House cracks can be mainly divided into two categories: structural cracks and non-structural cracks; non-structural cracks have little effect on the structure of the house, but when larger cracks appear, for safety reasons, a house safety appraisal agency should be commissioned to conduct inspections to ensure the usability of the house.

[0003] The existing method of detecting cracks in houses is usually to manually use the flaw detection head of a handheld crack measuring instrument to detect the cracks. However, cracks on the ceiling of the house require maintenance personnel to climb up to operate, and some cracks are long, requiring repeated adjustment of the position of the escalator for detection, resulting in low detection efficiency; some house crack detection devices are usually large in size and poor in portability, making them difficult to use in conjunction with a crack measuring instrument.

[0004] Therefore, those skilled in the art have proposed a comprehensive crack testing device for house detection to solve the problems raised by the background technology. Utility Model Content

[0023] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0024] Embodiment 1: As shown in the attached Figure 1 To Attachment Figure 5 As shown: the utility model provides a comprehensive crack testing device for house detection, comprising a support frame 1 and a displacement assembly; a through hole 3 is opened on the upper surface of the support frame 1, a lifting column 4 is installed inside the through hole 3, and a positioning assembly for fixing the position of the lifting column 4 is installed between the through hole 3 and the lifting column 4. The lifting column 4 can be stably slid through the through hole 3 to adjust the position of the lifting column 4. The positioning assembly locks and fixes the position of the lifting column 4 to keep the position of the lifting column 4 stable;

[0025] The displacement assembly includes a top frame 6 rotatably mounted on one end of a lifting column 4, a threaded rod 7 rotatably mounted on the inner wall of the top frame 6, a slide seat 8 threadedly engaged with the circumference of the threaded rod 7, a positioning frame 9 fixed to the upper surface of the slide seat 8, and a servo motor 11 mounted on one end of the threaded rod 7; a flaw detection head 10 is mounted on the upper surface of the positioning frame 9; the threaded rod 7 is driven to rotate by the servo motor 11 to realize the position of the slide seat 8, thereby driving the positioning frame 9 and the flaw detection head 10 to slide along the position of the top frame 6.

[0026] The positioning assembly includes a groove 13 with a through hole 3, a return spring 14 connected to the inner wall of the groove 13, a connecting plate 15 installed at one end of the return spring 14, a positioning block 16 fixed to the surface of the connecting plate 15, and a positioning groove 5 opened on the side of the lifting column 4; a pull column 17 is fixedly connected to the other surface of the connecting plate 15, the pull column 17 is located on the inner side of the return spring 14, and the pull column 17 penetrates to the outer side of the groove 13, and a pull plate 18 is installed at one end of the pull column 17; the positioning block 16 is engaged with the positioning groove 5;

[0027] When the position of the lifting column 4 needs to be adjusted, the pull plate 18 is pulled, and the pull plate 18 drives the connecting plate 15 to move through the pull column 17. At this time, the positioning block 16 slides out of the positioning groove 5, and the positioning block 16 releases the limit of the lifting column 4, so that the height of the lifting column 4 can be easily adjusted. When adjusting the height of the lifting column 4, the position of the flaw detection head 10 is aligned with the crack in the roof. After the adjustment is completed, the pull plate 18 is released. At this time, the reset spring 14 is reset, and the connecting plate 15 and the positioning block 16 are popped out, and the positioning block 16 is stuck in the positioning groove 5 to realize the positioning of the lifting column 4.

[0028] A connecting column 601 is fixedly connected to the bottom surface of the top frame 6, and the connecting column 601 is inserted into one end of the lifting column 4, and a tightening knob 602 is installed between the lifting column 4 and the connecting column 601; by adjusting the tightening knob 602, the position of the top frame 6 can be adjusted, which is convenient for detecting different cracks.

[0029] A battery module 12 is installed on the side wall of the top frame 6 . The battery module 12 is electrically connected to the servo motor 11 . The battery module 12 can stably supply power to the servo motor 11 .

[0030] A bracket 20 is fixedly connected to the front end face of the support frame 1, a damping pad 21 is provided at the limit rod of the front end face of the bracket 20, and a support 2 is fixedly installed on the bottom surface of the bracket 20; a crack detector can be placed at the front end of the support frame 1 through the bracket 20, and by connecting with the flaw detection head 10, the condition of cracks inside the house can be quickly determined; conventional crack detectors are hung on the chest of the human body through a strap for observation. Since the crack detector is heavy, it consumes more manual labor and affects the efficiency of crack detection. This method allows staff to work without holding the detector, which greatly improves the detection flexibility and efficiency.

[0031] The bottom surface of the lifting column 4 is fixedly connected with a limit plate 19 , and the limit plate 19 is slidably matched with the inner wall of the support frame 1 .

[0032] As can be seen from the above, when crack detection is required, the support frame 1 is moved to the bottom of the crack, and the top frame 6 is installed at one end of the lifting column 4. The top frame 6 is connected to the support frame 1 through the connecting column 601, and is locked and fixed by the tightening knob 602, and the top frame 6 is placed according to the position where the crack is formed; then the flaw detection head 10 is installed at the positioning frame 9. During installation, the flaw detection head 10 is placed in the two groups of clamping plates 903, and the bidirectional screw 901 is driven to rotate by rotating the turning handle 902, and the bidirectional screw 901 drives the two groups of clamping plates 903 to be symmetrically displaced, so that the flaw detection head 10 is clamped and fixed; the flaw detection head 10 can slide along the crack through the displacement component;

[0033] The height of the lifting column 4 is adjusted by pulling the pull plate 18. After the adjustment is completed, the pull plate 18 is released, and the reset spring 14 is reset, the connecting plate 15 and the positioning block 16 are ejected, and the positioning block 16 is inserted into the positioning groove 5 to realize the positioning of the lifting column 4.

[0034] During the detection process, the servo motor 11 is controlled to work, driving the threaded rod 7 to rotate. The threaded rod 7 is threadedly matched with the slide seat 8, so that the positioning frame 9 slides along the top frame 6, realizing automatic displacement detection of the flaw detection head 10 at a high place. The staff need not climb up to operate, which is safer and more efficient.

[0035] When the device needs to be stored, the lifting column 4 can be stored in the support frame 1 by pulling the pull plate 18 to release the limit of the positioning block 16, and the top frame 6 can be removed. At this time, the device is reduced to the size of the support frame 1, making the device extremely portable and easy to transport and carry.

[0036] Embodiment 2: Based on embodiment 1, the inner wall of the positioning frame 9 is rotatably connected with a bidirectional screw 901 , the bidirectional screw 901 is symmetrically threaded with two sets of clamping plates 903 , and one end of the bidirectional screw 901 is fixedly connected with a turning handle 902 .

[0037] As can be seen from the above, the flaw detection head 10 can be installed through the positioning frame 9. By rotating the handle 902, the bidirectional screw 901 is driven to rotate. The bidirectional screw 901 drives the two sets of clamps 903 to slide symmetrically at the same time, so that the flaw detection head 10 can be stably clamped to prevent the flaw detection head 10 from falling from a height during the detection process.
