In China, many ancient towns and most large cities still retain some ancient buildings. With the prevalence of modern buildings, there are fewer and fewer ancient buildings, and most of them are damaged or even collapsed due to disrepair.

[0003] In order to preserve historical traces and protect ancient buildings, it is often necessary to repair ancient buildings that pose safety risks and protect them for the purpose of repair. When repairing ancient buildings, it is necessary to adopt antique building methods to protect the original appearance of the ancient buildings to the greatest extent and preserve the historical culture and atmosphere.

[0004] However, when repairing ancient wooden buildings, it is necessary to support the columns of the ancient wooden buildings. The supporting structures are mostly rods, which are heavy and cumbersome to operate, and may cause damage to the columns of the ancient wooden buildings during installation. Therefore, it does not meet the existing needs. In this regard, we propose an inward restraint device for ancient wooden structures. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] like Figures 1 to 5 As shown, an inward binding device for an ancient wooden structure building, a winding motor 7 is fixed inside the central block 1, a transmission gear 6 is fixed at the end of the output shaft of the winding motor 7, four rotationally symmetrical winding gears 5 are meshed on the outer side of the transmission gear 6, a rotating block 8 is fixed through the winding gear 5, the bottom end of the rotating block 8 is rotatably connected to the central block 1, a transmission shaft 9 is installed through the top of the rotating block 8, a drum shaft 4 is installed on the outer side of the top of the transmission shaft 9, a winding roller 3 is fixed on the outer side of the drum shaft 4, a binding belt 2 is wound around the outer side of the winding roller 3, one end of the binding belt 2 is fixed to the outer side of the winding roller 3, and the other end of the winding roller 3 passes through the side wall of the central block 1 and is detachably fixed to the outer side of the central block 1, the winding motor 7 is used to drive the transmission gear 6, the winding gear 5, and the drum shaft 4 to rotate, so that the winding roller 3 winds up the binding belt 2, and the wound binding belt 2 is used to apply an inward pulling force to the column of the wooden structure ancient building to prevent the column of the wooden structure ancient building from tilting outward.

[0023] Two plug-in rods 12 are fixed inside the bottom end of the drum shaft 4, and the bottom ends of the plug-in rods 12 are plugged into the top end of the transmission shaft 9. The plug-in rods 12 connect the transmission shaft 9 with the drum shaft 4, so that when the transmission shaft 9 rotates under force, the transmission shaft 9 drives the drum shaft 4 to rotate simultaneously through the plug-in rods 12.

[0024] An annular groove 13 is provided on the outer surface of the transmission shaft 9, and two guide grooves 14 are installed at the bottom of the annular groove 13. A rotating connecting block 11 is slidably installed on the inner side of the guide groove 14. The rotating connecting block 11 is fixed on the inner side of the rotating block 8. The height of the annular groove 13 is consistent with that of the guide groove 14. The height of the rotating connecting block 11 is the same as that of the annular groove 13 and the guide groove 14. The transmission shaft 9 and the rotating block 8 are connected by the rotating connecting block 11, so that when the winding gear 5 drives the rotating block 8 to rotate, the transmission shaft 9 rotates simultaneously with the rotating block 8.

[0025] The bottom end of the transmission shaft 9 passes through the bottom end of the center block 1. The bottom end of the transmission shaft 9 is provided with a through plug hole 10. The transmission shaft 9 slides and rubs with the rotating block 8. Without external force intervention, there will be no relative displacement between the transmission shaft 9 and the rotating block 8. After the transmission shaft 9 is pulled downward, the rotating connecting block 11 enters the annular groove 13. At this time, the transmission shaft 9 loses connection with the rotating block 8. When the transmission shaft 9 rotates, it will only drive the drum shaft 4 to rotate but will not drive the rotating block 8 and the winding gear 5 to rotate.

[0026] Working principle: first, one end of the binding strap 2 is put on the outside of the supporting column of the wooden ancient building, and then the end of the binding strap 2 is fixed to the outer surface of the center block 1. After all the binding straps 2 are put on the outside of the wooden ancient building, the power of the reeling motor 7 is turned on and started. The reeling motor 7 drives the transmission gear 6 to rotate so that the four reeling gears 5 rotate clockwise at the same time. At this time, the reeling gear 5 drives the rotating block 8 to rotate, and the rotating block 8 drives the transmission shaft 9 and the plug-in rod 12 to rotate through the rotating connecting block 11. At this time, the transmission shaft 9 drives the drum shaft 4 and the reeling drum 3 to rotate through the plug-in rod 12, and the reeling drum 3 reels the binding strap 2. The reeled binding strap 2 applies a pulling force to the supporting column of the wooden ancient building in the direction of the center block 1, so that the supporting column of the wooden ancient building cannot tilt outward, thereby ensuring the stability of the wooden ancient building, convenient operation and short construction time, effectively improving the construction efficiency, and at the same time will not cause damage to the column of the wooden ancient building.
