[0024] Embodiment 1: A quick - closing structure of a gate, as Figures 1 - 5As shown in the figure, it includes a support frame 1, a guide cylinder 3 installed at the upper end of the support frame 1, and an adjustable support rod 2 inserted inside the support frame 1 for driving support. The adjustable support rod 2 extends outside the support frame 1, and the adjustable support rod 2 is inserted into the guide cylinder 3. A number of meshing support rings 4 are installed in a partial area on the outside of the adjustable support rod 2. The meshing support rings 4 are all located inside the support frame 1. Two rotation gears 6 are arranged at symmetrical positions on the outside of the meshing support ring 4. The two rotation gears 6 are simultaneously meshed with the meshing support ring 4, and a wire reel 9 is arranged on each of the opposite sides of each rotation gear 6. A connecting steel cable 11 is installed on the circumferential surface of the middle of the wire reel 9. One end of the connecting steel cable 11 away from the wire reel 9 is installed with an arc-shaped support frame 12. The arc-shaped support frame 12 is installed on the outside of the adjustable support rod 2. A rotating column 8 for rotating support is inserted into one rotation gear 6 and the two wire reels 9 on both sides at the same time. One end of the rotating column 8 is inserted with a driven gear 13. There are at least two driven gears 13, and the two driven gears 13 are meshed with each other. The driven gear 13 is meshed with a driving gear 14. A rotating disc 16 and a driving module 18 for rotating support are arranged on one side of the driving gear 14, and the driving module 18 is an external type.
[0025] When the device is started, it runs through the driving module 18, driving the 14 at its output end to rotate simultaneously. And the driving module 18 can be set as a hoist of models such as QSL and QSY or other driving devices, and it is prior art, so it is not described in detail in this embodiment. Thus, the driven gear 13 rotates under the driving support of the driving gear 14, making the two driven gears 13 on both sides rotate synchronously, making the two rotating columns 8 on both sides rotate in opposite directions synchronously, making the two rotation gears 6 and the wire reels 9 on both sides rotate following the rotating columns 8 at the same time. When the rotation gear 6 rotates, under the meshing connection between the meshing support ring 4 and the rotation gear 6, the adjustable support rod 2 can be adjusted from the vertical position. When the wire reel 9 rotates, the connecting steel cable 11 can be wound and unwound. Under the connection of the arc-shaped support frame 12, the adjustable support rod 2 is driven to move. Thus, through the combined use of multiple transmission components, the adjustable support rod 2 can be supported in multiple directions by synchronously running the gear meshing transmission and the rope winding and unwinding from the outside of the adjustable support rod 2, improving the speed when the adjustable support rod 2 is closed and opened, and at the same time ensuring its stability.
[0026] As Figures 1 - 5 shown, a number of anti-slip rings 5 for anti-slip clamping support are installed on both opposite sides of the meshing support ring 4, and a number of anti-slip pad strips 7 for anti-slip clamping support are installed on both opposite sides of the outer teeth of the rotation gear 6. The anti-slip rings 5 and the anti-slip pad strips 7 are distributed in a staggered manner.
[0027] While the meshing support ring 4 is in meshing transmission with the rotating gear 6, based on the mutual contact between the anti-slip ring 5 and the anti-slip strip 7, an anti-slip effect is provided at the acting position between the meshing support ring 4 and the rotating gear 6, ensuring the stability of their meshing transmission connection, improving the fastening and reliability of the position during the movement and limit of the adjusting support rod 2, and protective components are provided on both opposite sides of the meshing support ring 4 and the teeth, ensuring that protective support can be carried out during the closing and opening movement of the adjusting support rod 2, and improving the comprehensiveness of the protection during its movement.
[0028] As Figures 1 - 5 shown, there are at least two arc-shaped support frames 12, and the two arc-shaped support frames 12 are in opposite positions, and the arc-shaped support frames 12 are installed at the upper end of the uppermost meshing support ring 4, and connecting steel cables 11 are installed at both opposite ends of each arc-shaped support frame 12.
[0029] Firstly, under the annular support of multiple meshing support rings 4 itself, the teeth on the meshing support ring 4 on the same horizontal plane can be in contact with the teeth on the two side rotating gears 6 at the same time. Under the mutual transmission and support of the meshing support ring 4 itself for the meshing pressure, the support stability during meshing is ensured. Secondly, under the limit guidance of the two end meshing support rings 4, the movement range of the adjusting support rod 2 can be controlled within the height of the support frame 1, ensuring the stability of the distance during the movement and closing of the adjusting support rod 2, ensuring the stability and accuracy of the movement distance of the gate closing component, and protecting the stability of the position between the gate and the closing component. Finally, under the simultaneous support of the two side arc-shaped support frames 12 and the uppermost meshing support ring 4, the reliability of its own strength during limiting is ensured. At the same time, the connecting steel cables 11 are arranged at both ends of the arc-shaped support frames 12. By exerting force at both ends simultaneously, the force on the outside of the adjusting support rod 2 can be centered, ensuring the precise stability of the position of the adjusting support rod 2 during movement and fixed use.
[0030] Embodiment 2: A rapid closing structure for a gate, as Figures 1 - 5 shown, a guide rail 10 for guiding and supporting is installed on the middle annular surface of the wire reel 9. The guide rail 10 is spirally distributed and is used for the rotational guidance of the connecting steel cable 11.
[0031] When the wire reel 9 winds and unwinds the connecting steel cable 11, under the guiding support of the internal guide rail 10 thereof, the connecting steel cable 11 can be spirally wound to prevent it from crossing.
[0032] As Figures 1 - 5 shown, a number of anti-slip strips 7 are installed on both opposite sides of the teeth on the outer sides of the driven gear 13 and the driving gear 14, and the meshing teeth on the two driven gears 13 are anti-slip through the anti-slip strips 7 on both sides.
[0033] Under the anti-slip support of the anti-slip strip 7, when the two driven gears 13 are engaged in transmission and when the driven gear 13 is engaged in transmission with the driving gear 14, an anti-slip effect is achieved, the support between the transmission components is improved, the situation of sliding is effectively prevented, and the support performance of the device during use is improved.
[0034] As Figures 1 - 5 shown, a rotating rod 15 is inserted in the middle of the driving gear 14, a rotating disc 16 is installed at one end of the rotating rod 15, the rotating rod 15 is inserted into and extends into a support cylinder 17, a driving module 18 is provided at one end of the support cylinder 17, and the other end of the rotating rod 15 is installed at the output end of the driving module 18.
[0035] The two rotating columns 8 are rotatably installed on the inner wall of the support frame 1, and the rotating gear 6 and the driven gear 13 are both rotatably installed inside the support frame 1.
[0036] Under the transmission support of the rotating rod 15 and under the driving support of the rotating disc 16 and the driving module 18, the device can select manual or automatic control modes, ensuring the diversity of its control modes. At the same time, arranging driving components such as the rotating gear 6 and the driven gear 13 inside the support frame 1 can protect the stability and safety of the internal driving components during operation.
[0037] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
