DETAILED DESCRIPTION

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-7 , an embodiment provided by the present invention:

[0027] A device for detecting the strength of durable concrete, comprising:

[0028] The main body includes a strength detection host 1, a control component 11 is fixedly connected to the surface of the strength detection host 1, and a rebound hammer 12 and an ultrasonic probe 13 are set on the side of the strength detection host 1. The strength detection device combines the ultrasonic method and the rebound method. The rebound hammer 12 and the ultrasonic probe 13 measure the propagation speed and rebound value of the ultrasonic wave in the concrete, and comprehensively infer the compressive strength of the durable concrete. The rebound hammer 12 and the ultrasonic probe 13 are existing instruments and can be connected to the surface of the strength detection host 1 through a line. The control component 11 consists of a button module and a display module.

[0029] The covering mechanism includes a cover plate 2, which is movably connected to the surface of the strength detection host 1. The surface of the strength detection host 1 is fixedly connected with a fixed block 21 and a spring sheet 28.

The surface of the movable rod 22 is fixedly connected with a rotating block 24. The surface of the connecting shaft 25 is fixedly connected with a baffle 26. The surface of the connecting shaft 25 is rotatably connected with a rotating drum 27. The cover plate 2 is made of a transparent and visible material, so that the staff can clearly see the data on the control component 11 when testing through the rebound tester 12 and the ultrasonic detection head 13, and the cover plate 2 plays a shielding and protective role for the control component 11.

[0030] Furthermore, the size of the cover 2 is larger than the size of the control component 11, and two groups of fixed blocks 21 and movable rods 22 are provided. The two groups of fixed blocks 21 are installed on both sides of the strength detection host 1, and the two groups of movable rods 22 are installed on both sides of the cover 2. The number of each group of fixed blocks 21 is two, and the movable rods 22 are movably connected to the surface of the fixed blocks 21. Each group of fixed blocks 21 is fitly connected to the two ends of the movable rods 22. Under the connection of the fixed blocks 21 and the movable rods 22, the connection effect of the strength detection host 1 and the cover 2 can be achieved, so that the cover 2 can be movable on the surface of the strength detection host 1.

[0031] Furthermore, the diameter of the rotating hole 23 is the same as the diameter of the rotating block 24. Two groups of rotating blocks 24 are provided. The two groups of rotating blocks 24 are installed at both ends of the movable rod 22. The rotating blocks 24 are rotatably connected to the surface of the rotating hole 23. Under the connection between the rotating hole 23 and the rotating block 24, the cover 2 can be rotated around the rotating block 24, so that the staff can open the cover 2 when operating the control component 11, and close the cover 2 when not operating.

[0032] Furthermore, one end of the connecting shaft 25 is fixedly connected to the surface of the cover plate 2, and the other end of the connecting shaft 25 is fixedly connected to the surface of the baffle 26. The diameter of the baffle 26 is larger than the inner diameter of the rotating drum 27. There are two groups of rotating drums 27, and the two groups of rotating drums 27 are snap-connected on both sides of the spring sheet 28. The rotating drum 27 can be installed and rotated through the connecting shaft 25. Under the action of the baffle 26, the rotating drum 27 can be limited to the surface of the connecting shaft 25, and the diameter of the connecting shaft 25 is the same as the inner diameter of the rotating drum 27, and the length of the rotating drum 27 is the same as the length of the connecting shaft 25, and the spring sheet 28 is elastic and can be elastically changed.

[0033] Furthermore, the surface of the strength detection host 1 is provided with an anti-slip mechanism, which includes a connecting block 3, which is fixedly connected to the bottom surface of the strength detection host 1, and a rubber pad 31 is abutted and connected on the surface of the connecting block 3. A plug-in slot 32 and a snap-fit ​​slot 34 are provided on the surface of the connecting block 3. A plug-in block 33 is fixedly connected to the surface of the rubber pad 31, and a snap-fit ​​block 35 is fixedly connected to the surface of the plug-in block 33. The rubber pad 31 can be installed and connected to the strength detection host 1 through the connecting block 3. The side of the plug-in block 33 close to the plug-in slot 32 is arc-shaped and has the same diameter as the diameter of the plug-in slot 32.

[0034] Furthermore, four groups of connecting blocks 3 are provided, and the four groups of connecting blocks 3 are installed at the four ends of the strength detection host 1. The diameter of the rubber pad 31 is the same as the diameter of the connecting block 3. Two groups of plug-in blocks 33 and snap-fit ​​grooves 34 are provided. Multiple groups of anti-slip grooves arranged in a linear array are provided on the surface of the rubber pad 31, thereby making the anti-slip effect of the strength detection host 1 better.

[0035] Furthermore, two groups of plug-in blocks 33 are installed on both sides of the rubber pad 31, and two groups of snap-fit ​​grooves 34 are opened on both sides of the plug-in groove 32. The plug-in blocks 33 are plugged and connected to the surface of the plug-in groove 32, and the snap-fit ​​blocks 35 are snap-fit ​​and connected to the surface of the snap-fit ​​groove 34. The surface of the snap-fit ​​block 35 is hemispherical. Under the connection of the snap-fit ​​groove 34 and the snap-fit ​​block 35, the connection effect of the plug-in groove 32 and the plug-in block 33 can be achieved, and then the connection effect of the connection block 3 and the rubber pad 31 can be achieved.

[0036] Working principle: When using and operating the detection device, first bend the cover plate 2 so that it rotates around the rotating block 24. The rotating block 24 rotates on the surface of the rotating hole 23, and the movable rod 22 moves on the surface of the fixed block 21. At this time, the two groups of rotating cylinders 27 rotate around the connecting shafts 25 to which they are connected due to the extrusion and friction with the spring sheet 28. The spring sheet 28 undergoes elastic deformation after being squeezed to cancel the engagement between the spring sheet 28 and the two groups of rotating cylinders 27. The cover plate 2 is rotated to the side away from the control component 11, thereby exposing the control component 11, so that the staff can operate it conveniently.

[0037] When using the device to test the strength of durable concrete, first align the two sets of plug-in blocks 33 installed on the rubber pad 31 with the plug-in slots 32 and insert them therein. After being squeezed, the snap-fit ​​blocks 35 cause the plug-in blocks 33 to elastically deform, and the snap-fit ​​blocks 35 rest against the plug-in slots 32. Then, the rubber pad 31 is rotated. When the positions of the snap-fit ​​blocks 35 and the snap-fit ​​slots 34 are aligned, the plug-in blocks 33 restore their elastic deformation and drive the snap-fit ​​blocks 35 to engage with the surface of the snap-fit ​​slots 34 to complete the installation of the rubber pad 31. Then, the strength testing host 1 is placed on the testing platform through the rubber pad 31.

[0038] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
