Claims (2)

1. Устройство для развальцовки труб в скважине, включающее корпус с центральным каналом, резьбами для соединения со скважинным оборудованием и углублениями на наружной поверхности, в которых размещены ролики, установленные на осях, верхние концы которых закреплены в корпусе разъемно, а нижние - установлены в опорах, размещенных в корпусе с помощью шарниров с возможностью поворота их в плоскости, проходящей через продольные геометрические оси корпуса и роликов, отличающееся тем, что верхние концы осей роликов установлены в корпусе с радиальным зазором, а в центральном канале корпуса размещен гидравлический кольцевой поршень, подпружиненный в осевом направлении и имеющий толкатели, взаимодействующие с верхними концами осей роликов.1. A device for expanding pipes in a well, including a housing with a central channel, threads for connecting to downhole equipment and recesses on the outer surface, in which rollers are mounted on axles, the upper ends of which are fixed in the housing detachably, and the lower ones are mounted in supports placed in the housing using hinges with the possibility of rotation in a plane passing through the longitudinal geometric axis of the housing and rollers, characterized in that the upper ends of the axes of the rollers are installed in the housing with nym clearance and in the central channel housing a hydraulic annular piston is situated, the spring-loaded in the axial direction and having pushers cooperating with upper ends of the roller axes. 2. Устройство п.1, отличающееся тем, что величина зазора между корпусом и верхними концами осей роликов приблизительно равна разности между диаметром скважины и внутренним диаметром трубы после ее развальцовки.2. The device of claim 1, characterized in that the gap between the body and the upper ends of the axes of the rollers is approximately equal to the difference between the diameter of the well and the inner diameter of the pipe after its expansion.
