Abstract
A kind of well head packing deflection-regulating centralizing device, comprises correction slips, hold-down nut, screw rod, support bar, feet, adjusting bolt, tuningout slips.Described support bar top is provided with correction slips, hold-down nut and screw rod in turn, and support bar bottom is provided with feet, adjusting bolt and tuningout slips in turn.The utility model possesses skills simplicity of design, function advanced person, effectively adjustment polished rod are positioned at the centre position of packing box, make to add packing work become simply, quick, also play simultaneously fix packing box when adding packing effect, polished rod can be made to be positioned at well head center, that improves packing adds speed, improve operating rate, to improve when driving a well the features such as rate, extensively in the aboveground application of oil exploitation.
Description
One, technical field
The utility model relates to oil well head supporting facility, particularly a kind of well head packing deflection-regulating centralizing device.
Two, background technology
Existing oil-field oil pumper well head, its oil-well pump polish rod, is generally just often installing not after going into the well, and therefore there is following shortcoming or deficiency: 1. wellhead polish rod secundly, and packing very easily weares and teares, and frequently need change packing; 2. due to polished rod secundly, cause adding packing work and become abnormal difficult, greatly extend the time adding packing, waste of manpower, material resources; 3. labor intensity of operating staff is large, and efficiency is low; 4. the safety factor of operating personnel is low.
Three, summary of the invention
Order of the present utility model is to provide a kind of well head packing deflection-regulating centralizing device, adopts the combining structure of support bar being installed correction slips and tuningout slips, effectively overcomes or avoids the shortcoming that exists in above-mentioned prior art or deficiency.
Well head packing deflection-regulating centralizing device described in the utility model, comprises top positive slips, hold-down nut, screw rod, support bar, feet, adjusting bolt, tuningout slips.Described support bar top is provided with top positive slips, hold-down nut and screw rod in turn, and support bar bottom is provided with feet, adjusting bolt and tuningout slips in turn.
Wherein, described hold-down nut is mounted on the top of support bar, is engaged with screw rod in hold-down nut.Described have one end of screw rod to be provided with the positive slips in top, and the other end is screw rod spanner side.Described tuningout slips is a pair symmetrical slips sheet, and its two ends are provided with adjusting bolt.
The utility model compared with prior art tool has the following advantages:
1, technical design is simple, and function is advanced;
2, effectively regulate polished rod to be positioned at the centre position of packing box, make to add packing work and become simply, fast, also play the effect fixing packing box when adding packing simultaneously;
3, polished rod can be made to be positioned at well head center, that improves packing adds speed, increases work efficiency, and improves rate when driving a well.
Four, accompanying drawing explanation
Fig. 1 is a kind of example structure schematic diagram of the present utility model;
Fig. 2 for by the A shown in Fig. 1 to structural representation;
Fig. 3 for by the B-B shown in Fig. 1 to structural representation.
Five, detailed description of the invention
Consult Fig. 1-Fig. 3, a kind of well head packing deflection-regulating centralizing device, comprise top positive slips 1, hold-down nut 2, screw rod 3, support bar 4, feet 5, adjusting bolt 6, tuningout slips 7.Support bar 4 top is provided with top positive slips 1, hold-down nut 2 and screw rod 3 in turn, and support bar 4 bottom is provided with feet 5, adjusting bolt 6 and tuningout slips 7 in turn.
Hold-down nut 2 is mounted on the top of support bar 4, is engaged with screw rod 3 in hold-down nut 2.Have one end of screw rod 3 to be provided with the positive slips 1 in top, the other end is screw rod spanner side.Tuningout slips 7 is a pair symmetrical slips sheet, and its two ends are provided with adjusting bolt 6.
During use, push up positive slips 1 and withstand polished rod, a pair slips sheet of tuningout slips 7 blocks packing box, by fastening adjustment bolt 6, polished rod top in the middle of packing box, makes polished rod be positioned at well head center, reaches the object adding packing fast.
