Description

Technical Field

[0001] This utility model relates to the field of building curtain wall technology, specifically to a roof curtain wall opening and closing structure. Background Technology

[0002] In large public buildings (such as stadiums and airport terminals), roof curtain walls need to balance lighting, ventilation, and airtightness. Currently, existing roof curtain wall opening and closing structures typically employ either a translational curtain wall structure or a single-axis rotating curtain wall structure.

[0003] In a sliding curtain wall structure, the entire curtain wall slides along a horizontal track. When opening, space must be reserved for top sliding, necessitating the design of concealed cavities on the building facade. Furthermore, when the horizontal track accumulates dust or deforms, gaps easily form between the curtain wall and the frame after closing, leading to increased water seepage during rain and affecting the building's airtightness. While a rotating curtain wall structure avoids the problems of a horizontal track, the weight of the curtain wall is entirely borne by the hinge points when opening, and the corners of the curtain wall are prone to scraping against the roof frame during rotation. This necessitates an additional lifting gap (typically ≥30mm), sacrificing airtightness. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a roof curtain wall opening and closing structure, which overcomes the shortcomings of the prior art, can effectively avoid interference and jamming phenomena caused by synchronous movement, and improves the stability and reliability of the opening and closing structure.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A roof curtain wall opening and closing structure includes a curtain wall and a support frame. The curtain wall is embedded in a roof frame. A column is vertically arranged below the roof frame. A sliding guide rail is provided on the side of the column. A guide device is installed on the side of the support frame. The support frame is movably connected to the sliding guide rail through the guide device. The upper end of the support frame is connected to one end of the lower surface of the curtain wall through a first hinge seat. A lifting mechanism is provided on the side of the column. The lifting mechanism is used to control the lifting and lowering of the support frame. The side of the support frame is connected to one end of an electric push rod through a second hinge seat. The other end of the electric push rod is connected to the middle of the lower surface of the curtain wall through a third hinge seat.

[0006] Preferably, the lifting mechanism includes a worm gear jack, a servo motor, and a lifting screw. A support base is fixedly installed on the side of the column. The worm gear jack and the servo motor are both fixedly installed on the support base. The output shaft of the servo motor is connected to the input end of the reducer. The output shaft of the reducer is coaxially connected to the worm of the worm gear jack via a coupling. The lifting screw meshes with the worm wheel of the worm gear jack via a thread. The top end of the lifting screw is fixedly connected to the support frame.

[0007] Preferably, the guiding device includes a guide block, with guide wheels movably connected to both sides of the guide block. The guide wheels cooperate with the rolling grooves in the inner cavity of the sliding guide rail. A limit bearing is connected to the outer side of the guide block via a rotating shaft, and the limit bearing contacts the side wall of the sliding guide rail.

[0008] This utility model provides a roof curtain wall opening and closing structure with the following advantages: By adopting step-by-step control, the lifting mechanism first releases the clamping force between the curtain wall and the frame, eliminating rotational friction; then, the electric push rod realizes the rotational opening and closing of the curtain wall, thereby effectively avoiding interference and jamming phenomena caused by synchronous movement, and improving the stability and reliability of the opening and closing structure. Furthermore, the gravitational torque of the curtain wall can be decomposed during rotation; the axial component is borne by the electric push rod, and the radial component is balanced by the support frame, ensuring a smooth and effortless opening and closing process. The electric push rod, curtain wall, and support frame form a crank-slider-like mechanism through a first hinge seat, a second hinge seat, and a third hinge seat, making the curtain wall opening and closing process more stable and efficient, effectively avoiding inertial impact.

[0011] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0012] Example 1, as Figure 1-5 As shown, a roof curtain wall opening and closing structure includes a curtain wall 1 and a support frame 2. The curtain wall 1 is embedded in a roof frame 3. A column 4 is vertically arranged below the roof frame 3. A sliding guide rail 5 is provided on the side of the column 4. Multiple guide devices 6 are installed on the side of the support frame 2. The support frame 2 is movably connected to the sliding guide rail 5 through the guide devices 6. The upper end of the support frame 2 is connected to one end of the lower surface of the curtain wall 1 through a first hinge seat 7. A lifting mechanism 8 is provided on the side of the column 4. The lifting mechanism 8 is used to control the lifting and lowering of the support frame 2. The side of the support frame 2 is connected to one end of an electric push rod 10 through a second hinge seat 9. The other end of the electric push rod 10 is connected to the middle of the lower surface of the curtain wall 1 through a third hinge seat 11. The electric push rod 10, the curtain wall 1, and the support frame 2 form a crank-connecting rod mechanism through the first hinge seat 7, the second hinge seat 9, and the third hinge seat 11.

[0013] Working principle: When the roof curtain wall needs to be opened, the lifting mechanism 8 is first activated, which drives the support frame 2 to move vertically upward along the sliding guide rail 5. This raises the curtain wall 1 a certain distance, allowing it to detach from the roof frame 3 and effectively avoid friction between the curtain wall 1 and the roof frame 3. During this process, the guide block 15 and the sliding guide rail 5 work together to ensure the smooth movement of the support frame 2. Then, the telescopic shaft of the electric push rod 10 is extended, allowing the curtain wall 1 to rotate upward around the first hinge seat 7 via the third hinge seat 11 until the curtain wall 1 is fully opened. After reaching the predetermined position, the electric push rod 10 locks to ensure the stability of the curtain wall 1.

[0014] Similarly, when the roof curtain wall needs to be closed, the electric push rod 10 is first controlled to retract, pulling the curtain wall 1 downward around the first hinge seat 7 so that the curtain wall 1 returns to a horizontal state. In this embodiment, an angle sensor can be installed on the curtain wall 1 to provide feedback on the angle of the curtain wall, thereby ensuring the accuracy of the rotation of the curtain wall 1. Then, the lifting mechanism 8 is controlled to drive the support frame 2 to move vertically downward along the sliding guide rail 5 until the curtain wall 1 is re-embedded in the groove of the roof frame 3, ensuring that the curtain wall 1 and the roof frame 3 fit tightly together to prevent wind and rain from entering.

[0015] In this invention, by employing step-by-step control, the lifting mechanism 8 first releases the clamping force between the curtain wall and the frame, eliminating rotational friction; then, the electric push rod 10 realizes the rotational opening and closing of the curtain wall 1, thereby effectively avoiding interference and jamming phenomena caused by synchronous movement, and improving the stability and reliability of the opening and closing structure. Furthermore, the gravitational torque of the curtain wall 1 can be decomposed during rotation; the axial component is borne by the electric push rod 10, and the radial component is balanced by the support frame 2, ensuring a smooth and effortless opening and closing process. The electric push rod 10, the curtain wall 1, and the support frame 2 form a crank-slider-like mechanism through the first hinge seat 7, the second hinge seat 9, and the third hinge seat 11, making the curtain wall opening and closing process more stable and efficient, effectively avoiding inertial impact.

[0016] In Example 2, as a further preferred embodiment of Example 1, the lifting mechanism 8 includes a worm gear jack 81, a servo motor 82, and a lifting screw 83. A support base 12 is fixedly installed on the side of the column 4. Both the worm gear jack 81 and the servo motor 82 are fixedly installed on the support base 12. The output shaft of the servo motor 82 is connected to the input end of the reducer 84. The output shaft of the reducer 84 is coaxially connected to the worm of the worm gear jack 81 through a coupling. The lifting screw 83 meshes with the worm wheel of the worm gear jack 81 through a thread. The top end of the lifting screw 83 is fixedly connected to the support frame 2.

[0017] Therefore, when it is necessary to control the support frame 2 to move up or down, the forward and reverse rotation of the servo motor 82 is controlled, which, through the transmission action of the reducer 84, drives the worm of the worm gear lift 81 to rotate. This, in turn, through the meshing transmission between the worm and the worm wheel, drives the lifting screw 83 to move vertically up and down, thereby synchronously raising and lowering the support frame 2 at the upper end of the lifting screw 83. This achieves precise opening and closing of the curtain wall 1, ensuring the overall structural coordination and safety.

[0018] In embodiment three, as a further preferred embodiment one, the guiding device 6 includes a guide block 15. Two guide wheels 13 are movably connected to both sides of the guide block 15. The guide wheels 13 cooperate with the rolling grooves in the inner cavity of the sliding guide rail 5. The guide wheels 13 are double-row stainless steel rollers, and the sliding guide rail 5 has a T-groove. The tight cooperation between the double-row stainless steel rollers and the sliding guide rail 5 effectively reduces the frictional resistance of the support frame 2 during sliding, improving the smoothness of the support frame 2's movement. Furthermore, a limit bearing 14 is connected to the outer side of the guide block 15 via a rotating shaft. The limit bearing 14 contacts the side wall of the sliding guide rail 5. The contact between the limit bearing 14 and the side wall of the sliding guide rail 5 effectively limits the lateral displacement of the support frame 2, ensuring its stable operation within the sliding guide rail 5, further improving the overall structural stability and service life.

[0019] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
