Description

Technical Field

[0001] The invention relates to the technical field of concrete quality detectors, and in particular to a concrete quality detector and a detection method for building construction. Background Art

[0002] Concrete quality testers are devices used to evaluate the strength, density and other key properties of concrete during construction. Common types include rebound testers, ultrasonic testers, rebar detectors and pressure testers. These instruments help ensure the safety and durability of concrete structures.

[0003] For example, the "A concrete quality tester for construction" with publication number: CN221100341U includes a platform, a working groove is arranged on the upper surface of the platform, an anti-splash mechanism is arranged on the upper surface of the platform, a resistance detection mechanism is arranged on the upper surface of the platform, and a clamping mechanism is arranged inside the working groove. By arranging the platform, the working groove, the anti-splash mechanism, the resistance detection mechanism and the clamping mechanism, when in use, the working groove is first arranged on the upper surface of the platform, and then the concrete slab can be detected by the resistance detection mechanism. The debris generated during the detection process can be blocked by the anti-splash mechanism and remain in the working groove. After the detection is completed, the generated slag remains in the working groove. At this time, the staff can make the slag enter the receiving frame through the leakage chute to collect the slag.

[0004] Although this type of concrete quality tester can block debris through the baffle during the testing process to prevent debris from splashing, it is lacking in the adjustment of the baffle. Since this baffle mechanism requires the staff to manually close the baffle after placing the concrete sample, in the process of testing multiple groups of concrete, not only does it take a lot of time and energy to constantly open and close the baffle, but it can also result in the staff forgetting to close the baffle due to negligence. When the baffle is open, the staff may be injured by the splash of the concrete sample. Summary of the invention

[0015] A detection method for a concrete quality detector for building construction, comprising the following steps:

[0016] S1. When testing the concrete sample, just place the concrete sample on the test plate, and then drive the top plate downward through the cylinder. The top plate will drive the pressure plate downward through the transmission column. When the concrete sample is under pressure, the pressure will be transmitted to the gravity monitor through the test plate, thereby completing the compression test of the concrete sample;

[0017] S2. When the top plate moves downward, the top plate will drive the connecting plate to slide downward inside the gantry through the connecting rod, and the connecting plate will drive the rack A to move downward inside the test bench, thereby driving the gear C to rotate, and the gear C will drive the connecting shaft to rotate, and the connecting shaft will drive the bevel gear A to rotate, and the bevel gear A will drive the bevel gear B to rotate, thereby driving the screw rod to rotate, and when the screw rod rotates, it will drive the transmission plate to move upward inside the test bench, thereby driving the baffles A on both sides of the transmission plate to move upward, and as the top plate drives the pressure plate to continue to descend, the baffles A at both ends of the transmission plate will continue to rise, so that the concrete blocks splashed from the concrete sample are collected through the guide trough A in the baffle A, and the guide trough A will guide the concrete blocks to the guide trough B, and then the guide trough B will discharge the concrete blocks from the test bench;

[0018] S3. When it is necessary to transport the concrete sample, it is only necessary to turn on the bidirectional motor, the bidirectional motor will drive the gear D to rotate, the gear D will drive the rack B to slide between the limit slots C, and the rack B will drive the roller to roll in the limit slots C, and the rack B will also drive the push plate to move on the top surface of the testing table. At this time, the concrete sample will move through the roller A inside the testing table, so as to transport the concrete sample. When the concrete sample moves to the testing plate, it can be tested by the gravity monitor. When the concrete sample needs to be taken out after the test, it only needs to be transported by the push plate until the concrete sample is pushed to the guide rack; as the rack B continues to move, the rack B will also drive the warning rod to slide out of the limit slot B. After the warning rod slides out of the limit slot B, the warning rod will be subjected to the torsion of the torsion spring, so that the warning rod rotates downward, and the warning rod can be deployed after it touches the limit block, thereby preventing the staff from being hit by the concrete sample after approaching the guide rack;

[0019] S4. Before the concrete sample is transported to the ground through the guide rack, the concrete sample will be blocked by the guide plate. After the guide plate is subjected to gravity, the guide plate will rotate in the connecting block through the rotating rod B. When the guide plate B drives the soft pad to fit the ground, the concrete sample can be taken out through the roller B in the guide plate. After the concrete sample is taken out from the guide plate, the guide plate will rotate due to the torsion of the torsion spring B, thereby resetting the guide plate. The design of the guide plate has the effect of buffering and unloading the concrete sample when it falls, thereby preventing the concrete sample from damaging the ground or falling to the ground and splashing.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. In the present invention, the connecting plate is driven to move downward by the connecting rod, thereby driving the rack A to move downward, at which time the gear C drives the connecting shaft to rotate, and the connecting shaft drives the bevel gear B to rotate through the bevel gear A, thereby driving the screw to rotate, and when the screw rotates, it drives the transmission plate to slide upward inside the detection table, thereby driving the baffle A to move upward, so that the splashed concrete blocks are collected through the guide trough A in the baffle A, and the guide trough A guides the concrete blocks to the guide trough B, and then the guide trough B discharges the concrete blocks from the detection table, thereby avoiding the need for the staff to manually open and close the baffle continuously, saving manpower and also preventing the staff from being injured due to the baffle A not being closed.

[0022] 2. In the present invention, the gear D is driven to rotate by the motor, and the gear D will drive the rack B to slide between the limit grooves C, and the rack B will drive the roller to roll in the limit groove C. At the same time, the rack B will also drive the push plate to move on the top surface of the test bench, thereby conveying the concrete sample until the concrete sample is pushed to the guide rack. As the rack B continues to move, the rack B will also drive the warning rod to slide out of the limit groove B. After the warning rod slides out of the limit groove B, the warning rod will be subjected to the torsion force of the torsion spring, thereby causing the warning rod to rotate downward. After the warning rod touches the limit block, the warning rod can be deployed, thereby preventing the staff from being hit by the concrete sample after approaching the guide rack.

[0023] 3. In the present invention, the concrete sample is blocked by the guide plate. When the guide plate is subjected to gravity, the guide plate will rotate in the connecting block through the rotating rod B. When the guide plate B drives the soft pad to fit the ground, the concrete sample can be taken out through the roller B in the guide plate. After the concrete sample is taken out from the guide plate, the guide plate will rotate due to the torsion of the torsion spring B, thereby resetting the guide plate. The design of the guide plate has the effect of buffering and unloading the concrete sample when it falls, thereby preventing the concrete sample from damaging the ground or falling to the ground and splashing.

[0041] As the rack B205 continues to move, the rack B205 will also drive the warning rod 207 to slide out of the limit groove B200. After the warning rod 207 slides out of the limit groove B200, the warning rod 207 will be subjected to the torsion force of the torsion spring, thereby causing the warning rod 207 to rotate downward. After the warning rod 207 touches the limit block 210, the warning rod 207 can be deployed, thereby preventing the staff from being injured by the concrete sample after approaching the guide rack 2.

[0042] Embodiment 3: According to Figure 2 and Figure 7 As shown, a connecting block 300 is fixedly installed at the bottom end of the material guide frame 2, and rotating rods B302 are rotatably connected to both sides of the interior of the connecting block 300, and a torsion spring B303 is sleeved on the surface of the rotating rod B302. A material guide plate 301 is fixedly installed at one end of the rotating rod B302, and a rotating rod C305 is rotatably connected to the interior of the material guide plate 301, and a roller B304 is fixedly installed on the surface of the rotating rod C305.

[0043] In this embodiment, the concrete sample is blocked by the guide plate 301. After the guide plate 301 is subjected to gravity, the guide plate 301 will rotate in the connecting block 300 through the rotating rod B302. When the guide plate 301B drives the soft pad 306 to fit the ground, the concrete sample can be taken out through the roller B304 in the guide plate 301. After the concrete sample is taken out from the guide plate 301, the guide plate 301 will rotate due to the torsion of the torsion spring B303, so that the guide plate 301 is reset. The design of the guide plate 301 has the effect of buffering and unloading the concrete sample when it falls, thereby preventing the concrete sample from damaging the ground or falling to the ground and splashing.

[0044] In the present invention, when testing the concrete sample, it is only necessary to place the concrete sample on the testing plate 22, and then open the cylinder 4, the cylinder 4 will drive the top plate 5 to move downward, and the top plate 5 will drive the pressure plate 7 to move downward through the transmission column 6, and after the concrete sample is subjected to pressure, the pressure will be transmitted to the gravity monitor 21 through the testing plate 22, thereby completing the compression test of the concrete sample;

[0045] When the baffle A17 needs to be raised, the top plate 5 only needs to be moved downward, thereby driving the connecting plate 9 to slide downward inside the gantry 3 through the connecting rod 8, and the connecting plate 9 will drive the rack A10 to move downward inside the detection platform 1, thereby driving the gear C11 to rotate, and the gear C11 will drive the connecting shaft 12 to rotate when rotating, and the connecting shaft 12 will drive the bevel gear A13 to rotate, and the bevel gear A13 will drive the bevel gear B14 to rotate, thereby driving the screw rod 15 to rotate, and the screw rod 15 will rotate. When rotating, the transmission plate 16 will be driven to move upward inside the testing platform 1, thereby driving the baffles A17 on both sides of the transmission plate 16 to move upward. As the top plate 5 drives the pressure plate 7 to continuously descend, the baffles A17 on both ends of the transmission plate 16 will also continuously rise, so that the concrete blocks splashed from the concrete sample will be collected through the guide trough A18 in the baffle A17, and the guide trough A18 will guide the concrete blocks to the guide trough B19, and then the guide trough B19 will discharge the concrete blocks from the testing platform 1;

When the concrete sample needs to be taken out after the test is completed, it only needs to be pushed again by the push plate 204 until the concrete sample is pushed to the guide rack 2;

[0047] As the rack B205 continues to move, the rack B205 will also drive the warning rod 207 to slide out of the limit groove B200. After the warning rod 207 slides out of the limit groove B200, the warning rod 207 will be subjected to the torsion force of the torsion spring, so that the warning rod 207 rotates downward. After the warning rod 207 touches the limit block 210, the warning rod 207 can be deployed, thereby preventing the staff from being injured by the concrete sample after approaching the guide rack 2.

[0048] Before the concrete sample is transported to the ground through the guide rack 2, the concrete sample will be blocked by the guide plate 301. After the guide plate 301 is subjected to gravity, the guide plate 301 will rotate in the connecting block 300 through the rotating rod B302. When the guide plate 301B drives the soft pad 306 to fit the ground, the concrete sample can be taken out through the roller B304 in the guide plate 301. After the concrete sample is taken out from the guide plate 301, the guide plate 301 will rotate due to the torsion of the torsion spring B303, thereby resetting the guide plate 301.

2. The concrete quality detector for construction according to claim 1, characterized in that: The connecting rod (8) is slidably connected to the gantry (3), the connecting plate (9) and the rack A (10) are slidably connected to the gantry (3) and the testing platform (1), the rack A (10) is meshed with the gear C (11), and the bevel gear A (13) is meshed with the bevel gear B (14).

3. A detection method for a concrete quality detector for building construction, characterized in that: The concrete quality detector for construction according to claim 2 is used, comprising the following steps: S1. When testing a concrete sample, the concrete sample only needs to be placed on the testing plate (22), and then the top plate (5) is driven downward by the cylinder (4). The top plate (5) drives the pressing plate (7) downward through the transmission column (6). When the concrete sample is subjected to pressure, the pressure is transmitted to the gravity monitor (21) through the testing plate (22), thereby completing the compression test of the concrete sample. S2. When the top plate (5) moves downward, the top plate (5) drives the connecting plate (9) to slide downward inside the gantry (3) through the connecting rod (8), and the connecting plate (9) drives the rack A (10) to move downward inside the detection platform (1), thereby driving the gear C (11) to rotate, and the gear C (11) drives the connecting shaft (12) to rotate, and the connecting shaft (12) drives the bevel gear A (13) to rotate, and the bevel gear A (13) drives the bevel gear B (14) to rotate, thereby driving the screw rod (15) to rotate, and the screw rod (15) will rotate when rotating. The transmission plate (16) is driven to move upward inside the testing platform (1), thereby driving the baffles A (17) on both sides of the transmission plate (16) to move upward. As the top plate (5) drives the pressure plate (7) to continuously descend, the baffles A (17) at both ends of the transmission plate (16) will also continuously rise, thereby collecting the concrete blocks splashed from the concrete sample through the guide trough A (18) in the baffle A (17), and the guide trough A (18) will guide the concrete blocks to the guide trough B (19), and then the guide trough B (19) will discharge the concrete blocks from the testing platform (1); S3. When it is necessary to transport the concrete sample, the bidirectional motor (202) only needs to be turned on. The bidirectional motor (202) will drive the gear D (203) to rotate, and the gear D (203) will drive the rack B (205) to slide between the limit grooves C (201), and the rack B (205) will drive the roller (206) to roll in the limit grooves C (201). At the same time, the rack B (205) will also drive the push plate (204) to move on the top surface of the testing platform (1). At this time, the concrete sample will move through the roller A (211) inside the testing platform (1), so as to transport the concrete sample. When the concrete sample moves to the testing plate (22), the gravity monitor (21) can be used to monitor the concrete sample. The detection is carried out. When the concrete sample needs to be taken out after the detection is completed, it only needs to be transported by the push plate (204) until the concrete sample is pushed to the guide rack (2); as the rack B (205) continues to move, the rack B (205) will also drive the warning rod (207) to slide out of the limit groove B (200). After the warning rod (207) slides out of the limit groove B (200), the warning rod (207) will be subjected to the torsion force of the torsion spring, so that the warning rod (207) rotates downward. After the warning rod (207) touches the limit block (210), the warning rod (207) can be unfolded, thereby preventing the staff from being hit by the concrete sample after approaching the guide rack (2); S4. Before the concrete sample is transported to the ground through the guide rack (2), the concrete sample will be blocked by the guide plate (301). After the guide plate (301) is subjected to gravity, the guide plate (301) will rotate in the connecting block (300) through the rotating rod B (302). When the guide plate (301) B drives the soft pad (306) to fit the ground, the concrete sample can be taken out through the roller B (304) in the guide plate (301). After the concrete sample is taken out from the guide plate (301), the guide plate (301) will rotate due to the torsion of the torsion spring B (303), thereby resetting the guide plate (301). The design of the guide plate (301) has the effect of buffering and unloading the concrete sample when it falls, thereby preventing the concrete sample from damaging the ground or falling on the ground and splashing.
