Description

Technical Field

[0001] The utility model relates to a bridge crack detection mechanism, belonging to the technical field of bridge crack detection. Background Art

[0002] As the name suggests, bridge crack detection is the process of detecting cracks in bridges, which aims to ensure the safety and stability of bridge structures. When bridges are put into use, some bridge decks are prone to cracks due to the nature of the materials. In order to ensure the safety of bridges, it is necessary to regularly detect cracks in bridges. When performing crack detection, a bridge crack detection device needs to be used.

[0003] Chinese patent CN211553783U discloses a bridge crack detection device, in which a detection camera on the top of a supporting plate can observe and detect the surface of the bridge, and universal wheels fixed on the top of telescopic rods on both sides of the top of the supporting plate outside the detection camera can contact the surface of the bridge, so that people can move the device to perform detection within a certain range. Springs at the bottom of the universal wheel and the top of the telescopic rod facilitate the universal wheel to encounter uneven areas on the bridge surface during movement, thereby cooperating with the telescopic rod to enable the universal wheel to move freely on the bridge surface. In this way, people can detect cracks in the bridge by transmitting the images captured by the detection camera to the crack detector. However, during detection, the detection module is often easily blocked by debris on the bridge surface, resulting in a decrease in detection accuracy. Some equipment with a cleaning structure can solve this problem, but the overall energy consumption of the equipment is extremely high, which is not conducive to long-term use. Therefore, a bridge crack detection mechanism is urgently needed to solve the above problem. Utility Model Content

[0009] Wherein, a mounting roller is fixedly mounted on the outside of the mounting shaft, the mounting roller is located below the machine body, and a plurality of wind fans are fixedly mounted on the outside of the mounting roller.

[0010] Among them, a wind speed increasing component is provided on the bottom surface of the body; the wind speed increasing component includes an air duct, the air duct is horizontally fixed on the bottom surface of the body, and the air inlet of the air duct is arranged toward the wind fan, the inner wall of the air duct is provided with an air flow groove, the air outlet of the air duct is fixedly installed with an air disk, the surface of the air disk is provided with a plurality of air outlet holes, and the interior of the air disk is provided with an air flow speed increasing volute.

The accelerated airflow can finally be sent out through a plurality of air outlets. These airflows can be blown sideways to the cleaning detection area to blow away some dust that has not been completely cleaned, and have a good cleaning effect, further improving the actual detection effect of the equipment.

[0022] See also Figures 1 to 5 , the utility model provides a technical solution:

[0023] A bridge crack detection mechanism includes a body 2 and a crack visual detection module. A push handle 1 is fixedly installed on the outer wall of one side of the body 2, a crack visual detection module is fixedly installed on the bottom surface of the body 2, a central control computer is provided on the top surface of the body 2, a drive component 3 is rotatably installed on the bottom of the body 2, the drive component 3 includes a drive shaft 32, the drive shaft 32 is rotatably installed inside the body 2, two drive wheels 31 are fixedly installed on the outside of the drive shaft 32, a worm sleeve 33 is fixedly installed at the middle position of the drive shaft 32, and a cleaning component 4 is rotatably installed on the inner wall of the top surface of the body 2.

[0024] A transmission assembly 5 is rotatably mounted on the inner wall of one side of the body 2. The transmission assembly 5 includes a transmission shaft 52, which is rotatably mounted on the inner wall of one side of the body 2. A transmission bevel gear 51 is fixedly mounted on one end of the transmission shaft 52, and a worm gear sleeve 53 is fixedly mounted on the outside of the transmission shaft 52. The worm sleeve 33 and the worm gear sleeve 53 are meshed with each other.

[0025] The cleaning assembly 4 includes a mounting shaft 41, which is rotatably mounted on the inner wall of the top surface of the body 2. A mounting chassis 45 is fixedly mounted on the bottom end of the mounting shaft 41, and two mounting bottom brushes 43 are fixedly mounted on the bottom surface of the mounting chassis 45. A cleaning brush 44 is fixedly mounted on the bottom surface of the two mounting bottom brushes 43. The transmission bevel gear 51 and the driven bevel gear 42 are meshed with each other.

[0026] The specific implementation method is as follows: during the actual use of the equipment, the push handle 1 is used to push the device to move on the detection surface, and the crack visual detection module is continuously turned on to perform crack detection on the bridge deck. When the equipment is displaced, the driving wheel 31 and the driving shaft 32 will rotate synchronously, and the worm sleeve 33 will rotate, which can drive the transmission shaft 52 with the worm gear sleeve 53 to rotate, and the transmission shaft 52 can drive the transmission bevel gear 51 to rotate, and the transmission bevel gear 51 can drive the installation shaft 41 with the driven bevel gear 42 to rotate, and the installation bottom brush 43 and the cleaning brush 44 can rotate synchronously to achieve effective cleaning of the detected bridge deck, creating a clearer detection environment for the crack visual detection module.

[0027] A driven bevel gear 42 and a mounting roller are fixedly installed on the outside of the mounting shaft 41. The driven bevel gear 42 is located above the mounting roller. Several wind fans 46 are fixedly installed obliquely on the outside of the mounting roller. The wind speed increasing component 6 includes an air duct 62. The air duct 62 is transversely fixed on the bottom surface of the body 2. The air inlet of the air duct 62 is arranged toward the wind fan 46. An air flow groove 61 is provided on the inner wall of the air duct 62. An air disk 63 is fixedly installed on the air outlet of the air duct 62. Several air outlet holes 64 are provided on the surface of the air disk 63. An air flow increasing volute 65 is provided inside the air disk 63.

[0028] The specific implementation method is as follows: when the cleaning component 4 rotates, several wind fans 46 will also rotate at the same time. When several wind fans 46 rotate, airflow can be generated in the air duct 62. These airflows can be quickly transmitted through the airflow groove 61 and finally reach the airflow speed increasing volute 65 of the wind disk 63. Since there is a narrow and long airway in the airflow speed increasing volute 65, these airflows will effectively increase the speed after passing through the airflow speed increasing volute 65. The accelerated airflow can finally be sent out through several air outlets 64, which can effectively side-blow the cleaning detection area, blow away some dust that has not been completely cleaned, and further improve the actual detection effect of the equipment.

[0029] The working principle of the above-mentioned bridge crack detection mechanism is as follows:

[0030] During the actual use of the equipment, the push handle 1 is used to push the device to move on the detection surface, and the crack visual detection module is continuously turned on to detect cracks on the bridge deck. When the equipment is displaced, the driving wheel 31 and the driving shaft 32 will rotate synchronously, and the worm sleeve 33 will rotate, which can drive the transmission shaft 52 with the worm gear sleeve 53 to rotate, and the transmission shaft 52 can drive the transmission bevel gear 51 to rotate, and the transmission bevel gear 51 can drive the installation shaft 41 with the driven bevel gear 42 to rotate, and the installation bottom brush 43 and the cleaning brush 44 can rotate synchronously to achieve effective cleaning of the detected bridge deck, creating a clearer inspection environment for the crack visual detection module. When the cleaning component 4 rotates, several wind fans 46 will also rotate at the same time. When the wind fans 46 rotate, airflow can be generated in the air duct 62. These airflows can be quickly conducted through the airflow slots 61 and finally reach the airflow speed increasing volute 65 of the wind disk 63. Since there is a long and narrow airway in the airflow speed increasing volute 65, these airflows will effectively increase the speed after passing through the airflow speed increasing volute 65. The accelerated airflow can finally be sent out through several air outlets 64, which can effectively side-blow the cleaned detection area, blow away some dust that has not been completely cleaned, and further improve the actual detection effect of the equipment.
