Description

Technical Field

[0001] This utility model relates to the technical field of curtain wall lifting equipment, specifically a GRC curtain wall fine-adjustment lifting device. Background Technology

[0002] GRC curtain wall is a building exterior wall decoration structure made of glass fiber reinforced concrete as the main material. It has many characteristics such as beautiful appearance, high strength and good durability. During its installation, due to deviations in the building structure or the requirements of installation accuracy, it is necessary to make fine adjustments to the curtain wall panels to achieve the ideal installation position. This device can make small adjustments to the GRC curtain wall panels in the vertical direction (lifting).

[0003] The fine-tuning lifting device can precisely raise the curtain wall panels to the same height as the adjacent panels or adjust them to the required elevation position, ensuring the overall flatness and aesthetics of the curtain wall. However, most existing GRC curtain walls are adjusted in height by hoisting during installation. During hoisting, construction workers mainly rely on experience and simple measuring tools to roughly determine the installation height of the curtain wall. Since the hoisting equipment itself cannot provide high-precision vertical positioning and fine height adjustment functions, it is difficult to meet the more precise height adjustment requirements during the installation of GRC curtain walls. Utility Model Content

[0004] The purpose of this utility model is to address the problem that, during the installation of existing GRC curtain walls, the height is mostly adjusted by hoisting. During the hoisting process, construction workers mainly rely on experience and simple measuring tools to roughly determine the installation height of the curtain wall. Since the hoisting equipment itself cannot provide high-precision vertical positioning and fine height adjustment functions, it is difficult to meet the more precise height adjustment requirements during the installation of GRC curtain walls. Therefore, this utility model provides a GRC curtain wall fine-adjustment lifting device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a GRC curtain wall fine-adjustment lifting device, comprising: a support frame, a toothed frame vertically slidably connected to the inner side of the support frame, a rotating shaft rod rotatably connected to the middle of the inner side of the support frame, a gear one fixedly connected to one end of the outer wall of the rotating shaft rod, a gear two fixedly connected to the other end of the outer wall of the rotating shaft rod, a motor bracket fixedly connected to one end of the outer side of the support frame, a motor fixedly connected to the inner side of the motor bracket, and a drive mechanism provided on the front of the toothed frame.

[0006] As a further embodiment of this utility model: the driving mechanism includes a fixed frame, a supporting outer sleeve, and a cylinder. The fixed frame is fixedly connected to the front of the toothed frame, and the supporting outer sleeve is fixedly connected to one end inside the fixed frame; the cylinder and a clamping assembly are also included. The cylinder is fixedly connected to the middle of the fixed frame, and the clamping assembly is located at the movable end of the cylinder.

[0007] As a further embodiment of this utility model: the clamping assembly includes a pneumatic suction cup, a telescopic inner rod, and a cross connecting frame. The telescopic inner rod is fixedly connected to one end of the back of the pneumatic suction cup, and the cross connecting frame is fixedly connected to one end of the telescopic inner rod. The other end of the telescopic inner rod is slidably connected to the outer support sleeve, and the movable end of the cylinder is fixedly connected to the cross connecting frame.

[0008] As a further embodiment of this utility model: both gear one and gear two are meshed with the toothed frame, and the other end of the rotating shaft passes through the support frame and is fixedly connected to the motor output end.

[0009] As a further improvement of this utility model, the number of the supporting outer sleeves is provided as four sets, which are symmetrically arranged at four ends inside the fixed frame.

[0010] As a further improvement of this utility model: the telescopic inner rods are provided in four sets, which are symmetrically arranged at the four ends of the back of the pneumatic suction cup, and all four sets of telescopic inner rods are fixedly connected to the cross connecting frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, a cylinder pushes a cross-shaped connecting frame, which in turn drives a pneumatic suction cup forward via a telescopic inner rod to adhere to and adhere to the GRC curtain wall, ensuring precise positioning and preparing for lifting. A motor drives a rotating shaft to rotate, which in turn causes a toothed frame to move linearly via gears one and two, resulting in high transmission precision and allowing for accurate adjustment of the curtain wall height. The toothed frame slides vertically, causing the drive mechanism and pneumatic suction cup to move upward synchronously, ensuring the curtain wall is lifted vertically and avoiding tilting or offset, thus ensuring flatness and verticality. Four sets of telescopic inner rods cooperate with the supporting outer sleeve to ensure stable adsorption and lifting. The device can flexibly adjust the suction cup position to adapt to different curtain walls and precisely control the lifting height, making it suitable for various fine-tuning scenarios.

The embodiments of this utility model will be described below based on its overall structure.

[0021] Reference Figures 1 to 5 In this embodiment of the utility model, a GRC curtain wall fine-adjustment lifting device includes: a support frame 1, which serves as the basic support structure for the entire GRC curtain wall fine-adjustment lifting device, providing a foundation for the installation and support of other components, and ensuring the stability of the device during operation; a toothed frame 2 is vertically slidably connected to the inner side of the support frame 1; and a rotating shaft 3 is rotatably connected to the middle of the inner side of the support frame 1, serving as a transmission component.

[0022] Gear 4 is fixedly connected to one end of the outer wall of the rotating shaft 3, and gear 5 is fixedly connected to the other end of the outer wall of the rotating shaft 3. A motor bracket 6 is fixedly connected to one end of the outer side of the support frame 1, and a motor 7 is fixedly connected to the inner side of the motor bracket 6. The toothed frame 2 is meshed with gear 4 and gear 5. When the motor 7 drives the rotating shaft 3 to rotate, the toothed frame 2 can slide vertically inside the support frame 1 through the transmission action of the gears. This vertical sliding realizes the vertical movement of the adsorbed GRC curtain wall panel, thereby completing the fine-tuning lifting operation, ensuring that the curtain wall panel rises along the vertical direction, and ensuring its flatness and verticality. A drive mechanism 8 is provided on the front of the toothed frame 2. Gear 4 and gear 5 are both meshed with the toothed frame 2. The other end of the rotating shaft 3 passes through the support frame 1 and is fixedly connected to the output end of the motor 7.

[0023] Reference Figure 1 , Figure 3 and Figure 4 The drive mechanism 8 includes a fixed frame 801, a supporting outer sleeve 802, and a cylinder 803. The fixed frame 801 is fixedly connected to the front of the toothed frame 2, and the supporting outer sleeve 802 is fixedly connected to one end inside the fixed frame 801.

[0024] The cylinder 803 is fixedly connected to the middle of the fixed frame 801, and the clamping assembly 9 is located at the movable end of the cylinder 803. There are four sets of supporting outer sleeves 802, which are symmetrically arranged at four ends inside the fixed frame 801.

[0025] Reference Figure 1 , Figure 3 and Figure 5 The clamping assembly 9 includes a pneumatic suction cup 901, a telescopic inner rod 902, and a cross connecting frame 903. The telescopic inner rod 902 is fixedly connected to one end of the back of the pneumatic suction cup 901, and the cross connecting frame 903 is fixedly connected to one end of the telescopic inner rod 902.

[0026] The other end of the telescopic inner rod 902 is slidably connected to the supporting outer sleeve 802. The movable end of the cylinder 803 is fixedly connected to the cross connecting frame 903. There are four sets of telescopic inner rods 902, symmetrically arranged at the four ends of the back of the pneumatic suction cup 901. All four sets of telescopic inner rods 902 are fixedly connected to the cross connecting frame 903. The cylinder 803 pushes the cross connecting frame 903 forward. Due to the connection relationship between the telescopic inner rod 902 and the cross connecting frame 903 and the pneumatic suction cup 901, as well as the connection relationship between the telescopic inner rod 902 and the supporting outer sleeve 802, the movement of the cross connecting frame 903 will drive the telescopic inner rod 902 and the pneumatic suction cup 901 to move forward synchronously until the pneumatic suction cup 901 adheres to the surface of the GRC curtain wall panel and is adsorbed. Then, the motor 7 drives the rotating shaft 3. As gears 4 and 5 are meshed with the toothed frame 2, when the rotating shaft 3 rotates, gears 4 and 5 will rotate accordingly, causing the toothed frame 2 to move in a straight line. This transmission method has high precision. The meshing of gears 4 and 5 with the toothed frame 2 can precisely control the moving distance of the toothed frame 2, thereby realizing minute height adjustments of the GRC curtain wall panels and meeting the strict precision requirements during the installation or maintenance of GRC curtain walls. As the toothed frame 2 slides vertically inside the support frame 1, the drive mechanism 8 connected to it, as well as the pneumatic suction cup 901 that adsorbs the GRC curtain wall panels, will also move vertically in sync, thereby driving the GRC curtain wall panels to rise in the vertical direction and realizing the fine-tuning and lifting operation of the GRC curtain wall panels.

[0027] The working principle of this utility model is as follows:

[0028] Step 1: The cylinder 803 pushes the cross connecting frame 903 forward. Due to the connection relationship between the telescopic inner rod 902 and the cross connecting frame 903 and the pneumatic suction cup 901, as well as the connection relationship between the telescopic inner rod 902 and the supporting outer sleeve 802, the movement of the cross connecting frame 903 will drive the telescopic inner rod 902 and the pneumatic suction cup 901 to move forward synchronously until the pneumatic suction cup 901 is attached to the surface of the GRC curtain wall panel and adsorbed. This step-by-step approach can accurately locate the part that needs to be adsorbed, reduce positioning errors, provide an accurate starting point for subsequent lifting operations, and prepare for subsequent lifting operations.

[0029] Step two: After the GRC curtain wall panel is stably adsorbed by the pneumatic suction cup 901, the motor 7 drives the rotating shaft 3 to rotate. Since gears 4 and 5 are both meshed with the toothed frame 2, when the rotating shaft 3 rotates, gears 4 and 5 will rotate accordingly, causing the toothed frame 2 to move linearly. This transmission method has high precision. The meshing of gears 4 and 5 with the toothed frame 2 can precisely control the moving distance of the toothed frame 2, thereby achieving minute height adjustments of the GRC curtain wall panel and meeting the strict precision requirements during GRC curtain wall installation or maintenance. As the toothed frame 2 slides vertically inside the support frame 1, the drive mechanism 8 connected to it, as well as the pneumatic suction cup 901 adsorbing the GRC curtain wall panel and other components, will also move vertically synchronously, thereby driving the GRC curtain wall panel along... The device rises vertically to perform fine-tuning and lifting operations on the GRC curtain wall panels. This method and structural design ensure the accuracy of the lifting direction, allowing the GRC curtain wall to move only vertically. Throughout the lifting process, due to the stability of the structure, there will be no tilting or deviation, ensuring the flatness and verticality of the GRC curtain wall. During the lifting process, four sets of telescopic inner rods 902 and the supporting outer sleeve 802 work together to ensure that the pneumatic suction cup 901 maintains a stable adsorption state and vertical movement, ensuring the accuracy and stability of the lifting. The entire method allows for flexible adjustment of the position of the pneumatic suction cup 901 to adapt to the adsorption needs of GRC curtain wall panels of different sizes and shapes, and the lifting height can be precisely controlled by the motor 7. This flexibility makes the device suitable for a variety of different GRC curtain wall fine-tuning scenarios.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
