Description
The utility model relates to a kind of valve, particularly a kind ofly is installed in place, the tapping mouth of a river below the steel ladle, is used for opening, closing and the steel ladle sliding shutter of regulated at will molten steel flow as required by hydraulic-driven.
Gas spring in the existing steel ladle valve all is mounted on the movable underframe, and tapping hole is near from the hyperthermia radiation source, and refrigerating gas enters difficulty, and service life is short.
The patent No. 95232646.9 " metal casting ladle slide-valve " also provides a kind of oil pressure actuated slide plate open and close sliding water valve that utilizes, but adopts artificial locking, and coupling mechanism force is inhomogeneous, the operation effort.
The purpose of this utility model is to provide a kind of rapid operation, convenience, high-temperature stability good, bleed-out, safety, reliable, and maintenance, transposing consumable accessory are convenient, the steel ladle sliding shutter of long service life.
The utility model is achieved in that the steel ladle sliding shutter is by having filling pipe end, the ladle core and the upper frame of upper slide are fixed on the base plate, the following mouth of a river that has hold down gag, lower skateboard is connected with planker, be installed in the underframe, planker is connected with oil cylinder, the spring(-supported) mount that has a gas spring be connected with locking device form, and hold down gag is to have on the inner hole wall on the outer rotation set of skewed slot and the outer wall to have the inward turning cover of projection to connect into one, locking device is by hammerlock and band fulcrum, the pull bar of hook and the spring(-supported) mount that has a gas spring connect, and with upper frame flexibly connect form.
Fig. 1. structural representation of the present utility model.
Fig. 2. the working state figure of Fig. 1.
Fig. 3. the A-A view of Fig. 1.
Fig. 4. the working state figure of Fig. 3.
Fig. 5. the locking device structure schematic diagram.
Below in conjunction with accompanying drawing embodiment of the present utility model is further described:
Hammerlock (4) is a strip, and respectively there is a through hole on centre and top, and there is a clip lower end.
Spring(-supported) mount (3) is a strip, the stairstepping through hole that has uniform 6～10 (determining) to cooperate on it with gas spring (10) according to amount of capacity, and respectively there is the joint pin of a cylindricality at two ends.
Hook (11) has the plate-like of mounting hole on being.
2 fulcrums (6) are weldingly fixed on the pull bar (9), and pivoted arm (7) is fixed on underframe (8) edges at two ends with bearing pin (5) activity for the semicircular arc climbing.
The skewed slot that 3 five equilibriums are arranged on outer rotation set (19) inner hole wall has 3 travellers that protrude on the periphery wall of interior rotation set (20), outer rotation set (19) connects into holistic hold down gag with interior rotation set (20) with skewed slot on it and traveller.
One end of planker (18) is connected with oil cylinder (14) one end links.
One side of upper frame (13) is connected with the bearing of oil cylinder (14), and side is fixed on the base plate (2) with 4 screws in addition.
Locking device is connected on the both sides of upper frame (13) with removable pin by the upper end through hole respectively by 4 hammerlocks (4), the two ends that will have 2 spring(-supported) mounts (3) of gas spring (10) again are separately fixed in the middle through hole of 4 hammerlocks (4), and 2 hooks (11) also flexibly connect with rotational pin with 2 pull bars (9) and are integral.2 pull bars (9) pass the one that clip on 4 hammerlocks (4) connects into shape and form.
The connecting rod of oil cylinder (14) end embeds respectively in the waist v notch v of both sides hooks (11) by the two ends of dwang on it (12), the end of connecting rod is connected with planker (18) in the underframe (8), and be with outward by outer rotation set (19), the hold down gag that interior rotation set (20) constitutes and the following mouth of a river (21), lower skateboard (17) links into an integrated entity, be placed in the die cavity of planker (18), have filling pipe end (15), the ladle core (1) of upper slide (16) is fixed on the middle base plate (2) of upper frame (13), ladle shell (figure does not draw) is welded on the base plate (2), on, underframe (13), (8) link into an integrated entity with bearing pin (22), sliding shutter is assembled into.
During use, oil cylinder (14) moves right by hook (11) pulling pull bar (9), drives planker (18) simultaneously and moves, and makes upper and lower slide plate (16), (17) displacement, and the tapping hole alignment realizes opening.Fulcrum on it (6) position shown in Figure 2 that also moves right, and make pivoted arm (7) on the underframe (8) fulcrum (6) that links closely, make hammerlock (4) downward by pull bar (9), make connected spring(-supported) mount (3) to moving down simultaneously, make gas spring (10) be in compression position, thereby upper and lower slide plate (16), (17) are closely sticked together, and the hydraulic pressure auto lock guarantees that faying face is non-leakage.Hook (11) clockwise direction rotates 90 ° (shown in Fig. 2 double dot dash lines) and contacts with bearing on the underframe (8) simultaneously, prevents pull bar (9) return, the assurance safe locking.
If will keep in repair or change quick-wear part, available hand is opened hammerlock (4) breaks away from and the contacting of pivoted arm (7) clip on it, make hammerlock (4) turn to the splayed configuration position of Fig. 4 from Fig. 3 upright position, coupled spring(-supported) mount (3) also moves to marginal position with it simultaneously, can easily gas spring (10) be taken out transposing and install from spring(-supported) mount (3).If again bearing pin (22) is on one side extracted, make underframe (7) clockwise direction rotating opening, with regard to the upper and lower mouth of a river of interchangeable (15), (21), upper and lower slide plate (16), (17).
The utility model compared with prior art connects with hammerlock because gas spring is installed on the motionless upper frame In the spring(-supported) mount that connects, make it away from the molten steel mouth, and the cooling of available refrigerating gas, service life prolonged. Take Fall bearing pin and open upper and lower framework and hammerlock, can keep in repair simultaneously and change easily part. Hook on the pull bar It is that the stretchy pull bar plays again the position limitation protection effect that double action is arranged. The lower mouth of a river, the outer hold down gag of lower skateboard are Split type, change monolithic construction in the past and the drawback of slight crack guaranteed steel because heat expansion cold volume effect causes The mouth of a river is bleed-out not. And hydraulic automatic locking device, coupling mechanism force greatly, bleed-out not.
