it is characterized in that: base (5) boss upper surface has the counterbore (7) that is built-in with bolt (6), have the screwed hole (9) of built-in screw (8) on the sidewall of base (5) upper end and bolt (6) upper end corresponding position, the fixing lock cylinder (4) that links to each other with screw (8) in the intrinsic lock tube (10) on screwed hole (9) outer base (5) sidewall, lock tube (10).
