Description

Technical Field

[0001] This application relates to the field of battery technology, and in particular to a device for picking up and placing inserts and a method for transporting inserts. Background Technology

[0002] Currently, energy storage containers are widely used in power systems to balance power supply and demand. However, during the use of energy storage containers, the maintenance and installation of the internal modules rely entirely on manual handling and disassembly, without specialized maintenance equipment. When there are modules requiring maintenance in each cluster, they must be disassembled and installed sequentially from bottom to top, making it impossible to only remove the problematic module, resulting in a large workload for maintenance. In addition, the space available for energy storage container layouts is becoming increasingly limited, with small gaps not only between adjacent containers but also between containers and walls. This results in insufficient working space when using forklifts to move modules, hindering effective module handling. Summary of the Invention

[0003] Based on the existing problems of energy storage containers, this application proposes a container insertion and removal device and a container handling method, which can not only remove and place containers in a small space, but also accurately remove and place containers that need maintenance inside the energy storage container.

[0004] To achieve the above objectives, in a first aspect, this application provides a box insertion and removal device, including a frame, a drive mechanism, and a push-pull mechanism, wherein the drive mechanism and the push-pull mechanism are respectively disposed on the frame; The push-pull mechanism includes a box connector, an extension push rod, and a push-pull connector arranged along a first direction. The extension push rod is detachably connected between the box connector and the push-pull connector, and the box connector and the push-pull connector are detachably connected. The insert connector is used to fix an insert box placed inside the container. The push-pull connector is connected to the drive mechanism, which drives the push-pull connector to move back and forth along the first direction. When the push-pull mechanism is configured as a structure consisting of the insert connector, the extension push rod, and the push-pull connector connected in sequence, the insert connector and at least a portion of the extension push rod can protrude from the first end of the frame along the first direction and extend into the container. When the push-pull mechanism is configured as a structure consisting of the insert connector and the push-pull connector, the insert connector can be close to the second end of the chassis along the first direction, such that the insert box fixed to the insert connector is completely located on the frame.

[0005] The container insertion and removal device described above offers at least the following advantages: Designing the push-pull mechanism as a detachable container connector, extension push rod, and push-pull connector allows for adjustments to the mechanism's length to accommodate different usage requirements. When removing or inserting a container from or into the container, the extension push rod is installed between the container connector and the push-pull connector to increase the mechanism's length, ensuring the connector can secure the container to the container or push it into the container. When transferring the container to the rack, the extension push rod is removed to reduce the rack length occupied by the push-pull mechanism, ensuring the container is fully positioned on the rack. Therefore, even in confined spaces, this device facilitates precise placement and removal of individual containers requiring maintenance.

[0006] Secondly, this application provides a handling method for retrieving and placing inserts located inside a container using the insert retrieval and placement device of the first aspect, the handling method comprising: Connect the insert connector, the extension push rod, and the push-pull connector in sequence; Fix the box loading and unloading device to the forklift, and move the forklift to a preset position and preset height; The push-pull mechanism is driven by the drive mechanism to move toward the container in the first direction, so that the insert connector extends into the container and is fixed to the insert container; The push-pull mechanism is driven by a drive mechanism to move away from the container along the first direction until a portion of the inserted container is located on the frame; Remove the extension push rod; The push-pull connector is driven by a drive mechanism to move toward the insert connector and connect the push-pull connector to the insert connector; The push-pull connector is moved away from the container by a drive mechanism until the insert is fully positioned on the frame. Remove the insert box from the rack.

[0007] The aforementioned method for handling insert boxes has at least the following advantages: This method utilizes an insert box retrieval and placement device to remove insert boxes from a container. During this process, an extension push rod is first used to increase the overall length of the push-pull mechanism, allowing the insert box connector to enter the container and be secured to the insert box. Subsequently, when moving the insert box onto the rack, the extension push rod can be removed, reducing the space occupied by the push-pull mechanism on the rack and ensuring the insert box is fully positioned on the rack. Thus, by setting a detachable extension push rod, not only can individual insert boxes be directly removed, but insert box retrieval and placement can also be performed within a relatively small space.

Detailed Implementation

[0010] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0011] refer to Figure 1 The insert box retrieval device 100 in this embodiment can be used to remove the insert box 20 from the container 10 for maintenance of the insert box 20. The insert box retrieval device 100 can also be used to send the repaired insert box 20 into the container 10.

[0012] refer to Figures 2 to 4 The insert box loading and unloading device 100 may include a frame 110, a drive mechanism 130, and a push-pull mechanism 120, with the drive mechanism 130 and the push-pull mechanism 120 respectively mounted on the frame 110. Specifically, the push-pull mechanism 120 may include an insert box connector 121, an extension push rod 122, and a push-pull connector 123 arranged along a first direction. The extension push rod 122 is detachably connected between the insert box connector 121 and the push-pull connector 123, and the insert box connector 121 and the push-pull connector 123 are also detachably connected. The drive mechanism 130 is drively connected to the push-pull connector 123 to drive the push-pull connector 123 to move back and forth along the first direction.

[0013] Combination Figure 1 and Figure 4 The frame 110 has a first end and a second end arranged along a first direction. When the insert box 20 located inside the container 10 is picked up or placed using the insert box picking and placing device 100, the first end is close to the container 10. At this time, the insert box connector 121 is located between the first end of the frame 110 and the push-pull connector 123. The insert box connector 121 can be used to fix the insert box 20 placed inside the container 10. When the push-pull mechanism 120 is configured as a structure consisting of the insert box connector 121, the extension push rod 122 and the push-pull connector 123, under the drive of the drive mechanism 130, the insert box connector 121 and at least part of the extension push rod 122 can protrude from the first end of the frame 110 along the first direction, and the insert box connector 121 can extend into the container 10. When the push-pull mechanism 120 is configured as a structure consisting of a box connector 121 and a push-pull connector 123, under the drive of the drive mechanism 130, the box connector 121 can approach the second end of the chassis along the first direction, so that the box 20 fixed to the box connector 121 is completely located on the frame 110.

[0014] Understandably, in this embodiment, the extension push rod 122 is used to change the overall length of the push-pull mechanism 120. When the extension push rod 122 is connected between the push-pull connector 123 and the container connector 121, the length of the push-pull mechanism 120 increases. When the extension push rod 122 is removed, and only the push-pull connector 123 and the container connector 121 are connected, the length of the push-pull mechanism 120 decreases. Due to the small operating space, the dimensions of the frame 110 along the first direction will not be too large, and the movement distance of the push-pull connector 123 is limited. By adding the extension push rod 122, the distance by which the container connector 121 protrudes from the first end of the frame 110 can be increased, so that the container connector 121 can extend into the container 10.

[0015] When the insert box 20 inside container 10 needs maintenance, the insert box retrieval device 100 can be fixed to forklift 30, and the forklift 30 can be used to raise the insert box retrieval device 100 to the corresponding height. An extension push rod 122 is connected between the insert box connector 121 and the push-pull connector 123. The drive mechanism 130 drives the push-pull connector 123 to move closer to container 10 in a first direction, causing the insert box connector 121 to extend into container 10 and secure the insert box 20 to it. Subsequently, the drive mechanism 130 drives the push-pull connector 123 to move away from container 10 in the first direction, causing the insert box connector 121 to pull the insert box 20 out of container 10. When part of the insert box 20 is on the rack 110, the extension push rod 122 can be removed, the insert box connector 121 can be connected to the push-pull connector 123, and then the push-pull connector 123 can be driven to move away from the container 10 until the insert box 20 is completely on the rack 110, thus completing the removal of a single insert box 20 from the container 10.

[0016] When the insert box 20 is fully positioned on the rack 110, the forklift 30 can drive the insert box pick-and-place device 100 to a preset position to facilitate the removal of the insert box 20 from the rack 110 for maintenance. After the insert box 20 has been maintained, the connection between the insert box connector 121 and the push-pull connector 123 is maintained, and the insert box 20 is placed on the rack 110, thus securing the insert box connector 121 to the insert box 20. The drive mechanism 130 drives the push-pull connector 123 to move closer to the container 10, so that a portion of the insert box 20 is located in the container 10. Then, the extension push rod 122 is connected between the insert box connector 121 and the push-pull connector 123, and the push-pull connector 123 is driven closer to the container 10 again until the insert box connector 121 extends into the container 10, placing the insert box 20 in place.

[0017] In this embodiment, the insert box retrieval device 100 designs the push-pull mechanism 120 as a detachable insert box connector 121, an extension push rod 122, and a push-pull connector 123 to change the length of the push-pull mechanism 120 to adapt to different usage requirements. When it is necessary to extend the insert box connector 121 into the container 10 to fix it to the insert box 20 or to send the insert box 20 into the container 10, the extension push rod 122 is installed between the insert box connector 121 and the push-pull connector 123 to increase the length of the push-pull mechanism 120. When it is necessary to transfer the insert box 20 to the rack 110, the extension push rod 122 is removed to reduce the length of the rack 110 occupied by the push-pull mechanism 120, thereby ensuring that the insert box 20 can be completely positioned on the rack 110. Therefore, even in a small space, the insert box retrieval device 100 in this embodiment can easily and accurately retrieve and place a single insert box 20 that needs maintenance.

[0018] refer to Figure 4 and Figure 5 The frame 110 may include two main frames 111 arranged along a second direction and a support frame 112 located at the bottom of the main frames 111. At least two support frames 112 may be included, and each support frame 112 can be fixed to the main frame 111 by welding. Here, the second direction is perpendicular to the first direction. In practical applications, the first direction can be considered as the length direction of the frame 110, and the second direction can be considered as the width direction of the frame 110. There is a storage space between the two main frames 111, and the drive mechanism 130 and the push-pull mechanism 120 can be disposed between the two main frames 111 to provide sufficient space for the back-and-forth movement of the push-pull mechanism 120.

[0019] refer to Figure 4 and Figure 6 The drive mechanism 130 may include a drive component 131, a transmission component 132, and a drive chain 133. The drive chain 133 is connected to the drive component 131 through the transmission component 132, and the push-pull connector 123 is connected to the drive chain 133 so that the drive component 131 can drive the push-pull connector 123 to move along a first direction.

[0020] Specifically, there may be two drive chains 133, which are arranged at intervals along the second direction and respectively close to the two main frames 111. In this case, the transmission component 132 may be configured as a transmission shaft with its axis parallel to the second direction, and the drive component 131 is connected to the transmission component 132 so that the drive component 131 can drive the transmission component 132 to rotate around the axis of the transmission component 132.

[0021] Furthermore, the drive component 131 and the transmission component 132 can be disposed at the second end of the frame 110 along the first direction, and each main frame 111 is provided with a fixing member 115 at the first end along the first direction. The drive chain 133 has a ring structure, with two drive chains 133 respectively sleeved on both ends of the transmission component 132, and each drive chain 133 is also sleeved on the corresponding fixing member 115. When the drive component 131 drives the transmission component 132 to rotate, the links of the drive chain 133 can move along the first direction, thereby realizing the movement of the push-pull connector 123 in the first direction.

[0022] Understandably, the two ends of the push-pull connector 123 along the second direction can be connected to the two drive chains 133 respectively, which ensures that the push-pull connector 123 is subjected to balanced force, thereby ensuring that the push-pull connector 123 remains stable when moving. In addition, by setting the structural components of the drive chain 133 and the push-pull connector 123, the moving distance of the push-pull connector 123 relative to the frame 110 is basically equal to the dimension of the frame 110 along the first direction. This increases the moving space of the push-pull connector 123, and makes it easier to disassemble and assemble the extension push rod 122 during the process of picking up and putting down the insert box 20.

[0023] In some possible implementations, the drive component 131 and the transmission component 132 can be arranged along a third direction, that is, the drive component 131 can be located at the bottom of the transmission component 132. Here, the third direction is perpendicular to the first direction and perpendicular to the second direction. In practical applications, the third direction can also be regarded as a vertical direction. By arranging the drive component 131 and the transmission component 132 vertically, it is beneficial to reduce the space occupied by the drive mechanism 130 in the first direction, thereby reducing the size of the frame 110 in the first direction. Since the reserved working space of the box loading and unloading device 100 mainly affects the size of the frame 110 in the first direction when it is working, reducing the size of the frame 110 can adapt to more scenarios of small-space operation.

[0024] In a specific implementation, the drive component 131 can be, for example, a motor. When it is necessary to drive the push-pull connector 123 to move towards the container 10, the motor can be controlled to rotate forward; when it is necessary to drive the push-pull connector 123 to move away from the container 10, the motor can be controlled to rotate backward. In this way, the motor can respond quickly and is easy to operate during the reciprocating movement of the push-pull connector 123.

[0025] In some embodiments, reference Figure 7 and Figure 8The insertion box 20 may include a base plate 21 and a box body 22. The box body 22 is connected above the base plate 21, and the edge of the base plate 21 protrudes from the box body 22. At this time, when the insertion box connector 121 is fixed to the insertion box 20, the insertion box connector 121 can be fixed to the base plate 21. This will not only not affect the internal structure of the insertion box 20, but also facilitate operation.

[0026] Specifically, the insert box connector 121 may include an insert box connecting portion 1211 extending along the second direction. The insert box connecting portion 1211 may be a sheet-like structure, and it has a plurality of threaded holes 12111 arranged along the second direction. Correspondingly, the base plate 21 of the insert box 20 may also have a plurality of locking holes, at least some of which are threaded holes 12111 corresponding to the locking holes. When the insert box connector 121 is fixed to the insert box 20, the insert box connecting portion 1211 can be fitted to the base plate 21, and screws can be passed through the threaded holes 12111 and fixed to the locking holes on the base plate 21. In this way, the disassembly and assembly of the insert box 20 and the insert box connector 121 are very convenient, which helps to improve work efficiency.

[0027] The insert connector 121 may further include a first limiting part 1212 and a second limiting part 1213. Both the first limiting part 1212 and the second limiting part 1213 are sheet-like structures. The first limiting part 1212 and the insert connector 1211 are arranged along a third direction, and the second limiting part 1213 is connected between the insert connector 1211 and the first limiting part 1212. In this case, the insert connector 121 can be regarded as a U-shaped structure. The insert connector 1211 and the first limiting part 1212 can respectively abut against two surfaces of the base plate 21 along a third direction, and the second limiting part 1213 can abut against the side surface of the base plate 21 facing the push-pull connector 123. When the insert box connector 121 is fixed to the insert box 20, the opening of the U-shaped structure can face the base plate 21, and the edge of the base plate 21 can be inserted between the first limiting part 1212 and the insert box connector 1211. This improves the positioning accuracy of the base plate 21 and the insert box connector 121, facilitating the quick positioning of the screw holes and locking holes. In addition, the three surfaces of the base plate 21 contact the insert box connector 121, increasing the contact area between the base plate 21 and the insert box connector 121, and also enhancing the fixing effect between the insert box connector 121 and the insert box 20, preventing the insert box 20 from becoming loose during the pushing and pulling of the insert box 20.

[0028] Continue to refer to Figure 7The insert box connector 121 may further include a first connecting portion 1214 connected to the side of the insert box connecting part 1211 facing the push-pull connector 123. The first connecting portion 1214 can be fixed to the second limiting part 1213, and the first connecting portion 1214 is provided with a first connecting hole 12141. The first end of the extension push rod 122 is provided with a second connecting portion 1221, and the second connecting portion 1221 is provided with a second connecting hole 12211. Both the first connecting hole 12141 and the second connecting hole 12211 can be pin holes. When the insert box connector 121 is connected to the extension push rod 122, the first connecting portion 1214 and the second connecting portion 1221 can be overlapped vertically, so that the first connecting hole 12141 and the second connecting hole 12211 are aligned, and connected by a pin passing through the first connecting hole 12141 and the second connecting hole 12211.

[0029] The first connecting hole 12141 can also be a strip-shaped hole extending along the first direction, that is, the size of the first connecting hole 12141 in the first direction is larger than the size of the second connecting hole 12211 in the first direction. When the first connecting hole 12141 and the second connecting hole 12211 are connected by a pin, during the process of the push-pull connector 123 driving the insert box connector 121 to move through the extension push rod 122, there is a certain amount of relative movement between the extension push rod 122 and the insert box connector 121, which can prevent the insert box 20 from deforming during the movement.

[0030] Furthermore, the insert connector 121 may also include a first limiting block 1215 fixed to the second limiting portion 1213, the first limiting block 1215 and the first connecting portion 1214 being spaced apart along a third direction. When the first connecting portion 1214 and the second connecting portion 1221 are connected, the second connecting portion 1221 may be located between the first connecting portion 1214 and the first limiting block 1215, and the first limiting block 1215 may abut against a portion of the surface of the second connecting portion 1221, thereby limiting the second connecting portion 1221 in the vertical direction and preventing the first connecting portion 1214 and the second connecting portion 1221 from moving up and down, which would cause the insert connector 121 and the extension push rod 122 to become unstable.

[0031] There can be two first connecting portions 1214, which are disposed at both ends of the second limiting portion 1213 along the second direction. Similarly, there are also two second connecting portions 1221, with each second connecting portion 1221 correspondingly connected to one first connecting portion 1214. In this way, the stability of the connection between the first connecting portion 1214 and the second connecting portion 1221 can be further improved.

[0032] Continue to refer to Figure 7The second end of the extension push rod 122 is provided with a third connecting part 12221, and the second connecting part 1221 is provided with a third connecting hole. The push-pull connector 123 includes a fourth connecting part 1231, and the fourth connecting part 1231 is provided with a fourth connecting hole 12311. Both the third connecting hole and the fourth connecting hole 12311 can be pin holes. When the push-pull connector 123 and the extension push rod 122 are connected, they can be connected by a pin passing through the third connecting hole and the fourth connecting hole 12311.

[0033] The push-pull connector 123 may also include a second limiting block 1232, which is spaced apart from the fourth connecting part 1231 along a third direction. When the third connecting part 12221 and the fourth connecting part 1231 are connected, the third connecting part 12221 may be located between the fourth connecting part 1231 and the second limiting block 1232, and the second limiting block 1232 may abut against a portion of the surface of the third connecting part 12221, thereby limiting the third connecting part 12221 in the vertical direction and preventing the third connecting part 12221 and the fourth connecting part 1231 from moving up and down, which would cause the extension push rod 122 and the push-pull connector 123 to become unstable.

[0034] There can be two third connecting parts 12221, which are spaced apart along the second direction. Similarly, there are also two fourth connecting parts 1231, with each fourth connecting part 1231 corresponding to one third connecting part 12221. In this way, the stability of the connection between the third connecting parts 12221 and the fourth connecting parts 1231 can be further improved.

[0035] It is worth mentioning that, in this embodiment, the first connecting part 1214 and the fourth connecting part 1231 can also be connected by a pin passing through the first connecting hole 12141 and the fourth connecting hole 12311, so that the push-pull connector 123 and the insert box connector 121 can be connected. In this way, not only can the extension push rod 122 be connected between the insert box connector 121 and the push-pull connector 123, but the connection between the insert box connector 121 and the push-pull connector 123 can also be realized, which can easily and quickly change the length of the push-pull mechanism 120 to meet different usage requirements.

[0036] In some embodiments, reference Figure 4 and Figure 7The push-pull connector 123 may also be provided with guide rollers 1233 on both sides along the second direction. The axis of the guide rollers 1233 is parallel to the second direction, and the guide rollers 1233 can rotate relative to the push-pull connector 123 about their own axis. The frame 110 may be provided with guide rails 116 corresponding to the guide rollers 1233. Specifically, each main frame 111 may be provided with guide rails 116. The guide rails 116 extend along the first direction, and the guide rollers 1233 are movably disposed on the guide rails 116 relative to the guide rails 116 along the first direction.

[0037] During the movement of the push-pull connector 123 relative to the frame 110 along the first direction, it can drive the guide roller 1233 to move relative to the guide rail 116. Furthermore, the guide roller 1233 can also rotate relative to the guide rail 116 around its own axis. At this time, the guide rail 116 and the guide roller 1233 can cooperate to limit the movement direction of the push-pull connector 123, ensuring that the push-pull connector 123 can move in the preset direction. They can also support the push-pull connector 123, ensuring its smooth movement.

[0038] Looking back Figures 2 to 5 The insert box loading and unloading device 100 may further include two sets of support components 140 disposed on the frame 110. The two sets of support components 140 are respectively disposed on both sides of the push-pull mechanism 120 along the second direction. Specifically, the two sets of support components 140 may be disposed on the two main frames 111 respectively. When the insert box 20 is pulled out onto the frame 110 by the push-pull mechanism 120, the two sets of support components 140 may be used to support the two side edges of the bottom of the insert box 20. That is, when the insert box 20 moves on the frame 110, the middle part of the insert box 20 is suspended, and only the two side edges are supported by the support components 140. It is worth noting that since the middle part of the insertion box 20 is usually equipped with a liquid cooling plate, the liquid cooling plate is easily damaged if it is subjected to force during the movement of the insertion box 20 on the frame 110. Therefore, by setting two sets of support components 140 to support the two sides of the insertion box 20, it is possible not only to ensure that the insertion box 20 moves stably on the frame 110, but also to avoid damage to the internal structure of the insertion box 20.

[0039] Specifically, each set of support components 140 may include a plurality of support rollers 141 arranged along a first direction, the axis of each support roller 141 being parallel to a second direction, and each support roller 141 being rotatable relative to the frame 110 about its own axis. When the insert box 20 moves on the frame 110, there is friction between the insert box 20 and the support rollers 141, and the support rollers 141 can rotate under the action of friction. Since the friction between the insert box 20 and the support rollers 141 is rolling friction, this reduces the magnitude of the friction between the insert box 20 and the support rollers 141, so that the insert box 20 can move more smoothly on the frame 110.

[0040] As an alternative implementation scheme, such as Figure 5 As shown, mounting slots 113 can be provided on both sides of the frame 110 along the second direction, that is, each main frame 111 is provided with a mounting slot 113, which extends along the first direction. The mounting slot 113 has a certain width along the second direction, and the two side walls of the mounting slot 113 along the second direction are respectively provided with shaft grooves 114 corresponding to multiple support rollers 141 in a set of support rollers 141. The support assembly 140 may also include a shaft corresponding to multiple support rollers 141. The two ends of the shaft can be fixed in a set of shaft grooves 114 respectively, and the support rollers 141 are sleeved on the shaft and can rotate around the shaft. In this way, the mounting slots 113 can be used to accommodate the support rollers 141, and the shaft grooves 114 can support the support rollers 141 and ensure that the support rollers 141 can rotate relative to the frame 110.

[0041] In some embodiments, reference Figure 3 The insert box loading and unloading device 100 may further include a limiting mechanism 150 disposed on the frame 110. The limiting mechanism 150 can be used to limit the insert box 20 located on the frame 110. Specifically, the limiting mechanism 150 may include two sets of first stop blocks 151 arranged along the second direction. The two sets of first stop blocks 151 are respectively located on both sides of the two sets of support components 140 along the second direction and are respectively fixed on the two main frames 111. The two sets of first stop blocks 151 can cooperate to limit the insert box 20 in the second direction. In specific implementation, the distance between the two sets of first stop blocks 151 is greater than the size of the insert box 20 in the second direction, so as to ensure that the insert box 20 will not come into contact with the first stop blocks 151 when it moves on the frame 110. At the same time, the first stop blocks 151 on both sides can also prevent the insert box 20 from falling off the frame 110.

[0042] Each set of first stop blocks 151 may include at least two first stop blocks 151 arranged at intervals, so that when multiple first stop blocks 151 limit the insertion box 20, the length direction of the insertion box 20 is basically consistent with the length direction of the frame 110, so as to avoid the insertion box 20 being tilted on the frame 110 and unable to be smoothly inserted.

[0043] Along the third direction, the end of the first stop block 151 away from the frame 110 may also be provided with a guide surface inclined in the third direction. The dimension of the end of the guide surface away from the frame 110 in the third direction and the dimension of the push-pull mechanism 120 in the second direction are larger than the dimension of the end of the guide surface close to the frame 110 in the third direction and the dimension of the push-pull mechanism 120 in the second direction. When the insert box 20 is repaired and sent into the container 10 by means of the insert box loading and unloading device 100, the insert box 20 needs to be placed on the frame 110. During the placement of the insert box 20, the guide surfaces on both sides can make it easier to place the insert box 20 between the first stop blocks 151 on both sides, avoiding collision between the bottom of the insert box 20 and the first stop block 151.

[0044] Furthermore, the limiting mechanism 150 in this embodiment may also include a second stop block 152 and a third stop block 153, which are respectively disposed at the first end and the second end of the frame 110 along the first direction to limit the insertion box 20 in the first direction. The second stop block 152 is detachably connected to the frame 110. Since the insertion box 20 needs to move gradually from the first end of the frame 110 towards the second end, the second stop block 152 can be removed from the frame 110 during the movement of the insertion box 20 relative to the frame 110 to avoid interference with the insertion box 20. When the insertion box 20 is relatively fixed to the frame 110 and there is no relative movement, the second stop block 152 can be installed on the frame 110. In this case, the second stop block 152 and the third stop block 153 can cooperate to limit the insertion box 20, preventing the insertion box 20 from sliding out of the frame 110.

[0045] Similarly, along the third direction, a guide surface may be provided at the end of the second stop block 152 away from the frame 110, and a guide surface may also be provided at the end of the third stop block 153 away from the frame 110, so that when the insert box 20 is placed on the frame 110, the insert box 20 can more easily enter between the second stop block 152 and the third stop block 153.

[0046] For example, two second stop blocks 152 may be provided, arranged at intervals along the second direction, and the distance between the two second stop blocks 152 is less than the dimension of the insert box 20 in the second direction. For example, two third stop blocks 153 may also be provided, arranged at intervals along the third direction, and the distance between the two third stop blocks 153 is less than the dimension of the insert box 20 in the second direction.

[0047] In addition, when the second stop block 152 is installed with the frame 110, the second stop block 152 and the frame 110 can be provided with pin holes respectively. The second stop block 152 and the frame 110 can be connected by pins that pass through the two pin holes, so as to facilitate frequent disassembly and assembly between the second stop block 152 and the frame 110.

[0048] In some embodiments, continue to refer to Figure 3 The frame 110 is also provided with two sets of positioning components 160. The two sets of positioning components 160 are located on both sides of the push-pull mechanism 120 along the second direction. Each set of positioning components 160 can be set on the main frame 111 to contact the bottom plate 21 of the insertion box 20 on both sides along the second direction.

[0049] In one alternative implementation, combined with Figure 3 and Figure 9 The positioning component 160 may include a positioning wheel 164, a mounting base 161, a fixing block 162, and a screw 163. The mounting base 161 may include a first mounting plate 1611 and a second mounting plate 1612, with the second mounting plate 1612 connected to the side of the first mounting plate 1611 away from the push-pull mechanism 120. The fixing block 162 is disposed on the first mounting plate 1611, and the positioning wheel 164 is connected to the side of the fixing block 162 opposite to the second mounting plate 1612. The axis of the positioning wheel 164 is parallel to a third direction, and the positioning wheel 164 can rotate relative to the fixing block 162 about its own axis. The screw 163 passes through the second mounting plate 1612 along a second direction, and the end of the screw 163 located on the second mounting plate 1612 facing the fixing block 162 is fixedly connected to the fixing block 162.

[0050] When the positioning component 160 is used to position the insertion box 20, the positioning wheel 164 can contact the insertion box 20. During the movement of the insertion box 20 in the first direction, the positioning wheel 164 can rotate around its own axis and always maintain contact with the insertion box 20, thereby achieving the positioning of the insertion box 20.

[0051] Understandably, when the positioning wheel 164 is set and its position is adjusted, the positioning wheel 164 can be used to adjust the position of the insert box 20 located on the frame 110, so as to ensure that the insert box 20 can be centered on the frame 110 along the second direction. In this way, when the insert box 20 is sent into the container 10 by the insert box picking and placing device 100, the positioning between the insert box 20 and the container 10 can be achieved, ensuring that the insert box 20 is placed in place.

[0052] When it is necessary to adjust the position of the positioning wheel 164 in the second direction, the screw 163 can be turned so that the screw 163 moves forward toward the push-pull mechanism 120 or moves away from the push-pull mechanism 120 and backward. While the screw 163 moves, the fixing block 162 can drive the positioning wheel 164 to move synchronously, thereby changing the distance between the positioning wheels 164 on both sides.

[0053] Furthermore, the positioning component 160 may also include two limiting bolts 165 disposed on the first mounting plate 1611, with the two limiting bolts 165 respectively located on both sides of the fixing block 162 along the first direction. The fixing block 162 has a limiting groove 1621 on one side facing each limiting bolt 165, and the limiting groove 1621 can penetrate the fixing block 162 along the second direction. At this time, the side of the fixing block 162 contacts the rod portion of the limiting bolt 165, and the limiting groove 1621, close to the side wall of the first mounting plate 1611, contacts the head of the limiting bolt 165. Thus, the limiting bolts 165 can limit the fixing block 162 in the third direction, preventing the fixing block 162 from tilting and changing the orientation of the positioning wheel 164, thereby ensuring the positioning effect of the positioning wheel 164 on the insertion box 20.

[0054] At least two positioning components 160 can be provided on each side, and the positioning components 160 and the first limiting block can be staggered in the first direction, so that the distance between two adjacent positioning components 160 is larger, which can improve the positioning effect of the insertion box 20.

[0055] In some embodiments, continue to refer to Figure 3 The frame 110 can also be provided with forklift matching locking mechanisms 170 on both sides along the second direction. The forklift matching locking mechanisms 170 can cooperate with the fork teeth of the forklift 30 and be locked and fixed by bolts to ensure that the frame 110 and the forklift 30 remain fixed during operation.

[0056] The bottom of the forklift-equipped locking mechanism 170 can also be equipped with a shock-absorbing base 171. When the container loading and unloading device 100 is placed on the ground, the shock-absorbing base 171 is in direct contact with the ground. By setting the shock-absorbing base 171, when the container 20 is taken out of the container 10 using the forklift 30 and the container loading and unloading device 100, and then the container loading and unloading device 100 is placed on the ground, the shock-absorbing base 171 can reduce the vibration between the container loading and unloading device 100 and the ground, thus preventing damage to the container 20.

[0057] It is worth mentioning that, in this embodiment, when the container insertion and placement device 100 works with the forklift 30 to pick up and place the container 20, the movement direction of the forklift 30 is perpendicular to the length direction of the frame 110. That is, when using the forklift 30, it only needs to move along the extension direction of the passage between two adjacent containers 10; it does not need to turn around and use its forks to remove the container 20. Thus, even if the space between two adjacent containers 10 is small, it only needs to be large enough to accommodate the container insertion and placement device 100. The dimensions of the container insertion and placement device 100 can be designed according to the reserved space. Based on this, the length of the extension push rod 122 can be designed according to actual operational needs to achieve the picking and placing of the container 20.

[0058] In the process of designing the insert box retrieval and placement device 100, it is necessary not only to design the dimensions of the frame 110, but also to design the strength of the frame 110 to ensure that no safety hazards will be generated during the retrieval and placement of the insert box 20.

[0059] In practical applications, the main frame 111 and drive chain 133 need to be designed to prevent severe deformation of the main frame 111 and breakage of the drive chain 133. The model of the drive chain 133 can be determined based on the weight of the insert 20 and the maximum friction between the insert 20 and the container 10 during loading and unloading. The model of the main frame 111 can be determined based on the design load of the frame 110, the dimensions of the frame 110 along the first direction, and the dimensions of the frame 110 along the second direction. The design load of the frame 110 can be determined based on the weight of the insert 20.

[0060] For example, the design load G of the insert box 20 to be repaired is determined to be less than or equal to 600 kg, taking into account compatibility with later products. 重 It weighs 800 kg. Simultaneously, it provides maximum thrust (i.e., the frictional force between the insert 20 and the container 10). 10KN, the size of the insert box retrieval device 100 along the first direction is less than or equal to 2.2 meters, and the size along the second direction is less than or equal to 0.85 meters.

[0061] When designing rack 110, according to G 重 For a frame weighing 800kg, the material for the main frame 111 was selected as steel. Simultaneously, the deformation of the frame 110 was controlled to be within 1mm. Using formula The moment of inertia of the main frame 111 section was calculated. =2400 Therefore, two 200mm rods can be selected. 100mm 8mm rectangular tube ( =2306 The main frame is cut and welded for use, and the final product is formed. =2850 ≥ The requirements are met.

[0062] When designing the drive mechanism 130, based on the thrust... 10KN, using a double-drive chain 133, the theoretical thrust of a single-drive chain 133 is obtained. KN, with a safety factor of 8 according to design specifications, uses a single drive chain with an actual thrust of 133. KN, therefore, the 80 series chain was selected. KN≥ This meets the design requirements. Additionally, the motor can be selected according to the selection manual with a reduction ratio of 7 and a torque of 200 Nm. m geared motor.

[0063] Based on the same design concept, this application can also provide a method for handling and repairing the insert box 20 located inside the container 10 using the insert box retrieval and placement device 100 described in the above embodiments, combined with Figures 1 to 4 The handling method may specifically include the following steps: Step S101: Connect the insert box connector 121, the extension push rod 122, and the push-pull connector 123 in sequence; Step S102: Fix the box loading and unloading device 100 to the forklift 30, and move the forklift 30 to the preset position and preset height; Step S103: Drive the push-pull mechanism 120 to move toward the container 10 in the first direction using the drive mechanism 130, so that the insert connector 121 extends into the container 10 and fixes the insert connector 121 to the insert 20. Step S104: Drive the push-pull mechanism 120 to move away from the container 10 along the first direction using the drive mechanism 130 until a portion of the insert 20 is located on the frame 110; Step S105: Remove the extension push rod 122; Step S106: Drive the push-pull connector 123 towards the insertion box connector 121 using the drive mechanism 130, and connect the push-pull connector 123 to the insertion box connector 121; Step S107: Use the drive mechanism 130 to drive the push-pull connector 123 away from the container 10 until the insert 20 is completely on the frame 110; Step S108: Remove the insert box 20 from the rack 110.

[0064] In the above-described handling method, steps S101 to S108 involve using the insert box retrieval device 100 to remove the insert box 20 from the container 10. During this process, the overall length of the push-pull mechanism 120 is increased using the extension push rod 122 to allow the insert box connector 121 to enter the container 10 and be fixed to the insert box 20. Subsequently, when the insert box 20 is moved to the rack 110, the extension push rod 122 can be removed to reduce the space occupied by the push-pull mechanism 120 on the rack 110, thus ensuring that the insert box 20 is completely positioned on the rack 110. Therefore, by providing the detachable extension push rod 122, not only can a single insert box 20 be directly removed, but the insertion and placement of the insert box 20 can also be performed within a relatively small space.

[0065] Furthermore, after completing the above step S108 and the repair of the insertion box 20, the handling method in this embodiment may further include the following steps: Step S109: Keep the push-pull connector 123 connected to the insert box connector 121, place the insert box 20 on the frame 110, and fix the insert box connector 121 to the insert box 20; Step S110: Fix the box loading and unloading device 100 to the forklift 30, and move the forklift 30 to the preset position and preset height; Step S111: Drive the push-pull connector 123 to move toward the container 10 in the first direction using the drive mechanism 130 until a part of the insert 20 is inside the container 10; Step S112: Separate the push-pull connector 123 from the insert connector 121; Step S113: Drive the push-pull connector 123 away from the insert box connector 121 using the drive mechanism 130, and connect the extension push rod 122 between the push-pull connector 123 and the insert box connector 121; Step S114: Drive the push-pull connector 123 to move toward the container 10 in the first direction using the drive mechanism 130 until the insert 20 is completely inside the container 10; Step S115: Separate the insert connector 121 from the insert box 20.

[0066] Understandably, steps S109 to S115 described above can be used to reinsert the repaired insert box 20 into the container 10. During this process, to ensure the insert box 20 can be fully placed on the frame 110, the extension push rod 122 is not installed initially. Then, the insert box 20 is partially fed into the container 10 using the insert box connector 121 and the push-pull connector 123. Next, the extension push rod 122 is connected to the insert box connector 121 and the push-pull connector 123 to ensure the overall length of the push-pull mechanism 120 is sufficient. Finally, the insert box 20 is fully pushed into the container 10, and then the insert box connector 121 and the insert box 20 are separated.

[0067] Specifically, when the aforementioned box-loading device 100 is equipped with a detachable second stop block 152, during step S101, the second stop block 152 can be removed from the frame 110 to avoid interference with the box 20. After completing step S107, the second stop block 152 can be reinstalled on the frame 110 to ensure that the box 20 will not detach from the frame 110 during subsequent transport of the box-loading device 100 using the forklift 30.

[0068] Furthermore, during step S109, the second stop block 152 can remain mounted on the rack 110. Then, before proceeding to step S111, the second stop block 152 is removed from the rack 110. After completing step S115, the second stop block 152 can be remounted on the rack 110 to prevent it from being lost.

[0069] When the positioning component 160 is provided on the frame 110, the positioning wheel 164 can be moved away from the push-pull mechanism 120 to the farthest position in the second direction during the above step S101, so as to ensure that the distance between the positioning wheels 164 on both sides is greater than the width of the insertion box 20, and to ensure that the insertion box 20 can be transported to the frame 110 by the push-pull mechanism 120.

[0070] Furthermore, during step S109, before fixing the insert connector 121 to the insert box 20, the positioning wheel 164 can be moved closer to the insert box 20 along the second direction, so that the positioning wheel 164 contacts the insert box 20 and positions the insert box 20. After positioning, the insert box 20 can be fixed to the insert connector 121, so that when the insert box 20 is subsequently pushed into the container 10 using the push-pull mechanism 120, the insert box 20 can be guaranteed to be in the preset position.

[0071] Obviously, those skilled in the art can make various modifications and variations to the embodiments of the present invention without departing from the spirit and scope of the invention. Therefore, if these modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention also intends to include these modifications and variations.
