[0002] In the field of concrete construction, concrete core samples are an important basis for assessing concrete quality. Their accuracy and reliability are directly related to the safety and durability of building structures. Concrete core samples are usually cylindrical samples drilled from concrete on-site components. Their mechanical properties, such as compressive strength, elastic modulus, Poisson's ratio, etc., play an indispensable role in assessing the quality of concrete and its subsequent performance.

[0003] However, in the process of testing concrete core samples, a key step is to cut the core sample into specific sizes to facilitate various mechanical property testing tests. In this step, the performance of the cutting device directly determines the accuracy and efficiency of the core sample cutting. Unfortunately, the currently commonly used concrete core sample cutting device has significant deficiencies in fixing the core sample.

[0004] First, the structure of the device used to fix the concrete core sample on the commonly used cutting device is relatively complicated, which not only increases the manufacturing cost of the device, but also causes inconvenience during use. The complex fixing device is not only cumbersome to operate, but also easily causes the core sample to be not firmly fixed due to improper operation, thereby affecting the cutting accuracy.

[0005] Secondly, the existing cutting device does not fix the concrete core sample firmly enough, which is an urgent problem to be solved. During the cutting process, if the core sample is not firmly fixed, it is very easy to shake, which may not only lead to an uneven cutting surface, but also cause inaccurate cutting depth, seriously affecting the accuracy of the test results.

[0006] In addition, if the fixing device of the cutting device is not designed properly, it may also cause damage to the core sample itself, further reducing the reliability of the test result. Utility Model Content

Example 1

[0026] Please see attached Figure 1-4, This embodiment is a cutting device for reinforcing concrete core samples: comprising a frame 1, a cutter 2 is arranged inside the frame 1, a motor is installed on one side of the cutter 2, a guide rail 3 connected to the motor is fixedly installed on the top of the inner wall of the frame 1, a fixed structure 4 is arranged inside the frame 1, the fixed structure 4 comprises a support platform 5 fixedly installed on the frame 1, two support plates 6 are symmetrically arranged on the top of the support platform 5, two screws 7 are fixedly installed on the top of the support plate 6, a fastening frame 8 is movably installed between the two screws 7, and a nut 9 connected by thread is arranged on the screw 7. Through the setting of the fixed structure 4, the concrete core sample is conveniently fixed, the concrete core sample is placed on the two support plates 6, and then the two fastening frames 8 are inserted into the screw 7 and pressed down to fit the concrete core sample, and then the nut 9 is sleeved on the screw 7 and rotated, so that the fastening frame 8 descends along the thread between the screw 7 to fasten the fastening frame 8 fitted on the concrete core sample, effectively preventing the concrete core sample from shaking during cutting, and at the same time, the structure is simple and convenient to operate, and the cutting efficiency is effectively improved.

[0027] Two grooves 10 are provided on the support platform 5, and a plurality of movable blocks 11 connected to the support plate 6 are movably installed inside the grooves 10. A handle 12 is fixedly installed on the surface of the fastening frame 8, and a rubber pad 13 is fixedly sleeved on the handle 12. A support block 14 is fixedly installed on one side of the support platform 5, and a plurality of baffles 15 are fixedly installed on the top of the support block 14, and a dust suppression plate 16 is fixedly installed between adjacent baffles 15.

[0028] By setting the groove 10 and the moving block 11, the moving block 11 is connected to the bottom of the support plate 6. The moving block 11 moves in the groove 10 to adjust the distance between the two support plates 6, and then the distance between the two fastening frames 8 is adjusted, which is convenient for fixing concrete core samples of different lengths. After adjustment, the gravity of the concrete core sample is relied on to press up and down on the two support plates 6 to increase the friction between the two support plates 6 and the support platform 5 to fix the support plates 6 and prevent the two support plates 6 from moving; further, in order to prevent the movement of the moving block 11 in the support plate 6, a plurality of threaded holes distributed at intervals are provided on the support plate 6 on the side of the groove 10, and fixing bolts are installed in the threaded holes. The moving block 11 on the support plate 6 is pressed and fixed by the fixing bolts to ensure the stability of the moving block 11 relative to the support plate 6.

[0029] The handle 12 and the rubber pad 13 facilitate the picking up and lifting of the fastening frame 8 , and the support block 14 , the baffle 15 and the dust suppression plate 16 can suppress the dust generated by cutting and reduce the dust dispersion in the frame 1 .

[0030] By arranging the first movable door 17, the second movable door 18, the viewing window 19, the first fixed block 20, the plug rod 21 and the second fixed block 22, after the first movable door 17 and the second movable door 18 are closed on the frame 1, it is possible to effectively prevent the cutting dust from scattering outwards. At the same time, the arrangement of the viewing window 19 also facilitates viewing the process of concrete core cutting. After the first movable door 17 and the second movable door 18 are closed, the plug rod 21 on the first fixed block 20 is inserted into the second fixed block 22. The second fixed block 22 is provided with a socket that cooperates with the plug rod 21. The plug rod 21 and the socket can be movably connected or can be clamped. Further, in order to stably fix the closed first movable door 17 and the second movable door 18, a threaded groove can be provided on the plug rod 21, which is tightened by relying on the threaded connection between the plug rod 21 and the second fixed block 22 to prevent it from loosening and opening.

[0031] Through the setting of the operation panel 23, the operation panel 23 is electrically connected to the guide rail 3 in the frame 1 and the motor on one side of the cutter 2, which is convenient for the staff to centrally control the start-up. At the same time, it is set on one side of the frame 1, which is easier for the staff to operate. Example 2

[0033] The adjusting screw 24 is located in the groove 10 of the support platform 5. The adjusting screw 24 is rotatably connected to the support platform 5. The two adjusting screws 24 rotate synchronously. The two moving blocks 11 on the same adjusting screw 24 are located in two thread grooves with different rotation directions. When the adjusting screw 24 is rotated, the two moving blocks 11 are relatively close to or far away from each other, so that the two moving blocks 11 can be adjusted synchronously, thereby improving the adjustment efficiency of the support plate 6 on the support platform 5 and facilitating the user's operation. At the same time, it plays a good fixing role on the moving block 11 after it moves, and there is no need to reinforce it with fixing bolts.

[0034] The overall workflow of the device when in use is as follows: the concrete core sample is placed on the two support plates 6, and then the two fastening frames 8 are inserted into the screw rod 7 and pressed down to fit the concrete core sample, and then the nut 9 is sleeved on the screw rod 7 and rotated, so that it descends along the thread between the screw rod 7 to fasten the fastening frame 8 fitted on the concrete core sample, and then the motor is started to drive the cutter 2 to rotate, and then the starting guide rail 3 drives the cutter 2 to approach the concrete core sample for cutting; specifically, when fixing the concrete core sample, the spacing between the two support plates 6 can be adjusted by setting the groove 10 and the moving block 11, and then the spacing between the two fastening frames 8 is adjusted, so that it is convenient to fix concrete core samples of different lengths, and the fastening frame 8 is convenient to pick up and lift by setting the handle 12 and the rubber pad 13, and the dust generated by the cutting can be suppressed by setting the support block 14, the baffle 15 and the dust suppression plate 16, so as to reduce the dust from floating in the frame 1.
