Description

Technical Field

[0001] This utility model relates to the field of road surface monitoring device installation technology, and in particular to a lightweight installation structure for a real-time road surface monitoring device. Background Technology

[0002] In the highway traffic operation management and safety assurance system, real-time road surface monitoring technology, as a core technology system integrating road condition perception, data collection, and risk early warning, achieves early identification of road surface defects and dynamic early warning of traffic risks by capturing key state parameters such as road surface smoothness, cracks, water accumulation, and ice and snow in real time, combined with sensor data processing algorithms. This lays the foundation for highway maintenance decision-making, emergency rescue dispatch, and traffic safety assurance. The stable deployment and efficient operation and maintenance of road surface monitoring devices, as a key link in the practical application of real-time road surface monitoring technology, mainly ensures the continuous and reliable operation of the monitoring devices in complex outdoor environments through reasonable installation structure design. Against the backdrop of large-scale highway network construction and refined maintenance, the installation and operation efficiency of real-time road surface monitoring devices directly determines the application benefits of monitoring technology. Currently, the industry commonly uses bolt-fixed installation for road surface monitoring devices, but this method has some drawbacks in actual operation. Road surface monitoring scenarios are mostly in areas with high traffic flow, such as highways and urban main roads. Installation operations need to minimize road occupancy time to reduce traffic impact. When using traditional bolt-fixed installation, the bolt connection structure limits the installation carrier. It is necessary to drill and tap holes before fixing the device with multiple bolts. The entire installation process is too time-consuming, and disassembly requires tools, which seriously affects operation and maintenance efficiency. Moreover, the metal bolts used in traditional installation methods are exposed to the outdoors for a long time and are susceptible to corrosion from rainwater and salt, causing the bolts to seize up and jam with the mounting holes. Forced disassembly can easily damage the installation structure, which cannot meet the high-quality requirements of real-time road surface monitoring technology for rapid deployment and efficient operation and maintenance of devices. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a lightweight installation structure for a real-time road surface monitoring device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a lightweight installation structure for a real-time road surface monitoring device, comprising a detection device body and a mounting base plate, wherein a connecting arm is fixedly installed in the middle of one side of the detection device body, and a clamping plate is fixedly installed at the other end of the connecting arm, and a plurality of limiting holes are evenly opened on the inner wall of the clamping plate; a gear box is fixedly installed in the middle of the mounting base plate, and a slot is opened at the end of the gear box, and the clamping plate is inserted and installed inside the slot. The gearbox has a hollow cavity inside, and a worm gear is installed inside the hollow cavity. Four arc-shaped guide grooves are evenly distributed on the surface of the worm gear. Multiple slide rails are evenly distributed on the inner end of the slot. The inner side of the slide rail is connected to the inside of the hollow cavity. I-shaped sliders are slidably installed inside each slide rail. A positioning pin is fixedly installed on the end of the I-shaped slider away from the worm gear. The positioning pin is adapted to the limiting hole.

[0005] Preferably, a T-shaped slide bar is fixedly installed at the end of the I-shaped slider away from the positioning pin, and the T-shaped slide bar is slidably installed inside the arc-shaped guide groove.

[0006] Preferably, a drive worm is rotatably mounted at both ends of the inner wall of the hollow cavity, and the middle part of the drive worm is meshed with the side part of the worm wheel.

[0007] Preferably, a drive handle is provided on the outer side of the gear box, one end of the drive handle passes through the gear box and is fixedly connected to one end of the drive worm, and the through connection between the drive handle and the gear box is a rotatable connection.

[0008] Preferably, a shaft post is fixedly installed at the axial center of the worm gear, and the two ends of the shaft post are respectively rotatably installed at the two ends of the inner side of the hollow cavity.

[0009] Preferably, the number of arc-shaped guide grooves is the same as the number of I-shaped sliders, and the positions of the arc-shaped guide grooves correspond to the positions of the multiple T-shaped sliders.

[0010] Preferably, the number of limiting holes is four, and when the card plate is connected to the inside of the card slot, the positions of the multiple positioning pins correspond to the positions of the limiting holes respectively.

[0011] Preferably, a plurality of positioning protrusions are uniformly fixedly installed on the outer surface of the card plate, and the interior of the card slot is adapted to the card plate and the positioning protrusions on its side.

[0012] In summary, this utility model has the following beneficial effects: 1. This utility model uses a rotating drive handle to drive the active worm gear to rotate. The active worm gear meshes with and drives the worm wheel to rotate around the shaft column. The arc-shaped guide groove on the surface of the worm wheel drives the I-shaped slider to slide along the slide rail through the T-shaped slide rod, so that the positioning pin rod can be inserted into or disengaged from the limiting hole of the card plate at the same time. This enables the rapid connection and disassembly of the detection device body and the mounting base plate. This allows a single person to complete the installation or maintenance work in a short time, which greatly shortens the time that the road monitoring device occupies the road in areas with heavy traffic, reduces the impact on traffic flow, avoids the damage to the installation structure caused by the corrosion of traditional bolts, reduces the cost of replacing parts during the operation and maintenance of the device, and improves the overall operation and maintenance efficiency. 2. This utility model integrates transmission components such as worm gears and active worms, as well as locking components such as I-shaped sliders and positioning pins, into the gearbox. The gearbox can form a closed protection for these core components. In complex outdoor environments, it can effectively prevent rainwater, salt, dust, and other substances from corroding the transmission and locking components, avoiding jamming failures due to rust or dust accumulation. This ensures smooth transmission and reliable locking, extends the service life of the components, reduces the risk of monitoring device downtime due to component damage, and ensures the continuity and stability of real-time road monitoring data collection, providing continuous data support for highway maintenance decisions and traffic safety early warning. 3. This utility model achieves locking by driving the positioning pin to engage with the limiting hole through the meshing transmission of a worm gear. The worm gear structure has a reverse self-locking characteristic. Without external force to rotate the drive handle, the worm gear will not reverse due to external vibration or collision, thus ensuring that the positioning pin is always stably inserted into the limiting hole. This effectively avoids the road monitoring device from becoming loose or shifting due to external interference such as vehicle vibration or accidental collisions. It ensures the installation stability of the detection device body under complex outdoor working conditions, ensures that the monitoring device can continuously and accurately capture road condition parameters, and improves the accuracy and reliability of real-time road monitoring data.

[0015] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0016] The specific embodiments of this utility model are described below with reference to the accompanying drawings: Example: Reference Figures 1-6 A lightweight installation structure for a real-time road surface monitoring device includes a detection device body 1 and a mounting base plate 2. A connecting arm 101 is fixedly installed in the middle of one side of the detection device body 1, and a clamping plate 102 is fixedly installed in the other end of the connecting arm 101. A plurality of limiting holes 104 are evenly opened on the inner wall of the clamping plate 102. A gear box 201 is fixedly installed in the middle of the mounting base plate 2. A slot 202 is opened at the end of the gear box 201, and the clamping plate 102 is inserted into the slot 202. The gear box 201 has a hollow cavity 5 inside, and a worm gear 6 is installed inside the hollow cavity 5. Four arc-shaped guide grooves 602 are evenly opened on the surface of the worm gear 6. Multiple slide rails 3 are evenly opened on the inner end of the slot 202. The inner side of the slide rail 3 is connected to the inside of the hollow cavity 5. I-shaped sliders 4 are slidably installed inside each slide rail 3. A positioning pin 401 is fixedly installed on the side of the I-shaped slider 4 away from the worm gear 6. The positioning pin 401 is adapted to the limiting hole 104.

[0017] Specifically: In actual use, the detection device body 1 is used to capture key status parameters such as road surface smoothness, cracks, and water accumulation in real time. The multiple limiting holes 104 opened on the inner wall of the card plate 102 provide an adaptation structure for subsequent locking operations. Through the insertion and cooperation of the card plate 102 and the card slot 202, the position alignment of the detection device body 1 and the mounting base plate 2 can be initially achieved, avoiding the inability of the positioning pin 401 to accurately connect due to positional offset during subsequent locking.

[0018] The gearbox 201 serves as a protective and mounting carrier for the transmission and locking components. Its internal hollow cavity 5 provides ample space for the rotation of the worm gear 6, while simultaneously creating a sealed protection for the internal worm gear 6 and subsequent transmission components, reducing the erosion of these components by outdoor rain and dust. The slot 202 at the end of the gearbox 201 matches the clamping plate 102, forming the structural basis for the initial docking of the detection device body 1 and the mounting base plate 2, ensuring that the clamping plate 102 can be smoothly inserted and maintain its initial positioning. The worm gear 6 is the core component of the transmission system. Four evenly spaced arc-shaped guide grooves 602 on its surface provide a guiding path for the subsequent sliding of the I-shaped slider 4. Through the rotation of the worm gear 6 itself, the arc-shaped guide grooves 602 apply driving force to the mating components, converting the rotational motion into the linear sliding of the I-shaped slider 4, providing the power basis for the locking operation.

[0019] Multiple slide rails 3 on the inner end of the slot 202 provide sliding trajectory constraints for the I-shaped slider 4, ensuring that the I-shaped slider 4 can slide smoothly in a fixed direction and avoid jamming or deviation during sliding. At the same time, the inner side of the slide rail 3 is connected to the hollow cavity 5, so that the I-shaped slider 4 can form a linkage with the mating parts on the worm gear 6 side, ensuring smooth power transmission. The I-shaped slider 4 is the execution part of the locking operation. The positioning pin 401 fixed on the end away from the worm gear 6 is adapted to the limiting hole 104 on the card plate 102. By sliding the I-shaped slider 4 along the slide rail 3, the positioning pin 401 can be driven to insert or disengage from the limiting hole 104, ultimately realizing the locking or unlocking of the detection device body 1 and the mounting base plate 2, ensuring the stability of the detection device body 1 after installation and convenient disassembly during subsequent operation and maintenance.

[0020] In use, the clamping plate 102 at the end of the connecting arm 101 on the side of the detection device body 1 is inserted into the slot 202 at the end of the gear box 201 to complete the initial positioning. Then, the worm gear 6 is driven to rotate in the hollow cavity 5 of the gear box 201 by external driving force. The arc-shaped guide groove 602 on the surface of the worm gear 6 will drive the I-shaped slider 4 to slide along the slide rail 3, so that the positioning pin 401 at the end of the I-shaped slider 4 is inserted into the limiting hole 104 of the clamping plate 102, thereby locking and fixing the detection device body 1 to the mounting base plate 2. When disassembly is required, the worm gear 6 is driven to rotate in the opposite direction, and the I-shaped slider 4 drives the positioning pin 401 to disengage from the limiting hole 104, so that the clamping plate 102 can be pulled out from the slot 202, thus completing the disassembly of the detection device body 1.

[0021] A T-shaped slide bar 603 is fixedly installed at the end of the I-shaped slider 4 away from the positioning pin 401. The T-shaped slide bar 603 is slidably installed inside the arc-shaped guide groove 602. A drive worm is rotatably installed at both ends of the inner wall of the hollow cavity 5. The middle part of the drive worm is meshed with the side of the worm wheel 6. A drive handle 701 is provided on the outside of the gear box 201. One end of the drive handle 701 passes through the gear box 201 and is fixedly connected to one end of the drive worm 7. The through connection between the drive handle 701 and the gear box 201 is a rotatable connection. Specifically, in actual use, the T-shaped slide bar 603 is a key transmission component connecting the I-shaped slider 4 and the worm gear 6. One end of it is fixed to the end of the I-shaped slider 4 away from the positioning pin 401, and the other end is slidably installed in the arc-shaped guide groove 602 on the surface of the worm gear 6. This can convert the rotational motion of the worm gear 6 into the linear sliding of the I-shaped slider 4, ensuring that the worm gear 6 can stably drive the I-shaped slider 4 to move along the slide rail 3 when it rotates. The drive worm installed on the inner wall of the hollow cavity 5 can accurately transmit the rotational force input by the drive handle 701 to the worm gear 6 by meshing with the side of the worm gear 6. At the same time, by utilizing the meshing characteristics of the worm and the worm gear 6, the direction of power is converted, so that the lateral rotational force of the drive handle 701 is converted into the longitudinal rotational force of the worm gear 6, providing a stable power source for the subsequent sliding of the I-shaped slider 4.

[0022] During operation, rotating the drive handle 701 drives the active worm gear 7 to rotate within the hollow cavity 5 of the gear box 201. The active worm gear 7 drives the worm wheel 6 to rotate through meshing. As the worm wheel 6 rotates, the arc-shaped guide groove 602 on its surface generates a guiding thrust on the internal sliding T-shaped slide bar 603, pushing the T-shaped slide bar 603 to drive the I-shaped slider 4 to slide along the slide rail 3 towards the clamping plate 102. Finally, the positioning pin 401 at the end of the I-shaped slider 4 is inserted into the limiting hole 104 of the clamping plate 102 to lock it. When unlocking is required, rotating the drive handle 701 in the opposite direction causes the active worm gear 7 to drive the worm wheel 6 to rotate in the opposite direction. The arc-shaped guide groove 602 pulls the I-shaped slider 4 to slide in the opposite direction through the T-shaped slide bar 603, and the positioning pin 401 disengages from the limiting hole 104, completing the unlocking process.

[0023] A shaft post 601 is fixedly installed at the axial position of the worm gear 6. The two ends of the shaft post 601 are respectively rotatably installed at the two ends of the hollow cavity 5, providing a precise rotation fulcrum for the worm gear 6. This ensures that the worm gear 6 can make a stable circular motion around the shaft post 601 when driven by the meshing force of the active worm 7, avoiding radial offset or wobbling of the worm gear 6 due to the lack of a fixed fulcrum. This ensures the accuracy of subsequent transmission with the T-shaped slide bar 603. The number of arc-shaped guide grooves 602 is the same as the number of I-shaped slide bars 4, and the positions of the arc-shaped guide grooves 602 correspond to the positions of multiple T-shaped slide bars 603. When the worm gear 6 rotates, each arc-shaped guide groove 602 can simultaneously apply a guiding force to the matched T-shaped slide bar 603, driving all I-shaped slide bars 4 to slide synchronously along the slide rail 3. This ensures that multiple sets of positioning pins 401 can be simultaneously inserted into or disengaged from the limiting holes 104 of the card plate 102, improving the stability and synchronization of locking or unlocking. There are four limiting holes 104. When the card plate 102 is connected to the inside of the card slot 202, multiple positioning pins 401 correspond to the positions of the limiting holes 104 respectively. Multiple positioning protrusions 103 are evenly fixed on the outer surface of the card plate 102. The inside of the card slot 202 is adapted to the card plate 102 and the positioning protrusions 103 on its side. During the process of inserting the card plate 102 into the card slot 202, the positioning protrusions 103 can form a fitting constraint with the fitting structure of the inner wall of the card slot 202, restricting the lateral and longitudinal movement of the card plate 102 in the card slot 202, avoiding positional deviation after the card plate 102 is inserted, thereby ensuring that the four limiting holes 104 on the card plate 102 can be accurately aligned with the positioning pins 401, laying the foundation for the synchronous insertion of multiple sets of positioning pins 401 into the limiting holes 104, and reducing locking failure or component wear caused by initial positioning deviation.

[0024] The working principle of this utility model is as follows: In specific use, before installing the real-time road monitoring device, the mounting base plate 2 is first fixed on the pre-set mounting carrier such as the roadside guardrail or curbstone to complete the construction of the installation foundation; then, holding the detection device body 1, the clamping plate 102 at the end of the side connecting arm 101 is aligned with the slot 202 at the end of the gear box 201 on the mounting base plate 2. Utilizing the compatibility between the positioning protrusion 103 on the outside of the clamping plate 102 and the slot 202, the clamping plate 102 is smoothly inserted into the slot 202 until the clamping plate 102 is completely attached to the inner wall of the slot 202, thus achieving the initial positioning of the detection device body 1 and the mounting base plate 2.

[0025] After the card plate 102 completes its initial positioning, the drive handle 701 on the outside of the gear box 201 is rotated. The drive handle 701 drives the active worm gear 7, which is fixedly connected to one end of its inner side, to rotate in the hollow cavity 5 inside the gear box 201. Since the active worm gear 7 meshes with the side of the worm wheel 6, when the active worm gear 7 rotates, it will drive the worm wheel 6 to rotate synchronously around the shaft column 601 at its axis. The surface of the worm wheel 6 is provided with arc-shaped guide grooves 602, which are the same number as the I-shaped slider 4. The end of the I-shaped slider 4 away from the positioning pin 401 is fixed with a T-shaped slide rod 603 that is slidably installed in the arc-shaped guide groove 602. As the worm wheel 6 rotates, the arc-shaped guide groove 602 guides the I-shaped slider 4 through the T-shaped slide rod 603, causing the I-shaped slider 4 to slide along the slide rail 3 opened at the inner end of the card slot 202 towards the card plate 102.

[0026] During the sliding process of the I-shaped slider 4, the positioning pin 401 on its side moves synchronously with the I-shaped slider 4 until the positioning pin 401 is precisely inserted into the preset limiting hole 104 on the inner wall of the card plate 102. At this time, the drive handle 701 is stopped from rotating. With the help of the reverse self-locking characteristic of the worm gear 6, the worm gear 6 maintains its current position and does not reverse. The I-shaped slider 4 and the positioning pin 401 also remain stably in their current state, thus completing the secure locking of the detection device body 1 and the mounting base plate 2 and realizing the installation of the real-time road monitoring device.

[0027] When the main body 1 of the testing device needs to be disassembled for maintenance, the drive handle 701 is rotated in the reverse direction. The active worm gear 7 drives the worm wheel 6 to rotate in the reverse direction. The arc-shaped guide groove 602 drives the I-shaped slider 4 to slide along the slide rail 3 away from the clamping plate 102 through the T-shaped slide rod 603. The positioning pin 401 then disengages from the limiting hole 104, releasing the locking restriction on the clamping plate 102. At this time, the clamping plate 102 can be pulled out from the clamping groove 202, thus completing the disassembly of the main body 1 of the testing device, so that the device can be inspected, maintained or replaced in the future.
