Abstract
Disclosed is a pre-stressed crank pin striker, which belongs to a production assistant tool of oil extraction in petroleum industry and mainly comprises a pre-stressed portion and a fastening portion. Besides, a striking piece of the pre-stressed portion is structured into a concentric circle, the striking piece with a lead core inside is placed on a sliding rod, and a handle is arranged on the striking piece. In addition, the fastening portion comprises a jack, a palm rope and a righting head, a post rod is disposed at the front end of a top tray of the jack, a fixed ring is arranged on the top tray, the palm rope is connected with the fixed ring, the righting head is positioned at another end of the sliding rod, the righting head is a metal circular tray, and the jack is equipped with a fixed ring. The force acted on the surface of the striker is the largest because the striker and a crank pin are on a same horizontal plane. In addition, the striking piece with the comparatively massive lead core inside is enabled to have more functions when moving on the sliding rod, thereby the force acted on the crank pin is larger, operation for disassembling the crank pin is enabled to become simpler, and the crank pin is easier to be taken out.
Description
Technical field
The utility model belongs to petroleum industry oil recovery supplement production instrument, is used to dismantle the crank-pin of beam pumping unit.
Background technology
80% belongs to mechanical oil recovery in field produces, the most of beam pumping unit that uses of mechanical oil recovery, and crank-pin is the critical piece of beam pumping unit power transmission, is that the easily worn part of oil pumper often needs to change.Optimizing when manufacturing parameter is adjusted stroke is to realize by adjusting crank-pin crank pin hole of diverse location on crank.Because beam pumping unit is long service life, again in the lowered in field environment, certainly exist phenomenons such as corrosion, aging, wearing and tearing, cause crank-pin dismounting difficulty, drop into bigger human and material resources and financial resources, replacing time lengthening, influence crude oil production, cause output to reduce.The dismounting of Crank Pin on Pumping Units is a technical barrier always.
The most of mode that adopts hammer " pounding " of dismounting crank-pin exists safety coefficient low at present, and the working time is long, damages crank-pin easily, is disassembled into shortcomings such as power is low.Existing ram has following shortcoming one: connect and lean on two screws to be connected with crank-pin, have the unsettled effect of field conduct; The 2nd: impact block does not have handle to be inconvenient to make its motion.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of prestressing force crank pins ram, to solve corrosion in the prior art crank pins lowered in field environment, aging, wearing and tearing, cause the dismounting difficulty, waste of manpower, material resources, financial resources and time, influence crude oil production, cause problems such as output reduction.
The technical scheme that its technical problem that solves the utility model adopts provides the specific purpose tool of a dismounting crank-pin, and this crank pins ram comprises prestressing force part and fastening part.The prestressing force part is made up of handle 3, impact block (4), lead for retractable pencil (5) and slide bar (6), lead for retractable pencil (5) is set in the impact block (4), impact block (4) is a concentric structure, place on the slide bar (6), handle (3) is set on the impact block (4), handle (3) flexibly connects with impact block (4), convenient pulling impact block (4); Fastening part by jack (1), coir rope (2) and set upright the head (7) form, jack (1) is taken over a business front end push rod is set, and retainer ring (8) is set on taking over a business, coir rope 2 is connected and fixed ring (8), prevents the accidental fall of ram; Set upright 7 and place slide bar (6) other end, set upright head (7) and be rosette, be spirally connected with slide bar (6).
The utlity model has following beneficial effect: because this instrument and crank-pin are to be in same horizontal plane, pretend be used on its face power also be maximum.Adding impact block is the bigger lead for retractable pencil of quality, possessed more kinetic energy when it is moved on slide bar, thereby the power that acts on the crank-pin is bigger, makes the crank-pin dismantlement work become simple to operate, easier crank-pin is taken out.This device is convenient to install, is transported and operation, uses this device can reduce labor intensity of operating staff greatly, shortens the engineering time, improves the safety coefficient height.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified:
Accompanying drawing 1 is the utility model structural representation;
1 jack, 2 coir ropes, 3 handles, 4 impact blocks, 5 lead for retractable pencils, 6 slide bars, 7 are set upright head, 8 retainer rings among the figure.
The specific embodiment
As shown in the figure; This device jack (1) is taken over a business front end push rod is set, and retainer ring (8) is set on taking over a business, and coir rope (2) is connected and fixed ring (8), prevents the accidental fall of ram; Slide bar (6) adopts solid steel pipe manufacturing; Impact block (4) is made of two concentric circles cylinders, and an amount of lead of perfusion between steel pipe two circles is worn in the middle center of circle, constitutes lead for retractable pencil (5); The same impact block of handle (3) (4) connects with movable axis; Set upright head (7) and place slide bar (6) other end, be rosette.
The effect of jack is to make slide bar produce an outside prestressing force, thereby being bump, the effect of impact block sets upright head with the loosening taking-up of crank-pin, coir rope is that prestressing force extractor lifting is fixed on the crossbeam, and handle is used for operating personnel and impact block is slided to clash into fast on slide bar and set upright head.
During on-the-spot the use, unload the locking nut of loose Crank Pin on Pumping Units earlier, the utility model be lifted on the crossbeam with coir rope, make set upright the head and jack aim at the crank-pin spindle nose respectively, the operation jack holds out against crank-pin spindle nose inboard, makes slide bar produce an outside prestressing force.Operating personnel with the hands hold handle then, make impact block keep certain strength constantly to impinge upon the head of setting upright of slide bar one end.Impact is delivered on the crank-pin by setting upright head, and the impact block that slides fast repeatedly is loosening until the crank-pin of oil pumper one side.Because the crown type wing of locking nut is greater than the crank-pin endoporus, loosening crank-pin can not drop out.Adjust the utility model, use the same method and just can unload the crank-pin of the loose other end.Lay down the locking nut at the utility model and crank-pin two ends at last, the crank-pin taking-up is got final product.Extractor is installed between two crank-pins, partly holds out against crank-pin with prestressing force earlier, dismantle with disengaging section again.
