Description

Technical Field

[0001] This utility model relates to the field of road surface settlement detection technology, and more specifically, to a highway road surface settlement detection device. Background Technology

[0002] Road surface settlement refers to the subsidence of a road surface caused by deformation of underground soil layers or geological activity. This phenomenon has a significant impact on urban construction and geological safety. Therefore, accurate and timely monitoring of road surface settlement is crucial. Road surface settlement detection devices have emerged as an important tool for monitoring road surface settlement and assessing geological safety. These devices play a vital role in ensuring urban geological safety and promoting urban planning and construction. With continuous technological advancements and innovations, future road surface settlement detection devices will possess higher precision, stronger real-time capabilities, and more intelligent early warning capabilities, making a greater contribution to social development and engineering construction.

[0003] For example, Chinese Patent (Announcement No.: CN221192886U) discloses a road settlement monitoring device, specifically relating to the technical field of road settlement monitoring devices. It includes a base, on which a reduction monitoring component is mounted. The reduction monitoring component includes a turntable mounted on the base, a support rod mounted on the turntable, and a top rod mounted on the support rod. This utility model, by setting up the reduction monitoring component, measures angle change data through a monitoring target. Using the angle change data and the vertical distance from the road surface to the monitoring target, the road settlement is calculated. The rotating shaft drives the connecting block to rotate, thereby changing the angle of the monitoring target. The turntable then rotates to adjust the angle of the monitoring target again, ensuring that the monitoring area of ​​the target is in a wind-resistant area and in the direction of rain or snow, reducing wear and tear caused by severe weather during use. It also facilitates angle adjustment of the monitoring target during monitoring, increasing the versatility of the device in use.

[0004] However, this device is relatively complex to use. When monitoring settlement, the angle of the monitoring target changes, and the angle change data is measured. The settlement of the road surface is calculated using the angle change data and the vertical distance from the road surface to the monitoring target. If the amount of data to be measured is large, it takes a long time to complete the test, which is time-consuming, labor-intensive and inefficient. Therefore, a highway road settlement detection device is proposed to solve the above problems. Utility Model Content

[0005] In view of the shortcomings of the existing devices, this utility model aims to provide a highway pavement settlement detection device, which solves the problems that the existing detection devices are relatively complicated to use, take a long time to detect, are time-consuming and labor-intensive to operate, and have insufficient detection efficiency.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A highway pavement settlement detection device includes a housing, a chassis fixed to the bottom of the housing, a plurality of rollers hinged to the bottom of the chassis, two telescopic components that can improve detection efficiency inside the housing, a detection rod for easy observation at the far ends of the two telescopic components, and a rotating cylinder engaged at the close ends of the two telescopic components.

The inner side of the rotating cylinder has multiple internal teeth fixed, and the multiple external teeth mesh with the multiple internal teeth. A battery pack is fixed on the rear side of the outer casing.

[0011] Furthermore, both sides of the rotating cylinder are rotatably connected to the outer shell via connecting bearings, and multiple friction blocks are fixed on the outer surface of the rotating cylinder.

[0012] Furthermore, each of the feedback units includes a connecting rod rotatably connected to the rotating bearing. Each connecting rod is provided with a through hole, a moving groove, a gear groove, and a telescopic hole. The two sides of the through hole are respectively connected to the moving groove and the gear groove. The side of the moving groove away from the through hole is connected to the telescopic hole. Each gear groove is provided with a power block, and each telescopic hole is provided with a receiving block.

[0013] Furthermore, an alarm light is fixed to the top of each connecting rod, a limit rod is fixed to the bottom of each connecting rod, and two limit holes are opened on the outer shell, which are respectively adapted to the two limit rods.

[0014] Furthermore, the outer shell has two threaded holes, each of which is fixed with an internal threaded strip that is compatible with the external thread.

[0015] Furthermore, each of the power blocks consists of a rotating rod, a power gear, and an elastic steel coil. The two ends of the rotating rod are rotatably connected to the front and rear side walls of the gear groove through bearings. The outer surface of the rotating rod is fixed with the power gear and the elastic steel coil in sequence from front to back. The outer surface of the elastic steel coil is fixed to the outer shell. Each of the detection rods is fixed with a straight tooth, which meshes with the power gear.

[0016] Furthermore, the receiving block includes a pressure sensor fixed to the bottom wall of the telescopic hole, a compression spring fixed to the end of the pressure sensor near the detection rod, a relief block fixed to the end of the compression spring away from the pressure sensor, and a squeezing block fixed to the end of the detection rod away from the power block, the squeezing block and the relief block being adapted to each other.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This invention enables efficient detection through the cooperation of a telescopic component and a detection rod. When encountering uneven road surfaces, the action of the power block will keep the detection rod in close contact with the ground. As the road surface settles, the detection rod will move down, further pressing against the receiving block, thus allowing staff to quickly locate the settlement and achieve efficient detection.

[0023] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0024] Example:

[0025] like Figures 1 to 3As shown, a highway road settlement detection device in this embodiment includes a housing 1, a chassis 2 fixed to the bottom of the housing 1, and multiple rollers hinged to the bottom of the chassis 2. The rollers can improve the overall stability and portability of the device, and ensure that the staff can easily push it when it needs to be moved. The housing 1 is provided with two telescopic components 3 that can improve the detection efficiency. The ends of the two telescopic components 3 that are far apart are provided with detection rods 4 that are easy to observe. The ends of the two telescopic components 3 that are close to each other are engaged with a rotating cylinder 5.

[0026] In this embodiment, the outer casing 1 has two threaded holes, and an internal threaded bar is fixed in each threaded hole. The internal thread is compatible with the external thread. The threaded connection can ensure the stable operation of the device, and when the rotating cylinder 5 is rotated, the threaded rod 301 can be moved while rotating.

[0027] In this embodiment, the device achieves efficient detection through the cooperation of the rotating cylinder 5 and the telescopic component 3. By rotating the rotating cylinder 5, the fine-tuning of the detection rod 4 can be stably performed. Through the cooperation of the telescopic component 3 and the detection rod 4, efficient detection can be achieved.

[0028] In this embodiment, in order to improve detection efficiency, each telescopic component 3 includes a threaded rod 301 that is threadedly connected to the outer shell 1. A rotating bearing 302 is fixed at the end of the threaded rod 301 away from the outer shell 1. The rotating bearing 302 can isolate the rotation of the threaded rod 301 while retaining the movement of the threaded rod 301, thereby further improving detection efficiency and helping staff to quickly find the settlement position. A feedback part 303 is provided at the end of the rotating bearing 302 away from the threaded rod 301.

[0029] In this embodiment, an external threaded strip is fixed on the outer surface of each threaded rod 301, and multiple external teeth are fixed on the outer surfaces of the two threaded rods 301 on the side that is close to each other. Multiple internal teeth are fixed on the inner side of the rotating cylinder 5. The multiple external teeth mesh with the multiple internal teeth. By meshing the rotating cylinder 5 and the threaded rod 301, it can be ensured that the power of the rotating cylinder 5 can be continuously transmitted to the threaded rod 301 when the threaded rod 301 moves. A battery pack is fixed on the rear side of the outer casing 1.

[0030] In this embodiment, each feedback unit 303 includes a connecting rod 3031 rotatably connected to the rotating bearing 302. Each connecting rod 3031 is provided with a through hole, a moving groove, a gear groove, and a telescopic hole. The two sides of the through hole are respectively connected to the moving groove and the gear groove. Through the connection of the through hole, the moving groove, the gear groove, and the telescopic hole, power can be transmitted, thereby achieving the purpose of quickly detecting the settlement position. The side of the moving groove away from the through hole is connected to the telescopic hole. Each gear groove is provided with a power block 3032, and each telescopic hole is provided with a receiving block 3033.

[0031] In this embodiment, an alarm light is fixed to the top of each connecting rod 3031. The alarm light can help the user quickly react to the settlement position and further improve the settlement efficiency. A limit rod is fixed to the bottom of each connecting rod 3031. Two limit holes are opened on the outer shell 1. The two limit holes are adapted to the two limit rods respectively. The limit rods are inserted into the limit holes, which can further improve the stability of the connecting rod 3031.

[0032] In this embodiment, each power block 3032 consists of a rotating rod, a power gear, and an elastic steel coil. The two ends of the rotating rod are rotatably connected to the front and rear side walls of the gear groove through bearings. The outer surface of the rotating rod is fixed with the power gear and the elastic steel coil from front to back. The elastic steel coil has good elasticity and can always provide good power to the power gear, so that the power gear always meshes with the detection rod 4 and keeps the detection rod 4 in continuous contact with the ground. The outer surface of the elastic steel coil is fixed to the outer shell 1. Each detection rod 4 is fixed with a straight tooth, which meshes with the power gear.

[0033] In this embodiment, the receiving block 3033 includes a pressure sensor fixed to the bottom wall of the telescopic hole. A compression spring is fixed to one end of the pressure sensor near the detection rod 4. The pressure sensor can record the force on the compression spring. When the spring force exceeds the limit range, it will trigger the alarm light. A relief block is fixed to one end of the compression spring away from the pressure sensor. A squeezing block is fixed to one end of the detection rod 4 away from the power block 3032. The squeezing block and the relief block are adapted to each other. The squeezing block and the relief block are both arc-shaped at their opposite points. The arc shape can make the movement of the relief block smoother.

[0034] In this embodiment, a tire is rotatably connected to the bottom of each detection rod 4, and scale lines are drawn on each detection rod 4. The scale lines can help users quickly perform settlement checks and further achieve efficient detection. The left and right sides of the rotating cylinder 5 are rotatably connected to the outer shell 1 through connecting bearings. Multiple friction blocks are fixed on the outer surface of the rotating cylinder 5. The friction blocks can help users use the rotating cylinder 5 more conveniently and quickly, and further help users perform efficient detection.

[0035] In this embodiment, the cooperation between the power block 3032 and the receiving block 3033 ensures the efficient and stable operation of the device, guarantees that the device can respond quickly when it encounters a road surface settlement location, and further improves inspection efficiency.

[0036] In this embodiment, when in use, the device is first moved. When it encounters a road surface settlement location, the device will respond quickly under the combined action of the power block 3032 and the receiving block 3033, ensuring that the user can find the settlement location in time. Then, the device can be finely adjusted by rotating the rotating cylinder 5 to quickly find the accurate location of the settlement and perform a quick check with the scale line.

[0037] It should be noted that all electrical components mentioned in this article are electrically connected to the controller and power supply. The control method of this utility model is controlled by the controller. The control circuit of the controller can be implemented by those skilled in the art through simple programming. The power supply provided by the storage battery is also common knowledge in the field. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail here.

[0038] The working principle of this highway pavement settlement detection device is as follows:

[0039] First, the staff pushes the device. When the device encounters a settlement area, the elastic steel coil causes the power gear to rotate, further ensuring that the detection rod 4 remains in close contact with the ground. Due to road settlement, the detection rod 4 will move downwards, causing the clearance block to move away from the detection rod 4. As the clearance block moves, it causes the compression spring to accumulate elastic potential energy. At the same time, when the pressure sensor senses pressure exceeding a certain range, it will trigger the alarm light, further helping the user to quickly locate the settlement position. The position of the detection rod 4 can be adjusted by moving the device or rotating the rotating cylinder 5 to accurately locate the settlement position. At this point, the settlement detection can be completed by directly observing the scale line. This device has high detection efficiency, is easy to use, and can greatly reduce the operational difficulty for staff.

[0040] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
