The Heat Working Rolls roll change generally adopts roll change buggy to carry out roll change.At the head of roll change buggy a hook that electric cylinder drives has been installed, hook and the decoupling device of hook and working roll bearing block hook groove are finished by electric cylinder.The decoupling device of hook (rising) and hook (decline) accurately detect by position detecting device.When control program driving electric cylinder piston rod travelled forward, piston rod drove the decline (hook) of the hook that is attached thereto, and when switch detects in the hook insertion working roll bearing block hook groove, made the electric cylinder stop motion by the PLC control program; Otherwise hook rises, and hook and working roll bearing block hook groove break away from (decoupling device).Roll change buggy inserts (hook) behind the working roll bearing block hook groove by hook, can drive working roll and advance or retreat and carry out roll change.Former roll change buggy hook position detecting device is arranged as: weld vertically upward test rod on the horizontal electric cylinder piston rod, the electric cylinder piston rod sleeve is provided with the rectangle perforate of long 180mm, a limit switch is respectively installed at the perforate two ends, by test rod forward, motion is touched limit switch and detected the hook position backward.Often electric hydaulic cylinder active force is large and test rod is severed, and can't detect the physical location of hook, causes hook to move, and automatically roll change can only be lifted or tramp with one's feet with hand during roll change and fallen hook and had a strong impact on roll change and production time.
The utility model content
Technical problem to be solved in the utility model provides and a kind ofly can guarantee accurately and fast roll change buggy hook position detecting device of roll change buggy hook hook and decoupling device position.
For solving the problems of the technologies described above, the utility model provides a kind of roll change buggy hook position detecting device, comprise metallic plate, hook swing arm, the first approach switch and the second approach switch, described metallic plate is vertically mounted on edge under the roll change buggy platform, described hook swing arm is parallel with described metallic plate, and described the first approach switch and the second approach switch are installed on the described metallic plate.
Further, the spacing of described metallic plate and roll change buggy platform forward edge is 33mm.
Further, the long 265mm of described metallic plate, wide 225mm, the middle part is provided with the rectangle perforate of long 160mm, wide 36mm, and described the first approach switch and described the second approach switch are installed in the described perforate side by side.
Further, between described the first approach switch and described the second approach switch spacing is arranged.
Preferably, the spacing of described the first approach switch and described the second approach switch is 86mm.
Further, it is parallel with described metallic plate and apart from metallic plate 45mm that slotted eye on the roll change buggy platform is passed in described hook swing arm.
Further, described hook swing arm upper end is connected with the electric cylinder piston rod, the lower end is connected with the hook rotating shaft, and described hook rotating shaft is fixed on the roll change buggy lower bearing, is fixed with hook in the described hook rotating shaft.
A kind of roll change buggy hook position detecting device that the utility model provides can guarantee that the positional accuracy of roll change buggy hook elevating control and roll change buggy hook move automatically, have shortened roll changing time.
Description of drawings
A kind of roll change buggy hook position detecting device schematic diagram that Fig. 1 provides for the utility model embodiment.
The specific embodiment
Referring to Fig. 1, a kind of roll change buggy hook position detecting device that the utility model embodiment provides, comprise metallic plate 1, hook swing arm 2, the first approach switch 3 and the second approach switch 4, metallic plate 1 is vertically mounted on 8 times edges of roll change buggy platform, hook swing arm 2 is parallel with metallic plate 1, and the first approach switch 3 and the second approach switch 4 are installed on the metallic plate 1.
Wherein, metallic plate 1 is 33mm with the spacing of roll change buggy platform 8 forward edge.
Wherein, metallic plate 1 long 265mm, wide 225mm, rectangle perforate 7, the first approach switchs 3 and the second approach switch 4 that the middle part is provided with long 160mm, wide 36mm are installed in the perforate 7 side by side.
Wherein, between the first approach switch 3 and the second approach switch 4 spacing is arranged, the spacing of the best between the two is 86mm.
Wherein, it is parallel and apart from metallic plate 45mm that slotted eye and metallic plate 1 on the roll change buggy platform 8 passed in hook swing arm 2.
Wherein, hook swing arm 2 upper ends are connected with electric cylinder piston rod 9, the lower end is connected with hook rotating shaft 5, and hook rotating shaft 5 is fixed on the roll change buggy lower bearing, is fixed with hook 6 in the hook rotating shaft 5.
The operation principle of a kind of roll change buggy hook position detecting device that the utility model embodiment provides is: when electric cylinder piston rod 9 travels forward, the hook swing arm 2 that links to each other with electric cylinder piston rod 9 travels forward, hook swing arm 2 drives the hook rotating shaft 5 that is fixed on the roll change buggy lower bearing and rotates counterclockwise, hook rotating shaft 5 drives hook 6 and descends, when hook swing arm 2 advances to the first approach switch 3 position, hook 6 inserts tram (linking up with successfully) in the working roll bearing block hook groove, the first approach switch 3 signals feed back to PLC by the switching value tablet, the PLC control program makes electric cylinder stop action, hook 6 stop motions; When electric cylinder piston rod 9 during to after-contraction, the hook swing arm 2 that links to each other with electric cylinder piston rod 9 is moved backward, hook swing arm 2 drives the hook rotating shaft 5 that is fixed on the roll change buggy lower bearing and clockwise rotates, hook rotating shaft 5 drives hook 6 and rises, when hook swing arm 2 retreated into the second approach switch 4 position, hook 6 broke away from the hook groove (decoupling device success) of working roll bearing block.After roll change buggy arrival hook position stops, the current hook 6 of the second approach switch 4 feedback is in decoupling device (be hook 6 be in lift) position, control program is just carried out hook control, when control hook 6 descends, the current hook of the first approach switch 3 feedbacks is when the hook position, and control hook 6 stops action.After roll change buggy arrival decoupling device position stops, the current hook 6 of the first approach switch 3 feedbacks is in hook (being that hook 6 is in decline) position, control program is just carried out decoupling device control, when control hook 6 rises, the current hook of the second approach switch 4 feedbacks is when the decoupling device position, and control hook 6 stops action.
A kind of roll change buggy hook position detecting device that the utility model provides is installed in Working roll changing buggy platform bottom, avoided in the former detection architecture, the electric cylinder active force severs test rod greatly, can't detect the physical location of hook, cause hook to move, automatically the defective of roll change has been guaranteed stability and the accuracy of roll change hook position probing to have improved roll change hook hook and the automatic operational efficiency of decoupling device.
It should be noted last that, the above specific embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to example the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
