Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering, and in particular to a precision splicing construction device for prefabricated building components. Background Technology

[0002] In modern construction engineering, prefabricated construction has been widely used as an efficient and environmentally friendly construction method. Prefabricated construction uses prefabricated components in factories and assembles them on site, which can significantly shorten the construction period and effectively reduce environmental pollution and noise interference at the construction site.

[0003] Prefabricated building construction typically relies on hoisting equipment (such as tower cranes and truck cranes) to transport prefabricated components to designated locations. Construction workers then manually adjust the components to achieve precise alignment. However, communication between hoisting equipment operators and on-site supervisors depends on walkie-talkies, hand signals, or verbal instructions to complete critical actions such as lifting, moving, positioning, and installing components. Due to the complex on-site environment and severe noise interference, coordination efficiency is easily reduced, causing delays in construction progress. Furthermore, precise positioning is difficult to achieve, affecting the final assembly quality.

[0004] Therefore, it is necessary to design a precision splicing construction device for prefabricated building components. Utility Model Content

[0005] In order to overcome the shortcomings of existing prefabricated building splicing, which relies on the coordination and cooperation between workers, resulting in low construction efficiency and poor positioning accuracy, this utility model provides a precise splicing construction device for prefabricated building components.

[0007] As a preferred technical solution of this utility model, the clamping and positioning mechanism includes a load-bearing column, an electric guide rail, clamping plates, a laser positioning device, a rack, a gear, and a motor. The load-bearing column is slidably connected to the middle of the connecting box, and an electric guide rail is installed at the lower part of the load-bearing column.

Detailed Implementation

[0020] Example: A precision splicing construction device for prefabricated building components, such as... Figures 1-4 As shown, the device includes a base 1, a controller 2, an electric turntable 3, an electric push rod 4, a telescopic rod 401, a connecting box 501, an angle leveling mechanism, a vision camera 6, and a clamping and positioning mechanism. The controller 2 is installed on the front left side of the base 1, the electric turntable 3 is installed on the top of the base 1, the electric push rod 4 is installed above the rotating disc of the electric turntable 3, the telescopic rod 401 is installed inside the electric push rod 4, the connecting box 501 is installed on the upper part of the telescopic rod 401, the angle leveling mechanism is installed between the lower part of the connecting box 501 and the top of the telescopic rod 401, the vision camera 6 is installed on both the front and rear sides of the electric push rod 4, and the clamping and positioning mechanism is installed on the connecting box 501. The controller 2 is electrically connected to the electric turntable 3, the electric push rod 4, and the vision camera 6.

[0021] like Figures 1-4 As shown, the clamping and positioning mechanism includes a load-bearing column 5, an electric guide rail 7, clamping plates 8, a laser positioning device 9, a rack 10, a gear 11, and a motor 12. The load-bearing column 5 is slidably connected to the middle of the connecting box 501. The electric guide rail 7 is installed at the lower part of the load-bearing column 5. Two symmetrical clamping plates 8 are slidably connected to the rear side of the electric guide rail 7. Laser positioning devices 9 are installed on opposite sides of the clamping plates 8. The emitting end of the laser positioning device 9 faces directly downwards, and the laser positioning device 9 uses a green laser. Green laser has relatively high brightness under sunlight, and its visibility and contrast on the concrete surface are also relatively clear. A rack 10 is provided on the upper part of the load-bearing column 5. A gear 11 is rotatably connected to the upper part of the connecting box 501. The gear 11 is located directly above the rack 10 and meshes with it. A motor 12 is installed on the right side of the outside of the connecting box 501. The shaft of the motor 12 is connected to the gear 11. The controller 2 is electrically connected to the electric guide rail 7, the laser positioning device 9, and the motor 12.

[0022] like Figure 2 , Figure 3 and Figure 4 As shown, the angle leveling mechanism includes an angle sensor 13 and an electric leveler 14. An angle sensor 13 is installed on the right side of the connecting box 501, and an electric leveler 14 is installed between the lower part of the connecting box 501 and the top of the telescopic rod 401. The leveling support platform of the electric leveler 14 is connected to the bottom of the connecting box 501, and both the angle sensor 13 and the electric leveler 14 are electrically connected to the controller 2.

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, it also includes casters 101 and hooks 102. Casters 101 are installed on the front, back and left and right sides of the lower part of the base 1. Hooks 102 are slidably provided on the front side of the electric guide rail 7. Casters 101 enable flexible movement of the equipment, while hooks 102 expand the compatibility of traditional hoisting equipment and effectively address different construction scenarios and task requirements.

[0024] In actual use, construction personnel first need to move the equipment to the target work area and use the casters 101 for flexible positioning. Then, the electric turntable 3 is activated by the controller 2 to rotate the entire device toward the precast component, ensuring that the clamping and positioning mechanism is aligned with the component to be assembled. Next, the construction personnel need to control the electric push rod 4 through the controller 2, causing the telescopic rod 401 to slide up and down inside, thereby adjusting the height of the connecting box 501 and the clamping and positioning mechanism to a suitable position. On this basis, the motor 12 can be started to drive the gear 11 to rotate clockwise or counterclockwise, pushing the meshing rack 10 to move back and forth along the X-axis, thereby causing the load-bearing column 5 to produce lateral displacement, achieving further fine adjustment of the horizontal position of the clamping point.

[0025] During the process, the vision camera 6 captures real-time images of the construction site and transmits them to the controller 2. The system identifies and calibrates the component position based on the image information, assisting operators in completing the initial docking preparation. When the clamping and positioning mechanism approaches the target component, the laser positioning device 9 emits a green laser beam projected onto the ground or component surface to indicate the precise position of the clamping point, providing an intuitive positioning reference for operators or the control system. After confirming that the positioning is correct, the controller 2 controls the electric guide rail 7 to run, driving the two clamping plates 8 to close synchronously to stably clamp the precast component. After clamping is completed, the electric push rod 4 moves again to lift the component to the required height. At the same time, according to the splicing requirements, the electric turntable 3 adjusts the overall angle of the device, and the motor 12 controls the distance in the X-axis direction to gradually align the component to the target splicing posture.

[0026] Throughout the transportation and adjustment process, the tilt sensor 13 continuously monitors the attitude changes of the connecting box 501 and feeds the data back to the controller 2. If the connecting box 501 is detected to be tilted, the electric leveler 14 will automatically intervene and quickly adjust the connecting box 501 to a horizontal state, ensuring that the clamped components remain stable in the air and avoiding splicing deviations or safety hazards caused by tilting. Finally, the device smoothly transports the prefabricated components to the designated splicing position, and through the coordinated control of the electric push rod 4 and the electric guide rail 7, performs longitudinal and lateral micro-adjustments on the clamping points to achieve millimeter-level precision docking operations. After splicing is completed, the controller 2 issues a command, and the clamping plate 8 releases the components, allowing them to be smoothly installed in place, completing the entire splicing process.
