[0001] This utility model relates to the field of road surface testing technology, and in particular to a road surface settlement testing device. Background Technology

[0002] With the acceleration of urbanization and the increasing number of roads being built, road subsidence has become an increasingly prominent problem. Road subsidence not only affects the traffic capacity of roads, but also poses a threat to the safety of vehicles and pedestrians.

[0003] Timely and accurate detection of road settlement is of great significance. Traditional methods for road settlement detection mostly rely on manual, experience-based visual assessment, which is not only time-consuming and labor-intensive but also lacks accuracy. Therefore, a device capable of automatically, quickly, and accurately detecting road settlement is needed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing road settlement detection methods, which mostly rely on manual visual inspection based on experience, which is not only time-consuming and labor-intensive but also makes it difficult to guarantee measurement accuracy. Therefore, this invention proposes a road settlement detection device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A road surface settlement detection device includes a main board;

[0007] The main board has a sub-plate on its upper side, and a fixing block is fixed to the side end of the sub-plate. A measuring rod for measuring the settlement of the road surface slides inside the fixing block. A scale is provided on the side end of the measuring rod. A set of bonding components is provided inside the fixing block. The bonding components are used to drive the measuring rod to measure the settlement of the road surface.

[0008] A positioning component, disposed between a fixed block and a measuring rod, is used to position the measuring rod.

[0009] An adjustment assembly is provided between the main board and the sub-board, the adjustment assembly being used to adjust the length between the fixing block and the main board.

[0010] In one possible design, the positioning component includes a snap-fit ​​groove formed in the measuring rod, a third groove formed in the fixing block, a trapezoidal snap-fit ​​block that engages with the snap-fit ​​groove sliding in the third groove, a snap-fit ​​spring fixed to the side end of the trapezoidal snap-fit ​​block, and the snap-fit ​​spring fixed in the third groove.

[0011] In one possible design, the positioning assembly further includes a connecting rod fixed to the side end of the trapezoidal snap-fit ​​block, the connecting rod extending outward through the side end of the fixed block, a pull handle fixed to the side end of the connecting rod, and a snap-fit ​​spring sleeved on the surface of the connecting rod.

[0012] In one possible design, the bonding assembly includes a second groove formed within a fixed block, a measuring base plate for bonding with the settled road surface is slidably disposed within the second groove, the measuring rod is fixed to the side end of the measuring base plate, a bonding spring is fixed to the side end of the measuring base plate, the side end of the bonding spring is fixed within the second groove, and the bonding spring is sleeved on the surface of the measuring rod.

[0013] In one possible design, a limit block is fixed to the top of the measuring rod.

[0014] In one possible design, the adjustment assembly includes a first groove formed within the main board, a reciprocating lead screw rotatably disposed within the first groove, a slider fitted on the outer wall of the reciprocating lead screw to engage with a helical groove of the reciprocating lead screw, the slider sliding within the first groove, a side end of the reciprocating lead screw extending outward through a side end of the main board, a handle fixed to the side end of the reciprocating lead screw, and a sub-plate fixed to the top of the slider.

[0015] In this application, after the main board is placed on the unsettled ground, the handle is turned according to the distance between the unsettled ground and the settled ground. The handle drives the reciprocating screw to rotate, and the rotation of the reciprocating screw drives the slider to slide in the first groove. The slider drives the sub-plate and the fixing block to move, thereby adjusting the overall length of the device so that the main board can be placed on the unsettled ground and the fixing block is placed on the upper side of the settled ground.

[0016] By pulling the handle, the handle drives the trapezoidal locking block back into the third groove via the connecting rod. After the measuring rod loses its locking, the elasticity of the spring pushes the measuring base plate downward. The measuring base plate moves downward to fit the settled ground, and the measuring base plate drives the measuring rod downward. The amount of settlement of the settled ground can be accurately read by observing the scale on the measuring rod.

[0017] Beneficial effects: The road settlement detection device of this utility model, by setting a measuring rod and a scale, can realize accurate measurement of settled road surfaces, thereby improving the accuracy and efficiency of the measurement.

[0018] In this utility model, the road settlement detection device ensures the stability of the measuring rod by setting the positioning component, and prevents the measuring rod from shaking or shifting.

[0019] In this invention, the fitting component allows the measuring base plate to fit tightly against the settled road surface, further improving the accuracy of the measurement. Attached Figure Description

[0025] Example 1: Refer to Figures 1-3 A detection device includes a main board 1. The main board 1 serves as the foundational support component of the entire device, providing a stable mounting platform. A secondary plate 2 is located on the upper side of the main board 1, opposite to the main board 1, and is used to install and support other components. A fixing block 7 is fixed to the side end of the secondary plate 2, serving as the mounting and support component for a measuring rod 8, and is fixed to the secondary plate 2 by welding or bolting. The measuring rod 8 is slidably installed within the fixing block 7 and is used to measure the settlement of the road surface. A scale 9 is located on the side end of the measuring rod 8, displaying the extension length of the measuring rod 8, thereby indirectly reflecting the road surface settlement. A set of fitting components is provided within the fixing block 7, which drive the measuring rod 8 to measure the settled road surface, ensuring that the measuring rod 8 can tightly fit the settled road surface and improve measurement accuracy.

[0026] In addition, this device also includes a positioning component, which is located between the fixed block 7 and the measuring rod 8. This positioning component is used to position the measuring rod 8, ensuring that it remains stable and does not wobble when measurement is not required, thus guaranteeing measurement stability. An adjustment component is provided between the main board 1 and the sub-board 2. This adjustment component is used to adjust the length between the fixed block 7 and the main board 1, thereby adjusting the height of the entire detection device to adapt to road settlement detection requirements at different heights.

[0027] The positioning assembly includes a snap-fit ​​groove 14 formed within the measuring rod 8, extending along the length of the measuring rod 8. A third groove 16 is formed within the fixing block 7, and a trapezoidal snap-fit ​​block 15 is slidably mounted within the third groove 16. The trapezoidal snap-fit ​​block 15 engages with the snap-fit ​​groove 14, thereby positioning the measuring rod 8. A snap-fit ​​spring 17 is fixed to the side end of the trapezoidal snap-fit ​​block 15, and is fixed within the third groove 16. The snap-fit ​​spring 17 provides a restoring force to the trapezoidal snap-fit ​​block 15, allowing it to automatically snap into the snap-fit ​​groove 14 when no external force is applied.

[0028] To facilitate operation of the trapezoidal locking block 15, the positioning assembly also includes a connecting rod 18 fixed to the side end of the trapezoidal locking block 15. The connecting rod 18 extends outward through the side end of the fixing block 7, and a pull handle 19 is fixed to the side end of the connecting rod 18. By pulling the pull handle 19, the trapezoidal locking block 15 can slide within the third groove 16, thereby releasing the positioning of the measuring rod 8. A locking spring 17 is sleeved on the surface of the connecting rod 18 to prevent the connecting rod 18 from detaching from the fixing block 7 during sliding.

[0029] The bonding assembly includes a second groove 11 formed within the fixing block 7, in which a measuring base plate 12 is slidably mounted. The measuring base plate 12 is used to bond with the settled road surface. A measuring rod 8 is fixed to the side end of the measuring base plate 12. When the measuring base plate 12 is bonded to the settled road surface, the measuring rod 8 can extend or retract accordingly, thereby realizing the measurement of the settled road surface. A bonding spring 13 is fixed to the side end of the measuring base plate 12. The side end of the bonding spring 13 is fixed within the second groove 11 and is used to provide a restoring force for the measuring base plate 12, enabling it to bond tightly to the settled road surface. The bonding spring 13 is sleeved on the surface of the measuring rod 8 to prevent the measuring rod 8 from being disturbed during extension or retraction.

[0030] A limiting block 10 is fixed at the top of the measuring rod 8. The limiting block 10 is used to limit the extension length of the measuring rod 8 and prevent the measuring rod 8 from detaching from the fixing block 7 during the extension process.

[0031] This application can be used for road settlement detection, or for other fields applicable to this application.
