Abstract
1. Устройство для снятия буровой коронки со штанги, включающее корпус с продольным пазом под штангу и приводом, и установленный в совмещенных каналах, выполненных на боковых стенках корпуса, стержень с фиксатором для штанги, отличающееся тем, что привод выполнен в виде гидродомкрата и не менее двух гидроцилиндров, гидравлически связанные с гидродомкратом, при этом ось гидродомкрата, взаимодействующая с фиксатором штанги, расположена перпендикулярно к продольной оси штанги, а штоки гидроцилиндров установлены с возможностью взаимодействия с торцом буровой коронки и расположены параллельно продольной оси штанги.2. Устройство для снятия буровой коронки со штанги по п.1, отличающееся тем, что оно снабжено упорным элементом, расположенным между торцом коронки и корпусом, и установленным с возможностью осевого перемещения вдоль буровой штанги.3. Устройство для снятия буровой коронки со штанги по п.2, отличающееся тем, что фиксатор для буровой штанги выполнен из двух элементов, внутренняя поверхность которых конгруэнтна наружной поверхности штанги, при этом один из элементов установлен с возможностью взаимодействия со штоком гидродомкрата, а второй размещен между буровой штангой и фиксатором.1. A device for removing the drill bit from the rod, including a housing with a longitudinal groove under the rod and the drive, and installed in the combined channels made on the side walls of the housing, a rod with a latch for the rod, characterized in that the drive is made in the form of a hydraulic jack and not less two hydraulic cylinders, hydraulically connected to the hydraulic jack, the axis of the hydraulic jack interacting with the rod clamp is perpendicular to the longitudinal axis of the rod, and the hydraulic cylinder rods are installed with the possibility of interaction I with the end face of the drill bit and are parallel to the longitudinal axis of the rod. 2. The device for removing the drill bit from the rod according to claim 1, characterized in that it is equipped with a thrust element located between the end face of the crown and the housing, and installed with the possibility of axial movement along the drill rod. 3. The device for removing the drill bit from the rod according to claim 2, characterized in that the retainer for the drill rod is made of two elements, the inner surface of which is congruent with the outer surface of the rod, while one of the elements is installed with the possibility of interaction with the hydraulic jack rod, and the second is located between drill rod and retainer.
