[0002] Aggregate, also known as aggregate, is divided into coarse aggregate and fine aggregate and is one of the main components of concrete. It primarily serves as a framework and reduces volume changes caused by shrinkage and expansion of the cementitious material during the setting and hardening process. It also serves as an inexpensive filler for the cementitious material. Robustness refers to the ability of aggregate to withstand repeated immersion and drying in a saturated sodium sulfate solution without significant damage or loss of strength. It is an important indicator of aggregate frost resistance. Aggregate robustness testing is performed using an aggregate robustness tester. Currently, aggregate robustness testing using an aggregate robustness tester is of great significance for the use of aggregates in water conservancy projects.

[0003] A Chinese utility model (publication number: CN219695124U) discloses an aggregate strength test device, which includes a square frame-shaped aggregate strength tester, and a cylindrical detection barrel fixedly connected to the upper surface of the aggregate strength tester, so that the detection frame on the upper surface of the aggregate strength tester, which is located on the side of the detection barrel, can drive the aggregate to rise and fall, and perform a strength test inside the detection barrel.

[0004] During the development of the present invention, the inventors discovered that this technology presents at least the following problems: During aggregate solidity testing, it is typically necessary to heat the solution within the test barrel to maintain it within a relatively constant temperature range.

DETAILED DESCRIPTION

[0030] The following is combined with Figures 1-3 This application is described in further detail.

[0031] Please refer to Figures 1-2 A water conservancy project aggregate solidity test device includes an aggregate solidity tester body 1, a detection barrel 2 installed above the aggregate solidity tester body 1, and a lifting detection frame 3 installed on the aggregate solidity tester body 1 and located on the side of the detection barrel 2. The lifting detection frame 3 is a prior art in aggregate solidity testers. The detection barrel 2 is designed with a double-layer stainless steel structure, and a vacuum chamber 14 is formed between the inner and outer layers of the stainless steel structure. The setting of this structure is conducive to improving the heat preservation effect of the detection barrel 2 and reducing the internal heat loss. A discharge pipe 17 is installed at the bottom of the detection barrel 2, and a control valve 18 is installed on the discharge pipe 17. The discharge pipe 17 is used to discharge the solution inside the detection barrel 2, and the control valve 18 controls the opening and closing of the discharge pipe 17. An inclined plate 19 is installed on the inner bottom wall of the detection barrel 2. The inclined plate 19 is inclined toward the discharge pipe 17. The setting of the inclined plate 19 is conducive to the solution at the bottom of the detection barrel 2 to flow to the discharge pipe 17 and be discharged.

[0032] Reference Figures 1-3 A horizontal plate 4 is fixedly mounted on the top of the test barrel 2. A suspension mechanism for suspending an aggregate basket is mounted on the horizontal plate 4. A freely bendable connecting rope 20 is fixedly mounted between the top of the suspension mechanism and the lifting end of the lifting test frame 3. The lower portion of the suspension mechanism is located within the test barrel 2. A lid 5 is mounted on the top of the test barrel 2. The lid 5 can be made of an insulating material or employ a double-layer design similar to the test barrel 2 to improve isolation from the external ambient temperature. The lid 5 has a notch 6 that matches the horizontal plate 4. By suspending the aggregate basket below the suspension mechanism and placing the lid 5 on the top of the test barrel 2, when the lifting test frame 3 drives the suspension mechanism and the aggregate basket to rise and fall for the aggregate strength test, the interior of the test barrel 2 is isolated from the outside, preventing the temperature of the solution inside the test barrel 2 from being lost. This facilitates the smooth conduct of aggregate strength tests for water conservancy projects. An annular plate 16 is fixedly mounted on the lower surface of the barrel cover 5 , and the annular plate 16 is plugged into the interior of the detection barrel 2 , and the connection between the barrel cover 5 and the detection barrel 2 is achieved by plugging, which is convenient for disassembly and assembly of the barrel cover 5 .

[0033] ReferenceFigure 1 and Figure 2 The hanging mechanism includes a vertical rod 7, a mounting sleeve 8, a horizontal rod 9, a steel chain 10 and a hook 11. The vertical rod 7 slides through one end of the horizontal plate 4. The top of the vertical rod 7 is fixedly connected to the connecting rope 20. The surface of the vertical rod 7 is located below the horizontal plate 4 and is equipped with a mounting sleeve 8. Several horizontal rods 9 arranged in a circular array are fixedly installed on the surrounding side of the mounting sleeve 8. A steel chain 10 is fixedly installed at one end of the horizontal rod 9, and a hook 11 is installed at the bottom of the steel chain 10. By hanging the net basket containing the aggregate on the hook 11, the lifting end of the lifting detection frame 3 drives the vertical rod 7 to rise and fall through the connecting rope 20, thereby driving the net basket on the hook 11 to move up and down, so as to carry out the solidity test of the aggregate. The mounting sleeve 8 is slidably mounted on the surface of the vertical rod 7. A number of equally spaced screw holes 12 are provided on the surface of the vertical rod 7. A bolt 13 is threadedly connected to the mounting sleeve 8. One end of the bolt 13 is threadedly connected to the inside of the screw hole 12. By moving the position of the mounting sleeve 8 on the vertical rod 7 and fixing it with the bolt 13, the height of the hook 11 inside the detection barrel 2 can be adjusted to adapt to aggregate baskets of different heights.

[0034] Reference Figure 2 A filter plate 15 is installed at the bottom of the detection barrel 2. When the lifting detection frame 3 drives the aggregate basket on the suspension mechanism to perform the aggregate firmness test, when large particles of aggregate fall, they can be blocked and collected by the filter plate 15.

[0035] The implementation principle of the present utility model is as follows: by hanging the net basket containing the aggregate on the hook 11 and covering the top of the detection barrel 2 with the bucket cover 5, the lifting end of the lifting detection frame 3 drives the vertical rod 7 to move up and down through the connecting rope 20, thereby driving the net basket on the hook 11 to move up and down, so as to carry out the solidity test of the aggregate. During this period, the bucket cover 5 isolates the inside of the detection barrel 2 from the external environment, and it is not easy to cause the temperature of the solution inside the detection barrel 2 to be lost, which is conducive to the smooth progress of the aggregate solidity test for water conservancy projects; moreover, the detection barrel 2 is designed as a double-layer stainless steel structure, and a vacuum chamber 14 is formed between the inner and outer layers of the stainless steel structure, which is conducive to improving the thermal insulation effect of the detection barrel 2 and reducing the loss of internal heat.

[0036] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
