Description

Technical Field

[0001] This utility model relates to the field of bridge engineering technology, and more specifically, it relates to a load-bearing capacity testing device for bridge engineering supervision. Background Technology

[0002] In the construction, operation and maintenance of bridges, the load-bearing capacity of a bridge is a core indicator for assessing its structural safety and durability. After the bridge is completed, the supervision department will conduct corresponding tests on the bridge samples according to the actual situation to calculate the load-bearing capacity of the entire bridge. When testing the bridge samples, testing equipment is required.

A C-shaped plate 3 is mounted on the output end of the press 2. Rollers 4 are rotatably mounted on the inner wall of the C-shaped plate 3 at the upper end. Multiple rollers 4 are evenly distributed. Sliding holes 5 are opened on both sides of the housing 1. Sliding blocks 6 are slidably mounted inside the sliding holes 5. A guide rod 7 is fixedly mounted in the middle of two sliding blocks 6. A moving block 8 is slidably mounted on the guide rod 7. The upper end of the moving block 8 contacts the roller 4. A mounting frame 9 is mounted on the lower end of the moving block 8. A pressure roller 10 is rotatably mounted inside the mounting frame 9. A lead screw 11 is rotatably mounted in the middle of the sliding block 6. The lead screw 11 is threadedly connected to the moving block 8. A first motor 12 is mounted on one end of the lead screw 11 at the outer wall of the sliding block 6. A receiving device is mounted on the inner wall of the housing 1 at the lower end. The two sides of the moving block 8 contact the inner wall of the C-shaped plate 3.

[0031] In this embodiment, the receiving device includes an adjustment hole 13. Two sets of adjustment holes 13 are provided and are both opened at the bottom of the housing 1. An adjustment block 14 is slidably provided inside the adjustment hole 13. A pad 15 is fixedly provided on the upper end surface of the adjustment block 14. A threaded rod is rotatably provided inside the adjustment hole 13. The threaded rod is threadedly connected to the adjustment block 14. A second motor 16 is fixedly provided at one end of the threaded rod and on the outer wall of the housing 1.

[0032] More specifically, the user can place the bridge sample on the top of the pad 15, and then input a pressure value through an external control device to control the press 2 to move the C-shaped plate 3 downwards, thereby applying downward pressure to the moving block 8 until the pressure roller 10 contacts the bridge sample, thus achieving the detection effect. This is convenient to use. During the detection, the first motor 12 can also be controlled to move the lead screw 11 to move the moving block 8 and the pressure roller 10, so that the pressure roller 10 rolls on the top of the bridge sample, thereby simulating dynamic pressure values ​​and improving the detection effect. When the bridge sample is small, the second motor 16 can be controlled to rotate the threaded rod, so that it drives the two adjusting blocks 14 and the pad 15 to move closer to each other, which helps to place bridge samples of different sizes and facilitates subsequent detection.

[0033] Please see Figure 1 , Figure 2 and Figure 5 As an embodiment for protecting the front end of the housing 1: a strip-shaped hole 17 is provided on the upper end face of the housing 1, and a protective plate 18 is slidably provided inside the strip-shaped hole 17. A threaded hole 19 is provided at the front end of the housing 1, and the threaded hole 19 communicates with the strip-shaped hole 17. A locking screw 20 is provided inside the threaded hole 19. A connecting hole 21 is provided on the outer wall of the protective plate 18 at the bottom. One end of the locking screw 20 is located inside the connecting hole 21. A sliding rod 22 is provided on the upper end face of the C-shaped plate 3 at both sides. The sliding rod 22 is slidably installed with the housing 1.

[0034] Specifically, during testing, the user can unscrew the locking screw 20 to open the connection hole 21, at which point the protective plate 18 can be lowered to cover the front end of the housing 1, thereby increasing the safety of the device.

[0035] Please refer to Figure 1 As a further embodiment for supporting the sliding block 6: each of the sliding blocks 6 is provided with a connecting spring 23 at its bottom, and the other end of each connecting spring 23 is fixedly connected to the inner wall of the sliding hole 5.

[0036] Specifically, the connecting spring 23 can support the sliding block 6 so that when the C-shaped plate 3 leaves the moving block 8, the pressure roller 10 can leave the bridge sample for easy inspection.

[0037] In summary, when using the entire equipment: the user can place the bridge sample on the top of the pad 15, and then input a pressure value through an external control device to control the press 2 to move the C-shaped plate 3 downwards, thereby applying downward pressure to the moving block 8 until the pressure roller 10 contacts the bridge sample. During testing, the first motor 12 can also be controlled to move the lead screw 11, causing the moving block 8 and pressure roller 10 to move, so that the pressure roller 10 rolls on the top of the bridge sample, simulating dynamic pressure values ​​for better testing results. After testing, the press 2 is controlled to raise the C-shaped plate 3, at which point the connecting spring 23 will push the sliding block 6... The sample is supported so that the pressure roller 10 is detached from the bridge sample. At this point, the integrity of the bridge sample can be checked to determine whether it can withstand the pressure value, thus achieving the testing effect. When the bridge sample is small, the threaded rod can be rotated by controlling the second motor 16 to drive the two adjusting blocks 14 and the pad 15 closer together, which helps to place bridge samples of different sizes and facilitates subsequent testing. Moreover, during testing, the user can also unscrew the locking screw 20 to unscrew the connecting hole 21, at which point the protective plate 18 can be lowered to cover the front end of the housing 1, thus increasing the safety of the device.

[0038] The motors mentioned above are all controlled by controllers or drivers.
