Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to an installation support device for prefabricated building components. Background Technology

[0002] Prefabricated building components refer to building components that are manufactured and assembled in factories or production bases. Prefabricated components can include various components such as wall panels, floor slabs, beams, columns, and roof trusses.

[0003] During the installation of precast building components, in order to maintain the stability and safety of the installation process and prevent the components from tipping over, support devices are needed to support the components. Existing support devices generally use steel reinforcement frames to connect the precast components to the ground, so that a stable triangular support area can be formed between the precast components, the ground, and the steel reinforcement frames. When the precast components are large, the number of steel reinforcement frames required will also increase, making it difficult to quickly adapt to precast components of different sizes, thus resulting in cumbersome support procedures and increased time costs.

[0004] Therefore, in order to address the above problems, we are now developing a prefabricated building component installation support device that can quickly adjust the support center of gravity position and adapt to prefabricated components of different specifications. Summary of the Invention

[0005] To overcome the shortcomings of existing devices that are difficult to quickly adapt to prefabricated components of different specifications, resulting in cumbersome support steps and increased time costs, this invention provides a prefabricated building component installation support device that can quickly adjust the support center of gravity position and adapt to prefabricated components of different specifications.

A first spring is provided between each latch and an adjacent second rotating member. A sliding base is rotatably mounted between adjacent second rotating members, and the sliding base is slidably connected to the limiting frame.

[0007] In one embodiment, an extension mechanism is also included. The extension mechanism includes a first extension plate, a second extension plate, a connecting rod, a first gear, a rack frame, and a timing belt assembly.

The second extension plate is provided on the non-adjacent side of each connecting rod. The first gear is rotatably provided at the bottom of each of the first extension plates. The rack frame that can mesh with the adjacent first spur gear is provided at the bottom of each of the second extension plates. The timing belt assembly is provided between the first gears.

[0008] In one embodiment, a lifting mechanism is also included. The lifting mechanism includes a second lead screw, a third rotating member, a second gear, and a drive motor. The upper sides of both the front and rear parts of the limiting frame are provided with second lead screws, which are slidably connected to the mounting plate. The lower sides of both the front and rear parts of the mounting plate are rotatably provided with third rotating members, each of which is provided with a second gear. The upper sides of both the front and rear parts of the mounting plate are provided with drive motors, and the output shafts of the drive motors are also provided with second gears. Adjacent second gears mesh with each other.

[0009] In one embodiment, a clamping mechanism is also included. The clamping mechanism includes a lifting frame, a first limiting member, a second spring, a fixed seat, a flipping assembly, a clamping member, and a third spring. The left side of the mounting seat is provided with symmetrical first limiting members. A lifting frame that can be supported and limited by the limiting frame is slidably arranged between the first limiting members. A second spring is provided between the lifting frame and the first limiting members. A fixed seat is provided on the left side of the mounting seat. A flipping assembly that is limited and locked by the lifting frame is rotatably arranged on the fixed seat. A clamping member for clamping and limiting the first mounting member is slidably arranged on the flipping assembly. A third spring is provided between the clamping member and the flipping assembly.

[0010] In one embodiment, a moving mechanism is also included. The moving mechanism includes a second mounting member and a moving wheel. The second mounting member is provided on both the front and rear sides of the left and right sides of the mounting base, and the moving wheel is rotatably provided on the bottom of each second mounting member.

[0011] In one embodiment, a blocking mechanism is also included. The blocking mechanism includes a second limiting member and a sliding rod. The second limiting member is provided on each non-adjacent side of the second rotating member, and a sliding rod is slidably provided on each of the second limiting members.

[0012] In one embodiment, a turntable for easy operation is provided on the right side of the first lead screw.

[0013] In one embodiment, pull rings are provided on both sides of the bolt that are not adjacent to each other.

[0014] In one embodiment, the timing belt assembly includes timing pulleys and a timing belt, with timing pulleys provided on each of the first gears, and a timing belt wound between the timing pulleys.

[0015] In one embodiment, the flipping assembly includes a flipping element and torsion springs. The flipping element is rotatably mounted on the fixed base, and two torsion springs symmetrically arranged between the flipping element and the fixed base are provided, with the torsion springs both wound around the flipping element.

[0016] Compared with the prior art, the present invention has the following advantages: 1. The present invention can adapt to prefabricated building components of different specifications by adjusting the height of the mounting base and the position of the sliding base, thereby adjusting the center of gravity of the corresponding prefabricated building components, increasing the support area of ​​the limiting frame, and improving the support stability.

[0017] 2. The present invention causes the adjacent rack frame to rotate by pulling the second extension plate on one side, thereby causing the first gear to rotate under the action of the synchronous belt assembly. This causes the other first gear to move the adjacent rack frame, thereby causing the second extension plate on the other side to slide and unfold, achieving the effect of synchronous adjustment and unfolding, increasing the contact area between the first mounting part and the prefabricated part, and enhancing the support effect.

[0018] 3. The present invention drives the output shaft of the drive motor to drive the second gear to rotate, thereby enabling the third rotating component to automatically drive the mounting plate to be lifted along the second lead screw, improving the convenience of operation. At the same time, the self-locking effect between the second lead screw and the third rotating component ensures that the mounting plate remains stable.

[0019] 4. The present invention uses a clamping component and a third spring to clamp and limit the first mounting component, preventing the first mounting component from accidentally flipping and lifting under normal conditions and affecting placement. At the same time, when it is needed, as the mounting plate is raised, the lifting frame can automatically slide down to unlock the flipping component, thereby making the flipping component automatically flip and unlock the first mounting component, improving the convenience of use.

[0032] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0033] A prefabricated building component installation support device, such as Figure 1 and Figure 2 As shown, it includes a mounting base 1, a sliding member 2, a first lead screw 3, a hydraulic cylinder 4, a first mounting component 5, and a support mechanism 6. The top of the mounting base 1 is slidably connected to the sliding member 2, and the rear of the mounting base 1 is rotatably connected to the first lead screw 3. The right side of the first lead screw 3 is connected to a turntable for easy operation. The first lead screw 3 is threadedly connected to the sliding member 2. The sliding member 2 is rotatably connected to the hydraulic cylinder 4. The telescopic end of the hydraulic cylinder 4 is connected to the first mounting component 5 for connecting and supporting prefabricated building components. The mounting base 1 is mounted on the support mechanism 6, which can improve the stability of the support.

[0034] It should be noted that this device can be used to provide auxiliary support for prefabricated building components during installation. First, the state of the support mechanism 6 is adjusted according to the specifications of the prefabricated component, thereby adjusting the height of the mounting base 1. After adjustment, the first lead screw 3 is rotated to adjust the position of the sliding member 2. Then, the hydraulic cylinder 4 is flipped upward and lifted, and the extension end of the hydraulic cylinder 4 is controlled to drive the first mounting member 5 to move, so that the first mounting member 5 can contact the surface of the prefabricated building component. Then, the first mounting member 5 is fixedly connected by bolts, thereby achieving the effect of supporting and stabilizing prefabricated building components of different specifications.

[0035] like Figure 1 , Figure 3 and Figure 4 As shown, the support mechanism 6 includes a mounting plate 61, a limiting frame 62, a first rotating component 63, a second rotating component 64, a latch 65, a first spring 66, and a sliding base 67. The mounting plate 61 is slidably connected to the limiting frame 62. The mounting base 1 is mounted on the mounting plate 61 by bolts. The first rotating component 63 is rotatably connected to the left and right sides of the mounting plate 61. The second rotating component 64 is slidably connected to each of the first rotating components 63. The second rotating component 64 is slidably connected to a latch 65 that can engage with the adjacent first rotating component 63. A pull ring is connected to the non-adjacent side of the latch 65. The first spring 66 is connected between the latch 65 and the adjacent second rotating component 64. The first spring 66 is wound around the adjacent latch 65. The sliding base 67 for enhancing the support effect is rotatably connected between the front and rear adjacent second rotating components 64. The sliding base 67 is slidably connected to the limiting frame 62.

[0036] It should be noted that during the installation of prefabricated building components, the position of the mounting base 1 needs to be adjusted according to the different specifications of the prefabricated components. First, pull the bolts 65 outwards to the side away from each other, so that the first springs 66 are stretched, thereby freeing the second rotating component 64 from the locked state. Then, pull the sliding base 67 outwards along the limiting frame 62 to the side away from each other, increasing the support area and improving the support effect. After the sliding base 67 is pulled out, release the bolts 65, allowing the bolts 65 to slide back to their original position under the action of the first springs 66, and then... The second rotating component 64 is locked and fixed. Then, the mounting plate 61 is pulled upward along the limiting frame 62, so that the first rotating component 63 starts to drive the second rotating component 64 to rotate, thereby making the angle adaptable and stable, achieving the effect of adapting and supporting prefabricated building components of different specifications. In summary, by adjusting the height of the mounting base 1 and the position of the sliding base 67, prefabricated building components of different specifications can be adapted, the center of gravity position of the corresponding prefabricated building components can be adjusted, the support area of ​​the limiting frame 62 can be increased, and the support stability can be improved.

[0037] like Figure 1 , Figure 5 and Figure 6 As shown, it also includes an expansion mechanism 7, which includes a first expansion plate 71, a second expansion plate 72, a connecting rod 73, a first gear 74, a rack frame 75, and a timing belt assembly 76. The bottom of the first mounting member 5 is connected to the first expansion plate 71, and the top of the first expansion plate 71 is slidably connected to the connecting rod 73. The non-adjacent sides of the connecting rod 73 are connected to the second expansion plate 72. The cooperation between the first expansion plate 71 and the second expansion plate 72 can increase the support area of ​​the first mounting member 5. The bottom of the first expansion plate 71 is rotatably connected to the first gear 74, and the bottom of the second expansion plate 72 is connected to the rack frame 75 that can mesh with the adjacent first spur gear. The timing belt assembly 76 is connected between the first gears 74. The timing belt assembly 76 includes a timing pulley and a timing belt. The first gear 74 is connected to the timing pulley, and the timing belt is wound between the timing pulleys.

[0038] It should be noted that, in order to further improve the support effect of the first mounting component 5 on the prefabricated component, one of the second extension plates 72 can be pulled outward, so that the corresponding connecting rod 73 slides outward along the first extension plate 71. At this time, the pulled second extension plate 72 will drive the adjacent rack frame 75 to move, thereby causing the corresponding first gear 74 to rotate. When the first gear 74 starts to rotate, it will cause the synchronous belt assembly 76 to operate, which in turn causes the other first gear 74 to start driving the adjacent rack frame 75 to move. Then, the rack frame 75 drives the other second extension plate 72 to slide out accordingly, achieving the effect of synchronous adjustment. In summary, by pulling the second extension plate 72 on one side, the adjacent rack frame 75 drives the first gear 74 to rotate, thereby causing the other first gear 74 to drive the adjacent rack frame 75 to move under the action of the synchronous belt assembly 76, which in turn causes the second extension plate 72 on the other side to slide out, achieving the effect of synchronous adjustment and expansion, increasing the contact area between the first mounting component 5 and the prefabricated component, and enhancing the support effect.

[0039] like Figure 1 and Figure 7 As shown, it also includes a lifting mechanism 8, which includes a second lead screw 81, a third rotating component 82, a second gear 83, and a drive motor 84. The upper sides of the front and rear parts of the limit frame 62 are connected to the second lead screw 81, and the second lead screw 81 is slidably connected to the mounting plate 61. The lower sides of the front and rear parts of the mounting plate 61 are rotatably connected to the third rotating component 82, and the second gear 83 is connected to the third rotating component 82. The upper sides of the front and rear parts of the mounting plate 61 are connected to the drive motor 84, and the output shafts of the drive motor 84 are all oriented downwards. The output shafts of the drive motor 84 all pass through the mounting plate 61, and the second gear 83 is also connected to the output shafts of the drive motor 84. The two adjacent second gears 83 mesh with each other.

[0040] It should be noted that when the support height of the mounting plate 61 needs to be adjusted, the drive motor 84 can be started directly. The output shaft of the drive motor 84 will drive the adjacent second gear 83 to rotate, thereby causing the corresponding second gear 83 to drive the adjacent third rotating component 82 to rotate. When the third rotating component 82 starts to rotate, it will drive the mounting plate 61 to move upward along the second lead screw 81, achieving an automatic lifting effect. After the lifting is completed, the drive motor 84 is turned off. In summary, by driving the second gear 83 to rotate through the output shaft of the drive motor 84, the third rotating component 82 can automatically drive the mounting plate 61 to lift along the second lead screw 81, improving the convenience of operation. At the same time, the self-locking effect between the second lead screw 81 and the third rotating component 82 ensures that the mounting plate 61 remains stable.

[0041] like Figure 1 , Figure 8 and Figure 9 As shown, it also includes a pressing mechanism 9, which includes a lifting frame 91, a first limiting member 92, a second spring 93, a fixed seat 94, a flipping assembly 95, a pressing member 96, and a third spring 97. The left side of the mounting base 1 is bolted to the symmetrically arranged first limiting members 92. The lifting frame 91 is slidably connected between the first limiting members 92. The lifting frame 91 is supported and limited by the limiting frame 62. A second spring 93 is connected between the lifting frame 91 and the first limiting members 92. The left side of the mounting base 1 is bolted to the fixed seat 94. A flipping assembly 95 is rotatably connected to the base 94. The flipping assembly 95 is limited and locked by the lifting frame 91. The flipping assembly 95 includes a flipping element and a torsion spring. The flipping element is rotatably connected to the fixed base 94. Two torsion springs are connected between the flipping element and the fixed base 94, and the torsion springs are both wound around the flipping element. A clamping element 96 is slidably connected to the flipping assembly 95. The clamping element 96 is used to clamp and limit the first mounting part 5. A third spring 97 is connected between the clamping element 96 and the flipping assembly 95. The third spring 97 is all wound around the clamping element 96.

[0042] It should be noted that, to prevent the first mounting component 5 from accidentally flipping and lifting under normal conditions, the clamping component 96 and the third spring 97 can cooperate to lock and limit the first mounting component 5. When the mounting base 1 begins to lift and adjust upwards, the mounting plate 61 will move away from the limiting frame 62. Initially, the second spring 93 is in a compressed state. As the mounting plate 61 moves away from the limiting frame 62, the lifting frame 91 is no longer supported and limited by the limiting frame 62. Under the action of the second spring 93, the lifting frame 91 will slide downwards, thus no longer limiting and locking the flipping component 95. This allows the flipping component 95 to automatically flip to the left, causing the clamping component 96 to move to the left, thus removing the clamping limit on the first mounting component 5. The first mounting component 5 can then be raised and used normally. In summary, by clamping the first mounting component 5 with the clamping component 96 and the third spring 97, the accidental flipping and lifting of the first mounting component 5 under normal conditions can be avoided, thus preventing it from affecting placement. At the same time, when it is needed, as the mounting plate 61 is raised, the lifting frame 91 can automatically slide down to unlock the flipping component 95, thereby allowing the flipping component 95 to automatically flip and unlock the first mounting component 5, improving ease of use.

[0043] like Figure 1 and Figure 10 As shown, it also includes a moving mechanism 10, which includes a second mounting component 101 and a moving wheel 102. The front and rear sides of the left and right sides of the mounting base 1 are connected to the second mounting component 101 by bolts, and the bottom of the second mounting component 101 is rotatably connected to the moving wheel 102 for auxiliary movement.

[0044] It should be noted that when this device is needed to support prefabricated building components, in order to improve the convenience of handling, the mounting base 1 can be directly pushed, and the mounting base 1 can move under the cooperation of the moving wheels 102.

[0045] like Figure 1 and Figure 11 As shown, it also includes a blocking mechanism 11, which includes a second limiting member 111 and a sliding rod 112. The second limiting member 111 is connected to the non-adjacent side of the second rotating member 64. The sliding rod 112 for blocking and limiting the adjacent latches 65 is slidably connected to the second limiting member 111.

[0046] It should be noted that when the latch 65 is pulled outward, the sliding rod 112 can be pushed towards the side closer to the latch 65, so that the sliding rod 112 can engage with the adjacent latch 65, thereby blocking the latch 65 and preventing the latch 65 from automatically resetting. This eliminates the need for the operator to constantly pull the latch 65, further improving the convenience of operation.

The scope of the following claims should be given the broadest interpretation so as to cover all variations and equivalent structures and functions.
