Abstract
一种外套式加重杆，具体是用弹性卡头卡紧电缆的加重杆，这种加重杆由空心杆，弹性卡头，压帽组成一个靠弹性卡头卡紧的外套式加重杆。
The utility model relates to a jacket-type weighting rod, specifically a weighting rod for clamping a cable with an elastic chuck. The weighting rod is composed of a hollow rod, an elastic chuck, and a pressure cap to form a jacket-type weighting rod that is clamped by the elastic chuck.
Description
Technical field
The utility model patent relates to oil field Cut-and-thread fishing field of operation, specifically a kind of jacket-type cable weighted lever, and it is through on logging cable, to the use that cable increases the weight of, makes snap joint quickly through drilling tool water hole, can improve the speed of Cut-and-thread fishing operation.
Background technology
At present, existing weighted lever axially opens groove at metal bar, and cable is placed in groove, then with lateral pin, cable pushed down, and one of shortcoming is that pin is easily lost, two be weighted lever on cable fixing loosely, easily vibration up and down.
Summary of the invention
This patent, in order to overcome the deficiency of above-mentioned weighted lever, provides a kind of jacket-type weighted lever, and specifically with the weighted lever of elastic chuck clamping cable, this weighted lever is by hollow stem, and elastic chuck, pressure cap forms a jacket-type weighted lever by elastic chuck clamping.
This patent for the technical scheme realizing its technical problem and adopt is: in hollow stem, have cable via hole, round taper hole is had in one end of hollow stem, there is box thread the end of round taper hole, there is taper seat the end of elastic chuck, taper seat is consistent with the tapering of round taper hole, pressure cap promotes elastic chuck and moves axially, and by the interaction of round taper hole and taper seat, achieves the clamping of the utility model jacket-type weighted lever on cable and fixes.
The object of the utility model patent is: in the Cut-and-thread fishing operation process of oil field, provides more rational, practical, instrument equipment safe and reliable easily.
The beneficial effect of the utility model patent is: make Cut-and-thread fishing operation more convenient, safe and reliable, reduces risk.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model patent is further illustrated.
Fig. 1 is 3 part axial sectional structural maps of the utility model patent jacket-type weighted lever
Fig. 2 is the utility model patent jacket-type weighted lever assembling structure figure
In Fig. 1, cable via hole (1), hollow stem (2), round taper hole (3), box thread (4), taper seat (5), elastic chuck (6), cable via hole (7), male thread (8), pressure cap (9), cable via hole (10)
Detailed description of the invention
Hollow stem (2) is made cable via hole (1) slightly larger than cable size, logging cable just can be passed, round taper hole (3) is made in one end of hollow stem (2), box thread (4) is made in the end of round taper hole (3), taper seat (5) is made in the end of elastic chuck (6), consistent with the tapering of round taper hole (3), the taper seat of elastic chuck (6) (5) place is split into 3 or 4 lobes, pressure cap (9) is enclosed within elastic chuck (6), be screwed into hollow stem (2) one end with round taper hole (3), together with male thread (8) is screwed in box thread (4), pressure cap (9) is by tightening the connection of the box thread (4) of male thread (8) and hollow stem (2), promote elastic chuck (6) to move axially, under the interaction of round taper hole (3) with taper seat (5), achieve the clamping of the utility model jacket-type weighted lever on cable to fix.
