Description

Technical Field

[0001] This invention relates to the field of ALC panel testing technology, specifically to a testing device for preventing cracking of prestressed joints in prefabricated building ALC panels. Background Technology

[0002] With the rapid development of the prefabricated building industry, ALC panels, with their numerous advantages such as lightweight, high strength, thermal insulation, sound insulation, and environmental friendliness, are widely used in the construction of wall and ceiling structures in prefabricated buildings. During the installation of ALC panels, the quality of the prestressed connection at the joints directly determines the integrity and stability of the entire enclosure structure. If the prestressed connection at the joints is not firm or there is stress concentration, cracking is very likely to occur during use, thus affecting the building's waterproofing and thermal insulation performance, and even threatening the building's structural safety.

[0003] Currently, existing detection devices for preventing cracking in prestressed connections of ALC panel joints suffer from a significant limitation: they are limited to a single detection scenario and cannot adequately meet the inspection needs of ALC panels installed on walls and ceilings in prefabricated buildings, which present different orientations. Specifically, traditional detection devices are mostly fixed structures or can only achieve height adjustment in one direction, limiting their detection capabilities to vertically installed ALC panel joints. When inspecting ALC panel joints on ceilings, additional scaffolding, lifting platforms, and other auxiliary facilities are often required, necessitating operators to work at heights. This not only results in cumbersome operations and low detection efficiency but also poses significant safety hazards associated with working at heights. Summary of the Invention

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a detection device for crack prevention in prestressed connections of ALC panels in prefabricated buildings. This device solves the problem that existing devices have limited detection scenarios and are difficult to adapt to the detection needs of ALC panels with different postures in prefabricated buildings, namely, ALC panels erected on walls and ALC panels on ceilings.

[0005] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: a detection device for preventing cracking of prestressed joints in prefabricated ALC panels, comprising a moving component, a driving component fixedly mounted on the moving component, a lifting component movably mounted on the driving component, a flipping component rotatably mounted on the lifting component, and a detection mechanism fixedly mounted on the flipping component.

[0006] According to one embodiment of the present invention, the drive assembly includes a support cabinet, a drive motor fixedly disposed in the support cabinet, a threaded shaft interconnected with the output end of the drive motor, two sets of toothed plates respectively fixedly disposed at both ends of the support cabinet, and limiting grooves formed on both sides of the support cabinet.

[0007] According to one embodiment of the present invention, the lifting assembly includes a lifting block, sliders respectively fixedly disposed on both sides of the lifting block, threaded holes formed in the lifting block, a first fixing frame fixedly disposed on the lifting block, and a locking part fixedly disposed on the lifting block; the limiting groove is slidably engaged with the slider.

[0008] According to one embodiment of the present invention, the locking part includes a hydraulic push rod fixedly disposed on the inner wall of the lifting block, a locking block fixedly disposed on the output end of the hydraulic push rod, a locking groove that slides with the locking block, a pawl that slides with the locking block through the locking groove, a fixing seat fixedly disposed on both sides of the pawl, a locking post fixedly disposed on the fixing seat, a second fixing frame that slides with the locking post, and a spring fixedly disposed on the second fixing frame.

[0009] According to one embodiment of the present invention, the second fixing frame is fixedly connected to the outer wall of the support cabinet, and the end of the spring away from the second fixing frame is fixedly connected to the fixing base.

[0010] According to one embodiment of the present invention, the flipping assembly includes a flipping shaft rotatably disposed on the first fixed frame, a ratchet fixedly disposed on the flipping shaft, gears respectively fixedly disposed at both ends of the flipping shaft, and flipping frames respectively symmetrically disposed on the flipping shaft.

[0011] According to one embodiment of the present invention, when the pawl and the ratchet gear are engaged, the flipping shaft can only rotate clockwise within the first fixed frame; when the gear moves vertically to the position of the toothed plate, the toothed plate and the gear mesh with each other.

[0012] According to one embodiment of the present invention, the drive assembly further includes a limiting post fixedly disposed on the support cabinet; a limiting hole is provided on the flip frame, and the limiting hole is inserted into the limiting post.

[0013] According to one embodiment of the present invention, the detection mechanism is fixedly mounted on the flipping frame.

[0014] According to one embodiment of the present invention, the moving component includes a platform fixedly disposed at the bottom of the support cabinet, wheels disposed at the bottom of the platform, and a push handle fixedly disposed on the platform.

[0015] (III) Beneficial Effects Compared with the prior art, the present invention provides a detection device for crack prevention of prestressed connection of precast ALC panel joints in prefabricated buildings, which has the following beneficial effects: 1. This prestressed connection crack prevention detection device for prefabricated ALC panel joints in prefabricated buildings effectively achieves flexible switching between two detection states: vertical ALC panel joints and ceiling ALC panel joints, through the coordinated structure of the drive component, lifting component, and flipping component. This significantly expands the device's detection application range, improves detection convenience and efficiency, and effectively solves the problem of limited detection scenarios for traditional detection devices.

[0016] 2. This prestressed connection crack prevention detection device for ALC panel joints in prefabricated buildings, through its structural design of a locking part and a ratchet gear working in tandem, prevents the flipping component from reversing, enhancing the device's detection stability in two detection states and ensuring accurate and reliable detection data. When detecting joints in vertical ALC panels, the pawl of the locking part and the ratchet gear of the flipping component are always engaged, and with the help of the limiting structure, the component is prevented from accidentally flipping, providing a stable posture for the detection mechanism. When detecting joints in ceiling ALC panels, during the flipping of the component, the pawl intermittently engages with the ratchet gear under the spring force of the locking part, without affecting the smooth flipping, and can also temporarily limit the movement to avoid structural damage.

[0017] 3. The prestressed connection crack prevention detection device for ALC panel joints in this prefabricated building utilizes a structural design with limiting posts and holes to further enhance the device's structural stability during the detection process. This provides a reliable support foundation for the detection mechanism and effectively avoids detection deviations. When detecting vertically installed ALC panel joints, the limiting posts on the drive assembly are inserted into the limiting holes of the flipping frame of the flipping assembly, forming a double limiting structure. This, along with the locking part and ratchet, prevents the flipping assembly from automatically flipping or shaking during lifting or detection, ensuring that the detection probe is aligned with the joint to be detected and guaranteeing the continuity and accuracy of the detection.

[0020] 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.

[0021] Example 1 Please see Figure 1 - Figure 7 This is the first embodiment of the present invention. This embodiment provides a detection device for preventing cracking of prestressed joints of prefabricated building ALC panels, specifically including: a moving component 1, a driving component 2 fixedly mounted on the moving component 1, a lifting component 3 movably mounted on the driving component 2, a flipping component 4 rotatably mounted on the lifting component 3, and a detection mechanism 5 fixedly mounted on the flipping component 4.

[0022] It should be noted that the moving component 1 is used to move the device to the joint of the ALC panel for crack prevention detection; the driving component 2 is used to provide motion power for the lifting component 3 and the tilting component 4; when the lifting component 3 reciprocates vertically on the driving component 2, the detection mechanism 5 performs crack prevention detection on the vertically connected ALC panel; when the lifting component 3 moves to the top of the driving component 2, the tilting component 4 rotates ninety degrees around the lifting component 3, and the top of the tilting component 4 and the top of the driving component 2 fit together, so that the detection mechanism 5 can perform crack prevention detection on the ALC panel on the ceiling.

[0023] Testing agency 5 employs a mechanical stress detector, a technology already in use. This detector features high precision and stability, enabling it to accurately measure minute displacement changes at the joints of ALC panels. By precisely capturing these displacement changes, it is possible to effectively determine whether there is a risk of cracking at the joints of ALC panels, providing a reliable guarantee for the quality and safety of prefabricated buildings.

[0024] Furthermore, the drive assembly 2 includes a support cabinet 21, a drive motor 22 fixedly disposed in the support cabinet 21, a threaded shaft 23 connected to the output end of the drive motor 22, two sets of toothed plates 24 respectively fixedly disposed at both ends of the support cabinet 21, and limiting grooves 25 opened on both sides of the support cabinet 21.

[0025] Furthermore, the lifting assembly 3 includes a lifting block 31, sliders 32 respectively fixedly disposed on both sides of the lifting block 31, threaded holes 33 opened in the lifting block 31, a first fixing frame 34 fixedly disposed on the lifting block 31, and a locking part 35 fixedly disposed on the lifting block 31; the limiting groove 25 is slidably engaged with the sliders 32.

[0026] Furthermore, the locking part 35 includes a hydraulic push rod 351 fixedly disposed on the inner wall of the lifting block 31, a locking block 352 fixedly disposed on the output end of the hydraulic push rod 351, a locking groove 353 that slides with the locking block 352, a pawl 354 that slides with the locking block 352 through the locking groove 353, a fixing seat 355 fixedly disposed on both sides of the pawl 354, a locking post 356 fixedly disposed on the fixing seat 355, a second fixing frame 357 that slides with the locking post 356, and a spring 358 fixedly disposed on the second fixing frame 357.

[0027] Furthermore, the second fixing frame 357 is fixedly connected to the outer wall of the support cabinet 21, and the end of the spring 358 away from the second fixing frame 357 is fixedly connected to the fixing base 355.

[0028] Furthermore, the detection mechanism 5 is fixedly mounted on the flipping frame 44.

[0029] Furthermore, the mobile component 1 includes a vehicle plate 11 fixedly disposed at the bottom of the support cabinet 21, wheels 12 disposed at the bottom of the vehicle plate 11, and a push handle 13 fixedly disposed on the vehicle plate 11.

[0030] When inspecting the seam of an upright ALC panel: First, the operator pushes the moving component 1 using the push handle 13, using the wheels 12 at the bottom of the platform 11 to move the entire device to the seam position of the ALC panel to be inspected. Step 1: Start the drive motor 22. The drive motor 22 drives the threaded shaft 23 to rotate. Since the threaded shaft 23 is threadedly engaged with the threaded hole 33 in the lifting block 31, and the slider 32 is slidably engaged with the limiting groove 25, it limits and guides the lifting block 31. Therefore, the rotational motion of the threaded shaft 23 is converted into the vertical upward motion of the lifting block 31. The lifting block 31 drives the first fixed frame 34, the flipping component 4, and the inspection mechanism 5 to rise vertically along the limiting groove 25. The inspection probe of the inspection mechanism 5 moves from the bottom to the top of the ALC panel, completing the inspection of the seam at the entire position of the ALC panel.

[0031] Furthermore, the flipping assembly 4 includes a flipping shaft 41 rotatably mounted on the first fixed frame 34, a ratchet 42 fixedly mounted on the flipping shaft 41, gears 43 fixedly mounted at both ends of the flipping shaft 41, and flipping frames 44 symmetrically mounted on the flipping shaft 41.

[0032] Furthermore, when the pawl 354 and the ratchet gear 42 are engaged, the flipping shaft 41 can only rotate clockwise within the first fixed frame 34; when the gear 43 moves vertically to the position of the toothed plate 24, the toothed plate 24 and the gear 43 mesh with each other.

[0033] When inspecting the ALC panel seams on the ceiling, the angle of the inspection mechanism 5 needs to be adjusted using the flipping assembly 4 so that the inspection probe of the inspection mechanism 5 faces the ceiling. The specific inspection process is as follows: Move the device directly below the ALC panel seams on the ceiling, start the drive motor 22, and drive the threaded shaft 23 to rotate, causing the lifting block 31 to drive the flipping assembly 4 and the inspection mechanism 5 to rise vertically until the gear 43 in the flipping assembly 4 moves to the position of the toothed plate 24 at the top of the support cabinet 21. At this time, the gear 43 and the toothed plate 24 mesh with each other. The drive motor 22 continues to drive the threaded shaft 23 to rotate, causing the lifting block 31 to continue to rise. Since the gear 43 and the toothed plate 24 mesh with each other, when the lifting block 31 rises, the gear 43 rotates clockwise under the action of the toothed plate 24. The gear 43 drives the flipping shaft 41 to rotate clockwise, and the flipping shaft 41 drives the flipping frame 44 and the inspection mechanism 5 to rotate clockwise together. When gear 43 moves to the top of toothed plate 24, the detection mechanism 5 completes a 90-degree rotation. The rotating frame 44 and the support cabinet 21 fit together to provide stable contact for the detection mechanism 5. Finally, the moving component 1 is pushed according to the trajectory of the seam, and the detection mechanism 5 can then detect the entire seam of the ALC panel on the ceiling.

[0034] Furthermore, the drive assembly 2 also includes a limiting post 26 fixedly mounted on the support cabinet 21; the flipping frame 44 has a limiting hole 441, which is inserted into the limiting post 26.

[0035] It should also be noted that when inspecting the vertically positioned ALC plate, the limiting post 26 is always inserted into the limiting hole 441 on the flipping frame 44 to prevent the flipping assembly 4 from flipping automatically, thus providing a stable inspection foundation for the inspection mechanism 5. Simultaneously, the pawl 354 is always engaged with the ratchet gear 42 during this process, further enhancing the inspection stability of the inspection mechanism 5.

[0036] When gear 43 moves to tooth plate 24, the limiting hole 441 disengages from limiting post 26, and gear 43 begins to drive ratchet 42 to rotate via flipping shaft 41. During rotation, under the elastic force of spring 358, pawl 354 intermittently engages with ratchet 42, and pawl 354 also reciprocates linearly on hydraulic push rod 351 via slide groove. When flipping frame 44 rotates 90 degrees, pawl 354 automatically engages with ratchet 42 to prevent the entire flipping assembly 4 from reversing, thus affecting the detection results.

[0037] When the detection mechanism 5 needs to switch from detecting an ALC board on the ceiling to detecting an ALC board installed vertically, the hydraulic push rod 351 is activated. The hydraulic push rod 351 retracts, causing the locking block 352 to move. As the side wall of the locking block 352 abuts against the inside of the groove in the pawl 354, the pawl 354 gradually moves away from the ratchet gear 42, the spring 358 is compressed again, and the locking post 356 moves stably within the second fixing frame 357, providing stability for the pawl 354. At this time, the reverse limit of the flipping assembly 4 is released, and by starting the drive motor 22 to drive the threaded shaft 23 to reverse, the position of the detection object can be switched.

[0038] In summary, this prestressed connection crack prevention detection device for prefabricated ALC panel joints in prefabricated buildings effectively achieves flexible switching between two detection states: vertical ALC panel joints and ceiling ALC panel joints, through the coordinated structure of the drive component, lifting component, and flipping component. This significantly expands the device's detection applicability, improves detection convenience and efficiency, and effectively solves the problem of limited detection scenarios in traditional detection devices. The structural design of the locking part and ratchet working in tandem prevents the flipping component from reversing, enhancing the device's detection stability in both detection states and ensuring accurate and reliable detection data. When detecting vertical ALC panel joints, the pawl of the locking part and the ratchet of the flipping component are always engaged, and with the limiting structure, prevent accidental flipping of the component, providing a stable posture for the detection mechanism. When detecting ceiling ALC panel joints, during the flipping of the component, the pawl intermittently engages with the ratchet under the spring force of the locking part, without affecting the smooth flipping and also providing temporary limiting to avoid structural damage. The structural design of the limiting post and limiting hole further enhances the structural stability of the device during the detection process, providing a reliable support foundation for the detection mechanism and effectively avoiding detection deviations. When inspecting the seams of vertically installed ALC panels, the limiting pins on the drive assembly are inserted into the limiting holes of the flipping frame of the flipping assembly, forming a double limiting structure. Together with the locking part and ratchet, this prevents the flipping assembly from automatically flipping or shaking during lifting or inspection, ensuring that the inspection probe is aligned with the seam to be inspected, thus guaranteeing the continuity and accuracy of the inspection.
