[0027] The supporting mechanism 2 comprises a limiting plate 201 slidably installed in the inner cavity of the fixed frame 1, one side of the limiting plate 201 is fixedly connected with a handle 202, the other side of the limiting plate 201 is fixedly connected with a bearing plate 203, the bottom of the bearing plate 203 is in contact with the inner wall of the fixed frame 1, the top of the bearing plate 203 is fixedly installed with a second hydraulic cylinder 204, the output end of the second hydraulic cylinder 204 is fixedly connected with a positioning plate 205; by arranging the supporting mechanism 2, the bottom of the marine engine part can be supported and positioned, so that the stability of the marine engine part maintenance is improved, and after the marine engine part is hoisted, the fixed frame 1 is rotated, so that other parts of the marine engine part are exposed to the workers, thereby facilitating the workers to maintain and repair.
[0028] With reference to Figure 2 and Figure 4 , the two sides of the limiting plate 201 are fixedly connected with dovetail blocks 206, and the inner cavity of the fixed frame 1 is provided with dovetail grooves 10 matched with the dovetail blocks 206; by arranging the dovetail blocks 206 and the dovetail grooves 10, the limiting plate 201 can be limited, so that the stability of the transverse movement of the limiting plate 201 is improved.
[0029] With reference to Figure 4 , the other side of the limiting plate 201 is fixedly connected with a retaining link 207, and the bottom of the retaining link 207 is fixedly connected with the top of the bearing plate 203; by arranging the retaining link 207, the stability between the bearing plate 203 and the limiting plate 201 is improved, and the position deviation of the bearing plate 203 is avoided.
[0030] With reference to Figure 4 and Figure 5 , the top of the positioning plate 205 is fixedly connected with a protective pad 208, and the material of the protective pad 208 is rubber; by arranging the protective pad 208 made of rubber, the marine engine part can be protected, and the surface wear of the marine engine part caused by the positioning of the positioning plate 205 is avoided.
[0031] With reference to Figure 4 and Figure 5 , the bottom of the bearing plate 203 is fixedly connected with a lead screw 209, the surface of the lead screw 209 is threadedly connected with a threaded sleeve 210, and the bottom of the threaded sleeve 210 is fixedly connected with a fixed block 211; by arranging the lead screw 209, the threaded sleeve 210 and the fixed block 211, the bottom of the bearing plate 203 can be supported, so that the stability of the use of the second hydraulic cylinder 204 is improved.
[0032] With reference to Figure 3The bottom of the circular plate 4 is fixedly connected to a limiting ring 11, and the top of the fixed plate 3 is provided with a limiting groove 12 for use with the limiting ring 11. By setting the limiting ring 11 and the limiting groove 12 to cooperate, when the fixed plate 3 rotates with the fixed frame 1, the circular plate 4 still maintains its initial state and will not rotate with the fixed frame 1.
[0033] Reference Figure 3 A positioning sleeve 13 is fixedly sleeved on the surface of the output end of the first hydraulic cylinder 5, and the bottom of the positioning sleeve 13 is fixedly connected to the top of the connecting frame 6. By setting the positioning sleeve 13, the stability between the output end of the first hydraulic cylinder 5 and the connecting frame 6 can be improved, and the connecting frame 6 can be prevented from falling off during use.
[0034] Working principle: In use, the operator starts the first hydraulic cylinder 5 using an external control switch. The output end of the first hydraulic cylinder 5 drives the connecting frame 6 to move downward. As the connecting frame 6 moves downward, it drives the steel cable 7 downward. After the steel cable 7 moves to the designated position, the operator uses the hook 8 to fix the ship's engine parts. Then, the operator starts the first hydraulic cylinder 5, causing it to drive the ship's engine parts upward. When the ship's engine parts move upward to the designated position, the operator pushes the two limit plates 201 to move in opposite directions. As the two limit plates 201 move in opposite directions, they drive the two bearing plates 203 to move in opposite directions. As the two bearing plates 203 move in opposite directions, they drive the two second hydraulic cylinders 204 to move in opposite directions. When the second hydraulic cylinders 204 move to the designated position, the operator rotates the threaded sleeve 210. The threaded sleeve 210 rotates on the surface of the lead screw 209 and moves downward. As the threaded sleeve 210 moves downward, it drives the fixing block 211 to move downward. After the fixed block 211 moves downward and contacts the ground, the staff uses an external control switch to start the second hydraulic cylinder 204. The output end of the second hydraulic cylinder 204 drives the positioning plate 205 to move upward. When the positioning plate 205 moves upward, it drives the protective pad 208 to move upward. After the protective pad 208 moves upward and contacts the bottom of the ship's engine parts, it can support and position them, thereby improving the stability of the maintenance of the ship's engine parts. Since the gap between the two sides of the ship's engine parts and the fixed frame 1 is small, it is not conducive to the staff's maintenance. When the staff needs to maintain the two ends of the ship's engine parts, the support mechanism 2 is first put away, and then the fixed frame 1 is rotated. The fixed frame 1 drives the pulley 9 to rotate around the axis of the first hydraulic cylinder 5. Since the ship's engine parts are installed at the bottom of the steel cable 7, the angle of the ship's engine parts does not change under the influence of gravity, while the angle of the fixed frame 1 changes, so that the two ends of the ship's engine parts are exposed, thereby providing space for the staff to maintain them.
[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
