Description

Technical Field

[0001] The utility model relates to the technical field of exterior wall crack detection, in particular to a building exterior wall crack detection device. Background Art

[0002] With the continuous development and progress of modern construction engineering technology, the requirements for building quality are getting higher and higher, especially to reduce harmful cracks on the exterior walls of buildings to avoid affecting the durability and applicability of the overall structure. Wall cracks are cracking phenomena caused by the wall part of the building structure. According to the different materials of the materials themselves, they can be divided into concrete wall cracks, brick masonry wall cracks, new partition board cracks and cracks caused by walls of different materials. When the width of the cracks in the building exceeds a certain limit, they become harmful cracks. The existence of harmful cracks seriously affects the durability and applicability of the structure. When the exterior walls of the building are completed, staff are required to use handheld detectors to inspect the exterior walls to check whether there are any cracks inside the wall.

[0003] In the prior art, crack detection of existing building exterior walls is mostly performed by manually using handheld detectors to detect the wall. This detection method has a high risk factor, a large amount of labor, is prone to omissions, has low work efficiency and low accuracy. Utility Model Content

[0006] By adopting the above technical solution, when in use, the power is turned on, the main body is moved to a suitable distance and then fixed, and the motor is synchronously started by the remote control device to drive the screw rod to rotate. Since the outer threads are in opposite directions, the two sets of telescopic frame bases are moved closer or farther away, thereby driving the telescopic frame to move up and down. When the height is appropriate, the lifting is stopped and maintained;

The detection probes in the detection mechanism are close to the outer wall, and the scanned data is transmitted to the detector for analysis, so as to achieve large-range and precise detection of walls of a certain height.

[0008] Thus, it is convenient, fast, safe, and improves the overall efficiency of crack detection.

[0009] Furthermore, dust-proof curtain brackets are provided on the outer sides of the four weeks of the support plate, and the dust-proof curtain brackets are connected to the main body through a dust-proof curtain.

[0010] By adopting the above technical solution, when the telescopic frame extends, the dust-proof curtain can be evenly unfolded to achieve the dust-proof effect.

[0011] Furthermore, motor fixing brackets are respectively arranged on both sides inside the main body, and the motor fixing brackets play a role in fixing the motor.

[0012] By adopting the above technical solution, the motor can be better fixed to prevent jitter and avoid affecting the use.

[0013] Furthermore, the telescopic frame base and the telescopic frame are movably connected through a rotating shaft, and a bearing is arranged between the telescopic frame base and the rotating shaft.

[0014] By adopting the above technical solution, the wear at the connection between the telescopic frame base and the telescopic frame is reduced.

[0015] Furthermore, the detection mechanism and the detector are electrically connected through an external wire, and the wire is of a spiral telescopic structure.

[0016] By adopting the above technical solution, the cracks on the outer wall can be better detected in real time.

[0017] Furthermore, rollers are provided at the top and bottom of the outer side of the protective shell, and the rollers are connected to the protective shell through a rotating shaft.

[0018] By adopting the above technical solution, when the detection mechanism moves horizontally on the wall surface, it plays a role in protecting the protective shell and the detection probe inside.

[0019] In summary, the utility model mainly has the following beneficial effects: The utility model drives the lead screw to rotate through the rotation of the motor, and controls the two telescopic frame bases to move in opposite directions through the opposite threads on the lead screw. The movement of the telescopic frame base drives the telescopic frame to expand and contract, and the expansion and contraction distance can be easily controlled. Through the cooperation with the detection mechanism, the detector, and the detection probe, the effect of large-area and precise detection of the cracks on the outer wall of the building is achieved, saving time and effort and improving the detection efficiency of the cracks on the outer wall of the building.
