Description

Technical Field

[0001] This invention relates to the field of wall panel construction equipment technology, and in particular to a rapid positioning and support device for metal panel walls. Background Technology

[0002] The rapid positioning and support device for metal panel walls is a specialized auxiliary device for the installation of metal panel walls in fields such as building decoration and industrial plants. Its core function is to quickly and accurately position metal panels during installation, replacing the traditional manual lifting and cumbersome alignment methods.

[0003] For example, Chinese patent CN217871897U discloses a wall panel quick positioning adjuster, which includes a U-shaped support plate. The top of the front and rear sides of the U-shaped support plate is provided with symmetrically distributed support horizontal plates. The top of each of the two support horizontal plates is provided with a positioning mechanism. The positioning mechanism includes two symmetrically arranged support vertical plates. A connecting plate is provided between the two support vertical plates. A threaded rod is threadedly connected to the middle of the outer side of the connecting plate. The inner end of the threaded rod passes through the front side of the connecting plate and is rotatably connected to a circular extrusion plate.

[0004] The aforementioned patent describes a method for fixing vertical lightweight wall panels using two positioning mechanisms, which improves construction efficiency. However, existing quick positioning devices still have some shortcomings that need improvement. Specifically, after fixing the metal panel, they generally lack a supporting stable structure, resulting in the metal panel not receiving effective support. The metal panel is susceptible to construction vibrations and its own weight, causing unexpected shaking and positional shifts during the installation and subsequent construction phases. This not only directly damages the initial positioning accuracy and causes excessive installation deviations of the metal panel, seriously affecting the overall project quality, but may also lead to uneven stress on the connecting structure due to panel shifts, posing a potential risk to structural stability in subsequent use. Summary of the Invention

[0008] Furthermore, the first drive assembly includes a first assembly slot, which is formed inside one side of the assembly frame.

[0009] Furthermore, the support mechanism also includes a fixing plate, which is rotatably connected to both sides of the top of the assembly frame via a second transmission mechanism. Connecting grooves are provided on both sides of the interior of the fixing plate, and a connecting rod is slidably connected inside the connecting groove. A support plate is fixedly connected to one side of the connecting rod, and one side of the support plate is located inside the placement groove. The top side of the support plate has an arc-shaped structure, and a rubber sheet is fixedly connected to the arc. A snap-fit ​​assembly is provided between the connecting rod and the connecting groove. Limiting grooves are provided on both sides of the interior of the connecting groove, and limiting blocks are slidably connected to both sides of the interior of the limiting groove. The limiting blocks are fixedly connected to both sides of one end of the connecting rod.

[0010] Furthermore, the snap-fit ​​assembly includes a spring, which is fixedly connected to both sides of the inside of the fixing plate.

[0013] Compared with the prior art, the beneficial effects of the present invention are: In this invention, the first transmission mechanism drives the contact plate to slide towards the limiting plate. The bidirectional clamping action of the limiting plate and the contact plate achieves initial firm positioning of both sides of the bottom of the metal plate. Then, the second transmission mechanism synchronously adjusts the angle and position of the support mechanisms on both sides of the top of the assembly frame, ensuring that the support mechanisms are tightly fitted and in contact with the inner wall of the metal plate. This forms a multi-point inner support limiting and fixing structure, which, together with the outer clamping structure, forms a dual-fixing support system that works in tandem with the outer side. This achieves comprehensive reinforcement of the metal plate after rapid positioning, fundamentally preventing shaking and displacement of the metal plate during construction. It significantly improves the positioning accuracy and stability of the metal plate after installation, ensuring construction quality while reducing construction safety hazards.

[0016] 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.

[0017] Please see Figures 1-11 In this embodiment of the invention, a rapid positioning support device for a metal plate wall includes an assembly frame 1 and a metal plate 2. Limiting plates 3 are fixedly connected to both sides of the top of the assembly frame 1. An abutment plate 4 is provided on one side of the limiting plates 3 on the assembly frame 1. Rubber pads are fixedly connected to the contact surfaces of the limiting plates 3 and the abutment plate 4. The bottom sides of the metal plate 2 are located between the limiting plates 3 and the abutment plate 4. Placement grooves 41 are provided on both sides of the top of the abutment plate 4, and rubber sheets are fixedly connected within the placement grooves 41. The rubber pad and rubber sheet can form a flexible contact protection structure to avoid surface scratches and pressure damage caused by hard contact between the device and the metal plate 2. At the same time, it increases the contact friction and improves the stability of clamping and support. A first transmission mechanism 5 is provided on one side of the assembly frame 1. The abutment clamp 4 is slidably connected to both sides of the top of the assembly frame 1 through the first transmission mechanism 5. A support mechanism 6 is provided in the middle of the top of the assembly frame 1. The support mechanism 6 includes a support plate 62. One side of the support plate 62 is movably inserted into the interior of the placement groove 41. When the abutting clamp 4 moves, it drives the support plate 62 to move synchronously through the placement groove 41. The other side of the assembly frame 1 is provided with a second transmission mechanism 7. The independent setting of the first transmission mechanism 5 and the second transmission mechanism 7 can realize the clamping and positioning of the metal plate 2 and the adjustment of the inner support, respectively. The cooperative setting of the support mechanism 6 and the abutting clamp 4 can form a double fixation from the two dimensions of clamping the metal plate 2 from the outside and supporting the inside, which can ensure the installation stability of the metal plate 2 in all aspects, effectively prevent shaking and displacement during construction, improve positioning accuracy and construction quality. The overall device has a compact structure and can quickly complete the positioning and support operation of the metal plate 2. The present invention achieves the effect of positioning and alignment through the linkage design of the placement groove and the support plate. While driving the abutting clamp for external positioning, the internal support mechanism automatically follows and moves to the area to be supported without secondary alignment. Moreover, by utilizing the adaptive sliding of the connecting rod and the self-locking characteristics of the worm gear, a dynamically adaptable but statically stable triangular support system is formed, which effectively solves the problem of secondary displacement during installation.

[0018] Please see Figure 8The first transmission mechanism 5 includes a slide groove 52, which is formed inside the top edge of the assembly frame 1 on both sides. A lead screw 51 is rotatably connected inside the slide groove 52, and a screw block 53 is threadedly connected to the outer surface of the lead screw 51. The screw block 53 is slidably connected inside the slide groove 52, and the top end of the screw block 53 is fixedly connected to the bottom end of the abutment clamp 4. A first drive assembly 58 is provided on the assembly frame 1 between the two slide grooves 52. Guide grooves 54 are formed on both sides of the slide groove 52, and guide blocks 55 are slidably connected inside the guide grooves 54. The guide blocks 55 are fixedly connected to both sides of the screw block 53. A baffle 57 is fixedly connected to the side of the screw block 53 away from the guide block 55. A receiving groove 56 is formed on one side of the slide groove 52. One side of the plate 57 is slidably connected to the inside of the storage groove 56. Through the cooperation of the sliding groove 52, the lead screw 51, the screw block 53, the guide groove 54, the guide block 55, the baffle 57, and the storage groove 56, the contact clamp 4 can be smoothly and accurately slid. The guide groove 54 and the guide block 55 can limit the sliding trajectory of the screw block 53, preventing the screw block 53 from shifting as the lead screw 51 rotates, ensuring that the contact clamp 4 always moves horizontally, and ensuring the symmetry of clamping the metal plate 2. The cooperation of the baffle 57 and the storage groove 56 can effectively limit the sliding stroke of the screw block 53, preventing the screw block 53 from sliding excessively and causing structural damage. At the same time, it prevents part of the lead screw 51 from being exposed and introducing impurities, further improving the safety of the device and providing a stable guarantee for the rapid and accurate positioning of the metal plate 2.

[0019] Please see Figure 5The first drive assembly 58 includes a first mounting groove 585, which is located inside one side of the assembly frame 1. A first shaft 584 is rotatably connected inside the first mounting groove 585. The first shaft 584 is fixedly connected between two lead screws 51. A first driven toothed bevel 583 is fixedly connected to one side of the first shaft 584. A first driving toothed bevel 582 is meshed with one side of the first driven toothed bevel 583. A first torsion wheel 581 is fixedly connected to one side of the first driving toothed bevel 582. A first groove 586 is provided on one side of the assembly frame 1, and the first torsion wheel 581 is rotatably connected inside the first groove 586. The first transmission mechanism 5 can be converted into a power direction conversion by the cooperation of the first assembly groove 585, the first shaft 584, the first driven tooth cone 583, the first driving tooth cone 582, the first torsion wheel 581, and the first groove 586. This converts the horizontal rotation of the first torsion wheel 581 into the vertical rotation of the first shaft 584, thereby synchronously driving the lead screws 51 on both sides to rotate, achieving synchronous movement of the two sides of the contact clamping plates 4. This ensures that the clamping force on both sides of the metal plate 2 is uniform and consistent, avoiding the metal plate 2 from shifting due to excessive clamping on one side. The first groove 586 can conceal the first torsion wheel 581, preventing it from being exposed to the outside of the assembly frame 1 during construction and easily damaged.

[0020] Please see Figures 8-10The support mechanism 6 includes a fixed plate 61, which is rotatably connected to both sides of the top of the assembly frame 1 via a second transmission mechanism 7. Both sides of the fixed plate 61 have connecting grooves 64, and connecting rods 63 are slidably connected inside the connecting grooves 64. A support plate 62 is fixedly connected to one side of the connecting rod 63. One side of the support plate 62 is located inside the placement groove 41. The top side of the support plate 62 has an arc-shaped structure, and a rubber sheet is fixedly connected to the arc. A snap-fit ​​assembly 65 is provided between the connecting rod 63 and the connecting groove 64. Limiting grooves 631 are formed on both sides of the inner side of the connecting groove 64. Limiting blocks 641 are slidably connected to both sides of the inner side of the limiting grooves 631. The limiting blocks 641 are fixedly connected to both sides of one end of the connecting rod 63. Through the cooperation of the fixing plate 61, connecting rod 63, support plate 62, connecting groove 64, limiting grooves 631, limiting blocks 641, and snap-fit ​​assembly 65, stable support for the inner side of the metal plate 2 can be achieved. The arc-shaped structure of the support plate 62 can better fit the inner wall of the metal plate 2, increase the contact area, and improve the stability of the support. The rubber at the arc... The plate further enhances the flexible contact effect, avoiding scratches on the surface of the metal plate 2 during support. The sliding fit between the connecting rod 63 and the connecting groove 64 is used not only to adjust the length but also to compensate for differences in movement trajectory. Since the contact clamp 4 moves linearly while the support plate 62 rotates with the fixed plate 61, there is a displacement difference between the two. During the movement of the contact clamp 4 and the support plate 62, the connecting rod 63 will automatically slide and extend within the connecting groove 64 to adapt to this displacement change, thereby preventing the mechanism from jamming and achieving smooth linkage adjustment. One side is elastically inserted into the placement groove 41 of the contact clamp 4, allowing the support plate 62 to move with the contact clamp 4. The limiting groove 631 and the limiting block 641 can limit and guide the sliding of the connecting rod 63, preventing the connecting rod 63 from shifting or falling off during the sliding process, ensuring the accurate support position of the support plate 62. The snap-fit ​​component 65 can firmly lock the adjusted connecting rod 63, preventing the connecting rod 63 from sliding on its own during the support process and causing support failure, further ensuring the stability of the support mechanism 6, and forming a synergy with the outer clamping structure to fix the metal plate 2 in all directions.

[0021] Please see Figure 11The snap-fit ​​assembly 65 includes a spring 652, which is fixedly connected to both sides of the inside of the fixing plate 61. A connecting block 651 is fixedly connected to one side of the spring 652, and a snap-fit ​​block 653 is fixedly connected to one side of the connecting block 651. A snap-fit ​​groove 654 is provided on one side of the connecting rod 63. The snap-fit ​​block 653 has an arc-shaped structure and matches the snap-fit ​​groove 654. Through the cooperation of the spring 652, the connecting block 651, the snap-fit ​​block 653, and the snap-fit ​​groove 654, after the support plate 62 moves to a suitable position, the support plate 62 can be fixed with the fixing plate 61, so that the support plate 62 contacts the inner chamfer of the metal plate 2, thereby limiting and supporting it.

[0022] Please see Figure 6 The second transmission mechanism 7 includes a transmission block 71, which is fixedly connected to one side of the fixed plate 61. A transmission rod 72 is fixedly connected between the two transmission blocks 71. A worm gear 75 is fixedly connected to the middle of the transmission rod 72. A second assembly groove 76 is provided inside the middle side of the assembly frame 1. A second shaft 73 is rotatably connected inside the second assembly groove 76. Worms 74 are fixedly connected to both sides of the second shaft 73. The worm gear 74 meshes with the worm wheel 75. The worm wheel 75 and the worm gear 74 form a self-locking transmission structure, which is used to lock the position of the support mechanism 6 by utilizing the self-locking characteristic after the support plate 62 is adjusted to a predetermined angle, preventing the metal plate 2 from shifting angle under external force. The assembly frame 1 has a second drive assembly 77 on the side away from the first drive assembly 58. Through the cooperation of the transmission block 71, transmission rod 72, worm gear 75, second assembly groove 76, second shaft 73, worm 74, and second drive assembly 77, the synchronous angle adjustment of the two fixed plates 61 can be realized, thereby driving the support plate 62 to adjust the support angle synchronously. This ensures that the support force of the two support plates 62 on the metal plate 2 is uniform and the support position is symmetrical, avoiding the tilting and displacement of the metal plate 2 caused by the deviation of the support on one side. The meshing transmission of the worm gear 75 and the worm 74 has a self-locking function. After the adjustment is completed, the position of the fixed plate 61 can be firmly locked to prevent the fixed plate 61 from rotating due to vibration during construction, thus ensuring the stability of the support mechanism 6.

[0023] Please see Figure 2 and Figure 6The second drive assembly 77 includes a second groove 774, which is formed on the mounting bracket 1 on the opposite side of the first groove 586. A second torsion wheel 771 is rotatably connected inside the second groove 774. A second driving tooth cone 772 is fixedly connected to one side of the second torsion wheel 771, and a second driven tooth cone 773 is meshed with one side of the second driving tooth cone 772. The second driven tooth cone 773 is fixedly connected to the second shaft 73. The drive assembly 777 is formed by the second groove 774, the second torsion wheel 771, the second driving tooth cone 772, and the second driven tooth cone. The cooperation of 773 and the second shaft 73 enables the conversion of the power direction of the second transmission mechanism 7, converting the horizontal rotation of the second torsion wheel 771 into the vertical rotation of the second shaft 73, thereby driving the worm gear 74 to rotate. The operation is simple and allows the operator to quickly adjust the angle of the support mechanism 6. The second groove 774 can conceal the second torsion wheel 771, preventing it from being exposed to the outside of the assembly frame 1 during construction and thus preventing damage. The drive components of the two transmission mechanisms are respectively set on both sides of the assembly frame 1, without interfering with each other, making it convenient for the operator to perform clamping, positioning and support adjustment operations respectively.

[0024] The working principle of this invention is as follows: The operator first moves the metal plate 2 to be installed above the assembly frame 1, adjusts the position of the metal plate 2 so that the two sides of the bottom end of the metal plate 2 are aligned with the gap between the limiting abutment plate 3 and the contact clamping plate 4 on the two sides of the top end of the assembly frame 1, ensuring that the metal plate 2 is placed vertically and that the installation center line of the metal plate 2 is consistent with the center line of the assembly frame 1, avoiding the initial position deviation that would lead to a decrease in subsequent positioning accuracy. Then, the first torsion wheel 581 in the first groove 586 on one side of the assembly frame 1 is rotated. When the first torsion wheel 581 rotates, it will drive the first active tooth cone 582 fixedly connected to one side to rotate synchronously. Since the first active tooth cone 582 and the first driven tooth cone 582 in the first assembly groove 585 rotate synchronously, the first active tooth cone 582 and the first driven tooth cone 582 in the first assembly groove 585 rotate synchronously. The toothed bevel 583 meshes with the first driving toothed bevel 582, thus the rotation of the first driven toothed bevel 583 drives the first driven toothed bevel 583 to rotate synchronously, thereby driving the first shaft 584 fixedly connected to one side of the first driven toothed bevel 583 to rotate. When the first shaft 584 rotates, it synchronously drives the lead screw 51 in the sliding grooves 52 on both sides of the top edge of the assembly frame 1 to rotate. When the lead screw 51 rotates, the screw block 53 threaded to its outer surface slides horizontally in the sliding groove 52. During the sliding of the screw block 53, the guide blocks 55 fixedly connected to its two sides slide synchronously in the guide grooves 54 on both sides inside the sliding groove 52. The cooperation between the guide blocks 55 and the guide grooves 54 strictly limits the sliding trajectory of the screw block 53, preventing the screw block 53 from rotating with the lead screw 51. The displacement ensures that the screw block 53 always slides horizontally and linearly, thereby driving the abutment plate 4 fixedly connected to the top of the screw block 53 to move synchronously towards the limiting abutment plate 3. During the movement of the abutment plate 4, the cooperation between the baffle plate 57 and the storage groove 56 effectively limits the sliding stroke of the screw block 53, preventing the screw block 53 from sliding excessively and causing damage to the lead screw 51, screw block 53, or abutment plate 4. At the same time, it prevents the part of the lead screw 51 after sliding from being exposed and contaminated with impurities. When the rubber pad on the contact surface of the abutment plate 4 is tightly attached to the outer wall of the metal plate 2, and the rubber pad on the contact surface of the limiting abutment plate 3 is also tightly attached to the other outer wall of the metal plate 2, the rotation of the first torsion wheel 581 is stopped. At this time, the limiting abutment plate 3 and the abutment plate 4 are in close contact. The clamping plate 4 forms a two-way clamping structure, firmly clamping the bottom two sides of the metal plate 2, completing the initial positioning of the metal plate 2. During the clamping process, the rubber pad will increase the contact friction between the rubber pad and the metal plate 2, improving the stability of the clamping, and forming a flexible contact protection. During the clamping process, as the clamping plate 4 moves, the support plate 62 moves, and the connecting rod 63 slides in the connecting groove 64 of the fixing plate 61. At the same time, the limiting block 641 slides in the limiting groove 631 to limit the connecting rod 63 until the locking block 653 is locked and fixed with the locking groove 654 under the action of the spring 652, so as to stretch the length of the support plate 62 to make it fit against the inner side of the metal plate 2, so that the support plate 62 is connected and fixed to the fixing plate 61. After the metal plate 2 is initially clamped and positioned, the second torsion wheel 771 in the second groove 774 on the other side of the assembly frame 1 is rotated. When the second torsion wheel 771 rotates, it will drive the second active tooth cone 772 fixedly connected to one side to rotate synchronously. Since the second active tooth cone 772 is meshed with the second driven tooth cone 773 in the second assembly groove 76, the rotation of the second active tooth cone 772 will drive the second driven tooth cone 773 to rotate synchronously, thereby driving the second shaft 73 fixedly connected to the second driven tooth cone 773 to rotate. When the second shaft 73 rotates, it will drive the worm gear 74 fixedly connected to both sides to rotate synchronously. The worm gear 74 is meshed with the worm wheel 75 fixedly connected to the middle of the transmission rod 72. Therefore, the rotation of the worm gear 74 will drive the worm wheel 75 to rotate synchronously, thereby driving the transmission rods 72 on both sides of the worm wheel 75 to rotate. When the transmission rods 72 rotate, they will drive the transmission blocks 71 fixedly connected to both ends to rotate synchronously. The transmission block 71 is fixedly connected to the fixed plate 61. Therefore, the rotation of the transmission block 71 will drive the fixed plates 61 on both sides of the top of the assembly frame 1 to rotate synchronously, and then drive the support plate 62 on the fixed plate 61 to rotate synchronously. Adjust the angle of the support plate 62. When the arc surface of the support plate 62 is tightly attached to the inner wall of the metal plate 2, stop rotating the second torsion wheel 771. At this time, the meshing transmission of the worm gear 75 and the worm 74 has a self-locking function, which can realize the position of the fixed plate 61, transmission rod 72, transmission block 71 and other components to be firmly locked, preventing the fixed plate 61 from rotating due to vibration during construction, ensuring the support stability of the support mechanism 6, and avoiding support failure. The arc structure of the support plate 62 can better fit the inner wall of the metal plate 2, increase the contact area, and improve the stability of the support. The rubber sheet at the arc further enhances the flexible contact effect and avoids scratching the surface of the metal plate 2 during the support process. The dual-fixing structure, consisting of external bidirectional clamping and internal multi-point support, fundamentally prevents unexpected shaking and positional shifts of the metal plate 2 during the installation and subsequent construction phases due to factors such as construction vibration and its own weight. This completely solves the problems of low positioning accuracy and excessive installation deviation in existing devices, significantly improving the positioning accuracy and post-installation stability of the metal plate 2, effectively ensuring the overall project quality. At the same time, it avoids uneven stress on the connection structure caused by plate shifting, eliminating potential risks to structural stability during subsequent use and reducing construction safety hazards.
