Claims (5)

1. Устройство для присоединения в бурильной колонне, в частности, в витом трубопроводе, для генерации в ней вибрации или ударов при закачивании текучей среды, например, бурового раствора, через бурильную колонну, отличающееся тем, что оно выполнено в виде гидравлического цилиндра (1) двойного действия, имеющего автоматически смещаемые переключающиеся клапаны (18, 20) и содержащего корпус (4) цилиндра, поршень (6), разделяющий корпус цилиндра на две отдельных камеры (15, 17) и двойной трубчатый шток (8) поршня, сквозь который текучая среда во время работы устройства будет протекать через переключающиеся клапаны (18, 20) и камеры (15, 17) цилиндра, при этом цилиндр (1), по меньшей мере, с одного конца, выполнен с резьбовой частью (14, 16) для присоединения к бурильной колонне.1. Device for connecting in a drill string, in particular in a twisted pipe, for generating vibration or shock in it when pumping a fluid, for example, a drilling fluid, through a drill string, characterized in that it is made in the form of a hydraulic cylinder (1) double action, with automatically shifting switching valves (18, 20) and containing a cylinder body (4), a piston (6) that separates the cylinder body into two separate chambers (15, 17) and a double tubular piston rod (8) through which the fluid working environment the device will flow through the switching valves (18, 20) and chambers (15, 17) of the cylinder, while the cylinder (1), at least from one end, is made with a threaded part (14, 16) for connection to the drill string . 2. Устройство по п. 1, отличающееся тем, что переключающиеся клапаны (18, 20) являются двумя качающимися клапанами, расположенными в поршне (6) с каждой стороны наклонной перегородки (34), которая делит внутренность штока поршня на два отдельных пространства, каждое из которых соединено с соответствующим качающимся клапаном (18, 20) для ограничения входного прохода (36) и выходного прохода (38), соответственно, для протекания текучей среды через качающиеся клапаны в камеры (15, 17) цилиндра и из них. 2. The device according to claim 1, characterized in that the switching valves (18, 20) are two swing valves located in the piston (6) on each side of the inclined partition (34), which divides the inside of the piston rod into two separate spaces, each of which it is connected to the corresponding swing valve (18, 20) to restrict the inlet passage (36) and the exit passage (38), respectively, for the flow of fluid through the swing valves to and from the cylinder chambers (15, 17). 3. Устройство по п. 2, отличающееся тем, что качающиеся клапаны (18, 20) приспособлены для механического смещения. 3. The device according to claim 2, characterized in that the swinging valves (18, 20) are adapted for mechanical displacement. 4. Устройство по п. 3, отличающееся тем, что каждый из качающихся клапанов (18, 20) выполнен в виде клапанного элемента, скользяще поддерживаемого в осевом направлении с помощью валов (19, 21) в двух клапанных отверстиях (22, 26 и 24, 28, соответственно), выполненных в концевых стенках (23, 25) поршня, и открывающихся в соответствующую камеру (15,17) цилиндра, причем качающиеся клапаны выполнены с возможностью смещения при столкновении с концевыми стенками (10, 11) цилиндра. 4. The device according to p. 3, characterized in that each of the swinging valves (18, 20) is made in the form of a valve element that is slidably supported in the axial direction by means of shafts (19, 21) in two valve openings (22, 26 and 24 , 28, respectively) made in the end walls of the piston (23, 25) and opening into the corresponding chamber (15.17) of the cylinder, the swinging valves being made with the possibility of displacement in a collision with the end walls (10, 11) of the cylinder. 5. Устройство по любому из предшествующих пунктов, отличающееся тем, что ход поршня (6) находится в диапазоне 10 - 50 мм, и частота перемещения поршня находится в диапазоне 2 - 5 циклов в сек. 5. The device according to any one of the preceding paragraphs, characterized in that the piston stroke (6) is in the range of 10 to 50 mm, and the frequency of movement of the piston is in the range of 2 to 5 cycles per second.
