The maximum moving interval distance of the overall rotating movement mechanism is 40cm. When it is at the maximum moving distance, the block 2003 is in relative contact, which facilitates the packing of prestressed steel strands with too small diameters.

[0026] like Figure 4 and Figure 5As shown, the adjustment device 20 for adjusting the overall height is installed above the top of the connecting block group 8, and the adjustment device 20 includes a mounting frame 2001, a sixth slide groove 2002, a block 2003, a rubber pad 2004, a ball nut 2005, a sleeve 2006, a slide plate 2007, a second mounting groove 2008, a limit rod 2009, a limit groove 2010, a pull ring 2011, a fiber belt 2012, a hook 2013, a screw rod 2014 and a rotating motor 2015. The sixth slide groove 2002 is opened through the right side of the mounting frame 2001, and the bottom of the mounting frame 2001 is fixed to the top of the connecting block group 8. The rubber pad 2004 is inlaid and fixed on the right side of the block 2003, and the left side of the block 2003 is connected to the mounting frame 200 1 is fixedly connected to the right side of the connecting block group 8, and a sliding sleeve 2006 is welded and fixed in front of the ball nut 2005. The connection shape of the ball nut 2005 and the sliding sleeve 2006 is in a "cross" shape, which is convenient for adjusting the slide plate 2007 up and down or left and right, so as to avoid that the slide plate 2007 can only be adjusted up and down or left and right, thereby affecting the packaging of prestressed steel strands of different diameters. In addition, the connection shape of the ball nut 2005 and the sliding sleeve 2006 is in a "cross" shape, which not only reflects the simplicity and practicality of the connection between the two, but also reflects the economy and symmetry of the connection between the two. A second installation groove 2008 is provided at the bottom of the slide plate 2007, and a limiting groove 210 is provided at the top of the limiting rod 2009. A fiber belt 2012 is fixed at the bottom of the pull ring 2011, a hook 2013 is fixed at the bottom of the fiber belt 2012, the pull ring 2011 passes through the limit rod 2009 and is movably connected to the limit groove 2010, the limit rod 2009 is fixed on both sides of the inner wall of the second installation groove 2008, the slide plate 2007 passes through the sliding sleeve 2006 and the sixth slide groove 2002 on both sides and extends to both sides of the installation frame 2001, the bottom of the screw rod 2014 passes through the top outer wall of the installation frame 2001 and the ball nut 2005 and extends to the inside of the installation frame 2001, and the bottom of the screw rod 2014 is rotatably connected to the bottom end of the installation frame 2001, the top of the screw rod 2014 is fixedly connected to the output end of the rotating motor 2015, and the rotating motor 2015 is fixed by a hexagonal bolt At the top of the installation frame 2001, the rotating motor 2015 is electrically connected to the controller through wires. The rotating motor 2015, the screw rod 2014, the ball nut 2005 and the sleeve 2006 constitute a lifting mechanism, and the lifting distance range of the lifting mechanism is 5-55cm. The rotating motor 2015 drives the screw rod 2014 to move so as to adjust the height between the slide plate 2007 and the top of the prestressed steel strand, so as to facilitate the packaging of the prestressed steel strand. The moving interval distance of the overall lifting mechanism is 50cm. When it is in the maximum moving interval, the bottom of the slide plate 2007 contacts the top of the block 2003. If the maximum moving interval distance is exceeded, it is easy to cause the bottom of the slide plate 2007 and the top of the block 2003 to be squeezed.This can easily cause the slide plate 2007 to be squeezed and deformed, and the prestressed steel strands cannot be packaged.

During the movement of the first rack 7, it moves to the right inside the second slide slot 5, and the first rack 7 moves relative to the F block 4 during the movement. At the same time, during the movement of the first rack 7, the connecting block group 8 moves in the same direction. During the movement of the connecting block group 8, the first slide slot 3, the second slide slot 5 and the third slide slot 6 are relatively moved. During the movement of the connecting block group 8, the installation frame 2001 is driven to move on the right side. During the movement of the installation frame 2001, the sliding sleeve 2006 is driven to move in the same direction. During the movement of the sliding sleeve 2006, it moves on the right side of the slide plate 2007. When the second output motor 18 is working, it drives the second gear 19 to move. The second gear 19 moves During the movement, the second rack 12 moves relative to the first mounting groove 2, and the second gear 19 drives the second rack 12 to move to the left during the movement. During the movement of the second rack 12, it moves to the left inside the fourth slide groove 10, and the second rack 12 moves relative to the mounting block 9 during the movement.

When the pull ring 2011 contacts the limit groove 2010, the pull ring 2011 stops moving downward, and then the hook 2013 is manually held to drive the fiber belt 2012 to wrap around the two sides above the prestressed steel strand. When the two sides of the prestressed steel strand are wrapped, the hook 2013 is manually contacted with the limit groove 2010 again. The above steps and procedures are repeated in sequence to move the prestressed steel strand to the corresponding position through the overall equipment and remove the prestressed steel strand from the equipment. This completes the entire operation, and the contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.
