The invention relates to a positioning device for positioning a

Container section of a process plant.

A process plant, such as for cryogenic separation, may comprise a rectification or air separation column. Such

Rectification or air separation column has a cylindrical container in which so-called packages are arranged. The container is constructed of so-called container sections. Each container section may have multiple container sections. For producing such a container, it is necessary to connect several container sections firmly together, for example to weld. For the container production are firmly connected to the container sections

Round retaining rings used. Each round ring ring rests on a turning device. To edit the container sections or to connect several

Container sections with each other, these can be rotated by means of the rotating devices. In this case, a torque is applied to the associated round retaining ring for rotating the container sections of each rotating device by means of frictional engagement. For each container diameter is also a corresponding

Round retaining ring made.

Against this background, the object of the present invention is to provide an improved positioning device. Accordingly, a positioning device for positioning a

Positioning Device 1. FIGS. 7 and 8 show enlarged views of the positioning device 1, respectively. Reference will now be made to FIGS. 1 to 8 simultaneously.

The positioning device 1 can also be referred to as a rotary device, round support device or rotary and round support device. The container section 2 can also be referred to as a jacket section or jacket section. Several

Container sections 2 can form a container section and several Container sections may form a container of a process plant, in particular for air separation. The container portion 2 is hollow cylindrical or tubular and may have a diameter of several meters and a length of several meters. The container portion 2 is formed rotationally symmetrical to a symmetry or central axis M ₂ .

The positioning device 1 comprises a guide ring 3 with an outside, circumferential toothing 4. The guide ring 3 is tubular. The container portion 2 can be arranged within the guide ring 3. That is, the central axis M _{2 of} the container portion 2 may be coaxial with a symmetrical or central axis M _{3 of} the

Be positioned guide ring 3. The guide ring 3 is rotationally symmetrical to the central axis M _{3 is} formed. The guide ring 3 can be used for container sections 2 of different diameters. The guide ring 3 has in addition to the toothing 4 at least one, but preferably two each on both sides of the toothing 4 arranged cylindrical outer side or first running surfaces 5, 6. Furthermore, the guide ring 3 comprises two cylindrical inner or second running surfaces 7, 8 facing the container portion 2. Perforated running surfaces 9, 10, in particular a third running surface 9 and a fourth running surface 10, are provided on the front side of the guide ring 3. The guide ring 3 may be made of a steel material.

The guide ring 3 is firmly connected to the container portion 2. For this purpose, the positioning device 1 comprises a fastening ring 11. The fastening ring 11 is formed rotationally symmetrical to the central axis M ₃ . The container portion 2 is disposed within the fixing ring 11. The attachment ring 11, which is preferably made of a steel material, can be individually to a

Outer diameter of the container portion 2 adapted. That is, for each container portion 2, a fixing ring 11 associated therewith can be manufactured. The mounting ring 11 can form and / or frictionally with the

Be connected container section 2. That is, the fixing ring 11 may be clamped on the container portion 2.

At the container portion 2 Abstützbleche 12 can be welded on the outside. The number of support plates 12 is arbitrary. For example, four evenly distributed over a circumference of the container portion 2 support plates 12 may be provided be. The support plates 12 have centrally a recess into which the

Fixing ring 11 engages positively. As a result, the container portion 2 is fixed to the fixing ring 11 in the direction of the central axis M ₂ , that is, in the direction of an x-axis x of a coordinate system having an x-axis x, a y-axis y and a z-axis z. In order to prevent a rotation of the container portion 2 relative to the fastening ring 11, can on the mounting ring 11th

Driver elements 13, 14 may be provided, which are arranged on both sides of at least one of the support plates 12. The driver elements 13, 14 may be screwed or welded to the mounting ring 11.

Furthermore, an optional driver plate 15 can be firmly connected to the container section 2. The driver plate 15 may be welded or screwed to the container portion 2. The driver plate 15 engages positively in a provided on the mounting ring 11 recess. With the help of the driver plate 15, as with the help of the driver elements 13, 14, a torque DM without slippage can be transmitted from the mounting ring 11 to the container portion 2. The

Recess, in which the driver plate 15 engages positively, can be provided in or on a parting plane E of the mounting ring 11. Of the

Fixing ring 11 can be divided at the dividing plane E centered in two half-shells 16, 17. The half-shells 16, 17 can be screwed together and / or pinned together by means of dowel pins.

The guide ring 3, like the fastening ring 11, can be divided at the dividing plane E into two half-shells 18, 19, which enclose an angle of 180 °, in the middle. As a result, the container portion 2 can be easily in the guide ring 3 and the mounting ring 11 in and out of this lift out. The half-shells 18, 19 can be bolted together and / or pinned. In order to align the half-shells 18, 19 with each other during the assembly of the guide ring 3, each half-shell 18, 19 can have an engagement section 20 and a counter-engagement section 21, which are adapted to intermesh positively. Furthermore, each half-shell 18, 19 may also have dowel pins or guide pins 22, 23 which are adapted to be provided in the respective other half-shell 18, 19

Holes intervene positively. The positioning device 1 further comprises at least one optional intermediate ring 24, 25. The number of intermediate rings 24, 25 is arbitrary. For example, two or no intermediate ring 24, 25 may be provided. The intermediate rings 24, 25 are divisible at the parting plane E in each other screwed and / or pinned half shells 26 to 29. Furthermore, the positioning device 1 may have an optional adjusting ring 30, which is also divisible at the parting plane E in two half-shells 31, 32. With the help of the adjusting ring 30, the guide ring 3 against the

Container section 2 are tilted. That is, with the aid of the adjusting ring 30, the central axes M ₂ , M ₃ can be aligned collinear with each other. The adjusting ring 30 is fixedly connected to the intermediate ring 25, for example screwed. each

Half shell 31, 32 of the adjusting ring 30 may have a plurality of adjusting elements 33,

in particular threaded pins, which pass through in the guide ring. 3

provided recesses 34 are passed. On the adjusting elements 33 each nuts for displacing the adjusting ring 30 relative to the guide ring 3 can be screwed. The displacement of the adjusting ring 30 is indicated by means of an arrow 35. When displacing the adjusting ring 30 slides an outer surface 36 of the adjusting ring 30 on an inner surface 37 of the guide ring 3. In particular, the adjusting ring 30 can be moved with the uniformly distributed over its circumference adjustment 33 in the x-axis x. By different displacement values, a possibly inclined central axis M _{2 of} the container portion 2 can be aligned horizontally. The adjusting elements 33 can be designed mechanically, for example with a threaded system, hydraulically or electrically.

The mounting ring 11, the intermediate rings 24, 25 and the adjusting ring 30 can be firmly connected to each other by means of screws 38. The intermediate ring 25 may also be connected directly to the guide ring 3, omitting the adjusting ring 30. The mounting ring 11, the intermediate rings 24, 25, the adjusting ring 30 and / or guide ring 3 can be equipped with grooves and feather keys for torque transmission, so that between the mounting ring 1 1, the intermediate rings 24, 25, the adjusting ring 30 and / or the guide ring 3 no slip can occur in the circumferential direction. The mounting ring 1, the intermediate rings 24, 25, the adjusting ring 30 and / or the guide ring 3 are provided on faces with chamfers to ensure easier insertion into each other. The guide ring 3 can omit the

Adjustability also be formed integrally with the adjustment ring 30. The half shells 16 to 19 and 26 to 29 can be adjusted by an optional mechanical adjustment device, such as a thread or an eccentric, perpendicular to the parting plane E. As in the parting plane E, a gap must be provided according to the diameter tolerances of the container portion 2, to a clamping of the

Container section 2 to allow this value must be compensated for different gap size to the central axis M ₂ centrally, that is to keep collinear to the central axis M ₃ . The holes in the screws 38 are made correspondingly large. Only the voltage applied to the container section 2 mounting ring 11 has an open gap in the parting plane E and must be aligned accordingly centric. In the further outer intermediate rings 24, 25, the adjusting ring 30 and the guide ring 3 between the flange surfaces of the half-shells 18, 19 and 26 to 29 at the parting plane E compensating plates inserted between the

Fixing ring 1, the intermediate rings 24, 25 and the adjusting ring 30 provided bearing surfaces 39 are interlaced. The positioning device 1 comprises at least one shown in FIG. 9

Positioning device 40 which may be positively engaged with the guide ring 3 in order to rotate it about the x-axis x. Positioning device 1 may include a plurality of positioning devices 40. The positioning device 40 has a frame 41. The frame 41 may have two frame members 42, 43 spaced apart from each other and fixedly connected to each other. The

Frame elements 42, 43 each comprise two engagement portions 44, 45, which are adapted to the positioning device 1 associated guide rails 46, 47 positively engage around. The guide rails 46, 47 may have a mushroom-shaped cross-section. The guide rails 46, 47 extend in the direction of the x-axis x, that is, parallel to the central axes M ₂ , M ₃ . The engagement portions 44, 45 may include rollers and / or sliding surfaces. The positioning device 40 is thereby fixed immovably to the guide rails 46, 47 in the direction of the y-axis y and in the direction of the z-axis z and linearly displaceable along the guide rails 46, 47 in the direction of the x-axis x. As a result, the engagement portions 44, 45 can have positive and negative forces in the direction of the y-axis y and in the direction of the z-axis z and moments about the x-axis x, the y-axis y and the z-axis z take, so that the container portion 2 can be held with a single positioning device 40 without tilting. On the frame members 42, 43 two spaced-apart shafts or axes 48, 49 are mounted, whose central axes are oriented parallel to the central axis M ₃ . Each axle 48, 49 includes two rotatable support rollers 50, 51. The support rollers 50, 51 may be rotatable relative to the axles 48, 49 or the axles 48, 49 may be rotatable relative to the frame members 42, 43. The support rollers 50, 51 are adapted to roll on the first running surfaces 5, 6 of the guide ring 3. The positioning device 40 further comprises two pairs of adjustable side guide rollers 52, 53, which are adapted to the front side

Unroll treads 9, 10 of the guide ring 3. As shown in FIG. 9 with the aid of arrows, the side guide rollers 52, 53 are displaceable in the direction of the y-axis y and in the direction of the z-axis z, that is, in the direction of the center axis M ₃ and away from it. In this way, the positioning of the side guide rollers 52, 53 relative to the front-side running surfaces 9, 10 can be adjusted. The front-side running surfaces 9, 10 may also be inclined and, together with side guide rollers 52, 53 in the form of tapered rollers, ensure a particularly low-friction and low-wear running.

The positioning device 40 also includes two pairs of adjustable

Hold-down rollers 54, 55, which are adapted to roll on the second running surfaces 7, 8 of the guide ring 3. Central axes of the hold-down rollers 54, 55 are oriented parallel to the central axis M ₃ . As shown in FIG. 9 with the aid of arrows, the hold-down rollers 54, 55 are displaceable in the direction of the x-axis x. In this way, after placing the guide ring 3 on the support rollers 50, 51, the hold-down rollers 54, 55 are displaced so that they surround the guide ring 3. As a result, tilting of the guide ring 3 is excluded.

In particular, the hold-down rollers 54, 55 and the side guide rollers 52, 53 can be moved away from the guide ring 3 in the direction of the arrow. This may be necessary when multiple container sections 2 are welded together on a plurality of positioning devices 40. Individual positioning devices 40 can then be converted into floating bearings so that the static determination of the system is granted by a single positioning device 40 acting as a fixed bearing.

In addition, for maintenance, the guide ring 3, the intermediate rings 24, 25th and / or the adjusting ring 30 are better lifted out of the positioning device 40.

A drive element 56 of the positioning device 40, in particular a pinion or a drive gear, has a counter toothing 57, in particular a

External toothing, which is adapted to engage positively in the toothing 4 of the guide ring 3. The drive element 56 is rotatably mounted on the frame elements 42, 43 by means of a shaft 58. A drive 59, for example an electric motor or a hydraulic motor, is configured to drive the drive element 56. The drive 59 may be coupled to a control device in order to position the drive element 56 and thus also the guide ring 3 with angular accuracy. The drive 59 is optional. The drive element 56 can also be rotated manually. The positioning device 40 may also include a hydraulic or electric lifting system.

With the help of the positioning device 40, the guide ring 3 and thus also the container portion 2 fixedly connected to the guide ring _{3 are} rotatable about the x-axis x or the center axes M ₂ , M ₃ . In particular, the container portion 2 can be rotated by an arbitrarily large rotation angle α. The fact that the counter teeth 57 of the drive element 56 engages positively in the toothing 4 of the guide ring 3, the container portion 2 can be rotated slip-free and positioned at an angle. An angle-precise positioning means that the desired rotation angle α can be adjusted without slippage and with high accuracy by means of the positioning device 40. This allows the container portion 2 for

Machining, that is, for the introduction of holes or cutouts, for

Welding with another container section 2 or the like, very precisely aligned and rotated at a constant rotational speed even with asymmetrically arranged internals. When rotating the container portion 2, the torque DM is applied to the guide ring 3.

Characterized in that the central axis M _{2 of} the container portion 2 horizontally, that is oriented in the direction of the x-axis x, a plurality of container sections 2 can be assembled in a correspondingly low assembly hall to a container section. On a vertical and thus space-consuming positioning of

Container sections 2 can be dispensed with. The fastening ring 1 1, the Guide ring 3, the intermediate rings 24, 25 and the optional adjusting ring 30 are precisely guided and driven, being different for different diameters

Container sections 2 of the guide ring 3, the intermediate rings 24, 25 and the adjusting ring 30 can be assembled from a kind of kit. Only the

Fixing ring 11 must be individually adapted to the container section 2.

Furthermore, for a special diameter, a relatively small diameter-specific adapter ring may be required.

Advantageously, the central axis M _{2 of} the container portion 2 is also at

different diameters of different container sections 2 always arranged collinear to the central axis M _{3 of} the guide ring 3. Because of that

Fastening ring 11 engages positively in the support plates 12, a tilting of the container portion 2 is prevented, even if this in only one

Positioning device 40 is added. Furthermore, the support rollers 50, 51, the side guide rollers 52, 53 and the hold-down rollers 54, 55 form-fit the guide ring 3 so that it can not tilt and is also fixed along the x-axis x.

The fastening of the fastening ring 11 and, for example, the inner

Intermediate ring 24 on the container portion 2 can by means of one of

Positioning device 1 associated and shown in Figs. 10 to 12

Mounting device 60 done. The mounting device 60 comprises a foundation 61. The foundation 61 may be a concrete foundation, a steel sheet or a hall floor. The foundation 61 is horizontally aligned and level. The mounting device 60 comprises at least three adjustment elements 62 to 64, which are distributed uniformly over a circumference of the container portion 2. On the adjusting elements 62 to 64 of the intermediate ring 24 and / or the mounting ring 1 can be placed.

As shown in FIG. 12 with the aid of arrows, the adjusting elements 62 to 64 are displaceable horizontally, that is, toward or away from the central axis M ₂ . For this purpose, each adjusting element 62 to 64 has a horizontal module 65.

Furthermore, each adjustment element 62 to 64 also includes a vertical module 66.

Ring supports 67 of the adjusting elements 62 to 64, on which the intermediate ring 24 and / or the mounting ring 1 1 rest, are using the respective

Vertical module 66 height adjustable, that is, along the central axis M ₂ displaced. The mounting device 60 also includes, for example, three positioned on the base 61 container portion supports 68, each with a piston 69. On the movable piston 69 is an end face of the container portion. The end face need not be even or perpendicular to the central axis M ₂ .

For mounting the fastening ring 1 1 and / or the intermediate ring 24 on the container portion 2, the container portion 2 is first on the

Container section supports 68 provided. The pistons 69 of the Behälterabschnittauflagen 68 are electrically or hydraulically extended in each case until the

Container section 2 and the center axis M ₂ thereof is positioned perpendicular to the foundation 61. The ring supports 67 are then positioned with the aid of the horizontal modules 65 of the adjusting elements 62 to 64 electrically, manually or hydraulically radially to the container portion 2, that the fastening ring 1 1 and / or the

Intermediate ring 24 can be placed on this. Subsequently, the mounting ring 1 1 and / or the intermediate ring 24 are placed on the ring supports 67 and moved with the vertical modules 66 electrically or hydraulically to the desired height and also aligned horizontally parallel to the foundation 61.

The half shells 16, 17 and / or 26, 27 are clamped to the container section 2. Subsequently, the support plates 12 are fixedly connected to the container portion 2, for example, welded or screwed with this. Of the

Fixing ring 1 1 is displaced in the intermediate ring 24 so that an outer side of the intermediate ring 24 is centric to the container section 2. The mounting ring 1 1 and the intermediate ring 24 are then screwed together. The mounting ring 1 1 and the intermediate ring 24 are now exactly to the central axis M _{2 of} the

Container portion 2 aligned and can, for example, in the split

Guide ring 3 are lifted or placed together with the guide ring 3 on the positioning device 40. In addition, also the second intermediate ring 25, the adjusting ring 30 and the guide ring 3 can be attached to the container portion 2.
