Description

Technical Field

[0001] This application relates to the technical field of goods transfer, and particularly to a pallet. Background Art

[0002] A pallet is a platform used for transporting, storing, or handling items. A mating groove is provided on the pallet. Usually, the fork teeth of industrial tools such as forklifts are inserted into the mating groove to drive the pallet to move, thereby achieving convenient transfer and transportation of items.

[0003] Generally, the surface of the pallet should be kept horizontal to maintain the stability of the items and avoid sliding or displacement of the items during the transfer process. The fork teeth of the forklift are on the same horizontal plane. The pallet can only be kept horizontal when the forklift is working on flat ground. In some application scenarios, such as when the ground has a certain inclination angle, it is difficult to keep the pallet stable. Summary of the Utility Model

[0004] This application provides a pallet and a shelf, which can adjust the levelness of the pallet according to different usage scenarios, ensure the stability of the transported items, and improve the application flexibility.

[0005] In a first aspect, an embodiment of this application provides a pallet having intersecting first and second directions. The pallet includes:

[0006] A body having a bearing surface perpendicular to the first direction. A mating groove is also provided on the body, and the mating groove extends along the second direction;

[0007] An adjusting member, one end of the adjusting member in the first direction is a target end. The target end extends through the bearing surface in the first direction and into the mating groove. The distance between the target end and the bearing surface in the first direction is adjustable.

[0008] To implement the above technical solution, if the application scenario changes, for example, when the application site is inclined, it will cause the fork teeth of the forklift to tilt along with the vehicle body. Since the fork teeth of the forklift are in planar contact with the inner wall surface of the mating groove, the pallet will also tilt. However, with the solution of the embodiment of this application, the target end of the adjusting member can extend into the mating groove and abut against the surface of the fork teeth. Since the distance between the target end and the bearing surface is adjustable, the distance between the position of the fork teeth corresponding to the target end and the bearing surface is adjustable. Furthermore, the fork teeth can be inserted into the mating groove in a posture inclined with respect to the bearing surface, so that the fork teeth and the bearing surface form a certain inclination angle. In this way, even if the fork teeth are in an inclined state, the target end of the adjusting member can abut against the bearing surface to compensate for the inclination angle of the bearing surface, thereby adjusting the bearing surface to maintain a horizontal state better to better meet the usage requirements, improving the stability of item transfer and the flexibility of pallet use.

[0009] As an alternative embodiment of the solution of the present application, the tray has a third direction, the first direction, the second direction and the third direction intersect pairwise, at least two engaging grooves are arranged at intervals along the third direction, and at least one adjusting member is correspondingly arranged for each engaging groove.

[0010] To implement the above technical solution, at least two adjusting members are arranged at intervals along the third direction. When the fork teeth are inclined in the third direction, by adjusting the target ends of the two adjusting members arranged at intervals in the third direction, the depth of the target ends extending into the engaging grooves is adjusted, so as to adjust the distance between different positions of the fork teeth in the third direction and the bearing surface, thereby adjusting the bearing surface to be in a horizontal state when the fork teeth are in an inclined state, ensuring the stability of the tray and improving the applicable scenarios.

[0011] As an alternative embodiment of the solution of the present application, at least two adjusting members are correspondingly arranged for each engaging groove, and a plurality of adjusting members located on the same engaging groove are arranged at intervals along the second direction.

[0012] To implement the above technical solution, when the fork teeth are inclined in the second direction, by adjusting the two adjusting members arranged at intervals along the second direction, the depth of the corresponding target ends of the adjusting members extending into the engaging grooves is adjusted, so as to adjust the distance between different positions of the fork teeth in the second direction and the bearing surface, thereby adjusting the bearing surface to be in a horizontal state, ensuring the stability of the tray and improving the applicable scenarios.

[0013] As an alternative embodiment of the solution of the present application, each adjusting member includes a fixing nut fixed on the bearing surface and an adjusting bolt cooperating with the fixing nut, and the end of the adjusting bolt extending into the engaging groove is the target end.

[0014] To implement the above technical solution, a specific structure of the adjusting member is proposed. When processing the tray, the fixing nut is fixedly welded on the bearing surface, and then the adjusting bolt can be installed. The overall structure is simple and reliable, the processing is convenient, and the fixing nut can improve the stability of the adjusting bolt connected to the body, improving the overall reliability of the tray in use.

[0015] As an alternative embodiment of the solution of the present application, the tray has a third direction, the first direction, the second direction and the third direction intersect pairwise, the body includes a longitudinal beam extending along the second direction and a cross beam extending along the third direction, a plurality of cross beams are arranged at intervals along the second direction, a plurality of longitudinal beams are arranged along the third direction, the cross beams are stacked on the longitudinal beams along the first direction, and the engaging grooves are arranged on the longitudinal beams;

[0016] Wherein, the cross beam has a first surface perpendicular to the first direction, the longitudinal beam has a second surface perpendicular to the first direction, there is a distance between the first surface and the second surface in the first direction to form an avoidance space, and the first surface and the second surface form the bearing surface.

[0017] Implementing the above technical solution, when an item is placed on the first surface and covers the avoidance space, the avoidance space can be used for the insertion of the fork teeth to take out the item, eliminating the need for manual dragging and taking out, so as to improve the operation convenience.

[0018] As an optional embodiment of the solution of the present application, a fitting groove is recessed along the first direction on the surface of the cross beam close to the longitudinal beam, and the longitudinal beam is correspondingly clamped in the fitting groove.

[0019] Implementing the above technical solution, when assembling the tray, the cross beam and the longitudinal beam can be positioned more accurately through the fitting groove, reducing the operation difficulty of the operator; after the cross beam and the longitudinal beam are connected and fixed, the reliability of their connection can be further ensured due to the limitation of the fitting groove.

[0020] As an optional embodiment of the solution of the present application, at least one adjusting member is provided on each longitudinal beam and is located in the avoidance space, and the adjusting member is located on one side of the first surface close to the second surface in the first direction.

[0021] Implementing the above technical solution, the avoidance space can not only be used for the insertion of the fork teeth to pick up and place items, but also for installing the adjusting member, thereby improving the operation flexibility.

[0022] As an optional embodiment of the solution of the present application, a blocking portion is provided at one end of the body in the third direction, and at least a part of the blocking portion is located on one side of the first surface away from the longitudinal beam.

[0023] As an optional embodiment of the solution of the present application, blocking edges are provided on both sides of the body in the third direction, the blocking edges extend along the third direction, and at least a part of the blocking edges is located on one side of the first surface away from the longitudinal beam.

[0024] Implementing the above technical solution, when the item is placed on the tray, it is limited by the blocking edge and the blocking portion in the second direction and the third direction respectively, ensuring the stability of the item when placed on the tray.

[0025] On the other hand, the embodiment of the present application provides a shelf, which includes:

[0026] A plurality of trays as described above, the trays are arranged at intervals along the first direction;

[0027] A base, which is arranged at the bottom of the shelf to support the shelf;

[0028] Connecting beams, which are arranged between the trays adjacent in the first direction, and each connecting beam is respectively connected to two adjacent trays in the first direction.

[0029] As an optional embodiment of the solution of the present application, the connecting beam and the tray are detachably connected.

[0030] One of the technical solutions in the above technical solutions has the following advantages or beneficial effects:

[0031] If the application scenario changes, for example, when the application site is inclined, the fork teeth of the forklift will follow the inclination of the vehicle body. Since the inner wall surface of the fork teeth of the forklift and the mating groove is in planar contact, the pallet will also be inclined. By adopting the solution of the embodiment of the present application, the length of the adjusting member extending into the mating groove can be adjusted by rotating the adjusting member, so that the fork teeth can be inserted into the mating groove in an inclined posture relative to the mating groove, and then the fork teeth and the bearing surface form a certain inclination angle. In this way, even if the fork teeth are in an inclined state, the inclination angle of the bearing surface can be compensated by rotating the adjusting member, so as to adjust the bearing surface to maintain a horizontal state better to better meet the use requirements, reduce the displacement of the articles on the bearing surface, and improve the stability of the article transfer and the flexibility of the pallet use.

[0049] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0050] In the description of the present application, it should be noted that unless otherwise clearly defined and limited, the term "and / or" in this article is only a relationship describing associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this article generally represents an "or" relationship between the associated objects before and after without special explanation.

[0051] Figure 1It is a pallet in the existing related technology. The pallet has a mating groove 2 and a bearing surface 10 for carrying items. The transfer tool drives the transfer of the pallet and the items on the pallet through the mating with the mating groove 2. The transfer tool is generally a forklift. When in use, the fork teeth 1a of the forklift are inserted into the mating groove 2, and the fork teeth 1a are in planar contact with the inner wall surface of the mating groove 2. In a state where the ground M is approximately horizontal, the insertion and mating of the fork teeth 1a and the mating groove 2 keep the bearing surface 10 in a horizontal state. However, if the application scenario changes, for example, when the ground M is inclined, it will cause the fork teeth 1a of the forklift to tilt following the vehicle body. Since the fork teeth 1a of the forklift are in planar contact with the inner wall surface of the mating groove 2, the pallet will also tilt, which is not conducive to the stable transportation of items.

[0052] The main purpose of this application is to design a pallet so that the pallet can adjust its own levelness without changing the structure of the fork teeth 1a, thereby maintaining the stability of item transportation well in different usage scenarios and improving the flexibility of pallet application.

[0053] The following Figures 2 - 10 will give a further detailed introduction to this application.

[0054] Referring to Figure 2 , an embodiment of this application provides a pallet having intersecting first direction Z, second direction X, and third direction Y. The pallet includes a body 1, a mating groove 2, and an adjusting member 3 respectively provided on the body 1. The body 1 has a bearing surface 10 perpendicular to the first direction Z for carrying items. The mating groove 2 is provided on the body 1 and the mating groove 2 extends along the second direction X. One end of the adjusting member 3 in the first direction Z is a target end 3a, and the target end 3a extends through the bearing surface 10 in the first direction Z into the mating groove 2. Among them, the distance between the target end 3a and the bearing surface 10 in the first direction Z is adjustable.

[0055] In the related existing technology, if the application scenario changes, for example, when the application site is inclined, it will cause the fork teeth 1a of the forklift to tilt following the vehicle body. Since the fork teeth 1a of the forklift are in planar contact with the inner wall surface of the mating groove 2, the pallet will also tilt.

[0056] And adopting the solution of the embodiment of this application, for example Figure 3 and Figure 4As shown, the target end 3a of the adjusting member 3 can extend into the mating groove 2 and abut against the surface of the fork tooth 1a. Since the distance between the target end 3a and the bearing surface 10 is adjustable, the distance between the position of the fork tooth 1a corresponding to the target end 3a and the bearing surface 10 is adjustable, enabling the fork tooth 1a to be inserted into the mating groove 2 in a posture inclined with respect to the bearing surface 10. Consequently, the fork tooth 1a forms a certain inclination angle with the bearing surface 10. Therefore, even when the fork tooth 1a is in an inclined state, by using the target end 3a of the adjusting member 3 to abut against the bearing surface 10, the inclination angle of the bearing surface 10 can be compensated and adjusted, thereby adjusting the bearing surface 10 to better maintain a horizontal state to better meet the usage requirements, reducing the displacement of the article on the bearing surface 10, and improving the stability of article transfer and the flexibility of tray use.

[0057] Specifically, for example Figure 3 In, at least two adjusting members 3 are correspondingly provided for each mating groove 2, and the multiple adjusting members 3 located on the same mating groove 2 are arranged at intervals along the second direction X. It can be understood that the interval arrangement means that there is a distance between two adjacent adjusting members 3 along the second direction X on the same mating groove 2. This enables the horizontal degree of the bearing surface 10 to be adjusted by adjusting the two adjusting members 3 along the second direction X when the ground M is inclined along the second direction X, thereby maintaining the stability of the article.

[0058] Similarly, for example Figure 4 In, at least two mating grooves 2 are arranged at intervals along the third direction Y, and at least one adjusting member 3 is correspondingly provided for each mating groove 2. It can be understood that the interval arrangement means that there is a distance between two adjacent mating grooves 2 along the second direction X on the body 1. This enables the horizontal degree of the bearing surface 10 to be adjusted by adjusting the two adjusting members 3 along the third direction Y when the ground M is inclined along the third direction Y, thereby maintaining the stability of the article.

[0059] It should be noted that in Figure 3 and Figure 4 both, two adjusting members 3 are set to cooperate with each other to adjust the inclination angle of the fork tooth 1a relative to the mating groove 2. However, it can be understood that the number of adjusting members 3 is not limited to two, and the technical effect of adjusting the horizontal degree of the bearing surface can be achieved by providing more than two adjusting members 3 or only through one adjusting member 3. For example Figure 3 In, the adjusting member 3 on the right is cancelled, and the corresponding function can still be achieved only through the adjusting member 3 on the left.

[0060] Continue to refer to Figure 2, in an alternative embodiment, the body 1 includes a longitudinal beam 11 extending along a second direction X and a cross beam 12 extending along a third direction Y. A plurality of cross beams 12 are provided at intervals along the second direction X, and a plurality of longitudinal beams 11 are provided along the third direction Y. The cross beams 12 are stacked on the longitudinal beams 11 along the first direction Z, and the mating groove 2 is provided on the longitudinal beam 11; wherein, the cross beam 12 has a first surface 121 perpendicular to the first direction Z, and the longitudinal beam 11 has a second surface 111 perpendicular to the first direction Z. The first surface 121 and the second surface 111 have a spacing in the first direction Z to form an avoidance space 4, and the first surface 121 and the second surface 111 form a bearing surface 10.

[0061] It can be understood that two adjacent cross beams 12 are parallel and have a spacing in the second direction X, and two adjacent longitudinal beams 11 are parallel and have a spacing in the third direction Y.

[0062] When an article is placed on the first surface 121 and covers the avoidance space 4, the fork teeth 1a can be inserted into the avoidance space 4, and the article can be taken out by using the fork teeth 1a. Compared with the existing tray in which the entire bearing surface 10 is a unified horizontal plane, the tray provided in this application can effectively improve the convenience of using the tray.

[0063] Refer to Figure 2 , in an example, more specifically for the body 1, two longitudinal beams 11 are provided at intervals along the third direction Y, and the two longitudinal beams 11 are parallel to each other. Two cross beams 12 are provided at intervals along the second direction X, and the two cross beams 12 are parallel to each other. Both the cross beam 12 and the longitudinal beam 11 are hollow square tubes, and the hollow inner cavity of the longitudinal beam 11 forms the above-mentioned mating groove 2. Each cross beam 12 is stacked above the longitudinal beam 11 along the first direction Z, that is, the first surface 121 is higher than the second surface 111 in the first direction Z. One end of each longitudinal beam 11 has a part extending beyond the range covered by the cross beam 12.

[0064] More specifically, a fitting groove 5 is recessed along the first direction Z on the surface of the cross beam 12 close to the longitudinal beam 11, and the longitudinal beam 11 is correspondingly clamped in the fitting groove 5. In an example, after the cross beam 12 and the longitudinal beam 11 are assembled through the fitting groove 5, the two can be fixed by welding.

[0065] In this embodiment, when assembling the tray, the cross beam 12 and the longitudinal beam 11 can be accurately positioned through the fitting groove 5, reducing the operation difficulty of the operator; after the cross beam 12 and the longitudinal beam 11 are connected and fixed, the limit of the fitting groove 5 can further ensure the reliability of the connection between the two.

[0066] The adjusting member 3 will be further explained below.

[0067] Refer to Figure 3 、 Figure 4 andFigure 5 In an optional embodiment, each adjusting member 3 includes a fixing nut 32 fixed on the bearing surface and an adjusting bolt 31 matched with the fixing nut 32, and the end of the adjusting bolt 31 extending into the matching groove 2 is the target end 3a. Specifically, the adjusting bolt 31 is threadedly matched in the fixing nut 32, and a through hole is opened on the longitudinal beam 11 along the first direction Z and penetrates the second surface 111, and the inner wall of the through hole is smooth, so that the target end 3a can extend into the matching groove 2.

[0068] In the conventional technology, it is necessary to machine a threaded hole on the longitudinal beam 11 in order to assemble the adjusting bolt 31. However, the side wall of the longitudinal beam 11 is usually thin, which makes the machined threaded hole shallow, making it difficult to provide the adjusting bolt 31 with stable and reliable connection support, and there is a great process difficulty in machining the threaded hole on the thin wall. Therefore, in the embodiment of the present application, when machining the pallet, it is only necessary to fix and weld the fixing nut 32 on the bearing surface 10, and then the adjusting bolt 31 can be installed using the thread in the fixing nut 32, without machining a threaded hole on the longitudinal beam 11, which makes the overall structure simple and reliable, and the machining is convenient. In addition, the fixing nut 32 can effectively improve the stability of the adjusting bolt 31 connected to the body 1, and improve the overall reliability of the pallet. When operating the adjusting member 3, the adjusting bolt 31 is rotated to adjust the distance between the target end 3a and the bearing surface 1a, so that the target end 3a extends into a predetermined depth, and the use process of the adjusting member 3 is completed.

[0069] It should be noted that the through hole formed on the longitudinal beam 11 and penetrating the second surface 111 along the first direction Z may also be a threaded hole. In this case, there are two ways to assemble the adjusting bolt 31. The first way is that the adjusting bolt 31 is directly threadedly connected to the threaded hole on the longitudinal beam 11 without threading with the fixing nut 32, and the fixing nut 32 only serves to strengthen and limit the outer wall of the adjusting bolt 31. Alternatively, the adjusting bolt 31 is threadedly connected to the fixing nut 32 and the through hole with internal threads at the same time.

[0070] It should be noted that the adjusting member 3 in the embodiment of the present application adopts the above-mentioned adjustment bolt 31 and the fixing nut 32, but it is not excluded that the adjusting member 3 has a different structural form in other optional embodiments. For example, in some examples, refer to Figure 10, the adjusting member 3 includes an adjusting shaft 35 that penetrates the bearing surface 10 along the first direction Z and extends into the fitting groove 2, and a driving member 36 that drives the adjusting shaft 35 to reciprocate along the first direction Z and can be positioned at a certain position. It can be understood that the driving member 36 can be selected according to different situations. In one example, the driving member 36 is a linear module, and the slider of the linear module is fixedly connected to the adjusting shaft 36. At this time, in order to avoid interference of the driving member 36 on the placement of items, two adjusting shafts 36 are selected to be arranged outside the longitudinal beam 11 on the side away from the avoidance space 4 of the two cross beams 12. In some embodiments, the driving member 36 can also be other driving structures such as an electric cylinder.

[0071] In an alternative embodiment, at least two fitting grooves 2 are arranged at intervals along the third direction Y, and at least one adjusting member 3 is correspondingly arranged for each fitting groove 2.

[0072] Wherein, the corresponding arrangement referred to herein means that the target end 3a of the adjusting member 3 penetrates the bearing surface 10 of the fitting groove 2 parallel to the first direction Z and used for bearing items and can extend into the fitting groove 2. It can be understood that specifically Figure 2 as mentioned, the target end 3a of the adjusting member 3 penetrates the second surface 111 along the first direction Z and can extend into the corresponding fitting groove 2.

[0073] Specifically in this embodiment, one fitting groove 2 is correspondingly arranged on each longitudinal beam 11, and the number of fitting grooves 2 is the same as that of the longitudinal beams 11, both being two.

[0074] Refer to Figure 4 , the setting of the embodiment of the present application enables at least two adjusting members 3 to be arranged at intervals along the third direction Y. When the fork teeth 1a are inclined in the third direction Y, by rotating the two adjusting members 3 arranged at intervals in the third direction Y and making the target end 3a abut against the surface of the fork teeth 1a, the distance between different positions of the fork teeth 1a in the third direction Y and the bearing surface 10 can be changed. Thus, when the ground M is inclined and the fork teeth 1a are in an inclined state, the bearing surface 10 can be adjusted by the adjusting member 3 to make the bearing surface 10 in a horizontal state, ensuring the stability of the tray and improving the applicable scenarios.

[0075] In an alternative embodiment, at least two adjusting members 3 are correspondingly arranged for each fitting groove 2, and the adjusting members 3 located on the same fitting groove 2 are arranged at intervals along the second direction X.

[0076] For the above embodiments, when the fork teeth 1a are inclined in the second direction X, by adjusting the two adjusting members 3 arranged at intervals along the second direction X and making the target end 3a abut against the surface of the fork teeth 1a, the distance between different positions of the fork teeth 1a in the second direction X and the bearing surface 10 can be changed, so as to adjust the bearing surface 10 to be in a horizontal state, ensuring the stability of the tray and improving the applicable scenarios.

[0077] As an alternative embodiment of the solution of the present application, each longitudinal beam 11 has at least one adjusting member 3 located in the avoidance space 4, and the adjusting member 3 is located on one side of the first surface 121 close to the second surface 111 in the first direction Z.

[0078] Specifically in this embodiment, two adjusting members 3 are correspondingly arranged on each mating groove 2. One adjusting member 3 is located in the avoidance space 4, and the other adjusting member 3 is located at one end of the longitudinal beam 11 extending beyond the coverage of the cross beam 12 in the second direction X.

[0079] The avoidance space 4 can not only be used for the fork teeth 1a to insert to pick up and place items, eliminating the need for manual dragging and taking out, so as to improve the operation convenience; but also can be used for installing the adjusting member 3, thereby improving the operation flexibility.

[0080] Back to Figure 2 As an alternative embodiment of the solution of the present application, a blocking portion 6 is provided at one end of the main body 1 in the third direction Y, and at least a part of the blocking portion 6 is located on one side of the first surface 121 away from the longitudinal beam 11. Blocking edges 7 are provided on both sides of the main body 1 in the third direction Y, and the blocking edges 7 extend along the third direction Y, and at least a part of the blocking edges 7 is located on one side of the first surface 121 away from the longitudinal beam 11.

[0081] Specifically, a bracket 13 is fixedly connected between the two cross beams 12, and the blocking portion 6 is fixedly arranged on the surface of the bracket 13. When an item is placed on the tray, it is limited by the blocking edge 7 and the blocking portion 6 in the second direction X and the third direction Y respectively, ensuring the stability of the item when placed on the tray.

[0082] Refer to Figure 6 and Figure 7 The embodiment of the present application provides a shelf, which includes: a plurality of trays as described above, the trays are arranged at intervals in the first direction; a base 100, arranged at the bottom of the shelf for supporting the shelf; a connecting beam 200, arranged between the trays adjacent in the first direction, and the connecting beam 200 is respectively connected to two adjacent trays in the first direction Z.

[0083] As an alternative embodiment of the solution of the present application, the connecting beam 200 is detachably connected to the tray.

[0084] Refer to Figure 6 、 Figure 7 and Figure 8 Specifically, four connecting beams 200 are arranged between two trays. Connecting pieces 201 are provided at the top and bottom ends of each connecting beam 200 in the first direction Z. The connecting pieces 201 are parallel to the bearing surface 10. The connecting pieces 201 at the top and bottom ends of the connecting beam 200 are respectively bolted to the cross beams 12 on the top layer and bottom layer trays.

[0085] Refer to Figure 7 , specifically, the base 100 is arranged in a C-shaped frame, and flanges 101 are provided at both ends of the base 100 in the third direction Y. The flanges 101 extend upward along the first direction Z, and the flanges 101 are bolted to the cross beam 12 of the bottom tray.

[0086] In the embodiment of the present application, the trays are detachably connected and can form a multi-layer structure, so as to facilitate the replacement and maintenance of items. In one example, refer to Figure 9 , taking the shelf having two layers of trays and maintaining and replacing the battery pack as an example. The specific replacement steps are as follows:

[0087] In the initial state, a new battery pack 500 to be replaced is placed on the tray at the top of the shelf, and the forklift is used to drive the shelf to move to the side of the container 60;

[0088] Operate the forklift to lift the shelf upward so that the whole shelf moves upward until the tray at the bottom of the shelf is flush with the position to be replaced. At this time, there is an old battery pack 50 at this position; specifically, make the first surface 121 parallel to the bottom surface of the old battery pack 50;

[0089] The operator drags the old battery pack 50 onto the first surface 121, and operates the forklift to lower the whole shelf until the top tray is flush with the position to be replaced. At this time, the old battery pack 50 at this position has been taken out to the bottom tray;

[0090] The operator pushes the new battery pack 500 into the position to be replaced.

[0091] As above, the forklift only needs to be lifted and lowered once to complete the removal of the old battery pack 50 and the installation of the new battery pack 500. Especially at present, the integration degree and energy density of the container 60 are getting higher and higher, and the battery packs in the container 60 are gradually developing in the direction of large size and large weight. Therefore, the pulling, maintenance and replacement of the battery packs are more difficult and it is difficult to complete completely by manpower. For this reason, the trays and shelves provided by the embodiment of the present application can cooperate with the forklift more conveniently and solve the problem of difficult maintenance and replacement of the battery pack more simply and conveniently.

[0092] When the tray needs to be used alone, the tray can be taken out separately. It should be noted that when the tray is used alone, the base 100 can still be installed for support to avoid damage caused by the longitudinal beam 11 directly contacting the ground M.

[0093] As described above, it is only a partial implementation manner of the embodiments of the present application, and does not impose any formal restrictions on the application. The protection scope of the embodiments of the present application is not limited thereto. Any simple modifications, equivalent changes and modifications that can be easily thought of by those skilled in the technical field of the present application within the technical scope disclosed by the embodiments of the present application should be covered within the protection scope of the embodiments of the present application.
