Abstract

The invention relates to the technical field of petroleum workover operation devices and methods, in particular to an automatic elevator for a sucker rod in oilfield workover operation and a use method. According to the technical scheme, the upper part of a large bevel gear is engaged with a bevel pinion, the lower part of the large bevel gear drives clamping jaws, and a stepping motor drives themultiple clamping jaws to advance and retreat through transmission of the bevel pinion and the large bevel gear; an inductive sensor is installed on the lower surface of an elevator box; and the stepping motor, a stepping motor driver and a stepping motor controller are connected with an elevator end cover through bolts, a direct-current power supply is installed on the upper surface of the elevator end cover, the elevator box is installed on a hanging ring through a hanging hook, and the elevator end cover is connected with the elevator box through bolts. The automatic elevator has the advantages that clamping of a push bearing surface shoulder of the sucker rod is completed through the clamping jaws, and the automation of the elevator is achieved through the inductive sensor; and the workover operation efficiency is improved, the labor intensity of workers is reduced, the personal safety of the workers is guaranteed, and the transformation from man-machine collaborative operation toautomation and intelligentization is achieved.

Description

technical field [0001] The invention relates to the technical field of a device and method for oil workover operations, in particular to an automatic sucker rod elevator for oil field workover operations and a method for using it. Background technique [0002] At present, in the process of oilfield workover operations in our country, the wellhead operation is still dominated by workers' manual operation, which is a heavy and dangerous labor. Therefore, there have been many automation equipment for wellhead operations in China. Elevators are an important part of automatic workover equipment, and the realization of elevator automation is one of the main signs of mechanization and automation of wellhead operations. The elevator is an important device for lifting and lowering tubing and sucker rods in drilling and workover operations, and its performance directly affects the efficiency and safety of drilling and workover operations. In traditional drilling and workover operatio...
