Technical Field
[0001] This utility model relates to the field of structural design technology, specifically to a lifting ring and a charging pile. Background Technology
[0002] With global emphasis on sustainable energy and reducing greenhouse gas emissions, electric vehicles, as a clean energy mode of transportation, are experiencing rapid market acceptance and adoption. This has not only driven advancements in electric vehicle technology but also spurred a surge in demand for related infrastructure, particularly charging stations. As a crucial facility for replenishing electric vehicle energy, the rapid and widespread deployment of charging stations is essential for the widespread adoption of electric vehicles. Therefore, charging station installation technology has become a vital segment of the new energy vehicle market, significantly impacting installation efficiency, cost reduction, and construction safety. Currently, with the continuous advancement of charging station technology, their power and size are constantly increasing, placing higher demands on the safety and flexibility of hoisting installation. To adapt to the installation needs of different sites and environments, charging station installation methods are becoming increasingly diversified, with hoisting becoming a common method due to its flexibility and efficiency.
[0003] Currently, the lifting ring structures commonly used in the hoisting of charging piles have several key problems. First, these lifting rings have a fixed angle when locked, making it impossible to adjust them according to the actual hoisting angle. This results in the force direction of the lifting ring being inconsistent with the direction of the hoisting rope, increasing the risk of the lifting ring loosening during hoisting and potentially causing safety accidents. Second, existing lifting ring structures typically lack sealing performance after being locked to the product, requiring additional sealing measures such as applying sealant. This not only increases construction difficulty but also reduces the reliability of the seal, affecting the stability and durability of the charging pile in various environments. In conventional lifting ring structures, the lifting lug and bolt are usually designed as a single unit. Once the lifting lug is fastened to the base via threads at the bottom, its direction cannot be changed. During hoisting, the threads at the bottom of the lifting lug are subjected to axial rotational force, causing the lug to loosen and affecting the hoisting and installation. Furthermore, this integrated design limits the flexibility and adjustability of the lifting lug, making it difficult to adapt to different hoisting angles and directions in complex construction sites, increasing the difficulty of the operation.
[0004] Therefore, to solve the above problems, a new type of lifting ring structure needs to be developed. This structure should be adaptable to varying lifting angles, ensuring that the lifting lugs and ropes are aligned in force direction during charging pile installation to prevent loosening, and possess excellent sealing performance to adapt to various environmental conditions. This novel lifting ring structure aims to provide a safer and more efficient solution for the installation of electric vehicle charging piles through technological innovation. Utility Model Content
[0005] The purpose of this utility model is to provide a lifting ring and a charging pile to overcome the shortcomings of the existing lifting ring structure, which has a high risk of the charging pile coming loose during the lifting process due to the fixed angle and inconsistent force.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A hanging ring, comprising:
[0008] The lifting lugs have an upper part for fixing the connecting parts during lifting, and a lower part for rotating connection with the lifting lug bolts;
[0009] The upper part of the eye bolt is rotatably connected to the eye lug, and the lower part is fixedly connected to the eye base;
[0010] The upper part of the lifting ring base is fixedly connected to the lifting ring bolts, and the lower part is connected to the charging pile during hoisting.
[0011] The lower part of the lifting lug has a socket hole, and the upper part of the lifting bolt is sleeved with the lower part of the lifting lug through the socket hole.
[0012] A limiting part is provided at the bottom of the socket, and the lifting eye bolt restricts the vertical movement of the lifting eye lug through the limiting part.
[0013] The lifting lugs also have circlip grooves, in which C-shaped circlips are installed.
[0014] The eye bolt is fitted with a sealing ring.
[0015] A fixing hole is opened on the top of the lifting eye base, and a thread is tapped in the fixing hole. The lifting eye bolt is connected to the lifting eye base through the thread.
[0016] The lifting ring base is connected to the charging pile by fastening screws or by welding.
[0017] A charging pile is based on a lifting ring. The charging pile includes a charging pile body and several lifting rings, which are installed on a part of the charging pile that is easy to lift.
[0018] Compared with the prior art, the present invention has the following beneficial technical effects:
[0019] This utility model provides a lifting ring with a 360° rotatable connection between the lifting ring lug and the lifting ring bolt. This allows the ring to automatically adapt to the direction of the lifting rope during hoisting, reducing the risk of loosening and enhancing stability and safety. A limiting part at the bottom of the socket restricts the vertical displacement of the lifting ring lug, further strengthening overall stability. The sealing ring on the lifting ring bolt forms a seal during connection, preventing foreign object intrusion and improving sealing performance. Furthermore, the C-shaped retaining spring on the lifting ring lug ensures axial positioning, preventing dislodgement and guaranteeing structural integrity and system reliability. This allows the lifting ring to operate reliably under complex working conditions, effectively extending its service life.
[0020] This utility model provides a charging pile that, by installing a lifting ring at a convenient location, allows the charging pile to adapt to different lifting angles during installation. This eliminates the need for complex adjustments, enabling quick and accurate installation, improving installation efficiency, and reducing construction difficulty and time costs. The lifting ring's excellent sealing performance effectively prevents external substances from entering the charging pile, protecting electrical components and ensuring their long-term stable operation in harsh environments, reducing malfunctions and maintenance, and lowering operating costs.

[0030] Example 1:
[0031] This utility model provides a specific application scenario where the lifting ring is installed on a charging pile using a beam-mounted type, such as... Figures 1 to 2 As shown, the lifting ring includes:
[0032] The lifting lug 2 has an upper part for fixing the connecting parts during hoisting, and a lower part with a socket hole. The bottom of the socket hole has a limit part and a circlip groove. A C-type circlip 1 is installed in the circlip groove to limit the vertical movement of the lifting lug 2 and prevent it from falling out.
[0033] The upper part of the eye bolt 3 is sleeved with the lower part of the eye lug 2 through the sleeve hole, so that the eye lug 2 can rotate relative to it, achieving 360° rotation. The eye bolt 3 is equipped with a sealing ring for sealing, and its lower part is fixedly connected to the eye base 6.
[0034] The lifting lug 2 and the lifting bolt 3 are connected by a rotating mechanism, allowing for 360° free rotation. During lifting operations, regardless of changes in the direction of the lifting rope, the lifting lug 2 can quickly adjust its angle to ensure that it remains aligned with the direction of force on the lifting rope. This dynamic adjustment capability effectively disperses stress during the lifting process, greatly reducing the risk of the lifting lug becoming loose and ensuring the safety and stability of the lifting process. It is particularly suitable for the lifting and installation of heavy equipment such as charging piles.
[0035] The limiting part at the bottom of the lower sleeve hole of the lifting lug 2 works in conjunction with the lifting bolt 3 to precisely limit the vertical displacement of the lifting lug 2. This design prevents the lifting lug 2 from moving up and down due to gravity or external impact when bearing lifting loads, further enhancing the overall stability of the lifting ring structure and ensuring that the lifting ring always maintains a reliable working state in complex lifting environments.
[0036] A C-type retaining circlip is installed in the retaining circlip groove on the lifting lug 2, providing reliable axial positioning for the lifting lug 2. When the lifting ring is subjected to lifting force, vibration, or other external forces, the C-type retaining circlip can tightly lock the lifting lug 2, preventing it from accidentally coming off the lifting bolt 3. This design ensures the integrity of the lifting ring structure, avoids safety accidents caused by the lifting lug 2 coming off, improves the safety and reliability of the entire lifting ring system, and ensures the continuity and stability of equipment lifting operations.
[0037] The upper part of the lifting eye base 6 is connected to the lifting eye bolt 3 by threads. The upper part of the lifting eye base 6 has a fixing hole with threads tapped inside. The lower part is connected to the charging pile by fastening screws 8 during hoisting. During installation, it is first installed on the mounting beam 7 by fastening screws 8.
[0038] When the sealing ring mounted on the eye bolt 3 is tightened to the eye base 6, it is compressed and fills the tiny gaps in the connection area, forming a tight seal. This effectively prevents dust, moisture, and other foreign matter from entering through the connection between the eye bolt 3 and the eye base 6, protecting the internal structure of the eye from corrosion and damage, ensuring a stable internal environment, extending the service life of the eye, and enabling it to adapt to various complex working conditions.
[0039] The sealing gasket 5 is placed on the upper part of the lifting ring base 6 and cooperates with the cabinet skin 4. After installation, it achieves a seal by compressing the lifting ring base 6 and the cabinet skin 4, ensuring the seal between the lifting ring base 6 and the cabinet body.
[0040] When installing the lifting ring, first install the lifting ring base 6 onto the mounting beam 7 using fastening screws 8, providing an installation foundation for the entire lifting ring structure.
[0041] Next, place the sealing gasket 5 on the upper part of the lifting ring base 6, ready to cooperate with the cabinet skin 4 to achieve a seal.
[0042] Then, place the cabinet skin 4 on top of the lifting ring base 6, so that it is in close contact with the sealing gasket 5.
[0043] Next, place the lifting ring lug 2 on the upper part of the cabinet skin 4, ensuring that the lifting ring base 6, cabinet skin 4, and lifting ring lug 2 are basically concentric. At this time, the lifting ring lug 2 can rotate 360° through the sleeve structure of the lower part with the lifting ring bolt 3, ensuring that the lifting ring lug 2 and the lifting rope are in the same direction of force at any lifting angle, preventing loosening.
[0044] Next, the eye bolt 3 is passed through the opening in the middle of the eye lug 2 and fastened to the eye base 6 by threads. During the fastening process, the sealing ring on the eye bolt 3 is compressed, which achieves the sealing between the mounting hole of the eye base 6 and the outside. At the same time, the sleeve structure between the upper part of the eye bolt 3 and the eye lug 2 ensures that the eye lug 2 can rotate flexibly.
[0045] Finally, use snap ring pliers to install the C-type snap ring 1 into the snap ring groove of the lifting lug 2 to further secure the lifting lug 2 and prevent it from coming off during use.
[0046] Example 2:
[0047] This utility model provides a specific application scenario where the lifting ring is installed on a charging pile using a beam-loaded installation method, such as... Figures 2 to 3 As shown, the lifting ring includes:
[0048] The lifting lug 2 has the same structure as in embodiment 1. The upper part is used for fixing the connecting parts, and the lower part is sleeved with the lifting bolt 3 through the sleeve hole, which can achieve 360° rotation. It has a retaining spring groove and installs a C-type retaining spring 1, which restricts the movement in the vertical direction through the bottom limiting part of the sleeve hole.
[0049] The upper part of the eye bolt 3 is rotatably connected to the eye lug 2 and equipped with a sealing ring, while the lower part is fixedly connected to the eye base 6 to ensure sealing and the rotation function of the eye lug 2.
[0050] The upper part of the lifting ring base 6 is threadedly connected to the lifting ring bolt 3. In this embodiment, the lifting ring base 6 is connected to the charging pile by welding. It is welded between the cabinet skin 4 and the mounting beam 7. The welding process achieves sealing and is tightly connected to the cabinet skin 4 and the mounting beam 7, providing a stable foundation for the lifting ring structure.
[0051] When installing the lifting ring, first pass the lifting ring base 6 through the mounting holes on the cabinet skin 4 and the mounting beam 7, and then fix the lifting ring base 6 to the cabinet by welding. The welding operation creates a seal between the lifting ring base 6 and the cabinet skin 4 and the mounting beam 7, ensuring the overall airtightness of the charging pile and effectively preventing foreign objects from entering.
[0052] Place the lifting lug 2 on the upper part of the lifting base 6, ensuring that the lifting base 6 and the lifting lug 2 are basically concentric, so that the lifting lug 2 can rotate freely on the concentric axis, ensuring that it is consistent with the direction of force on the lifting rope at any lifting angle.
[0053] The eye bolt 3 is passed through the opening in the middle of the eye lug 2 and fastened to the eye base 6 by threads. During the tightening, the sealing ring on the eye bolt 3 is compressed, which achieves the sealing between the mounting hole of the eye base 6 and the outside world, while ensuring that the eye lug 2 can rotate relative to the eye bolt 3.
[0054] Finally, use snap ring pliers to install the C-type snap ring 1 into the snap ring groove of the lifting lug 2 to prevent the lifting lug 2 from coming out and to maintain the stability of the entire lifting ring structure.
