Description

Technical Field

[0001] This invention relates to the field of ALC board testing technology, specifically an ALC board flatness testing device. Background Technology

[0002] ALC panels, as a lightweight building material with excellent thermal insulation and fire resistance, have been widely used in prefabricated and green building construction in recent years. The surface flatness of ALC panels after installation directly affects the quality of subsequent wall plastering and decorative layer construction, thus impacting the overall aesthetics and safety of the building. Substandard flatness can easily lead to cracking and peeling of the finishing materials, and even affect the structural sealing and durability. Therefore, flatness testing of ALC panels is an indispensable quality control step in the building construction process and has significant engineering importance.

[0003] Currently, the industry's conventional methods for inspecting the flatness of ALC panels mostly rely on manual operation. Common practices include using tools such as straightedges, feeler gauges, and laser rangefinders, with technicians manually measuring each point after the ALC panels are installed. While these methods use simple tools and are low-cost, they suffer from low inspection efficiency, high labor intensity, and long processing times, making them unsuitable for the large-scale, high-speed operations required in modern construction. Therefore, there is an urgent need to develop a device suitable for batch inspection of ALC panels. Summary of the Invention

[0004] This invention provides an ALC board flatness detection device, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: An ALC plate flatness detection device includes a support frame, with guide belts on both sides of the support frame. An ALC plate is placed on the guide belts and moves synchronously with them. The middle of the guide belts is raised. The device also includes a lifting mechanism and a detection mechanism. The lifting mechanism is located in the middle of the support frame and is used to lift the ALC plate to a position higher than the guide belts. The detection mechanism is located on the upper and lower sides of the ALC plate. After the ALC plate is lifted by the lifting mechanism, the two detection mechanisms respectively perform flatness detection on both sides of the ALC plate. Each detection mechanism has at least three contact points with the ALC plate.

[0010] As a preferred embodiment of the present invention, the detection mechanism includes fixed disks disposed on both sides of the ALC plate, with extension plates fixedly connected to the outer side of the fixed disks. The number of extension plates is greater than or equal to three. The extension plates are symmetrically arranged with respect to the center circumference of the fixed disks. A probe is disposed at the end of the extension plate away from the fixed disks. The probe is disposed on the side of the extension plate close to the ALC plate. An angle sensor for detecting the tilt angle of the fixed disks is disposed in the middle of the fixed disks.

[0011] In a preferred embodiment of the present invention, a bottom beam is provided on the side of the lifting plate away from the ground. A sliding rod is slidably connected to the middle of the bottom beam. A buffer spring is sleeved on the outside of the sliding rod to restrict its movement. The end of the sliding rod is connected to a fixed plate via a rotating ball joint. Lifting assemblies for adjusting the distance between the bottom beam and the lifting plate are provided on both sides of the lifting plate. When the two support rods on both sides of the lifting plate rotate close to each other, the lifting assembly pushes the bottom beam to move towards the side away from the lifting plate. The lifting assembly includes lifting columns slidably connected to both sides of the lifting plate. The end of the lifting column away from the ground is fixedly connected to the bottom beam. A limiting ring is engaged on the lifting column to limit its lowest position. A suspension plate is provided on the side of the lifting plate near the ground. A sliding rod that cooperates with the support rod is slidably connected to the end of the suspension plate. A top rod is rotatably connected to the end of the sliding rod near the center of the lifting plate.

[0030] 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.

[0031] In one embodiment, see Figure 1 , Figure 2 and Figure 5An ALC plate flatness detection device includes a support frame 1, which is welded from square tubes. The bottom of the support frame 1 is formed by two sets of square tubes welded into a U-shape. A trapezoidal structure is set in the middle of the front and rear sides of the support frame 1. Annular guide belts 2 are set on both the front and rear sides of the support frame 1. The guide belts 2 are trapezoidal in shape, and their upper ends are higher than the upper end of the support frame 1. The two guide belts 2 rotate synchronously in the same direction. After the front and rear ends of the ALC plate 5 are placed on the guide belts 2, the ALC plate 5 will move with the guide belts 2. The device also includes a lifting mechanism 3 and a detection mechanism 4. The lifting mechanism 3 is located in the middle of the support frame 1. When the ALC plate 5 moves directly above the support frame 1, the lifting mechanism 3 will... The ALC plate 5 is lifted up, at which point the ALC plate 5 is disengaged from the guide belt 2. When the lifting mechanism 3 moves downward, the front and rear ends of the ALC plate 5 will fall back onto the guide belt 2. The lifting mechanism 3 realizes the up and down movement of the ALC plate 5. The detection mechanism 4 is set on the upper and lower sides of the ALC plate 5. When the lifting mechanism 3 drives the ALC plate 5 to the highest point, the upper and lower detection mechanisms 4 will contact the upper and lower sides of the ALC plate 5 respectively. According to the requirements of the detection standard, the flatness detection requires more than three measurement points for each wall or every 20 square meters. Since this application needs to detect the tilt angle of the entire surface, the detection points of one detection mechanism 4 are more than three. The effect of three-point detection is shown in the attached figure.

[0032] In one instance of this embodiment, please refer to Figure 3 and Figure 4 Guide pulleys 7 are installed at both ends of the support frame 1 and on the plane above the support frame 1. In particular, multiple sets of guide pulleys 7 are installed above the support frame 1. The outer side of the guide pulleys 7 is connected to the guide belt 2. On the one hand, the guide pulleys 7 have a guiding effect, driving the guide belt 2 to rotate. On the other hand, since multiple sets of guide pulleys 7 are installed above the support frame 1, the guide pulleys 7 also have a supporting effect, so that the ALC plate 5 can be placed flat on the guide belt 2 above. Protective side plates 6 are installed on the left and right sides of the support frame 1. The upper part of the protective side plates 6 is inclined, and the left and right sides of the guide belt 2 can just fall on the protective side plates 6. The protective side plates 6 can support the guide belt 2. That is to say, when the ALC plate 5 is placed on the left and right sides of the guide belt 2, the protective side plates 6 can provide a certain support effect. Furthermore, a first drive motor 11 is installed at the middle of the right end of the support frame 1. The first drive motor 11 is connected to the middle of the drive shaft 12, which is arranged in a front-to-back orientation, through a belt drive device 10. The front and rear ends of the drive shaft 12 are fixedly connected to two guide pulleys 7 at the right end of the support frame 1. Therefore, the first drive motor 11 realizes the rotation of the drive shaft 12 through belt drive. The drive shaft 12 drives the two guide pulleys 7 to rotate, thereby making the two guide belts 2 rotate synchronously and in the same direction.

[0033] In one instance of this embodiment, please refer to Figure 3 and Figure 4 To allow the ALC plate 5 to be better placed on the guide belt 2, vertical auxiliary support plates 8 are provided at both ends of the support frame 1. The upper end of the auxiliary support plate 8 is rotatably connected to the auxiliary support rollers 9, which are arranged in a front-to-back direction. The upper end of the auxiliary support rollers 9 is higher than the guide belt 2. Therefore, during use, the ALC plate 5 can be hoisted above the auxiliary support rollers 9 using hoisting equipment. The auxiliary support rollers 9 then lift the ALC plate 5 and push it towards the guide belt 2. When one end of the ALC plate 5 contacts the guide belt 2, the guide belt 2 will move the ALC plate 5, thus achieving the feeding effect. On the other hand, after the ALC plate 5 has completed the inspection, the guide belt 2 will push the ALC plate 5 towards the auxiliary support roller 9. One end of the ALC plate 5 will be lifted by the auxiliary support roller 9. At this time, the ALC plate 5 can be fixed by the hoisting equipment. After the initial fixing is completed, the ALC plate 5 can be completely separated from the guide belt 2 and fall on the auxiliary support roller 9. At this time, the horizontal state of the ALC plate 5 can be adjusted so that the hoisting equipment can maintain a stable transfer of the ALC plate 5 that has completed the inspection.

[0034] In one instance of this embodiment, please refer to Figure 3 , Figure 6 and Figure 7The lifting mechanism 3 includes crossbeams 13 arranged on the left and right sides of the support frame 1. The crossbeams 13, arranged front and back, are fixedly connected to the inclined sides of the left and right sides of the support frame 1 by bolts or welding. A horizontal placement plate 14 is arranged above the crossbeams 13. The left and right ends of the placement plate 14 are fixedly connected to the middle of the crossbeams 13. Horizontal sliding plates 16 are arranged on the left and right sides of the placement plate 14. The two horizontal sliding plates 16 can move left and right above the placement plate 14, and the two horizontal sliding plates 16 move towards each other synchronously or move away from each other synchronously. The lower ends of the support rods 21 are rotatably connected to the front and back sides of the horizontal sliding plates 21. The lower end of 1 is rotatably connected to the side of the horizontal sliding plate 16 near the center of the horizontal plate 14 via a hinge device. The upper end of the support rod 21 is inclined toward the center of the horizontal plate 14, and the upper end of the support rod 21 is rotatably connected to the lower surface of the lifting plate 22. Four support rods 21 are provided below the lifting plate 22, with the support rods 21 on the left and right sides arranged symmetrically. The lifting plate 22 and the horizontal plate 14 are both in a horizontal state. When the two horizontal sliding plates 16 move closer to each other, the horizontal sliding plates 16 push the lifting plate 22 upward through the support rods 21. When the two horizontal sliding plates 16 move apart, the lifting plate 22 moves downward, thereby realizing the height adjustment of the lifting plate 22. Furthermore, top plates 23 are provided at both ends of the upper surface of the lifting plate 22. The top plates 23 are vertically arranged, and rubber is provided on the upper surface of the top plates 23. When the lifting plate 22 moves upward, the upper surface of the top plates 23 will contact the lower surface of the ALC plate 5, thereby pushing the ALC plate 5 to move horizontally upward through the top plates 23. Since the rubber is provided on the upper surface of the top plates 23, on the one hand, it can increase the friction between the top plates 23 and the ALC plate 5, so that the top plates 23 can drive the ALC plate 5 to move up and down more stably. On the other hand, the rubber can prevent the top plates 23 from scratching the ALC plate 5.

[0035] In one instance of this embodiment, please refer to Figures 6-10Fixed seats are provided at the four corners of the horizontal plate 14, and the fixed seats are fixedly connected to the left and right ends of the guide rods 15. Therefore, guide rods 15 are provided on both the front and rear sides of the upper surface of the horizontal plate 14. The front and rear ends of the transverse plate 16 are slidably connected to the guide rods 15, which facilitates the stable transverse movement of the transverse plate 16 above the horizontal plate 14. In addition, a spacing adjustment component 26 is provided in the middle of the horizontal plate 14. The spacing adjustment component 26 can adjust the spacing between the two transverse plates 16, that is, adjust the height of the lifting plate 22. The spacing adjustment assembly 26 includes a motor mounting plate 17 disposed at the right end of the placement horizontal plate 14. A second drive motor 18 is disposed above the motor mounting plate 17. The output shaft of the second drive motor 18 is fixedly connected to the right end of the drive rod 19 which is oriented left and right. The left and right ends of the drive rod 19 are connected to the placement horizontal plate 14 through bearing seats. Screws 20 are disposed on the left and right sides of the drive rod 19. The threads of the two screws 20 are opposite. The screws 20 are threadedly connected to the middle of the transverse plate 16. Therefore, when the second drive motor 18 drives the drive rod 19 to rotate, the two screws 20 respectively drive the two transverse plates 16 to move closer to each other or further away from each other, thereby achieving the effect of driving the lifting plate 22 to move up and down.

[0036] In one instance of this embodiment, please refer to Figure 10 The detection mechanism 4 includes fixed disks 36 disposed on the upper and lower sides of the ALC plate 5. A horizontally arranged protruding plate 37 is fixedly connected to the outer extension of the fixed disk 36. There are three or more protruding plates 37, and they are symmetrically arranged with respect to the center circumference of the fixed disk 36, ensuring that the center of gravity of the entire detection mechanism 4 is located at the center of the fixed disk 36, which helps the detection mechanism 4 maintain a horizontal state. A probe 38 is vertically arranged at the end of the protruding plate 37 away from the fixed disk 36. The probe 38 is vertically arranged on the side of the protruding plate 37 closest to the ALC plate 5. The end of the probe 38 is provided with a rotating ball that cooperates with the ALC plate 5, so that after the end of the probe 38 presses against the ALC plate 5, the probe 38 can move laterally along the surface of the ALC plate 5. When the three probes 38 of the detection mechanism 4 contact the surface of the ALC plate 5, the horizontal angle of the detection mechanism 4 changes. At this time, the probes 38 will move laterally along the surface of the ALC plate 5 until all three probes 38 simultaneously press against the ALC plate 5, at which point the detection mechanism 4 will stop deflecting. An angle sensor 35 is set at the center of the fixed plate 36. The angle sensor 35 can identify the tilt angle of the entire fixed plate 36 in real time, that is, the tilt angle of the plane formed by the ends of the three probes 38, which is the flatness of the ALC plate 5.

[0037] In one instance of this embodiment, please refer to Figures 6-10A bottom beam 25 facing forward and backward is set directly above the horizontal plate 14. A vertically set sliding rod 32 is slidably connected to the middle of the bottom beam 25. The lower end of the sliding rod 32 is connected to the center of the fixed plate 36 through a rotating ball head 34. That is to say, the fixed plate 36 can freely deflect around the sliding rod 32. Furthermore, a buffer spring 33 that cooperates with the bottom beam 25 is sleeved on the outside of the sliding rod 32. When the probe 38 presses against the ALC plate 5, the buffer spring 33 will undergo adaptive deformation, ensuring that the three probes 38 can contact the ALC plate 5 simultaneously. Furthermore, lifting components 24 are provided on the front and rear sides of the lifting plate 22. The lifting components 24 can push the bottom beam 25 upward, and the support rod 21 and the bottom beam 25 are linked through the lifting components 24. When the two support rods 21 on the left and right sides move closer to each other, the support rods 21 will push the bottom beam 25 upward through the lifting components 24. That is to say, when the lifting plate 22 lifts the ALC plate 5 upward, the bottom beam 25 will also move upward, so that the detection mechanism 4 installed on the bottom beam 25 contacts the lower surface of the ALC plate 5. When the lifting plate 22 moves downward, the bottom beam 25 will also drive the detection mechanism 4 to move downward and disengage from the ALC plate 5, without affecting the normal lateral movement of the ALC plate 5.

[0038] In one instance of this embodiment, please refer to Figures 6-10 The lifting assembly 24 includes a lifting column 30 slidably connected to the front and rear ends of the lifting plate 22. The upper end of the lifting column 30 is fixedly connected to the front and rear ends of the lower surface of the bottom beam 25. A limiting ring 31 is snapped into the upper part of the lifting column 30. Two semi-circular limiting rings 31 are snapped into the upper part of the lifting column 30 by bolts. When the lifting column 30 moves downward, the limiting rings 31 will interfere with the lifting plate 22, thereby limiting the maximum descent distance of the lifting column 30. Furthermore, suspension plates 28 are fixedly connected to the lifting plate 22 on both the left and right sides of the lifting column 30. The suspension plates 28 are vertically installed on the lower surface of the lifting plate 22. The lower end of the suspension plates 28 is slidably connected to sliding rods 27 oriented left and right. The end of the sliding rod 27 near the center of the lifting plate 22 is rotatably connected to the lower end of the top rod 29. The upper end of the top rod 29 is rotatably connected to the lower end of the lifting column 30. When the two support rods 21 on the left and right sides rotate a certain angle and approach each other, the side of the support rod 21 will contact the end of the sliding rod 27 away from the center of the lifting plate 22. At this time, the two support rods 21 will push the two sliding rods 27 to move closer to each other. The two sliding rods 27 push the lifting column 30 upward through the top rod 29, thereby causing the detection mechanism 4 below to move upward and contact the ALC plate 5. When the two support rods 21 rotate away from each other, the two sliding rods 27 move away from each other. At this time, the detection mechanism 4 below will move downward.

[0039] In one instance of this embodiment, please refer to Figure 11 and Figure 12 A back support 39 is provided on the rear side of the support frame 1. The back support 39 is vertically set, and its lower end and middle part are fixed to the upper and lower sides of the support frame 1, respectively. A U-shaped channel steel is sleeved under the support frame 1 and connected to the back support 39 to improve the stability of the back support 39. A suspension beam 40 with a front-to-back orientation is provided on the upper front side of the back support 39. The suspension beam 40 is fixed to the back support 39 by welding and L-shaped connectors. In order to improve the structural stability of the back support 39 and the suspension beam 40, a vertical plate is welded to the middle of the back support 39 and the suspension beam 40. Vertical sliding rods 32 are slidably connected to the left and right sides of the front end of the suspension beam 40. The lower end of the sliding rod 32 is fixedly connected to the top beam 41. A buffer spring 33 is provided between the top beam 41 and the suspension beam 40. The buffer spring 33 is sleeved on the outside of the sliding rod 32 and is also used to provide buffering when the probe 38 contacts the ALC plate 5. The fixed plate 36 of the detection mechanism 4 is connected to the middle of the lower surface of the top beam 41 by rotating ball head 34, so that the detection mechanism 4 above can also be freely deflected relative to the lower surface of the top beam 41.

[0040] In this embodiment, during implementation, the ALC plate 5 is moved to the auxiliary support roller 9 on the right side by a hoisting device, and then pushed to the left so that the left end of the ALC plate 5 rests on the right side of the guide belt 2. At this time, the connecting rope between the hoisting device and the ALC plate 5 is released, and the first drive motor 11 is started. The guide belt 2 drives the ALC plate 5 to move to the left. When the ALC plate 5 moves directly above the support frame 1, the guide belt 2 is stopped. At this time, the second drive motor 18 is started, and the lifting plate 22 moves upward. The lifting plate 22 drives the ALC plate 5 to move horizontally upward through the top plates 23 on both sides. During the movement, the lower lifting component 24 pushes the lower detection mechanism 4 to move upward and contact the lower surface of the ALC plate 5. Simultaneously, after the ALC plate 5 moves upward, its upper surface will contact the detection mechanism 4 above. The probes 38 of the detection mechanisms 4 on both sides will press against the upper and lower sides of the ALC plate 5. The fixed plate 36 will deflect adaptively, and the angle sensor 35 will obtain the tilt angle of the upper and lower surfaces of the ALC plate 5 in real time, thereby obtaining the flatness detection data. After the detection is completed, the lifting plate 22 moves downward, the two detection mechanisms 4 are separated from the ALC plate 5, and the ALC plate 5 falls back onto the guide belt 2. The guide belt 2 moves the ALC plate 5 to the auxiliary support roller 9 on the left. At this time, the ALC plate 5 that has completed the detection is transferred away again by the hoisting equipment, and the undetected ALC plate 5 is hoisted again.

[0041] This invention provides an ALC board flatness detection device. The lifting mechanism 3 smoothly lifts the ALC board 5, allowing it to simultaneously contact two sets of detection mechanisms 4, achieving synchronous detection of the upper and lower surfaces. This significantly improves detection efficiency and data integrity. After detection, the board automatically falls back to the guide belt 2 and is transported out of the station. Combined with hoisting equipment, this enables rapid transfer of boards to be inspected and those already inspected, greatly adapting to the continuous detection needs of large batches of ALC boards 5. Specifically, by setting a lifting component 24 on the lifting plate 22, which collaboratively pushes the lower detection mechanism 4 upwards during the lifting process, the device achieves linkage control between lifting and detection positioning. All detection preparations can be completed with a single drive, greatly simplifying the operation process and improving the overall reliability, practicality, and automation level of the system.

[0042] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
