Description

Technical Field

[0001] This application belongs to the technical field of curtain wall construction, and specifically relates to a connecting device for curtain wall positioning keels. Background Art

[0002] In order to achieve the purpose of beautiful building appearance, secondary keels of curtain walls are mostly symmetrically welded on both sides of the main keel. High requirements are imposed on the straightness and unified bending angle during welding. During building decoration construction, square tubes of primary and secondary keels are generally directly welded on the ground during assembly welding. It is easy to weld for regular-shaped decorative keels, but for specific decorative keels with different butt angles, there are major problems with the direct welding operation method. Since the square tubes are prone to move during the welding process, the assembly joint runs off, resulting in misalignment after welding and becoming scrap that cannot be used, increasing the investment in construction costs.

[0003] For example, a curtain wall keel welding positioning device in the publication number CN117984034A, which relates to the technical field of curtain wall construction, includes: a mounting base detachably fixed on the main keel, a rotating shaft provided on the mounting base, two connecting plates rotatably connected to the rotating shaft, and a clamping component for clamping the secondary keel provided on each connecting plate; an adjusting component connected to the two connecting plates for adjusting the included angle between them. The present invention solves the problems of inconvenient adjustment of welding angles and inability to weld and position primary and secondary keels at high altitudes in the prior art.

[0004] However, this device can only be installed at one height. When the height needs to be adjusted, re-drilling and fixing are required, reducing the installation efficiency. Summary of the Utility Model

[0005] The purpose of this application is to provide a connecting device for curtain wall positioning keels to solve the problem that the above-mentioned device can only be installed at one height, and when the height needs to be adjusted, re-drilling and fixing are required, reducing the installation efficiency.

[0006] The technical solution adopted in this application is as follows: A curtain wall positioning keel connection device includes a main keel. A fixed clamping device is provided at the top of the main keel. A top mounting block is provided on one side of the fixed clamping device. A traction motor is installed inside one side of the top mounting block. A rotating shaft is provided at one end of the traction motor. Traction ropes are wound around the outer surfaces of both ends of the rotating shaft. The lower end of the traction rope is provided with a mounting base. Electric push rod 1 is installed on both sides of the upper surface of the mounting base. A telescopic rod 1 is inserted into the upper end of the electric push rod 1.

[0007] By adopting the above technical solution, through the above design, the traction rope pulls the mounting base, which can adjust the height of the mounting base, facilitating the installation of secondary keels at different heights without repeatedly disassembling and assembling the top mounting block, improving the installation efficiency and convenience.

[0010] In a preferred embodiment, a limiting chute 1 is opened inside the chute 1. A limiting slider 1 is provided at one end of the moving block 1. The limiting slider 1 is slidably connected inside the limiting chute 1.

[0011] By adopting the above technical solution, by the limiting slider 1 sliding inside the limiting chute 1, the movement of the moving block 1 is made more stable, improving the stability of the movement and thus improving the stability of the device.

[0012] In a preferred embodiment, a second chute is provided on one side surface of the mounting base. A two-way lead screw two is threadedly connected inside the second chute. Moving blocks two are threadedly connected to the outer surfaces of both ends of the two-way lead screw two. One end of each moving block two is provided with a clamping plate, and a walking wheel is provided on one side surface of the clamping plate.

[0013] By adopting the above technical solution, by rotating the two-way lead screw two, the clamping plate is driven to move, so that the walking wheel can be abutted against the surface of the main keel. The walking wheel can drive the mounting base to move, improving the stability of its movement. Moreover, the walking wheel can clamp the main keel, improving the stability of the installation of the mounting base.

[0014] In a preferred embodiment, a second limiting chute is provided inside the second chute. A sliding rod is provided inside the second limiting chute. One end of the moving block two is provided with a second limiting slider, and the second limiting slider is slidably connected to the outer surface of the sliding rod.

[0015] By adopting the above technical solution, by sliding the second limiting slider on the outer surface of the sliding rod, the movement of the moving block two is limited, making its operation smoother and improving the stability of the clamping plate.

[0016] In a preferred embodiment, an electric push rod three is installed on one side surface of the clamping plate, and a telescopic rod three is inserted inside one end of the electric push rod three.

[0017] By adopting the above technical solution, the electric push rod three drives the telescopic rod three to move, making it abutted against the surface of the main keel, improving the stability of the mounting base.

[0018] In a preferred embodiment, a level is installed on one side surface of the electric push rod two.

[0019] By adopting the above technical solution, the level can detect the horizontal state of the clamping device, ensuring that it is always in a horizontal state and improving the stability.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0021] In this application, during installation, the top mounting block is installed on the top of the main keel through the fixed clamping device. Then, the traction motor drives the rotation of the rotating shaft, so that the length of the traction rope is adjusted, and further the height of the mounting base is adjusted. The electric push rod II drives the telescopic rod II to move, so that the clamping device moves towards the secondary keel. The electric push rod I drives the telescopic rod I to adjust the height, so that the clamping device approaches the secondary keel. The clamping device clamps, and at the same time, the motor I drives the clamping device to rotate, which can adjust the installation angle of the secondary keel to adapt to the installation of secondary keels with different designs. The motor II can drive the clamping device to rotate, which can adjust the installation direction of the secondary keel, improving the practicability, installation efficiency and convenience.
