[0045] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0046] like Figures 1-10 As shown, a support system and its construction method for installing prefabricated buildings are described. According to the requirements of the wall panels, the lower-level shells 2 can be installed sequentially to support the wall panels and improve the support effect. Specifically, the system includes a lower-level shell 2 extending in the left-right direction. The lower end of the lower-level shell 2 is provided with multiple support components spaced left-right. The top of the support components can be installed below the lower-level shell 2 using a first bolt. The number of support components can be increased or decreased according to the size of the wall panels. A fixing plate 5 is fixed to the bottom of the support components. The lower-level shell 2 is located on the front side of the wall, and the front side of the wall is provided with hooks. When installation is required, the position of the support components must be adjusted before the fixing plate 5 can be fixed to the floor slab to improve stability.

[0047] The activation of the third drive device 23 enables the first lead screw 26 to rotate. When the first lead screw 26 rotates, it can drive the support column 4 to move up and down, thereby adjusting the height of the lower housing 2 so as to support the floor slab. Specifically, the support component includes a limiting slide rail 3 extending in the vertical direction and a support column 4 that can slide up and down along the limiting slide rail 3.

[0048] A third drive device 23 (a third drive self-locking motor) is fixedly installed inside the lower housing 2. The output shaft of the third drive device 23 is fixedly equipped with a horizontal bar 24 extending in the left-right direction. (The right end of the horizontal bar 24 has a mounting slot with an opening facing right, while the left sides of adjacent lower housings 2 are each fixedly equipped with a mounting rod, which slides into the mounting slot to securely connect the adjacent horizontal bar 24 to the lower housing 2.) A second limiting strip extending in the extending direction of the horizontal bar 24 is fixedly installed on the outer side of the horizontal bar 24, allowing it to... The first linkage bevel gear 2501 can rotate, or it can slide along the extension direction of the crossbar 24, thereby enabling disassembly and installation. The crossbar 24 is connected to a first lead screw 26 extending in the vertical direction. The support column 4 is rotatably mounted on the first lead screw 26 and threadedly connected to it. When the first lead screw 26 rotates, it drives the support column 4 to move up and down along the limit slide rail 3, thereby driving the third drive device 23 to start, so that the output end of the third drive device 23 can drive the crossbar 24 to rotate.

[0049] The bottom of the lower housing 2 is provided with a movable groove that is open from top to bottom and extends in the left and right direction. The first lead screw 26 is slidably inserted into the movable groove. The right side of the lower housing 2 is provided with a detachable movable door.

[0050] A first linkage bevel gear 2501 is slidably mounted on the crossbar 24. When the wall panel requires multiple support points, the first linkage bevel gear 2501 can be slidably mounted on the crossbar 24 to improve support stability. A second linkage bevel gear 2502 is fixedly mounted on the upper end of the first lead screw 26. When the crossbar 24 rotates, it can drive the first linkage bevel gear 2501 to rotate. Since the first linkage bevel gear 2501 and the second linkage bevel gear 2502 mesh with each other, they can drive the second linkage bevel gear 2502 to rotate. When the first linkage bevel gear 2501 and the second linkage bevel gear 2502 mesh with each other, the rotation of the second linkage bevel gear 2502 can drive the first lead screw 26 to rotate. When the first lead screw 26 rotates, it can drive the support column 4 to move up and down along the limit slide rail 3 to adjust the height of the lower housing 2.

[0051] The height of the lower-level flipping mechanism is adjusted by the up-and-down lifting mechanism, and then the lower-level flipping mechanism flips the abutment plate 11 down to support the wall panel. Specifically, the rear side of the support component has a rearward-facing groove 6. The groove 6 has two lower-level flipping mechanisms spaced vertically. The groove 6 also has an up-and-down lifting mechanism extending vertically. The up-and-down lifting mechanism can adjust the height of the lower-level flipping mechanism to improve the support effect. The lower-level flipping mechanism is connected to the up-and-down lifting mechanism. The up-and-down lifting mechanism is used to drive the two lower-level flipping mechanisms to move in opposite or relative directions within the groove 6. Under the action of the up-and-down lifting mechanism, the two lower-level flipping mechanisms can move in opposite or relative directions within the groove 6.

[0052] The upper and lower lifting mechanism has two vertically spaced moving blocks 13 connected to its upper transmission.

[0053] The lower-level flipping mechanism enables the abutment plate 11 to flip, making it easy to store when flipped into the groove 6, and supporting the wall panel when flipped out of the groove 6. Specifically, the lower-level flipping mechanism includes two movable connecting blocks 43 spaced apart from each other and a rotating rod 15. Two movable slide rails 14 extending vertically are fixedly provided on the rear side of the movable blocks 13. The two movable connecting blocks 43 are slidably mounted on the movable slide rails 14. Both movable connecting blocks 43 are hinged to the abutment plate 11. During the flipping process, the abutment plate 11 can drive the movable connecting blocks 43 to move upward along the movable slide rails 14, so that the abutment plate 11 flips out of the groove 6 and is in a horizontal state.

[0054] The inner wall of the inner cavity 7 has a through hole that is open to the left and right, and the inner cavity 7, the through hole and the groove 6 are interconnected.

[0055] Two rotating rods 15 are respectively hinged to the left and right sides of the abutment plate 11. A first transmission rod 16 extending in the left and right direction is fixed between the two rotating rods 15. The first transmission rod 16 passes through the through hole and is connected to the synchronous operation mechanism. When the rotating rod 15 rotates, it drives the abutment plate 11 to flip up and down to create the groove 6. When the abutment plate 11 rotates, it drives the movable connecting block 43 to move up and down along the movable slide rail 14. When the rotating rod 15 rotates, it drives the movable connecting block 43 to move up and down along the movable slide rail 14, so that the abutment plate 11 rotates. When the first transmission rod 16 rotates, it can drive the rotating rod 15 to rotate. When the rotating rod 15 rotates, it can drive the abutment plate 11 to flip.

[0056] By setting up a synchronous operation mechanism, the two abutment plates 11 can be flipped out or retracted at the same time. Specifically, the support component assembly has an inner cavity 7 inside, and the inner cavity 7 has a synchronous operation mechanism inside. The two lower-level flipping mechanisms in the same column are respectively connected to the synchronous operation mechanism for transmission. The synchronous operation mechanism is used to drive the two lower-level flipping mechanisms in the same vertical column to flip synchronously.

[0057] The synchronous operation mechanism includes a limiting rotating rod 17 extending in the vertical direction. A first limiting strip extending in the extending direction of the limiting rotating rod 17 is fixedly provided on the outer side of the limiting rotating rod 17. The first limiting strip on the outer side of the limiting rotating rod 17 can drive the second bevel gear 802 to rotate, and can also drive the second bevel gear 802 to move up and down along the limiting rotating rod 17 during the up and down movement of the moving block 13. The bottom of the limiting rotating rod 17 is rotatably connected to the inner bottom wall of the inner cavity 7, and the first transmission rod 16 is connected to the limiting rotating rod 17 for transmission.

[0058] The top of the support column 4 is fixedly provided with a first drive device 41 (the first drive device 41 is a first drive self-locking motor) that can drive the limit rotating rod 17 to rotate. The upper end of the limit rotating rod 17 passes through the support column 4 and is connected to the first drive device 41 for transmission.

[0059] The lifting mechanism can adjust the height of the lower flipping mechanism to improve the support effect. Specifically, the lifting mechanism includes a first bidirectional lead screw 21 and a first guide rod 22 extending in the vertical direction. A second drive device 42 (the second drive device 42 is a second drive self-locking motor) is fixedly installed on the top of the support column 4. The output shaft of the second drive device 42 passes through the inner top wall of the groove 6 and is fixedly connected to the first bidirectional lead screw 21. The first bidirectional lead screw 21 and the first guide rod 22 are rotatably connected to the inner top wall and inner bottom wall of the groove 6, driving the second drive device 42 to start, so that the output end of the second drive device 42 can drive the first bidirectional lead screw 21 to rotate, which can drive the moving block 13 to move up and down along the first guide rod 22.

[0060] Both moving blocks 13 are rotatably mounted on the first bidirectional lead screw 21 and the first guide rod 22, and are threadedly connected to the first bidirectional lead screw 21. The first bidirectional lead screw 21 is used to drive the two moving blocks 13 to move in opposite or opposite directions along the first guide rod 22. When the first bidirectional lead screw 21 rotates, it can drive the moving blocks 13 to move up and down along the first guide rod 22.

[0061] A first bevel gear 801 is fixedly mounted on the end of the first transmission rod 16 away from the rotating rod 15. A second bevel gear 802 is slidably mounted on the limiting rotating rod 17. The first bevel gear 801 and the second bevel gear 802 mesh with each other. Because the first bevel gear 801 and the second bevel gear 802 mesh with each other, the second bevel gear 802 can drive the first bevel gear 801 to rotate when it rotates. Both the first transmission rod 16 and the second bevel gear 802 are rotatably mounted with L-shaped sleeves 803. The L-shaped sleeves 803 are designed to support the first bevel gear 801 and the second bevel gear 802, preventing the first bevel gear 801 and the second bevel gear 802 from tilting and getting stuck.

[0062] The lower-level flipping mechanism is equipped with a backing plate 11, and a fifth telescopic device 45 (the fifth telescopic device 45 is a fifth hydraulic telescopic rod) is fixedly installed on the backing plate 11. A hook 44 is hinged to the end face of the movable rod of the fifth telescopic device 45. The lower-level flipping mechanism is used to flip the backing plate 11 up and down to create a groove 6. The hook 44 is hooked onto the hook ring. After the backing plate 11 is flipped down, the extension of the fifth telescopic device 45 connects the hook 44 to the hook ring to support the wall panel. Then, the retraction of the fifth telescopic device 45 drives the support assembly to move until the backing plate 11 abuts against the wall panel, and the fifth telescopic device 45 stops moving.

[0063] Working principle: The specific operation is as follows:

[0064] S1, Mark out the wall panel installation positions on the floor slab to form the construction base line for wall panel installation;

[0065] S2, Place the support components at the construction foundation line for wall panel installation;

[0066] S3, hoist the wall panel and move it to the wall panel installation position;

[0067] S4, control the second drive device 42 to start, so that the output end of the second drive device 42 drives the first bidirectional lead screw 21 to rotate. When the first bidirectional lead screw 21 rotates, it can drive the two moving blocks 13 to move along the first guide rod 22 in opposite or opposite directions. When the two moving blocks 13 move to one-third of the height of the wall panel, the second drive device 42 stops moving (driving the second drive device 42 to start, so that the output end of the second drive device 42 can drive the first bidirectional lead screw 21 to rotate, and can drive the moving blocks 13 to move up and down along the first guide rod 22. When the first bidirectional lead screw 21 rotates, it can drive the moving blocks 13 to move up and down along the first guide rod 22, adjusting the height of the two moving blocks 13).

[0068] S5, drive the first drive device 41 to start, so that the output shaft of the first drive device 41 drives the limiting rotating rod 17 to rotate. When the limiting rotating rod 17 rotates, it can drive the first transmission rod 16 to rotate, so that the abutment plate 11 flips up and down out of the groove 6 to a horizontal state (drive the first drive device 41 to start, so that the output end of the first drive device 41 can drive the limiting rotating rod 17 to rotate. When the limiting rotating rod 17 rotates, it can drive the second bevel gear 802 to rotate. Since the first bevel gear 801 and the second bevel gear 802 mesh with each other, the second bevel gear 802 can drive the first bevel gear 801 to rotate when it rotates. The first bevel gear 801 can drive the first transmission rod 16 to rotate when it rotates. The first transmission rod 16 can drive the rotating rod 15 to rotate when it rotates. When the rotating rod 15 rotates, it can drive the abutment plate 11 to flip. During the flipping process, the abutment plate 11 can drive the movable connecting block 43 to move upward along the movable slide rail 14, so that the abutment plate 11 flips out of the groove 6).

[0069] S6, control the fifth telescopic device 45 to extend, hook the hook 44 onto the hook ring of the wall panel, and then drive the support component to move through the retraction of the fifth telescopic device 45 until the abutment plate 11 abuts against the wall panel, and the fifth telescopic device 45 stops moving.

[0070] S7, drive the third drive device 23, so that the output shaft of the third drive device 23 drives the first lead screw 26 to rotate. When the first lead screw 26 rotates, it drives the lower housing 2 to move upward. When the top of the lower housing 2 moves to be flush with the top of the wall panel, it stops (drive the third drive device 23 to start, so that the output end of the third drive device 23 can drive the crossbar 24 to rotate. When the crossbar 24 rotates, it can drive the first linkage bevel gear 2501 to rotate. Since the first linkage bevel gear 2501 and the second linkage bevel gear 2502 mesh with each other, it can drive the second linkage bevel gear 2502 to rotate. When the second linkage bevel gear 2502 rotates, it can drive the first lead screw 26 to rotate. When the first lead screw 26 rotates, it can drive the support column 4 to move up and down along the limit slide rail 3 in order to adjust the height of the lower housing 2).

[0071] S8, repeat S1-S8 operations to make multiple lower-level shells 2 plugged in, so that adjacent crossbars 24 are plugged together until the front wall panel construction is completed (adjacent crossbars 24 are plugged into the corresponding crossbar 24 slots, while lower-level shells 2 are plugged into adjacent lower-level shells 2).

[0072] S9, fix the fixing plate 5 to the floor slab.
