Description

Существующие механизмы раскрыти  вставного долота сложны по конструкции и ненадежны в работе.The existing mechanisms for opening the insert bit are complex in design and unreliable in operation.

Описываема  конструкци  свободна от этого недостатка. Особенность предлагаемого гидравлического привода заключаетс  в том, что в нем применено золотниковое устройство дл  перекрыти  потока промывочной жидкости, помещенного между корпусом и расположенным в нем цилиндром, а также обратного клапана, преп тствующего поступлению жидкости из затрубного пространства в полость труб. Дл  перевода долота из рабочего положени  в транспортное захватное устройство снабжено порщнем- Уплотн юща  часть обратного клапана выполнена в виде кольцевой резиновой «юбки, ограниченной в крайних положени х металлическими детал ми.The design described is free from this disadvantage. A feature of the proposed hydraulic drive is that it uses a spool valve to shut off the flow of flushing fluid placed between the body and the cylinder located in it, as well as a check valve that prevents the flow of fluid from the annulus into the tube cavity. To transfer the chisel from the working position to the transporting gripping device, it is equipped with a piston. The sealing part of the check valve is made in the form of an annular rubber skirt, bounded in extreme positions with metal parts.

На фиг. 1 показан гидравлический привод механизма раскрыти  вставного долота при рабочем положении последнего; на фиг. 2 показан этот же привод механизма при переводе долота в транспортное положение .FIG. Figure 1 shows the hydraulic drive of the mechanism for opening the insert bit at the working position of the latter; in fig. 2 shows the same drive mechanism when translating the bit into the transport position.

Согласно изобретению, привод механизма имеет порщень / со щтоком 2, цилиндр 3, корпус 4, корпус золотника 5, обратный клапан б. поршень 7 и верхний цилиндр 8.According to the invention, the drive of the mechanism has a piston / with a brush 2, a cylinder 3, a housing 4, a valve spool 5, a check valve b. piston 7 and upper cylinder 8.

Перевод вставного долота из транспортного положени  в рабочее производитс  путем нагнетани  в трубы промывочной жидкости, котора , двига сь по трубам, входит в верхнюю часть вставного долота и. продолжа  путь, отмеченный на фиг. 1 стрелками,, давит на порщень / снизу, что приводит его со щтоком 2 в верхнее положение, а так как щток соединен с лапами долота, то долото принимает рабочее положение .The transfer of the insert bit from the transport position to the working position is carried out by pumping a flushing fluid into the pipes, which, moving through the pipes, enters the upper part of the insert bit and. continuing the path marked in fig. 1 arrows, presses on the bottom / bottom, which brings it with the rod 2 to the upper position, and since the shaft is connected to the paws of the bit, the bit assumes the working position.

Выточка Г (см. фиг. 1) на штоке при крайнем верхнем положении поршн  1 располагаетс  против выступа золотника 5, и тем самым открывает путь промывочной жидкости к промывочным отверсти м долота через обратный клапан 6, который отжат струей к корпусу 4.The undercut G (see Fig. 1) on the rod at the extreme upper position of the piston 1 is located opposite the protrusion of the spool 5, and thus opens the way for the flushing fluid to the flushing holes of the bit through the check valve 6, which is jetted to the housing 4.

№ 112631- 2 -No. 112631-2 -

В транспортном и рабочем положени х долота, проход в золотнике 5 перекрыт телом штока (фиг. 2), что позвол ет на поверхности фиксировать переход долота в рабочее положение по давлению на насосах, а также осуществл ть перевод долота в рабочее положение в начальный период движени  жидкости, т. е. при малых р,асходах. Последнее имеет значение в турбинном бурении, так как в начальный период турбобур еще не вращаетс .In the transport and operating positions of the bit, the passage in the spool 5 is blocked by the stem body (Fig. 2), which allows the bit to be transferred to the working position by pressure on the pumps and the bit to move to the working position in the initial period of movement. liquids, i.e., at small p, ashods. The latter is important in turbine drilling, since the turbo-drill is still not rotating in the initial period.

Выточка Г имеет малый размер в осевом направлении, поэтому при небольщих отклонени х долота от рабочего положени , проход в золотнике сужаетс , давление на порщень возрастает и создаетс  дополнительное усилие, автоматически восстанавливающее рабочее положение долота.The undercut G has a small size in the axial direction, therefore, with small deviations of the bit from the working position, the passage in the spool narrows, the pressure on the piston increases and an additional force is created that automatically restores the working position of the bit.

Перевод долота в транспортное положение производитс  путем спуска на канате порщн  7 в верхний цилиндр 8 и последующего подъема порщн , во врем  которого под порщнем / образуетс  разр жение, а над ним -давление столба жидкости в затрубном пространстве. Этот перепад давлени  вызывает опускание поршн  и, следовательно, долота.The bit is moved to the transport position by lowering the cable 7 into the upper cylinder 8 and the subsequent lifting of the matrix, during which under the formation / discharge, and above it the pressure of the liquid column in the annulus. This pressure drop causes the piston and, therefore, the bit to lower.

Перевод долота в транспортное положение может быть осуществлен также без спуска в долото поршн  7 путем повыщени  давлени  в затрубном пространстве. Такой способ удален в тех случа х, когда подъем долота производитс  без помощи каната - путем закачки жидкости в затрубное пространствоПредмет изобретени The transfer of the bit into the transport position can also be carried out without lowering the piston 7 into the bit by increasing the pressure in the annulus. This method is removed in cases where the bit is lifted without the help of a rope — by pumping fluid into the annulus.
