(54) СОЕДИНЕНИЕ ШНЕКОВЫХ ШТАНГ(54) CONNECTION OF SCREW RODS

II

Изобретение относитс к шнековому бурению, в частности к устройствам дл соединени между собой секции шнековых штанг.The invention relates to auger drilling, in particular to devices for interconnecting a section of auger rods.

Известно соединение штанг, состо щее из стержн и наконечннка, св занных между собой штифтом. Крут щий момент передаетс через стержень, взаимодействующий с внутренними поверхност ми отверсти в штанговых наконечниках. От осевых усилий стержень удерживаетс поперечными штифтами , проход щими через сквозное отверстие в стержне и наконечниках IJ.A connection of rods is known, consisting of a rod and a tip, interconnected by a pin. The torque is transmitted through a rod that interacts with the internal surfaces of the orifices in the rod ends. From axial forces, the rod is held by transverse pins passing through the through hole in the rod and the tips IJ.

Недостатком этого устройства вл етс возможность отсоединени штифтового соеД1 нени в скважине.A disadvantage of this device is the possibility of disconnecting the pin connection in the well.

Известно соединенне шнековых штанг, содержащее Т-образный выступ, шестигранный штырь на конце одной штанги, ответный Т-образный паз н внутренний шестигранник , на конце другой штанги .2.It is known to connect screw rods containing a T-shaped protrusion, a hexagonal pin at the end of one rod, a reciprocal T-shaped groove and an internal hexagon, at the end of the other rod .2.

Недостатками этого устройства ыа, ютс поломки Т-образного выступа во врем c6q)KH и разборки секции, а также самопроизвольнбе отсоединение во врем бурени .The disadvantages of this device are the breakage of the T-shaped protrusion during c6q) KH and the disassembly of the section, as well as the spontaneous disconnection during drilling.

Цель изобретени - повышение надежности работы за счет предотвращени самопроизвольного разъединени .The purpose of the invention is to increase the reliability of operation by preventing spontaneous disconnection.

Указанна цель достигаетс тем, что соединение снабжено стержнем, размещенным во внутренней полости штанг и св занным с шестнгранным штырем, причем последний имеет возможность осевого перемещенн .This goal is achieved by the fact that the connection is provided with a rod placed in the inner cavity of the rods and connected with a hexagonal pin, the latter having the possibility of being axially displaced.

Соединенне шнековых штанг предназначено дл соединени отдельных штанг, нижн из которых имеет соединительный участок дл долота 1, а верхн заканчиваетс муфтой 2 .ОЛЯ соединени с приводом враще1$ ни . Соединение включает тело штанги 3 один конец которой имеет Т-образный выступ 4 и шестигранный штырь 5 на конце одной штанги, а близлежащий торец другой штанги имеет ответный Т-образный паз 6 н внутренний шестигранник 7. На наружнойThe connected screw rods are designed to connect individual rods, the bottom of which has a connecting area for the bit 1 and the top ends with a sleeve 2. The shaft is connected with a rotating drive. The connection includes the body of the rod 3, one end of which has a T-shaped protrusion 4 and a hexagonal pin 5 at the end of one rod, and the nearby end of the other rod has a response T-shaped groove 6 n internal hexagon 7. On the outer

Claims

A screw rod 8 is welded along the helical line along the helix, forming a century-old surface. The screw section W1 (the internal is provided with a central bolt 9 connected at the bottom to the thread with a pin 5, the latter being mounted for axial movement. The upper end of the rod extends beyond the pipe with the possibility of entering into the hole 10 of the hexagonal pin of another joined section. To the central rod 9, a washer 11 is welded, which rests in the lowermost position of the rod in pin 12. Coupling 2 (Fig. 1) also has an internal hexagon 13 with T-shaped protrusions 14 which are connected to the grooves 5 on the screw section The boom rod and the locking notch 15 for connecting to the drive shaft. At the junction of the boom rods, the T-shaped grooves and protrusions 4, 14 receive axial forces, and the hexagonal pin transmits torque in conjunction with the hexagonal notches. The auger bar joint is connected as follows First, the section of the screw rod is connected to the bit 1, for this, the end of the rod 9 protruding from the rod 3 draws the hexagon pin 5 into the interior of the pipe. After that, the T-shaped protrusion of the pipe is connected to the T-shaped groove on the hex of the bit. The joining process is completed after the rod lowers the hexagonal pin into the internal hex of the bit until the washer 11 stops on the rod with the tip 12. The following sections of screw rods are connected in the same sequence, the stem 9 protruding from the pipe 9 enters the hole 10 of the hexagon pin 4 the next section, excluding accidental movement from the area of the connection of the hexagon pin 4. The last link of this chain is in contact with the drive shaft is the coupling 2. Disassembly of the connection of the auger bar occurs in So, starting by disconnecting the shaft from the coupling. By turning the engine in the opposite direction, the drive shaft is released from the grooves 15, removes the hex pin 5 and the clutch protrusions 14 are released from the grooves b of the auger rod section. Next, for the protruding end of the rod 9, the hexagonal pin b is inserted into the interior of the pipe until it stops at the pins 12 and releases the T-shaped protrusions from the grooves of the underlying rod section. Techno-economic. The effectiveness of the proposed device consists in increasing the productivity of work and reducing the races of soda associated with the forced simply by eliminating the breakage of the joint and its spontaneous separation during the drilling process. Claims: Compound wide rods containing a T-shaped protrusion and a hexagonal pin at the end of one rod responding A typical groove and an internal pole (% - rannik at the end of the other rod, characterized in that, in order to increase the reliability by preventing spontaneous disconnection, it equipped with a rod placed in the inner cavity of the rods and connected with a hexagon socket, the latter having the possibility of axial movement.
