[0053] See Figure 1 、 Figure 2 、 Figure 4 and Figure 5 The utility model provides a technical solution: a retractable awning device installed on a portal frame, comprising: a connecting frame 1, a first bracket 3, a second bracket 5 and an awning cloth 4. The connecting frame 1 includes a first horizontal frame 101, a first vertical frame 102 and a second vertical frame 103. The two ends of the first horizontal frame 101 are respectively connected to the first vertical frame 102 and the second vertical frame 103. The first bracket 3 includes a first bracket rod 301 and a first bracket arm 302, and the first bracket 3 has a built-in space for placing the awning cloth 4. One end of the first bracket rod 301 is set on the first vertical frame 102, and the other end of the first bracket rod 301 is hinged to the first bracket arm 302. The second bracket 5 includes a second bracket rod 501 and a second bracket arm 502. One end of the second bracket rod 5 is set on the second vertical frame 103, and the other end of the second bracket rod 501 is hinged to the second bracket arm 502. One end of the awning cloth 4 is fixedly connected to the first bracket 3 , and the other end of the awning cloth 4 is detachably connected to the second bracket 5 , so as to fix the awning cloth 4 and the second bracket 5 .

[0054] It should be noted that the rotation of the first support arm 302 on the first support rod 301 and the rotation of the second support arm 502 on the second support rod 501 are both horizontal rotations.

[0055] See Figure 4 、 Figure 5 、 Figure 12 and Figure 13Specifically, when the awning device is in use, first, the connecting frame 1 is secured to the crossbeam of the portal frame. Then, the first support arm 302 and the second support arm 502 are unfolded, the awning fabric 4 located on the first support rod 301 is removed, and the awning fabric 4 is stretched toward the second support rod 501. Finally, the movable end of the awning fabric 4 is secured to the second support rod 501 and the second support arm 502.

[0056] When the awning device is temporarily out of use, the free end of the awning fabric 4 is removed from the second support rod 501 and the second support arm 502, and stored back into the first support rod 301, and then the first support arm 302 and the second support arm 502 are folded together. Furthermore, when the construction work is completed and the awning device is no longer needed, the connecting frame 1 is removed from the crossbeam of the portal frame.

[0057] This technical solution, through the connection frame and the provision of adjustable first support arm 302 and second support arm 502, makes the installation and removal of the canopy device extremely convenient. When the canopy device is no longer needed, it can be promptly retracted, saving space and eliminating conflicts with equipment operations at the construction site. This solves the problem that most canopy devices used at construction sites are fixed, which hinders construction operations, and that fixed canopy devices cannot be retracted when not needed, thus taking up space.

[0058] The connecting frame 1 , the first bracket 3 , and the second bracket 5 are made of metal materials, such as steel or aluminum alloy, to ensure that the connecting frame 1 , the first bracket 3 , and the second bracket 5 have sufficient strength and durability.

[0059] See Figure 1 Furthermore, a connecting plate 2 is provided on the first transverse frame 101, and the connecting plate 2 is fixed on the crossbeam of the portal frame. The connecting plate 2 is fixed on the crossbeam of the portal frame by screwing.

[0060] See Figure 1 、 Figure 4 and Figure 10 In some embodiments, the retractable awning device installed on the portal frame also includes a drum 6, one end of the drum shaft of the drum 6 is connected to the first bracket rod 301 through a bearing, and the other end of the drum shaft of the drum 6 is detachably arranged on the first bracket arm 302, and the drum 6 rotates around the bearing in the first bracket rod 301.

[0061] See Figure 4 、 Figure 8 、 Figure 10 and Figure 11Furthermore, the retractable awning device mounted on the portal frame further includes a snap-on member 21, which is disposed on the first bracket arm 302 and secured to the end of the reel 6 away from the bearing. Preferably, a plurality of magnetic tiles 19 are disposed on the movable end of the awning fabric 4. When the second bracket 5 is made of a magnetic metal material, the awning fabric 4 can be conveniently secured to the second bracket 5. When the second bracket 5 is made of a non-magnetic metal material, a magnetic tile holder is required at a corresponding position on the second bracket 5. The magnetic tile 19 cooperates with the magnetic tile holder to secure the awning fabric 4 to the second bracket 5.

[0062] See Figure 8 , wherein the bearing is a well-known component and the present application does not make any improvements thereto. The outer ring of the bearing is fixedly disposed in the first support rod 301, the inner ring of the bearing is sleeved on and fixes one end of the reel of the reel 6, and a latch 21 is disposed on the first support arm 302. The latch 21 is a latch having two opposing protruding teeth, i.e., it is used to fix the end of the reel of the reel 6 away from the bearing. When the first support arm 302 is unfolded away from the first support rod 301 until it is parallel to the first support rod 301, the end of the reel of the reel 6 away from the bearing is engaged with the latch 21 and can be rotated in the latch 21, so that the reel of the reel 6 is more stable when rotating. When the first support arm 302 is stored close to the first support rod 301, the top paddle of the latch 21 is lifted, and the end of the reel of the reel 6 away from the bearing is disengaged from the latch 21.

[0063] It should be noted that the first bracket arm 302 can be configured to have a vertical cross-section of 匚-shaped, with the latch 21 disposed on the inner sidewall of the lower end of the first bracket arm 302. Alternatively, the first bracket arm 302 can be configured to have a plate-like structure, with the latch 21 disposed on the top surface of the first bracket arm 302.

[0064] See Figure 1 and Figure 2 In some embodiments, the first vertical frame 102 is provided with a first guide rail 7, and the second vertical frame 103 is provided with a second guide rail 8. A first slider 9 is provided within the first guide rail 7, and a second slider 10 is provided within the second guide rail 8. The first slider 9 slides within the first guide rail 7 and is connected to the first support rod 301. The second slider 10 slides within the second guide rail 8 and is connected to the second support rod 501.

[0065] The first slider 9 slides within the first guide rail 7, driving the first bracket 3 to move synchronously. The second slider 10 slides within the second guide rail 8, driving the second bracket 5 to move synchronously. When the first slider 9 and the second slider 10 are at different heights, the awning fabric 4 is unfolded and tilted at a certain angle to the horizontal plane to cope with different raindrop directions in different wind directions.

[0066] Preferably, through holes are provided on the first slider 9 and the second slider 10, and corresponding holes and grooves are provided on the first guide rail 7 and the second guide rail 8. The through holes and the holes and grooves are matched by inserting rods to fix the first slider 9 on the first guide rail 7, and the second slider 10 on the second guide rail 8.

[0067] Specifically, first, secure the free end of the awning fabric 4 to the second support rod 501 and the second support arm 502. Then, adjust the first and second sliders 9 and 10 as needed. Insert the rod through the through-hole in the first slider 9 and into the slot in the first guide rail 7 to secure the first slider 9 to the first guide rail 7. Finally, insert the rod through the through-hole in the second slider 10 and into the slot in the second guide rail 8 to secure the second slider 10 to the second guide rail 8. The height difference between the first and second sliders 9 and 10 tilts the awning fabric 4 at a certain angle to the horizontal, providing better protection from rain in varying wind directions.

[0068] See Figure 1 In some embodiments, the retractable canopy device mounted on the portal frame further includes a first motor 11, which is provided with a waterproof cover. The first motor 11 is connected to the first slider 9 and the second slider 10 via a connecting rope 12. The first motor 11 rotates, driving the connecting rope 12, thereby driving the first slider 9 to slide in the first guide rail 7 and the second slider 10 to slide in the second guide rail 8.

[0069] Among them, a waterproof cover is provided to ensure the normal operation of the first motor 11. A winch is provided on the rotating shaft of the first motor 11, and two connecting ropes 12 are provided on the winch. The two connecting ropes are respectively connected to the first slider 9 and the second slider 10 through pulleys. By tightening and releasing the connecting rope 12 by the winch, the first slider 9 is driven to slide in the first guide rail 7, and the second slider 10 is driven to slide on the second guide rail 8. The setting of the pulley reduces the friction and noise caused by the movement of the connecting rope 12, making the movement of the connecting rope 12 more stable and smooth. The connecting rope 12 is preferably a steel wire rope. It should be noted that due to gravity, when the winch releases the connecting rope 12, the first slider 9 and the second slider 10 will slide downward. By controlling the rotation direction of the first motor 11, the position of the first slider 9 in the first guide rail 7 and the position of the second slider 10 in the second guide rail 8 are controlled.

[0070] In some embodiments, the first support rod 301 and the first slider 9, as well as the second support rod 501 and the second slider 10, are connected via a damping shaft 13. The first support rod 301 rotates on the first slider 9. The second support rod 501 rotates on the second slider 10.

[0071] The damping shaft 13 effectively prevents the first and second support rods 301, 501 from being affected by strong winds after they have been adjusted, thereby affecting the position of the awning fabric 4 and the rainproof effect. The rotation of the first support rod 301 on the first slider 9 and the rotation of the second support rod 501 on the second slider 10 are both horizontal. It should be noted that the damping shaft 13 is a well-known component and this application does not improve upon it.

[0072] See Figure 6 、 Figure 7 、 Figure 10 and Figure 11 In some embodiments, the first support rod 301, the first support arm 302, the second support rod 501, and the second support arm 502 all have a frame-type structure. The vertical cross-section of the first support rod 301 and the second support arm 501 is trapezoidal. The vertical cross-section of the first support arm 302 and the second support arm 502 is triangular. The frame-type structure provides the first support rod 301, the first support arm 302, the second support rod 501, and the second support arm 502 with better support strength, providing more stable placement conditions for the awning fabric 4.

[0073] Furthermore, the vertical cross-sections of the first support rod 301 and the second support rod 501 are regular trapezoids. The vertical cross-sections of the first support arm 302 and the second support arm 502 are isosceles triangles. This allows the first support arm 302 to be retracted and attached to the first support rod 301, and the second support arm 502 to be retracted and attached to the second support rod 501, resulting in a more compact storage space.

[0074] See Figure 9 In some embodiments, a second transverse frame 20 is disposed between the first vertical frame 102 and the second vertical frame 103. The second transverse frame 20 and the connecting frame 1 together form a rectangular frame. Grooves 14 are provided on opposing sides of the first and second vertical frames 102, 103. The ends of the second transverse frame 20 engage the grooves 14, allowing the second transverse frame 20 to slide within the grooves 14. The second transverse frame 20 is connected to the first and second sliders 9, 10 via a connecting bracket 23. The provision of the second transverse frame 20 further stabilizes the frame structure of the connecting frame 1.

[0075] like Figure 3 、 Figure 6 、 Figure 7 and Figure 9As shown, in some embodiments, the retractable canopy device mounted on the portal frame further includes a second motor 15 and a tooth plate 16, wherein the second motor 15 is gear-engaged with the tooth plate 16. One end of the tooth plate 16 passes through the first support rod 301 and is gear-engaged with the upper first gear 17 of the first support rod 301. The other end of the tooth plate 16 passes through the second support rod 501 and is gear-engaged with the upper second gear 18 of the second support rod 501. The tooth plate 16 is connected to the connecting frame 23. The second motor 15 is disposed on the second horizontal frame 20 and is used to control the expansion and retraction of the first support 3 and the second support 5.

[0076] Preferably, the tooth plate 16 is of crawler type, two rotating rollers are provided on the tooth plate 16 , and the tooth plate 16 is fixedly connected to the connecting frame 23 .

[0077] Among them, the connecting plate 2 is connected to the first slider 9 and the second slider 10 through the connecting frame 22, so that the second motor 15 is always engaged with the gear plate 16. A waterproof cover is provided on the second motor 15 to ensure the normal operation of the second motor 15. The gear on the second motor 15 is engaged with the gear on the gear plate 16, and the gear on the gear plate 16 is engaged with the first gear 17 and the second gear 18 respectively. The second motor 15 rotates, driving the gear plate 16 to rotate horizontally, and then driving the first gear 17 and the second gear 18 to rotate, thereby driving the first bracket 3 to rotate around the damping shaft 13 on the first slider 9, and the second bracket 5 to rotate around the damping shaft 13 on the second slider 10. The rotation direction of the first bracket 3 and the second bracket 5 is controlled by the rotation direction of the rotation shaft of the second motor 15.

[0078] It should be noted that the first motor 11 and the second motor 15 can be connected to a controller, which controls the opening and closing of the first motor 11 and the second motor 15 and the rotation direction of the shaft. Controller control of motors is a conventional technical means, and this application does not improve the technical solution of controller control of motors.

[0079] Working process

[0080] After the workers arrive at the construction site, they first screw the connecting plate 2 to the crossbeam of the portal frame. Then, they rotate the first support rod 3 and the second support rod 5 to the desired position, and unfold the first support arm 302 and the second support arm 502. Then, pull out the magnetic end of the awning cloth 4 in the first support rod 301 from the reel of the reel 6, close to the second support rod 301 and the second support arm 302, and use the magnetic patch to magnetically attract the second support rod 301 and the second support arm 302 so that the magnetic end of the awning cloth 4 is fixed to the second support rod 301 and the second support arm 302. The controller controls the rotation shaft of the first motor 11 to rotate, driving the winch on the first motor 11 to rotate, applying tension to the two connecting ropes 12, and the tops of the first slider 9 and the second slider 10 are subjected to force and move upward. The first slider 9 moves upward within the first guide rail 7, driving the first bracket 3 upward. The second slider 10 moves upward within the second guide rail 8, driving the second bracket 5 upward. The awning cloth 4 on the first bracket 3 and the second bracket 5 is subjected to force and moves upward. The connecting frame 22 on the second transverse frame 20 is pulled upward by the first slider 9 and the second slider 10, so that the second motor 15 on the second transverse frame 2 moves synchronously. Finally, the controller controls the rotation shaft of the second motor 15 to rotate, driving the gear plate 16 to rotate horizontally, thereby driving the first gear 17 and the second gear 18 to rotate, thereby adjusting the position of the first bracket 3 and the second bracket 5, and then adjusting the position of the awning cloth 4 until the awning cloth 4 reaches the desired position.

[0081] The canopy device of the present invention can be quickly deployed when construction is needed, and the shielding height and shielding range of the canopy can be controlled by a controller as needed, providing effective rain protection and avoiding the impact of rain on the construction site; it can be folded up when not in use, does not take up space on the construction site, and does not interfere with the normal operation of other equipment.
