Description

Technical Field

[0001] This invention relates to the field of automated warehouse technology, specifically to an automated warehouse for the delivery and storage of multi-layer track-type concrete test blocks for pre-curing. Background Technology

[0002] After sampling and molding, concrete test blocks generally require a second surface finishing treatment 4-6 hours after initial setting. Then, the test blocks are pre-cured in their molds. Pre-curing conditions follow national standards consistent with post-molding curing standards: a curing room temperature of 20°C ± 2°C, humidity greater than 95%, and a pre-curing time of 24-48 hours. After the pre-curing period, the blocks are demolded and then placed in the curing room for final curing. Currently, most ready-mixed concrete plants perform concrete test block molding, initial setting, and pre-curing in air-conditioned rooms, where the temperature and humidity generally fail to meet national standards. Furthermore, when producing a large number of concrete test blocks, initial setting and pre-curing are typically done on the floor of the room, resulting in insufficient initial setting and pre-curing times. This severely impacts the quality of the concrete test blocks, and the attribute markings on the blocks cannot be accurately matched, leading to less rigorous final test results and failing to meet the needs of automated production and management of concrete test blocks.

[0003] Therefore, considering the above, the shortcomings of the existing technology are: the initial setting time and pre-curing time are difficult to meet the requirements due to the stacking of concrete test blocks on the ground; and the attribute markings of the concrete test blocks are difficult to match one-to-one, leading to inaccurate subsequent test results. This application proposes a solution to address these issues. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-layer track-type three-dimensional warehouse for the delivery and storage of pre-cured concrete test blocks, which solves the problem of inaccurate subsequent test results caused by the difficulty in matching the stacking and attribute marking of test blocks.

[0005] The objective of this invention can be achieved through the following technical solution: a multi-layer track-type three-dimensional warehouse for the delivery and storage of pre-cured concrete test blocks, comprising a multi-layer warehouse frame and inbound and outbound racks respectively provided on both sides of the multi-layer warehouse frame. Roller shutters are installed on both sides of the multi-layer warehouse frame. A track frame is provided inside the multi-layer warehouse frame, and track plates are arranged in layers inside the track frame. Brackets are symmetrically distributed on the upper side of the track plate corresponding to the track plate. A lifting platform is vertically slidably installed on the outer side of the multi-layer warehouse frame corresponding to the roller shutter. A rotating track disk aligned with the track plate is rotatably installed on the lifting platform. A storage and retrieval trolley for mold boxes is rolled on the rotating track disk. The storage and retrieval trolley has a lifting mechanism for lifting the mold boxes. A constant temperature humidifier for controlling the temperature and humidity inside the warehouse is installed at the upper end of the multi-layer warehouse frame.

[0006] The configuration is further defined as follows: side guide rails for vertical movement of the lifting platform are installed on both sides of the multi-layer warehouse frame; racks are installed in the middle of both sides of the multi-layer warehouse frame; and a drive gear that meshes with the rack is installed at the bottom of the lifting platform via a drive motor.

[0007] The lifting platform is further configured such that a rotary gear ring is installed at the lower end of each rotating track disk, and a motor is installed on the lower side of the lifting platform. The motor drives a rotating gear that meshes with the rotary gear ring.

[0008] The lifting platform is further configured such that a mating panel is vertically provided on the inner side of each rotating track disk at its initial position, and the mating panel is aligned with the track plate at the same horizontal height.

[0009] Further configuration: the bottom of the storage trolley is rotatably provided with a traveling wheel that cooperates with the corner rail on the track plate; a second motor for driving the traveling wheel to rotate is installed on the rear side of the storage trolley; the lifting mechanism is embedded in the top of the storage trolley and is used for lifting the top mold box; the width of the lifting end of the lifting mechanism is less than the distance between a pair of brackets.

[0010] The configuration is further defined as follows: the inbound and outbound racks are vertically arranged on both sides of the multi-layer warehouse rack, and the mold boxes are arranged in the longitudinal position on the inbound and outbound racks and are parallel to the track plate.

[0011] The configuration is further defined as follows: at least two track slabs are distributed on the same layer, and there is a gap between adjacent track slabs.

[0012] Further configuration: barcode scanners and photoelectric sensors are installed at the entry and exit corners of both the inbound and outbound shelves, respectively for monitoring the entry and exit of mold boxes.

[0013] The present invention has the following beneficial effects: 1. This invention addresses the problem of inaccurate subsequent test results caused by the difficulty in matching the stacking and attribute marking of test blocks. It employs a multi-layered, automated warehouse structure for the pre-curing of concrete test blocks. This not only allows for continuous input and output via a lifting platform, enabling the placement of test blocks to be pre-cured into predetermined positions within the automated storage space, but also allows for pre-curing at different times according to the curing requirements of test blocks of different specifications. The entire process solves the problems of substandard environment, chaotic storage, difficulty in attribute traceability, and low automation in traditional concrete test block pre-curing processes, while also ensuring convenient management and adapting to the automated production needs of modern ready-mixed concrete. 2. A multi-layer track-type storage structure is adopted, with at least two track plates on the same layer and reasonable gaps reserved. Compared with traditional flat stacking on the ground, it saves a lot of floor space and can accommodate more mold boxes in the same space, effectively solving the storage pressure when the number of test blocks is large. In addition, the layered track plates of the track frame and the symmetrical support structure form a stable support structure. The precise matching of the trolley's traveling wheels and the angled rails, and the four-bar synchronous action of the lifting mechanism, ensure that the mold box is transferred and stored smoothly without shaking, avoiding structural damage to the test blocks caused by collisions or tilting.

[0017] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. 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 of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0018] Example 1

[0019] To address the problem of inaccurate test results caused by difficulties in matching test block stacking and attribute labeling, the following technical solution is proposed: Reference Figure 1 - Figure 8 As shown, this embodiment of a multi-layer track-type concrete test block pre-curing delivery and storage three-dimensional warehouse includes a multi-layer warehouse frame 1 and an inbound rack 2 and an outbound rack 3 respectively provided on both sides of the multi-layer warehouse frame 1. Roller shutter doors 11 are installed on both sides of the multi-layer warehouse frame 1. A track frame 18 is provided inside the multi-layer warehouse frame 1. Track plates 10 are arranged in layers inside the track frame 18. The track frame 18 is provided with symmetrically distributed brackets 19 at intervals on the upper side of the track plates 10. A lifting platform 4 is vertically slidably installed on the outer side of the multi-layer storage frame 1 corresponding to the roller shutter door 11. A rotating track disk 12, aligned with the track plate 10, is rotatably mounted on the lifting platform 4. A storage trolley 5 for the mold box 7 is rolled on the rotating track disk 12 for entering and exiting the storage. The storage trolley 5 has a lifting mechanism 21 built in it for lifting the mold box 7. A constant temperature humidifier 6 for controlling the temperature and humidity inside the storage is installed at the upper end of the multi-layer storage frame 1. The roller shutter doors 11 on both sides of the multi-layer storage frame 1 receive instructions from the management system and automatically rise when the storage trolley 5 is about to enter or leave the storage body, and automatically fall after the action is completed to ensure the airtightness of the storage body. The constant temperature humidifier 6 installed at the upper end of the multi-layer storage frame 1 continuously monitors and adjusts the temperature and humidity inside the storage body. In conjunction with the airtight function of the roller shutter door 11, it ensures that the storage body always maintains a pre-curing environment that meets national standards and reduces the loss of temperature and humidity. The above-mentioned intelligent control system realizes the standard pre-curing of concrete test blocks to ensure that the requirements of national standards are met.

[0020] Both sides of the multi-layer warehouse frame 1 are equipped with side guide rails 8 for vertical movement of the lifting platform 4. Racks 9 are installed in the middle of both sides of the multi-layer warehouse frame 1. The bottom of the lifting platform 4 is equipped with a drive gear 15 that meshes with the rack 9 via a drive motor. A rotary gear ring 17 is installed at the lower end of each rotating track disk 12 of the lifting platform 4. A motor 14 is installed on the lower side of the lifting platform 4. The motor 14 drives a rotary gear 16 that meshes with the rotary gear ring 17. The lifting mechanism of the lifting platform 4 is as follows: the side guide rails 8 installed on both sides of the multi-layer warehouse frame 1 provide vertical guidance for the lifting platform 4 to prevent deviation during the lifting process; the racks 9 fixed in the middle of both sides of the multi-layer warehouse frame 1 form a meshing transmission structure with the drive gears 15 connected to the drive motor at the bottom of the lifting platform 4; after receiving the floor height command from the management system, the drive motor drives the lifting platform 4 to make a smooth lifting motion along the side guide rails 8 through the precise meshing of the drive gears 15 and the racks 9, which can accurately match the height of any layer of track plate 10 in the warehouse, and realize the transfer and connection of the mold box 7 between different floor heights; The rotation principle of the rotating track disk 12 is as follows: A rotary gear ring 17 is installed at the lower end of each rotating track disk 12 corresponding to the lifting platform 4. The motor 14 on the lower side of the lifting platform 4 drives the rotating gear 16 to mesh with the rotary gear ring 17 to achieve a controllable 90° rotation of the rotating track disk 12. This movement allows the track of the storage and retrieval trolley 5 on the rotating track disk 12 to switch between two states: one is aligned with the longitudinal track of the inbound rack 2 or the outbound rack 3, and the other is aligned with the transverse track of the internal track plate 10. This solves the problem of changing tracks when the inbound rack 2, the outbound rack 3 and the internal track are vertically distributed, and ensures the continuity of the transfer path. The lifting platform 4 is vertically provided with a mating panel 13 on the inner side of the initial position of each rotating track disk 12. The mating panel 13 is aligned with the track plate 10 at the same horizontal height. Both the inbound rack 2 and the outbound rack 3 are equipped with barcode scanners and photoelectric sensors at their respective entry and exit corners for monitoring the entry and exit of mold boxes 7. Relying on the coordination of the management system, barcode scanners, photoelectric sensors, and various power components, the entire process of mold boxes 7 from entry, transfer, storage, pre-curing to exit is automated, eliminating the need for manual handling, placement, and timing, thus significantly reducing labor costs and human error. The smooth operation and rapid response of each component significantly improve the efficiency of large-scale pre-curing of test blocks, meeting the needs of automated production. The barcode scanner reads the QR code twice during the warehousing and outbound processes, enabling a one-to-one binding of the test block attributes with the mold box 7. The management system records information such as the test block's warehousing time, pre-curing cycle, and storage location throughout the process, forming a complete traceability chain. This completely solves the problems of attribute confusion and mark loss caused by traditional ground stacking, ensuring the rigor of the final test results.

[0021] Basic principle: This invention uses a multi-layered storage structure in a three-dimensional warehouse for the pre-curing of concrete test blocks. It not only enables continuous input and output using a lifting platform to place the test blocks to be pre-cured into predetermined positions in the three-dimensional storage space, but also allows for pre-curing at different times according to the curing requirements of test blocks of different specifications. The entire process solves the problems of substandard environment, chaotic storage, difficulty in attribute traceability, and low automation in the traditional pre-curing process of concrete test blocks, while taking into account convenient management and adapting to the automated production needs of modern ready-mixed concrete.

[0022] Example 2

[0023] Reference Figure 3 and Figure 5 - Figure 8 As shown, this embodiment is based on embodiment one, and further optimizes some of its structures, including: the bottom of the storage trolley 5 is rotatably provided with a traveling wheel that cooperates with the upper corner rail of the track plate 10; a motor 20 for driving the traveling wheel to rotate is installed on the rear side of the storage trolley 5; a lifting mechanism 21 is embedded in the top of the storage trolley 5 and is used for lifting the top mold box 7; the width of the lifting end of the lifting mechanism 21 is less than the distance between a pair of brackets 19. The inbound rack 2 and the outbound rack 3 are vertically arranged on both sides of the multi-layer warehouse rack 1. The mold boxes 7 are arranged in the longitudinal position on the inbound rack 2 and the outbound rack 3 and are parallel to the track plate 10.

[0024] Reference Figure 7 , Figure 11 and Figure 12 As shown, the walking and lifting motion principle of the storage trolley 5 is as follows: The walking wheels at the bottom of the storage trolley 5 are precisely matched with the angled rails of the track plate 10. The motor 20 at the rear of the storage trolley 5 provides power to the walking wheels, driving the storage trolley 5 to travel smoothly along the continuous track of the inbound rack 2, the rotating track plate 12, the track plate 10, and the outbound rack 3. The lifting mechanism 21 embedded at the top of the storage trolley 5 adopts a one-to-four reducer structure, which can realize the synchronous vertical extension and retraction of four rods. The width of the lifting end is less than the distance between a pair of brackets 19, ensuring that: ① when picking up materials, the lifting mechanism 21 extends to lift the mold box 7 away from the inbound rack 2 or the bracket 19; ② when releasing materials, the lifting mechanism 21 extends and then retracts to place the mold box 7 stably on the bracket 19 or the outbound rack 3; ③ during the walking process, the lifting mechanism 21 maintains the lifting state to prevent the mold box 7 from shaking and slipping.

[0025] There are at least two track slabs 10 on the same floor, and there is a gap between adjacent track slabs 10. The entire automated warehouse adopts a three-dimensional space storage method, which integrates the pre-curing of concrete test blocks with molds in a space that is easy to quickly transfer and easy to mark attributes, thereby improving the efficiency of pre-curing.

[0026] Example 3

[0027] Reference Figure 1 - Figure 12 As shown, this embodiment combines the technical content of Embodiment 1 and Embodiment 2 to form the following usage method: Step 1, Warehousing Process: After the concrete test block mold box 7 has been finished twice, it is transported to the designated longitudinal position of the warehousing rack 2. After the photoelectric sensor at the corner of the warehousing rack 2 detects that the mold box 7 has arrived, it sends a signal to the automated warehouse management system. The management system instructs the storage trolley 5 to travel along the track of the warehousing rack 2 to the bottom of the mold box 7. The lifting mechanism 21 built into the storage trolley 5 extends and lifts the mold box 7 off the warehousing rack 2. During the lifting process, the barcode scanner on the storage rack 2 reads the QR code on the mold box 7 and uploads the test block attributes, specifications, molding time, pre-curing cycle, etc. to the management system. The management system automatically plans the shortest transfer path and allocates storage positions in the warehouse. The storage trolley 5 carries the mold box 7 to the rotating track disk 12 of the lifting platform 4 at the storage end. The drive motor at the bottom of the lifting platform 4 drives the drive gear 15 to mesh with the rack 9 of the multi-layer warehouse frame 1 and lifts it up and down along the side guide rail 8 to the layer height corresponding to the allocated position. The motor 14 drives the rotating gear 16 to mesh with the rotary gear ring 17, driving the rotating track disk 12 to rotate 90°, so that the travel track of the storage trolley 5 is aligned with the track plate 10 in the warehouse. At this time, the cooperation panel 13 and the track plate 10 remain horizontal and flush to ensure smooth transfer. The roller shutter door 11 on the corresponding side of the multi-layer warehouse frame 1 automatically rises, the storage trolley 5 travels along the track plate 10 to the designated storage position, the lifting mechanism 21 retracts, and the mold box 7 is placed smoothly on the bracket 19 of the track frame 18. The storage trolley 5 returns to the rotating track plate 12 along the original track, the roller shutter door 11 automatically falls, the rotating track plate 12 rotates 90° in the opposite direction to reset, the lifting platform 4 falls back to the initial height, the storage trolley 5 returns to the standby position, the storage is completed, and the test block begins pre-curing with mold. Step 2, Pre-curing process: The constant temperature humidifier 6 at the top of the multi-layer warehouse frame 1 works continuously to adjust the temperature and humidity inside the warehouse in real time, ensuring that the national standard environment of 20°±2° and humidity greater than 95% is always maintained. The three-dimensional warehouse management system records the pre-curing time of each mold box 7 in real time, and marks the demolding time of the test block with different colors through the visual interface, and displays information such as the number of mold boxes 7 in the warehouse and the distribution of empty spaces, so as to realize intelligent monitoring. Step 3, Outbound Process: When the pre-maintenance time of a mold box 7 expires, the management system automatically issues an expiration reminder, instructs the outbound end lifting platform 4 to rise and fall along the side guide rail 8 to the corresponding floor height, the outbound end roller shutter door 11 automatically rises, the storage and retrieval trolley 5 travels along the track plate 10 to the bottom of the mold box 7, the lifting mechanism 21 extends to lift the mold box 7, the storage and retrieval trolley 5 carries the mold box 7 back to the outbound end rotating track plate 12, the roller shutter door 11 automatically falls, the rotating track plate 12 rotates 90° to align the track of the storage and retrieval trolley 5 with the outbound rack 3, and the lifting platform 4 falls back to the initial height; The retrieval trolley 5 travels to the designated position on the outgoing rack 3, the lifting mechanism 21 retracts, and the mold box 7 is placed on the outgoing rack 3. The barcode scanner of the outgoing rack 3 scans the code again to confirm the properties of the test block and sends a signal to the demolding station. The retrieval trolley 5 returns to the standby position of the lifting platform 4, the rotating track disk 12 resets, and the outgoing process is completed.

[0028] In summary, this invention, in conjunction with embodiments one, two and three, utilizes a multi-layered storage structure in a three-dimensional warehouse for the pre-curing of concrete test blocks. This not only enables continuous input and output using a lifting platform to place the test blocks to be pre-cured into predetermined positions within the three-dimensional storage space, but also allows for pre-curing at different times according to the curing requirements of test blocks of different specifications. The entire process can solve the problems of substandard environment, chaotic storage, difficulty in tracing properties and low degree of automation in the traditional pre-curing process of concrete test blocks, while taking into account the convenience of management and adapting to the automated production needs of modern ready-mixed concrete.
