Embodiment Construction
[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0025] Such as Figure 1-5 As shown, a crack detection device for building exterior walls includes a lower casing 1, an upper casing 2, a first rotary sleeve 3, a second rotary sleeve 4, a motor 5, a rotary plate 6 and a crack detector body 7; The lower casing 1 is a cylindrical cavity structure with an open top, and the upper casing 2 is a cylindrical cavity structure with an open bottom. The upper casing 2 and the lower casing 1 are arranged coaxially and at inte...

The invention discloses a building external wall crack detection device. The device comprises a lower shell, an upper shell, a first rotating sleeve, a second rotating sleeve, a motor, a rotating plate and a crack detector body. The motor drives the rotating plate to rotate; a through groove is formed in the rotating plate; a reciprocating screw rod is rotationally connected into the through groove; and the crack detector is meshed with the reciprocating screw rod. The device has the following beneficial effects that during use, the device is fixed on a wall surface through suckers, the motoris then started, the motor drives the rotating plate to rotate in the working process, therefore, the crack detector body detects cracks on the wall body, in the process, a rack drives a gear to rotate once every time the rotating plate rotates by a circle, so that the reciprocating screw rod rotates, the crack detector body is driven to move by a certain distance in the length direction of the rotating plate, all-dimensional measurement of the wall surface in a circular area can be achieved, and the measurement area is remarkably increased.
Description
technical field [0001] The invention relates to the technical field of detection devices for external walls, in particular to a detection device for cracks in external walls of buildings. Background technique [0002] Wall cracks are the cracking phenomenon of the wall part of the building structure. According to the different materials, they can be divided into concrete wall cracks, brick masonry wall cracks, new partition wall cracks and cracks caused by walls of different materials. , the detection of wall cracks is one of the important items in the construction acceptance process, and the detection of wall cracks is generally carried out by crack detectors. [0003] Existing crack detectors are generally hand-held, and workers hold the crack detector to detect cracks on the wall. Workers who hold it for a long time are prone to hand pain. [0004] The patent publication number is: the Chinese patent of CN211263362U discloses a kind of crack detection device of building ...
