Description

Technical Field

[0001] The present application relates to the technical field of building detection equipment, and in particular to a wall surface flatness detection device and detection method. Background Art

[0002] During the manufacturing and installation of large membrane tanks, a concrete support base is usually required at the bottom of the membrane tank to provide a stable and reliable load-bearing foundation. Due to the large size and high center of gravity of the membrane tank structure, the operational stability of the membrane tank depends on the flatness and levelness of the bottom support structure. Traditional flatness detection relies on manual visual inspection and simple tools, which is time-consuming and difficult to achieve efficient and accurate judgment of local concave or convex areas. There are also problems such as complex operation, unclear feedback, and large errors. Summary of the Invention

[0003] In order to improve the defects of existing detection devices that are difficult to adapt to the concave and convex structure of the supporting bottom plate of the film tank during the flatness detection process, resulting in low detection efficiency and large detection errors, the present application provides a wall flatness detection device and detection method.

[0004] The present application provides a wall surface flatness detection device and detection method using the following technical solutions:

[0005] A wall surface flatness detection device comprises a detection device body, a first telescopic detection mechanism movably inserted at one end of the detection device body, a second telescopic detection mechanism movably inserted at the other end of the detection device body and arranged corresponding to the first telescopic detection mechanism, a synchronous gear mechanism inserted at a middle position of the detection device body and meshing with the first telescopic detection mechanism and the second telescopic detection mechanism, a first detection limit mechanism connected to an end of the first telescopic detection mechanism, a second detection limit mechanism connected to an end of the second telescopic detection mechanism, a groove flatness detection mechanism provided on a side wall of the detection device body and used to be inserted into a groove on the wall surface, an elastic pressing mechanism inserted in the detection device body and used to push the first telescopic detection mechanism and the second telescopic detection mechanism to move in a direction away from each other, a telescopic locking mechanism connected to both side walls of the detection device body and used to be inserted on the first telescopic detection mechanism and the second telescopic detection mechanism, and a bubble level connected to the side wall of the detection device body;

[0006] The first detection limit mechanism, the first telescopic detection mechanism, the detection device body, the second telescopic detection mechanism and the second detection limit mechanism are arranged to form a protrusion flatness detection groove for inserting the wall protrusion, and the groove flatness detection mechanism extends in a direction opposite to the opening direction of the protrusion flatness detection groove; the groove flatness detection mechanism includes a detection mechanism body connected to the middle position of the detection device body, a detection mechanism telescopic component movably inserted in the detection mechanism body, a telescopic limit rack provided on the detection mechanism telescopic component and arranged along the length direction of the detection mechanism telescopic component, and a telescopic locking component provided on the detection mechanism body and used to be plugged into and cooperated with the telescopic limit rack.

[0007] By adopting the above technical solution, when detecting the flatness of the groove, the groove flatness detection mechanism is inserted into the groove to be detected, and the detection device body is adjusted to a horizontal state by a bubble level to ensure that the detection reference is consistent; after the telescopic locking mechanism is released, the elastic pressing mechanism releases the elastic force, and respectively pushes the first telescopic detection mechanism and the second telescopic detection mechanism to move in directions away from each other, and the symmetrical and synchronous extension of the first telescopic detection mechanism and the second telescopic detection mechanism on both sides is achieved through the synchronous gear mechanism located in the middle of the detection device body, ensuring structural balance and symmetrical detection position; with the synchronous movement of the first telescopic detection mechanism and the second telescopic detection mechanism, the first detection limit mechanism and the second detection limit mechanism also move synchronously, when the first detection When the limiting mechanism and the second detection limiting mechanism contact the wall, the groove depth is too large and the flatness is unqualified. When the first detection limiting mechanism and the second detection limiting mechanism move to the preset position and do not contact the wall, the groove depth is too small and the flatness is qualified. When detecting the flatness of the protrusion, the protruding part of the wall is inserted into the protrusion flatness detection groove. When the first detection limiting mechanism and the second detection limiting mechanism contact the wall, the flatness is qualified. When the first detection limiting mechanism and the second detection limiting mechanism maintain a gap with the wall, the flatness of the wall protrusion is unqualified. The present application realizes the rapid and efficient detection of the concave and convex areas of the wall surface of the supporting bottom plate of the film tank, effectively improves the detection accuracy, reduces the difficulty of operation, and adapts to the rapid determination of the flatness of complex structures.

[0008] Preferably, the elastic pressing mechanism includes a first pushing component located on one side of the synchronous gear mechanism and used to press the first telescopic detection mechanism to move in a direction away from the second telescopic detection mechanism, and a second pushing component located on the other side of the synchronous gear mechanism and used to press the second telescopic detection mechanism to move in a direction away from the first telescopic detection mechanism;

[0009] The first pushing assembly and the second pushing assembly both include a pressing guide component inserted into the detection device body, and an elastic pressing member inserted into the pressing guide component. The pressing guide component is provided with a telescopic guide groove, and the elastic pressing member is inserted into the telescopic guide groove.

[0010] By adopting the above technical solution, the telescopic guide groove is used to limit the movement path of the elastic top pressure piece, ensuring that the elastic top pressure piece stably releases the driving force in the axial direction. When the telescopic locking mechanism is in the released state, the two elastic top pressure pieces respectively push the first telescopic detection mechanism and the second telescopic detection mechanism to extend synchronously along the opening direction of the corresponding telescopic guide groove after compression release, and ensure the consistency of movement on both sides through the meshing action with the synchronous gear mechanism; the present application provides driving force through elastic release, and cooperates with the guide structure to ensure the accuracy of the movement trajectory. It not only has a fast response and a compact structure, but also can be automatically deployed without external drive, effectively improving the convenience of the telescopic operation of the detection device in actual application and the consistency of the detection benchmarks on both sides, thereby enhancing the adaptability and accuracy of the overall device in the flatness detection of concave and convex structures.

[0011] Preferably, the first telescopic detection mechanism and the second telescopic detection mechanism each include a telescopic rack assembly movably inserted in the telescopic guide groove and meshing with the synchronous gear mechanism, a guide connecting protrusion connected to the telescopic rack assembly, a telescopic detection assembly movably inserted in the telescopic guide groove and connected to the guide connecting protrusion, a detection extension assembly movably inserted in the telescopic detection assembly along the length direction of the telescopic detection assembly, and a telescopic limit assembly inserted in the telescopic detection assembly and the detection extension assembly;

[0012] The telescopic detection component is inserted into the telescopic guide groove, and the elastic pressing member is located between the telescopic detection component and the pressing guide member.

[0013] By adopting the above technical solution, the telescopic detection component can extend outward along the telescopic guide groove under the push of the elastic top pressure piece, driving the first telescopic detection mechanism and the second telescopic detection mechanism to expand symmetrically and synchronously. The end of the telescopic rack assembly is connected to the guide connecting convex edge to ensure force transmission and positioning accuracy during structural movement. The detection extension assembly is used to adjust the length of the detection end to adapt to different wall detection depth and width requirements. The telescopic detection component and the detection extension assembly are used to limit the maximum extension distance through the telescopic limit assembly to prevent over-travel displacement or structural interference. During the entire movement process of this application, the elastic top pressure piece is located between the top pressure guide component and the telescopic detection assembly. When the elastic force is released, the telescopic detection assembly is pushed to move smoothly outward, forming a synchronous expansion of the detection end, and adaptive length adjustment is performed through the detection extension assembly. This application realizes adaptive extension, precise positioning and structural symmetrical synchronization of the detection end through multi-stage sliding fit and meshing limit design, thereby improving the adaptability of the device to different wall concave and convex structures, effectively reducing the complexity of the detection operation and ensuring the judgment accuracy.

[0014] Preferably, the pressing guide component is provided with a convex guide slot, and the guide connection convex edge is movably inserted into the convex guide slot.

[0015] By adopting the above technical solution, the guide connection convex edge is movably inserted in the convex edge guide groove. When the elastic top pressure member releases the driving force to push the telescopic detection assembly and the guide connection convex edge to move, the convex edge guide groove provides a precise motion trajectory restriction for the guide connection convex edge, ensuring that the guide connection convex edge slides smoothly along the predetermined straight line direction, effectively preventing lateral deviation, shaking or jamming, and at the same time improving the coordination consistency of the first telescopic detection mechanism and the second telescopic detection mechanism under the linkage of the synchronous gear mechanism. This application not only ensures the motion stability of the elastic push and detection end structure, but also improves the positioning accuracy and operational reliability of the overall detection device.

[0016] Preferably, the synchronous gear mechanism includes a rotating bearing sleeved on the periphery of the groove flatness detection mechanism, and a rotating gear sleeved on the periphery of the rotating bearing and connected to the rotating bearing;

[0017] The telescopic rack assembly includes a telescopic rack body and a telescopic transmission rack provided on one side of the telescopic rack body and meshing with the rotating gear. The end of the telescopic rack body is connected to the end of the guide connection protrusion.

[0018] By adopting the above technical solution, the rotating bearing is used to support the rotating gear to rotate smoothly around the central axis, and the rotating gear is engaged with the telescopic transmission racks on the left and right sides. The telescopic transmission rack is arranged on one side of the telescopic rack body, and the end of the telescopic rack body is connected to the end of the guide connecting convex edge, thereby forming a complete drive transmission chain; when the elastic top pressure piece pushes the telescopic detection assembly on either side to move, the pushing force of the elastic top pressure piece is transmitted to the telescopic rack body through the guide connecting convex edge, thereby driving the telescopic transmission rack to move along the telescopic direction, and the rotating gear is driven to rotate synchronously, and the rotating gear drives the telescopic rack assembly on the other side to achieve synchronous reverse movement; the present application realizes the symmetrical and synchronous deployment of the telescopic detection mechanisms on both sides through the gear and rack linkage method, which not only improves the coordination and structural symmetry of the detection action, but also avoids the offset error caused by unilateral push, thereby effectively improving the consistency of the limit reference during the wall flatness detection process and the accuracy of the detection results.

[0019] Preferably, the telescopic rack assembly further comprises a telescopic locking rack provided on the other side of the telescopic rack body and symmetrically arranged with the telescopic transmission rack; a locking through hole is provided on the detection device body;

[0020] The telescopic locking mechanism includes a toggle flip shaft inserted in the locking through hole and connected to the detection device body, a toggle flip assembly hinged to the toggle flip shaft, a toggle cam connected to the toggle flip assembly and located on one side of the toggle flip assembly, a plug-in limit cam connected to the other side of the toggle flip assembly, and an elastic pressing assembly connected to the detection device body and located between the detection device body and the toggle cam; the elastic pressing assembly is used to press the toggle cam so that the plug-in limit cam is inserted into the locking through hole with the toggle flip shaft as the rotation axis, and is plugged into and matched with the telescopic locking rack.

[0021] By adopting the above technical solution, the elastic pressing component provides elastic force to press the toggle convex edge, so that the toggle flip component rotates around the toggle flip axis, so that the plug-in limit convex edge is inserted into the locking through hole, and plugged into the telescopic locking rack to form a mechanical lock, preventing the first telescopic detection mechanism and the second telescopic detection mechanism from accidentally moving before detection or during transportation. When the first telescopic detection mechanism and the second telescopic detection mechanism need to be released, it is only necessary to press the toggle convex edge to overcome the elastic force of the elastic pressing component, drive the toggle flip component to rotate around the toggle flip axis, and realize the separation of the plug-in limit convex edge and the telescopic locking rack, thereby releasing the locked state. The present application realizes rapid locking and unlocking through mechanical linkage, ensuring that the detection device can maintain structural stability and easy operation during the standby or detection stage, thereby improving detection safety and reliability.

[0022] Preferably, the first detection limit mechanism and the second detection limit mechanism both include a limit mechanism body connected to the end of the detection extension assembly, a limit mechanism extension assembly movably inserted in the limit mechanism body, a movable limit rack provided on the limit mechanism extension assembly and arranged along the length direction of the limit mechanism extension assembly, and an extended limit assembly provided on the limit mechanism body and used for movably plugging and cooperating with the movable limit rack.

[0023] By adopting the above-mentioned technical solution, the detection extension assembly is used to drive the limit mechanism body to move outward to detect the flatness of the wall; the limit mechanism extension assembly is used to extend outward to adapt to different detection needs. When it is necessary to detect the flatness of different wall protrusions, the limit mechanism extension assembly is unlocked by extending the limit assembly, and the length of the extended limit assembly in the vertical direction relative to the detection extension assembly is adjusted. Multi-level positioning and stable limiting are achieved by mechanically plugging the moving limit rack and the extended limit assembly to prevent the limit end from retracting during detection operation or external force impact, thereby ensuring the repeatability and accuracy of each measurement. This application improves the adaptability of the wall flatness detection device to walls of different widths and structures through a modular, adjustable detection end and a multi-level plug-in limit design, thereby enhancing the reliability of the detection results and the convenience of operation.

[0024] Preferably, the detection mechanism body is provided with a locking sliding through hole aligned with the telescopic limiting rack;

[0025] The telescopic locking assembly includes an annular locking slide rail mounted on the outer side wall of the detection mechanism body, a rotating sliding component mounted on the annular locking slide rail and rotatably connected to the annular locking slide rail, a locking magnetic component connected to the rotating sliding component and used to align with the locking sliding through hole, an unlocking magnetic component, and a magnetic plug-in component movably inserted into the locking sliding through hole and used to be plugged into and cooperate with the telescopic limiting rack; the locking magnetic component and the magnetic poles of the magnetic plug-in component repel each other, and the unlocking magnetic component and the magnetic poles of the magnetic plug-in component attract each other.

[0026] By adopting the above technical solution, in the locked state, the rotating sliding component is rotated to align the locking magnetic component with the magnetic plug-in component, the magnetic poles repel each other, and the magnetic plug-in component is inserted into the tooth groove of the telescopic limit rack to achieve mechanical locking, thereby preventing the telescopic component of the detection mechanism from accidentally retracting or shifting; when adjustment or unlocking is required, the rotating sliding component is rotated to align the unlocking magnetic component with the magnetic plug-in component, the magnetic poles attract each other, the magnetic plug-in component is sucked out of the tooth groove, the locked state is released, and the length adjustment or component reset is achieved. The present application combines rotation control and magnetic action to achieve fast, low-wear, and highly reliable positioning locking and unlocking, thereby improving the flexibility, reliability and ease of operation of the detection mechanism during the detection of different groove depths, and effectively ensuring the consistency and accuracy of the measurement.

[0031] S4: When the first detection limit mechanism and the second detection limit mechanism move to the preset positions, the wall groove flatness is qualified;

[0032] When the first detection limit mechanism and the second detection limit mechanism are in contact with the wall surface, the flatness of the wall surface groove is unqualified;

[0033] S5: When detecting the flatness of the wall surface protrusion, pressing the telescopic locking mechanism to release the locking state of the first telescopic detection mechanism and the second telescopic detection mechanism;

The elastic top pressure mechanism releases the elastic force and pushes the telescopic detection mechanisms on both sides to expand synchronously in opposite directions, driving the first detection limit mechanism and the second detection limit mechanism to move. If the first telescopic detection mechanism and the second telescopic detection mechanism can move to the preset position and do not touch the wall surface, it is determined that the groove flatness is qualified.

If the first detection limit mechanism and the second detection limit mechanism are in contact with the wall surface measured around the protrusion, the flatness is judged to be qualified. If there is a gap, it is unqualified. The present application ensures the detection benchmark through the bubble level, and realizes efficient and accurate detection of concave and convex areas through mechanical linkage and limit contact.

[0054] The following is combined with Figures 1 to 9 This application is described in further detail.

[0055] The present application discloses a wall surface flatness detection device and detection method. Figures 1 to 3A wall flatness detection device comprises a detection device body 1, a first telescopic detection mechanism 2 movably inserted at one end of the detection device body 1, a second telescopic detection mechanism 3 movably inserted at the other end of the detection device body 1 and corresponding to the first telescopic detection mechanism 2, a synchronous gear mechanism 4 inserted at the middle position of the detection device body 1 and meshing with the first telescopic detection mechanism 2 and the second telescopic detection mechanism 3, a first detection limiting mechanism 5 connected to the end of the first telescopic detection mechanism 2, a second detection limiting mechanism 6 connected to the end of the second telescopic detection mechanism 3, a groove flatness detection mechanism 7 provided on the side wall of the detection device body 1 and used to be inserted into the wall groove, an elastic pressing mechanism 8 inserted in the detection device body 1 and used to push the first telescopic detection mechanism 2 and the second telescopic detection mechanism 3 to move in a direction away from each other, a telescopic locking mechanism 9 connected to the two side walls of the detection device body 1 and used to be inserted on the first telescopic detection mechanism 2 and the second telescopic detection mechanism 3, and a bubble level 10 connected to the side wall of the detection device body 1;

[0056] The first detection limit mechanism 5, the first telescopic detection mechanism 2, the detection device body 1, the second telescopic detection mechanism 3 and the second detection limit mechanism 6 are arranged to form a protrusion flatness detection groove 11 for inserting the wall protrusion, and the groove flatness detection mechanism 7 extends in a direction opposite to the opening direction of the protrusion flatness detection groove 11; the groove flatness detection mechanism 7 includes a detection mechanism body 71 connected to the middle position of the detection device body 1, a detection mechanism telescopic component 72 movably inserted in the detection mechanism body 71, a telescopic limit rack 73 provided on the detection mechanism telescopic component 72 and arranged along the length direction of the detection mechanism telescopic component 72, and a telescopic locking component 74 provided on the detection mechanism body 71 and used for plugging and cooperating with the telescopic limit rack 73.

[0057] When detecting the flatness of a groove, the present application inserts the groove flatness detection mechanism 7 into the groove to be detected, and adjusts the detection device body 1 to a horizontal state through the bubble level 10 to ensure that the detection reference is consistent; after releasing the telescopic locking mechanism 9, the elastic pressing mechanism 8 releases the elastic force, and respectively pushes the first telescopic detection mechanism 2 and the second telescopic detection mechanism 3 to move in directions away from each other, and realizes the symmetrical and synchronous extension of the first telescopic detection mechanism 2 and the second telescopic detection mechanism 3 on both sides through the synchronous gear mechanism 4 located in the middle of the detection device body 1, ensuring structural balance and symmetrical detection position; with the synchronous movement of the first telescopic detection mechanism 2 and the second telescopic detection mechanism 3, the first detection limit mechanism 5 and the second detection limit mechanism 6 also move synchronously. When the first detection limit When the first detection limit mechanism 5 and the second detection limit mechanism 6 contact the wall, the groove depth is too large and the flatness is unqualified. When the first detection limit mechanism 5 and the second detection limit mechanism 6 move to the preset position and do not contact the wall, the groove depth is too small and the flatness is qualified. When detecting the flatness of the protrusion, the protruding part of the wall is inserted into the protrusion flatness detection groove 11. When the first detection limit mechanism 5 and the second detection limit mechanism 6 contact the wall, the flatness is qualified. When the first detection limit mechanism 5 and the second detection limit mechanism 6 maintain a gap with the wall, the flatness of the wall protrusion is unqualified. The present application realizes the rapid and efficient detection of the concave and convex areas of the wall surface of the film tank support bottom plate, effectively improves the detection accuracy, reduces the difficulty of operation, and adapts to the rapid determination of the flatness of complex structures.

[0058] like Figure 3 and Figure 6 As shown, the present application can push the telescopic component 72 of the detection mechanism to extend outward and insert it into the groove of the wall to be tested according to actual detection needs. By adjusting the cooperation between the telescopic limit rack 73 and the telescopic locking component 74, the graded positioning and reliable locking of the extended length of the probe can be achieved, thereby avoiding the retraction or displacement of the probe due to force or vibration during the detection process, and ensuring the consistency and repeatability of the detection position each time. The present application discloses adjustability and mechanical locking functions, which can flexibly adapt to wall grooves of different widths or depths, thereby improving the adaptability of the detection device to complex working conditions, while ensuring the accuracy of the detection results and the convenience of on-site operation.

[0059] Further, if Figure 2 and Figure 3 As shown, the elastic pressing mechanism 8 includes a first pushing component 81 located on one side of the synchronous gear mechanism 4 and used to press the first telescopic detection mechanism 2 to move in a direction away from the second telescopic detection mechanism 3, and a second pushing component 82 located on the other side of the synchronous gear mechanism 4 and used to press the second telescopic detection mechanism 3 to move in a direction away from the first telescopic detection mechanism 2;

[0060] The first pushing assembly 81 and the second pushing assembly 82 both include a pressing guide component 811 inserted into the detection device body 1, and an elastic pressing component 812 inserted into the pressing guide component 811. The pressing guide component 811 is provided with a telescopic guide groove 813, and the elastic pressing component 812 is inserted into the telescopic guide groove 813.

[0061] The telescopic guide groove 813 of the present application is used to limit the movement path of the elastic top pressure piece 812, ensuring that the elastic top pressure piece 812 stably releases the driving force in the axial direction. When the telescopic locking mechanism 9 is in the released state, the two elastic top pressure pieces 812 respectively push the first telescopic detection mechanism 2 and the second telescopic detection mechanism 3 to extend synchronously along the opening direction of the corresponding telescopic guide groove 813 after compression release, and ensure the consistency of movement on both sides through the meshing action with the synchronous gear mechanism 4; the present application provides driving force through elastic release, and cooperates with the guide structure to ensure the accuracy of the movement trajectory. It not only has a fast response and a compact structure, but also can be automatically unfolded without external drive, effectively improving the convenience of the telescopic operation of the detection device in actual application and the consistency of the detection benchmarks on both sides, thereby enhancing the adaptability and accuracy of the overall device in the flatness detection of concave and convex structures.

[0062] The elastic pressing member 812 is preferably a spring.

[0063] Furthermore, if Figure 2 and Figure 3 As shown, the first telescopic detection mechanism 2 and the second telescopic detection mechanism 3 each include a telescopic rack assembly 21 movably inserted into the telescopic guide groove 813 and meshing with the synchronous gear mechanism 4, a guide connecting protrusion 22 connected to the telescopic rack assembly 21, a telescopic detection assembly 23 movably inserted into the telescopic guide groove 813 and connected to the guide connecting protrusion 22, a detection extension assembly 24 movably inserted into the telescopic detection assembly 23 along the length direction of the telescopic detection assembly 23, and a telescopic limit assembly 25 inserted into the telescopic detection assembly 23 and the detection extension assembly 24;

[0064] The telescopic detection assembly 23 is inserted into the telescopic guide groove 813 , and the elastic pressing member 812 is located between the telescopic detection assembly 23 and the pressing guide member 811 .

[0065] The telescopic detection assembly 23 of the present application can extend outward along the telescopic guide groove 813 under the push of the elastic top pressure piece 812, driving the first telescopic detection mechanism 2 and the second telescopic detection mechanism 3 to expand symmetrically and synchronously. The end of the telescopic rack assembly 21 is connected to the guide connecting protrusion 22 to ensure force transmission and positioning accuracy during the movement of the structure. The detection extension assembly 24 is used to adjust the length of the detection end to adapt to different wall detection depth and width requirements. The telescopic detection assembly 23 and the detection extension assembly 24 are limited by the telescopic limit assembly 25 to limit the maximum extension distance to prevent over-travel displacement or structural interference. During the entire movement process of the present application, the elastic top pressure piece 812 is located between the top pressure guide component 811 and the telescopic detection assembly 23. When the elastic force is released, the telescopic detection assembly 23 is pushed to move smoothly outward, forming a synchronous expansion of the detection end, and adaptive length adjustment is performed through the detection extension assembly 24; the present application realizes adaptive extension, precise positioning and structural symmetrical synchronization of the detection end through a multi-stage sliding fit and meshing limit design, thereby improving the adaptability of the device to different wall concave and convex structures, effectively reducing the complexity of the detection operation and ensuring the judgment accuracy.

[0066] The telescopic limiting component 25 is preferably a bolt.

[0067] Specifically, if Figure 2 As shown, a convex guide slot 814 is provided on the top-pressing guide component 811 , and the guide connection convex edge 22 is movably inserted into the convex guide slot 814 .

[0068] The guide connection protrusion 22 of the present application is movably inserted into the protrusion guide groove 814. When the elastic top pressure piece 812 releases the driving force to push the telescopic detection component 23 and the guide connection protrusion 22 to move, the protrusion guide groove 814 provides a precise motion trajectory restriction for the guide connection protrusion 22, ensuring that the guide connection protrusion 22 slides smoothly along the predetermined straight line direction, effectively preventing lateral deviation, shaking or jamming, and at the same time improving the coordination consistency of the first telescopic detection mechanism 2 and the second telescopic detection mechanism 3 under the linkage of the synchronous gear mechanism 4. The present application not only ensures the movement stability of the elastic push and detection end structure, but also improves the positioning accuracy and operational reliability of the overall detection device.

[0069] More specifically, if Figure 3 As shown, the synchronous gear mechanism 4 includes a rotating bearing 41 sleeved on the periphery of the groove flatness detection mechanism 7, and a rotating gear 42 sleeved on the periphery of the rotating bearing 41 and connected to the rotating bearing 41;

[0070] The telescopic rack assembly 21 includes a telescopic rack body 211 and a telescopic transmission rack 212 provided on one side of the telescopic rack body 211 and meshing with the rotating gear 42 . The end of the telescopic rack body 211 is connected to the end of the guide connection protrusion 22 .

[0071] The rotating bearing 41 of the present application is used to support the rotating gear 42 to rotate smoothly around the central axis. The rotating gear 42 is engaged with the telescopic transmission racks 212 on the left and right sides. The telescopic transmission rack 212 is arranged on one side of the telescopic rack body 211, and the end of the telescopic rack body 211 is connected to the end of the guide connecting protrusion 22, thereby forming a complete drive transmission chain; when the elastic top pressure piece 812 pushes the telescopic detection assembly 23 on either side to move, the driving force of the elastic top pressure piece 812 is transmitted to the telescopic rack body 211 through the guide connecting protrusion 22, thereby driving the telescopic transmission rack 212 to move in the telescopic direction, and the rotating gear 42 is synchronously driven to rotate, and the rotating gear 42 drives the telescopic rack assembly 21 on the other side to achieve synchronous reverse movement; the present application realizes the symmetrical and synchronous deployment of the telescopic detection mechanisms on both sides through the gear rack linkage method, which not only improves the coordination and structural symmetry of the detection action, but also avoids the offset error caused by unilateral push, thereby effectively improving the consistency of the limit reference and the accuracy of the detection results during the wall flatness detection process.

[0072] In addition, if Figure 3 and Figure 4 As shown, the telescopic rack assembly 21 further includes a telescopic locking rack 213 provided on the other side of the telescopic rack body 211 and symmetrically arranged with the telescopic transmission rack 212; a locking through hole 12 is provided on the detection device body 1;

[0073] The telescopic locking mechanism 9 includes a toggle flip shaft 91 inserted in the locking through hole 12 and connected to the detection device body 1, a toggle flip assembly 92 hinged to the toggle flip shaft 91, a toggle protrusion 93 connected to the toggle flip assembly 92 and located on one side of the toggle flip assembly 92, a plug-in limit protrusion 94 connected to the other side of the toggle flip assembly 92, and an elastic pressing assembly 95 connected to the detection device body 1 and located between the detection device body 1 and the toggle protrusion 93; the elastic pressing assembly 95 is used to press the toggle protrusion 93 so that the plug-in limit protrusion 94 is inserted into the locking through hole 12 with the toggle flip shaft 91 as the rotation axis, and is plugged into and matched with the telescopic locking rack 213.

[0074] The elastic pressing component 95 of the present application provides elastic force to press the toggle cam 93, so that the toggle flip component 92 rotates around the toggle flip axis 91, so that the plug-in limit cam 94 is inserted into the locking through hole 12, and plugged into the telescopic locking rack 213 to form a mechanical lock, preventing the first telescopic detection mechanism 2 and the second telescopic detection mechanism 3 from accidentally moving before detection or during transportation. When the first telescopic detection mechanism 2 and the second telescopic detection mechanism 3 need to be released, it is only necessary to press the toggle cam 93 to overcome the elastic force of the elastic pressing component 95, drive the toggle flip component 92 to rotate around the toggle flip axis 91, and realize the separation of the plug-in limit cam 94 and the telescopic locking rack 213, thereby releasing the locked state. The present application realizes rapid locking and unlocking through mechanical linkage, ensuring that the detection device can maintain structural stability and easy operation during the standby or detection stage, thereby improving detection safety and reliability.

[0075] The elastic pressing component 95 is preferably a spring.

[0076] And, as Figure 5 and Figure 6 As shown, the first detection limit mechanism 5 and the second detection limit mechanism 6 both include a limit mechanism body 51 connected to the end of the detection extension component 24, a limit mechanism extension component 52 movably inserted in the limit mechanism body 51, a movable limit rack 53 provided on the limit mechanism extension component 52 and arranged along the length direction of the limit mechanism extension component 52, and an extension limit component 54 provided on the limit mechanism body 51 and used for movably plugging with the movable limit rack 53.

[0077] The detection extension component 24 of the present application is used to drive the limit mechanism body 51 to move outward to detect the flatness of the wall; the limit mechanism extension component 52 is used to extend outward to adapt to different detection needs. When it is necessary to detect the flatness of different wall protrusions, the limit mechanism extension component 52 is unlocked by extending the limit component 54, and the length of the extended limit component 54 in the vertical direction relative to the detection extension component 24 is adjusted. Multi-level positioning and stable limiting are achieved by mechanically plugging the moving limit rack 53 and the extended limit component 54 to prevent the limit end from retracting during detection operation or external force impact, thereby ensuring the repeatability and accuracy of each measurement. The present application improves the adaptability of the wall flatness detection device to walls of different widths and structures through modular, adjustable detection ends and multi-level plug-in limit designs, thereby enhancing the reliability of the detection results and the convenience of operation.

[0078] Furthermore, if Figure 2 and 6 As shown, the present application further discloses that the limiting mechanism body 51 is provided with a limiting through hole 511 aligned with the movable limiting rack 53 , and a locking sliding groove 512 provided along the width direction of the limiting mechanism body 51 and communicating with the limiting through hole 511 ;

[0079] The extended limit assembly 54 includes a locking toggle 541 movably inserted in the locking sliding groove 512, a magnetic limit member 542 connected to the locking toggle 541 and used to be aligned with the limit through hole 511, a magnetic unlocking member 543, and a magnetic connector 544 inserted in the limit through hole 511 and used to be plugged into and cooperate with the movable limit rack 53; the magnetic limit member 542 and the magnetic connector 544 magnetically repel each other, and the magnetic unlocking member 543 and the magnetic connector 544 magnetically attract each other.

[0080] When the locking toggle 541 of the present application is used to move along the length direction of the locking sliding groove 512, and when the magnetic limit member 542 is opposite to the magnetic plug-in member 544, due to the repulsion of the magnetic poles of the two, the magnetic plug-in member 544 is pushed into the tooth groove of the movable limit rack 53 to achieve reliable mechanical locking, thereby preventing the extended limit assembly 54 from accidentally retracting or dislocating during the detection process. When adjustment or release is required, the locking toggle 541 is moved to align the magnetic unlocking member 543 with the magnetic plug-in member 544, and the magnetic unlocking member 543 and the magnetic plug-in member 544 are attracted to each other, and the magnetic plug-in member 544 is sucked away from the movable limit rack 53, thereby achieving quick unlocking and position adjustment. The magnetically controlled locking structure of the present application is combined with the mechanical plug-in position, which has both reliable locking and the convenience of one-handed operation, avoiding the wear and failure problems of traditional springs or mechanical buckles, and further improving the flexibility, durability and on-site operation efficiency of the detection end limit adjustment, ensuring that the positioning of each detection is consistent and the measurement process is stable and reliable.

[0081] The telescopic component 72 of the detection mechanism, the telescopic detection component 23 and the limit mechanism extension component 52 of the present application are all provided with scale lines.

[0082] Specifically, if Figure 7 and Figure 8 As shown, the detection mechanism body 71 is provided with a locking sliding through hole 75 aligned with the telescopic limit rack 73; the telescopic locking assembly 74 includes an annular locking slide rail 741 sleeved on the outer wall of the detection mechanism body 71, a rotating sliding component 742 sleeved on the annular locking slide rail 741 and rotatably connected to the annular locking slide rail 741, a locking magnetic component 743 connected to the rotating sliding component 742 and used to align with the locking sliding through hole 75, an unlocking magnetic component 744, and a magnetic plug-in component 745 movably inserted in the locking sliding through hole 75 and used to plug and cooperate with the telescopic limit rack 73; the locking magnetic component 743 and the magnetic plug-in component 745 have magnetic poles that repel each other, and the unlocking magnetic component 744 and the magnetic plug-in component 745 have magnetic poles that attract each other.

[0083] When the present application is in the locked state, the rotating sliding component 742 is rotated to align the locking magnetic component 743 with the magnetic plug-in component 745, and the magnetic poles repel each other, so that the magnetic plug-in component 745 is inserted into the tooth groove of the telescopic limit rack 73 to achieve mechanical locking, thereby preventing the telescopic component 72 of the detection mechanism from accidentally retracting or shifting; when adjustment or unlocking is required, the rotating sliding component 742 is rotated to align the unlocking magnetic component 744 with the magnetic plug-in component 745, and the magnetic poles attract each other, and the magnetic plug-in component 745 is sucked out of the tooth groove, releasing the locked state, and achieving length adjustment or component reset. The present application can achieve fast, low-wear, and highly reliable positioning locking and unlocking through the combination of rotational control and magnetic action, thereby improving the flexibility, reliability and ease of operation of the detection mechanism in the process of detecting different groove depths, and effectively ensuring the consistency and accuracy of measurement.

[0084] More specifically, if Figure 9 As shown, a wall surface flatness detection method includes a wall surface flatness detection device and the following steps:

[0085] S1: When testing the flatness of a wall groove, insert the groove flatness testing mechanism 7 into the wall groove and adjust the testing device body 1 to a horizontal state using the bubble level 10;

[0086] S2: Press the telescopic locking mechanism 9 to release the locking state of the first telescopic detection mechanism 2 and the second telescopic detection mechanism 3;

[0087] S3: The elastic pressing mechanism 8 pushes the first telescopic detection mechanism 2 and the second telescopic detection mechanism 3 to move away from each other;

[0088] S4: When the first detection limit mechanism 5 and the second detection limit mechanism 6 move to the preset positions, the flatness of the wall groove is qualified;

[0089] When the first detection limit mechanism 5 and the second detection limit mechanism 6 are in contact with the wall surface, the flatness of the wall surface groove is unqualified;

[0090] S5: When detecting the flatness of the wall surface protrusion, press the telescopic locking mechanism 9 to release the locking state of the first telescopic detection mechanism 2 and the second telescopic detection mechanism 3;

[0091] S6: The elastic pressing mechanism 8 pushes the first telescopic detection mechanism 2 and the second telescopic detection mechanism 3 to move away from each other, so that the first detection limit mechanism 5 and the second detection limit mechanism 6 move to the preset detection positions;

[0092] S7: Insert the raised portion of the wall into the raised flatness detection groove 11 so that the raised portion of the wall contacts the detection device body 1, and adjust the detection device body 1 to a horizontal state using the bubble level 10;

[0093] S8: When the first detection limit mechanism 5 and the second detection limit mechanism 6 are in contact with the wall surface, the flatness of the wall surface protrusion is qualified; when the first detection limit mechanism 5 and the second detection limit mechanism 6 maintain a gap with the wall surface, the flatness of the wall surface protrusion is unqualified.

[0094] When detecting the flatness of the wall groove, the present application first inserts the groove flatness detection mechanism 7 into the wall groove to be tested, adjusts the detection device body 1 to a horizontal position through the bubble level 10, and then presses the telescopic locking mechanism 9 to release the locking state of the first telescopic detection mechanism 2 and the second telescopic detection mechanism 3. The elastic pressing mechanism 8 releases the elastic force and pushes the telescopic detection mechanisms on both sides to expand synchronously in opposite directions, driving the first detection limit mechanism 5 and the second detection limit mechanism 6 to move. If the first telescopic detection mechanism 2 and the second telescopic detection mechanism 3 can move to the preset position and do not contact the wall surface, it is determined that the groove flatness is qualified. If contact occurs, It is unqualified; when detecting the flatness of the protrusion, first unlock the first telescopic detection mechanism 2 and the second telescopic detection mechanism 3 on both sides and drive them to unfold by the elastic top pressure mechanism 8, insert the protrusion of the wall into the protrusion flatness detection groove 11, and use the bubble level 10 to adjust the horizontal state. If the first detection limit mechanism 5 and the second detection limit mechanism 6 are in contact with the wall surface measured around the protrusion, the flatness is judged to be qualified. If there is a gap, it is unqualified. The present application ensures the detection benchmark through the bubble level 10, and realizes efficient and accurate detection of concave and convex areas through mechanical linkage and limit contact. The present application has strong adaptability, clear judgment standards, and simple operation procedures.

[0095] The implementation principle of a wall flatness detection device and detection method in the embodiment of the present application is as follows:

[0096] A wall surface flatness detection device, when detecting the flatness of a groove, the groove flatness detection mechanism 7 is inserted into the groove to be detected, and the detection device body 1 is adjusted to a horizontal state by a bubble level 10 to ensure that the detection reference is consistent; after the telescopic locking mechanism 9 is released, the elastic pressing mechanism 8 releases the elastic force, respectively pushing the first telescopic detection mechanism 2 and the second telescopic detection mechanism 3 to move in directions away from each other, and the symmetrical and synchronous extension of the first telescopic detection mechanism 2 and the second telescopic detection mechanism 3 on both sides is achieved through the synchronous gear mechanism 4 located in the middle of the detection device body 1, ensuring structural balance and symmetrical detection position; with the synchronous movement of the first telescopic detection mechanism 2 and the second telescopic detection mechanism 3, the first detection limit mechanism 5 and the second detection limit mechanism 6 also move synchronously, when When the first detection limit mechanism 5 and the second detection limit mechanism 6 contact the wall surface, the groove depth is too large and the flatness is unqualified. When the first detection limit mechanism 5 and the second detection limit mechanism 6 move to the preset position and do not contact the wall surface, the groove depth is too small and the flatness is qualified. When detecting the flatness of the protrusion, the protruding part of the wall surface is inserted into the protrusion flatness detection groove 11. When the first detection limit mechanism 5 and the second detection limit mechanism 6 contact the wall surface, the flatness is qualified. When the first detection limit mechanism 5 and the second detection limit mechanism 6 maintain a gap with the wall surface, the flatness of the wall surface protrusion is unqualified. The present application realizes rapid and efficient detection of concave and convex areas on the wall surface of the supporting bottom plate of the film tank, effectively improves detection accuracy, reduces operation difficulty, and is suitable for rapid flatness determination of complex structures.

[0097] When the locking cam 720 is in the locked state, the locking cam 720 is in the locked state, and the locking cam 720 is in the locked state, so that the locking cam 720 is locked and the locking cam 720 is locked.

[0098] A method for detecting the flatness of a wall surface. When detecting the flatness of a wall surface groove, first insert the groove flatness detection mechanism 7 into the groove of the wall surface to be detected, adjust the detection device body 1 to a horizontal level by using a bubble level 10, then press the telescopic locking mechanism 9 to release the locking state of the first telescopic detection mechanism 2 and the second telescopic detection mechanism 3, and the elastic pressing mechanism 8 releases the elastic force to push the telescopic detection mechanisms on both sides to expand synchronously in opposite directions, driving the first detection limit mechanism 5 and the second detection limit mechanism 6 to move. If the first telescopic detection mechanism 2 and the second telescopic detection mechanism 3 can move to the preset position and do not touch the wall surface, it is determined that the groove flatness is qualified. If not, If there is any contact with the wall around the raised part, it is judged to be unqualified; when testing the flatness of the protrusion, first unlock the first telescopic detection mechanism 2 and the second telescopic detection mechanism 3 on both sides and drive them to unfold by the elastic top pressure mechanism 8, insert the raised part of the wall into the protrusion flatness detection groove 11, and use the bubble level 10 to adjust the horizontal state. If the first detection limit mechanism 5 and the second detection limit mechanism 6 are in contact with the wall around the raised part, the flatness is judged to be qualified. If there is a gap, it is unqualified. The present application ensures the detection benchmark through the bubble level 10, and realizes efficient and accurate detection of concave and convex areas through mechanical linkage and limit contact. The present application has strong adaptability, clear judgment standards and simple operation procedures.

[0099] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
