Description

Technical Field

[0001] The present invention relates to the technical field of steel structure monitoring, and in particular to a distributed steel structure deformation monitoring system and method. Background Art

[0002] Steel structure prefabricated buildings are a new type of standardized and modular building system with steel structure as the structural system, and factory production of parts and components, prefabricated construction, integrated decoration, and information management as the main features. They have the advantages of fast and efficient, less on-site operations, and good seismic performance. They are easy to realize the modernization and industrialization of the construction industry. In recent years, many accidents such as collapse and fire of steel structure buildings have occurred both internationally and domestically. Therefore, in the process of vigorously developing and promoting steel structure prefabricated buildings, it is very important to develop and apply safety monitoring technology for steel structure prefabricated buildings.

[0003] Although there are relevant national and industry standards for the design, processing, and installation of steel structure prefabricated buildings, an important part of on-site monitoring of steel structure component factories, bridges, or other steel structure components is deformation monitoring of steel structure components. Deformation monitoring is mainly applicable to internal flaw detection and external deformation monitoring of steel structures or components. External deformation can generally be directly judged by human eye observation, but internal structural flaw detection requires professional equipment. The existing flaw detection method is to monitor through manual handheld flaw detection instruments, but this method is for monitoring steel structures that have not been installed. For assembled steel structures, staff generally climb to a high place and use handheld flaw detection equipment for local flaw detection monitoring. This method is not only inefficient in flaw detection monitoring, but also has serious safety hazards. There are also some monitoring equipment in modern society, but they can only be used for flaw detection monitoring on some steel structure planes. For some complex structural surfaces (for example: Fig. 9 and Fig.10 ), it cannot pass smoothly and its scope of use is limited. Therefore, in view of the above problems, a distributed steel structure deformation monitoring system and method are proposed. Summary of the invention

[0004] The object of the present invention is to provide a distributed steel structure deformation monitoring system and method to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] As an optional solution of the distributed steel structure deformation monitoring system and method described in the present invention, wherein: a distributed steel structure deformation monitoring system and method comprises a support plate and a protective shell;

[0007] The surface of the bracket plate is installed with a protective shell and a pre-processing module, and the pre-processing module passes through the upper and lower end surfaces of the bracket plate. The inner side of each group of the protective shells is provided with two groups of walking modules rotatably connected to the bracket plate and a group of wheel adjustment modules for adjusting the angle of the walking modules;

[0008] The opposite end surfaces of the two groups of bracket plates are fixedly connected with flexible connecting beams, and the flexible connecting beams are internally installed with flaw detection modules for detecting steel structures that penetrate through the flexible connecting beams;

[0009] The bottom of the bracket plate is fixedly connected with a driven wheel which plays a guiding role.

[0010] The existing flaw detection method is to monitor by hand-held flaw detection instruments, but this method is for monitoring steel structures that have not been installed. For assembled steel structures, workers usually climb to a high place and use hand-held flaw detection equipment to perform local flaw detection monitoring. This method not only has low flaw detection monitoring efficiency, but also has serious safety hazards. There are also some monitoring equipment in modern society, but they can only perform flaw detection monitoring on some steel structure planes. For some complex structure surfaces, it cannot pass smoothly, and its scope of use is limited. When the present invention is used, two sets of bracket plates distributed front and back are provided, and The support plates are connected by flexible connecting beams, and a flaw detection module for flaw detection is installed in the center of the flexible connecting beam. When walking, the distributed walking modules drive the support plates, flexible connecting beams and flaw detection modules to move. When passing through some complex steel structure surfaces, the flexible connecting beams are used as traction to prevent the front walking module from detaching from the steel structure and falling off, thereby ensuring good adaptability to different complex road conditions. This setting does not require manual handheld equipment and climbing to high places to monitor steel structure deformation and flaw detection, which not only ensures work efficiency but also avoids the safety hazards caused by manual climbing to high places.

[0012] A shovel plate is fixedly connected to one side of the interior of the installation shell, and the interior of the shovel plate is slidably connected to the cleaning block.

[0013] As an optional solution of the distributed steel structure deformation monitoring system and method described in the present invention, discharge troughs are provided on both sides of the installation shell, and a mesh is also installed on the surface of the installation shell.

[0014] As an optional solution of the distributed steel structure deformation monitoring system and method described in the present invention, a top plate is fixedly connected to the inner side of the installation shell, and the bottom of the top plate is arranged in contact with the connecting rod.

[0015] As an optional solution of the distributed steel structure deformation monitoring system and method described in the present invention, a mounting plate is fixedly connected to the outer side of the first motor, and the other end of the mounting plate is fixedly connected to the mounting shell.

[0016] As an optional solution of the distributed steel structure deformation monitoring system and method described in the present invention, one side of the shovel plate is inclined, and a concave material trough is opened inside the shovel plate.

[0017] When performing mobile monitoring, the first motor inside the mounting shell drives the rotating shaft to rotate, and the rotating shaft drives the rotating cylinder and the cleaning brush to rotate. At this time, the surface of the steel structure that has passed through can be cleaned to ensure the monitoring quality of the flaw detection module;

[0018] In order to prevent the cleaned dust and impurities from falling back onto the surface of the steel structure to be monitored, the active gear on the outside of the rotating shaft drives the driven gear to rotate, and the driven gear can drive the internal reciprocating screw to rotate, and the sliding sleeve is driven by the slider to move back and forth, and the connecting rod is driven to move, so that the cleaning block at one end of the connecting rod slides back and forth in the internal material groove of the shovel plate. At this time, the impurities cleaned by the cleaning brush can enter the material groove through the inclined surface of the shovel plate. The reciprocating movement of the cleaning block can push the impurities and dust out of the material groove of the shovel plate and discharge them through the discharge trough, thereby ensuring the quality of subsequent monitoring;

[0019] At the same time, when the connecting rod moves back and forth, the top plate provided thereon serves the purpose of squeezing the connecting rod to prevent it from rotating with the sliding sleeve, and the provided mesh can ensure that when the lower surface of the steel structure is cleaned, dust falls smoothly through the mesh.

[0020] As an optional solution of the distributed steel structure deformation monitoring system and method described in the present invention, the wheel adjustment module includes a protective cover, a double-axle motor and a threaded rod, the bottom of the protective cover is fixedly connected to the bracket plate, the inside of the protective cover is fixedly connected to the double-axle motor, and the two main shaft ends of the double-axle motor are fixedly connected to the threaded rod, the outer side of the threaded rod is spirally connected to the threaded barrel, and the outer side of the threaded barrel is fixedly connected to the guide column arranged symmetrically;

[0021] Connecting covers are arranged on both sides of the interior of the protective cover, and the other end of the connecting cover is fixedly connected to the walking module. Guide grooves are arranged on both sides of the inner wall of the connecting cover, and the connecting cover is slidably connected to the guide column through the guide grooves.

[0022] As an optional solution of the distributed steel structure deformation monitoring system and method described in the present invention, the guide groove is arranged at an angle.

[0023] When monitoring columnar steel structure components, the outer magnetic wheel cannot stably fit tightly with the curved steel structure. At this time, the double-axis motor is started to drive the threaded rods on both sides to rotate, the threaded rods drive the threaded cylinders to move, and the threaded cylinders drive the guide columns on both sides to move. At this time, under the action of the inclined guide groove, the connecting cover can drive the frequency modulation motor and the rotating plate to rotate slightly with the rotating rod as the center, ensuring that the outer magnetic wheel is at a certain inclination angle and in contact with the curved steel structure to ensure its stable movement.

[0024] As an optional solution of a distributed steel structure deformation monitoring system and method described in the present invention, wherein: the flaw detection module includes a protective shell, a second motor and a threaded shaft, the outer side of the protective shell is fixedly connected to the flexible connecting beam, the inside of the protective shell is fixedly connected to the second motor, and the end of the main shaft of the second motor is fixedly connected to the threaded shaft, and the other end of the threaded shaft is rotatably connected to the protective shell, the outer side of the threaded shaft is spirally connected to a moving block, the outer side of the moving block is fixedly connected to a support seat, and the other end of the support seat is fixedly connected to a flaw detection device;

[0025] A bottom cover is fixedly connected to one side of the protective shell, a strip-shaped limiting groove is provided in the center of the bottom cover, and a flaw detection device is arranged inside the limiting groove, and electromagnets fixedly connected to the bottom cover are arranged on both sides of the limiting groove;

[0026] Both sides of the bottom cover are provided with arc surfaces.

[0027] As an optional solution of the distributed steel structure deformation monitoring system and method described in the present invention, limit columns fixedly connected to the protective shell are arranged on both sides of the threaded shaft, and the outer sides of the limit columns are slidably connected to the moving block.

[0028] When the flaw detection equipment is monitoring the steel structure, it can drive the threaded shaft to move through the second motor, the threaded shaft drives the moving block to move, the moving block drives the support seat to move, and the support seat drives the flaw detection equipment to slide inside the limit groove. At this time, the surface of the steel structure can be monitored in the longitudinal direction to expand the monitoring area and ensure data accuracy. The electromagnets set can ensure that the bottom cover fits the steel structure to ensure the monitoring quality. At the same time, when passing through some complex steel structure surfaces, the curved surface serves a guiding purpose to ensure the passability of the equipment.

[0029] As an optional scheme of a distributed steel structure deformation monitoring system and method described in the present invention, the walking module includes a driving frequency-modulated motor, a rotating plate and a rotating rod, the bottom of the driving frequency-modulated motor is fixedly connected to the rotating plate, both sides of the rotating plate are fixedly connected to the rotating rod, and the other end of the rotating rod is rotatably connected to the bracket plate, the free end of the driving frequency-modulated motor is fixedly connected to the inner guide wheel, and the outer side of the inner guide wheel is fixedly connected to the outer magnetic wheel.

[0030] When monitoring steel structures, it drives the frequency-modulated motor to drive the inner guide wheel and the outer magnetic wheel to rotate. The outer magnetic wheel is adsorbed on the surface of the steel structure, which can ensure stable movement. For inclined steel structure components, it can move on the lower surface of the steel structure for monitoring, expanding the monitoring range.

[0031] As an optional solution of the distributed steel structure deformation monitoring system and method described in the present invention, the method of use is as follows:

[0032] Step 1: Debug the equipment before use to ensure that each module is operating normally before putting it into use;

[0033] Step 2: When monitoring steel structure components, place the walking module on the surface of the steel structure, and then start the walking module to drive the equipment to move. The front and rear sets of walking modules ensure that they can move according to different road conditions;

[0034] Step 3: When testing the steel structure of the column, the angles of the walking modules on both sides can be adjusted through the wheel adjustment module to facilitate contact with the curved surface of the column for climbing and moving;

[0035] Step 4: When the device is climbing and moving, the flaw detection module provided therein can be attached to the surface of the steel structure, and the flaw detection monitoring equipment can be used for monitoring. During the monitoring process, the flaw detection monitoring equipment can be moved longitudinally to expand the flaw detection monitoring range.

[0036] Step 5: During the actual movement process, the pre-processing module can pre-process the pre-passed road surface to ensure the monitoring quality of the subsequent flaw detection module.

[0037] Compared with the prior art, the present invention has the following beneficial effects:

[0038] When the present invention is in use, two groups of bracket plates distributed front and back are provided, and the bracket plates are connected by a flexible connecting beam, and a flaw detection module for flaw detection is installed in the center of the flexible connecting beam. When walking, the distributed walking module drives the bracket plate, the flexible connecting beam and the flaw detection module to move. When passing through some complex steel structure surfaces, the flexible connecting beam is used as a traction to prevent the front walking module from being separated from the steel structure and falling off, which can ensure good adaptability to different complex road conditions. This setting does not require manual hand-held equipment and climbing high to monitor steel structure deformation and flaw detection, which not only ensures work efficiency but also avoids safety hazards caused by manual climbing high.

[0039] When monitoring steel structures, it drives the frequency modulation motor to drive the inner guide wheel and the outer magnetic wheel to rotate. The outer magnetic wheel is adsorbed on the surface of the steel structure, which can ensure stable movement. In addition, for inclined steel structure components, it can move under the steel structure for monitoring, expanding the monitoring range.

[0040] When monitoring a columnar steel structure, its outer magnetic wheel cannot stably fit tightly with the curved steel structure. At this time, the double-shaft motor is started to drive the threaded rods on both sides to rotate, the threaded rods drive the threaded barrel to move, and the threaded barrel drives the guide columns on both sides to move. At this time, under the action of the inclined guide groove, the connecting cover can drive the frequency modulation motor and the rotating plate to rotate slightly with the rotating rod as the center, ensuring that the outer magnetic wheel is at a certain tilt angle and in contact with the curved steel structure to ensure its stable walking;

[0041] When performing mobile monitoring, the first motor inside the mounting shell drives the rotating shaft to rotate, and the rotating shaft drives the rotating cylinder and the cleaning brush to rotate. At this time, the surface of the steel structure that has passed through can be cleaned to ensure the monitoring quality of the flaw detection module;

[0042] In order to prevent the cleaned dust and impurities from falling back onto the surface of the steel structure to be monitored, the active gear on the outside of the rotating shaft drives the driven gear to rotate, and the driven gear can drive the internal reciprocating screw to rotate, and the sliding sleeve is driven by the slider to move back and forth, and the connecting rod is driven to move, so that the cleaning block at one end of the connecting rod slides back and forth in the internal material groove of the shovel plate. At this time, the impurities cleaned by the cleaning brush can enter the material groove through the inclined surface of the shovel plate. The reciprocating movement of the cleaning block can push the impurities and dust out of the material groove of the shovel plate and discharge them through the discharge trough, thereby ensuring the quality of subsequent monitoring;

[0043] At the same time, when the connecting rod reciprocates, the top plate provided thereon serves to squeeze the connecting rod to prevent it from rotating with the sliding sleeve, and the provided mesh can ensure that dust falls smoothly through the mesh when cleaning the lower surface of the steel structure;

[0044] When the flaw detection equipment is monitoring the steel structure, it can drive the threaded shaft to move through the second motor, the threaded shaft drives the moving block to move, the moving block drives the support seat to move, and the support seat drives the flaw detection equipment to slide inside the limit groove. At this time, the surface of the steel structure can be monitored in the longitudinal direction to expand the monitoring area and ensure data accuracy. The electromagnets set can ensure that the bottom cover fits the steel structure to ensure the monitoring quality. At the same time, when passing through some complex steel structure surfaces, the curved surface serves a guiding purpose to ensure the passability of the equipment.

DETAILED DESCRIPTION

[0056] Example 1: Please refer to Figure 1 , Fig. 9 and Fig.10 , the present invention provides a technical solution:

[0057] A distributed steel structure deformation monitoring system and method, comprising a support plate 1 and a protective shell 2;

[0058] The surface of the bracket plate 1 is installed with a protective shell 2 and a pre-processing module 3, and the pre-processing module 3 passes through the upper and lower end surfaces of the bracket plate 1. The inner side of each group of the protective shells 2 is provided with two groups of walking modules 6 for walking and a group of wheel adjustment modules 7 for adjusting the angle of the walking modules 6, which are rotatably connected to the bracket plate 1.

[0059] The two sets of bracket plates 1 are fixedly connected to opposite end surfaces with flexible connecting beams 4, and the flexible connecting beams 4 are internally installed with flaw detection modules 5 for detecting steel structures penetrating therethrough;

[0060] The bottom of the bracket plate 1 is fixedly connected with a driven wheel 8 which plays a guiding role.

[0061] The above usage is as follows:

[0062] Step 1: Debug the equipment before use to ensure that each module is operating normally before putting it into use;

[0063] Step 2: When monitoring the steel structure components, the walking module 6 is placed on the surface of the steel structure, and then the walking module 6 is started to drive the equipment to move. The front and rear groups of walking modules 6 ensure that they can move according to different road conditions;

[0064] Step 3: When testing the steel structure of the column, the angles of the walking modules 6 on both sides can be adjusted through the wheel adjustment module 7 to facilitate contact with the curved surface of the column for climbing and moving;

[0065] Step 4: When the device is climbing and moving, the flaw detection module 5 provided therein can be attached to the surface of the steel structure, and the flaw detection monitoring equipment can be used for monitoring. During the monitoring process, the flaw detection monitoring equipment can be moved longitudinally to expand the flaw detection monitoring range.

[0066] Step 5: During the actual movement process, the pre-processing module 3 can pre-process the road surface to ensure the monitoring quality of the subsequent flaw detection module 5.

[0067] The existing flaw detection method is to monitor by handheld flaw detection instruments, but this method is for monitoring steel structures that have not been installed. For assembled steel structures, workers usually climb to a high place and use handheld flaw detection equipment to perform local flaw detection monitoring. This method is not only inefficient in flaw detection monitoring, but also has serious safety hazards. There are also some monitoring equipment in modern society, but they can only perform flaw detection monitoring on some steel structure planes. For some complex structural surfaces (for example: Fig. 9 and Fig.10 ), it cannot pass smoothly, and its scope of use is limited. When the present invention is in use, two groups of bracket plates 1 distributed front and back are provided, and the bracket plates 1 are connected by flexible connecting beams 4, and a flaw detection module 5 for flaw detection is installed in the center of the flexible connecting beam 4. When walking, the distributed walking module 6 drives the bracket plate 1, the flexible connecting beam 4 and the flaw detection module 5 to move. When passing through some complex steel structure surfaces, the flexible connecting beam 4 is used as a traction to prevent the front walking module 6 from being separated from the steel structure and falling, which can ensure good adaptability to different complex road conditions. This setting does not require manual handheld equipment and climbing high to monitor steel structure deformation and flaw detection, which not only ensures work efficiency but also avoids the safety hazards caused by manual climbing high;

[0068] In this embodiment, complex road conditions are not limited to Fig. 9 and Fig.10 There are two types of road conditions. You can move according to the actual road conditions. Fig. 9When the road condition is bad, the walking module 6 on the front side passes the raised part in advance, and then under the action of the flexible connecting beam 4, it will not fall directly, but will gradually contact with the other end surface of the raised part to achieve subsequent stable movement, and when the walking module 6 on the rear side passes the raised part, its flexible connecting beam 4 can drive the front side of the walking module 6 downward in advance, and then slowly drive the wheels of the walking module 6 to pass over the raised part. Even if the rear walking module 6 is separated from the steel structure, it can be towed by the walking module 6 on the front side to slowly reset it. It has the advantage of automatically adjusting the state, and the set driven wheel 8 serves the purpose of guidance to ensure the normal walking of the walking module 6.

[0069] Example 2: This example is an improvement on Example 1. Figure 2 , Figure 3 and Figure 4 Specifically, the pre-processing module 3 includes a mounting shell 301, a first motor 302 and a mounting plate 303.

The interior of the mounting shell 301 is fixedly connected to the first motor 302, and the main shaft end of the first motor 302 is fixedly connected to a rotating shaft 304. The outer side of the rotating shaft 304 is fixedly connected to a rotating cylinder 305 and a driving gear 307. The outer side of the rotating cylinder 305 is fixedly connected to a cleaning brush 305 evenly distributed. 06, the outer side of the driving gear 307 is meshed with a driven gear 308, and the inner side of the driven gear 308 is fixedly connected with a reciprocating screw rod 309, both ends of the reciprocating screw rod 309 are rotationally connected with the mounting shell 301, the outer side of the reciprocating screw rod 309 is slidably connected with a slider 310, and the other end of the slider 310 is fixedly connected with a sleeve 311, the outer side of the sleeve 311 is fixedly connected with a connecting rod 312, and the other end of the connecting rod 312 is fixedly connected with a cleaning block 313;

[0070] A shovel plate 315 is fixedly connected to one side of the interior of the installation shell 301 , and the interior of the shovel plate 315 is slidably connected to the cleaning block 313 .

[0071] Discharge slots 314 are provided on both sides of the installation shell 301 , and a mesh sheet 317 is also installed on the surface of the installation shell 301 .

[0072] A top plate 316 is also fixedly connected to the inner side of the installation shell 301 , and the bottom of the top plate 316 is in contact with the connecting rod 312 .

[0073] A mounting plate 303 is fixedly connected to the outer side of the first motor 302 , and the other end of the mounting plate 303 is fixedly connected to the mounting shell 301 .

[0074] One side of the shovel plate 315 is inclined, and a concave material trough is provided inside the shovel plate 315 .

[0075] When performing mobile monitoring, the first motor 302 inside the mounting shell 301 drives the rotating shaft 304 to rotate, and the rotating shaft 304 drives the rotating cylinder 305 and the cleaning brush 306 to rotate. At this time, the surface of the steel structure that has passed through can be cleaned to ensure the monitoring quality of the flaw detection module 5; in order to prevent the cleaned dust and impurities from falling back on the surface of the steel structure to be monitored, the driving gear 307 outside the rotating shaft 304 drives the driven gear 308 to rotate, and the driven gear 308 can drive the internal reciprocating screw 309 to rotate, and the sliding sleeve 310 drives the sliding sleeve 310 to rotate. 1 reciprocates and drives the connecting rod 312 to move, so that the cleaning block 313 at one end of the connecting rod 312 slides back and forth in the internal material groove of the shovel plate 315. At this time, the impurities cleaned by the cleaning brush 306 can enter the material groove through the inclined surface of the shovel plate 315. The reciprocating movement of the cleaning block 313 can push the impurities and dust out of the material groove of the shovel plate 315 and discharge them through the discharge groove 314 to ensure the subsequent monitoring quality; at the same time, when the connecting rod 312 reciprocates, the top plate 316 provided therein serves to squeeze the connecting rod 312 to prevent it from rotating with the sliding sleeve 311;

[0076] In this embodiment, the first motor 302 drives the rotating shaft 304 to rotate, and the rotating shaft 304 drives the rotating cylinder 305 and the cleaning brush 306 on the outside to clean the surface of the steel structure to ensure the quality of subsequent monitoring. At the same time, the driving gear 307 on the outside of the rotating shaft 304 drives the driven gear 308 to rotate, and there is no sliding groove on one side of the reciprocating screw rod 309 on the inner side of the driven gear 308, ensuring that the sliding sleeve 311 reciprocates on one side of the driven gear 308 under the action of the slider 310, thereby ensuring the quality of subsequent impurity cleaning;

[0077] The L-shaped connecting rod 312 drives the cleaning block 313 to slide in the internal material groove of the shovel plate 315, and at this time, the dust and impurities in the material groove of the shovel plate 315 can be pushed out, and one side of the shovel plate 315 is inclined, and at this time, it can cooperate with the cleaning brush 306 to collect the impurities into the material groove, which is convenient for subsequent cleaning;

[0078] In actual use, the top plate 316 is arranged in a rectangular shape, and the bottom is in contact with the surface of the connecting rod 312 in a sliding connection, which serves the purpose of supporting the connecting rod 312 and ensuring that the connecting rod 312 moves stably along the trajectory;

[0079] When the device cleans the lower surface of an inclined steel structure or a horizontal steel structure, the dust is cleaned by the cleaning brush 306 and falls smoothly through the mesh 317 to avoid accumulation inside the installation shell 301.

[0080] Example 3: This example is an improvement on Example 2. Figure 8Specifically, the wheel adjustment module 7 includes a protective cover 701, a double-axle motor 702 and a threaded rod 703. The bottom of the protective cover 701 is fixedly connected to the bracket plate 1. The double-axle motor 702 is fixedly connected inside the protective cover 701, and the two main shaft ends of the double-axle motor 702 are fixedly connected to the threaded rod 703. The outer side of the threaded rod 703 is spirally connected to a threaded cylinder 704, and the outer side of the threaded cylinder 704 is fixedly connected to a symmetrically arranged guide column 705.

[0081] Connecting covers 706 are provided on both sides of the interior of the protective cover 701, and the other end of the connecting cover 706 is fixedly connected to the walking module 6. Guide grooves 707 are provided on both sides of the inner wall of the connecting cover 706, and the connecting cover 706 is slidably connected to the guide column 705 through the guide grooves 707.

[0082] The guide groove 707 is arranged to be inclined.

[0083] When monitoring a columnar steel structure, its outer magnetic wheel 605 cannot stably fit tightly with the curved steel structure. At this time, the double-axis motor 702 is started to drive the threaded rods 703 on both sides to rotate, the threaded rods 703 drive the threaded cylinder 704 to move, and the threaded cylinder 704 drives the guide columns 705 on both sides to move. At this time, under the action of the inclined guide groove 707, the connection cover 706 can drive the frequency modulation motor 601 and the rotating plate 602 to rotate slightly around the rotating rod 603, ensuring that the outer magnetic wheel 605 is at a certain tilt angle and in contact with the curved steel structure to ensure its stable walking.

[0084] In this embodiment, the threads on the outer sides of the threaded rods 703 on both sides of the double-output shaft motor 702 are arranged in opposite directions, so that the rotation of the double-output shaft motor 702 can drive the threaded cylinders 704 on both sides to move synchronously in opposite directions or towards each other, thereby ensuring that the walking modules 6 on both sides are driven to adjust synchronously;

[0085] A certain gap is left between the inner side of the protective cover 701 and the connecting cover 706 to ensure that the connecting cover 706 can rotate to a certain extent, and the guide column 705 cooperates with the guide groove 707, which not only drives the connecting cover 706, but also ensures the stable movement of the threaded tube 705 to avoid its own rotation.

[0086] Example 4: This example is an improvement on Example 3. Figure 5Specifically, the flaw detection module 5 includes a protective shell 501, a second motor 502 and a threaded shaft 503. The outer side of the protective shell 501 is fixedly connected to the flexible connecting beam 4. The second motor 502 is fixedly connected to the inside of the protective shell 501, and the main shaft end of the second motor 502 is fixedly connected to the threaded shaft 503, and the other end of the threaded shaft 503 is rotatably connected to the protective shell 501. The outer side of the threaded shaft 503 is spirally connected to a moving block 504, the outer side of the moving block 504 is fixedly connected to a support seat 505, and the other end of the support seat 505 is fixedly connected to a flaw detection device 506;

[0087] A bottom cover 508 is fixedly connected to one side of the protective shell 501. A strip-shaped limiting groove 509 is provided in the center of the bottom cover 508. A flaw detection device 506 is provided inside the limiting groove 509. Electromagnets 510 fixedly connected to the bottom cover 508 are provided on both sides of the limiting groove 509.

[0088] Both sides of the bottom cover 508 are provided with arc-shaped surfaces 511 .

[0089] Limiting posts 507 fixedly connected to the protective shell 501 are disposed on both sides of the threaded shaft 503 , and the outer sides of the limiting posts 507 are slidably connected to the moving block 504 .

[0090] When the flaw detection device 506 monitors the steel structure, it can drive the threaded shaft 503 to move through the second motor 502, the threaded shaft 503 drives the moving block 504 to move, the moving block 504 drives the support seat 505 to move, and the support seat 505 drives the flaw detection device 506 to slide inside the limit groove 509. At this time, the surface of the steel structure can be monitored in the longitudinal direction, the monitoring area can be expanded, and the data accuracy can be ensured. The electromagnet 510 can ensure that the bottom cover 508 fits the steel structure to ensure the monitoring quality;

[0091] In this embodiment, the electromagnet 510 can be energized according to actual conditions. Figure 5 This is a schematic diagram of the flip structure of the flaw detection module 5. The limit columns 507 set on both sides of the threaded shaft 503 can ensure the stable movement of the moving block 504 and avoid its own rotation. When the device is performing walking monitoring, it can realize movement in a direction perpendicular to the walking path, which can increase the monitored area. At the same time, when passing through some complex steel structure surfaces, its curved surface 511 serves a guiding purpose to ensure the passability of the equipment.

[0092] Example 5: This example is an improvement on Example 4. Figure 6 and Figure 7Specifically, the walking module 6 includes a driving frequency modulation motor 601, a rotating plate 602 and a rotating rod 603. The bottom of the driving frequency modulation motor 601 is fixedly connected to the rotating plate 602, both sides of the rotating plate 602 are fixedly connected to the rotating rod 603, and the other end of the rotating rod 603 is rotatably connected to the bracket plate 1, the free end of the driving frequency modulation motor 601 is fixedly connected to the inner guide wheel 604, and the outer side of the inner guide wheel 604 is fixedly connected to the outer magnetic wheel 605.

[0093] When monitoring the steel structure, the frequency modulation motor 601 is driven to drive the inner guide wheel 604 and the outer magnetic wheel 605 to rotate, and the outer magnetic wheel 605 is adsorbed on the surface of the steel structure, which can ensure stable movement. In addition, for inclined steel structure components, it can move on the lower surface of the steel structure for monitoring, thereby expanding the monitoring range.

[0094] In this embodiment, each driving frequency-modulated motor 601 can freely control its rotation speed to achieve the purpose of steering, and under the action of the wheel adjustment module 7, the driving frequency-modulated motor 601 and the rotating plate 602 are driven to rotate around the rotating rod 603, thereby adjusting the angle of the inner guide wheel 604 and the outer magnetic wheel 605, so that the wheels are in contact with their curved surface. Under the action of the outer magnetic wheel 605, the curved columnar steel structure can be climbed, further expanding the scope of use.
