Description

Technical Field

[0001] The utility model relates to the technical field of vertical detection equipment, in particular to a vertical detection device for roads and bridges. Background Art

[0002] Road bridges are generally structures built to cross natural or artificial obstacles. They are erected on rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. Whether some of the main bodies of road bridges are vertical will affect the quality and safety of the buildings. Therefore, it is necessary to detect whether the road bridges are vertical during construction.

[0003] A Chinese patent with the announcement number CN219977417U discloses a road and bridge vertical detection device. By configuring a steel rope, a plumb bob, and a detection plate, the device allows the plumb bob to naturally droop and compare with the detection plate during use, thereby reading the verticality of the road and bridge. This allows a single person to quickly complete the detection. Furthermore, by configuring outriggers and rubber pads, the device allows the rubber pads to contact the ground during the detection process, providing shockproof and anti-slip protection for the box, thereby reducing detection errors and improving the detection accuracy of the device.

[0004] While the above solution supports the box through legs and rubber pads, the rubber base will wear out due to friction after prolonged use, causing the box to tilt when placed on a road or bridge, leading to deviations in detection results. Furthermore, the device itself lacks calibration, resulting in low accuracy. Therefore, we have developed a road and bridge verticality detection device to address these issues.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] like Figure 1-3 As shown, the utility model provides a technical solution: a road bridge vertical detection device, including a detection box 1, a limit assembly, a base plate 14 and a support assembly.

[0026] Glass plates 2 are inlaid on the four sides of the test box 1. The glass plates 2 are made of transparent material, which enables the inspector to directly observe the structure inside the test box 1. A plumb bob assembly is provided in the test box 1, and a bubble level 7 is installed on the upper surface of the test box 1. The bubble level 7 is an existing structure and can detect the parallelism of the test box 1 placed on the ground through the bubbles inside it.

[0027] The plumb bob assembly includes a square block 3 fixedly connected to the inner top wall of the detection box 1, and a detection plate 4 is fixedly connected to the four sides of the square block 3. Two groups of steel ropes 5 are fixedly connected to the inner top wall of the detection box 1, and the bottom end of each steel rope 5 is fixedly connected to a lead block 6. The outer surface of the detection plate 4 is designed with arc-shaped scale lines. The verticality of the bridge or road is detected by the position of the steel wire rope 5 on the scale lines on the detection plate 4.

[0028] The limit assembly is arranged in the detection box 1, and is used to keep the plumb bob assembly in a vertical state relative to the detection box 1. The limit assembly includes a movable groove 8 opened on the detection box 1 and a fixed seat 9 fixedly connected to the detection box 1. The fixed seat 9 is rotatably connected to a screw rod 10, and a movable block 11 is threadedly connected to the screw rod 10. One end of the movable block 11 passes through the movable groove 8 and is fixedly connected to a protective cover 12. The movable block 11 is slidably connected to the movable groove 8, and a protective cavity 13 adapted to the lead block 6 is opened on the protective cover 12.

[0029] When the device is moved, the screw rod 10 needs to be rotated to enable the moving block 11 to drive the protective cover 12 to move upward, and the lead block 6 is accommodated inside the protective cavity 13, so as to limit the position of the lead block 6.

[0030] The bottom surface of the base plate 14 is fixedly connected to the support leg 15, the upper surface of the base plate 14 is fixedly connected to the support column 16, the bottom surface of the detection box 1 is fixedly connected to the ball shaft rod 17, and the ball shaft rod 17 is rotatably connected to the top of the support column 16. The spherical bottom end of the ball shaft rod 17 rotates on the support column 16, so that the ball shaft rod 17 can swing in multiple directions and angles on the support column 16.

[0031] The support assembly is arranged on the base plate 14 and is used to support the bottom surface of the detection box 1 at multiple positions. The support assembly includes two groups of L brackets 18. The bottom end of the L bracket 18 is fixedly connected to the base plate 14. The L bracket 18 is threadedly connected to an adjusting bolt 19. The top end of the adjusting bolt 19 is fixedly connected to a hemispherical block 20, and the hemispherical block 20 is abutted against the bottom surface of the detection box 1.

[0032] When the test box 1 needs to be calibrated, the adjusting bolt 19 can be rotated and adjusted by observing the bubble level 7, so that the hemispherical block 20 lifts one end of the bottom surface of the test box 1, so that the bubbles of each bubble level 7 on the test box 1 are in the center position, ensuring the level of the test box 1 itself.
