Description

Technical Field

[0001] The invention relates to the technical field of interior decoration, in particular to a hollowing detection machine for ceramic tile floors. Background Art

[0002] With the rapid development of the modern construction industry, the paving quality of floors and walls has become one of the important factors affecting the overall quality of buildings. As a common paving material, the laying quality of floor tiles is directly related to the flatness, aesthetics and service life of the floor. However, in the process of laying floor tiles, due to various reasons (such as improper base treatment, uneven mortar application, incomplete compaction of floor tiles, etc.), floor tiles often become hollow. The hollowing of floor tiles will not only affect the aesthetics and comfort of the floor, but may also cause the floor tiles to loosen, warp or even break, posing a safety hazard to users.

[0003] The Chinese invention patent with publication number: CN113356630A discloses a hollowing treatment device for marble floors. The device is used to detect whether the floor has hollowing phenomenon, and drills a drill bit into the gap between the two floors closest to the hollowing location to fill and repair the hollow area, thereby ensuring that the marble floor can work normally without being damaged.

[0004] At present, the detection of the hollow problem of floor tiles mainly relies on the manual use of a hollow hammer, combined with the knocking sound and experience. Although this method can detect the problem to a certain extent, it is inefficient, inaccurate and easily affected by human factors. At the same time, the drill bit used in the above device to drill into the hollow area for filling and repairing will damage the floor tiles, causing the floor tiles to be destroyed, resulting in the need to replace the floor tiles.

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] like Figures 1 to 4 As shown, a ceramic tile floor hollowing detection machine includes an outer shell 201, ceramic tiles 100, and a closed frame 101. A plurality of movable rollers are arranged on the outer side of the outer shell 201 to control the movement of the device. An inner bracket 202 is also fixedly installed in the outer shell 201. An inner motor 203 is fixedly installed on the inner bracket 202. The inner motor 203 is fixedly connected to the inner wall of the outer shell 201. A plurality of inner rotating shafts 204 are rotatably installed on the inner bracket 202. The inner rotating shaft 204 closest to the inner motor 203 is fixedly connected to the output shaft of the inner motor 203. Cams 205 are respectively arranged on the plurality of inner rotating shafts 204. The states of the cams 205 on the inner rotating shafts 204 are all different. The states of each cam 205 on the inner rotating shaft 204 differ by at least 30 degrees. This is to prevent two-point synchronous detection during multi-point detection. A plurality of belts 206 are also arranged on the inner rotating shaft 204. Power is transmitted between the plurality of inner rotating shafts 204 through the belts 206.

[0026] like Figures 2 to 6As shown, a lower bracket 212 is fixedly installed in the housing 201, and a swing frame 210 is fixedly installed on the lower bracket 212. The swing frame 210 is provided with a moving slot, and a swing spring 209 is fixedly installed on the swing frame 210. A fixed plate 208 is fixedly installed on the other end of the swing spring 209, and a swing rod 207 is fixedly installed on the fixed plate 208. One end of the swing rod 207 is arranged in the housing 201, and the other end of the swing rod 207 is arranged outside the housing 201. The end of the housing 201 is fixedly mounted with a rubber hemisphere, which contacts the outer surface of the cam 205. The swing rod 207 is arranged outside the housing 201 and fixedly mounted with a collision ball head 211, which is made of stainless steel. The lower bracket 212 is also fixedly mounted with a detection and analysis module 213 for collecting the collision sound between the collision ball head 211 and the tile 100. When the detection is performed, the inner shaft 204 in the housing 201 rotates completely, so that all the inner shafts 204 in the housing 201 can be rotated. The cam 205 rotates, thereby squeezing the rubber hemisphere on the swing rod 207. At this time, since the cam 205 is set in a different state in the initial state, the time for each group of cams 205 to drive the swing rod 207 to swing is different. For example, when the leftmost cam 205 drives the swing rod 207 to swing, all the swing rods 207 in the shell 201 will not swing. Only when the swing rod 207 that has completed the swing returns to the initial position, the swing rod 207 in the next position will swing. This prevents the detection and analysis module 213 from collecting inaccurate information. After the swing rod 207 swings, the elastic space required for its swing is limited by the swing spring 209 and the moving groove on the swing frame 210. When the swing spring 209 is squeezed by the swing rod 207, the swing rod 207 will cause the collision ball head 211 to swing, and the collision ball head 211 will hit the tile 100 when it swings. The sound of the tile 100 being hit is collected by the detection and analysis module 213, and then it is detected whether the bottom of the tile 100 is hollow.

[0027] like Figure 1 , Figure 7 , Figure 8 As shown, a storage cylinder 105 for storing filling liquid is fixedly installed on the outer shell 201, and a plurality of side pillars 104 are fixedly installed on the outer side of the storage cylinder 105. An automatically retractable telescopic cylinder 103 is fixedly installed on the side pillar 104. A clamp 102 is rotatably installed on the end of the telescopic cylinder 103 away from the side pillar 104. The telescopic cylinder 103 cooperates with the clamp 102 to clamp the closing frame 101. The closing frame 101 is provided with a material passing hole. The telescopic cylinder 103 can control the closing frame 101 to move up and down, and the closing frame 101 is used to close the space around the tile 100 to prepare for the subsequent filling and repair of the bottom of the tile 100.

[0028] like Figure 1 , Figure 2 and Figure 7 As shown, a main pressure motor 108 is fixedly mounted on the storage cylinder 105, and a main pressure screw 109 is fixedly mounted on the output shaft of the main pressure motor 108. A large pressure plate 107 is slidably mounted in the storage cylinder 105. The storage cylinder 105 and the large pressure plate 107 form a closed chamber, and the closed chamber is used to store fillers. The filler can be epoxy resin glue or modulated cement mortar. The large pressure plate 107 is connected to the main pressure screw 109 by threads. A plug 106 is also provided on the large pressure plate 107. The plug 106 is connected to the large pressure plate 107 by threads. After the plug 106 is rotated, the closed chamber formed by the storage cylinder 105 and the large pressure plate 107 can be opened to facilitate users to add fillers.

[0029] like Figure 1 , Figure 7 , Figure 8 As shown, a pressure cylinder 301 is slidably mounted on the outer wall of the storage cylinder 105, a feed pipe 310 is fixedly mounted on the end of the pressure cylinder 301 close to the tile 100, a delivery pipe 309 is fixedly mounted on the end of the feed pipe 310 away from the pressure cylinder 301, the other end of the delivery pipe 309 is fixedly connected to the storage cylinder 105, the connection between the delivery pipe 309 and the storage cylinder 105 is arranged at the bottom of the closed chamber, an inner narrow tube is arranged inside the feed pipe 310, a feed bracket 313 is slidably mounted on the feed pipe 310, one end of the feed bracket 313 is arranged outside the feed pipe 310, the other end of the feed bracket 313 is arranged inside the feed pipe 310, and the feed bracket 313 is arranged at the feed pipe 310. A feed spring 311 is fixedly installed at one end outside the tube 310, and the other end of the feed spring 311 is fixedly installed on the outer wall of the feed tube 310. The feed bracket 313 is arranged in the feed tube 310 and has a feed plug 312 fixedly installed at one end. The feed plug 312 is in close contact with the inner narrow tube in the feed tube 310 in the initial state. In the initial state, the feed plug 312 closes the inner narrow tube in the feed tube 310. When the filler is pressurized in the storage cylinder 105 and enters the delivery tube 309, the filler will impact the feed plug 312 in the feed tube 310, causing the feed plug 312 to move toward the pressure cylinder 301, thereby opening the closed inner narrow tube to allow the filler to enter the pressure cylinder 301.

[0030] like Figures 7 to 9As shown, the pressure cylinder 301 is provided with a discharge pipe 314 fixedly mounted on one end of the feed pipe 310, and a discharge hole is arranged in the discharge pipe 314. A discharge bracket 317 is slidably mounted on the discharge pipe 314, and one end of the discharge bracket 317 is arranged in the discharge pipe 314. A discharge plug 315 is fixedly mounted on one end of the discharge bracket 317 arranged in the discharge pipe 314, and the discharge plug 315 is in close contact with the discharge hole in the discharge pipe 314. The discharge bracket 317 is arranged on one end outside the discharge pipe 314 and is fixedly installed with a discharge spring 316. The other end of the discharge spring 316 is fixedly connected to the outer wall of the discharge pipe 314. When the filler in the pressure cylinder 301 is subjected to pressure, the filler will rush to the discharge plug 315 in the discharge pipe 314, causing the discharge plug 315 to move away from the closing frame 101, thereby allowing the discharge plug 315 to open the channel of the discharge hole, thereby allowing the filler to flow out of the pressure cylinder 301.

[0031] like Figure 1 and Figures 7 to 9 As shown, an injection needle 319 is slidably mounted on one end of the discharge tube 314 away from the pressure cylinder 301, and the injection needle 319 can pass through the material through hole on the closing frame 101. A limiting ring is fixedly mounted on the outer wall of the injection needle 319, and the limiting ring can contact the closing frame 101 to close the material through hole. A compensation spring 318 is fixedly mounted on the outer wall of the injection needle 319, and the other end of the compensation spring 318 is fixedly mounted on the discharge tube 314. A pressure plate 303 is also slidably mounted on the inner wall of the pressure cylinder 301, and an injection screw 302 is rotatably mounted on the pressure plate 303. The injection screw 302 is rotatably mounted on the pressure plate 303. 02 is connected to the pressure cylinder 301 by threads, a main motor 305 is fixedly installed on the storage cylinder 105, a retractable main telescopic cylinder 304 is fixedly installed on the output shaft of the main motor 305, the moving end of the main telescopic cylinder 304 is fixedly connected to the injection screw 302, a moving motor 306 is also fixedly installed on the storage cylinder 105, a sub-telescopic cylinder 307 is fixedly installed on the output shaft of the moving motor 306, a moving screw 308 is fixedly installed on the moving end of the sub-telescopic cylinder 307, the moving screw 308 is connected to the outer wall of the pressure cylinder 301 by threads to control the movement of the pressure cylinder 301.

[0032] Working principle: When the device is tested, the moving rollers on the outer wall of the shell 201 are used to move the device in the house. When the device is moved in the house, the entire floor of the house must be paved with the closed frame 101, and the test is performed about 7 to 10 days after the paving is completed.

[0033] During the detection process of this device, it is necessary to start the inner motor 203, so that the inner motor 203 drives the inner rotating shaft 204 connected to the output shaft of the inner motor 203 to rotate, and this inner rotating shaft 204 then drives all the inner rotating shafts 204 to rotate through multiple belts 206. When the inner rotating shaft 204 rotates, it will drive all the cams 205 in the outer shell 201 to rotate. At this time, the cams 205 will drive all the swing rods 207 in the outer shell 201 to swing in stages. During the swinging process of the swing rod 207, the swinging of the swing rod 207 will cause the collision ball head 211 at the other end of the swing rod 207 to knock on the tile 100, and the sound of the collision ball head 211 colliding with the tile 100 can be collected by the detection and analysis module 213, and the detection and analysis module 213 will use audio processing technology (such as Fourier transform) to analyze the frequency, amplitude and other characteristics of the sound, and can further determine the emptiness of the bottom of the knocked tile 100.

[0034] When a hole appears at the bottom of the tile 100, the device can perform a hole filling procedure for the tile 100. This type of filling is only suitable for filling a small range of holes, and its filling range can only be a hole that is less than one-third of the tile 100. When filling, first install the side support 104 and the closing frame 101 outside the storage tube 105, and add a filling agent to the storage tube 105. The filling agent can be epoxy resin glue or prepared cement mortar. After preparation, the moving roller will drive the device to move above the corresponding tile 100. , and then align the closing frame 101 with the tiles 100. The purpose of the closing frame 101 is to cover the gaps between the tiles 100. When the closing frame 101 is aligned with the gaps between the tiles 100, the closing frame 101 drives the closing frame 101 to contact the tiles 100 through the telescopic cylinder 103, so that the gaps between the tiles 100 are covered. It is worth noting here that when covering, the material through holes on the closing frame 101 can be aligned with the position of the cavity closest to the tile 100 to facilitate the filling agent to enter the bottom of the tile 100.

[0035] After that, the moving motor 306 can be started, and the moving motor 306 can drive the auxiliary telescopic cylinder 307 and the moving screw 308 to rotate, and the moving screw 308 will drive the pressure cylinder 301 to move towards the tile 100, so that the injection needle 319 on the pressure cylinder 301 can enter the material through hole on the closed frame 101, and the limit ring on the outer wall of the injection needle 319 will limit the depth of the injection needle 319. When the injection needle 319 penetrates into the closed frame 101, the injection needle 319 will be inserted into the gap between the tiles 100, and the injection cylinder 301 can be started at this time. The main pressure motor 108 is started, and the main pressure motor 108 drives the large pressure plate 107 to squeeze the filler in the storage tube 105 through the main pressure screw 109. The filler will enter the pressure tube 301 after passing through the conveying pipe 309 and the feeding pipe 310. At this time, the main motor 305 is started synchronously, and the main motor 305 drives the injection screw 302 to rotate, and the injection screw 302 drives the pressure plate 303 in the feeding pipe 310 to move away from the closing frame 101. In this way, the pressure plate 303 moves synchronously to prevent the filler in the pressure tube 301 from carrying too much air.

[0036] When the pressure cylinder 301 is full of filler, the main motor 305 drives the pressure plate 303 to move toward the closing frame 101, so that the pressure plate 303 can pass the filler in the pressure cylinder 301 through the discharge pipe 314 and then into the bottom of the tile 100. Then, the filler is continuously squeezed by the pressure plate 303 and flows to the hollow at the bottom of the tile 100, thereby filling the hollow at the bottom of the tile 100.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
