Abstract
Изобретение относитс к технике дл геофизических исследований скважин. Цель изобретени - повышение надежности в работе . Внутри корпуса 1 размещен электромеханический привод 3. Силовой шток 4 соединен посредством т ги 5 со штоком 6. Шток 6 выполнен заодно с зубчатой рейкой, котора сцепл етс с зубчатым колесом (К) 7. Зубчата рейка штока 8 входит в зацепление с К 7. Шток 8 шарнирно соединен с рычагом 9 непосредственно. Второй конец рычага 9 св зан с выносным зондом 10. Конец штока 6 св зан с рычагом 9 при помощи подпружиненного стержн И. При работе щток 4 движетс вверх, увлекает за собой рейку штока 6. Рейка штока 6 вращает К 7, которое перемещает рейку штока 8 вниз. Рычаг 9 поворачиваетс и перемещает зонд 10 до контакта со стенкой скважины. За счет входа зубчатых реек в сцепление с К 7 силы от гидростатического давлени передаютс на корпус 1 и уравновешиваютс . Снижаетс мощность электропривода, сокращаютс осевые габариты прибора, рабочий ход штока 4 сокращаетс в два раза. 3 ил. i СЛThe invention relates to a technique for well logging. The purpose of the invention is to increase reliability in operation. Inside the housing 1 an electromechanical actuator 3 is placed. The power rod 4 is connected by means of cable 5 to the rod 6. The rod 6 is made integral with the toothed rack, which engages with the toothed wheel (K) 7. The toothed rod of the rod 8 engages K 7. The rod 8 is pivotally connected to the lever 9 directly. The second end of the lever 9 is connected to the external probe 10. The end of the rod 6 is connected to the lever 9 by means of a spring-loaded rod I. When the shaft 4 is working, it moves upwards, pulling the rod 6 along itself. The rod 6 rotates K 7, which moves the rod rail 8 down. The lever 9 rotates and moves the probe 10 until it contacts the wall of the well. By entering the gear racks into coupling with K 7, the forces from the hydrostatic pressure are transmitted to the housing 1 and are balanced. The power of the electric drive is reduced, the axial dimensions of the device are reduced, the stroke of the rod 4 is halved. 3 il. i SL
