[0023] Embodiments of the present disclosure will be described in more detail with reference to the drawings. While certain embodiments of the present disclosure are shown in the drawings, it is understood that the present disclosure can be embodied in various forms and should not be interpreted as being limited to the embodiments set forth herein, but rather, these embodiments are provided for more complete and thorough understanding of the present disclosure. It is understood that the drawings and embodiments of the present disclosure are for exemplary purposes only and are not intended to limit the scope of protection of the present disclosure.

[0024] It should be noted that the titles of any sections / subsections provided herein are not limiting. Various embodiments are described throughout this document, and any type of embodiment can be included under any section / subsection. Furthermore, embodiments described in any section / subsection can be combined with any other embodiment described in the same section / subsection and / or a different section / subsection in any manner.

[0025] In the description of embodiments of the present disclosure, the term "includes" and its derivatives, such as "including," should be understood in an open, inclusive sense, that is, "including, but not limited to." The term "based on" should be understood as "based at least in part on." The term "one embodiment" or "an embodiment" should be understood as "at least one embodiment." The term "some embodiments" should be understood as "at least some embodiments." Other explicit or implicit definitions can also be included below. The terms "first," "second," etc. can refer to different or the same objects. Other explicit and implicit definitions can also be included below.

[0026] As briefly mentioned above, in a conventional multi-layer shuttle car stereoscopic warehouse, shelves are arranged in rows in the stereoscopic warehouse, and each row of shelves includes multiple layers of storage layers arranged in the height direction (i.e., the gravity direction). The storage layers extend in the extension direction, objects are placed in the corresponding pockets of the storage layers, and the taking and placing of goods are completed by the shuttles on the shelves.

[0027] To facilitate personnel to handle faults in the shelf, some shelves are arranged with maintenance platforms at the tail end (also referred to as the end of the shelf extension direction). The maintenance platform is connected to the ground through a staircase. Maintenance personnel can climb to the corresponding maintenance platform through the staircase and maintain one or more storage layers within the height of the platform. However, such a layout of the shelf also makes the shelf far away from the load platform of the maintenance mechanism, and it is difficult for the shuttle vehicle of the shelf to be lowered for maintenance.

[0028] The fast-mounting track for the shelf maintenance mechanism and the shelf maintenance mechanism provided according to the present disclosure are used to solve or at least partially solve the above-mentioned problems and other potential problems in the prior art. According to some embodiments of the present disclosure, the fast-mounting track for the shelf maintenance mechanism is arranged at the tail end of the track of the shelf of the multi-layer shuttle vehicle stereoscopic warehouse and is located between the track and the maintenance hoist. Thus, the fast-mounting track can connect the track and the fast-mounting track, so that the shuttle vehicle of the track can be moved to the maintenance hoist via the fast-mounting track, and then the maintenance hoist can move the shuttle vehicle to the ground for maintenance. In this way, the efficiency of the maintenance personnel in maintaining the shelf is improved.

[0029] Figure 1 A simple schematic diagram of a working scene of a shelf maintenance mechanism according to some embodiments of the present disclosure is shown. As shown in Figure 1 In a multi-layer shuttle vehicle stereoscopic warehouse system, the track 2 includes a plurality of arrangement layers arranged along a height direction parallel to the direction of gravity, and each arrangement layer extends along an extension direction perpendicular to the height direction. The track 2 is arranged with a maintenance platform 21 at one end in the extension direction, and maintenance personnel can climb to the maintenance platform 21 by a staircase or the like and maintain the storage layer at the corresponding height of the track 2.

[0030] Figure 2 A schematic diagram of the overall structure of a shelf maintenance mechanism according to some embodiments of the present disclosure is shown. As shown in Figure 2 The track 2 maintenance mechanism includes a maintenance hoist 1 arranged on the side of the maintenance platform 21 away from the track 2, and a fast-mounting track arranged between the maintenance hoist 1 and the track 2. The fast-mounting track is adapted to connect the storage layer of the track 2 and the maintenance hoist 1, so that the shuttle vehicle of the track 2 can be moved to the maintenance hoist 1 through the fast-mounting track.

[0031] The maintenance hoist 1 includes four columns 11 arranged on the ground and adapted to extend along the height direction. The four columns 11 are slidably connected with a vehicle platform 12. The shuttle vehicle can slide from the storage layer of the track 2 to the vehicle platform 12 through the fast-mounting track, and be lowered to the ground through the sliding of the vehicle platform 12 on the columns 11. In this way, it is convenient for maintenance personnel to maintain the shuttle vehicle.

[0032] In some embodiments, the track 2 maintenance mechanism can further comprise an emergency stop button 8, which can be arranged on the vehicle carrying platform 12. The emergency stop button 8 can be triggered (e.g. pressed) by the maintenance personnel to stop the lifting of the vehicle carrying platform 12.

[0033] Figure 3 A structural diagram of the detection sensor is shown according to some embodiments of the present disclosure. As shown in Figure 2 and Figure 3 In some embodiments, the maintenance hoist 1 further comprises at least one pair of detection sensors 7, which are arranged on a pair of columns 11 close to the track 2 and are adapted to detect whether an object (e.g. part of the body of the maintenance personnel, etc.) passes between the pair of columns 11 during the lifting of the vehicle carrying platform 12 and send a signal indicating the stopping of the lifting of the vehicle carrying platform 12 during the passing of the object. In this way, the safety of the operation of the track 2 maintenance mechanism can be improved. In some embodiments, the maintenance hoist 1 can comprise a plurality of pairs of detection sensors 7, which are arranged on the corresponding columns 11 at intervals in the height direction.

[0034] As shown in Figure 4 A schematic diagram of the connecting rail is shown according to some embodiments of the present disclosure. As shown in Figure 2 and Figure 4 The quick-mounting track comprises a pair of connecting rails 3 arranged between the track 2 and the maintenance hoist 1. The connecting rails 3 extend along the extension direction of the track 2 and the pair of connecting rails 3 are respectively aligned with the columns 11 arranged perpendicularly to the extension direction. The first end of the connecting rail 3 is coupled to the column 11 of the vehicle carrying platform 12, and the second end of the connecting rail 3 opposite to the first end is coupled to the shelf of the track 2. In this way, the connecting rail 3 connects the track 2 and the maintenance hoist 1. The second end of the connecting rail 3 comprises a first tab 321 and a second tab 322 arranged perpendicularly to each other, which respectively extend along the extension direction. During the coupling of the second end of the connecting rail 3 and the track 2, the first tab 321 and the second tab 322 are at least partially inserted into the track 2, thereby improving the accuracy and stability of the connection of the connecting rail 3 and the track 2, so that the shuttle vehicle can slide more smoothly from the track 2 into the connecting rail 3.

[0035] Figure 5 An enlarged view of detail A in Figure 2 is shown according to some embodiments of the present disclosure. As shown in Figure 2 and Figure 5 In some embodiments, the quick-mounting guide rail further comprises a second connecting bolt 6 arranged at the second end of the connecting rail 3, and the second connecting bolt 6 is adapted to, after the first tab 321 and the second tab 322 of the second end are respectively inserted into the track 2 and installed in place, sequentially pass through the second end and the track 2 and threadedly cooperate with the corresponding nuts, so as to fix the track 2 and the connecting rail 3.

[0036] Figure 6 A schematic view of a connector is shown according to some embodiments of the present disclosure. As shown in Figure 2 and Figure 6 In some embodiments, the quick-mount rail further comprises a plurality of connectors 4 coupled to the upright 11 along a height direction of the upright 11 and spaced apart by a predetermined distance along the height direction to match a plurality of storage layers of the rail 2 arranged along the height direction. The first end of the connecting rail 3 can be coupled to the upright 11 through the connector 4. The connecting rail 3 can also be coupled to different connectors 4 on the upright 11 at different heights, thereby matching different storage layers of the rail 2 at different heights.

[0037] In some embodiments, the connector 4 comprises a mounting portion 41, a bending portion 42 coupled to the mounting portion 41, and a fixing portion 43 coupled to the bending portion 42 away from the mounting portion 41. The mounting portion 41 is coupled to a side wall of the upright 11. In some embodiments, a pair of connecting rails 3 is arranged between a pair of uprights 11 for fixing the pair of connecting rails 3, and accordingly, the mounting portion 41 can be arranged on the side wall of the upright 11 facing the corresponding connecting rail 3. The bending portion 42 is arranged on one side of the mounting portion 41 and bent and extended towards the connecting rail 3, and the fixing portion 43 is coupled to one end of the bending portion 42 away from the mounting portion 41 and coupled to the second end of the connecting rail 3.

[0038] In some embodiments, the connecting rail 3 further comprises a supporting portion 44 coupled to the fixing portion 43 and adapted to be supported below the second end of the connecting rail 3 along the height direction during the coupling of the fixing portion 43 to the second end of the connecting rail 3. Thus, the weight of the connecting rail 3 and the shuttle vehicle can be at least partially supported, and the accuracy of the alignment of the connecting rail 3 and the vehicle carrying platform 12 can be improved.

[0039] In some embodiments, the mounting portion 41, the bending portion 42, the fixing portion 43, and the supporting portion 44 can be integrally formed, for example, the mounting portion 41, the bending portion 42, the fixing portion 43, and the supporting portion 44 can be formed by processing a profile material of a predetermined shape through bending or other processes. In some other embodiments, the mounting portion 41, the bending portion 42, the fixing portion 43, and the supporting portion 44 can also be separately formed and connected through welding or other means.

[0040] As shown in Figure 4 and Figure 6As shown, in some embodiments, the connecting rail 3 further comprises a positioning pin 33 arranged on the side of the first end towards the supporting portion 44. Correspondingly, the connecting piece 4 further comprises a positioning hole 45 formed on the side of the supporting portion 44 towards the second end and adapted to allow the positioning pin 33 to be inserted during coupling of the second end of the connecting rail 3 to the connecting piece 4. By cooperation of the positioning pin 33 and the positioning hole 45, pre-positioning of the fixing of the connecting rail 3 and the connecting piece 4 can be provided, thereby facilitating the fixing of the connecting piece 4 and the connecting rail 3.

[0041] In some embodiments, the positioning hole 45 of the supporting portion 44 can be a waist-shaped hole, and the length direction of the cross section of the waist-shaped hole perpendicular to the axis is parallel to the extending direction. During insertion of the positioning pin 33 of the connecting rail 3 into the positioning hole 45, the connecting rail 3 can be adjusted along the extending direction relative to the connecting piece 4, thereby facilitating alignment of the first end of the connecting rail 3 with the vehicle carrying platform 12 and alignment of the second end of the connecting rail 3 with the track 2.

[0042] Referring back to Figure 2 In some embodiments, the quick-mounting track further comprises a first connecting bolt 5 arranged on the first end of the connecting rail 3 and passing through the second end and the fixing portion 43, and the second end and the fixing portion 43 are fixed by cooperation of the first connecting bolt 5 and a nut.

[0043] Through the above description, during maintenance of the shuttle vehicle of the track 2, the second end of the connecting rail 3 can be fixed to the corresponding storage layer of the track 2, and the first end of the connecting rail 3 can be fixed to the connecting piece 4 on the upright column 11 for climbing the storage layer. Thus, the shuttle vehicle can be moved to the vehicle carrying platform through the connecting rail 3 and carried to the ground by the vehicle carrying platform.

[0044] The above has described the implementations of the present disclosure, and the above description is exemplary, not exhaustive, and is not limited to the disclosed implementations. Many modifications and changes are obvious to those skilled in the art without departing from the scope and spirit of the described implementations. The selection of the terms used herein is intended to best explain the principles of the implementations, practical applications, or improvements to the technology in the market, or to enable other ordinary skilled persons in the art to understand the various implementations disclosed herein.
