Description

Technical Field

[0001] This utility model relates to the field of road and bridge technology, and specifically to a road and bridge bearing detection device. Background Technology

[0002] Bridge bearings are critical load-bearing components of bridge structures, one of their core functions being to reliably transfer the loads of the superstructure to the piers or abutments. Therefore, the compressive strength of the bearings and their stability under long-term loads are important indicators for assessing bridge safety and service life. If bearings experience decreased compressive strength, excessive compression, or plastic deformation due to quality defects, aging, or fatigue, it will directly alter the stress state of the bridge, leading to stress redistribution in the beam and potentially causing a series of serious consequences such as pavement damage and structural cracking, threatening the operational safety of the bridge.

[0003] When testing the compressive performance of bearings (such as compressive stiffness testing, ultimate bearing capacity testing, or long-term creep performance testing), the bearing sample must first be stably and reliably clamped between the upper and lower pressure plates of the loading testing machine. Currently, the clamping and loading methods commonly used in laboratories or in the field have the following significant problems: difficulty in clamping and centering, easily introducing eccentric pressure, leading to inaccurate test data; insufficient clamping stability, the bearing may slip under high pressure, posing a safety hazard; poor adaptability, unable to be quickly adjusted to meet the testing requirements of different bearing specifications.

[0028] like Figure 1-5 As shown, this utility model has the following three specific embodiments.

[0029] Example 1

[0030] A road and bridge bearing detection device includes a base 1, with support frames 2 fixedly connected to the left and right sides of the upper end of the base 1, and an mounting frame 8 fixedly connected to the upper end of the support frame 2. Centering components 3 are provided on the front and rear sides of the upper end of the base 1. First hydraulic cylinders 4 are fixedly connected to the left and right sides of the support frame 2. The output end of the first hydraulic cylinder 4 passes through the support frame 2 and is fixedly connected to a clamping plate 5. A detection component 11 is provided inside the mounting frame 8, and an operation panel 12 is fixedly connected to one end of the front side of the support frame 2.

[0031] The first adjustment component is located in the middle of the base 1 and is used to adjust the spacing between the centering components 3;

[0032] The second adjustment component is located inside the mounting bracket 8 and is used to adjust the position of the detection component 11.

[0033] A cleaning component is located on one side of the support frame 2 and is used to clean dust.

[0034] In this embodiment, as Figures 1-5 As shown, the overall structure of the road and bridge bearing testing device is provided. The base 1 serves as the basic support, the support frame 2 and the mounting frame 8 constitute the main frame, the centering component 3 is used to place and guide the bearing, the first hydraulic cylinder 4 and the clamping plate 5 are used to clamp and fix the bearing, the testing component 11 performs pressure testing through the mounting frame 8, the operation panel 12 integrates control functions, the first adjustment component can adjust the spacing of the centering component 3, the second adjustment component can move the testing component 11, and the cleaning component is used to maintain the testing environment.

[0035] Example 2

[0036] The difference from Embodiment 1 is that this embodiment discloses centering component 3 and a first adjustment component:

[0037] The centering component 3 includes a connecting frame 24, with several rollers 26 rotatably connected inside the connecting frame 24, and a slider 25 fixedly connected to the middle position of the bottom end of the connecting frame 24;

[0038] The first adjustment component includes a slide 13, which is located in the middle of the base 1. A bidirectional screw 14 is rotatably connected inside the slide 13. A second servo motor 15 is fixedly connected to the middle of the rear side of the base 1. The output end of the second servo motor 15 is fixedly connected to one end of the bidirectional screw 14.

[0039] The slider 25 is slidably connected to the groove 13, and the slider 25 is threadedly connected to one side of the corresponding bidirectional screw 14.

[0040] In this embodiment, as Figures 1-5As shown, the centering component 3 facilitates the placement and movement of the support through the roller 26, and the slider 25 cooperates with the slide groove 13 to achieve sliding. The first adjustment component drives the bidirectional screw 14 to rotate through the second servo motor 15, which drives the slider 25 to move along the slide groove 13, thereby adjusting the distance between the two centering components 3, so that the support can be automatically centered and adapt to different width specifications.

[0041] Example 3

[0042] The difference from Embodiment 1 is that this embodiment discloses a detection component 11, a second adjustment component, and a cleaning component:

[0043] The detection component 11 includes a connecting block 19. A second hydraulic cylinder 20 is fixedly connected to the middle position of the upper end of the connecting block 19. A connecting plate 21 is fixedly connected to the output end of the second hydraulic cylinder 20 through the connecting block 19. A pressure sensor 22 is fixedly connected to the bottom end of the connecting plate 21. A pressing plate 23 is fixedly connected to the bottom end of the pressure sensor 22.

[0044] The second adjustment component includes a first screw 9 located on the front and rear sides. The first screw 9 is rotatably connected to the mounting frame 8. A sprocket 17 is fixedly connected to one end of each first screw 9. The sprockets 17 are driven by a chain 18. A first servo motor 10 is fixedly connected to one side of the mounting frame 8. The output end of the first servo motor 10 is fixedly connected to one end of the corresponding first screw 9. The two sides of the connecting block 19 are threadedly connected to the corresponding first screw 9.

[0045] The cleaning component includes a fan 6, which is fixedly connected to one end of the support frame 2. The output end of the fan 6 is fixedly connected to an air outlet pipe 7 through the support frame 2, and a protective net 16 is fixedly connected to the output end of the fan 6.

[0046] In this embodiment, as Figures 1-5 As shown, the detection component 11 drives the connecting plate 21 and the extrusion plate 23 to apply pressure to the support through the second hydraulic cylinder 20. The pressure sensor 22 monitors the pressure value in real time. The second adjustment component drives the sprocket 17 and the chain 18 through the first servo motor 10, so that the first screw 9 rotates synchronously, driving the connecting block 19 to move horizontally and adjust the detection position. The cleaning component blows away the dust through the fan 6 and the air outlet pipe 7. The protective net 16 prevents foreign objects from entering.

[0047] The working principle of this utility model is as follows:

[0048] First, place the support on the centering component 3 on the base 1. The roller 26 facilitates the movement and centering of the support. Start the second servo motor 15 through the operation panel 12 to drive the bidirectional screw 14 to rotate, so that the slider 25 moves along the slide groove 13, adjust the spacing of the centering component 3, and ensure that the support is in the center position.

[0049] Subsequently, the first hydraulic cylinder 4 is activated, pushing the clamping plate 5 to hold both sides of the support, fixing the support to prevent movement;

[0050] Then, the first servo motor 10 is started, and the first screw 9 is rotated synchronously through the sprocket 17 and the chain 18, so that the connecting block 19 drives the detection component 11 to move to a predetermined position above the support. The second hydraulic cylinder 20 is started, pushing the connecting plate 21 to move downward. The pressure sensor 22 and the extrusion plate 23 contact the support and apply pressure. The pressure sensor 22 monitors the pressure data in real time and records and analyzes it through the operation panel 12.

[0051] During the testing process, if dust removal is required, start the fan 6. The airflow will blow through the exhaust pipe 7 to the testing area to remove dust. The protective net 16 prevents debris from being sucked in. After the test is completed, reset all components and remove the support.

[0052] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. The selection and detailed description of these embodiments in this specification are intended to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it.
