[0036] The beneficial effects of this utility model are as follows:

[0037] By moving the mobile base to one side of the automated storage and retrieval system (AS / RS) and adjusting the maintenance platform up and down along the Z-axis relative to the mobile base, the maintenance platform is aligned with the exit track of the AS / RS, allowing the four-way shuttle inside the AS / RS to move directly onto the maintenance platform. Simultaneously, locking mechanisms are engaged with the AS / RS to fix the relative position between the mobile base and the AS / RS, ensuring that the mobile base will not slide or move when the four-way shuttle moves onto the maintenance platform, thus guaranteeing a stable movement of the four-way shuttle onto the maintenance platform. The above-mentioned independent design... The four-way shuttle maintenance platform retrieves four-way shuttles from the automated warehouse for maintenance, eliminating the need for maintenance personnel to enter the warehouse. This makes maintenance of the four-way shuttles more convenient and faster, improving efficiency. Furthermore, it prevents other normally operating four-way shuttles from colliding with maintenance personnel, ensuring higher safety. After maintenance, the shuttles can quickly return to the warehouse via the maintenance platform for re-operation, thus guaranteeing high tobacco logistics efficiency. Attached Figure Description

[0051] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0052] Any feature disclosed in this specification, unless specifically stated otherwise, may be replaced by other equivalent or similar features. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features. Throughout this specification, the same reference numerals indicate the same elements.

[0053] To make the technical problem solved by this utility model, the technical solution adopted, and the technical effect achieved clearer, the technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0054] This embodiment proposes a four-way shuttle maintenance platform, such as... Figures 1 to 6 As shown, the four-way shuttle maintenance platform can pick up the four-way shuttle 20 from the automated warehouse 10 for maintenance, making the maintenance of the four-way shuttle 20 more convenient and faster, thus improving maintenance efficiency. In addition, it can prevent other normally transporting four-way shuttles 20 in the automated warehouse 10 from getting out of control and hitting maintenance personnel entering the automated warehouse 10 for maintenance, thus ensuring high maintenance safety.

[0055] It is worth noting that the main improvement in this embodiment lies in the four-way shuttle maintenance platform. Therefore, the specific structure and working principle of the automated warehouse 10 and the four-way shuttle 20 will not be described in detail here. You can refer to the specific structure and working principle of the automated warehouse and the four-way shuttle commonly used in the prior art.

[0056] Specifically, such as Figures 1 to 3As shown, the four-way shuttle maintenance platform includes a movable base 1, a maintenance platform 2, and a locking element 3. The movable base 1 can move along a straight line to one side of the automated warehouse 10. The maintenance platform 2 is raised and lowered along the Z-axis and positioned above the movable base 1. The maintenance platform 2 is used to align with the exit track 102 of the automated warehouse 10 so that the four-way shuttle 20 inside the automated warehouse 10 can be directly moved onto the maintenance platform 2. The locking element 3 is connected to the end of the movable base 1 near the automated warehouse 10. When the maintenance platform 2 is aligned with the exit track 102 of the automated warehouse 10, the locking element 3 locks to the automated warehouse 10.

[0057] like Figure 2 As shown, by locking the locking member 3 to the automated warehouse 10, the relative position between the movable base 1 and the entire four-way shuttle maintenance platform and the automated warehouse 10 can be fixed, ensuring that the movable base 1 will not slide or move during the entire process of the four-way shuttle 20 moving from the automated warehouse 10 to the maintenance platform 2, thereby ensuring that the four-way shuttle 20 moves stably to the maintenance platform 2.

[0058] Compared to related technologies, the four-way shuttle maintenance platform in this embodiment changes the specific maintenance position and method of the four-way shuttle 20. By moving the movable base 1 to one side of the automated warehouse 10 and raising and lowering the maintenance platform 2 relative to the movable base 1 along the Z-axis, the maintenance platform 2 is aligned with the exit track 102 of the automated warehouse 10, so that the four-way shuttle 20 inside the automated warehouse 10 can be directly moved onto the maintenance platform 2. The aforementioned independently set four-way shuttle maintenance platform allows the four-way shuttle 20 inside the automated warehouse 10 to move directly onto the maintenance platform 2. The four-way shuttle 20 can be inspected after being taken out of the warehouse 10, eliminating the need for maintenance personnel to enter the warehouse 10 for maintenance. This makes the maintenance of the four-way shuttle 20 more convenient and faster, improving maintenance efficiency. In addition, it can prevent other normally transporting four-way shuttle 20s in the warehouse 10 from getting out of control and hitting maintenance personnel entering the warehouse 10 for maintenance, thus ensuring high maintenance safety. At the same time, after maintenance, the four-way shuttle 20 can be quickly returned to the warehouse 10 for relocation and use via the maintenance platform 2, thereby ensuring high tobacco logistics efficiency.

[0059] The following is a detailed description of the mobile base 1:

[0060] Specifically, such as Figures 3 to 5As shown, the mobile base 1 includes a mounting plate 11 and rotating wheels 12. A locking element 3 is connected to the end of the mounting plate 11 near the automated storage and retrieval system 10, allowing the locking element 3 to be directly locked onto the automated storage and retrieval system 10. Multiple rotating wheels 12 are rotatably connected to the bottom surface of the mounting plate 11. The rotation of the rotating wheels 12 drives the mounting plate 11 to move linearly, thereby enabling the mobile base 1 to move along a straight line to one side of the automated storage and retrieval system 10, thus driving the entire four-way shuttle maintenance platform to move along a straight line to one side of the automated storage and retrieval system 10. Specifically, the rotating wheels 12 can be omnidirectional wheels, and there are four rotating wheels 12 in total. The four rotating wheels 12 are respectively rotatably mounted at the four corners of the mounting plate 11 to ensure the stability and reliability of the movement of the entire mobile base 1.

[0061] Furthermore, such as Figures 3 to 5 As shown, a first weight-reducing through hole 111 is provided on the mounting plate 11 to reduce the weight of the mounting plate 11, thereby ensuring the lightweight design of the entire four-way shuttle maintenance platform and facilitating easy and quick movement of the entire four-way shuttle maintenance platform. Here, the specific shape and actual number of the first weight-reducing through holes 111 are not limited.

[0062] Specifically, such as Figures 1 to 6 As shown, the end of the mounting plate 11 away from the automated storage and retrieval system 10 is connected to a push handle 112. That is, the locking member 3 and the push handle 112 are disposed opposite to each other on the mounting plate 11 to avoid mutual interference between the locking member 3 and the push handle 112. Furthermore, the movable base 1 can be moved quickly by holding and pushing the push handle 112, making the pushing operation of the movable base 1 simpler and less strenuous.

[0063] The locking component 3 is described in detail below:

[0064] Specifically, such as Figures 3 to 5As shown, the locking component 3 includes a support rod 31, a locking claw 32, a connecting bolt 33, and a fixing nut. One end of the support rod 31 is connected to the end of the mounting plate 11 near the automated storage and retrieval system 10. The locking claw 32 is connected to the other end of the support rod 31. The connecting bolt 33 passes through the support rod 31 and the locking claw 32. When the connecting bolt 33 is rotated, the connecting bolt 33 can synchronously drive the locking claw 32 to rotate relative to the support rod 31, so that the locking claw 32 can rotate to the position of the crossbar 101 of the automated storage and retrieval system 10, and the locking claw 32 hooks onto the crossbar 101, thereby locking the locking component 3 onto the automated storage and retrieval system 10. Then, the fixing nut is threaded onto the connecting bolt 33 to limit the rotation of the connecting bolt 33, ensuring the stability of the locking claw 32 at the hook position, and thus ensuring the locking reliability between the locking component 3 and the automated storage and retrieval system 10. Here, the specific shape of the locking claw 32 is not limited, as long as it can stably lock onto the crossbar 101 of the three-dimensional library 10.

[0065] Furthermore, such as Figures 3 to 5 As shown, at least two locking elements 3 are provided, and the at least two locking elements 3 are disposed opposite each other at the same end of the mounting plate 11, so that they can simultaneously engage with the crossbar 101 through the locking claws 32 of the at least two locking elements 3, thereby better ensuring the locking reliability between the entire four-way shuttle maintenance platform and the automated warehouse 10. In this embodiment, two locking elements 3 are connected to the mounting plate 11. Here, the specific number of locking elements 3 is not limited.

[0066] The following is a detailed description of the maintenance platform 2:

[0067] Specifically, such as Figures 1 to 5As shown, the maintenance platform 2 includes a support plate 21 and baffles 22. The top surface of the support plate 21 has two opposing sliding rails 211, along which the four-way shuttle 20 can move. The sliding rails 211 can be aligned with the exit rail 102, allowing the four-way shuttle 20 within the automated warehouse 10 to move directly onto the sliding rails 211. Along the direction perpendicular to the movement of the four-way shuttle 20, baffles 22 are provided on opposite sides of the support plate 21 to prevent… The baffle 22 interferes with the movement of the four-way shuttle 20 onto the sliding track 211, thereby ensuring that the four-way shuttle 20 in the automated storage and retrieval system 10 can smoothly move onto the sliding track 211 of the support plate 21. The baffle 22 is used to limit and stop the four-way shuttle 20 on the support plate 21, so as to prevent the four-way shuttle 20 from derailing or even falling off the support plate 211 when moving on the sliding track 211, thus ensuring that the four-way shuttle 20 moves along the sliding track 211. Specifically, the support plate 21 and the baffle 22 can be an integral structure; the baffle 22 can be an L-shaped plate, so that the L-shaped plate can better provide a limiting and stopping effect for the four-way shuttle 20 on the support plate 21.

[0068] Furthermore, such as Figures 1 to 5 As shown, the support plate 21 is provided with multiple second weight-reducing through holes 212 to reduce the weight of the support plate 21, thereby better ensuring the lightweight design of the entire four-way shuttle maintenance platform and further facilitating easy and quick movement of the entire four-way shuttle maintenance platform. Here, the specific shape and actual number of the second weight-reducing through holes 212 are not limited.

[0069] The following is a detailed description of the lifting assembly 4:

[0070] Specifically, such as Figures 3 to 5 As shown, the four-way shuttle maintenance platform also includes a lifting assembly 4. The two ends of the lifting assembly 4 are connected to the mounting plate 11 and the support plate 21. The lifting assembly 4 is used to drive the support plate 21 to move up and down along the Z-axis relative to the mounting plate 11, so that the sliding track 211 of the support plate 21 is aligned or misaligned with the exit track 102 of the automated warehouse 10.

[0071] Furthermore, such as Figures 3 to 5As shown, the lifting assembly 4 includes a hydraulic jack 41 and two sets of lifting rod assemblies 42; wherein, the fixed end of the hydraulic jack 41 is connected to the mounting plate 11; the two sets of lifting rod assemblies 42 are arranged opposite to each other, and each lifting rod assembly 42 includes two lifting rods 421 hinged in the middle, the top end of the lifting rod 421 is rotatably connected to the support plate 21, and the bottom end of the lifting rod 421 is rotatably connected to the mounting plate 11. The driving end of the hydraulic jack 41 is drivenly connected to the two lifting rods 421 in one set of lifting rod assemblies 42. The hydraulic jack 41 is used to drive the top ends of the two lifting rods 421 in one set of lifting rod assemblies 42 to move closer or further apart, so that the lifting rods 421 drive the support plate 21 to move up and down along the Z-axis.

[0072] By setting up hydraulic jacks 41 and two sets of lifting rods 42 that work together, on the one hand, the stability and reliability of the support plate 21 rising and falling along the Z-axis can be ensured by the two sets of lifting rods 42; on the other hand, the cost of the entire lifting assembly 4 is lower, the structure is simpler, the layout is more reasonable, and the weight of the entire four-way shuttle maintenance platform can be further reduced.

[0073] Furthermore, such as Figure 5 As shown, a first mounting groove 213 is recessed on the bottom end face of the support plate 21, and a first connecting rod 214 is connected in the first mounting groove 213. The top end of the lifting rod 421 is rotatably connected to the first connecting rod 214. At the same time, a second mounting groove 113 is recessed on the inner side wall of the first weight-reducing through hole 111 of the mounting plate 11, and a second connecting rod 114 is connected in the second mounting groove 113. The bottom end of the lifting rod 421 is rotatably connected to the second connecting rod 114. This arrangement ensures that the lifting rod 421, the support plate 21, and the mounting plate 11 are arranged in a more reasonable and compact manner, and that there is no installation interference between the three. It also ensures that the lifting rod 421 can effectively drive the lifting of the support plate 21.

[0074] Specifically, such as Figures 3 to 5As shown, the lifting assembly 4 also includes a foot pedal 43 and a linkage button; one end of the foot pedal 43 is linked to the hydraulic jack 41, and the other end of the foot pedal 43 extends upwards to the outside of the mounting plate 11 to avoid interference between the mounting plate 11 and the push handle 112 and the foot pedal 43, thus facilitating direct stepping on the foot pedal 43; when the foot pedal 43 is stepped on, it can link the hydraulic jack 41, causing the hydraulic jack 41 to drive the two opposing lifting rods 421 to move closer together by a certain distance, thereby enabling the support plate 21 to rise along the Z-axis via the lifting rods 421. The first distance; pressing the foot pedal 43 again will raise the support plate 21 by the first distance along the Z-axis; the linkage button is connected to the hydraulic jack 41; when the linkage button is pressed once, it will activate the hydraulic jack 41, causing the hydraulic jack 41 to drive the two opposing lifting rods 421 away from each other by a certain distance, thereby allowing the support plate 21 to descend by the second distance along the Z-axis through the lifting rods 421; pressing the linkage button again will lower the support plate 21 by the second distance along the Z-axis; thus, the support plate 21 can be raised and lowered relative to the mounting plate 11 along the Z-axis. The specific values ​​of the first and second distances are not limited here and need to be determined according to the specific lifting requirements of the support plate 21.

[0075] It is worth noting that the hydraulic jack 41, foot pedal 43, and linkage button are all common structures in the prior art. Furthermore, the linkage working principle between the foot pedal 43 and the linkage button and the hydraulic jack 41 can be referred to the linkage working principle of common hydraulic jacks in the prior art. Here, the specific linkage working principle between the hydraulic jack 41, the foot pedal 43, and the linkage button will not be described in detail.

[0076] The following is a detailed description of headspace component 5:

[0077] Specifically, such as Figure 6 As shown, the four-way shuttle maintenance platform also includes a headspace assembly 5. One end of the headspace assembly 5 is connected to the mounting plate 11, and the other end of the headspace assembly 5 can be connected to one side of the four-way shuttle 20. When the support plate 21 descends along the Z-axis, the headspace assembly 5 can support and lift the entire four-way shuttle 20, so that the four-way shuttle 20 can be suspended in the air by the headspace assembly 5, so that the four-way shuttle 20 is completely separated from the support plate 21. That is, the top, bottom and four sides of the four-way shuttle 20 can be seen directly, which facilitates three-dimensional maintenance of the four-way shuttle 20 and improves the convenience and efficiency of maintenance.

[0078] Furthermore, such as Figure 6As shown, multiple headspace components 5 are provided, and these components 5 are evenly distributed on the outer periphery of the support plate 21 where the baffle 22 is not located. On one hand, this avoids placing the headspace components 5 on the side with the baffle 22, thus preventing interference between the baffle 22 and the headspace components 5. On the other hand, multiple headspace components 5 can simultaneously support the suspension of the four-way shuttle 20, ensuring the stability of the support for the four-way shuttle 20, which in turn helps ensure the stability and reliability of subsequent maintenance of the four-way shuttle 20. In this embodiment, four headspace components 5 are provided, with two headspace components 5 positioned opposite each other at one end of the mounting plate 11, and the other two headspace components 5 positioned opposite each other at the other end of the mounting plate 11. The specific number of headspace components 5 is not limited here.

[0079] Specifically, when the four-way shuttle 20 moves to the sliding track 211 of the support plate 21 within the automated storage and retrieval system 10, the support plate 21 moves upward along the Z-axis, so that the top surface of the support plate 21 is higher than the top surface of the headspace assembly 5. This ensures that the headspace assembly 5 does not obstruct the four-way shuttle 20 from moving to the sliding track 211 of the support plate 21, thus ensuring that the four-way shuttle 20 moves smoothly to the sliding track 211 of the support plate 21. When the headspace assembly 5 needs to suspend and support the four-way shuttle 20, the support plate 21 can be moved downward along the Z-axis to make the position of the four-way shuttle 20 correspond to that of the headspace assembly 5, and then the headspace assembly 5 can be connected to one side of the four-way shuttle 20 to suspend and support the four-way shuttle 20.

[0080] Furthermore, the headspace assembly 5 can be detachably connected to the mounting plate 11. When the four-way shuttle 20 in the automated storage and retrieval system 10 moves to the sliding track 211 of the support plate 21, the headspace assembly 5 can be removed from the mounting plate 11 first to ensure that the four-way shuttle 20 moves smoothly to the sliding track 211 of the support plate 21. Then, the headspace assembly 5 can be installed back onto the mounting plate 11.

[0081] Specifically, such as Figure 6 As shown, the headroom assembly 5 includes a top rod 51 and a fastening bolt 52; wherein, the bottom end of the top rod 51 is connected to the outer side of the mounting plate 11, and the top rod 51 is located outside the push handle 112 to avoid mutual interference between the top rod 51 and the push handle 112; and the gap of the top rod 51 is located outside the support plate 21 to avoid interference of the top rod 51 on the lifting and lowering of the support plate 21 along the Z-axis; the fastening bolt 52 is rotatably located at the top end of the top rod 51.

[0082] Specifically, when the fastening bolt 52 is rotated in the forward direction, the fastening bolt 52 can pass through the top rod 51 and be threaded onto one side of the four-way shuttle 20, such as... Figure 6As shown; when the fastening bolt 52 is rotated in the opposite direction, the fastening bolt 52 can be unscrewed from one side of the four-way shuttle 20 and extended back into the top rod 51, so as to avoid the fastening bolt 52 protruding relative to the top rod 51 and affecting the four-way shuttle 20 on the support plate 21.

[0083] Furthermore, such as Figure 6 As shown, the top of the top rod 51 is provided with an open slot 511, and the fastening bolt 52 can be horizontally inserted into the open slot 511 along its length. The open slot 511 is used to limit the fastening bolt 52, and the fastening bolt 52 can be horizontally pulled in a straight line towards or away from the four-way shuttle 20 within the open slot 511. Furthermore, a threaded hole is provided on the side of the four-way shuttle 20, and the fastening bolt 52 can pass through the open slot 511 and be screwed into the threaded hole, thereby ensuring the stability of the connection between the fastening bolt 52 and the four-way shuttle 20.

[0084] The specific working process of the four-way shuttle maintenance platform in this embodiment is as follows:

[0085] First, grasp and push the push handle 112 to rotate the rotating wheel 12 and drive the mounting plate 11 to move linearly, so as to move the entire movable base 1 to one side of the automated warehouse 10; then, use the hydraulic jack 41 to drive the top ends of the two lifting rods 421 in a set of lifting rods 42 to move together, so that the lifting rods 421 drive the support plate 21 to move upward along the Z-axis until the support plate 21 is horizontally aligned with the exit track 102 of the automated warehouse 10. At this time, the sliding track 211 of the support plate 21 is correspondingly flush with the exit track 102.

[0086] Then, rotate the connecting bolt 33, causing the connecting bolt 33 to synchronously drive the locking claw 32 on it to rotate relative to the support rod 31, so that the locking claw 32 rotates to the position of the crossbar 101 of the automated storage 10 and the locking claw 32 hooks onto the crossbar 101; and tighten the fixing nut threaded onto the connecting bolt 33 to limit the continued rotation of the connecting bolt 33; thereby locking the locking member 3 onto the automated storage 10.

[0087] Then, the four shuttle cars in the automated storage and retrieval system 10 are manually moved onto the support plate 21 using a remote control, or the brakes on the four shuttle cars are released and then manually pushed onto the support plate 21 so that the four shuttle cars are completely placed on the support plate 21. At this time, the top surface of the support plate 21 is higher than the top surface of the top rod 51 to ensure that the top rod 51 and the fastening bolt 52 will not obstruct the movement of the four-way shuttle car 20 onto the sliding track 211 of the support plate 21.

[0088] Finally, the support plate 21 is moved downward along the Z-axis so that the position of the four-way shuttle 20 corresponds to that of the fastening bolt 52; then the fastening bolt 52 is rotated in the forward direction so that it passes through the top rod 51 and is threaded into the threaded hole on one side of the four-way shuttle 20; at this time, the four-way shuttle 20 is connected and supported by four fastening bolts 52, so that the top, bottom and four sides of the four-way shuttle 20 are clearly visible, so as to perform three-dimensional inspection of the four-way shuttle 20.

[0089] The four-way shuttle maintenance platform in this embodiment improves the convenience and efficiency of maintenance by taking the four-way shuttle 20 out of the automated warehouse 10 for maintenance, while ensuring high maintenance safety. At the same time, the locking component 3 ensures the stability of the connection between the entire four-way shuttle maintenance platform and the automated warehouse 10. Furthermore, the entire four-way shuttle maintenance platform has a simple structure, low cost, and light weight.

[0090] In this embodiment, the four-way shuttle maintenance platform is equipped with a top-mounted assembly 5 including a top rod 51 and fastening bolts 52. This allows the four-way shuttle 20 to be suspended in the air without interfering with its movement onto the support plate 21, facilitating three-dimensional maintenance of the four-way shuttle 20 without increasing the structural complexity of the entire four-way shuttle maintenance platform.
