Abstract
The utility model relates to a beam-pumping unit dismounting device especially relates to a novel beam-pumping unit crank pin dismounting device. The technical scheme is as follows: the inner part of the sleeve is a pentagonal or hexagonal cavity, and the sleeve is characterized in that: four sleeve long handles (5) are arranged outside the sleeve, and the sleeve long handles (5) are movably connected with the T-shaped rotating handle (4). The utility model has the advantages that: adopt novel extracting tool, be equipped with 4 long handles on the sleeve, operating personnel only need stand on ground, rotates long handle, can easily lift off, has saved the manpower and has guaranteed safety, has both accorded with the HSE requirement, has improved the time rate of beam-pumping unit again.
Description
One, technical field:
The utility model relates to a kind of oil pumper provision for disengagement, particularly relates to the provision for disengagement of a kind of new pumping unit crank pins.
Two, background technology:
Crank pins is crucial part on the beam pumping unit, its end links with connecting rod by rolling bearing is secondary, the other end adopts taper seat structure and screw threads for fastening mode and crank body to link, thereby realized rotatablely moving of crank changed into the reciprocally swinging of walking beam horse head, and transferring power, and need frequent renewal part in the production reality, dismantle crank-pin; But adopt short and small box spanner, operating personnel must stand in and swing sledgehammer on the oil pumper and break habitually in the past, waste time and energy and dangerous rate when also influencing oil pumper.
Three, summary of the invention:
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, and providing a kind of can easily unload, and has saved manpower and has guaranteed safety, the new pumping unit crank pins provision for disengagement of rate when having improved oil pumper again.
Its technical scheme is: by inside is that the sleeve of five jiaos or hexagon cavity is formed, and it is characterized in that: four sleeve long handles (5) are housed outside sleeve, and flexibly connect at described sleeve long handle (5) and T type turning handle (4).
The beneficial effects of the utility model are: adopt novel extracting tool, 4 long handles are housed on sleeve, operating personnel only need stand in ground, rotate long handle, can easily unload, and have saved manpower and have guaranteed safety, have both met the HSE requirement, rate when having improved oil pumper again.
Four, description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
Five, the specific embodiment:
In conjunction with the accompanying drawings, the utility model will be further described:
Its technical scheme is: by inside is that the sleeve 2 of five jiaos or hexagon cavity 1 is formed, and four sleeve long handles 5 is housed outside sleeve 2, and flexibly connects by sleeve outer shaft 3 at described sleeve long handle 5 and T type turning handle 4.
Its principle is: according to lever principle, use the long handle tumbler, operating personnel only need stand in ground, rotate long handle, can easily unload, saved manpower and guaranteed safety, it is simple to have structural design, and reliable characteristics are applicable to all beam pumping units.Use this instrument, not only can reduce the generation of equipment breakdown, and for production crew has saved human and material resources, and then reduced cost of crude oil production.
Claims (2)
1, a kind of new pumping unit crank pins provision for disengagement is that the sleeve of five jiaos or hexagon cavity is formed by inside, it is characterized in that: four sleeve long handles (5) are housed outside sleeve, and flexibly connect at described sleeve long handle (5) and T type turning handle (4).
2, new pumping unit crank pins according to claim 1 provision for disengagement is characterized in that: described sleeve long handle (5) is connected by sleeve outer shaft (3) with T type turning handle (4).
