Изобретение отногатс к устройствам дл зат жки крупных резьбовых соединений.The invention relates to devices for tightening large threaded connections.
Известны устройства дл зат жки крупных резьбовых соединений, содержащие специальные гайковерты и электрические или газовые нагреватели дл тепловой зат жки, устанавливаемые во внетреннем отверстии крепежногЬ элемента 1.Devices for tightening large threaded connections are known, which contain special wrenches and electric or gas heaters for thermal tightening, which are installed in the inner hole of the fastening element 1.
Недостатком известных устройств дл зат жки вл етс их сложность и низка надежность .A disadvantage of the known tightening devices is their complexity and low reliability.
Наиболее близким к изобретению по технической сущности и достигаемому положительному эффекту, вл етс устройство дл зат жки крупных резьбовых соединений, содержащее нажимной рабочий орган в виде вкладыша с симметрично скощенными поверхност ми , воздействующими на крепежный элемент резьбового соединени , и клиновой силовой механизм, включающий один клин, взаимодействующий со скощенными поверхност ми вкладыша 2.The closest to the invention in its technical essence and the achieved positive effect is a device for tightening large threaded connections, comprising a pressure working body in the form of an insert with symmetrically curved surfaces acting on the fastening element of the threaded connection and a wedge force mechanism, including one wedge interacting with the curved surfaces of the liner 2.
Недостатком известного устройства вл етс его мала эффективность и надежность .A disadvantage of the known device is its low efficiency and reliability.
Цель изобретени - повышение надежности и эффективности устройства.The purpose of the invention is to increase the reliability and efficiency of the device.
Поставленна цель достигаетс тем, что в устройстве дл зат жки крупных резьбовых соединений, содержащем нажимной рабочий орган в виде вкладыща с симметрично скощенными поверхност ми, воздействующий на крепежный элемент резьбового соединени , и клиновой силовой механизм , взаимодействующий со скошенными поверхност ми вкладыша, силовой механизм выполнен в виде закрепл емой на крепеж .- ном элементе Т-образной головки с поперечным пазом и двух клиньев, установленных в пазу головки, симметрично оси устройства с возможностью перемещени с помощью винта и взаимодействующих с вкладышем , который размещен в пазу головки,The goal is achieved by the fact that in the device for tightening large threaded joints, containing a pressure working body in the form of an insert with symmetrically curved surfaces, acting on a fastener of a threaded connection, and a wedge force mechanism interacting with the beveled surfaces of the liner, the force mechanism is made in the form of a T-head fastened to a fastener element with a transverse groove and two wedges installed in the head groove symmetrically to the axis of the device with the possibility of moving and using a screw and interacting with the liner, which is placed in the slot of the head,
15 а устройство снабжено контактирующим с вкладыщем опорным стаканом с вырезами дл установки ключа под крепежный элемент .15 and the device is provided with a supporting cup in contact with the liner with cutouts for mounting the key under the fastening element.
На чертеже изображено устройство дл The drawing shows a device for
2Q зат жки крупных резьбовых соединений, продольный разрез.2Q tightening of large threaded connections, longitudinal section.
