Detailed Implementation

[0040] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0041] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0042] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0043] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0044] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0045] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0046] Figure 1 A schematic diagram of the structure of a transfer device provided in an embodiment of this application is shown.

[0047] See Figure 1As shown, this application embodiment provides a transfer device 10 for transferring a component (not shown), including a base 11, a first lifting mechanism 12, and a second lifting mechanism 13. The base 11 is connected to one side of the component to be transferred. The first lifting mechanism 12 includes a first lifting component 121 and a first traveling component 122. The first lifting component 121 is connected to the base 11, and the first traveling component 122 is connected to the first lifting component 121. The second lifting mechanism 13 includes a second lifting component 131 and a second traveling component 132. The second lifting component 131 is disposed opposite to the first lifting component 121 and connected to the base 11. The second lifting component 131 and the first lifting component 121 cooperate to lift the base 11. The second traveling component 132 is connected to the second lifting component 131.

[0048] The transfer device 10 provided in this application embodiment includes a base 11, a first lifting mechanism 12, and a second lifting mechanism 13. The first lifting mechanism 12 includes a first lifting component 121 and a first traveling component 122. The second lifting mechanism 13 includes a second lifting component 131 and a second traveling component 132. The base 11 is used to connect to one side of the part to be transferred. The first lifting component 121 is connected to the base 11. The second lifting component 131 is disposed opposite to the first lifting component 121 and connected to the base 11. The first traveling component 122 is connected to the first lifting component 121, and the second traveling component 132 is connected to the second lifting component 131. The second lifting component 131 and the first lifting component 121 cooperate to lift the base 11, thereby raising one side of the part to be transferred. Thus, when transferring a component, two transfer devices 10 can be positioned opposite each other on both sides of the component, with two bases 11 connected to both sides of the component. The first lifting component 121 and the second lifting component 131 of each transfer device 10 cooperate to lift the corresponding base 11, thereby lifting the entire component. The two first walking components 122 and the two second walking components 132 of the two transfer devices 10 then carry the entire component, thus achieving the transfer. This transfer device 10 uses the base 11, the first lifting component 121, and the second lifting component 131 to fix and lift the component, and uses the first walking components 122 and the second walking components 132 to transfer the component. It requires no additional equipment, is convenient to use, and is simple and quick to operate, enabling rapid transfer of components and improving transfer efficiency.

[0049] It should be noted that the item to be transferred can be an inflatable cabinet, which includes a floor-mounted cabinet body. When transferring the inflatable cabinet, two transfer devices 10 are positioned opposite each other on both sides of the inflatable cabinet, with two bases 11 respectively connected to both sides of the cabinet body. The first lifting component 121 and the second lifting component 131 of each transfer device 10 cooperate to lift the corresponding base 11, thereby lifting the entire inflatable cabinet off the ground. The two first walking components 122 and the two second walking components 132 of the two transfer devices 10 are distributed at the four corners of the bottom of the inflatable cabinet. These components carry the entire inflatable cabinet, thus achieving the transfer of the item to be transferred. Of course, the item to be transferred can also be other workpieces. This application does not impose any special restrictions on this.

[0050] In one embodiment, see [reference] Figure 2 As shown, the base 11 includes a support arm 111 and a plurality of first connectors 112. The support arm 111 is hollow inside. A first lifting assembly 121 and a second lifting assembly 131 are respectively disposed at both ends of the support arm 111 and are both connected to the support arm 111. The second lifting assembly 131 and the first lifting assembly 121 cooperate to lift the support arm 111. The plurality of first connectors 112 are located on the same side of the support arm 111 and are spaced apart on the support arm 111. The plurality of first connectors 112 are used to connect with the item to be transferred.

[0051] Therefore, by including a support arm 111 and a plurality of first connectors 112 in the base 11, the connection between the base 11 and the object to be transferred can be facilitated, improving the reliability of the connection between the base 11 and the object to be transferred, while also facilitating the connection between the base 11 and the first lifting assembly 121 and the second lifting assembly 131, so as to lift the object to be transferred.

[0052] Understandably, the base 11 may include two first connectors 112, which are located on the same side of the support arm 111 and are spaced apart on the support arm 111.

[0053] In one embodiment, see [reference] Figure 2 As shown, the first connector 112 includes a first connecting part 1121 and a first supporting part 1122. The first connecting part 1121 is fixedly connected to the supporting arm 111. The first connecting part 1121 is provided with a plurality of mounting holes 1121a at intervals. The mounting holes 1121a are used to connect with the part to be transferred by means of fasteners. The first supporting part 1122 protrudes from the side of the first connecting part 1121 away from the supporting arm 111. The first supporting part 1122 is used to pass through the part to be transferred.

[0054] Therefore, by providing multiple mounting holes 1121a at intervals on the first connecting part 1121, the first connecting part 1121 can be easily connected to the part to be transferred using fasteners. By protruding the first support part 1122 on the side of the first connecting part 1121 away from the support arm 111, the first support part 1122 can be inserted into the part to be transferred. In this way, the part to be transferred can be lifted or lowered synchronously with the base 11, thereby realizing the rapid transfer of the part to be transferred and improving the transfer efficiency.

[0055] It should be noted that the component to be transferred may be provided with a connecting hole (not shown) that mates with the mounting hole 1121a. For example, a connecting hole may be provided on the side wall of the gas-insulated cabinet, and fasteners may pass through the mounting hole 1121a and the connecting hole to fix the first connecting part 1121 to the side wall of the gas-insulated cabinet. The fasteners may be rivets, bolts, etc. The component to be transferred may be provided with a through hole (not shown) through which the first support part 1122 passes, so that the first support part 1122 passes through the component to be transferred.

[0056] In one embodiment, see [reference] Figure 3 and Figure 4 As shown, both the first lifting assembly 121 and the second lifting assembly 131 include a lifting lever 14 and a driving member 15. One end of the lifting lever 14 extends into the support arm 111 and is rotatably connected to the support arm 111. The other end of the lifting lever 14 is located outside the support arm 111 and is connected to the first traveling assembly 122 or the second traveling assembly 132. The driving member 15 is located at one end of the support arm 111 near the first traveling assembly 122 or the second traveling assembly 132. The driving member 15 is used to apply downward pressure to the lifting lever 14 so that the end of the lifting lever 14 connected to the support arm 111 is lifted upward and held in the lifted position.

[0057] Therefore, by positioning the other end of the lifting lever 14 outside the support arm 111 and connecting the other end of the lifting lever 14 to the first traveling assembly 122 or the second traveling assembly 132, when the first lifting assembly 121 and the second lifting assembly 131 are in their initial positions, i.e., when the driving member 15 applies force to the lifting lever 14, due to the certain height of the first traveling assembly 122 or the second traveling assembly 132 and the certain weight of the support arm 111, under the supporting action of the first traveling assembly 122 or the second traveling assembly 132 and the gravity of the support arm 111, the end of the lifting lever 14 connected to the support arm 111 can be lower than the other end of the lifting lever 14 connected to the first traveling assembly 122 or the second traveling assembly 132, and the lifting lever 14 abuts against the side wall of the support arm 111 near the driving member 15. When it is necessary to lift the support arm 111, the drive member 15 applies downward pressure to the lifting lever 14. Since the drive member 15 is located at one end of the support arm 111 near the first travel assembly 122 or the second travel assembly 132, the drive member 15 applies downward pressure at the position of the lifting lever 14 near the first travel assembly 122 or the second travel assembly 132, thereby allowing the end of the lifting lever 14 connected to the support arm 111 to be lifted upward and held in the lifted position. The lifting lever 14 can abut against the side wall of the support arm 111 away from the drive member 15 to lift the support arm 111, and then lift the item to be transferred. In addition, the driving component 15 applies downward pressure to the lifting lever 14, causing the end of the lifting lever 14 connected to the support arm 111 to be raised and held in the raised position. The lifting height of the end of the lifting lever 14 connected to the support arm 111 is relatively small, so that the entire item to be transferred is raised to a relatively small height, which can reduce the risk of the item to be transferred (especially the gas cabinet with a large height-to-width ratio) tipping over during the transfer process.

[0058] In one embodiment, see [reference] Figure 3 As shown, the driving component 15 includes a guide 151, a telescopic rod 152, and a driving sub-component 153. The guide 151 is fixed to the support arm 111, and a guide channel 151a is provided on the guide 151. The telescopic rod 152 is movably inserted into the guide channel 151a, and one end of the telescopic rod 152 away from the support arm 111 extends out of the guide 151. A through hole 111a communicating with the guide channel 151a is provided on the support arm 111. The driving sub-component 153 is connected to the telescopic rod 152 and the guide 151. The driving sub-component 153 is used to drive the telescopic rod 152 to move along the axial direction of the guide channel 151a, so that the telescopic rod 152 can pass through the through hole 111a and abut against the lifting lever 14, and apply downward pressure to the lifting lever 14, so that the end of the lifting lever 14 connected to the support arm 111 is lifted upward and held in the lifted position.

[0059] Therefore, when it is necessary to lift the support arm 111 for the transfer of the item to be transferred, the drive sub-unit 153 drives the telescopic rod 152 to move along the guide channel 151a toward the lifting lever 14, so that the telescopic rod 152 passes through the through hole and abuts against the lifting lever 14, applying downward pressure to the lifting lever 14, causing the end of the lifting lever 14 connected to the support arm 111 to rise and remain in the raised position, thereby lifting the support arm 111, and thus lifting the item to be transferred for its transfer. When the transfer of the item is completed and it is necessary to put it down, the drive sub-unit 153 drives the telescopic rod 152 to move along the guide channel 151a away from the lifting lever 14, so that the telescopic rod 152 moves away from the lifting lever 14, and the end of the lifting lever 14 connected to the support arm 111 moves downward under the gravity of the item to be transferred, thereby putting the item down.

[0060] In one embodiment, see [reference] Figure 4 As shown, the drive sub-unit 153 includes a second connector 1531, a third connector 1532, and a pressure rod 1533; one end of the second connector 1531 is rotatably connected to the guide member 151; one end of the third connector 1532 is rotatably connected to the end of the telescopic rod 152 away from the support arm 111; the other end of the third connector 1532 is rotatably connected to the other end of the second connector 1531; one end of the pressure rod 1533 is connected to the third connector 1532, and the other end of the pressure rod 1533 extends in a direction away from the third connector 1532.

[0061] Therefore, by lifting or pressing down the pressure rod 1533, the telescopic rod 152 can be driven to move along the axial direction of the guide channel 151a, so that the telescopic rod 152 abuts against or moves away from the lifting lever 14, thereby realizing the lifting or lowering of the support arm 111. The operation is convenient and easy, and the rapid transfer of the parts to be transferred can be realized, improving the transfer efficiency of the parts to be transferred.

[0062] In one embodiment, see [reference] Figure 4 As shown, the second connecting member 1531 includes a first bottom wall 1531a and two first side walls 1531b perpendicularly connected to both sides of the first bottom wall 1531a; the two first side walls 1531b are rotatably connected to the end of the guide member 151 away from the support arm 111 via a first rotating member 16; the third connecting member 1532 includes a second bottom wall 1532a and two second side walls 1532b perpendicularly connected to both sides of the second bottom wall 1532a; the two second side walls 1532b are rotatably connected to the end of the telescopic rod 152 away from the support arm 111 via a second rotating member 17; the two second side walls 1532b are rotatably connected to the two first side walls 1531b via a third rotating member 18.

[0063] This improves the connection reliability of the second connector 1531, the third connector 1532, the telescopic rod 152, and the guide 151, ensuring that the telescopic rod 152 can move smoothly along the axial direction of the guide channel 151a, so as to ensure the smooth lifting or lowering of the support arm 111, so as to lift and transfer the item to be transferred or lower it after transfer, thereby realizing the rapid transfer of the item to be transferred and improving the transfer efficiency of the item to be transferred.

[0064] In one embodiment, see [reference] Figure 4 As shown, the guide member 151 includes a first connecting shell 1511 and a second connecting sleeve 1512. The first connecting shell 1511 is fixed to the support arm 111. A chamber 1511a is provided inside the first connecting shell 1511, and the chamber 1511a communicates with the through hole 111a. A threaded hole 1511b is provided at one end of the first connecting shell 1511 away from the support arm 111. One end of the second connecting sleeve 1512 extends into the chamber 1511a and is threadedly engaged with the threaded hole 1511b. The other end of the second connecting sleeve 1512 is rotatably connected to the second connecting member 1531. A through channel 1512a is provided on the second connecting sleeve 1512, and the through channel 1512a communicates with the chamber 1511a to form a guide channel 151a.

[0065] Thus, by including the first connecting shell 1511 and the second connecting sleeve 1512, the guide member 151 can be easily connected to the support arm 111 and the second connecting member 1531, so as to form a guide channel 151a on the guide member 151.

[0066] In one embodiment, see [reference] Figure 4 As shown, the first walking assembly 122 includes a first connecting frame 1221 and a first walking wheel 1222; the first connecting frame 1221 is fixedly connected to the first lifting assembly 121; the first walking wheel 1222 is rotatably connected to the first connecting frame 1221; the second walking assembly 132 includes a second connecting frame 1321 and a second walking wheel 1322; the second connecting frame 1321 is fixedly connected to the second lifting assembly 131; the second walking wheel 1322 is rotatably connected to the second connecting frame 1321.

[0067] Therefore, by making the first walking component 122 include a first connecting frame 1221 and a first walking wheel 1222, and the second walking component 132 include a second connecting frame 1321 and a second walking wheel 1322, the first walking component 122 can be easily connected to the first lifting component 121, and the second walking component 132 can be connected to the second lifting component 131, so that the first walking component 122 and the second walking component 132 can cooperate to realize the transfer and movement of the item to be transferred.

[0068] In one embodiment, one of the first traveling wheel 1222 and the second traveling wheel 1322 is a swivel wheel and the other is a directional wheel.

[0069] This allows the transfer device 10 to move freely, facilitating the transfer of items to be transferred.

[0070] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.
