Description
(54) УСТРОЙСТВО ДЛЯ ЗАТЯЖКИ КРУПНЫХ РЕЗЬБОВЫХ СОЕДИНЕНИЙ(54) DEVICE FOR TIGHTENING LARGE THREADED CONNECTIONS
1one
Изобретение относитс к созданию и эксплуатации машин и аппаратов, в частности сосудов, работающих под давлением, и может быть использовано в химической, энер гетической и других отрасл х промышленности .The invention relates to the creation and operation of machines and apparatus, in particular, pressure vessels, and can be used in the chemical, energy and other industries.
Известно устройство дл зат жки резьбовых соединени методом осевой выт жки, состо щее из гидроцилиндра, поршн и упор ного стакана 1.A device for tightening threaded joints by the method of axial drawing consisting of a hydraulic cylinder, a piston and a thrust cup 1 is known.
Недостаток указанного устройства заключаетс в невозможности создани больших усилий зат жки, в св зи с большими габаритами гидродомкрата и необходимости использовани при этом гибких шлангов и насосов высокого давлени .The disadvantage of this device is the impossibility of creating large tightening forces, due to the large dimensions of the hydraulic cylinder and the need to use flexible hoses and high-pressure pumps.
Наиболее близким к предлагаемому вл етс устройство дл зат жки крупных резьбовых соединений, содержащее силовой привод , упорный элемент, выполненный в виде стакана, взаимодействующую с ним опорную гайку, наворачиваемую на хвостовик резьбового соединени т гу, свободный конец которой соединен с опорной гайкой 2.Closest to the present invention is a device for tightening large threaded joints, containing an actuator, a thrust element made in the form of a cup, a supporting nut cooperating with it and rolling on the shank of a threaded connection, the free end of which is connected to the supporting nut 2.
Недостатком известного устройства вл етс то, что дл использовани этого устройства необходимо крепление упорного элемента . Кроме того, устройство создает малые усили зат жки.A disadvantage of the known device is that to use this device it is necessary to mount the stop element. In addition, the device creates small tightening forces.
Цель изобретени -увеличение усили предварительного раст жени элемента резьбового соединени . The purpose of the invention is to increase the prestressing force of the threaded element.
Поставленна цель достигаетс тем, что устройство дл зат жки крупных резьбовых соединений, содержащее силовой привод, упорный элемент, взаимодействующую с ним опорную гайку, наворачиваемую на хвостовик резьбового соединени , т гу, свободный конец которой соединен с опорной гайкой, снабжено надетой на опорную гайку рабочей головкой с рычагом, фиксатором, упорный элемент выполнен в виде резьбовой втулки и взаимодействующего с ней стакана, имеющего на боковой поверхности отверстие дл размещени фиксатора, св зывающего стакан с гайкой резьбового соединени , а втулка выполнена с рычагом, шарнирно св занным с корпусом силового привода, шток которого соединен с помощью щарнира с рычагом рабочей головки.The goal is achieved by the fact that the device for tightening large threaded joints, containing an actuator, a thrust element, a supporting nut cooperating with it, wound on the threaded end of the threaded connection, the thru, the free end of which is connected to the supporting nut, is fitted with a working nut. a head with a lever, a retainer, the stop element is made in the form of a threaded sleeve and a cup interacting with it, which has an opening on its side surface to accommodate a retainer connecting the cup with the nut the threaded connection, and the sleeve is made with a lever pivotally connected to the body of the power drive, the stem of which is connected with the help of a hinge to the lever of the working head.
