Abstract
Description
Technical Field
[0001] The utility model relates to a concrete performance detection device, in particular to a high-ductility concrete performance detection device. Background Art
[0002] After high-ductility concrete blocks are produced, they need to be strength-tested to determine whether the quality of the high-ductility concrete meets the relevant requirements. The typical method for testing concrete block strength is to place the block on the work surface of a testing device and activate the pressure testing device. The device's telescopic structure drives the lower pressure plate to press down on the block, thereby testing the concrete block's strength.
[0003] During the process of placing the concrete blocks, if there is a certain offset between the placement position of the concrete blocks and the detection position, it will cause a certain error in the strength detection result. Utility Model Content
[0004] The main purpose of the utility model is to provide a high-ductility concrete performance detection device, which solves the technical problem that the existing detection device is prone to position deviation when placing concrete blocks, thereby causing large errors in the detection results.
[0005] In order to achieve the above-mentioned purpose, the utility model provides a high-ductility concrete performance testing device, comprising a workbench, a fixing structure and a testing structure;
[0006] The fixed structure includes a swing arm, a swing rod, a first bevel gear, a second bevel gear, a motor and a clamping plate. The middle part of the swing arm is rotatably connected to the bottom surface of the workbench, and the two ends of the swing arm are rotatably connected to the swing rod. The end of the swing rod away from the swing rod is rotatably connected to the clamping plate. The clamping plate extends through the workbench to the top of the workbench. The middle part of the swing arm is provided with a first bevel gear, the first bevel gear is meshed with the second bevel gear, the second bevel gear is connected to the output end of the motor, and the motor is fixedly connected to the workbench.
[0007] The detection structure is located on the top of the workbench.
[0008] As a preferred solution, the workbench is provided with a limiting opening that passes through the table top, and the workbench is also provided with a sliding groove.
[0009] As a preferred solution, a connecting block is provided at one end of the bottom of the splint, and a slider is provided at the other end of the splint. The connecting block is arranged in the limit opening, the connecting block is rotatably connected to the rocker arm, and the slider is arranged in the slide groove.
[0010] As an optimal solution, the detection structure includes a support frame, a hydraulic cylinder and a lower pressure plate. The support frame is fixedly connected to the top of the workbench, the support frame is fixedly connected to one end of the hydraulic cylinder, the hydraulic cylinder extends toward the workbench surface, and the other end of the hydraulic cylinder is fixedly connected to the lower pressure plate.
[0011] As a preferred solution, the workbench surface is further provided with a dust suction port, which is connected to a vacuum cleaner.
[0012] The beneficial effects achieved by the utility model are:
[0013] This new embodiment uses a fixed structure to fix the concrete blocks, making the placement of the concrete blocks more accurate. In the fixed structure, the two rocker arms are driven to move by the rotation of the rocker arms, and the movement of the rocker arms drives the movement of the splints. The movements of the two rocker arms are symmetrical, which ensures that the positions of the symmetrical planes of the two splints remain unchanged, thereby limiting the position of the concrete blocks, placing the concrete blocks in the nearest detection area, and improving the accuracy of the detection.

[0020] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0021] like Figure 1-Figure 3As shown, the utility model discloses a high ductility concrete performance testing device, comprising a workbench 1, a fixing structure 2 and a testing structure 3. The workbench 1 comprises a table top and four supporting legs, and the four supporting legs are fixedly arranged around the bottom of the table top.
[0022] The fixed structure 2 is used to clamp and fix the concrete block. The fixed structure 2 includes a swing arm 21, a rocker rod 22, a first bevel gear 23, a second bevel gear 24, a motor 25, and a clamping plate 26. The middle portion of the swing arm 21 is rotatably connected to the middle portion of the workbench 1 surface. Each end of the swing arm 21 is rotatably connected to a rocker rod 22. The end of the rocker rod 22 away from the swing arm 21 is rotatably connected to the bottom end of the clamping plate 26. As a form of rotational connection, a connecting block 261 is fixed to the bottom end of the clamping plate 26. The workbench 1 is provided with two limiting openings 11 that pass through the surface of the workbench. These two limiting openings 11 are rotationally symmetrical with the center point of the surface as the rotation center. The connecting block 261 is inserted into the limiting opening 11, and the bottom of the connecting block 261 is rotatably connected to the rocker rod 22. The other end of the splint 26 is slidably connected to the workbench 1. As a sliding connection method, the workbench 1 is provided with two slide grooves 12. The two slide grooves 12 are rotationally symmetrical with the center point of the table surface as the rotation center. The extension direction of the slide groove 12 is the same as the extension direction of the limit opening 11. The other end of the splint 26 is fixed with a slider 262, which is clamped in the slide groove 12.
[0023] A first bevel gear 23 is fixedly connected to the center of the swing arm 21. When the first bevel gear 23 rotates, it can drive the swing arm 21 to rotate. The first bevel gear 23 is engaged with the second bevel gear 24. The second bevel gear 24 is connected to the output end of the motor 25. The rotation of the output end of the motor 25 can drive the second bevel gear 24 to rotate. The motor 25 is fixed to the bottom of the workbench 1.
[0024] The detection structure 3 is set on the top of the workbench 1. The detection structure 3 includes a support frame 31, a hydraulic cylinder 32 and a lower pressure plate 33. The support frame 31 is fixedly connected to the workbench 1. The support frame 31 spans the workbench 1. The center point of the crossbar of the support frame 31 coincides with the center point of the workbench 1 surface for the best result. The hydraulic cylinder 32 is fixedly set at the center point of the crossbar of the support frame 31. The hydraulic cylinder 32 extends downward, and the bottom of the hydraulic cylinder 32 is fixedly connected to the lower pressure plate 33. The detection structure 3 is a prior art. This section only briefly introduces the main structure of the detection structure 3, and the working principle of the detection structure 3 is not repeated here.
[0025] During use, the concrete block is first placed on the workbench 1, and then the motor 25 is started. The motor 25 drives the second bevel gear 24 to rotate, and the second bevel gear 24 drives the first bevel gear 23 to rotate. The first bevel gear 23 drives the swing arm 21 to rotate, and the swing arm 21 pulls the swing rod 22 to move, and the swing rod 22 supports the clamping plate 26 to move, so that the clamping plate 26 clamps and adjusts the position of the concrete block until the concrete block stops moving, and the motor 25 is turned off. Then, the detection mechanism 3 is started to detect the strength of the concrete block.
[0026] In order to dissipate the dust generated when the concrete blocks are crushed as quickly as possible, a dust suction port 4 can be provided on the table top of the workbench 1. The dust suction port 4 is connected to a dust collector (not shown in the figure). The dust collector is also a prior art. The dust collector can adopt an existing mature product on the market, which will not be described in detail in this article.
[0027] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. 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.
