Description

Technical Field

[0001] The utility model belongs to the technical field of road maintenance, and more specifically, relates to a road defect detection device. Background Art

[0002] Road maintenance and inspection are an essential part of road safety. Road surface defect detection generally uses road surface inspection equipment equipped with an ultrasonic detector to scan the road surface back and forth for internal defect detection. The size of the inspection equipment depends on the width range of the ultrasonic detector probe. The staff moves back and forth with the inspection equipment to scan the road surface, but the probe detection width is limited and cannot accurately scan the road surface in all directions. The number of back and forth scans by the staff needs to be increased, and the working hours are longer.

[0003] Therefore, in view of this, the existing structure and defects are studied and improved, and a road defect detection device is provided to achieve a more practical and valuable purpose. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a road defect detection device to solve the problem that the probe detection width is limited, the road surface cannot be accurately scanned in all directions, and the number of times the staff needs to scan back and forth is increased, resulting in longer working hours.

[0005] The purpose and effect of the road defect detection device of the utility model are achieved by the following specific technical means:

[0006] A road defect detection device includes a detection box, the bottom of which is hollowed out, and a top frame is provided on the top. A display cover is hinged on the top frame for installing a display screen. A mounting frame is provided in the detection box, and a mounting groove for clamping a probe is provided at the bottom of the mounting frame. Notches running through the bottom are provided on both sides of the detection box, and mounting columns are provided in the notches. The top of the mounting column is rotatably connected to the detection box, and an electric telescopic rod is provided at the bottom of the mounting column. The bottom output end of the electric telescopic rod is connected to a supporting foot, and a static gear is sleeved on the mounting column. A motor is provided on the side wall of the detection box, and the output shaft of the motor is connected to a moving gear meshing with the static gear. A roller is provided at the bottom of the inner wall of the detection box.

[0007] Furthermore, a winding wheel is provided in the detection box, and shafts at both ends of the winding wheel are passed through the two side walls of the detection box.

[0008] Furthermore, the support leg is rectangular, with one end extending to the center of the bottom of the detection box and the other end extending symmetrically outside the detection box.

[0009] Furthermore, a limiting protrusion is provided on the supporting foot, and after the electric telescopic rod is extended so that the supporting foot is supported on the ground, the limiting protrusion can still abut against the inner wall of the detection box.

[0010] Furthermore, a traction ring is provided at the rear end of the detection box.

[0011] Furthermore, a fixing frame is provided on the back of the display cover, and the fixing frame is hinged with a supporting plate.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] Through the electric telescopic rods in the gaps on both sides of the detection box, after a row of road surface inspections is completed, the electric telescopic rods extend the support legs, causing the support legs to lift the detection box. The motor drives the dynamic gear to rotate, and the static gear engaged with it can make the detection box rotate around the mounting column. After rotating 180 degrees, the electric telescopic rods retract and the rollers return to the road surface again, realizing automatic steering of the detection box while aligning it with the previously tested row of road surfaces, reducing omissions in radar detection and the occurrence of repeated road surface scanning.

[0022] Example:

[0023] As attached Figure 1 To the attached Figure 3 As shown:

[0024] The utility model provides a road defect detection device, including a detection box 1, the bottom of the detection box 1 is hollowed out, and a top frame 2 is provided on the top. A display cover 3 is hinged on the top frame 2 for installing a display screen 33. When not in use, the display cover 3 is buckled on the top frame 2 to prevent the display screen 33 from accumulating dust. When in use, the display cover 3 can be flipped over to expose the display screen 33. A mounting frame 12 is provided in the detection box 1, and a mounting groove for clamping a probe 13 is provided at the bottom of the mounting frame 12. In this embodiment, the ultrasonic detector adopts the HC-U81 model, the display screen 33 is installed in the display cover 3, and the probe 13 is installed at the bottom of the detection box 1. The width of the detection box 1 is the same as the ground range detected by the probe 13.

[0025] Both sides of the detection box 1 are provided with notches running through the bottom, and mounting columns 4 are provided in the notches. The top of the mounting column 4 is rotatably connected to the detection box 1, and the axis of the mounting column 4 is located on the side wall edge of the detection box 1. An electric telescopic rod 5 is provided at the bottom of the mounting column 4, and the bottom output end of the electric telescopic rod 5 is connected to a supporting foot 6. The mounting column 4 can rotate on the detection box 1, and when the electric telescopic rod 5 extends the supporting foot 6 downward so that the supporting foot 6 contacts the ground and supports the detection box 1, the detection box 1 can rotate around the mounting column 4. A static gear 9 is provided on the mounting column 4, and a motor 11 is provided on the side wall of the detection box 1. The output shaft of the motor 11 is connected to a moving gear 10 meshing with the static gear 9. The motor 11 drives the moving gear 10 to rotate, and the static gear 9 meshing with it can make the detection box 1 rotate around the mounting column 4.

[0026] The bottom of the inner wall of the detection box 1 is provided with a roller 7. During the road surface detection process, the detection box 1 is moved along a vertical column on the road surface by the roller 7. A traction ring 8 is provided at the rear end of the detection box 1, which can be manually pulled to move the detection box 1. The probe 13 is responsible for detecting internal defects of the road and presenting data through the display screen 33. When the detection box 1 moves to the end of the road, the electric telescopic rod 5 extends the support foot 6 to support the ground. After the motor 11 drives the detection box 1 to rotate 180 degrees, the electric telescopic rod 5 retracts to make the roller 7 return to the road surface again, and a limiting convex plate 15 is provided on the support foot 6. After the electric telescopic rod 5 is extended to make the support foot 6 support the ground, the limiting convex plate 15 can still abut the inner wall of the detection box 1. The limiting convex plate 15 is used to limit the rotation angle of the detection box 1 so that it can only rotate back and forth within a 180-degree range around the mounting column 4, so that the detection box 1 automatically turns and is side by side with a previously tested column of road surface, reducing the omission of radar detection and the occurrence of repeated scanning of the road surface.

[0027] Among them, the support leg 6 is rectangular, one end extends to the center of the bottom of the detection box 1, and the other end extends symmetrically outside the detection box 1. After the electric telescopic rod 5 is extended to contact the support leg 6 with the ground to lift the detection box 1, the rectangle ensures the balance of the detection box 1, making it not easy to tip over.

[0028] Among them, a winding wheel 14 is provided in the detection box 1, and the axes at both ends of the winding wheel 14 are passed through the two side walls of the detection box 1. The winding wheel 14 can store cables that are wound too long. In addition to being placed in the mounting frame 12 for road detection, the probe 13 can also be removed. The cable stored in the winding wheel 14 can be used to pull the probe 13 to different environments for detection of detailed positions.

[0029] A fixing frame 31 is provided on the back of the display cover 3 , and a supporting plate 32 is hingedly connected to the fixing frame 31 . After the display cover 3 is flipped up, the supporting plate 32 can be used to support the top frame 2 .
