Description

Technical Field

[0001] The present application relates to the technical field of road and bridge detection, and in particular to a road and bridge detection device. Background Art

[0002] At present, with the development of national construction, there are more and more roads and bridges for vehicles to pass. As vehicles pass through the built roads and bridges, under the long-term rolling of a large number of vehicles, cracks of different sizes will appear on the surface of the roads and bridges. The generation of cracks will destroy the overall structure of the roads and bridges and reduce their service life. Therefore, it is necessary to detect and repair the cracks generated in the roads and bridges.

[0003] The existing solution is to use infrared detection technology to detect cracks in roads and bridges, determine the specific location of the cracks, and then perform manual repair work.

[0004] The above-mentioned existing technical solutions have the following defects: when a large number of vehicles pass by and in the open air environment where the roads and bridges are located, dust and dirt will be generated on the surface of the roads and bridges. The dust and dirt accumulated in and around the cracks will affect the infrared detection results, resulting in inaccurate detection results. Utility Model Content

[0005] The present application provides a road and bridge detection device in order to detect cracks on the surface of a road and bridge and solve the problem that dust and dirt accumulated on the surface of the road and bridge interfere with the detection results during the detection process.

[0006] The above technical objectives of this application are achieved through the following technical solutions:

[0007] A road and bridge inspection device includes a cleaning component and a support plate, the cleaning component includes a motor, a brush disk and a connecting shaft; the cleaning component is located at one end of the support plate, the motor is fixedly arranged on the upper surface of the support plate, the output shaft on the motor penetrates the support plate and is detachably connected to the end face of the connecting shaft, the connection between the output shaft and the connecting shaft is located inside the support plate, the brush disk includes a disk body connected to the connecting shaft, and the brush disk is installed below the support plate.

[0008] By adopting the above technical solution, during use, the detection device first drives the brush disc through the motor to clean the dust and dirt accumulated around the cracks on the surface of the road bridge below the detection device, and cleans it to both sides of the detection device. Then, as the detection device moves, the detection device passes over the cracks and detects the cracks. The setting of the cleaning component makes the cracks buried by dust and dirt more complete, which is conducive to the detection device to conduct a comprehensive detection of the cracks and makes the detection results of the detection device more accurate. After long-term use, the bristles are prone to wear and cannot effectively clean dust. The detachable brush disc is conducive to the replacement of the brush disc. The replaced brush disc ensures that the detection device is cleaned more thoroughly, which is conducive to the detection device to perform crack detection work.

[0009] Optionally, the cleaning component also includes a protruding fixing piece, which is fixedly arranged on the end face of the output shaft facing away from the motor, and a fixing groove is provided on the end face of the connecting shaft facing away from the brush disk. The protruding fixing piece is adapted to the fixing groove and can be removably inserted into the fixing groove.

[0010] By adopting the above technical solution, the motor drives the brush disc to rotate to clean the dust and accumulated dust on the surface of the road and bridge. The setting of the protruding fixing parts and the fixing grooves allows the output shaft to constrain the rotation direction of the connecting shaft, and at the same time can prevent the brush disc from slipping during the rotation process.

[0011] Optionally, an elastic part is provided inside the protruding fixing part, and fixed spring columns are provided at both ends of the elastic part. One end of the fixed spring column is spherical, and part of the spherical surface of the fixed spring column protrudes from the outer surface of the protruding fixing part. An inner groove is provided in the fixing groove, and the fixed spring column is adapted to the inner groove and can be inserted into the inner groove.

[0012] By adopting this technical solution, the brush disc itself is subjected to the downward force of gravity. The centrifugal force generated during rotation and the elastic force work together to firmly lock the fixing spring into the inner groove, thus securing the brush disc to the motor and preventing it from falling even during rotation. The built-in elastic member allows the fixing spring to contract under pressure, facilitating the removal of the brush disc.

[0013] Optionally, the cleaning component further includes a separation pin, which is plate-shaped, with a blade formed on one side of the separation pin. The blade of the separation pin is close to and can be inserted into the output shaft, and a spring is provided parallel to the side of the separation pin opposite to the output shaft.

[0014] By adopting the above technical solution, the separation pin does not contact the connection between the output shaft and the connecting shaft in a stationary state. When the separation pin is pressed, the separation pin contacts the connection between the output shaft and the connecting shaft and applies pressure until the brush disc is separated from the motor. The setting of the separation pin facilitates the replacement of the brush disc.

[0015] Optionally, at the connection point between the output shaft and the connecting shaft, the end face edges of the output shaft and the connecting shaft are processed to form chamfers with arcs.

[0016] By adopting the above technical solution, the chamfers of the output shaft and the connecting shaft are flared, which limits the movement position of the separation pin, facilitates the insertion of the separation pin between the output shaft and the connecting shaft, and facilitates the replacement of the brush disc.

[0017] Optionally, the detection device also includes a detection component, which includes a detector body, a speaker and a probe. The detector body is arranged at the other end of the upper surface of the support plate, the detector body is fixed to the support plate, the speaker is installed on the detector body, and the probe is installed at the bottom of the detector body, and the probe is perpendicular to the ground.

[0018] By adopting the above technical solution, the detection device can detect cracks on the surface of roads and bridges formed by a large number of vehicles passing through. When cracks are detected, the loudspeaker will sound to remind the staff, who will mark them to facilitate subsequent crack repair work.

[0019] Optionally, a directional wheel and a universal wheel are installed on the lower surface of the support plate, and the directional wheel is spaced apart from the brush disk.

[0020] By adopting the above technical solution, the provision of the directional wheels avoids the need for workers to manually move the detection device, and the provision of the universal wheels facilitates the steering of the detection device during use.

[0021] Optionally, the push rod is mounted on the same end plate surface of the support plate and the universal wheel.

[0022] By adopting the above technical solution, it is convenient for the staff to push the device during the use of the detection device.

[0023] Optionally, the detection device further includes a power supply, which is mounted on the upper surface of the support plate and electrically connected to the cleaning component and the detection component.

[0024] By adopting the above technical solution, the power supply provides power to the cleaning component and the detection component.

[0025] In summary, this application has the following technical effects:

[0026] 1. By installing a cleaning component, the detection device sweeps dust and dirt accumulated around cracks on the road and bridge surfaces below the detection device to both sides of the detection device, facilitating crack detection and providing more accurate detection results. After prolonged use, the bristles of the brush tend to wear and fail to effectively remove dust. The detachable brush plate facilitates replacement, ensuring a cleaner cleaning of the detection device.

[0027] 2. By providing the protruding fixing piece and the fixing groove, the output shaft can constrain the rotation direction of the brush disc and prevent the brush disc from slipping during rotation;

[0028] 3. The separation pin is set to facilitate the removal and replacement of the brush plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The present application is further described in detail below with reference to the accompanying drawings.

[0034] The embodiment of the present application discloses a road bridge detection device for detecting cracks caused by long-term rolling of road bridges by passing vehicles. Figure 1 The detection device comprises a cleaning component 1, a detection component 2, a base 3, and a power supply 4. During use, the base 3 is pushed to move the device along the surface of roads and bridges. The power supply 4 provides power to the cleaning component 1 and the detection component 2. The cleaning component 1 removes dust and dirt accumulated in and around cracks in roads and bridges, reducing the possibility of dust and dirt interfering with the detection device's detection work and facilitating the detection component 2 to accurately detect cracks later.

[0035] Reference Figure 1The base 3 includes a support plate 31, fixed wheels 32, universal wheels 33 and a push rod 34. The support plate 31 is a strip of metal plate, and the metal material ensures the durability of the base 3. Two identical fixed wheels 32 and universal wheels 33 are respectively provided. The two fixed wheels 32 are symmetrically mounted on one end of the lower surface of the support plate 31, and the two fixed wheels 32 are respectively located on both sides of the length direction of the support plate 31. The two universal wheels 33 are symmetrically mounted on the other end of the lower surface of the support plate 31, and the two universal wheels 33 are respectively located on both sides of the length direction of the support plate 32. The universal wheels 33 facilitate the steering of the device during use. The push rod 34 is U-shaped and both ends of the push rod 34 are fixedly mounted on the upper surface of the support plate 34 on the side close to the universal wheels 33. The push rod 3 is tilted from bottom to top toward the outside of the edge of the support plate 31, which allows the staff to push the device more conveniently. During use, force is applied to the push rod 34 to rotate the fixed wheels 32 and the universal wheels 33, which allows the device to be moved more conveniently.

[0036] Reference Figure 1 、 Figure 2 and Figure 3 The cleaning component 1 includes a motor 11, an output shaft 12, a brush disc 17 and a connecting shaft 171. The cleaning component 1 is located on one end of the support plate 31 near the directional wheel 32. Two motors 11 are symmetrically arranged and installed on the upper surface of the support plate 31. The connecting line of the two motors 11 is perpendicular to the length direction of the support plate 31, and the motor 11 is fixed to the support plate 31. The output shaft 12 extends outward from the inside of the motor 11 and penetrates the support plate 31. The brush disc 17 is located below the support plate 31. The brush disc 17 is equipped with cloth strip bristles, and the bristles are close to the ground. Two identical brush discs 17 are symmetrically arranged. The brush disc 17 consists of a truncated cone-shaped main body and a connecting shaft 171 with one end fixed to the smaller end face of the cone. The connecting shaft 171 is coaxial with the cone. The two brush discs 17 are connected to the two output shafts 12 via connecting shafts 171. The two brush discs 17 are spaced apart and have the same horizontal height. The closest bristles on the two brush discs 17 can overlap, preventing dust and dirt from being trapped between the two brush discs 17 during cleaning. The brush discs 17 are spaced apart from the directional wheels 32 to prevent the bristles from being caught in the directional wheels 32, thereby reducing bristle loss. When the motor 11 is powered on, it drives the brush discs 17 to rotate, sweeping dust and dirt from the road and bridge pavement that the detection device passes to the left and right sides of the detection device, allowing the detection component 2 to more accurately detect whether there are cracks in the road and bridge pavement after cleaning.

[0037] Reference Figure 2 and Figure 3The cleaning component 1 also includes a protruding fixing part 13, a fixed spring column 15 and a separation pin 18. The protruding fixing part 13 is a rectangular parallelepiped, which is integrally formed and arranged on the end face of the output shaft 12. The protruding fixing part 13 is located in the center of the end face of the output shaft 12. A fixing groove 14 is provided on the end face of the connecting shaft 171 away from the cone. The fixing groove 14 is adapted to the protruding fixing part 13 and the protruding fixing part 13 can be inserted into the fixing groove 14. The combination of the protruding fixing part 13 and the fixing groove 14 ensures that the brush disc 17 does not slip during rotation. The fixed spring column 15 is a cylinder, and two identical ones are provided. One end of the fixed spring column 15 is processed to form a spherical surface, and the two fixed spring columns 15 are installed on the opposite sides of the protruding fixing part 13. A hole is drilled along the length of the outer surface of the protruding fixing member 13, extending through the hole. A spring is placed in the hole and fixed in the center of the hole. Two fixing springs 15 are fixed to the ends of the spring, with their spherical surfaces facing each other. The spherical surfaces of the fixing springs 15 protrude from the outer surface of the protruding fixing member 13. An inner groove 16 is defined on the end surface of the connecting shaft 171 facing away from the brush disc 17. The spherical surface of the fixing spring 13 protruding from the outer surface of the protruding fixing member 13 mates with the inner groove 16 in the fixing groove 14. When the output shaft 12 is connected to the connecting shaft 171, the fixing spring 15 protruding from the outer surface of the protruding fixing member 13 engages with the inner groove 16, further securing the brush disc 17 and preventing it from falling during use.

[0038] Reference Figure 1 and Figure 3 The separation latch 18 is located inside the base 3, and two symmetrical separation latches 18 are provided on the support plate 31. The separation latch 18 is embedded from the side of the support plate 31 on the outside of the two output shafts 12. The separation latch 18 is plate-shaped, and a blade is formed on one side of the length direction of the separation latch 18. The thickness of the separation latch 18 gradually increases from the blade to the other side. The blade is close to and can be inserted into the connection between the output shaft 12 and the connecting shaft 171. A spring is provided parallel to the side of the separation latch 18 away from the output shaft 12. The part of the separation latch 18 located outside the support plate 31 is processed to form a pressing rod. The overall length of the pressing rod is greater than the length of the spring. The spring can make the pressed separation latch 18 rebound. The output shaft 12 and the connecting shaft 171 have the same diameter, and the end face edges where the output shaft 12 and the connecting shaft 171 are connected are processed to form a chamfer with an arc. The chamfers of the output shaft 12 and the connecting shaft 171 are flared, which facilitates contact with the separation latch 18 and limits the separation latch 18 .

[0039] Reference Figure 3In the static state, the release latch 18 does not contact the connection between the output shaft 12 and the brush disk 17. Pressing the release latch 18 inward, the release latch 18 contacts the flared chamfer at the connection between the output shaft 12 and the connecting shaft 171. The thickness of the flared chamfer gradually increases, and the contact position moves inward into the flared chamfer. The output shaft 12 and the connecting shaft 171 are squeezed and separated. The inner groove 16 moves, compressing the fixed springs 15. The two fixed springs 15 compress the springs and contract until the connecting shaft 171 separates from the output shaft 12. The provision of the release latch 18 facilitates the replacement of the brush disk 17.

[0040] Reference Figure 1 The detection component 2 includes a detector body 21, a speaker 22 and a probe 23. The detection component 2 is installed as a whole on the upper surface of the support plate 31 near one end of the universal wheel 32, and the detection component 2 is spaced apart from the push rod 34. The support plate 31 below the detection component 2 is hollow, and the probe 23 extends from the bottom of the detector body 21, perpendicular to the ground. The speaker 22 is above the detector body 21. During the detection process, the probe 23 emits infrared rays to detect the road surface. When cracks are detected, the speaker 22 is controlled to alarm, making it convenient for inspectors to find cracks and mark them.

[0041] Reference Figure 1 The power supply 4 is mounted on the upper surface of the support plate 31 and is located between the motor 11 and the detection component 2. It is electrically connected to the motor 11 and the detection component 2 through wires, providing power to the motor 11 and the detection component 2, and can be repeatedly charged to ensure the operation of the device.

[0042] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but as long as they are within the scope of the claims of the present application, they are protected by the patent law.
