[0002] Water conservancy and hydropower engineering mainly studies the basic knowledge and skills in water resources, hydraulic structures, hydraulics and fluid dynamics, and water conservancy engineering technology, and conducts survey, planning, design, construction, and management of water conservancy and hydropower engineering. Concrete will appear in the construction process of these projects. In order to test the strength of concrete, it is necessary to conduct compressive and tensile tests on concrete.

[0003] For example, a recycled concrete compression test device with announcement number CN222028070U is provided with a first motor, a first threaded column and a first threaded tube. When people need to clean the recycled concrete blocks and debris inside the storage bin, they control the operation of the first motor through a control switch, thereby driving the first threaded column to rotate. With the cooperation of the first threaded column and the first threaded tube, it is convenient to drive the push plate to move, which makes it convenient for people to push the recycled concrete blocks and debris inside the storage bin out of the slag outlet, so as to make it convenient for people to clean the recycled concrete blocks and debris inside the storage bin, thereby improving the practicality of the device. However, in actual use, the detection function of the existing concrete detection equipment is relatively single, and can only perform compression detection or tensile detection. When performing tensile and compression detection on concrete, the concrete test block needs to be placed on different detection equipment, and the concrete test block needs to be removed and fixed.

[0029] 1. The detection components are symmetrically arranged inside the cabinet. During the detection of the concrete test block, the concrete test block is placed in the cabinet, and then the hydraulic cylinder can be controlled to drive the movable plate to move downward so that the movable plate fits the top of the test block. The hydraulic cylinder applies pressure to the movable plate, and the test block can be subjected to a compression test. Later, when the test block is subjected to a tensile test, the movable plate is moved up by the hydraulic cylinder. After the movable plate is moved up, the two sets of movable rods can be driven up by the support frame. After the movable rods are moved up, the connecting frame is moved up. One end of the steel cable is fixed to the connecting frame, and the other end of the steel cable does not move, so that after the movable rod and the connecting frame are moved up, the steel cable is gradually straightened, so that the movable rod slides on the movable block, and the telescopic spring can be stretched, so that The two upper positioning plates clamp the upper parts of both sides of the test block, and the connecting frame can drive the two moving frames to move through the telescopic rod during the movement, so that the moving rod moves, and then the two lower positioning plates can fix the lower parts of both sides of the test block, and then the movable plate continues to move upward, and the test block is fixed by the upper positioning plate and the lower positioning plate. The upper positioning plate is pulled up by the movable plate, and then the test block can be stretched, and the tensile test can be performed on the test block. The test assembly allows the concrete test block to be subjected to compression test and tensile test, avoiding the existence of singleness in the test and avoiding the use of multiple testing equipment during the test, which can save the test time, improve the test efficiency, and facilitate the fixation of the concrete test block, thereby improving the work efficiency and practicality;

[0030] 2. When the test block is subjected to compression test, the hydraulic cylinder extends to move the circular plate downward so that the movable plate contacts the test block, and then the circular plate continues to move downward, and then pressure can be applied to the movable plate through the circular plate, so that the test block can be subjected to compression test, and the pressure of the circular plate can be known through the two first pressure sensors, and the value of the pressure applied during the compression process can be detected. Then, when the test block is subjected to tensile test, the circular plate is moved upward, and after the circular plate moves upward, it abuts against the two second pressure sensors, and then the movable plate can be pulled upward through the fixed frame, and the value of the tension applied during the tensile process can be detected, so that the values ​​of the tension and pressure applied can be accurately known during the tensile and compression tests of the test block, thereby improving the accuracy of the test;

[0031] 3. Before testing the test block, the handle and the push plate are held according to the size of the test block, so that the push plate moves close to the handle, and then the limit rod can be driven to slide on the rotating rod, so that the reset spring can be stretched, and the limit rod can be disengaged from the limit hole, so that the rotating rod loses its limit, and the rotating rod can be rotated to drive the turntable to rotate. After the turntable rotates, the column rod can be pushed to slide in the sliding groove through the sliding connection between the movable groove and the column rod, and then the adjusting rod can be driven to slide on the U-shaped frame, so that the three positioning bars move synchronously, and the placement of the test block can be positioned through the two positioning bars. After that, the handle and the push plate can be loosened, and the limit rod can be engaged with the other limit hole under the action of the reset spring to limit the turntable. After that, the test block is clamped by the manipulator and placed in the cabinet, so that the test block is respectively fitted with the three positioning bars, thereby ensuring that the test block is in the center of the workbench, and avoiding the test block placement offset in the subsequent testing process to affect the detection accuracy, thereby improving practicality.

[0060] Working principle: When using the concrete quality detection device for water conservancy and hydropower projects, first, according to Figure 1-Figure 9 As shown, the detection assembly 2 is symmetrically arranged inside the cabinet 102. During the detection of the concrete test block, the concrete test block is placed in the cabinet 102, and then the hydraulic cylinder 104 can be controlled to drive the movable plate 106 to move downward, so that the movable plate 106 fits with the top of the test block. The hydraulic cylinder 104 applies pressure to the movable plate 106, so that the test block can be subjected to a compression test. Thereafter, when the test block is subjected to a tensile test, the movable plate 106 is moved upward by the hydraulic cylinder 104. After the movable plate 106 is moved upward, the two sets of movable rods 204 can be driven upward by the support frame 207. After the movable rods 204 are moved upward, the connecting frame 208 is moved upward, and one end of the steel cable 210 is fixed to the connecting frame 208, and the other end of the steel cable 210 does not move, thereby After the movable rod 204 and the connecting frame 208 move upward, the steel cable 210 is gradually straightened, so that the movable rod 204 slides on the movable block 203, and the telescopic spring 205 can be stretched, so that the two upper positioning plates 209 can clamp the upper sides of the test block, and the connecting frame 208 can drive the two movable frames 213 to move through the telescopic rod 215 during the movement, so that the movable rod 212 moves, and then the two lower positioning plates 214 can fix the lower sides of the test block, and then the movable plate 106 continues to move upward, and the test block is fixed by the upper positioning plate 209 and the lower positioning plate 214. The movable plate 106 moves upward to pull the upper positioning plate 209 upward, so that the test block can be stretched, and the tensile test can be performed on the test block;

[0061] When the test block is subjected to a compression test, the hydraulic cylinder 104 extends to move the circular plate 108 downward, so that the movable plate 106 contacts the test block, and then the circular plate 108 continues to move downward, and then the circular plate 108 can apply pressure to the movable plate 106, so that the test block can be subjected to a compression test, and the pressure of the circular plate 108 can be known through the two first pressure sensors 109, and the value of the pressure applied during the compression test can be detected. Then, when the test block is subjected to a tensile test, the circular plate 108 is moved upward, and after the circular plate 108 moves upward, it abuts against the two second pressure sensors 110, and then the movable plate 106 can be pulled upward by the fixing frame 107, and the value of the tension applied during the tensile test can be detected, so that the values ​​of the tension and pressure applied can be accurately known during the tensile and compressive tests of the test block, thereby improving the accuracy of the test. Before the test block is tested, the handle 309 and the push plate 313 are held according to the size of the test block, so that the push plate 313 moves close to the handle 309, and then the limit rod 31 can be driven. 0 slides on the rotating rod 308, so that the reset spring 311 can be stretched, and the limiting rod 310 is separated from the limiting hole 312, so that the rotating rod 308 loses its limit, and the rotating rod 308 can be rotated to drive the rotating disk 306 to rotate. After the rotating disk 306 rotates, the sliding connection between the movable groove 307 and the column rod 304 can push the column rod 304 to slide in the sliding groove 305, and then the adjusting rod 302 can be driven to slide on the U-shaped frame 301, so that the three positioning bars 303 move synchronously. The positioning bar 303 can be used to position the test block, and then the handle 309 and the push plate 313 can be loosened, and the limit rod 310 is engaged with another limit hole 312 under the action of the reset spring 311 to limit the turntable 306. Then the test block is clamped by a robot and placed in the cabinet 102, so that the test block is respectively fitted with the three positioning bars 303, thereby ensuring that the test block is in the center of the workbench 1, and avoiding the test block placement offset to affect the detection accuracy in the subsequent detection process, thereby improving practicality.
