Technical field
The present invention relates to engineering machinery fields, more specifically, in particular to a kind of power head and rotary drilling rig.
Background technique
Rotary drilling rig is a kind of engineering machinery that can be drilled in soil layers such as sand, cohesive soil, slity soils.Specific implementation
When, the good casing of pre-plugged, the drill bit of the rotary drilling rig back spin that gently lands turns on brill, is promoted and is portalled when filling soil sand material in drill bit
Outside, the soil sand material in drill bit is poured over cubic metre of earth vehicle or predetermined region by rotary drilling rig cycle, and then drill bit valve is shut, rotary digging
Drilling machine screws to former drilling position and continues to tunnel, and does not stop in proper order, can easily drilling machine to prescribed depth.Meanwhile rotary digging
For the maximum drilling diameter of drilling machine up to 1.5~4m, maximum depth of pore forming is 60~90m, can satisfy all kinds of large foundation constructions
Requirement, therefore, rotary drilling rig be widely used in urban construction, highway bridge, industrial civil building, diaphram wall, water conservancy,
The fields such as antiseepage slope protection.
Power is provided for the driving to drilling machine drilling rod, power head is generally connected on the drilling rod of rotary drilling rig, at present
For, generally there are two types of the power heads of form and drilling rod to cooperate for rotary drilling rig: mill resistance bar and machine locking bar.So-called frictional resistance bar, i.e., only
It pressurizes merely with the weight of drilling rod itself to ground, can only generally beat less hard stratum, such as soil layer, layer of sand, to dynamic
Power is of less demanding, it is only necessary to provide torque to drilling rod.So-called machine locking bar has pressurization wrinkle spline on drilling rod, power head can
To pressurize by pressurization spline to drilling rod, harder stratum, such as rock layers can be drawn an analogy, but the ratio generally beaten is shallower, and shadoof
When need to unlock, efficiency is very low.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of power head, which is designed by its structure, can not only
It is being crept into softly with hard place, and drilling depth can be greatly improved.
A kind of power head, including power head ontology are provided with boring for external of being connected up and down in the power head ontology
The interspersed guide hole of bar, the power head ontology top are provided with gripping sleeve, clamping and institute of the gripping sleeve for outer drill rod
Stating gripping sleeve can rotate synchronously with outer drill rod, and pressurization oil cylinder is provided with below the power head ontology, and the pressurization oil cylinder is used
Pressurization when outer drill rod drilling.
Preferably, it is arranged in below the power head ontology there are two the pressurization oil cylinder settings and in vertically symmetrical
Two sides.
Preferably, the clamping cylinder radially arranged there are two being arranged on the gripping sleeve.
The present invention also provides a kind of rotary drilling rig, it is provided with drilling rod on the rotary drilling rig, is arranged with outside the drilling rod
Power head described in above-mentioned any one.
The beneficial effects of the present invention are: the power head provided by the invention is when drilling rod carries out rotary drilling, gripping sleeve can
It is rotated synchronously with firm grip drilling rod and with drilling rod, while the oil cylinder that pressurizes can pressurize in rod boring, so as to
The drilling power of drilling rod is greatly improved, it is ensured that drilling rod can not only crept into hard place softly, and it is deep that drilling can be greatly improved
Degree.
Detailed description of the invention
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this

The attached drawing of offer obtains other attached drawings.
Fig. 1 is the overall structure diagram of power head disclosed in the embodiment of the present invention.
Specific embodiment
In order to make those skilled in the art better understand the technical solutions in the application, below in conjunction with the application reality
The attached drawing in example is applied, the technical scheme in the embodiment of the application is clearly and completely described, it is clear that described implementation
Example is merely a part but not all of the embodiments of the present application.
Based on the embodiment in the application, those of ordinary skill in the art are obtained without making creative work
The all other embodiment obtained, shall fall within the protection scope of the present application.
In the description of the present invention, it is to be understood that, the instructions such as term " top ", " lower section ", " axial direction ", " radial direction "
Orientation or positional relationship is to be based on the orientation or positional relationship shown in the drawings, and is merely for convenience of the description present invention and simplification is retouched
It states, rather than the device or element of indication or suggestion meaning must have a particular orientation, be constructed and operated in a specific orientation,
Therefore it is not considered as limiting the invention.
A kind of specific embodiment of power head of the present invention is provided referring to Fig. 1, Fig. 1, wherein Fig. 1 is the embodiment of the present invention
The overall structure diagram of disclosed power head.
As shown in Figure 1, present embodiments providing a kind of power head, which includes power head ontology 1, the power head
