Description

Technical Field

[0001] This utility model relates to the field of road inspection technology, specifically to an integrated road deflection rapid detection device. Background Technology

[0002] Deflection refers to the vertical deformation of a roadbed or pavement under a specified load. The amount of rebound deflection 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. Generally, the larger the rebound deflection value, the greater the plastic deformation of the pavement structure, and the worse its fatigue resistance, making it difficult to withstand heavy traffic. Conversely, the pavement structure has good fatigue resistance and can withstand heavy traffic. Therefore, to know the effect of road deflection, it is generally necessary to use deflection testing equipment for testing.

[0003] Authorization announcement number CN219951629U discloses a municipal road deflection and bending detection device. This device mainly determines the overall stiffness and strength of the road structure by impacting a detection block onto the road surface and observing the vertical deformation state of the road surface. Then, a pressure sensor detects the deflection pressure value of the detection block on the road during the test. Therefore, it is beneficial to accurately detect the deflection value during road deflection and bending detection, thus ensuring the effectiveness of the road deflection and bending detection. In summary, existing rapid road deflection detection devices have the following problems:

[0004] 1. When using the drop hammer test method, it is usually necessary to manually rotate and lift the drop hammer, which is inconvenient in practice. At the same time, the test structure of the drop hammer has a certain weight, which increases the labor required for manual operation and reduces the test efficiency.

[0005] 2. When the device is moved, the set drop hammer is difficult to store and position, and may fall off naturally due to the vibration generated by the movement of the device, which may cause injury to the operator, increase the limitation and inconvenience of moving the device, and reduce the safety protection of the device. Utility Model Content

[0006] The purpose of this invention is to provide an integrated road deflection rapid detection device to address the shortcomings of existing technologies. It utilizes the splicing and automatic rotation functions of the rope reel to perform road deflection detection in conjunction with the overall structure of the detection device, thereby achieving automated lifting of the detection blocks. By integrating the protective structure and automatic winding structure with the detection device, the functionality and safety of the detection device are improved.

[0007] This utility model provides an integrated road deflection rapid detection device, including a bracket, an installation chamber installed on the inner side of the bracket, a horizontal calibration component on one side of the inner side of the bracket, and movable seats on both sides of the bottom of the bracket. The installation chamber is equipped with an automatic winding mechanism, a detection device and a limit locking component.

[0008] The automatic winding mechanism includes a rope reel, which is located at the top of the inner side of the installation chamber. A turntable is coaxially connected to one side of the rope reel, and a slot is opened on one side of the turntable. An electric push rod and a drive motor are respectively located on one side of the inner side of the installation chamber. The output end of the drive motor is connected to a rotating rod, and the output end of the electric push rod is connected to an installation plate. A sleeve is fitted inside the installation plate, and the sleeve slides on the outside of the rotating rod. A locking block is installed on the outside of the sleeve, and the locking block fits into the slot. A cable is wound on the rope reel.

[0009] The detection device includes a mounting plate connected to the end of a cable. A pressure sensor and a detection block are respectively provided on the bottom of the mounting plate, and a pressure display is provided on one side of the inner side of the bracket.

[0010] In the integrated road deflection rapid detection device described above, preferably, the slot is a herringbone structure opened on one side of the turntable, and the block is a herringbone structure installed on the outside of the sleeve, and the herringbone block and the slot fit together properly. The herringbone fitting structure improves the fixing effect of the structural splicing.

[0011] In the integrated road deflection rapid detection device described above, preferably, the rotating rod is a cross-shaped locking block structure, the inner side of the sleeve is provided with a cross-shaped guide groove, and the sleeve with the cross-shaped guide groove slides and engages with the outer side of the rotating rod. By utilizing the cooperation between the cross-shaped guide groove and the guide block, the sleeve can maintain its rotation function while moving horizontally on the outer side of the rotating rod.

[0012] In the integrated road deflection rapid detection device described above, preferably, a storage groove is provided at the middle position of the bottom of the installation chamber, and the detection block can be stored in the storage groove. A bearing seat is provided on the inner side of the installation plate, and two sets of positioning blocks are provided on the inner side of the installation chamber near the top of the installation plate. The positioning blocks are fitted and positioned with the installation plate, which facilitates the storage and protection of the detection device.

[0013] In the integrated road deflection rapid detection device described above, preferably, the horizontal calibration component includes a mounting shell, which is installed on one side of the inner side of the support. A threaded rod is rotatably mounted inside the mounting shell, and a suitable lifting block is fitted onto the threaded rod. The threaded rod is vertically positioned. A scale plate is vertically positioned on one side of the mounting shell, parallel to the threaded rod. The lifting block extends out of the mounting shell and is equipped with a telescopic rod. A handle is fitted onto one side of the support, with one end extending into the installation chamber. The upper end of the threaded rod also extends into the installation chamber. The threaded rod and the handle are connected by a meshing bevel gear set, facilitating the adjustment of the detection device's height, thereby enabling road deflection detection operations for different road surfaces.

[0014] The integrated road deflection rapid detection device described above is preferably characterized in that: the top of the lifting block is provided with a pointer, and the pointer cooperates with the scale plate. The cooperation between the pointer and the scale plate facilitates the adjustment of the specified height for road deflection detection.

[0015] In the integrated road deflection rapid detection device described above, preferably, the limiting and locking assembly includes guide rods, which are in two sets. The two guide rods are installed at the bottom of both sides inside the installation chamber. Sliding sleeves are fitted on the outer sides of the two guide rods. A limiting block is provided on the side of the two guide sleeves that are close to each other. A rotating rod is fitted on the bottom of one end of the installation chamber, and the rotating rod extends into the interior of the installation chamber and is equipped with a gear. A rack plate is provided on the top of one set of guide sleeves and the bottom of the other set of guide sleeves, and the rack plate meshes with the gear to increase the limiting and locking function of the device and prevent the installation plate from falling and causing safety hazards.

[0016] In the integrated road deflection rapid detection device described above, preferably, the two limiting blocks are U-shaped structures, and the two limiting blocks are opposite to and locked onto the horizontal surfaces of the mounting plate, thereby improving the limiting effect of the limiting blocks on the mounting plate.

[0017] The integrated road deflection rapid detection device proposed in this utility model has at least the following beneficial effects:

[0018] 1. Through the structural coordination of the automatic winding mechanism, a turntable and a slot for locking and splicing are easily connected to the rotating shaft of the rope winding wheel. According to the usage requirements, the horizontal adjustment of the mounting plate automatically drives the sleeve structure to slide, causing the locking block on the outside of the sleeve to engage and position with the slot, thereby completing the splicing and automatic rotation function of the rope winding wheel. When the locking block disengages from the locking surface with the slot, it can fall vertically under its own weight, so as to cooperate with the overall structure of the detection device to carry out the road deflection detection work. This realizes the automated lifting operation of the detection block, eliminating the dangers and inconveniences of existing manual operation and improving detection efficiency.

[0019] 2. Through the structural cooperation of the limiting and locking components, it is easy to set up a storage slot on the inside of the installation chamber for storing the detection device structure. When the device moves, the detection device is completely hidden. By using the displacement adjustment of the two sets of guide sleeves and limiting blocks, the limiting blocks are made to lock the side of the installation plate, so as to lock and position the installation plate structure, preventing the detection block from loosening and falling naturally. This integrates the protective structure and the automatic winding structure with the detection equipment, increasing the functionality and safety protection of the structure.

[0020] The cross-shaped guide structure of the rotating rod and sleeve causes the electric push rod to drive the sleeve, which is movably set inside the mounting plate, to move horizontally outside the rotating rod. This causes the sleeve to drive the herringbone-shaped locking block into the slot, thus connecting the sleeve with the turntable structure. At the same time, the drive motor and rotating rod output rotational force so that the rotating rod, sleeve, and the assembled turntable and slot rotate synchronously when the drive motor starts. This causes the turntable to drive the rope winding wheel connected to the shaft to rotate, realizing the automatic lifting and lowering function of the cable and detection device structure. This eliminates the labor required for existing manual operation. After the detection device structure is lifted, the locking block and slot connection structure is eliminated, and the detection block falls to the ground under gravity, working in conjunction with the pressure sensor to detect road deflection.

[0029] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0030] Embodiment 1 of this utility model: as follows Figures 1-7 As shown, it includes a bracket 1, an installation chamber 2 installed on the inner side of the bracket 1, a horizontal calibration component 3 on one side of the inner side of the bracket 1, and movable seats 4 on both sides of the bottom of the bracket 1. The installation chamber 2 is equipped with an automatic winding mechanism 5, a detection device 6 and a limit locking component 7.

[0031] The automatic winding mechanism 5 includes a rope winding wheel 51, which is located on the top of the inner side of the installation chamber 2. A turntable 52 is coaxially connected to one side of the rope winding wheel 51, and a slot 53 is opened on one side of the turntable 52. An electric push rod 54 and a drive motor 55 are respectively provided on one side inside the installation chamber 2.

[0032] The output end of the drive motor 55 is connected to a rotating rod 56, and the output end of the electric push rod 54 is connected to a mounting plate 57. A sleeve 58 is fitted inside the mounting plate 57, and the sleeve 58 slides on the outside of the rotating rod 56. A locking block 59 is installed on the outside of the sleeve 58, and the locking block 59 is properly engaged with the locking groove 53. The winding wheel 51 includes a cable. One end of the mounting chamber 2 is provided with an opening, and an observation window is provided on one side of the opening. Multiple sets of levers are provided on the outside of the turntable 52, and the levers partially extend outside the opening, making it easy to manually rotate the turntable 52 through the levers so that the turntable 52 can quickly be calibrated and engaged with the locking block on one side of the mounting plate 57, thereby increasing the auxiliary calibration function of the structural splicing engagement.

[0033] The detection device 6 includes a mounting plate 61, which is connected to the end of the cable. A pressure sensor 62 and a detection block 63 are respectively provided on the bottom of the mounting plate 61, and a pressure display is provided on one side of the inner side of the bracket 1.

[0034] The slot 53 is a herringbone structure on one side of the turntable 52, and the locking block 59 is a herringbone structure installed on the outside of the sleeve 58. The herringbone locking block 59 and the slot 53 fit together, and the herringbone locking structure improves the fixing effect of the structural splicing.

[0035] The rotating rod 56 has a cross-shaped locking block structure. The inner side of the sleeve 58 is provided with a cross-shaped guide groove, and the sleeve 58 with the cross-shaped guide groove slides and engages with the outer side of the rotating rod 56. By utilizing the cooperation between the cross-shaped guide groove and the guide block, the sleeve 58 can maintain its rotation function while moving horizontally on the outer side of the rotating rod 56.

[0036] A storage slot is provided at the middle of the bottom of the installation chamber 2, and the detection block 63 can be stored in the storage slot. The inner side of the installation plate 57 is provided with a bearing seat, and the sleeve 58 is fitted inside the bearing seat. Two sets of positioning blocks 8 are provided on the inner side of the installation chamber 2 near the top of the installation plate 61, and the positioning blocks 8 are fitted and positioned with the installation plate 61. This means that when the detection device 6 is stored in the storage slot, the installation plate 61 and the positioning blocks 8 are fitted and positioned, which facilitates the storage and protection of the detection device 6.

[0037] The horizontal calibration component 3 includes a mounting shell 31, which is installed on one side of the inner side of the bracket 1. A threaded rod 32 is rotatably mounted on the bottom of the interior of the mounting shell 31, and a threaded lifting block 36 is fitted onto the outer side of the threaded rod 32. The threaded rod 32 is vertically positioned (here, vertical means perpendicular to the horizontal plane). A scale plate 33 is provided on one side of the mounting shell 31, and the scale plate 33 is parallel to the threaded rod 32. The lifting block 36 extends out of the interior of the mounting shell 31 and is fixedly connected to a telescopic rod 37. The mounting shell 31 has openings along the length of the threaded rod 32. A clearance groove is provided to avoid the lifting block 36 so that the lifting block 36 can move along the threaded rod 32 when the threaded rod 32 rotates. A handle 34 is rotatably provided on one side of the bracket 1, and one end of the handle 34 extends into the interior of the mounting chamber 2. The upper end of the threaded rod 32 also extends into the mounting chamber 2. The threaded rod 32 and the handle 34 are connected by a meshing bevel gear set 35. Specifically, one of the two bevel gears of the bevel gear set 35 is fixedly sleeved on the upper end of the threaded rod, and the other bevel gear is fixedly installed on the end of the handle 34 located in the mounting chamber 2. Figure 5 As shown, this setup facilitates the adjustment of the height of the detection device 6, thereby enabling the detection of road deflection based on different road surfaces.

[0038] The top of the lifting block 36 is equipped with a pointer, which is matched with the scale plate 33. The matching of the pointer and the scale plate 33 makes it easy to adjust the specified height for road deflection detection.

[0039] The limiting and locking assembly 7 includes guide rods 71, which are in two sets. The two guide rods 71 ​​are installed at the bottom of both sides inside the installation chamber 2. The outer sides of the two guide rods 71 ​​are fitted with slidingly fitted guide sleeves 72. A limiting block 74 is provided on the side of the two guide sleeves 72 that are close to each other. A rotating rod is fitted at the bottom of one end of the installation chamber 2, and the rotating rod extends into the interior of the installation chamber 2 and is equipped with a gear 75. A rack plate 73 is provided at the top of one set of guide sleeves 72 and the bottom of the other set of guide sleeves 72. The rack plate 73 meshes with the gear 75 to increase the limiting and locking function of the device and prevent the installation plate 61 from falling and causing safety hazards.

[0040] The two limiting blocks 74 have a U-shaped structure. The two limiting blocks 74 are opposite to and locked onto the horizontal surfaces of the mounting plate 61, which improves the limiting effect of the limiting blocks 74 on the contact and locking of the mounting plate 61.

[0041] When conducting road deflection testing, the testing device 6 is connected to the automatic winding mechanism 5. In actual operation, the electric push rod 54 is activated to drive the mounting plate 57 and the sleeve 58 to slide inside the rotating rod 56. Under the guidance of the cross-shaped structure, the mounting plate 57 drives the sleeve 58 and the locking block 59 to engage in the slot 53 on the side of the turntable 52. The locking block 59 engages and is fixed with the slot 53, allowing the rotating structure of the sleeve 58 to connect with the turntable 52. At this time, the drive motor 55 can be activated to drive the rotating rod 56 and the sleeve 58 to rotate inside the mounting plate 57. The sleeve 58 drives the interconnected turntable 52 and the winding wheel 51 to rotate, which in turn automatically winds the cable on the outside of the winding wheel 51 and raises the testing device 6 to prepare for road deflection testing.

[0042] When the structure of the detection device 6 is raised, the engagement of the locking block 59 and the locking slot 53 can be canceled by canceling the start of the electric push rod 54. When the turntable 52 is not connected to the sleeve 58, it can fall naturally under the gravity of the detection block 63 so that it can hit the bottom surface to observe the vertical deformation state of the road surface, judge the road deflection and the overall structural strength of the road surface, and sense and display the pressure value detected by the detection block 63 through the pressure sensor 62 in conjunction with the pressure display, thereby realizing the rapid detection of road deflection.

[0043] like Figures 1-5As shown, the installation chamber 2 provides safety protection for the detection device 6. When the detection device 6 is placed in the storage slot inside the installation chamber 2, the rotating rod on the surface of the installation chamber 2 can be rotated to drive the gear 75 to rotate. This causes the gear 75 to synchronously drive the two sets of rack plates 73 and guide sleeves 72 to move towards each other under the guidance of the guide rod 71. This allows the guide sleeves 72 to drive the limiting block 74 to lock the horizontally opposite sides of the installation plate 61, thereby locking the installation plate 61 in place and preventing the overall structure of the detection device 6 from falling naturally, thus increasing the functionality and safety protection of the structure.

[0044] Rotating the handle 34 engages the bevel gear set 35, causing it to rotate the threaded rod 32. This rotation of the threaded rod 32 then raises and lowers the lifting block 36 along the end face of the scale plate 33. The lifting block 36 also moves the telescopic rod 37 synchronously. This allows the lifting block 36 to engage with the pointer on the scale plate 33, facilitating easy adjustment by the operator to the specified drop-weight test height. The telescopic rod 37's extension and retraction are matched to the lifting height of the test block 63 for calibration. This structure allows the operator to visually inspect the test block 63 at the specified height, enhancing the auxiliary functions of the structural inspection operation and improving the equipment's functionality and accuracy in detecting deflection on different road surfaces.
