Description

Technical Field

[0001] This invention belongs to the field of concrete impact testing technology, specifically a concrete impact testing device and method. Background Technology

[0002] Concrete is a brittle engineering material with poor energy absorption capacity. Under dynamic impact loads, its performance is easily compromised, and its structural stability and integrity are often severely damaged, potentially causing significant loss of life and property. Because impact loads have short loading times, the material strain rate is much higher than under static loading, and its deformation and failure modes differ from those under static conditions. Therefore, concrete of the same batch and grade usually needs to undergo impact resistance tests before use to predict its service life and impact resistance performance.

[0003] However, most existing testing devices have fixed counterweights, which makes it impossible to simulate different impact forces, thus limiting their application range. In addition, most existing testing devices can only simulate vertical downward impacts and cannot simulate oblique impacts, further limiting the overall application range of the device. To address these issues, this invention proposes a concrete impact resistance testing device and method. Summary of the Invention

[0014] The present invention also provides a method for testing the impact resistance of concrete, based on a concrete impact resistance testing device as described above, comprising the following steps: Step 1: When using this device, the operator controls the extension of the lifting rod of the test chamber through the controller, thereby driving the test chamber to rise and further placing the concrete test block on the top of the support plate. At this time, the controller controls the clamping motor to work, thereby making the clamping plate clamp the test block and making the test block located in the center of the support plate. Step Two: Next, the staff installs the required number of counterweights according to the impact energy to be applied. At this time, due to the action of the counterweight connecting groove and the counterweight connecting block, the counterweight locking groove and the counterweight locking rod, the upper and lower counterweights are locked together. Then, the test head replacement flange, pressure sensor and test head connector are tightened by bolts. At the same time, due to the action of the lowermost counterweight connecting block and the test head connecting groove, the lowermost counterweight locking rod and the test head locking groove, the test head connector and the lowermost test head are locked together, thereby achieving the required counterweight and ensuring the stability of the test head. Step 3: The controller further controls the electromagnet to be energized, thereby attracting the top counterweight. The rope winding motor then rotates the rope winding disc, causing the electromagnet to rise. When the support plate moves to the top, the locking rod and locking spring lock the support plate, thus ensuring the stability of the electromagnet. Finally, the lifting rod of the test chamber is reset, thus ensuring the airtightness of the test. Step 4: Further, the controller monitors the internal temperature of the test chamber through a temperature sensor. If a high temperature is required to be simulated, the controller controls the PTC heating plate to work. If a low temperature environment is required to be simulated, the controller controls the compressor, condenser, expansion valve and evaporator inside the outdoor unit to work, thereby cooling down. At the same time, the controller provides illumination to the inside of the test chamber through the lighting lamp and takes pictures of the surface deformation of the test block through an industrial camera. Step 5: At this point, the controller, through the coordination of the adjusting motor and the moving motor, enables the adjusting gear plate to rotate and the moving block to move, allowing the main barrel to be moved to any position on the top of the test block. Simultaneously, the tilt adjustment motor drives the connecting block to rotate, thus simulating impacts at different tilt angles. To simulate an impact in the direct direction, the main barrel is vertical, and the controller de-energizes the electromagnet. At this time, the weight of the counterweight, test head connector, and test head itself applies an impact to the test block. The pressure sensor captures the mechanical signal, and the industrial camera records the visual process of deformation and damage. Through time synchronization, the two achieve the corresponding analysis of "force action" and "shape change," thereby achieving the purpose of impact resistance performance testing. Step Six: When testing the tilt impact, the tilt angle adjustment motor controls the main barrel to rotate at a certain angle, and the angle sensor can measure the tilt angle. At the same time, the extension of the main barrel moving rod can drive the main barrel to descend, so that the main barrel is closer to the test block. At this time, due to the action of the main barrel support wheel and the auxiliary barrel support ball, the friction of the counterweight block when descending can be reduced, thereby ensuring the test accuracy. At the same time, by performing mechanical analysis, the magnitude of the tilt force can be determined, thereby determining the magnitude of the impact. Step 7: After the test is completed, the controller opens the test chamber and cleans the debris on the surface of the support plate to facilitate the next test.

[0015] Compared with the prior art, the beneficial effects of the present invention are: (1) This device can drive the clamping screw to rotate through the clamping motor, which in turn drives the clamping slider to rotate, thereby driving the clamping plate to move along the clamping groove, thus clamping the test block, thus adapting to test blocks of different sizes. At the same time, due to the function of the slag box, the sealing of the entire device can be guaranteed, and it is convenient to clean up the debris falling from the clamping groove, thus ensuring the cleanliness of the entire device. Meanwhile, this device uses a pressure sensor to capture mechanical signals and an industrial camera to record the visual process of deformation and damage. The two are linked in time to realize the corresponding analysis of "force action" and "shape change", thereby achieving the test purpose of impact resistance performance. (2) The test chamber can ensure the airtightness of the entire device, thereby preventing the flying of gravel during the test and ensuring the safety of the staff. At the same time, the heat insulation box can prevent heat loss. The temperature sensor can monitor the internal temperature of the test chamber. The compressor, condenser, expansion valve and evaporator inside the external unit can simulate the low temperature environment. The PTC heating plate can simulate the high temperature environment, thereby ensuring the test accuracy and improving the application range of the entire device. (3) This device uses an adjustment frame to position the adjustment gear plate. The adjustment motor can drive the adjustment gear to rotate, which in turn drives the adjustment gear plate to rotate, which in turn drives the connecting plate to rotate, which in turn drives the guide rail to change direction. At the same time, the moving motor drives the lead screw at its right end to rotate, which can drive the moving block to move, so that the test head can be moved to any position on the top of the test block. At the same time, the tilt angle adjustment motor can drive the connecting block to rotate, which can simulate tilting impact, thereby improving the application range of the entire device and ensuring the test effect. (4) This device uses a fixing plate to fix the auxiliary barrel. The auxiliary barrel is used to position the main barrel and can also position the counterweight, thereby ensuring the stability of the counterweight. The main barrel is a tilting impact guide, thereby preventing the test head from making parabolic motion during tilting impact, thus ensuring the accuracy of tilting impact and thus ensuring the impact test effect. The auxiliary barrel support ball and the main barrel support wheel cooperate to prevent the counterweight from rubbing against the auxiliary barrel and the main barrel, thereby reducing the resistance when the counterweight descends, thus ensuring the test accuracy and thus ensuring the impact test effect. (5) This device uses a locking head to position the support plate, and an electromagnet can magnetically attract the uppermost counterweight. When the electromagnet is de-energized, the counterweight falls directly, thereby reducing the resistance of the counterweight and ensuring the test accuracy and effect. The counterweight locking groove and the counterweight locking rod cooperate to prevent the counterweight from rotating, thereby preventing the upper counterweight connecting block from disengaging from the lower counterweight connecting groove, thus ensuring the connection between the upper and lower counterweights. At the same time, the test head can be replaced, thereby simulating impact points of different sizes and shapes, thereby improving the application range of the entire device.

Simultaneously, the controller 101 can drive the connecting block 306 to rotate via the tilt adjustment motor 307, from... The system can simulate impacts at different tilt angles. The angle sensor 313 monitors the rotation angle of the connecting block 306. To simulate an impact in a direct direction, the main barrel 4 is vertical. In this case, the controller 101 de-energizes the electromagnet 8. The weight of the counterweight 7, the test head connector 603, and the test head 6 then applies an impact to the test block. The pressure sensor 602 captures the mechanical signals, and the industrial camera 207 records the visual process of deformation and damage. These two sensors are synchronized in time to demonstrate the application of force. The analysis of the corresponding "shape change" achieves the purpose of impact resistance testing. When the test is conducted with an inclined impact, the tilt adjustment motor 307 controls the main barrel 4 to rotate at a certain angle. At the same time, the extension of the main barrel moving rod 402 can drive the main barrel 4 to descend, thereby bringing the main barrel 4 closer to the test block. This allows the test head 6 to move along the axis of the main barrel 4. At this time, the main barrel support wheel 404 reduces the friction between the auxiliary barrel 401 and the test head connector 603 and the counterweight 7. Simultaneously, the auxiliary barrel support ball 406 reduces the friction between the counterweight positioning block 701 and the counterweight connecting groove 704, thereby reducing the friction between the counterweight 7 and the test head connector 603 when descending, thus ensuring test accuracy. At the same time, mechanical analysis can determine the magnitude of the inclined force, thereby determining the impact magnitude. After the test is completed, the controller 101 controls the test chamber 2 to open and cleans the debris on the surface of the support plate 103, thus facilitating the next test.

[0023] Example 4, based on Example 1, is... Figure 10 , Figure 12 , Figure 14 , Figure 16 , Figures 18-19The rope 502 passes through the moving block 309 and the fixing plate 310 and is fixedly connected to the support plate 803. A displacement plate 801 is slidably connected to the outside of the displacement rod 802. The displacement plate 801 has a boss structure, and its inclined surface can fit against the inclined surface of the support plate 803, thus facilitating the smooth movement of the locking head 903 onto the inclined surface of the support plate 803. Movement of the displacement plate 801 allows the locking head 903 to disengage from the support plate 803, thereby releasing the electromagnet 8 and facilitating the magnetic attraction of the counterweight 7 on the top of the support plate 103. Each locking head 903 has a set of locking rods 901 fixed externally, and the locking rods 901 are made of alloy material. The locking rod 901 is used to position the locking head 903. Each set of locking rods 901 is externally slidably connected to a positioning plate 9, which is made of alloy material. The positioning plate 9 is used to position the locking rod 901. Each positioning plate 9 is fixedly connected to the auxiliary barrel 401. Each locking rod 901 is externally provided with a locking spring 902, which is elastic, allowing the two locking heads 903 to approach each other when no force is applied. Each auxiliary barrel 401 is provided with several auxiliary barrel grooves 405, which are used to position the auxiliary barrel support balls 406. Several auxiliary barrel support balls 406 are rotatably connected inside each auxiliary barrel groove 405. The auxiliary barrel support balls 406 are made of alloy material. Made of rubber, the auxiliary barrel support ball 406 is rotatable, thereby preventing the counterweight 7 from rubbing against the auxiliary barrel 401, thus reducing the resistance when the counterweight 7 descends, ensuring test accuracy, and thus ensuring the impact resistance test effect. Each main barrel 4 has several main barrel grooves 403 inside, which are used to position the main barrel support wheels 404. Several main barrel support wheels 404 are rotatably connected inside each main barrel groove 403. The main barrel support wheels 404 are made of rubber and are rotatable, thereby preventing the counterweight 7 from rubbing against the main barrel 4, thus reducing the resistance when the counterweight 7 descends, thus ensuring test accuracy, and thus ensuring the impact resistance test effect. To test the effect, several main barrel moving rods 402 are fixed to the top of the main barrel 4. These moving rods 402 are telescopic, thereby raising and lowering the main barrel 4 to facilitate the simulation of tilting impacts. The top of each main barrel moving rod 402 is fixedly connected to the fixed plate 310. Each auxiliary barrel support ball 406 is tightly fitted with the internal test head connector 603 and the counterweight 7. The uppermost counterweight 7 is magnetically connected to the electromagnet 8. Several counterweight positioning blocks 701, made of alloy material, are fixed to the outside of each counterweight 7. These positioning blocks 701 are used to position the counterweight 7. Each counterweight 7 has several counterweight locking slots 705 on its top.The counterweight locking groove 705 and the counterweight locking rod 708 cooperate to prevent the counterweight 7 from rotating, thereby preventing the upper counterweight connecting block 706 from disengaging from the lower counterweight connecting groove 704, thus ensuring the reliable connection between the upper and lower counterweights 7. Each counterweight 7 has a counterweight locking spring 702 fixed to its lower end. The counterweight locking spring 702 is elastic, so that the counterweight locking ring 703 is located at the lower end of the counterweight 7 when not under force. Each counterweight locking spring 702 has a counterweight locking ring 703 fixed to its bottom. 03 is made of alloy material. The counterweight locking ring 703 is used to position the counterweight locking rod 708. Several counterweight locking rods 708 are fixed at the bottom of each counterweight locking ring 703. The counterweight locking rods 708 are made of alloy material. The counterweight locking rods 708 are slidably connected to the counterweight 7. Each upper stabilizer 707 is slidably connected to each lower counterweight 7. Each upper counterweight connecting block 706 is engaged with its lower counterweight connecting groove 704. Each upper counterweight locking rod 708 is engaged with its lower counterweight locking rod. The test head connector 603 has several test head connecting slots 606 inside, which are used to position the lowest counterweight connecting block 706. The test head connector 603 has several test head locking slots 607 on its top, which are used to position the lowest counterweight locking rod 708. The test head connector 603 and the pressure sensor 602 have several adjusting slots 605 inside, which are used to position bolts, thereby ensuring that the test head connector 603 can be tightly fitted with the lowest counterweight connecting block 706. The stabilizing block 707 is tightly fitted to ensure the stability of the entire device. Several test head positioning blocks 604, made of alloy material, are fixed externally to the test head connector 603. These positioning blocks are used to position the test head connector 603. Each main barrel support wheel 404 can tightly engage with the test head positioning block 604 and the counterweight positioning block 701. The lowest counterweight connecting block 706 engages with the test head connecting groove 606, and the lowest counterweight locking rod 708 tightly engages with the test head locking groove 607. When a test is required, the operator opens the test chamber 2 via the controller 101. The controller 101 then controls the rope winding motor 501 to rotate the rope winding disc 5, thereby winding the rope 502 and causing the support disc 803 to rise. At this time, the inclined surface at the lower end of the support disc 803 allows the locking head 903 to move outward, thus bringing it close to the displacement disc 801. The controller 101 then controls the rope 502 to loosen. At this time, the inclined surfaces of the displacement disc 801 and the support disc 803 allow the locking head 903 to disengage from the support disc 803, thus allowing the... The electromagnet 8 descends to the bottom of the main barrel 4 and then falls to the top of the support plate 103. Next, the operator installs the required number of counterweights 7 according to the desired impact energy. The operator inserts the upper stabilizing block 707 into the lower counterweight 7 sequentially, and the upper counterweight connecting groove 704 into the lower counterweight connecting block 706. Due to the action of the counterweight locking spring 702, the counterweight locking ring 703 is movable. Further rotation of the two counterweights 7 locks both the upper and lower counterweights 7. When the upper counterweight locking rod 708 is inserted into the lower counterweight locking groove 705... Because the counterweight locking spring 702 and the counterweight locking ring 703 prevent the counterweight locking groove 705 from moving, the counterweight 7 is prevented from rotating, thus causing the upper and lower counterweights 7 to engage. Furthermore, bolts are used to tighten the test head replacement flange 601, the pressure sensor 602, and the test head connector 603. Simultaneously, the lowermost counterweight connecting block 706 and the test head connecting groove 606, the lowermost counterweight locking rod 708 and the test head locking groove 607 engage the test head connector 603 and the lowermost test head 6, achieving the required counterweight while ensuring the test... To ensure the stability of the test head 6, the controller 101 further controls the electromagnet 8 to be energized, thereby attracting the uppermost counterweight 7. The controller 101 then controls the electromagnet 8 to be energized, thereby magnetically attracting the uppermost counterweight 7. The rope winding motor 501 then rotates the rope winding disc 5, causing the electromagnet 8 to rise. When the support disc 803 moves to the top, the locking rod 901 and the locking spring 902 cause the two locking heads 903 to approach each other, thereby locking the support disc 803 and ensuring the stability of the electromagnet 8. Finally, the test chamber lifting rod 205 resets, ensuring the test's sealing and facilitating the test.

[0024] This embodiment of a concrete impact resistance test method, based on the concrete impact resistance test apparatus described above, includes the following steps: Step 1: When using this device, the operator controls the extension of the test chamber lifting rod 205 through the controller 101, thereby driving the test chamber 2 to rise and further place the concrete test block on the top of the support plate 103. At this time, the controller 101 controls the clamping motor 112 to work, thereby making the clamping plate 110 clamp the test block and making the test block located in the center of the support plate 103. Step Two: Further, the staff installs the required number of counterweights 7 according to the required impact energy. At this time, due to the action of the counterweight connecting groove 704, the counterweight connecting block 706, the counterweight locking groove 705, and the counterweight locking rod 708, the upper and lower counterweights 7 are engaged. The test head replacement flange 601, pressure sensor 602, and test head connector 603 are then tightened with bolts. At the same time, due to the action of the lowermost counterweight connecting block 706, the test head connecting groove 606, the lowermost counterweight locking rod 708, and the test head locking groove 607, the test head connector 603 and the lowermost test head 6 are engaged, thereby achieving the required counterweight and ensuring the stability of the test head 6. Step 3: The controller 101 further controls the electromagnet 8 to be energized, thereby attracting the uppermost counterweight 7. The rope winding motor 501 then rotates the rope winding disc 5, causing the electromagnet 8 to rise. When the support disc 803 moves to the top, the locking rod 901 and the locking spring 902 lock the support disc 803, thereby ensuring the stability of the electromagnet 8. Finally, the test chamber lifting rod 205 is reset, thereby ensuring the sealing of the test. Step 4: Further, the controller 101 monitors the internal temperature of the test chamber 2 through the temperature sensor 202. If a high temperature state needs to be simulated, the controller 101 controls the PTC heating plate 209 to work. If a low temperature environment needs to be simulated, the controller 101 controls the compressor, condenser, expansion valve and evaporator 204 inside the outdoor unit 201 to work, thereby cooling down. At the same time, the lighting lamp 208 provides illumination to the inside of the test chamber 2, and the industrial camera 207 captures the surface deformation of the test block. Step 5: At this time, the controller 101, through the coordination of the adjusting motor 303 and the moving motor 311, enables the adjusting gear 301 to rotate and the moving block 309 to move, thereby allowing the main barrel 4 to move to any position on the top of the test block. At the same time, the tilt adjustment motor 307 drives the connecting block 306 to rotate, thus simulating impacts at different tilt angles. If it is necessary to simulate an impact in the opposite direction, the main barrel 4 is vertical, and the controller 101 controls the electromagnet 8 to be de-energized. At this time, the weight of the counterweight 7, the test head connector 603, and the test head 6 can apply an impact to the test block. At this time, the pressure sensor 602 is responsible for capturing the mechanical signal, and the industrial camera 207 is responsible for recording the visual process of deformation and damage. The two are correlated in time to achieve the corresponding analysis of "force action" and "shape change", thereby achieving the purpose of impact resistance performance testing. Step Six: When testing the tilted impact, the tilt angle adjustment motor 307 controls the main barrel 4 to rotate at a certain angle, and the angle sensor 313 can measure the tilt angle. At the same time, the extension of the main barrel moving rod 402 can drive the main barrel 4 to descend, so that the main barrel 4 is close to the test block. At this time, due to the action of the main barrel support wheel 404 and the auxiliary barrel support ball 406, the friction of the counterweight 7 when descending can be reduced, thereby ensuring the test accuracy. At the same time, by performing mechanical analysis, the magnitude of the tilted force can be determined, thereby determining the magnitude of the impact. Step 7: After the test is completed, the controller 101 controls the test chamber 2 to open and cleans the debris on the surface of the support plate 103 to facilitate the next test.

10. A method for testing the impact resistance of concrete, based on the concrete impact resistance testing apparatus according to any one of claims 1-9, characterized in that: Includes the following steps: Step 1: When using this device, the staff controls the extension of the test chamber lifting rod (205) through the controller (101), thereby driving the test chamber (2) to rise, and further placing the concrete test block on the top of the support plate (103). At this time, the controller (101) controls the clamping motor (112) to work, thereby making the clamping plate (110) clamp the test block, and at the same time making the test block located in the center of the support plate (103); Step 2: Further, the staff installs the required number of counterweights (7) according to the required impact energy. At this time, due to the action of the counterweight connecting groove (704) and the counterweight connecting block (706), the counterweight locking groove (705) and the counterweight locking rod (708), the upper and lower counterweights (7) are locked together. Further, the test head replacement flange (601), pressure sensor (602) and test head connector (603) are tightened by bolts. At the same time, due to the action of the bottom counterweight connecting block (706) and the test head connecting groove (606), the bottom counterweight locking rod (708) and the test head locking groove (607), the test head connector (603) and the bottom test head (6) are locked together, thereby achieving the required counterweight and ensuring the stability of the test head (6). Step 3: The controller (101) further controls the electromagnet (8) to be energized, thereby attracting the uppermost counterweight (7). The rope winding motor (501) further rotates the rope winding disc (5), thereby causing the electromagnet (8) to rise. When the support disc (803) moves to the top, the support disc (803) can be locked due to the action of the locking rod (901) and the locking spring (902), thereby ensuring the stability of the electromagnet (8). The test chamber lifting rod (205) is then reset, thereby ensuring the sealing of the test. Step 4: Further, the controller (101) monitors the internal temperature of the test chamber (2) through the temperature sensor (202). If a high temperature state needs to be simulated, the controller (101) controls the PTC heating plate (209) to work. If a low temperature environment needs to be simulated, the controller (101) controls the compressor, condenser, expansion valve and evaporator (204) inside the outdoor unit (201) to work, thereby cooling down. At the same time, the lighting lamp (208) provides illumination to the inside of the test chamber (2), and the industrial camera (207) takes pictures of the surface deformation of the test block. Step 5: At this time, the controller (101) can make the adjusting gear plate (301) rotate by adjusting the motor (303) and moving motor (311), and at the same time make the moving block (309) move, so that the main barrel (4) can be moved to any position on the top of the test block. At the same time, the tilt adjustment motor (307) can drive the connecting block (306) to rotate, so that different tilt angles of impact can be simulated. If it is necessary to simulate the impact in the direct direction, the main barrel (4) is vertical, and the controller (101) controls the electromagnet (8) to be de-energized. At this time, the weight of the counterweight (7), the test head connector (603) and the test head (6) can apply impact to the test block. At this time, the pressure sensor (602) is responsible for capturing the mechanical signal, and the industrial camera (207) is responsible for recording the visual process of deformation and damage. The two are linked by time synchronization to realize the corresponding analysis of "force action" and "shape change", so as to achieve the test purpose of impact resistance performance. Step 6: When the test is tilted, the tilt angle adjustment motor (307) controls the main barrel (4) to rotate a certain angle, the angle sensor (313) can measure the tilt angle, and at the same time, the main barrel moving rod (402) can extend to drive the main barrel (4) to descend, so that the main barrel (4) is close to the test block. At this time, due to the action of the main barrel support wheel (404) and the auxiliary barrel support ball (406), the friction of the counterweight (7) when descending can be reduced, so as to ensure the test accuracy. At the same time, the magnitude of the tilting force can be determined by mechanical analysis, so as to determine the impact magnitude. Step 7: After the test is completed, the controller (101) controls the test chamber (2) to open and cleans the debris on the surface of the support plate (103) to facilitate the next test.
