Description

The invention relates to the field of metallurgy, in particular to blast furnace production, and in particular to equipment of a foundry for covers of casting gutters, and can be used in the design, construction and reconstruction of blast furnaces.

A well-known foundry of a blast furnace, on which between two adjacent casting troughs extending in the radial direction from the blast furnace, a manipulator is installed for the covers of the gutters. The bearing base of the manipulator with a rotary mechanism with an arrow is installed on the floor of the foundry yard of the blast furnace on the bisector line of the angle formed by the longitudinal axes of the two casting grooves (RF patent No. 2398168, IPC F27D 3/14, 08.16.2006).

The free space of the foundry between two adjacent and closely spill casting troughs, in which additional equipment can be placed, is very limited. The known device is structurally placed on the floor of the foundry and in a limited space between closely spaced gutters, its use creates difficulties in servicing other equipment of the foundry.

Known mounted on the foundry yard of a blast furnace, a manipulator (RF patent No. 2260057, IPC C21B 7/14, 01/15/2004, prototype) for caps of casting troughs, including a support located between two casting troughs, on which a rotary mechanism is mounted, an arrow mounted on the rotary mechanism and associated with the hydraulic cylinder moving its end section in a vertical plane, hooks mounted on the end section of the boom on the horizontal axis and associated with the hydraulic cylinder of their rotation and capture of eyes on the lid of the casting eloba.

Such a manipulator is also structurally mounted on the floor of the foundry, which is problematic when it is installed between adjacent closely spaced pouring channels, has relatively limited maneuverability when installing and moving the cover of the channel.

The basis of the invention is the task to equip the foundry with a manipulator for the lids of the troughs, which, due to the new design, would have a compact small-sized design and placed in a cramped space between two closely spaced adjacent gutters, had high maneuverability when installing and orienting the lids of the troughs

The problem is solved in that in the manipulator for the covers of the casting gutters, including a support located on the side of the casting gutter, on which the rotation mechanism is mounted, an arrow mounted on the rotary mechanism and connected to the hydraulic cylinder for moving its end section in a vertical plane, hooks mounted on the outer end section of the boom on the horizontal axis and associated with the hydraulic cylinder of their rotation to capture the eyes on the lid of the casting trough, according to the invention, the rotation mechanism is made in the form of a forked console mounted in a vertical plane, which is connected with the support by a bracket, a substantially vertical axis, and a two-shouldered lever fixed between the console forks, one shoulder of which is pivotally connected by an earring to the bracket, and the second with a hydraulic cylinder rod mounted on the fork console, and the two-arm lever and the axis of the hydraulic cylinder are placed in the same horizontal plane perpendicular to the vertical axis of attachment of the fork console to ensure rotation of the console relative about the specified axis.

Preferably, the rotation mechanism with the boom were placed directly on the column of the blast furnace.

It is also possible for the pivoting mechanism to be located on a support on the floor of the foundry, essentially on the bisector line of the angle formed by two casting troughs at a distance from the outer casing of the blast furnace that does not exceed the operating range of the manipulator.

In addition, the hooks are freely suspended on a horizontal axis fixed to the boom, and their upper section is connected with the hydraulic cylinder for their rotation.

The execution of the console in the form of a fork and its location in a vertical plane made it possible to constructively place the rotation mechanism between the forks of the console. This solution made it possible to compactly place the two-arm lever and the hydraulic cylinder for turning it inside the console fork, thereby the entire structure occupies a small area in the foundry, has high maneuverability when installing and orienting the covers of the casting troughs.

The manipulator is presented in the drawings:

The manipulator for the covers of the pouring gutters contains a support 1, on which the rotation mechanism is fixed by means of a bracket 2 in the form of a fork console 3Y mounted in the vertical plane and a two-arm lever 5. mounted between the console forks, the fork console is mounted on the bracket on the vertical axles 6. One shoulder 7 of the two shoulders of the lever 5 is pivotally connected to the earring 8, which is mounted on the bracket 2, and the second shoulder 9 is connected to the rod of the hydraulic cylinder 10 located on the console 3, to ensure the rotation of the lever 5 and, respectively about the rotation of the console 3 about the axis 6. On the console 3 on the axis 11 there is an arrow 12. On the free end section of the boom 13 on the horizontal axis 14, the hook 15 is freely suspended. The upper portion of the hook is connected to the hydraulic cylinder 16, the housing of which is fixed on the arrow 12. When moving The rod of the hydraulic cylinder 16, the hook has the ability to rotate around the axis 14 of its suspension and capture or release the eyelet mounted on the cover of the casting trough.

A hydraulic cylinder 17 is fixed to the console 3, connected with the boom 12 to move the end section 13 of the boom with the hook 15 in a vertical plane. On the bracket 2, on both sides of the fork console 3, brake stops 18 and 19 are fixed to fix the position of the console with the boom in working positions at one and the other of the casting grooves, the exact orientation of the boom and hooks getting into the eyes on the lid of the casting groove.

From the garage position A (Fig. 3), in which the console with the boom is located between two casting grooves practically on the bisector of the angle between the axes of the grooves and is directed away from the furnace (as shown in Fig. 3), the manipulator should be moved to the working position B or C to one of the troughs. In the garage position of the manipulator, the rod of the hydraulic cylinder 10 of rotation of the console is half extended. When the swing cylinder rod is fully extended, the two-arm lever rotates the console with the boom to the working position B to the right to the casting chute until the console is locked with the brake stops 19. When the rotary cylinder rod is retracted, the two-arm lever rotates the console with the boom to the operating position C. When moving, the console with the boom will cross the garage the position and the boom will be locked in the working position at the casting trough. The movement of the console in this case will be limited by the brake stops 18.

In the working position B of the manipulator at the casting trough, the boom of the manipulator is precisely fixed by the stop 19 above the cover of the trough for subsequent capture of the eyes on the cover of the casting trough. To ensure that the hooks capture the eyes of the lid of the casting trough, the boom section 13 is lowered down using the hydraulic cylinder 17 and, by adjusting the rotation of the hooks by the hydraulic cylinder 16, the lugs of the lid of the casting trough are captured. Then the gutter cover is transported to the garage position A (Fig. 3) of the manipulator. After closing the notches of the furnace, the lid is returned to the filling trough from the garage position.

Similarly, the manipulator, after turning the boom to the casting chute to the operating position C, performs operations with the cover of this chute.

Such a simple and reliable design of the manipulator for the covers of the casting gutters will allow it to be operated in any foundry. This is especially necessary for small foundries with closely spaced troughs, where the use of a manipulator will free up the foundry yard for other maintenance work. The design of the manipulator will allow you to replace the expensive slewing ring with relatively inexpensive bearings of small diameter and simplify the design of the manipulator.
