Description

Technical Field

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

[0002] Concrete is one of the most important and widely used building materials in construction projects. Its quality directly affects the safety of the entire building structure. Strengthening the monitoring and testing of concrete quality and ensuring and improving concrete quality are important issues in construction projects today. There are many reasons for concrete cracks, especially during the construction process. These include improper construction leading to failure to compact the concrete, temperature deformation and drying shrinkage during construction, early construction overload, and stress damage to the concrete after it bears load. All of these can lead to the formation of cracks in the later stages of concrete. Some cracks cannot be directly identified by the naked eye and are hidden inside the concrete layer. Therefore, it is very important and necessary to use concrete crack detection devices to detect the depth and direction of cracks.

[0003] Existing patent CN213091561U discloses a concrete crack detection device, including a detection vehicle and a main control board mounted on the vehicle. An ultrasonic probe is installed on the vehicle and connected to the main control board. The detection vehicle includes a support panel with a first detection hole. Longitudinal moving devices are installed on both sides of the first detection hole, and longitudinal moving plates slide on these devices. A second detection hole is located on each longitudinal moving plate, with lateral moving devices installed on both sides. Lateral moving plates slide on these devices, and cylinders are mounted on the lateral moving plates. The extension rods of these cylinders are connected to the ultrasonic probe. This device is vehicle-mounted, making it convenient for people to move the equipment to detect cracks in the ground. When using ultrasound to detect cracks, the detection accuracy is high. The ultrasonic probe can move laterally or longitudinally, exhibiting high flexibility and the ability to automatically move to cracked surfaces for precise measurement.

[0004] The existing technology has the following problems:

[0005] 1. Existing concrete crack detection devices do not have dust removal capabilities. This means that before the device can detect cracks in the ground, manual cleaning of the dust around the cracks is required, which not only wastes labor but also reduces detection efficiency and fails to meet the usage requirements.

[0006] 2. Existing concrete crack detection devices do not have a horizontal adjustment function. This makes it easy for inspectors to make errors in the detection results when the device is not in a horizontal position, which reduces the accuracy of the detection and makes it less practical. Utility Model Content

[0008] To achieve the above objectives, the present invention provides the following technical solution: a concrete crack detection device, comprising a frame, a horizontal adjustment component provided on one side of the bottom of the frame, a moving wheel provided at the bottom end of the horizontal adjustment component, a detector main unit provided on one side of the top of the frame, a detector head provided in the middle of the bottom of the detector main unit, and a dust removal component provided on the other side of the top of the frame.

[0009] The dust removal assembly includes a dust removal box, a filter screen is installed at the top inside the dust removal box, a collection box is installed at the bottom inside the dust removal box, a fan is installed in the middle of the top of the dust removal box, a suction pipe is installed in the middle of one side of the dust removal box, a suction hood is installed at the bottom of the suction pipe, a motor is installed in the middle of the top of the suction hood, an electric telescopic rod is installed at the output end of the motor, and a cleaning brush is installed at the bottom of the electric telescopic rod.

[0010] As a preferred technical solution of this utility model, the horizontal adjustment component includes a mounting plate, bolts, an adjusting cylinder, a screw, an adjusting seat, and anti-slip particles. A bolt is provided on one side of the bottom of the mounting plate. Threaded holes adapted to the bolt size are provided on both the mounting plate and the frame. An adjusting cylinder is provided in the middle of the bottom of the mounting plate. A screw is provided inside the adjusting cylinder. An adjusting seat is provided at the bottom end of the screw. Anti-slip particles are provided on the outer surface of the adjusting seat.

[0011] As a preferred embodiment of this utility model, the outer surface of the screw is threadedly connected to an adjusting cylinder, and the bottom end of the screw is fixedly connected to an adjusting seat. There are four sets of adjusting seats, and the four sets of adjusting seats are arranged in a rectangular pattern.

[0012] As a preferred technical solution of this utility model, the anti-slip particles are arranged in a hemispherical shape, the anti-slip particles are made of rubber, the number of anti-slip particles is several groups, and the anti-slip particles are arranged in a ring array on the adjustment seat.

[0013] In a preferred embodiment of this invention, the filter screen is fixedly installed on the dust collection box, and the size of the filter screen is adapted to the size of the dust collection box.

[0014] As a preferred embodiment of this utility model, the top end of the suction pipe is fixedly connected to a dust collection box, and the bottom end of the suction pipe is fixedly connected to a dust collection hood. The dust collection box, the suction pipe, and the dust collection hood are arranged in a continuous manner.

[0015] As a preferred embodiment of this utility model, a motor is fixedly connected to the top of the electric telescopic rod, and a cleaning brush is fixedly connected to the bottom of the electric telescopic rod. The size of the cleaning brush is adapted to the size of the dust collection hood.

[0016] Compared with the prior art, the present invention provides a concrete crack detection device, which has the following beneficial effects:

[0017] 1. This concrete crack detection device comprises a dust collection box, a filter screen, a collection box, a fan, a suction pipe, a suction hood, a motor, an electric telescopic rod, and a cleaning brush. Before detecting cracks in the ground, the motor is started to rotate the electric telescopic rod, causing the cleaning brush to sweep away dust around the cracks. Then, the fan is started to expel air from the dust collection box, allowing the suction hood to collect the fine dust particles generated by the cleaning brush. These particles are then collected in the dust collection box through the suction pipe and settled into the collection box. Simultaneously, the filter screen filters out fine dust particles from the air, preventing them from being expelled by the fan, thus improving the dust removal efficiency of the device. This design enables the device to perform dust removal, avoiding the need for manual cleaning of dust around the cracks before detection, and meeting usage requirements.

[0018] 2. This concrete crack detection device, by setting up an installation plate, bolts, an adjusting cylinder, a screw, an adjusting seat, and anti-slip particles, increases the friction between the inspector's hand and the adjusting seat during detection. This allows the inspector to rotate the adjusting seat, causing the screw to rotate and move up and down within the adjusting cylinder, thereby adjusting the device's level. Furthermore, when the leveling component is damaged, it can be quickly replaced through the cooperation of the installation plate and bolts. This design enables the device to have a leveling function, avoiding errors in the detection results caused by the device not being level during detection, thus improving the accuracy of the detection and making it highly practical.

[0027] In this embodiment, the horizontal adjustment component 2 includes a mounting plate 201, bolts 202, an adjusting cylinder 203, a screw 204, an adjusting seat 205, and anti-slip particles 206. A bolt 202 is provided on one side of the bottom of the mounting plate 201. Both the mounting plate 201 and the frame 1 are provided with threaded holes that are compatible with the size of the bolts 202. An adjusting cylinder 203 is provided in the middle of the bottom of the mounting plate 201. A screw 204 is provided inside the adjusting cylinder 203. An adjusting seat 205 is provided at the bottom end of the screw 204. Anti-slip particles 206 are provided on the outer surface of the adjusting seat 205.

[0028] Specifically, when the leveling component 2 is damaged, it can be quickly replaced by the cooperation of the mounting plate 201 and the bolt 202.

[0029] In this embodiment, the outer surface of the screw 204 is threadedly connected to the adjusting cylinder 203, and the bottom end of the screw 204 is fixedly connected to the adjusting seat 205. There are four sets of adjusting seats 205, and the four sets of adjusting seats 205 are arranged in a rectangular shape.

[0030] Specifically, by rotating the adjusting seat 205, the screw 204 is driven to rotate, causing it to move up and down inside the adjusting cylinder 203, thereby adjusting the device horizontally;

[0031] In this embodiment, the anti-slip particles 206 are generally hemispherical, and the anti-slip particles 206 are made of rubber. There are several groups of anti-slip particles 206, and the anti-slip particles 206 are arranged in a ring array on the adjusting seat 205.

[0032] Specifically, the anti-slip particles 206 increase the friction between the inspector's hand and the adjusting seat 205, so that the inspector can rotate the adjusting seat 205 more easily;

[0033] In this embodiment, the filter 602 is fixedly installed on the dust collection box 601, and the size of the filter 602 is adapted to the size of the dust collection box 601.

[0034] Specifically, the filter 602 filters out fine dust particles in the dust collection box 601, preventing them from being discharged by the fan 604.

[0035] In this embodiment, the top end of the suction pipe 605 is fixedly connected to the dust collection box 601, and the bottom end of the suction pipe 605 is fixedly connected to the dust collection hood 606. The dust collection box 601, the suction pipe 605 and the dust collection hood 606 are arranged in a through manner.

[0036] Specifically, the dust suction hood 606 is used to suck up the fine dust particles generated by the cleaning brush 609 during cleaning, and the dust is collected into the dust collection box 601 through the suction pipe 605;

[0037] In this embodiment, the top end of the electric telescopic rod 608 is fixedly connected to the motor 607, and the bottom end of the electric telescopic rod 608 is fixedly connected to the cleaning brush disc 609. The size of the cleaning brush disc 609 is adapted to the size of the dust hood 606.

[0038] Specifically, the electric telescopic rod 608 is rotated by the motor 607, which causes the cleaning brush 609 to sweep the dust around the cracks in the ground.

[0039] The working principle and usage process of this utility model are as follows: Before detecting ground cracks, the motor 607 in the dust removal component 6 is activated, which drives the electric telescopic rod 608 on the cleaning brush 609 to rotate, thereby allowing the cleaning brush 609 to sweep the dust around the ground cracks. Then, the fan 604 is activated to discharge the airflow from the dust collection box 601, which in turn allows the dust suction hood 606 to suck up the fine dust particles generated by the cleaning brush 609 during cleaning. These particles are then collected into the dust collection box 601 through the suction pipe 605, and finally settle into the collection box 603 for cleaning. Fine dust particles in the dust collection box 601 are filtered by the filter screen 602 to prevent them from being discharged by the fan 604, thus improving the dust removal effect of the device. During testing, the anti-slip particles 206 increase the friction between the tester's hand and the adjusting seat 205 in the leveling component 2, so that the tester can rotate the adjusting seat 205 to drive the screw 204 to rotate, causing it to move up and down inside the adjusting cylinder 203, thereby adjusting the level of the device. At the same time, when the leveling component 2 is damaged, it can be quickly replaced by the cooperation of the mounting plate 201 and the bolt 202.

[0040] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
