Description

Technical Field

[0001] This utility model belongs to the field of lifting ring technology, and relates to a cabinet lifting ring structure and a charging pile. Background Technology

[0002] The size and weight of charging piles vary depending on the model; some high-power charging piles or those with large-capacity battery storage modules can weigh hundreds of kilograms. Traditional manual handling methods are inefficient and pose safety risks when installing these charging piles. Lifting rings provide connection points for lifting equipment such as cranes, hoists, or manual hoists, allowing charging piles to be easily and safely lifted to designated installation locations, such as next to parking lot pillars or on building exteriors.

[0003] During transportation from the manufacturer to the usage site, charging piles may encounter bumpy roads and multiple loading and unloading processes. Lifting rings can secure the charging piles to the transport vehicle, preventing them from sliding or colliding within the cargo compartment. Passing ropes or fastening straps through the lifting rings and securing them to fixed points within the cargo compartment effectively reduces damage to the delicate electronic components inside the charging pile caused by vibration and impact during transport.

[0004] Existing rack lifting ring structure such as Figure 1 He Ru Figure 2 As shown, the system includes a ceiling ring 01, an outer reinforcing rib 02, a top plate 03, an inner reinforcing rib 04, and a lifting ring bolt 05. The lifting ring bolt 05 passes through the inner reinforcing rib 04, the top plate 03, and the outer reinforcing rib 02 and is threadedly connected to the ceiling ring 01. The lifting ring bolt 05 is fully welded to the inner reinforcing rib 04, the top plate 03, and the outer reinforcing rib 02. However, the existing cabinet lifting rings have the following problems:

[0005] 1) Full welding has low welding efficiency and is prone to breakage and missing welds; 2) Full welding is difficult to inspect; 3) Full welding does not meet the requirements and the top of the cabinet is prone to water leakage. Utility Model Content

[0006] The purpose of this utility model is to provide a cabinet lifting ring structure and a charging pile. By optimizing the cabinet lifting ring structure, the connecting parts and the outer reinforcing ribs of the cabinet are spot welded, and the outer reinforcing ribs of the cabinet are welded to the top plate of the cabinet. This shortens the inspection time, improves the welding efficiency, and solves the technical problems of existing cabinet lifting ring structures that use full welding to fix and connect the parts. Full welding has low processing efficiency, is prone to broken welds, missing welds, high inspection difficulty, and the top of the cabinet is prone to water leakage if the weld does not meet the requirements.

[0007] To solve the above technical problems, the present invention adopts the following technical solution: a cabinet lifting ring structure includes: a lifting ring, an outer reinforcing rib of the cabinet, a top plate of the cabinet, and a connector; the top plate of the cabinet is set at the upper end of the charging pile cabinet, the outer reinforcing rib of the cabinet is set on the side of the top plate of the cabinet away from the charging pile and is fixedly connected to the top plate of the cabinet, the lifting ring passes through the outer reinforcing rib of the cabinet from top to bottom and is fixedly connected to the connector, and the connector is set inside the outer reinforcing rib of the cabinet.

[0008] Furthermore, the lifting ring includes a ring-shaped component and a fastener. The fastener is fixedly installed on one side of the ring-shaped component and passes through the outer reinforcing rib of the cabinet to be fixedly connected to the connector.

[0009] Furthermore, the outer reinforcing rib of the cabinet is shaped like a "Z", with a first through hole on the upper end face and the lower end face fixedly connected to the top plate of the cabinet.

[0010] Furthermore, the lower end face of the outer reinforcing rib of the cabinet is welded to the top plate of the cabinet.

[0011] Furthermore, the upper end face of the connector is spot-welded to the outer reinforcing rib of the cabinet.

[0012] Furthermore, the connection between the annular component and the fastener is smooth and burr-free.

[0013] Furthermore, the ring-shaped member and the fastener can be an integral structure.

[0014] Furthermore, the connector is a welded nut.

[0015] Furthermore, the lifting ring passes through the outer reinforcing rib of the cabinet from top to bottom and is threadedly connected to the connector.

[0016] A charging pile includes a charging pile cabinet and the aforementioned cabinet lifting ring structure, wherein the cabinet lifting ring structure is located on the top of the charging pile cabinet.

[0017] Compared with the prior art, the present invention has the following beneficial technical effects:

[0018] This utility model discloses a cabinet lifting ring structure. The external reinforcing ribs of the cabinet can reduce the risk of water leakage caused by welding gaps. During the process of water flowing through the external reinforcing ribs of the cabinet, even if a small amount of water comes into contact with the welding area, the shape of the external reinforcing ribs can make the water flow away quickly instead of soaking in the welding area for a long time, thereby reducing the possibility of water penetrating into the cabinet.

[0019] This utility model discloses a cabinet lifting ring structure. The outer reinforcing ribs of the cabinet are in the shape of a "Z", which not only enhances the structural strength of the cabinet, but also reduces the possibility of weld cracking caused by long-term stress or environmental factors (such as wind, sun exposure, corrosion, etc.).

[0020] This utility model discloses a cabinet lifting ring structure. The outer reinforcing rib of the cabinet is fixed to the top plate of the cabinet by welding, which has high strength and reliability. It can make the outer reinforcing rib of the cabinet and the top plate of the cabinet form a whole, ensuring a firm connection under various working conditions.

[0021] This utility model discloses a cabinet lifting ring structure. The external reinforcing ribs of the cabinet are spot-welded to the connecting parts, and the external reinforcing ribs of the cabinet are welded to the top plate of the cabinet, which improves the ease of welding, reduces welding time, and improves welding efficiency.

[0022] This utility model discloses a cabinet lifting ring structure, which can shorten inspection time and reduce the production cost of charging piles. Attached Figure Description

[0031] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0032] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, such as a process, method, system, product, or apparatus comprising a series of steps or units, are not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0033] The present invention will now be described in further detail with reference to the accompanying drawings:

[0034] Example 1

[0035] This utility model provides a cabinet lifting ring structure, including a lifting ring 1, a cabinet outer reinforcing rib 2, a cabinet top plate 3, and a connector 4; the cabinet top plate 3 is located at the upper end of the charging pile cabinet, the cabinet outer reinforcing rib 2 is located on the side of the cabinet top plate 3 away from the charging pile, and is fixedly connected to the cabinet top plate 3, the lifting ring 1 passes through the cabinet outer reinforcing rib 2 from top to bottom and is fixedly connected to the connector 4, and the connector 4 is located inside the cabinet outer reinforcing rib 2.

[0036] like Figure 3 The multiple lifting rings 1 are divided into two groups and installed at both ends of the top plate 3 of the cabinet. Each lifting ring 1 includes a ring-shaped component and a fastener. The fastener is a solid cylinder, with its upper end fixedly connected to the ring-shaped component and its lower end passing through the outer reinforcing rib of the cabinet and connecting to the connector 4. The fixed connection here is welded. A boss is provided at the connection between the ring-shaped component and the fastener. The diameter of the boss is larger than the diameter of the fastener, ensuring that when the lifting ring 1 is sprayed with external liquid, the liquid flows through the ring-shaped component and the boss to the surface of the outer reinforcing rib 2 of the cabinet.

[0037] When rainwater falls on the top of the charging pile or the water on the lifting ring 1 flows downward, the external stiffeners 2 of the cabinet can guide the water to the edge of the cabinet like a water trough, preventing water from accumulating on the top of the cabinet or entering the interior of the cabinet through welding seams, etc. This natural diversion effect can effectively reduce problems such as corrosion and short circuits caused by water accumulation in the cabinet.

[0038] The connection between the annular part and the fastener is smooth and free of burrs. When hoisting or moving the charging pile and other operations are carried out, if there are burrs that catch other objects, it may cause the equipment to shift, the cable to break, or the tool to be damaged; the burrs will make the stress distribution at the connection uneven. When bearing tensile or compressive forces, the stress will concentrate around the burrs, easily causing cracks or fatigue damage at the connection part. The smooth connection part can make the stress evenly distributed and extend the service life of the annular part and the fastener.

[0039] The upper end face of the external stiffener 2 of the cabinet is provided with a first through hole, and the shape and size of the first through hole are adapted to those of the fastener, so that the lifting ring 1 can be inserted into the external stiffener 2 of the cabinet. In addition, the distance between the upper end face and the lower end face of the external stiffener 2 of the cabinet should be greater than the height of the fastener to prevent the bottom surface of the lifting ring 1 from rubbing against the upper end face of the cabinet top plate 3 and reduce the service life.

[0040] As Figure 4 shown, the overall shape of the external stiffener 2 of the cabinet is in a U-shape. When the charging pile is subjected to an external lateral force, such as jolting during transportation, swinging during hoisting, or the action of strong wind outdoors, it can effectively resist bending. Under the bending stress, the upper and lower parallel parts can bear greater tensile and compressive stresses, and the middle connecting part can effectively disperse these stresses, thereby enhancing the bending stiffness.

[0041] When the charging pile is subjected to a vertical pressure, such as when stacking other equipment or being pressured by an object above like a roof, the U-shaped external stiffener 2 of the cabinet can provide good compressive performance. The upper and lower parallel parts can evenly distribute the pressure to the side plate and the top plate, and the middle bent part can prevent local excessive deformation, similar to a buffer structure, ensuring that it will not easily dent or be damaged when bearing pressure.

[0042] The U-shaped external stiffener 2 of the cabinet is fixed to the cabinet top plate 3 by welding, and the external stiffener 2 of the cabinet and the connecting piece 4 are spot welded, which can reduce the risk of water leakage caused by welding seams. During the process of water flowing through the external stiffener 2 of the cabinet, even if a small amount of water touches the welding part, the shape of the external stiffener 2 of the cabinet can make the water flow away quickly instead of being soaked at the welding place for a long time, thereby reducing the possibility of water penetrating into the interior of the cabinet.

[0043] The connector 4 is installed inside the outer reinforcing rib 2 of the cabinet. The upper end face of the connector 4 is spot-welded to the upper end face of the inner cavity of the outer reinforcing rib 2. Multiple weld points are evenly distributed between the upper end face of the connector 4 and the upper end face of the inner cavity of the outer reinforcing rib 2, which can distribute the external force relatively evenly. Compared with the use of large-area continuous welding, this method can ensure the connection strength while avoiding structural deformation caused by the concentration of welding thermal stress.

[0044] In summary, this utility model provides a cabinet lifting ring structure in which the connector 4 is installed inside the outer reinforcing rib 2 of the cabinet. The outer reinforcing rib 2 and the lifting ring 1 are arranged from bottom to top on the upper end of the cabinet top plate 3. The lifting ring 1 passes through the outer reinforcing rib 2 and is threadedly connected to the connector 4. In this embodiment, the connector 4 is a welded nut.

[0045] A charging pile includes a charging pile cabinet and the aforementioned cabinet lifting ring structure, the cabinet lifting ring structure being located at the top of the charging pile cabinet.

[0046] Example 2

[0047] This utility model discloses a method for using a cabinet lifting ring structure. The lower end of the lifting ring 1 passes through the circular through hole on the outer reinforcing rib 2 of the cabinet and is first threadedly connected to the connector 4. Then, using a tool, the end of the connector 4 away from the top plate of the cabinet is electrically welded to the upper end face of the inner cavity of the outer reinforcing rib 2. Finally, using a tool, the lower end face of the outer reinforcing rib 2 is welded to the top plate 3 of the cabinet.

[0048] Specifically, pass the lower end of the lifting ring 1 through the circular through hole on the outer reinforcing rib 2 of the cabinet, so that the threaded portion of the lower end of the lifting ring 1 protrudes from the circular through hole. Then, take the connector 4 and align its threaded end with the threaded portion of the lifting ring 1. Use a wrench to gradually rotate the connector 4 to make it threadedly connected to the lifting ring 1. During the tightening process, ensure that the threads are fully engaged and the connection is secure. At the same time, check for any looseness by visual inspection and by gently pulling the lifting ring 1 by hand until the appropriate tightness is achieved, ensuring that the lifting ring 1 will not detach from the connector 4 under normal stress.

[0049] After completing the threaded connection, the operator puts on protective gear, starts the welding equipment, and adjusts the welding parameters (such as welding current and voltage, which should be set appropriately according to the actual steel thickness and welding rod type). The end of the connector 4 furthest from the top plate 3 of the cabinet is placed against the upper surface of the inner cavity of the outer reinforcing rib 2 of the cabinet, ensuring good contact. Then, using a welding gun, spot welding is performed at the contact area according to the predetermined weld point distribution. Multiple weld points are evenly formed on the connecting surface, ensuring full welds and appropriate penetration depth. During the welding process, the weld quality is checked continuously using tools such as a weld inspection ruler to ensure that the connector 4 and the outer reinforcing rib 2 form a strong connection through welding, capable of jointly withstanding external forces, and that the welds have a smooth appearance without obvious welding defects.

[0050] The outer reinforcing rib 2, with the lifting ring 1 and connector 4 already connected, is placed at the predetermined position on the top plate 3 of the cabinet, ensuring the lower end face of the outer reinforcing rib 2 is tightly fitted against the top plate 3. Temporary fixation is achieved using clamps or other tools to prevent displacement during welding. Next, using welding equipment, continuous welding is performed along the contact edge between the outer reinforcing rib 2 and the top plate 3, forming a continuous weld. During welding, the welding speed and angle must be carefully controlled to ensure uniform weld width and height, avoiding welding quality issues such as porosity, slag inclusions, and incomplete penetration. After welding, the weld is visually inspected and subjected to non-destructive testing (such as ultrasonic testing) to ensure the welding quality meets requirements, firmly bonding the outer reinforcing rib 2 to the top plate 3, providing reliable structural reinforcement and stable support.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the specific implementation of this utility model. Any modifications or equivalent substitutions that do not depart from the spirit and scope of this utility model should be covered within the protection scope of the claims of this utility model.
