Abstract
A kind of inertia weight roller type crank-pin stripping attachment, comprising: left strut (1), adjustment barrel (2), right strut (3), weight (4), backstay (5).It is characterized in that: left strut (1), the right strut (3) of described inertia weight roller type crank-pin stripping attachment are threaded by adjustment barrel (2), the two ends of left strut (1), right strut (3) are respectively provided with an eccentric backstay (5), the length of right strut (3) is greater than the length of left strut (1), and right strut (3) is equipped with weight (4).The utility model is applicable to take out when oil field beam pumping unit adjusts stroke, crank-pin to change, easy to operate, time saving and energy saving, average operating time is 45 minutes, efficiency improves 50 percent, avoid crank-pin thread damage, well overlong time easily causes sand output well, heavy oil wells lies well and the problem such as production flow line blocking occurs to prevent oil well from stopping, and increases and produces crude output.
Description
Technical field
The utility model relates to oil-field oil pumper crank-pin extracting tool, specifically a kind of inertia weight roller type crank-pin stripping attachment.
Background technology
Current each oil field many employings beam pumping unit recovers the oil, and beam type oil pumping machine crank pin assembly is the attaching parts of crank and connecting rod, is also load-bearing and moving component simultaneously, plays a very important role.Once thread off, the situation such as fracture, very easily causing oil pumper to turn over the serious accident of machine, crude oil production and device security caused to having a strong impact on, therefore need regularly to carry out to check, safeguard, maintain, wanting there being the crank-pin assembly of damage be changed in time.Sometimes in order to meet the needs of production, require to adjust stroke to regulate manufacturing parameter, meet rational running parameter, when changing crank pins, normally a people swings sledgehammer and knocks crank pins, often occur the phenomenon that pin can not be got out, taking out of having also damages pin screw thread, causes waste.Existing patent " crank-pin removing device for bidirectional sliding-weight pumping unit ",, although achieve sliding hammer to clash into dismounting crank-pin, there is following defect in the patent No.: 200720027093.2: one is that two ends righting joint and protective disc are heavy, complex structure, difficulty of processing is large; Two be sliding hammer without handle, operation inconvenience; Three are, unlubricated groove between slide bar and sliding hammer, and friction frictional resistance is large.General replacement beam type oil pumping machine crank pin assembly is consuming time average at about 90 minutes, stops that well overlong time easily causes sand output well, heavy oil wells lies well and the problem such as production flow line blocking occurs, thus causes the loss of output and cost.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, provides a kind of inertia weight roller type crank-pin stripping attachment.
The technical solution of the utility model comprises: comprising: left strut, adjustment barrel, right strut, weight, backstay.Left strut, the right strut of described inertia weight roller type crank-pin stripping attachment are threaded by adjustment barrel, and the two ends of left strut, right strut are respectively provided with an eccentric backstay, and the length of right strut is greater than the length of left strut, and right strut is equipped with weight.
Adjustment barrel centre bore two ends in above-mentioned inertia weight roller type crank-pin stripping attachment are respectively equipped with positive and negative internal thread, and centre is provided with handle.
Weight in above-mentioned inertia weight roller type crank-pin stripping attachment is cylinder, and center is provided with through hole, two ends are provided with " ten " font groove, is arranged with four rolling in groove, centre is provided with " U " shape handle.
The beneficial effects of the utility model are: be applicable to take out when oil field beam pumping unit adjusts stroke, crank-pin to change, easy to operate, time saving and energy saving, average operating time is 45 minutes, efficiency improves 50 percent, avoid crank-pin thread damage, well overlong time easily causes sand output well, heavy oil wells lies well and the problem such as production flow line blocking occurs to prevent oil well from stopping, and increases and produces crude output.
Accompanying drawing explanation
Fig. 1-the utility model scene application broken section structural representation.
In figure, 1. left strut, 2. adjustment barrel, 201. handles, 3. right strut, 4. weight, 401. rollers, 402. handles, 5. backstay, 6. crank, 7. crank-pin; C. groove.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Shown in accompanying drawing, inertia weight roller type crank-pin stripping attachment is made up of left strut 1, adjustment barrel 2, right strut 3, weight 4, backstay 5.Left strut 1, the right strut 3 of described inertia weight roller type crank-pin stripping attachment are threaded by adjustment barrel 2, the two ends of left strut 1, right strut 3 are respectively provided with an eccentric backstay 5, the length of right strut 3 is greater than the length of left strut 1, and right strut 3 is equipped with weight 4.Described adjustment barrel 2 centre bore two ends are respectively equipped with positive and negative internal thread, and centre is provided with handle 201.Described weight 4 is cylinder, and center is provided with through hole, two ends are provided with " ten " font groove C, is arranged with four rolling 401 in groove C, centre is provided with " U " shape handle 402.
Method of operating
First, oil pumper is parked in bottom dead centre, lays down both sides crank-pin anticreep cover plate, and lay down standby cap, crown type nut; Secondly, backstay 5 is inserted in the top bolt hole of crank-pin 7, rotate the handle 201 in adjustment barrel 2, left strut 1, right strut 3 are held out against; 3rd, operating personnel hold the handle 402 of weight 4, and weight 4 is moved repeatedly, can by crank-pin 7 hit pine; 4th, loose crank-pin 7 will be hit and to screw on crown type nut, another side crank-pin 7 will be laid down for cap, crown type nut, repeat aforesaid operations.The object of the adjustment of beam pumping unit stroke, crank-pin replacing can be reached.
