Description

Technical Field

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

[0002] The flatness detection of wall surface is a very important link in the construction and decoration process. The main reason is that flatness is an important indicator to measure the quality of wall construction. Through flatness detection, it can effectively reflect the construction quality of the wall to a certain extent. At the same time, the flatness of the wall is directly related to the beauty of indoor and outdoor decoration, as well as the durability and stability of indoor and outdoor decoration projects.

[0003] Currently, wall flatness is typically checked using a straightedge and a feeler gauge. A straightedge is typically a long strip, ranging in length from 1 to 2.5 meters, while a feeler gauge is a measuring tool made up of multiple thin metal sheets. To determine wall flatness, the straightedge is placed against the wall, and the feeler gauge is used to measure the gap between the straightedge and the wall.

[0004] However, the existing straightedge-feeler gauge detection method still has the following problems:

[0005] First, since different building walls have different vertical dimensions, when the vertical dimension of a building wall is small (for example, less than 1 meter), a general ruler cannot be used (this is because a general ruler is around 1 meter to 2.5 meters and cannot be used for walls less than 1 meter), and it is impossible to detect the flatness of such building walls.

[0006] Second, when the vertical dimension of the building wall is large (for example, more than 3 meters), and the length of the ruler is fixed, it is often necessary to move the ruler multiple times in the vertical direction of the building wall to complete the flatness detection of the entire building wall. This not only leads to poor detection accuracy, but also high labor intensity. In addition, there is also the problem of low efficiency of flatness detection.

[0007] Third, when testing the flatness at a higher position on a building wall, it is often necessary to use other tools (e.g., a ladder) to climb up to complete the test. This not only makes the test less safe and more difficult to operate, but also results in a relatively low efficiency in flatness testing.

[0008] Fourth, the straightedge-feeler gauge method has low detection accuracy for walls with local protrusions. This is because it is difficult to accurately and quickly find a reference flat surface corresponding to a wall with local protrusions, which leads to low detection accuracy and low detection efficiency.

DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0038] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are intended to fall within the scope of protection of the present invention.

[0039] In order to facilitate relevant technical personnel to have a clearer and more accurate understanding of the technical solution of the present invention, the existing related technologies and the technical problems existing therein are first described in more detail below.

[0040] Among the current methods for detecting the flatness of building walls, a straightedge-feeler gauge detection method is generally used. Specifically, a long straightedge with a straight edge can be first placed tightly against the wall to be measured, and the straight edge of the straightedge is used to form a comparison with the wall (that is, the wall surface with the largest contact area with the straightedge when the straightedge is stably placed against the wall is used as a reference flat surface. During specific operations, in order to facilitate actual detection, the straight edge of the straightedge that is tightly attached to and parallel to the reference flat surface is used as a reference). The operator judges the flatness of the wall by observing the gap between the straightedge and the wall, and uses a feeler gauge to detect the specific data of the maximum gap, and uses the specific data of the maximum gap as the flatness data.

[0041] However, during actual application, the inventors discovered the following problems:

[0042] First, since the general size of a ruler is between 1 meter and 2.5 meters, when the vertical dimension of a building wall is less than 1 meter, for example, the wall surface under the stairs, the wall surface under the window sill at a lower height, etc., the size of a general ruler is difficult to adapt to the flatness detection needs of such building walls, and it is impossible to realize the flatness detection of such building walls.

[0043] Secondly, when the vertical dimension of the building wall surface is large, for example, the wall surface of a high commercial property, the wall surface of a high residential building, etc., it is often necessary to move the ruler multiple times in the vertical direction of the building wall surface to complete the flatness detection of the corresponding wall surface. In the process of moving the ruler, the reference flat surface will inevitably change slightly, so that the wall surface in the same vertical direction is detected corresponding to different reference flat surfaces, which will inevitably have some errors, resulting in poor detection accuracy. In addition, due to the multiple movements of the ruler, it involves climbing, moving the ruler, and using the plug gauge to detect the flatness data, which has a high labor intensity. Furthermore, the flatness detection in a vertical direction requires more movements of the ruler, resulting in a long detection time and low detection efficiency.

[0044] Thirdly, when detecting the flatness of a high position of the building wall, other tools such as a ladder are often needed to climb to complete the detection, which not only has poor safety and high operation difficulty, but also has low flatness detection efficiency.

[0045] Fourthly, the ruler-plug gauge method has low detection accuracy for wall surfaces with local protrusions. This is because it is difficult to accurately and quickly find the reference flat surface corresponding to the wall surface with local protrusions. For example, when a wall is 2 meters high and has a local protrusion at a position 1.2 meters from the ground, the 2-meter ruler will be in close contact with the wall when the force applied to the ruler is closer to the top of the ruler, and the top of the ruler will be in close contact with the wall, while the bottom of the ruler will be separated from the wall. At this time, the reference flat surface found is the extension of the ruler in this state, i.e., a downward inclined surface with the top of the wall as the starting point and a certain position away from the wall surface as the end point. When the force applied to the ruler is closer to the bottom of the ruler, the bottom of the ruler will be in close contact with the wall, while the top of the ruler will be separated from the wall. At this time, the reference flat surface found is the extension of the ruler in this state, i.e., an upward inclined surface with the bottom of the wall as the starting point and a certain position away from the wall surface as the end point. Thus, different force positions will result in completely different reference flat surfaces, leading to low detection accuracy.

[0046] To at least partially solve the above technical problems, the present application provides a brand-new solution, i.e., a building wall flatness detection device of the present application. The building wall flatness detection device of the present application can effectively adapt to wall surfaces with any vertical dimension, effectively improve the accuracy of flatness detection, reduce labor intensity and operation difficulty, improve the efficiency of flatness detection, and improve the safety during the detection process.

[0047] The technical solution of the present invention is described in detail below with reference to the accompanying drawings.

[0048] Example 1

[0049] like Figures 1 to 4 As shown, this embodiment provides a building wall flatness detection device 100, including a base 1, a detection component 2 and a control unit (not shown). The base 1 is used to be placed on the ground. The detection component 2 includes a driving member 21, a mounting block 22 and a detection member 23. The driving member 21 is installed on the base 1. The output end of the driving member 21 is connected to the mounting block 22 to drive the mounting block 22 to move in the vertical direction. One side of the mounting block 22 is recessed inward to form a receiving cavity 221; the detection member 23 includes an elastic body 231, a touch block 232, a roller 233 and a plurality of contact switches 234. One end of the elastic body 231 is installed in the receiving cavity 221. The other end of the elastic body 231 is connected to a trigger block 232, which is axially movable within the accommodating cavity 221. A roller 233 is located outside the accommodating cavity 221 and is rotatably mounted on the end of the trigger block 232 away from the elastic body 231. The roller 233 is configured to roll on the wall. Several contact switches 234 are spaced apart along the axial direction of the accommodating cavity 221 within the accommodating cavity 221. The contact switches 234 are configured to be triggered by the trigger block 232. A control unit is mounted on the base 1 and is electrically connected to the drive member 21 and the several contact switches 234.

[0050] In order to facilitate relevant technical personnel to have a clearer and more accurate understanding of the technical solution of the present invention, the working process / working principle of the above-mentioned implementation method is first described below.

[0051] When it is necessary to perform a flatness test on a certain wall, the building wall flatness testing device 100 of the present invention can be placed at the root of the wall to be tested, and then the roller 233 can be made to be in close contact with the wall. Then the driving member 21 can be started. The driving member 21 pushes the mounting block 22 to gradually rise in the vertical direction. When the mounting block 22 rises, it will drive the testing member 23 to gradually rise in the vertical direction. During the rising process of the testing member 23, it is ensured that the roller 233 is always in close contact with the wall.

[0052] As the roller 233 rises, if there is a depression in the wall, the roller 233 and the trigger block 232 will move away from the mounting block 22, that is, toward the wall, under the action of the elastic body 231. At this time, the trigger block 232 will lose contact with some of the contact switches 234 in the accommodating cavity 221 that are away from the wall (correspondingly, the trigger signals of these contact switches 234 will be eliminated). Alternatively, the trigger block 232 will come into contact with some of the contact switches 234 in the accommodating cavity 221 that are close to the wall (correspondingly, the trigger signals of these contact switches 234 will be activated). In this way, by identifying the trigger signal status of the contact switches 234 (correspondingly, the trigger signals of some contact switches 234 located in the middle of the accommodating cavity 221 are always in the triggered state), the forward movement distance of the roller 233 (i.e., the movement distance toward the wall) can be accurately and reliably calculated, thereby obtaining the flatness data of the wall.

[0053] Accordingly, if there is a protrusion on the wall, the roller 233 and the trigger block 232 will move toward the mounting block 22 under the action of the elastic body 231, that is, move away from the wall. At this time, the trigger block 232 will come into contact with some of the contact switches 234 in the accommodating cavity 221 that are close to the wall (correspondingly, the trigger signals of these contact switches 234 will be activated). Alternatively, the trigger block 232 will lose contact with some of the contact switches 234 in the accommodating cavity 221 that are close to the wall (correspondingly, the trigger signals of these contact switches 234 will disappear). In this way, by identifying the trigger signal status of the contact switches 234 (correspondingly, the trigger signals of some contact switches 234 located in the middle of the accommodating cavity 221 are always in the triggered state), the retreat distance of the roller 233 (i.e., the movement distance away from the wall) can be accurately and reliably calculated, thereby obtaining the flatness data of the wall.

[0054] Through the above technical solution, first, the building wall flatness detection device 100 of the present invention can be adapted to the vast majority of building walls, and can reliably meet the flatness detection requirements of walls with smaller vertical dimensions. Compared with the detection method of straightedge-feeler gauge in the existing related technology, it has better versatility.

[0055] Second, when the building wall flatness detection device 100 of the present invention performs flatness detection, as long as the driving height of the driving member 21 is sufficient, compared with the detection method of the straightedge-feeler gauge in the existing related technology, there is no need to move the straightedge multiple times, and there is no problem of changes in the reference flatness surface. At the same time, there is no process such as equal height operation. In other words, it can effectively reduce the labor intensity during the flatness detection process, improve the accuracy of the flatness detection, reduce the detection time, and improve the detection efficiency.

[0056] Third, when detecting the flatness at a higher position of the wall, the building wall flatness detection equipment 100 of the present invention does not need to rely on contour tools to complete the monitoring, which can effectively ensure the safety of the detection process and reduce the difficulty of operation. At the same time, it can also improve the detection efficiency to a certain extent.

[0057] Fourth, when applied to a wall with local protrusions, the building wall flatness detection device 100 of the present invention can quickly and relatively accurately determine the reference flat surface corresponding to the wall, and there will be no problem of the reference flat surface changing due to different force application positions, which can effectively improve the accuracy of the detection.

[0058] In the above technical solution, it is understood that the distance between each two adjacent contact switches 234 can be adjusted according to the size of the contact switches 234 and the specific conditions of the wall surface. For example, the distance between each two adjacent contact switches 234 can be set to 1 mm-5 mm. In this way, the accuracy of the building wall flatness detection device 100 of the present invention is correspondingly 1 mm-5 mm. The present invention is not specifically limited to this.

[0059] For building walls, in addition to flatness detection, there is also verticality detection. At present, verticality detection is generally carried out by the hanging line method (i.e., using a plumb line for measurement), the laser instrument detection method (i.e., using a laser instrument to detect the verticality of the wall), the vertical ruler detection method (i.e., using a vertical ruler for detection) or the total station detection method (i.e., using a total station for detection).

[0060] However, the above detection methods are independent of the flatness detection, that is, other components or equipment are required to detect the verticality of the wall. This will make the entire wall detection process (including flatness and verticality) time-consuming, the detection efficiency is relatively low, and the operation difficulty (for example, the hanging line method requires a stable and reliable hanging plumb line, and for another example, the laser instrument detection method requires the precise setting of the laser instrument's measurement position) is also high.

[0061] In view of this, in one embodiment of the present invention, Figure 1 and Figure 2 As shown, the base 1 of the present invention may include a first plate body 11, a second plate body 12, a leveling connector 13 and a leveling bubble 14. The first plate body 11 is used to be placed on the ground, and the second plate body 12 is spaced apart above the first plate body 11. The second plate body 12 is used to install a driving member 21 and a control unit. The leveling connector 13 is arranged between the first plate body 11 and the second plate body 12 for adjusting the second plate body 12 to a horizontal level. The leveling bubble 14 is arranged on the second plate body 12.

[0062] In this embodiment, first, the first plate body 11, the second plate body 12, the leveling connecting piece 13 and the leveling bubble 14 are arranged in this way, so that the base 1 can be adjusted to a horizontal position, and then in combination with the detection piece 23 in the above embodiment, the driving direction of the driving piece 21 is strictly along the vertical direction, so that the verticality data of the wall surface can be measured while measuring the flatness.

[0063] Specifically, for example, when the wall surface is inclined towards the direction away from the building wall flatness detection device 100, the flatness data measured by the building wall flatness detection device 100 will show a certain trend (i.e. gradually increasing trend), which can assist in judging that the wall surface is inclined to a certain extent, and for another example, when the wall surface is inclined towards the direction close to the building wall flatness detection device 100, the flatness data measured by the building wall flatness detection device 100 will show a certain trend (i.e. gradually decreasing trend), which can assist in judging that the wall surface is inclined to a certain extent.

[0064] Secondly, the base 1 arranged in this way can also be adapted to uneven ground (because when detecting the flatness or verticality of the wall surface, the ground may not be flat, and there may be certain unevenness), so that the building wall flatness detection device 100 of the present application has better environmental applicability.

[0065] In an embodiment of the present application, as shown in Figure 1 and Figure 2 The building wall flatness detection device 100 of the present application can further comprise a housing 3 and a display piece 4, the housing 3 is installed on the base 1, the control unit is arranged in the housing 3, the display piece 4 is installed on the housing 3, and the display piece 4 is electrically connected with the control unit for displaying the flatness data of the detected wall surface.

[0066] In this way, the housing 3 can protect the control unit, and the display piece 4 can display the flatness data of the wall surface in real time and intuitively, which is more convenient for the operator to judge the flatness of the wall surface in real time, and is also convenient for the operator to infer the verticality of the wall surface in combination with the change of the flatness data.

[0067] In an embodiment of the present application, the driving piece 21 of the present application can be arranged as an electric push rod, and the output end of the electric push rod is connected with the mounting block 22.

[0068] The electric push rod has the characteristics of precise control (the pushing speed, position and force of the electric push rod can be precisely adjusted by a control unit to realize precise linear motion control), simple operation (operation can be realized by a button or a remote controller, compared with a manually adjusted pushing mode, the operation is more simple, and manual operation strength can be effectively reduced), flexible installation (the electric push rod has a compact structure, is convenient to install, can be installed horizontally, vertically or obliquely, and is suitable for different installation environments), and strong environmental adaptability (the electric push rod can work in various environments, such as high temperature, low temperature, humidity or dusty environment), and can be well adapted to the flatness and perpendicularity detection of a wall surface.

[0069] In an embodiment of the present application, as shown in Figure 3 and Figure 4 The accommodating cavity 221 can include a first cavity 2211 and a second cavity 2212 that are in communication with each other, one end of the first cavity 2211 extends to the side of the mounting block 22 to make the end open, and the radial dimension of the second cavity 2212 is greater than that of the first cavity 2211; the elastic body 231 includes a mounting portion 2311 and a connecting portion 2312 that are connected to each other, the radial dimension of the mounting portion 2311 is greater than that of the connecting portion 2312, the mounting portion 2311 is mounted in the second cavity 2212, the connecting portion 2312 is located in the first cavity 2211 and connected with the trigger block 232, and the trigger block 232 is movably arranged in the first cavity 2211.

[0070] In this way, the mounting portion 2311 arranged in this way can be stably and reliably mounted in the second cavity 2212 with a larger radial dimension, so as to effectively ensure that the elastic body 231 can stably and reliably continue to play its role to measure the flatness data of the wall surface in different situations.

[0071] Meanwhile, the elastic body 231 arranged in this way does not need to be fixedly connected to the inner wall of the accommodating cavity 221, but can be clamped in the accommodating cavity 221 only by relying on the structural characteristics of the elastic body 231, so that the assembly difficulty is lower and the assembly is more convenient.

[0072] In an embodiment of the present application, as shown in Figure 4 The mounting portion 2311 and the connecting portion 2312 of the elastic body 231 can be formed into coaxially connected cylindrical structures, respectively.

[0073] In this way, the elastomer 231 configured in this way has the following advantages: uniform stress distribution (the cylindrical shape can provide a relatively uniform stress distribution when subjected to axial or radial loads, reduce stress concentration, and improve the fatigue life of the structure), structural stability (the cylindrical shape has higher structural stability, can maintain its shape when subjected to compression or tension, is not easy to deform, and can be well adapted to the accommodating cavity 221), good mechanical properties (when the cylindrical elastomer 231 is under load, its radial and axial mechanical properties are relatively balanced, and it is suitable for a variety of mechanical environments), and material saving (compared with other shapes, the cylindrical elastomer 231 saves more material).

[0074] In one embodiment of the present invention, Figure 3 and Figure 4 As shown, the trigger block 232 of the present invention can be formed into a prismatic structure, and the shape of the accommodating cavity 221 is adapted to the trigger block 232 to prevent the trigger block 232 from rotating.

[0075] In this way, by setting the trigger block 232 and the accommodating cavity 221 in this way, it is possible to effectively prevent the trigger block 232 from rotating circumferentially while ensuring the axial movement ability of the trigger block 232, and ensure the constancy of the moving direction of the roller 233, thereby effectively improving the accuracy of detection.

[0076] Since each contact switch 234 has a corresponding data transmission line, when a plurality of contact switches 234 are arranged at intervals along the axial direction of the accommodating cavity 221 , problems such as entanglement and interference of the multiple data transmission lines may occur.

[0077] In view of this, in one embodiment of the present invention, several contact switches 234 of the present invention are arranged in the accommodating cavity 221 at intervals along the axial direction of the accommodating cavity 221, and several contact switches 234 are arranged in the circumferential direction of the accommodating cavity 221 at intervals.

[0078] In this way, the data transmission lines corresponding to the contact switches 234 can be spaced apart in the mounting block 22 along the axial and circumferential directions of the accommodating cavity 221 , thereby effectively avoiding entanglement or interference of the connection lines of the contact switches 234 .

[0079] In one embodiment of the present invention, Figure 3 As shown, the plurality of contact switches 234 of the present invention may be arranged in a spiral form within the accommodating cavity 221 .

[0080] In this way, first, the several contact switches 234 distributed in a spiral shape can enable the data transmission lines corresponding to the several contact switches 234 to be arranged at intervals from each other along the circumference of the accommodating cavity 221, and to be synchronously connected to the control unit along the axial direction of the accommodating cavity 221, which can effectively ensure the relative independence of the data transmission lines, avoid their entanglement or interference with each other, and also facilitate the wiring of the data transmission lines in the installation block 22.

[0081] Second, the spirally distributed contact switches 234 have a sufficiently large spacing between each other (whether in the circumferential or axial direction of the accommodating cavity 221) so that the movement distance of the touch block 232 can be accurately reflected by the corresponding unique contact switch 234. This not only effectively reduces the number of touch switches arranged, saves arrangement costs and reduces arrangement difficulty, but also avoids false alarms or synchronous triggering (or releasing) of the touch switches, thereby effectively ensuring the triggering effectiveness of the trigger switch and further ensuring the accuracy of the detection results.

[0082] The above are only specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions within the technical scope disclosed by the present invention should be covered by the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
