[0035] Before any embodiments of the application are explained in detail, it is to be understood that the application is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the above drawings.

[0036] In this application, the terms "comprises", "includes", "has" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of more restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device that includes the element.

[0037] In the present application, the term "and / or" is a description of the association relationship of associated objects, indicating that three relationships may exist. For example, a centrifugal vortex magnetic pump and / or a centrifugal vortex magnetic pump can represent: the existence of a centrifugal vortex magnetic pump alone, the existence of a centrifugal vortex magnetic pump and a centrifugal vortex magnetic pump at the same time, and the existence of a centrifugal vortex magnetic pump alone. In addition, the character " / " in the present application generally indicates that the objects associated before and after are in an "and / or" relationship.

[0038] In the present application, the terms "connect", "combine", "couple", and "install" may refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, direct connection refers to two parts or components being connected together without the need for an intermediate piece, and indirect connection refers to two parts or components being connected to at least one intermediate piece respectively, and the two parts or components being connected via the intermediate piece. In addition, "connect" and "couple" are not limited to physical or mechanical connections or couplings, and may include electrical connections or couplings.

[0039] In the present application, it will be understood by those of ordinary skill in the art that relative terms (e.g., "about," "approximately," "substantially," etc.) used in conjunction with quantities or conditions include the values ​​and have the meaning indicated by the context. For example, the relative terms include at least the degree of error associated with the measurement of a specific value, the tolerances caused by manufacturing, assembly, and use associated with a specific value, and the like. Such terms should also be considered to disclose a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to plus or minus a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​that do not use relative terms should also be disclosed as specific values ​​with tolerances. In addition, "substantially" may refer to plus or minus a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) on the basis of the indicated angle when expressing a relative angular position relationship (e.g., substantially parallel, substantially perpendicular).

[0040] In this application, it will be understood by those skilled in the art that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0041] In the present application, the terms "upper", "lower", "left", "right", "front", "back" and other directional words are described based on the orientation and positional relationship shown in the accompanying drawings, and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element. It should also be understood that directional words such as upper side, lower side, left side, right side, front side, back side, etc. not only represent the positive orientation, but can also be understood as the lateral orientation. For example, the bottom can include directly below, lower left, lower right, lower front, and lower back, etc.

[0042] See also Figures 1 to 5 This embodiment provides a beam structure for a battery swap station, which is arranged on a frame of a container 100 and is used to carry a battery swap device 200. The beam structure for a battery swap station includes a plurality of first rail steels 1, a plurality of connectors 2, and a plurality of tie rods 3.

[0043] A plurality of first rail steels 1 are arranged in parallel with each other and divided into a plurality of groups of bearing rails 11, each group of bearing rails 11 includes two first rail steels 1, and a guide channel 12 for guiding the rolling of the running wheels of the power exchange device 200 is formed between the two first rail steels 1. A plurality of connecting members 2 are used to connect the two first rail steels 1. A plurality of cross tie rods 3 are arranged between any two adjacent groups of bearing rails 11 to form one or more beams 10 with all the bearing rails 11.

[0044] It is understandable that the first rail steel 1 is a standard profile; it has the following advantages: First, the first rail steel 1 has high strength, high hardness and good wear resistance, and can withstand heavy loads and long span requirements; second, the first rail steel 1 has high straightness and dimensional accuracy, which meets the accuracy requirements of the beam structure; third, the first rail steel 1 is a standard profile that is easy to purchase on the market, and the price is relatively low, which reduces the material cost. In addition, the use of standard profiles can avoid secondary processing, such as cutting and drilling, and reduce processing difficulty and cost. In addition, by using the standard size of standard profiles, the beam structure is manufactured by cutting, assembling, and welding, shortening the manufacturing cycle, that is, simplifying the manufacturing process, reducing processing and labor costs, and standardized and modular design, improving manufacturing and installation efficiency.

[0045] It should be noted that, in this embodiment, the first rail steel 1 is a standard rail steel of 50 kg / m, and the material is U71Mn or 50Mn.

[0046] It can also be understood that the two first rail steels 1 are connected by the connector 2, which increases the section modulus and improves the bending resistance of the bearing rail 11 to meet the requirements of long span and heavy load. In addition, multiple cross-tie rods 3 can connect all the bearing rails 11 into one, and form a box-type section, which improves the torsional rigidity of the beam structure and prevents the beam structure from twisting during operation. The overall stability of the beam structure is improved, ensuring the operating accuracy and safety of the battery exchange equipment 200. The "beam structure" in the previous text refers to the "beam structure for battery exchange stations", and the same is true in the following text.

[0047] Generally speaking, in order to complete the battery replacement, the battery swap device 200 needs to move on the beam. Therefore, by guiding the rolling of the running wheels of the battery swap device 200 through the guide channel 12 formed between the two first rail steels 1, the battery swap device 200 can move more smoothly. Specifically, each first rail steel 1 has a guide rail that cooperates with the running wheel, and the running channel 52 is composed of two guide rails of the two first rail steels 1, and the two guide rails cooperate with the opposite sides of the running wheel respectively.

[0048] It is worth noting that the battery exchange device 200 usually has two sets of running wheels distributed on both sides thereof. Correspondingly, the two sets of bearing rails 11 are combined into a beam 10. The two guide channels 12 in the same beam 10 are used to respectively guide the running wheels on both sides of the same battery exchange device 200. It should be noted that the number of beams 10 can be designed according to the actual application scenario. In this embodiment, the beam 10 is set to one.

[0049] In order to further enhance the structural strength of the beam structure, multiple reinforcing members 4 are distributed on the opposite sides of the two groups of bearing rails 11 in the same beam 10 to connect the two first rail steels 1 and the connecting member 2 in the same group of bearing rails 11. Such an arrangement can further improve the overall rigidity and torsional resistance of the beam structure.

[0050] Specifically, the reinforcement member 4 is in a "C" shape, and a snap-in groove 41 is formed in the middle, the connector 2 is partially embedded in the snap-in groove 41, and the two sides of the reinforcement member 4 are respectively connected to the two first rail steels 1. It should be pointed out that the multiple cross-tie rods 3 mentioned above can also be connected to the reinforcement member 4 at the corresponding position. It should also be pointed out that the first rail steel 1, the connector 2, the reinforcement member 4 and the cross-tie rod 3 are connected by welding to improve the connection strength. In particular, the connector 2 can be selected as a connecting plate or a channel steel for easy assembly.

[0051] In the prior art, many battery exchange devices 200 include a hoist for lifting the battery pack, and the hoist generally needs to extend out of the container 100 to lift the battery pack on the electric mining truck. To this end, in this embodiment, the beam structure for the battery exchange station also includes a main beam 20 with two sets of rollers (not shown in the figure), and the main beam 20 can be slidably arranged in the beam 10 through the two sets of rollers, and the main beam 20 is used to carry the battery exchange device 200. In this way, the main beam 20 can partially extend out of the beam 10 to drive the battery exchange device 200 to extend out of the container 100, thereby meeting the needs of the battery exchange device 200 to lift the battery pack on the electric mining truck.

[0052] Specifically, the main beam 20 also includes four second rail steels 5 and a plurality of adapters 6. The four second rail steels 5 are distributed in a rectangular shape and are arranged parallel to each other. The plurality of adapters 6 are distributed around the four second rail steels 5 to connect the four second rail steels 5 into one body to form a receiving cavity 51 for receiving the battery exchange device 200.

[0053] It is understandable that the second rail steel 5 is a standard material, which reduces the use of customized profiles. The material is easy to obtain and inexpensive, and the manufacturing process is simplified, reducing processing and labor costs. It is also understandable that multiple adapters 6 are distributed around the four second rail steels 5 to connect the four second rail steels 5 into one, forming an open or semi-closed cross-section, which is convenient for the power exchange equipment 200 to operate inside. In addition, it can also improve the torsion resistance and overall stability, and prevent deformation and instability. Of course, the optimization of the cross-sectional size also reduces the deadweight of the main beam 20 and reduces the load on the drive structure that drives its movement.

[0054] In addition, the main beam 20 and beam 10 also use standard profiles and modular design, which is convenient for cutting, assembly and welding, and has a simple structure and a small number of components, which reduces the difficulty and time of installation. The main beam 20 and beam 10 have slightly different functional focuses. Beam 10 mainly focuses on bearing and supporting the entire equipment, which requires high bearing capacity and high rigidity. The main beam 20 focuses on realizing the telescopic function and the operation of the battery replacement equipment, and must take into account both lightweight and spatial adaptability. Preferably, the cross-sectional size of beam 10 is larger, and a closed box-type section is adopted to enhance the bending and torsion resistance. The cross-sectional size of the main beam 20 is smaller, and an open section is adopted to adapt to spaces with limited height and width.

[0055] It should be noted that, in this embodiment, the thickness of the main beam 20 is designed to be about 300 mm, which is suitable for spaces with limited height. It should also be noted that, through mechanical calculation and optimized design, the deflection and stress of the main beam 20 meet the use requirements when the extended length reaches 5 meters and the load is 10 tons.

[0056] In order to facilitate the movement of the battery exchange device 200 in the main beam 20, the four second rail steels 5 are divided into two groups of running rails, and a walking channel 52 is formed between the two second rail steels 5 in each group of running rails to guide the rolling of the running wheels of the battery exchange device 200. It should be noted that the structure of the walking channel 52 is consistent with the structure of the guide channel 12 mentioned above, so it will not be repeated.

[0057] This embodiment further provides a beam structure for a battery swap station, including a container 100, a battery swap device 200, and the above-mentioned beam structure for a battery swap station, wherein the beam structure for a battery swap station is arranged on the frame of the container 100, and the beam structure for a battery swap station is used to carry the battery swap device 200. It can be understood that the manufacturing and installation costs of the battery swap station including the above-mentioned beam structure for a power station are low, thereby reducing the initial investment pressure of the enterprise and increasing its enthusiasm for the application of electric mining trucks.

[0058] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention.
