Description

Technical Field

[0001] The present application relates to the technical field of construction engineering measurement, and in particular to a construction engineering wall sag detection device. Background Art

[0002] In construction projects, wall verticality detection is an important indicator to ensure building quality. Traditional wall verticality detection usually relies on manual measurement tools, such as plumb lines, tape measures, or laser levels. These tools are easy to operate, but because the detection process requires manual operation, they are not only inefficient, but the measurement results are also easily affected by human errors. Especially in the process of large-area wall detection, manual measurement is often time-consuming and laborious, and the data is not accurate enough, which makes it difficult to meet the requirements of high-precision detection in the modern construction industry.

[0003] Although existing wall verticality detection tools have achieved measurement automation to a certain extent, such as laser levels and total stations, these still need to be manually carried back and forth in each compartment on the same floor, and they need to be recalibrated and debugged each time they are moved, which also has the problem of low detection efficiency. Summary of the invention

[0004] In order to improve the measurement accuracy and efficiency of wall verticality, the present application provides a construction engineering wall verticality detection device.

[0005] The present application provides a construction engineering wall verticality detection device adopts the following technical solution: A verticality detection device for a wall surface of a construction project comprises an automatic walking trolley, a telescopic component is installed on the automatic trolley, a mounting plate is provided on the telescopic component, a fixing sleeve is provided on the mounting plate, a spring is provided in the fixing sleeve, a telescopic rod is inserted in the fixing sleeve, the spring is connected to the telescopic rod, the telescopic rod is rotatably connected to a roller, the rotating shaft of the roller is parallel to the ground, a first displacement sensor is installed in the fixing sleeve, the first displacement sensor is used to detect the distance between the telescopic rod and the bottom wall of the fixing sleeve, a second displacement sensor is installed on the mounting plate, the second displacement sensor is used to detect the distance between the mounting plate and the automatic walking trolley, and a data collection image generation module is provided in the automatic walking trolley, the data collection image generation module is used to collect data detected by the first displacement sensor and the second displacement sensor, and generate a two-dimensional coordinate graph.

[0006] By adopting the above technical solution, the automatic walking trolley automatically moves along the preset route. When the wall is detected, the automatic walking trolley approaches the wall to be tested, so that the roller is against the wall, and the telescopic component drives the mounting plate to move vertically. When the telescopic component is started, the first displacement sensor and the second displacement sensor start to detect data, and the data collection image generation module collects data and generates icons and transmits them to the terminal for viewing. The first displacement sensor records the displacement change between the fixed sleeve and the telescopic rod in real time, and the second displacement sensor records the height change of the mounting plate relative to the automatic trolley. The output data of the two sensors are mapped to a coordinate system, with the X axis representing the height data recorded by the second displacement sensor and the Y axis representing the displacement data recorded by the first displacement sensor. If the verticality of the wall is high, the data points in the coordinate system should be approximately a straight line; if the wall is tilted, the data points will deviate from the straight line to form an inclined trend line. By analyzing the maximum and minimum values ​​of the Y coordinate (ignoring the abnormal values ​​caused by local protrusions or depressions of the wall), the verticality deviation of the wall can be calculated. By detecting the position of each wall, it can be concluded whether the overall verticality of the wall meets the construction requirements.

[0007] This technical solution uses an automatic walking trolley to detect the verticality of the wall. It does not require manual operation and can continuously and automatically move along the wall surface to complete the measurement task, thus improving the detection efficiency. Through precise first and second displacement sensors, the solution can capture subtle tilts or unevenness of the wall and monitor the verticality of the wall in real time. This automated and continuous measurement method avoids the errors that occur in traditional manual measurement, and the measurement results are more accurate and reliable; The measurement data can be directly converted into a two-dimensional coordinate diagram to clearly show the verticality of the wall. Users can view the measurement results in real time, which is convenient for timely judgment of whether the wall is tilted or has other problems, reducing the workload of later data processing and improving the convenience of operation.

[0008] Optionally, the mounting plate is provided with a plurality of fixing sleeves along its length direction, and the first displacement sensor is independently installed in each of the fixing sleeves.

[0009] By adopting the above technical solution, since multiple rollers are in contact with the wall and measure at the same time, the system can sample multiple vertical positions of the wall at the same time and generate multiple charts. This synchronous multi-point measurement method makes the verticality analysis of the local area of ​​the wall more accurate and comprehensive.

[0010] Optionally, the data collection image generation module includes a data acquisition module, a data processing module, an image processing module and a wireless communication module. The data acquisition module is used to transmit the output data of the first and second displacement sensors in real time, the data processing module is used to process the data collected by the sensors, the image processing module converts the processed data into a visual chart, and the wireless communication module is used to transmit the generated image to the terminal device.

[0011] Optionally, an electromagnet is installed in the fixing sleeve, and the electromagnet is used to adsorb the telescopic rod so that it is completely extended into the fixing sleeve.

[0012] By adopting the above technical solution, when the detection of the first measurement area of ​​a wall is completed, the electromagnet can be started, and the electromagnet drives the telescopic rod to extend into the fixed sleeve, so that the roller is separated from the wall, and then the automatic walking trolley is directly moved horizontally to move the roller to the second measurement area. At this time, the electromagnet is turned off again, and the roller can be re-contacted with the wall. Therefore, when a wall needs to be divided into multiple measurement areas, after the measurement of one area is completed, the roller can be directly moved horizontally to another area, and the automatic walking trolley does not need to move away from the wall first, then move horizontally and then approach another measurement area of ​​the wall, and there is no need to retract the telescopic component every time and then expand it to another measurement area, which simplifies the design route and control program of the automatic walking trolley, and at the same time, avoids the roller directly moving horizontally against the wall, resulting in roller wear and inaccurate measurement.

[0013] Optionally, two third displacement sensors are installed at each end of the automatic walking vehicle, and the two third displacement sensors at the same end of the automatic walking vehicle are located on both sides of the automatic walking vehicle.

[0014] By adopting the above technical solution, the telescopic component will only be activated when the values ​​collected by the two third displacement sensors are the same and reach the designed values. This is to ensure the parallelism of the trolley and the wall, thereby ensuring that each roller can fit the wall for measurement.

[0015] Optionally, the telescopic assembly includes a fixed frame, which is arranged on the automatic walking trolley, and a first-level telescopic frame is provided in the fixed frame, a second-level telescopic frame is provided in the first-level telescopic frame, and a third-level telescopic frame is provided in the second-level telescopic frame. The fixed frame, the first-level telescopic frame, the second-level telescopic frame and the third-level telescopic frame are all connected by a linkage. The automatic walking trolley is provided with a driving member for driving the first-level telescopic frame to rise and fall. When the first-level telescopic frame is raised or lowered, the linkage drives the second-level telescopic frame to extend out of the first-level telescopic frame, and drives the third-level telescopic frame to extend out of the second-level telescopic frame. The mounting plate is fixed on the third-level telescopic frame.

[0016] By adopting the above technical solution, the multi-stage telescopic frame adopts a nested design, so that the entire telescopic assembly occupies very little space in the initial state, which is convenient for walking on the construction site. When measurement is required, the telescopic frame can be extended step by step, providing a larger telescopic range and achieving a larger vertical measurement height.

[0017] Optionally, the driving member includes a first motor, which is mounted on the automatic walking trolley, the motor is connected to a lead screw, and the bottom rod is threadedly connected to the first-level telescopic frame.

[0018] Optionally, the linkage includes a primary rack, a secondary rack, a tertiary rack and a fourth rack, the primary rack being arranged on the fixed frame, the secondary rack being arranged on the primary telescopic frame, the tertiary rack being arranged on the secondary telescopic frame, the fourth rack being arranged on the tertiary telescopic frame, the primary telescopic frame being rotatably connected to a primary gear, the primary gear being meshed with the primary rack and the tertiary rack at the same time, the secondary telescopic frame being rotatably connected to a secondary gear, the secondary gear being meshed with the secondary rack and the fourth rack at the same time.

[0019] By adopting the above technical solution, when the first-level telescopic frame rises, the first-level rack drives the first-level gear to rotate, and the first-level gear drives the third-level rack to rise, so that the second-level telescopic frame rises and extends out of the first-level telescopic frame, and because there is a relative displacement between the second-level telescopic frame and the first-level telescopic frame, the second-level rack drives the second-level gear to rotate, and the second-level gear drives the fourth-level rack to rise, so that the third-level telescopic frame extends out of the second-level telescopic frame, thereby realizing the synchronous extension of the first-level telescopic frame, the second-level telescopic frame and the third-level telescopic frame.

[0020] Optionally, a flip assembly is provided on the automatic walking trolley, and the flip assembly is connected to a flip plate. There are two telescopic assemblies, and the two telescopic assemblies are installed on the flip plate. Each telescopic assembly is respectively connected to a mounting plate, and the telescopic rod is perpendicular to the flip plate. The flip assembly can control the flip plate to flip to a horizontal state, and can also make the flip plate flip around its own two ends. The extension directions of the two groups of telescopic assemblies are opposite.

[0021] By adopting the above technical solution, when one wall is inspected, the trolley can directly retreat to the other wall. Then the flip plate is reversed, and another set of telescopic components drives another set of rollers to measure, without the need for the trolley to turn around, which greatly reduces the time of trolley movement and the complexity of path optimization, thereby improving measurement efficiency.

[0022] Optionally, the telescopic assembly includes a mounting frame, the mounting frame is mounted on the automatic walking trolley, a second motor is mounted on one side of the mounting frame, the second motor is connected to a rotating shaft, the mounting frame is symmetrically arranged about the rotating shaft, both ends of the rotating shaft are connected to a first connecting rod, the first connecting rod is hinged to a second connecting rod, two second connecting rods are hinged to the flip plate together, and the second connecting rods are located in the middle of the side of the flip plate, both ends of the flip plate are provided with rotating columns, and support blocks are provided at the four corners of the mounting frame, the support blocks are provided with rotating grooves, the rotating columns can be placed on the rotating grooves, and the support blocks are also provided with limiting sleeves; The mounting frame is provided with a rodless electric cylinder, the rodless electric cylinder is connected with a transverse rod, both ends of the transverse rod are provided with connecting plates, both ends of the connecting plate are provided with plug-in plates, and the plug-in plates correspond to the limit sleeves one by one; When the rotating column at one end of the flip plate is placed in the corresponding rotating groove, and the plug-in plate on the same side of the flip plate is pressed on the corresponding rotating column, the plug-in plate at the other end of the transverse rod is staggered with the rotating groove at the other end of the mounting frame.

[0023] By adopting the above technical solution, when measurement is not required, the flip plate can be placed in a horizontal state, and the telescopic component can be placed flat on the automatic walking trolley, which is beneficial to reduce the occupied space and reduce the probability of the telescopic component of the automatic walking trolley colliding with obstacles when the automatic walking trolley is moving.

[0024] When the flip plate needs to be rotated, the rodless electric cylinder drives the lateral rod to move, and the lateral rod drives the connecting plate to move. The connecting plate at one end drives the corresponding plug-in plate to pass through the limit slot and press the plug-in plate on the rotating column at one end of the flip plate. The connecting plate at the other end is away from the mounting frame, so that the plug-in plate at the other end is staggered with the rotating slot at the other end of the mounting frame, so that the rotating column at the other end can leave the rotating slot. Then start the second motor, and the second motor drives the rotating shaft to rotate. With the cooperation of the first connecting rod, the second connecting rod and the rotating column, the rotation of the flip plate can be realized. If the flip plate needs to be flipped around the rotating column at the other end, it is only necessary to adjust the flip plate to a horizontal state, and then the rodless cylinder controls the plug-in plate at the other end to press on the rotating column at the other end of the flip plate.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. This technical solution uses an automatic walking trolley to detect the verticality of the wall. It does not require manual operation and can continuously and automatically move along the wall surface and complete the measurement task, thus improving the detection efficiency; 2. Through the measurement of the first displacement sensor and the second displacement sensor, it is possible to capture the slight tilt or unevenness of the wall and monitor the verticality of the wall in real time. This automated and continuous measurement method avoids the errors that occur in traditional manual measurement, and the measurement results are more accurate and reliable; 3. The measurement data can be directly converted into a two-dimensional coordinate diagram to clearly show the verticality of the wall. Users can view the measurement results in real time, which is convenient for timely judgment of whether the wall is tilted or has other problems, reducing the workload of later data processing and improving the convenience of operation.

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-5This application is described in further detail.

[0033] The embodiment of the present application discloses a device for detecting the verticality of a wall surface in a construction project.

[0034] like Figure 1 , Figure 2 and Figure 3 The verticality detection equipment for the wall of a construction project comprises an automatic walking trolley 1, a flip assembly 2 is arranged on the top of the automatic walking trolley 1, the flip assembly 2 is connected to a flip plate 3, two telescopic assemblies 4 are installed on the flip plate 3, and the extension direction of the two telescopic assemblies 4 is such that when the flip plate 3 is in a horizontal state, the two telescopic assemblies 4 extend toward one end of the automatic walking trolley 1 respectively. Each telescopic assembly 4 is connected to a mounting plate 5, and a plurality of fixing sleeves 51 are arranged along the length direction of the mounting plate 5, a spring 52 is connected to the inner bottom wall of the fixing sleeve 51, a telescopic rod 53 is inserted in the fixing sleeve 51, and the telescopic rod 53 is connected to the spring 52. One end of the telescopic rod 53 extending out of the fixing sleeve 51 is rotatably connected to a roller 54, and when the flip plate 3 is in a vertical state, the rotating shaft of the roller 54 is parallel to the ground.

[0035] The inner bottom wall of the fixing sleeve 51 is also installed with a first displacement sensor 55 and an electromagnet 56, the bottom of the mounting plate 5 is installed with a second displacement sensor 57, and the data collection image generation module 6 is arranged in the automatic walking vehicle 1. Two third displacement sensors 11 are installed at both ends of the automatic walking vehicle 1, and the two third displacement sensors 11 at the same end of the automatic walking vehicle 1 are respectively located on both sides of the automatic walking vehicle 1.

[0036] The first displacement sensor 55 is used to detect the distance between the telescopic rod 53 and the bottom wall of the fixing sleeve 51, the second displacement sensor 57 is used to detect the distance between the mounting plate 5 and the self-propelled vehicle 1, and the data collection image generation module 6 is used to collect the data detected by the first displacement sensor 55 and the second displacement sensor 57 and generate a two-dimensional coordinate map. The third displacement sensor 11 is used to detect the distance between the self-propelled vehicle 1 and the wall.

[0037] The automatic walking trolley 1 automatically moves along the preset route. When the wall is detected, the flip assembly 2 drives the flip plate 3 to flip toward the end of the automatic walking trolley 1 close to the wall. The automatic walking trolley 1 approaches the wall to be tested, so that the roller 54 is against the wall. The telescopic assembly 4 drives the mounting plate 5 to move vertically. When the telescopic assembly 4 is started, the first displacement sensor 55 and the second displacement sensor 57 start to detect data. The data collection image generation module 6 collects data and generates icons and transmits them to the terminal for viewing. The first displacement sensor 55 records the displacement change between the fixed sleeve 51 and the telescopic rod 53 in real time, and the second displacement sensor 57 records the height change of the mounting plate 5 relative to the automatic trolley. The output data of the two sensors are mapped to a coordinate system, with the X axis representing the height data recorded by the second displacement sensor 57 and the Y axis representing the displacement data recorded by the first displacement sensor 55. If the verticality of the wall is high, the data points in the coordinate system should be approximately a straight line; if the wall is tilted, the data points will deviate from the straight line to form an inclined trend line. By analyzing the maximum and minimum values ​​of the Y coordinate (ignoring abnormal values ​​caused by local protrusions or depressions of the wall), the verticality deviation of the wall can be calculated.

[0038] Furthermore, since multiple rollers 54 are in contact with the wall and measuring at the same time, the system can sample multiple vertical positions of the wall at the same time and generate multiple charts. This synchronous multi-point measurement method makes the verticality analysis of the local area of ​​the wall more accurate and comprehensive.

[0039] After the measurement of one area of ​​the wall is completed, the electromagnet 56 is started, and the electromagnet 56 drives the telescopic rod 53 to extend into the fixed sleeve 51, so that the roller 54 is separated from the wall, and then the automatic walking trolley 1 is directly moved horizontally to move the roller 54 to the second measurement area. At this time, the electromagnet 56 is turned off again, and the roller 54 can be re-contacted with the wall. There is no need for the automatic walking trolley 1 to first move away from the wall, then move horizontally and then approach another measurement area of ​​the wall, and there is no need for the telescopic component 4 to be retracted each time and then unfolded to another measurement area, which simplifies the design route and control program of the automatic walking trolley 1, and at the same time, avoids the roller 54 from moving horizontally directly against the wall, resulting in the wear of the roller 54 and the measurement being inaccurate.

[0040] Moreover, the telescopic component 4 will only be activated when the values ​​collected by the two third displacement sensors 11 are the same and reach the designed values. This is to ensure the parallelism between the automatic walking vehicle 1 and the wall, thereby ensuring that each roller 54 can fit the wall for measurement.

[0041] At the same time, when the detection of one wall is completed, the trolley can directly back up to the other wall. Then the flip assembly 2 drives the flip plate 3 to reverse, so that the flip plate 3 flips toward the direction close to the other wall, and another set of telescopic components 4 drives another set of rollers 54 to measure, without the need for the trolley to turn around, which greatly reduces the moving time of the automatic walking trolley 1 and the complexity of path optimization, thereby improving the measurement efficiency.

[0042] This technical solution uses an automatic walking trolley 1 to detect the verticality of the wall. It does not require manual operation and can continuously and automatically move along the surface of the wall and complete the measurement task, thereby improving the detection efficiency. Through the measurement of the first displacement sensor 55 and the second displacement sensor 57, it is possible to capture the slight tilt or unevenness of the wall and monitor the verticality of the wall in real time. This automated and continuous measurement method avoids the errors that occur in traditional manual measurements, and the measurement results are more accurate and reliable. The measurement data can be directly converted into a two-dimensional coordinate diagram to clearly display the verticality of the wall. The user can view the measurement results in real time, which is convenient for timely judgment of whether the wall has tilt or other problems, reducing the workload of later data processing and improving the convenience of operation.

[0043] like Figure 2 The data collection image generation module 6 includes a data acquisition module 61, a data processing module 62, an image processing module 63 and a wireless communication module 64. The data acquisition module 61 is used to transmit the output data of the first displacement sensor 55 and the second displacement sensor 57 in real time. The data processing module 62 is used to process the data collected by the first displacement sensor 55 and the second displacement sensor 57. The image processing module 63 converts the processed data into a visual chart. The wireless communication module 64 is used to transmit the generated image to the terminal device.

[0044] The data acquisition module 61 transmits the output data of the first displacement sensor 55 and the second displacement sensor 57 to the control system in real time; The data processing module 62 may be an embedded computing module (such as a single chip microcomputer or FPGA), which processes the data collected by the sensor through the embedded computing module (such as a single chip microcomputer or FPGA), including removing noise and abnormal values, performing curve fitting, and calculating the verticality deviation of the wall; The image processing module 63 can convert the processed data into a visual chart (such as an XY curve chart) by designing an algorithm to intuitively display the change of the verticality of the wall. The image can be generated using a simple graphics processing tool or an embedded library (such as Matplotlib, OpenCV); The wireless communication module 64 may be integrated with a Wi-Fi, Bluetooth or 5G communication module for transmitting the processed data or generated images to a terminal device (such as a computer or mobile device) in real time.

[0045] like Figure 4 and Figure 5 The telescopic assembly 4 includes a fixed frame 41, which is bolted to the flip plate 3. A first-level telescopic frame 42 is sleeved in the fixed frame 41, a second-level telescopic frame 43 is sleeved in the first-level telescopic frame 42, and a third-level telescopic frame 44 is sleeved in the second-level telescopic frame 43. The fixed frame 41, the first-level telescopic frame 42, the second-level telescopic frame 43 and the third-level telescopic frame 44 are all connected by a linkage 7. A driving member 8 for driving the first-level telescopic frame 42 to move is provided on the flip plate 3. When the first-level telescopic frame 42 is lifted or lowered, the linkage 7 drives the second-level telescopic frame 43 to extend out of the first-level telescopic frame 42, and drives the third-level telescopic frame 44 to extend out of the second-level telescopic frame 43. The mounting plate 5 is bolted to the third-level telescopic frame 44.

[0046] The driving member 8 includes a first motor 81, which is mounted on the fixing frame 41. The first motor 81 is connected to a lead screw 82, which is threadedly connected to the primary telescopic frame 42; The linkage 7 includes two primary racks 71, two secondary racks 72, two tertiary racks 73 and two quaternary racks 74. The two primary racks 71 are respectively fixed on the two inner side walls of the fixed frame 41, and the two primary racks 71 are staggered. The two secondary racks 72 are arranged on the two inner side walls of the primary telescopic frame 42, and the two secondary racks 72 are staggered. The two tertiary racks 73 are arranged on the two outer side walls of the secondary telescopic frame 43, and the two tertiary racks 73 are staggered. The primary racks 71 and the tertiary racks 73 on the same side are arranged opposite to each other. The two quaternary racks 74 are arranged on the two outer side walls of the tertiary telescopic frame 44, and the two quaternary racks 74 are staggered. The secondary racks 72 and the quaternary racks 74 on the same side are arranged opposite to each other. The first-stage telescopic frame 42 is rotatably connected to the two sides with a first-stage gear 75, which is simultaneously meshed with the first-stage rack 71 and the third-stage rack 73 on the same side. The second-stage telescopic frame 43 is rotatably connected to the two sides with a second-stage gear 76, which is simultaneously meshed with the second-stage rack 72 and the fourth-stage rack 74 on the same side.

[0047] The multi-stage telescopic frame is designed in a nested manner, so that the entire telescopic assembly 4 takes up very little space in the initial state, which is convenient for walking on the construction site. When measurement is required, the telescopic frame can be extended step by step, providing a larger telescopic range and achieving a larger vertical measurement height.

[0048] During lifting, the first motor 81 drives the lead screw 82 to rotate, so that the first-level telescopic frame 42 rises. When the first-level telescopic frame 42 rises, the first-level rack 71 drives the first-level gear 75 to rotate, and the first-level gear 75 drives the third-level rack 73 to rise, so that the second-level telescopic frame 43 rises and extends out of the first-level telescopic frame 42. Since there is a relative displacement between the second-level telescopic frame 43 and the first-level telescopic frame 42, the second-level rack 72 drives the second-level gear 76 to rotate, and the second-level gear 76 drives the fourth-level rack 74 to rise, so that the third-level telescopic frame 44 extends out of the second-level telescopic frame 43, thereby realizing the synchronous extension of the first-level telescopic frame 42, the second-level telescopic frame 43 and the third-level telescopic frame 44.

[0049] like Figure 1 The flip assembly 2 includes a mounting frame 21, which is mounted on the top of the automatic walking vehicle 1. A second motor 22 is mounted on one side of the mounting frame 21. The second motor 22 is connected to a rotating shaft 23. The rotating shaft 23 is rotatably connected to the mounting frame 21. The mounting frame 21 is symmetrically arranged about the rotating shaft 23. Both ends of the rotating shaft 23 are connected to a first connecting rod 24. The end of the first connecting rod 24 is hinged to a second connecting rod 25. The two second connecting rods 25 are hinged to the flip plate 3 together. The second connecting rod 25 is hinged to the side of the flip plate 3, and the second connecting rod 25 is located in the middle of the side of the flip plate 3. Both ends of the flip plate 3 are fixed with rotating columns 31, and the rotating columns 31 extend from both sides of the flip plate 3. The four corners of the mounting frame 21 are provided with support blocks 26. The top surface of the support block 26 is provided with a rotation groove 261. The rotation groove 261 is a semicircular arc groove. The rotation column 31 can be placed on the rotation groove 261 and fit therewith. The support block 26 is also fixed with a limiting sleeve 27. The limiting sleeve 27 corresponds to the rotation groove 261 one by one. The limiting sleeve 27 is arranged adjacent to the rotation groove 261. A rodless electric cylinder 28 is provided on the mounting frame 21, and the rodless electric cylinder 28 is connected to a transverse rod 29, which passes through the bottom of the rotating shaft 23, and the transverse rod 29 and the rotating shaft 23 are perpendicular to each other, and connecting plates 210 are installed at both ends of the transverse rod 29, and the connecting plates 210 and the transverse rod 29 are perpendicular to each other, and plug-in plates 211 are provided at both ends of the connecting plate 210, and the plug-in plates 211 correspond to the limit sleeves 27 one by one; When the rotating column 31 at one end of the flip plate 3 is placed in the corresponding rotating groove 261, and the plug-in plate 211 at one end of the flip plate 3 is pressed on the corresponding rotating column 31, the plug-in plate 211 at the other end of the transverse rod 29 is staggered with the rotating groove 261 at the other end of the mounting frame 21.

[0050] When measurement is not required, the flip plate 3 can be placed in a horizontal state, and the telescopic component 4 can be placed flat on the automatic walking vehicle 1, which is beneficial to reduce the occupied space and can reduce the probability of the telescopic component 4 colliding with obstacles when the automatic walking vehicle 1 is moving.

[0051] When the flip plate 3 needs to be rotated, the rodless electric cylinder 28 drives the lateral rod 29 to move, and the lateral rod 29 drives the connecting plate 210 to move. The connecting plate 210 at one end drives the corresponding plug-in plate 211 to pass through the limiting sleeve 27 and press the plug-in plate 211 on the rotating column 31 at one end of the flip plate 3. The connecting plate 210 at the other end is away from the mounting frame 21, so that the plug-in plate 211 at the other end is staggered with the rotating groove 261 at the other end of the mounting frame 21, so that the rotating column 31 at the other end can leave the rotating groove 261. Then the second motor 22 is started, and the second motor 22 drives the rotating shaft 23 to rotate. Under the cooperation of the first connecting rod 24, the second connecting rod 25 and the rotating column 31, the rotation of the flip plate 3 can be realized. If the flip plate 3 needs to be flipped around the rotating column 31 at the other end, it is only necessary to adjust the flip plate 3 to a horizontal state, and then the rodless cylinder controls the plug-in plate 211 at the other end to press on the rotating column 31 at the other end of the flip plate 3.

[0052] The implementation principle of the embodiment of the present application is as follows: the automatic walking trolley 1 automatically moves along a preset route. When performing wall detection, the automatic walking trolley 1 approaches the wall to be tested, so that the roller 54 is against the wall, and the telescopic component 4 drives the mounting plate 5 to move vertically. When the telescopic component 4 is started, the first displacement sensor 55 and the second displacement sensor 57 start to detect data, and the data collection image generation module 6 collects data and generates icons and transmits them to the terminal for viewing. The first displacement sensor 55 records the displacement change between the fixed sleeve 51 and the telescopic rod 53 in real time, and the second displacement sensor 57 records the height change of the mounting plate 5 relative to the automatic walking trolley 1. The output data of the two sensors are mapped to a coordinate system, with the X axis representing the height data recorded by the second displacement sensor 57 and the Y axis representing the displacement data recorded by the first displacement sensor 55. If the verticality of the wall is high, the data points in the coordinate system should be approximately a straight line; if the wall is tilted, the data points will deviate from the straight line to form an inclined trend line. By analyzing the maximum and minimum values ​​of the Y coordinate (ignoring the abnormal values ​​caused by local protrusions or depressions of the wall), the verticality deviation of the wall can be calculated. By checking the position of each wall, it can be determined whether the overall verticality of the wall meets the construction requirements.

[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
