Abstract
Description
Technical Field
[0001] The present application relates to the technical field of testing equipment, and in particular to a concrete flexural strength testing device. Background Art
[0002] The maximum load that concrete can withstand per unit area under bending pressure is called concrete flexural strength. Generally, concrete flexural strength is about 1 / 5 to 1 / 10 of its cubic compressive strength and 1.5 to 3.0 times of its splitting tensile strength. It can generally be calculated based on the breaking load during flexure, the distance between the two supporting points (the bottom action point), the width of the specimen section, and the height of the specimen section.
[0003] The existing concrete flexural strength testing device generally includes two supporting points and a testing head. During the test, due to the crushing of the concrete test piece, its debris is easily left on the supporting position. Generally, when the test piece is broken, the larger debris is easy to clean, but the smaller debris needs to be cleaned by the operator to prevent the concrete bottom from being uneven due to the presence of residue after the concrete test piece is placed in the next test, thereby affecting the test results. For this reason, we propose a concrete flexural strength testing device that is easy to clean. Summary of the invention

[0026] Example:
[0027] Reference Figure 1-4The present embodiment proposes a concrete flexural strength testing device, including a mounting platform 3 for mounting a workpiece to be tested and a testing head 2 for testing. The mounting platform 3 is provided with a driving structure, a supporting structure and a shielding structure. The workpiece to be tested is placed on the supporting structure, and the supporting structure includes two supporting sites. The driving structure is suitable for adjusting the distance between the two supporting sites. The shielding structure is located outside the two supporting sites when the two supporting sites are at a maximum supporting distance. When the driving structure drives the two supporting sites to move to a distance exceeding the maximum supporting distance, the shielding structure is suitable for removing the workpiece to be tested remaining on the supporting structure. After the test is completed, the driving structure is used to drive the two supporting sites to move to a distance exceeding the maximum supporting distance. At this time, the residue can be automatically removed to facilitate the next test, which can reduce the manual cleaning process and simplify the operation process.
[0028] The driving structure includes a double-headed screw 7 and a motor 13, and the supporting structure includes sliders 8 threadedly connected on both sides of the double-headed screw 7, and the supporting position is located at the top of the slider 8. The motor 13 drives the double-headed screw 7 to rotate so that the sliders 8 on both sides move closer or farther away at the same time. In the initial state, the center of the line connecting the sliders 8 on both sides corresponds to the bottom of the detection head 2. During detection, the force point on the top of the test piece is at the action point of the detection head 2, that is, at the center of the two supporting positions, which is easy to calculate later.
[0029] The detection head 2 is arranged on the frame 1 . Generally, when the frame 1 is installed, it is preferred that the detection head 2 is located at the center line of the mounting platform 3 .
[0030] The driving structure further includes a guide rod 9 and a guide portion 10, and a support frame 6 is provided between the corresponding slider 8 and the guide portion 10 to form a complete guide structure.
[0031] A limit groove 11 is provided in the middle of the support frame 6, and the test piece is located in the limit groove 11 during detection; the side of the limit groove 11 is provided with an anti-skid texture. The setting of the limit groove 11 can effectively prevent the test piece from shifting during detection, and the anti-skid texture further increases stability.
[0032] The shielding structure includes a blanking plate 4 arranged on both sides of the top surface of the mounting table 3, and an adjustment space of the support structure is formed between the two blanking plates 4. After installation, the bottom surface height of the workpiece to be tested is less than the height of the top surface of the blanking plate 4, and it is best that the top surface of the support frame 6 fits the bottom surface of the blanking plate 4. After the experiment is over, the motor 13 drives the double-headed screw 7 to rotate, so that the two sliders 8 move toward the blanking plate 4 until the blanking plate 4 acts on the residue of the workpiece to be tested on the support frame 6, and the blanking plate 4 blocks the residue, and the residue falls. At the same time, since the top surface of the support frame 6 and the bottom surface of the blanking plate 4 fit, it can be ensured that the residue on the support frame 6 is completely blocked, thereby ensuring that no material remains on the support frame 6.
[0033] Mounting grooves for accommodating the double-headed screw 7 and the guide rod 9 are provided on both sides of the mounting platform 3. The top and bottom surfaces of the slider 8 are both fitted in the mounting grooves. The portion of the mounting groove in the adjustment space is provided with a baffle 12. The baffle 12 is provided at the top and bottom of the outer side of the mounting groove. A gap of the same thickness as the support frame 6 is left between the two baffles 12. The baffle 12 is provided without hindering the movement and adjustment of the slider 8 and the support frame 6, and can prevent the splashing of residues into the mounting groove during detection as much as possible.
[0034] Two blanking plates 4 are also provided at the bottom of the mounting platform 3, and a receiving portion 5 is provided between the pair of blanking plates 4 at the bottom. The position where the receiving portion 5 connects with the blanking plate 4 is an inclined surface. The setting of the inclined surface can prevent the residual blocks from falling directly during blanking to a certain extent, so as to avoid damage to the connecting portion 5.
[0035] The front and back sides of the material receiving portion 5 are both open in design, and the open design facilitates the subsequent cleaning of residues.
[0036] The driving structure can also be set as an electric guide rail and a pair of guide blocks. The electric guide rail is suitable for controlling a pair of guide blocks to move to a set position. The electric guide rail can select a linear guide rail. Since there is a need to drive a pair of guide blocks to move in opposite directions during the adjustment process, two linear guide rails can be set here, and the two linear guide rails are driven separately to meet the adjustment requirements.
[0037] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application. The present application may have various changes and improvements without departing from the spirit and scope of the present application, and these changes and improvements fall within the scope of the present application for which protection is sought. The scope of protection claimed by the present application is defined by the attached claims and their equivalents.
