Title: Elevator for tubing and boring pipes
Inventor: KUDIN V G
IPC: E21B19/06
Filed: 2001-08-22
Granted: 2004-03-10
Abstract: FIELD: well boring and maintenance equipment. SUBSTANCE: elevator has body with boss and platform. Body is pivotally connected to hanger by means of fingers. Jaws with a coupling rod are pivotally interconnected and placed inside the body. Locking means is made in form of rotatable handle with spring-loaded lever, placed inside the boss. Upper end of lever is connected to spring-loaded fixing part, which can interact with the platform. Lower end of lever can interact with groove in the boss. Torsion spring is placed in the groove made in the bushing of handle. At one end torsion spring is fixed in the boss with a screw, at other end it is fixed inside the bushing of handle for displacing the handle to a closed position of elevator. Two concentric grooves are made on outer surface of said bushing, into which elastic slide rings are inserted made for example from polyurethane. In each external ear of hanger in the area of hanger and finger conjunction two single- axis apertures are made. In one of said apertures wedge with threaded part is placed. In the middle of the wedge a groove is formed, groove having a bevel edge in contact with groove in the finger. Bushing is screwed onto threaded part of the wedge. Bushing is placed in another single-axial aperture and jammed by means of pin to prevent its longitudinal displacement in the hanger. Wedge is moved into position for jamming the finger by clockwise rotation of bushing by means of face wrench. Wedge is moved into position for dismantling the finger by counter-clockwise rotation of bushing up to the stop. EFFECT: increased safety and durability. 3 cl, 6 dwg

Abstract: Изобретение относится к области трубопроводной арматуры, к способу сборки шарового крана, подсоединенного к трубопроводной системе для текучих сред, в частности к способу изготовления корпуса, предназначенного для размещения в нем шара, посредством сварки. Способ изготовления шарового крана, содержащего корпус крана и шар, включает следующие стадии. Подготавливают две половины корпуса для образования корпуса крана и шар, имеющий сквозной канал. Противоположные открытые концы шара выполнены плоскими. При этом две половины корпуса выполнены таким образом, чтобы они представляли собой зеркально-симметричные тела, формы которых определяются разделением корпуса крана в середине между двумя отверстиями. Предварительно снабжают шар двумя углублениями. В две половины корпуса соответственно устанавливают кольцевые седла крана. Каждое из седел образует уплотнение между наружной поверхностью шара и внутренней поверхностью корпуса крана. Состыковывают две половины корпуса их открытыми концами, которые соответственно противоположны отверстиям, так чтобы охватывать шар. С другой стороны удерживают шар в таком положении, чтобы он был повернут на угол 90° от нормального рабочего положения шарового крана. Центральная линия сквозного канала в этом случае находится на одной прямой с рабочей осью шара и перпендикулярно пересекает прямую линию, проходящую через центры двух отверстий и центр шара. Сваривают состыкованные открытые концы двух половин корпуса для образования корпуса крана. Затем, не изменяя положение шара, посредством механической обработки выполняют отверстия для установки соответственно двух штоковых узлов в тех местах корпуса крана, которые соответственно обращены к обоим плоским открытым концам сквозного канала шара, так чтобы центры отверстий находились на рабочей центральной линии шарового крана. Затем поворачивают шар на угол 90° в нормальное рабочее положение шарового крана, так чтобы сквозной канал располагался на уровне обоих отверстий корпуса крана. При этом углубления шара располагаются на уровне обоих отверстий корпуса. Затем соответственно закрепляют два штоковых узла в обоих отверстиях и соответственно вставляют штоки в оба углубления. После чего соответственно приваривают два штоковых узла по окружности к краям отверстий. Изобретение направлено на уменьшение количества составных частей при изготовлении поворотного шарового крана, на экономию расходов на его изготовление, а также на устранение вредных воздействий термической деформации корпуса вследствие сварки, что позволяет изготовить шаровой кран с высокой точностью. 7 з.п.ф-лы, 5 ил.
