Through the use of the half-toothed ring meshing with the gear and the limiting ring for limiting the first half grinding ring, the first half grinding ring and the second half grinding ring make an arc motion, so that the sandpaper rubs against the surface of the steel rod. Therefore, by using the second motor to drive the rotating shaft to make periodic and repeated motions, the sandpaper can grind the steel rod back and forth, and the first motor drives the threaded rod to rotate. Since the slider can only slide in the cavity, the positions of the first half grinding ring and the second half grinding ring on the steel rod can be changed, thereby achieving the effect of grinding various parts of the steel rod.

The interior of the installation cavity 2007 is rotatably connected with a rotating shaft. A second motor 2005 is installed on the outside of the connecting disk 2004. The output end of the second motor 2005 is transmission-connected to the rotating shaft. A gear 2006 is installed on the outside of the rotating shaft. A connecting strip 2009 is symmetrically installed on the top of the connecting disk 2004. A limit ring 2010 is installed on the top of the connecting strip 2009. A first half grinding ring 2012 slides between the limit rings 2010. A semi-toothed ring 2015 is installed on the outside of the first half grinding ring 2012. The semi-toothed ring 2015 is meshed with the gear 2006. The first half grinding ring 2012 is meshed with the gear 2006. A second half grinding ring 2013 is hinged on one side of the grinding ring 2012, and the other sides of the first half grinding ring 2012 and the second half grinding ring 2013 can be fixedly connected together. Sandpaper is adhered to the inner walls of the first half grinding ring 2012 and the second half grinding ring 2013. The steel rod 1005 lifted by the crane can be placed on a pair of support frames 1004. At this time, the sandpaper in the first half grinding ring 2012 contacts the lower half of the steel rod 1005.

[0032] Embodiment 3 of the special steel rod surface grinding device of the utility model

[0033] Reference Figure 1-Figure 4 Specifically, an arc-shaped fixing groove 1006 is opened on the top of the support frame 1004, and an anti-skid pad is adhered to the inside of the fixing groove 1006. When the first half grinding ring 2012 and the second half grinding ring 2013 rotate and grind the steel rod 1005, the weight of the steel rod 1005 itself is used to prevent it from being driven to move by the first half grinding ring 2012 and the second half grinding ring 2013. At the same time, under the action of the anti-skid pad, the friction between the steel rod 1005 and the arc-shaped fixing groove 1006 can be increased, thereby further limiting the movement of the steel rod 1005.

[0034] Specifically, the working principle of the special steel rod surface grinding device is as follows: when in use, the steel rod 1005 lifted by the crane can be placed on a pair of support frames 1004, and the second half grinding ring 2013 is closed and fixed with screws and nuts. If the sandpaper does not contact the steel rod 1005 at this time, it is necessary to raise the height of the sandpaper until it contacts the outer side of the steel rod 1005. When the second motor 2005 is started, it will drive the shaft to drive the gear 2006 to rotate, through the half gear ring 2015 meshing with the gear 2006, and the limit ring 2012 that limits the first half grinding ring 2012. 0, the first half grinding ring 2012 and the second half grinding ring 2013 make an arc motion, so that the sandpaper rubs against the surface of the steel rod 1005. Therefore, the second motor 2005 drives the rotating shaft to make periodic repeated motions, so that the sandpaper can grind the steel rod 1005 back and forth. The first motor drives the threaded rod 2001 to rotate. Since the slider 2002 can only slide in the cavity 1003, the positions of the first half grinding ring 2012 and the second half grinding ring 2013 on the steel rod 1005 can be changed, so that various parts of the steel rod 1005 can be grinded.
