Sucker rod elevator

Abstract

The invention discloses a sucker rod elevator comprising an oil pipe elevator and a fixed shaft. The fixed shaft penetrates through an axial hole of the oil pipe elevator from top to bottom. A fixed shaft clamping block is arranged in the oil pipe elevator. The fixed shaft clamping block is connected with a clamping block opening and closing power mechanism. The upper end of the fixed shaft is connected with a non-slip nut. A compression spring is arranged at the position, between the fixed shaft clamping mechanism and the non-slip nut, on the fixed shaft in a sleeving manner. The fixed shaftis of a steel pipe structure with an internal axial cavity. A supporting baffle is arranged on the lower portion of the oil pipe elevator. The lower portion of the fixed shaft is connected with a sucker rod clamping mechanism. The sucker rod elevator is high in mechanization degree, rapid clamping of the sucker rod can be achieved, and therefore the sucker rod can be conveniently screwed on and screwed off, the operator labor intensity existing in manual centering clamping operation is lowered, the work efficiency is improved, potential safety hazards of on-site operation are reduced, and safeand civilized production is ensured; and the sucker rod elevator is connected with a mechanically-driven power tong device, and therefore the automation degree is high, and the sucker rod can be automatically screwed on and screwed off.

Description

Technical field [0001] The invention relates to the technical field of oil well equipment, in particular to a sucker rod elevator. Background technique [0002] In the prior art, the sucker rod elevator is used to clamp the sucker rod, so as to realize the buckling and unfastening of the sucker rod. The sucker rod elevator in the prior art requires manual operation by multiple people and is mechanized The degree of automation is low, the operator's labor intensity is high, the work efficiency is low, and there are many hidden safety hazards in the field operation, which is not conducive to the safety of oilfield production. Summary of the invention [0003] In order to overcome the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a sucker rod elevator; the sucker rod elevator of the present invention has a high degree of mechanization by connecting a sucker rod clamping mechanism to the lower part of the fixed shaft. It can realize...
