Description

Technical Field

[0001] This utility model relates to the field of engineering testing technology, specifically a vertical testing device for roads and bridges. Background Technology

[0002] In the construction, operation, and maintenance of roads and bridges, the verticality of bridge piers is one of the core indicators for measuring the stability and safety of the engineering structure. As a key load-bearing component of roads and bridges, any deviation in the verticality of bridge piers will not only directly affect the overall stress balance of the bridge and lead to uneven stress distribution, but may also cause serious safety hazards such as cracks, tilting, or even collapse under long-term use. At the same time, it will also significantly increase the cost and difficulty of later maintenance and reinforcement. Therefore, accurate and efficient vertical testing of bridge piers is a key link in ensuring the quality and operational safety of road and bridge projects.

[0003] However, current methods for detecting the verticality of road and bridge piers in the industry generally suffer from problems such as complex operation, low detection efficiency, unintuitive data presentation, and difficulty in judging results, making it difficult to meet the needs of efficient and accurate detection in actual engineering projects. For example, traditional detection methods often rely on manual measurement using professional equipment such as levels and theodolites. Such methods require highly skilled operators who need to undergo systematic training and master complex processes such as instrument calibration, angle measurement, and data calculation. The high operational threshold and low detection efficiency seriously affect the overall progress of road and bridge construction or maintenance projects.

[0004] To address these issues, we have provided a vertical inspection device for roads and bridges. Utility Model Content

[0005] 1) Technical problems to be solved

[0006] This utility model proposes a road and bridge verticality detection device. Through the cooperation of components such as a winding roller, steel wire, plumb box, first distance measuring device, second distance measuring device, and display terminal, it solves the problems of traditional road and bridge pier verticality detection, which is complicated to operate, has low detection efficiency, does not present data intuitively, and is difficult to judge the results.

[0007] (ii) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a vertical inspection device for roads and bridges, comprising an inspection box, wherein a winding roller is rotatably connected inside the inspection box, and a steel wire is wound around the outer end of the winding roller;

[0009] The end of the steel wire passes through the lower end of the detection box, and the end of the steel wire is connected to a drop box.

[0010] The drop box is connected to a first rangefinder, which uses a rangefinder laser to irradiate the surface of the bridge column.

[0011] A second rangefinder is connected to the upper end of the drop box, and the second rangefinder irradiates the lower surface of the detection box with a range-measuring laser.

[0012] A drive motor is provided at the outer end of the detection box, and the drive motor is connected to a winding roller.

[0013] The upper end of the testing box is connected to a display terminal, which contains a display screen.

[0014] Furthermore, a protective pad is connected to the side of the detection box, and the protective pad is attached to the surface of the bridge column.

[0015] Furthermore, a constraint tube is connected inside the testing box, and the steel wire passes through the constraint tube and exits the testing box. The upper end of the constraint tube is smoothly rounded.

[0016] Furthermore, both the detection box and the drop box are equipped with batteries, and the drop box is equipped with a signal transmitter, which transmits signals to the display terminal.

[0020] (iii) Beneficial effects:

[0021] Compared with existing technologies, this road and bridge vertical inspection device has the following advantages:

[0022] I. This road and bridge verticality detection device, equipped with a steel wire and a plumb bob, places the detection box against the surface of the bridge pier. Under the influence of gravity, the plumb bob keeps the steel wire vertical. A winding roller adjusts the height of the plumb bob by rotating to unwind and wind up the steel wire. A first and second distance measuring device measures the distance between the plumb bob and the surface of the bridge pier, as well as the lower surface of the detection box, respectively. The data is displayed on a terminal using an XY-axis coordinate system (when the bridge pier is vertical, the Y-axis value remains approximately constant and parallel to the X-axis; a deviation in the Y-axis value indicates that the bridge pier is not vertical). This intuitive data display accurately reflects the verticality of the bridge pier, allowing operators to quickly assess its verticality. It has a low operational threshold, significantly improves detection efficiency, provides intuitive data presentation, and makes result judgment more efficient.

[0023] Second, this road and bridge vertical detection device is equipped with a windproof cover, and the drop box rises and falls inside the windproof cover to avoid it from swinging due to external wind interference, thereby ensuring the accuracy of distance measurement. In addition, the windproof cover and the detection box are connected by magnetic attraction, which can be easily separated, thereby reducing the space occupied by the device and facilitating transportation and placement.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] like Figures 1-7 As shown, this utility model provides a technical solution: a vertical inspection device for road bridges, including an inspection box 1, a take-up roller 2 rotatably connected inside the inspection box 1, a drive motor 7 at the outer end of the inspection box 1, the drive motor 7 driving the take-up roller 2, the drive motor 7 driving the take-up roller 2 to rotate, a protective pad 9 connected to the side end of the inspection box 1, the protective pad 9 adhering to the surface of the bridge column, the protective pad 9 being made of soft rubber or other materials with a certain friction, when the inspection box 1 is against the bridge column, the protective pad 9, on the one hand, prevents the inspection box 1 from directly contacting the bridge column, preventing scratches and other damage to the surface of the bridge column, on the other hand, its friction allows the inspection box 1 to adhere more firmly to the bridge column, reducing the shaking of the inspection box 1 during the inspection process and ensuring the stability of the inspection.

[0035] A steel wire 3 is wound around the outer end of the take-up roller 2. The tail end of the steel wire 3 passes through the lower end of the detection box 1. A constraint tube 10 is connected inside the detection box 1. The steel wire 3 passes through the constraint tube 10 and exits the detection box 1. The upper end of the constraint tube 10 is smoothly set. The constraint tube 10 can guide the steel wire 3 to ensure that the steel wire 3 falls vertically. Its smooth upper end design can reduce the wear of the steel wire 3 when it passes through.

[0036] The tail end of the steel wire 3 is connected to a drop box 4. The side end of the drop box 4 is connected to a first distance measuring device 5. The first distance measuring device 5 illuminates the bridge column surface with a distance measuring laser to measure the distance between the drop box 4 and the bridge column surface. The upper end of the drop box 4 is connected to a second distance measuring device 6. The second distance measuring device 6 illuminates the lower surface of the detection box 1 with a distance measuring laser to measure the distance between the detection box 1 and the detection box 1.

[0037] The upper end of the detection box 1 is connected to a display terminal 8, which contains a display screen. Both the detection box 1 and the drop box 4 contain batteries. The drop box 4 contains a signal transmitter, which transmits signals to the display terminal 8. The display terminal 8 receives the distance measurement values ​​from the first rangefinder 5 and the second rangefinder 6. The display screen of the display terminal 8 displays the values ​​using an XY coordinate system. The X-axis represents the detection value of the second rangefinder 6, and the Y-axis represents the detection value of the first rangefinder 5. When the bridge column is vertical, regardless of how the X-axis data changes, the Y-axis value remains approximately constant (within the error range) and parallel to the X-axis. Therefore, if the Y-axis value deviates and is not parallel to the X-axis, it indicates that the bridge column is not vertical. Furthermore, if the Y-axis value is a straight line, its tilt angle can be calculated.

[0038] Handles 11 are connected to both sides of the testing box 1. The handles 11 are ergonomically designed for easy gripping by the operator. Control buttons 12 are connected to the outer ends of the handles 11. The control buttons 12 are used to control the forward and reverse rotation of the drive motor 7, thereby controlling the lifting and lowering of the drop box 4. A level measuring ruler 13 is connected to the side of the testing box 1. The level measuring ruler 13 works based on the principle of a bubble level. When the testing box 1 is against the surface of the bridge column, the operator can determine whether the testing box 1 is in a level state by observing the position of the bubble in the level measuring ruler 13.

[0039] The lower end of the testing box 1 is equipped with a windproof cover 14, and the drop box 4 is located inside the windproof cover 14 without contact between the two. The windproof cover 14 surrounds the drop box 4 inside, forming a relatively stable space, effectively blocking the wind from directly acting on the drop box 4, ensuring that the drop box 4 can measure stably during the testing process and improving the accuracy of the test data. The upper end of the windproof cover 14 is connected to an insert plate 15, and the lower end of the testing box 1 is connected to a connecting rail 16. The insert plate 15 is located inside the connecting rail 16. Magnetic blocks are correspondingly set on both, and the two are magnetically connected to each other, so as to facilitate the assembly and disassembly of the windproof cover 14 and the testing box 1.

[0040] Working principle: When in use, the operator first installs the windproof cover 14 on the lower end of the detection box 1 through the magnetic connection between the insert plate 15 and the connecting rail 16. Then, the operator holds the two handles 11 with both hands and places the detection box 1 against the surface of the bridge column, so that the protective pad 9 fits tightly against the bridge column. At the same time, the operator observes the level measuring ruler 13 and adjusts the position of the detection box 1 until the level measuring ruler 13 shows that the detection box 1 is in a horizontal state, laying the foundation for accurate detection.

[0041] The operator presses control button 12 to send a reverse signal to drive motor 7. Drive motor 7 drives take-up roller 2 to rotate, and take-up roller 2 gradually releases steel wire 3. The drop box 4 falls vertically along the bridge column under its own gravity. The first distance measuring device 5 on the side of drop box 4 continuously emits laser light onto the surface of the bridge column to measure the distance between drop box 4 and the surface of the bridge column. At the same time, the second distance measuring device 6 on the upper end of drop box 4 emits laser light onto the lower surface of detection box 1 to measure the distance between drop box 4 and the lower end of detection box 1. The two distance measuring devices transmit the measured data to the signal transmitter inside drop box 4 in real time. The signal transmitter sends the data to display terminal 8 through wireless communication.

[0042] After receiving the data, the display terminal 8 displays the data on the screen in the form of an XY axis coordinate system. As the drop box 4 descends, the X-axis value changes with the distance between the drop box 4 and the lower end of the detection box 1, while the Y-axis value reflects the distance between the drop box 4 and the surface of the bridge column. In this way, the operator can observe the changes in the data on the display screen in real time. (When the Y-axis value displayed on the screen is roughly consistent (within the error range) and parallel to the X-axis, it indicates that the bridge column is vertical. If the Y-axis value deviates significantly and is not parallel to the X-axis, it indicates that the bridge column is not vertical. If the Y-axis value forms a straight line, the display terminal 8 can calculate the tilt angle of the bridge column using the relationship between the changes in the X-axis and Y-axis values ​​according to relevant mathematical algorithms and display it on the screen to provide the operator with more detailed detection results.)

[0043] After the test is completed, the operator presses the control button 12 to send a signal to the drive motor 7. The drive motor 7 drives the take-up roller 2 to reverse, winding and retrieving the steel wire 3, and the drop box 4 rises back to the initial position.
