Изобретение относитс к инструменту дл ударно-вращательного бурени .The invention relates to a tool for percussion rotary drilling.
ИзвестНЫ колонковые шарошечные долота дл ударно-вращательнОГО бурени , вклвдчаюшие шарошки, съемную апору, состо шую из корпуса и цилиндрических цапф, а такж-е пи лот-долото.Known core cone bits for percussion-rotary drilling, including roller cone, a removable support consisting of a body and cylindrical spigots, as well as a pi lot-chisel.
С целью увеличени диаметра керна и повышени надежности опоры, предложено долото , у которого корПус опоры выполнен в виде втулки пр моугольного сечени со сквозным каналом, соосным и совпадаюшим по размерам с каналом в колонковом пилотедолоте .In order to increase the diameter of the core and increase the reliability of the support, a chisel has been proposed, in which the support cube is made in the form of a rectangular bushing with a through channel coaxial and coincident in size with the channel in the pilot pilot hammer.
На чертеже показано долото, обший вид.The drawing shows a chisel, a general view.
Долото состоит из пилота-долота /, шарошек 2, гаек 3, корпуса опоры 4, цилиндрических цапф-5, корпуса 6 долота, кернор:Вател 7 и переходника cS. П.илот-долото 1 съемное и выполнено дл колонкового бурени .A chisel consists of a pilot-chisel /, a roller cutter 2, nuts 3, a support body 4, cylindrical trunnions-5, a housing 6 bits, a core: Watel 7 and an adapter cS. P. pilot chisel 1 is removable and made for core drilling.
Шарошкн 2 закреплены гайками 3 на цилиндрических цапфах 5. В корпусе 6 установлен л ернорватель 7. Корпус 6 через переходник 8 св зан с колонковой трубой. Корпус опоры 4 выполнен в виде втулки пр моугольного сечени со СКВОЗНЫМ каналом .9, соосным и совпадающим по размерам с каналом 10 в колонковом пилоте-долоте /.The roller 2 is fixed by nuts 3 on cylindrical pins 5. In the case 6, a latch device 7 is installed. The case 6 is connected through an adapter 8 to the core tube. The casing of the support 4 is made in the form of a rectangular bushing with a CUTTING channel .9 coaxially and coincident in size with channel 10 in the pilot column-bit.
Предмет изобретени Subject invention
Колонковое шарошечное долото дл ударно-врашательного бурени , включающее шарошки , съемную опору, состо щую из корпуса н цилиндрических цапф, а также пилотдолото , отличающеес тем, что, с целью увеличени диаметра керна и повышени надежности опоры, корпус опоры выполнен в виде втулки пр моугольного сечени со сквозным каналом, соосным и совпадающим по размера-м с каналом в колонковом пилоте-долоте.A pellet drill bit for percussion drilling including a roller cutter, a removable support consisting of a body and cylindrical trunnions, as well as a pilot-hammer, characterized in that, in order to increase the core diameter and increase the reliability of the support, the support body is made in the form of a rectangular sleeve sections with a through channel coaxially and coinciding in size with the channel in the pilot-chisel column.
