FIELD: reinforcement bars production.
SUBSTANCE: invention relates to universal devices for fixation, twisting and swirling of parts of wellhead equipment. Device contains a key with a handle connected to the working head with two levers located perpendicular to the handle and parallel to each other so that an open mouth is formed. Total length of key is 250–650 mm, length of each lever is 50–70 mm, diameter of each lever is 10–30 mm, distance between levers is 32–60 mm. Levers are fixed on working head with possibility of fixation of wellhead accessories between them and are detachable for replacement with another type and size. Working head comprises a ratchet mechanism configured to switch the side of rotation on which a pipe wrench comprising a tubular lock is mounted.
EFFECT: improved operational characteristics, increased efficiency and efficiency of operations at the well, reduced time and labor costs for repair, as well as installation and dismantling works at the wellhead, reduced probability of injuries.
