Description

Technical Field

[0001] The present application relates to the technical field of detection devices, and more specifically, to a device for detecting cracks in building exterior walls. Background Art

[0002] Wall cracks are cracks that occur in the wall part of a building structure. According to the different materials of the materials themselves, they can be divided into concrete wall cracks, brick wall cracks, new partition board cracks and cracks caused by walls of different materials. When the wall cracks are more serious, it will have a greater impact on the stability of the building. Therefore, crack detection devices are needed to detect wall cracks in daily building maintenance.

[0003] The document with prior art announcement number CN220379276U provides a wall crack detection device, which rotates the active sprocket by manually rotating the handle, and the driven sprocket rotates under the drive of the chain, causing the screw to rotate. The detector moves in the vertical direction under the action of the screw and the round rod until the detector moves to a suitable height to detect cracks in the wall. Since the detector is light in weight, the process of manually rotating the handle is not laborious, and the device can be used without an external power supply, and has a wider applicability.

[0004] Although the device has many beneficial effects, the following problems still exist: when detecting cracks on the exterior wall of a building, the detection instrument needs to be attached to the wall. However, when attaching the detection instrument to the wall, the above-mentioned device needs to move the entire device, which can easily cause the staff to use too much force and cause the detection instrument to suddenly collide with the wall and be damaged, which can easily reduce the protective performance of the detection instrument. In view of this, we propose a device for detecting cracks in the exterior wall of a building. Utility Model Content

When inspecting the exterior walls of buildings, it is possible to prevent the staff from using too much force, causing the crack detector body to suddenly collide with the wall and be damaged, thereby facilitating the improvement of the technical effect of the protective performance of the crack detector body.

[0016] Optionally, a mounting ring is provided on the outer fixing sleeve of the support frame, and the mounting ring is connected to the connecting plate through a threaded rod, so that it is convenient for staff to disassemble and assemble the support frame and the crack detector body.

A support frame 5 is provided on one side of the connecting plate 4, and a crack detector body 6 is installed on one side of the support frame 5. A displacement mechanism 3 is provided on the top of the bottom plate 1 to facilitate pushing the crack detector body 6 to move;

[0029] The displacement mechanism 3 includes a slider 31. A slide groove is provided at the top of the base plate 1. The slider 31 is slidably connected in the slide groove. The top of the slider 31 is fixedly connected to the bottom of the support plate 9. A spring 33 is fixedly connected to one side of the slider 31. One end of the spring 33 is fixedly connected to one side of the inner wall of the slide groove, thereby preventing the crack detector body 6 from colliding with the exterior wall of the building and being damaged due to excessive force.

[0030] Reference Figure 2 and Figure 3 A cross bar 32 is fixedly connected in the slide groove, and the slider 31 is slidably sleeved in the slide groove, thereby preventing the slider 31 from escaping from the slide groove.

[0031] Reference Figure 2 and Figure 3 The cross bar 32 is cylindrical and is fixed in the slide groove by welding, so that it is convenient to fix the cross bar 32 in the slide groove and also convenient to sleeve the slider 31 on the outside of the cross bar 32.

[0032] Reference Figure 2 and Figure 3 A push plate 34 is fixedly connected to one side of the support plate 9, and the cross section of the push plate 34 is L-shaped, so that it is convenient for the staff to stand at a position away from the wall to push the support plate 9 for displacement.

[0033] Reference Figure 3 The lifting device 2 includes a motor, a screw rod, a screw sleeve, a sliding rod and a limit plate. The motor is installed on one side of the top of the support plate 9. The motor is connected to an external controller and a power supply. It is a prior art and will not be described in detail here. The screw rod is fixedly connected to the top of the output shaft of the motor, the sliding rod is fixedly connected to the other side of the top of the support plate 9, the limit plate is fixedly connected to the sliding rod and the top of the screw rod, the connecting plate 4 is slidably sleeved on the outside of the sliding rod, and the connecting plate 4 is threadedly sleeved on the outside of the screw rod, so as to facilitate the staff to adjust the height of the connecting plate 4.

[0034] Reference Figure 1 Universal wheels are installed at the four corners of the bottom of the base plate 1 to facilitate the staff to move the base plate 1.

[0035] Reference Figure 1 and Figure 2 Baffles 35 are fixedly connected to both sides of the top of the bottom plate 1, and the cross-section of the baffle 35 is L-shaped, so as to facilitate blocking the support plate 9.

[0036] Reference Figure 2A mounting ring 7 is provided on the outer fixed sleeve of the support frame 5, and the mounting ring 7 is connected to the connecting plate 4 through a threaded rod 8, so that the staff can disassemble and assemble the support frame 5 and the crack detector body 6 conveniently.

[0037] The implementation principle of a building exterior wall crack detection device in an embodiment of the present application is as follows: when it is necessary to detect cracks on the building exterior wall, the staff can push the bottom plate 1 to abut against the wall of the exterior wall. At this time, the crack detector body 6 has no contact with the wall. Then the staff can push the push plate 34 to drive the support plate 9 to move. The movement of the support plate 9 can drive the slider 31 to move. The movement of the slider 31 can pull the spring 33, so that there is resistance to the movement of the support plate 9. The movement of the support plate 9 can drive the connecting plate 4 to move through the lifting device 2. The movement of the connecting plate 4 can drive the support frame 5 and the crack detector body 6 to move, thereby ensuring that the crack detector body 6 moves slowly, thereby preventing the staff from using too much force and causing the crack detector body 6 to collide with the wall and be damaged. At the same time, when the support plate 9 moves to abut against the baffle 35, the crack detector body 6 can be just abutted against the wall, further improving the protection performance of the crack detector body 6.

[0038] The embodiment of the present application provides a device for detecting cracks in the exterior wall of a building. By setting a displacement mechanism 3, when detecting the exterior wall of the building, it can prevent the staff from using too much force so that the crack detector body 6 directly collides with the wall and is damaged, thereby facilitating improving the protection performance of the crack detector body 6.
