Description

Недостатком известных расширителей дл  сбоечно-буровых машин  вл етс  то, что при выбуривании скважины обратным ходом необходимо снимать расширитель пр мого хода и на его место устанавливать расширитель обратного хода. Эта операци  т жела и трудоемка.A disadvantage of the known extenders for well drilling machines is that when a well is drilled in reverse, it is necessary to remove the forward expander and install a reverse expander in its place. This operation is hard and time consuming.

Предлагаемый расширитель не имеет этого недостатка, так как к нижней поверхности лучей укреплены съемные лапы с зубками.The proposed extender does not have this drawback, since removable paws with teeth are fixed to the bottom surface of the rays.

На чертеже показан предлагаемый расширитель в обшем виде. Расширитель представл ет собой корпус с трем  лучами под углом 120 друг к другу. К нижней поверхности лучей креп тс  бтъемные лапы /, в которых устанавливаютс  по четыре зубка 2 в шесть линий резани . На верхней поверхности лучей укрепл ютс  по три зубка 5. Все зубки удерживаютс  при помощи болтов 4. Лапы снимаютс  при бурении пр мым ходом.The drawing shows the proposed extender in the general form. The extender is a body with three beams at an angle of 120 to each other. To the lower surface of the rays there are fastened paws /, in which four teeth 2 are installed in six cutting lines. On the upper surface of the beams, three teeth 5 are reinforced. All teeth are retained with the help of bolts 4. The paws are removed when drilling in the forward direction.

Предлагаемый расширитель позвол ет осуществл ть бурение и расш:ирение скважин одним и тем же расширителем, исключив операцию по доставке расширител  обратного хода нан верхний штрек. Доставка лап  вл етс  простой операцией.The proposed reamer allows drilling and extension: drilling the wells with the same reamer, eliminating the operation of delivering the reamer to the upper drift. Paw delivery is a simple operation.

Предмет изобретени Subject invention

Расширитель дл  сбоечно-буровых машин, выполненный в виде стального корпуса с трем  лучами с зубками, отличаю шийс  тем, что, с целью использовани  его дл  разбуривани  скважины при обратном ходе, к нижней поверхности лучей укреплены съемные лапы с зубками .The expander for drilling and boring machines, made in the form of a steel case with three beams with teeth, differs from the fact that, in order to use it to drill a hole during the return stroke, removable feet with teeth were fixed to the bottom surface of the beams.
