[0030] The technical means adopted to achieve the intended purpose of this utility model will be further described below with reference to the accompanying drawings of the embodiments of this utility model.

[0031] See Figure 1 A multi-functional modular maintenance system for large marine hydraulic cylinders includes a cylinder fixing rod 1 and a piston rod support rod 2, which are coaxially connected from bottom to top, and a traction rope assembly 3.

[0032] The cylinder fixing rod 1 is provided with a clamp 11, which includes an upper connector and a lower connector. The lower connector is connected to the cylinder fixing rod 1, and the upper connector and the lower connector are detachably attached to the outside of the cylinder.

[0033] A fixing member 12 for connecting one end of the traction device 4 is provided on the side of the cylinder fixing rod 1 opposite to the clamp 11.

[0034] The piston rod support rod 2 has a piston rod support 21 at its lower part. The piston rod support 21 is arranged in the same direction as the clamp 11. The top of the piston rod support rod 2 is rotatably connected to the first guide wheel 23 and the second guide wheel 25. The first guide wheel 23 is arranged on the same side as the piston rod support 21, and the second guide wheel 25 is arranged on the side opposite to the first guide wheel 23.

[0035] The traction rope assembly 3 includes a traction rope, one end of which passes around the first guide wheel 23 and is detachably connected to the piston rod, and the other end passes around the second guide wheel 25 and is connected to the traction device 4.

[0036] The traction device 4 can be a hand-operated hoist. One end of the hook is connected to the traction rope, and one end of the hoist's wire rope is connected to the fixing component 12. The other end is pulled by a person or machine, causing the traction rope to move downwards. This moves the end of the traction rope connected to the piston rod upwards, dragging the piston rod upwards and separating it from the cylinder. This facilitates cleaning and other maintenance operations on the cylinder. Furthermore, using a hand-operated hoist in conjunction with a machine can increase the traction force significantly, reduce the difficulty of manually disassembling the piston rod and cylinder, and improve disassembly efficiency.

[0037] See Figure 1 The cylinder fixing rod 1 and the piston rod support rod 2 are fixedly connected by flanges located at their ends, and one side of the flanges is hinged. In actual use, the flanges of the cylinder fixing rod 1 and the piston rod support rod 2 are aligned and then fixed together with bolts. When not in use, the bolts are removed, the cylinder fixing rod 1 and the piston rod support rod 2 are folded in half, and the connection is maintained by the hinges, making it easy to store and move.

[0038] See Figure 2 The lower connecting member includes a support rod extending in the direction of the vertical cylinder fixing rod 1 axis and a lower clamp connected to the top of the support rod.

[0039] Furthermore, the lower clamp has the same structure as the upper connector, with an arc-shaped middle section and symmetrical connecting plates at both ends. The connecting plates are provided with connecting holes 313. In use, the lower clamp is connected to the upper connector and attached to the outside of the cylinder by bolting through the connecting holes 313, thereby fixing the cylinder to the cylinder fixing rod 1.

[0040] See Figure 1 Multiple clamps 11 are spaced apart along the axial direction of the cylinder fixing rod 1, and multiple piston rod supports 21 are spaced apart along the axial direction of the piston rod support rod 2. The purpose is to improve the stability of fixing and support.

[0041] See Figure 1 and Figure 3The piston rod support 21 includes a support rod extending axially from the piston rod support rod 2 and an arc-shaped support member fixed to the top of the support rod. The inner dimensions of the support member are matched with the dimensions of the piston rod.

[0042] See Figure 2 and Figure 3 To prevent wear on the piston rod from the clamp 11 or piston rod support 21, an elastic pad is provided on the inner side of the arc-shaped support. Specifically, multiple circular rubber pads can be evenly distributed on the inner surface of the arc-shaped support. Rubber pads can also be provided on the lower clamp and upper connecting parts to prevent cylinder wear.

[0043] See Figure 4 The traction rope assembly 3 also includes a piston rod connector 31. The piston rod connector 31 includes a groove-shaped connecting body 311 with an open lower end in its cross-section, and a detachable pin 312 that passes through the two side walls of the connecting body 311 and forms a closed space with the connecting body 311. The upper end of the connecting body 311 is provided with a connecting hole 313 for connecting with the traction rope. When it is necessary to connect with the piston rod, first remove the pin 312, insert the lug of the piston rod into the groove of the connecting body 311, and then insert and tighten the pin 312 to achieve a detachable connection with the piston rod.
