A frame 4 is detachably installed on the upper part of the guide rails 3 to support the panel of the arc-shaped gate 5. Each guide rail 3 has adjustable tie rods 6 at both ends along its length. The lower end of the adjustable tie rod 6 is detachably connected to the guide rail 3, and the upper end is welded to the edge of the panel of the arc-shaped gate 5. The frame 4 and the adjustable tie rods 6 position the panel of the arc-shaped gate 5, facilitating welding of the arc-shaped gate 5. When welding the flat gate 8 and the gate slot embedded parts, the frame 4 and the adjustable tie rods 6 are removed, and multiple clamp bolt assemblies 7 are used to fix the edge components of the gate (such as the panel, flanges, side rails, etc.) to the guide rails 3.

[0030] SeeFigure 5 The guide rail 3 is provided with a continuous T-shaped groove 3-1, which facilitates the installation of the bracket 4, adjustable rod 6, and adjustment of the position of the bracket 4 and adjustable rod 6 for welding the arc gate 5.

The upper clamping plate 7-1 is placed flat on the upper part of the guide rail 3, and the lower clamping plate 7-2 is placed in the T-shaped groove 3-1 on the upper part of the guide rail 3. The locking bolt 7-3 passes through the through holes on the lower clamping plate 7-2 and the upper clamping plate 7-1 in sequence and is then screwed into the locking nut 7-4. The upper part of the upper clamping plate 7-1 is fixed with either a high support rod 4-1 or a low support rod 4-2. Tightening the locking nut 7-4 can fix the jig 4 on the guide rail 3, and loosening the locking nut 7-4 can allow the clamping bolt assembly 7 and the jig 4 to slide along the guide rail 3, thereby adjusting the position of the jig 4.

Their proximal ends are threaded into both ends of the threaded sleeve 6-2, and their distal ends are hinged to the base 6-3 and the pull plate 6-4, respectively. By rotating the threaded sleeve 6-2, the distance between the base 6-3 and the pull plate 6-4 can be changed, thereby adjusting the position of the edge of the panel of the arc gate 5.

[0035] The positive threaded lead screw 6-1, the negative threaded lead screw 6-5, and the threaded sleeve 6-2 constitute the rigging helical buckle, which facilitates procurement and manufacturing.
