The cross section of described guide rail is I-shaped, and its lower panel is fixed on the base; Dull and stereotyped four jiaos all have vertical wheel shaft, and the upper end of vertical wheel shaft is fixed on the flat board, and stretch out under flat board the lower end.Vertical wheel shaft lower end all is fixed with horizontal wheel shaft, laterally on the wheel shaft bottom roller is arranged all, and this bottom roller is between the upper and lower panel of I-shaped guide rail riser one side and can rolls along lower panel.
At vertical wheel shaft and lateral wheel between centers connecting plate is arranged, this connecting plate is a strip, and it is connected with the lower end of vertical wheel shaft the top longitudinally mutually.Laterally an end of wheel shaft is fixed on the connecting plate, and the other end stretches between the upper and lower panel of I-shaped guide rail riser one side, and described bottom roller is installed on the horizontal wheel shaft between the upper and lower panel that stretches into I-shaped guide rail riser one side.
Being between dull and stereotyped edge and the I-shaped guide rail of upper roller on the vertical wheel shaft upper roller arranged, one side also can be rolled along the wallboard between dull and stereotyped and the I-shaped guide rail.
Take such scheme, have the following advantages:
By such scheme as can be seen,, on two guide rails flat board is arranged, the dull and stereotyped four jiaos following roller that cooperates with two guide rails that all has because the bottom inside of two wallboards all has guide rail.Reduction box is all arranged on two flat boards, output shaft is all arranged on two reduction boxes, this two output shaft is positioned opposite and is on the same axis, during work, is clamped in by strip between two fixed disks of two output shaft ends.Hydraulic jack is all arranged on Unit two, and the piston rod of hydraulic jack is parallel with two guide rails, and its two ends are connected on flat board one end and base away from output shaft.Flexible by two hydraulic cylinder piston rods can drive advancing or retreating of reduction box on flat board, the flat board and reduction gearbox output shaft, makes the fixed disk between two output shafts can move left and right, thereby realized by the rolling centerline adjustment of strip.Compare with traditional manual operations, not only reduced operator's labour intensity, and reduced rolling centre deviation, improved rolling quality.
