When the hoisting ring swinging device works, the elevator 13 lifts the pipe string 14 into the well, and after the pipe string 14 is clamped, the elevator 13 can be lifted only under the condition that the elevator 13 is completely separated from the pipe string 14, and the hole of the elevator 13 is completely separated from the coupling of the pipe string 14.

The single lifting ring is a whole formed by three parts of components, namely a lower lifting lug 1, a hanging rod 2 and an upper lifting lug 10, and two lifting rings are shared during operation.

The hydraulic mechanism comprises a hydraulic cylinder 5, a hydraulic oil pipeline a21, a hydraulic oil pipeline b22, a hydraulic oil pipeline c23, a hydraulic oil pipeline d24, a hydraulic control integrated block 16 and an electromagnetic directional valve 17, wherein the hydraulic cylinder 5 mainly comprises a piston rod 4, a fork 12, a cylinder barrel and a rodless cavity end 11, the cylinder barrel is divided into a rodless cavity 19 and a rod cavity 20, the electromagnetic directional valve 17 is provided with two electromagnets for switching directions, namely 1DT and 2 DT; the piston rod 4 is arranged at one end of the hydraulic cylinder 5, the hydraulic cylinder 5 is connected with the hydraulic control integrated block 16 through a hydraulic oil pipeline a21 and a hydraulic oil pipeline b22, and the hydraulic control integrated block 16 is connected with the electromagnetic directional valve 17 through a hydraulic oil pipeline c23 and a hydraulic oil pipeline d 24; the hydraulic control manifold block 16 comprises a hydraulic control check valve 18, an oil port A25 and an oil port B26, wherein the hydraulic control check valve 18 is connected with the oil port A25 and the oil port B26; the electromagnetic directional valve 17 selects the 1DT electromagnet to be electrified and sucked, and the oil inlet is arranged at the oil port B26; the 2DT electromagnet is selected to be electrified for attraction, and the oil inlet A25 is formed.
