Abstract
The utility model relates to a double concentric drill gyrator, and belongs to the field of drilling equipment. The double concentric drill gyrator comprises a large drill rod, a small drill rod, and a large drill rod drive shaft, wherein the small drill rod is arranged inside the large drill rod. The small drill rod is driven to rotate by a motor arranged on the small drill rod. A wheel gear is fixedly arranged on the large drill rod drive shaft, and is meshed with a wheel gear fixedly arranged on the large drill rod. The large drill rod is driven to rotate by a motor arranged on the large drill rod drive shaft. The double concentric drill gyrator is capable of effectively increasing rock drilling speed, and substantially reducing production cost.
Description
Technical field
The utility model relates to drilling equipment, particularly can effectively improve and bore rock speed, the two coaxial rig gyrator of decrease cost of production.
Background technology
Down-the-hole drill is widely used in geological prospecting, the mine production.Not only revolving force but also impact force all are passed to drill bit from rig to existing down-the-hole drill in use.After the hole depth of boring reached certain depth, the steel pipe that diameter is identical with the aperture inserted in the hole of boring, and then proceeded boring.Its weak point is that brill rock speed is slow, and cost of production is high.
Summary of the invention
The purpose of this utility model provides and a kind ofly can effectively improve the rock speed of boring, and decrease cost of production two drive coaxial large and small drill rod mechanism.
Technical solution of the present utility model is that two coaxial rig gyrators comprise large drilling rod, be located at the macaroni in the large drilling rod, macaroni is by its rotation of motor-driven that is located on the macaroni, also comprise large drilling rod driving shaft, be installed with gear on this driving shaft, this gear and the gear engagement that is installed on the large drilling rod, large drilling rod is by its rotation of motor-driven that is located on the large drilling rod driving shaft.
The bottom of above-described large drilling rod can be provided with drill bit.
The motor that is located on the large drilling rod driving shaft described in the utility model can be oil motor.
The motor that is located on the macaroni described in the utility model is oil motor.
Operating principle of the present utility model is that the steel pipe in the hole that existing insertion is bored changes large drilling rod into, in the bottom of large drilling rod drill bit is installed, and utilizes oil motor by the large drilling rod rotation of large drilling rod drive shaft, thereby realizes that large drilling rod and macaroni hole simultaneously.
The utility model has the advantages that effectively to improve and bore rock speed, decrease cost of production.
Description of drawings
Fig. 1 is organigram of the present utility model.
The specific embodiment
As shown in Figure 1, two coaxial rig gyrators comprise large drilling rod 1, are installed in the macaroni 2 in the large drilling rod 1, and macaroni 2 drives its rotation by the motor 6 that is installed on the macaroni 1.The utility model also is provided with large drilling rod driving shaft 3, is installed with gear 4 on the large drilling rod driving shaft 3, gear 4 and gear 5 engagements that are fixedly mounted on the large drilling rod 1, and large drilling rod 1 drives its rotation by the motor 7 that is installed on the large drilling rod driving shaft 3.
Drill bit can be installed in the bottom of large drilling rod 1 of the present utility model.
The motor 6 that is installed on the large drilling rod driving shaft 3 of the present utility model is oil motors.
The motor 7 that is installed on the macaroni 2 of the present utility model is oil motors.
Large drilling rod 1 connects with support by taper roll bearing 8.Macaroni 2 connects by the endoporus of taper roll bearing 9 with large drilling rod 1.Large drilling rod driving shaft 3 connects with support by taper roll bearing 10.
