Description

Technical Field

[0001] This utility model belongs to the field of automotive engineering technology, and in particular relates to a novel self-loading and unloading load transfer container. Background Technology

[0002] Load transfer modules have many applications. For example, when a section of the main power supply line (mainly composed of 10KV power supply lines and transformers) of a power terminal (residential area, commercial area, etc.) is damaged or malfunctions due to natural disasters (such as typhoons, earthquakes, tsunamis, etc.) or needs to be replaced, the load transfer module can temporarily connect a bypass between the external power supply line and the power terminal, so that the external main power supply line can continue to supply power to the power terminal.

[0003] Currently, common load transfer modular unit (RTM) technologies often employ a simple structure. When an RTM needs to be deployed, rescue units typically need to transport it to the location using transport equipment, and then use hoisting equipment to lift it from the transport equipment to the ground, or use it directly on the transport equipment. Each time a power outage occurs, rescue units often need to temporarily rent mobile cranes and trucks to load, unload, and transport the RTM to the disaster site, making it difficult to guarantee either the speed of rescue or the safety of the RTM. Utility Model Content

[0018] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0020] In this utility model, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0021] like Figures 1-4 As shown, according to one embodiment of the present utility model, a novel self-loading and unloading load transfer container is provided, including a container body 1. The rear of the container body 1 has a maintenance door 11, which allows maintenance personnel to enter the container body 1 to maintain the electrical equipment inside the container body 1 after opening the maintenance door 11. Preferably, the maintenance door 11 provided in this embodiment includes two door panels. The sides of the door panels are hinged to the cabin 1 and rotate to open and close. The two door panels are connected by a lock. The lock can be used to connect and fix the two door panels. When it is necessary to open the maintenance door, the maintenance personnel can open the maintenance door after opening the lock to enter the cabin 1 to perform maintenance work on the electrical equipment.

[0022] Furthermore, such as Figure 1 and Figure 2 As shown in this embodiment of the utility model, a dry-type transformer 3 is also provided inside the cabin 1; the dry-type transformer 3 includes an iron core, windings, a cooling system, an insulation system, and a shell. The iron core is the magnetic circuit part of the dry-type transformer. It is made of stacked silicon steel sheets with high magnetic permeability, which can effectively reduce hysteresis loss and eddy current loss and provide a path for magnetic field conversion. In addition, the windings of the dry-type transformer 3, as the circuit part, are made of copper or aluminum wires and are divided into high-voltage windings and low-voltage windings. The voltage is transformed through electromagnetic induction. The insulation of the windings is achieved by casting or impregnating with insulating materials such as epoxy resin to form an insulating structure, ensuring the insulation performance between the high-voltage and low-voltage windings and between the windings and the iron core. The outer casing of the dry-type transformer 3 mainly serves a protective function, preventing external dust and impurities from entering the transformer. It also reduces operating noise to a certain extent. The casing is also designed with ventilation holes to cooperate with the cooling system. Furthermore, in this embodiment of the present invention, a high-voltage ring main unit 2 is also provided inside the cabin 1. The high-voltage ring main unit 2 has a first high-voltage incoming cabinet 21 and at least two outgoing cabinets. The at least two outgoing cabinets include a first high-voltage outgoing cabinet 22 and a second high-voltage outgoing cabinet 23. In this embodiment, setting multiple outgoing cabinets can realize the power distribution and output to different loads or different directions, thereby improving the power supply reliability and flexibility of the power system.

[0023] Please continue to refer to Figures 1-4 In this embodiment, a low-voltage switch cabinet 4 is also provided inside the cabin 1. The low-voltage switch cabinet 4 includes a low-voltage incoming cabinet 41, a first low-voltage outgoing cabinet 42, and a second low-voltage outgoing cabinet 43. Among them, the low-voltage incoming cabinet 41 serves as the power input hub on the low-voltage side, receiving low-voltage power from the dry-type transformer 3. It controls the on / off of the total power supply through internal switching equipment (such as circuit breakers), playing the role of centralized reception and preliminary control of low-voltage power. The first low-voltage outgoing cabinet 42 and the second low-voltage outgoing cabinet 43 serve as branch nodes for power output, which can be connected to different electrical equipment or circuits in the cabin (for example, one group connects to the control system and lighting equipment, and the other group connects to the power equipment or emergency loads), realizing independent power supply and control for different loads, avoiding chaotic power distribution, and facilitating the quick location and management of each circuit by operation and maintenance personnel. The setup of multiple outgoing line cabinets forms a branch power supply mode. When a circuit connected to one of the outgoing line cabinets fails (such as a short circuit or overload), the faulty circuit can be quickly disconnected by the protection device (such as a fuse or circuit breaker) inside the outgoing line cabinet, preventing the fault from spreading to the entire low-voltage system and ensuring the normal power supply to other circuits. At the same time, this structure can flexibly adapt to different power demand changes in the cabin. If additional power equipment is needed in the future, it can be achieved by expanding the outgoing cabinet or using the spare circuits of the existing outgoing cabinet, without having to make major changes to the core structure of the entire low-voltage switchgear. Please continue to refer to Figures 1-6 In this embodiment, a chassis 6 is provided at the bottom of the cabin 1. Specifically, the cabin 1 is fixedly installed on the chassis 6 through a detachable structure, so that the chassis 6 and the cabin 1 of the load transfer container adopt a 1-to-N mode, that is, one chassis 6 can continuously transport different load transfer containers in sequence, which reduces the cost of the conventional load transfer container requiring a one-to-one configuration of chassis. In one implementation, the detachable structure is connected by bolts. Specifically, multiple connecting lugs are spaced circumferentially along the bottom edge of the cabin 1, and are welded and fixed to the steel frame at the bottom of the cabin 1. Each connecting lug has a circular through hole in the center, and the inner wall of the through hole is smoothed to reduce friction when the bolt is inserted. The upper surface of the chassis 6 is also welded with the same number and specifications of support plates corresponding to the connecting lugs at the bottom of the cabin 1. The center of each support plate has a threaded hole with the same diameter as the through hole of the connecting lug. The bolts used for connection are high-strength hexagonal head bolts, and the matching nuts are hexagonal nuts. During assembly, the cabin 1 is hoisted above the chassis 6, so that the through hole of each connecting lug is coaxially aligned with the threaded hole of the corresponding support plate. Then, the bolt is inserted through the through hole of the connecting lug to complete the fixation of a single connection point. All connection points are operated in this way to finally achieve a rigid connection between the cabin 1 and the chassis 6. During disassembly, simply use a torque wrench to loosen the bolts in the reverse direction, and then remove the bolts, flat washers, and spring washers in sequence to separate the cabin 1 from the chassis 6. The operation is convenient and will not damage the structure of the cabin 1 and chassis 6, meeting the needs of quick cabin replacement in the 1-to-N mode.

[0024] Furthermore, such as Figures 4-6 As shown, in this embodiment, the side of the chassis 6 is provided with an adjustable lateral hydraulic support leg 61. The hydraulic support leg 61 is a hydraulically driven telescopic structure. The bottom end of the hydraulic support leg 61 is provided with a foot. When the self-loading and unloading load transfer cabin is in use, the foot rests on the ground through the support of the hydraulic support leg 61, so that the cabin 1 is suspended in the air, which is convenient for use.

[0025] Furthermore, in this embodiment, to achieve lateral position adjustment of the hydraulic support leg 61, the top end of the hydraulic support leg 61 is connected to the crossbeam. The lateral position of the crossbeam relative to the chassis 6 is adjusted by the lateral adjustment hydraulic rod 62. One end of the lateral adjustment hydraulic rod 62 is connected to the chassis 6, and the other end of the lateral adjustment hydraulic rod 62 is connected to the crossbeam. By extending the lateral adjustment hydraulic rod 62, the crossbeam is pushed to move, causing the hydraulic support leg 61 to extend from the position of the chassis 6. The hydraulic support leg 61 then supports the cabin 1, so that the cabin 1 stands on the ground, thus completing the fixation of the cabin 1.

[0026] Furthermore, such as Figure 3 As shown, a hydraulic oil tank 7 is provided inside the cabin 1 to provide power to the layout that requires hydraulic drive in this embodiment, such as providing power to the hydraulic support leg 61 and the lateral adjustment hydraulic rod 62.

[0027] Furthermore, such as Figure 5 and Figure 6 As shown, the novel self-loading and unloading load transfer container of this embodiment also includes a transport vehicle 5. The bottom of the transport vehicle 5 is equipped with wheels 51. The transport vehicle 5 is used to transfer the container 1. The chassis 6 placed on the transport vehicle 5 is fixed by a bolt and nut mating structure. When transporting the container, the extension function of the hydraulic support legs 61 is first used to make multiple hydraulic support legs 61 extend synchronously, so that the container 1 and chassis 6 are lifted upward as a whole, until the body of the transport vehicle 5 can be moved directly under the container 1 and chassis 6. Then, the multiple hydraulic support legs 61 are shortened synchronously, so that the container 1 and chassis 6 are fixed on the transport vehicle. The hydraulic support legs 61 are further shortened so that the outriggers are off the ground. Then, the extension and retraction function of the lateral adjustment hydraulic rod 62 is used to make the hydraulic support legs 61 retract onto the transport vehicle for convenient transportation.

[0028] Compared with the prior art, the matching method of the chassis 6 and the load transfer container of this utility model adopts the 1-to-N mode, that is, one chassis can continuously transport different load transfer containers in sequence, which reduces the cost of the conventional load transfer container requiring a one-to-one configuration of chassis; the self-loading and unloading container of this utility model has a self-loading and unloading function, thereby reducing the negative impacts such as long waiting time and great safety hazards caused by temporarily renting hoisting equipment.

[0029] The above solutions are merely illustrative examples of preferred embodiments, but are not limited thereto. When implementing this invention, appropriate substitutions and / or modifications can be made according to the user's needs.

[0031] Although embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. It can be applied to various fields suitable for this utility model. Other modifications can be readily implemented by those skilled in the art. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and examples shown and described herein.
