Description

Technical Field

[0001] This application relates to the field of road deflection detection technology, specifically a road deflection detection device. Background Technology

[0002] Deflection refers to the vertical deformation of a roadbed or pavement under a specified load. The amount of deflection caused by pavement rebound not only reflects the overall stiffness and strength of the roadbed and pavement structure, but also has a certain intrinsic relationship with the service condition of the pavement.

[0003] An existing patent (publication number: CN217026597U) discloses a municipal road curvature detection device, including a support frame and a box fixedly connected to the top of the support frame. The box contains detection components and a cleaning component. The device operates by activating a lifting rod, which in turn moves a sleeve up or down. The sleeve then moves a rod, thereby raising or lowering the curvature roller. This allows the roller to be pressed against the ground or retracted into the box, improving work efficiency. The roller pushes a limit plate, which in turn presses a pressure sensor via a spring, detecting the contact pressure between the roller and the ground. When the roller passes over a road surface with curvature deformation, the pressure sensor detects a change in pressure and sends an electrical signal to a warning light and alarm, alerting staff. This facilitates detection at different locations on the road surface, resulting in good detection performance.

[0004] However, in the above-mentioned solutions, it was found that in actual use, due to the large size of the overall device and the inability to fold the overall support frame, it is difficult to transport and store it in a limited space, resulting in poor portability. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a road deflection detection device that is foldable, easy to store and transport, and improves portability. It solves the problem that the overall support frame cannot be folded, making it difficult to transport and store in a limited space, resulting in poor portability.

[0006] To achieve the above objectives, this application provides the following technical solution: a road deflection detection device, comprising a mounting plate one and a mounting plate two. Two fixing members are fixedly mounted on the upper surface of the mounting plate one. A rotating member is rotatably connected to the outer surface of each fixing member. The bottom surface of each rotating member is fixedly connected to the upper surface of the mounting plate two. Two clamping members are fixedly connected to the upper surface of the mounting plate two. Two limiting blocks are fixedly connected to the upper surface of the mounting plate one. Two springs and two guide rods are fixedly connected to the left side of each limiting block. A locking block is provided on the left side of each limiting block. The inner wall of each locking block is slidably connected to the outer surface of the corresponding guide rod. The right side of each locking block is fixedly connected to the left end of the corresponding spring. A pressing member is fixedly connected to the left side of each locking block. A handle groove is provided on the upper surfaces of both the mounting plate one and the mounting plate two.

[0007] To improve the portability of the device, the above solution involves installing a fixing component and a rotating component on the upper surfaces of mounting plate one and mounting plate two. Connecting the fixing component and the rotating component allows mounting plate one and mounting plate two to be folded. When folded, the locking component contacts the inclined surface of the locking block through the circular surface of its surface, causing the locking block to slide on the surface of the guide rod. At this time, spring one is compressed. When the locking component is installed in place, the locking block is reset under the action of spring one, thus locking the locking component. Then, the opening of the carrying slot makes it easy to lift mounting plate one and mounting plate two, greatly improving the portability of the device.

[0008] Furthermore, the inner walls of both mounting plate one and mounting plate two are fixedly connected to fixed columns, and the bottom surfaces of both mounting plate one and mounting plate two are fixedly connected to two mounting columns. The inner wall of each mounting column is rotatably connected to a set of wheels.

[0009] The above scheme involves installing fixing columns on the inner walls of mounting plate one and mounting plate two to achieve the positioning and installation effect of the fixing columns. Additionally, mounting columns are installed on the bottom surfaces of mounting plate one and mounting plate two, and wheel sets are placed on the inner walls of the corresponding mounting columns, facilitating the movement of the entire device through the wheel sets.

[0010] Furthermore, a cylinder is provided on the right side of the mounting plate, and a limit plate is slidably connected to the inner wall of the cylinder.

[0011] The above scheme involves placing the cylinder on the right side of the mounting plate and installing the limiting plate on the inner wall of the cylinder, using a sliding connection to achieve the limiting effect of the limiting plate.

[0012] Furthermore, springs are fixedly connected to both the upper and lower surfaces of the limiting plate, and the ends of each spring that are far apart from each other are fixedly connected to the inner wall of the cylinder.

[0013] The above method fixes the second spring to the upper and lower surfaces of the limiting plate, and connects the other end of the second spring to the inner top and bottom walls of the cylinder to achieve the limiting effect of the limiting plate. The second spring allows the limiting plate to be pressed tightly, and when the limiting plate moves, it can be reset under the action of the second spring.

[0014] Furthermore, an installation rod is fixedly connected to the inner wall of the limiting plate, the outer surface of the installation rod is slidably connected to the inner wall of the cylinder, and a roller is fixedly connected to the bottom end of the installation rod.

[0015] The above scheme fixes the mounting rod to the inner wall of the limiting plate, setting it as a fixed connection to achieve the positioning and installation effect of the mounting rod. The cylinder is connected to the outer surface of the mounting rod, setting it as a fixed connection to achieve the limiting of the mounting rod. The roller component is installed at the bottom of the mounting rod, and the mounting rod can be raised and lowered by the lifting and lowering of the roller component.

[0016] Furthermore, a circular plate is fixedly connected to the top of the mounting rod, and two displacement sensors are fixedly installed on the bottom surface of the circular plate. The bottom end of each displacement sensor is fixedly connected to the upper surface of the cylinder.

[0017] The above scheme involves placing a circular plate at the top of the mounting rod and installing two displacement sensors on the bottom surface of the circular plate. The bottom ends of the displacement sensors are connected to the cylinder. The displacement sensors can detect the displacement of the circular plate, thereby detecting the displacement of the roller component. Furthermore, the contact between the roller component and the ground can be used to detect the road deflection.

[0018] Furthermore, a fixing ring is fixedly connected to the outer surface of the cylinder, and two connecting arms are fixedly connected to the outer surface of the fixing ring.

[0019] The above scheme involves installing the fixing ring on the surface of the cylinder as a fixed connection to achieve the positioning and installation effect of the fixing ring, and installing the connecting arm on the surface of the fixing ring as a fixed connection to achieve the positioning and installation effect of the connecting arm.

[0020] Furthermore, each of the connecting arms has a fixing bolt rotatably connected to its inner wall, and the outer surface of each fixing bolt is threadedly connected to the inner wall of the corresponding fixing post.

[0021] The above scheme involves installing the fixing bolts on the inner wall of the corresponding connecting arm and setting them as a rotating connection to limit the movement of the fixing bolts. The fixing bolts are then connected to the corresponding fixing columns, thereby fixing the cylinder below the first and second mounting plates. This ensures that the roller components are always in contact with the ground and allows the detection components to be disassembled and stored separately before the first and second mounting plates are folded.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This road deflection detection device, by setting up components such as a clamp, a clamping block, a spring, and a guide rod, allows mounting plates one and two to be folded through fixing and rotating parts. At this time, the surface of the clamp contacts the inclined surface of the clamping block, causing the clamping block to move on the surface of the guide rod and compress the spring. Then, under the action of the spring, the clamping block returns to its original position and locks the clamp. This allows the device to be easily folded, improving its portability and facilitating storage and transportation. By setting a fixing post on the inner wall of mounting plates one and two, the cylinder is connected to the groove between mounting plates one and two. Then, the connecting arm and the fixing post are connected by fixing bolts, achieving the effect of quick installation and disassembly of the detection components. Attached Figure Description

[0034] Please see Figure 2 , Figure 4 and Figure 5 A cylinder 14 is provided on the right side of the mounting plate 1. A limit plate 15 is slidably connected to the inner wall of the cylinder 14. The cylinder 14 is set on the right side of the mounting plate 1, and the limit plate 15 is installed on the inner wall of the cylinder 14. The connection is slidable to achieve the limiting effect of the limit plate 15.

[0035] Please see Figure 5 Springs 16 are fixedly connected to the upper and lower surfaces of the limiting plate 15. One end of each spring 16 is fixedly connected to the inner wall of the cylinder 14. The springs 16 are fixed to the upper and lower surfaces of the limiting plate 15, and the other end of the springs 16 is connected to the inner top and inner bottom walls of the cylinder 14 to achieve the limiting effect of the limiting plate 15. The limiting plate 15 can be pressed tightly by the springs 16, and when the limiting plate 15 moves, it can be reset under the action of the springs 16.

[0036] Please see Figure 2, Figure 3 and Figure 5 An installation rod 17 is fixedly connected to the inner wall of the limiting plate 15. The outer surface of the installation rod 17 is slidably connected to the inner wall of the cylinder 14. A roller component 18 is fixedly connected to the bottom end of the installation rod 17. The installation rod 17 is fixed to the inner wall of the limiting plate 15, which is a fixed connection to achieve the positioning and installation effect of the installation rod 17. The cylinder 14 is connected to the outer surface of the installation rod 17, which is a fixed connection to achieve the limiting of the installation rod 17. The roller component 18 is installed at the bottom end of the installation rod 17. The installation rod 17 can be raised and lowered by the raising and lowering of the roller component 18.

[0037] Please see Figure 5 A circular plate 19 is fixedly connected to the top of the mounting rod 17. Two displacement sensors 20 are fixedly installed on the bottom surface of the circular plate 19. The bottom end of each displacement sensor 20 is fixedly connected to the upper surface of the cylinder 14. The circular plate 19 is set at the top of the mounting rod 17, and two displacement sensors 20 are installed on the bottom surface of the circular plate 19. The bottom end of the displacement sensor 20 is connected to the cylinder 14. The displacement of the circular plate 19 can be detected by the displacement sensor 20, and then the displacement of the roller component 18 can be detected. In turn, the road deflection can be detected by the contact between the roller component 18 and the ground.

[0038] Please see Figure 2 and Figure 5 A fixing ring 21 is fixedly connected to the outer surface of the cylinder 14. Two connecting arms 22 are fixedly connected to the outer surface of the fixing ring 21. The fixing ring 21 is installed on the surface of the cylinder 14 to form a fixed connection, thereby achieving the positioning and installation effect of the fixing ring 21. The connecting arms 22 are installed on the surface of the fixing ring 21 to form a fixed connection, thereby achieving the positioning and installation effect of the connecting arms 22.

[0039] Please see Figure 5 Each connecting arm 22 has a fixing bolt 24 rotatably connected to its inner wall. The outer surface of each fixing bolt 24 is threaded to the inner wall of the corresponding fixing post 23. The fixing bolt 24 is installed on the inner wall of the corresponding connecting arm 22 and configured as a rotatable connection to limit the fixing bolt 24. The fixing bolt 24 is connected to the corresponding fixing post 23, thereby fixing the cylinder 14 below the mounting plate 1 and mounting plate 2, so that the roller component 18 can always be in contact with the ground. This allows the detection component to be disassembled and stored separately before mounting plate 1 and mounting plate 2 are folded.

[0040] This embodiment of a road deflection detection device includes components such as a clamp 5, a clamp block 7, a spring 8, and a guide rod 10. The mounting plate 1 and mounting plate 2 can be folded using a fixing component 3 and a rotating component 4. At this time, the surface of the clamp 5 contacts the inclined surface of the clamp block 7, causing the clamp block 7 to move on the surface of the guide rod 10 and compress the spring 8. Then, under the action of the spring 8, the clamp block 7 resets, locking the clamp 5. This allows the device to easily fold the mounting plate 1 and mounting plate 2, improving its portability and facilitating storage and transportation. A fixing post 23 is installed on the inner wall of the mounting plate 1 and mounting plate 2, connecting the cylinder 14 to the groove between the mounting plate 1 and mounting plate 2. Then, a fixing bolt 24 connects the connecting arm 22 and the fixing post 23, achieving rapid installation and disassembly of the detection components.

[0041] It should be noted that the detection component contacts the ground through the roller component 18. When the device moves, the spring 16 keeps the roller component 18 in contact with the ground. When the mounting rod 17 rises and falls according to the rise and fall of the roller component 18, the displacement sensor 20 can detect the displacement. The displacement sensor 20 is a pull rod type.

[0042] The working principle of the above embodiments is as follows:

[0043] When the device is needed, first press the pressing member 9 to move the locking block 7 on the surface of the guide rod 10 and compress the spring 8. At this time, the locking member 5 is released from its limit, and the mounting plate 1 and mounting plate 2 can be folded open through the connection of the fixing member 3 and the rotating member 4. After opening, connect the cylinder 14 with the groove between the mounting plate 1 and mounting plate 2, align the connecting arm 22 with the corresponding fixing post 23, and then rotate the corresponding fixing bolt 24 to connect with the fixing post 23. This will fix the cylinder 14 to the mounting plate 1 and mounting plate 2. Between the two plates 2, the movement of the device causes the roller 18 to move. The undulation of the roller 18 causes the mounting rod 17 to rise and fall, which in turn causes the circular plate 19 to move the displacement sensor 20. The displacement sensor 20 can detect the deflection of the road surface. After the detection is completed, the cylinder 14 is disassembled by fixing bolts 24. Then, the mounting plate 1 and the mounting plate 2 are folded. The folding is achieved by connecting the clip 5 and the clip 7. The device can then be easily lifted by the handle slot 13. The folded device is easy to store and transport.
