Description

Technical Field

[0001] This utility model relates to the field of measurement and testing technology for irregular road surfaces, and in particular, to a cycling-type road testing device. Background Technology

[0002] Road inspection is a crucial step in ensuring road safety and performance. Since road surfaces are irregular, the measurement and inspection of these irregular surfaces involves assessing aspects such as road smoothness, surface condition, structural integrity, and performance.

[0003] With technological advancements, the detection technology for irregular road surfaces has gradually transitioned from traditional manual inspection to automated and intelligent inspection. However, to ensure the accuracy of the inspection and confirm the true condition of the road, providing accurate information for subsequent road construction and road safety, it is common practice to manually assess road surface issues on the sections inspected by the vehicle. This process is inefficient and labor-intensive. Furthermore, the installation and removal of inspection instruments on the vehicle are typically cumbersome, hindering subsequent maintenance and replacement. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a bicycle-type road detection device.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A rideable road inspection device for detecting the unevenness of irregular road surfaces includes: a vehicle body, including a frame, the frame having a mounting surface with a downward-facing mounting groove; an instrument for detecting the unevenness of irregular road surfaces, embedded in the mounting groove, the outer wall of the instrument's housing having a positioning slot, the top of the positioning slot having a vertical limiting wall, and the inner end of the positioning slot having a pre-tightening wall that converges inward from top to bottom; a top column having a positioning state and a dismounting state; in the positioning state, the top column is engaged in the positioning slot and abuts against the pre-tightening wall; in the dismounting state, the top column avoids the downward movement path of the instrument withdrawing from the mounting groove, and the top column moves laterally through the side wall of the mounting groove to achieve switching between the positioning state and the dismounting state; and an elastic element for applying an elastic force to the top column moving from the dismounting state to the positioning state.

[0007] Furthermore, the side wall of the mounting groove is provided with a perforation, the bottom of the perforation is provided with a strip-shaped notch, the top column is laterally movable through the perforation, the top column is connected to a toggle column, the toggle column is inserted through the strip-shaped notch and can move laterally along the strip-shaped notch, and the lower end of the toggle column extends out of the strip-shaped notch to protrude from the mounting surface.

[0008] Furthermore, the perforation includes a first threaded hole section, a guide sleeve is installed at the first threaded hole section, the guide sleeve has a guide hole in the middle, and a guide post is provided on the side of the top post away from the detector, which is inserted into the guide hole, and the guide post moves laterally along the guide hole.

[0009] Furthermore, the diameter of the top post is larger than that of the guide post, and the elastic element is a compression spring sleeved on the guide post, with the compression spring located between the guide sleeve and the top post.

[0010] Furthermore, the perforation includes a second threaded hole section located outside the first threaded hole section, the diameter of the second threaded hole section being larger than that of the first threaded hole section, and a hole cover is threadedly connected to the second threaded hole section.

[0011] Furthermore, the outer side of the guide sleeve is provided with a polygonal screwing protrusion.

[0014] Furthermore, the mounting groove is embedded with a sealing frame that is clamped between the detector housing and the side wall of the mounting groove.

[0015] Furthermore, the sealing frame is provided with a clearance opening aligned with the positioning slot.

[0016] This utility model has the following beneficial effects:

[0017] Featuring a ride-on design, inspectors can directly ride on the equipment while the detector performs real-time road inspections. The detector can measure irregular road surfaces to evaluate road smoothness and structural integrity. Compared to traditional manual walking inspections, this method allows for simultaneous instrument inspection and human observation and judgment, increasing inspection speed, reducing labor costs, and eliminating the need for manual re-inspection. The mounting surface and slots on the frame, along with positioning slots on the detector housing, allow for quick insertion and fixation in the mounting slots via a top post. The top post abuts against a pre-tightening wall to pre-tighten the detector, giving it an upward tendency to move and eliminating installation gaps. A vertical limiting wall prevents the top post from disengaging from the positioning slot along the pre-tightening wall, improving installation stability.

[0038] Please refer to Figure 1 , Figure 2 and Figure 3 The present invention provides a preferred embodiment of a cycling road inspection device for detecting the unevenness of irregular road surfaces, comprising a vehicle body 100, an inspection instrument 200, a top post 300, and an elastic element 400.

[0039] The vehicle body 100 includes a frame 110, which has a mounting surface 120 and a downward-facing mounting groove 130. A detector 200 is used to detect the smoothness of irregular road surfaces. The detector 200 is embedded in the mounting groove 130. The outer wall of the detector 200's housing has a positioning slot 210, a vertical limiting wall 211 at the top of the positioning slot 210, and a pre-tightening wall 212 at the inner end of the positioning slot 210. The pre-tightening wall 212 is designed to converge inwards from top to bottom, with "inwards" referring to the direction towards the mounting groove 130. The top post 300 has a positioning state and a disassembly state. In the positioning state, the top post 300 is engaged in the positioning slot 210 and abuts against the pre-tightening wall 212. In the disassembly state, the top post 300 avoids the downward movement path of the detector 200 as it is pulled out of the mounting groove 130, thus allowing the detector 200 to be disassembled smoothly without interfering with its removal. The top post 300 is laterally movable through the side wall of the mounting groove 130 to achieve switching between the positioning state and the disassembly state. The elastic element 400 is used to apply an elastic force to the top post 300 to move from the disassembly state to the positioning state, thereby giving the top post 300 a force to maintain the positioning state, so that it can maintain the positioning state when it is not subjected to a large external force.

[0040] This utility model provides a preferred embodiment of a ride-on road inspection device. The device features a ride-on design, allowing inspectors to ride directly on the equipment for real-time road inspection. Compared to traditional manual walking inspection, this method allows for simultaneous instrument inspection and manual observation and judgment, eliminating the need for re-inspection and increasing inspection speed while reducing labor costs. By providing a mounting surface 120 and mounting groove 130 on the frame 110, and a positioning slot 210 on the housing of the detector 200, the detector can be quickly embedded and fixed in the mounting groove 130 by a top post 300. The top post 300 abuts against the pre-tightening wall 212 to achieve pre-tightening of the detector 200, giving it an upward tendency to move and eliminating installation gaps. The vertical limiting wall 211 prevents the top post 300 from disengaging from the positioning slot 210 along the pre-tightening wall 212, improving the stability of the detector 200 installation. The design of the top post 300 allows for quick switching between positioning and disassembly states, enabling the fixing and disassembly of the detector 200 without complex operations. The elastic element 400 provides elastic force to the top column 300, making the detector 200 more stable in the positioning state and easy to operate when disassembly is required. This simplifies the maintenance and replacement process of the detection equipment and reduces maintenance costs.

[0041] Specifically, the vehicle body 100 can be electrically driven to reduce the rider's workload. A battery and drive motor can be installed inside the frame 110. The output shaft of the drive motor is connected to the wheel drive, specifically through a chain and sprockets. Of course, the vehicle body 100 can still retain pedals for pedal-driven operation, allowing continued use when the battery is low. When using electric drive, to ensure the long-term operation of the detector 200, such as... Figure 8 and Figure 9 As shown, the inner end of the mounting slot 130 is provided with a socket 170, and the top of the detector 200 is provided with a plug 230 adapted to the socket 170. The socket 170 is connected to the battery to obtain power for charging. Of course, the detector 200 can also be equipped with a built-in battery, so that it can be used when the battery on the frame 110 is depleted. In addition, the detector 200 can be a combination of one or more of the following: an infrared rangefinder, a laser scanner, and a panoramic camera, which can be selected as needed.

[0042] Reference Figure 4 , Figure 5 and Figure 6 In some embodiments of this utility model, the side wall of the mounting groove 130 is provided with a through hole 131, and the bottom of the through hole 131 is provided with a strip-shaped notch 132. The top post 300 is laterally movable through the through hole 131. The top post 300 is connected to a toggle post 310, which is inserted through the strip-shaped notch 132 and can move laterally along the strip-shaped notch 132. The lower end of the toggle post 310 extends out of the strip-shaped notch 132 to protrude from the mounting surface 120, thereby facilitating disassembly. During disassembly, the lower end of the toggle post 310 is manually operated to switch the top post 300 to the disassembly state, thereby facilitating the disassembly of the detector 200. It can be understood that the end of the strip-shaped notch 132 facing away from the mounting groove 130 is provided with an opening to facilitate the insertion of the toggle post 310 into the strip-shaped notch 132 during installation.

[0043] Reference Figures 2 to 7 In a further embodiment of this utility model, the through hole 131 includes a first threaded hole section 133, and a guide sleeve 140 is installed at the first threaded hole section 133. The guide sleeve 140 has an external thread on its outer periphery to be threadedly connected to the first threaded hole section 133, so as to realize detachable installation. The guide sleeve 140 has a guide hole 141 in the middle, and the top column 300 has a guide post 320 inserted into the guide hole 141 on the side opposite to the detector 200. The guide post 320 moves laterally along the guide hole 141, thereby improving the guidance for the movement of the top column 300.

[0044] Reference Figures 4 to 6In a further embodiment of this utility model, the diameter of the top post 300 is larger than that of the guide post 320, and the elastic element 400 is a compression spring sleeved on the guide post 320. The compression spring is located between the guide sleeve 140 and the top post 300, thereby achieving stable installation of the compression spring. The guide sleeve 140 and the top post 300 provide abutment positions for the two ends of the compression spring, so that the elastic force can be applied to the top post 300.

[0045] Reference Figure 2 In a further embodiment of this utility model, the through hole 131 includes a second threaded hole section 134 located outside the first threaded hole section 133. The outside refers to the side facing away from the mounting groove 130. The diameter of the second threaded hole section 134 is larger than that of the first threaded hole section 133 to facilitate processing and installation of the guide sleeve 140. A hole cover 150 is threadedly connected to the second threaded hole section 134 to cover the through hole 131 and reduce the entry of impurities that may affect the movement of the component.

[0046] Reference Figure 7 In a further embodiment of this utility model, a polygonal screwing protrusion 142 is provided on the outer side of the guide sleeve 140, thereby facilitating the screwing of the guide sleeve 140 by a tool.

[0047] Reference Figure 6 and Figure 8 In a further embodiment of this utility model, the side wall of the strip-shaped notch 132 is provided with a locking groove 135. The actuating column 310 on the top column 300 in the disassembled state can be rotated and locked into the locking groove 135 so that the top column 300 is kept in the disassembled state. Thus, when disassembling, the top column 300 can be moved to the disassembled state, and the actuating column 310 can be rotated and locked into the locking groove 135. Then, the hand can be released to disassemble the detector 200.

[0048] Understandably, in order to achieve multi-position limiting of the detector 200, two sets of positioning slots 210, perforations 131, top posts 300 and elastic elements 400 are symmetrically provided.

[0049] Reference Figure 6 and Figure 8 In a further embodiment of this utility model, a limiting protrusion 136 is provided on the side wall of the positioning groove 135 near the detector 200 and near the edge of the strip notch 132, thereby limiting the actuating post 310 that is inserted into the positioning groove 135, so that the actuating post 310 inserted into the positioning groove 135 does not easily disengage from the positioning groove 135. The actuating post 310 inserted into the positioning groove 135 will be in contact with the side wall of the positioning groove 135 near the detector 200 due to the force of the compression spring, and then the limiting protrusion 136 will limit it, so that it is stable in the positioning groove 135. When it is necessary for the actuating post 310 to disengage from the positioning groove 135, the actuating post 310 can be moved away from the mounting groove 130 to be misaligned with the limiting protrusion 136 and then rotated to disengage from the positioning groove 135.

[0050] Reference Figure 6 and Figure 8 In some embodiments of this utility model, the bottom of the housing of the detector 200 is provided with an outwardly expanding limiting flange 220. The contour of the limiting flange 220 is larger than that of the mounting groove 130. The limiting flange 220 limits the depth of the detector 200 inserted into the mounting groove 130 and facilitates the operation of the detector 200 when disassembling.

[0051] Reference Figures 6 to 8 In some embodiments of this utility model, the mounting groove 130 is embedded with a sealing frame 160 that is clamped between the housing of the detector 200 and the side wall of the mounting groove 130, thereby improving the sealing performance and reducing the installation gap.

[0052] Reference Figures 6 to 8 In some embodiments of this utility model, the sealing frame 160 is provided with an avoidance opening 161 aligned with the positioning slot 210, thereby avoiding structural interference. The sealing frame 160 may be made of rubber material, which has good elastic deformation capability.

[0053] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
