Description

Technical Field

[0001] The invention belongs to the technical field of building detection, and in particular relates to a wall detection device for construction engineering. Background Art

[0002] The main functions of building walls are to bear loads, divide spaces, and provide thermal insulation. During the inspection process, measuring whether the wall is tilted is a very important step. The verticality of the wall is related to the wall's load-bearing capacity and its stability. Most of the existing verticality measuring devices use a plumb line to measure the wall's natural verticality under the action of gravity. Some also use mutually perpendicular rods to measure the verticality of the wall. These are measured by workers directly holding the wall, and the measurement accuracy is low. Large errors may occur, affecting the measurement results, and there may also be potential safety hazards. At the same time, if there are some impurities or uneven areas on the wall, it will also affect the measurement results. At the same time, the existing measuring devices cannot lock the uneven position of the wall.

[0003] Moreover, some walls will develop cracks after being used for a period of time. Wall cracks are a common form of damage in buildings. As an initial damage, timely repair or restoration of cracks can reduce safety hazards. When cracks appear in the wall and need to be detected, the measurement personnel usually move along the wall to search for different crack locations for subsequent repairs. However, this method requires the measurement personnel to always remain in a high position, and the physical safety of the measurement personnel cannot be guaranteed. In addition, the edges of the cracks in the wall are often embedded with accumulated dust and debris, which makes the cracks inaccurately measured during the measurement process, affecting the detection effect of the cracks.

[0032] When cleaning the wall and detecting cracks in the wall: When detecting the verticality of the wall, first move the device to the position where the extrusion piece 22 is close to the wall but not in contact with the wall, then adjust the distance between the measuring pieces 11 according to the height of the wall, and the motor 33 drives the rotating roller 8 to rotate, and the rotating roller 8 drives the limiting groove 15, the limiting groove 2, the limiting groove 3, the limiting groove 13 and the limiting groove 4 12 thereon to rotate, and the limiting groove 15, the limiting groove 2, the limiting groove 3, the limiting groove 13 and the limiting groove 4 12 drive the internal insertion rod 17, and the insertion rod 17 moves along the trajectory of the limiting groove 15, the limiting groove 2, the limiting groove 3, the limiting groove 13 and the limiting groove 4 12, and at the same time, the limiting rod Under the action of one 10, the insertion rod 17 can only move up and down along the limit rod one 10, the insertion rod 17 drives the mounting seat 16 to move, and the mounting seat 16 drives the second pressure plate 39 to move towards the direction close to the first pressure plate 38, and the second pressure plate 39 squeezes the extrusion bag 40 between the first pressure plate 38, and the gas in the extrusion bag 40 enters the ventilation cavity 41 connected thereto through the connecting pipe 42, and the gas is transported to different detection plates 36 through the elastic tube 45, and the gas in the detection plate 36 is sprayed onto the wall surface through the outlet hole 44, and the impurities on the wall surface are cleaned, and then the crack detection device 43 is used to realize the crack detection of the wall.

[0033] Check the verticality of the wall: After detecting the cracks in the wall, the distance between the measuring pieces 11 has been adjusted to facilitate the detection of positions at different heights of the wall. The equipment is moved so that the extrusion piece 22 fits against the wall. The wall applies a reaction force to the extrusion piece 22. The extrusion piece 22 drives the measuring rod 21. The measuring rod 21 squeezes the spring 20. The spring 20 squeezes the pressure sensor 19. The multiple pressure values ​​on the measuring component 3 are transmitted to the controller. The controller can judge whether the wall is vertical and whether there are uneven positions on the wall according to the values: If the difference between the values ​​is small, it is considered that the wall is vertically set and there is no uneven position; If most of the values ​​are similar and only a few have large deviations, the wall is vertically set but has uneven areas. If a few of the values ​​are small, there are concave areas on the wall. If a few of the values ​​are large, there are convex areas on the wall. If most of the values ​​decrease or increase from top to bottom, the wall at that location is tilted.
