Description

Technical Field

[0001] This application relates to the field of stone testing equipment technology, and more specifically, to a marble edge damage testing device. Background Technology

[0002] Marble slabs, with their naturally beautiful textures, excellent physical properties, and high decorative value, are widely used in core areas such as architectural decoration and interior design. The quality of their construction directly affects the overall aesthetic effect and structural safety. Therefore, random inspection of incoming or soon-to-be-installed marble slabs during the construction phase to check for edge damage is a crucial step in ensuring construction quality. However, marble slabs are highly susceptible to various types of damage during the initial cutting, transportation, and handling processes, manifesting as micro-cracks, chipped edges, and missing corners. Therefore, it is necessary to use specialized damage detection equipment to accurately detect the edge damage of marble slabs during the construction inspection phase, providing core support for construction quality control.

[0003] Currently, the industry's methods for detecting edge damage to marble slabs in construction sampling inspections still have significant shortcomings, making it difficult to meet the flexible and efficient sampling inspection needs of construction sites. Existing detection methods still mainly rely on manual visual observation combined with touch judgment. This method has many inherent defects in construction scenarios: First, the detection efficiency is low. The construction site environment is complex, and the slabs are scattered. Manual inspection must be carried out piece by piece and edge by edge, which cannot match the efficiency requirements of the construction schedule and is likely to delay the construction cycle. Second, the detection results are highly subjective. Different inspectors have different visual sensitivity and experience, resulting in inconsistent detection standards, which can easily lead to misjudgments and omissions. It is difficult to form objective and traceable sampling inspection data, which is not conducive to the whole-process control of construction quality. Third, there are obvious safety hazards. The construction site space is limited and the slabs are densely stacked. When manually touching the edge of the slab, if sharp edges or corners are encountered, it is easy to cause safety accidents such as cuts.

[0004] Although some computer vision-based stone defect detection technologies have emerged, such as edge detection algorithms and texture analysis to identify surface defects, these technologies have clear limitations in construction inspection scenarios: First, their applicability is limited, mainly targeting large-area defect detection on flat surfaces within stone processing workshops, making them unsuitable for the complex environments of construction sites; second, equipment adaptability is severely lacking, with existing detection equipment generally being bulky, complex in structure, and inconvenient to carry, failing to meet the needs of mobile inspections at construction sites, and struggling to achieve close-fitting detection with the edges of marble slabs. This makes edge area image acquisition susceptible to interference from varying lighting conditions and cluttered backgrounds at construction sites, failing to meet the quality requirements of construction inspections.

[0005] In conclusion, the development of a convenient, compact, and portable detection device that can be carried on-site and closely follow the edge of the stone to perform damage detection and simultaneously mark the location of the damage is of great practical significance and application value.

[0006] In view of this, a marble edge damage detection device is proposed. Summary of the Invention

[0007] The purpose of this invention is to provide a marble edge damage detection device to solve the problems mentioned in the background art.

[0008] This invention provides the following technical solution: a marble edge damage detection device, comprising a folding mechanism, a guiding mechanism, a detection marker mechanism, and a recording mechanism; The folding mechanism is used to control the storage of the testing equipment, and includes an opening and closing frame and an adjusting component. The opening and closing frame is disposed between the guide mechanism and the inspection mark mechanism, and the adjusting component is disposed in the middle of the opening and closing frame. The guiding mechanism is used to control the detection equipment to fit closely to the edge of the stone, and includes a frame fixedly connected to the end of the opening and closing frame and a roller rotatably connected to the frame. The inspection and marking mechanism is used to mark the location of damage to the stone edge, and includes a contact element fixedly connected to the slot of the opening and closing frame and a marking element connected to the side wall of the contact element; The recording mechanism is used to monitor and report the damage status of the stone's edges.

[0009] According to the above technical solution, the opening and closing frame includes an arc cylinder fixedly connected to the middle of the adjusting member. Two arc plates are symmetrically slidably connected inside the arc cylinder. A bending seat is fixedly connected to one end of each arc plate. The two bending seats are symmetrically arranged and are respectively connected to the adjusting member and the corresponding mechanism.

[0010] According to the above technical solution, the adjusting component includes a shaft frame sleeved in the middle of the arc cylinder and rotatably engaged with the bending seat. An adjusting screw is rotatably connected to the middle of the shaft frame. The adjusting screw is threaded with a threaded sleeve plate. The threaded sleeve plate is sleeved outside the shaft frame and slidably engaged with the shaft frame. Two toothed plates are arranged symmetrically in a staggered manner on the threaded sleeve plate. A toothed groove ring is engaged on one side of the toothed plate. The toothed groove ring is sleeved on the shaft end of the bending seat.

[0011] According to the above technical solution, the frames are symmetrically arranged at the ends of the opening and closing frame, and the number of rollers rotatably connected in the two frames is different and they are arranged in an inclined cross structure.

[0012] According to the above technical solution, the roller has multiple grooves along the annular structure on its outer side, and a horn-shaped rubber suction cup is fixedly connected in each groove.

[0013] According to the above technical solution, the contact element includes a sleeve frame fixedly connected to the bending seat, and a plurality of elastic telescopic elements are fixedly connected inside the sleeve frame, with the plurality of elastic telescopic elements arranged in a staggered structure.

[0014] According to the above technical solution, the elastic telescopic component includes a piston push rod with universal wheels, a piston cylinder sleeved outside the piston push rod, and a spring component for constraining the two to achieve elastic telescopic movement; one-way inlet valves and one-way outlet valves are symmetrically arranged outside the piston cylinder, and a manifold is fixedly connected between multiple one-way inlet valves through a hose, the manifold is fixedly connected to the side wall of the sleeve frame, and a spray pipe is fixedly connected to the outside of the one-way outlet valve.

[0015] According to the above technical solution, the port of the spray pipe is flush with the bottom of the frame.

[0016] According to the above technical solution, the marking component is a quantitative color developing cylinder for filling marking paint. The quantitative color developing cylinder is a disposable packaging structure and is threadedly connected to the manifold connector.

[0017] According to the above technical solution, the recording mechanism includes a distance sensor, a battery module, and a speaker electrically connected between the distance sensor and the battery module, all fixedly connected to the side wall of the guide mechanism.

[0018] Compared with the prior art, the beneficial effects of the present invention, using the above technical solution, are as follows: 1. This application achieves precise adjustment of the distance and angle between the guide mechanism and the inspection mechanism through the transmission structure of the adjusting component: rotating the adjusting screw drives the screw sleeve plate to slide axially, which in turn drives the toothed plate to mesh with the toothed groove ring at the shaft end of the bending seat, so that the two bending seats rotate relative to each other or towards each other. At the same time, the arc plate slides synchronously in the arc cylinder, which can accurately adapt to the inspection requirements of various marble slabs' bevel angles without the need to change different specifications of equipment, greatly improving the versatility of inspection. After the inspection is completed, rotating the adjusting screw in the opposite direction will cause the arc plate to retract into the arc cylinder, and the equipment will fold into a compact state. Compared with the inconvenience of transporting existing large inspection equipment, the folded equipment is easy to carry and store, especially suitable for multi-point, decentralized sampling inspection scenarios on construction sites. It solves the pain point that existing equipment is difficult to adapt to mobile sampling inspection. The integrated folding and adjusting design ensures the structural stability during inspection and also takes into account the convenience of storage when not in use.

[0019] 2. This application achieves multi-directional, full-coverage detection of marble edges through multiple elastic telescopic components arranged in a staggered manner within the frame, avoiding the problem of missing individual detection points. The piston push rod and piston cylinder of the elastic telescopic components work together to mechanically expel marking paint from the spray pipe when the caster wheel contacts the damaged area. The design of the spray pipe port being flush with the bottom of the frame ensures that the marking point corresponds perfectly to the damaged location without any offset error. Simultaneously, the distance sensor of the recording mechanism monitors the distance change between the shaft frame and the stone edge in real time. When the distance difference exceeds a preset threshold, it immediately triggers an alarm, forming a closed-loop collaboration of "detection-marking-early warning". In addition, the marking component adopts a disposable quantitative color developing cylinder and threaded connection design, which not only ensures the uniform application of marking paint, avoiding waste and pollution, but also facilitates quick replacement, further improving the continuity of detection. Compared with existing equipment, it can more accurately capture hidden damage and simultaneously complete marking and early warning, providing accurate basis for subsequent repair treatment and significantly improving the accuracy of construction quality control.

[0020] 3. Regarding guiding stability, this application utilizes a symmetrically arranged frame and an internally inclined, intersecting roller structure to ensure the equipment consistently conforms to the marble edge contour during movement, preventing deviation and jamming. The flared rubber suction cups within the external grooves of the rollers create negative pressure adsorption through expelling air, further enhancing the adhesion stability between the equipment and the stone surface. This ensures continuous detection even in uneven edge areas, unaffected by on-site vibrations or minor bumps. In terms of environmental interference resistance, the equipment eliminates the need for complex image acquisition and processing modules. Through mechanical contact detection and a simple distance sensing alarm mechanism, it completely eliminates interference from environmental factors such as lighting and background. Compared to computer vision inspection equipment, it can operate stably even in dimly lit, brightly lit, and dusty construction sites. Regarding operational safety and convenience, the automated inspection process replaces manual touch judgment, avoiding the risk of scratches from sharp edges and corners. Furthermore, the equipment's overall structure is simple, requiring no professional skills for adjustment and operation. Combined with a wireless power supply design via a battery module, it can be used for inspections at any location on the construction site, adapting to complex environments.

Detailed Implementation

[0023] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding the present invention, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0024] Reference Figures 1-7 A marble edge damage detection device includes a folding mechanism 100, a guiding mechanism 200, a marking mechanism 300, and a recording mechanism 400. The folding mechanism 100 is used to control the storage of the testing equipment, including an opening and closing frame 110 and an adjusting component 120. The opening and closing frame 110 is located between the guide mechanism 200 and the inspection mark mechanism 300, and the adjusting component 120 is located in the middle of the opening and closing frame 110. The guiding mechanism 200 is used to control the testing equipment to fit closely to the edge of the stone, and includes a frame 210 fixedly connected to the end of the opening and closing frame 110 and a roller 220 rotatably connected inside the frame 210; The inspection and marking mechanism 300 is used to mark the location of damage on the edge of the stone, including a contact 310 fixedly connected in the groove of the opening and closing frame 110 and a marking element 320 connected to the side wall of the contact 310; The recording device 400 is used to monitor and report the damage status of the stone edges.

[0025] This marble edge damage detection equipment utilizes the automated collaborative operation of four mechanisms: a folding mechanism 100, a guiding mechanism 200, an inspection marker mechanism 300, and a recording mechanism 400. This replaces traditional manual visual inspection and touch judgment, eliminating the need for personnel to check point by point. The equipment moves along the edge to complete a comprehensive inspection, simultaneously marking damage and providing alarm feedback. This significantly reduces the inspection time for a single slab, meeting the efficiency requirements of batch sampling inspections at construction sites and effectively preventing delays in the construction cycle. The precise size adaptation of the folding mechanism 100, the stable and close guidance of the guiding mechanism 200, and the staggered full-coverage inspection of the inspection marker mechanism 300 work together to avoid subjective errors and missed detections inherent in manual inspection. In particular, the elastic telescopic component 312 and piston-type... The spray structure can accurately capture hidden damage such as tiny cracks and minor chipping, with the marked points perfectly corresponding to the damage locations, providing precise positioning for subsequent processing and improving the accuracy of construction quality control. Secondly, the convenient adjustment and storage design of the folding mechanism 100 makes the equipment easy to operate when adapting to different sizes of stone, requiring no professional tools and lowering the barrier to entry. At the same time, the one-time threaded connection design of the marking component 320 facilitates quick replacement, further improving the ease of use of the equipment. Moreover, the equipment adopts a design that combines mechanical structure with simple electrical control, eliminating the need for a complex image processing system. It has strong resistance to environmental interference such as changing lighting and cluttered backgrounds at the construction site, and can be moved and inspected at any location on the construction site. It is easy to carry and transport in construction sites with dense stacks of slabs, adapting to complex construction sampling and inspection environments.

[0026] Reference Figure 1 and Figure 3 The opening and closing frame 110 includes an arc cylinder 111 fixedly connected to the middle of the adjusting member 120. Two arc plates 112 are symmetrically slidably connected inside the arc cylinder 111. One end of the arc plate 112 is fixedly connected to a bending seat 113. The two bending seats 113 are symmetrically arranged and are respectively connected to the adjusting member 120 and the corresponding mechanism. The adjusting component 120 includes a shaft frame 121 sleeved in the middle of the arc cylinder 111 and rotatably engaged with the bending seat 113. An adjusting screw 122 is rotatably connected in the middle of the shaft frame 121. The external thread of the adjusting screw 122 is adapted to a screw sleeve plate 123. The screw sleeve plate 123 is sleeved on the outside of the shaft frame 121 and slidably engaged with the shaft frame 121. Two toothed plates 124 are arranged symmetrically in a staggered manner on the screw sleeve plate 123. A toothed ring 125 is engaged on one side of the toothed plate 124. The toothed ring 125 is sleeved on the shaft end of the bending seat 113.

[0027] This marble edge damage detection device drives the screw sleeve plate 123 to slide axially through the rotation of the adjusting screw 122 of the adjusting component 120, which in turn drives the toothed plate 124 to mesh with the toothed groove ring 125 at the shaft end of the bending seat 113, thereby realizing the relative or opposite rotation of the two bending seats 113. At the same time, the arc plate 112 slides synchronously in the arc cylinder 111, realizing the precise adjustment of the distance and angle between the guide mechanism 200 and the inspection mark mechanism 300 to adapt to the detection of the bevel angle of various marble slabs. After the detection is completed, rotating the adjusting screw in the opposite direction can retract the arc plate 112 into the arc cylinder 111, and the device is folded into a compact state for easy carrying and storage.

[0028] Reference Figure 2 and Figure 4 The frames 210 are symmetrically arranged at the ends of the opening and closing frame 110, and the number of rollers 220 rotatably connected in the two frames 210 is different and they are arranged in an inclined cross structure. The roller 220 has multiple grooves along the annular structure on its outer side, and each groove is fixedly connected to a horn-shaped rubber suction cup.

[0029] This marble edge damage detection device uses inclined, cross-arranged rollers 220 inside the frame 210 to ensure that the device always conforms to the edge contour of the marble during movement, avoiding deviation or jamming. The trumpet-shaped rubber suction cups outside the rollers 220 can form negative pressure adsorption by squeezing out the internal gas when the device is in contact with the edge, further improving the adhesion stability between the device and the stone surface. This ensures that the inspection marker can accurately align with the edge area during the inspection process, providing a basic guarantee for the accuracy of damage detection.

[0030] Reference Figure 5 and Figure 6 The contact element 310 includes a sleeve frame 311 fixedly connected to the bending seat 113. Multiple elastic telescopic elements 312 are fixedly connected inside the sleeve frame 311, and the multiple elastic telescopic elements 312 are arranged in a staggered structure.

[0031] This marble edge damage detection device, through multiple elastic telescopic components 312 staggered within the frame 311, can achieve multi-directional coverage detection of the marble edge, avoiding the omission of minor damage due to a single detection point; the elastic buffering characteristics of the elastic telescopic components 312 allow the casters to always slide in close contact with the edge, and even if there are irregular protrusions or depressions on the edge, they can be adaptively adjusted through extension and retraction to ensure the continuity and integrity of the detection process.

[0032] Reference Figure 5 and Figure 7The elastic telescopic component 312 includes a piston push rod 317 with universal wheels, a piston cylinder 318 sleeved outside the piston push rod 317, and a spring component 319 for constraining the two to achieve elastic telescopic movement. The piston cylinder 318 has a symmetrical arrangement of one-way inlet valves 313 and one-way outlet valves 314. Multiple one-way inlet valves 313 are fixedly connected to each other by a manifold 315 through a hose. The manifold 315 is fixedly connected to the side wall of the sleeve frame 311. A spray pipe 316 is fixedly connected to the outside of the one-way outlet valve 314. The port of the spray pipe 316 is flush with the bottom of the frame 210.

[0033] This marble edge damage detection device utilizes the piston push rod 317 of the elastic telescopic component 312 in conjunction with the piston cylinder 318. During the detection process, when the universal wheel at the end of the piston push rod 317 encounters the damaged area, the piston push rod 317 is compressed and moves axially along the piston cylinder 318. Under the reset action of the compression spring, the marking paint inside the piston cylinder 318 is squeezed, causing the paint to be sprayed out from the spray pipe 316 through the one-way drain valve 314, accurately marking the damage location. The design of the spray pipe 316 port being flush with the bottom of the frame 210 ensures that the marking point corresponds perfectly with the damage location, avoiding marking offset and preventing obstruction of its storage. When the device moves to a flat area, the spring is compressed, the piston push rod 317 returns to its original position, and a negative pressure is formed inside the piston cylinder 318. The paint inside the marking component 320 is drawn from the manifold 315 through the one-way inlet valve 313 to replenish the marking, preparing for the next damage marking.

[0034] Reference Figure 6 The marking component 320 is a quantitative color developing cylinder for filling marking paint. The quantitative color developing cylinder is a disposable packaging structure and is threadedly connected to the manifold connector 315.

[0035] This marble edge damage detection device uses disposable quantitative colorimetric cylinders as markers, along with threaded connections, to enable quick disassembly and replacement of the markers 320. This makes operation convenient and avoids paint leakage and contamination. The quantitative design ensures that the amount of paint used for each marking is uniform, the markings are clear and not wasteful, and the disposable structure prevents the paint from deteriorating over a long period of time, thus improving the reliability and convenience of the equipment.

[0036] Reference Figure 2 The recording mechanism 400 includes a distance sensor fixedly connected to the side wall of the guide mechanism 200, a battery module, and a speaker electrically connected between the distance sensor and the battery module.

[0037] This marble edge damage detection device monitors the distance between the frame and the stone edge in real time using a distance sensor. A normal edge distance threshold is preset. When the detected distance difference exceeds the threshold, it indicates that damage has caused a change in the fit between the device and the edge. The sensor immediately sends a signal to trigger the speaker to sound an alarm, reminding the inspection personnel to pay attention to the location of the damage in real time. The battery module provides a stable power supply to the sensor and speaker, ensuring that the device can work normally in construction sites without external power, thus improving the device's environmental adaptability.

[0038] The specific steps of its working principle are as follows: Equipment pretreatment: First, connect the marker 320, i.e., the disposable quantitative color developing cylinder, to the manifold 315 via thread to ensure a sealed connection and prevent paint leakage; then check the battery module power of the recording mechanism 400 to ensure sufficient power supply; then, adjust the detection threshold of the distance sensor according to the normal flatness parameters of the edge of the marble slab to be tested to ensure that the speaker can respond in time and trigger an alarm when the distance difference exceeds the threshold. Size adaptation adjustment: Based on the thickness and edge contour dimensions of the marble slab to be tested, rotate the adjusting screw 122 of the adjusting component 120; since the threaded sleeve plate 123 is threadedly matched with the adjusting screw 122, and the screw sleeve plate 123 is slidably fitted with the shaft bracket 121, the rotation of the adjusting screw 122 will drive the screw sleeve plate 123 to move smoothly along the axial direction of the shaft bracket 121; the two toothed plates 124 on the screw sleeve plate 123 move synchronously, meshing with the toothed ring 125 fitted on the shaft end of the bending seat 113, thereby driving the two bending seats 113 to move in tandem. The two plates rotate in opposite directions; at the same time, the arc plate 112 slides synchronously in the arc cylinder 111 until the distance and angle between the guide mechanism 200 and the inspection mechanism 300 are completely adapted to the marble edge size; during this process, the two spring pieces 319 that were originally mutually restrained are released from restraint as the angle of the bending seat 113 opens, and under their own elastic action, they are limited to extend and open, pushing the piston rod 317 to the limit position, and venting the gas in the piston cylinder 318 near the end of the plate to be inspected, preparing for the subsequent paint suction; Fitting and positioning: The debugged equipment is smoothly fitted to the edge of the marble slab, so that the rollers 220 arranged at an angle and cross inside the frame 210 of the guide mechanism 200 are in close contact with the edge; the horn-shaped rubber suction cups in the grooves outside the rollers 220 are squeezed, expelling the internal gas and forming a negative pressure, which firmly adheres to the marble surface, ensuring that the equipment stays close to the edge and does not shift during movement; at the same time, the spring 319, which has been stretched to its limit, is elastically contracted by the pressure of the stone when the equipment is fitted to the stone surface, and the piston push rod 317 moves into the piston cylinder 318, creating a negative pressure inside the piston cylinder 318. The marking paint in the quantitative color developing cylinder of the marking component 320 is drawn in through the one-way liquid inlet valve 313, and the paint enters the piston cylinder 318 for storage through the manifold 315 and the hose; Mobile Detection and Damage Handling: The inspector pushes the equipment along the marble edge at a constant speed. During this process, the casters of the multiple staggered elastic telescopic components 312 within the 300-frame 311 of the inspection mechanism always slide close to the edge, achieving all-around coverage inspection. When the marble edge has cracks, chipped edges, or missing corners, the piston push rod 317 of the elastic telescopic component 312 is subjected to pressure or changes in support force at the damaged area, causing abnormal movement along the axial direction of the piston cylinder 318, further compressing the spring component 319. The movement of the piston push rod 317 squeezes the marking paint inside the piston cylinder 318, allowing the paint to overcome the resistance of the one-way drain valve 314 and be precisely sprayed onto the damaged location through the spray pipe 316, achieving real-time damage marking. Simultaneously, the distance sensor of the recording mechanism 400 monitors the distance difference between the shaft frame 121 and the stone edge in real time. When the distance difference exceeds a preset threshold, the sensor immediately sends an electrical signal to the control module integrated in the battery module. The control module triggers a speaker to sound an alarm, reminding the inspector of the damage, facilitating timely recording and handling. Paint replenishment and cycle detection: When the elastic telescopic component 312 moves to a flat area on the edge of the marble, the spring component 319 loses the compression of the damaged area and pushes the piston rod 317 back to its initial position under its own elastic restoring force. During the return of the piston rod 317, a negative pressure is formed again in the piston cylinder 318, and the one-way liquid inlet valve 313 automatically opens. The marking paint in the marking component 320 is replenished into the piston cylinder 318 through the manifold 315 and the hose, completing the paint replenishment and preparing for the next damage marking, ensuring that the equipment can continuously carry out detection operations. Equipment Storage: After the testing of a single marble slab is completed, the adjusting screw 122 is rotated in the opposite direction. Through the meshing transmission between the toothed plate 124 and the toothed ring 125, the two bending seats 113 are driven to rotate in opposite directions. The arc plate 112 gradually retracts into the arc cylinder 111, making the equipment fold into a compact state. Then, the used disposable quantitative color developing cylinder is disassembled, and the port of the spray pipe 316 is simply cleaned before the equipment can be stored and carried to the next testing location. When the equipment is removed from the stone surface, the spring 319 in contact with the stone extends and opens again. Under the action of the spring return force, the piston push rod 317 is pushed to the limit to discharge the residual marking paint in the piston cylinder 318, avoiding the paint from staying for a long time and causing pipeline blockage.
