Description

Technical Field

[0001] The invention belongs to the technical field of power transmission line emergency repair, and in particular relates to a device quick loading and unloading storage and transportation box body and a method thereof which also serves as a foundation of a power transmission line emergency repair tower. Background Art

[0002] Overhead transmission line repair towers are temporary replacement facilities for high-voltage transmission line towers that have been damaged due to ice, storms, foundation subsidence, external force damage or other accidents. They are designed to quickly restore power transmission and then restore or replace the damaged towers. Overhead transmission line repair towers are usually guyed towers, including tower sections, tower column bases, guyed foundations, guyed wires, connecting hardware, guyed wire connecting plates, mounting accessories, bolts, construction tools and other components, with a large number and specifications. As emergency repair materials, repair tower equipment has the following characteristics: First, the frequency of use is low and long-term storage is required; second, the line repair is urgent, and the transportation and loading and unloading time of the equipment should be shortened as much as possible; third, it needs to be recycled and reused after use, and requires repeated loading, unloading, handling and assembly. At present, the existing emergency tower equipment of power grid companies is usually stored in warehouses or outdoors, which are subject to problems such as poor management, missing parts, and exposure to wind and sun. A small amount of equipment is stored in containers, but the space utilization rate of conventional containers is not high. Loading and unloading requires manpower and entry and exit from the end doors, which makes it inconvenient to use cranes and has low loading and unloading efficiency.

[0003] The emergency repair tower is a guyed type. When subjected to external forces, the repair tower can be balanced and adjusted by guying. A base is hingedly connected to the bottom of the tower column. A fairly large floor is required under the base to sit on the ground to bear the full downward pressure of the emergency repair tower. Therefore, its own strength requirements are high and deformation is not allowed. At the same time, a large enough area is required to ensure that the foundation does not sink. In order to meet these two requirements, the foundation of the emergency repair tower is heavy and large, and it has to be assembled with steel sections to meet the requirements. Due to its large size, it may not fit in a conventional container, and it is heavy and difficult to load and unload. Summary of the invention

[0004] The purpose of the present invention is to address the problems in the above-mentioned prior art and to provide a quick loading and unloading storage and transportation box and method for equipment that also serves as the foundation of a power transmission line repair tower, so as to facilitate the loading and unloading of the repair equipment, integrate the repair equipment and the transport container into an integrated design, use the container chassis as the repair tower base, eliminate the need for separate design and processing of the repair tower base, simplify the equipment, and improve the repair efficiency.

[0012] As a preferred solution, the top layer of the box chassis platform structure is made of a steel plate or a wooden plate with a flat surface.

[0013] As a preferred solution, the connection between the middle layer and the bottom layer includes any one of bolt connection, rivet connection or welding.

[0014] In a second aspect, a method for constructing a fast loading and unloading storage and transportation box for equipment that also serves as a foundation for a power transmission line repair tower is provided, comprising: The equipment also serving as the foundation of the power transmission line repair tower is quickly loaded and unloaded into a storage and transportation box and transported to the operation site; At the work site, the main frame of the equipment quick loading and unloading storage and transportation box that also serves as the foundation of the power transmission line repair tower is disassembled from the box chassis, and the main frame is taken away; Stack the emergency repair equipment on the chassis of the box, use the chassis of the box as the foundation of the transmission line emergency repair tower, and erect the tower directly on the chassis of the box.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: The equipment quick loading and unloading storage and transportation box of the present invention, which also serves as the foundation of the power transmission line repair tower, adopts a split design for the main frame and the box chassis. The main frame is a rectangular cover with an opening on the bottom, and the box chassis is a platform structure.

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other.

[0020] In the description of the embodiments of the present invention, it should be understood that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred to modules or components must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0021] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit the technical solutions of this application.

[0022] Under extreme weather conditions, transmission lines may suffer tower collapse accidents due to natural disasters such as strong winds, heavy rains, ice and snow. Such accidents pose a serious threat to the stable operation of the power system and may cause large-scale power outages, affecting residents' lives and industrial production. In the face of such situations, it is crucial to quickly allocate emergency repair materials and start emergency repair work.

[0023] Overhead transmission line repair tower is a temporary replacement equipment for towers damaged by ice, storm, foundation subsidence, external force or other accidents in high-voltage transmission lines. It enables the damaged lines to quickly resume power transmission, and then restore or replace the damaged towers. Overhead transmission line repair towers are used to quickly restore the power transmission capacity of damaged lines and provide temporary support for the subsequent restoration or replacement of towers. Overhead transmission line repair towers need to have high bearing capacity and stability, and be able to withstand the weight of the transmission line and the influence of external climatic conditions. At the same time, the design structure is reasonable, easy to install and disassemble, and improve work efficiency. After the repair team arrives at the accident site, they assess the damage, select the appropriate repair tower according to the type and size of the damaged tower, and carry out necessary inspections and preparations. Under the guidance of professionals, the repair tower is installed in the designated location and ensured to be stable and vertical. After ensuring the stability of the repair tower, the transmission line is re-erected and power is restored.

[0024] As an emergency equipment, the overhead transmission line repair tower itself has a relatively low frequency of use. It is usually only needed when a serious fault occurs in the power system or a natural disaster causes line damage. Therefore, the repair tower needs to be properly stored and managed in peacetime to ensure that it can respond quickly when needed. During storage, it is necessary to pay attention to choosing a suitable storage environment. The repair tower should be stored in a dry, ventilated, and rain-proof place to prevent corrosion and damage. The repair tower should also be inspected and maintained regularly to ensure that its structure is intact, the connection is reliable, and the anti-corrosion layer has not fallen off. The repair towers are classified and stored according to their type, size, and purpose, so that the required repair towers can be found quickly. When a power system fails, the repair work is usually very urgent and power supply needs to be restored as soon as possible. Therefore, the transportation and loading and unloading time of the repair tower must be shortened as much as possible to ensure that the repair work can be carried out quickly. In order to shorten the transportation and loading and unloading time, the transportation route can be planned in advance to avoid traffic congestion and complex terrain to shorten the transportation time. According to the size and weight of the repair tower, choose a suitable transportation tool, such as a flatbed truck, crane, etc., to improve transportation efficiency. Equipped with professional loading and unloading teams and tools, such as cranes and forklifts, to quickly and safely complete the loading and unloading of the repair tower. The repair tower needs to be recycled and reused after use to reduce costs and reduce resource waste. Therefore, the repair tower needs to go through repeated loading, unloading, handling and assembly processes. In order to ensure the repeated use performance of the repair tower, the structural design of the repair tower should be easy to disassemble and assemble to reduce damage and wear during loading and unloading and handling.

[0025] The characteristics of the guyed type of emergency tower emphasize the importance of the hinged base under the tower column and the floor under the base. This design ensures that the emergency tower can stably withstand all the downward pressure and prevent structural deformation caused by foundation settlement. The base is the key connecting component between the emergency tower and the ground. It must be able to withstand the full downward pressure of the emergency tower and distribute it evenly to the ground. The base is usually made of high-strength, corrosion-resistant materials to ensure its stability and durability during long-term use. The floor is the supporting structure under the base. It must be large enough to ensure that the foundation of the emergency tower will not settle. The design of the floor should take into account the bearing capacity of the ground and the stability of the foundation to ensure that the emergency tower will not tilt or collapse during use. The material of the floor is usually also high-strength and corrosion-resistant to cope with harsh environmental conditions. The base and floor of the emergency tower must have high strength to withstand the full downward pressure of the emergency tower and possible external forces such as wind load and snow load. The strength requirement ensures that the emergency tower will not be structurally damaged or deformed during use, thereby ensuring the smooth progress of the emergency repair work. The base and floor of the emergency repair tower need to be designed with deformation in mind to ensure that they do not deform too much when under pressure. Excessive deformation may cause the structure of the emergency repair tower to become unstable or even collapse.

[0026] In order to solve the problems of low loading and unloading efficiency of traditional containers and the problems of heavy base and difficult loading and unloading of traditional emergency repair towers, an embodiment of the present invention proposes a fast loading and unloading storage and transportation box for equipment that also serves as the foundation of a power transmission line emergency repair tower.

[0027] like Figure 1 As shown, the equipment quick loading and unloading storage and transportation box that also serves as the foundation of the power transmission line repair tower in the embodiment of the present invention mainly includes a main frame 1 and a box chassis 2. The main frame 1 and the box chassis 2 adopt a split design. The main frame 1 is a rectangular cover with an opening at the bottom, and the box chassis 2 is a platform structure. The box chassis 2 can also serve as the foundation of the power transmission line repair tower. The main frame 1 and the box chassis 2 are detachably connected. When arriving at the work site, the main frame 1 and the box chassis 2 are disassembled, the main frame 1 can be lifted away by a crane, and the repair equipment can be directly stacked on the box chassis 2. The repair equipment is fully exposed, which is convenient for the use of cranes, forklifts or manual loading and unloading equipment, and will not be limited by the space limitations of traditional container bodies. The embodiment of the present invention integrates the repair equipment and the transport container into an integrated design, and the box chassis 2 also serves as the foundation of the power transmission line repair tower. In view of the urgent task of line repair, simplifying the number and types of equipment is a very important and effective means. The box chassis 2 designed in the embodiment of the present invention is large and strong, and is specially designed as the foundation of the power transmission line repair tower, which can avoid the need for separate design and processing of the base and related transportation, thus solving the problem that the traditional base is bulky and difficult to load and unload.

[0028] In a possible implementation, the main frame 1 of the embodiment of the present invention includes a box top 11, two front and rear end panels 12, and two side panels 13, and a rectangular cover with an open bottom is formed by the box top 11, the two front and rear end panels 12, and the two side panels 13. Further, the box top 11, the two front and rear end panels 12, and the two side panels 13 of the embodiment of the present invention are all made of corrugated steel plates, the two front and rear end panels 12 and the two side panels 13 are connected by four columns 14, and the box top 11 and the two side panels 13 and the box top 11 and the two front and rear end panels 12 are connected by crossbeams 15.

[0029] In a possible implementation, the bottoms of the front and rear end panels 12 and the two side panels 13 of the embodiment of the present invention are provided with a ring beam 16 connected together, and the bottoms of the end panels 12 and the side panels 13 are detachably connected to the edge of the box chassis 2 through the ring beam 16. Furthermore, the detachable connection is a bolt connection.

[0030] According to the above description of the embodiment of the present invention, the crossbeam 15 is usually made of steel, and other materials such as aluminum alloy are also used. The manufacturing process includes processes such as cutting, welding and surface treatment of steel. The column 14 is mainly located on the four sides of the container. It is an important part of the container's weight-bearing and pressure-resistant capacity, and plays a key role in bearing the vertical load of the container. The column 14 is usually made of steel, and its diameter and thickness are determined according to the size and purpose of the container. The column 14 is fixedly connected by welding or the like, and the upper crossbeam 15 and the lower ring beam 16 are located above and below the column 14 to enhance the load-bearing capacity of the column 14. The end of the column 14 can be provided with a bottom angle, which is usually welded by steel plates to fix the column 14 and the upper crossbeam 15 and the lower ring beam 16. In a possible embodiment, the container can also be provided with special columns, such as the front corner column and the rear corner column of the container, and these columns have specific sizes and shapes to meet the special needs of the container. The cross beam 15, the column 14 and the ring beam 16 together form the skeleton structure of the container, which ensures the overall stability and carrying capacity of the container. During transportation, the container can be effectively prevented from deformation and vibration, and the goods inside can be protected from external impact and damage.

[0031] In a possible implementation manner, a swing door is provided on one of the side panels 13 of the main frame 1 of the embodiment of the present invention.

[0032] See also Figures 2 to 5The platform structure of the box chassis 2 of the embodiment of the present invention is composed of at least three layers. The box chassis 2 functions as the bottom of the storage and transportation box, and can be used to disassemble the upper structure and cargo. It can also be used as the base structure of the emergency repair tower to withstand the downward pressure of the main column of the emergency repair tower. Structurally, the box chassis 2 can adopt a steel assembly structure, or a steel plate structure can be used instead of a profile. A number of main profiles are arranged in parallel in the length direction, and a number of auxiliary profiles are arranged in parallel in the width direction. The main profiles and the auxiliary profiles are preferably arranged vertically, and can also be arranged at an angle ranging from 30° to 150°. In the specific arrangement, the main profile is one layer and the auxiliary profile is one layer. The main profile can be on the top and the auxiliary profile can be on the bottom, or the auxiliary profile can be on the top and the main profile can be on the bottom.

[0033] In a possible implementation, the middle layer 22 and the bottom layer 23 of the platform structure of the box chassis 2 adopt a steel assembly structure, the middle layer 23 is arranged along the length direction of the box, and the bottom layer 23 is arranged along the width direction of the box; or, the middle layer 23 is arranged along the width direction of the box, and the bottom layer 23 is arranged along the length direction of the box. The middle layer 22 is used to bear the bending moment of the foundation rotating around the minor axis, and is the main load-bearing component, and is arranged in parallel with large-sized I-beams; the bottom layer 23 is used to bear the bending moment of the foundation rotating around the major axis, and is arranged in parallel with small-sized profiles (square tubes, I-beams, angle steels, channel steels, etc.); or, the bottom layer 23 is used to bear the bending moment of the foundation rotating around the minor axis, and is the main load-bearing component, and is arranged in parallel with large-sized I-beams; the middle layer 22 is used to bear the bending moment of the foundation rotating around the major axis, and is arranged in parallel with small-sized profiles (square tubes, I-beams, angle steels, channel steels, etc.).

[0034] According to the above description of the embodiment of the present invention, the size range of large-size I-beams is relatively large and is usually used in occasions where large loads need to be borne. The shape is an I-beam, with a large cross-sectional area, which can provide good bearing capacity and stability. The size range of small-size profiles is relatively small, and is usually defined according to specific application scenarios and needs. The shapes of small-size profiles are diverse, including square tubes, I-beams (smaller in size), angle steels, channel steels, etc., and each shape has its specific application scenarios and advantages. Large-size I-beams are mainly used for the load-bearing part of the structure. The production of large-size I-beams requires more advanced equipment and processes to ensure the accuracy of their dimensions and the smoothness of their surfaces. They are usually made of low-carbon steel and have high bearing capacity and stability. The production of small-size profiles is relatively simple, and a more conventional rolling process can be used. Depending on the specific material and purpose, the performance of small-size profiles will also vary. For example, square tubes usually have good corrosion resistance and impact resistance. When selecting large-size I-beams or small-size profiles, it is necessary to comprehensively consider factors such as specific application scenarios, load requirements, and cost budgets. High-quality materials and advanced production technology can ensure the durability and safety of the profiles.

[0035] The middle layer 22 of the platform structure of the chassis 2 of the embodiment of the present invention is designed to withstand the bending moment of the foundation rotating around the minor axis. This means that when the foundation or equipment rotates in the direction of the minor axis due to external force, the middle layer 22 will play a major supporting and resisting role. In order to withstand such a large bending moment, the middle layer 22 uses large-sized I-beams. Due to its cross-sectional shape, the I-beam has good bending resistance and is an ideal choice for bearing bending moments. Large-sized I-beams are arranged in parallel spacing in the middle layer 22. This arrangement can ensure that the spacing between the I-beams is uniform, so that the force is more uniform, and the overall stability and bearing capacity are improved. The bottom layer 23 is designed to withstand the bending moment of the foundation rotating around the major axis. Unlike the middle layer 22, the bottom layer 23 is mainly subjected to external forces in the direction of the major axis when it is subjected to bending moments. In order to withstand such bending moments, the bottom layer 23 uses small-sized profiles, such as square tubes, I-beams, angle steels, channel steels, etc. Although these profiles are small in size, they can still withstand a certain bending moment under reasonable arrangement and connection methods. Small-size profiles are arranged in parallel and at intervals in the bottom layer 23. This arrangement can ensure that the spacing between the profiles is reasonable, and it will not be too dense to cause material waste, nor too sparse to affect the bearing capacity. At the same time, through reasonable connection methods (such as welding, bolt connection, welding, etc.), the overall stability and bearing capacity of the bottom layer 23 can be ensured. The design scheme of the middle layer 22 and the bottom layer 23 of the platform structure of the box chassis 2 of the embodiment of the present invention fully considers the bending moment in different directions, and achieves the best bearing effect by adopting different materials and arrangement methods. This design scheme not only ensures the stability and bearing capacity of the structure, but also realizes the rational use of materials and cost reduction. In some possible implementations, the bottom layer 23 can also be used to withstand the bending moment of the foundation rotating around the short axis, as the main load-bearing member, and large-size I-beams are arranged in parallel and at intervals; the middle layer 22 is used to withstand the bending moment of the foundation rotating around the long axis, and small-size profiles (square tubes, I-beams, angle steels, channel steels, etc.) are arranged in parallel and at intervals. The same technical effect can be achieved. Of course, in practical applications, further optimization and adjustment are required according to specific engineering requirements and conditions.

[0036] In a possible implementation, the top layer 21 of the platform structure of the chassis 2 of the embodiment of the present invention is made of steel plate or wood, and the surface needs to be flat. When the chassis 2 of the embodiment of the present invention is used as the foundation of the power transmission line repair tower, it is convenient to install and assemble the power transmission line repair tower, and when it is used as the bottom of the storage and transportation box, it is convenient to stack the repair equipment.

[0037] Furthermore, the connection between the middle layer 22 and the bottom layer 23 may be by bolt connection, rivet connection or welding.

[0038] The platform structure of the box chassis 2 can be made of carbon steel, alloy steel, low alloy steel, aluminum alloy and composite materials.

[0039] The embodiment of the present invention also serves as the foundation of the power transmission line repair tower. The equipment quick loading and unloading storage and transportation box adopts a split design for the main frame 1 and the box chassis 2. The main frame 1 is lifted away, leaving the box chassis 2. The repair equipment is directly stacked on the box chassis 2, which is very convenient and efficient. At the same time, the box chassis 2 can also serve as the foundation of the power transmission line repair tower, realizing a unified structure with multiple functions. Because the repair tower foundation is the main load-bearing structure, it is large in size and weight, and it is inconvenient to store and transport. The solution of the embodiment of the present invention makes it unnecessary to process, store and transport it separately, saving material costs and storage and transportation space.

[0040] Another embodiment of the present invention further provides a method for constructing a device rapid loading and unloading storage and transportation box body that also serves as the foundation of a power transmission line repair tower, which specifically includes the following steps: S1. Quickly loading and unloading the equipment that also serves as the foundation of the transmission line repair tower, loading the storage and transportation box onto a truck and transporting it to the work site; S2, at the work site, dismantle the main frame 1 and the chassis 2 of the equipment quick loading and unloading storage and transportation box which also serves as the foundation of the power transmission line repair tower, and take away the main frame 1; S3. Stack the emergency repair equipment on the box chassis 2, use the box chassis 2 also as the foundation of the transmission line emergency repair tower, and directly erect the tower on the box chassis 2.

[0041] In extreme weather conditions, transmission line tower collapse accidents may occur, requiring the urgent allocation of repair materials and the urgent shipment of repair equipment from the reserve base.

[0042] (1) The emergency repair equipment is stored in the warehouse. It is necessary to count the equipment, load it one by one using cranes, forklifts and manual labor, and then unload it one by one from the truck when it arrives at the tower collapse accident site. This is the least efficient and takes the longest time.

[0043] (2) When the emergency repair equipment is stored in a container, use a crane to lift the container onto a flatbed truck and ship it directly. When arriving at the accident site of the tower collapse, lift the container off the flatbed truck, open the container door, and move out the emergency repair equipment piece by piece. There is no loose loading as in (1), and unloading is done on the ground, which is highly efficient. However, due to its large size and weight, the foundation of the emergency repair tower cannot be placed in a conventional container and can only be stored and transported separately.

[0044] (3) The repair tower equipment is stored in the container of the present invention. The crane directly lifts the container onto a flatbed truck for shipment. When the container arrives at the accident site of the collapsed tower, the container is lifted off the flatbed truck, the bolts between the main frame 1 and the chassis 2 are removed, the main frame 1 is lifted away by the crane, and the repair equipment is stacked on the chassis 2. The equipment is completely exposed to the outside, and can be transported and unloaded at all directions at the same time without being restricted by the container body, which significantly improves efficiency. At the same time, the bottom of the container is the base of the repair tower. There is no need for special processing, storage and transportation. The tower can be erected directly on it. The basic material preparation and transportation links are omitted, which is the most efficient.

[0045] In the prior art, the size of the emergency tower foundation may be abnormally large due to design requirements, making it impossible to put it into a standard container for transportation. This increases the difficulty and cost of transportation, and requires finding special transportation methods or custom transportation tools. At the same time, the emergency tower foundation is usually made of high-strength materials to ensure stability and load-bearing capacity. This makes the emergency tower foundation very bulky and difficult to carry and install with conventional loading and unloading equipment. For emergency tower foundations whose sizes exceed those of conventional containers, special transportation tools such as flatbed trucks, low-frame trucks or heavy cranes are used for transportation. These tools have greater loading capacity and stronger adaptability, and can meet the special needs of emergency tower foundation transportation. For oversized emergency tower foundations, they will be designed as detachable or segmented structures so that they can be loaded in sections during transportation. After arriving at the site, they will be reassembled using professional assembly tools and techniques. There are many processes in each link and the operation is inconvenient, which affects the efficiency of emergency repairs.

[0046] The embodiment of the present invention proposes an innovative equipment rapid loading and unloading storage and transportation box design, which is particularly suitable for the basic setting of the power transmission line repair tower and the rapid deployment of equipment. The embodiment of the present invention adopts a split design, and the main frame is designed as a rectangular cover with an opening on the bottom. This design allows easy access to the inside of the box from the bottom, thereby improving the loading and unloading efficiency. The box chassis adopts a platform structure, which not only serves as the bottom support of the storage and transportation box, but also directly serves as the foundation of the power transmission line repair tower, simplifying the repair operation process. The multifunctional box chassis serves as the bottom of the storage and transportation box to ensure the stability and safety of the equipment during transportation. And it directly serves as the foundation of the repair tower, eliminating the steps of separate processing, storage and transportation of the traditional repair tower foundation, thereby reducing costs. After arriving at the work site, the main frame and the box chassis can be quickly disassembled. After the main frame is hoisted away, the repair equipment can be directly stacked on the box chassis, significantly improving the loading and unloading efficiency and construction speed. Compared with the traditional container loading and unloading method through the door or the top, the split design of the embodiment of the present invention allows direct loading and unloading from the bottom, greatly reducing the loading and unloading time and labor costs. The integrated design of the repair tower foundation and the storage and transportation box simplifies the on-site operation process, shortens the repair time, and improves the overall construction efficiency. It eliminates the cost of separate processing, storage and transportation of the repair tower foundation, reduces material costs and transportation costs. It reduces storage space requirements and improves space utilization. The split design allows the chassis and main frame of the box to be used independently, increasing the flexibility of use and is suitable for repair tasks of different scales and types.

[0047] In summary, the equipment quick loading and unloading storage and transportation box that also serves as the foundation of the power transmission line repair tower proposed in the embodiment of the present invention significantly improves the convenience of equipment loading and unloading and construction efficiency through a split design, a multifunctional box chassis, and an efficient loading and unloading method, while also reducing costs and optimizing space utilization. This innovative design is not only suitable for power transmission line repair scenarios, but also provides a useful reference for other fields that require rapid deployment and efficient loading and unloading of equipment.
