Description

Technical Field

[0001] The present invention relates to the technical field of power equipment packaging, and particularly to a steel frame packaging structure for insulators with stable structure, good protection performance and convenient transportation and storage. Background Art

[0002] As an indispensable key component in the power system, insulators play a crucial role in high-voltage and extra-high-voltage transmission lines. Its core function is to support the conductors and maintain insulation, thus ensuring the safe and stable operation of the power system. There are various types of insulators, and the commonly used ones in current applications include porcelain insulators and composite insulators. Porcelain insulators are renowned for their excellent mechanical strength, outstanding insulation performance and excellent weather resistance; at the same time, composite insulators integrate the advantages of organic and inorganic materials, and have won wide acclaim in the industry with their light weight, high strength and excellent anti-pollution performance.

[0003] Due to the irregular shape and vulnerability of insulators, they are prone to physical damage, pollution and moisture absorption during storage and transportation. In terms of physical damage, minor collisions or drops may cause cracks or fractures in the insulators, seriously affecting their performance; while dirt and humid environments will reduce the insulation performance and increase the failure risk of insulation components and related lines. Therefore, the protection and transportation of insulators face severe challenges. Among them, ensuring the structural integrity and performance stability of insulators during transportation and storage is the core issue concerned in the technical field of power equipment packaging.

[0004] In view of the above factors, a reasonable packaging structure is crucial for the protection of insulators. At present, there are mainly two packaging methods for insulators: wooden frame packaging and customized bracket packaging. Among them, although wooden frame packaging provides a certain degree of protection, its strength and stability are limited, and the wooden materials are prone to moisture and mildew, which may have an adverse impact on the storage environment and increase the damage risk of insulators; although customized bracket packaging is highly targeted and can provide precise support and protection, it has a high cost and poor versatility, and it is difficult to meet the needs of insulators of different specifications. In addition, for large-size and extra-large-size insulators that are huge in volume and heavy in weight, in addition to bearing huge weight and pressure, the packaging structure also needs to prevent collisions, frictions and contaminations during transportation to ensure the integrity of the insulators. This makes the design requirements of the corresponding packaging structure more complex and delicate. In addition to excellent load-bearing capacity and stability, special needs of large-size and extra-large-size insulators must be considered, and multiple protection measures such as anti-slip and shock absorption must be added to ensure their safety in complex transportation environments.

[0005] In addition, the packaging structure should have excellent disassembly, reusability, and the ability to adapt to insulators of various sizes, so as to facilitate disassembly and reorganization according to requirements. Through modular design, not only the installation and disassembly become simple, but also it can be adjusted according to different insulator specifications, flexibly meeting the packaging needs of various insulators. This ensures the safety and reliability of insulators during long-distance transportation and in variable environments, while also effectively reducing transportation costs and improving the overall packaging efficiency. Summary of the Invention

[0006] The technical problem solved by the present invention is to provide a steel frame packaging structure for insulators, which is dedicated to the protection and transportation of large-size and extra-large-size insulators, can effectively improve the transportation safety and stability of insulators, reduce losses and costs, and has good versatility and adaptability, suitable for insulators of various specifications, and can be used to solve the defects in the above technical background.

The wooden sleeper structures have concave arc surfaces on the opposite side surfaces, and clamping screws are correspondingly installed on both sides of the concave arc surfaces.

By inserting pin fixing pieces into the pin holes, the upper and lower packaging units can be tightly connected and fixed, ensuring the stability and safety of the overall packaging structure.

[0011] As a further limitation, multiple load-bearing bridge frames are arranged in the width direction of the inner cavity of the frame support, so that multiple insulators to be packaged can be placed at intervals in the width direction of the inner cavity of the frame support.

The base is a liftable base and is fixed on the load-bearing bridge frame. The plate frame is a flat plate structure and is connected to the base through a hinged structure. The plate plane of the plate frame is perpendicular to the axial direction of the insulator to be packaged, and the plate width matches the distance between the bottom umbrella skirts of the insulator to be packaged, and an arc-shaped groove matching the bottom umbrella skirts of the insulator is formed on the top surface of the plate body, so as to support and fix the composite insulator at the position between the umbrella skirts of the insulator umbrella skirt.

[0014] As a further limitation, a guide frame is provided on the load-bearing bridge in the length direction, and the support assembly is arranged on the guide frame through a sliding seat with a locking mechanism, so that the corresponding support assembly can adjust the position by sliding on the load-bearing bridge through the combination of the guide frame and the sliding seat.

[0015] As a further limitation, anti-slip pads and locking devices are respectively provided at both ends of the clamping screw to ensure that the screw does not slide during the tightening process and effectively fix the insulator; and a torque amplifier is provided at least at one end to assist in the locking operation of the clamping screw, ensuring uniform and stable clamping force, and improving the overall packaging efficiency and safety.

Detailed Embodiments

[0021] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below with reference to specific drawings.

[0022] It should be noted that the embodiments in the specification, claims and the above-mentioned drawings of the present invention can be implemented in an order other than those illustrated or described herein. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device comprising a series of steps or units need not be limited to those steps or units clearly listed.

[0023] In addition, the embodiments shown in the content of this specific implementation manner are only one of the implementation forms that the present invention can exhibit, and do not represent all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] See Figures 1 - 2 A first preferred embodiment of a steel frame packaging structure for insulators. In this embodiment, the steel frame packaging structure shows the basic structural form under the technical conditions of the present invention. In this structural form, the steel frame packaging structure is formed by stacking multiple packaging units up and down and completing fixed assembly. Figure 1 The stacked form of its upper and lower two packaging units is shown. And a single packaging unit can be used to place two insulators 5 to be packaged side by side and complete position fixing.

[0025] In Figure 1 , Figure 2 Under the conditions of the shown embodiment form, a single packaging unit includes an outer structural bracket and a support assembly. Its outer structural bracket mainly serves as an outer support and protection structure for withstanding external pressure. The support assembly provides bottom support and positioning fixation for the insulator 5 to be packaged to ensure the stability and safety of the insulator 5 to be packaged within the outer structural bracket.

[0026] The outer structural bracket of this embodiment is an overall rectangular frame bracket structure. The main body part is composed of an upper cross beam 2, a lower cross beam 7 and a vertical beam 17. The upper cross beam 2 and the lower cross beam 7 are both I-beam structures, and the vertical beam 17 is a rectangular steel pipe. During forming, first, the upper cross beam 2 and the lower cross beam 7 with corresponding lengths are respectively erected to form the upper rectangular frame and the lower rectangular frame, and then the four corner positions of the corresponding rectangular frames are connected and fixed by using angle assembly blocks 1 and assembly bolts. After connection and fixation, the vertical installation of the vertical beam 17 is completed on the angle assembly block 1 to form an overall stable rectangular frame outer skeleton structure.

[0027] After the installation of the main part of the outer structural support is completed, a load-bearing bridge 20 is arranged along the length direction on the inner side of the lower rectangular frame surrounded by the corresponding lower cross beam 7. In this embodiment, there are two load-bearing bridges 20, which are respectively arranged below the packaging and fixing positions of the insulators 5 to be packaged. The load-bearing bridges 20 are arranged along the length direction of the outer structural support (corresponding to the axial direction of the insulators 5 to be packaged). Both ends of the load-bearing bridges 20 are firmly connected to the lower cross beam 7 and are equipped with reinforcing ribs to ensure that the bridges remain stable when bearing the weight of the insulators, and maintain their stability even under complex transportation conditions.

[0028] In addition, the load-bearing bridge 20 of this embodiment has an isosceles trapezoidal cross-section. On the one hand, its cross-section design can effectively disperse pressure and enhance the load-bearing capacity. On the other hand, it is convenient to arrange guide rails and support components with sliding seats on the bottom surface through the guide rail surface. And the corresponding support components are provided with locking mechanisms at the sliding seat positions, and the locking mechanisms can be used to lock the adjusted positions of the support components on the load-bearing bridge 20 to ensure that the support components will not shift on the guide rails of the load-bearing bridge 20 during transportation and affect the support stability of the insulators 5 to be packaged.

[0029] In this embodiment, the outer structural support can be assembled by selecting upper cross beams 2, lower cross beams 7 and vertical beams 17 with different lengths to cooperate with the corner assembly blocks 1, so as to obtain packaging units with different sizes and load-bearing capacities to meet the packaging requirements of different specifications of insulators. This can effectively improve the versatility and flexibility of the packaging unit, reduce production costs, and ensure the safety and stability of various insulators during transportation. At the same time, after single use, each component can be disassembled and reused to reduce resource waste, which conforms to the environmental protection concept.

[0030] In addition, in this embodiment, a vertical rod 8 is also arranged on the outer side of the corresponding vertical beam 17 of the outer structural support. The vertical rod 8 abuts against the vertical beam 17 during assembly, and the vertical rod 8 and the vertical beam 17 in the abutting state are firmly connected by fixing bolts. On the one hand, the vertical rod 8 can assist in improving the load-bearing performance of the vertical beam 17. On the other hand, matching plug joints 16 and plug holes are formed at the top and bottom of the vertical rod 8. The plug joints 16 match the plug holes, so that the upper packaging unit and the lower packaging unit can be positioned and overlapped up and down to ensure the stability of the overall structure. After the upper and lower packaging units are assembled, the upper and lower packaging units can be tightly connected by inserting pin fixing pieces into the pin holes reserved at the corresponding positions on the vertical rod 8, further improving the stability and safety of the overall packaging structure.

[0031] In this embodiment, in the upper and lower rectangular frames assembled and combined by the upper cross beam 2 and the lower cross beam 7, positioning pads 4 are respectively arranged at intervals at the web positions corresponding to the upper cross beam 2 and the lower cross beam 7. These positioning pads 4 not only enhance the support of the upper cross beam 2 and the lower cross beam 7 at the spaced positions, but also serve as the positioning reference for the assembly of the connecting rod 6, facilitating the connection and enhancement between the upper and lower rectangular frames by using the connecting rod 6. The lower rectangular frame built by the lower cross beam 7 and the vertical beam 17 are connected and enhanced by the diagonal brace 18 formed by the angle steel strip. The combination of the connecting rod 6 and the diagonal brace 18 can effectively improve the rigidity and stability of the overall structure, ensure that each component bears force cooperatively during transportation, and avoid structural deformation caused by local stress concentration, thereby further ensuring the safe transportation of the insulator. In another embodiment, the reinforcement structure between the structural edges of the frame support of this outer structural support can also be replaced by a truss or other equivalent structural forms to adapt to different packaging requirements and transportation environments.

[0032] In this embodiment, the vertical beam 17, the upper cross beam 2, the lower cross beam 7, the connecting rod 6, and the diagonal brace 18 that make up the outer structural support are all formed of steel structure materials, and an anti-corrosion coating is also applied on the material surface to improve its durability and corrosion resistance in various environments and extend its service life.

[0033] In addition, a tarpaulin fixing frame 3 is provided on the outer sides corresponding to the upper cross beam 2 and the lower cross beam 7 of the outer structural support of this embodiment. The tarpaulin fixing frame 3 is provided with reserved fixing holes. The setting of the tarpaulin fixing frame 3 facilitates covering a rainproof cloth outside the packaging structure, so as to install the rainproof cloth under bad weather conditions, effectively protecting the insulator from rain erosion and ensuring the dryness and safety of the insulator 5 to be packaged during transportation.

[0034] Under the structural conditions of this embodiment, considering that the insulator 5 to be packaged itself has a small size and a high structural strength, only two end support assemblies are provided in the support assembly of this embodiment. The two end support assemblies are respectively arranged at the positions corresponding to the front side end fitting 9 and the rear side end fitting 15 at both ends of the insulator 5 to be packaged.

[0035] The end support assembly includes a base 19 and a support structure formed on the base 19. The base 19 is a square tube structure, and an assembly position matching the support structure on the end support assembly is provided thereon. The end support assembly is mounted on the carrying bridge 20 through the base 19 and can be adjusted in position along the carrying bridge 20 to adapt to insulators 5 to be packaged with different lengths.

[0036] The support structure includes an assembly part 10 and a fixed bearing part. In this embodiment, the assembly part 10 is an L-shaped steel plate structure, its horizontal side is assembled and connected with the base 19 through threaded connectors, and its vertical side is perpendicular to the axis of the insulator 5 to be packaged.

[0037] The assembly part 10 of the end face support assembly corresponding to the position of the front end face fitting 9 abuts against the front side of the front end face fitting 9, while the assembly part 10 of the end face support assembly corresponding to the position of the rear end face fitting 15 abuts against the rear side of the rear end face fitting 15. The assembly part 10 is closely attached to the side face of the end face fitting, and a stable connection is formed with the corresponding end face fitting through the assembly structure thereon. Specifically in this embodiment, considering that both the front end face fitting 9 and the rear end face fitting 15 are flange-type assembly structures, therefore, the assembly structure on the assembly part 10 is a threaded assembly hole seat matching the flange-type assembly structure on the corresponding side end face fitting, and the corresponding threaded assembly hole seat is formed on the concave arc surface on the vertical side of the assembly part 10 in the style as Figure 2 ,, Figure 3 shown, and this concave arc surface matches the flange assembly surface of the corresponding end face fitting, and can ensure the close fit and stable connection between the assembly part 10 and the corresponding side end face fitting through the assembly of fastening bolts.

[0038] The fixed bearing part includes a pair of upper and lower wooden sleeper structures, namely the lower wooden sleeper 11 and the upper wooden sleeper 12. The wooden sleeper structures have concave arc surfaces on the opposite side faces, and the design of the concave arc surfaces perfectly fits the outer shape of the end face fitting, further enhancing the stability of the support. On both sides of the concave arc surface, clamping screws 14 are correspondingly installed. The upper part of the clamping screw 14 is pre-tightened with a nut, and the lower part is installed on the base 19. The setting of the clamping screw 14 not only realizes the upper and lower clamping of the end face fitting, but also is fixed to the base 19 through the clamping force applied by it, ensuring the stability and safety of the insulator 5 to be packaged during transportation. In another embodiment, in order to improve the convenience of using the clamping screw 14, anti-slip pads and locking devices are respectively provided at both ends of the clamping screw to ensure that the screw does not slide during the tightening process, so as to effectively fix the insulator 5 to be packaged through the wooden sleeper combination of the fixed bearing part. In addition, it can also be considered to set a torque amplifier at the upper end of the clamping screw 14 to assist the locking operation of the clamping screw 14, ensure that the clamping force is uniform and stable, and improve the overall packaging efficiency and safety In this embodiment, the assembly structure design of the assembly part 10, the fixed bearing part and the base 19 can enable the corresponding assembly part 10 and the fixed bearing part to be quickly assembled and disassembled with the base 19 through a detachable connection method. This not only facilitates the assembly and maintenance of the packaging structure, but also enables component recycling, effectively reducing the operation and maintenance costs of insulator packaging and transportation. At the same time, the assembly design also enables the support assembly to be flexibly adjusted according to different specifications of insulators, further enhancing the versatility and adaptability of the packaging structure.

[0039] In this embodiment, the use of the steel frame packaging structure allows the operator to select an appropriate support component and assembly method according to the specific size and shape of the insulator 5 to be packaged. After selecting the support component and assembly method, first use the lower crossbeam 7 to construct the lower rectangular frame, and complete the assembly of the load-bearing bridge 20 and the installation of the support components on the load-bearing bridge 20 within the frame. After the assembly is completed, use the lifting equipment to lift the insulator 5 to be packaged to the fixed load-bearing position of the support component, and then adjust the position of the base 19 to ensure that the assembly part 10 is closely attached to one side of the end fitting, and reinforce it by bolt connection. Next, place the upper and lower wooden sleeper structures on the inner and outer sides of the assembly part 10 respectively, and clamp and fix them with the clamping screw 14. Finally, check the firmness of all connection parts to ensure the stability and safety of the packaging structure during transportation.

[0040] In addition, if the method of this embodiment is adopted and only the end face support components on both sides are set to carry and fix the insulator 5 to be packaged, the corresponding insulator 5 to be packaged can also adopt additional protection measures such as the protective coating 13 at the umbrella skirt section to further improve the safety and stability of the insulator during transportation. The setting of the protective coating 13 can effectively prevent the insulator from being damaged by external factors such as collision and friction during transportation, thus ensuring the integrity and long service life of the insulator.

[0041] In another embodiment, if the size of the insulator 5 to be packaged is large or higher structural strength is required to ensure transportation safety, intermediate support components can also be set on the load-bearing bridge 20 as needed. The corresponding intermediate support components are arranged between the end face support components on both sides, and multiple intermediate support components can be arranged along the direction of the load-bearing bridge 20 according to needs, and are used to support the bottom surface of the insulator to be packaged at the skirt section between the umbrella skirts of the insulator 5 to be packaged.

[0042] To achieve the above functions, the corresponding intermediate support assembly includes a base 19 and a plate frame. The plate frame is a flat plate structure, hinged to the base 19 through a hinge. After the plate frame is overturned through the hinge, the corresponding intermediate support assembly can be cancelled; the plane of the plate body of the plate frame is perpendicular to the axis of the insulator 5 to be packaged, and the width of the plate body matches the spacing between the bottom umbrella skirts of the insulator 5 to be packaged. An arc-shaped groove matching the bottom umbrella skirts of the insulator 5 to be packaged is provided on the top surface of the plate body, so as to support and fix the insulator 5 to be packaged at the position of the inter-umbrella area of the insulator umbrella skirts. Considering the size and structural differences of the insulator 5 to be packaged, there are differences in the installation positions and support height positions of different intermediate support assemblies on the load-bearing bridge 20. On the one hand, the base 19 of the corresponding intermediate support assembly can slide on the load-bearing bridge 20 and adjust the position in the same way as the base 19 of the end face support assembly. On the other hand, the base 19 can also be set as a liftable base, and the height can be adjusted to meet the requirements of different insulators, ensuring that each support point can be accurately aligned, so as to maximize the stability and adaptability of the overall packaging structure.

[0043] In Figure 3 In another embodiment shown, it is also possible to choose to set the load-bearing bridge 20 in the upper rectangular frame of the upper beam 2 assembly combination in the same way as the lower rectangular frame. When setting the load-bearing bridge 20 in the upper rectangular frame, the number of the corresponding load-bearing bridges 20 set is one group less than the number of the load-bearing bridges 20 set in the lower rectangular frame, so that the projection of the load-bearing bridge 20 set in the upper rectangular frame is located between the load-bearing bridges 20 with adjacent positions in the lower rectangular frame. The load-bearing bridge 20 set in the upper rectangular frame can also be used to arrange the support assembly, and carry out the assembly, loading and fixing of the insulator 5 to be packaged. The style after its assembly and loading is as Figure 3 shown.

[0044] Figure 3 The structural form of the embodiment shown is only used for packaging and transportation in the uppermost layer of the multi-layer stacked packaging unit or when the packaging unit is not stacked.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention.
