The working principle of the invention is as follows:

when the reverse pressurization is not used, namely when the second piston rod 2012 at the pressurization end is not required to act, the oil circuit of the second annular cavity 2014 is a passage by controlling the valve element, the valve element can be a hydraulic control one-way valve, the first piston rod 2011 at the lifting end moves upwards, the second annular cavity 2014 absorbs oil, oil is fed from the second oil port, the first piston rod 2011 moves downwards, oil is discharged from the second annular cavity 2014, and oil is discharged from the third oil port; when the oil enters the first oil port two and the first oil port four, the first piston rod 2011 is driven to move upwards, and at the moment, the oil exits from the first oil port one and the first oil port three; when the first oil port i and the first oil port three feed oil, the first piston rod 2011 is driven to move downwards, and at the moment, the first oil port two and the first oil port four discharge oil;

when reverse pressurization is needed, the second piston rod 2012 of the pressurization end is controlled to extend downwards through the valve element, so that the first lifting steel wire rope 202 and the pressurization steel wire rope 206 are ensured to be lifted, after the second piston rod 2012 of the pressurization end extends out, the second oil port and the third oil port are sealed and blocked through the control valve element to lock the oil circuit of the second annular sub-cavity 2014, at the moment, the first piston rod 2011 of the lifting end and the second piston rod 2012 of the pressurization end cannot move relatively, the first piston rod 2011 of the lifting end and the second piston rod 2012 of the pressurization end form a piston rod, and the second piston rod 2012 of the pressurization end is driven to perform the same action by controlling the first piston rod 2011 of the lifting end to move upwards or downwards;

when lifting an oil pipe, the first piston rod 2011 of the lifting end is controlled to move upwards, the first piston rod 2011 pushes the lifting crown block 207 to move upwards, the lifting crown block 207 drives the hook 205 to move upwards through the first lifting steel wire rope 202, because the first piston rod 2011 of the lifting end and the second piston rod 2012 of the pressurizing end cannot move relatively, the first piston rod 2011 also drives the second piston rod 2012 of the pressurizing end and the reverse pressurizing crown block 203 to move upwards, and the lifting crown block 207 and the reverse pressurizing crown block 203 synchronously move during lifting.

When an oil pipe is fed, the first piston rod 2011 is controlled to move downwards, the first piston rod 2011 of the lifting end and the second piston rod 2012 of the pressurizing end form a piston rod at the moment, the first piston rod 2011 can push the second piston rod 2012 of the pressurizing end to move downwards, the second piston rod 2012 pushes the reverse pressurizing crown block 203 to move downwards, the pressurizing steel wire rope 206 drives the hook 205 to move downwards, the reverse pressurizing crown block 203 and the lifting crown block 207 move downwards synchronously, and then the synchronous operation of the lifting end and the pressurizing end of the main oil cylinder 201 can be realized.
