Abstract
The utility model discloses a kind of hangnail and drag for lance, comprise center-pole, center-pole two ends are respectively arranged with box cupling and spearhead, and center-pole is provided with some large lance hooks, large lance hook is distributed on center-pole shaft, and large lance hook is provided with hangnail near lance hook tip place.The utility model is by distributing with it large lance hook dragging for lance center-pole, and hangnail is set on large lance hook, add the winding probability of dragging between lance and junk, improve rope class fishing junk success rate, the secondary effectively reducing rope class junk comes off, and makes down-hole rope class fishing convenient.
Description
Technical field
The utility model belongs to oilfield salvage equipment technical field, relates to a kind of hangnail and drags for lance.
Background technology
Current oil field rope class fishing tool, mainly to drag for lance, is all field condition welding manufacture voluntarily, different, does not have fixing size, for the parameter request that lance hook size, hook distance, angle are not all fixed.In actual applications, fishing success ratio is low, easy secondary junk.
Utility model content
The purpose of this utility model is to provide a kind of hangnail and drags for lance, solves existing oil field rope class fishing junk efficiency low, and the problem of easy secondary junk.
The technical scheme that the utility model adopts is, a kind of hangnail drags for lance, comprises center-pole, center-pole two ends are respectively arranged with box cupling and spearhead, center-pole is provided with two or more large lance hooks, large lance hook is distributed on center-pole shaft, and large lance hook is provided with hangnail near lance hook tip place.
Feature of the present utility model is also,
Wherein box cupling and center-pole are threaded connection.
Wherein large lance hook and center-pole shaft are 45 ° of angles, and large lance hook tip is towards being provided with box cupling one end.
Wherein hangnail and large lance hook are 45 ° of angles, and hangnail is most advanced and sophisticated towards center-pole.
The beneficial effects of the utility model are, the utility model hangnail drags for lance, by distributing with it large lance hook dragging for lance center-pole, and hangnail is set on large lance hook, add the winding probability of dragging between lance and junk, improve rope class fishing junk success rate, the secondary effectively reducing rope class junk comes off, and makes down-hole rope class fishing convenient.
Accompanying drawing explanation
Fig. 1 is that a kind of hangnail of the utility model drags for lance structural representation.
In figure, 1. box cupling, 2. center-pole, 3. large lance hook, 4. hangnail, 5. spearhead.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
A kind of hangnail of the utility model drags for the structure of lance as shown in Figure 1, comprise center-pole 2, center-pole 2 two ends are respectively arranged with box cupling 1 and spearhead 5, center-pole 2 is provided with two or more large lance hooks 3, large lance hook 3 is distributed on center-pole 2 shaft, and large lance hook 3 is provided with hangnail 4 near lance hook tip place.
Wherein box cupling 1 and center-pole 2 are threaded connection; Large lance hook 3 is 45 ° of angles with center-pole 2 shaft, and large lance hook 3 tip is towards being provided with box cupling 1 one end; Hangnail 4 and large lance hook 3 are in 45 ° of angles, and hangnail 4 tip is towards center-pole 2.
The utility model is used for the salvaging of oil well rope class junk.Box cupling 1 is separable with center-pole 2, bar 2 one end cutting forming centered by spearhead 5.
During use, box cupling 1 is connected with beam hanger, hangnail is dragged for lance and puts into pit shaft, rotate beam hanger, thus driving hangnail to drag for lance and rotate thereupon, in rotation process, large lance hook 3 will be wound around, puncture down-hole class junk of restricting, hangnail 4 again will puncture and be wound rope class junk simultaneously, make it to come off because hangnail drags for lance rotation.Large lance hook 3 is arranged with the 45° angle of hangnail 4, not only make the intensity of dragging for lance pad increase, and make to drag for lance to the prehensile of junk and the enhancing of attached hook, junk coming off after being wound around, puncturing can be avoided, effective raising fishing success ratio, the secondary reducing in salvaging process class junk of restricting comes off.
