Abstract
The utility model relates to a polished rod slip for an oil pumping machine, which belongs to the field of other devices or components for well drilling. The utility model is an oil pumping rod clamping device used for the relative position of an oil pumping machine and a well head in the oil production engineering. The utility model is composed of slip bodies, a locking screw rod, and a hinge pin, wherein, the locking screw rod penetrates through a hole on one slip body, an annular groove in which a retaining ring is arranged on the locking screw rod, and a screw hole matched with the locking screw rod is arranged on the other slip body. The utility model has the advantages of simple structure, reliable clamping performance and safe and convenient operation and the anti-loosing function and brings convenience for the operation in disassembly and assembly, position regulation and well repair work.
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 that two slips bodies that separate are embraced oil-extractor polish-rod, tighten with lock bolt again, the slips body separates with lock bolt, the slips of this separate type, inconvenient operation in dismounting, adjustment position, workover treatment, use dangerously, need two people operation, work high above the ground is just more inconvenient.
The purpose of this utility model is to avoid the deficiencies in the prior art part and a kind of monolithic is provided, easy accessibility, oil-extractor polish-rod slips efficiently.
The purpose of this utility model reaches by following measure, it is by the slips body, tie down screw and hinge pin are formed, a left side, right slips body is connected by joint pin, a left side, right slips body can rotate around joint pin, tie down screw passes a hole on the slips body, one ring-shaped groove is arranged on tie down screw, be provided with back-up ring in ring-shaped groove, on another slips body the screw that matches with tie down screw arranged, tie down screw passes the hole on the slips body, back-up ring is set in the ring-shaped groove on tie down screw, tie down screw can not be thrown off from the slips body, and tie down screw is become one when the mounting or dismounting slips, and all parts of slips are connected as a single entity, become integral body, do not have separation member, when operation, a people just can realize convenient and swift mounting or dismounting.For the motion that makes tie down screw is not subjected to the influence of back-up ring, on hole relative on the slips body, be provided with interior step with back-up ring, the mobile space of tie down screw is strengthened, use convenient.
The utility model is simple in structure, and reliable clamping is safe and convenient to use, brings convenience for operating in dismounting, adjustment position, the workover treatment, and better practicability is arranged.
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with accompanying drawing the utility model is further described.
As shown in drawings, the utility model is by slips body (1), (5), tie down screw (2), joint pin (4), back-up ring (3) is formed, a left side, right slips body (1), (5) connect by joint pin (4), become monolithic construction, a left side, right slips body (1), (5) can rotate around joint pin (4), tie down screw (2) passes the hole on the left slips body (1), on tie down screw (2), a ring-shaped groove is arranged, in ring-shaped groove, be provided with back-up ring (3), the screw that matches with tie down screw (2) is arranged on right slips body (5), tie down screw (2) passes the hole on the left slips body, upward in the ring-shaped groove back-up ring (3) is set at tie down screw (2), tie down screw can not be thrown off from the slips body, for the motion that makes tie down screw (2) is not subjected to the influence of back-up ring (3), on hole relative on the slips body, be provided with interior step (6) with back-up ring, the mobile space of tie down screw is strengthened, tie down screw becomes one when the mounting or dismounting slips, all parts of slips are connected as a single entity, and become integral body, do not have separation member, when operation, one people just can realize convenient and swift mounting or dismounting, during use, tie down screw is passed hole on the left slips body, back-up ring is set in the ring-shaped groove on tie down screw, rotate left slips body, tie down screw is screwed in screw on the left slips body, oil-extractor polish-rod is clamped.
