Definitions
- the invention relates to a support device for ladles in a Continuous caster, with a fixed base and a relative to this rotatably mounted and by means of a rotary drive rotatable swivel base on which an articulated parallelogram system with pivotable about horizontal axes and arranged one above the other Handlebars at least one support arm system to accommodate a pouring ladle is articulated, the support arm system by means of at least one Pressure cylinder can be raised and lowered relative to the rotating base.
- a device of this type is known from EP-A-0277846.
- the support arm system is of a U-shaped plan, a Forming ladle encompassing frame, at the free ends of which The ladle is supported and on which the legs of the U connecting Cross member, which is designed as a box girder, a pressure medium cylinder attacks, with the help of which the support arm system can be raised and lowered.
- box girder are also the upper links of the Articulated parallelogram system.
- a support device for ladles in a continuous caster with an articulated parallelogram system and a support arm system is also from DE-A-24 30 786 known. Grab this support device Pressure cylinder, each with one end on a rotating column of the Carrying device are supported, with their other ends directly to the
- the invention aims to avoid these disadvantages and Difficulties and the task of a carrying device of the to create the type described above, the handlebars of the Joint parallelogram system only through tensile and compressive forces are claimed, so that these handlebars are particularly light can.
- the handlebars of the Joint parallelogram system only through tensile and compressive forces are claimed, so that these handlebars are particularly light can.
- the parts of the Support device, in particular its pressure cylinder in a simple They are accessible from above and can be repaired quickly and cheaply Can be carried out using the indoor crane.
- this object is achieved by - That the support arm system is formed by two independent support arms, each support arm being articulated to a lower and an upper link of the articulated parallelogram system, - That the upper links of the articulated parallelogram system are combined at their ends facing away from the rotating base by means of a cross bar to form a rigid unit which is U-shaped in plan, and - That the crossbar is supported on the at least one pressure cylinder by means of a swivel joint, the swivel joint being in alignment with the joints of the upper link arranged at the ends facing away from the rotating base.
- a preferred material-saving construction is thereby characterized in that the rotating base of a rotating platform and of this vertically towering stand is formed in the area of the Outer periphery of the rotating platform are arranged, and that the upper and lower links are hinged to the stands.
- the upper and lower links are useful in a vertical position Articulated in the direction of superimposed joints on the uprights.
- a particularly simple design with two diametrically opposed opposing joint parallelogram systems and associated Support arm systems for receiving a ladle each is thereby characterized in that each of the upper and each lower link both articulated parallelogram systems with aligned axes on the Stands are hinged.
- the upper links are preferably L-shaped in a side view, with each upper link from one to the pivot on the swivel base Joint on the support arm extending arm and one of the joint of the Support arm is formed upwardly extending arm of the L, and is the Crossbar at the top of the arm from the joint upwardly extending arm connected to the upper links.
- FIG. 1 being a schematic Side view, partially in section, shows.
- Fig. 2 shows a view in Direction of arrow 11 of Fig. 1 is also partially cut.
- Fig. 3 is a sectional view along the line III-III of FIG. 2.
- the support device 1 has a on a casting platform 2 a Continuous caster stationarily mounted annular fixed base 3 with im Compared to the diameter of the low overall height.
- Rotating base 4 by means of a slewing ring bearing 5 around a vertical axis of rotation 6, which is aligned with the central axis of the fixed base 3, rotatably mounted, wherein the rotary movement by means of rotary drive motors 7, which are attached to a console 8 of the fixed base 3 are mounted, is accomplished.
- the motors 7 drive Pinion 9, which is inserted into a ring gear 10 arranged on the rotating base 4 intervention.
- the rotating base 4 is formed by a rotating platform 11 from the two parallel, each in the area of the outer circumference of the Rotary platform fixed and diametrically opposed to each other vertical uprights 12, 13 rise.
- Each lifting device is from one Articulated parallelogram system 17, which is articulated on the uprights 12, 13, and a support arm system 18 which is attached to the articulated parallelogram system 17 is articulated, and a pressure cylinder 19, such as a Hydraulic cylinder, formed.
- Each joint parallelogram system 17 has two upper links 20, 21 and two lower links 22, 23, each of which has an upper link 20, 21 and one lower link 22, 23 to one of the stands 12, 13 in the vertical direction are pivoted. This creates two parallel, articulated parallelograms 24, 25 extending in the vertical direction educated.
- the upper links 20, 21 of these two articulated parallelograms 24, 25 are through a crossbar 26 to a U- shaped rigid unit 27 combined, creating a synchronous Movement of the two joint parallelograms 24, 25 is secured.
- each stand 12, 13 is of two parallel ones Plates 28 formed, the joints 29 of the joint parallelograms 24, 25 are formed by hinge pins 30 extending from a plate 28 to other stretch.
- the respective upper links 20, 21 and lower Handlebars 22, 23 of the two joint parallelogram systems 17 of the Lifting devices 14, 15 are aligned to save space arranged so that the upper and lower links 20, 21; 22, 23 of the two Joint parallelogram systems 17 on one and the same Hinge pins 30 are mounted.
- each of the two joint parallelograms 24, 25 is from Support arm system 18 formed, which two independent Support arms 31,32, which are L-shaped in side view, has.
- Support arm 31, 32 has a horizontal part 33 and a vertical part 34 on, wherein the vertical part 34 on each a lower link 22,23 and an upper link 20, 21 is articulated and the horizontal part 33 is extends from the vertical part 34 to the outside and at its free end a Recording 35 for the ladle 16 carries.
- the handlebars 20, 21; 22.23 with the uprights 12; 13 connecting joints 29 are just like the the lower link 22, 23 with the joints 36 connecting the support arms 31, 32 designed as spherically movable joints in a limited area.
- the vertical movement of the support arm system 18 is by means of Pressure medium cylinder 19 reached, on the one hand by means of a bearing 37 on the rotary platform 11 and on the other hand by means of a swivel joint 38 is hinged to the crossbar 26 of the articulated parallelogram system 17.
- the connecting the pressure cylinder 19 to the crossbeam 26 Swivel joint 38 is arranged so that its bearing axis 39 with the Axes 40 of the two upper links 20, 21 each with a support arm 31, 32 connecting joints 41 is aligned and the line of action 42 of the pressure cylinder 19 caused by the imaginary force horizontal connecting line of the upper links 20, 21 with the Joints 41 connecting support arms 31, 32 runs. This will make the upper handlebars 20, 21 only subjected to train, so that they weight and can be designed to save costs.
- a second arm 44 of the L extends vertically upward at right angles to the first arm 43 of the L.
- At the upper end of the second arm 44 is horizontal to the opposite upper links 20, 21 extending and parallel to the horizontal axes 40, 45, 46, 47 of the joints 29, 36, 41 of the Joint parallelograms 24, 25 extending crossbeams 26 are welded on.
- Reinforcing ribs 48 serve to stiffen the upper links 20, 21 and the crossbar 26 formed U-shaped structural unit 27.
- this structural unit 27 By designing this structural unit 27 in this way, it is possible in simply the swivel joint 38 with which the pressure medium cylinder 19 is hinged to the crossbar 26, below the crossbar 26 on this to be attached, so that the crossbeam 26 is not through recesses is weakened and an alignment of the pivot joint 38 in every position the handlebars 20, 21, 22, 23 with the joints 41 is ensured.
- the expansion of a pressure medium cylinder 19 is particularly simple, since it is only necessary to use the joint parallelogram system 17 either with the defective pressure cylinder itself or by means of a to raise external lifting means and the pressure cylinder by means of a Crane up through the free space between the cross member 26 and to remove the two links 20, 21 from the support device.
