Abstract
The utility model relates to an oil well packing extractor, the electric iron comprises a handle, the one end of handle is equipped with the bearing frame, the one end of a hob is connected to the bearing frame, the other end of hob is equipped with the tool bit. The utility model discloses utilizing the helical structure of packing and the helical structure of hob, under the effect of tool bit, along with the rotation of handle drive hob, taking out the packing, solved the drawback that exists when the packing is changed to the flat mouthful bottle opener of straight -bar, reduced the packing change time, reduced on -the -spot staff intensity of labour, rate when having improved oil well production has satisfied the production of oil field pumpingh well simultaneously again and has maintained the requirement.
Description
Technical field
The utility model relates to a kind of oil well packing and takes out instrument, in particular to a kind of oil well packing extractor for being taken out fast by the packing in rod-pumped well.
Background technology
Polished rod sealer is one of important parts of well on the beam wellhead equipment, and it is primarily of sealer main body, packing, gland, pressure cap composition. During oil well production, polished rod is under the effect of polished rod sealer packing, it is achieved dynamic seal, ensure that the normal production of well on the beam. But, due to the production along with oil well, polished rod and packing phase mutual friction, packing is worn, and between polished rod and packing, gap increases, and can not reach sealing effect, and gas-liquid is oozed out from gap, until bigger seepage occurs, contaminate environment, impact safety in production.
On-the-spot employee must change packing working specification according to well on the beam and carry out changing packing operation, and the conventional conventional tool that on-the-spot employee changes packing at present is straight bar flat mouth bottle opener, owing to the major design using function of straight bar flat mouth bottle opener is turn-knob screw or bolt, flat mouth bottle opener is when taking out packing and operate, seriously it is subject to the restriction of polished rod sealer receiving cavity space (ring-shaped cylinder shape), flat mouth bottle opener can not prize rapidly packing otch, thus packing can not be taken out rapidly, not only cause the operation of employee's taking-up dish to be required great effort but also time-consuming, and change the mainly taking-up at packing consuming time of overall time of packing every time, average needs 8��10 minutes, elder needs nearly half hour, rate when decreasing oil well production, add the labour intensity of on-the-spot employee.
Practical novel content
For solving the problems of the technologies described above, the purpose of this utility model is: providing a kind of oil well packing to take out instrument, it can not only reduce packing and change consuming time, reduces on-the-spot staff labor intensity, moreover it is possible to rate when improving oil well production.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of oil well packing extractor, comprises handle, and one end of described handle is provided with bearing support, and described bearing support connects one end of a screw rod, and the other end of described screw rod is provided with cutter head.
Described oil well packing extractor, described handle is cylindrical, and the periphery of the other end of described handle is provided with increasing friction force when annular knurl uses for handle.
Described oil well packing extractor, is provided with bearing in described bearing support, and in one end insertion bearing of described handle, the top and bottom of described handle and described bearing touch are respectively provided with a jump ring for limiting the axial motion of handle.
Described oil well packing extractor, the top of described step cover is provided with a bearing gland.
Compared with prior art, adopt the utility model has the advantage of of technique scheme: the utility model utilizes the spirane structure of packing and the spirane structure of screw rod, under the effect of cutter head, along with handle drives the rotation of screw rod, packing is taken out, solve the drawback existed when packing changed by straight bar flat mouth bottle opener, decrease packing replacing construction, reduce on-the-spot staff labor intensity, it is to increase rate during oil well production, meets again the production maintenance requirement of oil field pumping well simultaneously.
Accompanying drawing explanation
Fig. 1 is the utility model using state structural representation.
Description of reference numerals: 1-handle; 2-bearing gland; 3-bearing; 4-jump ring; 5-bearing support; 6-polished rod sealer; 7-packing; 8-cutter head; 9-screw rod; 10-polished rod.
Embodiment
Further describing the utility model below in conjunction with specific embodiments and the drawings, advantage and disadvantage of the present utility model will be more clear along with description.
As shown in Figure 1, for the using state structural representation of the utility model oil well packing extractor, comprising handle 1, described handle 1 is cylindrical, one end of described handle 1 is inserted in a bearing support 5, and the periphery of the other end of described handle 1 is provided with increasing friction force when annular knurl uses for handle 1.
Described bearing support 5 connects one end of a screw rod 9, and the other end of described screw rod 9 is provided with cutter head 8; Being provided with bearing 3 in described bearing support 5, in one end insertion bearing 3 of described handle 1, the top and bottom that described handle 1 contacts with described bearing 3 are respectively provided with a jump ring 4 for limiting the axial motion of handle 1; The top of described bearing support 5 is provided with a bearing gland 2.
When this device uses, utilize screw rod 9 and the spirane structure of packing 7, screw rod 9 being screwed in polished rod 10, turns clockwise handle 1 with hand, screw rod 9 and then rotates, cutter head 8 cuts the otch of packing 7, along with the rotation of this instrument, cutter head 8 gos deep into packing 7, and in rotation, packing 7 is lifted, rise, depart from polished rod sealer 6, packing 7 is all risen out.
Therefore, the utility model cutter head 8 takes out the rotation of device along with oil pumping well packing in use, and automatic seeking finds packing angular cutouts, and prolong otch incision, lift packing 7, along with further rotation, packing 7 prolongs screw rod 9 spiral-line and rises, rises, and final whole packing 7 is removed.
Therefore, as shown in the above, the utility model has the advantage of: the utility model utilizes the spirane structure of packing 7 and the spirane structure of the utility model screw rod 9, under the effect of cutter head 8, along with handle 1 drives the rotation of screw rod 9, packing 7 is taken out, solve the drawback existed when packing 7 changed by straight bar flat mouth bottle opener, decrease packing 7 replacing construction, reduce on-the-spot staff labor intensity, rate when improve oil well production, meets again the production maintenance requirement of oil field pumping well simultaneously.
Above explanation and embodiment are only exemplary, scope of the present utility model are not formed any restriction. Those skilled in the art should understand that, the details of technical solutions of the utility model and form can be modified or replace under spirit and scope of the present utility model not deviateing, but these amendments and replacing all fall in protection domain of the present utility model.
