[0026] Embodiment

[0027] As Figures 1 to 3 shown, the limit device for a ship hydraulic cylinder proposed by the present invention includes: a hydraulic cylinder 1, one end of the hydraulic cylinder 1 is fixedly provided with an insertion block 2, and the hydraulic cylinder 1 and the insertion block 2 are integrally formed to make the connection between them more stable. A limit groove 3 is opened on the outer wall of the insertion block 2, and a plurality of limit grooves 3 are opened; an installation seat 4 is provided at one end of the insertion block 2, and a plurality of support rods 5 are fixedly provided on one side of the installation seat 4. One end of the support rod 5 is fixedly provided with a card seat 6, which can stably support the card seat 6. The card seat 6 is movably inserted into the insertion block 2 for quick installation; a clamping component 7 for limiting the hydraulic cylinder 1 is arranged inside the card seat 6, which can quickly install and limit the hydraulic cylinder 1 to avoid shaking or displacement.

[0028] As shown Figures 3 to 5 in the figure, the clamping component 7 includes a fixed disk 71 arranged inside the card seat 6. One side of the fixed disk 71 is fixedly provided with a linkage rod 72, and the linkage rod 72 is rotatably connected to the card seat 6. One end of the linkage rod 72 is fixedly connected with a handle 73, and the outer wall of the handle 73 is provided with anti-slip lines to increase the friction of manual rotation. The other side of the fixed disk 71 is fixedly provided with a plurality of first fixing columns 74, and the positions of the first fixing columns 74 correspond to those of the limiting grooves 3. A connecting rod 75 is movably sleeved on the outer wall of the first fixing column 74. One end of the connecting rod 75 is movably sleeved with a sleeve rod 76. The upper end of the sleeve rod 76 is fixedly connected with a limiting block 77. A second fixing column 78 is movably sleeved on the limiting block 77. The upper end of the second fixing column 78 is fixedly connected with the inner wall of the card seat 6, which is convenient for the limiting block 77 to rotate and insert into the limiting groove 3, so as to quickly install and limit the hydraulic cylinder 1.

[0029] As shown Figure 3 and Figure 4 in the figure, a plurality of card slots 8 are opened at one end of the insertion block 2. A plurality of card blocks 9 corresponding to the card slots 8 are fixedly arranged on one side of the fixed disk 71, and the card slots 8 and the card blocks 9 can be stably clamped with each other after rotation, so as to limit the hydraulic cylinder 1, increase the connection stability between the insertion block 2 and the card seat 6, and at the same time limit the rotation angle of the fixed disk 71.

[0030] Furthermore, the upper end of the card block 9 is provided with a hook shape, which can stably clamp the card block 9 inside the card slot 8 and make the connection between the insertion block 2 and the card seat 6 more stable.

[0031] Secondly, a plurality of through holes 10 are opened on the mounting seat 4, which can pre-install the card seat 6, thereby improving the installation efficiency of the hydraulic cylinder 1.

[0032] Furthermore, an avoidance groove 11 for installing the clamping component 7 is opened inside the card seat 6, which can enable the clamping component 7 to rotate inside the card seat 6 and avoid causing obstruction.

[0033] The working principle of this embodiment is as follows: the mounting seat 4 is installed on the ship by means of bolts and through holes 10. Subsequently, the insertion block 2 at one end of the hydraulic cylinder 1 is inserted into the card seat 6, and during the insertion process, the card slot 8 on the insertion block 2 is opposite to the card block 9.

[0034] Further, after the insertion block 2 is inserted into the card seat 6, manually rotate the handle 73. The handle 73 drives the fixed disk 71 to rotate inside the card seat 6 through the linkage rod 72. The fixed disk 71 drives the first fixed column 74 to rotate. The first fixed column 74 drives the sleeve rod 76 to move through the connecting rod 75. The sleeve rod 76 drives the limiting block 77 to rotate on the outer wall of the second fixed column 78, so that one end of the second fixed column 78 rotates and is clamped into the limiting groove 3, which can quickly install and limit the hydraulic cylinder 1, avoiding the cumbersome process of installing bolts one by one, greatly saving the installation time, and being more convenient during maintenance and adjustment, which helps to improve the operation efficiency of ship mechanical equipment and reduce the maintenance cost.

[0035] Furthermore, during the rotation of the fixed disk 71, the clamping block 9 is simultaneously driven to rotate inside the clamping groove 8, so that the upper hook of the clamping block 9 is clamped into the inside of the clamping groove 8, which can limit the rotation angle of the clamping component 7 and make the insertion block 2 and the card seat 6 more stably connected, preventing unnecessary vibration and displacement of the equipment during operation.

[0036] The above specific embodiments are only several alternative embodiments of the present invention. Based on the technical solution of the present invention and the relevant revelations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
