The specific embodiment
For the mode carrying out an invention
Below, by embodiment, embodiments of the present invention are described.
[embodiment]
Fig. 1 rises under the state of extreme higher position at piston rod 2, by the rotating shaft of the central shaft that comprises piston rod 2 and top roll 6, in interior plane, cut the front view on top of the light screwdown gear of embodiment, Fig. 2 drops under the state of extreme lower position at piston rod 2, has been cut the front view on top of the light screwdown gear of embodiment by the rotating shaft of the central shaft that comprises piston rod 2 and top roll 6 in interior plane.
In addition, for the identical structural element of the light screwdown gear with in the past, added the numbering identical with Fig. 6.
Hydraulic cylinder 1 in embodiment, piston rod 2, framework 3, lifting frame 4, two top bearing housings 5, top roll 6, two lower bearing housings 7 and lower rolls 8, with the light screwdown gear in the past shown in Fig. 6 be same.
And, in an embodiment, in order to prevent the hydraulic cylinder 1 of light screwdown gear and piston rod 2 to be exposed on the radiant heat that produces from the slab of high temperature and hot gas, become high temperature, surrounding at piston rod 2 is provided with undulatory cover 9, and be provided with hot gas guard shield 10, this hot gas guard shield 10 is connected the peristome 11 of the bottom of piston rod 2 and framework 3, has the undulatory hot shielding film 13 correspondingly stretching with the lifting of piston rod 2.
In addition, for anti-stopping bar front end metal-ware 21 is by radiant heat, hot gas and from the heat conduction heating of lifting frame 4 and become high temperature, in the surrounding of bar front end metal-ware 21, forced cooling device 20 has been installed.
In order to connect the bottom of piston rod 2 and the peristome 11 of framework 3 by hot gas guard shield 10, as shown in Figures 1 and 2, by by be arranged on the fastening accessory 12 of an end of hot gas guard shield 10 and the surrounding of the bottom of piston rod 2 chimeric fastening, one end of hot gas guard shield 10 is fixed on to the bottom of piston rod 2, in addition, as shown in Figures 3 and 4, by the standing finish 14 of four コ word shapes that is arranged on the other end of hot gas guard shield 10 being inserted to the edge of peristomes 11, and come off and prevent that excellent 15 press the standing finish 14 of two コ word shapes in opposite directions near its both ends to framework 3 thrusters by two standing finishes, the other end of hot gas guard shield 10 is fixed on framework 3.
Therefore, can an end and the other end of hot gas guard shield 10 easily and be reliably installed respectively to the bottom of the piston rod 2 of mounted light screwdown gear and peristome 11, in addition, when newly light screwdown gear being set, not need to carry out design alteration.
Fastening accessory 12 forms in such a way,, has the structure same with flexible pipe being fixed on to accessory on tap that is, by make operating portion by the instruments such as pliers or screwdriver or hand to a direction rotation, girth extends, by rotating to other direction, girth shortens.
In addition, standing finish comes off and prevents that rod 15 forms in such a way,, by central axial region is extended to a direction rotation, by shortening to other direction rotation, by being arranged near the both ends of standing finish 14 of コ word shape, can be limited by central axial region the standing finish 14 of other two コ word shapes in opposite directions, it is not come off.
With the lifting of piston rod 2 flexible undulatory hot shielding film 13 correspondingly, by the straight line of the length of the same length at the edge with peristome 11 or circular-arc base, at piston rod 2, drop under the state of extreme lower position and bight from peristome 11 hypotenuse to the length of the same length of the bottom of immediate piston rod 2, form with the straight line of the length of the same length of the periphery of bottom with piston rod 2 or circular-arc top, , in the hypotenuse portion of the heat-resisting fabric of isosceles trapezoid roughly, heat-resisting fastener has been installed, and then, by the metal elastomer processed that becomes at leisure large ring-type from upper avris (end side) to base side (the other end side), under the state of having closed heat-resisting fastener, to become respectively, the mode of approximate horizontal installs.
In addition, heat-resisting fabric is the cloth by the braiding of the heat resistant fibre such as glass fibre, be with needs correspondingly to folk prescription or both sides' surperficial evaporation the cloth of aluminium oxide, silicon etc.
Be arranged on the forced cooling device 20 of the surrounding of bar front end metal-ware 21, by the heat shield 22 forming with heat-resisting fabric, water-cooled cooling end 23, the flow pipe 24 that water is sent into cooling end 23 of inner side that are arranged on heat shield 22 and the drainpipe 25 of water being sent from cooling end 23, formed, by cooling end 23, force cooling rod front end metal-ware 21, and cut off from outside radiant heat, hot gas by heat shield 22.
