Description

Technical Field

[0001] This utility model belongs to the field of packaging box technology, and relates to a GIS cable outlet sleeve packaging box. Background Technology

[0002] Gas-insulated metal-enclosed switchgear (GIS) is an important component of power systems. GIS outgoing bushings, as key components of GIS equipment, are used to connect the GIS equipment to external transmission lines, ensuring the safety and reliability of power transmission. They are widely used in overseas high-voltage and ultra-high-voltage transmission systems. During export transportation, due to the need for sea and road transport and the handling of standard containers, proper protection is required for the GIS outgoing bushings to prevent damage to the packaging and the bushings themselves.

[0003] Existing packaging materials, due to insufficient consideration of container loading and unloading processes, present the following problems when cranes or other lifting equipment cannot be used and forklifts are the only option: 1. Insufficient protection of key stress-bearing areas of the container: During the process of loading the container into the container, only horizontal dunnage is used, which can easily cause scratches and damage to the container's floor. 2. Unfixed stress points: During the process of moving the container out of the container, the stress points of the dragging ropes are not fixed, or they are tied to unintended structures, causing concentrated stress and structural damage. Utility Model Content

[0004] The purpose of this utility model is to solve the technical problems of insufficient protection of key stress-bearing parts of the GIS outgoing sleeve packaging box and the inconsistent stress position in the existing technology, and to provide a GIS outgoing sleeve packaging box.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] In a first aspect, this utility model discloses a GIS outgoing sleeve packaging box, including a packaging box body, wherein a card plate that cooperates with the GIS outgoing sleeve is provided in the packaging box body; drag straps are provided at both ends of the bottom of the packaging box body; and wooden blocks are provided at the bottom of the packaging box body, wherein the wooden blocks include a plurality of transverse wooden blocks and longitudinal wooden blocks arranged between the transverse wooden blocks.

[0007] Further improvements are made in the following aspects:

[0008] The packaging box body includes a bottom support, side plates are provided on both sides of the bottom support, and end plates are provided at both ends of the bottom support; a cover plate is provided on the top of the rectangular structure formed by the side plates and end plates, which is opposite to the bottom support.

[0009] The support includes skids on both sides and a base plate disposed between the skids on both sides; the two ends of the tow strap are respectively fixed to the skids on both sides.

[0010] A pressure plate is also provided at the connection between the tow strap and the skid to press the tow strap against the inside of the skid.

[0011] The transverse pad is fixed to the skid by wood screws, which pass through the transverse pad and penetrate more than two-thirds of the skid.

[0012] The two transverse blocks at both ends of the packaging box have gaps between them and their adjacent transverse blocks, and no longitudinal blocks are installed.

[0013] The height of the two transverse blocks located at both ends of the packaging box is 8 mm-12 mm lower than the height of the other transverse blocks.

[0014] The horizontal blocks adjacent to the two horizontal blocks located at both ends of the packaging box have chamfered edges.

[0015] The chamfer is a C20 chamfer.

[0016] The towing strap is a nylon towing strap.

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

[0018] This utility model discloses a packaging box for GIS cable outlet sleeves. Towing straps are installed at both ends of the bottom of the packaging box body. This transforms the force of the forklift pushing the packaging box during towing into the pulling force of the towing straps, thereby preventing damage to the end plates of the packaging box caused by the pushing force of the forklift, which could lead to damage to the packaging box or even the GIS cable outlet sleeves inside. Wooden blocks are provided at the bottom of the packaging box body. These blocks include several transverse blocks and longitudinal blocks placed between the transverse blocks. This transforms the force on individual transverse blocks during towing into a unified force distribution, thus dispersing the force and greatly improving the stability of the structure.

[0019] Furthermore, the drag strap is securely fixed to the inside of the skid using two sets of wood screws via a pressure plate. When the drag strap is under stress, the skid bears all the force. The skid is the strongest component and the most desirable stress-bearing part of the packaging box structure.

[0020] Furthermore, the two transverse wooden blocks at both ends of the packaging box have gaps between them and their adjacent transverse wooden blocks, without longitudinal wooden blocks. This allows lifting ropes to pass through when cranes or other lifting equipment are needed for transport in other stages. The height of the two transverse wooden blocks at both ends of the packaging box is 8 mm-12 mm lower than the other transverse wooden blocks. The transverse wooden blocks adjacent to the two transverse wooden blocks at both ends of the packaging box have chamfered edges. The first transverse wooden block on each side bears a large amount of friction when the box is dragged or pushed, but because there are no longitudinal wooden blocks, this friction cannot be distributed. To avoid this, the first transverse wooden block is designed to be lower than the other transverse wooden blocks. When the box is dragged or pushed, the first transverse wooden block is suspended, so no friction is applied to it. The friction is concentrated on the adjacent second transverse wooden block, which has chamfered edges. This chamfer prevents stress concentration when the box is subjected to friction, greatly reducing shear pressure and making it less likely to damage the box components. Attached Figure Description

[0034] Example 1

[0035] See Figure 1 , Figure 2 and Figure 3 This utility model discloses a GIS outgoing sleeve packaging box, including a packaging box body, in which a clamping plate 16 is provided to cooperate with the GIS outgoing sleeve; the bottom ends of the packaging box body are provided with drag straps 17; the drag straps 17 are nylon drag straps. The bottom of the packaging box body is provided with wooden blocks, the wooden blocks including a plurality of transverse wooden blocks 13 and longitudinal wooden blocks 12 disposed between the transverse wooden blocks 13. The packaging box body includes a bottom support 1, the bottom support 1 has side plates 2 on both sides, and end plates 4 at both ends; the rectangular structure formed by the side plates 2 and end plates 4 is provided with a cover plate 3 disposed opposite to the bottom support 1. The bottom support 1 includes skids 11 on both sides and a bottom plate disposed between the skids 11 on both sides; the two ends of the drag straps 17 are respectively fixed to the skids 11 on both sides. A pressure plate 18 is also provided at the connection between the drag straps 17 and the skids 11 for pressing the drag straps 17 against the inside of the skids 11. The transverse pad 13 is fixed to the skid 11 with wood screws, which pass through the transverse pad 13 and penetrate more than two-thirds of the way into the skid 11. The clamping plate 16 is connected to the skid 11 with M12 bolts, and all other connections are made with wood screws of varying lengths.

[0036] See Figure 4 The two transverse wooden blocks 13 located at both ends of the packaging box have gaps between them and their adjacent transverse wooden blocks 13, and no longitudinal wooden blocks 12 are provided. The height of the two transverse wooden blocks 13 located at both ends of the packaging box is 8 mm-12 mm lower than the height of the other transverse wooden blocks 13. The transverse wooden blocks 13 adjacent to the two transverse wooden blocks 13 located at both ends of the packaging box are provided with chamfers. The chamfers are C20 chamfers.

[0037] Example 2

[0038] Generally, a 550kV GIS outgoing bushing weighs approximately 1.5-3 tons, is about 6-8 meters long, 0.8-1.2 meters wide, and 0.9-1.5 meters high. Since exported products are mostly transported in standard containers, the internal dimensions of a 20-foot standard container are 5.898 x 2.352 x 2.393 meters, and those of a 40-foot standard container are 12.032 x 2.352 x 2.393 meters. Therefore, 550kV GIS outgoing bushings shorter than 5.8 meters are generally transported in 20-foot standard containers, while those longer than 6 meters should be transported in 40-foot standard containers.

[0039] Because the top of a standard container cannot be removed, cranes or other lifting machinery cannot be used to load and unload 550kV GIS outgoing bushings. Forklifts are required in this case. During the routine loading and unloading of exported 550kV GIS outgoing bushings from containers, situations frequently arise where inadequate packaging design makes loading and unloading difficult, leading to damage to the packaging and even the 550kV GIS outgoing bushings inside.

[0040] See Figure 1The packaging box includes a base 1, side panels 2 and 4, and a lid 3. The main component of the base 1 is the skid 11, which is the core load-bearing component of the packaging box and is generally made of high-strength pine such as larch or Douglas fir. For boxes with a width of less than one meter, two skids are typically used per box. If the box width exceeds one meter, a three-skid structure should be used. Several transverse dunnage 13s are laid at approximately one meter intervals at the bottom of the skids. The transverse dunnage 13s are connected to the skid 11s with wood screws. The wood screws should penetrate the transverse dunnage and reach at least two-thirds of the way into the skid to ensure strength. These transverse dunnage 13s ultimately come into direct contact with the bottom surface of the container when the box is placed inside the standard container. To prevent the transverse dunnage 13s from falling off due to friction, longitudinal dunnage 12s are placed between each transverse dunnage 13, so that the final friction force is borne as a whole, thus reducing the friction force distributed on each dunnage and preventing damage. A gap should be left between the first and second transverse blocks on each side, instead of using longitudinal blocks to fill the gap, because this is to accommodate the lifting of cranes and other lifting equipment during other stages of transport. Lifting ropes can pass through this gap. In this case, the first transverse block on each side bears a large amount of friction when the box is dragged or pushed, but because there are no longitudinal blocks, the friction force on the conductor cannot be distributed. This is obviously very disadvantageous. To avoid this situation, the first transverse block is designed to be 10 mm lower than the other transverse blocks. Thus, when the box is dragged or pushed, the first transverse block is suspended, and no friction force is applied to it. The friction force is concentrated on the second transverse block. The second transverse block is the chamfered transverse block 14. Clearly, it is ideal for the maximum friction force to be applied to the chamfered transverse block 14, which is also the designer's intention. Firstly, the chamfered transverse pads 14 are integrated with the longitudinal pads, distributing the friction across all pads and significantly reducing the friction on individual pads. Secondly, the chamfered transverse pads 14 have a C20 chamfer, preventing stress concentration when bearing friction, greatly reducing shear pressure and minimizing damage to the enclosure components. After the skids 11, transverse pads 13, longitudinal pads 12, chamfered transverse pads 14, end pieces 15, and clamping plates 16 are laid, the hollowed-out portion of the base is filled with 20mm thick boards to form a closed structure. A drag strip 17 is laid inside the skids 11, and a pressure plate 18 is attached. The base is now complete. The 550kV GIS outgoing bushing is then placed on the base 11. Note that the flanges of the 550kV GIS outgoing bushing are secured to their respective clamping plates, forming multi-point support. Next, attach side plate 2 and end plate 3. Use wooden blocks to secure them to the side plates inside the enclosure, primarily to prevent the 550kV GIS outgoing bushing from jumping up and down or moving back and forth.If necessary, an acceleration indicator can be installed to detect and record whether the maximum acceleration during transportation exceeds the value set by the acceleration indicator.

[0041] The installation method of this utility model is as follows:

[0042] After the GIS outgoing sleeve is installed into the bottom support 1 and fixed accordingly, two side plates 2 are attached to both sides, and two end plates 4 are attached to both ends. Finally, the cover plate 3 is attached to the top to complete the enclosure.

[0043] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
