Description

Technical Field

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

[0002] The flatness detection of the 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] At present, when checking the flatness of a wall, a ruler and a feeler gauge are generally used. The ruler is generally in the shape of a long strip, and its length is generally between 1 meter and 2.5 meters, and the feeler gauge is a measuring tool composed of multiple thin metal sheets. During use, the straight edge of the ruler is generally pressed against the wall, and then the feeler gauge is used to measure the specific size of the gap between the ruler and the wall, so as to judge the flatness of the wall.

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

[0005] Second, when the vertical dimension of the building wall is large (for example, more than 3 meters), and the length dimension 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. In this way, there is not only the problem of poor detection accuracy, but also the problem of high labor intensity. In addition, there is also the problem of low efficiency of flatness detection.

[0006] Third, when testing the flatness at a higher position on a building wall, it is often necessary to use other tools (such as 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.

[0007] Fourth, the detection accuracy of the straightedge-feeler gauge method for walls with local protrusions is not high. This is because it is difficult to accurately and quickly find a reference flat surface corresponding to the wall with local protrusions, which leads to the problems of low detection accuracy and low detection efficiency.

DETAILED DESCRIPTION

[0026] 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.

[0027] 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 claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] 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.

[0029] In the current building wall flatness detection method, it is generally carried out by a straightedge-feeler gauge detection method. Specifically, a long straightedge with a straight edge can be used to cling to the wall to be tested, and the straight edge of the straightedge can be used to compare with the wall (that is, the wall that has most of the contact area with the straightedge when the straightedge can be stably attached to the wall is used as a reference flat surface. In specific operations, in order to facilitate actual detection, the straight edge of the straightedge that is close 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.

[0030] However, in the actual application process, the inventor found the following problems: 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 windowsill 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.

[0031] Second, when the vertical dimension of the building wall is large, for example, the wall surface of a commercial property with a high ceiling, the wall surface of a residential building with a high ceiling, etc., 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 corresponding wall surface. In the process of moving the ruler, slight changes in the reference flatness surface will inevitably be involved, so that the wall surface in the same vertical direction corresponds to different reference flatness surfaces for detection, and there will inevitably be certain errors, and there is a problem of poor detection accuracy. At the same time, due to the multiple movements of the ruler, it also involves the processes of climbing, moving the ruler, and using a feeler gauge to detect specific flatness data, and there is a problem of high labor intensity. In addition, the ruler needs to be moved multiple times to complete the flatness detection in a certain vertical direction, which will inevitably require the ruler to be moved more times for the flatness detection of the entire wall, and there are problems of long detection time and low detection efficiency.

[0032] Third, when testing the flatness at a higher position on a building wall, it is often necessary to use other tools (such as 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.

[0033] Fourth, the detection accuracy of the ruler-feeler gauge method for walls with local protrusions is not high. This is because it is difficult to accurately and quickly find a reference flat surface corresponding to the wall with local protrusions. For example, when a wall is 2 meters high and there is a local protrusion 1.2 meters above the ground, when a 2-meter ruler is close to the wall, when the force applied to the ruler is closer to the top of the ruler, the top of the ruler will be close to the wall, and the bottom of the ruler will be separated from the wall. At this time, the reference flat surface found is The reference flat surface is an extension of the ruler in this state, that is, a surface that starts from the top of the wall and ends at a position a distance away from the wall surface, and is tilted downward. When the force applied to the ruler is closer to the bottom of the ruler, the bottom of the ruler will be close to the wall, and the top of the ruler will be separated from the wall. At this time, the reference flat surface is an extension of the ruler in this state, that is, a surface that starts from the bottom of the wall and ends at a position a distance away from the wall surface, and is tilted upward. In this way, different force application positions will result in completely different reference flat surfaces, which will also lead to the problem of low detection accuracy.

[0034] In order to at least partially solve the above technical problems, the present invention provides a new solution, namely, the building wall flatness detection device of the present invention. Through the building wall flatness detection device of the present invention, not only can it be effectively adapted to walls with any vertical dimensions, but it can also effectively improve the accuracy of flatness detection, reduce labor intensity and operating difficulty, and improve the efficiency of flatness detection and the safety during the detection process.

[0035] The technical solution of the present invention is described in detail below with reference to the accompanying drawings.

[0036] Example 1 like Figures 1 to 4As 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 trigger 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 the trigger block 232, and the trigger block 232 is axially movable in the accommodating cavity 221. The roller 233 is located outside the accommodating cavity 221 and is rotatably installed at one end of the trigger block 232 away from the elastic body 231. The roller 233 is used to roll on the wall. A plurality of contact switches 234 are arranged in the accommodating cavity 221 at intervals along the axial direction of the accommodating cavity 221. The contact switches 234 are configured to be triggered by the trigger block 232. The control unit is installed on the base 1, and the control unit is electrically connected to the driving member 21 and the plurality of contact switches 234 respectively.

[0037] 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.

[0038] When it is necessary to perform a flatness test on a certain wall, the building wall flatness test 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 close to the wall. Then the driving member 21 can be started. The driving member 21 pushes the installation block 22 to gradually rise in the vertical direction. When the installation block 22 rises, it will drive the detection member 23 to gradually rise in the vertical direction. During the rising process of the detection member 23, it is ensured that the roller 233 is always in close contact with the wall.

[0039] As the roller 233 rises, if there is a depression on the wall, the roller 233 and the trigger block 232 will move in a direction away from the mounting block 22 under the action of the elastic body 231, that is, move toward the wall. At this time, the trigger block 232 will be out of contact with some of the contact switches 234 in the accommodating cavity 221 that are far from the wall (correspondingly, the trigger signals of these contact switches 234 will disappear), or the trigger block 232 will be in 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 switch 234 (correspondingly, the trigger signals of some of the 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 (that is, the movement distance toward the wall) can be accurately and reliably calculated, thereby obtaining the flatness data of the wall. Correspondingly, if there is a protrusion on the wall, the roller 233 and the trigger block 232 will move towards the direction close to 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 close to the wall among the several contact switches 234 in the accommodating cavity 221 (correspondingly, the trigger signals of these contact switches 234 will be started), or the trigger block 232 will be out of contact with some of the contact switches 234 close to the wall among the several contact switches 234 in the accommodating cavity 221 (correspondingly, the trigger signals of these contact switches 234 will disappear). In this way, by identifying the trigger signal status of the contact switch 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 (that is, the movement distance away from the wall) can be accurately and reliably calculated, so that the flatness data of the wall can be obtained.

[0040] Through the above technical scheme, firstly, the building wall flatness detection device 100 of the present invention can be adapted to most 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.

[0041] 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.

[0042] Third, when detecting the flatness at a higher position of the wall, the building wall flatness detection device 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.

[0043] 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.

[0044] In the above technical solution, it can be understood that the distance between each two adjacent contact switches 234 can be adjusted according to the size of the contact switch 234 and the specific conditions of the wall. For example, the distance between each two adjacent contact switches 234 can be set to 1mm-5mm. In this way, the accuracy of the building wall flatness detection device 100 of the present invention is correspondingly 1mm-5mm. The present invention does not make specific limitations on this.

[0045] 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).

[0046] However, the above detection methods are independent of the flatness detection, that is, other components or equipment are needed 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 wire method requires stable and reliable hanging of the 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.

[0047] 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, the second plate body 12 is spaced 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 be horizontal, and the leveling bubble 14 is arranged on the second plate body 12.

[0048] Thus, in this embodiment, firstly, the base 1 can be adjusted to a horizontal position by utilizing the first plate body 11, the second plate body 12, the leveling connector 13 and the leveling bubble 14 thus arranged, and then combined with the detection member 23 in the above embodiment, the driving direction of the driving member 21 can be strictly moved in the vertical direction, so that the verticality data of the wall can be measured while measuring the flatness.

[0049] Specifically, for example, when the wall is tilted in a direction away from the building wall flatness detection device 100 of the present invention, the flatness data measured by the building wall flatness detection device 100 of the present invention will show a certain change trend (i.e., a gradually increasing trend), which can assist in judging that the wall has a certain tilt. For another example, when the wall is tilted in a direction close to the building wall flatness detection device 100 of the present invention, the flatness data measured by the building wall flatness detection device 100 of the present invention will show a certain change trend (i.e., a gradually decreasing trend), which can assist in judging that the wall has a certain tilt.

[0050] Second, by configuring the base 1 in this way, it can also be adapted to uneven ground (this is because when detecting the flatness or verticality of the wall, the ground is not necessarily leveled and may have certain unevenness). In this way, the building wall flatness detection device 100 of the present invention can have better environmental applicability.

[0051] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, the building wall flatness detection device 100 of the present invention can also include a shell 3 and a display element 4, the shell 3 is installed on the base 1, the control unit is arranged in the shell 3, the display element 4 is installed on the shell 3, and the display element 4 is electrically connected to the control unit for displaying the flatness data of the detected wall.

[0052] In this way, the shell 3 provided can protect the control unit. At the same time, the display element 4 can instantly and intuitively display the flatness data of the wall, making it easier for the operator to judge the flatness of the wall in real time, and to infer the verticality of the wall based on the changes in the flatness data.

[0053] In one embodiment of the present invention, the driving member 21 of the present invention may be configured as an electric push rod, and the output end of the electric push rod is connected to the mounting block 22 .

[0054] Electric linear actuators have the characteristics of precise control (the control unit can accurately adjust the propulsion speed, position and force of the electric linear actuator to achieve precise linear motion control), easy operation (operation can be achieved through buttons or remote controls, which is easier to operate than the manual adjustment method and can effectively reduce the intensity of manual operation), flexible installation (electric linear actuators have a compact structure and are easy to install. They can be installed horizontally, vertically or at an angle to adapt to different installation environments) and strong environmental adaptability (electric linear actuators can work in a variety of environments, such as high temperature, low temperature, humid or dusty environments), and can be well adapted to the flatness and verticality detection of walls.

[0055] In one embodiment of the present invention, Figure 3 and Figure 4 As shown, the accommodating cavity 221 of the present invention may include a first cavity 2211 and a second cavity 2212 which are interconnected, 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 larger than the radial dimension of the first cavity 2211; the elastomer 231 includes a mounting portion 2311 and a connecting portion 2312 which are interconnected, the radial dimension of the mounting portion 2311 is larger than the radial dimension of the connecting portion 2312, the mounting portion 2311 is installed in the second cavity 2212, the connecting portion 2312 is located in the first cavity 2211 and is connected to the trigger block 232, and the trigger block 232 is movably arranged in the first cavity 2211.

[0056] In this way, the mounting portion 2311 thus configured can be stably and reliably installed in the second cavity 2212 having a larger radial dimension, thereby effectively ensuring that the elastomer 231 can continue to play its role stably and reliably, so as to be able to measure the flatness data of the wall in different situations.

[0057] At the same time, the elastic body 231 configured in this way does not need to be fixedly connected to the inner wall of the accommodating cavity 221, and can be snapped into the accommodating cavity 221 only by relying on the structural characteristics of the elastic body 231, which has low assembly difficulty and is more convenient.

[0058] In one embodiment of the present invention, Figure 4 As shown, the mounting portion 2311 and the connecting portion 2312 of the elastic body 231 of the present invention can be respectively formed as coaxially connected cylindrical structures.

[0059] In this way, the elastomer 231 configured as such 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 high structural stability, can maintain its shape when subjected to compression or tension, is not easily deformed, and can be well adapted to the receiving cavity 221), good mechanical properties (when the cylindrical elastomer 231 bears a load, its mechanical properties in the radial and axial directions are relatively balanced and suitable for various mechanical environments), and material saving (compared with other shapes, the cylindrical elastomer 231 saves more materials).

[0060] In one embodiment of the present invention, as Figure 3 and Figure 4 shown, the trigger block 232 of the present invention can be formed into a prismatic structure, and the shape of the receiving cavity 221 is adapted to the trigger block 232 to prevent the trigger block 232 from rotating.

[0061] In this way, through the trigger block 232 and the receiving cavity 221 configured as such, on the basis of ensuring the axial movement ability of the trigger block 232, the trigger block 232 can be effectively prevented from rotating circumferentially, and the constancy of the moving direction of the roller 233 can be ensured, thereby effectively improving the detection accuracy.

[0062] Since each contact switch 234 has a corresponding data transmission line, when several contact switches 234 are arranged at intervals along the axial direction of the receiving cavity 221, problems such as entanglement and interference of multiple data transmission lines may occur.

[0063] In view of this, in one embodiment of the present invention, several contact switches 234 of the present invention are arranged at intervals along the axial direction of the receiving cavity 221 in the receiving cavity 221, and several contact switches 234 are arranged at intervals along the circumferential direction of the receiving cavity 221.

[0064] In this way, the data transmission lines corresponding to several contact switches 234 can be respectively arranged at intervals along the axial and circumferential directions of the receiving cavity 221 in the mounting block 22, thereby effectively avoiding the entanglement or interference of the connection lines of several contact switches 234.

[0065] In one embodiment of the present invention, as Figure 3 shown, several contact switches 234 of the present invention can be arranged in a spiral form in the receiving cavity 221.

[0066] In this way, first, a plurality of contact switches 234 distributed in a spiral shape can enable the data transmission lines corresponding to the plurality of contact switches 234 to be arranged at intervals along the circumferential direction of the accommodation cavity 221 and be synchronously connected to the control unit along the axial direction of the accommodation cavity 221, which can effectively ensure the relative independence of the data transmission lines, avoid winding or interference with each other, and also facilitate the wiring of the data transmission lines within the mounting block 22.

[0067] Second, there is a sufficiently large distance between the plurality of contact switches 234 distributed in a spiral shape (whether in the circumferential or axial direction of the accommodation cavity 221), which can enable the moving distance of the trigger block 232 to be accurately reflected by the corresponding unique contact switch 234. This can not only effectively reduce the number of arranged trigger switches, save the arrangement cost and reduce the arrangement difficulty, but also avoid false alarms or synchronous triggering (or release) of the trigger switches, thereby effectively ensuring the triggering effectiveness of the trigger switches and further ensuring the accuracy of the detection results.

[0068] The above is only the specific implementation manner of the present invention, but the protection scope 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 protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
