Description

Technical Field

[0001] This utility model relates to the field of roadbed testing, and more specifically, to a high-precision positioning intelligent roadbed compaction testing device. Background Technology

[0002] In highway construction, compaction is a crucial step, a vital process for gradually densifying the pavement material. The degree of compaction is a key criterion for evaluating compaction quality. Traditional methods for testing compaction degree primarily include the ring cutter method, sand cone method, and core drilling method. These methods typically involve post-construction acceptance of compaction quality, rather than controlling it during construction, resulting in a lag and impacting construction progress. Therefore, the more common approach now is to install compaction degree sensors on the road roller. These sensors continuously collect the acceleration signals of the vibrating drum, process the signals in real time, and calculate the compaction degree index.

[0003] In addition, to further improve the compaction detection performance of road rollers, antennas are installed on them to record the compaction path. Currently, most antennas are directly mounted on the top of the cab. However, due to the harsh working environment of road rollers and the numerous bumpy road sections during operation, the antennas are not effectively buffered, which greatly affects their lifespan. Utility Model Content

[0004] In view of this, the present invention provides a high-precision positioning intelligent compaction detection device for roadbed with a positioning antenna buffer and shock absorption structure, which can reduce the vibration of the positioning antenna during the operation of the road roller and improve the service life of the positioning antenna.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A high-precision positioning intelligent roadbed compaction detection device includes a body, a pressure roller mounted on the front side of the body, a compaction sensor mounted on the roller's shaft, a traveling wheel mounted on the rear side of the body, a driver's cab mounted on the body, and a data processor mounted in the driver's cab; it also includes a positioning antenna, which is mounted on the outer top of the driver's cab via a vibration damping device. The vibration damping device includes a longitudinal vibration damping component and a transverse vibration damping component, with the transverse vibration damping component mounted on the longitudinal vibration damping component. The longitudinal vibration damping component is located on the outer top of the driver's cab, and the transverse vibration damping component is connected to a mounting base. The positioning antenna is mounted on the mounting base.

[0007] In the aforementioned technical solution, by integrating a compaction sensor and a positioning antenna onto the road roller, the roller can record its compaction path via the antenna and monitor the number of compaction passes in real time, ensuring thorough compaction. This also helps optimize the construction process, reducing unnecessary movement and repetitive work, and further improving construction efficiency. Furthermore, the vibration damping device, composed of longitudinal and transverse damping components, effectively absorbs and disperses vibrations from uneven road surfaces, achieving omnidirectional vibration damping for the positioning antenna, protecting it from damage, and helping to reduce the vibration experienced by the antenna during operation, thus extending its service life.

[0008] Optionally, in one possible implementation, the longitudinal damping component includes a movable plate, a plurality of corresponding positioning columns, and a plurality of elastic elements. One end of each positioning column is fixed to the cab, and the other end passes through the movable plate. The plurality of elastic elements are correspondingly sleeved on the plurality of positioning columns, and the elastic elements are located between the bottom of the movable plate and the cab. The lateral damping component and the mounting base are both located on the top of the movable plate.

[0009] In the above technical solution, the longitudinal damping components can absorb and release vertical vibration energy from the ground. When the road roller travels on a bumpy road, the elastic element can deform and be cushioned, thereby effectively reducing the vibration experienced by the positioning antenna. The positioning post can also serve as a guide mechanism for the movable plate, allowing the movable plate to slide only up and down along the positioning post, which also facilitates the positioning and installation of the movable plate.

[0010] Alternatively, in one possible implementation, the movable plate is movable relative to the positioning post, the outer periphery of the positioning post being threadedly connected to an adjusting block, the adjusting block being located on top of the movable plate and abutting against the movable plate.

[0011] In the above technical solution, the adjusting block enables precise adjustment of the vibration damping effect. The adjusting block can be easily rotated to change its position on the positioning column, thereby adjusting the pressure on the movable plate and consequently the compression degree of the elastic element. This allows technicians to quickly and accurately adjust the vibration damping performance according to specific needs, adapting to different working environments and operational requirements.

[0012] Optionally, in one possible implementation, there are multiple lateral damping components, which are arranged at intervals around the outer periphery of the mounting base.

[0013] In the above technical solution, the setting of multiple lateral damping components realizes multi-directional damping protection for the positioning antenna, which can effectively absorb vibrations from the ground or lateral vibrations generated when the road roller is running, reduce the load pressure of a single lateral damping component, and, together with the longitudinal damping components, can form all-round damping protection for the positioning antenna.

[0014] Optionally, in one possible implementation, the lateral damping assembly includes a fixed block and a hydraulic damper, with both ends of the hydraulic damper connected to the fixed block and the mounting base, respectively.

[0015] In the aforementioned technical solution, the hydraulic damper, as the core component of the lateral shock absorption assembly, possesses excellent shock absorption and energy absorption capabilities. When the road roller travels on uneven ground or performs compaction operations, the hydraulic damper can quickly respond and absorb vibrations and impacts from the ground. Furthermore, the hydraulic damper is typically equipped with adjustable valves or throttling devices, allowing technicians to dynamically adjust its shock absorption performance according to the specific construction environment and operational requirements.

[0016] Optionally, in one possible implementation, the lateral damping assembly includes a fixed block, a sleeve disposed on the fixed block, a buffer member disposed within the sleeve, and a top rod disposed on the mounting base, the top rod being movably inserted into the sleeve and abutting against the buffer member.

[0017] In the above technical solution, when the road roller is subjected to vibration or impact, the mounting base and positioning antenna will shake. When the mounting base shifts laterally, the top rod will slide inside the sleeve and achieve buffering and shock absorption under the action of the buffer component, thereby avoiding severe impact on the positioning antenna. Its structure is simple and effective, and it is also easy to install.

[0018] Alternatively, in one possible implementation, the elastic element and the buffer element are metal springs or elastic rubber.

[0019] In the above technical solution, both the metal spring and the elastic rubber possess high elasticity and good resilience. When subjected to vibration, they can respond quickly and absorb energy, and rapidly return to their original shape after the external force disappears, thus maintaining the stability and reliability of the shock absorption system. Furthermore, both the metal spring and the elastic rubber have high wear resistance and fatigue resistance, enabling them to support long-term operation.

[0020] Optionally, in one possible implementation, the mounting base is provided with a plurality of reinforcing ribs located on the outer periphery of the positioning antenna.

[0021] In the above technical solution, the reinforcing ribs are set on the outer periphery of the positioning antenna, which can strengthen the support of the positioning antenna, reduce the shaking of the positioning antenna itself, and make the antenna more stable and reliable.

[0022] Alternatively, in one possible implementation, the bottom of the mounting base is placed on the movable plate, and the bottom of the mounting base is provided with a wear-resistant layer.

[0023] In the above technical solution, since the mounting base is in contact with the movable plate, the road roller will cause frequent relative sliding between the mounting base and the movable plate during operation. Therefore, the wear-resistant layer can effectively reduce the friction and wear between the mounting base and the movable plate, thereby improving the service life of the shock absorption device.

[0024] Alternatively, in one possible implementation, a protective cover is detachably mounted on the top of the outer side of the cab, the protective cover covering the outside of the shock absorption device, and the protective cover also having a through hole for the positioning antenna to pass through.

[0025] In the aforementioned technical solution, the working environment of the road roller is relatively harsh, usually accompanied by a large amount of sand and dust. The protective cover can effectively protect the shock absorption device from damage caused by external environmental factors such as sand and dust, extending the service life of the shock absorption device and reducing failures and maintenance costs caused by external environmental factors. Furthermore, the detachable design of the protective cover also makes maintenance and inspection of the shock absorption device more convenient. Attached Figure Description

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0033] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0034] Please refer to Figure 1 and Figure 2 This embodiment provides a high-precision positioning intelligent roadbed compaction detection device, including a body 1, a pressure roller 2 mounted on the front of the body 1, a compaction sensor mounted on the axle of the pressure roller 2, a traveling wheel 3 mounted on the rear of the body 1, a driver's cab 4 mounted on the body 1, and a data processor 5 installed inside the driver's cab 4; it also includes a positioning antenna 6, which is mounted on the outer top of the driver's cab 4 via a shock-absorbing device 7. The shock-absorbing device 7 includes a longitudinal shock-absorbing component 71 and a transverse shock-absorbing component 72. The transverse shock-absorbing component 72 is mounted on the longitudinal shock-absorbing component 71, and the longitudinal shock-absorbing component 71 is mounted on the outer top of the driver's cab 4. The transverse shock-absorbing component 72 is connected to a mounting base, and the positioning antenna 6 is mounted on the mounting base. Specifically, the data from the positioning antenna 6 and the compaction sensor can be sent to the data processor 5. After processing and calculation, the data processor 5 displays the results on the screen in real time, allowing the driver to observe the road surface compaction status in real time. The compaction sensor is essentially an acceleration sensor.

[0035] This embodiment integrates a compaction sensor and a positioning antenna 6 onto the road roller, allowing the roller to record its compaction path and monitor the number of compaction passes in real time. This ensures proper compaction and optimizes the construction process, reducing unnecessary movement and repetitive work, thus improving construction efficiency. Furthermore, the vibration damping device 7, composed of longitudinal and transverse damping components 71 and 72, effectively absorbs and disperses vibrations from uneven road surfaces, providing omnidirectional vibration damping for the positioning antenna 6. This protects the antenna from damage, reduces vibrations during roller operation, and extends its service life.

[0036] Please refer to Figure 2In this embodiment, the longitudinal damping component 71 includes a movable plate 711, multiple positioning posts 712, and multiple elastic elements 713. One end of each positioning post 712 is fixed to the cab 4, and the other end passes through the movable plate 711. Multiple elastic elements 713 are correspondingly sleeved on the positioning posts 712, and the elastic elements 713 are located between the bottom of the movable plate 711 and the cab 4. The lateral damping component 72 and the mounting base are both located on the top of the movable plate 711. Specifically, the movable plate 711 is a movable structure that is snapped onto the multiple positioning posts 712 and can move relative to the positioning posts 712. The mounting base and the lateral damping component 72 are both located on the movable plate 711 and can move synchronously with the movable plate 711. The movable plate 711 has positioning holes through which the positioning posts 712 pass, and the positioning posts 712 and the positioning holes are clearance-fitted.

[0037] The longitudinal damping component 71 can absorb and release vertical vibration energy from the ground. When the road roller travels on a bumpy road, the elastic element 713 can deform to provide cushioning, thereby effectively reducing the vibration experienced by the positioning antenna 6. The positioning post 712 can also serve as a guide mechanism for the movable plate 711, allowing the movable plate 711 to slide up and down only along the positioning post 712, which also facilitates the positioning and installation of the movable plate 711.

[0038] In this embodiment, the movable plate 711 is movable relative to the positioning post 712. An adjusting block 7121 is threadedly connected to the outer periphery of the positioning post 712. The adjusting block 7121 is located at the top of the movable plate 711 and abuts against it. Specifically, the positioning post 712 can be a threaded rod with external threads on its outer periphery, and the adjusting block 7121 can be a nut. The adjusting block 7121 is threadedly connected to the positioning post 712, meaning it can move relative to the positioning post 712, and is used to adjust the position of the movable plate 711 relative to the positioning post 712.

[0039] The adjusting block 7121 enables precise adjustment of the damping effect. The adjusting block 7121 can be easily rotated to change its position on the positioning post 712, thereby adjusting the pressure on the movable plate 711 and consequently the compression degree of the elastic element 713. This allows technicians to quickly and accurately adjust the damping performance according to specific needs, adapting to different working environments and operational requirements.

[0040] Please refer to Figure 3In this embodiment, there are multiple lateral vibration damping components 72, which are arranged at intervals around the outer periphery of the mounting base. Specifically, there can be four lateral vibration damping components 72, arranged at 90-degree intervals around the outer periphery of the mounting base. The arrangement of multiple lateral vibration damping components 72 provides multi-directional vibration damping protection for the positioning antenna 6, effectively absorbing vibrations from the ground or lateral vibrations generated when the road roller is running, reducing the load pressure on a single lateral vibration damping component 72. Together with the longitudinal vibration damping component 71, it can form all-round vibration damping protection for the positioning antenna 6.

[0041] Please refer to Figure 2 or Figure 3 In one embodiment, the lateral damping assembly 72 includes a fixed block 721 and a hydraulic damper 722, with both ends of the hydraulic damper 722 connected to the fixed block 721 and the mounting base, respectively. The two ends of the hydraulic damper 722 can be hinged to the fixed block 721 and the mounting base, or they can be fixedly connected.

[0042] As the core component of the lateral damping assembly 72, the hydraulic damper 722 possesses excellent damping and energy absorption capabilities. When the road roller travels on uneven ground or performs compaction operations, the hydraulic damper 722 can quickly respond and absorb vibrations and impacts from the ground. Furthermore, the hydraulic damper 722 is typically equipped with adjustable valves or throttling devices, allowing technicians to dynamically adjust its damping performance according to the specific construction environment and operational requirements.

[0043] Please refer to Figure 4 In another embodiment, the lateral damping assembly 72 includes a fixing block 721, a sleeve 723 disposed on the fixing block 721, a buffer member 725 disposed within the sleeve 723, and a push rod 724 disposed on the mounting base. The push rod 724 is movably inserted into the sleeve 723 and abuts against the buffer member 725. Similarly, the sleeve 723 can be hinged or fixedly connected to the fixing block 721, and the push rod 724 can be hinged or fixedly connected to the mounting base.

[0044] Specifically, when the road roller is subjected to vibration or impact, the mounting base and positioning antenna 6 will shake. When the mounting base shifts laterally, the top rod 724 will slide inside the sleeve 723 and achieve buffering and shock absorption under the action of the buffer 725, thereby preventing the positioning antenna 6 from being subjected to severe impact. Its structure is simple and effective, and it is also easy to install.

[0045] It should be noted that the elastic element 713 and the buffer element 725 in this embodiment are metal springs or elastic rubber. In this embodiment, a metal spring is preferred. Both metal springs and elastic rubber have high elasticity and good resilience. When subjected to vibration, they can respond quickly and absorb energy, and they can quickly return to their original shape after the external force disappears, thereby maintaining the stability and reliability of the shock absorption system. Furthermore, both metal springs and elastic rubber have high wear resistance and fatigue resistance, enabling them to support long-term operation.

[0046] Please refer to Figure 2 In this embodiment, the mounting base is provided with several reinforcing ribs located on the outer periphery of the positioning antenna 6. The reinforcing ribs on the outer periphery of the positioning antenna 6 strengthen the support for the antenna 6, reduce its own sway, and make the antenna more stable and reliable. Alternatively, a ring can be provided on the outer periphery of the positioning antenna 6 to fix it in place.

[0047] It should be noted that the bottom of the mounting base rests on the movable plate 711, and the bottom of the mounting base is provided with a wear-resistant layer. Since the mounting base is in contact with the movable plate 711, the road roller will cause frequent relative sliding between the mounting base and the movable plate 711 during operation. Therefore, the wear-resistant layer can effectively reduce the friction and wear between the mounting base and the movable plate 711, thereby improving the service life of the shock absorber 7.

[0048] In this embodiment, a protective cover 8 is detachably installed on the top outer side of the cab 4. The protective cover 8 covers the outside of the shock absorber 7, and the protective cover 8 is also provided with a through hole 81 for the positioning antenna 6 to pass through. The protective cover 8 can be fixed by bolts or clips, and it only needs to be placed on the outer periphery of the shock absorber 7 and the head of the positioning antenna 6 should protrude.

[0049] Because road rollers operate in harsh environments, often involving large amounts of sand and dust, the protective cover 8 effectively protects the shock absorber 7 from damage caused by these external elements, extending its service life and reducing malfunctions and maintenance costs due to environmental factors. Furthermore, the detachable design of the protective cover 8 makes maintenance and inspection of the shock absorber 7 much more convenient.
