When the catwalk conveys a single sleeve to the drilling platform surface, the swing arm hydraulic cylinder extends out to drive the H-shaped swing arm to swing by a certain angle and carry the hydraulic elevator to the joint of the sleeve, and then the hydraulic elevator is opened under the action of hydraulic power and clamps the single joint of the sleeve.

When the hydraulic elevator clamps the single joint of the casing pipe, the driller controls the top drive to move upwards along the track, and the single casing pipe gradually stands up and moves to the position of the central line of the wellhead of the derrick under the action of the H-shaped swing arm and the hydraulic elevator. When the bottom of a single casing is higher than the height of the wellhead casing pile, the driller stops lifting the top drive and controls the top drive to be lowered, and the lower joint of the casing is located on the upper joint of the wellhead casing pile.

The top drive is continuously lowered, the hydraulic power head is lowered along with the top drive until a grouting sealing device of the sleeve clamping device is inserted into a certain position in the sleeve, the top drive is stopped from being lowered, pressure oil is injected into the power head through an oil port to enable the cylinder body to move downwards, the push-pull sleeve also moves downwards due to the fact that the push-pull sleeve and the cylinder body are fixedly connected, the clamping sleeve is clamped in a groove of the push-pull sleeve and a groove of the lifting cylinder through a first boss and a second boss respectively, when the push-pull sleeve moves downwards, the lifting cylinder also moves downwards under the connection effect of the clamping sleeve, the sleeve is tightly held through slips in the sleeve clamping device, and when the cylinder body moves downwards, the swing arm seat slides along the anti-torque frame under the guiding effect of the sliding support and the sliding block.
