Abstract
It the utility model is related to a kind of interior clamping device of drill collar.A kind of interior clamping device of drill collar, its structure include retainer ring, left branching rod, left skid resistant course, connection ring, right pole, right skid resistant course, it is characterised in that：Described left branching rod and right pole top are connected through a screw thread with retainer ring, there is hole in the middle part of described left branching rod and right pole, connection ring passes through hole, left branching rod and right pole can rotate around connection ring, described left skid resistant course is located at left branching rod bottom, and right skid resistant course, which is located at right pole bottom, left skid resistant course and right skid resistant course and drill collar contact surface, anti-slop serrations, it can stick into drill collar in step, reach the purpose for preventing drill collar from dropping.
Description
Technical field
The utility model belongs to Oil-Gas Well Engineering field, and in particular to a kind of interior clamping device of drill collar.
Background technology
Drill collar is one of well drilling pipe column needed to use in oil drilling.Because drill collar self structure is special in oil drilling
Point, in order to increase the pressure of the drill to drill bit, drill collar quality is typically designed must be more much bigger than other drill strings, but the general nothing of its box end
Joint thickeies.When combining bottom drill tool operation, it is necessary to drill collar be carried, lifted and is placed in brill disk, and to prevent
It falls into well and caused the accident, and processing mode is as follows at present：
Slips safe to use blocks outside drill collar, to ensure safety, reuses slips and blocks drill collar, obtains drill collar double
Protect again, prevent it from releasing and dropping.But the process is not time-consuming short, it is necessary to by sequence of operations process, in gold of very little second cun
In drilling process, it appears it is particularly very long, to reducing drilling time, it is unfavorable to reduce cost.
The content of the invention
Technical problem to be solved in the utility model is to meet drillng operation requirement enough in guarantee drill collar structural strength,
And it is not easy in the case of falling into pit shaft, designs a kind of interior clamping device of drill collar, it is intended to than traditional drill collar lifting, carries
Process is more convenient and safety, reduction drill collar drop to the probability to be caused the accident in pit shaft.
In order to solve the above technical problems, technical scheme is used by the utility model：
A kind of interior clamping device of drill collar, its structure include retainer ring, left branching rod, left skid resistant course, connection ring, right pole,
Right skid resistant course, it is characterised in that：Described left branching rod and right pole top are connected through a screw thread with retainer ring, described left branching rod
There is hole with right pole middle part, connection ring passes through hole, and left branching rod and right pole can rotate around connection ring, and described left skid resistant course is located at
Left branching rod bottom, right skid resistant course, which is located at right pole bottom, left skid resistant course and right skid resistant course and drill collar contact surface, anti-slop serrations, prevents
Drill collar drops.
By such scheme, described pole number can be 2 to 6.
Design principle of the present utility model：
In the handling process, inconvenience is unloaded in slips and safety slip installation to big quality drill collar.The utility model is new
In drill collar handling process, mainly using interior method of clamping.To ensure that pretightning force needs, above pole with lower section and not parallel, on
Fang Huiyu vertical lines have certain angle.After device puts drill collar into, fixed ring diameter is constant, constantly rotates up retainer ring mistake
Cheng Zhong, understand clamping device in gradually clamping, skid resistant course is sticked into step in drill collar, reach the purpose of safety holding drill collar.
The beneficial effects of the utility model：
A kind of interior clamping device of drill collar provided by the utility model is simple and practical, is carrying, need to only twisted in lifting process
Retainer ring, just safety holding drill collar so that drill collar is carried, lifted, is fixed conveniently, simple and convenient, saves tradition clamping dress
Operating procedure and set-up time are put, reduces drilling time, reduces drillng operation cost；The device is not easy to drop in pit shaft, subtracts
Few work accident probability of happening, reduces drillng operation cost.
Brief description of the drawings
Fig. 1 is a kind of schematic diagram of the interior clamping device of drill collar of the utility model embodiment 1.In figure：1 retainer ring, 2 is left
Pole, 3 left skid resistant courses, 4 connection rings, 5 right poles, 6 right skid resistant courses.
Embodiment
Embodiment 1
A kind of interior clamping device of drill collar, its structure include retainer ring 1, left branching rod 2, left skid resistant course 3, connection ring 4, right branch
Bar 5, right skid resistant course 6, it is characterised in that：Described left branching rod 2 and the top of right pole 5 is connected through a screw thread with retainer ring 1, described
Left branching rod 2 and the middle part of right pole 5 have hole, connection ring 4 passes through hole, and left branching rod 2 and right pole 5 can rotate around connection ring 4, described
Left skid resistant course 3 be located at the bottom of left branching rod 2, right skid resistant course 6 is located at the right bottom of pole 5, and left skid resistant course 3 and right skid resistant course 6 are with boring
Quickly contact surface has anti-slop serrations, prevents drill collar from dropping.
The undeclared part being related in the utility model is same as the prior art or is realized using prior art.
