By setting the rotating shaft 222, the worm 225, the worm wheel 226 and the gear 221, the rotating shaft 222 is rotated, the rotating shaft 222 drives the gear 221 to rotate, and the gear 221 drives the rack 223, the mounting plate 220 and the roller 224 to move upward. By rotating the worm 225, the worm 225 drives the worm wheel 226 to rotate, so that the worm wheel 226 drives the rotating shaft 222 to rotate, and the self-locking property of the worm wheel 226 and the worm 225 is utilized to make the position of the rack 223 relatively stable.
使用时，转动锥齿环215，锥齿环215驱动两个锥齿轮214转动，锥齿轮214驱动螺杆213移动，螺杆213带动安装盒217、连接杆216和夹板211移动，使夹板211对钢筋笼顶端外表面进行夹持固定，通过安装盒217带动齿条223、安装板220、伸缩杆228和辊轮224移动，利用弹簧229的弹力，使辊轮224外表面挤压钢筋笼，混凝土向套筒1内部浇筑时，转动蜗杆225，蜗杆225驱动蜗轮226转动，使蜗轮226带动转轴222和齿轮221同步转动，齿轮221驱动齿条223和安装板220和辊轮224向上移动，使辊轮224沿钢筋笼外表面向上移动。When in use, the bevel gear ring 215 is rotated, and the bevel gear ring 215 drives the two bevel gears 214 to rotate, and the bevel gear 214 drives the screw 213 to move, and the screw 213 drives the installation box 217, the connecting rod 216 and the clamping plate 211 to move, so that the clamping plate 211 clamps and fixes the outer surface of the top end of the steel cage, and drives the rack 223, the mounting plate 220, the telescopic rod 228 and the roller 224 to move through the installation box 217, and utilizes the elastic force of the spring 229 to make the outer surface of the roller 224 squeeze the steel cage. When concrete is poured into the sleeve 1, the worm 225 is rotated, and the worm 225 drives the worm wheel 226 to rotate, so that the worm wheel 226 drives the rotating shaft 222 and the gear 221 to rotate synchronously, and the gear 221 drives the rack 223, the mounting plate 220 and the roller 224 to move upward, so that the roller 224 moves upward along the outer surface of the steel cage.
