Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to an operating device for replacing a flow path, particularly a main iron flow path of a blast furnace. [Prior Art] In a casting chamber of a blast furnace, pig iron and pig iron slag are separated in a main flow path, and the main flow path is connected to the first-class outlet of the blast furnace. Such a main flow passage is a groove provided with a refractory lining which needs to be periodically refurbished. A complete re-polish of the refractory lining of the main flow path usually takes at least a week – during which time the corresponding flow outlet cannot be produced. In order to reduce the time that the outflow port cannot be produced, it has been proposed to replace the main flow path directly with a reverse flow path instead of re-shaping the refractory lining in situ. However, the size of the main runner of a modern blast furnace can be as high as, for example, a length of 2 〇 m, a width of 3 m, and a height of & and its weight can be as high as 400 mega. Obviously, replacing the main flow path with a reverse flow path can cause serious processing problems. In order to replace the main flow path, it has been conceived to use a crane that is generally available: however, in order to lift the heavy main flow path, the casting chamber machine and its supporting structure must be considerably reinforced. $: Due to the lack of blast furnaces for a long time The surrounding space is even =::: Moreover, under such difficult space constraints, the main body of the type blast furnace |, six f, L ^ towel has long dealt with such a heavy object as the main machine. danger. The invention also discloses the use of a lifting device comprising a vertical traction element which is flexible or rigid and which is fixed to a tapping floor or a flow path, as disclosed in EP 1 293 984. For lifting the main flow path vertically between a lower maintenance height and an upper divided ground plate height. A similar method is described in the patent DE 36 24 266. According to this patent, the vertical lifting elements are placed on the floor of the blast furnace machine. Although the prior art lifting devices disclosed in the patents of EP 〇 2 79 165 and DE 3 6 24 266 allow the replacement of the main flow paths, they require a cumbersome and expensive vertical lifting mechanism and must bear more serious The risk of An Wang. This is especially true if the main flow path is heavy and bulky.

Transport very heavy flow paths quickly and safely. This object is achieved in accordance with the invention to provide a tiltable bridge that can be placed in an operational position of the rear side. The bridge surface, and the flow path along which the inclined flow channel can be maintained along the inclined plane, two to the lower maintenance height, and vice versa, simply and quickly and safely replace the force required to move the flow channel is indeed small Wherein the manipulating device comprises a flow channel supported at the outlet of the shaft furnace which can be inclined to form an inclined plane ascending or descending. In other words, move and divide the ground plate height from above. This is the way to a heavy flow path in a casting chamber. Slide it along the tilting bridge vertically to lift it up. As a result, 1293984 moves along a sloping plane a very heavy, νMU + 士伽幻爪道 required drive mechanism to lift the flow path required for vertical lifting mechanism is simpler: troublesome and less expensive. Furthermore, moving the sinking along the tilt plane is obviously safer than lifting it vertically. A further advantage is due to all the main components of the operating device according to the invention; =: under: the grounding plate. In other words, the manipulation according to the present invention does not create a troublesome obstacle on the blade ground plate. - The particularly delicate and simple embodiment of the operating device comprises - a lower: a frame portion and an upper bridge portion '. These portions can be formed independently and 5 to form the inclined plane. Therefore, the lower bridge portion can be brought into a horizontal position at the lower service level 'which allows replacement at one: the flow path placed on the lower bridge portion. The upper bridge portion can be π into a horizontal working position at the height of the upper grounding plate, wherein: the flow passage on the upper bridge portion can be operated in the second outlet of the blast furnace. In order to facilitate the transport of the flow path along the tiltable bridge, the flow path is advantageously also supported on the flow path support trolley. Such a trolley system is, for example, a rail vehicle 'where the tiltable bridge includes a track 0 for guiding the rail vehicle, and the drive capable of using the tiltable bridge to move the trolley is better placed in the example. This drive mechanism contains a hydraulic jack. However, the drive mechanism can also comprise, for example, a winch or gear and rack system. In a preferred embodiment, the tiltable bridge includes a lower bridge 1293984=position and an upper bridge portion, the portions being individually pivotable and cooperative to form the inclined plane, and the hydraulic jack includes a coupling to The jack body in the lower bridge portion and a telescopic jack piston guided by the guiding mechanism in the bridge portion above the lower bridge portion (4). In order to support the trolley in the flow path on the lower bridge part, the two maintenance areas are provided in the bridge (the fourth part) and the side (4). Two::Easy to move the first-class support trolley from the lower part of the bridge to the middle of the two maintenance areas in the one-direction direction - and vice versa: the flow-supporting trolley is advantageously capable of winding In a preferred embodiment pivoting a vertical spindle, the tiltable bridge is tilted by facing at least one substantially horizontal spindle clock - preferably by at least =: The role of the top. It is advantageous to include at least one articulated strut = a piece of land used in the oblique and/or inclined position of the money. Attack, Zenggu I & safety, maneuvering the shock is advantageous to include a locking device for the 2:1 tiltable bridge. This type of locking device has two systems that allow the flow path or the flow path support trolley to be fixed in the oblique position ‘! #作位置。 Secondly, when the tiltable bridge is at its tilting position, the locking device fixes the flow path or the flow path support table to the upper bridge portion of the frame. In order to prevent the flow path from falling back without the inclined plane, the locking device advantageously has the function of locking the lock when the corresponding drive mechanism, such as the hydraulic jack, the already loaded road or the runner supports the weight of the trolley. 1293984 [Embodiment] Fig. 1 shows a cross-sectional view through a casting chamber of a blast furnace 10, a straight center and an outlet 12 and a main flow path associated with the outlet 12; : The test says that the 16 watch is not in the prayer room - the grounding plate 16.

Just as the second-bridge portion 24' of the second bridge portion is additionally provided with one or more struts 9〇 that can be removed. These struts % will support the track 46, supported in an inclined position, so that the second starter 72 is unloaded after the selected track "up to the tilt position" is possible 12 1293984 • Reference number 8G mark - Telescopic jack 8 (), which is used to drive the trolley 22 (or 32) along the inclined inclined plane, and when the operating device 2 is located in the flow passage replacement structure shown in Fig. 2 or SI 3 The inclined plane is formed by a support rail 46' 46. In the non-tilted structure of g|1, the contracted telescopic jack 80 is disposed on the inner side of the support rail 46. It should be noted that the hydraulic jack 71 62 Preferably, the double acting jack is adapted to resist the moment exerted by the telescopic jack 80 on the hinge post 5. In fact, when the elongated telescopic jack 80 is pushed on the bogie 22, the starter will therefore The first bridge portion 24 ± exerts an elongated tension. This compensates for this moment and thus prevents damage to the operating device 2 . As shown in enlarged detail in Figure 2, which is most clearly shown in Figure 2, the telescopic jack 8 includes one Carrier head 82 A bracket 84 below the runner support trolley 22 is loosely contacted to support the trolley 22 on an inclined plane. The carrier head 82 of the jack and the telescopic piston are fitted with guide wheels that are attached to the support rails 46, 46. 'The guide guides and supports the piston and the carrier head.' When the φ tiltable bridge 26 is located in the flow path replacing structure shown in Fig. 2 and the locking device 28 has been released, the trolley 22 supporting the flow path 14 to be replaced can be lowered in a controlled manner by the telescopic jack 80. Figure 3 shows the situation after the trolley 22 has completed its downward travel on the tilting bridge 26. This is achieved when the telescopic jack 80 is fully retracted. The trolley 22 is thus supported entirely on the lower bridge. When the post 90 is removed, the second starter 72 can pivot the lower bridge portion to its horizontal position. The first cart 22 supporting the worn runner 14 can thus be replaced by a second cart 32 supporting the re-brightened runner 36 13 1293984. This operation is performed in the pit 42. Figure 4 shows a plan view of the track in the pit 42. Two horizontal zones for parking and for re-sharpening, 〇0'102 are laterally provided on either side of the lower deck portion 34, and the k-track 106 is laterally placed at the site The track 4 〇 4 〇, get +... In this case, the first car 22 can be easily removed from the lower bridge portion 34 and the 筮-Δ, 弟一车 34 can be easily placed thereon. In order to allow the borrower to use the simple traction on a car 22, 32 to enter the lamp to replace a car 22 and 32 can be laterally tied to each other. The number of symbols 1〇8 is not used for multiple reamers that do not have some lateral traction of the trolley. Lateral stops 110 are placed on the lateral tracks 1〇6 to limit the lateral travel of the car 2 32, respectively. The end stop ah 114 is placed in the descending direction in the extended portion of the track 40 to limit the downward travel of the trolleys 22,32. The ® 4 also shows that a vertical jack 112' is disposed along the lower deck portion 34 for lifting the trolley 22 (or η) from the rail 4'', as described in the next paragraph. . Figure 5 shows the trolleys 22 and 32 in the pit 42 in cross section. In the exchange of the middle car 22, 32 is located in the pit 42 towel. In order to allow the lateral movement according to the figure as shown in Fig.*, the operation (4) of the trolley m can be mounted on a bracket 122, which can be two-vertical spindle Rotate. In order to change the operating wheel (10) from the longitudinal direction. See Figure 2 for the orientation of the trolley 22) entering the lateral direction (see the trolley 32 in Figure $), and the inverse ^^.., J..., the droughts 22 and 32 can be lifted by the vertical 112, respectively. When the trolley 22 or 32 is lifted, its operating wheel (2) can be rotated 9 degrees 'to thereby select the port 22 or 32 in the longitudinal and lateral movements ^ 14 1293984 to be lowered to its operating wheel 12 ,, This locks the bracket 122 in the selected direction of motion. Figure 5 also shows that the flow passages 14, 36 are mounted in the trolley 22 or 32 to have a peripheral gap. In fact, the runners 14 and 36 are respectively mounted on the slide plates or running rods inside the carriages 22 and 32 ( Not shown), and is fixed to the sliding plate or running bar at a special point (not shown) along its length. This type of mounting allows the flow passages 14 and 36 to thermally expand in the forward direction of the flow outlets > Figure 5 shows the structure of the lower bridge portion 34 in cross section. More specifically, the lower deck portion 34 includes two longitudinal parallel beams 13 〇, such as two steel beams. These girders 130 are joined together along their length by a plurality of upper and lower ten members 132, 134 which are welded to the inner wall 136 of the girders 130. A space system is provided between the girders 13 〇 and the upper and lower cross members 132, 134 for extension of the telescopic jacks 8 。. The support wheel 92 for the jack 80 is guided and supported in a section 138 that is secured to the inside of the bridge portion 24, 34. For reasons of stability, the track 40 is welded directly over the outer wall 14 of the girder 130. The upper bridge portion 24 has a similar structure. It will be appreciated that this configuration results in a sturdy, reliable and compact tilting bridge. When the trolley 22 supporting the flow path 14 to be replaced has been lifted and replaced by the trolley 32 supporting the re-polished flow passage 36 on the rail 4 of the lower bridge portion 34, the latter will be lifted again. Used to form the inclined bridge 26. Before the trolley 32 is lifted, its structure is the same as that of Fig. 3 (except for the replaced flow path and the replaced trolley). After the brake 15 1293984 32 has been lifted by the telescopic jack 8 ,, the structure shown in Fig. 2 can be applied as a corresponding change. τ' #Returns the upper and lower bridge portions 22, 34 to the horizontal position by the first starter 62 or alternatively by the second starter 72, the struts 9 are removed in advance and the struts 64 are then unfolded . When going to the drinking field to re-sharp the main flow path 36 to replace the main flow path ι4, the structure of the operating device 20 will again correspond to the figure, ^ shows the re-polished The flow path 36 is located outside of the operating position in front of the outflow port 12. Referring back to Figures 1 and 2, it is noted that the locking device 28 provides an important function. In fact, the 1+ and f I systems ensure that the main flow passage 14 is tightly (4) in front of the π 12 in the operating position, and in the flow passage replacement structure of the inclined bridge %, the flow path support trolley 22& The upper bridge portion 24 moves.
