Side steering roll is oppositely arranged, for clamping dummy bar or slab and being oriented to；It is respectively connected with gear on two levers, is located at two
Gear on a lever is identical and external gear engages.Wherein, when the elongation of the piston rod of hydraulic cylinder 4, lever drives corresponding tooth
Wheel rotation, since the rotational angle of external gear pump pair is identical, opposite in phase, so that two side steering rolls turn to position of center line
It is dynamic, reduce the spacing of two side steering rolls, clamps dummy bar or slab.When the piston rod of hydraulic cylinder 4 is withdrawn, lever drives phase
The gear rotation answered, so that two side steering rolls move backward, opening degree (i.e. spacing) increases at two side steering rolls, so as to
To adapt to the bigger section of width.
The utility model since two side steering rolls remain the opposite direction of motion and identical movement angle so that
The utility model ensure that dummy bar or slab can avoid in operational process always along center line movement from mechanical structure
It shifts, so that slab guiding is more acurrate, conveys more stable.
In one alternate embodiment, it is respectively connected with a gear on two levers, two teeth on two levers
It takes turns the engagement of (gear 1 and gear 2 15) external gear and specification is identical, is i.e. the number of teeth and modulus is all the same, two gear ratios
For 1:1.Due to the characteristic of external gear pump, when one of gear rotates a certain angle along axis under the action of moment of face
When, matched another gear can rotate equal angular along opposite direction.When the piston rod of hydraulic cylinder 4 stretches out or recycles
When, due to the property of external gear pump, shaft 1 is opposite with the direction of rotation of shaft 2 16, angle is equal (because of transmission ratio
For 1).It drives lever 1 to rotate in the opposite direction with lever 23 by gear pair and to rotate angle identical, so that side
Guide roller one and side steering roll two are rotated according to the shaft of respective lever, and the spacing between two side steering rolls is decreased or increased, from
And realize the adjustable function of side guiding spacing.The lateral guide send schematic diagram such as Fig. 3 and Fig. 4 institute of different in width slab
Show, wherein it is the structure of the continuous casting billet of W1 that Fig. 3, which shows the lateral guide for sending width,；Fig. 4 shows lateral guide
It is the structure of the continuous casting billet of W2, W1 > W2 for sending width.
In one alternate embodiment, shaft is connected in the middle part of lever, gear is connected to corresponding lever by shaft
On, and connected by flat key between lever and shaft, between gear and shaft, wherein shaft 1 and shaft 2 16 can only
Axis around itself rotates.Lever 1 and lever 23 can be two triangular structures being oppositely arranged, at symmetry axis also
Support arm can be set, the vertex in support arm end can be set in gear, can be integrated molding with the structure of upper lever
It forms.As shown in Fig. 2, lateral guide further includes fixed frame 1, connected between fixed frame 1 and shaft by axle sleeve, guarantees gear
It can be rotated along axis.
In one alternate embodiment, the lower end of two levers passes through the second pin shaft 8 respectively and is connected to the two of hydraulic cylinder 4
End.In order to guarantee that side steering roll maximum, minimal openings degree adapt to different width sections, the piston rod according to hydraulic cylinder 4 is complete
The spacing of corresponding two side steering rolls is maximum opening degree when full withdrawal, and the piston rod of hydraulic cylinder 4 is corresponding when fully extended
Spacing is minimal openings degree between two guide rollers.
In one alternate embodiment, two side steering rolls pass through the upper end that the first pin shaft 7 is connected to two levers respectively.
Since side steering roll is rotated according to the rotary shaft of respective lever, do not ensure that its side is in lead as shown in Figure 1 always
Vertical line direction, therefore the utility model uses the first pin shaft 7 in the connection type of lever and side steering roll and connects, so that the two
Between can relatively rotate.Meanwhile as shown in fig. 6, be provided with 5 between lever and the faying face of corresponding side steering roll~
The gap (being arranged according to minimum and maximum opening degree) of 10mm, makes side steering roll that can only rotate smaller angle around the first pin shaft 7
Degree, ensure that side steering roll is in plumb line state always, thus allow side steering roll that can tightly be attached to dummy bar or casting billet surface,
The rotational angle comparison of side steering roll is as shown in Figure 3 and Figure 4 in device.
Lateral guide can be axially symmetric structure in the present embodiment, be illustrated by taking left side as an example below, such as Fig. 5 institute
Show, lever 1 is connect by the second flat key 14 with shaft 1, and shaft 1 is fixed by the first axle sleeve 9 and the second axle sleeve 13
On fixed frame 1, gear 1 by 11 sets of the first flat key in shaft 1, the upper end of lever 1 by the first pin shaft 7 with
Side steering roll one connects, and lower end is connect by the second pin shaft 8 with hydraulic cylinder 4.Wherein, side steering roll one include by universal shaft with
The side directive wheel 1 that lever one connects, side steering roll two includes the side directive wheel 26 being connect by universal shaft with lever two.
In one alternate embodiment, due in process of production, which is constantly in high temperature, moist outer
Portion's environment is additionally provided with cooling component (not shown) to enable hydraulic cylinder 4 to run normally, for a long time, and cooling component passes through
The cylinder body of hydraulic cylinder 4 is cooled down from the mode of outside water spray.
In one alternate embodiment, in process of production, in order to guarantee two side steering rolls can always tightly close to
The side surface of dummy bar or slab, it is desirable that the output pressure that hydraulic drive mechanism is kept constant makes the piston rod one of hydraulic cylinder 4
Directly it is in stretching state.Pressure controling mode is used in hydraulic drive mechanism, when two side steering rolls clamp dummy bar or casting
When base, hydraulic drive mechanism gives an initial pressure value, correspondingly, so that two side steering rolls and dummy bar or slab one
It directly is kept in contact state, and the lateral pressure that dummy bar or slab two sides are subject to is equal, are as follows: FPressure=FLiquid*LLiquid/LPressure/ 2,
Wherein, FPressureFor dummy bar or slab side pressure, FLiquidFor the power output of hydraulic cylinder, LLiquidFor hydraulic cylinder power output relative to turn
The arm of force of dynamic center (center of rotation of gear), LPressureIt is dummy bar or slab lateral forces central point relative to center of rotation (tooth
The center of rotation of wheel) the arm of force.Wherein, in order not to form biggish resistance of billet withdrawal, hydraulic drive mechanism can select pressure regulator valve,
It is adjustable to be set as 1~5Mpa in conjunction with practical experience branch pressure.
At the intermediate position of lateral guide using a pair of identical external gear pump in the utility model, so that side
Guide roller is synchronous always and counter motion, is overlapped line of symmetry always with casting flow center line, realize opening degree it is adjustable, it is stringent certainly
Dynamic centering does not deviate；The control of hydraulic drive mechanism constant pressure, remains side steering roll with slab and contacts, and lateral pressure is kept
It is constant, it ensure that slab does not shift in the process of running.
The preferred case of the utility model is described in conjunction with attached drawing above, it is clear that the utility model implements not by upper
The limitation of specific embodiment is stated, the above mentioned embodiment is only schematical, as long as using the utility model
The improvement for the various unsubstantialities that method concept and technical solution carry out, or not improved design and technology by the utility model
Scheme directly applies to other occasions, both is within the protection scope of the present invention.
