Problem described in the utility model realizes with following technical proposals:
A kind of continuous casting billet adjustable end stop, formation comprises crossbeam, balladeur train, slide plate, lifting hydraulic cylinder and two-stage spring bumper, described crossbeam is fixed on the roll surface bottom of rollgang vertical with roller-way, described balladeur train is fixed on meeting on material side of crossbeam, its one side towards continuous casting billet is provided with operating slide guideway rail, described slide plate is positioned at the vertical chute of operating slide guideway rail, the cylinder body of described lifting hydraulic cylinder is articulated with balladeur train bottom, the lower end of its piston rod and slide plate is hinged, and described two-stage spring bumper is fixed on the upper end of slide plate corresponding with continuous casting billet.
Above-mentioned continuous casting billet adjustable end stop, described two-stage spring bumper comprises interior guide cylinder, outer guide cylinder, gland, wind spring, cylindrical spring and leading screw, described outer guide cylinder is fixed on the upper end of slide plate by base, its axis is parallel with roller-way, described cylindrical spring coaxial package with outer guide cylinder in, one end coaxial package of described interior guide cylinder is pressed on cylindrical spring on the inner also top of guide cylinder outside, the other end is fixedly connected with gland, it is inner that described wind spring pine is enclosed within interior guide cylinder, one end of described leading screw is fixed on gland, the other end is successively through screwing in nut after cylindrical spring and base.
Above-mentioned continuous casting billet adjustable end stop, described slide plate is provided with vertical reinforcement towards the one side of continuous casting billet, and the piston rod of lifting hydraulic cylinder and the reinforcement of slide plate are hinged.
Above-mentioned continuous casting billet adjustable end stop, the top of described crossbeam is provided with bearing, and the part that described balladeur train exceeds crossbeam leans against on bearing and with bearing and is fixedly connected with.
Above-mentioned continuous casting billet adjustable end stop, the shared bottom girder of a plurality of adjustable end stops that described crossbeam is conticaster.
The utility model employing two-stage spring cushions, damping, has effectively avoided continuous casting billet to the impact of adjustable end stop and destruction, thereby has greatly improved the reliability of adjustable end stop, has guaranteed the normal operation of continuous casting line.This device adopts the method for the shared crossbeam of multithread, has increased the impact strength of adjustable end stop.The advantages such as in addition, the utility model also has simple in structure, compact, easy to maintenance.

In figure, each list of reference numerals is: 1, crossbeam, 2, adjustable end stop, 3, bearing, 4, lifting hydraulic cylinder, 5, operating slide guideway rail, 6, slide plate, 7, lubricating cup, 8, upper pin, 9, lower bearing pin, 10, gland, 11, wind spring, 12, balladeur train, 13, leading screw, 14, cylindrical spring, 15, base, 16, reinforcement, 17, interior guide cylinder, 18, outer guide cylinder.
The specific embodiment
While adopting the utility model to stop continuous casting billet, each stream of conticaster shares a crossbeam 1 and does bottom girder, the adjustable end stop 2 of each stream is installed on this bottom girder, the balladeur train 12 of each adjustable end stop is fixed on crossbeam 1, bearing 3 is installed on crossbeam 1 in order to support adjustable end stop 2, bearing 3 welds together with crossbeam 1 and balladeur train 12, on the balladeur train 12 of adjustable end stop 2, lifting hydraulic cylinder 4 is installed, slide plate 6 and operating slide guideway rail 5, lifting hydraulic cylinder 4 is hinged by upper pin 8 and slide plate 6, there are two vertical chutes the both sides of operating slide guideway rail 5, vertical chute play the guiding role to slide plate 6, lifting hydraulic cylinder 4 drives slide plate 6 lifting in operating slide guideway rail 5, the function that realization is blocked steel billet and let pass to steel billet.The two-stage spring bumper of adjustable end stop comprises gland 10, wind spring 11, cylindrical spring 14 and leading screw 13.The coefficient of elasticity of wind spring 11 is larger, and the coefficient of elasticity of cylindrical spring 14 is less, uses such two kinds of springs, can make adjustable end stop adapt to the steel billet of friction speed and different quality (different cut lengths).The effect of leading screw 13 is exactly being fitted together by gland 10, wind spring 11, cylindrical spring 14 and base 15.
When need to stop on roller-way steel billet time, lifting hydraulic cylinder 4 drives slide plate 6 to rise along operating slide guideway rail 5, make gland 10 exceed roll surface, now adjustable end stop 2 has been carried out the preparation of gear steel billet, when steel billet touches gland 10, the cylindrical spring 14 in two-stage spring bumper is first compressed, has consumed the kinetic energy of a part of steel billet, remaining energy will disappear in the process of coil compression springs 11, has so just reduced the impact of steel billet to adjustable end stop 2.When needs steel billet passes through, lifting hydraulic cylinder 4 drives slide plate 6 to decline, and the gland 10 of two-stage spring bumper is lower than the roll surface of roller-way, and steel billet will be crossed adjustable end stop 2.
