Abstract
Description
Technical Field
[0001] This utility model belongs to the field of building engineering technology, specifically a precise positioning device for a frame-type curtain wall unit adapter. Background Technology
[0002] When installing some building curtain walls, unitized curtain wall adapters and positioning devices are required to connect the curtain wall unit panels to the main structure. However, some existing unitized curtain wall adapters typically use traditional mechanical connection methods during actual construction, resulting in low positioning accuracy and difficulty in achieving rapid and precise adjustments under complex conditions. This leads to low construction efficiency and unstable installation quality. A search revealed a unitized curtain wall adapter adjustment device (publication number CN103015591B) that connects unit panels to the main structure using C-shaped channel steel embedded parts, T-bolt assemblies, and toothed hanging plates, and adjusts the position using limit and fine-tuning bolts. However, this design relies on manually adjusting the limit nuts and fine-tuning bolts, involving numerous steps, and the adjustment accuracy is limited by the operator's skill level, making it difficult to meet high-precision installation requirements. Furthermore, this design has limited adjustment capabilities in three-dimensional space, failing to flexibly adapt to complex on-site environments. A search revealed a three-dimensional adjustable mounting device for unitized curtain walls (publication number CN102535704B). This device, through a combination of adapters and mounting hardware, enables three-dimensional adjustment of unit panels in the front, back, top, bottom, left, and right directions. While this design improves work efficiency and reduces installation costs, the adjustment process still relies on the coordination of multiple bolt components, making the assembly process relatively complex. Furthermore, the adjustment range is structurally limited, making it difficult to meet the needs of large-scale dynamic adjustments. Additionally, this design may pose a risk of loosening during long-term use, affecting overall stability. These issues indicate that traditional unitized curtain wall adapters and positioning devices currently on the market still have limitations in meeting the requirements for precise positioning and rapid adjustment under complex working conditions.

[0018] This utility model provides a precise positioning device for a frame-type curtain wall unit adapter, the specific implementation of which is described in conjunction with the attached diagram. Figure 1 To be continued Figure 4 Please provide a detailed explanation. For example... Figure 1 As shown, the overall structure includes a base 1, an adjustment disc 2, a drive assembly 3, a support frame 4, a limiting mechanism 5, and an angle sensor 6. The specific connection relationships, positional relationships, and mutual cooperation relationships of each component are described below.
[0019] The base 1 is the fundamental component of the entire device, used for fixed installation on the main building structure. Its bottom is equipped with a mounting flange 7, which has multiple mounting holes, each containing an anti-loosening washer 17. The anti-loosening washers 17 are fixed in the mounting holes by compression to improve the installation stability between the base 1 and the main building structure. The top of the base 1 has a groove with a wear-resistant layer on its inner wall, which is bonded to the groove to reduce frictional loss during the rotation of the adjusting disc 2. The adjusting disc 2 is rotatably mounted in the groove of the base 1 via bearings. The outer circumference of the adjusting disc 2 has toothed grooves for meshing with the transmission gears in the drive assembly 3.
[0020] The drive assembly 3 is fixedly mounted on the base 1, and includes a motor bracket, a stepper motor 8, a drive gear 9, and a limiting plate 10. The motor bracket is fixedly mounted on one side of the base 1, and the stepper motor 8 is fixedly mounted on the motor bracket. The drive gear 9 is fixedly sleeved on the output shaft of the stepper motor 8, and the drive gear 9 meshes with the tooth groove on the adjusting plate 2. The limiting plate 10 is fixedly mounted on the motor bracket to constrain the axial position of the drive gear 9, thereby ensuring the meshing accuracy between the drive gear 9 and the adjusting plate 2. In addition, a control module is also provided on the motor bracket. The control module includes a circuit board, a microprocessor, a wireless communication module, and a power interface. The circuit board is fixedly mounted on the motor bracket, and both the microprocessor and the wireless communication module are fixedly mounted on the circuit board. The wireless communication module is used to receive external control commands, and the power interface is used to connect to an external power source, thereby controlling the working state of the stepper motor 8.
[0021] The support frame 4 is connected to the adjusting plate 2 via a threaded connection. The support frame 4 includes a bearing plate, reinforcing ribs, and positioning pins. The bearing plate is fixedly installed at the top of the guide rod 11. The bearing plate is provided with mounting holes for fixing the curtain wall unit panels. The position and size of the mounting holes are determined according to the design requirements of the actual curtain wall unit panels. The reinforcing ribs are fixedly installed at the bottom of the bearing plate and welded to the guide rod 11 to enhance the overall structural strength of the support frame 4. The positioning pins are fixedly installed on the side of the bearing plate. The positioning pins are used to engage with the positioning holes on the curtain wall unit panels to achieve initial positioning. The guide rod 11 is fixedly installed at the bottom of the support frame 4. The guide rod 11 passes through the adjusting plate 2 and is slidably connected to the adjusting plate 2, thereby ensuring that the support frame 4 moves in a specific direction.
[0022] A limiting mechanism 5 is disposed between the support frame 4 and the adjusting plate 2 to restrict the movement of the support frame 4 in a specific direction. The limiting mechanism 5 includes a guide rod 11, an elastic element 12, and a limiting block 13. The limiting block 13 is fixedly installed at the bottom end of the guide rod 11. The limiting block 13 is used to limit the range of movement of the guide rod 11, thereby preventing the support frame 4 from shifting during adjustment. The elastic element 12 is fixedly sleeved on the guide rod 11. One end of the elastic element 12 abuts against the bottom of the support frame 4, and the other end abuts against the top of the adjusting plate 2. The function of the elastic element 12 is to provide a certain buffering force for the support frame 4 and ensure that the support frame 4 remains stable during adjustment.
[0023] An angle sensor 6 is mounted on the base 1 and is used to detect the rotation angle of the adjustment disk 2. The angle sensor 6 includes a sensor bracket, a photoelectric encoder 14, a signal gear disk 15, and a protective cover 16. The sensor bracket is fixedly mounted on the base 1, the photoelectric encoder 14 is fixedly mounted on the sensor bracket, and the signal gear disk 15 is fixedly mounted on the outer periphery of the adjustment disk 2. The signal gear disk 15 corresponds to the detection head of the photoelectric encoder 14, and the photoelectric encoder 14 monitors the rotation angle of the adjustment disk 2 in real time by detecting changes in the number of teeth on the signal gear disk 15. The protective cover 16 is fixedly mounted on the sensor bracket to protect the photoelectric encoder 14 and prevent external environmental factors from affecting it.
[0024] In practical applications, the working principle of this utility model is as follows: First, the base 1 is fixedly installed on the main building structure via the mounting flange 7 to ensure accurate installation. Then, the curtain wall unit panel is placed on the support plate of the support frame 4, and initial positioning is achieved by the positioning pin engaging with the positioning holes on the curtain wall unit panel. Next, external control commands are received via the wireless communication module, and the microprocessor in the control module controls the stepper motor 8 to start according to the received commands. The output shaft of the stepper motor 8 drives the drive gear 9 to rotate, and the drive gear 9 meshes with the tooth groove on the adjustment plate 2, thereby driving the adjustment plate 2 to rotate. The adjustment plate 2 is connected to the support frame 4 via a threaded connection. When the adjustment plate 2 rotates, the support frame 4 moves along the axial direction of the guide rod 11, thereby achieving rapid and high-precision adjustment of the curtain wall unit panel. During this process, the elastic element 12 and the limit block 13 in the limiting mechanism 5 work together to ensure that the support frame 4 does not shift during adjustment, while the sliding connection between the guide rod 11 and the adjustment plate 2 further ensures that the movement direction of the support frame 4 is precise and controllable. The photoelectric encoder 14 in the angle sensor 6 monitors the rotation angle of the adjustment disk 2 in real time and feeds back the monitoring data to the control module. The control module dynamically adjusts the operating status of the stepper motor 8 according to the feedback data, thereby achieving precise control of the position of the curtain wall unit panel.
[0025] In the above embodiments, all components are described with specific connection methods and positional relationships, ensuring that those skilled in the art can implement the technical solution based on the contents of the specification. The cooperation relationship between the components is clear and close, effectively solving the problem in the prior art that unitized curtain wall transition components are difficult to adjust quickly and with high precision under complex working conditions.
[0026] To enable those skilled in the art to fully understand and implement this utility model, the specific implementation principle of this utility model is further supplemented below with a specific application scenario.
[0027] During the installation of the building curtain wall, the base 1 is first fixed to the main building structure using the mounting flange 7. Multiple mounting holes on the mounting flange 7 are fitted with anti-loosening washers 17, which are tightened to improve the connection stability between the base 1 and the main building structure. Subsequently, the curtain wall unit panels are placed on the support plate of the support frame 4, and initial positioning is completed by engaging the positioning pins with the positioning holes on the curtain wall unit panels. This initial positioning ensures that the curtain wall unit panels will not shift significantly during subsequent adjustments, laying the foundation for high-precision adjustments.
[0028] Next, the microprocessor receives external control commands via the wireless communication module and starts the stepper motor 8 according to the received commands. The output shaft of the stepper motor 8 drives the drive gear 9 to rotate, and the drive gear 9 meshes with the tooth grooves on the outer periphery of the adjustment disk 2, thereby driving the adjustment disk 2 to rotate. The adjustment disk 2 is connected to the support frame 4 through a threaded connection. When the adjustment disk 2 rotates, the support frame 4 moves along the axial direction of the guide rod 11. During this process, the guide rod 11 passes through the adjustment disk 2 and slides with it, ensuring that the movement direction of the support frame 4 is precisely controllable. At the same time, the elastic element 12 and the limit block 13 in the limiting mechanism 5 work together to limit the movement range of the guide rod 11 and prevent the support frame 4 from shifting during the adjustment process. The elastic element 12 also provides a certain buffer force for the support frame 4 to ensure that it remains stable during the adjustment process.
[0029] Meanwhile, the photoelectric encoder 14 in the angle sensor 6 monitors the rotation angle of the adjustment disk 2 in real time. The photoelectric encoder 14 feeds back the monitoring data to the control module by detecting changes in the number of teeth on the signal toothed disk 15. The control module dynamically adjusts the operating state of the stepper motor 8 based on the feedback data, thereby achieving precise control of the position of the curtain wall unit panels. The protective cover 16 protects the photoelectric encoder 14 from external environmental factors, ensuring the long-term reliability of the angle sensor 6.
[0030] In actual construction, the above process enables rapid three-dimensional adjustment of the curtain wall unit panels. For example, when it is necessary to adjust the front and rear positions of the curtain wall unit panels, the stepper motor 8 drives the adjustment disk 2 to rotate. The rotation of the adjustment disk 2 is converted into the axial movement of the support frame 4 along the guide rod 11, thereby achieving precise position adjustment. Due to the precise control characteristics of the stepper motor 8 and the real-time monitoring function of the photoelectric encoder 14, the adjustment accuracy is significantly improved. In addition, the wear-resistant layer set on the inner wall of the groove at the top of the base 1 reduces the frictional loss when the adjustment disk 2 rotates, extending the service life of the device.
[0031] In complex working conditions, such as when large-scale dynamic adjustments are required, the design advantages of this invention are particularly prominent. By receiving external commands through the wireless communication module, the microprocessor can flexibly adjust the operating parameters of the stepper motor 8 to adapt to different adjustment needs. Simultaneously, the elastic element 12 and the limiting block 13 in the limiting mechanism 5 effectively limit the movement range of the support frame 4, ensuring the safety and stability of the adjustment process. This design not only improves construction efficiency but also reduces the risk of errors caused by improper manual operation.
[0032] In summary, this invention achieves rapid and high-precision adjustment of curtain wall unit panels through the close cooperation of its components, solving the problem of insufficient precision positioning and rapid adjustment under complex working conditions in existing technologies. All components are described with specific connection methods and positional relationships to ensure that those skilled in the art can implement this technical solution based on the description.
[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
