Description

Technical Field

[0001] This invention relates to the field of building materials testing technology, specifically a full-process management system for the transportation, warehousing, curing, and release of concrete test blocks, applicable to the curing and transportation of standard test blocks in testing laboratories or construction units. Background Technology

[0002] Concrete test blocks must undergo standard curing according to regulations after molding. The current national standard GB / T 50081-2019 requires test blocks to be spaced 10-20mm apart on the curing rack. Currently, most laboratories manually place the test blocks one by one onto fixed supports, which presents the following problems: 1. Manual handling is inefficient and labor-intensive, and can easily cause test blocks to chip or break. 2. The curing rack has a fixed layout and low space utilization, making it difficult to cope with scenarios with a large number of test blocks or a small curing room area; 3. The management of test blocks entering and leaving the warehouse is chaotic, making it difficult to achieve first-in-first-out and affecting the consistency of maintenance quality.

[0003] While fully automated maintenance systems exist (such as robotic arm gripping + track conveyor), their high cost (over one million yuan) makes widespread adoption difficult. Therefore, there is an urgent need for a cost-effective, efficient, and standard-compliant solution for the transport and maintenance management of test blocks. Summary of the Invention

[0004] The present invention aims to provide a concrete test block transportation and curing management system and method to solve the problems of low efficiency of manual handling, easy damage to test blocks, insufficient utilization of curing space, and chaotic management in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: In a first aspect, the present invention provides a concrete test block transportation and curing management system, comprising: The maintenance and circulation system adopts a closed-loop track design, and the test blocks are arranged in order of their entry time to achieve first-in-first-out management. The maintenance and handling stacked bracket includes multiple stackable bracket units, each of which includes a load-bearing layer and a limiting layer for supporting and positioning test blocks. Transport and loading / unloading tools are used to move the entire bracket to the curing room or testing room.

[0006] Furthermore, the maintenance and circulation system is a "snake"-style closed-loop track, with newly entered test blocks placed at the head of the track and exiting test blocks taken from the tail. The track is marked with a date unit.

[0007] Furthermore, each layer of the maintenance and handling stacking bracket can accommodate 2-8 sets of test blocks, bear a load of 50-200kg, support stacking of 4-8 layers, and has a total height of 0.9-1.7 meters.

[0008] Furthermore, the bottom of the bracket can be fitted with pulleys for easy pushing; the limiting layer is provided with baffles or slots with adjustable spacing to accommodate test blocks of different sizes.

[0009] Furthermore, the transportation and loading / unloading equipment includes manual forklifts and pallet jacks, enabling fully mechanized operations from loading and unloading to warehousing.

[0010] Furthermore, it is suitable for laboratory environments with more than 50 sets of test blocks entering the warehouse per day and limited curing room area that cannot be expanded.

[0011] Secondly, the present invention provides a method for curing and managing concrete test blocks based on the above-mentioned system, characterized by comprising the following steps: S1: Manually load the demolded test block into the curing and handling stacking bracket in one go; S2: Use transport and loading / unloading tools to transport the entire tray carrying the test blocks to the curing room; S3: Through the maintenance and circulation system, the brackets are put into a closed loop for maintenance according to the order of their entry into the warehouse; S4: After the curing period, remove the corresponding bracket from the end of the track and transport it to the testing room; S5: Remove the test block from the bracket for testing.

[0012] Compared with the prior art, the beneficial effects of the present invention are: 1. Curing and Transfer System: The system adopts a "snake"-like closed-loop track design, with all curing racks connected end-to-end to form a circular flow. Newly received test blocks are placed at the head of the track, and outgoing test blocks are taken from the tail. The track is marked with daily markers to achieve orderly transfer of test blocks according to their age, ensuring first-in-first-out and maximizing the use of curing rack space.

[0013] 2. Maintenance and Handling Stacking Bracket: This modular design includes a load-bearing layer and a positioning layer. The bracket supports multi-layer stacking, with each layer holding 2-8 sets of test blocks, bearing a load of 50-200kg. After stacking 4-8 layers, the total height is only 0.9-1.7 meters, significantly lower than traditional brackets (1.5-1.8 meters). The positioning layer can be equipped with adjustable baffles or slots to ensure the spacing between test blocks meets the 10-20mm standard.

[0014] 3. Transportation and loading / unloading equipment: A combination of manual forklifts and pallet jacks is used to achieve fully mechanized operation of the entire process of test blocks from palletizing, loading onto trucks, unloading, warehousing, to delivery. Only one manual handling is required during palletizing, greatly reducing the risk of damage. This system is suitable for environments including: daily test block intake of more than 50 sets; small curing room area that cannot be expanded; and situations requiring long-distance or multiple transfers.

[0016] 1. Maintenance and handling stacked brackets; 3. Load-bearing layer; 4. Limiting layer. Detailed Implementation

[0017] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be emphasized that the embodiments described herein are only used to illustrate the working principle of the present invention and do not constitute any limitation on the scope of protection.

[0018] See Figure 1 The core of this invention lies in constructing an integrated system of "modular handling, closed-loop circulation, and mechanized operation." Its workflow and technical features are as follows: First, at the test block demolding point (construction site or laboratory), the operator neatly stacks the test blocks in one go on the curing and handling stacking bracket 1 (see...). Figure 3 The bracket's limiting layer 4, through preset or adjustable slots, ensures that each set of test blocks automatically maintains a standard spacing of 10-20mm, eliminating errors caused by manual placement. The load-bearing layer 3 adopts a mesh or strip-shaped reinforcing structure to reduce its own weight while ensuring support strength.

[0019] Next, using transport and loading tools (manual forklifts or pallet jacks), the loaded trays are lifted and transferred to the transport vehicle. Upon arrival at the curing room, the trays are unloaded using the same tools and can be immediately stacked in multiple layers (usually 4-8 layers). Due to the standardized design and stable structure of the trays, the overall center of gravity is stable after stacking, and the height is controlled between 0.9 and 1.7 meters, which facilitates indoor movement and greatly improves the vertical utilization of space.

[0020] Then, the stacked bracket assemblies are sent into the maintenance transfer system. For example... Figure 2As shown, the system logically constructs all maintenance areas as a closed-loop track ("snake"). Newly arrived rack sets, acting as the "snake head," are placed at the very front of the track and labeled with their arrival date. Previously arrived rack sets are arranged sequentially backward ("snake body"). When outbound inspection is required, the "first-in, first-out" principle is strictly followed, and rack sets whose maintenance period has expired are retrieved from the very end of the track ("snake tail"). This logic can be implemented through physical labeling (such as date tags, different colored areas) or combined with simple electronic signage to ensure orderly management and prevent confusion.

[0021] Finally, the tray assemblies were transported to the testing room, where testing personnel directly removed the test blocks from the trays for testing. Thus, from demolding to testing, the test blocks were only handled manually during the initial stacking and final testing. All handling and storage processes were mechanized using the "tray" as the smallest unit, minimizing damage caused by repeated handling.

[0022] Example 1 A construction engineering testing laboratory has limited curing room space, receiving approximately 150 test blocks daily from construction companies. After modification using the system of this invention: Process Implementation: After demolding at the construction site, the construction unit directly stacks the test blocks onto a special bracket (limited to 4 groups per layer, stacked in 5 layers), and transports them to the laboratory by truck. The laboratory uses a manual forklift to unload the entire bracket and stack it on a pallet jack, then pushes it into the curing room. Inside the curing room, the bracket groups are arranged sequentially and tightly along the closed-loop track marked on the wall in a "snake" pattern, without the need for pre-reserved manual passageways.

[0023] Comparison of results: Before the modification, six workers were needed for unloading, handling, and shelving, taking approximately two hours, and the test blocks had a high rate of damage from impacts. After the modification, only one forklift driver and one dispatcher are needed to complete the warehousing and shelving of 150 sets of test blocks within 30 minutes, reducing the test block damage rate by over 90%. Due to the tightly stacked and closed-loop layout of the curing room, the curing capacity of test blocks within the same area has increased by approximately 35%.

[0024] Example 2 Building upon Example 1, to further improve management accuracy, RFID tags can be installed on each tray, and RFID readers can be placed at the entrance and exit of the curing room track. When a tray enters the warehouse, the system automatically records its ID, entry time, and test block information; when the tray reaches the exit and is read, the system automatically prompts whether its curing status has expired. This low-cost information technology upgrade enables the "snake" circulation system to achieve digital monitoring and early warning.

[0025] The system described in this invention achieves near-fully automated maintenance efficiency and quality with relatively low investment through the combination of innovative bracket design, flow logic, and mechanized tools, while maintaining the flexibility and low cost of traditional manual methods. It is particularly suitable for widespread application in a wide range of small and medium-sized testing institutions and construction projects.
