Description

Technical Field

[0001] This utility model relates to the field of crack detection technology, specifically to a road and bridge crack detection device. Background Technology

[0002] Existing road and bridge crack detectors are mainly divided into a main unit and a probe. During operation, one hand needs to hold the main unit and the other hand needs to hold the probe close to the crack for scanning and identification. In actual use, the inspector needs to squat down to use the probe to inspect the road surface, which is very inconvenient and can easily cause discomfort and fatigue after a long period of operation.

[0003] A search revealed a Chinese patent, CN 221918876 U, which discloses a road and bridge crack detection device, relating to the field of crack detection. The device includes a connecting rod with a handle fixedly connected to its upper end, and a mounting plate rotatably connected to the lower end of the connecting rod via a rotating shaft. A torsion spring connects the rotating shaft and the mounting plate. Four movable wheels are rectangularly distributed at the four corners of the mounting plate and rotatably connected to it. This invention, by providing movable wheels at each of the four corners of the mounting plate and a torsion spring between the rotating shaft on the connecting rod and the mounting plate, allows the probe to maintain a high degree of verticality to the ground when moved by the operator using the handle and connecting rod. This effectively improves the accuracy of the probe in scanning and identifying ground cracks.

[0004] In actual use, it is not convenient to adjust the height of the lower end of the probe from the road surface. When there are obstacles on the road surface (such as sand and gravel), if the height of the probe is not adjusted, the probe may collide with the obstacle and be damaged during the movement of the device, resulting in poor safety and economy.

[0005] Therefore, in order to address the above problems, a road and bridge crack detection device is proposed. Utility Model Content

[0006] This invention addresses the shortcomings of existing technologies by developing a road and bridge crack detection device. This invention enables the detection probe to avoid contact with obstacles during the detection process, thereby improving the safety and economy of road and bridge crack detection.

[0007] To achieve the above objectives, this utility model employs the following technical solution:

[0008] A road and bridge crack detection device includes a base plate with a detection port through the center. A movable wheel is mounted on the bottom of the base plate, and a support rod is mounted on one end. A groove is mounted on the base plate, and a sliding groove is formed on one side wall of the groove. The length direction of the groove is perpendicular to the surface of the base plate. A lifting block is slidably mounted within the groove, and the sliding direction of the lifting block is parallel to the length direction of the groove. The lifting block is connected to a lifting assembly, which is mounted on the groove and used to drive the lifting block to move up and down. A detection probe is connected to the lifting block via an mounting assembly. The detection probe can move with the lifting block and can pass through the detection port through its movement. An equipment box is mounted on the support rod, and a main unit is mounted inside the equipment box. The main unit is electrically connected to the detection probe.

[0009] Preferably, the lifting assembly includes a lead screw, which is rotatably disposed inside the slide groove, and the axis of the lead screw is parallel to the length direction of the slide groove. The lead screw is threadedly connected to the lifting block. The upper end of the lead screw is connected to the output end of the lifting power component, which is disposed at the upper end of the slide rod. An adapter shaft is disposed at the bottom end of the lead screw. An adapter cylinder is disposed on the base plate, and a cavity is opened on the adapter cylinder. The adapter shaft is inserted into the cavity and rotatably connected to the adapter cylinder.

[0010] Preferably, two support poles are provided, and the equipment box is placed between the two support poles. An auxiliary handle is provided at the end of each support pole away from the base plate, and a controller is provided on one side of the auxiliary handle. The controller is electrically connected to the lifting power component.

[0011] Preferably, the mounting assembly includes a slot block, which is set on the lifting block. A T-shaped slot is opened on the slot block. The length direction of the T-shaped slot is parallel to the axis of the lead screw. The T-shaped slot is a non-through slot with an open top. A T-shaped plug is inserted into the T-shaped slot. There is damping between the T-shaped plug and the T-shaped slot. The T-shaped plug is connected to the outer wall of the detection probe.

[0012] Preferably, the system also includes a sensing plate, which is rotatably mounted on the bottom side of the front end of the substrate in the forward direction via a rotating shaft. The axis of the rotating shaft is perpendicular to the forward direction of the substrate and parallel to the surface of the substrate. A sensing sheet is mounted on the front side of the sensing plate, and the sensing sheet is electrically connected to the controller. The height of the bottom end of the sensing plate is the same as the height of the bottom end when the detection probe moves to the bottom.

[0013] The effects provided in the utility model description are merely those of the embodiments, and not all the effects of the utility model. The above technical solution has the following advantages:

[0014] 1. By setting up a lifting component, this utility model can lift the detection probe when it encounters an obstacle during the device's movement and detection process, so as to cross the obstacle. This avoids the detection probe being too low and colliding with the obstacle on the road surface, thus improving the safety of the device, avoiding the need for maintenance and replacement of the detection probe, and improving the economic efficiency of the device.

[0015] 2. By setting up installation components, the detection probe can be quickly installed and removed, improving maintenance efficiency;

[0016] 3. By setting up a sensor plate, the detection probe can be automatically raised when the operator does not see the obstacle, which improves the practicality of the device. Attached Figure Description

[0024] 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.

[0025] like Figures 1-5 As shown, this utility model provides a technical solution:

[0026] A road and bridge crack detection device includes a base plate 1 with a detection port 2 extending through the center of the base plate 1. A movable wheel 3 is provided at the bottom of the base plate 1. A support rod 9 is provided at one end of the base plate 1. A groove rod 4 is provided on the base plate 1, located on one side of the detection port 2. A sliding groove is formed on the side wall of the groove rod 4 near the detection port 2, with the length direction of the groove perpendicular to the surface of the base plate 1, i.e., perpendicular to the ground. A lifting block 7 is slidably disposed within the groove, with the sliding direction of the lifting block 7 parallel to the length direction of the groove. The lifting block 7 is connected to a lifting assembly, which is mounted on the groove rod 4 and used to drive the lifting block 7 to move up and down. A detection probe 8 is connected to the lifting block 7 via an installation assembly. The detection probe 8 can move with the lifting block 7 and can pass through the detection port 2 through its movement. An equipment box 10 is provided on the support rod 9, and a main unit 11 is provided inside the equipment box 10. The main unit 11 is a common type of crack detection equipment on the market, and the main unit 11 is electrically connected to the detection probe 8.

[0027] In an optional embodiment, the lifting assembly includes a lead screw 5, which is rotatably disposed inside the slide groove, and the axis of the lead screw 5 is parallel to the length direction of the slide groove. The lead screw 5 is threadedly connected to the lifting block 7. The upper end of the lead screw 5 is connected to the output end of the lifting power component 6, which is a motor. The lifting power component 6 is disposed at the upper end of the groove rod 4. The bottom end of the lead screw 5 is coaxially connected to the adapter shaft 13. An adapter cylinder 12 is disposed on the base plate 1, and a cavity is opened on the adapter cylinder 12. The adapter shaft 13 is inserted into the cavity and rotatably connected to the adapter cylinder 12 to ensure the stability of the lead screw 5 when rotating.

[0028] In an optional embodiment, two support poles 9 are provided, and the equipment box 10 is located between the two support poles 9. An auxiliary handle 14 is provided at the end of each support pole 9 away from the base plate 1. A controller 15 is provided on one side of the auxiliary handle 14. The controller 15 can be a commonly available control switch. The controller 15 is electrically connected to the lifting power component 6 and is used to control the forward and reverse rotation of the output end of the lifting power component 6, thereby improving the efficiency of the device.

[0029] In an optional embodiment, the mounting assembly includes a slot 16, which is disposed on the lifting block 7. A T-shaped slot is formed on the slot 16, and the length direction of the T-shaped slot is parallel to the axis of the lead screw 5. The T-shaped slot is a non-through slot with an open top. A T-shaped insert is inserted into the T-shaped slot and is connected to the outer wall of the detection probe 8. There is damping between the T-shaped insert and the T-shaped slot. The damping can be achieved by setting a thin rubber layer on the outer surface of the T-shaped insert to prevent the detection probe 8 from shifting or falling out during movement, thereby improving the stability of the device.

[0030] In an optional embodiment, a sensing plate 18 is also included. The sensing plate 18 is rotatably mounted on the bottom side of the front end of the substrate 1 in the forward direction via a rotating shaft, and the axis of the rotating shaft is perpendicular to the forward direction of the substrate 1 and parallel to the surface of the substrate 1. The sensing plate 18 can be flipped backward. A sensing sheet is provided on the front surface of the sensing plate 18. The sensing sheet is a commonly available touch sensor or an electro-sensor, which can generate an electrical signal when the sensing sheet comes into contact with an obstacle. The sensing sheet is electrically connected to the controller 15. Preferably, the sensing sheet is connected to the control circuit in the controller 15 for controlling the lifting of the detection probe 8. The height of the bottom end of the sensing plate 18 is the same as the height of the bottom end of the detection probe 8 when it moves to the bottom. When a small movable obstacle comes into contact with the sensing plate 18, it may be pushed to one side by the sensing plate 18. However, when a larger obstacle or an obstacle fixed on the road surface comes into contact with the sensing plate 18, the sensing plate 18 flips backward to make way for the obstacle, which can further protect the device and extend the service life of the device.

[0031] In an optional embodiment, a rechargeable battery is also provided on the substrate 1, and the battery is electrically connected to each power-consuming component to provide power for the overall use of the device.

[0032] Working principle: First, the device is moved to the road bridge to be inspected. Then, the detection probe 8 is moved downwards to a detectable height. The device is pushed forward by the auxiliary handle 14, allowing the detection probe 8 to inspect the road bridge. When an obstacle appears in the path ahead of the device, the operator can manually operate the controller 15 to energize the lifting power component 6, which moves the detection probe 8 upwards to a height no less than that of the obstacle, allowing the detection probe 8 to cross the obstacle. Then, the detection probe 8 is lowered back to its original position. If the operator fails to detect the obstacle in time or fails to operate the controller 15 in time, the obstacle will contact the sensing plate on the sensing plate 18. The sensing plate will cause the controller 15 to automatically activate the lifting power component 6, moving the detection probe 8 upwards. After the detection probe 8 crosses the obstacle, the operator can manually control the detection probe 8 to lower it back to its original position.
