Description

Technical Field

[0001] The present invention relates to the technical field of hollowing detection, and in particular to an intelligent building hollowing detection device and a detection method thereof. Background Art

[0002] Hollowing is caused by the presence of air in the original masonry and the powder layer. When testing, use a hollowing hammer or a hard object to tap the plaster layer and the leveling layer. If a thud is heard, it is a hollowing phenomenon. "Hollowing" in house quality generally refers to the hollowing phenomenon between the floor, wall, and ceiling finishing layer (plastering or pasting tiles) and the structural layer (concrete or brick wall) of the house due to loose bonding and adhesion. It is commonly known as "two layers of skin".

[0003] The existing method of detecting hollow walls in some buildings usually involves workers manually tapping the wall with tools such as sticks to identify the location of the wall defects. This method has errors, and workers cannot tap all positions of the wall, but only tap randomly observed parts for detection, which may result in missed detections. In addition, the human ear becomes fatigued after listening to sounds for a long time, and cannot accurately analyze the sounds after tapping. Summary of the Invention

[0004] The purpose of this section is to summarize some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the abstract and title of this application to avoid obscuring the purpose of this section, the abstract and the title of the invention, and such simplifications or omissions should not be used to limit the scope of the present invention.

[0019] Step 1: Measure and inspect the wall width and height, prepare a sufficient number of connection boxes according to the wall width, then remove the structure of the mobile unit, attach the card block to the top of the outer wall, and then release the toothed bar from the reel to the ground. Then, pass the toothed bar through the power box or connection box, and then fix the metal bar and the limit block with screws;

[0025] It is necessary to place the device on the ground by selecting the correct number of connection boxes, and then drive the connection box to place the second card plate to the left, then connect the power box and multiple connection boxes, drive the second card plate with the connection box to insert into the connection box on the left, and then drive the threaded rod through the connection plate to insert into the interior of the connection box, and then fix it by tightening the nut, then move the device to the position to be tested, place the two fixing columns in front of the wall according to the position of the protective plate, and then connect them through the protective plate inside the first card plate, then connect the first card plate and the third card plate, and then drive the threaded rod through the connection plate to insert into the interior of the first card plate and the third card plate to fix them, and the structural setting of the first card plate and the third card plate allows the auxiliary device to move upward stably, thereby maintaining the stability of the device during work, so that the accuracy of the detection results is improved;

[0026] 3. During use, the gear is driven to rotate by the rotating shaft or the first connecting shaft, so that the gear drives the device to move upward under the cooperation between the gear and the rack. During the movement, the second connecting shaft and the extrusion wheel cooperate to squeeze the rack, so that the rack and the gear fit tightly, preventing the rack and the gear from falling off during the movement.

Then, the structure of the mobile unit (300) is taken out, and the clamping block (302) is clamped on the top of the outer wall. Then, the toothed bar (301) is released from the reel to the ground position, and then the toothed bar (301) is passed through the power box (101) or the connection box (102), and then the metal bar (306) and the limit block (307) are fixed by screws (308); Step 2: Connect the protective plate (108) between the first card plate (103) and the third card plate (109), movably connect the two protective plates (108) with the fixing column, then assemble the power box (101) and the connection box (102), insert the connection plate (104) with the protective pad (107) into the power box (101) and the inside of the power box (101), and then fix them with the threaded rod (106), and then fix the first card plate (103), the third card plate (109) and the power box (101) or the connection box (102); Step 3: Finally, the motor (201) inside the power box (101) is started, and the motor (201) drives the rotating shaft (202) to rotate. The rotating shaft (202) drives the first connecting shaft (204) to rotate through the clamping column (203), and the rotating disk (205) is driven to rotate through the rotating shaft (202) or the push plate (206), so that the rotating disk (205) drives the push plate (206) to move, thereby pushing the slide plate (2011) to move and hit the wall. During the hitting process, the gear (305) is driven to rotate through the rotating shaft (202) or the first connecting shaft (204), and the gear (305) and the tooth bar (301) cooperate to drive the device to move upward, thereby detecting the building. The hitting sound is recorded by the analyzer (208) to detect abnormal sound; Step 4: Device detection is completed. By disassembling the connection structure of the connection plate (104), the device is separated and the test is completed.
