Reciprocating type petroleum pumping unit lifting rope replacing device

Abstract

The invention relates to the field of petroleum pumping, in particular to a reciprocating type petroleum pumping unit lifting rope replacing device. The reciprocating type petroleum pumping unit lifting rope replacing device comprises a mounting bottom plate, a first supporting frame, a limiting assembly, a clamping assembly and the like, the first supporting frame is connected to the top of the mounting bottom plate, the limiting assembly is arranged on the first supporting frame, and the clamping assembly is arranged on the mounting bottom plate. Through cooperation of a Y-shaped limiting frame, a pushing frame and the devices on the pushing frame, when the Y-shaped limiting frame does not extrude the pushing frame any more, the pushing frame and the devices on the pushing frame can reset under the reset effect of a third spring, clamping frames can reset under the guiding effect of a grooving plate, the clamping frames loosen a new lifting rope clamped on the clamping frame, then the new lifting rope can be bent under the gravity effect of the new lifting rope and separated from the two clamping frames located on a lower position, the new lifting rope can fall onto the first limiting frame, and therefore the old lifting rope is replaced with the new lifting rope, danger caused by the fact that manual replacement is carried out on the new lifting rope is avoided, and the effect that replacement can be automatically carried out on the lifting rope is achieved.

Description

technical field [0001] The invention relates to the field of oil pumping, in particular to a reciprocating oil pumping unit suspension rope replacement device. Background technique [0002] Petroleum is a viscous, dark brown liquid, which is mainly processed into fuel and gasoline. At the same time, petroleum is also a raw material for many chemical industrial products, such as solutions, fertilizers, pesticides and plastics. With the increase in demand, the oil extraction technology has become more mature. The oil extraction first needs to be well drilled at a specific location. The oil in the well is extracted. [0003] There is generally a donkey head on the oil pumping unit, and the sling for hanging the sucker rod column goes around the donkey head. One end of the sling is fixed at the wellhead, and the other end is connected to the polished rod. After the pumping unit has been used for a period of time, it needs to be wound To replace the sling on the donkey’s head, ...

Problems solved by technology

[0004] Based on this, it is necessary to address the above problems and propose a reciprocating oil pump that can automatically clamp the new suspension rope for subsequent operations, and can automatically replace the old suspension rope with a new suspension rope to avoid the danger of artificial replacement. Machine sling replacement device to solve the problems of safety hazards and low work efficiency in the artificial replacement of slings proposed in the background technology
