[0002] In the hydraulic system of a ship, as an actuator, the hydraulic cylinder undertakes the important task of driving various mechanical devices of the ship. The support assembly of the hydraulic cylinder is a key part to ensure the stable operation of the hydraulic cylinder. It not only needs to provide sufficient supporting force for the hydraulic cylinder, but also ensure the stability and safety of the hydraulic cylinder in the complex sea conditions of the ship. In order to ensure the installation stability of the existing hydraulic cylinder, a support frame is installed around it to provide more stable support for the hydraulic cylinder, which leads to the formation of gaps at the contact between the support frame and the hydraulic cylinder. In the complex environment of the ship, dirt such as seawater, oil, and sediment easily enters these gaps, causing the hydraulic rod to drive these dirt into the interior of the hydraulic cylinder, damaging the internal components, making the hydraulic cylinder move smoothly, and even causing hydraulic system failures. For this reason, the utility model provides a support assembly for a ship hydraulic cylinder. Summary of the Utility Model

A rack 4 is fixedly arranged on one side of the connecting block 3, and the connecting block 3 and the rack 4 are welded; a fixed seat 5 is fixedly arranged on the upper surface of the bottom plate 1, and at least three fixed seats 5 are provided. A support rod 6 is rotatably arranged on the fixed seat 5, and a support assembly 7 for stably supporting the hydraulic cylinder 2 is arranged at the upper end of the support rod 6, increasing the stability of the hydraulic cylinder 2.

[0027] As Figures 2 to 4 shown, the support assembly 7 includes a support collar 71 movably sleeved on the outer wall of the piston rod of the hydraulic cylinder 2. An installation groove 72 is formed inside the support collar 71. Annular sliding grooves 73 are respectively formed on the upper and lower surfaces of the installation groove 72, and the annular sliding grooves 73 are symmetrically arranged. Annular sliders 74 are slidably arranged inside the annular sliding grooves 73. A fixed ring 75 is fixedly arranged between the annular sliders 74, which can limit and guide the fixed ring 75 to make the fixed ring 75 rotate stably. An inner annular brush 76 is fixedly sleeved on the inner ring surface of the fixed ring 75, and a first bevel gear 77 is fixedly sleeved on the outer ring surface of the fixed ring 75, which can drive the inner annular brush 76 to rotate, thereby cleaning the dust on the outer wall of the piston rod of the hydraulic cylinder 2 and providing stable support for the hydraulic cylinder 2 at the same time.

[0028] As Figures 2 to 4 shown, the support assembly 7 further includes a tooth column 78 rotatably arranged on the support collar 71. The tooth column 78 is meshed with the rack 4 and can drive the tooth column 78 to rotate. A second bevel gear 79 is fixedly arranged at one end of the tooth column 78.

[0029] Furthermore, a limit ring 8 is fixedly arranged on the upper surface of the bottom plate 1, which can position the bottom of the hydraulic cylinder 2 to prevent displacement.

[0030] Secondly, the rack 4 is arranged in an inverted "L" shape, which can be stably meshed with the tooth column 78, thereby driving the tooth column 78 to rotate stably.

[0031] Furthermore, installation holes 9 are respectively formed at the four corners of the bottom plate 1, which are convenient for quickly disassembling and assembling the bottom plate 1 with bolts.

[0032] The working principle of this embodiment is as follows: the piston rod of the hydraulic cylinder 2 is passed through from below the support collar 71, and then the connecting block 3 is welded to the end of the piston rod of the hydraulic cylinder 2. At the same time, the lower end of the hydraulic cylinder 2 is sleeved with the limit ring 8 on the bottom plate 1, thereby stably supporting the hydraulic cylinder 2. Subsequently, the hydraulic cylinder 2 is installed at the working position through the installation holes 9 on the bottom plate 1 in cooperation with bolts.

[0033] Further, during the operation of the hydraulic cylinder 2, the hydraulic cylinder 2 drives the connecting block 3 to move, the connecting block 3 drives the rack 4 to move, the rack 4 drives the tooth column 78 to rotate on the support collar 71, the tooth column 78 drives the second bevel gear 79 to rotate, the second bevel gear 79 drives the first bevel gear 77 to rotate, the first bevel gear 77 drives the fixed ring 75 to rotate, the fixed ring 75 drives the annular slider 74 to rotate in the annular chute 73, and at the same time the fixed ring 75 drives the inner annular brush 76 to rotate, so that the inner annular brush 76 rotates on the outer wall of the piston rod of the hydraulic cylinder 2 to remove the dirt on the outer wall of the hydraulic cylinder 2.

[0034] Furthermore, during the movement of the piston rod of the hydraulic cylinder 2, it will be guided and supported by the support collar 71, which increases the stability of the movement. Thus, while the hydraulic cylinder 2 is stably supported, the dirt on the outer wall of the piston rod of the hydraulic cylinder 2 is removed to prevent it from entering the interior of the hydraulic cylinder 2 and damaging the internal components, thereby improving the service life.

[0035] The above specific embodiments are only several alternative embodiments of the present invention.
