Description
Известен механический ключ дл свинчивани и развинчивани бурильных труб. Недостатком известного устройства вл етс то, что дл привода его требуетс установка электродвигателей значительной мощности или сложных редукторов с большим иередаточным отношением , так как величина момента, потребного дл раскреплени резьбового соединени бурильных труб, достигает больших значений, в то же врем дл закреплени резьбового соединени величина потребного момента незначительна.A mechanical key for screwing and unscrewing drill pipes is known. A disadvantage of the known device is that to drive it, it is necessary to install electric motors of considerable power or complex gearboxes with a large gear ratio, since the magnitude of the torque required to release the threaded joint of the drill pipe reaches high values, while at the same time to secure the threaded joint required moment is negligible.
Такое выполнение ут л ел ет ключ и делает его малопригодным дл использовани в буровых установках облегченного тииа. С пелью ликвидации указанных недостатков предлагаетс ключ, отличаюш,ийс от известного тем, что в механизме его привода применена электромагнитна муфта, одна половина которой выполпена в виде маховика, способного аккумулировать энергию в периоды холостого вращени электродвигател и отдавать ее дополнительно в периоды пиковых нагрузок механизма.Such an embodiment fills the key and makes it unsuitable for use in lightweight rigs. With the elimination of these drawbacks, a key is offered, which differs from the well-known fact that an electromagnetic clutch is used in its drive mechanism, one half of which is made in the form of a flywheel capable of storing energy during idle rotation of the electric motor and giving it in addition during peak loads of the mechanism.
На чертеже изображена схема ключа с приводом от индивидуального электродвигател .The drawing shows a diagram of a key driven by an individual electric motor.
Электродвигатель 1 (фиг. 1) моитируетс на корпусе 2 ключа; к валу электродвигател прикрепл етс половина 3 электромагнитной муфты, котора размещаетс между электродвигателем и мехаиизмом ключа. Друга половина муфты насажена на вал редуктора ключа.. В варианте ключа, с отбором мощности от основных механизмов буровой установки электромагнитна муфта монтируетс между механизмом ключа и валом отбора мощности.The electric motor 1 (Fig. 1) is motivated on the key body 2; Half of an electromagnetic clutch is attached to the motor shaft, which is located between the motor and the key mechanism. The other half of the coupling is mounted on the key reducer shaft. In the variant of the key, with power take-off from the main mechanisms of the drilling rig, an electromagnetic clutch is mounted between the key mechanism and the power take-off shaft.
Предмет изобретени Subject invention
Механический ключ дл свинчивани и развинчивани бурильных труб, отличающийс тем, что, с целью сокращени потребл емой мощности, в ириводе ключа нрименена электронагиитна муфта, одиа половииа которой вынолнена в виде маховика.A mechanical key for screwing and unscrewing drill pipes, characterized in that, in order to reduce power consumption, an electro-hygienic clutch is inserted in the key irivide, and some of them are designed as a flywheel.
