Technical Field

[0001] This utility model relates to the field of vertical detection technology in road and bridge construction, and in particular to a vertical detection device for road and bridge construction. Background Technology

[0002] In the construction of roads and bridges, the verticality of structural components is an important indicator for evaluating construction quality and structural stability. Currently, traditional methods such as laser rangefinders, levels, plumb bobs, or string lines are commonly used on-site to check the verticality of components.

[0003] As shown in the reference case "A Verticality Detection Device for Road and Bridge Construction" (Announcement No. CN221898494U), by adjusting the position and angle of components such as the horizontal moving base, vertical support frame, and sliding frame, and by using a synchronous drive component to ensure the synchronous movement of the two sliding frames, accurate detection of verticality in road and bridge construction is achieved.

[0004] However, existing road and bridge inspection devices have problems such as large size, complicated inspection steps, time-consuming assembly, or inconvenience in carrying. They are especially difficult to deploy and inspect quickly and efficiently in high-altitude bridge operations, narrow working surfaces, or temporary construction sections. Utility Model Content

[0005] Therefore, it is necessary to address the problems of existing road and bridge inspection devices, such as large size, cumbersome inspection procedures, time-consuming assembly, or inconvenience in carrying, especially in high-altitude bridge operations, narrow working surfaces, or temporary construction sections, where efficient deployment and inspection cannot be completed quickly. This necessitates providing a vertical inspection device for road and bridge construction, comprising: a support with a storage slot on one side, and an elastic telescopic rod fixedly installed on the surface of the support, the elastic telescopic rod being located on one side of the storage slot; and a portable inspection mechanism, a telescopic portable inspection mechanism for quickly deploying the inspection device for portable inspection, disposed on one side of the support; wherein the portable inspection mechanism includes a movable plate disposed on one side of the storage slot, a detection component for bridge verticality inspection disposed on one side of the movable plate, and a positioning component disposed on another side of the movable plate.

[0006] The detection assembly includes an electronic level fixedly installed on one side of the movable plate. The electronic level is embedded in one side of the movable plate. A rotating ring is rotatably installed on the surface of the movable plate. An indicator rod is fixedly installed on the outer side of the rotating ring. A counterweight is fixedly connected to the other end of the indicator rod.

[0007] An angle sensor is fixedly installed on one side of the movable plate, and a contact plate is fixedly connected to the output end of the angle sensor. The outer side of the contact plate is in close contact with the outer side of the rotating ring.

[0008] The outer side of the contact plate is integrally connected with multiple protrusions, and the outer side of the rotating ring is provided with multiple contact grooves.

[0009] A placement slot is provided on one side of the movable plate, and the placement slot is located on the side of the indicator rod and the counterweight.

[0010] A fixing block is fixedly attached to one side of the placement slot, and the fixing block has a groove on one side of the placement slot that matches the shape of the counterweight.

[0011] The positioning component includes a guide tube fixedly installed on one side of the movable plate. A positioning block is provided on one side of the guide tube. The positioning block is located on one side of the storage groove and abuts against the support on one side. The positioning block is slidably connected to the surface of the movable plate. A piston rod is fixedly connected to the side of the positioning block near the guide tube.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] The following is combined Figures 1-5 This utility model describes a vertical detection device for road and bridge construction.

[0025] In one embodiment, a vertical detection device for road and bridge construction, such as Figure 1 As shown, the road and bridge construction vertical detection device of this embodiment includes: a support 100, a storage groove 200 is provided on one side of the support 100, and an elastic telescopic rod 110 is fixedly installed on the surface of the support 100, the elastic telescopic rod 110 is located on one side of the storage groove 200; a portable detection mechanism 300, a telescopic portable detection mechanism 300 for quickly unfolding the detection device for portable detection is provided on one side of the support 100; wherein, the portable detection mechanism 300 includes a movable plate 310 provided on one side of the storage groove 200, a detection component 320 for bridge verticality detection is provided on one side of the movable plate 310, and a positioning component 330 is also provided on one side of the movable plate 310.

[0026] In this embodiment, the movable plate 310 can be fixed inside the storage slot 200 by the elastic telescopic rod 110 during use. When testing is required, the movable plate 310 can be unfolded to a perpendicular angle with the support 100, that is, the testing component 320 can be quickly unfolded to a perpendicular angle, which makes it convenient for on-site personnel to directly measure the verticality of bridge components. This eliminates the tedious steps of traditional manual assembly of brackets or additional fixing tools, significantly improving testing efficiency and response speed. The positioning component 330 can provide reliable limiting support after the movable plate 310 is unfolded, preventing it from shifting its angle due to vibration or external force during the testing process, thus ensuring testing accuracy and data reliability.

[0027] It should be noted that existing vertical inspection devices for road and bridge construction include a support base for bearing the inspection elements, an inspection rod equipped with horizontal or vertical scales, an inspection sensor or mechanical measuring plate for measuring angles or verticality, and a reference alignment structure for auxiliary positioning. During use, these devices must ensure the stability of the inspection elements, the accuracy of vertical positioning, and the overall structural rigidity of the device to guarantee the accuracy of the verticality data for bridge components.

[0028] The detection component 320 is mounted on the movable plate 310, which can quickly measure the vertical state of the bridge construction after unfolding without affecting the detection accuracy. When not in use, it can be stored together with the movable plate 310, improving the overall portability. The positioning component 330 provides angle limit and structural stability support after the movable plate 310 is unfolded, ensuring that the movable plate 310 does not shake or misalign during the detection process, thereby ensuring that the stability and repeatability of the measurement results will not adversely affect the normal use of the detection device.

[0029] like Figure 2 , Figure 3 and Figure 4 As shown, the detection component 320 includes an electronic level 321 fixedly installed on one side of the movable plate 310. The electronic level 321 is embedded in one side of the movable plate 310. A rotating ring 322 is rotatably installed on the surface of the movable plate 310. An indicator rod 323 is fixedly installed on the outer side of the rotating ring 322. A counterweight 324 is fixedly connected to the other end of the indicator rod 323.

[0030] In this embodiment, the electronic level 321 is embedded in the movable plate 310, which can assist in positioning the movable plate 310 to a standard level state when it is unfolded, avoiding angular deviations caused by uneven ground or installation errors; the rotating ring 322, in conjunction with the rotating installation structure of the indicator rod 323, allows the indicator rod 323 to be guided by the counterweight 324 to be naturally vertical in a free state, forming a reference line, which effectively reflects the tilt state of the bridge template or vertical structure, and is easy to operate and intuitive to observe.

[0031] It should be noted that the electronic level 321 is a widely used digital angle measuring device in the prior art. It typically uses a capacitive tilt sensor or a MEMS inertial unit as the measurement core, calculates the real-time angle deviation through internal circuitry, and displays the current measurement value through a digital display module. It boasts advantages such as high accuracy, fast response, and ease of use. In this embodiment, the electronic level 321 is embedded in the side surface of the movable plate 310, and its installation position remains fixed to the movable plate 310, directly reflecting the angle change of the movable plate 310 relative to the horizontal plane. During use, after the user unfolds the movable plate 310, the electronic level 321 can read whether the movable plate 310 has reached a preset horizontal state, thus providing a standard reference for the subsequent gravity-driven downward-hanging indicator rod 323, ensuring the accuracy of vertical detection.

[0032] An angle sensor 325 is fixedly installed on one side of the movable plate 310. The output end of the angle sensor 325 is fixedly connected to a contact plate 326. The outer side of the contact plate 326 is in close contact with the outer side of the rotating ring 322.

[0033] In this embodiment, after the movable plate 310 is unfolded, the angle sensor 325 can sense the change in the rotation angle of the rotating ring 322 in real time. The contact plate 326 maintains an outer contact with the rotating ring 322 and can synchronously follow its rotation, forming a continuous angle acquisition and feedback path. The signal output by the angle sensor 325 can further determine the deflection angle of the indicator rod 323 relative to the movable plate 310, thereby assisting in determining the vertical deviation of the bridge structure or construction components, achieving a more intuitive and quantitative detection effect.

[0034] It should be noted that the angle sensor 325 is a precision sensing element that can monitor changes in rotation angle in real time. It typically adopts a resistive, magnetoresistive, or MEMS (Micro-Electro-Mechanical System) structure. It integrates a sensing element and a signal conversion circuit, which can convert the angular displacement change of the contact plate 326 during rotation into a corresponding electrical signal output. By analyzing the output of the angle sensor 325, the change in the angle between the indicator rod 323 and the movable plate 310 can be quantitatively obtained, thereby indirectly judging the deviation angle in the vertical direction of bridge construction and improving the accuracy and objectivity of the detection results.

[0035] The angle sensor 325 is an external structure and does not directly participate in the physical swing process of the indicator rod 323. Therefore, it will not interfere with its natural hanging state, nor will it affect the normal unfolding and storage of the movable plate 310.

[0036] Multiple protrusions are integrally connected to the outer side of the contact plate 326, and multiple contact grooves are opened on the outer side of the rotating ring 322.

[0037] In this embodiment, multiple protrusions engage with adjacent contact grooves to achieve precise linkage between the contact disk 326 and the rotating ring 322. When the rotating ring 322 rotates due to gravity under the action of the indicator rod 323 and the counterweight 324, the multiple contact grooves on its outer side will drive the multiple protrusions on the outer side of the contact disk 326 to deflect synchronously, causing the contact disk 326 to produce a corresponding angular displacement.

[0038] A placement slot 327 is provided on one side of the movable plate 310, and the placement slot 327 is located on the same side as the indicator rod 323 and the counterweight 324.

[0039] In this embodiment, when not in use, the indicator rod 323 and the counterweight 324 can be stored in the placement slot 327, making the movable plate 310 more compact and orderly when it is in a folded state, thus improving the portability of the device and the efficiency of on-site deployment.

[0040] A fixing block 328 is fixedly attached to one side of the placement slot 327. The fixing block 328 is located on one side of the placement slot 327 and has a groove that matches the shape of the counterweight block 324.

[0041] In this embodiment, after the indicator rod 323 and the counterweight 324 are placed into the placement groove 327, the fixing block 328 can be locked into the placement groove 327. The groove shape on the fixing block 328 is adapted to the shape of the counterweight 324, thereby realizing the fitting nesting and locking of the counterweight 324. This not only effectively prevents the counterweight 324 from sliding or falling off during transportation or shaking, but also simultaneously limits and fixes the indicator rod 323.

[0042] like Figure 2 , Figure 3 and Figure 5 As shown, the positioning component 330 includes a guide tube 332 fixedly installed on one side of the movable plate 310. A positioning block 331 is provided on one side of the guide tube 332. The positioning block 331 is located on one side of the storage groove 200, and one side of the positioning block 331 abuts against the support 100. The positioning block 331 is slidably connected to the surface of the movable plate 310. A piston rod 333 is fixedly connected to the side of the positioning block 331 near the guide tube 332. One end of the piston rod 333 extends into the interior of the guide tube 332 and is slidably connected to the interior of the guide tube 332.

[0043] In this embodiment, after the movable plate 310 is unfolded to a suitable angle, the positioning block 331 slides outward under the drive of the piston rod 333 and comes into close contact with the support 100, thereby forming a limiting stop structure. The positioning block 331 is slidably connected to the surface of the movable plate 310, which can achieve stable positioning of the movable plate 310 without affecting its normal unfolding and retraction.

[0044] A spring 334 is fixedly connected to one end of the piston rod 333 inside the guide tube 332, and the other end of the spring 334 is fixedly connected to the inner wall of the guide tube 332.

[0045] In this embodiment, the spring 334 is disposed inside the guide tube 332 to provide a constant elastic restoring force to the piston rod 333. When the detection device is not used and the movable plate 310 needs to be retracted to the storage slot 200, the elasticity of the spring 334 can be overcome by applying external force, so that the piston rod 333 retracts and the positioning block 331 retracts to the direction of the guide tube 332, providing space for the folding and storage of the movable plate 310.

[0046] Working principle: The on-site inspection personnel first position the support 100, then press down the elastic telescopic rod 110 to release its restriction on the movable plate 310, allowing the movable plate 310 to detach from the constraint of the storage groove 200. After pressing down, the operator unfolds the movable plate 310 along one side of the support 100, so that it forms an approximately perpendicular angle with the support 100. At this time, the electronic level 321 can be used to determine whether the movable plate 310 is at the standard horizontal reference. The positioning component 330 is then activated. The piston rod 333 pushes out the positioning block 331 under the action of the spring 334, so that it presses against the support 100 to form a stable support. Then, the indicator rod 323 hangs down naturally under the guidance of the counterweight 324, forming an intuitive vertical detection reference through the vertical angle between it and the movable plate 310. At the same time, the rotating ring 322 rotates due to the swing of the indicator rod 323, driving the meshing contact plate 326 to rotate synchronously. The angle sensor 325 outputs a real-time angle change signal accordingly, realizing a quantitative assessment of the deflection of the bridge component. After the detection is completed, the positioning block 331 can be pressed to retract it, and the indicator rod 323 and the counterweight 324 can be put into the placement slot 327 and locked by the fixing block 328, realizing the quick storage and portable restoration of the device.

[0047] It should be noted that the electronic level and angle sensor mentioned above are all devices with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the specific power supply method for the electronic level and angle sensor can be selected according to the situation, such as built-in power supply, which will not be elaborated here.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
