Abstract
The utility model relates to a drill rod thread sheath and a mounting and dismounting wrench, which comprises a thread sheath and a rocking handle. The thread sheath is arranged at the external part of a drill rod thread head. The left end of the rocking handle is connected with the right end of the thread sheath. Thread rings mated with the threads of the drill rod thread head are arranged on theinner wall of the left end of the thread sheath. The thread rings are connected with the threads on the drill rod thread head. A center hole and a side hole are arranged at the right end of the thread sheath. A driving disc is arranged at the left end of the rocking handle. A center locating wrench and a high-torque wrench are arranged on the driving disc and are mated with the left end of the thread sheath. The center locating wrench and the high-torque wrench respectively correspond to the center hole and the side hole at the right end of the thread sheath. The utility model has the advantages that the mounting and the dismounting of the thread protector of the drill rod are easy and convenient; the thread protector of the drill rod firmly and tightly tightened by using the wrench, no thread alternating is apt to be caused and the thread protector of the drill rod is protected; and the wrench is suitable for drill rod thread protectors of all kinds of specifications.
Description
Technical field
The utility model design is a kind of drilling well tool by hand, specifically a kind of special spanner that can make the drilling rod thread protector tighten, unload pine.
Background technology
In the existing wellbore construction, the thread head of drilling rod installs recoil inserts in order to prevent that collision and wearing and tearing are many additional on the drill rod thread head, and the recoil inserts installation and removal of prior art all are that the workman finishes with hand.Install stubborn often not tight with hand, at drilling rod (band drilling rod thread protector) when hanging on rig floor, the recoil inserts of drilling rod can be loosening in weight with in rotating, and causes thread alternating easily or come off, and also can damage the drilling rod screw thread when serious, the stabilizer of thread alternating is very bad in addition unloads, sometimes to beat the drilling rod thread protector with strength with sledge hammer and just can unload pine, both time-consuming, effort, uneconomical again, also can damage drilling rod silk mouth, be unfavorable for safety, civilized construction.
Summary of the invention
The utility model is a kind of drill rod thread sheath and installing/dismounting spanner, in wellbore construction, is used for fastening and unloads the special spanner of loose drilling rod thread protector.
The utility model is that a kind of drill rod thread sheath and installing/dismounting spanner are to realize in the following manner, its structure is made up of recoil inserts and rocking handle, recoil inserts is arranged on the outside of drill rod thread head; the left end of rocking handle is connected with the right-hand member of recoil inserts; the left end inwall of recoil inserts is provided with the threaded collar that matches with the drill rod thread head thread; being threaded togather on threaded collar and the drill rod thread head; the right-hand member of recoil inserts is provided with centre bore and other hole; the left end of rocking handle is provided with driving-disc; driving-disc is provided with centralized positioning spanner and the high pulling torque spanner that matches with the recoil inserts left end, and centralized positioning spanner and high pulling torque spanner be the centre bore and the other hole of the right-hand member of corresponding recoil inserts respectively.
This spanner great advantage is laborsaving, recoil inserts is set on the drill rod thread head helps protecting the drill rod thread head; Use on the rocking handle, unload that recoil inserts becomes easily, convenient; Fastened drill rod thread sheath is firm, and is not loosening, is difficult for causing thread alternating, and recoil inserts of the present utility model and dismounting spanner are applicable to the drilling well of all size drilling rod thread protector.
