Abstract
The utility model discloses a kind of drilling rig, comprise support platform, support platform is supported with drilling rod, the upper end of drilling rod is provided with percussion mechanism, support platform is provided with rotation motor, and the output shaft of rotation motor is connected with the upper transmission of drilling rod, and the lower end of drilling rod is provided with drill bit, the bottom of drill bit is back taper, and the side of back taper is provided with fin.The maximum rotating diameter of fin is greater than the external diameter of drilling rod.Percussion mechanism is hydraulic hammer, and rotation motor is hydraulic motor.The mode that Xia Za limit, limit can be adopted to rotate, greatly reduces the hammer force of needs, and rock stratum can be squeezed broken and clamp-on the borehole wall by fin, neither need very large hammer force, will not discharge by sandy soil again, and the drilling rod in later stage promotes conveniently, easy construction, is applicable to the rock stratum of various characteristic.
Description
Technical field
The utility model relates to a kind of rig, particularly relates to a kind of drilling rig.
Background technology
Drilling rig of the prior art mainly contains rotary and gravity, and rotary is crept into by bit, while blown out by the sandy soil under brill by wind or water; Gravity is while pound by under weight, is taken out of by sandy soil by the one way valve of the hollow of weight inside and bottom.These two kinds of device shortcomings all need to discharge sandy soil, and construction is complicated.
Also have in prior art and pound by under weight, sandy soil are clamp-oned the method for the borehole wall.But this method of the prior art needs very large weight power, and the hammer stem in later stage promotes difficulty, and larger by the restriction of formation characteristics.
Summary of the invention
The purpose of this utility model is to provide a kind of easy construction, is applicable to the drilling rig of various sand boulder bed.
The purpose of this utility model is achieved through the following technical solutions:
Drilling rig of the present utility model, comprise support platform, described support platform is supported with drilling rod, the upper end of described drilling rod is provided with percussion mechanism, described support platform is provided with rotation motor, and the output shaft of described rotation motor is connected with the upper transmission of described drilling rod, and the lower end of described drilling rod is provided with drill bit, the bottom of described drill bit is back taper, and the side of described back taper is provided with fin.
The technical scheme provided as can be seen from above-mentioned the utility model, the drilling rig that the utility model embodiment provides, comprise support platform, upper end due to drilling rod is provided with percussion mechanism and rotation motor, the side of the back taper of drill bit bottom is provided with fin, the mode that Xia Za limit, limit rotates can be adopted, on the one hand, because the contact area of fin and rock stratum is less, greatly reduce the hammer force of needs, on the other hand, in the process that Xia Za limit, limit rotates, rock stratum can be squeezed broken and clamp-on the borehole wall by fin, neither need very large hammer force, will not discharge by sandy soil again, and the drilling rod in later stage promotes conveniently, easy construction, be applicable to various sand boulder bed.
Accompanying drawing explanation
The structural representation of the drilling rig that Fig. 1 provides for the utility model embodiment.
In figure:
1, hydraulic hammer, 2, rotation motor, 3, support platform, 4, connecting joint, 5, drilling rod, 6, drill bit, 7, fin.
Detailed description of the invention
To be described in further detail the utility model embodiment below.
Drilling rig of the present utility model, preferably detailed description of the invention is as shown in Figure 1 for it:
Comprise support platform, described support platform is supported with drilling rod, the upper end of described drilling rod is provided with percussion mechanism, described support platform is provided with rotation motor, the output shaft of described rotation motor is connected with the upper transmission of described drilling rod, the lower end of described drilling rod is provided with drill bit, and the bottom of described drill bit is back taper, and the side of described back taper is provided with fin.
Described support platform is provided with connecting joint, and the upper end of described drilling rod is connected with described connecting joint, and the output shaft of described rotation motor and described connecting joint are connected by gear or chain or belt.
The side of described back taper is circumferentially evenly provided with 2 to 4 fins, and described fin rises or spiral along the sided linear of described back taper.
The maximum rotating diameter of described fin is greater than the external diameter of described drilling rod.
Described percussion mechanism is hydraulic hammer, and described rotation motor is hydraulic motor.
The drilling rig of the utility model embodiment, upper end due to drilling rod is provided with percussion mechanism and rotation motor, the side of the back taper of drill bit lower end is provided with fin, the mode that Xia Za limit, limit rotates can be adopted, on the one hand, because the contact area of fin and rock stratum is less, greatly reduce the hammer force of needs, on the other hand, in the process that Xia Za limit, limit rotates, rock stratum can be squeezed broken and clamp-on the borehole wall by fin, neither need very large hammer force, will not discharge by sandy soil again, and the drilling rod in later stage promotes conveniently, easy construction, is applicable to various sand boulder bed.
The drilling rig of the utility model embodiment is not the finger water intaking well of narrow sense, but the various boring of the finger of broad sense, as architecture foundation pile boring etc.
The above; be only the utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
