Abstract
The utility model discloses a disassembling pull rod for a steel ladle upper nozzle, which comprises a handle screw rod, a wedge-shaped head, an expansion pipe, a pressing plate, a locking nut, a cage-shaped mandrel supporter, a shim plate and a nut. The cage-shaped mandrel supporter comprises a circular ring at a left end and a circular plate at a right end; the edges of the circular ring and the circular plate are connected with a plurality of rib plates; the handle screw rod passes through the cage-shaped mandrel supporter; the left end of the handle screw rod is fixedly connected with the wedge-shaped head; the nut is screwed on threads at the right end of the handle screw rod; the shim plate is arranged between the nut and a right end plate of the cage-shaped mandrel supporter; the expansion pipe and the pressing plate are both sleeved on the handle screw rod; and the locking nut is screwed on intermediate threads of the handle screw rod and presses the expansion pipe on the wedge surface of the wedge-shaped head tightly through the pressing plate. When the disassembling pull rod is in use, the expansion pipe is stressed to expand and then is locked and abutted with the hopper surface of an upper nozzle brick, and an upper nozzle necessary to be replaced is pulled out by utilizing the spiral force of the screw rod. By using the disassembling pull rod, the upper nozzle can be taken out in a quite labor-saving way; the labor intensity for replacing the upper nozzle is lightened greatly; the replacing time is saved; and the continuous production is favorable.
Description
Technical field
The utility model relates to the special dismounting pull bar of dismantling ladle upper nozzle.
Background technology
The use of ladle upper nozzle heat surplus ten, because of with upper slide contact the seam misrun, the working face that cooperates with upper slide can not driving fit, so filling pipe end must in time change, otherwise bleed-out danger is just arranged.Basically be at present by using pneumatic pick to smash filling pipe end, clear up residual brick then, installing the new mouth of a river again.But with the operation that pneumatic pick is smashed filling pipe end, not only labour intensity is big, work efficiency is low, and may cause the cracking of pocket block and loosening, ladle nozzle very easily takes place wear the steel accident, produces great safety in production hidden danger.
The utility model content
Problem to be solved in the utility model provides a kind of dismounting pull bar of ladle upper nozzle, quickly and easily filling pipe end is changed.
The utility model ladle upper nozzle dismounting pull bar is characterized in that: it comprises handle screw mandrel, sphenocephaly, expansion tube, pressing plate, locking nut, cage shape saddle support, backing plate, nut; Cage shape saddle support comprises the annulus of left end and the circular slab of right-hand member, and both edges are connected with some gussets; The handle screw mandrel passes from cage shape saddle support, and the fixedly connected sphenocephaly of its left end is rotary with nut on the screw thread of right-hand member, is provided with backing plate between the right end plate of nut and cage shape saddle support; Expansion tube, pressing plate all are enclosed within on the handle screw mandrel, and locking nut is spun on the intermediate thread of handle screw mandrel, and it is pressed on expansion tube on the wedge surface of sphenocephaly by pressing plate.
This dismounting pull bar is sidelong ladle earlier in use, opens ladle nozzle mechanism; To shake hands again sphenocephaly, the expansion tube of screw mandrel left end extend in the upper nozzle brick, follow the rotational lock nut, by pressing plate fitted in the stressed back of expanding of expansion tube with the funnel surface locking of upper nozzle brick, put cage shape saddle support in the other end of handle screw mandrel again, right-hand member at pull bar silk hand screws on backing plate, nut again, the rotation nut is pressed on the right end plate of cage shape saddle support pressing plate cage shape saddle support is pressed on the ladle base, and the filling pipe end that utilizes screw mandrel spiral power will need to change is pulled out.
The utility model has been used for reference the expansion bolt principle, utilizes the spiral force mechanism, can be very effortlessly filling pipe end be taken out, and has alleviated the labour intensity that replaces with the mouth of a river greatly, has saved the replacing time, helps continuous production.Simultaneously, utilize this dismounting pull bar to replace with the mouth of a river, crackle and loosening problem appear in the filling pipe end brick cup of effectively having avoided matching with upper nozzle brick, have guaranteed safety in production.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As can be seen from Figure 1, the utility model ladle upper nozzle dismounting pull bar, it comprises handle screw mandrel 1, sphenocephaly 2, expansion tube 3, pressing plate 4, locking nut 5, cage shape saddle support 6, backing plate 7, nut 8; Cage shape saddle support 6 comprises the annulus of left end and the circular slab of right-hand member, and both edges are connected with some gussets; Handle screw mandrel 1 passes from cage shape saddle support 6, and the fixedly connected sphenocephaly 2 of its left end is rotary with nut 8 on the screw thread of right-hand member, be provided with backing plate 7 between the right end plate of nut 8 and cage shape saddle support 6; Expansion tube 3, pressing plate 4 all are enclosed within on the handle screw mandrel 1, and locking nut 5 is spun on the intermediate thread of handle screw mandrel 1, and it is pressed on expansion tube 3 on the wedge surface of sphenocephaly 2 by pressing plate 4.Wherein, sphenocephaly 2 can be overall structure with handle screw mandrel 1.
This dismounting pull bar is sidelong ladle earlier in use, opens ladle nozzle mechanism; To shake hands again sphenocephaly 2, the expansion tube 3 of screw mandrel 1 left end extend in the upper nozzle brick, follow rotational lock nut 5, by pressing plate 4 fitted in the expansion tube 3 stressed backs of expanding with the funnel surface locking of upper nozzle brick 9, put cage shape saddle support 6 in the other end of handle screw mandrel 1 again, right-hand member at pull bar silk hand 1 screws on backing plate 7, nut 8 again, rotation nut 8 is pressed on the right end plate of cage shape saddle support 6 pressing plate 7 cage shape saddle support 6 is pressed on the ladle base 10, and the filling pipe end that utilizes screw mandrel spiral power will need to change is pulled out.
The utility model has been used for reference the expansion bolt principle, utilizes the spiral force mechanism, can be very effortlessly filling pipe end be taken out, and has alleviated the labour intensity that replaces with the mouth of a river greatly, has saved the replacing time, helps continuous production.Simultaneously, utilize this dismounting pull bar to replace with the mouth of a river, crackle and loosening problem appear in the filling pipe end brick cup of effectively having avoided matching with upper nozzle brick, have guaranteed safety in production.
