Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and specifically relates to a quick fixing device for prefabricated wall panels. Background Technology

[0002] In prefabricated buildings, the installation of prefabricated wall panels typically relies on manual labor or a wall panel robot to move them to the designated position, followed by manual fixing of the wall panels to the building structure. Currently, commonly used fixing methods include pipe clamp fixing and triangular plate fixing: pipe clamp fixing involves manually fixing pipe clamps to the ends of the wall panels and then using a nail gun to secure the metal plates of the pipe clamps to the building structure; triangular plate fixing involves manually positioning the triangular plates and completing the connection.

[0003] The above-mentioned fixing method has significant drawbacks: 1. High dependence on manual labor: The fixing process requires manual determination of the installation position and operation of the nail gun, which is not only time-consuming and labor-intensive, but also prone to insufficient fixing accuracy due to human operation error; 2. High safety risks: Some precast wall panels are quite high, and fixed operations require working at heights, posing safety hazards such as falls and falling tools to operators; 3. Low efficiency: The manual operation process is cumbersome and cannot be coordinated with the automated operation of the wall panel installation robot, which restricts the overall construction progress.

[0004] Therefore, there is an urgent need for a device that can achieve automated fixing, improve construction efficiency, and reduce safety risks. Utility Model Content

[0005] The purpose of this utility model is to provide a quick fixing device for prefabricated wall panels, which can be mounted on a wall panel installation robot to achieve automatic positioning, pressing and fixing of wall panel connectors to the building structure, reduce manual operation processes and improve construction efficiency and safety.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A precast wall panel quick-fixing device includes a main groove plate, a secondary groove assembly, two excitation devices, and a drive assembly. The secondary groove assembly includes an upper secondary groove plate and a lower secondary groove plate slidably installed inside the main groove plate. The upper end of the upper secondary groove plate and the lower end of the lower secondary groove plate are each provided with a secondary groove cover plate. The secondary groove cover plate is used to install wall panel connectors. The secondary groove cover plate is also provided with a wall panel sensor and an excitation hole. The wall panel sensor is used to detect the upper or lower end of the precast wall panel. The two excitation devices are respectively fixed to the upper part of the upper secondary groove plate and the lower part of the lower secondary groove plate. The excitation column and the excitation hole of the excitation device are located on the same straight line. The excitation device is used to push fasteners from the excitation hole into the wall panel connectors and the building structure. The drive assembly is used to drive the upper and lower secondary groove plates to slide upwards or downwards.

[0007] To improve the accuracy and stability of the movement distance control of the upper and lower auxiliary slot plates, the drive assembly includes an upper drive motor and a lower drive motor. The output shafts of the upper and lower drive motors are equipped with threaded rods, and ball sliders are provided on the threaded rods. The ball sliders are fixed inside the upper or lower auxiliary slot plates. The upper and lower drive motors can drive the corresponding threaded rods to rotate, causing the ball sliders to move up or down along the threaded rods.

[0008] To further improve the movement stability of the upper and lower auxiliary slot plates, guide rails are provided on both the left and right sides inside the main slot plate, and sliders are provided on both the left and right sides of the upper and lower auxiliary slot plates, with the sliders slidably connected to the guide rails corresponding to their positions.

[0009] To facilitate the installation of the drive components, the upper and lower ends of the main slot plate are provided with main slot cover plates, and a fixing plate is provided inside the main slot plate. The fixing plate is located on the center line of the main slot plate, and support plates are provided above and below the fixing plate. The upper drive motor and the lower drive motor are respectively installed on the top and bottom surfaces of the fixing plate. One end of the threaded rod is rotatably connected to the support plate, and the other end of the threaded rod is rotatably connected to the main slot cover plate.

[0010] To further automate the fixing of prefabricated wall panels to the building structure, the wall panel sensors, upper drive motor, lower drive motor, and excitation device can be connected to the control system of the wall panel installation robot.

[0011] To facilitate the upward or downward movement of the secondary slot assembly, slots are provided on the two main slot cover plates, and the two secondary slot cover plates are respectively inserted into the slots of the two main slot cover plates.

[0012] To facilitate the installation and fixing of the device, the main slot plate is provided with a connecting plate, and the connecting plate is provided with multiple connectors for mounting the connecting plate on the wall panel installation robot.

[0013] Compared with the prior art, the present invention has the following beneficial technical effects: This invention uses a wall panel sensor on the sub-groove cover plate to automatically detect the end of the precast wall panel, a drive component to precisely control the sliding of the upper and lower sub-groove plates, and an excitation device to automatically push fasteners, replacing manual positioning and operation, greatly reducing reliance on manual labor, reducing human error, and improving fixing accuracy.

[0014] This utility model can be mounted on a wall panel installation robot via a connecting plate. All operations are completed remotely by the robot control system, eliminating the need for manual high-altitude work and completely avoiding safety risks such as falls and tool drops, thus complying with the safety specifications for prefabricated building construction.

[0015] The core components of this invention can be connected to the control system of a wall panel installation robot, enabling synchronous connection with the robot's wall panel handling and positioning actions. This shortens the fixing time for a single wall panel and significantly improves the overall construction progress. Furthermore, the guide rail of the main channel plate and the sliders of the upper and lower sub-channel plates form a guiding fit. Combined with the precise drive of the threaded rod and ball slider, it prevents the upper and lower sub-channel plates from shifting, ensuring precise pressing of the wall panel connectors, guaranteeing a long-lasting and stable fixing effect, and improving installation quality.

[0016] This utility model, by setting standardized connectors on the connecting plate, can be adapted to most wall panel installation robots. Furthermore, the extension distance of the upper and lower auxiliary groove plates can be flexibly set through the control system of the wall panel installation robot to adapt to prefabricated wall panels of different specifications. It is not only convenient to install and operate, but also has good versatility, effectively reducing the reuse cost of fixing devices. Attached Figure Description

Detailed Implementation

[0019] The following detailed description illustrates the specific implementation method: Example

[0020] like Figure 1-6 As shown, a precast wall panel quick fixing device includes a main groove plate 1, a secondary groove assembly 2, two excitation devices 3, and a drive assembly 4.

[0021] The main slot plate 1 has guide rails 11 fixed on both the left and right sides inside. The secondary slot assembly 2 includes an upper secondary slot plate 21 and a lower secondary slot plate 22. Slider 23 is fixed on both the left and right sides of the upper secondary slot plate 21 and the lower secondary slot plate 22. The slider 23 is slidably connected to the guide rail 11 on the left or right side of the main slot plate 1.

[0022] Main groove plate 1 has a main groove cover plate 12 fixed at both the upper and lower ends. The main groove cover plate 12 has a slot 121 formed on it. The upper end of the upper sub-groove plate 21 and the lower end of the lower sub-groove plate 22 are both fixed with sub-groove cover plates 24. The two sub-groove cover plates 24 are respectively inserted into the two main groove cover plates 12. The sub-groove cover plates 24 are used to install wall panel connectors 151. The sub-groove cover plates 24 are also provided with wall panel sensors 241 and excitation holes 242. The wall panel sensors 241 are used to detect the upper or lower end of the precast wall panel.

[0023] Two excitation devices 3 are fixed to the upper part of the upper auxiliary slot plate 21 and the lower part of the lower auxiliary slot plate 22 respectively. The excitation column of the excitation device 3 and the excitation hole 242 are located on the same straight line. The excitation device 3 is used to push the fastener from the excitation hole 242 into the wall panel connector 151 and the building structure.

[0024] A fixing plate 13 is welded inside the main slot plate 1. The fixing plate 13 is located on the center line of the main slot plate 1. Support plates 14 are fixed above and below the fixing plate 13. The drive assembly 4 is used to drive the upper sub-slot plate 21 and the lower sub-slot plate 22 to slide up or down. The drive assembly 4 includes an upper drive motor 41 and a lower drive motor 42. The upper drive motor 41 and the lower drive motor 42 are respectively installed on the top and bottom surfaces of the fixing plate 13. Threaded rods 43 are fixedly connected to the output shafts of the upper drive motor 41 and the lower drive motor 42. One end of the threaded rod 43 is rotatably connected to the support plate 14, and the other end of the threaded rod 43 is driveably connected to the main slot cover plate 12. Ball sliders 25 are fixed inside the upper sub-slot plate 21 and the lower sub-slot plate 22. The two ball sliders 25 are respectively connected to the two threaded rods 43. The upper drive motor 41 and the lower drive motor 42 can drive the corresponding threaded rods 43 to rotate, so that the ball sliders 25 move up or down along the threaded rods 43.

[0025] A connecting plate 15 is welded to the back of the main trough cover plate 12. The connecting plate 15 is provided with a plurality of connectors 151 for mounting the connecting plate 15 on the wall panel installation robot. In this embodiment, the connectors 151 are M8 bolts and nuts.

[0026] The precast wall panel rapid fixing device in this embodiment is mounted on a wall panel installation robot. Utilizing wall panel sensors, drive components, and a triggering device, it automates the entire "detection-movement-fixing" process, significantly reducing reliance on manual labor and improving fixing accuracy. The entire process eliminates the need for manual high-altitude operations, completely avoiding safety hazards. Deep integration with the robot control system allows for simultaneous wall panel handling and positioning, significantly improving construction efficiency. Guide rails, slider guidance, and precise drive via threaded rods and ball bearing sliders ensure a stable and reliable fixing structure. Furthermore, standardized connectors enable convenient mounting, flexibly adapting to different specifications of precast wall panels and wall panel installation robots, reducing equipment reuse costs.

[0027] The specific implementation is as follows: 1. Initial state check The main slot cover plate 12 and the secondary slot cover plate 24 are in the closed state by default. The ball block slider 25 is in the end of the threaded rod 43 near the upper drive motor 41 or the lower drive motor 42 by default. The wall plate sensor 241, the upper drive motor 41, the lower drive motor 42 and the excitation device 3 are all in the closed state. There are no particulate impurities or foreign objects that hinder the movement inside the main slot plate 1, the upper secondary slot plate 21 and the lower secondary slot plate 22 (which can be observed through the side opening of the main slot plate 1).

[0028] 2. Equipment mounting and circuit connection (compatible with wall panel installation robot) Align the connector 151 (i.e. M8 bolt post) on the back of the main channel plate 1 with the mounting hole of the robot on the wall panel, and tighten the nut to complete the fixation; A circuit is led out from the power supply interface of the wall panel installation robot and connected to the wall panel sensor 241, the upper drive motor 41, the lower drive motor 42 and the excitation device 3, so that the wall panel sensor 241, the upper drive motor 41, the lower drive motor 42 and the excitation device 3 are connected to the control system of the wall panel installation robot, and the wall panel sensor 241, the upper drive motor 41 and the lower drive motor 42 are automatically turned on to realize the linkage control of "robot-fixed device".

[0029] 3. Commissioning and trial operation (verifying the effectiveness of the fixed device's functions) The robot control system is started and debugged by installing the wall panel. The fixing device performs the following actions: the auxiliary slot plate extends to the maximum limit at a constant speed of 10m / s, holds for 5 seconds and then retracts to the default state; the excitation device 3 completes one excitation test run (simulating nail gun triggering); the main slot plate 1 completes one rotation within a range of ±30°; if all the above actions are normal, the debugging will end automatically. If there is an abnormality, the robot control system will issue a "debugging abnormality" warning. Based on the actual dimensions of the "wall panel connector 151", the "extension distance" of the sub-slot plate (i.e., the dimensions of the wall panel connector 151) is set in the robot control system; the nail gun is fixed between the excitation device 3 and the sub-slot cover plate 24 to ensure that the excitation device 3 can normally drive the nail gun to excite.

[0030] 4. Actual operation procedure of the fixing device After the wall panel installation robot clamps the prefabricated wall panel and moves it to the designated position, the wall panel connector 151 is installed on the upper and lower auxiliary groove cover plates 24 and the main groove plate 1 is rotated by no less than 20° through the robot control system. The robot control system sends a "start command" to the fixed device. After receiving the command, the upper drive motor 41 and the lower drive motor 42 drive the threaded rod 43 to rotate in the forward direction, causing the ball slider 25 on the threaded rod 43 to move up or down along the threaded rod 43, which further drives the upper sub-groove plate 21 to move up and the lower sub-groove plate 22 to move down. During the movement of the upper sub-slot plate 21 and the lower sub-slot plate 22, when the wall panel sensor 241 on the sub-slot cover plate 24 detects the upper or lower end of the precast wall, it sends a signal to the robot control system. After receiving the signal, the robot control system controls the upper drive motor 41 and the lower drive motor 42 to continue working, so that the threaded rod 43 continues to rotate in the forward direction and the ball slider 25 continues to move up or down until the upper sub-slot plate 21 continues to move upward and the lower sub-slot plate 22 continues to move downward by a preset "extension distance", at which point the upper drive motor 41 and the lower drive motor 42 stop working. After the main channel plate 1 is rotated -25° (or parallel to the side of the precast wall panel) by the robot control system, the upper drive motor 41 and the lower drive motor 42 are restarted, causing the threaded rod 43 to rotate and the ball slider 25 to move down or up until the upper sub-channel plate 21 moves down and the lower sub-channel plate 22 moves up by a preset "extension distance", so that the wall panel connector 151 on the sub-channel cover plate 24 is pressed into the end of the precast wall panel. The upper drive motor 41 and the lower drive motor 42 stop running, and the wall panel connector 151 is fixed. The wall panel installation robot moves and moves the prefabricated wall panel to the installation position. The prefabricated wall panel quick fixing device moves synchronously. The robot control system sends a command to the excitation device 3, causing the excitation column of the excitation device 3 to push the nail gun to fire nails. After the nails pass through the excitation hole 242, they are driven into the wall panel connector 151 and the building structure, completing the fixing of the wall panel connector 151 to the building structure. After the excitation is completed, the excitation column automatically falls back to avoid multiple excitations by the nail gun. After the excitation column falls back, the upper drive motor 41 and the lower drive motor 42 are restarted through the robot control system, causing the threaded rod 43 to rotate forward and drive the upper sub-slot plate 21 to move upward and the lower sub-slot plate 22 to move downward, until the wall panel connector 151 is disengaged from the sub-slot cover plate 24. The main slot plate 1 is then rotated 25° through the robot control system. At the same time, the upper drive motor 41 and the lower drive motor 42 drive the threaded rod 43 to rotate in reverse and drive the upper sub-slot plate 21 to move downward and the lower sub-slot plate 22 to move upward, until the upper sub-slot plate 21 and the lower sub-slot plate 22 are completely retracted into the main slot plate 1. The upper drive motor 41 and the lower drive motor 42 then enter the standby state, thus completing one prefabricated wall panel installation.
