[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1 to 6 The present invention will describe the above technical solution in detail through the following embodiments:

[0027] A rebar testing device for construction engineering includes: a frame 1; first moving blocks 2 are slidably connected to both sides of the frame 1, and second moving blocks 3 are slidably connected to the side of the frame 1 away from the first moving blocks 2; two first clamping plates 4 are fixedly connected to one side of the first moving blocks 2; a second clamping plate 5 is disposed between the two first clamping plates 4; the second clamping plate 5 is fixedly connected to the second moving blocks 3; a rebar body 6 is disposed between the first clamping plates 4 and the second clamping plates 5; and matching triangular grooves 7 are provided on both the first clamping plates 4 and the second clamping plates 5 near the rebar body 6; the bottom of the frame 1 is provided with... A linkage mechanism 8 for quickly fixing the steel bar body 6 of diameter; a moving mechanism 9 for detecting the steel bar body 6 is set on the top of the frame 1. The user places the steel bar body 6 between the first clamping plate 4 and the second clamping plate 5, and then controls the first moving block 2 and the second moving block 3 to move towards the steel bar body 6 simultaneously through the linkage mechanism 8. The first moving block 2 drives the first clamping plate 4, and the second moving block 3 drives the second clamping plate 5. The first clamping plate 4 and the second clamping plate 5 clamp and fix the steel bar body 6 through the cooperation of the triangular groove 7. Then, the moving mechanism 9 performs downward pressure detection on each section of the steel bar body 6.

[0028] like Figure 4 and Figure 5As shown, the linkage mechanism 8 includes: a dual-axis motor 10 fixedly connected to the bottom center of the frame 1; first bevel gears 11 fixedly connected to both output ends of the dual-axis motor 10; second bevel gears 12 meshing with the ends of the first bevel gears 11 away from the dual-axis motor 10; a rotating shaft 13 fixedly connected to the center of the second bevel gears 12; the top end of the rotating shaft 13 passing through the connecting frame 15 and extending to the circular plate 14; the connecting frame 15 being fixedly connected to the frame 1; and the circular plate 14 being fixedly connected to the rotating shaft 13; two linkage rods 16 rotatably connected to the top of the circular plate 14; the ends of the linkage rods 16 away from the circular plate 14 respectively connecting to the first moving block 2. The second moving block 3 is rotatably connected, and the dual-axis motor 10 is started. The output end of the dual-axis motor 10 drives the first bevel gear 11, the first bevel gear 11 drives the second bevel gear 12, the second bevel gear 12 drives the rotating shaft 13, the rotating shaft 13 drives the circular plate 14, and the circular plate 14 rotates while driving the linkage rod 16. The linkage rod 16 pulls the first moving block 2 and the second moving block 3 respectively, so that the first moving block 2 and the second moving block 3 move closer to each other. The first moving block 2 drives the first clamping plate 4, and the second moving block 3 drives the second clamping plate 5. While the first clamping plate 4 and the second clamping plate 5 move closer to each other, the steel bar body 6 is clamped and fixed through the triangular groove 7.

[0029] like Figure 3 As shown, the first moving block 2, the second moving block 3, and the first clamping plate 4 are all provided with sliding grooves 17 on both sides. The frame 1 is fixedly connected with matching slide bars 18 near the sliding grooves 17. The first moving block 2, the second moving block 3, and the first clamping plate 4 are all slidably connected to the slide bars 18 through the sliding grooves 17, which can limit the first moving block 2, the second moving block, and the first clamping plate 4, so that the first moving block 2, the second moving block, and the first clamping plate 4 can slide flexibly horizontally inside the frame 1.

[0030] like Figure 6As shown, the moving mechanism 9 includes: a fixed frame 19 fixedly connected to the top of the frame 1; an adjusting block 20 is provided inside the fixed frame 19; a screw 21 is threadedly connected inside the adjusting block 20; one end of the screw 21 is rotatably connected to the fixed frame 19; the other end of the screw 21 passes through the fixed frame 19 and extends to the motor 22; the motor 22 is fixedly connected to the fixed frame 19; and the screw 21 is fixedly connected to the output end of the motor 22. Two hydraulic cylinders 23 are fixedly connected to the bottom of each adjusting block 20; the extension and retraction ends of the hydraulic cylinders 23 are fixedly connected to each other. A pressure sensor 24 is fixedly connected to the bottom of the two pressure sensors 24 via a pressure block 25. The motor 22 is started, and the output end of the motor 22 drives the screw 21. The screw 21 drives the adjusting block 20. While the adjusting block 20 moves, it drives the hydraulic cylinder 23. The extension end of the hydraulic cylinder 23 drives the adjusting block 20 via the pressure sensor 24. Then the hydraulic cylinder 23 is started, and the extension end of the hydraulic cylinder 23 extends outward and drives the pressure block 25 via the pressure sensor 24. In turn, the pressure block 25 presses down on the steel bar body 6 for detection.

[0031] like Figure 6 As shown, both sides of the screw 21 are provided with slide rods 26, and both ends of the slide rods 26 are fixedly connected to the fixed frame 19. The adjusting block 20 is slidably connected to the slide rods 26, which can limit the adjustment block 20 and make the adjusting block 20 slide flexibly horizontally.

[0032] like Figure 1 As shown, a control box 27 with an internal display screen is fixedly connected to the top side of the frame 1. It can not only control the device, but also observe the detection data of the steel bar body 6 through the display screen.

[0033] like Figure 1 As shown, the bottom of each connecting frame 15 is fixedly connected to a support frame 28, which improves the stability of the device placement.

[0034] Working principle: The user places the steel bar body 6 between the first clamping plate 4 and the second clamping plate 5, and then starts the dual-axis motor 10. The output end of the dual-axis motor 10 drives the first bevel gear 11, the first bevel gear 11 drives the second bevel gear 12, the second bevel gear 12 drives the rotating shaft 13, the rotating shaft 13 drives the circular plate 14, and the circular plate 14 rotates while driving the linkage rod 16. The linkage rod 16 pulls the first moving block 2 and the second moving block 3 respectively, so that the first moving block 2 and the second moving block 3 move closer to each other. The first moving block 2 drives the first clamping plate 4, the second moving block 5, and the second moving block 5 move closer to each other. 3. When the second clamping plate 5, the first clamping plate 4, and the second clamping plate 5 move closer to each other, the steel bar body 6 is clamped and fixed through the triangular groove 7. This not only simplifies the steel bar clamping process and improves the efficiency of steel bar clamping, but also enables clamping and fixing of steel bars of different diameters, improving practicality. It solves the problem that although the existing steel bar testing devices for construction engineering can clamp and fix both ends of the steel bar, they require rotating the adjusting column in sequence to clamp the steel bar, resulting in a slow clamping speed, a complicated clamping process, and low work efficiency.

[0035] The motor 22 is started, and its output drives the screw 21. The screw 21 drives the adjusting block 20, which in turn drives the hydraulic cylinder 23. The extension and retraction end of the hydraulic cylinder 23 drives the adjusting block 20 through the pressure sensor 24. Then, the hydraulic cylinder 23 is started, and its extension and retraction end extends outward, driving the pressure block 25 through the pressure sensor 24. The pressure block 25 then presses down on the steel bar body 6 for detection. This allows for the detection of different parts of the steel bar, solving the problem that existing steel bar detection devices used in construction engineering can only detect the middle part of the steel bar, resulting in inaccurate detection data.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
