Изобретение относитс к строительной технике, в частности к устройствам дл бестраншейного образовани горизонтальных скважин.The invention relates to construction equipment, in particular, to devices for trenchless formation of horizontal wells.
На чертеже изображено устройство, обп(ий вид.The drawing shows the device, obp (nd view.
Устройство состоит из направл ю- щей pai«a 1, на которой смонтированы привод подачи в виде гидравлических домкратов 2 и нажимна плита 3. К ккыка плита 3 содержит фикси- РУЮШ1Я& торцовые кулачки 4, в которых зафиксирован т opei. нажимной штйнтн 5. Передний торец нажимной 5 Находитс в сопр жении с Хвостовой частью пр мого расширител 6. Во внутренней полости.нажимной плиты 3 смонтирован зажим в виде внутренних 7 и внешних 8 клиньев , через которые пропущено гибкое т нущее звено 9. Конец гибкого т нущего звена 9 зафиксирован в встречном расширителе 10 посредством шайбы 1. Гибкое т нущее звено 9 содержит неподвижно закреплённые упоры 12, меющие .форму усеченных конусов. На внутренних клинь х 7 выполнена кони- еска упорна фаска 13.The device consists of a guide pai “a 1 on which the feed drive in the form of hydraulic jacks 2 and the pressure plate 3 are mounted. To plate 3, the plate contains fixed gears & end cams 4, in which fixed opei. push rod 5. Front end push 5 Is in conjunction with the Tail portion of the straight extender 6. In the inner cavity of the clamp plate 3, a clip is mounted in the form of inner 7 and outer 8 wedges, through which the flexible pull link 9. The end of the flexible t the lower link 9 is fixed in the opposing expander 10 by means of the washer 1. The flexible and the lower link 9 contains fixed supports 12, which form the form of truncated cones. The inner wedge x 7 is made of a conical thrust chamfer 13.
Устройство дл расширени пионерой скважины работает следующим бразен.The pioneer well expansion device operates as follows.
В предварительно образованной ионерной.скважине располагаетс ибкое т нущее звено 9 которое оедин етс со встречным расшириелем 10 посредством шайбы П. ругой конец т нущего звена 9 ропускаетс через внутреннюю олость пр мого расширител 6 и ажимной плиты 3. При этом гибкое нущее звено 9 находитс в сопр ении с зажимными клинь ми 7.In the preformed ioner well, there is a flexible pull link 9 which connects with the counter expander 10 by means of a washer. The other end of the pull link 9 is rotated through the internal cavity of the right expander 6 and the aging plate 3. At the same time, the flexible lower link 9 is in clamping wedges 7.

Кроме того, пр мой расширитель 6 соедин етс с нажимной плитой 3 при помощи штанги 5 и фиксирую щих торцовых кулачков 4,При подаче рабочей жидкости в гидравлические домкраты 2 нажимна плита 3 перемещаетс по раме 1 в торону скважины. При этом нажимное усилие от гидравлических домкратов 2 передаетс через нажимную плиту 3 и штангу 5 на пр мой расширитель 6, В результате пр мой расширитель 6 перемещаетс и расшир ет пионерную скважину. При этом гибкое т нущее звено 9 свободно скользит по зажимным клинь м 7, т.е. встречный расширитель 10 остаетс на месте.In addition, the straight expander 6 is connected to the pressure plate 3 by means of a rod 5 and locking end cams 4. When the working fluid is supplied to the hydraulic jacks 2, the pressure plate 3 moves along the frame 1 into the well of the well. The pressure force from the hydraulic jacks 2 is transmitted through the pressure plate 3 and the rod 5 to the direct expander 6. As a result, the direct expander 6 moves and expands the pioneer well. In this case, the flexible section of the lower link 9 slides freely along the clamping wedge of the m 7, i.e. counter dilator 10 remains in place.
После завершени пр мого хода гидравлические домкраты 2 переклюг- чаютс на обратный ход, в результате чего нажимна плита 3 возвращаетс в исходное положение. При гтом зажимные клинь 7 взаимодействуют с упорами 12, неподвижно закрепленными на гибком т нущем звене 9. Упорное звено 12 проходит через разжатые клинь 7 и своим большим диаметром взаимодействует с их торцами. After the completion of the forward stroke, the hydraulic jacks 2 are switched over to the reverse stroke, as a result of which the pressure plate 3 returns to its original position. With the DGT, the clamping wedges 7 interact with the lugs 12 fixedly mounted on the flexible connecting link 9. The thrust link 12 passes through the decompressed wedges 7 and with its large diameter interacts with their ends.
В результате этогб взаимодействи осуществл етс передача т нущего усили от гидравлических домкратов 2 на встречный расширитель 9 посредством упоров 12 и т нущего звена 9, т.е. осуществл етс процесс расширени скважины встречным расширителем 10 при обратном ходе устройства .As a result of this interaction, the transfer of the pull force from the hydraulic jacks 2 to the counter expander 9 is carried out by means of the stops 12 and the pull link 9, i.e. The well expansion process is performed by the counter expander 10 during the return stroke of the device.
После наращивани штанги 5 рабочий цикл устройства повтор етс .After increasing the rod 5, the operation cycle of the device is repeated.
