Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of bridge bearing detection, and in particular relates to a road bridge bearing detection device. Background Art
[0002] The bridge bearing is an important structural component that connects the superstructure and substructure of the bridge. It can reliably transmit the reaction force and deformation (displacement and rotation angle) of the superstructure of the bridge to the substructure of the bridge, so that the actual stress of the structure is consistent with the calculated theoretical diagram. After the bridge bearing is processed, the detection of the bridge bearing has become one of the indispensable processing processes. By adopting advanced detection technology and strict detection standards, the problems of the bearing can be discovered and solved in time, thereby extending the service life of the bridge and ensuring traffic safety.
[0003] However, there are still some problems in the actual use of the existing road bridge bearing detection device: first, in the existing bridge bearing detection process, the bridge bearing is usually pressurized by a hydraulic rod, so that the bearing capacity of the bridge bearing can be detected. However, when the bearing capacity of the top area of the bridge is detected by the hydraulic rod, the load on the bearing surface of the bridge bearing will be the same. In the working process of the bridge bearing, it will bear a variety of loads, including dead loads (such as the dead weight of the structure), live loads (such as dynamic loads of vehicles, pedestrians, etc.), loads caused by temperature changes, loads caused by concrete shrinkage creep, etc. If only the same load is applied to the top surface of the bridge bearing during the detection, it will cause inaccurate detection of the structure, which may lead to failure to timely discover potential safety hazards, thereby increasing the safety risk of the bridge structure; secondly, during the detection process, it is necessary to ensure that the bearing is accurately installed in the center position to ensure the accuracy of the test results. When the bearing is accurately installed in the center position of the detection device, it can ensure that the load applied to the bearing is evenly distributed, avoiding measurement errors caused by eccentric loads. The accurate installation position helps to simulate the stress state of the bridge support in actual use, so as to more accurately evaluate the performance and safety of the bearing.

A plurality of sliding grooves are provided, and a plurality of pressure rods 14 are slidably connected inside the plurality of sliding grooves. Two fixed plates 15 are fixedly connected to both sides of the top of the plurality of pressure rods 14, respectively. A pressure plate 16 is fixedly connected to the bottom of the pressure rod 14. A positioning component is provided inside the detection table 1. By starting the first drive motor 6, the first drive motor 6 rotates to drive the first rotating shaft 7 to rotate, and the first rotating shaft 7 rotates to drive the plurality of eccentric wheels 11 to rotate. When the eccentric wheel 11 rotates, due to the eccentric design of the eccentric wheel 11, an up and down displacement will be generated when the eccentric wheel 11 rotates. After the eccentric wheel 11 moves up and down, it can drive the fixed plate 15 to move up and down. The up and down movement of the fixed plate 15 drives the pressure rod 14 and the pressure plate 16 to move up and down, thereby being able to well simulate the variable load that the first bridge bearing 28 needs to bear during operation, which is conducive to improving the accuracy of the detection results, and being able to more timely discover potential safety hazards, thereby reducing the safety risks of the bridge structure and improving the detection effect.
[0021] Wherein, the positioning component includes a plurality of connecting columns 17, and the plurality of connecting columns 17 are fixedly connected to the bottom of the detection table 1 around the periphery, the bottom of the connecting column 17 is fixedly connected to a second support plate 18, the middle of the top of the second support plate 18 is fixedly connected to a second drive motor 19, the output end of the second drive motor 19 is fixedly connected to a third rotating shaft 20, the top of the detection table 1 is fixedly connected to a placement base plate 21, the top of the third rotating shaft 20 is fixedly connected to a rotating disk 22, the rotating disk 22 is slidably connected to the inside of the placement base plate 21, and a plurality of arc guide grooves 27 are provided inside the rotating disk 22, the positioning component also includes a plurality of fixed blocks 23, the plurality of fixed blocks 23 are fixedly connected to the top of the placement base plate 21 around the periphery, the tops of the plurality of fixed blocks 23 are respectively slidably connected to a plurality of sliders 24, one side of the plurality of sliders 24 are fixedly connected to a centripetal positioning claw 25, the bottom of one end of the slider 24 is fixedly connected to a sliding column 26, the plurality of sliding columns 26 are respectively slidably connected to the inside of the plurality of arc guide grooves 27, the top of the rotating disk 22 is placed A first bridge support 28 is provided. By starting the second drive motor 19, the second drive motor 19 starts to drive the third rotating shaft 20 to rotate. The rotation of the third rotating shaft 20 drives the rotating disk 22. The rotation of the rotating disk 22 drives multiple arc guide grooves 27 inside it to rotate with it. After the position of the arc guide groove 27 moves, since the fixed block 23 is fixedly connected to the top of the placement base plate 21, the displacement of the fixed block 23 will drive the sliding column 26 to move along the arc guide groove 27. At this time, the slider 24 will slide on the surface of the slider 24, so that the rotation of the rotating disk 22 drives the movement of multiple sliders 24 and the centripetal positioning claw 25, thereby centripetally positioning the first bridge support 28, thereby ensuring the accuracy of the test results. When the support is accurately installed at the center position of the detection device, it can ensure that the load applied to the support is evenly distributed, avoiding measurement errors caused by eccentric loads. At the same time, the accurate installation position helps to simulate the stress state of the bridge support in actual use, thereby more accurately evaluating the performance and safety of the support.
[0022] Among them, the curvature of the circular arc surface of the centripetal positioning claw 25 is the same as the curvature of the circular arc of the first bridge support 28, and the centripetal positioning claw 25 is fitted with the outer side surface of the first bridge support 28, so that the curvature of the circular arc of the centripetal positioning claw 25 is the same as that of the first bridge support 28. In order to enable the centripetal positioning claw 25 to better fit its outer surface during centripetal positioning, the positioning area is increased, so that the centripetal positioning effect is better.
[0023] Among them, two limit blocks 29 are fixedly connected to the inner sides of the bottom of the multiple sliders 24, and two slide grooves are opened at the bottom of the fixed block 23. The width and height of the limit blocks 29 are the same as those of the slide grooves. The width and height of the limit blocks 29 are made the same as those of the slide grooves. In order to make the limit blocks 29 fit better with the slide grooves, their sliding stability is improved.
[0024] The top surface height of the rotating disk 22 is the same as that of the bottom plate 21, and there is a gap between the fixed block 23 and the surface of the rotating disk 22, and there is a gap of 1 mm between the fixed block 23 and the rotating disk 22 to avoid a large amount of friction during the rotation process, thereby affecting the service life of the workpiece.
[0025] Among them, the diameter of the sliding column 26 is the same as the diameter of the arc-shaped guide groove 27, the curvature of the two sides of the arc-shaped guide groove 27 is the same as the arc curvature of the sliding column 26, the length of the sliding column 26 is flush with the bottom surface of the rotating disk 22, the contact surface between the fixed plate 15 and the limiting groove 12 is an arc surface and the curvature of the arc surface is the same as the curvature of the limiting groove 12, the limiting groove 12 is a standard circular groove, and the contact surface between the fixed plate 15 and the limiting groove 12 is set to an arc surface, so that the eccentric wheel 11 can rotate more smoothly, and no reaction force will be generated due to the setting and friction of the fixed plate 15, thereby improving the service life of the workpiece, the limiting groove 12 is a standard circular groove, which means that the limiting groove 12 and the eccentric wheel 11 are concentric circles, and the diameter of the limiting groove 12 is smaller than the eccentric wheel 11.
[0026] Among them, multiple eccentric wheels 11 are arranged in a wave shape, the length of multiple fixed plates 15 is shorter than the width of the limiting groove 12, the sliding groove at the bottom of the limiting bottom plate 13 penetrates the installation box 3, the pressure rod 14 is slidably connected to the installation box 3, the pressure rod 14 and the sliding groove are both rectangular structures, and the eccentric wheel 11 is wavy. After the first drive motor 6 rotates, the first bridge bearing 28 can bear different top surface loads, thereby simulating the load borne by the first bridge bearing 28 in the actual working process, thereby improving the accuracy of detection.
[0027] Working principle: During the working process, after the first bridge support 28 is placed on the surface of the placement base plate 21, the second drive motor 19 is started, and the second drive motor 19 is started to drive the third rotating shaft 20 to rotate. The rotation of the third rotating shaft 20 drives the rotating disc 22, and the rotation of the rotating disc 22 drives the multiple arc guide grooves 27 inside it to follow its rotation. After the position of the arc guide groove 27 moves, since the fixed block 23 is fixedly connected to the top of the placement base plate 21, the displacement of the fixed block 23 will drive the sliding column 26 to move along the arc guide groove 27. At this time, the slider 24 will slide on the surface of the slider 24, so that the rotation of the rotating disc 22 drives the movement of multiple sliders 24 and the centripetal positioning claw 25, thereby centripetally positioning the first bridge support 28 to ensure the accuracy of the test results. When the support is accurately installed at the center position of the detection device, it can ensure that the subsequent load applied to the support is evenly distributed, avoiding measurement errors caused by eccentric loads. The accurate installation position helps to simulate the stress state of the bridge support in actual use, thereby more accurately evaluating the performance and safety of the support; After the first bridge support 28 is positioned, the first drive motor 6 is started. The rotation of the first drive motor 6 drives the first rotating shaft 7 to rotate. The rotation of the first rotating shaft 7 drives the first gear 8 to rotate. The rotation of the first gear 8 drives the second gear 9 to rotate. The rotation of the second gear 9 drives the second rotating shaft 10 to rotate. The rotation of the second rotating shaft 10 drives multiple eccentric wheels 11 to rotate. When the eccentric wheel 11 rotates, due to the eccentric design of the eccentric wheel 11, an up and down displacement will be generated when the eccentric wheel 11 rotates. After the up and down displacement of the eccentric wheel 11, it can drive the fixed plate 15 to move up and down. The up and down movement of the fixed plate 15 drives the pressure rod 14 and the pressure plate 16 to move up and down, thereby simulating the variable load that the first bridge support 28 needs to bear when working, which is conducive to improving the accuracy of the detection results. At the same time, it can more timely discover potential safety hazards, thereby reducing the safety risks of the bridge structure and improving the detection effect.
[0028] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
