Description

Technical Field

[0001] This invention relates to the field of prefabricated building construction technology, specifically to a precision docking device for prefabricated building components in housing construction. Background Technology

[0002] Prefabricated buildings, with their advantages of short construction cycle, low environmental pollution, high degree of industrialization, and high resource utilization, have become the core development direction for the transformation and upgrading of my country's housing construction industry. The core process of prefabricated building construction is the hoisting and docking assembly of prefabricated components. Common components include prefabricated wall panels, prefabricated beams and columns, composite floor slabs, and prefabricated stairs. The docking accuracy of components directly determines the overall structural stability, waterproof and seepage-proof performance, and construction acceptance rate of the building.

[0003] Currently, the common construction method for connecting prefabricated components in China is "lifting equipment hoisting + manual visual calibration". This method has several industry pain points: First, conventional lifting equipment does not have a load-bearing plate structure at the bottom for lifting and transfer, so it cannot provide bottom load protection, resulting in a low safety factor during the lifting and transfer process. Second, existing dedicated docking auxiliary equipment has a single structural function, mostly only having unidirectional displacement adjustment function, and cannot simultaneously complete multi-axis displacement and angle correction. Moreover, it has poor adaptability and can only be used for single-type components, which cannot meet the assembly needs of multi-specification components on the construction site. Therefore, we propose a precision docking equipment for prefabricated components in housing construction to solve the above-mentioned problems. Summary of the Invention

The output end of the Z-axis servo motor 15 is connected to a Z-axis lead screw 16. A Z-axis slide 17 is threaded onto the outer side of the Z-axis lead screw 16. The Z-axis slide 17 is used to control the vertical lifting and lowering of the component along the Z-axis. The angle fine-tuning assembly includes a rotary motor a19 mounted on the lower end of the Z-axis slide 17. The output end of the rotary motor a19 is connected to a mounting plate 20 to adjust the pitch angle of the component. A rotary motor b21 is mounted on the upper end of the mounting plate 20. The output end of the rotary motor b21 is connected to a fixing frame 22 to adjust the horizontal rotation of the component. The adaptive clamping mechanism is fixedly connected to the action output end of the three-dimensional adjustment mechanism and is used to clamp and fix assembled components of different specifications. Furthermore, the adaptive clamping mechanism includes a fixed frame 22, a bidirectional lead screw 24, a clamping plate 26, and an adjustable servo motor 23. The adjustable servo motor 23 is installed at one end of the fixed frame 22, and the output end of the adjustable servo motor 23 is connected to the bidirectional lead screw 24. The outer side of the bidirectional lead screw 24 is threaded to a sliding plate 25, and the lower end of the sliding plate 25 is connected to the clamping plate 26. The opposite surfaces of the clamping plate 26 are each connected to an elastic buffer pad 39, and the elastic buffer pad 39 is provided with anti-slip teeth 18. The bottom support and protection component is installed at the lower end of the adaptive clamping mechanism to provide bottom support and protection for the hoisted components; Furthermore, the bottom bearing protection assembly includes a spring a27 connected inside the clamping plate 26, a movable plate 28 is installed at the lower end of the spring a27, a mounting base 29 is installed at the lower end of the movable plate 28, a drive motor 30 is installed on one side of the mounting base 29, a rotating shaft 31 is connected to the output end of the drive motor 30, and a bearing plate 32 is installed on the outer side of the rotating shaft 31. Furthermore, a spring b34 and a fixing plate 37 are connected to the side of the mounting base 29 away from the drive motor 30. A positioning rod 35 is connected to one end of the spring b34. An electromagnet a36 is installed on the upper end of the positioning rod 35. An electromagnet b38 is installed on the side of the fixing plate 37 opposite to the electromagnet a36. Furthermore, the lower end of the positioning rod 35 has a smooth arc-shaped structure, and the positioning rod 35 engages with the positioning hole 33 opened on the outer wall of the rotating shaft 31. Furthermore, the positions of electromagnets a36 and b38 are correspondingly distributed, and electromagnets a36 and b38 are opposite pole magnets. Furthermore, the movable plate 28 has a "T" shaped structure and slides through the clamping plate 26; Specifically, when using the prefabricated component precision docking equipment for house construction, workers pass the hoisting wire rope through the hoisting connecting lug 4 and connect it to the truck crane to complete the equipment hoisting. The clamping plates 26 are located on both sides of the prefabricated wall panel and gradually become flush with the bottom of the prefabricated wall panel. At this time, the mounting base 29 is subjected to force and moves upward, causing the mounting base 29 to control the moving plate 28 to move upward. The moving plate 28 compresses and stores force on the spring a27, so that the bottom of the mounting base 29 is flush with the bottom of the clamping plate 26. The adjusting servo motor 23 is started, driving the bidirectional lead screw 24 to rotate. The two sets of clamping plates 26 move synchronously towards each other, clamping the upper prefabricated wall panel to be assembled. The elastic buffer pads 39 and anti-slip teeth 18 set on the opposite sides of the clamping plates 26 can increase the friction between the clamping plates 26 and the prefabricated wall panel. The friction force is increased to improve the clamping degree. After clamping, the rectangular base 1 is lifted. At this time, the clamping component is away from the ground. The stored spring a27 controls the moving plate 28 to move down and reset, thereby controlling the mounting base 29 to move down and reset, so that the lower end of the mounting base 29 moves down to below the lower end of the precast wall panel. After lifting a short distance, the drive motor 30 can be started to control the rotating shaft 31 to rotate. Rotate the rotating shaft 31 to the horizontal position. At this time, the position of the positioning hole 33 corresponds to the position of the positioning rod 35. The stored spring b34 controls the positioning rod 35 to move down and reset, so that the positioning rod 35 is inserted into the positioning hole 33. The horizontal bearing plate 32 is locked, and the bearing plate 32 is used to provide bottom bearing protection for the lifted precast wall panel. When the equipment is hoisted to the assembly position, electromagnets a36 and b38 are powered on. The electromagnets with opposite poles attract each other, driving the positioning rod 35 upwards. The positioning rod 35 stretches and stores force on the spring b34, moving the positioning rod 35 out of the positioning hole 33 and releasing the lock on the rotating shaft 31. The drive motor 30 then controls the rotating shaft 31 to drive the bearing plate 32 to rotate in the reverse direction, releasing the load on the bottom of the precast wall panel. Next, the truck crane is slowly lowered to the upper wall panel, gradually aligning it with the lower wall panel. This can be achieved by driving the X-axis servo motor 10 to control the rotation of the X-axis lead screw 7, thereby controlling the X-axis slider 8 to slide on the X-axis guide rail 6, realizing lateral adjustment. Following the above steps, the Y-axis servo motor 1... 1. The Z-axis servo motor 15 enables longitudinal and vertical adjustment and drives the rotary motor a19 to rotate the mounting plate 20, allowing for pitch angle adjustment. It also drives the rotary motor b21 to rotate the fixing frame 22, allowing for rotation adjustment. This corrects the position of the precast wall panel. After correction, precise docking of components can be performed. After docking, once the wall panel's posture is confirmed to be stable and without offset or misalignment, the servo motor 23 is controlled to reverse, and the bidirectional lead screw 24 is controlled to move the clamping plate 26 in the opposite direction, releasing the precast wall panel. The hoisting equipment is then used to remove the equipment from the construction position, completing a single precise docking operation of the precast wall panel.
