[0042] like Figures 1 to 11 As shown, this embodiment provides a multi-layer modular movable rack that can be used in warehouses to store various types of large materials, meeting the needs of efficient management of complex materials in non-standard manufacturing industries. For example, the multi-layer modular movable rack of this embodiment can be used to store bulk materials such as steel for non-standard sewage sludge treatment equipment.

[0043] Specifically, the multi-layer modular movable shelf includes a frame body 100 , a connecting frame 200 , a driving frame 300 , a first transmission assembly 400 and a second transmission assembly 500 .

[0044] The frame 100 mainly includes a vertical frame 110, a support frame 120, a movable frame 130 and a motion mechanism 140. The vertical frame 110 is arranged vertically, for example, it can be arranged substantially perpendicular to the ground. In a frame 100, the number of the support frames 120, the movable frame 130 and the motion mechanism 140 is the same and there are at least two of them, forming at least two material placement spaces on the frame 100, facilitating the separate placement of at least two types of materials. At least two support frames 120 are arranged on the vertical frame 110 in an aligned manner, forming a support structure arranged in layers up and down. Each support frame 120 is provided with a movable frame 130 and a motion mechanism 140, that is, the support frame 120, the movable frame 130 and the motion mechanism 140 are respectively arranged in a one-to-one correspondence. The movable frame 130 is connected to the support frame 120 by the motion mechanism 140, which enables the movable frame 130 to move relative to the support frame 120 along a first horizontal direction, which can be substantially horizontal.

[0045] The number of racks 100 can be multiple, such as two, three, four, or five, depending on the length of the materials to be placed, such as steel. The connecting rack 200 is used to connect the multiple racks 100 arranged along a second horizontal direction, which is perpendicular to the first horizontal direction. The mobile racks 130 located at the same height on the multiple racks 100 connected by the connecting rack 200 can be used to collectively place materials of a certain length, such as steel. Materials of a certain length can be placed on the multiple mobile racks 130.

[0046] The drive frame 300 is disposed on one side of an outer frame of the plurality of frames 100, i.e., the drive frame is located outside the front and rear ends of the plurality of arranged frames 100. The drive frame 300 includes a drive assembly 310, which is used to drive the motion mechanism 140 to move, thereby moving the movable frame 130.

[0047] The first transmission assembly 400 connects the driving assembly 310 and the motion mechanism 140 of the outer frame, thereby transmitting the motion of the driving assembly 310 to the motion mechanism 140 .

[0048] The second transmission assembly 500 connects the motion mechanisms 140 of two adjacent frames 100, so that the motion mechanisms 140 of the adjacent frames 100 can move synchronously, so that multiple mobile frames 130 located at the same height on multiple frames 100 can move synchronously, and together form a placement space for placing materials of a certain length.

[0049] When the multi-layer modular movable shelf of this embodiment is working, the driving component 310 receives external power and drives the motion mechanism 140 of the outer frame to move through the first transmission component 400. The motion mechanism 140 of the outer frame drives the motion mechanism 140 of the remaining frames 100 to move through the second transmission component 500, thereby realizing the movement of a group of mobile frames 130, which is convenient for putting in and taking out a kind of material. When storing materials, the driving component 310 does not work, and the mobile frames 130 are kept retracted into the support frame 120. Similarly, the movement of another group of mobile frames 130 can be realized by the above steps, which is convenient for putting in and taking out another kind of material, and realizing the separate storage and placement of multiple materials. With the above structure, different materials can be placed in different areas using the space in the vertical direction, which is conducive to saving material storage space, and the driving component 310 of the same driving frame 300 is used to realize the movement of the mobile frames 130 on each frame 100, which is convenient to operate.

[0050] In some examples, the stand 110, support frame 120, mobile frame 130, etc. can be made of existing standardized steel profiles and connected by riveting and welding. The production raw materials are easy to obtain and the cost is low, which is conducive to the production of standardized modules.

[0051] In some examples, the drive frame 300 includes a centralized operating area 320, which can be a preset bounded or unbounded area on the surface of the drive frame 300. The drive assembly 310 includes a sprocket assembly, the number of which is less than or equal to the number of motion mechanisms 140 in one frame 100, and the sprocket assembly is used to connect with the motion mechanism 140. The sprocket assembly includes a first sprocket 311, a second sprocket 312, and a chain 313. The first sprocket 311 corresponds to the position of the motion mechanism 140, for example, the first sprocket 311 and the motion mechanism 140 can be arranged at the same height, and the first sprocket 311 is connected to the first transmission assembly 400 via a first rotating shaft 314. The first transmission assembly 400 can be, for example, a circular transmission rod, which transmits the circumferential rotation of the first sprocket 311 to the motion mechanism 140. The second sprocket 312 corresponds to the centralized operation area 320. A second rotating shaft 315 is connected to the second sprocket 312, extending from the centralized operation area 320. This allows the second rotating shaft 315 to be rotated within the centralized operation area 320 to input power. A chain 313 connects the first sprocket 311 and the second sprocket 312, allowing the second sprocket 312 to drive the first sprocket 311. This structure, through the sprocket assembly, centralizes the driving power input of the mobile racks 130 at different height positions into the same area, facilitating convenient operation of each group of mobile racks 130 within the same area.

[0052] In some examples, the diameter of the first sprocket 311 is larger than the diameter of the second sprocket 312 , thereby more finely controlling the movement of the moving frame 130 .

[0053] In some examples, the centralized operation area 320 is located in an area 1 to 2 meters above the bottom of the multi-layer modular movable shelf, so as to facilitate operators of average height to input driving power.

[0054] In some examples, at least one first sprocket 311 is arranged corresponding to the motion mechanism 140 located at the top of the stand 110, that is, the motion mechanism 140 of at least the mobile frame 130 located at the highest point is driven by a sprocket assembly, avoiding the need to climb high for power input.

[0055] In some examples, at least one first sprocket 311 is arranged corresponding to the motion mechanism 140 located at the bottom of the stand 110, that is, the motion mechanism 140 of at least the lowest movable frame 130 is driven by a sprocket assembly, avoiding the need for power input.

[0056] In some examples, the number of sprocket assemblies is equal to the number of motion mechanisms 140 in a frame 100, that is, the sprocket assemblies of all motion mechanisms 140 in the frame 100 are concentrated in the centralized operation area 320 for operation, making operation more convenient.

[0057] In some examples, the centralized operating area 320 is disposed between two moving mechanisms 140 located in the middle in the vertical direction, so that the number of sprocket assemblies above and below the centralized operating area 320 is equal, which is beneficial for reducing the size of the drive frame 300.

[0058] In some examples, the drive assembly 310 includes a first sprocket 311 and multiple sprocket assemblies arranged above the centralized operating area 320. The multiple sprocket assemblies are staggered in the horizontal direction, for example, they can be staggered in the axial direction parallel to the first sprocket 311 or staggered in the axial direction perpendicular to the first sprocket 311 to avoid interference.

[0059] In some examples, the drive assembly 310 includes a first sprocket 311 and multiple sprocket assemblies arranged below the centralized operating area 320. The multiple sprocket assemblies are staggered in the horizontal direction, for example, they can be staggered in the axial direction parallel to the first sprocket 311 or staggered in the axial direction perpendicular to the first sprocket 311 to avoid interference.

[0060] In some examples, the second rotating shaft 315 is used to connect to the handle 316 or an electric device to achieve power input.

[0061] In some examples, at least two support frames 120 are disposed opposite each other in a frame 100 and extend from opposite sides of the frame 100 along a first horizontal direction, thereby utilizing the space on both sides of the frame 100. The motion mechanisms 140 on the two opposing support frames 120 are adjacent and staggered toward the drive frame 300, for example, in a horizontal or vertical direction, to facilitate separate control of the movable frames 130 on the two opposing support frames 120.

[0062] In some examples, the drive assembly 310 includes two sprocket assemblies corresponding to the motion mechanisms 140 on the two relatively arranged support frames 120, and there is a gap between the two sprocket assemblies in the axial direction parallel to the first sprocket 311, and the projections of the two sprocket assemblies in the axial direction parallel to the first sprocket 311 partially overlap, thereby reducing the size of the drive frame 300.

[0063] In some examples, the motion mechanism 140 includes a gear 141, a rack 142, a roller 143, a track 144, and a slider 145. The gear 141 is provided on the support frame 120 and connected to the first transmission assembly 400 or the second transmission assembly 500. The rack 142 is provided on the movable frame 130. The rack 142 cooperates with the gear 141 to convert rotation into linear movement of the movable frame 130. The track 144 is provided on one of the support frame 120 and the movable frame 130, and the slider 145 is provided on the other of the support frame 120 and the movable frame 130. The roller 143 is provided on the slider 145 or the track 144. The track 144 and the slider 145 cooperate through the roller 143 to achieve stable and convenient movement of the movable frame 130.

[0064] In some examples, the multi-layer modular movable rack further includes a bottom frame 600, which is used to connect at least two connecting racks 200 connected along a first horizontal direction, connecting multiple rows of connecting racks 200 into a whole, and preventing the connecting racks 200 from moving. The distance between the support frames 120 of two adjacent connecting racks 200 is greater than the maximum distance that the movable rack 130 can move out of the support frame 120, and is less than or equal to twice the maximum distance. Using this distance allows a group of movable racks 130 between two connecting racks 200 to move out, thus saving space.

[0065] In some examples, the distance between two adjacent support frames 120 in the vertical direction is equal, which facilitates the placement of various materials according to actual needs.

[0066] In some examples, there are at least three frames 100 arranged along the second horizontal direction, and the distance between adjacent frames 100 is the same. The connecting frame 200 includes a crossbar 210 and a reinforcing bar 220. The crossbar 210 connects adjacent vertical frames 110 in the horizontal direction. The crossbars 210 have the same length to facilitate standardization. The reinforcing bar 220 is connected between adjacent vertical frames 110 at an angle relative to the crossbar 210 to improve the connection strength.

[0067] In some examples, the multi-layer modular movable shelf also includes a top rack 700, which is arranged on the top of the vertical rack 110. The projection of the top rack 700 in the vertical direction is less than or equal to the projection of the support rack 120 in the vertical direction. The top rack 700 can also be used to place materials, and when the mobile rack 130 moves out from the support rack 120, the top rack 700 will not block the mobile rack 130.

[0068] In some examples, the mobile frame 130 includes a base plate 131 and a first baffle 132 and a second baffle 133 connected to the base plate 131 and arranged opposite to each other in the first horizontal direction. The mobile frame 130 forms a bracket for supporting materials of a certain length to prevent the materials from moving in the first horizontal direction.

[0069] In some examples, the size of the bottom plate 131 in the first horizontal direction is larger than the size of the bottom plate 131 in the second horizontal direction. Since multiple mobile racks 130 jointly support materials of a certain length, a single bottom plate 131 may have a smaller width.

[0070] In some examples, the drive frame 300 is located outside the outer frame along the second horizontal direction to facilitate transmission. The drive frame 300 also includes a support frame 350 disposed opposite to the drive frame 350 and a cover plate 330 connected to the support frame 350. The support frame 350 and the cover plate 330 enclose a space for accommodating the drive assembly 310. The cover plate 330 is easily opened for maintenance of the drive assembly 310. The drive assembly 310 can be mounted on the support frame 350 via a bearing 340 to enable rotation of the sprocket assembly.

[0071] Finally, it should be emphasized that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
