Technical Field

[0001] The invention relates to the field of sucker rod operation automation, and in particular to a sucker rod elevator positioning and guiding device. Background Art

[0002] Traditional sucker rod lifting and lowering operations mainly rely on manual operations, which are labor-intensive, inefficient, and have high safety risks. For example, the lifting and lowering of the sucker rod during well repair operations requires workers to repeatedly lift the elevator and remove the lifting ring, which is not only time-consuming and labor-intensive, but also prone to accidents due to improper operation.
