PUMPING UNIT FOR OIL DRILLING, WITH A MOVEMENT CONTROL MECHANISM AND A MOBILE BODY WITHIN A ROTATING HEAD

摘要

This invention refers to a pumping unit for drilling oil in the field of oil prospecting equipment, comprising an oil well stem (120) which alters the length of said stem (120). The halter adjustment mechanism applied to a pumping unit for oil drilling comprises a fixed body (10) fitted with a peripheral support for fixing the steel cables (11) attached to the head (110) of the pumping unit (100). On the periphery of the fixed body (10) guides (12) are placed, wherein the peripheral support is displaced, a position sensor (121) being provided on the top end of such guide (12). The movement control mechanism of a mobile body within a rigid head of a pumping unit, which is the object of this invention, comprises equipment composed of a fixed portion (31) and a mobile portion (36). The fixed portion (31) comprises a reducer set (32), with a differential gear box (33) and the engine thereof (10) and a control system (38). The mobile portion (36) comprises a rotating head (35) over which a mobile body is attached (39), with a worm gear (37), a master gear (34), transfer gears (11), (12) and (13) and a movement system (14).
