Abstract
This utility model is a kind of beam-pumping unit polish rod elevator, for the polished rod of rod-pumped well.This optical-rod clamp includes the first card body, the second card body and slip dog, first card body and the second card body be symmetrically installed, wherein heart hole both sides be equipped with dental lamina sliding cavity, chute and dental lamina sliding cavity insertion, the sliding pin on slip dog can be slided in chute, and retaining mechanism is connected with slip dog；First card body and second card body one end are hinged by the pivot pin in through hole, the other end is fixed with bolt by fixed ear.Polished rod clamping screw is turned, two slip dogs can be made to lock tighter and tighter with polished rod.While stubborn polished rod clamping screw, it is ensured that bolt will not be moved up and down, uniform force, it is to avoid pound and strike the polished rod that the polished rod unbalance stress of slip dog generation causes and come off problem.This utility model is easy to assembling, small volume, compact conformation, is convenient for carrying.
Description
Technical field
This utility model is related to the aid of petroleum industry rod-pumped well, particularly a kind of beam-pumping unit polish rod elevator, uses
On the polished rod of rod-pumped well.
Background technology
In the production producing well in oil field, great majority adopt sucker rod pumping, and this mode of production is will by down-hole string
Surface power drive passes to the oil well pump of down-hole, and the top of down-hole string is polished rod.In production management, it is often necessary on ground
Polished rod is blocked with optical-rod clamp, carry out the production operation of correlation.At present, the optical-rod clamp used in the production of oil field is by this
Body, slip insert piece, fastening bolt composition, body and slip insert piece partial installation.Its operation principle is：First by the two panels of body point
Set outside the circumference of polished rod, two parts of body are connected with fastening bolt；By two panels slip insert piece around polished rod circumference
It is put in the bellmouth of body, slip insert piece is pounded downwards with hammer and light is locked when body exposes outside 10mm to slip insert piece tightly
Bar.This mode of operation not only operates inconvenience, is also easy to damage polished rod.
The content of the invention
The purpose of this utility model is to provide a kind of beam-pumping unit polish rod elevator, to solve defect of the prior art, is made
Which can protect polished rod, and easy to operate, improve work efficiency, protect production equipment.
For achieving the above object, technical solution of the present utility model is：A kind of beam-pumping unit polish rod elevator includes first
Card body, the second card body and slip dog, the first card body and the second card body be symmetrically installed, wherein heart hole both sides be equipped with dental lamina cunning
Dynamic chamber, chute and dental lamina sliding cavity insertion, the sliding pin on slip dog can be slided in chute, retaining mechanism and slip dog
Connection；First card body and second card body one end are hinged by the pivot pin in through hole, the other end is fixed with bolt by fixed ear.
Compared with prior art, the beneficial effects of the utility model are：This utility model is mounted in due to retainer ring
The outside of one card body and the second card body, bolt are installed with retainer ring activity, so when the first card body and the second card body are by fixing
After ear locking, polished rod clamping screw is turned, the slide block of its bolt front end and the shifting chute wedge-like engagement of slip dog make two cards
Watt dental lamina is locked tighter and tighter with polished rod.While stubborn polished rod clamping screw, it is ensured that bolt will not be moved up and down, uniform force, from
And ensure that the use of bolt will not be limited in narrow and small work space.Avoid and pound the polished rod stress for striking slip dog generation
The polished rod that inequality is caused comes off problem.The fit structure of the first card body and second card body one end radial type is easy to assemble, small volume,
Compact conformation, it is convenient for carrying, with significant using effect and using value.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
