The size of the pipe sleeve 11 can allow the end cover 7 and the piston rod 4 of the cylinder to enter. A plurality of clamping rods 12 for cooperating with the end cover 7 are provided on the side of the pipe sleeve 11 near the bottom. With this structure, when the rotating shaft 9 drives the pipe sleeve 11 to slide downward until the end cover 7 enters the interior of the pipe sleeve 11, the end cover 7 is clamped and fixed by the plurality of clamping rods 12, and then the power component drives the rotating shaft 9 to rotate, and simultaneously uses the operating rod 10 to control the rotating shaft 9 and the pipe sleeve 11 to slide upward, so that the end cover 7 is smoothly unscrewed from the end of the cylinder barrel 3, so as to realize the rapid disassembly of the end cover 7, and then the clamping rod 12 is loosened to remove the end cover 7, and the rotating shaft is continuously controlled by the operating rod 10. 9 and the pipe sleeve 11 are lowered until the top of the piston rod 4 enters the pipe sleeve 11.

In this process, no direct The replacement cylinder 16 is provided with a notch 17, and the notch 17 penetrates the side wall of the replacement cylinder 16. A cutter 18 used in conjunction with the old sealing ring 6 is connected to the replacement cylinder 16 at a position above the notch 17 in a transverse sliding manner. The cutter 18 passes through the inner wall of the replacement cylinder 16 and slides inward, so that when the rotating shaft 9 and the pipe sleeve 11 drive the piston rod 4 to slide downward into the replacement cylinder 16, the old sealing ring 6 is cut off by the transverse sliding of the cutter 18. When the piston 5 continues to slide downward to the notch 17, the old sealing ring 6 is removed. A conical column 19 is provided at the replacement cylinder 16, and the conical column 19 is put into the replacement cylinder 16 from the notch 17. The conical column 19 is slidably connected to the inside of the replacement cylinder 16. A new sealing ring 20 is sleeved on the outer side of the conical column 19. The new sealing ring 20 is sleeved on the conical column 19 from the bottom, and then put into the replacement cylinder 16 from the notch 17.

The interior of the operating table 1 is provided with a collection tank 21 connected to the bottom of the replacement cylinder 16. The collection tank 21 is used to collect the conical column 19 dropped from the replacement cylinder 16, so that the conical column 19 can be used again after being covered with a new sealing ring.

[0030] Preferably, refer to Figure 3 A slide groove 22 is provided inside the frame 2, and the slide groove 22 extends to the bottom of the frame 2. The rotating shaft 9 is vertically slidably connected in the slide groove 22, so that the rotating shaft 9 can slide downward along the slide groove 22 until it extends out from the bottom of the slide groove 22. A power groove 23 connected to the slide groove 22 is provided inside the frame 2, and the power assembly is arranged in the power groove 23. Such a structure can make the up and down sliding of the rotating shaft 9 more accurate, and the power assembly can be connected to the rotating shaft 9 in the slide groove 22 through the power groove 23, thereby ensuring the smoothness of the sliding and rotating movement of the rotating shaft 9.

[0031] Preferably, the operating rod 10 passes through the top of the slide groove 22 and is threadedly connected thereto. Such a structure only requires rotating the operating rod 10 to cause its bottom end to rotate downward under the action of the threaded connection. A connecting plate 24 is vertically slidably connected in the slide groove 22, and the bottom of the operating rod 10 is rotatably connected to the top of the connecting plate 24 via a bearing. In this way, when the bottom of the operating rod 10 rotates and slides downward, the connecting plate 24 rotatably connected thereto can be driven to slide downward, and the top of the rotating shaft 9 is rotatably connected to the bottom of the connecting plate 24 via a bearing. Such a structure enables the power component to drive the rotating shaft 9 to rotate freely relative to the connecting plate 24, so that the rotation and sliding of the rotating shaft 9 do not interfere with each other, thereby improving the convenience of disassembling the cylinder.

[0032] Preferably, a plurality of guide posts 25 are welded or bolted to the top of the connecting plate 24, and the guide posts 25 pass through the top of the slide groove 22 and are slidably connected thereto. The plurality of guide posts 25 are arranged to provide guidance for the up and down sliding of the connecting plate 24, so that it can only slide up and down, thereby ensuring accurate control of the up and down sliding of the rotating shaft 9.

[0033] Preferably, refer to Figure 4The power assembly includes a motor 26, a driving gear 27, and a driven gear 28. The motor 26 is welded or fixed in the power slot 23 by bolts. The driving gear 27 is welded or fixed on the output shaft of the motor 26 by bolts. The driven gear 28 is rotatably connected in the slide slot 22 and meshes with the driving gear 27. Such a structure can drive the driving gear 27 to rotate when the motor 26 is started, and drive the driven gear 28 meshing with the driving gear 27 to rotate. The rotating shaft 9 vertically penetrates the driven gear 28 and is slidably connected thereto. A limiting bar 29 used to cooperate with the driven gear 28 is provided on the rotating shaft 9. Under the action of the limiting bar 29, the rotating shaft 9 can only slide up and down relative to the driven gear 28. When the driven gear 28 rotates, the rotating shaft 9 is driven to rotate synchronously, thereby ensuring that the rotating shaft 9 can rotate freely while ensuring the up and down sliding movement of the rotating shaft 9, thereby ensuring the smoothness of the rotation and disassembly of the end cover 7.

[0034] Preferably, refer to Figure 6 A guide ring 30 is welded or fixed by bolts in the slide groove 22, and a guide bar 31 is welded or integrally formed and fixed on the driven gear 28. The guide bar 31 is rotatably connected in the guide ring 30. Such a structure enables the driven gear 28 to be firmly rotatably connected in the slide groove 22 under the rotation cooperation of the guide bar 31 and the guide ring 30. When the rotating shaft 9 slides up and down, the driven gear 28 will not be driven to move up and down, thereby ensuring the firmness of the meshing connection between the driven gear 28 and the driving gear 27, and ensuring the stability of the rotation drive structure of the rotating shaft 9.

[0035] Preferably, refer to Figure 5 The inner wall of the sleeve 11 is rotatably connected with a plurality of clamping wheels 32 through bearings. The clamping wheels 32 are made of rubber material and will not scratch the piston rod 4. The clamping wheels 32 are in rotational contact with the side wall of the piston rod 4. Such a structure enables the piston rod 4 to roll in contact with the plurality of clamping wheels 32 on the side wall of the sleeve 11 after entering the interior of the sleeve 11, thereby limiting the position of the piston rod 4 while avoiding scratches on the piston rod 4, thereby ensuring the integrity of the piston rod 4 in subsequent operation steps.

[0036] Preferably, the clamping rod 12 passes through the side wall of the pipe sleeve 11 and is threadedly connected thereto, and the end of the clamping rod 12 contacts the side of the end cover 7. Such a structure only requires rotating the clamping rod 12 to control the clamping rod 12 to move forward or backward, thereby achieving clamping, fixing or separation of the end cover 7. The structure is simple and easy to operate, and it is more convenient to use with the end cover 7 during the disassembly process of the end cover 7.

[0037] Preferably, a telescopic rod 33 is provided on the side wall of the replacement cylinder 16, which can be a pneumatic cylinder or an oil cylinder. The cutter 18 is welded or integrally formed and fixed to the movable end of the telescopic rod 33. A pressure sensor used in conjunction with the old sealing ring 6 is provided in the replacement cylinder 16. When the rotating shaft 9 and the pipe sleeve 11 drive the piston rod 4 to move downward into the replacement cylinder 16, the pressure sensor generates a signal due to the squeezing of the old sealing ring 6 on the piston 5. The pressure sensor is electrically connected to the telescopic rod 33. After the signal is transmitted to the telescopic rod 33, the telescopic rod 33 performs a telescopic movement, which drives the cutter 18 to move toward the inside of the replacement cylinder 16 to cut off the old sealing ring 6 at the corresponding position, thereby making the removal of the old sealing ring 6 more efficient and convenient.

[0038] Preferably, a hand wheel 34 is welded or integrally formed on the top of the operating rod 10. The setting of the hand wheel 34 allows the operating rod 10 to be rotated with one hand, so that the operator can drive the rotating shaft 9 to slide downward while performing other operations, further improving the convenience of replacing the sealing ring.
