Description

Technical Field

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

[0002] Building walls mainly play roles such as bearing loads, dividing spaces, heat insulation, etc. During the inspection process, measuring whether the wall is inclined is a very important step. The verticality of the wall is related to the load-bearing capacity and stability of the wall. Most of the existing verticality measuring devices measure by the method that workers use a plumb bob to be naturally vertical under the action of gravity, and some also use mutually perpendicular rods to measure the verticality of the wall surface. These are measured by workers directly holding and operating, and the measurement accuracy is relatively low, which may cause large errors, affecting the measurement results, and there may also be potential safety hazards. At the same time, if there are some impurities or uneven places on the wall, it will also affect the measurement results. At the same time, the existing measuring devices cannot lock the uneven positions of the wall.

[0003] Moreover, after some walls are used for a period of time, cracks will appear. Wall cracks are a common damage method in buildings. As an initial damage, timely repair or restoration can reduce safety hazards; when cracks appear in the wall and need to be detected, it is mostly that the surveyors move along the wall to search for different crack positions for subsequent repair. However, this method requires the surveyors to always stay at a relatively high position, and the physical safety of the surveyors cannot be guaranteed. Moreover, the edges of the wall cracks often contain accumulated dust and debris, resulting in inaccurate measurement during the measurement process, affecting the detection effect of the cracks. Summary of the Invention

[0015] After adopting the above structure, the beneficial effects of the present invention are as follows:

[0016] (1) The insertion rod moves up and down along the limiting rod, driving the mounting seat to move. The mounting seat drives the second pressing plate to move towards the first pressing plate. The second pressing plate presses the extrusion bladder between the first pressing plate and the second pressing plate. The gas in the extrusion bladder enters the ventilation cavity connected thereto through the connecting pipe, and is conveyed to different detection plates through the elastic pipe. The gas in the detection plate is sprayed onto the wall surface through the air outlet holes to clean the impurities on the wall surface, and then the crack detection device is used to detect the cracks in the wall.

[0017] (2) After detecting the cracks in the wall, the distance between the first measuring members has been adjusted to facilitate the detection of positions at different heights of the wall. Move the device so that the extrusion member fits against the wall. The wall exerts a reaction force on the extrusion member, the extrusion member drives the measuring rod, the measuring rod squeezes the spring, the spring squeezes the pressure sensor, and multiple pressure values on the first measuring assembly are transmitted into the controller. The controller can determine whether the wall at that position is vertical and whether there are uneven positions on the wall based on the values. Description of the Drawings

[0035] A fourth limiting groove 12, a third limiting groove 13, a second limiting groove 14 and a first limiting groove 15 are sequentially installed on the side wall of the first rotating roller 8 from top to bottom. The first limiting groove 15 is arranged in an arc structure. The second limiting groove 14, the third limiting groove 13 and the fourth limiting groove 12 are all spiral structures, and the spiral pitches of the second limiting groove 14, the third limiting groove 13 and the fourth limiting groove 12 increase in sequence. The second limiting groove 14, the third limiting groove 13 and the fourth limiting groove 12 are symmetrically provided with two groups with the horizontal center line of the first limiting groove 15 as the axis of symmetry. The first measuring member 11 is respectively movably clamped in the first limiting groove 15, the second limiting groove 14, the third limiting groove 13 and the fourth limiting groove 12.

[0036] Any one of the said measuring members 11 includes a mounting base 16, the mounting base 16 is movably arranged on the first limiting rod 10, the first limiting rod 10 restricts the movement of the mounting base 16, the mounting bases 16 at the uppermost end and the lowermost end are both connected to the second pressing plate 39, the side wall of the mounting base 16 is provided with inserting rods 17, the inserting rods 17 are respectively movably clamped in the first limiting groove 15, the second limiting groove 14, the third limiting groove 13 and the fourth limiting groove 12, the ends of the inserting rods 17 arranged in the first limiting groove 15, the second limiting groove 14, the third limiting groove 13 and the fourth limiting groove 12 are movably installed with balls, which can reduce the friction between the inserting rods 17 and the first limiting groove 15, the second limiting groove 14, the third limiting groove 13 and the fourth limiting groove 12, the other side wall of the mounting base 16 is also provided with a slot hole 18, a pressure sensor 19 and a spring 20 are arranged in the slot hole 18, the pressure sensor 19 is arranged on the inner side wall of the slot hole 18, one end of the spring 20 is arranged on the pressure sensor 19, the other end of the spring 20 is installed with a measuring rod 21, one end of the measuring rod 21 extends out of the mounting base 16, and an extrusion member 22 is installed at one end of the measuring rod 21 extending out of the mounting base 16;

[0040] A plurality of first threaded holes 26 for fixing are evenly arranged at equal intervals in a ring shape on the upper wall of the first lower fixing plate 7 in the first measuring component 3. Threaded holes for fixing are also provided on the upper wall of the support plate 1. The first threaded holes 26 and the threaded holes communicate with each other. A plurality of threaded rods 27 for installation are evenly arranged at equal intervals in a ring shape on the bottom wall of the second lower fixing plate 47 in the first connecting component 5. A sleeve 28 is movably installed at the center position of the bottom wall of the second lower fixing plate 47. The sleeve 28 is connected to the lower end of the second rotating roller 48.

[0041] It should be noted that when the measuring component needs to be fixed on the support plate 1, the first lower fixing plate 7 at the lower end of the measuring component is placed on the upper wall of the support plate 1, the first threaded holes 26 and the threaded holes are connected in a penetrating manner, and then fixed with bolts;

[0042] When the connection components need to be installed, install the lower fixing plate II 47 at the lower end of the connection component I 5 on the upper fixing plate I 9 at the upper end of the measurement component I 3. Insert the connecting rod 23 at the upper end of the measurement component I 3 into the sleeve 28 at the lower end of the connection component I 5. At this time, the threaded rod 27 is arranged through the connection hole 25, and the position of the threaded hole II 24 is placed opposite to the position of the threaded hole III 29. Pass the threaded rod 27 through the threaded hole II 24 and the threaded hole III 29 and then fix it with bolts. Then rotate the nut onto the threaded rod 27 protruding from the bottom wall of the upper fixing plate I 9 to achieve fixation. At the same time, the connection component II 6 is installed according to the above steps.

[0043] The driving component 2 includes a mounting plate 30, and the mounting plate 30 is arranged on the bottom wall of the support plate 1. The driving component 2 further includes a driving roller 31 and a driven roller 32.

[0044] It should be noted that when the motor 33 works, it drives the driving roller 31 to rotate. The driving roller 31 drives the driven roller 32 to rotate through the belt 34. When the driving roller 31 and the driven roller 32 rotate, they respectively drive the first rotating roller 8 in the measurement component I 3 and the measurement component II 4 to rotate, adjusting the distance between the first measuring parts 11.

[0045] The specific use is as follows:

[0046] First, fix the measurement component I 3 on the support plate 1 with bolts. After the measurement component II 4 is arranged at the end of the sliding groove away from the measurement component I 3, it is also fixed on the support plate 1 with bolts;

[0047] If the height of the wall to be measured is relatively low and the detection can be achieved only through the measurement component I 3 and the measurement component II 4, then there is no need to install the connection component I 5 and the connection component II 6. At this time, when the motor 33 works, it drives the driving roller 31 to rotate. The driving roller 31 drives the driven roller 32 to rotate through the belt 34. When the driving roller 31 and the driven roller 32 rotate, they respectively drive the first rotating roller 8 in the measurement component I 3 and the measurement component II 4 to rotate;

[0048] If the height of the wall to be measured is relatively high and the detection cannot be achieved only through the measurement component I 3 and the measurement component II 4, then the connection component I 5 and the connection component II 6 need to be installed. The specific operation is as follows:

[0049] When installing the connection component, install the lower fixing plate two 47 at the lower end of the connection component one 5 on the upper fixing plate one 9 at the upper end of the measuring component one 3. Insert the connecting rod 23 at the upper end of the measuring component one 3 into the sleeve 28 at the lower end of the connection component one 5. At this time, the threaded rod 27 is arranged through the connection hole 25, and the position of the threaded hole two 24 is placed opposite to the position of the threaded hole three 29. Pass the threaded rod 27 through the threaded hole two 24 and the threaded hole three 29 and then fix it with bolts, realizing the connection between the sleeve 28 and the connecting rod 23. Then rotate the nut onto the threaded rod 27 extending from the bottom wall of the upper fixing plate one 9 to achieve fixation again. At the same time, the connection component two 6 is installed according to the above steps. At this time, the motor 33 works to drive the driving roller 31 to rotate. The driving roller 31 drives the driven roller 32 to rotate through the belt 34. When the driving roller 31 and the driven roller 32 rotate, they respectively drive the rotating roller one 8 in the measuring component one 3 and the measuring component two 4 to rotate. At the same time, the measuring component one 3 drives the rotation of the rotating roller two 48 on the connection component one 5 through the connecting rod 23 and the sleeve 28, and the measuring component two 4 drives the rotation of the rotating roller two 48 on the connection component two 6 through the connecting rod 23 and the sleeve 28.

[0050] When cleaning the wall and detecting wall cracks at the same time:

[0051] When detecting the verticality of the wall, first move the device to a position where the extrusion part 22 is close to the wall but not in contact with the wall. Then adjust the distance between the measuring parts one 11 according to the height of the wall. The motor 33 works to drive the rotating roller one 8 to rotate. The rotating roller one 8 drives the limiting groove one 15, the limiting groove two 14, the limiting groove three 13 and the limiting groove four 12 on it to rotate. The limiting groove one 15, the limiting groove two 14, the limiting groove three 13 and the limiting groove four 12 drive the internal insertion rod 17. The insertion rod 17 moves along the tracks of the limiting groove one 15, the limiting groove two 14, the limiting groove three 13 and the limiting groove four 12. At the same time, under the action of the limiting rod one 10, the insertion rod 17 can only move up and down along the limiting rod one 10. The insertion rod 17 drives the mounting seat 16 to move. The mounting seat 16 drives the pressing plate two 39 to move towards the pressing plate one 38. The pressing plate two 39 squeezes the extrusion bladder 40 between the pressing plates one 38. The gas in the extrusion bladder 40 enters the air cavity 41 connected to it through the connecting pipe 42, and the gas is transported to different detection plates 36 through the elastic pipe 45. The gas in the detection plate 36 is sprayed onto the wall surface through the air holes 44 to clean the impurities on the wall surface, and then the wall cracks are detected through the crack detection device 43.

[0052] Detect the verticality of the wall:

[0053] 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:

[0054] If the difference between the values ​​is small, it is considered that the wall is vertically set and there is no uneven position;

[0055] 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.

[0056] If most of the values ​​decrease or increase from top to bottom, the wall at that location is tilted.

[0057] Although the embodiments of the present invention have been shown and described, it is understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents. In short, if those skilled in the art are inspired by them and design structural modes and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they shall all fall within the scope of protection of the present invention.
