[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0020] Example 1: As Figures 1-3 As shown, this utility model provides a technical solution: a hazardous chemical loading and unloading platform, including a base plate 1, a loading and unloading platform 2, and a chemical storage tank 19. A first connecting member 3 is symmetrically fixedly installed at the bottom of the loading and unloading platform 2. A fixed plate 4 is symmetrically fixedly installed at the top of the base plate 1. A limiting rod 5 is symmetrically fixedly installed on the inner side of the fixed plate 4. A motor 6 is fixedly installed on the outer side of the fixed plate 4. A bidirectional lead screw 7 is fixedly installed at the output end of the motor 6. A sliding rod 8 is symmetrically threaded onto the outer wall of the bidirectional lead screw 7. Second connecting members 9 are fixedly installed at both ends of the sliding rod 8. A connecting rod 10 is rotatably connected to the outer wall of the second connecting member 9. First connecting blocks 11 are fixedly installed on both sides of the base plate 1. A guide rod 12 is fixedly installed on the top of the first connecting block 11. Second connecting blocks 13 are fixedly installed on both sides of the loading and unloading platform 2. The guide rod 12 and the second connecting block 13 are slidably connected. The sliding rod 8 and the limiting rod 5 are slidably connected. The first connecting member 3 and the connecting rod 10 are rotatably connected. Moving wheels 20 are symmetrically fixedly installed at the bottom of the base plate 1.
[0021] In this embodiment, by starting the motor 6, the output end of the motor 6 drives the bidirectional lead screw 7 to rotate. Since the outer wall of the bidirectional lead screw 7 is symmetrically threaded with sliding rods 8, according to the principle of thread transmission, when the bidirectional lead screw 7 rotates, the sliding rods 8 will move along the axial direction of the bidirectional lead screw 7. At the same time, the sliding rods 8 are slidably connected to the limiting round rods 5, which restrict the movement trajectory of the sliding rods 8, allowing them to move only in the horizontal direction. The second connecting parts 9, which are fixedly installed at both ends of the sliding rods 8, are rotatably connected to the connecting rods 10, while the other end of the connecting rods 10 is rotatably connected to the first connecting part 3. The first connecting part 3 is fixedly installed at the bottom of the loading and unloading platform 2. As the sliding rods 8 move horizontally, the connecting rods 10 will push the loading and unloading platform. 2. The guide rod 12 slides between itself and the second connecting block 13, providing stable guidance for the vertical movement of the loading and unloading platform 2. This allows for smooth adjustment of the platform's height. The design precisely controls the rotation of the bidirectional lead screw 7 by controlling the number of rotations of the motor 6, based on the height of the cargo compartments of different transport vehicles. This allows for precise adjustment of the platform's height, adapting to various types of vehicles and completely solving the problem of mismatched platform heights. This significantly improves loading and unloading efficiency. Furthermore, the smooth height adjustment process reduces the risk of hazardous chemicals falling or leaking due to excessive height differences during handling, lowers the difficulty for workers to handle heavy objects, and effectively prevents safety accidents caused by improper operation.
[0022] Example 2: As Figure 1 As shown, a top plate 14 is fixedly installed at the top of the guide rod 12, a threaded rod 15 is threadedly connected inside the top plate 14, a pressure plate 16 is rotatably connected to the bottom of the threaded rod 15, a limit post 17 is symmetrically fixedly installed at the top of the pressure plate 16, a throttle 18 is fixedly installed at the top of the threaded rod 15, and the limit post 17 is slidably connected to the top plate 14.
[0023] In this embodiment, by rotating the handle 18, the handle 18 drives the threaded rod 15 to rotate within the top plate 14. Since the threaded rod 15 is threadedly connected to the top plate 14, the threaded rod 15 will move axially during rotation. Since the bottom of the threaded rod 15 is rotatably connected to the pressure plate 16, its downward movement will push the pressure plate 16 closer to the chemical storage tank 19. The limiting posts 17 symmetrically installed on the top of the pressure plate 16 slide within the top plate 14, ensuring that the pressure plate 16 descends smoothly and vertically until the pressure plate 16 is tightly pressed against the top of the chemical storage tank 19. In this way, the displacement of the chemical storage tank 19 on the loading and unloading platform 2 can be effectively limited, and the stability of the chemical storage tank 19 during the transfer process can be improved.
[0024] The working principle of the embodiment is as follows: when the height of the loading and unloading platform 2 needs to be adjusted, the motor 6 is started, the output end of the motor 6 drives the bidirectional screw rod 7 to rotate, the outer wall of the bidirectional screw rod 7 is symmetrically connected with the sliding rod 8 through threads, according to the thread transmission principle, when the bidirectional screw rod 7 rotates, the sliding rod 8 moves along the axial direction of the bidirectional screw rod 7, at the same time, the sliding rod 8 is slidably connected with the limiting round rod 5, the limiting round rod 5 limits the movement track of the sliding rod 8, so that the sliding rod 8 can only move in the horizontal direction, the second connecting piece 9 fixedly installed at the two ends of the sliding rod 8 is rotatably connected with the connecting rod 10, and the other end of the connecting rod 10 is rotatably connected with the first connecting piece 3, the first connecting piece 3 is fixedly installed at the bottom of the loading and unloading platform 2, along with the horizontal movement of the sliding rod 8, the connecting rod 10 pushes the loading and unloading platform 2 to move up and down, and because the guide rod 12 is slidably connected with the second connecting block 13, the guide rod 12 can provide stable guiding for the up and down movement of the loading and unloading platform 2, so that the stable adjustment of the height of the loading and unloading platform 2 is realized, when the chemical storage tank 19 is evenly placed on the loading and unloading platform 2, the handle 18 can be rotated, the handle 18 drives the threaded rod 15 to rotate in the top plate 14, because the threaded rod 15 is threadedly connected with the top plate 14, the threaded rod 15 moves axially in the rotating process, because the bottom of the threaded rod 15 is rotatably connected with the pressing plate 16, the downward movement of the threaded rod 15 pushes the pressing plate 16 to move close to the chemical storage tank 19, the limiting columns 17 symmetrically installed at the top of the pressing plate 16 slide in the top plate 14, so that the stable and vertical downward movement of the pressing plate 16 is ensured, until the pressing plate 16 is tightly pressed on the top of the chemical storage tank 19, in this way, the displacement of the chemical storage tank 19 on the loading and unloading platform 2 can be effectively limited, and the stability of the chemical storage tank 19 in the transfer process is improved.
