Technical Field
[0001] This utility model relates to the field of road and bridge inspection technology, and in particular to a vertical inspection device for roads and bridges. Background Technology
[0002] The safety of roads and bridges is of paramount importance, directly affecting the smooth flow of transportation and the safety of people's lives and property. With the increasing traffic volume and the aging of bridges, road and bridge structures may experience varying degrees of deformation due to various factors, such as long-term vehicle loads, natural environmental erosion, and changes in geological conditions. Among these factors, vertical deformation detection is one of the key aspects of assessing bridge safety performance.
[0003] In existing vertical inspection technologies for roads and bridges, common methods such as leveling can detect changes in bridge elevation to a certain extent, but the operation is cumbersome, requiring the establishment of leveling points at multiple locations on the bridge and multiple measurements and data conversions. Furthermore, it is greatly affected by environmental factors (such as terrain undulations and visibility conditions), resulting in low inspection efficiency and difficulty in quickly and intuitively obtaining the overall vertical deformation of the bridge. While total station measurement offers high accuracy, the equipment is expensive, the operation is complex, and it requires highly skilled operators. Moreover, the setup and debugging of the instrument face numerous inconveniences in complex field environments, limiting its widespread application in routine bridge inspections. To address this technical problem, this application proposes a vertical inspection device for roads and bridges. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a road and bridge vertical detection device. When the bridge tilts, the angle measuring plate deflects accordingly. While the weight remains vertical, its pointer can clearly indicate the deflection angle on the scale of the angle measuring plate. The protective box of the device can not only effectively protect the internal components, but its internal space can also accommodate the support rod.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] A vertical inspection device for roads and bridges includes a protective box. A rotating plate is rotatably connected to the top of the protective box. Fixed blocks are connected to both ends of the rotating plate via locking components. The fixed blocks are fixedly connected to the top of the protective box. An angle measuring plate is fixedly connected to the front end of the rotating plate. A rotating block is rotatably connected to the middle of the front end of the angle measuring plate. A connecting rod is fixedly connected to the bottom end of the rotating block. A weight is fixedly connected to the bottom end of the connecting rod. A pointer is fixedly connected to the bottom end of the weight. A sliding sleeve is rotatably connected to the rear end of the weight. A sliding rod is slidably connected to the inner wall of the sliding sleeve. The sliding rod is fixedly connected to the inner wall of the angle measuring plate. A locking block is fixedly connected to the rear end of the rotating plate. A locking plate is rotatably connected to the rear end of the locking block. A locking sleeve is fixedly connected to the front side of the top of the protective box. A door panel is rotatably connected to the bottom side of the rear end of the protective box. The door panel is connected to the rear end of the protective box via a limiting component.
[0007] Furthermore, the limiting component includes a sub-buckle located at the rear end of the door panel, and a female buckle is sleeved on the outer wall of the sub-buckle, which is fixedly connected to the rear end of the protective box.
[0008] Furthermore, the engaging assembly includes tenons located at the left and right ends of the rotating plate. Each of the two tenons is fixedly connected to a limiting plate at one end, and each of the two limiting plates is fixedly connected to a pull rod at one end. Both pull rods are slidably connected to the inner wall of the fixing block, and springs are provided on the outer walls of both pull rods.
[0009] Furthermore, one end of each of the two springs is connected to the inner wall of the fixed block, and the other end of each of the two springs is connected to the opposite ends of the two limiting plates.
[0010] Furthermore, a positioning block is fixedly connected to the bottom of the protective box, and a support rod is slidably connected to the outer wall of the positioning block.
[0011] Furthermore, a handle is fixedly connected to the front end of the protective box.
[0012] Furthermore, the front end of the angle measuring plate is provided with a scale.
[0013] This utility model has the following beneficial effects:
[0014] 1. In this utility model, when the bridge tilts, the angle measuring plate tilts accordingly. While the weight remains vertical, its pointer can clearly indicate the tilt angle on the scale of the angle measuring plate. The operator can directly read the scale value without complicated calculations or the use of other auxiliary tools, and can quickly and accurately obtain the tilt of the bridge, providing intuitive and reliable data for the inspection of road bridges.
[0015] 2. In this utility model, the protective box of the device can not only effectively protect the internal components, but its internal space can also accommodate the support rod. The door panel of the device is tightly connected to the protective box through male and female buckles. During transportation or storage, it can prevent the loss of components. The overall structure is compact, and the components cooperate with each other in the storage state. It occupies little space and is convenient to carry and store. It can be easily managed in different environments, whether in the laboratory or on the construction site, thus improving the practicality and mobility of the device. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Reference Figures 1-3This utility model provides an embodiment of a road and bridge vertical detection device, comprising a protective box 1, a rotating plate 5 rotatably connected to the top of the protective box 1, and fixing blocks 7 connected to both ends of the rotating plate 5 via tenons 10, limiting plates 9, and pull rods 8. The fixing blocks 7 are fixedly connected to the top of the protective box 1. An angle measuring plate 12 is fixedly connected to the front end of the rotating plate 5, and a rotating block 13 is rotatably connected to the middle of the front end of the angle measuring plate 12. A connecting rod 14 is fixedly connected to the bottom end of the rotating block 13, and a connecting rod 14 is fixedly connected to the bottom end of the connecting rod 14. A weight 15 is fixedly connected to a pointer 16 at its bottom end. A sliding sleeve 17 is rotatably connected to the rear end of the weight 15. A sliding rod 18 is slidably connected to the inner wall of the sliding sleeve 17. The sliding rod 18 is fixedly connected to the inner wall of the angle measuring plate 12. A locking block 2 is fixedly connected to the rear end of the rotating plate 5. A locking plate 3 is rotatably connected to the rear end of the locking block 2. A locking sleeve 4 is fixedly connected to the front top of the protective box 1. A door panel 22 is rotatably connected to the bottom rear end of the protective box 1. The door panel 22 is connected to the rear end of the protective box 1 through a male buckle 21 and a female buckle 20.
[0025] Specifically, the entire vertical detection device is placed on the bridge section to be inspected. At this time, the weight 15 remains vertical due to gravity. When the surface of the road bridge is uneven, the rotating plate 5 connected to the protective box 1 and the front measuring plate 12 will be tilted. During this process, the sliding sleeve 17 at the rear end of the weight 15 will slide on the sliding rod 18 on the inner wall of the measuring plate 12 to ensure that the weight 15 is vertical. The pointer 16 at the bottom of the weight 15 will indicate the angle of bridge tilt on the scale at the front end of the measuring plate 12. Rotate the locking plate 3 at the rear end of the locking block 2 to disengage it from the locking sleeve 4 at the front of the top of the protective box 1, release the lock on the rotating plate 5, and unfold the rotating plate 5 from the protective box 1.
[0026] Reference Figure 1 , Figure 4 and Figure 5 The door panel 22 has a male buckle 21 at the rear end, and a female buckle 20 is fitted on the outer wall of the male buckle 21. The female buckle 20 is fixedly connected to the rear end of the protective box 1. The tenons 10 at the left and right ends of the rotating plate 5 are fixedly connected to the limiting plate 9 at one end. The limiting plate 9 is fixedly connected to the pull rod 8 at one end. The pull rod 8 is slidably connected to the inner wall of the fixing block 7. The outer wall of the pull rod 8 is provided with a spring 11. One end of the spring 11 is connected to the inner wall of the fixing block 7. The other end of the spring 11 is connected to the two limiting plates 9 at one end. The bottom of the protective box 1 is fixedly connected to a positioning block 23. The outer wall of the positioning block 23 is slidably connected to a support rod 19. The front end of the protective box 1 is fixedly connected to a handle 6. The front end of the measuring plate 12 is provided with a scale.
[0027] Specifically, pulling the rod 8 on the inner wall of the fixing block 7 causes the limiting plate 9 to move, thereby disengaging the tenon 10 from its initial position and releasing the locking and fixing of the rotating plate 5. Conversely, releasing the rod 8 causes the limiting plate 9 to spring back under the elastic force of the spring 11, and the tenon 10 re-engages into the slot of the rotating plate 5, thus fixing the rotating plate 5. The male buckle 21 at the rear end of the door panel 22 is pulled out from the female buckle 20, thereby opening the door panel 22. The support rod 19 can be taken out from the protective box 1 or placed into the protective box 1. The support rod 19 can be installed through the positioning block 23. The vertical detection device can be moved to the appropriate position more conveniently through the handle 6.
[0028] Working principle: Move the vertical detection device to the road bridge to be inspected using handle 6. Open the door panel 22 using female buckle 20 and male buckle 21, take out the support rod 19, insert the support rod 19 into the positioning block 23, and fix the support rod 19 to the bottom of the protective box 1. Place the vertical detection device at the position to be inspected using the support rod 19. Then rotate the locking plate 3 on the locking block 2 to release the locking plate 3 from the locking sleeve 4. Pull the pull rod 8 to move the tenon 10 through the limiting plate 9. Then rotate the rotating plate 5 90 degrees to release the force applied to the pull rod 8. Under the action of the spring 11, the limiting plate 9 will spring back to its original position, so that the tenon 10 is locked into the slot of the rotating plate 5, thus fixing the rotating plate 5. Due to gravity, the weight 15 will always be vertical. When the road or bridge is uneven, the measuring plate 12 will tilt. Then, the sliding sleeve 17 on the weight 15 will slide on the sliding rod 18, so that the pointer 16 indicates the tilt angle on the measuring plate 12. After measuring the tilt angle of the road or bridge, pull the pull rod 8 to release the tenon 10 from the engagement with the rotating plate 5, rotate the rotating plate 5, and then rotate the clamping plate 3 into the slot of the clamping sleeve 4, so that the protective box 1 engages with the rotating plate 5. Then, the support rod 19 is removed from the positioning block 23 and placed into the protective box 1. The protective box 1 is engaged with the door panel 22 by the female buckle 20 and the male buckle 21. Then, the vertical detection device can be moved by the handle 6.
[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
