[0009] Preferably, one end of a guide column is fixed on the U-shaped plate, and the other end of the guide column passes through the second support plate and is slidably matched with the second support plate.

[0010] Preferably, a support bar for supporting the T-shaped connecting plate is fixedly connected to the upper surface of the mounting plate.

[0016] The object of the present invention is to provide a comprehensive crack testing device for house and real estate detection, which has the following beneficial effects:

[0017] When detecting cracks on the wall of a house, the present solution causes the second driving mechanism to drive the detector to move up and down along the wall, so that the cracks on the wall can be fully detected. When detecting cracks on the ceiling of a house, it is only necessary to cause the second driving mechanism to drive the detector to move upward to the maximum extent.

This not only realizes the automatic adjustment of the angle of the detector and ensures the adjustment efficiency, but also does not require the installation of an additional angle adjustment motor, thereby reducing procurement costs and subsequent maintenance costs.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0030] Embodiment 1

[0031] See also Figure 1-Figure 9 A comprehensive crack testing device for house and real estate detection provided by an embodiment of the present invention includes a base plate 1, a first shell 2 and a mounting plate 3. The first shell 2 and the mounting plate 3 are connected by a second driving mechanism. Two first support plates 4 are fixedly connected to the upper surface of the mounting plate 3. A rotating roller 5 is rotatably installed between the two first support plates 4. A T-shaped connecting plate 6 is fixedly connected to the outer surface of the rotating roller 5. A detector 7 is fixedly installed on the side of the T-shaped connecting plate 6 away from the rotating roller 5. Two symmetrical right-angle plates 8 are fixedly connected to one side of the first shell 2. The detector 7 is located between the two right-angle plates 8. Two symmetrical gears 17 are fixedly connected to both sides of the rotating roller 5, respectively. A tooth plate 18 adapted to the gear 17 is fixedly connected to the side of the two right-angle plates 8 close to each other, that is, the gear 17 can mesh with the tooth plate 18.

[0032] In order to prevent the mounting plate 3 from interfering with the tooth plate 18 during movement, a first through slot is provided inside the mounting plate 3 for the tooth plate 18 to pass through.

[0033] The detector 7 is a commonly used detector on the market, and its working principle is based on optical principles and image processing technology. The crack image is collected through a lens, and then the image is converted into a digital signal by an optical sensor, and the crack edge information is extracted by image processing technology, and finally the crack width is calculated.

[0034] As a further explanation of this embodiment, a limiting mechanism for limiting the rotating roller 5 is arranged above the mounting plate 3, a third support plate 25 is fixedly connected to the inside of the first shell 2, and a first wedge block 9 corresponding to the limiting mechanism is fixedly connected to the bottom surface of the third support plate 25. There are two limiting mechanisms and two first wedge blocks 9, and the two limiting mechanisms are symmetrical about the center of the mounting plate 3. The two first wedge blocks 9 are symmetrical about the center of the third support plate 25. When the mounting plate 3 moves upward with the gear 17 until it contacts the tooth plate 18, the limiting of the rotating roller 5 is released, and then the gear 17 continues to move up and down, and the tooth plate 18 will drive the gear 17 to rotate. The rotation of the gear 17 can drive the rotating roller 5 and the detector 7 to rotate accordingly. When the mounting plate 3 moves upward to the maximum extent, the detector 7 will rotate to be parallel to the ceiling.

[0035] The limiting mechanism includes a second support plate 10 fixedly connected to the upper surface of the mounting plate 3, one end of a spring 11 is fixedly connected to the side of the second support plate 10 close to the rotating roller 5, and the other end of the spring 11 is fixedly connected to a second wedge block 12 adapted to the first wedge block 9. When the mounting plate 3 drives the second wedge block 12 to move to contact with the first wedge block 9, the mounting plate 3 continues to move upward to allow the first wedge block 9 to squeeze the second wedge block 12 to move away from the rotating roller 5. At the same time, the movement of the second wedge block 12 can compress the spring 11.

[0036] As a further explanation of this embodiment, the outer surface of the second wedge block 12 is fixedly connected with a U-shaped plate 14, and the movement of the second wedge block 12 can drive the U-shaped plate 14 to move accordingly. The side of the U-shaped plate 14 close to the rotating roller 5 is fixedly connected with a limiting column 15, and the interior of the rotating roller 5 is provided with a limiting hole 16 adapted to the limiting column 15, that is, the limiting column 15 can be movably arranged in the limiting hole 16. The movement of the U-shaped plate 14 can drive the limiting column 15 to move accordingly. When the second wedge block 12 is completely moved to the left side of the first wedge block 9, the limiting column 15 will be completely moved out of the limiting hole 16, thereby releasing the limit on the rotating roller 5, and then the mounting plate 3 and the second wedge block 12 continue to move upward to drive the rotating roller 5 and the detector 7 to rotate.

[0037] A guide column 13 is fixedly connected to one side of the U-shaped plate 14 away from the rotating roller 5. An end of the guide column 13 away from the U-shaped plate 14 passes through the second support plate 10 and slidably cooperates with the second support plate 10. By setting the guide column 13, the second wedge block 12 and the U-shaped plate 14 can be prevented from deviating from the direction during movement.

[0038] As a further explanation of this embodiment, a support bar 20 for supporting the T-shaped connecting plate 6 is fixedly connected to the upper surface of the mounting plate 3. After the limiting column 15 is completely moved out from the inside of the limiting hole 16 and the limiting of the rotating roller 5 is released, the support bar 20 can support the T-shaped connecting plate 6 and the detector 7.

[0039] As a further explanation of this embodiment, sliders 19 are rotatably installed at both ends of the rotating roller 5, and the two sliders 19 are respectively slidably connected to the inside of the two right-angle plates 8. Specifically, a sliding groove compatible with the slider 19 is opened inside the right-angle plate 8, and the slider 19 is slidably configured in the sliding groove. Through the cooperation between the slider 19 and the sliding groove, the stability of the mounting plate 3 and the detector 7 during the up and down movement can be improved.

[0040] As a further explanation of the present embodiment, the second driving mechanism includes a second motor 27 fixedly mounted on the upper surface of the third support plate 25, a second threaded rod 26 being coaxially fixed to the output end of the second motor 27, an end of the second threaded rod 26 away from the second motor 27 passes through the third support plate 25 and is rotatably mounted inside the first shell 2, a second threaded block 28 is threadedly connected to the outer surface of the second threaded rod 26, and a bottom surface of the second threaded block 28 is fixedly connected to the upper surface of the mounting plate 3. When the second motor 27 is controlled to rotate forward, the second motor 27 can drive the second threaded rod 26 to rotate forward, and the forward rotation of the second threaded rod 26 can drive the second threaded block 28, the mounting plate 3 and the detector 7 to move upward. When the second motor 27 is controlled to reverse, the second motor 27 can drive the second threaded rod 26 to rotate reversely, and the reverse rotation of the second threaded rod 26 can drive the second threaded block 28, the mounting plate 3 and the detector 7 to move downward.

[0041] When detecting cracks on the wall inside the house, the second driving mechanism can be used to drive the mounting plate 3 and the detector 7 to move up and down along the wall, so that the cracks on the wall can be fully detected. When detecting cracks on the ceiling inside the house, the mounting plate 3 and the detector 7 can be driven to move upward to the maximum extent. During the upward movement of the mounting plate 3 and the detector 7, the mounting plate 3 will first drive the second wedge block 12 to move to contact with the first wedge block 9, and then the mounting plate 3 will continue to move upward to make the first wedge block 9 The second wedge block 12 is squeezed to move away from the rotating roller 5. The movement of the second wedge block 12 can drive the U-shaped plate 14 and the limiting column 15 to move accordingly and compress the spring 11. When the second wedge block 12 is completely moved to the left side of the first wedge block 9, the limiting column 15 will be completely moved out of the limiting hole 16, and the limiting of the rotating roller 5 can be released. At this time, the gear 17 will move to contact with the tooth plate 18, and then the mounting plate 3 and the detector 7 continue to move upward, and the tooth plate 18 will drive the gear 17 to rotate, and the gear 1 The rotation of the U-shaped plate 14 can drive the rotating roller 5 and the detector 7 to rotate accordingly. When the mounting plate 3 moves upward to the maximum extent, the U-shaped plate 14 will move to contact with the third supporting plate 25, and the detector 7 will rotate to be parallel to the ceiling. Then, the ceiling cracks can be detected by the detector 7. After the detection is completed, the second driving mechanism drives the mounting plate 3 and the detector 7 to move downward. When the mounting plate 3 and the detector 7 move downward, the toothed plate 18 will drive the gear 17 and the detector 7 to rotate in the opposite direction. When the mounting plate 3 moves downward, the toothed plate 18 will drive the gear 17 and the detector 7 to rotate in the opposite direction. During the process, under the action of the spring 11, the second wedge block 12 will always press against the first wedge block 9. When the detector 7 rotates to be parallel to the wall again, the gear 17 and the tooth plate 18 are no longer in contact, the first wedge block 9 no longer blocks the second wedge block 12, the limiting column 15 is concentric with the limiting hole 16, and then under the action of the spring 11, one end of the limiting column 15 will be inserted into the limiting hole 16 again, so that the rotating roller 5 and the detector 7 can be limited, and then the cracks on the wall can continue to be detected.

[0042] Embodiment 2

[0044] The bottom plate 1 and the first shell 2 are connected by a first driving mechanism, which includes a second shell 21 fixedly connected to the upper surface of the bottom plate 1, a first threaded rod 22 is rotatably installed inside the second shell 21, a first motor 23 is installed on one side of the second shell 21, an output end of the first motor 23 is fixedly connected to one end of the first threaded rod 22, a first threaded block 24 is threadedly connected to the outer surface of the first threaded rod 22, and the first threaded block 24 is slidably connected to the inside of the second shell 21, and the upper surface of the first threaded block 24 is fixedly connected to the bottom surface of the first shell 2. When the first motor 23 rotates forward, the first motor 23 can drive the first threaded rod 22 to rotate forward, and the forward rotation of the first threaded rod 22 can drive the first threaded block 24, the first shell 2 and the detector 7 to move to the left. When the first motor 23 is controlled to rotate reversely, the first motor 23 can drive the first threaded rod 22 to rotate reversely, and the reverse rotation of the first threaded rod 22 can drive the first threaded block 24, the first shell 2 and the detector 7 to move to the right. When the detector 7 rotates to be parallel to the ceiling, by controlling the first motor 23 to rotate forward and reverse, a comprehensive detection of cracks on the ceiling can be carried out.
