The features defined as "first" and "second" are used to distinguish the feature names, rather than having special meanings. In addition, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise specified, "multiple" means two or more.

[0034] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0035] like Figure 1 and Figure 2 As shown, an embodiment of the present application provides a trolley conveying device, which includes a movable base, a lifting assembly 300 and a drive assembly. The trolley 100 is carried on the top of the conveying device and moves with the conveying device to the loading area of ​​the trolley conveying device. The conveying device places the trolley 100 on the lifting assembly 300 in the loading area. The lifting assembly 300 carries and lifts the height of the trolley 100, so that the trolley 100 is completely separated from the conveying device, which is convenient for the conveying device to leave the trolley conveying device and avoids the trolley 100 from moving during the withdrawal of the conveying device. The movable base carrying the lifting assembly 300 moves from the loading area to the transfer area under the driving action of the drive assembly, thereby transporting the trolley 100 to the transfer area and waiting for the external equipment to further transfer the trolley 100. After the trolley 100 is further transferred, the drive assembly drives the movable base to return to the loading area again for resetting.

[0036] In some examples, the movable base includes a base body 201, which is used to carry the lifting assembly 300. It can be understood that the base body 201 reciprocates between the loading area and the transfer area, driving the lifting assembly 300 to reciprocate between the loading area and the transfer area, thereby completing the transfer work of the trolley 100.

[0037] Furthermore, since the trolley 100 has a certain width, in order to ensure that the lifting assembly 300 stably supports the trolley 100, at least two groups of lifting assemblies 300 are provided, and each group of lifting assemblies 300 is arranged at intervals. Each group of lifting assemblies 300 needs to be arranged on the base body 201, so at least two base bodies 201 are provided.

[0038] In addition, the horizontal positions of each set of lifting components 300 between the loading area and the transfer area need to correspond to each other at all times to prevent the trolley 100 from rotating. Therefore, each base body 201 is fixedly connected to ensure the synchronization of movement. It can be understood that each base body 201 is connected by a crossbeam.

[0039] like Figure 3 As shown, in some examples, the movable base includes a second rolling component 202, which is rotatably connected to the base body 201, thereby improving the smoothness of the movement of the base body 201. When the base body 201 reciprocates between the loading area and the transfer area, the second rolling component 202 rotates to replace the sliding friction with rolling friction. Specifically, the second rolling component 202 includes a roller.

[0040] like Figure 4 As shown, the lifting component 300 is arranged on the top of the base body 201. The lifting component 300 includes a lifting driver 301 and a supporting component 302. The lifting driver 301 is connected to the base body 201. The output end of the lifting driver 301 is connected to the supporting component 302. The lifting driver 301 can drive the supporting component 302 to increase or decrease its height.

[0041] Furthermore, the support component 302 is used to support the trolley 100, and the lifting driver 301 drives the trolley 100 to raise or lower its height through the support component 302. When the conveying device conveys the trolley 100 to the loading area, the support component 302 is at a relatively low height under the action of the lifting driver 301, so that the trolley 100 is conveniently placed on the support component 302; after the trolley 100 is placed on the support component 302, the support component 302 is raised under the action of the lifting driver 301, so that the trolley 100 is separated from the conveying device, so that the conveying device is convenient to evacuate.

[0042] The lifting driver 301 may adopt any structure capable of outputting linear motion. Specifically, the lifting driver 301 adopts a cylinder structure, the cylinder structure is connected to the base body 201 , and the piston rod in the cylinder structure is connected to the supporting component 302 .

[0043] It is understandable that when the trolley 100 has a quadrangular prism shape, four angled positions at the bottom of the trolley 100 are provided with legs, which are placed on the top of the support member 302. To ensure stable support of the trolley 100, two groups of lifting assemblies 300 are provided, and each group of lifting assemblies 300 is used to support two legs on one side of the trolley 100. In addition, each group of lifting assemblies 300 is provided with two lifting drivers 301, and the two lifting drivers 301 are respectively located at the bottom of the two legs.

[0044] like Figure 1 and Figure 2 As shown, in some examples, the support component 302 includes a load-bearing portion 3021, an extension portion 3022 and a connecting portion 3023. The load-bearing portion 3021 is used to place the trolley 100. When the trolley 100 has a quadrangular prism shape, a single support component 302 includes two load-bearing portions 3021, which are respectively used to support two legs on one side of the trolley 100.

[0045] The bearing part 3021 is provided with an upwardly extending folding edge, which is provided at the edge of the bearing part 3021. When the bearing part 3021 supports the legs of the trolley 100, the trolley 100 is prevented from falling to the sides of the device. It is understandable that the folding edge needs to leave space for the trolley 100 to be loaded.

[0046] Further, the connecting portion 3023 is used to connect adjacent bearing portions 3021, and the connecting portion 3023 is connected to the bearing portion 3021 through the extending portion 3022. It can be understood that when a single supporting component 302 includes two bearing portions 3021, two extending portions 3022 are also provided.

[0047] Specifically, the extending portion 3022 and the bearing portion 3021 are at an angle, so that the connecting portion 3023 deviates from the straight line where the bearing portions 3021 are located, thereby reducing the possibility of the connecting portion 3023 and the trolley 100 interfering with each other, which is beneficial to the loading process of the trolley 100 .

[0048] In some examples, the extension portion 3022 extends in a direction close to the base body 201 , and the height of the connection portion 3023 is less than the height of the bearing portion 3021 .

[0049] like Figure 4 As shown, in some examples, the lifting assembly 300 includes a guide assembly, which guides the support component 302 to be lifted or lowered in height to ensure the movement stability of the support component 302 when the height changes.

[0050] The guide assembly is disposed on the base body 201 , and the guide assembly connects the base body 201 and the support component 302 , so that the support component 302 can be raised or lowered along the guide assembly.

[0051] In some examples, the guide assembly includes a guide rod 303 and a limiting component 304, and the guide rod 303 and the limiting component 304 are movably connected. The guide rod 303 is disposed on the support component 302, and the limiting component 304 is disposed on the base body 201; or, the guide rod 303 is disposed on the base body 201, and the limiting component 304 is disposed on the support component 302. The limiting component 304 with a certain length has a hollow cavity, and the guide rod 303 is inserted into the limiting component 304 to prevent the guide rod 303 from moving radially, and the support component 302 is raised or lowered along the axial direction of the guide rod 303.

[0052] In some examples, the driving assembly is connected to the base body 201 , and the driving assembly drives the base body 201 to reciprocate between the loading area and the transfer area.

[0053] like Figure 5 and Figure 6 As shown, the driving assembly includes a transmission assembly and a power assembly, and the power assembly drives the transmission assembly to move so as to move the base body 201. The driving assembly connects the base bodies 201 on both sides of the trolley conveyor to ensure that the base bodies 201 on both sides can move synchronously.

[0054] The transmission assembly includes a first rolling component 401 and a drive shaft 402. The first rolling component 401 is fixedly connected to the drive shaft 402. When the drive shaft 402 rotates, the first rolling component 401 also rotates. It can be understood that the first rolling component 401 is connected to the drive shaft 402 through a key. The rotation of the drive shaft 402 is driven by the power assembly. When the first roller rotates, the base body 201 moves. Specifically, the first rolling component 401 includes a roller. Therefore, the roller of the first rolling component 401 serves as a driving wheel, and the roller of the second rolling component 202 serves as a driven wheel.

[0055] In some examples, the power assembly includes a mobile driver 403 and a reducer 404, wherein the mobile driver 403 is in transmission connection with the reducer 404, and the reducer 404 is in transmission connection with the drive shaft 402. Therefore, the mobile driver 403 drives the drive shaft 402 to rotate through the reducer 404. The mobile driver 403 can adopt any structure that outputs rotational motion, and specifically, the mobile driver 403 adopts a motor.

[0056] Furthermore, the reducer 404 is sleeved on the driving shaft 402, which saves the installation space of the reducer 404 and the mobile driver 403, thereby reducing the floor space of the trolley conveying device.

[0057] In some examples, the trolley 100 transmission device includes a guide rail 501, the guide rail 501 extends from the loading area to the transfer area, and the first rolling component 401 and the second rolling component 202 are in rolling contact with the guide rail 501. Since the first rolling component 401 and the second rolling component 202 are provided on both sides of the trolley conveying device, at least two guide rails 501 are provided. It can be understood that the conveying device carrying the trolley 100 enters the trolley conveying device between the guide rails 501.

[0058] Furthermore, in order to prevent the first rolling member 401 and the second rolling member 202 from being separated from the guide rail 501, the guide rail 501 is provided with a protrusion, and the first rolling member 401 and the second rolling member 202 are both provided with a recess. Alternatively, the guide rail 501 is provided with a recess, and the first rolling member 401 and the second rolling member 202 are both provided with a protrusion, and the protrusion and the recess are mutually engaged. Then the guide rail 501 has a guiding effect on the movement of the base body 201.

[0059] like Figure 7 As shown, in some examples, the trolley conveying device includes a positioning assembly, which is located in the loading area and disposed between the guide rails 501. The positioning assembly is used to receive and position the conveying device to prevent the conveying device from entering the trolley conveying device too much, which makes it difficult for the trolley 100 to be accurately placed on the bearing portion 3021 of the support member 302.

[0060] Furthermore, the positioning assembly includes positioning components arranged at intervals, and the spacing between the positioning components corresponds to the width of the conveying device, so as to ensure that the conveying device can reach between the positioning components without excessively deviating to the movable base on any side.

[0061] The positioning component includes a receiving portion 502 and a blocking portion 503, and the receiving portion 502 and the blocking portion 503 are respectively located at the two ends of the positioning component, and the receiving portion 502 is located at the end away from the transfer area, and the blocking portion 503 is located at the end close to the transfer area. The spacing between the receiving portions 502 gradually increases in the direction away from the transfer area. When the conveying device does not accurately correspond to the space between adjacent positioning components, the conveying device will contact the receiving portion 502 during the movement, and the receiving portion 502 will guide the conveying device to the correct position. When the conveying device moves to the right position, the conveying device contacts the blocking portion 503 to prevent the conveying device from moving over the travel.

[0062] During the actual implementation process, the mobile driver 403 drives the first rolling component 401 to rotate, the base body 201 moves along the guide rail 501 to the loading area, and the lifting driver 301 drives the support component 302 to lower its height, waiting for the loading of the trolley 100; the conveying device carrying the trolley 100 reaches the specified position of the loading area under the limiting action of the positioning component, and places the trolley 100 on the top of the support component 302; the lifting driver 301 drives the support component 302 to raise its height, so that the trolley 100 is separated from the conveying device, and the subsequent movement of the conveying device causes the position of the trolley 100 to be shifted; the conveying device withdraws from the trolley conveying device, and at the same time, the mobile driver 403 drives the first rolling component 401 to rotate, and the base body 201 moves along the guide rail 501 to the transfer area, waiting for the external equipment to further transfer the trolley 100; the lifting driver 301 drives the support component 302 to lower its height, and the mobile driver 403 drives the base body 201 back to the loading area to complete the resetting of the device.

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0064] The above describes the implementation methods of the present application in detail in conjunction with the accompanying drawings, but the present application is not limited to the above implementation methods. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present application.
