[0002] Bridge structural components are the key parts that make up a bridge and bear loads. They work together to ensure the stability and safety of the bridge.

[0003] To ensure the safety of bridge structural components, strength testing of their components is necessary. This requires the use of appropriate strength testing devices. Pressure is applied to the bridge structural components using pressure blocks on the testing device, and the strength is determined by the deformation of the components under different pressures. However, when some bridge structural components have irregular shapes, such as cement blocks, the load applied by the pressure blocks cannot be evenly distributed to the specimen, reducing the accuracy of the strength test. Therefore, to ensure accurate testing, the specimens need to be reshaped. However, some existing strength testing devices cannot assist in reshaping the specimens, requiring workers to perform this task separately, increasing their workload. Summary of the Invention

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0020] This invention provides a structural component strength testing device, such as... Figure 1-10As shown, the structural component strength testing device includes: a mounting frame 1; a placement frame 2 symmetrically arranged on the mounting frame 1, wherein a placement plate 3 is provided inside the placement frame 2 for placing bridge structural components; a first electric telescopic rod 4 fixedly installed on the mounting frame 1, wherein a pressure block 5 for applying pressure to the bridge structural components is fixedly installed on the output shaft of the first electric telescopic rod 4; and a trimming mechanism assembled on the mounting frame 1 for trimming the shape of the bridge structural components.

[0021] In this embodiment, the device is first equipped with a Siemens SIMATIC S7-1500 controller. The controller controls the entire device. The controller's working principle is existing technology and will not be elaborated here. When performing strength testing on bridge structural components, the bridge structural components are placed on a placement plate 3 located below the pressure block 5. The controller activates the first electric telescopic rod 4. The output shaft of the first electric telescopic rod 4 drives the pressure block 5 downwards, applying pressure to the bridge structural components on the placement plate 3. This is achieved through a Siemens SIMATIC S7-1500 controller. The P3AP pressure sensor 501 can monitor the pressure applied to bridge structural components. By observing the deformation and breakage of bridge structural components under different pressures, the strength of the bridge structural components can be tested. When testing the strength of irregularly shaped bridge structural components, a shaping mechanism first shapes the components, eliminating the need for manual shaping and reducing the workload for staff. After shaping, the regularly shaped component is placed on the placement plate 3 below the pressure block 5. Similarly, the controller activates the first electric telescopic rod 4, which moves the pressure block 5 downwards to press down on the shaped component and apply pressure for strength testing. At this time, the pressure block 5 can evenly transfer the applied load to the shaped component, thereby improving the accuracy of the strength test of the bridge structural components. Through this entire device, the strength of bridge structural components can be tested, and irregularly shaped bridge structural components can be shaped, allowing the pressure block 5 to evenly transfer the applied load to the bridge structural components, thus improving the accuracy of the strength test.

[0022] In a further preferred embodiment of the present invention, the trimming mechanism includes a drilling mechanism and a grinding mechanism. The drilling mechanism is used to drill and sample bridge structural components, and the grinding mechanism is used to grind the ends of the drilled samples. The drilling mechanism includes: a second electric telescopic rod 6 fixedly installed on the mounting frame 1, and a placement frame 7 fixedly installed on the output shaft of the second electric telescopic rod 6; a first servo motor 8 fixedly installed on the placement frame 7, and a drill cylinder 9 fixedly installed on the output shaft of the first servo motor 8. The drill cylinder 9 is used to drill samples of the bridge structural components placed on the placement plate 3, and the drill cylinder 9 is located above one of the placement frames 2.

[0023] In this embodiment, the bridge structural component is shaped and modified. First, the irregularly shaped bridge structural component is fixed on the placement plate 3 located below the drill cylinder 9. The first servo motor 8 is started by the controller. The output shaft of the first servo motor 8 drives the drill cylinder 9 fixed on it to rotate. Then, the second electric telescopic rod 6 is started by the controller. The second electric telescopic rod 6 drives the rotating drill cylinder 9 to move down and contact the irregularly shaped bridge structural component placed on the placement plate 3. At this time, the rotating drill cylinder 9 can drill a sample from the bridge structural component placed on the placement plate 3. After sampling, the two ends of the sample are ground by the grinding mechanism so that the drilled sample is in the shape of a regular cylinder. Then, the modified sample is placed on the placement plate 3 located below the pressure block 5. Similarly, the first electric telescopic rod 4 is started by the controller to drive the pressure block 5 to move down and press down on the modified part to apply pressure for strength testing. At this time, the pressure block 5 can evenly transfer the applied load to the modified part of the test piece, thereby improving the accuracy of the strength test of the bridge structural component.

[0024] In a further preferred embodiment of the present invention, the support seat 12 on the mounting frame 1 is used to place the drilled sample, and the grinding mechanism includes: a fourth electric telescopic rod 16 fixedly mounted on the mounting frame 1; a third servo motor 17 fixedly mounted on the output shaft of the fourth electric telescopic rod 16, a placement shaft 18 connected to the output shaft of the third servo motor 17 via a coupling, and a grinding block 19 fixedly mounted on the placement shaft 18, the grinding block 19 being used to grind the end of the drilled sample placed on the support seat 12.

[0025] In this embodiment, after the sample is drilled, the drilled sample is fixed on the support base 12. Then, the third servo motor 17 is started by the controller. The third servo motor 17 drives the placement shaft 18 and the grinding block 19 to rotate. Then, the fourth electric telescopic rod 16 is started by the controller. The fourth electric telescopic rod 16 drives the rotating grinding block 19 to approach the end of the sample, thereby grinding the end of the drilled sample placed on the support base 12.

[0026] In a further preferred embodiment of the present invention, a second servo motor 10 is fixedly mounted on the mounting frame 1. The output shaft of the second servo motor 10 is connected to a mounting shaft 11 via a coupling. The top end of the mounting shaft 11 is fixedly connected to the bottom of the support base 12. A positioning mechanism is provided on the support base 12. The positioning mechanism is used to position the drilled sample on the support base 12.

[0027] In this embodiment, after grinding one end of the drilled sample, the controller starts the second servo motor 10. The output shaft of the second servo motor 10 drives the mounting shaft 11 to rotate 180 degrees, which in turn drives the support base 12 to rotate, adjusting the other end of the drilled sample fixed on the support base 12 to one side of the grinding block 19. Similarly, the controller starts the third servo motor 17, which drives the placement shaft 18 and the grinding block 19 to rotate. Then, the controller starts the fourth electric telescopic rod 16, which drives the rotating grinding block 19 to approach the other end of the sample for grinding, thus facilitating comprehensive grinding of the sample end from different directions.

[0028] In a further preferred embodiment of the present invention, the positioning mechanism includes: a bracket 13 fixedly installed on the support base 12; a third electric telescopic rod 14 fixedly installed on the bracket 13, and a positioning ring 15 fixedly installed on the output shaft of the third electric telescopic rod 14, the positioning ring 15 being used to squeeze and position the drilled sample placed on the support base 12.

[0029] In this embodiment, the drilled sample is fixed on the support base 12. The third electric telescopic rod 14 is activated by the controller. The third electric telescopic rod 14 pushes the positioning ring 15 to move towards the sample until the positioning ring 15 tightly squeezes the sample, firmly positioning the sample on the support base 12, which facilitates the grinding operation of the sample.

[0030] In a further preferred embodiment of the present invention, a cooling mechanism is provided on the mounting frame 1. The cooling mechanism is used to cool the drill barrel 9. The cooling mechanism includes: a water tank 20 disposed on the mounting frame 1; a water pump 21 fixedly installed on the water tank 20, with an inlet pipe 22 connected to the inlet end of the water pump 21, the inlet pipe 22 extending into the water tank 20; a bent pipe 23 fixedly installed on the mounting frame 1, the bent pipe 23 communicating with the outlet end of the water pump 21; and a connecting pipe 24 fixedly installed on the inner wall of one of the placement frames 2, the connecting pipe 24 communicating with the bent pipe 23, and the connecting pipe 24 having multiple spray nozzles 25.

[0031] In this embodiment, during actual use, when the drill barrel 9 on the drilling mechanism drills samples of the bridge structural components placed on the placement plate 3, the control valve on the bend 23 is opened, and the water pump 21 is started by the controller. The water pump 21 sprays the cooling water in the water tank 20 through the inlet pipe 22, its own outlet, the bend 23, the connecting pipe 24, and finally from the spray nozzle 25 onto the drill barrel 9 to cool down the drill barrel 9, reduce wear on the drill barrel 9, extend its service life, and ensure the quality of the drilled samples.

[0032] In a further preferred embodiment of the present invention, a horizontal pipe 26 is connected to the bent pipe 23, a flexible hose 27 is connected to the horizontal pipe 26, a nozzle is provided on the flexible hose 27, the nozzle is located on one side of the grinding block 19, and a control valve is provided on both the horizontal pipe 26 and the bent pipe 23.

[0033] In this embodiment, control valves are provided on both the horizontal pipe 26 and the bend pipe 23. The control valves can precisely control the flow rate and direction of the cooling water. When only cooling of the drill barrel 9 is required, the control valve on the horizontal pipe 26 can be closed, allowing all the cooling water to be sprayed onto the drill barrel 9 through the bend pipe 23 and the connecting pipe 24. When the sample end is being polished on the polishing block 19, in order to avoid the high temperature generated by polishing affecting the polishing effect and sample quality, the control valve on the horizontal pipe 26 can be opened, while the control valve on the bend pipe 23 can be closed, and the water pump 21 can be started. The water pump 21 will pump the cooling water in the water tank 20 through the inlet pipe 22, its own outlet, the bend pipe 23, the horizontal pipe 26, and the hose 27 in sequence, and finally spray it onto the polishing block 19 through the nozzle on the hose 27, thereby cooling the polishing block 19 and reducing the damage caused by the high temperature to the polishing block 19. The operation can be adjusted according to actual needs, making it quite flexible.

[0034] In a further preferred embodiment of the present invention, the placement frame 2 is provided with a plurality of fixing mechanisms, which are used to fix the bridge structural components within the placement frame 2. The fixing mechanism includes: a screw 28 threadedly mounted on the placement frame 2; and a fixing block 29 fixedly mounted on the screw 28. The fixing block 29 is used to position the bridge structural components by contact, and a friction pad is provided on the fixing block 29.

[0035] In this embodiment, after the bridge structural component is placed in the placement frame 2, the operator rotates the lead screw 28, which causes the fixing block 29 to move towards the bridge structural component until the friction pad on the fixing block 29 is tightly against the surface of the bridge structural component. Through the coordinated action of multiple fixing mechanisms, the bridge structural component is firmly fixed in the placement frame 2 from different directions, which facilitates the strength testing and sampling of the bridge structural component.

[0036] In a further preferred embodiment of the present invention, a connecting shaft 30 is rotatably mounted on the two placement frames 2, and the connecting shaft 30 is fixedly connected to the two placement plates 3. A worm gear 31 is fixedly sleeved on the connecting shaft 30. A worm 32 is rotatably mounted on the outer wall of the placement frame 2 via a damping shaft. The worm 32 and the worm gear 31 mesh with each other. A limit block 33 is fixedly mounted on the inner wall of the placement frame 2, and the limit block 33 contacts the bottom of the placement plate 3. A recycling tank 34 is provided inside the mounting frame 1, and the recycling tank 34 is used to collect the used cooling water. The recycling bin 34 is equipped with a filter screen 35 for filtering impurities in the recycled water. A positioning rod 37 is fixedly installed at the bottom of the filter screen 35. A support plate 36 is fixedly installed on the inner wall of the recycling bin 34. The positioning rod 37 and the positioning hole on the support plate 36 are adapted to each other. Guide frames 38 are fixedly installed on both the pressure block 5 and the placement frame 7. A guide rod 39 is fixedly installed on the inner wall of the mounting frame 1. The guide rod 39 and the guide frame 38 are slidably connected. A transparent protective door is hinged on the mounting frame 1.

[0037] In this embodiment, during actual use, after performing hard stress testing or sampling on the bridge structural components placed on the placement plate 3, the staff removes large pieces of debris. When it is necessary to clean some small debris, the staff rotates the worm gear 32. Since the worm gear 32 and the worm wheel 31 mesh with each other, the rotation of the worm gear 32 will drive the worm wheel 31 to rotate, which in turn drives the connecting shaft 30 to rotate. Finally, the placement plate 3, which is fixedly connected to the connecting shaft 30, rotates and flips, thus facilitating the cleaning of residual debris on the placement plate 3. After cleaning, the worm gear 32 is rotated in the opposite direction to reset the placement plate 3. During the cooling process, the cooling water will carry debris generated during sample drilling, powder generated during sample grinding, and other impurities into the recovery box 34. At the same time, the impurities can be intercepted by the filter screen 35. A positioning rod 37 is fixedly installed at the bottom of the filter screen 35, and a support plate 36 is fixedly installed on the inner wall of the recovery box 34. The filter screen 35 can be stably installed in the recovery box by the matching connection between the positioning rod 37 and the positioning hole on the support plate 36. Inside the collection box 34, during the flow and filtration of recycled water, the filter screen 35 will not shift or shake due to the impact of water flow, ensuring the stability of the filtration effect. At the same time, after the filter screen 35 has been used for a period of time, a lot of impurities will accumulate on it, affecting the filtration efficiency. At this time, the staff can easily and quickly take out the filter screen 35 from the collection box 34 for cleaning or replacement through the matching connection between the positioning rod 37 and the positioning hole. The operation is convenient and simple. When the first electric telescopic rod 4 drives the pressure block 5 to move downward to apply pressure, or the second electric telescopic rod 6 drives the placement frame 7 to move up and down, due to the sliding connection between the guide frame 38 and the guide rod 39, the guide rod 39 can provide precise guidance for the movement of the guide frame 38. This makes the pressure block 5 and the placement frame 7 only move in a straight line along the direction of the guide rod 39, effectively avoiding their deviation or shaking during the movement. Through the transparent protective door, the flying debris and powder generated during the drilling, grinding, and strength testing of bridge structural components can be intercepted, improving the safety of the operation.

[0038] This invention also proposes a method for testing the strength of structural components, comprising: S1: When performing strength testing on regular structural components, the regular structural components are placed on the placement plate 3 located below the pressure block 5. The first electric telescopic rod 4 is activated by the controller. The output shaft of the first electric telescopic rod 4 drives the pressure block 5 to move down and apply pressure to the bridge structural components on the placement plate 3. The strength of the bridge structural components is tested by observing the deformation and breakage of the bridge structural components under different pressures. S2: When conducting strength tests on irregularly shaped bridge structural components, the components are first shaped using a shaping mechanism. After shaping, the shaped component is placed on the placement plate 3 located below the pressure block 5. Similarly, the controller activates the first electric telescopic rod 4 to move the pressure block 5 downwards, pressing down on the shaped component and applying pressure for strength testing. At this time, the pressure block 5 can evenly transfer the applied load to the shaped component. In summary, compared with related technologies, when performing strength testing on bridge structural components, the bridge structural component is placed on the placement plate 3 located below the pressure block 5. The first electric telescopic rod 4 is activated by the controller. The output shaft of the first electric telescopic rod 4 drives the pressure block 5 to move downwards, applying pressure to the bridge structural component on the placement plate 3. This is achieved using an HBM-type... The P3AP pressure sensor 501 can monitor the pressure applied to bridge structural components. By observing the deformation and breakage of bridge structural components under different pressures, the strength of the bridge structural components can be tested. When testing the strength of irregularly shaped bridge structural components, a shaping mechanism is first used to shape the components, eliminating the need for manual shaping and reducing the workload of staff. After shaping, the regularly shaped component is placed on the placement plate 3 below the pressure block 5. Similarly, the controller activates the first electric telescopic rod 4, which moves the pressure block 5 downwards to press down on the shaped component and apply pressure for strength testing. At this time, the pressure block 5 can evenly transfer the applied load to the shaped component, thereby improving the accuracy of the strength test of the bridge structural components. This device can perform strength testing on bridge structural components and shape shaping on irregular bridge structural components, allowing the pressure block 5 to evenly transfer the applied load to the bridge structural components, thus improving the accuracy of the strength test.
