[0002] With the continuous development of building industrialization and the concept of green buildings, prefabricated steel structure buildings have gradually become the mainstream trend in the construction industry due to their advantages such as high efficiency, environmental protection, and recyclability. In prefabricated steel structure buildings, as an important enclosure structure, the installation efficiency and connection quality of wall panels have a crucial impact on the construction progress and service performance of the entire building.

[0003] At present, the connection methods of prefabricated steel frame wall panels mainly include welding, bolt connection, snap connection, etc. Although welding connection is firm, the construction process is complex, requiring professional welding equipment and skilled welders, and a large amount of heat and fumes are generated during the welding process, which is unfavorable to the construction environment and the health of personnel. For snap connection, at least two workers are required to manually lift the relatively large-area wall panel and then move the wall panel to a parallel state for splicing with the side of the rigid frame. This not only has a greater construction difficulty but also is accompanied by certain safety risks.

[0018] Please refer to Figure 1 and Figure 3 , the present invention provides a technical solution: a quick connection device for an assembled steel skeleton wall panel, including a wall body 1. A plurality of horizontal skeletons 2 and vertical skeletons 3 are provided on the side of the wall body 1. The side of the horizontal skeleton 2 is fixedly connected to the wall surface through expansion bolts for leveling the surface of the wall body 1 to ensure the flatness during the installation of the wall panel.

Therefore, the assembled wall panel can be vertically inserted downward between the two vertical skeletons 3 and then installed on one side of the wall body 1; the above is the prior art, so it will not be elaborated further.

[0019] Please refer to Figures 1-4 , in this solution, a base 4 is provided on one side of the wall body 1. A plurality of universal wheels 37 are provided below the base 4 and fixedly connected thereto. The universal wheels 37 are used to move the base 4, so that the base 4 can quickly carry out the installation work of the wall panel in different areas. A sliding seat 5 is provided above the base 4. A fixing block 6 is provided at the bottom of the sliding seat 5 and fixedly connected thereto. An electric push rod 31 is provided on one side of the sliding seat 5 and fixedly connected thereto. The electric push rod 31 is fixedly connected to the base 4 through a fixing frame. The fixing block 6 is slidably connected to the base 4. The sliding seat 5 slides relative to the base 4 through the fixing block 6. The moving power source of the sliding seat 5 is provided by the electric push rod 31, and the distance of the displacement of the sliding seat 5 can be freely adjusted by the staff.

[0020] The inside of the sliding seat 5 is of a cavity structure. A motor 7 is provided inside the sliding seat 5. The bottom of the motor 7 is fixedly connected to the sliding seat 5. A screw rod 8 is provided above the motor 7. The rotating shaft of the motor 7 is connected to the screw rod 8 through a coupling. A moving block 9 is provided on the outer wall of the screw rod 8 and meshed therewith for driving. After the motor 7 drives the screw rod 8 to rotate, the moving block 9 will move up or down due to the meshing effect with the screw rod 8. An outer rod 10 is provided on the side of the moving block 9 and fixedly connected thereto. An inner rod 11 is provided inside the outer rod 10 and slidably connected thereto. An insertion rod 35 is provided inside the outer rod 10.

A plurality of insertion holes 36 for inserting the insertion rod 35 are equidistantly provided inside the inner rod 11. Through the settings of the electric push rod 31, the inner rod 11 and the outer rod 10, the staff can freely choose to insert the insertion rod 35 into different insertion holes 36, thereby controlling the extending distance of the inner rod 11, and at the same time driving the electric push rod 31 to control the sliding distance of the sliding seat 5, so that this device is suitable for the installation of wall panels of different specifications and improves the applicability of this device.

[0021] Further, a rotating block 12 is provided inside the inner rod 11. A U-shaped frame 13 is provided at the end of the rotating block 12 and fixedly connected thereto. A connecting shaft 14 is provided inside the rotating block 12 and fixedly connected thereto. The connecting shaft 14 passes through the inner rod 11 and is rotatably connected thereto. An air pump 15 is provided above the U-shaped frame 13 and fixedly connected thereto. Two suction pipes 16 are provided at the suction port above the air pump 15 and are interconnected therewith. A connecting cylinder 17 is provided at the end of the suction pipe 16 and is interconnected therewith. A suction cup 18 is provided at the end of the connecting cylinder 17 and fixedly connected thereto. A connecting plate 19 is provided on the outer wall of the connecting cylinder 17 and fixedly connected thereto. The side of the connecting plate 19 is fixedly connected to the end of the U-shaped frame 13. A camera 34 is provided below the U-shaped frame 13 and fixedly connected thereto. The camera 34 is electrically connected to an external controller. The video collected by the camera 34 can be synchronously displayed on the display screen of the external controller in real time; When the air pump 15 works, it will cause the suction cup 18 to generate suction to adsorb the wall panel. Then, through the meshing relationship between the screw rod 8 and the moving block 9, the suction cup 18 and the wall panel are driven to move vertically up and down, and the wall panel is quickly connected between the two vertical skeletons 3. The staff can observe the alignment of the two ends of the wall panel with the protruding shapes on both sides of the vertical skeleton 3 through the real-time video collected by the camera 34, thereby assisting the wall panel to be more smoothly installed between two adjacent vertical skeletons 3 and improving the installation accuracy.

[0022] Further, please refer to Figures 4-7 , a bent rod 20 is provided on one side of the sliding seat 5. The bent rod 20 includes a connecting portion 21 and a bent groove portion 22. The end of the bent rod 20 is fixedly connected to the outer wall of the sliding seat 5. A connecting piece 23 is provided on the side of the U-shaped frame 13 and fixedly connected thereto. A limiting column 24 is provided on one side of the connecting piece 23 and fixedly connected thereto. The width of the groove body of the bent groove portion 22 is equal to the diameter of the limiting column 24. A bearing plate 25 is provided above the base 4. A hydraulic push rod 26 is provided at the bottom of the bearing plate 25 and fixedly connected thereto. The bottom of the hydraulic push rod 26 is fixedly connected to the base 4.

[0023] When the limiting column 24 slides to the bottom end of the bent groove portion 22, the connecting plate 19 is parallel to the base 4, and the adsorption areas of the two suction cups 18 are in contact with the surface of the wall panel above the bearing plate 25. A slider 27 is provided inside the connecting shaft 14 and is slidably connected thereto. A fixed box 28 is provided on the outer wall of the slider 27 and is slidably connected thereto. The side of the fixed box 28 is fixedly connected to the inner rod 11. A spring 29 is provided inside the fixed box 28. The two ends of the spring 29 are respectively fixedly connected to the slider 27 and the fixed box 28. A connecting pipe 30 is provided at the end of the fixed box 28 and is interconnected therewith. The other end of the connecting pipe 30 is interconnected with the other suction port of the air pump 15. When the air pump 15 sucks air into the fixed box 28 through the connecting pipe 30, the slider 27 will be separated from the inside of the connecting shaft 14 due to negative pressure, and thus the U-shaped frame 13 and the inner rod 11 can rotate freely.

[0024] In addition, two vertical rods 32 are provided at the bottom of the connecting plate 19. The ends of the vertical rods 32 are fixedly connected to the connecting plate 19. A rubber strip 33 is provided at the bottom end of the vertical rod 32 and fixedly connected thereto. The rubber strip 33 is in contact with the side of the wall panel. During the installation process, the rubber strip 33 can play a buffering role for the extrusion of two adjacent wall panels. The air pump 15, the hydraulic cylinder, the electric push rod 31 and the motor 7 are all controlled by an external controller and can be automatically started and stopped after setting the program flow. After the hydraulic cylinder is preset through the program, during the installation process, the height of the wall panels accumulated on the bearing plate 25 can be always maintained at the same height, ensuring that the suction cup 18 can effectively adsorb the next wall panel after flipping.

[0025] Please refer to Figures 1-8 , the working process of this device is as follows: Vertical installation process In the state where the slider 27 is inserted into the inside of the connecting shaft 14, the rotation state of the connecting shaft 14 is restricted. Therefore, the outer rod 10, the inner rod 11 and the U-shaped frame 13 are all in a state parallel to the base 4. At this time, the air pump 15 can be used to suck the air suction pipe 16 to make the suction cup 18 adsorb the wall panel. Then, the motor 7 is started to drive the screw rod 8 to rotate. The rotating screw rod 8 will drive the moving block 9 inside the sliding seat 5 to rise. The moving block 9 will drive the outer rod 10, the inner rod 11, the U-shaped frame 13 and the connecting plate 19 to rise synchronously until the moving block 9 is displaced to the uppermost end of the sliding seat 5. At this time, the lowermost end of the adsorbed wall panel is already higher than the highest point of the vertical skeleton 3. Then, the electric push rod 31 is used to push the sliding seat 5 to displace until the slot openings at both ends of the wall panel are aligned with the shape of the vertical skeleton 3. Then, the motor 7 is driven to reverse to make the moving block 9 drive the wall panel to descend vertically until the wall panel contacts the previously installed wall panel, completing the rapid connection of a single wall panel. Compared with the prior art, it is not necessary to manually lift the wall panel and then splice it with the side of the vertical skeleton 3, improving the installation efficiency and reducing the construction difficulty and safety risk.

[0026] Flip-type adsorption of wall panels When installing the lowest wall panel, as the U-shaped frame 13 moves downward, the limit post 24 will cross the curved groove part 22 and displace the moving block 9 to the lowermost end of the sliding seat 5. At this time, the controller is used to make the air pump 15 lose the adsorption effect on the suction cup 18, and then the wall panel already between the two vertical skeletons 3 is manually pushed downward and installed.

[0027] When installing the second wall panel, the remaining wall panels can be pre-placed on the bearing plate 25, and then the above-mentioned vertical transportation action is repeated for the second wall panel. When the bottom of the rubber strip 33 comes into contact with the side of the first wall panel, the suction effect of the air pump 15 is turned off, and the electric push rod 31 is used to drive the sliding seat 5 and the suction cup 18 to displace, and at the same time, the rubber strip 33 is withdrawn from between the two wall panels.

[0028] Immediately afterwards, the motor 7 is used to drive the moving block 9 to drive the U-shaped frame 13 to move upward until the limit post 24 rises above the top of the bent groove part 22. Then, the electric push rod 31 is used to drive the limit post 24 to displace so that it is aligned with the port of the bent groove part 22. At this time, the motor 7 is reversed, and at the same time, the air pump 15 sucks the inside of the fixed box 28 through the connecting pipe 30, so that the slider 27 disengages from the inside of the connecting shaft 14, and then the limit post 24 slides inside the bent groove part 22 until the limit post 24 slides to the bottom of the bent groove part 22. At this time, the connecting plate 19 and the suction cup 18 are turned over, and the bottom of the suction cup 18 comes into contact with the surface of the wall panel above the bearing plate 25. At this time, the air pump 15 is started again to make the suction cup 18 have suction again, and the motor 7 is used to drive the suction cup 18 to move upward. The upward movement will cause the U-shaped frame 13 to rotate back to be parallel to the base 4, and the elastic force of the spring 29 will drive the slider 27 to insert into the notch of the connecting shaft 14 again, so that the rotation of the connecting shaft 14 is limited again. Finally, the third wall panel repeats the vertical conveying and installation work.

[0029] After the installation of the third wall panel is completed, the limit post 24 can be directly driven to be aligned with the end of the bent groove part 22 in the vertical direction, and then the motor 7 is directly used to drive the suction cup 18 to perform a flipping motion, adsorb the fourth wall panel and complete its installation.

[0030] The overall installation process combines vertical conveying and installation with flipping and feeding installation, and can be automatically controlled by an operator through a controller. The automatic installation and feeding of multiple wall panels are realized, greatly improving the installation efficiency of prefabricated wall panels and reducing the construction difficulty and potential safety hazards.
