Technical Field
[0001] This utility model relates to the field of tank transportation technology, and in particular to a shock-absorbing and fixing device for a liquid ammonia transport vehicle. Background Technology
[0002] Liquid ammonia, as an important chemical raw material, is widely used in fertilizer production, refrigeration, pharmaceuticals, and other fields. Due to its strong corrosiveness, volatility, and high-pressure hazard, the transportation and storage of liquid ammonia require extremely high safety standards. Liquid ammonia is usually stored in high-pressure tanks in liquid form and transported by specialized vehicles.
[0003] However, during transportation, vehicle bumps, sudden braking, or uneven road surfaces can cause violent shaking of the liquid ammonia inside the tank, potentially damaging the tank structure and leading to leaks or even explosions due to sudden pressure increases. Therefore, the design of the shock-absorbing and securing devices on liquid ammonia transport vehicles is crucial, directly affecting the safety and stability of transportation. Utility Model Content

[0006] Two sets of clamping assemblies, each set of clamping assemblies includes a first semicircular ring and a second semicircular ring, and the first semicircular ring and the second semicircular ring have a detachable connection structure; U-shaped frames are connected to both the first semicircular ring and the second semicircular ring; multiple reinforcing rods are detachably connected between the two U-shaped frames on the same side.
[0007] The shock absorption device includes a longitudinal buffer assembly and a transverse buffer assembly. The longitudinal buffer assembly includes a fixed base, a buffer seat located above the fixed base, and multiple first hydraulic shock absorbers installed between the fixed base and the buffer seat.

Detailed Implementation
[0021] Example 1
[0022] like Figures 1-3 As shown in the figure, the shock-absorbing and fixing device for a liquid ammonia transport vehicle proposed in this embodiment includes a shock-absorbing device and two sets of clamping components.
[0023] Both clamping assemblies include a first semicircular ring 101 and a second semicircular ring 102, with a detachable connection between the first semicircular ring 101 and the second semicircular ring 102. Rubber pads 4 are installed on the inner surfaces of both the first semicircular ring 101 and the second semicircular ring 102. The rubber pads 4 convert rigid clamping into flexible clamping, reducing the probability of damage to the tank surface. Both ends of the first semicircular ring 101 are connected to insert rods 13, and both ends of the second semicircular ring 102 are connected to sleeves 14 for inserting the ends of the insert rods 13. Each of the second semicircular rings 102 is connected to a U-shaped frame 2; a reinforcing frame 3 is connected between the first semicircular ring 101 and the U-shaped frame 2, and between the second semicircular ring 102 and the U-shaped frame 2; multiple reinforcing rods 10 are detachably connected between the two U-shaped frames 2 on the same side; a fixing block 17 is connected to the upper and lower parts of the outer end of the U-shaped frame 2, and the two ends of the reinforcing rod 10 are detachably connected to the fixing block 17 on the corresponding side. It should be noted that the reinforcing rod 10 and the fixing block 17 are connected by bolts and nuts. The above connection method is a common connection structure, so it will not be described in detail.
[0024] The shock absorption device includes a longitudinal buffer assembly and a lateral buffer assembly. The longitudinal buffer assembly includes a fixed base 5, a buffer seat 6 positioned above the fixed base 5, and multiple first hydraulic shock absorbers 71 installed between the fixed base 5 and the buffer seat 6. The fixed base 5 is fixedly mounted on the vehicle body. Multiple second guide rods 12 are connected to the fixed base 5, and the second guide rods 12 movably pass through the buffer seat 6. A second limiting block 121 is connected to the upper end of each second guide rod 12. Two sets of lateral buffer assemblies are provided, each set installed at one end of the buffer seat 6. Each set of lateral buffer assemblies includes a side plate 8 and two sliding plates 9. The system includes two second hydraulic shock absorbers 72, a side plate 8 fixed to a buffer seat 6, and two sliding plates 9 slidably mounted on the buffer seat 6. It should be noted that the sliding plates 9 are detachably connected to the corresponding U-shaped frame 2 via bolts and nuts, and the side plate 8 is connected to both sliding plates 9 via the second hydraulic shock absorbers 72. A first guide rod 11 is movably inserted through both ends of the side plate 8, connecting to the corresponding sliding plate 9. A first limiting block 111 is connected to the outer end of the first guide rod 11. The first guide rod 11 and the second guide rod 12 are used to limit the movement direction of the side plate 8 and the buffer seat 6, respectively.
[0025] The combination of two sets of clamping components, multiple reinforcing rods 10 and multiple U-shaped frames 2 in this technical solution forms a three-dimensional frame structure on the outside of the tank, which can prevent the tank from rolling during movement or transportation and improve the fixing effect of the tank.
[0026] With the cooperation of the fixed base 5, the buffer seat 6, and multiple first hydraulic shock absorbers 71, vertical shock absorption of the tank can be achieved. When the vehicle encounters bumps, potholes, or speed bumps during driving, the first hydraulic shock absorber 71 absorbs the vertical impact energy of the tank, preventing the tank from violently jumping up and down. The tank is not fixedly installed on the buffer seat 6; the tank moves with the sliding plate 9. With the cooperation of multiple second hydraulic shock absorbers 72, horizontal shock absorption of the tank can be achieved, thereby improving the shock absorption effect of the tank and enabling the tank to be transported stably.
[0027] Example 2
[0028] like Figure 3 As shown, the shock absorption and fixing device for a liquid ammonia transport vehicle proposed in this embodiment has the following features compared to Embodiment 1: In this embodiment, threaded rods 15 are movably provided through the upper and lower ends of the U-shaped frame 2 adjacent to the first semicircular ring 101. The threaded rods 15 also movably pass through the end of the first semicircular ring 101. A knob 16 is connected to the outer end of the threaded rods 15. Threaded grooves 1021 are provided at both ends of the second semicircular ring 102.
[0029] In this embodiment, the first semicircular ring 101 and the second semicircular ring 102 are closed together, and the threaded rod 15 is driven to rotate so that its end is threadedly connected to the threaded groove 1021, thereby completing the fixed connection between the first semicircular ring 101 and the second semicircular ring 102. By setting the above connection method, compared with the traditional method of climbing to the center of the top of the tank and connecting with bolts, the fixing process is more convenient.
[0030] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
