Abstract
The utility model provides a drill stem for oil drilling, in particular to a drill stem for a revolution bored pile. The utility model comprises a primary drill stem and a secondary drill stem which are of hollow hexagon structure and are used together. The primary drill stem main body is 1m long and the secondary drill stem is 3 to 4m long. The utility model changes the primary drill stem and the secondary drill stem of the prior art into the coordinated hollow hexagon structure. The primary drill stem and the secondary drill stem matches with each other, which solves repetitive drill hoist problem, reduces the friction of the repetitive drill hoist to hole wall and the possibility of hole collapse and facilitates hoist use. The actuality of the prior art that only the primary drill stem transfers power is changed; each segment of drill stem of the utility model can transfer power; the operation is safe and the production efficiency is high.
Description
Technical field
The utility model relates to a kind of oil drilling drilling rod of usefulness already, specifically rotatory boring castinplace pile drilling rod.
Background technology
Existing drilling rod is divided into main and auxiliary drilling rod, and main and auxiliary drilling rod is used.Main drilling rod is the Long Hexagon drilling rod, and auxilliary drilling rod is the circular hollow drilling rod, and general main run of steel is between 4-6m, and auxilliary drilling rod is installed on the main drilling rod.Because both structure difference, during work, increase drilling rod all needs and will promote behind the main rod boring again at every turn, and promoting has repeatedly increased the disturbance to hole wall of stroke that drilling rod promotes and drill bit, and labor productivity is lower.The revolute function of drilling rod is the bond realization of the hexagonal hole of the rotary disk bottom rig to main drilling rod, owing to repeatedly lift drilling rod, drill bit is big to the frictional force of hole wall, easily causes the hole of collapsing.And time spent master drilling rod will not hang to hang and leans on rig by wire rope, and it is heavy, dangerous that lifting, operation all show, and injury accident takes place easily.
Summary of the invention
Goal of the invention of the present utility model is at prior art drilling rod heaviness, uses unsafe deficiency, a kind of hexagonal structure that complements one another that main and auxiliary drilling rod is changed into is provided, the length of main drilling rod shortens, and manipulates safe, short and light rotatory boring castinplace pile drilling rod.
Realize the foregoing invention purpose by the following technical solutions: a kind of rotatory boring castinplace pile drilling rod, comprise main drilling rod and auxilliary drilling rod, described main and auxiliary drilling rod is the hexagonal structure of the hollow used of complementing one another, long 1 meter of wherein main drilling rod is assisted the long 3-4 rice of drilling rod.
Adopt technique scheme, compared with prior art, the utility model changes the auxilliary drilling rod of the circular hollow of prior art into the hexagonal structure hollow drill, main drilling rod changes and assists the supporting hollow hexagonal structure of drilling rod into, and wherein the length of main drilling rod changes 1 meter into by original 4-6 rice, and both cooperate, solved and repeated to put forward the brill problem, reduce repeatedly promoting the friction of drill bit to hole wall, reduce the possibility in the hole of collapsing easily, convenient lifting is used.And changed the present situation that prior art has only main drilling rod transferring power, but the equal transferring power of every joint drilling rod of the present utility model, handling safety, labor productivity height.
Description of drawings
Fig. 1 is a drilling rod main body structure schematic diagram of the present utility model.
Fig. 2 is the cross sectional representation of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
A kind of rotatory boring castinplace pile drilling rod is divided into main drilling rod and auxilliary drilling rod, the supporting use of main and auxiliary drilling rod.Its structure is referring to accompanying drawing 1, Fig. 2, main and auxiliary drilling rod body 2 use that cooperatively interacts, be the regular hexagon structure of hollow, long about 1 meter of main drilling rod, long 3 meters or 4 meters of auxilliary drilling rod, the upper and lower screwed connection part 1 that is equipped with of main and auxiliary drilling rod body 2, two kinds of linkings of 1 fen inside and outside silk of screwed connection part.
During use, main drilling rod is installed on the slewing drilling machine, and auxilliary drilling rod is mated, and is installed on the main drilling rod.The main and auxiliary drilling rod of regular hexagon structure all uses as the drilling rod of transferring power, and main drilling rod mainly plays lifting and the auxilliary drilling rod of loading, unloading.
Claims (1)
1, a kind of rotatory boring castinplace pile drilling rod comprises main drilling rod and auxilliary drilling rod, it is characterized in that, described main and auxiliary drilling rod is the hexagonal structure of the hollow used of complementing one another, long 1 meter of wherein main drilling rod, the auxilliary long 3-4 rice of drilling rod.
