и. зубьями 11 и 12 соответственно. Устройство работает следующим образом.and. teeth 11 and 12, respectively. The device operates as follows.

в механизм 2 внедрения и извлечения устанавливается первая секция обсадных труб 3, оснащенная режущей кромкой 4 и выступами 5.the first casing section 3 is installed in the insertion and extraction mechanism 2, equipped with a cutting edge 4 and protrusions 5.

Во внутреннюю полость обсадной грубы 3 погружается рабочий орган, который при включении привода за счет реактивного момента и посредством ползунов 8, установленных в корпусе 7, взаимодействует с выступами 5 первой секции обсадной трубы 3, причем упорные зубья 11 и 12 входят в зацепление между собой. При этом реактивный буровой момент, возникающий на буровом инструменте 9 через ползуны 8 корпуса 7, передается на выступы 5 и далее обсадной трубой 3 передается на самоходное гусеничное шасси 1.A working body is immersed in the inner cavity of the casing 3, which, when the drive is switched on due to the reactive moment and by means of the sliders 8 installed in the housing 7, interacts with the protrusions 5 of the first section of the casing 3, and the abutment teeth 11 and 12 engage with each other. In this case, the reactive drilling moment arising on the drilling tool 9 through the sliders 8 of the housing 7 is transmitted to the protrusions 5 and then the casing 3 is transmitted to the self-propelled caterpillar chassis 1.

При необходимости создания дополнительного осевого усилия на буровом инструменте 9 рабочая жидкость подается в гидроцилинлры напора 10, которые передают дополнительное осевое усилие через корпус 7 всему рабочему органу и далее буровому инструменту 9, По мере выработки забоя буровой инструмент подается на забой за счет того, что ползуны 8 установлены в корпусе 7 с возможностью осеводо перемещения.If it is necessary to create additional axial force on the drilling tool 9, the working fluid is supplied to the hydraulic cylinders of the head 10, which transmit additional axial force through the housing 7 to the entire working body and then to the drilling tool 9. 8 are installed in the housing 7 with the possibility of axial movement.

После наполнения бурового инструмента 9 привод дает кратковременное 25 Обратное вращение и за счет возникшего реактивного момента выступы 5 и ползуны 8 перестают взаимодействовать (упорные зубья 11 и 12 выходят из зацепления).Рабочий орган jq поднимается на поверхность для выгрузки выбуренного грунта,при этом: гид*роцйлиндры напора 10 возвращаются в первоначальное положение и производится внедрение обсадной трубы 3 до забоя скважины.After filling the drilling tool 9, the drive gives a short-term 25 reverse rotation and due to the arising reactive moment, the protrusions 5 and the sliders 8 stop interacting (the abutment teeth 11 and 12 disengage). The working body jq rises to the surface to unload the drilled soil, while: a guide * pressure cylinders 10 are returned to their original position and casing 3 is introduced before the bottom of the well.

В дальнейшем ппоходку ведут в аналогичной последовательности.Subsequently, the haulage is carried out in a similar sequence.

Таким образом, в настоящем устройстве решена не только стабилизация рабочего органа от реактивного момента, но и созданы условия для создания дополнительного осевого усилия при проходке грунтов повышенной прочности, что в конечном итоге ведет к повышению производительности бурения по сравнению с прототипом на 20-30% и позволяет получить экономичесх<ий эффект на одну мамину в размере 8-9 тыс.руб. в год.Thus, in this device, not only the stabilization of the working body from the reactive moment was solved, but also the conditions were created for creating additional axial force when driving high strength soils, which ultimately leads to an increase in drilling productivity compared to the prototype by 20-30% and allows you to get an economic effect on one mother in the amount of 8-9 thousand rubles. in year.

Claims

The invention relates to the construction industry and can be used for drilling wells in soils of different particle size and any water cut. A device for drilling wells is known, which includes a tool, a casing, pressure cylinders and overhangs located inside the casing. However, this device has a low productivity in drilling rocks and frozen soils with boulder and pebble inclusions, as the axial force generated by this device limited only by the mass of the working body. The purpose of the invention is to increase the productivity of drilling rocky frozen soils. This is achieved by the fact that the working body is equipped with sliders having teeth and mounted on the working body with the possibility of axial movement and interacting with the projections of the casing, which are equipped with stop teeth that are installed with the possibility of interaction with the teeth of the sliders. FIG. 1 shows the proposed device; on Aig.2 - section aa of figure 1; on fig.Z - section bb of fig.

2. The device contains a self-propelled crawler chassis 1 with a casing introduction and removal mechanism 2 fixed on it, a set of casing pipes 3, the first section of which is equipped with a cutting edge 4 and protrusions 5. On the boom b of the self-propelled crawler chassis 1 a working body is hung, including body 7, sliders 8, drilling tools 9 and pressure cylinders 10. The sliders 8 are mounted in the housing 7 with the possibility of axial movement and connected to the pressure cylinders 10. The interconversion sides of the projections 5 and the sliders 8 are equipped with stop teeth 11 and 12 respectively. The device operates as follows. A first section of casing 3 is installed in the insertion and extraction mechanism 2, equipped with a cutting edge 4 and protrusions 5. A working member is immersed in the internal cavity of the casing string 3. which, when the drive is turned on by the reactive moment and by means of the sliders 8 installed in the housing 7, interacts with the protrusions 5 of the first section of the casing 3, with the stop teeth 11 and 12 meshing with each other. At the same time the reactive drilling moment arising on the drilling tool 9 through the slides 8 of the casing 7, is transferred to the protrusions 5 and further by the casing 3 is transferred to the self-propelled tracked chassis 1. If necessary, the creation of additional axial force on the drilling tool 9 working fluid is supplied to the hydrocyles head 10, which transfer additional axial force through the body 7 to the entire working body and further to the drilling tool, e. As it is developed, the drilling tool is fed to the bottom, because the slide blocks 8 are installed with the body 7 with the ability to axially; o move. After filling the drilling tool 9, the drive gives a short reverse rotation and due to the generated reactive moment, the protrusions and sliders 8 cease to interact (the stop teeth 11 and 12 go out of engagement). The tool rises to the surface to unload the drilled soil, in this case; The hydraulic cylinders of the head 10 return to their original position and are made out; the casing of the casing 3 to the bottom of the well. in the future, the walk is carried out in a similar sequence. Thus, in this device not only the stabilization of the working body from the reactive moment is solved, but also conditions are created to create additional axial force when penetrating soils with increased strength, which ultimately leads to an increase in productivity - compared to the prototype by 20-30 % and allows you to get an economic effect on one magnchina in the amount of 8-9 thousand rubles. in year. The invention The device for drilling wells, including a working body, casing, hydraulic cylinders of pressure and protrusions placed inside the casing, distinguished by the fact that, in order to increase the productivity of drilling, rocky and frozen soils, the working body is equipped with sliders having a tooth and mounted on the working body with the possibility of axial movement and interacting with the projections of the casing, which are provided with stop teeth that are installed with the possibility of interaction with the teeth of the sliders.
