Abstract

The invention discloses a lifting ring righting method and a device in a mechanical well repairing operation, wherein the device comprises a support base, a lifting device, a rotary driving device, front-back righting arms and left-right righting arms, wherein one ends of the front-back righting arms are connected with the rotary driving device for enabling the front-back righting arms to rotate; and the left-right righting arms are fixed in the middles of the front-back righting arms. The rotary driving device is mounted on the lifting device at the lower side; and the lifting device drives the rotary driving device and the front-back righting arms and the left-right righting arms to perform the vertical lifting action. A driving gear is arranged at the output shaft end of the rotary driving device; and two front-back righting arms are provided, and each front-back righting arm is engaged with the driving gear through a driven gear arranged on one end. Double-piston rod hydraulic cylinders are mounted on the front-back righting arms; and the two ends of each hydraulic cylinder is connected with two left-right righting arms through extension rods to drive the left-right righting arms to horizontally extend. The device realizes automatic righting of lifting rings, so that the labor intensity of workers is relieved, and the potential safety hazard is reduced; and the device is simple in structure, low in investment and convenient to operate.

Description

Technical field [0001] The invention relates to an auxiliary device for mechanized workover operations in the petroleum industry, in particular to a method and device for centralizing rings of mechanized workover operations. Background technique [0002] Common workover lifting rings need to be done manually. Workers are labor intensive and there are certain safety hazards. Therefore, a mechanized workover lifting ring device has been developed, but this device has the following problems during use. Under the influence of wind or other factors, the hoisting ring suspended by the work hook will shift, which will affect the efficiency and success rate of lifting the hoisting ring. Summary of the invention [0003] The purpose of the present invention is to provide a mechanized workover operation lifting ring centralizing device, which improves the centering accuracy of the elevator and the lifting ring when the lifting ring is connected to the elevator. [0004] In order to achieve t...
