Abstract

The utility model relates to an auxiliary tool of a beam pumping unit, in particular to a pulling-out device of a crank pin of the beam pumping unit. The technical proposal is that the auxiliary tool of the beam pumping unit is mainly composed of hanging hooks of the pulling-out device of the crank pin, a jack and a force arm of the pulling-out device, the surface of the force arm of the pulling-out device is provided with a plurality of screw holes, the hanging hooks of the pulling-out device of the crank pin and the jack are respectively fixedly connected on the screw holes; one ends of the hanging hooks of the pulling-out device of the crank pin are movably fixed on the screw holes, the other ends are provided with the hanging hooks, and a plurality of hanging hooks of the pulling-out device of the crank pin are mutually corresponding. The pulling-out device of the crank pin of the beam pumping unit has the advantages of simple structure, safe and convenient usage and low cost.

Description

Beam type oil pumping machine crank pin extractor
One, technical field:
The utility model relates to a kind of beam pumping unit instrument, particularly relates to a kind of beam type oil pumping machine crank pin extractor.
Two, background technology:
At present the beam type oil pumping machine crank pin is no matter in the repair demolition process or transfer in the stroke procedure, 2-3 people stands in the center of using sledgehammer to knock crank pins by turns on the crank crank pins is pounded out, belong to work high above the ground, the problem that this kind method exists is all to be a kind of method that wastes time and energy on the angle of safety or the angle of working environment, thereby and cause crank pins to be scrapped causing and to use using sledgehammer to knock the damage that causes the crank pins screw thread in the process of crank pins easily, one day maximum replaceable 2-4 cover crank pin in the construction of changing crank pins, and bigger, and has very serious potential safety hazard to workmen's physical demands.
Three, summary of the invention:
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, a kind of beam type oil pumping machine crank pin extractor that improves efficiency of construction and safety coefficient is provided, and has solved the crank pins thread damage and cause crank pins to be scrapped causing the problem that to use.
Its technical scheme is: mainly be made up of crank pins extractor hook, jack and the extractor arm of force, be provided with a plurality of screws on the surface of the described extractor arm of force, respectively fixedly connected crank pins extractor hook and jack on the screw; One end activity of described crank pins extractor hook is fixed on the screw, and the other end is provided with hook, and the hook of a plurality of crank pins extractor hooks is corresponding mutually.
Preferred scheme is that jack is a hydraulic jack, wherein, be fixed at the bottom of the hydraulic jack on the screw of the extractor arm of force, all concentrate on the centre of crank pins uniformly by the power that jack produced, be easy to after crank pins is stressed from the crank lining, deviate from, guarantee that the crank pins screw thread is not impaired.
The beneficial effects of the utility model are: simple in structure, safe and convenient to use, cost is low; 2-3 people just can easily finish the replacing of oil pumping machine crank pin and the construction of transferring stroke in the work progress, use this instrument that bigger raising has been arranged on efficiency of construction, the workload that can be finished 1-3 mouth individual well by two talentes in the past becomes the construction that just can finish 3-5 mouth individual well in one day;
In addition; use behind this instrument the screw thread of protection crank pins that can be in all directions to be difficult for causing the damage of crank pins; the annual workload of stroke of transferring of teams and groups is about 30 wells; a crank pins is by 3000 yuan of calculating; teams and groups just can save 20 of crank pins in 1 year nearly; add freight charges, teams and groups just can save 255000 yuan nearly.
Four, description of drawings:
Accompanying drawing 1 is a general assembly drawing of the present utility model;
Accompanying drawing 2 is vertical views of jack stand;
Accompanying drawing 3 is vertical views of the crank pins extractor arm of force;
Accompanying drawing 4 is side views of the crank pins extractor arm of force.
Five, the specific embodiment:
1-4 in conjunction with the accompanying drawings, the utility model will be further described:
Its technical scheme is: mainly by at the bottom of crank pins extractor hook 1, hydraulic jack 2, the hydraulic jack 3 and the extractor arm of force 4 form, be provided with three screws 5 on the surface of the described extractor arm of force 4, two crank pins extractor hooks 1 are threaded respectively on the screw of both sides, at the bottom of the middle screw fixed hydraulic jack 3, hydraulic jack 2 is fixed at the bottom of the hydraulic jack on 3; One end activity of described crank pins extractor hook 1 is fixed on the screw 5, and the other end is provided with hook, and the hook of two crank pins extractor hooks 1 is corresponding mutually.
Operating procedure is as follows: at first hold-down nut is unloaded, extractor is fixedly connected on the crank, note keeping hydraulic jack top end face and crank pins end face to align, hydraulic hose one end is connected hydraulic jack, one end is connected to external pressure device, tighten screw thread, guarantee no seepage and no leakage, pressure data is observed on the operating personnel limit, the limit is slowly suppressed, the principle of the hydraulic pressure of hydraulic jack all concentrates on the centre of crank pins uniformly with the power that jack produced, and is easy to deviate from from the crank lining after crank pins is stressed, guarantees that the crank pins screw thread is not impaired.
The utility model mainly is applicable to the beam pumping unit of various types of model.
