Abstract
Description
Technical Field
[0001] This utility model relates to the field of testing technology for materials in highway and waterway engineering, specifically to a quick-locking bracket structure for an overflow water tank collection basket and an overflow water tank. Background Technology
[0002] The apparent density and surface-dry density of coarse aggregates are typically determined using the basket method, which is based on Archimedes' displacement method. This method determines the volume of the aggregate by measuring its buoyancy in water. Aggregate density in highway engineering is a crucial indicator of its physical properties, directly impacting the mix design, strength, and stability of concrete and asphalt mixtures. Therefore, the determination of coarse aggregate density has received widespread attention in highway and waterway engineering industries. However, the instruments provided in the existing "Test Procedures for Cement and Cement Concrete in Highway Engineering" (JTG 3432-2024) have the following problems in practical applications:
[0003] 1. Cumbersome and inefficient operation: The entire process requires multiple sample transfers and repeated adjustments to the basket position, and the testing of a single sample takes a long time, making it difficult to meet the high-efficiency requirements of modern engineering testing. Especially during large-scale testing, operators are prone to fatigue, further reducing work efficiency.
[0004] 2. Difficulty in guaranteeing accuracy: When weighing in water, the swaying and unstable position of the basket can introduce significant errors; when wiping surface water, finer coarse aggregates (2.36mm~4.75mm) are easily affected by the adhesion of fine particles, resulting in loss; while larger particles need to be wiped dry one by one, which is greatly influenced by human factors. These operational uncertainties directly affect the accuracy and repeatability of the final density calculation results.
[0005] Therefore, based on the testing methods in the "Test Procedures for Cement and Cement Concrete in Highway Engineering" (JTG 3432-2024), a quick-locking support structure for the overflow tank aggregate basket has been developed to address the deviations in test results caused by the above-mentioned issues. Utility Model Content
[0006] The purpose of this invention is to provide a quick-locking bracket structure for the overflow tank's collection basket and the overflow tank itself. This aims to overcome the shortcomings of existing technologies and address the fact that current testing equipment for overflow tanks cannot quickly position and lock, resulting in unstable weighing during testing and prolonged testing times. To solve these problems and improve the accuracy of test results, this quick-locking bracket structure for the overflow tank's collection basket and the overflow tank were invented. This bracket structure allows for quick positioning and locking, significantly reducing the impact of human intervention.
[0007] Therefore, this utility model proposes a quick-locking support structure for an overflow tank aggregate basket, used to stabilize the basket during coarse aggregate density measurement tests, comprising:
[0008] At least one pair of locking mechanisms are symmetrically arranged on the outside of the basket; the locking mechanisms include:
[0009] A rotary damping connector for fixing to the inner wall of the overflow tank;
[0010] A rod, one end of which is connected to the output end of the rotary damping connector;
[0011] A tube clamp assembly is fixedly connected to the other end of the rod, the tube clamp assembly having an arcuate portion for approaching or receiving the basket;
[0012] The rotary damping connector is configured to provide damping force, enabling the rod to rotate in the horizontal plane and be stably suspended at any angle. By rotating the rod, the tube clamp assembly can be driven to move horizontally to a position close to the net basket, thereby limiting the swaying of the net basket.
[0013] As a preferred technical solution of this application, the rotary damping connector includes a mounting plate for connecting to the overflow tank wall, a connector and a rotating head rotatably connected to the connector via a pin, the pin being arranged in a vertical direction, and the rod being connected to the rotating head.
[0014] As a preferred technical solution of this application, the rod and the rotating head are connected by a thread.
[0015] As a preferred technical solution of this application, the pipe clamp assembly is a pipe clamp assembly, which includes a semi-circular steel strip and a rubber gasket attached to the inner ring side of the steel strip.
[0016] As a preferred technical solution of this application, the outer ring center of the steel strip is fixedly connected to the rod.
[0017] As a preferred embodiment of this application, the rubber gasket is connected to the inner ring side of the steel strip by an adhesive.
[0018] As a preferred embodiment of this application, the two rotary damping connectors in the pair of locking mechanisms are located at the same horizontal level.
[0019] This utility model also proposes an overflow water tank for coarse aggregate density determination test, comprising: a water tank body, a constant temperature control system, and a support structure for quick locking of the aggregate basket. The constant temperature control system is located inside the water tank body and is used to maintain a constant water temperature. The constant temperature control system includes a compressor, a circulating pump, and a circulating pump water pipe connected to the circulating pump. The mounting plate of the rotary damping connector in the support structure for quick locking of the aggregate basket is fixed to the inner side wall of the water tank body.
[0020] As a preferred technical solution of this application, it also includes an electronic balance, a metal hook, a suspension line, and a net basket. The electronic balance is disposed above the water tank body, the metal hook is suspended from the hook of the electronic balance, the suspension line connects the metal hook and the net basket, and the net basket hangs below the liquid surface of the water tank body.
[0021] As a preferred technical solution of this application, an overflow hole is provided on the upper part of the side wall of the water tank body.
[0022] The quick-locking bracket structure for the overflow tank collection basket provided by this utility model has the following beneficial effects:
[0023] 1) Significantly improves efficiency: It can accurately measure the weighing reading of the electronic balance, realize the "one-click" quick positioning and stabilization of the basket, eliminate the process of repeated adjustment and waiting, greatly shorten the detection time of a single sample, save the operation time of the test process, and is especially suitable for large-scale testing operations.
[0024] 2) Significantly improved accuracy: Effectively eliminates weighing errors caused by basket swaying, ensuring the correct mass (M) in the water. W The accuracy and repeatability of the measurements improve the reliability of density calculation results from the source.
[0025] 3) Reduce human influence: Transforming experience-based "feel" operations into standardized, repeatable mechanical positioning reduces the skill requirements for operators, avoids errors caused by human factors, and reduces human error.
[0026] 4) Simple structure and strong compatibility: As an auxiliary device, this device does not require modification of the main structure of the existing overflow tank and balance. It is easy to install and operate, achieves quick locking and high accuracy, and can be widely used in the upgrading and transformation of existing test equipment that conforms to the JTG 3432-2024 standard.

Detailed Implementation
[0032] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0033] like Figures 1-2 As shown, the present invention relates to a quick-locking bracket structure for an overflow water tank collection basket and an overflow water tank. The overflow water tank includes: a water tank body, a constant temperature control system, and a bracket structure. The constant temperature control system is installed inside the water tank body and is used to maintain a constant water temperature. The constant temperature control system includes a circulation pump 11, a circulation pump water pipe 12, and a compressor 13. An overflow hole is provided on the upper part of the side wall of the water tank body.
[0034] The support structure includes at least one pair of locking mechanisms, which include a rotary damping connector 1, a rod 3, and a pipe clamp assembly 2, symmetrically arranged on the outside of the basket 14. The rotary damping connector 1 is configured to provide damping force, allowing the rod 3 to rotate in the horizontal plane and be stably suspended at any angle. By rotating the rod 3, the pipe clamp assembly 2 can be driven to move horizontally to a position close to the basket 14, thereby limiting the swaying of the basket 14.
[0035] The overflow tank also includes an electronic balance 8, a metal hook 9, a suspension line 10, and a net basket 14. The electronic balance 8 is located above the tank body, the metal hook 9 is suspended from the hook of the electronic balance 8, and the suspension line 10 connects the metal hook 9 and the net basket 14, which hangs below the liquid surface of the tank body.
[0036] like Figure 1As shown, before the experiment, the overflow tank is installed and debugged. The compressor 13, circulation pump 11, and circulation pump water pipe 12 are started. The circulation pump 11 is used to pump the water at the bottom of the tank to the top of the tank through the circulation pump water pipe 12, so as to realize the internal circulation of water in the tank and meet the temperature control required for the experiment. The electronic balance 8 is turned on so that its metal hook 9, suspension line 10, and net basket 14 are on a vertical line.
[0037] like Figure 2 As shown, the pipe clamp assembly 2 consists of a steel strip 4 and a rubber gasket 5. The steel strip 4 is a semi-circular ring structure, and its outer ring center is fixedly connected to the rod 3, not limited to welding or threaded connection. The rubber gasket 5 is fixed to the inner ring side of the steel strip 4, and the two are bonded together with double-sided tape or glue to ensure that they do not fall off during the test. A pair of pipe clamp assemblies 2 are symmetrically arranged on the outside of the net basket 14. When the electronic balance is weighing and reading the values, the rubber gasket 5 is used to quickly approach the net basket for approximate locking, thereby saving the test time and ensuring the accuracy of the electronic balance. It is important to note that the rubber gasket 5 should not contact the net basket 14.
[0038] like Figure 2 As shown, the rotary damping connector 1 has a mounting plate 7, a connector 15, a pin 6, and a rotating head 16. The mounting plate 7 and the connector 15 are integrally formed, and the connector 15 and the rotating head 16 are rotatably connected by the pin 6. The mounting plate 7 is fixed to the inner wall of the water tank by welding. The other end of the rotating head 16 is threaded to the rod 3, so that the rod 3 is rotatably connected to the rotary damping connector 1. The pin 6 is set in the vertical direction, so that the entire pipe clamp assembly 2 can only rotate horizontally. In addition, the two rotary damping connectors 1 in the pair of locking mechanisms are located at the same horizontal height.
[0039] During the test, the operator can easily rotate rod 3 horizontally to move a pair of clamp assemblies 2 symmetrically to the vicinity of basket 14. Through the damping characteristics of the rotary damping connector 1, rod 3 can be stably suspended. Fine-tuning the clamp position so that it almost contacts the basket without applying excessive pressure (i.e., the rubber pad 5 does not contact the basket 14 or only makes very slight contact) quickly limits the basket's sway in three-dimensional space, rapidly stabilizing it in the vertical position required for weighing, greatly improving weighing speed and data stability.
[0040] The principle and working process of the quick-locking bracket structure of the overflow water tank collection basket of this utility model are briefly described below.
[0041] Preparation: Start the compressor 13 and circulation pump 11 of the overflow tank to circulate the water in the tank and stabilize the water temperature at 23℃±2℃. Suspend the wire basket 14 on the metal hook 9 of the powered-on electronic balance 8 via the suspension line 10 and immerse it in the water tank.
[0042] Adjustment and Locking: After the basket is submerged, raise and lower it as described in the standard procedure to remove air bubbles. Then, manually rotate the two rods 3 horizontally on both sides to symmetrically adjust the two clamp assemblies 2 to a position close to the basket 14. Thanks to the damping force of the rotary damping connector 1, the rods can be stably suspended, thereby quickly locking the basket into a vertically stable state.
[0043] Weighing the water: Add water to the tank until it overflows from the overflow hole. After the balance reading has completely stabilized, the balance can be zeroed or the stable value can be read directly, which is the mass M of the sample water. W Because the basket has been stabilized, the reading speed is greatly accelerated during this process.
[0044] Subsequent steps: The subsequent steps of saturated surface dry wiping, weighing and drying are carried out in full accordance with the standard method T0304-2024 of the "Test Procedures for Cement and Cement Concrete in Highway Engineering" (JTG 3432-2024).
[0045] Although the quick-locking bracket structure for the overflow tank aggregate basket in this application is a "small" but practical innovation, it precisely solves a series of "pain points" in the coarse aggregate density testing process. It not only improves the accuracy and efficiency of a single test, but more importantly, by promoting the standardization and normalization of the testing process, it provides reliable technical support for ensuring the material quality and structural safety of engineering projects, reflecting the continuous pursuit of precision and efficiency in the field of engineering technology.
[0046] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
