Abstract
1. Устройство для центрирования скважинных приборов, содержащее систему (основная система) выпуклых пластинчатых рессор, подвижно связанных своими концами с крайними опорными ползунами, скользящими по опорной направляющей, отличающееся тем, что оно снабжено дополнительной системой выпуклых пластинчатых рессор, на концевых участках каждой из которых установлены с возможностью скольжения по направляющей соответствующей рессоры основной системы.2. Устройство для центрирования скважинных приборов по п.1, отличающееся тем, что на концевых участках каждой рессоры основной системы выполнены пазы, по которым перемещаются шарниры на концах соответствующей рессоры дополнительной системы, число рессор которой равно количеству рессор основной системы.1. A device for centering downhole tools, containing a system (main system) of convex plate springs movably connected at their ends with extreme support sliders sliding along a support guide, characterized in that it is provided with an additional system of convex plate springs, at the end sections of each of which installed with the possibility of sliding along the guide of the corresponding spring of the main system. 2. The device for centering downhole tools according to claim 1, characterized in that at the end sections of each spring of the main system, grooves are made along which hinges move at the ends of the corresponding spring of the additional system, the number of springs of which is equal to the number of springs of the main system.
