Description

Technical Field

[0001] This invention relates to the field of crack measurement technology, and more specifically, to an adjustable clamp-type measuring device for monitoring surface cracks on slopes. Background Technology

[0002] In slope surface crack monitoring, the core purpose of measuring crack width is to provide key data support for slope stability assessment, disaster early warning and engineering management by observing the dynamic changes in crack width. Especially when the slope is affected by external factors such as rainfall, earthquakes and artificial excavation, the soil and rock mass may creep or slide, leading to the expansion of crack width. Therefore, it is particularly important to use measuring devices to measure crack width changes.

[0003] Among the existing publicly available documents, patent publication number CN109855544A discloses a surface crack monitoring device based on laser ranging. This technology allows for measurement by simply adjusting the base so that the laser point falls precisely on the center area of ​​the alignment plate. Simultaneously, the measurement can be completed from a distance from the crack, eliminating the need to enter the crack's interior and ensuring the personnel's safety. However, this technology still has the following drawbacks.

[0004] In monitoring and measuring the width of surface cracks on slopes, continuous measurement over a long period of time is required. However, when operators are far from the measuring device, the width measuring part and the installation part of the measuring device are exposed, which has obvious drawbacks. Non-professionals can easily tamper with the measurement data and can also disassemble the installation part, causing the measurement to deviate. It is difficult to carry out self-protection measurement of the width measuring part and the installation part of the measuring device simultaneously. This makes the width measurement data lack reliable protection and is very easy to be accidentally tampered with by external human factors, which leads to large measurement errors. Summary of the Invention

[0015] Multiple protective teeth are fixed to the outer wall of the fixed shell;

[0016] A fixing sleeve is fixed to one end of a housing. The outer wall of the fixing sleeve is equipped with multiple protective teeth, which are slidably connected to the inner wall of the fixing sleeve.

[0017] In a preferred embodiment, the length of the sleeve is less than the length of the cover shell, and the length of the fixing sleeve is less than the length of the fixing shell.

[0018] In a preferred embodiment, a plurality of the protective teeth are arranged sequentially from left to right, with a gap between adjacent protective teeth.

Both the frame strip and the inclined pressure strip are fixedly connected to the support strip.

[0024] In a preferred embodiment, both the diagonal strip and the fitting cover are slidably connected to the mounting block, and the two fitting covers are symmetrically arranged about the linkage strip.

[0025] In a preferred embodiment, two guide rods are installed at the top of the inner wall of the fitting cover and near the diagonal strip, the guide rods being used to slide along the inner wall of the mounting block.

[0026] In a preferred embodiment, a battery and a wireless controller are provided below the frame strip, and both the wireless controller and the battery are fixedly connected to the mounting block, and the battery and the wireless controller are electrically connected to each other.

[0027] The technical effects and advantages of the present invention.

[0028] 1. This invention employs a self-protection adjustment component and a drive protection component working in tandem. Compared to existing technologies, when the drive protection component is activated, the self-protection adjustment component simultaneously drives the covering shell to surround the outside of the measuring rod, and the sleeve shell to surround the outside of the measuring sleeve. At the same time, the drive protection component causes the fitting cover to move vertically downward and lock, completely covering the two mounting blocks. This achieves synchronous and automated protection of the width measuring component and the two mounting blocks, simultaneously encapsulating the core width measuring component and the two mounting blocks within a protected area. This effectively prevents unauthorized personnel from tampering with the measurement data and from disassembling and damaging the installation parts, fundamentally ensuring the authenticity and reliability of the slope surface crack width measurement data and significantly reducing width measurement errors.

[0029] 2. When the crack expands and the distance between the two mounting blocks increases, the cover shell and the sleeve shell, as well as the fixed shell and the fixed sleeve, will slide and expand accordingly, always maintaining complete coverage of the measuring rod and the outside of the measuring sleeve. This ensures that the protection function will not fail due to the displacement of the width measuring component itself at any measurement and monitoring stage, achieving continuous and uninterrupted passive protection. It avoids measurement errors caused by the rigidity of the protection structure, fundamentally ensuring the authenticity and reliability of the slope surface crack width measurement data, and significantly reducing width measurement errors.

[0030] 3. This invention employs protective teeth on the fixed shell and protective teeth on the fixed sleeve, combined with a mechanical locking mechanism of oblique teeth and pressure teeth. This allows the protective teeth to physically deter and hinder human contact and destructive behavior. Meanwhile, the pressure teeth mesh with the oblique teeth during the driving process, firmly locking the cover to the mounting block, forming a protective area that is difficult to forcibly open from the outside. This dual protection technology, combining deterrent physical protection with active mechanical locking, greatly enhances the overall anti-interference capability and safety of the slope surface crack width measurement device, fundamentally ensuring the authenticity and reliability of the slope surface crack width measurement data, and significantly reducing width measurement errors.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] like Figure 1 - Figure 8 The adjustable clamp-type measuring device for monitoring surface cracks on slopes, as shown, includes two mounting blocks 1, with a width measuring component installed between the two mounting blocks 1. The width measuring component is used to measure the width of surface cracks on slopes. A self-protecting adjustment component is located outside the width measuring component, and a frame strip 5 is provided on the self-protecting adjustment component. A driving protection component is located outside the frame strip 5, and multiple fitting covers 19 are provided on the driving protection component. The driving protection component drives the multiple fitting covers 19 to move vertically, so that each fitting cover 19 covers and locks onto the two mounting blocks 1, forming a protective area outside the two mounting blocks 1. At the same time, the driving protection component drives the frame strip 5 to rotate, and the frame strip 5 drives the self-protecting adjustment component to surround the width measuring component, synchronously forming a protective area outside the width measuring component. During this period, the self-protecting adjustment component adaptively adjusts its own length according to the length of the width measuring component to achieve effective protection of the width measuring component.

[0042] In this embodiment, as Figure 1 - Figure 3As shown, the width measurement component includes: a measuring rod 2, positioned between two mounting blocks 1; a measuring sleeve 3 slidably connected to the outer wall of the measuring rod 2; and a distance sensor 4 installed on one side of the inner wall of the measuring sleeve 3, used to measure the movement distance of the measuring rod 2. The measuring rod 2 is fixedly connected to the mounting blocks 1, and the measuring sleeve 3 is fixedly connected to the other mounting block 1. When the surface cracks on the slope increase in size, the tension of the surface cracks will cause the distance between the two mounting blocks 1 to increase. The mounting blocks 1 drive the measuring rod 2 to move along the inside of the measuring sleeve 3. The distance sensor 4 senses the distance between the measuring sleeve 3 and the distance sensor 4. The sensed change in distance is the change in the width of the surface cracks on the slope, enabling the measurement of the width of the surface cracks on the slope and allowing for continuous monitoring.

[0043] In this embodiment, as Figure 2 - Figure 6 As shown, the self-protection adjustment assembly includes: a displacement shaft 6, which slides on the inner wall of the frame strip 5; a groove 7 is provided on the inner wall of the mounting block 1 and outside the displacement shaft 6, the groove 7 being used to guide the displacement shaft 6 to slide; a cover shell 8, fixed to one end of the displacement shaft 6; a sleeve shell 9 is provided on the outer wall of the cover shell 8; the cover shell 8 and the sleeve shell 9 are slidably connected; a fixed shell 10 is slidably connected to the outside of the sleeve shell 9; multiple protective teeth 11, all fixed to the outer wall of the fixed shell 10; a fixed sleeve 12, fixed to one end of the sleeve shell 9; multiple protective teeth 13 are installed on the outer wall of the fixed sleeve 12; the protective teeth 11 are slidably connected to the inner wall of the fixed sleeve 12; the fixed shell 10 is fixedly connected to the mounting block 1; and the fixed sleeve 12 is fixedly connected to another mounting block 1. The length of the sleeve shell 9 is less than the length of the cover shell 8, and the length of the fixed sleeve 12 is less than the length of the fixed shell 10. The multiple protective teeth 11 are arranged sequentially from left to right, with a gap between adjacent protective teeth 11.

[0044] In operation, the frame 5 rotates counterclockwise, causing the displacement shaft 6 to rotate counterclockwise along the inner wall of the slide groove 7. The displacement shaft 6 then causes the cover shell 8 to rotate counterclockwise, and the sleeve shell 9 to rotate counterclockwise along the inside of the fixed shell 10. Thus, the cover shell 8 surrounds the outer area of ​​the measuring rod 2, and the sleeve shell 9 surrounds the outer wall area of ​​the measuring sleeve 3. When the distance between the two mounting blocks 1 increases, the mounting blocks 1 cause the displacement shaft 6 to move to the left, the cover shell 8 to move to the left along the inside of the sleeve shell 9, and the fixed shell 10 to slide to the left along the outer wall of the sleeve shell 9. The fixed shell 10 also causes multiple protective teeth 11 to move to the left. The sleeve shell 9 and the cover shell 8 can continuously adaptively adjust their length according to the length changes between the measuring rod 2 and the measuring sleeve 3. Similarly, the fixed sleeve 12 and the fixed shell 10 can continuously adaptively adjust their length according to the length changes between the measuring rod 2 and the measuring sleeve 3. This provides adaptive adjustment protection, preventing interference from human factors in width measurement.

[0045] In this embodiment, as Figure 4 - Figure 8 As shown, the drive protection assembly includes: a drive shaft 14, fixed to the outer wall of the frame 5, with a reduction gear 15 installed at one end of the drive shaft 14. The reduction gear 15 is used to drive the drive shaft 14 to rotate, and the outer wall of the reduction gear 15 is fixedly connected to the mounting block 1; a separation strip 16, fixed to the outer wall of the drive shaft 14, with a diagonal strip 17 attached to the upper surface of the separation strip 16, and multiple diagonal teeth 18 installed on one inclined surface of the diagonal strip 17. The top end of the diagonal strip 17 is fixedly connected to the top end of the inner wall of the fitting cover 19; a linkage strip 20, installed on the upper surface of the fitting cover 19, with both fitting covers 19 fixedly connected to the linkage strip 20; and a diagonal pressure strip 21, fixed to the outer wall of the frame 5 and located away from the drive shaft 14. Multiple pressure teeth 22 are installed on the upper inclined surface of the diagonal pressure strip 21, and a support strip 23 is provided on the lower inclined surface of the diagonal pressure strip 21. Both the frame 5 and the diagonal pressure strip 21 are fixedly connected to the support strip 23. Both the diagonal strip 17 and the fitting cover 19 are slidably connected to the mounting block 1, and the two fitting covers 19 are symmetrically arranged about the linkage strip 20.

[0046] In operation, the reduction gear servo 15 starts the drive shaft 14 to rotate counterclockwise. The drive shaft 14 causes the separation bar 16 to no longer contact the bottom end of the inclined bar 17. The bonding cover 19 drives the linkage bar 20 to move downward, and the linkage bar 20 drives another bonding cover 19 to move downward synchronously. The bonding cover 19 drives the inclined bar 17 to move downward, and multiple helical teeth 18 move downward until the top surface of the inner wall of the bonding cover 19 is in contact with the upper surface of the mounting block 1. The two bonding covers 19 form a protective area outside the two mounting blocks 1, achieving synchronous protection drive. Furthermore, when the frame bar 5 rotates counterclockwise, it will drive the support bar 23 to rotate counterclockwise simultaneously. The inclined pressure bar 21 drives multiple pressure teeth 22 to rotate counterclockwise. The multiple pressure teeth 22 rotate counterclockwise and press against the right inclined surface of the inclined bar 17. The multiple pressure teeth 22 mesh with the inclined teeth 18 and press and lock the multiple inclined teeth 18. The multiple inclined teeth 18 lock the inclined bar 17, and finally achieve the locking and fitting of the inclined bar 17 to the cover 19. This can protect the outside of the mounting block 1 and prevent non-professionals from disassembling and changing the position of the mounting block 1.

[0047] In this embodiment, as Figure 7 As shown, two guide rods 26 are installed at the top of the inner wall of the fitting cover 19 and near the diagonal strip 17. The guide rods 26 are used to slide along the inner wall of the mounting block 1. The fitting cover 19 drives the two guide rods 26 to move downward, and the guide rods 26 guide the downward movement along the inner wall of the mounting block 1 to ensure that the fitting cover 19 moves vertically downward.

[0048] In this embodiment, as Figure 7As shown, a battery 24 and a wireless controller 25 are located below the frame 5. Both the wireless controller 25 and the battery 24 are fixedly connected to the mounting block 1, and the battery 24 and the wireless controller 25 are electrically connected. The wireless controller 25 is powered by the battery 24, which enables the wireless controller 25 to start the reduction gear servo 15 and realize the transmission control of the reduction gear servo 15.

[0049] The working principle of the adjustable clamp-type measuring device for monitoring surface cracks on slopes in this invention is as follows.

[0050] First, during the adjustment and snap-fit ​​installation of this invention, by pulling the mounting block 1 to the left, the mounting block 1 moves the measuring rod 2, and the measuring rod 2 moves from inside the measuring sleeve 3. This increases the distance between the measuring rod 2 and the distance sensor 4, as well as the distance between the two mounting blocks 1. Simultaneously, the mounting block 1 moves the displacement shaft 6 to the left, which in turn moves the covering shell 8 to the left. The covering shell 8 moves to the left along the inside of the sleeve 9, and the mounting block 1 moves the fixing shell 10 to the left. The fixing shell 10 slides to the left along the outer wall of the sleeve 9, and the fixing shell 10 moves multiple protective teeth 11 to the left. Meanwhile, another mounting block 1 supports the fixing sleeve 12, and the fixing sleeve 12 supports the sleeve 9, keeping the sleeve 9 and the fixing sleeve 12 stationary. The measurement position between the two mounting blocks 1 can be adjusted. The two mounting blocks 1 are located on both sides of the surface crack of the slope. The two mounting blocks 1 are fixed to the surface of the slope by using pre-embedded bolts inserted into the holes on the mounting blocks 1, thus completing the adjustment and snap-fit ​​installation operation.

[0051] Secondly, during the drive protection operation, the wireless controller 25 is powered by battery 24. The background remote control starts the wireless controller 25, which in turn starts the deceleration servo 15. The deceleration servo 15 starts the drive shaft 14 to rotate counterclockwise. The drive shaft 14 drives the separation bar 16 to rotate counterclockwise, so the separation bar 16 no longer contacts the bottom end of the inclined bar 17. Thus, under the weight of the bonding cover 19 itself, the bonding cover 19 drives the linkage bar 20 to move downward. The linkage bar 20 drives the other bonding cover 19 to move downward synchronously. The bonding cover 19 also drives the two guide rods 26 to move downward, and the guide rods 26 guide downward along the inner wall of the mounting block 1. At the same time, the bonding cover 19 drives the inclined bar 17 to move downward, and the inclined bar 17 drives multiple inclined teeth 18 to move downward until the top surface of the inner wall of the bonding cover 19 is bonded to the upper surface of the mounting block 1. At this time, the two bonding covers 19 respectively cover the two mounting blocks 1, forming a protective area outside the two mounting blocks 1, and also forming a protective area outside the wireless controller 25.

[0052] At the same time, when the frame bar 5 rotates counterclockwise, it will drive the support bar 23 to rotate counterclockwise in sync. The support bar 23 drives the inclined pressure bar 21 to rotate counterclockwise. The inclined pressure bar 21 drives multiple pressure teeth 22 to rotate counterclockwise. The multiple pressure teeth 22 rotate counterclockwise and press against the right inclined surface of the inclined bar 17. The multiple pressure teeth 22 mesh with the inclined teeth 18 and press, thus pressing and locking the multiple inclined teeth 18. At the same time, the multiple inclined teeth 18 lock the inclined bar 17, and the inclined bar 17 locks and fits the cover 19.

[0053] Meanwhile, when the present invention performs self-protection adjustment, when the frame bar 5 rotates counterclockwise, it will drive the displacement shaft 6 to rotate counterclockwise. The displacement shaft 6 rotates counterclockwise along the inner wall of the slide groove 7 and moves in a guiding manner along the inner wall of the slide groove 7. In this way, the displacement shaft 6 will drive the cover shell 8 to rotate counterclockwise, and the cover shell 8 will drive the sleeve shell 9 to rotate counterclockwise. The sleeve shell 9 rotates counterclockwise along the inside of the fixed shell 10. In this way, the cover shell 8 surrounds the outer upper region of the measuring rod 2, and the sleeve shell 9 surrounds the outer upper region of the measuring sleeve 3. The cover shell 8 and the fixed shell 10 form an enclosing region, and the sleeve shell 9 and the fixed sleeve 12 form an enclosing region. When non-professionals shake or damage the connection between the measuring rod 2 and the measuring sleeve 3, or when their hands are gripping the outer wall of the fixed shell 10, their hands may directly contact the protective teeth 11 and cause injury. Alternatively, if their hands are on the outer wall of the fixed sleeve 12, multiple protective teeth 13 may cause injury to the hands of non-professionals. This ensures that the connection between the measuring rod 2 and the measuring sleeve 3 is protected from external interference, and also prevents the two mounting blocks 1 from being affected by external disassembly or displacement. It also ensures that changes in the distance between the two mounting blocks 1 and between the measuring rod 2 and the measuring sleeve 3 can prevent external interference or tampering with the width monitoring measurement data.

[0054] When the distance between the two mounting blocks 1 increases, the mounting block 1 drives the displacement shaft 6 to move to the left, which in turn drives the cover shell 8 to move to the left. The cover shell 8 moves to the left along the interior of the sleeve shell 9. The mounting block 1 drives the fixing shell 10 to move to the left, which slides to the left along the outer wall of the sleeve shell 9. The fixing shell 10 also drives multiple protective teeth 11 to move to the left. In this way, the sleeve shell 9 and the cover shell 8 can continuously and adaptively adjust their lengths according to the length changes between the measuring rod 2 and the measuring sleeve 3, effectively protecting the upper exterior of the measuring rod 2 and the measuring sleeve 3. Simultaneously, the fixing sleeve 12 and the fixing shell 10 can continuously and adaptively adjust their lengths according to the length changes between the measuring rod 2 and the measuring sleeve 3, effectively protecting the lower exterior of the measuring rod 2 and the measuring sleeve 3.

[0055] Finally, when the present invention is used for measurement, when the cracks on the slope surface become larger, the mounting block 1 drives the measuring rod 2 to move. The measuring rod 2 moves along the inside of the measuring sleeve 3, so that the measuring rod 2 moves away from the distance sensor 4. The distance sensor 4 senses the distance between the measuring sleeve 3 and the distance sensor 4. The value of the sensed distance change is the value of the width change of the cracks on the slope surface. In this way, the width of the cracks on the slope surface can be measured and remotely transmitted to the back-end computer through the wireless controller 25.
