Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, a guide and guard device of a rolling mill with a variable guide and guard port comprises a guide and guard body 1 and a support arm 2, wherein the support arm 2 is fixedly installed in the guide and guard body 1, an intermediate shaft 3 is movably installed in one end of the support arm 2, transverse support plates 4 are annularly installed at the upper end and the lower end of the intermediate shaft 3, a shaft column is fixedly connected between the upper transverse support plate 4 and the lower transverse support plate 4 through a nut, a guide wheel 5 is movably connected to the shaft column between the transverse support plates 4, a fixed disc 7 is fixedly installed on the upper surface of the support arm 2, a fixed screw 8 is movably connected to the fixed disc 7, and a rotating head 9 is movably connected to the center of the fixed disc 7.

Wherein, the fixed cover 6 that has cup jointed on the nut of jack-post on the top of horizontal backup pad 4, the shape after the jack-post is connected to the shape of the lower surface inner groove shape of fixed cover 6 and nut to the adaptation, entangle the nut of fixed action through fixed cover 6 like this, guarantee can not take place the not hard up of nut under long-time high strength work and have the continuous vibration effect to guarantee guide pulley 5's connection stability.

Wherein, the logarithm of horizontal backup pad 4 is 3 ~ 5 pairs, and every 5 shapes inequality of guide pulley of movable mounting between every pair of horizontal backup pad 4, through the jackshaft 3 on install many pairs of horizontal backup pad 4 and swing joint have the guide pulley 5 of different shapes between horizontal backup pad 4, can make jackshaft 3 rotatory when needing to change the port shape, let the guide pulley 5 of different shapes rotatory corresponding position of going on the guide effect.

Wherein, rotate the head 9 and run through fixed disc 7 and jackshaft 3's top fixed connection, can rotate the head 9 through manual rotation like this and drive jackshaft 3 rotatory to the realization is as required to the adjustment of the position of different shape guide wheels 5.

Wherein, clamping screw 8 runs through support arm 2 and fixed disc 7 embedding and is connected to horizontal backup pad 4 top, and when the guide pulley 5 pivoted that will use corresponds the position, through clamping screw 8's bottom threaded connection to horizontal backup pad 4's top, fix horizontal backup pad 4 position to guaranteed that guide pulley 5 can not take place the rotation of relative jackshaft 3 when using.

The working principle is as follows: during the use, when need change the guide pulley 5 of different shapes, at first twist the clamping screw 8 upwards for clamping screw 8's bottom breaks away from and is connected with the upper end of horizontal backup pad 4, then manual rotation rotates and rotates head 9, it is rotatory to rotate head 9 and drive jackshaft 3, jackshaft 3 then drives horizontal backup pad 4 and the synchronous revolution of the guide pulley 5 of installing on it, twist all clamping screw 8 to the top of horizontal backup pad 4 again after rotating the guide pulley 5 that will use to horizontal position, accomplish the change to the guide pulley shape.
