Abstract
The utility model relates to a kind of slide bar type crank axle inertia hammers.It mainly solves the problems, such as existing to pound out that crank axle is time-consuming and laborious and there are security risks and axis corrosion not pound not Chu Lai and have to cut off crank axle using sledgehammer.It is characterized by: the weight (3) is nested in the middle part of slide bar (4), slide bar (4) both ends are installed with nut (2) respectively, central through hole is provided at the top of two nuts (2), two nut (2) lower parts are towards outside, respectively positive left-hand thread screw thread, two nuts (2) are threadedly coupled crank axle (1) spindle nose respectively；Weight (3) can slide on slide bar (4).The slide bar type crank axle inertia hammer, greatly reduces labor intensity, improves safe operating factor and working efficiency, reduce production cost.
Description
Technical field
The utility model relates to technical field of oil production engineering, in particular to a kind of slide bar type crank axle inertia hammer.
Background technique
In order to guarantee rod-pumped well underground liquid level in the reasonable scope, usually realized by adjusting rod-pumped well stroke,
As oil field development increasingly refines liquid level management to guarantee yield into the middle and later periods, adjust the workload of stroke also not
It is disconnected to increase.In adjusting stroke procedure, in order to take out crank axle, original mode is two people cooperation, and a people is with copper rod pad in crank
On axis spindle nose, another person is pounded with sledgehammer, and crank axle is pounded out, is had the following problems: high altitude operation, time-consuming and laborious, and is existed
Security risk；And dark soy sauce oil machine or long-term uncomfortable ginseng well, corroded between axis and axis hole, cause crank axle not pounded not Chu Lai and must not
Crank axle is not cut off, additional workload repeatedly is not only increased, and since crank axle is expensive, causes material consumption, is increased
Production cost.
Summary of the invention
Technical problem to be solved in the utility model is that existing use sledgehammer present in background technique is overcome to pound out song
Arbor is time-consuming and laborious and there are problems that security risk and axis corrosion do not pound not Chu Lai and have to cut off crank axle, and provides a kind of cunning
Rod-type crank axle inertia hammer, the slide bar type crank axle inertia hammer, greatly reduces labor intensity, improve safe operating factor and
Working efficiency reduces production cost.
The invention for solving the technical problem can reach by following technical solution: the slide bar type crank axle inertia hammer, packet
Slide bar is included, the weight of centre bore is provided with, the weight is nested in the middle part of slide bar, and slide bar both ends are installed with nut, two nuts respectively
Top is provided with central through hole, and two nut lower parts are threadedly coupled song towards outside, respectively positive left-hand thread screw thread, two nuts respectively
Arbor spindle nose；Weight can slide on slide bar.
The principle of the invention is that two sides nut and crank axle cooperate, and forms slideway with slide bar, weight slides on slideway, will not
It generates and hits deviation, be easy to have an effect.
The utility model can have the following beneficial effects: the slide bar type crank axle inertia compared with above-mentioned background technique
Hammer solves the problems, such as that axis corrosion is not pounded not Chu Lai, avoids and cut axis, ensure that the adjustment of pumping unit parameter in time, reduce production
Cost, while one man operation are easy to have an effect, greatly reduce labor intensity, improve safe operating factor and working efficiency.It is tired
Meter is applied to 4000 wells time regulating stroke of oil pumping well, avoids and cuts 400, axis, and reduction stops production loss caused by well, saves work
When take, add up wound effect 111.8 ten thousand yuan.
Detailed description of the invention
Attached drawing 1 is the structural schematic diagram of the utility model.
In figure: 1, crank axle, 2, nut, 3, weight, 4, slide bar, 5, rope sling.
Specific embodiment:
The utility model is described in further detail with reference to the accompanying drawing:
As shown in Fig. 1, the slide bar type crank axle inertia hammer, including slide bar 4, are provided with the weight 3 of centre bore, the weight
3 are nested at the middle part of slide bar 4, and 4 both ends of slide bar are installed with nut 2 respectively, are provided with central through hole at the top of two nuts 2, under two nuts 2
Portion is threadedly coupled 1 spindle nose of crank axle towards outside, respectively positive left-hand thread screw thread, two nuts 2 respectively；3 side of weight is fixed with
Lantern ring 6 is connected to rope sling 5 on lantern ring, and weight 3 can slide on slide bar 4, and diameter and 4 diameter difference of slide bar of 3 centre bore of weight are
2-4mm enables to pull and more effectively hits nut and crank axle when dragging weight；2 thread depth of nut is less than crank axle 1
The height of spindle nose, in use, 1 spindle nose of crank axle is made to be screwed into the root of nut 2, the impact force that such nut transmitting weight is hit is just
It is bigger, it can faster be easier crank axle hitting loosening.
The slide bar type crank axle inertia hammer in use, first by a nut on the crank axle of side, by weight and another
On slide bar, slide bar is inserted into first-class nut mesoporous, then other side nut is tightened on crank axle side spiro cap, passes through
It pulls and drags rope sling drive weight, hit side crank axle nut, impact force is passed to crank axle spindle nose by nut, and hitting repeatedly makes
Crank axle loosens；Then other side crank axle is hit with the same manner remove crank axle after two sides crank axle all loosens, it is real
Now adjust stroke.
The present invention forms slideway by cooperating two sides nut and crank axle, with slide bar, and weight slides on slideway, will not
It generates and hits deviation, be easy to have an effect.The slide bar type crank axle inertia hammer is applied on grand celebration seven factory's regulating stroke of oil pumping well of oil recovery,
It is accumulative to be applied to 4000 wells time regulating stroke of oil pumping well, it avoids and cuts 400, axis, reduction stops production loss caused by well, saves
Working hour expense adds up 111.8 ten thousand yuan of wound effect.
