DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] When implementing: Figure 1-4As shown, a crack detection device for a housing construction project comprises: a moving seat 1, an inner wall of the moving seat 1 is fixedly connected to a first servo motor 3, a top end of the moving seat 1 is fixedly connected to a screw rod 2, an output shaft of the first servo motor 3 is fixedly connected to the bottom end of the screw rod 2, and a placement table 4 is threadedly connected to the surface of the screw rod 2; an adjustment mechanism 5, the adjustment mechanism 5 is arranged at the bottom of the placement table 4; wherein, the adjustment mechanism 5 comprises a mounting plate 51 hinged to the bottom end of the placement table 4, a crack detector 52 is arranged on one side of the mounting plate 51, a surface of the mounting plate 51 is provided with annularly distributed limiting holes 510, the top end of the placement table 4 is slidably connected to a limiting frame 511, the lower end of the surface of the limiting frame 511 passes through the placement table 4 and is clamped to the inner wall of one of the limiting holes 510, and a spring 512 is fixedly connected to the opposite end of the limiting frame 511 and the placement table 4.

[0025] Two connecting wires are fixedly connected to one side of the crack detector 52, and a detection probe is fixedly connected to the other end of the connecting wire. The bottom of the limit frame 511 is fixedly connected to a first magnetic block, and the top of the placement table 4 is fixedly connected to a second magnetic block. The bottom of the first magnetic block and the top of the second magnetic block are attracted to each other by their opposite poles. The first magnetic block and the second magnetic block ensure the stability of the limit frame 511 in the mounting plate 51.

[0026] When crack detection is required for the wall of a house, the limit frame 511 is pulled upward to make the lower end of the surface of the limit frame 511 away from the corresponding limit hole 510, and the mounting plate 51 is pushed to rotate at an angle, so that the mounting plate 51 drives the crack detector 52 to rotate to a suitable observation position, and the limit frame 511 is loosened. Because the limit frame 511 is a rubber component, the elastic force of the spring 512 drives the limit frame 511 to move downward and stably engage in the corresponding limit hole 510, and the mounting plate 51 is positioned. At this time, the first servo motor 3 and the crack detector 52 are manually turned on, and the output shaft of the first servo motor 3 rotates to drive the screw rod 2 to rotate, and the screw rod 2 rotates to drive the placement table 4 to move up to a suitable position, and the first servo motor 3 is manually turned off, and the moving seat 1 is pushed, so that the detection probe on the crack detector 52 is pressed against the wall of the house to detect the cracks inside the wall structure through the ultrasonic reflection principle, and the detection data is transmitted to the crack detector 52 through the detection probe for display. The detection personnel can see the detection data on the crack detector 52 to know the crack situation of the wall, and then make subsequent processing work. When no detection is needed, the crack detector 52 is manually turned off.

[0027] like Figure 3-4As shown, the bottom end of the placement table 4 is fixedly connected to a slide frame 57, and the inner wall of the slide frame 57 is slidably connected to two mounting blocks 58, one side of the mounting block 58 is clamped with a rubber sleeve 59, the inner wall of the slide frame 57 is rotatably connected to a bidirectional lead screw 515, the inner wall of the mounting block 58 is threadedly connected to the surface of the bidirectional lead screw 515, one side of the slide frame 57 is fixedly connected to a second servo motor 513, the output shaft of the second servo motor 513 is fixedly connected to one end of the bidirectional lead screw 515, the top of the mounting block 58 is threadedly connected to a screw, and the lower end of the surface of the screw is threadedly connected to the inner wall of the rubber sleeve 59, and the mounting plate 51 Two clamping frames 53 are slidably connected to the inner side, and soft pads are fixedly connected to the opposite sides of the two clamping frames 53. A movable block 54 is slidably connected to the inner side of the mounting plate 51. Two movable holes 55 are opened on one side of the movable block 54. The surface of the clamping frame 53 is slidably connected to the inner wall of the movable hole 55. A screw 56 is threadedly connected to the inner wall of the mounting plate 51. The top of the screw 56 is rotatably connected to the bottom of the movable block 54. The surface of the limit frame 511 is a rubber component. A guide rod 514 is fixedly connected to the inner side of the mounting plate 51, and the inner wall of the movable block 54 is slidably connected to the surface of the guide rod 514.

[0028] When the crack detection device detects cracks on a wall at a higher position, the crack detector 52 is placed on the mounting plate 51, the connecting line and the detection probe are passed through the mounting plate 51, the screw 56 is rotated, and the screw 56 rotates and moves downward in the mounting plate 51 to drive the movable block 54 and the movable hole 55 to move downward, and the two movable holes 55 move downward at the same time to drive the two clamping frames 53 to approach each other, so that the soft pad on the clamping frame 53 contacts the side of the crack detector 52, and the rotation of the screw 56 is stopped, so that the crack detector 52 is stably installed on the mounting plate 51, and the detection probe is clamped on the inner side of the rubber sleeve 59. At this time, the rubber sleeve 59 is clamped on the mounting block 58, and the rubber sleeve 59 is fixed on the mounting block 58 by screws, and the second servo motor 513 is manually turned on, and the output shaft of the second servo motor 513 rotates to drive the bidirectional lead screw 515 to rotate, and the bidirectional lead screw 515 rotates through the mounting block 58 and the rubber sleeve 59 to drive the detection probe to move to a suitable position, and the second servo motor 513 is manually turned off.

[0029] A detection method for a crack detection device for a housing construction project: pull the limit frame 511 upward to make the lower end of the surface of the limit frame 511 away from the corresponding limit hole 510, push the mounting plate 51 to rotate at an angle, so that the mounting plate 51 drives the crack detector 52 to rotate to a suitable observation position, loosen the limit frame 511, and the elastic force of the spring 512 drives the limit frame 511 to move downward and be connected in the corresponding limit hole 510 to position the mounting plate 51, then manually start the first servo motor 3 and the crack detector 52, the output shaft of the first servo motor 3 rotates to drive the screw rod 2 to rotate, and the screw rod 2 rotates to drive the placement table 4 to move up to a suitable position, manually close the first servo motor 3, push the moving seat 1, so that the detection probe on the crack detector 52 hits the wall of the house, and detects the cracks inside the wall structure through the ultrasonic reflection principle, and the detection data is transmitted to the crack detector 52 through the detection probe for display, and the detection personnel can know the crack situation of the wall by observing the detection data on the crack detector 52, and then make subsequent processing work.

[0030] It should be noted that the first magnetic block, the second magnetic block, the first servo motor 3, the crack detector 52, the second servo motor 513, the spring 512, etc. in the above description are all relatively mature devices in the existing technology. The specific models can be selected according to actual needs. At the same time, the first servo motor 3, the crack detector 52, and the second servo motor 513 can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0031] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
