Description

Предлагаемое изобретение касаетс  особого устройства соединени  между штангами и долотом дл  ударного бурени , имеющего назначением предупреждение обрыва долота во врем  работы, что обыкновенно вызывает большой простой и  вл етс  одной из самых трудных работ при бурении. Дл  достижени  означенной цели на долото надеваетс  хомут, св занный с ним двум  т гами.The present invention relates to a special joint device between the rods and the drill bit, with the purpose of preventing the bit from being broken during operation, which usually causes a large downtime and is one of the most difficult tasks in drilling. To achieve this goal, a yoke is attached to the bit associated with it by two tons.

Соединение штанги с долотом при ударном бурен и показано на схемати-, ческом чертеже в общем виде.The connection of the rod with the bit during shock is boring and is shown on the schematic drawing in general form.

В цел х предотвращени  отвинчивани  долота А в месте соединени  его конической нарезкой Е с долб щей штангой Д, на последнюю надевают хомут Б, состо щий из двух половин, скрепленных винтами. На хомуте Б делаютс  два отверсти  С, С, к которым креп тс  две загнутые т ги Ж, Ж круглого железа, приЁаренные своими основани ми к верхнейIn order to prevent the unscrewing of the bit A at the junction of its conical thread E with the socket bar D, a collar B consisting of two halves fastened with screws is put on the latter. On the collar B, two openings C, C are made, to which two bent holes F, F of round iron, attached to the upper

кромке долота А. Сверху т ги Ж, Ж имеют припа нные планки с отверсти ми, через которые проход т винты, скрепл ющие т ги Ж, Ж с концами хомутов Б. В случае обрыва долота А, т ги Ж, удержат долото в подвешенном положении , а при долблении твердых пород будут преп тствовать отвинчиванию долота А от штанги Д, устран   тем самым причину падени  долота на дно, вследствие нарущени  конического соединени  долота со штангой.to the edge of the chisel A. From above the mounts G, M have soldered strips with holes through which the screws fasten the glands M, M with the ends of the hose clamps. B. In the event of a bit breaking A, m, M, will keep the bit suspended the position, and when hammering hard rocks, will prevent the unscrewing of the bit A from the rod D, thereby eliminating the cause of the drop of the bit to the bottom, due to the violation of the conical connection of the bit with the rod.

Предмет изобретени .The subject matter of the invention.

Долото дл  ударного бурени , отличающеес  тем, что к верхней долота А приварены две т ги Ж, Ж, скрепленные с концами хомута Б, ст нутого на штанге Д, с целью предотвращени  отвинчивани  долота во врем  работы.Chisel for percussion drilling, characterized in that two treads G, G attached to the ends of the collar B, mounted on rod D, are welded to the upper bit A in order to prevent the bit from unscrewing during operation.
