The outer side of the piston sleeve 4 is in contact with the inner side wall of the cylinder 2, and the upper and lower ends of the cylinder 2 are respectively installed The upper end cover 1 and the lower end cover 6, the lower end cover sleeve 7 is sleeved on the inner side wall of the lower end cover 6, one end of the piston rod 11 is placed in the hollow cavity provided in the cylinder 2, and the other end of the piston rod 11 passes through the lower end cover shaft The sleeve 7 extends out of the hollow cavity provided in the cylinder 2, the hollow cavity of the piston rod 11 is penetrated with a wire rope 8, and the top of the wire rope 8 is distributed with external threads, and is fixed to the recess provided on the upper part of the piston rod 11 by a nut 13 In the groove, the lower part of the wire rope 8 passes through the hollow cavity of the piston rod 11 and is exposed outside the piston rod 11 to lift the load. The lower end cover sleeve 7 is provided with an annular air guide groove on the contact surface with the lower end cover 6 , And the lower end cover sleeve 7 is evenly distributed with a lower end cover throttle hole F, the lower end cover 6 is provided with a first air passage A, the lower end cover throttle hole F is connected to the first joint 9 through the first air passage A, and the lower end cover 6 An air cavity E is provided between the upper part of the piston rod 11 and the lower end cover 6 is also provided with a second air passage B. The air cavity E is connected to the second joint 10 through the second air passage B. The piston sleeve 4 and the piston rod 11 The contact surface of the piston rod is provided with an annular air guide groove, and the piston rod sleeve 3 is evenly distributed with a piston throttle hole D, the piston rod 11 is provided with a third air passage C, and the piston throttle hole D passes through the third air passage C and the air guide One end of the hose 15 is connected, and the other end of the air guiding hose 15 is connected with the third joint 15 installed on the upper end cover 1. In this embodiment, the piston rod sleeve 4 is evenly distributed with 16 piston rod throttle holes D. There are 16 lower end cover throttle holes F uniformly distributed on the lower end cover shaft sleeve.

[0013] In this embodiment, the contact surface between the nut 13 and the piston rod 11 is also provided with a tapered washer 3. A spherical washer 12 is also installed between the cone washer 3 and the nut 13. The use of spherical washers and tapered washers makes the wire rope exert less force when swinging, and can easily compensate for eccentricity and reduce the reaction force on the piston rod when swinging. Combined with the steel wire rope, the task of eccentricity compensation is more perfect. .

[0014] In this embodiment, the contact surface between the lower end cover 6 and the cylinder 2 is provided with a sealing ring 5.

[0015] In this embodiment, the piston rod sleeve 4 and the piston rod 11 are fixed together by interference fit. The lower end cover 6 and the lower end cover sleeve 7 are fixed together by interference fit.

[0016] In this embodiment, the first connector 9, the second connector 10, and the third connector 15 are all quick connectors.

[0017] The working principle of the present invention is as follows:

[0018] Air flotation mechanism: the first gas source ventilates the third joint 15 and the first joint 9 at the same time. When the gas enters the third joint 15, the gas enters the third air passage C through the hose 14, due to the outer surface of the end of the piston rod 11. There are two annular air guide grooves and square air guide grooves distributed up and down. The high-pressure gas finally enters the 16 orifices evenly distributed on the piston rod sleeve 4, because there is a gap between the cylinder block 2 and the piston sleeve 4. It is a clearance fit, so the gas flowing out of the piston rod orifice D can escape from the fit clearance. In this process of gas overflow, the space between the cylinder 2 and the piston sleeve 4 is filled with gas, so as to achieve the effect of gas suspension. In the same way, when the gas enters the first joint 9, the gas enters the lower end cover throttle hole F through the first air passage A and the gas communication groove on the outer surface of the lower end cover sleeve 7. There is a clearance fit with the pull rod part of the piston rod 11, and the high-pressure gas finally overflows through the fit clearance, and an air mold is formed in this process to achieve the effect of air suspension.

[0019] After the high-pressure gas is finally passed in, gas can be filled between the lower end cover sleeve 7 and the piston rod 11, and the cylinder 2 and the piston sleeve 4 to achieve relative gas isolation and gas suspension.

[0020] Lifting mechanism: When the second joint 10 is connected to the second gas source, the gas enters the gas channel B, and finally enters the sealed air chamber E. When the pressure of the gas is increased enough, the piston rod 11 and the piston sleeve 4 Jack up, drive the wire rope, complete the role of lifting and balancing the load.

[0021] The device of the invention can also adapt to a larger eccentricity, has better air suspension performance, more stable lifting performance, and more reliable, stable, perfect, professional, and focused work performance.
