Description

Дл  разрушени  крепких пород при проходке шахтных-стволов бурением примен ют фрезерные буры, приводимые во врашение гидравлическим или электрическим способом.For the destruction of hard rock when drilling shaft-shafts by drilling, milling drills are used that are driven by hydraulic or electrical means.

С целью повышени  эффективности разрушени  пород подобными бурами предлагаетс , согласно изобретению , располагать между отдельными их фрезами вибраторы.In order to increase the efficiency of rock destruction by such drills, it is proposed, according to the invention, to position vibrators between their separate cutters.

На фиг. 1 и 2 изображены две проекции предлагаемого бура.FIG. 1 and 2 two projections of the proposed drill are shown.

Фрезерный бур выполнен в виде корпуса }, насаженного на центральную буровую трубу 2. На шести лучах - кронштейне 3 корпуса смонтированы фрезы 4 и вибраторы 5, расположенные поочередно по окружности бура. Фрезы и вибраторы привод тс  в действие от индивидуального электрического или гидравлического привода через редукторы 6. В качестве привода могут быть использованы глубоководный электродвигатель или гидравлическа  многоступенчата  турбина , котора  соедин етс  с буровой трубой патрубками 7.The milling drill is made in the form of a body}, mounted on the central drill pipe 2. On six beams - bracket 3 of the case, mills 4 and vibrators 5 are mounted, alternately arranged around the circumference of the drill. The cutters and vibrators are driven by an individual electric or hydraulic drive through gears 6. A deep-water electric motor or a hydraulic multistage turbine that is connected to the drill pipe by nozzles 7 can be used as a drive.

Применение вибраторов повышает эффективность работы бура, так как они сообшают частицам породы забо  вынужденные колебани , способствуюшие уменьшению сил их взаимного сцеплени  и разрушают благодар  этому структуру породы забо .The use of vibrators increases the efficiency of the drill, as they impart early vibrations to the rock particles, which contribute to the reduction of their mutual adhesion forces and thereby destroy the structure of the bottom rock.

Предмет изобретени Subject invention

Фрезерный бур, отличающийс  тем, что, с целью разрушени  структуры породы забо , между фрезами расположены вибраторы.A milling drill, characterized in that, in order to destroy the structure of the bottom rock, vibrators are located between the mills.
