Description

Technical Field

[0001] The utility model relates to the technical field of concrete strength detection equipment, in particular to a concrete strength detector. Background Art

[0002] When pouring concrete in engineering construction, in order to ensure the quality of the main body of the construction project, it is usually necessary to first adjust the proportion of concrete materials. After the concrete dries, its strength needs to be detected. Therefore, in order to prepare some concrete test blocks for detection to ensure the project quality, at present, most concrete strength detections are carried out using a rebound hammer, which is a commonly used tool for concrete strength detection:

[0003] However, when detecting the strength of concrete test blocks, in order to ensure the accuracy of the detection, multiple test blocks need to be detected. But the current detection procedure is to place the test block under the rebound hammer, and then control the rebound hammer to move down to contact the test block for detection. However, such an operation is likely to result in a slow detection efficiency and an increased labor intensity due to the large number of test blocks to be detected and the many operation steps.

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0018] Embodiment: As Figures 1-5 shown, the present invention provides a concrete strength detector, including a horizontal plate 1. One end of the upper surface of the horizontal plate 1 is fixedly provided with a bracket 11 arranged in an inverted L shape. The top of the bracket 11 is fixedly installed with a cylinder 14. A moving plate 12 is slidably arranged up and down at the vertical end of the bracket 11. The output end of the cylinder 14 is fixedly arranged on the moving plate 12. A detector body 13 is installed on the side of the moving plate 12 away from the bracket 11. In the middle of the upper surface of the moving plate 12, a bottom plate 2 arranged in a circular shape is fixedly provided. A rotating plate 21 is rotatably arranged on the upper surface of the bottom plate 2. A placement groove 22 is penetrated and opened at the edge of the rotating plate 21. The detector body 13 is located directly above the placement groove 22 at the edge of the rotating plate 21. At the center of the lower surface of the rotating plate 21, a vertical first rotating rod 23 is fixedly provided. The first rotating rod 23 penetrates the bottom plate 2 and is rotatably arranged on the horizontal plate 1. At the bottom of the first rotating rod 23, a first gear 24 is fixedly provided. A vertical second rotating rod 25 is rotatably arranged on the lower surface of the horizontal plate 1 at the middle position between the bracket 11 and the first gear 24. A driving gear 26 is fixedly provided on the second rotating rod 25; the number of placement grooves 22 opened on the rotating plate 21 is twelve and they are evenly spaced. The driving gear 26 is one-twelfth of the first gear 24. When the driving gear 26 rotates one circle to drive the first gear 24 to rotate, it will drive the first gear 24 and the first rotating rod 23 to drive the rotating plate 21 to rotate by one-twelfth, thereby rotating the distance of one placement groove 22 interval, so that the test blocks in the subsequent placement grooves 22 can be intermittently moved directly below the detection head of the detector body 13.

[0019] A second gear 28 is fixedly provided below the driving gear 26 on the second rotating rod 25. A rotating shaft 291 is rotatably arranged on the lower surface of the horizontal plate 1 near the second gear 28. A half-face gear 29 meshing with the second gear 28 is fixedly provided at the bottom of the rotating shaft 291. A touch block 27 is fixedly provided on the upper surface of the driving gear 26. A touch switch 271 electrically connected to the cylinder 14 is installed on the lower surface of the horizontal plate 1 near the half-face gear 29. A driving motor 292 is installed on the upper surface of the horizontal plate 1 near the rotating shaft 291. The output end of the driving motor 292 is coaxially and fixedly arranged on the rotating shaft 291. The provided driving motor 292 can provide power for the operation of this device.

[0020] On the side of the moving plate 12 away from the support 11, a support plate 15 is slidably provided. The detector body 13 is installed on the support plate 15. On the side of the moving plate 12 facing the detector body 13, a vertically arranged chute 16 is opened. A slider 17 is slidably arranged in the chute 16. One end of the slider 17 is fixedly arranged on the cross plate 1. A vertically arranged lead screw 18 is slidably arranged in the chute 16. The slider 17 is threadedly arranged on the lead screw 18. When the lead screw 18 is driven to rotate, the lead screw 18 will drive the slider 17 to change the vertical height of the support plate 15 and the detector body 13. Thus, when some test blocks are shorter or taller, it can ensure that the detector body 13 can normally perform detection; a runner 19 is fixedly installed at the top of the lead screw 18. The arranged runner 19 can greatly facilitate the staff to drive the lead screw 18 to rotate and improve the operation convenience.

[0021] A discharge port 3 is penetrated and opened at the upper edge of the bottom plate 2. A discharge groove 31 is penetrated and opened on the upper surface of the cross plate 1 directly below the discharge port 3. The arranged discharge port 3 and the discharge groove 31 can automatically discharge the tested test blocks. A collection basket can be placed at the discharge groove 31 for convenient centralized collection.

[0022] Working principle: During use, the staff can put the concrete test blocks to be detected into the placement groove 22 at one time. At this time, the drive motor 292 can be started. The drive motor 292 can drive the rotating shaft 291 to rotate. At this time, the rotating shaft 291 drives the half gear 29 to rotate. First, the half gear 29 will drive the second gear 28 engaged with it to rotate 180 degrees. During this process, the drive gear 26 coaxial with the second gear 28 will drive the first gear 24 to rotate one-twelfth. At this time, the tested test block located below the detector body 13 will move to the next position, and the subsequent test block to be detected will move to directly below the detector body 13 to wait for detection. When the half gear 29 drives the second gear 28 to rotate half a circle, at this time, the drive gear 26 disengaged from the first gear 24 will move below the touch switch 271, and the touch block 27 will contact the touch switch 271. At this time, the air cylinder 14 will be started to push the moving plate 12 and the detector body 13 downward, so that the output end of the detector body 13 performs hardness detection on the test block to be detected. After the detection is completed, at this time, the half gear 29 rotates one circle and then drives the second gear 28 to rotate again. At this time, the second gear 28 will drive the drive gear 26 to disengage from the touch switch 271. The air cylinder 14 will drive the detector body 13 to move upward. At the same time, the subsequent drive gear 26 will rotate to the meshing position with the first gear 24. Thus, repeating the above operation again can make the multiple test blocks placed on the turntable 21 automatically move below the detector body 13 for detection. At the same time, the detector body 13 will also move downward to detect the test block, realizing automatic feeding and detection, improving the detection efficiency and reducing the labor intensity of the staff.

[0023] Obviously, those skilled in the art can make various modifications and variations to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model also intends to include these modifications and variations.
