Description
Известны талевые блоки подъемно-опускных устройств буровых установок, выполненные с захватным приспособлением, вмонтированным в корпус блока. Однако эти талевые блоки не обеспечивают дистанционное управление захватным приспособлением.Known talevy blocks lifting and lowering devices of drilling rigs, made with a gripping device, mounted in the block body. However, these pulley blocks do not provide remote control gripping device.
Описываемое устройство устран ет этот недостаток за счет того, что в нем применены гидродомкраты, штоки которых шарнирно соединены с рабочими органами захватного приспособлени , у которого рабочие поверхности, так же как и у буровой колонны, выполнены со взаимно захватывающимис скосами, что разгружает захватное приспособление от распорных усилий.The described device eliminates this disadvantage due to the fact that it uses hydraulic jacks, the rods of which are hingedly connected to the working bodies of the gripping device, in which the working surfaces, like the drill string, are made with mutually gripping bevels, which unloads the gripping device from spacers effort.
На чертеже схематически в разрезе изображен талевый блок подъемно-опускного устройства в закрытом (а) и открытом (б) положении.The drawing schematically shows a section of the traveling block of the lifting and lowering device in the closed (a) and open (b) position.
В сварном корпусе / блока на ос х 2 шарнирно подвешены захватные приспособлени 5 и 4, которые шарнирно соединены со штоками поворотных гидродомкратов 5 и б. Гидродомкраты монтируютс на подшипниках кронштейнов 7, прикрепленных к корпусу, на котором также установлен гидронасос 8 с защитным кожухом 9. Рабочие поверхности захватов выполнены в виде скосов 10. Аналогичные ответные скосы выполнены на буртике буровой колонны П.In the welded body / block on the axis x 2, the gripping devices 5 and 4 are pivotally suspended, which are pivotally connected to the rods of the swivel jacks 5 and b. Hydrojacks are mounted on bearings of brackets 7 attached to the housing, on which the hydraulic pump 8 is also mounted with a protective casing 9. The working surfaces of the grippers are made in the form of bevels 10. Similar response bevels are made on the collar of the drill string P.
