- the length of the tensioned belt between the pinions 19d, 19e is adapted such that the transport carriage 11 is movable from the front end position to the rear end position along the transport carriage guide 18 of the tilting frame 10.
- the trolley 11 is firmly connected to the second belt 19.
- the coupled to the bar shoe 40 through the hook 22 hook carriage 21 is in the second step by the first belt 29 and the
- Hook drive 29e driven in the direction of the rear end position along the longitudinal guide 23 of the guide frame 20, so that the ingot shoe 40 on the
- the lifter 30 is used to release the hook 22 from the bar shoe 40 as shown in FIG. This is about the
- Lifting drive 31 actuates the kinematic chain formed by the hinge assembly 32, thereby causing the lifter 30 is raised.
- the lifter 30 lifts the roller 22h or the finger 22g and thus the lever arm 22f upward, whereby due to the rotation axis 28, the hook tip 22b is lowered.
- the engagement of the hook 22 in the bar shoe 40 and the lateral projection 41 of the bar shoe 40 is released.
- the lifter 30 remains raised, at the same time the hook carriage 21 is moved further towards the rear end position.
- Through the roller 22h and the Aushebeschiene 33 is thereby achieved that the hook 22 remains in the tilted position, at least until the hook 22 is spaced from the bar shoe 40 or dolly 11.
- the guide frame 20 is arranged in an elevated position. This means that the guide frame 20 is driven by the lifting drive 24 in the upper end position.
- the guide frame 20 is lowered or moved to a lower end position.
- the lifting drive 24 is actuated, whereby the lifting joint 25 rotates about the fourth pivot 25b and causes the lowering of the guide frame 20.
- the fourth step or step of the carriage 1 is operated to the
- the Abkippvoretti 70 is shown in Figures 7 to 13 as a hook-like or shovel-like dump truck.
- the Abkippvortechnischmaschine 70 serves to store the rolling bar 50 on a scroll or a rolling mill feed.
- Transport carriage 11 by the corresponding belt drive, in particular the second belt 19, moved in the direction of the rear end position.
- the transport carriage 11 is positioned substantially centrally with respect to the transport carriage guide 18 in this method step, so that there is sufficient free space laterally around the transport carriage 11 for transferring the rolling bar 50 to the tilting device 70.
- the trolley 11 is thus removed from the oven, so that the oven door can be closed.
- Dumping device 70 engages between the two dolly 11, the are arranged parallel to each other, as shown in FIG. 2 shown. In this
- FIG. 9 The transfer of the rolling bar 50 to the tilting device 70 is shown in FIG. 9 shown.
- the tilting frame 10 is tilted by actuation of the tilting drive 15, wherein the tilting frame 10 rotates about the tilting axis 14.
- actuation of the tilting drive 15 in particular, a rotation of the tilting joint 17 takes place around the first pivot 17 a, as a result of which the tilting of the tilting drive 17
- Tilting frame 10 is effected.
- the tilting movement of the tilting frame 10 of the rolling ingot 50 is deposited on the Abkippvorraum 70, wherein the
- Barren shoes 40 remain on the trolley 11.
- the tilting frame 10 initially remains in the tilted position, wherein the transport carriage 11 is moved back into the front end position or the transfer position.
- the Abkippvorraum 70 is tilted or pivoted to bring the edgewise taken roll bar 50 in a substantially horizontal position or store with a flat side on a scroll or a Walztechnikzuz leadership.
- the carriage 1 is, however, positioned in front of a cash draw return 80, wherein the
- Guide frame 20 is lifted by the lifting drive 24 in the upper end position.
- the trolley 11 is moved forward to the front end position, so that the rail pieces 12 with return rails 81 of the
- Barrenschückückmba unit 80 form a common, elongated guide for the ingot shoes 40.
- the hook carriage 21 is also moved to the front end position, with the hook in the bar shoe 40, which on the
- Dolly 11 is arranged, engages or hooks.
- the hook carriage 22 also grips the hook 22 substantially automatically, by the sliding surface 22c of the hook tip 22b sliding along the projection 41 of the ingot shoe 40 and the tilting movement of the hook 22 triggers.
- the rear stop 22e of the boom 22a, which is part of the hook 22, comes in this process in abutment with the lateral projection 41 of the bar shoe 40, so that in the further ancestor of the hook carriage 21 of the Bar shoe 40 from the rail section 12 of the trolley 11 on the
- the lifter 30 is actuated to release the hook 22 from the ingot shoe 40.
- the operation of the boom 30 is analogous to the method step described above, in which the hook 22 after the
- the hook carriage 21 is moved back, wherein the hook 22 alsgru nd the raised lifter 30 remains in the tilted position until the hook carriage 21 is far enough away from the Barrenschuhschreib Entry 80, the roller 22h and the finger 22g from the Aushebeschiene 33 slides down and thus the automatically resetting the hook 22 in the rest position releases.
- the hook carriage 21 is moved to the rear end position.
- Dolly guide 18 The hook carriage 21 is still in the rear end position. In this configuration, the operation of the trolley 1 between the ovens or between a furnace and the tilting device 70 is permitted.
- the truck 1 is operated to position the transport device in front of a furnace which discharges the next heated and homogenized rolling ingot 50.
- the transport device is brought into the basic position for the next clock sequence.
- the hook carriage 21 is moved to the waiting position.
- the waiting position of the hook carriage 21 is shown in FIG. 14 then reaches when the boom 22a of the hook 22 substantially laterally of the trolley 11 and below the rail section 12th
- the guide frame 20 is preferably arranged in the basic position in the lower end position, ie in the lowered position. As soon as the oven is ready for the next roll bar 50, the oven door is opened and immediately the guide frame 20 is raised to hold the one hand
- the transport device or the barrow thus has the following
- the carriage 1 preferably corresponding means, such as brakes on. Furthermore, it is advantageous if the
- Transport device includes heat or radiation shields, which the
- the heat or blasting shields are preferably arranged in the front region, that is on the furnace side, of the transport device.
- Radiation shields or heat shields can be assigned to the tilting frame, the guide frame and the carriage on the furnace side.
- 19b, 19c, 19d, 19e further sprockets
- first Riemena Antriebritzelb, 29c, 29d further Ritzele hook drive
