Description

TECHNICAL FIELD

[0001] The utility model belongs to detection device technical field, and specifically relates to a building material thickness detection device. BACKGROUND

[0002] In order to ensure the safety, functionality of building and promote the overall quality and service life of building, it is necessary to detect building material, and the thickness detection of building material is particularly important.

[0003] The Chinese patent with publication number CN220230379U discloses a building material thickness detection device, which comprises a rack, a lower cross displacement assembly, an upper cross displacement assembly, a lower measuring lifting head, an upper measuring lifting head and a clamping assembly. The building material to be detected is clamped from both sides by the clamping assembly, the upper measuring lifting head and the lower measuring lifting head are driven to displace by the upper cross displacement assembly and the lower cross displacement assembly, the displacement positions of the upper measuring lifting head and the lower measuring lifting head are consistent, and the two are ensured to be on the same perpendicular line during detection, and then the thickness of the building material is detected by the opposite movement of the upper measuring lifting head and the lower measuring lifting head. When other points need to be detected, the displacement is continued by the upper cross displacement assembly and the lower cross displacement assembly. Compared with the prior art, the device can move more flexibly and detect the thickness of each point of the building material, and the detection method of the upper measuring lifting head cooperating with the lower measuring lifting head is more accurate.

[0004] However, in actual use, the surface of the building material may be uneven, and when the detection head is controlled to move by the cross displacement assembly, the detection head needs to displace vertically to make room for the convex part of the building material surface and fit the concave part of the building material surface, otherwise the detection head may be damaged or cannot fit the surface of the building material. In the above-mentioned scheme, the height of the detection head needs to be changed frequently when the detection position of the building material is changed, which is relatively cumbersome and not conducive to actual use.
