Description

Technical Field

[0001] The utility model relates to the field of infrastructure engineering, in particular to a concrete strength detection device. Background Art

[0002] The announcement number is CN219417049U. The hydraulic propulsion cylinder is used to crush the sample through the compression table to make the pressure pusher on the pressure plate crush the sample. By replacing the pressure pushers of different shapes to simulate the sample under different force conditions, the disintegration parameters of the entire concrete sample are recorded.

[0003] When testing concrete samples, the above patent document requires manual movement of heavy concrete samples to be directly under the pressure pusher head, and the entire device is surrounded by sensors for testing, so the entire range of movement is relatively limited, which makes it inconvenient to move heavy concrete samples. At the same time, after the test, it is troublesome to clean the entire test position. Utility Model Content

[0030] The utility model is further described below in conjunction with the accompanying drawings:

[0031] like Figure 1-Figure 8 As shown, a concrete strength detection device includes a frame 4, a hydraulic rod 1 for pressing down concrete is arranged on the top of the frame 4, a collecting box 5 is slidably connected to the lower side of the frame 4, and also includes a squeezing mechanism 2, and a supporting mechanism 3 is arranged on the lower side of the squeezing mechanism 2;

[0032] In this embodiment: the extrusion mechanism 2 includes an extrusion frame 21, which is fixed to the telescopic part of the hydraulic rod 1, and a protective frame 23 is arranged on the extrusion frame 21. A pressure sensor 22 is arranged between the protective frame 23 and the extrusion frame 21. Convex seats 24 extending out of the frame 4 are fixed at both ends of the extrusion frame 21. Two arc-shaped convex heads 25 and a recess 26 are arranged at the end of the convex seat 24. The two arc-shaped convex heads 25 are respectively located at both sides of the recess 26. The telescopic part of the hydraulic rod 1 is used to push the extrusion frame 21, the pressure sensor 22 and the protective frame 23 downward, and the protective frame 23 is pressed against the top of the concrete to be detected. At the same time, the pressure sensor 22 is used to collect the data of the concrete being pressed;

[0033] In this embodiment: the supporting mechanism 3 includes two cleaning plates 36 hinged to each other, and the two cleaning plates 36 are both located in the middle of the frame 4. A lifting frame 35 is provided on the lower side of the hinged position of the two cleaning plates 36, and a centering plate 33 is provided on both sides of the cleaning plate 36. A flip frame 32 is provided on the side of the centering plate 33 away from the cleaning plate 36. The upper end of the flip frame 32 is rotatably connected with a flip plate 31, and a torsion spring 34 is provided at the connection position between the flip plate 31 and the flip frame 32 for allowing the flip plate 31 to reset after flipping. A T-shaped slider is provided at the bottom of the centering plate 33, and a T-shaped groove corresponding to the T-shaped slider is provided on the cleaning plate 36. As the convex seat 24 descends, the arc-shaped convex head 25 pushes the upper end of the flip plate 31 downward to flip the flip frame 32, and the flipped flip frame 32 pushes the two centering plates 33. The middle plates 33 approach each other and push the concrete to be tested to the center position of the entire device. When the convex seat 24 is located at the lower side of the flip plate 31, the lifting frame 35 drives the flip plate 31 to reset, and then pushes the two center plates 33 to move to the initial position. As the convex seat 24 continues to move downward, the recess 26 passes through the hook of the lifting frame 35 and engages with it, and then the extrusion frame 21 begins to pressurize the concrete through the pressure sensor 22 and the protective frame 23. When the test is completed, the extrusion frame 21 drives the convex seat 24 to lift up, and then drives the lifting frame 35 through the recess 26 to move it upward along the sliding groove 9. At this time, the lifting frame 35 will drive the two cleaning plates 36 to lift up the hinged position to form an arched structure, so as to clean the concrete waste on the cleaning plate 36.

[0034] In this embodiment: the frame 4 is fixed with a support plate at the cleaning plate 36 position, and the front and rear sides of the support plate are provided with a guide slot 7 for feeding the detected concrete waste into the collection box 5, the frame 4 is provided with a slide slot 6 at both ends of the guide slot 7 for facilitating the sliding of the end of the cleaning plate 36, the middle position of the support plate of the frame 4 is provided with a groove for placing the lifting frame 35, and the two ends of the groove are provided with a sliding slot 9 that penetrates the frame 4, and the frame 4 is provided with a slide slot 9 at both ends of the sliding slot 9 for facilitating the sliding of the lifting frame 35. The turning frame 32 is turned over by the turning notch 8, and a pin shaft for supporting the turning frame 32 is fixed in the groove of the frame 4, and the end of the lifting frame 35 extending out of the sliding notch 9 is provided with a hook that cooperates with the notch 26, and the support plate of the frame 4 is used to support the two horizontal cleaning plates 36. At the same time, the lifting frame 35 slides from the sliding notch 9 of the frame 4 to drive the hinged positions of the two cleaning plates 36 to arch, thereby facilitating the concrete waste residue on the two cleaning plates 36 to be discharged from the discharge notch 7 to the collection box 5 for collection.

[0035] Working principle: When in use, the telescopic part of the hydraulic rod 1 is used to push the extrusion frame 21, the pressure sensor 22 and the protective frame 23 downward. As the convex seat 24 descends, the arc-shaped convex head 25 first pushes the upper end of the flip plate 31 downward, and then the flip plate 31 is attached to both sides of the frame 4 and the flip frame 32 is flipped, and the flipped flip frame 32 pushes the center plate 33, and then the two center plates 33 are close to each other and push the tested concrete to the center position of the entire device. As the convex seat 24 continues to move downward, the upper end of the flip plate 31 is pushed downward. The center plate 33 stops moving at this time, and then the flip plate 31 flips outward under the downward push of the arc-shaped convex head 25, and then the arc-shaped convex head 25 and the flip plate 31 are separated from the push, and as the extrusion frame 21 continues to move downward, the convex seat 24 is located at the lower side of the flip plate 31, and the gravity on the lower side of the lifting frame 35 is greater than that on the upper side and drives the flip plate 31 to reset, and at the same time, the torsion spring 34 is used to make the flip plate 31 fit again on both sides of the frame 4, and then push the two center plates 33 to move to the initial position. At this time, as the convex seat 24 continues to move downward, the convex seat 24 is located at the lower side of the flip plate 31. The notch 26 moves downward, and the notch 26 passes through the hook of the lifting frame 35 and engages with it. Then the extrusion frame 21 starts to pressurize the concrete through the pressure sensor 22 and the protective frame 23, and uses the pressure sensor 22 to collect the data of the concrete being pressed. When the detection is completed, the extrusion frame 21 drives the convex seat 24 to pull up, and then drives the lifting frame 35 through the notch 26 to move upward along the sliding groove 9. At this time, the lifting frame 35 will drive the two cleaning plates 36 to be hinged to each other to form an arched structure, and the arched cleaning plate 36 will be lifted up. The cleaning plate 36 will slide the upper concrete slag onto the support plate of the frame 4. As the extrusion frame 21 continues to move upward, the notch 26 of the convex seat 24 will be disengaged from the lifting frame 35. At this time, the arched cleaning plate 36 will slide along the slide groove 6 to a horizontal state. In this process, the end of the cleaning plate 36 will push the concrete slag on the support plate. Then the concrete slag will pass through the outlet slot 7 into the collection box 5 for collection, and the convex seat 24 will pass through the flip plate 31 and be located on its upper side.

Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
