DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] like Figure 1 and Figure 2 As shown, a road and bridge crack detection device includes a main shell 1, a driving component 2 is provided at the lower rear part of the right end of the main shell 1, a shielding component 3 is provided at the lower front part of the right end of the main shell 1, a detector 4 is fixedly connected to the front side of the inner cavity of the main shell 1, a marking component 5 is provided at the rear side of the inner cavity of the main shell 1, a rectangular groove 1 6 is opened at the lower front part of the right end of the main shell 1, and a rectangular groove 2 7 is opened at the front part of the lower inner surface of the main shell 1.

[0026] The main body shell 1 is composed of a push handle, a fixed box and four wheels;

[0027] The detector 4 mentioned above is composed of a control panel, a detection body, and a detection probe. It is a mature technical means in the prior art. This solution only describes the coordination process between it and other components. As for the process and method of detecting road and bridge cracks, this solution will not elaborate on it here.

[0028] In a specific implementation, the inspection personnel move the device to the position where the road and bridge cracks are to be inspected. During this movement, the shielding component 3 shields the detection probe of the detector 4 to prevent the detection probe from being damaged during the movement, thereby affecting the road and bridge crack detection process;

[0029] The detector 4 described above generally uses existing technologies such as ultrasonic, laser, or image recognition to detect cracks. For example, ultrasonic crack detectors transmit ultrasonic waves and receive their reflected signals, calculating the crack depth based on the time difference between the signals. Image recognition technology, on the other hand, uses algorithms to automatically identify and measure the width and depth of cracks by taking a photo of the road surface. The HC-F600 comprehensive crack detector from the Haichuang Hi-Tech series can be used: This comprehensive crack detector integrates multiple functions such as crack depth and width measurement and is suitable for crack detection in concrete pavements.

[0030] Turn on the driving component 2, so that the shielding component 3 runs and no longer blocks the detection probe of the detector 4. Then turn on the detector 4 to start detecting cracks in the road and bridge. When the detector 4 detects cracks in the road and bridge, turn on the driving component 2, so that the marking component 5 runs and marks the detected cracks, which facilitates the subsequent processing of the cracks.

[0031] Specifically, in order to protect the detection probe of the detector 4 when the device is not in use, to prevent the detection probe from being damaged, thereby affecting the road and bridge crack detection work, refer to Figure 3The driving component 2 includes a dual-axis motor 22, which is fixedly connected to the lower rear portion of the right end of the main shell 1. The left output end of the dual-axis motor 22 is fixedly connected to a rotating rod 21 through a coupling, and the right output end of the dual-axis motor 22 is fixedly connected to a rotating rod 23 through a coupling. The right side of the outer surface of the rotating rod 23 is fixedly connected to a bevel gear 24; the shielding component 3 includes a rectangular box 32, which is fixedly connected to the lower front portion of the right end of the main shell 1, passes through the right side of the rear end of the rectangular box 32 and extends to the rectangular box. A threaded rod 33 is rotatably connected in the rectangular box 32, and a bevel gear 2 31 is fixedly connected to the rear side of the outer surface of the threaded rod 33. The bevel gear 1 24 is meshed with the bevel gear 2 31, and a slide 35 is threadedly connected to the outer surface of the threaded rod 33. Limiting components are provided on the upper and lower sides of the slide 35, and a baffle 36 is fixedly connected to the left side of the front end of the slide 35; the limiting component includes two sliding grooves 341, and the two sliding grooves 341 are respectively opened on the upper and lower sides of the inner surface of the rectangular groove 1 6, and the slide 35 is slidably connected to the inner surfaces of the two sliding grooves 341.

[0032] The dual-axis motor 22 is a motor system with two independent drive shafts. These two shafts can be controlled independently, or can achieve synchronous or differential motion through a control system.

[0033] The two shafts are linked by gears and controlled by a clutch, which can be engaged or disconnected as needed. This structure enables the motor to drive the loads on the two shafts simultaneously or separately.

[0034] It is a mature technical means in the existing technology. This solution only uses its function of controlling the system to make the two axes run simultaneously or differently. Its structure and working principle will not be elaborated here.

[0035] In specific practice, the device is moved to the position for detecting cracks in the road and bridge. At this time, the shielding plate 36 is in a state of shielding the rectangular slot 2 7. The dual-axis motor 22 is turned on to drive the rotating rod 2 23 to rotate forward, thereby driving the bevel gear 1 24 to rotate. Since the bevel gear 1 24 and the bevel gear 2 31 are engaged, the rotation of the bevel gear 1 24 drives the bevel gear 2 31 to rotate, thereby driving the threaded rod 33 to rotate, thereby driving the slide plate 35 to move toward the direction close to the bevel gear 2 31, thereby driving the shielding plate 36 to move toward the direction close to the bevel gear 2 31, so that the shielding plate 36 no longer blocks the rectangular slot 2 7. Then the detection probe of the detector 4 can detect cracks in the road and bridge through the rectangular slot 2 7, and then the detector 4 is turned on to start detecting cracks in the road and bridge.

[0036] When the road bridge crack detection is not needed, the dual-axis motor 22 is turned on to drive the second rotating rod 23 to reverse. Under the same principle as above, the shielding plate 36 moves away from the second bevel gear 31 until the second rectangular groove 7 is completely covered. At this time, the detection probe is also covered to prevent the detection probe from being damaged when not in use.

[0037] The two sliding grooves 341 can limit the moving path of the slide plate 35 when the threaded rod 33 rotates to drive the slide plate 35 to move, so that the slide plate 35 moves horizontally.

[0038] Specifically, in order to mark the cracks in time when the detector 4 detects the cracks in the road bridge, thereby facilitating the subsequent road bridge crack treatment work, refer to Figure 4 The marking assembly 5 includes a charging box 51, which is fixedly connected to the rear portion of the lower inner surface of the main shell 1. A circular box cover 52 is threadedly connected to the upper outer surface of the charging box 51. A driven assembly 53 is provided on the upper inner side of the charging box 51, and a piston assembly 54 is provided on the lower inner side of the charging box 51.

[0039] Further reading Figure 5 The driven assembly 53 includes a pulley 531, the lower pulley 531 is fixedly connected to the outer surface of the rotating rod 21, and the inner surface of the upper pulley 531 is fixedly connected to a round rod 532, the left end of the round rod 532 passes through the upper rear part of the right end of the main shell 1 and the upper side of the right end of the charging box 51 and extends into the charging box 51, the left end of the round rod 532 is fixedly connected to a disc 533, and the upper side of the left end of the disc 533 is fixedly connected to a round block 534; the piston The component 54 includes a piston 542, and the outer surface of the piston 542 is rotatably connected to a connecting rod 541. The upper side of the connecting rod 541 is rotatably connected to the outer surface of the round block 534. The lower side of the inner surface of the charging box 51 is fixedly connected to a through cylinder 543. The piston 542 is slidably connected to the inner surface of the cylinder 543. The middle part of the outer surface of the cylinder 543 is fixedly connected to a through one-way valve 1 544, and the lower end of the cylinder 543 is fixedly connected to a through one-way valve 2 545.

[0040] In the specific implementation, the circular box cover 52 is unscrewed, liquid pigment for marking is injected into the loading box 51, and then the circular box cover 52 is screwed on. When the detector 4 detects cracks in the road bridge, the dual-axis motor 22 is turned on to drive the rotating rod 21 to rotate alone. Under the action of the pulley 531, the rotating rod 21 rotates and drives the circular rod 532 to rotate, thereby driving the disc 533 and the round block 534 to rotate, thereby driving the connecting rod 541 to move, and driving the piston 542 to slide back and forth in the cylinder 543, thereby changing the air volume in the cylinder 543, so that a pressure difference occurs between the loading box 51 and the cylinder 543, so that the one-way valve 1 544 and the one-way valve 2 545, which were originally in a closed state, are opened, so that the liquid pigment in the loading box 51 enters the cylinder 543 through the opened one-way valve 1 544, and then flows out of the cylinder 543 through the opened one-way valve 2 545, marking the detected cracks.

[0041] It should be noted that the specific installation method, circuit connection method and control method of the dual-axis motor 22 and the detector 4 used in the present invention are all conventional designs and will not be elaborated in detail in the present invention.

[0042] The working principle of this utility model is:

[0043] The inspector moves the device to the position where the road and bridge cracks are to be inspected, then turns on the dual-axis motor 22 to drive the rotating rod 23 to rotate forward. Under the meshing action of the bevel gear 1 24 and the bevel gear 2 31, the threaded rod 33 rotates, thereby moving the shielding plate 36 so that it no longer blocks the rectangular groove 2 7. Then, the detector 4 is turned on to start inspecting the road and bridge cracks.

[0044] Liquid pigment is injected into the loading box 51. After cracks in the road bridge are detected, the dual-axis motor 22 is turned on to drive the rotating rod 1 21 to rotate alone. Under the action of the pulley 531, the round rod 532 is rotated, thereby driving the disc 533 and the round block 534 to rotate, so that the connecting rod 541 moves and drives the piston 542 to move back and forth up and down in the cylinder 543, so that the one-way valve 1 544 and the one-way valve 2 545 that were originally in the closed state are opened, so that the liquid pigment in the loading box 51 flows out of the loading box 51 through the opened one-way valve 1 544 and the one-way valve 2 545, thereby marking the detected cracks.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
