Oilfield automatic feed descaling and dewaxing device with movable lifting mechanism

Abstract

The invention relates to the technical field of an oilfield automatic feed descaling and dewaxing device, in particular to an oilfield automatic feed descaling and dewaxing device with a movable lifting mechanism. The oilfield automatic feed descaling and dewaxing device comprises a blade assembly, a rubber scraper assembly and a movable lifting mechanism, wherein the movable lifting mechanism comprises two groups of symmetrically arranged movable assemblies; each group of movable assemblies comprises a first motor, a lead screw, a second motor and a pressing device; the lead screw is longitudinally connected with the first motor; the pressing device is transversely connected with the second motor and is connected with one end of the lead screw through a nut seat; and the other end of the lead screw is provided with a bearing seat. According to the oilfield automatic feed descaling and dewaxing device, the lead screw is driven by the first motor to do spiral movement so as to drive the pressing device connected with the lead screw to do up-down vertical movement, so that the automatic feed descaling and dewaxing device can be used for timely, effectively and comprehensively removing a large amount of accumulated wax, oil and scales attached to the outer surfaces of a pumping rod, an oil pipe and a drill stem and is convenient to operate and use, and the descaling and dewaxing effect is favorably improved.

Description

technical field [0001] The invention relates to the technical field of oil field automatic feed descaling and wax removal devices, in particular to an oil field automatic feed descaling and wax removal device with a moving lifting mechanism. Background technique [0002] The oil field automatic feeding descaling and wax removal device is a new type of environmental protection device used to remove oil or wax deposits and scale deposits on sucker rods, oil pipes and drill pipes. Because during the downhole operation, when the sucker rod, oil pipe or drill pipe is pulled out, a large amount of wax, oil and scale will be attached to the outer surface, so it needs to be removed in time. However, because the length of the sucker rod, oil pipe or drill pipe is relatively long, it is very inconvenient to operate during the descaling and wax removal operation, and it is impossible to effectively remove a large amount of wax deposits on the outer surface of the sucker rod, oil pipe o...
