As shown in Figure 1-2, the utility model discloses a kind of continuous casting steel billet rollgang adjustable end stop, comprise base, be fixedly mounted on the baffle plate bearing 4 on base, the baffle plate 3 hinged with baffle plate bearing 4, be inclined at the hydraulic cylinder bearing 5 of base side, the hydraulic cylinder 6 hinged with hydraulic cylinder bearing 5 and the buffer unit be arranged on baffle plate 3, hinged in the middle part of the piston rod upper end of described hydraulic cylinder 6 and baffle plate 3, described buffer unit comprises bumper bracket 1, fairlead and helical spring, described fairlead is fixedly mounted on baffle plate 3 lateral surface, bumper bracket 1 is tubular structure, and be sleeved on outside fairlead, bumper bracket 1 and fairlead are slidably matched, helical spring 2 is installed inside fairlead, helical spring 2 upper end contacts with bumper bracket 1 inside top, guide post is provided with inside described bumper bracket 1, guide post is arranged through the through hole on baffle plate 3, and at its end mounting limit nut, the hydraulic fluid port of described hydraulic cylinder 6 is connected with hydraulic control system, described hydraulic control system comprises the optoelectronic switch 7, control module and the hydraulic system that are arranged on baffle plate bearing 4 front end, described optoelectronic switch 7 signal output part is connected with control module signal output part, and the signal output part of control module is connected with HYDRAULIC CONTROL SYSTEM end.
Further, hydraulic system described in the utility model comprises oil inlet pipe, drain mast, oil return pipe, three position four-way directional control valve 13, bi-bit bi-pass reversal valve 10, hydraulic control one-way valve 12, check valve 8, choke valve 9 and unidirectional shutoff valve, two hydraulic fluid ports of described three position four-way directional control valve 13 connect oil inlet pipe and oil return pipe, two other hydraulic fluid port of three-position four-way valve connects the identical branch road of two-strip structure respectively, article two, branch road is respectively left branch and right branch, left branch comprises the left side hydraulic control one-way valve 14 and left side one-way throttle valve 15 that connect successively, right branch comprises the right side hydraulic control one-way valve 12 and right one-way choke valve 11 that connect successively, the rod chamber of the outlet connecting fluid cylinder pressure 6 of described left side one-way throttle valve 15, the rodless cavity of the outlet connecting fluid cylinder pressure 6 of right one-way choke valve 11, the end of left branch be connected a set of check valve 8 between drain mast, the bi-bit bi-pass reversal valve 10 and choke valve 9 of connecting are set between right branch with oil return pipe, a hydraulic fluid port of bi-bit bi-pass reversal valve 10 is connected with oil return pipe, a hydraulic fluid port of choke valve 9 is connected to right one-way choke valve 11 port of export of right branch by pipeline, the signal output part of described control module connects bi-bit bi-pass reversal valve 10 respectively, the control end of right side hydraulic control one-way valve 12 and three position four-way directional control valve 13.
In embody rule process, adjustable end stop under normal circumstances, be in gear billet state, namely baffle plate is in raised configuration, now, 1DT and 2DT of three position four-way directional control valve holds dead electricity, three position four-way directional control valve 13 is in meta unloading condition, hydraulic system for lifting keeps left side hydraulic control one-way valve 14, the self-locking of right side hydraulic pressure control check valve 12, because bi-bit bi-pass reversal valve 10 does not receive the signal that control module transmits in buffer loop, the 3DT of bi-bit bi-pass reversal valve must not hold electricity, and bi-bit bi-pass reversal valve is in off state.
When continuous casting billet sends from roller-way, when detecting continuous casting steel billet by optoelectronic switch 7, the 3DT of bi-bit bi-pass reversal valve holds electric, by check valve 8, choke valve 9, the buffer hydraulic system that bi-bit bi-pass reversal valve 10 forms overlaps successfully, when steel billet knocks bumper bracket 1, baffle plate 3 rotates around baffle plate bearing 4 and makes vestibule and piston rod retrude on the piston rod that tangles with it, now hydraulic cylinder 6 rod chamber passes through check valve 8 from hydraulic system drain mast L oil suction, the hydraulic oil of hydraulic cylinder 6 rodless cavity is by choke valve 9, bi-bit bi-pass reversal valve 10 draining, regulate the size of the valve port of choke valve 9, namely adjustable moment draining speed, namely regulate the size of buffering.After buffering N second (buffer time can be fixed by field condition, be generally 2 ~ 4 seconds), the 3DT of bi-bit bi-pass reversal valve holds dead electricity, and buffer loop is cut off, and buffering work completes.The 2DT of three position four-way directional control valve holds electric, pressure oil promotes piston by the rodless cavity that three position four-way directional control valve 13, right side hydraulic pressure control check valve 12, right one-way choke valve 11 enter hydraulic cylinder 6 and upwards walks, the hydraulic oil of the rod chamber of hydraulic cylinder 6 is got back in the oil return pipe of hydraulic system by left side one-way throttle valve 15, left side hydraulic control one-way valve 14, three position four-way directional control valve 13 simultaneously, when piston rises to the top of hydraulic cylinder, adjustable end stop reset work completes.
When control module receives the signal allowing continuous casting steel billet pass through, the 1DT of three position four-way directional control valve holds electric, pressure oil enters into the rod chamber of hydraulic cylinder 6 by three position four-way directional control valve 13, left side hydraulic control one-way valve 14, left side one-way throttle valve 15, piston is declined, simultaneously hydraulic cylinder 6 flow back in the return line of hydraulic system without the hydraulic oil in the bar of chamber by right one-way choke valve 11, right side hydraulic control one-way valve 12, three position four-way directional control valve 13, piston drops to cylinder bottom, baffle plate has declined, and continuous casting billet passes through.
When control module receives gear base signal, the 2DT of three position four-way directional control valve holds electric, pressure oil by three position four-way directional control valve 13, right side hydraulic pressure control check valve 12, right one-way choke valve 11, enter into the rodless cavity of hydraulic cylinder 6, piston is made to increase, the hydraulic oil in the bar of chamber that has of hydraulic cylinder 6 flow back in the return line of hydraulic system by left side one-way throttle valve 15, left side hydraulic control one-way valve 14, three position four-way directional control valve 13 simultaneously, piston rises to hydraulic cylinder top, adjustable end stop has risen, continuous casting billet not by.1DT, 2DT of three position four-way directional control valve hold dead electricity, and hydraulic system keeps left side hydraulic control one-way valve 14, the self-locking of right side hydraulic pressure control check valve 12, and now adjustable end stop gear base rising work completes.
In a word, the utility model by installing buffer unit on baffle plate, when continuous casting steel billet is close to baffle plate, buffer unit rollback certain distance, prevent continuous casting steel billet from impacting baffle plate and hydraulic cylinder, increase the service life, in addition on the one hand, by the action adopting the hydraulic system with pooling feature to carry out hydraulic control cylinder, in adjustable end stop process, realize steadily buffering, the kinetic energy of continuous casting billet can be absorbed, reduce shock loading, good buffering effect can be obtained while realizing baffle plate lifting, there is reliability high, the advantage of compact conformation; The utility model makes baffle plate reset by hydraulic system for lifting, and uses optoelectronic switch to detect the position of steel billet, and by control module hydraulic control system, baffle plate positioning precision is high, reliable, manufactures simply, installs and keep in repair all very convenient.
