DETAILED DESCRIPTION
[0035] The following is combined with Figure 1-3 This application is described in further detail.
[0036] The present application embodiment discloses a concrete detection device based on a rebound tester, referring to Figure 1 and Figure 2 The concrete testing device based on the rebound tester includes a mounting seat 2, a sliding plate 3, a driving mechanism 1, a locking mechanism 4, a rebound tester 5 and a placement plate 6. The sliding plate 3 is slidably connected to the mounting seat 2, the driving mechanism 1 is installed on the mounting seat 2, the locking mechanism 4 is installed on the sliding plate 3, the central axis of the rebound tester 5 is vertical, the placement plate 6 is arranged on the mounting seat 2, and the bottom end of the rebound tester 5 can abut against the upper surface of the concrete in the placement plate 6.
[0037] The driving mechanism 1 is used to drive the sliding plate 3 to move along the height direction of the mounting seat 2, the locking mechanism 4 is used to fix the rebound test hammer 5, and the placement plate 6 is used to place concrete. During the inspection, the placement plate 6 is placed at the bottom of the mounting seat 2, the concrete is placed in the placement plate 6, the posture of the rebound test hammer 5 is adjusted to ensure that the central axis of the rebound test hammer 5 is vertical, and then fixed by the locking mechanism 4. The locking mechanism 4 is used to fix the rebound test hammer 5, and during the inspection process, the possibility of the rebound test hammer 5 tilting is reduced. The placement plate 6 can reduce the possibility of the concrete block offset during the inspection process. In this way, the problem that the concrete inspection surface and the central axis of the rebound test hammer 5 are easily not perpendicular to each other in the existing inspection method is solved, and the accuracy of the inspection result is improved.
[0038] Specifically, refer to Figure 1 and Figure 2 The mounting base 2 includes a base 21, a horizontal plate 22 and two vertically parallel guide rods 23, and the horizontal plate 22 is connected to the base 21 through the two guide rods 23. The driving mechanism 1 is installed on the horizontal plate 22. In this embodiment, the specific form of the driving mechanism 1 is not limited, and a cylinder, an electric push rod, etc., or a combination of a driving motor and a transmission mechanism can be used. Through the driving mechanism 1, the rebound tester 5 can be automatically driven to move instead of manual labor, and the moving process is more stable and uniform, which can also save labor.
[0039] Reference Figure 1 and Figure 2Since the bottom detection part of the rebound tester 5 needs to abut against the concrete during detection, the driving mechanism 1 needs to drive the rebound tester 5 to move along the length direction of the guide rod 23, that is, drive the sliding plate 3 to move. In order to improve the stability of the sliding plate 3 during the movement process, the sliding plate 3 is inserted into the two guide rods 23 and is slidably connected to the guide rods 23.
[0040] Reference Figure 1 and Figure 2 The locking mechanism 4 includes a mounting frame 41, a first screw 42 and an arc-shaped limit plate 43. The mounting frame 41 is U-shaped and connected to the sliding plate 3. Two first screws 42 and arc-shaped limit plates 43 are provided. The two screws are arranged opposite to each other and are threadedly connected to the mounting frame 41. A through hole for the rebounding hammer 5 to pass through is provided at the bottom of the mounting frame 41. The rebounding hammer 5 is penetrated on the mounting frame 41. The two arc-shaped limit plates 43 are respectively connected to the ends of the two first screws 42 that are close to each other and are connected to the convex side of the arc-shaped limit plates 43. The posture of the rebounding hammer 5 is adjusted to be set vertically. By screwing the two first screws 42 and moving the two first screws 42 in the direction of approaching each other, the rebounding hammer 5 can be clamped to achieve fixation. Of course, in order to improve the fixing effect, an anti-slip pad can be added to the arc-shaped limit plate 43, and a sleeve can be added where the rebounding hammer 5 contacts the mounting frame 41. In this embodiment, when adjusting the posture of the rebound hammer 5, a level gauge or the like may be used to assist in improving accuracy.
[0041] Reference Figure 1 and Figure 2 A clamping mechanism 7 is also installed on the base 21 for clamping and fixing the placement plate 6. The placement plate 6 is fixed by the clamping mechanism 7, which reduces the possibility of movement of the placement plate 6 during the detection process.
[0042] Specifically, the clamping mechanism 7 includes two fixing plates 71 and two second screw rods 72. The two fixing plates 71 are arranged parallel to each other, and there is a gap between the two fixing plates 71 for the placement tray 6 to be placed. The two second screw rods 72 are arranged opposite to each other and are respectively threadedly connected to the fixing plates 71. By screwing the two second screw rods 72 and moving the two second screw rods 72 in a direction close to each other, the placement tray 6 can be clamped to achieve fixation.
[0043] Reference Figure 1 and Figure 2 The clamping mechanism 7 further includes a compression spring 73, and the two ends of the compression spring 73 are respectively connected to the second screw rod 72 and the fixing plate 71. When the second screw rod 72 is screwed to move toward the placement plate 6, the compression spring 73 is squeezed, so that the placement plate 6 has a better clamping effect.
[0044] Reference Figure 1 and Figure 2The base 21 is also provided with a curing bin 8, into which the placement tray 6 can be placed. The concrete is placed in the curing bin 8 for curing, ensuring that the concrete reaches the best temperature and humidity, so that the concrete reaches the best testing conditions, thereby obtaining the most realistic test results. The curing bin 8 can accommodate multiple placement trays 6 at the same time. The curing bin 8 can cure multiple pieces of concrete at the same time, ensuring that the testing conditions of the concrete to be tested are the same, so that the same batch of concrete can be tested multiple times, and the testing conditions can be ensured to be the same, so that the final test data is more accurate.
[0045] Reference Figure 1 and Figure 3 , a baffle plate 9 is installed on the placement tray 6, and a handle 10 is installed on the baffle plate 9. The handle 10 is used to facilitate the staff to move the placement tray 6, thereby improving the convenience of operation. A groove 11 is formed at the bottom of the mounting seat 2 for the baffle plate 9 to partially embed. When the placement tray 6 is placed on the base 21, the baffle plate 9 is inserted into the groove 11, so that the placement tray 6 can be placed horizontally, and the groove 11 can be used to limit the placement tray 6.
[0046] The implementation principle of a concrete testing device based on a rebound tester in the embodiment of the present application is as follows: before testing, each concrete block is placed in the placement tray 6 in sequence, and then the placement tray 6 is placed in the curing bin 8 for curing. After a period of time, the testing is started after the testing conditions are met. During the test, the placement tray 6 is placed in the corresponding position, fixed by the second screw 72, the posture of the rebound tester 5 is adjusted and fixed by the first screw 42, the driving mechanism 1 is started, and the sliding plate 3 is driven to move downward until the bottom of the rebound tester 5 abuts against the surface of the concrete, the rebound tester 5 is started, and the concrete strength is tested, and then a new placement tray 6 is replaced to complete the next test. In this way, the locking mechanism 4 is used to fix the rebound tester 5, and during the test process, the possibility of the posture tilt of the rebound tester 5 is reduced. At the same time, the setting of the clamping mechanism 7 and the placement tray 6 can reduce the possibility of concrete movement. In this way, the problem that the concrete test surface and the central axis of the rebound tester 5 are not perpendicular to each other in the existing testing method is solved, and the accuracy of the test result is improved.
[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
