Detailed implementation method: The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figure 1-9 One embodiment of the present invention is a liftable multi-functional engine room maintenance platform, including a deck 1 for marine engineering drilling platforms and ship outfitting construction; Steel slide rail ear plate 2, four sets of steel slide rail ear plates 2 are provided, and the four sets of steel slide rail ear plates 2 are fixedly installed on the lower side of the deck 1; The lifting assembly is movably installed in two sets of close steel slide rail ear plates 2. The upper end of the lifting assembly is movably inserted into the front opening of the deck 1. The lifting assembly is used to provide up and down lifting function when maintaining mechanical equipment at different heights. The sliding component is movably installed on the upper side of the lifting component. The sliding component is used to slide closer to the mechanical equipment when the lifting component is raised and lowered to be level with the mechanical equipment. This device allows the lifting platform to slide up and down or move back and forth through the lifting component and the sliding component, making it convenient for maintenance personnel to maintain mechanical equipment at different heights or mechanical equipment far away from the lifting platform. Furthermore, the lifting assembly includes two sets of toothed grooves 3, which are formed within two sets of adjacent steel slide rail ear plates 2. Each of the front and rear ends of the two sets of steel slide rail ear plates 2 has a first slide groove 4. Stainless steel pins 5 are slidably inserted into each of the four sets of first slide grooves 4. Steel connecting ear plates 6 are installed on opposite sides of each of the four sets of stainless steel pins 5. A connecting rod 7 is fixedly installed between the two sets of steel connecting ear plates 6. A bidirectional motor 8 is fixedly installed within the connecting rod 7. Rotary shafts 9 are fixedly installed on the output ends of both sides of the bidirectional motor 8. The two sets of rotating shafts 9 are rotatably inserted into the toothed grooves. Inside the groove 3, two sets of rotating shafts 9 are inserted into one end of the groove 3 and gears 10 are fixedly installed. The gears 10 mesh with the teeth in the groove 3. The upper ends of the two sets of steel connecting ear plates 6 are fixedly installed with the first fixed grid platform 11. This structure drives the two sets of gears 10 to rotate and move in the groove 3 through the bidirectional motor 8, thereby driving the steel connecting ear plates 6 and the first fixed grid platform 11 to move up and down, so that the first fixed grid platform 11 can be aligned with mechanical equipment of different heights, which facilitates the maintenance personnel on the first fixed grid platform 11 to maintain mechanical equipment of different heights.

[0018] Furthermore, the sliding assembly includes a second fixed grid platform 12, which is movably mounted on the upper side of the first fixed grid platform 11. A third slide groove 15 is provided in the upper side of the first fixed grid platform 11, and a screw 16 is rotatably installed in the third slide groove 15. A slider 17 is provided on the lower side of the second fixed grid platform 12, and the slider 17 is threadedly connected to the screw 16. A servo motor 18 is fixedly installed in the lower front end of the first fixed grid platform 11. Synchronous pulleys 19 are fixedly installed on the front end of the screw 16 and the output end of the servo motor 18. Synchronous belts 20 are sleeved on the two sets of synchronous pulleys 19. This structure allows the second fixed grid platform 12 to slide on the first fixed grid platform 11 and approach the mechanical equipment by rotating the screw 16 driven by the rotation of the servo motor 18. This allows maintenance personnel standing on the second fixed grid platform 12 to approach the mechanical equipment, improving the convenience of maintenance personnel for maintaining the mechanical equipment.

[0019] Furthermore, support plates 13 are fixedly installed on the lower sides of both the left and right ends of the second fixed grid platform 12, and second sliding grooves 14 are opened on the upper and lower sides of both the left and right ends of the first fixed grid platform 11. The two sets of support plates 13 are movably inserted into the second sliding grooves 14. When the second fixed grid platform 12 slides on the first fixed grid platform 11, the support plates 13 slide in the second sliding grooves 14, which improves the sliding connection effect of the second fixed grid platform 12 on the first fixed grid platform 11, can prevent the second fixed grid platform 12 from sliding off the first fixed grid platform 11, and can prevent the second fixed grid platform 12 from having poor support effect when the first fixed grid platform 11 slides out.

[0020] Furthermore, railings 21 are installed on all four sides of the upper end of the second fixed grid platform 12. The railings 21 on the front and rear sides of the upper end of the second fixed grid platform 12 are slidably connected on the second fixed grid platform 12. This structure allows the railings 21 to slide on the second fixed grid platform 12, so that when maintenance personnel stand on the second fixed grid platform 12, the front and rear sides of the maintenance personnel can be protected, preventing the maintenance personnel from slipping off the second fixed grid platform 12.

[0021] Furthermore, a groove 22 is provided in the left end of the second fixed grid platform 12, and a safety rod 23 is fixedly installed in the groove 22. The safety rod 23 is made of tungsten steel. This structure locks the safety rod 23 in the groove 22, so that the maintenance personnel can ensure the safety of the maintenance personnel on the second fixed grid platform 12 when maintaining the mechanical equipment.

[0022] Furthermore, a movable groove 24 is provided in the left end of the second fixed grid platform 12. A spring 25 is installed in the movable groove 24. A sealing plate 26 is movably installed at the left end opening of the movable groove 24. The left end of the sealing plate 26 is inserted into the upper opening of the groove 22. An elastic rope 28 is fixedly installed on the right side of the sealing plate 26. The right end of the elastic rope 28 is connected to the fence 21 on the rear side of the second fixed grid platform 12. This structure, under the action of the spring 25, pops the sealing plate 26 out and inserts it into the upper opening of the groove 22, thereby sealing and protecting the safety rod 23 in the groove 22, preventing seawater from entering the groove 22 and corroding the safety rod 23, and improving the service life of the safety rod 23.

[0023] Furthermore, a sealing gasket 27 is glued to the upper side of the sealing plate 26. The sealing plate 26 and the sealing gasket 27 are larger than the upper opening of the groove 22. This structure prevents seawater from flowing into the groove 22 through the gap at the connection between the sealing plate 26 and the groove 22 and causing corrosion to the safety rod 23 by sealing the sealing plate 26 inserted into the upper opening of the groove 22 through the sealing gasket 27 on the upper side of the sealing plate 26.

[0024] Furthermore, fixed ear plates 29 are fixedly installed on both sides of the front opening of the deck 1 and on the two sets of steel slide rail ear plates 2. Stainless steel bolts and nuts 30 are threaded into the fixed ear plates 29. The fixed ear plates 29 are in contact with the first fixed grid platform 11. This structure can ensure the stability of the first fixed grid platform 11 at different heights when the first fixed grid platform 11 and the second fixed grid platform 12 are lowered to different heights by the elastic rope 28 and the fixed ear plates 29, and prevent the first fixed grid platform 11 from loosening after it has moved. Working principle: When maintaining mechanical equipment, such as... Figure 6 and Figure 9As shown, first, the fence 21 is slid open. The sliding of the fence 21 moves the elastic rope 28, which in turn moves the sealing plate 26 and sealing gasket 27 into the movable groove 24. The sealing plate 26 also compresses the spring 25. When the sealing plate 26 slides into the movable groove 24, it opens the upper opening of the groove 22. Then, the maintenance personnel stand on the second fixed grid platform 12 and fasten the safety lock on their safety suit to the safety bar 23 in the groove 22. Then, the fence 21 is closed. Under the recoil of the spring 25, the sealing plate 26 and sealing gasket 27 in the movable groove 24 pop out and insert into the upper opening of the groove 22, sealing the groove 22. Figure 3 and Figure 5 As shown, the bidirectional motor 8 inside the connecting rod 7 is then started. The output ends of the bidirectional motor 8 at both ends drive the rotating shaft 9 to rotate. The two sets of rotating shafts 9 drive the two sets of gears 10 to rotate in the tooth groove 3. The gears 10 rotate and slide up and down in the tooth groove 3, thereby moving the two sets of steel connecting ear plates 6, the first fixed grid platform 11 and the second fixed grid platform 12 downward. When the two sets of steel connecting ear plates 6 slide, they drive the stainless steel pin pin 5 to slide in the first slide groove 4, preventing the steel connecting ear plates 6 from rotating on the steel slide rail ear plates 2. After the steel connecting ear plates 6 drive the first fixed grid platform 11 and the second fixed grid platform 12 to rise and fall until they move, the fixed ear plate 29 is attached to the left and right sides of the first fixed grid platform 11. Then, the stainless steel bolts and nuts 30 are inserted into the fixed ear plate 29 to fix the fixed ear plate 29 to the first fixed grid platform 11, thereby preventing the first fixed grid platform 11 and the second fixed grid platform 12 from not moving. When the system is in motion, no movement occurs, allowing for maintenance of mechanical equipment. For maintenance of mechanical equipment located far from the second fixed grid platform 12, the servo motor 18 is activated. The output of the servo motor 18 rotates, driving the synchronous pulley 19 to rotate. The synchronous pulley 19 rotates, driving the synchronous belt 20 to rotate. The synchronous belt 20 then rotates, driving the synchronous pulley 19 mounted on the screw 16 to rotate. The rotation of the synchronous pulley 19 causes the screw 16 to rotate, which in turn causes the slider 17 to slide within the third slide groove 15. The sliding of the slider 17 causes the second fixed grid platform 12 to slide and unfold on the first fixed grid platform 11. When the second fixed grid platform 12 unfolds, it causes the two sets of support plates 13 to slide within the second slide groove 14 on the first fixed grid platform 11. After the second fixed grid platform 12 is unfolded on the first fixed grid platform 11, maintenance of the more distant mechanical equipment can be performed. This is the complete working principle of the present invention.
