Abstract
Description
Technical Field
[0001] This utility model relates to the production of chemical products, and more specifically, to a safe and convenient liquid ammonia cylinder transfer vehicle. Background Technology
[0002] Liquid ammonia is a flammable and explosive gas with an auto-ignition point of 651°C and an explosive limit of 15.7% to 27.4%. When it reaches this concentration range in the air, it can ignite or explode upon contact with an open flame. It is toxic to humans, possessing strong irritant and corrosive properties. Low concentrations can irritate mucous membranes, while high concentrations can lead to tissue necrosis. Inhalation of high concentrations of ammonia can be fatal within a short time, primarily damaging the respiratory system, manifesting as symptoms such as tearing, coughing, and chest tightness; in severe cases, it can lead to pulmonary edema and respiratory failure. Liquid ammonia leaks rapidly, creating large contaminated and flammable / explosive zones.
[0003] Currently, most companies use forklifts or electric hoists when transferring liquid ammonia cylinders within their premises. However, forklifts and electric hoists pose significant safety risks when lifting liquid ammonia cylinders at high heights. Sudden braking or improperly secured cylinders can cause them to fall, resulting in damage and leakage. Diesel forklift exhaust can also produce sparks; if the flame arrester is not checked promptly and found to be faulty, a leaking liquid ammonia cylinder could easily cause an accident. Electric hoists also pose a risk of sparks from electrical components and hooks colliding with metal objects.

This utility model does not make specific limitations. Those skilled in the art can choose according to their needs, as long as the suspension rod 5 connected to the boom 61 can be raised and lowered.
[0033] The system comprises a trolley 3, a clamp 1, a clamping force structure, a suspension rod 5, and a lifting system 6. When the clamp 1 lifts the liquid ammonia cylinder 2, it utilizes the lever principle to achieve a clamping force several times the weight of the object through the clamping mechanism. The heavier the object being clamped, the stronger the clamping force, and it also possesses stable self-locking properties.
[0034] In one or more specific embodiments of this utility model, the lifting system 6 includes a boom 61, a hydraulic lifting cylinder 62, a pump 63, a main support for the boom 64, a lifting shaft, a pressure rod 65, and a pressure relief valve 66. The lifting shaft is installed on the main support for the boom 64, and each boom 61 is connected to the main support for the boom 64 through the lifting shaft. Each suspension rod 5 is connected to one boom 61.
[0035] In one or more specific embodiments of this utility model, the safe and convenient liquid ammonia cylinder transfer vehicle also includes the same number of connecting sleeves 7 as the clamps 1. Each connecting sleeve 7 is mounted on a suspension rod 5, and each connecting sleeve 7 is equipped with a connecting ring 71. Each connecting ring 71 is connected to a clamping force structure.
[0036] In one or more specific embodiments of this utility model, there are two clamps 1.
[0037] In one or more specific embodiments of this utility model, a clamp 1 includes a clamping part 11, a clamping shaft 12, and two clamping handles 13. A clamping force structure includes two clamping force chains 4, one end of which is connected to one clamping handle 13, and the other ends of both clamping force chains 4 are connected to a connecting ring 71. The clamping part 11, the clamping shaft 12, and the two clamping handles 13 form a scissor-like clamping method to clamp the liquid ammonia cylinder 2. The two clamping force chains 4, as the clamping force structure, form a lever principle with the clamp 1 to achieve a clamping force several times the weight of the object. The heavier the object being clamped, the stronger the clamping force, and it has stable self-locking properties.
[0038] In one or more specific embodiments of this utility model, the clamping force chain 4 and the clamp handle 13 are connected by a clamping ring, and each connecting sleeve 7 is fixed to the suspension rod 5 by two locking bolts.
[0039] In one or more specific embodiments of this utility model, the clamping part 11 is arc-shaped, which can better clamp the liquid ammonia cylinder 2.
[0040] In one or more specific embodiments of this utility model, in order to prevent the clamp 1 from damaging the liquid ammonia cylinder 2 itself during the lifting process and causing danger, a buffer rubber band 14 is provided inside the clamping part 11.
[0041] In one or more specific embodiments of this utility model, in order to further improve safety, a liquid ammonia cylinder protective ring 21 is provided on the liquid ammonia cylinder 2.

[0043] In one or more specific embodiments of this utility model, in order to further increase safety, a buffer rubber block 32 is provided at the front of the trolley 3 near the clamp 1.
[0044] In one or more specific embodiments of this utility model, the suspension rod 5 is provided with an adjustment positioning hole 51. The adjustment positioning hole 51 is used to adjust the position of the connecting sleeve 7 to adapt to different sizes of liquid ammonia cylinders 2, so as to avoid the clamp 1 colliding with the front of the trolley 3 or the gap between the clamp 1 and the buffer rubber block 32 being too large, which would cause large shaking and improve safety risks. Under normal circumstances, the connecting sleeve 7 is installed in a suitable position on the suspension rod 5 to adapt to the conventional standard size. When the size of the liquid ammonia cylinder 2 is larger than the conventional standard size, the connecting sleeve 7 moves away from the trolley 3.

[0047] In one or more specific embodiments of this utility model, the trolley 3 is also connected to a handrail 33 for convenient transportation.
[0048] In one or more specific embodiments of this utility model, in order to prevent sparks from being generated during metal collisions and causing danger, the clamp 1, clamping chain 4, and anti-sway chain 9 are preferably made of high-strength copper alloy.
[0049] During use, the operator first adjusts the connecting sleeve 7 according to the diameter of the liquid ammonia cylinder 2 so that the high-strength copper alloy clamp 1 can better clamp the liquid ammonia cylinder 2. After clamping, the anti-sway chain 9 is fixed to prevent the liquid ammonia cylinder 2 from swaying during the lifting process. The operator then uses the manual operation lever 65 to start the manual pump to supply oil to the hydraulic lifting cylinder 62 and lift the liquid ammonia cylinder 2. The lifted liquid ammonia cylinder 2 is about 0.1 meters off the ground to prevent it from falling and causing damage to the liquid ammonia cylinder 2 in case of an accident. The operator holds the handrail 33 and pushes the liquid ammonia cylinder 2 to the usage location. Then, the operator presses the manual pressure relief valve 66 to place the liquid ammonia cylinder 2 in the usage position.
[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
