Description

Technical Field

[0001] This utility model relates to the field of concrete precast equipment technology, and in particular to a concrete test block production and testing system. Background Technology

[0002] With the development of the infrastructure industry, the requirements for concrete quality testing are constantly increasing. Concrete quality is one of the important factors affecting project quality, and the performance of concrete test blocks is an important parameter for evaluating concrete quality. As the demand for concrete continues to increase, concrete test blocks also need to be industrialized to meet large-scale demand. Traditional concrete test block production relies heavily on manual operation, which is inefficient, especially when large quantities of concrete need to be tested. This requires a large workforce, and manual operation makes it difficult to maintain consistent processes such as vibration time, curing conditions, and test block demolding and transportation, leading to fluctuations in test block quality and affecting the reliability of test results.

[0003] To address this, several mechanized and automated prefabrication and testing solutions for test blocks have emerged on the market. For example, the fully automated intelligent curing and strength testing system for concrete test blocks disclosed in CN114858555A provides a complete production line system for concrete test blocks from standard curing upon entry into the warehouse, exit from the warehouse, demolding, robotic transfer, and pressure testing. It automates the process from standard curing upon entry into the warehouse to pressure testing, but lacks test block production and test block pallet return. Another example is an integrated concrete test block system based on a truss robotic arm disclosed in CN117325298A. This system provides an automated production solution for concrete test blocks from test block filling vibration, static curing upon entry into the warehouse, demolding, empty mold cleaning, and release agent spraying. However, it lacks the entire production process for test blocks and cannot achieve the return of empty molds after demolding. Utility Model Content

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Example 1

[0030] Figure 1 This illustration shows an embodiment of the concrete test block production and testing system of this utility model. The concrete test block production and testing system of this embodiment includes a filling line 1, a curing chamber component 2, a mold return line 3, a test block conveying line 4, a testing conveying line 5, a testing machine 6, and a test block tray return line 7. The first end of the filling line 1 is connected to the curing chamber component 2. The first end of the mold return line 3 is connected to the curing chamber component 2, and the second end is connected to the second end of the filling line 1. The mold return line 3 is provided with a demolding device 31. The first end of the test block conveying line 4 is connected to the demolding device 31, and the second end is connected to the curing chamber component 2. The first end of the testing conveying line 5 is connected to the curing chamber component 2, and the second end is connected to the testing machine 6. The first end of the test block tray return line 7 is connected to the testing conveying line 5, and the second end is connected to the second end of the test block conveying line 4.

[0031] In this embodiment of the concrete test block production and testing system, the filling line 1 fills the concrete into the test block mold, and then the test block mold is transferred to the curing chamber assembly 2 for static curing. After static curing for 1-2 days, it is transferred out of the curing chamber assembly 2 to the mold return line 3, where it is demolded at the demolding device 31. The test block mold continues to return to the filling line 1 for reuse, while the test blocks are transferred to the test block conveyor line 4, and then from the test block conveyor line 4 to the test block tray of the curing chamber assembly 2, where standard curing (generally at a certain temperature) is completed. After curing in an environment of 20℃±2℃ and relative humidity above 95% (usually for 28 days), the test blocks are transferred to test conveyor line 5 and then transported to test machine 6 for pressure testing. After all the test blocks on the test block tray are removed, the test block tray returns along test conveyor line 5 and is then transferred to test block tray return line 7. When it reaches the second end of test block tray return line 7, it waits for the subsequent test blocks to be transported by test block conveyor line 4. The structure is simple, the degree of automation is high, and the continuous recycling of molds and test block trays can be realized.

[0032] Furthermore, in this embodiment, the curing chamber component 2 includes a curing chamber body 21. The curing chamber body 21 has a first curing chamber inlet / outlet track 211 and a second curing chamber inlet / outlet track 212 on opposite sides. Preferably, a transfer trolley can be set on the first curing chamber inlet / outlet track 211 and the second curing chamber inlet / outlet track 212 to realize the entry and exit of test blocks into and out of the curing chamber body 21. The first end of the filler line 1 is connected to the first end of the first curing chamber inlet / outlet track 211, the first end of the test conveyor line 5 is connected to the second end of the first curing chamber inlet / outlet track 211, the first end of the mold return line 3 is connected to the first end of the second curing chamber inlet / outlet track 212, and the second end of the test block conveyor line 4 is connected to the second end of the second curing chamber inlet / outlet track 212. After the test block mold is filled, it is transferred to the inlet / outlet track 211 of the first curing chamber, and then transferred into the main body 21 of the curing chamber for static curing. After static curing, it is transferred out to the inlet / outlet track 212 of the second curing chamber, and then transferred out to the mold return line 3. The test block is transferred through the test block conveyor line 4 to the inlet / outlet track 212 of the second curing chamber, and then transferred into the main body 21 of the curing chamber for standard curing. After standard curing, it is transferred out to the inlet / outlet track 211 of the first curing chamber, and then transferred out to the test conveyor line 5. That is, in this embodiment, static curing and standard curing are both carried out in the main body 21 of the curing chamber. Accordingly, the inlet / outlet track 211 of the first curing chamber and the inlet / outlet track 212 of the second curing chamber are used for both transferring test blocks into and out of the main body 21 of the curing chamber. The overall structure is compact and occupies little factory space.

[0033] In a preferred embodiment, the curing chamber body 21 is located within the area enclosed by the first curing chamber inlet / outlet track 211, the second curing chamber inlet / outlet track 212, the mold return line 3, and the test block tray return line 7. The first curing chamber inlet / outlet track 211, the second curing chamber inlet / outlet track 212, the mold return line 3, and the test block tray return line 7 surround the curing chamber body 21, which helps to shorten the transfer distance and thus improve the system's production efficiency.

[0034] Furthermore, in this embodiment, the filling line 1 is equipped with a placing boom 11 and a placing vibration table 12, and the placing boom 11 is equipped with a material take-up machine 13. The material take-up machine 13 generally takes the concrete to be tested from the discharge port of the concrete mixing plant or the concrete transport truck and transfers it into the placing boom 11. The placing boom 11 completes the filling of the test block mold, and the placing vibration table 12 is used to vibrate and compact the concrete in the test block mold.

[0035] Furthermore, in this embodiment, the mold return line 3 is also provided with a first flipping device 32 and a second flipping device 33, and the demolding device 31 is located between the first flipping device 32 and the second flipping device 33. Before demolding, the test block mold is first flipped using the first flipping device 32 so that the opening of the test block mold is arranged downwards, which greatly reduces the difficulty of demolding by the demolding device 31. After demolding is completed, the test block mold is flipped again using the second flipping device 33 so that the opening of the test block mold is arranged upwards again, so that it can be reused. The structure is reasonable and effective.

[0036] Furthermore, in this embodiment, the second flipping device 33 is located downstream of the demolding device 31, and a demolding liquid spraying device 34 is provided downstream of the second flipping device 33. After the demolding liquid spraying device 34 sprays the demolding liquid onto the test block mold, it facilitates the separation of the test block from the mold during demolding.

[0037] Furthermore, in this embodiment, a first transfer robot 91 is provided between the second end of the test block conveyor line 4 and the curing chamber assembly 2, and a second transfer robot 92 is provided between the second end of the test conveyor line 5 and the testing machine 6. The first transfer robot 91 facilitates the grabbing and transfer of test blocks conveyed from the test block conveyor line 4 to the test block tray; the second transfer robot 92 facilitates the grabbing and transfer of test blocks on the test block tray to the testing machine 6 for pressure testing.

[0038] Example 2

[0039] Figure 2 This invention illustrates another embodiment of the concrete specimen production and testing system. The concrete specimen production and testing system in this embodiment is essentially the same as that in Embodiment 1, except that:

[0040] In this embodiment, the curing chamber assembly 2 includes a static curing chamber 22 and a standard curing chamber 23. The static curing chamber 22 has a static curing chamber inlet track 221 and a static curing chamber outlet track 222 on opposite sides. The first end of the filler line 1 is connected to the static curing chamber inlet track 221, and the first end of the mold return line 3 is connected to the static curing chamber outlet track 222. The standard curing chamber 23 has a standard curing chamber inlet track 231 and a standard curing chamber outlet track 232 on opposite sides. The second end of the test block conveyor line 4 is connected to the standard curing chamber inlet track 231, and the first end of the test conveyor line 5 is connected to the standard curing chamber outlet track 232. Preferably, the static curing chamber inlet track 221, the static curing chamber outlet track 222, the standard curing chamber inlet track 231, and the standard curing chamber outlet track 232 are respectively equipped with transfer trolleys to realize the entry and exit of test blocks into and out of the static curing chamber 22 and the standard curing chamber 23.

[0041] In this embodiment of the concrete specimen production and testing system, static curing and standard curing are carried out in static curing room 22 and standard curing room 23, respectively. The functional zoning of the system is clearer, which helps to avoid confusion between the static curing and standard curing processes. The disadvantage is that it increases the factory area occupied by the system.

[0042] Furthermore, in this embodiment, the second end of the test block conveyor line 4 is equipped with a deburring device 41 and a coding device 42. The first transfer robot 91 picks up the test blocks conveyed by the test block conveyor line 4 one by one, removes burrs and codes information using the deburring device 41 and the coding device 42, and then places them on the test block tray and transfers them to the standard curing room 23 for standard curing. This can further improve the quality of the test blocks and at the same time make it easier for operators to intuitively understand the production information of the test blocks.

[0043] Example 3

[0044] Figures 3-4 This invention illustrates another embodiment of the concrete specimen production and testing system. The concrete specimen production and testing system in this embodiment is basically the same as that in Embodiment 2, except that:

[0045] In this embodiment, the filling line 1, the curing chamber 22, the mold return line 3 and the test block conveying line 4 are located on the upper layer, and the standard curing chamber 23, the test conveying line 5, the test machine 6 and the test block tray return line 7 are located on the lower layer. The second end of the test block conveying line 4 is connected to the standard curing chamber feeding track 231 through a lifting and transfer device 8.

[0046] Considering that mixing plants are generally multi-story buildings with small single-story spaces, the filling line 1, curing chamber 22, mold return line 3 and test block conveying line 4 are arranged on the upper floor, while the standard curing chamber 23, test conveying line 5, test machine 6 and test block tray return line 7 are arranged on the lower floor. The transfer between the upper and lower floors is carried out through the lifting device 8, which facilitates the flexible layout of the system in the mixing plant and has a wider range of applications.

[0047] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the protection scope of the present invention.
