Abstract
Description
Technical Field
[0001] This utility model belongs to the field of highway engineering testing technology, specifically relating to a highway engineering testing measuring ruler. Background Technology
[0002] Highway engineering inspection refers to the process of systematically assessing the quality and monitoring the safety of highway engineering projects during the design, construction, and operation stages through professional technical means. It covers a comprehensive review of material performance, structural strength, construction techniques, and functional requirements, aiming to ensure that the project meets design standards and safety requirements.
[0003] The angle of a highway is a crucial indicator for acceptance testing. One type of measuring ruler for highway engineering quality inspection, with publication number CN216898584U, solves the problems of traditional measuring rulers, which require manual hand-holding for measurement, leading to inaccuracies and wobbling, and are also inconvenient to use. Building upon this solution, another type of highway engineering inspection measuring ruler, with publication number CN219390933U, is improved, addressing the limitation of the measuring ruler in CN216898584U in terms of measurement angle. Both of these technical solutions only allow measurement at a fixed point. If multiple points need to be inspected on a highway, operators must measure at multiple locations, which is extremely time-consuming and labor-intensive. Utility Model Content
[0004] To address the inefficiency of existing technologies for multi-point or full-section highway inspections, this invention provides a highway engineering inspection measuring ruler. This ruler utilizes a transport trolley in conjunction with an angle sensor for rapid highway angle detection. The specific technical solution is as follows: A highway engineering inspection measuring ruler includes a measuring chassis and four transport wheels. The four transport wheels are respectively mounted on the lower wall of the measuring chassis. The measuring chassis is cross-shaped, and the four transport wheels are fixedly connected to the measuring chassis. An electronic measuring structure and a pushing structure are mounted on the upper wall of the measuring chassis. Four sets of correction support structures are mounted on the side walls of the measuring chassis. The electronic measuring structure includes a tilt sensor, a battery, and a signal transmitter. The tilt sensor, battery, and signal transmitter are all mounted on the upper wall of the measuring chassis.
[0005] Preferably, the pushing structure includes: a pushing bracket, a pushing universal joint, a pushing main tube, and a pushing sub-tube; the pushing bracket is mounted on the upper wall of the measuring chassis, the pushing universal joint is mounted on the upper wall of the pushing bracket, the pushing main tube is mounted on the upper wall of the pushing universal joint, and the pushing sub-tube is movably mounted inside the pushing main tube by means of threads.
[0006] Preferably, the four sets of calibration support structures include: a calibration support plate, a calibration screw, and a calibration support chassis; the calibration support plate is installed on the side wall of the measuring chassis, the calibration screw is movably installed inside the calibration support plate via a thread, and the calibration support chassis is movably installed on the lower wall of the calibration screw via a turntable.
[0007] Preferably, two bubble levels are mounted on the upper wall of the measuring chassis, and the two bubble levels are perpendicular to each other.

[0011] This utility model discloses a highway engineering inspection and measuring ruler. Compared with the prior art, the advantages are as follows: This highway engineering inspection and measuring ruler achieves automatic angle measurement by using a trolley carrying an inclination sensor. The trolley's support plate and wheels are fixedly connected, allowing the upper surface of the trolley to directly reflect the angle of the highway surface. This enables the inclination sensor to accurately collect data and quickly measure angles. Combined with wireless data transmission, the data can be centralized in a data center for convenient subsequent data processing. By having an operator drive the trolley along the highway to be inspected, the angle inspection of the entire highway can be completed, significantly improving measurement efficiency.

The present invention provides a technical solution: a highway engineering inspection and measuring ruler, comprising: a measuring chassis 1 and four transport wheels 2, the four transport wheels 2 being respectively installed on the lower wall of the measuring chassis 1, the measuring chassis 1 being cross-shaped, and the four transport wheels 2 being fixedly connected to the measuring chassis 1, an electronic measuring structure being installed on the upper wall of the measuring chassis 1, a pushing structure being installed on the upper wall of the measuring chassis 1, and four sets of correction support structures being installed on the side wall of the measuring chassis 1; the electronic measuring structure includes: an inclination sensor 3, a battery 4, and a signal transmitter 5; the inclination sensor 3 is installed on the upper wall of the measuring chassis 1, the battery 4 is installed on the upper wall of the measuring chassis 1, and the signal transmitter 5 is installed on the upper wall of the measuring chassis 1.
[0018] As a preferred embodiment, the pushing structure further includes: a pushing bracket 6, a pushing universal joint 7, a pushing main tube 8, and a pushing sub-tube 9; the pushing bracket 6 is mounted on the upper wall of the measuring chassis 1, the pushing universal joint 7 is mounted on the upper wall of the pushing bracket 6, the pushing main tube 8 is mounted on the upper wall of the pushing universal joint 7, and the pushing sub-tube 9 is threadedly mounted inside the pushing main tube 8.
[0019] As a preferred embodiment, the four sets of calibration support structures further include: calibration support plate 10, calibration screw 11, and calibration support chassis 12; calibration support plate 10 is installed on the side wall of measuring chassis 1, calibration screw 11 is installed inside calibration support plate 10 by means of thread, and calibration support chassis 12 is installed on the lower wall of calibration screw 11 by means of turntable.
[0020] As a preferred option, two bubble level rulers 13 are installed on the upper wall of the measuring chassis 1, and the two bubble level rulers 13 are perpendicular to each other.
[0021] As a preferred option, a push handle 14 is further installed on the upper wall of the push tube 9.
[0022] As a preferred option, a calibration handle 15 is further installed on the upper wall of the calibration screw 11.
[0023] As a preferred option, a counterweight 16 is further installed on the lower wall of the measuring chassis 1.
[0024] Working principle:
[0025] I. Preparations before use: The operator first charges the battery 4 using an external AC power source. When the battery 4 is fully charged, it can be used. The operator rotates the push tube 9 to adjust the relative length between the push tube 8 and the push tube 9, making the operation of this utility model more comfortable for the operator.
[0026] II. Calibration before use: The operator removes the connecting shaft of the universal joint 7 and places the four transport wheels 2 and the measuring chassis 1 on the road. The operator rotates the calibration handle 15 to drive the calibration screw 11 to rotate. Under the action of the thread, the calibration screw 11 moves downward inside the calibration support plate 10 until the calibration support chassis 12 contacts the ground, suspending the four transport wheels 2. The operator observes the bubble level 13 and ensures that both bubble levels 13 are horizontal. At this point, the measuring chassis 1 is horizontal. The operator then activates the tilt sensor 3 and initiates its calibration. At this point, the X and Y directions of the tilt sensor 3 are both zeroed, completing the calibration. The operator then rotates the calibration screw 11 using the calibration handle 15 to reset the calibration screw 11 until the four transport wheels 2 contact the road.
[0027] III. Highway Inclination Measurement: The operator holds the push handle 14 and pushes the measuring chassis 1 forward. Under the action of the counterweight 16, the four transport wheels 2 will fit tightly against the highway to be measured. Since the four transport wheels 2 are fixedly connected to the measuring chassis 1, the measuring chassis 1 can directly reflect the inclination of the highway surface. This means the inclination sensor 3 directly measures the inclination of the highway surface, and the data from the inclination sensor 3 is transmitted wirelessly to the data processing center via the signal transmitter 5 for further data analysis. The inclination sensor 3 collects data once per second, thus ensuring data accuracy. Furthermore, since the push tube 8 and the push bracket 6 can be connected via the push universal joint 7, manually pushing the push tube 8 will not change the angle of the measuring chassis 1, thus ensuring measurement accuracy to a certain extent.
