Description

Technical Field

[0001] This utility model relates to the field of fixing liquid ammonia storage tanks, specifically a fixing structure for liquid ammonia storage tanks. Background Technology

[0002] In many industries, including chemical engineering, liquid ammonia is a commonly used industrial raw material, and the safety and stability of its storage are of paramount importance. Liquid ammonia storage tanks typically require suitable fixed structures to prevent dangerous situations such as displacement or tipping during use, storage, and transportation.

[0003] Traditional methods for securing liquid ammonia storage tanks often employ a combination of bolts and clamps. During installation, the clamps must first be fixed in their designated positions, and then the liquid ammonia tank is securely connected to the clamps using bolts. While this method provides some stability, it presents several inconveniences. First, the installation process is cumbersome, requiring precise alignment of the bolt holes and tightening of the bolts, consuming significant manpower and time. Second, in scenarios where liquid ammonia storage tanks need frequent placement or replacement, the bolt disassembly and installation operations must be repeated each time, greatly reducing work efficiency. Therefore, we propose a new securing structure for liquid ammonia storage tanks. Utility Model Content

[0022] 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.

[0023] Please see Figure 1-4 A fixing structure for liquid ammonia storage tanks includes a base 3, with a bearing assembly fixedly installed on the top of the base 3. The bearing assembly includes two crossbars 1 and multiple sets of arc-shaped connecting plates 2. The two crossbars 1 are connected by the multiple sets of arc-shaped connecting plates 2. Each of the two crossbars 1 on opposite sides is hinged with a pressing fixing structure. When fixing the liquid ammonia storage tank, the liquid ammonia storage tank is placed on the bearing assembly, and the side of the liquid ammonia storage tank is in contact with the arc-shaped connecting plates 2. At this time, the liquid ammonia storage tank will press down onto the pressing fixing structure. The upper end of the pressing fixing structure moves towards the side closer to the center point. At this time, the upper end of the pressing fixing structure presses against the upper surface of the liquid ammonia storage tank, thus completing the fixing of the liquid ammonia storage tank. This device uses the gravity of the liquid ammonia storage tank itself to achieve fixing. Compared with the existing structure that uses bolts and clips for fixing, it is easier to place the liquid ammonia storage tank and eliminates the process of installing clips and bolts.

[0024] Furthermore, the pressing and fixing structure includes an L-shaped rod 4, a vertical rod 5, and a top pressing block 6. The vertical rod 5 is hinged to the side of the horizontal rod 1. The lower end of the vertical rod 5 is fixedly installed with an L-shaped rod 4, and the upper end of the vertical rod 5 is fixedly installed with a top pressing block 6. When the liquid ammonia storage tank is placed, the side of the liquid ammonia storage tank located below will press against the L-shaped rod 4. At this time, the L-shaped rod 4 will slide to the opposite side. Then, the vertical rod 5 and the top pressing block 6 will move towards the side closer to the center point. Then, the top pressing block 6 will adhere to the surface of the liquid ammonia storage tank located above, thereby fixing the liquid ammonia storage tank.

[0025] Furthermore, the top pressing block 6 is provided with a rectangular groove 7 for fitting one side of the liquid ammonia storage tank. Multiple sets of springs 8 are installed equidistantly inside the rectangular groove 7. A T-shaped block 9 is fixedly installed at the end of the spring 8. The cross-section of the T-shaped block 9 is T-shaped.

[0026] Furthermore, a rubber block 10 is fixedly installed on one side of the T-shaped block 9 to fit the liquid ammonia storage tank. When the rubber block 10 fits into the liquid ammonia storage tank, the addition of a spring 8 can prevent the side of the liquid ammonia storage tank located below from pressing against the L-shaped rod 4 too quickly, causing the top pressing block 6 to move downwards instantly and smash into the surface of the liquid ammonia storage tank, resulting in a dent. The addition of the rubber block 10 and the spring 8 can reduce damage to the surface of the liquid ammonia storage tank.

[0027] Furthermore, the base 3 includes a vertical rod 11 fixedly installed at the bottom of the horizontal rod 1, a plug-in block 12, and a second spring 13. The plug-in block 12 has a hollow internal structure, and the second spring 13 is fixedly installed inside the plug-in block 12. The lower end of the vertical rod 11 is inserted into the plug-in block 12, and the second spring 13 is fixedly connected to the vertical rod 11. A roller 14 is fixedly installed at the lower end of the second spring 13. After the liquid ammonia storage tank is fixed, the device can be pushed directly when it needs to be transported. When passing over uneven ground, the second spring 13 can increase the shock absorption effect.

[0028] Furthermore, two adjacent plug-in blocks 12 are fixedly connected together by a connecting rod 15.

[0029] Structural Description:

[0030] Crossbar 1: Located in the load-bearing assembly, there are two of them arranged in parallel. Its main function is to connect with the arc-shaped connecting plate 2 to form the frame structure of the liquid ammonia storage tank, providing a lateral support foundation for the liquid ammonia storage tank. It also serves as the carrier of the hinged pressing and fixing structure, allowing the pressing and fixing structure to rotate around the crossbar 1 as an axis, thereby achieving the fixing action of the liquid ammonia storage tank.

[0031] Arc-shaped connecting plate 2: Multiple sets of arc-shaped connecting plates 2 are connected between two crossbars 1, and their arc-shaped design is adapted to the side shape of the liquid ammonia storage tank.

[0032] Base 3: This serves as the bottom support for the entire fixed structure. It includes components such as a vertical rod 11, a connecting block 12, and a second spring 13. The vertical rod 11 is fixed to the bottom of the horizontal rod 1, and its lower end is inserted into the hollow connecting block 12 and fixedly connected to the second spring 13. A roller 14 is installed at the lower end of the second spring 13. Base 3 provides stable support for the load-bearing components. Furthermore, during transportation, the expansion and contraction characteristics of the second spring 13 act as a shock absorber when traversing uneven ground, reducing damage to the liquid ammonia storage tank and the entire fixed structure caused by bumps or instability. Adjacent connecting blocks 12 are fixedly connected by a connecting rod 15, further enhancing the overall integrity and stability of the base.

[0033] L-shaped rod 4: As part of the pressing and fixing structure, its lower end is fixed to the vertical rod 5 and is L-shaped. When the liquid ammonia storage tank is placed on the bearing assembly, the side of the liquid ammonia storage tank located below will squeeze the L-shaped rod 4, causing it to slide to the opposite side, thereby driving the vertical rod 5 and the top pressing block 6 connected to it to move. It is one of the key components to realize the gravity-triggered fixing mechanism of the liquid ammonia storage tank.

[0034] Vertical rod 5: Vertical rod 5 is hinged to the side of horizontal rod 1, with its lower end connected to L-shaped rod 4 and its upper end fixed to top pressing block 6. It serves as a connection and transmission mechanism, transferring the squeezing force from the liquid ammonia storage tank onto the L-shaped rod 4 to the top pressing block 6, allowing the top pressing block 6 to move towards the center point under the weight of the liquid ammonia storage tank, thereby securing the liquid ammonia storage tank.

[0035] Top pressing block 6: Located at the upper end of the vertical rod 5, it is used to adhere to the upper surface of the liquid ammonia storage tank. A rectangular groove 7 is provided on one side, inside which multiple sets of springs 8, T-shaped blocks 9, and rubber blocks 10 are installed. When the top pressing block 6 is moved downwards by the vertical rod 5 to adhere to the liquid ammonia storage tank, it contacts the liquid ammonia storage tank through the rubber blocks 10, increasing friction and providing cushioning. Simultaneously, the springs 8 prevent the top pressing block 6 from instantly slamming into the surface of the liquid ammonia storage tank and causing dents due to excessive pressure on the L-shaped rod 4 during placement of the liquid ammonia storage tank, thus protecting the surface of the liquid ammonia storage tank.

[0036] Rectangular groove 7: It is opened on one side of the top pressing block 6 to fit the liquid ammonia storage tank, providing installation space for components such as spring 8 and T-shaped block 9, so that these components can be arranged in an orderly manner and work together to achieve the buffer protection function of the liquid ammonia storage tank surface.

[0037] Spring 8: Equivalently installed inside the rectangular groove 7, with one end fixed to the inner wall of the rectangular groove 7 and the other end fixed to the T-shaped block 9. When the top pressing block 6 has a rapid downward tendency, spring 8 will be compressed, absorbing some energy and slowing down the impact speed of the T-shaped block 9 and rubber block 10 on the surface of the liquid ammonia storage tank, thereby reducing damage to the liquid ammonia storage tank.

[0038] T-shaped block 9: With a T-shaped cross-section, it is installed at the end of spring-8. Its functions are twofold: first, to keep the rubber block 10 in a suitable position and in contact with the liquid ammonia storage tank under the support of spring-8; second, through its T-shaped structure, it can move stably within the rectangular groove 7, preventing it from shifting or coming off during the extension and contraction of spring-8, thus ensuring the reliability of the buffer protection mechanism.

[0039] Rubber block 10: Fixedly installed on one side of the T-shaped block 9 to fit against the liquid ammonia storage tank. Its material has a certain degree of softness and friction. When in contact with the liquid ammonia storage tank, it can increase the friction with the surface of the liquid ammonia storage tank, making the liquid ammonia storage tank more stable after being fixed and less prone to displacement. It can also play a buffering role when in contact with the liquid ammonia storage tank, avoiding damage to the surface of the liquid ammonia storage tank due to rigid contact.

[0040] Vertical rod 11: It is part of the base 3. Its upper end is fixed to the bottom of the horizontal rod 1, and its lower end is inserted into the plug block 12 and connected to the spring 13. Its main function is to connect the load-bearing components with the shock-absorbing part of the base 3, transmit weight and force, and make the whole structure an organic whole, ensuring the stability and reliability of the structure under various working conditions.

[0041] Connector block 12: It has a hollow internal structure to accommodate the vertical rod 11 and spring 13. It provides a mounting position for spring 13 and, through its cooperation with the vertical rod 11, enables spring 13 to play a shock-absorbing role when the vertical rod 11 moves up and down relative to it. It also provides a supporting frame for the structural stability of the entire base 3.

[0042] Spring 2 13: Installed inside the plug-in block 12, its upper end is fixedly connected to the vertical rod 11, and its lower end is connected to the roller 14. During transportation, when the ground is uneven and the entire device shakes up and down, spring 2 13 will extend and retract according to the amplitude of the shaking, absorbing and releasing energy, thereby reducing the impact of the shaking on the liquid ammonia storage tank and the entire fixed structure, protecting the integrity of the liquid ammonia storage tank and the structure, and also improving the stability and comfort during transportation.

[0043] Roller 14: Installed at the lower end of spring 2 13, when it is necessary to move the device with the liquid ammonia storage tank, the roller 14 contacts the ground, so that the device can roll on the ground easily, reducing the friction when pushing, and facilitating the movement and transportation of the device.

[0044] Connecting rod 15: Connects two adjacent plug-in blocks 12, enhancing the connection strength and overall integrity between the plug-in blocks 12 in the base 3. This allows multiple plug-in blocks 12 to work collaboratively, evenly distributing the weight of the entire device and the various forces exerted during transportation, further improving the stability and reliability of the base 3 and ensuring the safety performance of the entire fixed structure under complex working conditions.

[0045] Working principle: When the liquid ammonia storage tank is placed, the side of the liquid ammonia storage tank located below will press against the L-shaped rod 4. At this time, the L-shaped rod 4 will slide to the opposite side. Then, the vertical rod 5 and the top pressing block 6 will move to the side closer to the center point. Then, the top pressing block 6 will fit against the surface of the liquid ammonia storage tank located above, thereby fixing the liquid ammonia storage tank.
