Mechanized Workover Operation Lifting Ring Centralizing Device

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 well workover operation in the petroleum industry, in particular to a method and device for straightening a lifting ring in mechanized well workover operation. Background technique [0002] When removing and hanging rings in ordinary workover operations, it needs to be done manually. The labor intensity of the workers is high, and there are certain safety hazards. Therefore, a device for removing and hanging rings in mechanized workover operations has been developed. However, the device has the following problems during use. Under the influence of wind or other factors, the suspension rings suspended by the operation hook will deviate, which will affect the efficiency and success rate of removing and hanging the suspension rings. Contents of the invention [0003] The object of the present invention is to provide a lifting ring straightening device for mechanized well workover operation, so ...
