Description
лёнии с помощью ..блокирующего устрой :тве . ;. . Дл привода дели 6 приводной вал мотора 7 соединен с валом ведущей вездо оси 10. На валу ведущей звездочки 10 укреплены два приводных цепных {{олеса 11, KOTojaie наход тс в зацеплении с цепью б и привод т ее в зависмости от вращени верхнего вала мотр ра 7. Между цепными колесами 11 укреп , лен стопор 12f с помощью которого стопор тс цепи 6 по окончании операцив завинчивани труб или в начале их развинчивани . Стопор 12 выполнен в виде колеса 13 с зубь ми 14, котоfoe можно ввести в зацепление с зубь ми 15 на зубчатой рейке 16, котора может двигатьс из положени Выключено в положение, когда ее зубь соедин ютс с зубь ми 14 колеса 13. Привод стопора 12 осуществл етс гидроцилиндром 17.Leni with .. blocking device: tve. ;. . For drive 6, the drive shaft of the motor 7 is connected to the drive axle 10 shaft. On the drive sprocket shaft 10, two drive chains {{11a, KOTojaie are fixed to the chain b and lead to it depending on the rotation of the upper shaft 7. Between the sprockets 11 strengthened, flap 12f with the help of which the stopper of the vehicle 6 of the chain 6 at the end of the operation of screwing in the pipes or at the beginning of their unscrewing. The stopper 12 is made in the form of a wheel 13 with teeth 14, which can be engaged in engagement with the teeth 15 on a toothed rack 16, which can move from the switched off position to when its teeth are connected to the teeth 14 of the wheel 13. Drive the stopper 12 carried out by the hydraulic cylinder 17.
Конструкци цилиндра 8 дл разъема трубного соединени аналогична конструкции цилиндра 9 дл соединени На концах штоков цилиндров 8 и 9 поворотно укреплены ведомые звездочки 18 и 19.The design of the cylinder 8 for the pipe joint connector is similar to that of the cylinder 9 for connection. At the ends of the cylinder rods 8 and 9, driven sprockets 18 and 19 are rotatably fixed.
Устройство работает следУкщим образом.The device works as follows.
Гидромотор 7 может приводить цепной привод в другую сторону,если рейка 16 установлена в положение Выключено, чтобы захватывающее устройство 3 вращать в том или иномThe motor 7 can drive the chain drive in the other direction if the rail 16 is set to Off to allow the gripper 3 to rotate in one direction or another.
направлении, когда трубы свинчиваютс или развинчиваютс . Гидромотор 7 заклинивает цепь 6, когда он блокирован рейкой 16 зубь ми 14 и 15„direction when the pipes are screwed or unscrewed. The hydraulic motor 7 sticks the chain 6 when it is blocked by the rail 16 teeth 14 and 15 "
При вьщвижении штоков гидроцилиндров 8 и 9 со звездочками 18 и 19 создаетс увеличенна сила т ги на заклиненную цепь 6 и, перемеща захваты с плашками 4 по направл ющим дугам, создаетс крут щий момент, достаточный осуществлени полного свинчивани или дл страгировани резьбы труб в начале развинчивани .When the hydraulic cylinders 8 and 9 rotate with sprockets 18 and 19, an increased thrust force is generated on the jammed chain 6 and, by moving the grips with the dies 4 along the guide arcs, a torque is generated that is sufficient to fully tighten or to thread the pipes at the beginning of unscrewing. .
