Description

Technical Field

[0001] This application relates to the field of expansion joint measuring equipment technology, and in particular to a quantitative detection device for changes in expansion joints in water conservancy projects. Background Technology

[0002] Water conservancy projects play a crucial role in controlling and regulating surface water and groundwater, thus possessing significant practical value. In water conservancy projects, expansion joints are often constructed to extend the service life of water conservancy facilities and ensure their normal operation. However, these expansion joints frequently change during use, necessitating regular inspection.

[0003] A search revealed that patent application CN202110662582.X discloses a device for detecting changes in cracks and expansion joints in large-scale hydraulic engineering projects. This device includes a frame, two depth measuring mechanisms, a width measuring mechanism, and a reading mechanism. The two depth measuring mechanisms are symmetrically arranged on both sides of the top of the frame, corresponding to the crack positions on the frame. The width measuring mechanism is mounted on one of the depth measuring mechanisms, and the reading mechanism is mounted on the other. Each depth measuring mechanism includes a mounting assembly and a depth measuring assembly. The mounting assembly is installed on the top of the frame, and the depth measuring assembly is mounted on the mounting assembly, corresponding to the crack positions on the frame. This device can simultaneously detect the width and depth of cracks and expansion joints in hydraulic engineering projects, offering fast measurement speed and low error, thus reducing labor intensity and improving the practicality of the device.

[0004] Regarding the aforementioned technical features, the inventors believe that the following defects exist: First, due to environmental factors, a layer of impurities often adheres to the sidewalls of expansion joints in large-scale water conservancy projects, which can lead to inaccurate measurement of the changes in expansion joints; Second, the above devices only measure the changes in expansion joints but cannot effectively guide subsequent actions, making them relatively simplistic; Third, the operation is cumbersome, affecting the efficiency of detecting changes in expansion joints. Summary of the Invention

[0005] To improve the accuracy of expansion joint measurements and facilitate subsequent repairs of problematic expansion joints, this application provides a quantitative detection device for changes in expansion joints in hydraulic engineering.

[0006] This application provides a quantitative detection device for changes in expansion joints in hydraulic engineering, which adopts the following technical solution:

[0007] A quantitative detection device for changes in expansion joints in hydraulic engineering is disclosed. The device includes a detection frame, moving wheels, a cleaning mechanism, a measuring mechanism, and a marking mechanism. The moving wheels are mounted on the detection frame to facilitate movement of the detection frame along the length of the expansion joint. The detection frame has a starting end and an ending end. The cleaning mechanism is located at the starting end and is used to clean impurities from the inner wall of the expansion joint. The measuring mechanism is located on the detection frame between the starting end and the ending end and is used to detect the width of the expansion joint. The marking mechanism is connected to the measuring mechanism and is used to mark corresponding positions on the expansion joint according to the state of the measuring mechanism.

[0008] By adopting the above technical solution, when quantitatively detecting changes in expansion joints, the detection frame is moved to the expansion joint measurement position. Pushing the detection frame causes the cleaning mechanism to move, and adjusting the cleaning mechanism cleans impurities from the inner wall of the expansion joint. At this time, the measuring mechanism moves to the expansion joint position that has been cleaned by the cleaning mechanism, and adjusts the measuring mechanism to detect the width of the expansion joint. If the state of the measuring mechanism does not change, the marking mechanism does not mark the expansion joint, indicating that the width of the expansion joint at this location is normal. If the state of the measuring mechanism changes, the measuring mechanism will drive the marking mechanism to move, and the marking mechanism will mark the expansion joint, so that subsequent personnel can repair the expansion joint according to its condition.

[0009] Optionally, the cleaning mechanism includes at least two cleaning plates, a drive assembly, and a power assembly; the power assembly includes a power screw, multiple power supports, a power motor, and a first bevel gear set corresponding to the power supports; the power screw is rotatably connected to the starting end, and the axial direction of the power screw is perpendicular to the movement direction of the detection frame; the power screw has a positive thread section and a negative thread section, and the multiple power supports are respectively located on the positive thread section and the negative thread section of the power screw; the first bevel gear set is rotatably connected to the power support through the power motor, wherein the axial direction of the output shaft of the power motor is perpendicular to the movement direction of the detection frame; the cleaning plate is connected to the first bevel gear set; the drive assembly is used to drive the power screw to rotate, so that the cleaning plate contacts the side wall of the expansion joint.

[0010] By adopting the above technical solution, when it is necessary to clean the sidewall of the expansion joint, the drive assembly is adjusted, which drives the power screw to rotate. The rotation of the power screw drives the power supports located at both ends to move. The power supports move closer to the inner wall of the expansion joint, and the movement of the power supports drives the cleaning plate to move. The cleaning plate contacts the inner wall of the expansion joint, and the power motor is turned on. The power motor drives the first bevel gear set to rotate, and the rotation of the first bevel gear set drives the cleaning plate to move. The movement of the cleaning plate swings and removes impurities on the expansion joint, realizing the cleaning of impurities in the first direction on the expansion joint. The detection frame is pushed forward, and the detection frame moves forward inside the expansion joint. The movement of the detection frame drives the cleaning plate to move forward, and the forward movement of the cleaning plate realizes the cleaning of impurities in the second direction on the expansion joint, thereby realizing the all-round cleaning of impurities on the inner wall of the expansion joint, thus improving the accuracy of detecting the change in the expansion joint.

[0011] Optionally, the drive assembly includes a drive wheel, a drive bracket, a drive rod, a first belt assembly, and a second belt assembly; the drive bracket is located at the starting end; the drive wheel is rotatably connected to the drive bracket, the drive rod is rotatably connected to the drive bracket, the drive wheel and the drive bracket's shaft are connected to the drive rod via the first belt assembly; the drive rod is connected to the power screw via the second belt assembly.

[0012] By adopting the above technical solution, when it is necessary to drive the power screw to rotate, the drive wheel is rotated, the rotation of the drive wheel drives the first belt group to move, the movement of the second belt group drives the drive rod to rotate, the rotation of the drive rod drives the second belt group to move, and the rotation of the power screw is realized under the action of the second belt group.

[0013] Optionally, the measuring mechanism includes a measuring rod, a first measuring block, a second measuring block, a first spring, and a snap-fit ​​assembly; the measuring rod is connected to the detection frame, and the axial direction of the measuring rod is the same as the width direction of the expansion joint; the first measuring block is movably disposed at one end of the measuring rod, and the first measuring block is connected to the cleaning plate located on the same side; the second measuring block is disposed at the other end of the measuring rod through the first spring; the snap-fit ​​assembly is disposed on the detection bracket and is used to fix the second measuring block; the second measuring block is connected to the marking mechanism and is used to drive the marking mechanism to move; wherein, the measuring mechanism has a measuring state, in which the snap-fit ​​assembly is opened, the second measuring block is away from the first measuring block, and the second measuring block contacts the side wall of the expansion joint.

[0014] By adopting the above technical solution, when the measuring mechanism measures the change in the expansion joint, since the first measuring block is connected to the cleaning plate on the same side, the movement of the cleaning plate allows the first measuring block to be in close contact with the side wall of the expansion joint. When the first measuring block is in close contact with the side wall of the expansion joint, the snap-fit ​​assembly is activated. Under the action of the snap-fit ​​assembly, the second measuring block tends to move closer to the side wall of the expansion joint (if there is a change in the width between the expansion joints, the second measuring block tends to move closer to the side wall of the expansion joint; it can be understood that, in the initial state, the distance between the first and second measuring blocks is set to the normal state of the expansion joint width). The movement of the second measuring block drives the marking mechanism to move, and the marking mechanism marks the expansion joint at that location, which facilitates subsequent maintenance by the staff.

[0015] Optionally, the latching assembly includes a latching block, a latching spring, a latching rotating rod, and a latching lock; one end of the latching block is rotatably connected to the detection frame via the latching spring; the latching rotating rod is connected to the second measuring block, and the latching rotating rod is slidably connected to the detection frame and can rotate along its own axis; the latching lock is disposed on the latching rotating rod; the latching assembly has a latching state, and under the action of the second measuring block, the latching rotating rod drives the latching lock to approach the latching block, and the latching lock latches with the latching block.

[0016] By adopting the above technical solution, when it is necessary to detect the change in the expansion joint, the buckle rod is rotated. The rotation of the buckle rod causes the buckle lock to rotate, and the rotation of the buckle lock causes it to separate from the buckle block. At this time, under the action of the first spring, the second measuring block approaches the side wall of the expansion joint, thus completing the measurement of the change in the width of the expansion joint. After the measurement is completed, the second measuring block is pushed. The movement of the second measuring block causes the buckle rod to move, and the movement of the buckle rod causes the buckle lock to move. The buckle lock approaches the buckle block, and the buckle block engages with the buckle block under the action of the buckle spring. This allows the second measuring block to return to its original position, facilitating the detection of the change in the expansion joint at the next location.

[0017] Optionally, the marking mechanism includes a plurality of marking components arranged along the length of the detection frame, a control component corresponding to the marking components, and a drive component that drives the control component to move; the control component is connected to the second measuring block through the drive component, and the drive component drives the control component to move under the movement of the second measuring block; the control component is used to drive the marking components to move.

[0018] By adopting the above technical solution, when the second measuring block moves, the movement of the second measuring block drives the component to move, and the movement of the component drives the control component to move. Under the action of the control component, the marking component moves, and the marking component marks the area where the expansion joint has abnormalities, so as to facilitate timely maintenance by the staff later.

[0019] Optionally, the control component includes a control lever, multiple second bevel gear sets, a control screw, a control block, and a control switch; the control lever is rotatably connected to the detection frame, and the axial direction of the control lever is the same as the movement direction of the detection frame; the driving component is used to drive the control lever to rotate; the multiple second bevel gear sets are evenly distributed along the length direction of the control lever; the control screw is connected to the corresponding second bevel gear set; the control block is threadedly connected to the control screw and slidably connected to the detection frame; the control switch is disposed on the detection frame, corresponding to the control block, and the control block can contact the control switch, wherein the control component is turned on or off under the action of the control switch, and the control switch is used to control the movement of the marking component.

[0020] By adopting the above technical solution, the second measuring block moves, which drives the component to move, which in turn drives the control rod to rotate. The rotation of the control rod drives multiple second bevel gear sets on it to move, which in turn drives the corresponding control screw to rotate. The rotation of the control screw drives the control block to move, and the control block contacts the control switch. At this time, the control switch is in the open state, and the control switch generates a control signal. The control signal causes the marking component to move, and the marking component marks the location where there is an abnormality in the expansion joint.

[0021] Optionally, the driving assembly includes a driving block, a driving rack, and a driving gear; the driving block is connected to the second measuring block; the driving rack is disposed on the driving block, and the direction of movement of the driving rack is the same as the width direction of the expansion joint; the driving gear is disposed on the control lever, and the driving gear meshes with the driving rack.

[0022] By adopting the above technical solution, due to the abnormality of the expansion joint, the second measuring block moves, the movement of the second measuring block drives the movement of the drive block, the movement of the drive block drives the movement of the rack, the movement of the rack drives the movement of the gear, and the movement of the gear drives the movement of the control rod, thereby achieving the purpose of driving the movement of the marking component through the movement of the second measuring block.

[0023] Optionally, the marking assembly includes a marking screw, a marking motor, a marking block, and a marking pen; the marking screw is rotatably connected to the detection frame, and the axis of the marking screw is perpendicular to the movement direction of the detection frame; the marking block is threadedly connected to the marking screw and slidably connected to the detection frame; the marking pen is connected to the marking block and can contact the surface of the expansion joint; the marking motor is activated under the action of the control assembly to drive the marking screw to rotate.

[0024] By adopting the above technical solution, when the control block contacts the control switch, the control switch is in the open state. The control switch generates a control signal, and the opening of the control switch causes the marking motor to move. The movement of the marking motor drives the marking screw to rotate. The rotation of the marking screw causes the marking block to descend on the detection frame. The movement of the marking block drives the marking pen to move. The marking pen contacts the expansion joint, thereby achieving the purpose of marking the expansion joint.

[0025] Optionally, the cleaning mechanism further includes a cleaning frame and an adsorption component; the cleaning frame is located at the starting end and has a discharge port located directly below the cleaning plate; the adsorption component is used to adsorb and clean impurities inside the cleaning frame.

[0026] By adopting the above technical solution, when the detection frame is pushed forward and the cleaning plate rotates with the first bevel gear set, the impurities attached to the side wall of the expansion joint are cleaned by the cleaning plate. The cleaned impurities enter the cleaning frame through the discharge port, and the adsorption component is activated to adsorb the impurities in the cleaning frame.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. By moving the inspection frame to the expansion joint measurement position, pushing the inspection bracket, the inspection bracket drives the cleaning mechanism to move. Adjusting the cleaning mechanism, the cleaning mechanism cleans the impurities on the inner wall of the expansion joint. At this time, the measuring mechanism moves to the expansion joint position cleaned by the cleaning mechanism, and adjusts the measuring mechanism to detect the width of the expansion joint. If the state of the measuring mechanism does not change, the marking mechanism does not mark the expansion joint, indicating that the width of the expansion joint at this point is normal. If the state of the measuring mechanism changes, the measuring mechanism will drive the marking mechanism to move, and the marking mechanism will mark the expansion joint so that subsequent staff can repair the expansion joint according to its condition.

[0029] 2. By activating the latching assembly, the second measuring block tends to move closer to the side wall of the expansion joint under the action of the latching assembly (if there is a change in the width between the expansion joints, the second measuring block tends to move closer to the side wall of the expansion joint; it can be understood that in the initial state, the distance between the first measuring block and the second measuring block is set to the normal state of the expansion joint width). The movement of the second measuring block drives the marking mechanism to move, and the marking mechanism marks the expansion joint at that location, which facilitates subsequent maintenance by the staff.

[0030] 3. By rotating the buckle lever, the buckle lever rotates, causing the buckle lock to rotate. The rotation of the buckle lock causes it to separate from the buckle block. At this time, under the action of the first spring, the second measuring block approaches the side wall of the expansion joint, thus completing the measurement of the width change of the expansion joint. After the measurement is completed, push the second measuring block. The movement of the second measuring block drives the buckle lever to move, and the movement of the buckle lever drives the buckle lock to move. The buckle lock approaches the buckle block, and the buckle block engages with the buckle block under the action of the buckle spring. This allows the second measuring block to return to its original position, facilitating the detection of the expansion joint change at the next location.

[0031] 4. The movement of the second measuring block drives the movement of the drive block, which in turn drives the rack, which in turn drives the gear, which in turn drives the control lever, thereby achieving the purpose of driving the marking component to move through the movement of the second measuring block.

Detailed Implementation

[0045] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore detailed descriptions of them will be omitted. Furthermore, the drawings are merely illustrative of this disclosure and are not necessarily drawn to scale.

[0046] See Figure 1 , Figure 2This application discloses a quantitative detection device for changes in expansion joints in water conservancy projects. The testing equipment includes a testing frame 1, moving wheels 2, a cleaning mechanism 3, a measuring mechanism 4, and a marking mechanism 5. The moving wheels 2 are mounted on the testing frame 1 to facilitate the movement of the testing frame 1 along the length of the expansion joint 6. The testing frame 1 has a starting end 11 and an ending end 12. The cleaning mechanism 3 is located at the starting end 11 and is used to clean impurities from the inner wall of the expansion joint 6. It is understood that when detecting the change in the expansion joint 6, the cleaning mechanism 3 is located inside the expansion joint 6. By moving the testing frame 1, the testing frame 1 drives the cleaning mechanism 3 to move, and the cleaning mechanism 3 cleans the inner wall of the expansion joint 6. The measuring mechanism 4 is mounted on the testing frame 1, located between the starting end 11 and the ending end 12, and is used to detect the width of the expansion joint 6. After the cleaning mechanism 3 has cleaned the inner wall of the expansion joint 6, the measuring mechanism 4 moves to the cleaned position of the expansion joint 6 under the drive of the testing frame 1, and measures this position. The marking mechanism 5 is connected to the measuring mechanism 4 and is used to mark the corresponding position of the expansion joint 6 according to the state of the measuring mechanism 4.

[0047] See Figure 2 , Figure 3 In some embodiments, the cleaning mechanism 3 includes at least two cleaning plates 31, a drive assembly 32, and a power assembly 33. The cleaning plates 31 are connected to the power assembly 33, which drives the cleaning plates 31 to move so that multiple cleaning plates 31 can contact the sidewall of the expansion joint 6. At the same time, the power assembly 33 is configured to make the cleaning plates 31 applicable to expansion joints 6 of different specifications, thereby improving the applicability of the detection equipment. The power assembly 33 is connected to the drive assembly 32, which drives the power assembly 33 to move so that the cleaning plates 31 can contact the sidewall of the expansion joint 6.

[0048] In this embodiment, see Figure 2 , Figure 6 , Figure 7 as well as Figure 8 The power assembly 33 includes a power screw 331, multiple power supports 332, a power motor 333, and a first bevel gear set 334 corresponding to the power supports 332. The power screw 331 is rotatably connected to the starting end 11, and the axial direction of the power screw 331 is perpendicular to the movement direction of the detection frame 1. The power screw 331 has a positive thread section and a negative thread section, and the multiple power supports 332 are respectively located on the positive thread section and the negative thread section of the power screw 331. The first bevel gear set 334 is rotatably connected to the power support 332 through the power motor 333, wherein the axial direction of the output shaft of the power motor 333 is perpendicular to the movement direction of the detection frame 1. The cleaning plate 31 is connected to the first bevel gear set 334. The drive assembly 32 is used to drive the power screw 331 to rotate, so that the cleaning plate 31 contacts the side wall of the expansion joint 6.

[0049] As an example, see Figure 8 The first bevel gear set 334 includes a first driving bevel gear 3341 and a first driven bevel gear 3342; the first driving bevel gear 3341 is rotatably connected to one side of the power support 332 via a power motor 333, and the first driven bevel gear 3342 is connected to the other side of the power support 332, and the first driving bevel gear 3341 and the first driven bevel gear 3342 mesh; the power motor 333 is used to drive the first driving bevel gear 3341 to rotate.

[0050] Specifically, when the power assembly 33 drives the cleaning plate 31 to contact the side wall of the expansion joint 6, the power motor 333 is turned on. The rotation of the power motor 333 drives the first active bevel gear 3341 to rotate, which in turn drives the first driven bevel gear 3342 to rotate. The rotation of the first driven bevel gear 3342 drives the cleaning plate 31 to rotate. The cleaning plate 31 rotates on the side wall of the expansion joint 6 to clean the impurities on the side wall of the expansion joint 6. This configuration enables the cleaning of firmly attached impurities (such as mud and sand) on the expansion joint 6, thereby improving the detection accuracy of the detection equipment.

[0051] In some embodiments of this disclosure, see Figure 6 , Figure 7 The drive assembly 32 includes a drive wheel 321, a drive bracket 322, a drive rod 323, a first belt assembly 324, and a second belt assembly 325. The drive bracket 322 is located at the starting end 11. The drive wheel 321 is rotatably connected to the drive bracket 322, and the drive rod 323 is rotatably connected to the drive bracket 322. The shafts of the drive wheel 321 and the drive bracket 322 are connected to the drive rod 323 via the first belt assembly 324. The drive rod 323 is connected to the power screw 331 via the second belt assembly 325. When it is necessary to drive the power screw 331 to rotate, the drive wheel 321 is rotated, which drives the first belt assembly 324 to move. The movement of the first belt assembly 324 drives the drive rod 323 to move, which in turn drives the second belt assembly 325 to move. The second belt assembly 325 then drives the power screw 331 to move, thus achieving the purpose of driving the power screw 331 to move.

[0052] As an example, see Figure 6 , Figure 7The first belt assembly 324 includes a first driving pulley 3241, a first driven pulley 3242, and a first connecting belt 3243; wherein, the first driving pulley 3241 is connected to the shaft of the drive wheel 321 and the drive bracket 322, the first driven pulley 3242 is connected to the drive rod 323, and the first connecting belt 3243 is sleeved on the first driving pulley 3241 and the first driven pulley 3242.

[0053] As another example, see Figure 6 , Figure 7 The second belt assembly 325 includes a second driving pulley 3251, a second driven pulley 3252, and a second connecting belt 3253; wherein, the second driving pulley 3251 is connected to the drive rod 323, the second driven pulley 3252 is connected to the power screw 331, and the second connecting belt 3253 is sleeved on the second driving pulley 3251 and the second driven pulley 3252.

[0054] In some embodiments of this disclosure, see Figure 2 , Figure 6 The cleaning mechanism 3 also includes a cleaning frame 34 and an adsorption component 35. The cleaning frame 34 is located at the starting end 11 and has a discharge port 341, which is located directly below the cleaning plate 31. The adsorption component 35 is used to adsorb and clean the impurities inside the cleaning frame 34. After the cleaning plate 31 cleans the impurities on the side wall of the expansion joint 6, the cleaned impurities fall into the cleaning frame 34 through the discharge port 341. Under the action of the adsorption component 35, the impurities inside the cleaning frame 34 are adsorbed, so that the cleaning frame 34 is cleaned at all times, reducing the need for manual cleaning of the cleaning frame 34 and thus improving the detection efficiency of the change in the expansion joint 6.

[0055] It is understandable that the function of the adsorption component 35 is to clean the impurities in the cleaning frame 34 by generating negative pressure. The adsorption component 35 is a technology well known to those skilled in the art, and this application will not elaborate on it.

[0056] In some embodiments of this disclosure, see Figure 1 , Figure 2 , Figure 3 , Figure 4The measuring mechanism 4 includes a measuring rod 41, a first measuring block 42, a second measuring block 43, a first spring 44, and a latching assembly 45. The measuring rod 41 is connected to the detection frame 1, and the axial direction of the measuring rod 41 is the same as the width direction of the expansion joint 6. The first measuring block 42 is movably disposed at one end of the measuring rod 41 and is connected to the cleaning plate 31 located on the same side. Thus, when the cleaning plate 31 contacts the side wall of the expansion joint 6, one side of the first measuring block 42 can be tightly attached to the side wall of the expansion joint 6. The second measuring block 43 is disposed at the other end of the measuring rod 41 via the first spring 44. The latching assembly 45 is disposed on the detection frame 1 and is used to fix the second measuring block 43. The second measuring block 43 is connected to the marking mechanism 5 and is used to drive the marking mechanism 5 to move. The measuring mechanism 4 has a measuring state. In the measuring state, the latching assembly 45 is opened, the second measuring block 43 moves away from the first measuring block 42, and the second measuring block 43 contacts the side wall of the expansion joint 6.

[0057] It is understood that in this embodiment, the measuring mechanism 4 has two states: an initial state and a measuring state. In the initial state, the second measuring block 43 maintains a normal distance from the first measuring block 42 under the action of the snap-fit ​​assembly 45. This normal distance is the qualified distance under the construction specifications of the expansion joint 6. In the measuring state, under the action of the snap-fit ​​assembly 45, the second measuring block 43 moves to the side closer to the expansion joint 6 (this only describes the situation where the expansion joint 6 is expanding; of course, the expansion joint 6 may have a narrowing problem. When the expansion joint 6 has a narrowing problem, the measuring mechanism 4 cannot extend into the expansion joint 6, which is not considered in this application). The movement of the second measuring block 43 will drive the movement of the marking mechanism 5, thereby marking the abnormal area of ​​the expansion joint 6.

[0058] In this embodiment, see Figure 2 , Figure 3 , Figure 4 , Figure 5 The latching assembly 45 includes a latching block 451, a latching spring 452, a latching rotating rod 453, and a latching lock 454. One end of the latching block 451 is rotatably connected to the detection frame 1 via the latching spring 452. The axial direction of the rotation axis of the latching block 451 and the detection frame 1 is perpendicular to the direction of movement of the detection frame 1. The latching rotating rod 453 is connected to the second measuring block 43 and is slidably connected to the detection frame 1. It can be understood that the movement of the second measuring block 43 can drive the latching rotating rod 453 to slide on the detection frame 1. The latching lock 454 is provided on the latching rotating rod 453. The latching assembly 45 has a latching state. Under the action of the second measuring block 43, the latching rotating rod 453 drives the latching lock 454 to approach the latching block 451, and the latching lock 454 latches with the latching block 451.

[0059] Furthermore, the buckle assembly 45 has a released state. When it is necessary to measure the change in the expansion joint 6, the buckle rotating rod 453 is rotated. The rotation of the buckle rotating rod 453 drives the buckle lock 454 to rotate. The rotation of the buckle lock 454 causes the buckle lock 454 to be released from the buckle block 451. Under the action of the first spring 44, the second measuring block 43 approaches the side wall of the expansion joint 6 to realize the measurement of the change in the expansion joint 6.

[0060] Furthermore, see Figure 5 A snap-locking torsion spring 455 can also be fitted on the snap-locking rod 453. When the snap-locking rod 453 rotates, it can automatically return to its original position under the action of the snap-locking torsion spring 455, which can realize the quick locking and unlocking of the second measuring block 43.

[0061] In some embodiments of this disclosure, see Figure 2 , Figure 6 as well as Figure 9 The marking mechanism 5 includes multiple marking components 51 arranged along the length of the detection frame 1, a control component 52 corresponding to the marking components 51, and a driving component 53 that drives the control component 52 to move. The control component 52 is connected to the second measuring block 43 through the driving component 53, and the driving component 53 drives the control component 52 to move under the movement of the second measuring block 43. The control component 52 is used to drive the marking components 51 to move.

[0062] Specifically, due to the change in the width of the expansion joint 6, when the first measuring block 42 and the second measuring block 43 enter the expansion joint 6 (the first measuring block 42 is pressed against the side wall of the expansion joint 6), the second measuring block 43 approaches the side wall of the expansion joint 6 under the action of the first spring 44. The movement of the second measuring block 43 drives the component 53 to move, which in turn drives the control component 52 to move, and the movement of the control component 52 drives the marking component 51 to move, thereby marking the location of the expansion joint 6 for subsequent handling by staff.

[0063] In some embodiments of this disclosure, the control component 52 includes a control lever 521, a plurality of second bevel gear sets 522, a control screw 523, a control block 524, and a control switch 525. The control lever 521 is rotatably connected to the detection frame 1, and the axial direction of the control lever 521 is the same as the direction of movement of the detection frame 1. The driving component 53 is connected to the control lever 521 and is used to drive the control lever 521 to rotate. The plurality of second bevel gear sets 522 are evenly distributed along the length direction of the control lever 521. The control screw 523 is connected to the corresponding second bevel gear set 522. The control block 524 is threadedly connected to the control screw 523 and slidably connected to the detection frame 1. The control switch 525 is disposed on the detection frame 1, and the control switch 525 is correspondingly disposed with the control block 524, and the control block 524 can contact the control switch 525. The control component 52 is turned on or off under the action of the control switch 525, and the control switch 525 is used to control the movement of the marking component 51.

[0064] As an example, see Figure 6Three sets of second bevel gear sets 522 can be arranged along the axial direction of the control screw 523. It is understood that in other embodiments, the number of second bevel gear sets 522 is not limited to this. Each of the three sets of second bevel gear sets 522 corresponds to one of the three control screws 523. Each of the three control screws 523 has a corresponding control block 524 and a control switch 525 arranged on the detection frame 1, corresponding to each of the three control blocks 524. The distances between the three control blocks 524 and the control switches 525 are different, meaning that when the three control screws 523 rotate, some control blocks 524 will contact the control switches 525, while others will not. Specifically, when the control screw 523 rotates a small circle, the control block 524 closest to the control switch 525 contacts the control switch 525, generating a control signal. This control signal controls the movement of its corresponding marking component 51, which marks the expansion joint 6 (the marking indicates that the change in the expansion joint 6 is within an acceptable range). When the control screw 523 rotates a moderate circle, some control blocks 524 contact their corresponding control switches 525, which send a control signal. This control signal drives the control component 52 to move, which in turn drives the marking component 51 to move. The marking component 51 then marks the expansion joint 6 (the marking indicates that changes in the expansion joint 6 should be taken seriously). When the control screw 523 rotates a large circle, all control blocks 524 contact their corresponding control switches 525, which send a control signal. This control signal drives the control component 52 to move, which in turn drives the marking component 51 to move. The marking component 51 then marks the expansion joint 6 (the marking indicates that changes in the expansion joint 6 should be repaired). This setup allows for accurate determination of the change in the expansion joint 6, while also guiding subsequent maintenance.

[0065] As an example, see Figure 6 , Figure 9 The second bevel gear set 522 may include a second driving bevel gear 5221 and a second driven bevel gear 5222; wherein, the second driving bevel gear 5221 is fixed to the control rod 521 by a key connection, and the second driven bevel gear 5222 is fixed to the control screw 523 by a key connection, and the second driving bevel gear 5221 and the second driven bevel gear 5222 mesh.

[0066] In some embodiments of this disclosure, see Figure 2 , Figure 3 as well as Figure 4The drive assembly 53 includes a drive block 531, a drive rack 532, and a drive gear 533; the drive block 531 is connected to the second measuring block 43; the drive rack 532 is mounted on the drive block 531, and the direction of movement of the drive rack 532 is the same as the width direction of the expansion joint 6; the drive gear 533 is mounted on the control lever 521, and the drive gear 533 meshes with the drive rack 532. Specifically, when the width of the expansion joint 6 changes, the second measuring block 43 moves. The movement of the second measuring block 43 drives the rack 532 to move, which in turn drives the gear 533 to move. The rotation of the gear 533 drives the control rod 521 to rotate, which in turn drives the multiple second bevel gear sets 522 on it to move. The movement of the second bevel gear sets 522 causes the control screw 523 to rotate, which in turn causes the control block 524 to move. The control block 524 then contacts the control switch 525, thereby achieving the purpose of driving the marking component 51 to move.

[0067] In some embodiments of this disclosure, see Figure 6 , Figure 10 The marking component 51 includes a marking screw 511, a marking motor 512, a marking block 513, and a marking pen 514. The marking screw 511 is rotatably connected to the detection frame 1, and the axis of the marking screw 511 is perpendicular to the movement direction of the detection frame 1. The marking block 513 is threadedly connected to the marking screw 511 and slidably connected to the detection frame 1. The marking pen 514 is connected to the marking block 513 and can contact the surface of the expansion joint 6. The marking motor 512 is turned on under the action of the control component 52 to drive the marking screw 511 to rotate.

[0068] It is understood that by turning on the control switch 525, the control switch 525 sends a signal to control the movement of the identification motor 512. This technology is well known to those skilled in the art, and will not be described in detail here.

This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only, and the true scope and spirit of this disclosure are indicated by the appended claims.
