[0032] A longitudinal base 100, two ends of the length are respectively provided with a first longitudinal wheel set 110 and a second longitudinal wheel set 120, the first longitudinal wheel set 110 comprises a driving axle 111 and longitudinal rotating wheels arranged at both ends of the driving axle 111;

[0036] A lifting driving part 500 is installed on the longitudinal base 100 to drive the transverse base 400 to move vertically, wherein when the transverse base 400 is located at an upper position point, the first transverse wheel set 410 and the second transverse wheel set 420 are away from the ground, when the transverse base 400 is located at a lower position point, the first longitudinal wheel set 110 and the second longitudinal wheel set 120 are away from the ground, and the first bevel gear 210 and the second bevel gear 412 form a transmission matching;

[0037] A crack testing part 600 is installed at the bottom of the longitudinal base 100 and is arranged along the width of the longitudinal base 100.

[0038] In the prior art, the position transfer and data acquisition of the road crack detection device have respective problems, and the relationship between the two also has problems.

[0039] The road gap detection device provided by this utility model includes a longitudinal base 100, a power transmission shaft 200, a rotation drive unit 300, a transverse base 400, a lifting drive unit 500, and a gap testing unit 600.

[0040] A first longitudinal wheel assembly 110 and a second longitudinal wheel assembly 120 are respectively provided at both ends of the longitudinal base 100. The first longitudinal wheel assembly 110 includes a drive axle 111 and longitudinal rotating wheels disposed at both ends of the drive axle 111. The structure of the second longitudinal wheel assembly 120 can be similar to that of the first longitudinal wheel assembly 110. When the first longitudinal wheel assembly 110 and the second longitudinal wheel assembly 120 roll, the road gap detection device advances in length.

[0041] A power transmission shaft 200 is arranged in parallel below the drive wheel shaft 111 to form a transmission. A first bevel gear 210 is coaxially arranged on the power transmission shaft 200. The power transmission shaft 200 transmits the power from the drive wheel shaft 111. Only through the arrangement of the power transmission shaft 200 can the first horizontal wheel group 410 and the first vertical wheel group 110, with identical structures, alternately contact the ground.

[0042] A rotation drive unit 300 is mounted on the longitudinal base 100 to drive the first longitudinal wheel assembly 110 to rotate. The rotation drive unit 300 is preferably a motor, and more preferably a servo motor, so that the output status can be accurately monitored.

[0043] A horizontal base 400 is disposed below the vertical base 100. A first horizontal wheel assembly 410 and a second horizontal wheel assembly 420 are respectively disposed at both ends of the width of the horizontal base 400. The first horizontal wheel assembly 410 includes a driven wheel axle 411 and horizontally rotating wheels disposed at both ends of the driven wheel axle 411. The structure of the second horizontal wheel assembly 420 can be similar to that of the first horizontal wheel assembly 410. When the first horizontal wheel assembly 410 and the second horizontal wheel assembly 420 roll, the road gap detection device moves along its length and width. A second bevel gear 412 is coaxially disposed on the driven wheel axle 411. The driven wheel axle 411 is used to receive power from the power transmission shaft 200 (not continuously).

[0044] The lifting drive 500, mounted on the longitudinal base 100, drives the transverse base 400 to move vertically. During the lifting and lowering of the transverse base 400, the first transverse wheel assembly 410 and the second transverse wheel assembly 420 switch between not contacting the ground and contacting the ground, while the first longitudinal wheel assembly 110 and the second longitudinal wheel assembly 120 switch between contacting the ground and not contacting the ground.

[0045] When the lifting drive 500 drives the horizontal base 400 to the upper position, the first horizontal wheel assembly 410 and the second horizontal wheel assembly 420 move away from the ground, while the first longitudinal wheel assembly 110 and the second longitudinal wheel assembly 120 contact the ground. At this time, the power output from the rotation drive unit 300 drives the first longitudinal wheel assembly 110 to rotate, and the road gap detection device moves along the length of the road. The first bevel gear 210 and the second bevel gear 412 do not engage in this state, and the first horizontal wheel assembly 410 does not rotate.

[0046] When the lifting drive 500 drives the horizontal base 400 to the lower position, the first longitudinal wheel set 110 and the second longitudinal wheel set 120 move away from the ground, while the first transverse wheel set 410 and the second transverse wheel set 420 contact the ground, and the first bevel gear 210 and the second bevel gear 412 form a transmission engagement. At this time, the power output from the rotation drive unit 300 drives the first longitudinal wheel set 110 and the first transverse wheel set 410 to rotate, and the first longitudinal wheel set 110 and the second longitudinal wheel set 120 do not contact the ground, allowing the road gap detection device to move in the width direction of the road.

[0047] The gap testing unit 600 is installed at the bottom of the longitudinal base 100 and is arranged along the width of the longitudinal base 100. The gap testing unit 600 can be a high-resolution camera, a laser scanner, or an infrared sensor, etc. The operation of the gap testing unit 600 is not the focus of this utility model; the focus is on how to achieve precise movement of the road gap detection device.

[0048] By intermittently moving the road gap detection device along its length and width, a 90-degree bend was ultimately achieved. Combined with the operation of the gap testing unit 600, a complete and accurate scanning test of the road surface can be performed.

[0049] During the work process:

[0050] The testing method varies depending on the form of the gap testing unit 600. For example, if the gap testing unit 600 is fixed and cannot move, then the gap testing unit 600 needs to perform testing during the movement of the road gap detection device. Alternatively, if the gap testing unit 600 can move along its length, then after a certain displacement by the road gap detection device, the gap testing unit 600 completes the scanning action.

[0051] In summary, the lifting drive 500, mounted on the longitudinal base 100, drives the transverse base 400 to move vertically. When the lifting drive 500 drives the transverse base 400 to the upper position, the first transverse wheel group 410 and the second transverse wheel group 420 move away from the ground, and the device moves along the length of the road. When the lifting drive 500 drives the transverse base 400 to the lower position, the first longitudinal wheel group 110 and the second longitudinal wheel group 120 move away from the ground, and the device moves along the width of the road. Through the intermittent movement of the road gap detection device in the length and width directions, a 90-degree bend forward movement is finally achieved. Combined with the operation of the gap testing unit 600, a complete and accurate scanning test of the road surface can be performed.

[0052] In one embodiment, when the first bevel gear 210 and the second bevel gear 412 form a transmission engagement, the driving linear speeds of the first longitudinal wheel set 110 and the first transverse wheel set 410 are the same.

[0053] In this embodiment, when the road gap detection device moves in the length direction through the first longitudinal wheel group 110 and the first transverse wheel group 410 and the first transverse wheel group 410, the operation of the rotation drive unit 300 is consistent for the transfer displacement. Therefore, no proportional conversion is required in the displacement calculation process, which simplifies and reduces the calculation process.

[0054] In one embodiment, a linear drive is provided on the horizontal base 400, and the linear drive drives the gap testing part 600 to reciprocate in the length direction of the horizontal base 400.

[0055] In this embodiment, the gap testing unit 600 is reciprocated along the length of the transverse base 400 by a linear drive, thereby completing the scanning. During operation, after the road gap detection device completes a certain dimensional positional shift (either in the length or width direction) and stabilizes, the gap testing unit 600 is driven by a linear drive to complete the scanning, ultimately obtaining stable and accurate detection results. The linear drive can be pneumatic, hydraulic, electric, or screw-driven, etc.

[0056] In one embodiment, the linear drive is a lead screw drive type.

[0057] In this embodiment, the linear drive structure type has simple and stable characteristics.

[0058] In one embodiment, the longitudinal base 100 is provided with a guide structure corresponding to the transverse base 400.

[0059] In this embodiment, the vertical displacement of the horizontal base 400 is standardized by introducing a guide structure. The specific type of guide structure is not limited; it can be a shaft-hole fit or similar method.

[0060] In one embodiment, a Hall sensor is provided at the output end of the rotation drive unit 300.

[0061] In this embodiment, the operation of the rotation drive unit 300 is monitored by a Hall sensor, thereby monitoring the displacement of the road gap detection device.

[0062] In one embodiment, the width of the vertical base 100 is the same as the width of the horizontal base 400.

[0063] In this embodiment, the width of the lifting base 400 provides a basis for the stable movement of the road gap detection device.

[0064] In one embodiment, the length of the gap testing section 600 is the same as the width of the longitudinal base 100.

[0065] In this embodiment, the length of the gap testing unit 600 is consistent with the width of the longitudinal base 100, so that the gap testing unit 600 can perform detection on the entire area swept by the road gap detection device (specifically, the area swept by the longitudinal base 100). This structure improves the visibility of the entire working range of the gap testing unit 600.

[0066] Reference Figs. 3 to 4 In one embodiment, the lifting drive 500 is hydraulically driven, and the output end of the lifting drive 500 extends upward.

[0067] In this embodiment, the lifting drive 500 is configured as a hydraulic drive type, thereby providing a stable and reliable driving effect. Since the output end of the lifting drive 500 extends upwards, the horizontal base 400 will not exceed a predetermined size in the event of an accidental fall, reducing the possibility of the gap test section 600 colliding with the ground. The base of the lifting drive 500 is disposed on the upper surface of the vertical base 100, and the output end of the lifting drive 500 is disposed on the upper part of the base of the lifting drive 500.

[0068] In one embodiment, the gap testing unit 600 includes a camera unit and an ultrasonic unit spaced apart along the length of the horizontal base 400.

[0069] In this embodiment, by introducing multiple sensors, the road crack detection device can achieve multiple comprehensive performance characteristics. Both the camera unit and the ultrasonic unit need to be arranged along the width direction of the transverse base 400, thereby scanning and obtaining all road surface information along the width direction of the transverse base 400. When the camera unit is working, it acquires image information of the road surface, while the ultrasonic unit can obtain crack information at a certain depth in the road surface. The camera unit may include multiple cameras arranged in the width direction, and the ultrasonic unit may include multiple ultrasonic probes arranged in the width direction. During operation, the ultrasonic unit may need to be in close contact with the road surface, depending on the model.

[0070] In summary, the road gap detection device provided by this utility model has a lifting drive 500 installed on the longitudinal base 100 to drive the transverse base 400 to move vertically. When the lifting drive 500 drives the transverse base 400 to the upper position, the first transverse wheel group 410 and the second transverse wheel group 420 move away from the ground, and the device moves in the length direction of the road. When the lifting drive 500 drives the transverse base 400 to the lower position, the first longitudinal wheel group 110 and the second longitudinal wheel group 120 move away from the ground, and the device moves in the width direction of the road. Through the intermittent movement of the road gap detection device in the length and width directions, a 90-degree bend forward movement is finally achieved. Combined with the operation of the gap testing unit 600, a complete and accurate scanning test of the road surface can be performed.
