(54) УСТРОЙСТВО ДЛЯ ЗАТЯЖКИ КРУПНЫХ РЕЗЬБОВЫХ СОЕДИНЕНИЙ(54) DEVICE FOR TIGHTENING LARGE THREADED CONNECTIONS
1one
Изобретение относитс к механизированным устройствам дл зат жки крупных резь бовых соединений, а именно на аппаратах высокого давлени .The invention relates to mechanized devices for tightening large threaded connections, namely, high-pressure apparatus.
Известно устройство дл зат жки круп.ных резьбовых соединений, содержащее кор-., пус с поворотной головкой и храдовым механизмом , установленные в ксфпусе силовые икпкнщры, пошружиненные штоки которых взаимодействуют с прсмч ежуточным элементом, св занным с поворотной голо& кой 1 .A device for tightening coarse threaded connections is known, comprising a box, a swivel head and a stand-off mechanism, a power module installed in an xfuscous box, the spring-loaded rods of which interact with the psmch daily element associated with the swivel head & Which 1.
Недостатком этого устройства вл етс жестка св зь гфсмежуточнрго элемента с поворотной головкой, а его концы разме., щены между штоками двух силовых цилиндров , взаимодействующих с ними.The disadvantage of this device is the rigid connection of the interfacial element with a swivel head, and its ends are spaced between the rods of two power cylinders that interact with them.
Наиболее близким решением из нзвест.ных к предлагаемому вл етс устройство дл зат жки крупных резьбовых соединений; 20 содержащее корпус, установленные в нем силовые цилиндры с подпружиненными поршн ми , поворотную головку с храповым колесом и промежуточные элементы, вза..The closest solution to the proposed one is a device for tightening large threaded connections; 20 comprising a housing, power cylinders mounted therein with spring-loaded pistons, a swivel head with a ratchet wheel, and intermediate elements, an interlock ..
имодействуюшне с поворотной головкой и поршн ми t2l .and acting with swivel head and pistons t2l.
Недостаток указанного устройства заключаетс в смещении во врем работы контакта промежуточного элемента с поршн ми силовых цилин;ц)ов, что ведет к перекосу пс зшней и уменьшению ( всего устройства. Ограниченна длина промежуточного элемента оС уславливает, при необходимости получени повьш1енного крут щего момента зат жки, увеличение диаметра силовых цилиндров,The disadvantage of this device is the displacement during the operation of the contact of the intermediate element with the pistons of the power cylinders; i), which leads to a misalignment of the axle and reduction (of the whole device. The limited length of the intermediate element of the operating system makes it possible to obtain an increased tightening torque , increasing the diameter of the power cylinders,
Крсые того, пружины возврата силовых цилиндров расположены внутри их корпусов, что также влечет за собой увеличение габаритов корпусов цилиндров при установке мощных пружин или снижение крут щего момента, что обуславливает трудности при смене пружин во врем технического обслуживани устройства.Moreover, the return springs of the power cylinders are located inside their housings, which also entails an increase in the dimensions of the cylinder housings when installing powerful springs or a decrease in torque, which makes it difficult to change the springs during maintenance of the device.
