Abstract
The utility model discloses a polished rod slip for pumping units which belongs to the technical field of other devices or components for drilling. The utility model is a clamp apparatus for an oil pumping rod used for the relative position of the pumping unit and a well head in petroleum production engineering. The utility model is composed of slip bodies, a slip, a locking screw rod and a fulcrum shaft, and the left and the right slip bodies are connected by a hinge pin. The faces facing to each other of the left and the right slip bodies are separately provided with a slope groove and the contact face of the slip and the polished rod of the pumping unit forms a circular arc camber with slip teeth, and a face facing to the circular arc camber forms a slope. The slip is installed in the slope groove of the slip body. The utility model has the advantages of simple structure, reliable clamping, anti-loose function and safe and convenient operation, bringing convenience for disassembling and assembling, adjusting position and well maintaining operation.
Description
The utility model oil-extractor polish-rod slips belongs to the miscellaneous equipment or the field of components of drilling well, and it is the sucker rod chucking device that is used for oil pumper and well head mutual alignment in a kind of petroleum production engineering.
The gripping mechanism that oil-extractor polish-rod adopts at present is two and respectively has semicircular iron plate oil pumper is embraced, tighten with nut again, the slips of this separate type, inconvenient operation in dismounting, adjustment position, workover treatment, use dangerous, the easy landing of oil-extractor polish-rod does not have the function of loosening.
The purpose of this utility model is to avoid the deficiencies in the prior art part and provides a kind of locking functions that has, oil-extractor polish-rod slips easy to use.
The purpose of this utility model reaches by following measure, it is by the slips body, slips, tie down screw and fulcrum shaft are formed, a left side, right slips body is connected by joint pin, a left side, right slips body can rotate around joint pin, fulcrum shaft is fixed on the slips body, tie down screw is enclosed within on the fulcrum shaft, tie down screw can rotate around fulcrum shaft, on a left side, the relative one side of right slips body, a surface groove is respectively arranged, slips and oil-extractor polish-rod contact surface are the circular arc camber that slip insert is arranged, one side is the inclined-plane relatively, gradient is 1:10-1:16, and slips is installed in the surface groove of slips body, and the inclined-plane of slips matches with the inclined-plane of slips body, for preventing slips slippage under free state, slips can be slided up and down in surface groove, on the slips body, be provided with a groove parallel, become dovetail shaped with the inclined-plane, also can on the slips body, be provided with a hole parallel with the inclined-plane, axially and surface groove mill logically, form a slideway, on slips, be provided with a connecting pin, sliding pin is fixedly mounted on the connecting pin, sliding pin can slide up and down in the hole, and spring supports sliding pin in the hole, and back-up block is screwed on the slips body.
The utility model is simple in structure, and reliable clamping has locking functions, and is safe and convenient to use, brings convenience for operating in dismounting, adjustment position, the workover treatment, and better practicability is arranged.
