Description

Technical Field

[0001] This utility model relates to the field of marine storage tank positioning technology, specifically a positioning tool for marine sulfuric acid and mixed liquid storage tanks. Background Technology

[0002] During ship operation, sulfuric acid and its mixtures are important industrial media that often need to be stored and transported in specialized tanks. Due to the special environment of ship navigation, which is not only limited by space but also subject to continuous turbulence and swaying caused by wind and waves, the installation and positioning accuracy and stability of marine sulfuric acid and its mixture storage tanks are directly related to the safety and reliability of ship operation. This places extremely high demands on the positioning fixtures.

[0003] Currently, the existing positioning fixtures for marine sulfuric acid and mixed liquid storage tanks in the industry generally adopt traditional mechanical positioning and installation methods. These fixtures typically rely on mechanical structures such as bolts, clips, and manually adjustable supports to fix and position the storage tanks. During the installation phase, operators first need to use hoisting equipment to initially place the storage tank in the fixture area. Then, multiple people work together to manually adjust the position of the storage tank to align it with the preset installation benchmark. Then, they tighten the bolts or fasten the clips one by one. During this process, they also need to repeatedly use tools such as levels and measuring tapes to check the positional accuracy. If there is any deviation, they need to disassemble and readjust. During the unloading phase, the bolts, clips, and other fasteners need to be removed one by one in the reverse process. If there is any rust on the bolts or jamming of the clips, additional rust removal tools or forceful disassembly are required, further extending the unloading time.

[0004] This mechanical positioning and installation method has certain drawbacks. The loading and unloading process not only requires a lot of manpower and the operation steps are cumbersome and complicated, but it is also easy for human operation errors to affect the positioning accuracy. Moreover, in the limited operating space of the ship, the complicated operation process will greatly increase the difficulty of the operation, resulting in low loading and unloading efficiency. In severe cases, the operation time may even affect the overall operation and scheduling of the ship, which cannot meet the needs of modern ships for efficient and convenient operation. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a positioning fixture for marine sulfuric acid and mixed liquid storage tanks.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A positioning fixture for a marine sulfuric acid and mixed liquid storage tank includes: a positioning base, clamping components fixedly mounted on both the left and right sides of the positioning base, the clamping components being hollow, rollers mounted on the four corners of the clamping components, locking elements mounted on the axles of the rollers, a fixed seat fixedly mounted between the bottoms of the clamping components on the front and rear sides, a sliding rod mounted on the fixed seat, a groove in the center of the bottom of the positioning base, an elliptical sliding rod fixedly mounted on the groove, and a magnetic attraction moving positioning component movably mounted on the elliptical sliding rod and the sliding rod. The clamping components are used to place the marine sulfuric acid and mixed liquid storage tank onto the rollers, and the magnetic attraction moving positioning component is used to move one end of the marine sulfuric acid and mixed liquid storage tank to the clamping component on the other side, thereby fixing the marine sulfuric acid and mixed liquid storage tank by magnetic force. The magnetic moving positioning assembly includes a moving kit and a moving plate. An elliptical through-hole is located at the center of the bottom of the moving plate. Electromagnetic balls are located on the left and right sides of the top of the moving plate. A driver is mounted on the rotating shaft of each electromagnetic ball. The driver is electrically connected to an external power source and is used to energize the electromagnetic balls to fix the marine sulfuric acid and mixed liquid storage tank. The elliptical through-hole cooperates with an elliptical slide rod to allow the moving plate to slide left and right on the elliptical slide rod. Two sets of moving plates are mounted on the elliptical slide rod, and a moving kit is fixed between the moving plates. Sliding sleeves are located on the front and rear sides of the moving kit, slidingly engaging with the slide rod. The sliding sleeves and slide rod serve as guides when the moving plates move.

[0007] Preferably, the locking element is used to lock the rollers after the marine sulfuric acid and mixture storage tank is secured.

[0008] Preferably, a buffer layer is provided on the inner wall of the clamping assembly, and the surface of the buffer layer is provided with anti-slip texture. The buffer layer is used to protect the marine sulfuric acid and mixed liquid storage tank and enhance friction during the clamping process.

[0009] Compared with the prior art, this utility model provides a positioning fixture for marine sulfuric acid and mixed liquid storage tanks, which has the following beneficial effects: With the clamping assembly and magnetic positioning assembly, the operator only needs to place the tank on the rollers of one side of the clamping assembly. There's no need for manual pushing or adjusting the tank's initial position; the rollers easily support the tank and reduce movement resistance. Then, the magnetic positioning assembly allows for precise movement and fixation of the tank. The moving plate, with the cooperation of the elliptical through-hole and elliptical slide rod, and the guidance of the sliding sleeve and slide rod of the moving kit, stably moves the electromagnetic ball closer to the tank. Once the driver controls the electromagnetic ball to be energized, it quickly magnetically attracts and fixes the tank, simultaneously moving it along the rollers to the other side of the clamping assembly. After positioning, the locking mechanism locks the rollers. The entire installation process eliminates the need for repeated disassembly and tightening of mechanical fasteners, reducing operational steps. A single person can complete the core operations, shortening installation time.

[0010] During the unloading phase, there is no need to remove the bolts, clips, and other parts of traditional mechanical tooling one by one. Simply unlock the rollers by first releasing the locking mechanism, and then control the driver to cut off the power to the electromagnetic ball, so that the magnetic attraction and fixing effect disappears. At this time, the tank can slide easily with the support of the rollers. The operator only needs to apply slight force to remove the tank from the clamping assembly, avoiding the unloading difficulties caused by the corrosion and jamming of mechanical fasteners. The entire unloading process is simple to operate and short in time, effectively reducing the difficulty of unloading and reducing the manpower input. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Reference Figures 1-5 As shown, the positioning fixture for a marine sulfuric acid and mixed liquid storage tank in this embodiment includes a positioning base 1. The positioning base 1 serves as the basic support component of the entire fixture, providing a stable installation carrier for other components. Its structural strength is specially designed to withstand the weight of the storage tank and the internal medium, and to adapt to the turbulent environment of the ship.

[0015] The left and right sides of the positioning base 1 are fixedly connected to the clamping assembly 2. This fixed connection method ensures that the clamping assembly 2 will not shift during use, guaranteeing stable clamping of the storage tank. The clamping assembly 2 adopts a hollow structure design, and the size of the hollow space matches the outer diameter of common marine sulfuric acid and mixed liquid storage tanks, which can just accommodate the storage tank for positioning operations. Rollers 203 are provided at the four corners of the clamping assembly 2. The rollers 203 are connected to the inner wall of the clamping assembly 2 through rotating shafts. The rotation smoothness of the rotating shafts has been optimized to reduce the frictional resistance when the storage tank moves.

[0016] The bottom of the clamping components 2 on both the front and rear sides is fixedly connected to the fixed base 201. The top of the fixed base 201 is fixedly connected to the slide rod 202. The slide rod 202 is made of high-strength metal and its surface is polished to reduce wear during subsequent sliding. A groove is provided in the center of the bottom of the positioning base 1. The inner wall of the groove is fixedly connected to the elliptical slide rod 101. The cross-section of the elliptical slide rod 101 is elliptical to prevent the subsequent moving plate 303 from rotating or shifting.

[0017] A magnetic suction moving positioning component 3 is movably mounted on the elliptical slide rod 101 and slide rod 202. The moving plate 303 in the magnetic suction moving positioning component 3 has an elliptical through hole 305 at the center of its bottom. The size of the elliptical through hole 305 is adapted to the elliptical slide rod 101 to ensure that the moving plate 303 can slide smoothly along the elliptical slide rod 101. The left and right sides of the top of the moving plate 303 are connected to the rotating shaft of the electromagnetic ball 302. A driver 304 is installed on the rotating shaft of the electromagnetic ball 302. The driver 304 is electrically connected to an external power source through wires and can quickly control the power on and off of the electromagnetic ball 302.

[0018] Two sets of movable plates 303 are installed on the elliptical slide rod 101. The two sets of movable plates 303 are fixedly connected to the movable kit 301. Sliding sleeves are installed on both the front and rear sides of the movable kit 301. The inner diameter of the sliding sleeves matches the outer diameter of the slide rod 202. The sliding sleeves can slide along the slide rod 202 to provide guidance for the movement of the movable plates 303. A buffer layer 205 is pasted on the inner wall of the clamping assembly 2. The buffer layer 205 is made of elastic rubber material and has anti-slip texture pressed on the surface, which can protect the outer wall of the storage tank and enhance the clamping stability.

[0019] In some examples, a locking element 204 is installed on the shaft of the roller 203. The locking element 204 adopts a snap-fit ​​structure design. After the storage tank is positioned and fixed, the operator can manually move the locking element 204 to lock the shaft of the roller 203, preventing the roller 203 from rotating accidentally, further improving the stability of the storage tank after it is fixed, and avoiding displacement of the storage tank due to ship turbulence.

[0020] In some examples, the surface of the electromagnetic ball 302 is covered with a wear-resistant protective layer made of ceramic material, which has high hardness and corrosion resistance. This prevents the electromagnetic ball 302 from wearing or rusting during contact with the storage tank or during long-term use, ensuring the long-term stability of the magnetic adsorption effect of the electromagnetic ball 302.

[0021] In some examples, limit blocks are installed at both ends of the slide bar 202. The limit blocks are fixed to the ends of the slide bar 202 with bolts. This prevents the sliding sleeve on the moving kit 301 from falling off the ends of the slide bar 202 during the sliding process. At the same time, it can limit the range of movement of the moving plate 303 and avoid excessive movement of the moving plate 303, which could cause the components to collide and be damaged.

[0022] The working principle of this utility model is as follows: When using this positioning fixture for marine sulfuric acid and mixed liquid storage tanks, the first step is to prepare for its installation. Based on the pre-set installation position of the tank on the ship, the positioning base 1 is placed stably, utilizing its high-strength structure to ensure stability in the turbulent environment of the ship. Clamping components 2 are pre-fixed to the left and right sides of the positioning base 1. The bottoms of the clamping components 2 on the front and rear sides are connected as a whole by a fixing seat 201. The sliding rod 202 at the top of the fixing seat 201 is made of high-strength metal and has a polished surface. The elliptical sliding rod 101 in the central groove at the bottom of the positioning base 1 cooperates with the sliding rod 202, providing a basic guiding structure for the subsequent movement of the magnetically movable positioning component 3. Meanwhile, it was confirmed that the buffer layer 205 on the inner wall of the clamping assembly 2 was undamaged, the anti-slip texture on its surface was clear, the roller 203 rotated smoothly, the locking part 204 was in the unlocked state, the moving plate 303 of the magnetic moving positioning assembly 3 was movably connected to the elliptical slide rod 101 through the elliptical through hole 305, the sliding sleeves on the front and rear sides of the moving kit 301 slidably cooperated with the slide rod 202, and the driver 304 was connected to the external power supply normally, ensuring that the entire fixture was in the initial state of normal operation.

[0023] When installing and positioning marine sulfuric acid and mixed liquid storage tanks, operators first use hoisting equipment to slowly place the tank onto the rollers 203 of the clamping assembly 2 on one side. Because the rollers 203 are located at the four corners of the clamping assembly 2, and the smoothness of the rotating shaft is optimized, they can easily support the tank and significantly reduce movement resistance, eliminating the need for manual and laborious adjustment of the tank's initial position. Subsequently, the operator activates the control switch connected to the driver 304, which energizes the electromagnetic ball 302, causing it to generate magnetic force. At this time, pushing the moving kit 301 of the magnetic moving positioning assembly 3 causes the moving plate 303 to slide stably left and right along the elliptical slide rod 101 under the cooperation of the elliptical through hole 305 and the elliptical slide rod 101. Simultaneously, the sliding sleeve on the moving kit 301 slides synchronously along the slide rod 202. This dual-guide structure ensures that the moving plate 303 drives the electromagnetic ball 302 to accurately approach the outer wall of the tank. After the electromagnetic ball 302 magnetically attracts the storage tank, it continues to push the magnetic moving positioning component 3. Under the traction of the magnetic force, the storage tank moves along the roller 203 with the electromagnetic ball 302 to the other side of the clamping component 2 until both ends of the storage tank are completely inside the hollow area of ​​the clamping components 2 on both sides, achieving the initial positioning of the storage tank. Finally, the operator manually turns the locking part 204 on the rotating shaft of the roller 203 to lock the rotating shaft of the roller 203, preventing the roller 203 from rotating accidentally. At the same time, the electromagnetic ball 302 is kept energized. Through the synergistic effect of the magnetic force and the clamping component 2, the storage tank is firmly fixed on the tooling, completing the entire installation and positioning process.

[0024] When unloading the storage tank, there is no need to remove complex mechanical fasteners, making the operation simple and efficient. The operator first manually moves the locking component 204 to release it from the rotating shaft of the roller 203, allowing the roller 203 to rotate again. Next, the operator turns off the driver 304 via a control switch, cutting off the power to the electromagnetic ball 302. The electromagnetic ball 302 loses its magnetic force, releasing its attraction and fixation to the storage tank. At this point, the storage tank is only supported by the roller 203 within the clamping assembly 2. The operator only needs to apply slight force to push the tank, allowing it to slide smoothly along the roller 203 and move out of the hollow area of ​​the clamping assembly 2, quickly completing the unloading process. This effectively avoids the unloading difficulties caused by corrosion or jamming of fasteners in traditional mechanical fixtures, significantly reducing unloading time.
