Description
Technical Field
The utility model relates to the field of wrenches, in particular to a quick release wrench with a roller square bushing.
Background
In the drilling and workover operation process of the petroleum operation system, the roller square bushing needs to be adjusted after a square drill rod is connected with a single rotating rod at each time, the square rotating rod is placed into a rotary table bushing, because the roller square bushing has deviation with the angle fit of the rotary table, in addition, slurry is wet and smooth on the surface of the rotary table, a crow bar is usually used for being inserted into a groove where the roller is located for prying, the square rotating rod can be placed into the rotary table after being adjusted for multiple times, a driller not only wastes time and energy, but also has the risk of being damaged, meanwhile, the crow bar can possibly damage the roller, a drilling tool can not rotate in time underground, the upper and lower movement also has the risk of drilling clamping, and therefore, the fact that the roller square bushing can be placed into the rotary table rapidly and smoothly is particularly important.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problems of simple structure, convenient use, and capability of conveniently rotating the roller square bushing, effectively matching the roller square bushing with a turntable below the roller square bushing, and facilitating the quick release wrench for putting a square rotating rod into the turntable bushing.
In order to achieve the purpose, the technical scheme provided by the utility model is as follows:
quick release wrench with roller square bushing comprises a vertical pipe, wherein one side of the vertical pipe is detachably connected with an inverted L-shaped insert rod, the other side of the vertical pipe is detachably connected with a support rod, a longitudinal pull rod is fixed on the vertical pipe, the included angle between the straight part of the insert rod and the pull rod on the front side of the vertical pipe is greater than 90 degrees, and the included angle between the support rod and the pull rod on the front side of the vertical pipe is greater than 90 degrees.
Specifically, the support rod is in threaded connection with the vertical pipe, a nut is in threaded connection with the support rod in the vertical pipe, and the nut on the support rod tightly abuts against the inner edge of the vertical pipe.
Specifically, the straight portion and the riser threaded connection of inserted bar, threaded connection has the nut on the straight portion of the inserted bar in the riser, and the nut on the straight portion of inserted bar tightly supports the riser inner edge.
Specifically, the lower end of the straight part of the inserted bar is flush with the lower end of the support bar.
Compared with the prior art, the utility model has the following beneficial effects:
the roller square bushing is simple in structure and convenient to use, can conveniently rotate, can effectively match the roller square bushing with the turntable below the roller square bushing, is convenient for the square rotating rod to be put into the turntable bushing, and can effectively protect the roller square bushing in the process of rotating the square bushing.

Detailed Description
As shown in fig. 1-4, the quick release wrench with roller square bushing comprises a vertical pipe 1, wherein an inserting rod 2 with an inverted L shape can be disassembled and fixed on one side of the vertical pipe 1, the straight part of the inserting rod 2 is in threaded connection with the vertical pipe 1, a nut is in threaded connection with the straight part of the inserting rod 2 in the vertical pipe 1, the nut on the straight part of the inserting rod 2 tightly supports against the inner edge of the vertical pipe 1, a supporting rod 3 is disassembled and fixed on the other side of the vertical pipe 1, the lower end of the straight part of the inserting rod 2 is parallel to the lower end of the supporting rod 3, the supporting rod 3 is in threaded connection with the vertical pipe 1, a nut is in threaded connection with the supporting rod 3 in the vertical pipe 1, the nut on the supporting rod 3 tightly supports against the inner edge of the vertical pipe 1, a longitudinal pulling rod 4 is fixed on the vertical pipe 1, an included angle between the straight part of the inserting rod 2 and the pulling rod 4 on the front side of the vertical pipe 1 is greater than 90 degrees, and an included angle between the pulling rod 3 and the pulling rod 4 on the front side of the vertical pipe 1 is greater than 90 degrees.
The upper cover of the roller square bushing 7 is provided with a dismounting hole 5 corresponding to the roller of the roller square bushing 7, and the upper end of the roller square bushing 7 at one side of the dismounting hole 5 is provided with a nut groove 6. When needing to mend core 7 to roller side and rotating, peg graft the vertical portion of inserted bar 2 in arbitrary one disassembly hole 5 to make riser 1 be located the nut groove 6 of disassembly hole 5 one side, at this moment, the straight portion of inserted bar 2 and die-pin 3 can mend core 7 upper end contact with roller side, and then stabilize this spanner, rotate to 3 direction one sides of die-pin through making pull rod 4, can make this spanner drive roller side mend core 7 and rotate.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
