Definitions

the invention relates to a device for a quick connection or a quick release of two large, heavy components for the metallurgical plant operation, in particular for a steel continuous casting machine.
Such components are used in steelworks, rolling mill and especially in steel continuous casting. To carry out repairs or maintenance, disassembly takes place at the place of use. The release of piston-cylinder drives, for example.
support roller segments of the continuous casting is time-consuming and material-intensive and is usually in the workshop using additional tools and means of transport.
Such a support roller segment is from the EP 1 232 813 A1 known.
simple nut-nut pairings are used, which are used between a segmental frame and an exchangeable cassette.
the invention has for its object to avoid the difficulties associated with screw connection or disconnection (of stuck elements) and to provide a device for large and heavy components.
a hydraulically controlled clamping unit wherein the clamping force by means of a Hydraulikplungers, which forms a clamping piston with a central disc spring column, can be generated and adjusted, the housing of the clamping unit is connected to the first component and the clamping piston penetrates the first and the second component and carries a detachable with the clamping piston clamping head, which is stretched in the connection state in the opposite direction to the first component against the second component.
a significant advantage of this clamping unit is the fast locking and unlocking of the clamping when connecting or when releasing piston-cylinder actuators, which serve for the employment of a Losrollensegments against a Festrollensegment. In this case, a reduction of the change times of the support roller segments is achieved.
the connection-related design allows the separate removal of roller segments and piston-cylinder drives from a continuous casting apparatus and also provides overload protection of the assemblies in the event of a failure in the casting process.
a time saving when connecting or disconnecting is u.a. achieved in that on the end of the tensioning piston a star head with detent recesses or tooth gaps rotatably disposed and inserted into a ring member of the clamping head, which is arranged axially fixed in the clamping head and secures the clamping position of the clamping head to the second component.
an embodiment is that the ring element of the clamping head slides in a circumferential groove of the star head and by means of an externally arranged pivot unit in the circumferential angle to correspondingly arranged locking recesses or tooth gaps of the star head is rotatable.
a rotation of the ring element by, for example, 30 ° (or a multiple of 30 °) prepares the positive connection of the clutch for transmitting the clamping force.
the swivel unit is easily accessible and can be operated by hand.
the prestressed diaphragm spring column takes over the clamping force of the two components in that the clamping force of the diaphragm spring column can be transmitted via the star head on the ring member and the clamping head to the second component.
An improvement is also that a rotation of the clamping piston in the housing is prevented together with the star head in the clamping head by means of a rotation.
FIG. 1 an application example of the clamping unit 1 is shown, which is located on a straight or curved portion of a strand guide for casting strands of metal, in particular steel.
a support frame 2 accommodates piston-cylinder drives 3 and is connected by means of four clamping units 1 with a fixed side frame 4, on which an adjustable by means of the piston-cylinder actuators 3 Lossllen 5 in a guide.
On the fixed side frame 4 are fixed side rollers 4a and rotatably mounted on the lot side frame 5 Lossrollen 5a and arranged in segmental design.
FIGS. 2 and 2A One of the clamping units 1 is shown in detail in FIGS. 2 and 2A.
a hydraulic plunger 10 is mounted in a housing 9 which is fixed to the support frame 2, wherein the support frame 2 carries the piston-cylinder actuators 3, a hydraulic plunger 10 is mounted.
the hydraulic plunger 10 is equipped with a hydraulic port 11.
the hydraulic plunger 10 forms via an annular collar 11 a, an outlet 11 b and takes on a central journal 12, a plate spring column 13 and a clamping piston 14.
the single-acting hydraulic plunger 10 presses the disc spring column 13 together and clamps them.
the tensioning piston 14 penetrates the support frame 2 and the fixed side frame 4 and is inserted with a star head 15 in a ring member 16 of a clamping head 17, wherein the clamping element 17 surrounding the ring member 16 in tension against the outer Surface of the fixed side frame 4 is pressed.
the tensioning piston 14 extends through a sealed opening 18 of the support frame 2 and further through a passage 19 of the fixed side frame 4.
On the clamping piston 14 is located in the region of the passage 19 at circumferential intervals latched the star head 15.
marks, tooth spaces, locking recesses o.
a shoulder 14a in which a detent pin 21 engages.
the ring member 16 engages over the projections 16a in the distributed over the circumference of the star head 15 star wells 20.
the ring member 16 is cup-shaped and rotatably mounted in a cover 22.
the cover 22 with screws 23 forms a conclusion and at the same time an inner pivot bearing 24, the rotary bearing sleeve 24a is held by means of a pin 21 similar to the pin.
Fig. 2A the locked state is shown.
the pivot bearing 24 stores on the one bearing side, a swivel unit 25 rotatably mounted on both sides. The other bearing side lies outside at a fixed point of the hall scaffold.
the rotation of the ring element 16 in a circumferential groove 15a of the clamping head 17 by, for example, 30 ° or a multiple of 30 ° prepares the positive connection of the coupling for transmitting the axial clamping force.
no electrically or hydraulically controllable drive is provided.
