Description

Technical Field

[0001] This utility model belongs to the field of hydrogen storage cylinder hoisting technology, specifically relating to a hoisting sling for vertical hoisting of large-capacity hydrogen storage cylinders. Background Technology

[0002] With the global emphasis on clean and renewable energy, the hydrogen energy industry has become one of the fastest-growing sectors in the energy field in terms of investment. Hydrogen energy is considered a crucial component of future national energy systems, boasting abundant resources, a green and low-carbon profile, and wide applicability, and is hailed as the most promising secondary energy source of the 21st century.

[0003] Hydrogen is being used more and more widely as a clean energy source. Safety is paramount during the storage and transportation of hydrogen. The method of hoisting hydrogen cylinders directly affects their safety and stability, especially when hoisting them vertically; choosing the right lifting slings is crucial.

[0004] The vertical hoisting of hydrogen storage cylinders requires ensuring the stability and safety of the cylinders during the hoisting process. When designing such slings, the primary considerations are their load-bearing capacity and tensile strength. The weight of the cylinder and the pressure of the gas necessitate that the slings possess sufficient strength to prevent accidents during hoisting. Furthermore, the sling design must also take into account the shape and dimensions of the cylinder to ensure a perfect fit and prevent slippage or tilting.

[0005] To address these issues, several attempts have been made, such as using lifting devices with rubber bearings and chain connections, and designing storage devices specifically for storing and transporting hydrogen cylinders in bulk. While these methods have improved aspects to some extent, they still have limitations, such as the need to improve stability and safety when lifting large-capacity hydrogen cylinders.

[0006] Specifically, a search revealed a hydrogen storage cylinder hoisting device for fuel cell vehicle production, with publication number CN207738306U and publication date of August 17, 2018. This design employs rubber bearings and chain connections, which provides some cushioning and protects the cylinders. However, its structural design is primarily suited for smaller cylinders, resulting in insufficient stability for hoisting large-capacity hydrogen storage cylinders and a tendency for lateral slippage during hoisting. Therefore, this design cannot meet the high stability and safety requirements for vertical hoisting of large-capacity hydrogen storage cylinders.

[0007] A search revealed a hydrogen storage cylinder storage device with publication number CN221024793U, published on May 28, 2024. This product employs a stackable configuration, which maximizes space utilization, increases storage capacity, and reduces floor space. However, because it primarily focuses on space efficiency during storage and transportation, it doesn't adequately consider the ease of operation and safety during hoisting. Therefore, this design struggles to provide an effective solution for the vertical hoisting requirements of large-capacity hydrogen storage cylinders.

[0008] The aforementioned problems indicate that current hydrogen cylinder hoisting devices on the market are insufficient to effectively meet the new requirements for stability and safety when vertically hoisting large-capacity hydrogen cylinders. Therefore, this invention provides a sling for vertically hoisting large-capacity hydrogen cylinders to overcome these shortcomings and offer a more intelligent, efficient, and adaptable solution for changing environments. Utility Model Content

[0009] A lifting sling for vertically hoisting large-capacity hydrogen storage cylinders includes a main sling, a secondary sling, a positioning port, a buffer pad, and an adjustment device. The main sling has a ring-shaped structure, and its width and thickness are customized according to the cylinder specifications to ensure sufficient load-bearing capacity. The secondary sling is a circumferential fixing sling fixed to the inside of the main sling to secure the cylinder body and prevent it from falling off during hoisting. The positioning port is located at the bottom of the main sling to fix the cylinder mouth and provide a fixed limit. The buffer pad is located at the contact point between the main sling and the cylinder to effectively reduce friction damage to the cylinder surface and increase stability. The adjustment device is located at both ends of the main sling to adjust the length of the sling and ensure secure hoisting.

[0010] Furthermore, the inner side of the main belt is provided with several anti-slip protrusions, which are semi-circular and evenly distributed on the inner side of the main belt to increase the friction with the surface of the gas cylinder and further improve safety.

[0011] Furthermore, each end of the secondary belt is provided with a connecting buckle, which is connected to the fixing hole on the main belt by a pin to ensure that the connection between the secondary belt and the main belt is firm and reliable.

[0012] Furthermore, the positioning port is equipped with an elastic pad made of highly elastic rubber material, which can adapt to gas cylinder mouths of different diameters and ensure their stability during hoisting.

[0013] Furthermore, the surface of the buffer pad is provided with anti-slip texture, which consists of several staggered protrusions, further increasing the friction with the surface of the gas cylinder and preventing the gas cylinder from sliding during hoisting.

[0014] Furthermore, the adjustment device includes an adjustment buckle and an adjustment strap. The adjustment buckle is fixed to one end of the main strap, and the adjustment strap passes through the adjustment buckle and is fixed to the other end of the main strap. By adjusting the adjustment buckle, the length of the sling can be easily adjusted to ensure the tightness during hoisting.

[0015] Furthermore, the outer side of the main belt is provided with an anti-wear layer, which is made of high-strength wear-resistant material, and can effectively protect the main belt from wear during the hoisting process and extend its service life.

[0016] Furthermore, the main belt is provided with reinforcing ribs at both ends. The reinforcing ribs are made of high-strength fiber material and are embedded inside the main belt to enhance the tensile strength of the main belt and ensure its stability when hoisting large-capacity hydrogen storage cylinders.

[0017] Furthermore, the inner side of the auxiliary belt is provided with an anti-slip coating, which is made of a material with a high coefficient of friction, and can further increase the friction with the surface of the gas cylinder to prevent the gas cylinder from sliding during hoisting.

[0018] Furthermore, the bottom of the positioning port is provided with a guide groove, which is V-shaped and used to guide the gas cylinder mouth into the positioning port to ensure accurate positioning during the hoisting process.

[0019] The structure and operating principle of this invention are as follows: When hoisting a large-capacity hydrogen storage cylinder, the main strap is first wrapped around the cylinder, and its length is adjusted using an adjusting device to ensure a tight fit with the cylinder. Then, the auxiliary strap is fixed to the cylinder body, and the connection between the auxiliary strap and the main strap is ensured to be secure and reliable through connecting buckles and fixing holes. Next, the positioning port is fitted onto the cylinder opening, and the elastic padding ensures the stability of the cylinder opening during hoisting. Finally, the lifting rings of the straps are connected to the hook or hoisting equipment, ensuring a secure connection. During hoisting, the main strap and auxiliary strap work together to ensure the stability and safety of the cylinder. The anti-slip protrusions and anti-slip texture of the buffer pad on the inner side of the main strap increase the friction with the cylinder surface, preventing the cylinder from sliding during hoisting. The anti-slip coating on the inner side of the auxiliary strap further increases the friction with the cylinder surface, ensuring the stability of the cylinder during hoisting. The elastic pads and guide grooves at the positioning port ensure accurate positioning of the gas cylinder opening during hoisting, preventing the cylinder from tilting or sliding. The adjusting buckles and straps of the adjustment device allow for easy adjustment of the sling length, ensuring secure hoisting. The abrasion-resistant layer on the outer side of the main sling protects it from wear during hoisting, extending its service life. Reinforcing ribs at both ends of the main sling enhance its tensile strength, ensuring stability when hoisting large-capacity hydrogen storage cylinders.

[0020] The beneficial effects of this utility model are:

[0021] 1. The anti-slip protrusions on the inner side of the main belt and the anti-slip texture of the buffer pad increase the friction with the surface of the gas cylinder, effectively preventing the gas cylinder from sliding during hoisting and improving the safety of hoisting.

[0022] 2. The anti-slip coating on the inner side of the auxiliary belt further increases the friction with the surface of the gas cylinder, ensuring the stability of the gas cylinder during hoisting and preventing the gas cylinder from sliding during hoisting.

[0023] 3. The elastic pads and guide grooves of the positioning port ensure accurate positioning of the gas cylinder opening during hoisting, preventing the gas cylinder from tilting or sliding during hoisting and improving the stability of hoisting. Attached Figure Description
