Description

Technical Field

[0001] This utility model relates to the field of side-turn door technology, and in particular provides a side-turn door with a traction balance synchronous drive structure. Background Technology

[0002] Side-turn doors are a common type of industrial door, typically consisting of two large door panels that open in opposite directions. Normally, each door panel requires a separate drive mechanism. However, even with identical drive mechanisms and speeds, discrepancies in the drive of the two panels can occur, causing them to open and close asynchronously. Furthermore, because industrial doors are generally tall with a high center of gravity, they are prone to tilting, leading to gaps between the lower edge of the door and the lower guide rail. When the door is driven solely by the lower drive wheels, slippage may occur, affecting the door's opening and closing. Utility Model Content

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0030] refer to Figures 1-13 This utility model provides a side-turning door with a traction balance synchronous drive structure, including a traction balance synchronous drive structure and a first door leaf 1 and a second door leaf 2 set on a side-turning track. The first door leaf 1 and the second door leaf 2 each include an active door leaf 3 and multiple driven door leaves 4 hinged together. The two active door leaves 3 are set close to each other. Each active door leaf 3 is provided with two bottom guide wheels 9 below and a top guide wheel 10 above. The traction balance synchronous drive structure includes a drive structure and a traction balance structure. Each active door leaf 3 is provided with a drive structure. The traction balance structure includes a first traction balance rope 5, a first drum 6, a second traction balance rope 7 and a second drum 8. The first drum 6 and the second drum 8 are respectively set on the active door leaves 3 of the first door leaf 1 and the second door leaf 2. The drive structure on the first door leaf 1 is connected to the first drum 6, and the drive structure on the second door leaf 2 is connected to the second drum 8.

[0031] One end of the first traction balance rope 5 is connected to the lower end of the wall near the first door leaf 1, extends horizontally and passes around a bottom guide wheel 9 of the first door leaf 1, then winds upwards around the first drum 6 several times, continues upwards around the top guide wheel 10 of the first door leaf 1, extends horizontally and passes around the top guide wheel 10 of the second door leaf 2, then winds downwards around the second drum 8 several times, continues downwards around a bottom guide wheel 9 of the second door leaf 2, extends horizontally and is connected to the lower end of the wall near the second door leaf 2.

[0032] One end of the second traction balance rope 7 is connected to the upper end of the wall near the first door leaf 1, extends horizontally and wraps around the top guide wheel 10 of the first door leaf 1, then winds downwards around the first drum 6 several times, continues downwards around the other bottom guide wheel 9 of the first door leaf 1, extends horizontally to the other bottom guide wheel 9 of the second door leaf 2, winds upwards around the second drum 8 several times, continues upwards around the top guide wheel 10 of the second door leaf 2, and extends horizontally to connect with the wall near the second door leaf 2.

[0033] In the opening process of the side revolving door provided by this utility model, which is equipped with a traction balance synchronous drive structure, the first door leaf 1 and the second door leaf 2 are driven by the drive structure to rotate the first drum 6 and the second drum 8, respectively. When the first drum 6 rotates clockwise and the second drum 8 rotates counterclockwise, the portion of the first traction balance rope 5 located on the lower side of the first drum 6 and the second drum 8 shortens and the portion on the upper side lengthens, causing the two bottom guide wheels 9 connected to the first traction balance rope 5 on the two active door leaves 3 of the first door leaf 1 and the second door leaf 2 to move away from each other; the portion of the second traction balance rope 7 located on the lower side of the first drum 6 and the second drum 8 lengthens and the portion on the upper side shortens, causing the two bottom guide wheels 9 connected to the second traction balance rope 7 on the two active door leaves 3 of the first door leaf 1 and the second door leaf 2 to move away from each other. Due to the mutual restraint of the first traction balance rope 5 and the second traction balance rope 7, the first door leaf 1 and the second door leaf 2 are synchronously moved away from each other, and the side revolving door opens.

[0034] When the first drum 6 rotates counterclockwise and the second drum 8 rotates clockwise, the portion of the first traction balance rope 5 located on the lower side of the first drum 6 and the second drum 8 extends and the portion on the upper side shortens, causing the two bottom guide wheels 9 connected to the first traction balance rope 5 on the two active door panels 3 of the first door panel 1 and the second door panel 2 to move closer to each other; the portion of the second traction balance rope 7 located on the lower side of the first drum 6 and the second drum 8 shortens and the portion on the upper side extends, causing the two bottom guide wheels 9 connected to the second traction balance rope 7 on the two active door panels 3 of the first door panel 1 and the second door panel 2 to move closer to each other. Due to the mutual restraint of the first traction balance rope 5 and the second traction balance rope 7, the first door panel 1 and the second door panel 2 move closer to each other synchronously, and the side door closes.

[0035] As a specific implementation of the drive structure, the drive structure includes a drive motor 11, a drive sprocket 12, a driven sprocket 13, and a drive chain 14. The output end of the drive motor 11 is connected to the drive sprocket 12. The driven sprocket 13 on the first door leaf 1 is coaxially connected to the first drum 6. The driven sprocket 13 on the second door leaf 2 is coaxially connected to the second drum 8. The drive chain 14 is sleeved between the drive sprocket 12 and the driven sprocket 13.

[0036] During the operation of the drive structure, the output end of the drive motor 11 drives the active drive sprocket 12 to rotate. The active drive sprocket 12 drives the driven drive sprocket 13 to rotate through the drive chain 14. Since the driven drive sprocket 13 is coaxially connected with the corresponding first drum 6 and second drum 8, it drives the first drum 6 and second drum 8 to rotate, thereby winding or unwinding the first traction balance rope 5 and the second traction balance rope 7 onto the first drum 6 and second drum 8.

[0037] To control the entry angle of the first traction balance rope 5 and the second traction balance rope 7 and make the traction process smoother, as an improvement to the technical solution, first guide wheels 19 are provided on both sides of the inner wall of the active door leaf 3 between the drive motor 11 of the first door leaf 1 and the first drum 6, and on both sides of the inner wall of the active door leaf 3 between the drive motor 11 of the second door leaf 2 and the second drum 8; second guide wheels 20 are provided on both sides of the inner wall of the middle part of the active door leaf 3 of the first door leaf 1 and the second door leaf 2, and the first guide wheels 19 and the second guide wheels 20 are for the first traction balance rope 5 and the second traction balance rope 7 at corresponding positions to pass around.

[0038] The first traction balance rope 5 is supported and guided by a set of first guide wheels 19 and second guide wheels 20 that are far apart inside the two active door panels 3, while the second traction balance rope 7 is supported and guided by a set of first guide wheels 19 and second guide wheels 20 that are close to each other.

[0039] In order to prevent the first traction balance rope 5 and the second traction balance rope 7 from interfering with each other during the winding and unwinding process, as an improvement to the technical solution, both the first drum 6 and the second drum 8 are double drum structures, which are respectively used for winding the first traction balance rope 5 and the second traction balance rope 7.

[0040] The top guide wheel 10 has a dual-wheel structure, through which the first traction balance rope 5 and the second traction balance rope 7 pass respectively.

[0041] To facilitate the connection of the first traction balance rope 5, balance rope fixing seats 15 are provided at the lower ends of both side walls. Guide blocks 16 are provided on the ground below the balance rope fixing seats 15. The two ends of the first traction balance rope 5 pass through the corresponding guide blocks 16 and are connected to the corresponding balance rope fixing seats 15. At least one end of the first traction balance rope 5 is provided with a balance rope spiral buckle 17. The tension of the first traction balance rope 5 is adjusted by the balance rope spiral buckle 17.

[0042] To facilitate the connection of the second traction balance rope 7, a balance rope fixing seat 15 is also provided at the upper end of one side of the wall, and a balance rope deflector 18 is provided at the upper end of the other side of the wall. One end of the second traction balance rope 7 is connected to the balance rope fixing seat 15 at the upper end of the wall, and the other end passes around the balance rope deflector 18 and is connected downward to the balance rope fixing seat 15 at the lower end of the same side of the wall. A balance rope spiral buckle 17 is also connected to the lower end of the second traction balance rope 7.

[0043] The second traction balance rope 7 is brought to a position close to the ground by the balance rope steering wheel 18, so that the operator can adjust the tension of the second traction balance rope 7 by means of the balance rope screw buckle 17.

[0044] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
