Description

Technical Field

[0001] This utility model relates to the field of construction engineering, and in particular to a crack detection device for construction engineering. Background Technology

[0002] Construction projects refer to the physical structures formed through the construction of various types of buildings and their ancillary facilities, as well as the installation of supporting lines, pipelines, and equipment. "Building construction" specifically refers to projects with structures such as roofs, beams, columns, walls, and foundations, capable of forming internal spaces to meet people's needs for production, living, learning, and public activities. To ensure safety, these projects are typically inspected. The inspection of construction projects includes crack detection.

[0003] Current crack detection methods utilize two ultrasonic transmitters to detect cracks on both sides of the crack. By measuring three data points at different intervals, the crack depth is calculated using the principle of a triangle structure. However, existing detection devices require manual measurement and movement of the ultrasonic transmitters, which is prone to errors and increases labor costs.

[0004] Therefore, there is a need to design an automated crack detection device for construction projects to improve detection accuracy and reduce manpower input. Utility Model Content

Detailed Implementation

[0030] 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.

[0031] Example: A crack detection device for construction projects, such as... Figures 1-11As shown, the system includes a controller 1, connectors 2, transmission lines 3, ultrasonic transmitters 4, connecting parts 5, a first slide rail 6, first sliding blocks 7, first electric push rods 8, a support frame 9, and a frame 12. Two connectors 2 are slidably connected to the bottom right side of the controller 1. Both connectors 2 can slide freely back and forth on the bottom of the controller 1, and the controller 1 is electrically connected to the connectors 2. Each connector 2 is electrically connected to a transmission line 3, and the other end of each transmission line 3 is electrically connected to an ultrasonic transmitter 4. The two ultrasonic transmitters 4 are symmetrically distributed, and each ultrasonic transmitter 4 has a connecting part 5 fixedly connected to its top. The bottom of the controller 1 is fixedly connected to the first slide rail 6, and two first sliding blocks 7 are slidably connected to the first slide rail 6. The bottom of each first sliding block 7 is fixedly connected to a first electric push rod 8, and the piston rods of each first electric push rod 8 are fixedly connected to the two connecting parts 5 respectively. Therefore, the ultrasonic transmitter 4 can only move back and forth and move up and down using the first electric push rods 8. Furthermore, when the ultrasonic transmitter 4 moves back and forth, it will restrain the connector 2 from moving back and forth. The bottom of the controller 1 is also fixedly connected to the front and rear ends of the support frame 9 to support the entire device. The controller 1 is fixedly connected to the frame 12 around its perimeter, and also includes an electric slide rail 13, a slider 14, a connecting rod 16, a cleaning brush 17, and a push ring 18. The electric slide rail 13 is fixedly connected to the bottom right side of the frame 12. The slider 14 is slidably connected to the electric slide rail 13. The connecting rod 16 is welded to the bottom of the slider 14. The cleaning brush 17 is slidably connected to the connecting rod 16. The push ring 18 is fixedly connected to the rear side of the connecting rod 16. The push ring 18 is sleeved on the ultrasonic transmitter 4. The controller 1 is electrically connected to the electric slide rail 13 and can control the electric slide rail 13 to achieve high-precision sliding. Therefore, when the electric slide rail 13 is started, the ultrasonic transmitter 4 can be moved back and forth through the connecting rod 16 to achieve high-precision moving measurement. At the same time, the connecting rod 16 can drive the cleaning brush 17 to clean the measurement position, making the measurement results more accurate.

[0032] like Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, it also includes a second electric push rod 10 and a universal wheel 11. There are second electric push rods 10 on both the left and right sides of the support frame 9. Universal wheels 11 are fixedly connected to the piston rods at the bottom of the four second electric push rods 10. Activating the second electric push rods 10 can cause the universal wheels 11 to move downward, thereby supporting the entire device and driving the entire device to move.

[0033] like Figure 7 and Figure 8 As shown, it also includes an indicator 15. The left side of each slider 14 is fixedly connected to the indicator 15, and the left side of the frame 12 is engraved with a scale. The indicator 15 moves along with the slider and points to the corresponding scale, allowing the operator to see the measurement distance more clearly.

[0034] like Figure 1 , Figure 2 , Figure 3 and Figure 9 As shown, it also includes a second slide rail 19, a second sliding block 20, and a third electric push rod 21. The second slide rail 19 is also fixedly connected to the bottom right side of the frame 12. Two second sliding blocks 20 are slidably connected to the second slide rail 19. The left side of each of the two second sliding blocks 20 is fixedly connected to the third electric push rod 21 by bolts. The movable rod of the third electric push rod 21 is fixedly connected to the cleaning brush 17, and the cleaning brush 17 is slidably connected to the connecting rod 16, allowing it to move left and right. Therefore, starting the third electric push rod 21 can drive the cleaning brush 17 to move left and right, thereby making the measurement position cleaner.

[0035] like Figure 3 and Figure 9 As shown, it also includes a vacuum cleaner 22, an air pump 23, a telescopic tube 24, and a dust collection device 25. The vacuum cleaner 22 is welded to the side of the two cleaning brushes 17 that are far apart from each other. The air pump 23 is welded to the bottom of the front and rear sides of the left side of the controller 1. The telescopic tube 24 is fixedly connected between the vacuum cleaner 22 and the air pump 23. The dust collection device 25 is threadedly connected to both air pumps 23. The telescopic tube 24, the air pump 23, and the dust collection device 25 are connected. Therefore, the vacuum cleaner 22 can suck up the dust cleaned by the cleaning brushes 17 and enter the dust collection device 25 through the telescopic tube 24, thus playing a dust removal role.

[0036] like Figure 10 As shown, it also includes a cover 27. A placement groove 26 is provided on the top left side of the frame 12, and the cover 27 is rotatably connected to the placement groove 26 on the frame 12. Therefore, the operator can place Vaseline in the placement groove 26.

[0037] like Figure 1 and Figure 10 As shown, it also includes a dust cover 28, which is rotatably connected to the top right side of the frame 12 and covers the controller 1.

[0038] When crack detection is required, first place the device at the center of the crack, making the crack perpendicular to the device. If adjustment is needed, activate the second electric push rod 10 to move the casters 11 downwards. The four casters 11 support the entire device. Then, push the frame 12 to move the entire device to the designated location. Activate the second electric push rod 10 again to reset the casters 11. Then, activate the two third electric push rods 21 on both sides of the bottom of the frame 12. The two third electric push rods 21 move the cleaning brushes 17 left and right to clean the measurement area. Next, activate the two air pumps 23. The air pumps 23 drive the vacuum cleaner 22 to collect the dust and debris particles cleaned by the front and rear cleaning brushes 17. Finally, activate the two first electric push rods 8 to move the two ultrasonic transmitters 4 upwards. The ultrasonic transmitter 4 is moved away from the ground. Then the dust cover 28 is opened. The controller 1 is activated to start the electric slide rails 13 on both sides, which drive the two cleaning brushes 17 to move away from each other. At the same time, the vacuum cleaner 22 collects the dust and debris particles cleaned by the cleaning brushes 17, thereby achieving the cleaning effect. The debris sucked in by the vacuum cleaner 22 will enter the dust collection parts 25 on both sides through the telescopic tubes 24 on both sides. The third electric push rods 21 on both sides will also be driven to slide on the second slide rail 19. After cleaning, the electric slide rails 13 and the third electric push rods 21 are closed and reset. Then the dust collection parts 25 on both sides are twisted clockwise to take them out. Then the two dust collection parts 25 are cleaned. Then the two dust collection parts 25 are twisted counterclockwise towards the air pumps 23 on both sides to reset them.

[0039] The operation controller 1 activates the electric slide rail 13 to move the ultrasonic transmitters 4 in a direction away from each other. A specified distance is input, causing the two ultrasonic transmitters 4 to move a certain distance away from each other. Simultaneously, the indicator marks 15 on both sides move synchronously. The operator can confirm the measurement by checking the scale reading on the frame 12 indicated by the indicator marks 15. Then, Vaseline is applied to the bottom of the two ultrasonic transmitters 4, and the two first electric push rods 8 are activated to reset the ultrasonic transmitters 4, ensuring they are flush with the ground. The operation controller 1 then instructs the ultrasonic transmitters 4 to perform measurements. The controller 1 is connected via connector 2 and transmission line 3. After the ultrasonic transmitter 4 is connected for measurement and the measurement data is generated and recorded, the first electric push rod 8 is activated to move the ultrasonic transmitter 4 upward. The specified interval is input again, and the controller 1 is activated to start the electric slide rail 13 to move the ultrasonic transmitter 4 a certain distance away from each other. Then the first electric push rod 8 is activated again to make the ultrasonic transmitter 4 fit tightly against the ground. The three data points are measured in this way. Then the crack depth is calculated according to the principle of triangle structure. After the Vaseline is used up, the cover 27 can be opened and the Vaseline can be placed in the placement slot 26. Then the cover 27 can be closed for easy use of Vaseline next time.

[0040] like Figure 10 and Figure 11As shown, it also includes a portable handle 29. The portable handle 29 is slidably connected to the rear side of the frame 12. The operator can pull out the portable handle 29 and then lift and carry the entire device.

[0041] After the crack inspection is completed, when it is necessary to take the device away, the portable handle 29 can be pulled upwards to pull it out, and then the entire device can be lifted off the ground and moved by the portable handle 29, making it easy to carry.

[0042] The above embodiments are provided for those skilled in the art to implement or use the present invention. Those skilled in the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention. Therefore, the protection scope of the present invention is not limited to the above embodiments, but should be the maximum scope that conforms to the innovative features mentioned in the claims.
