AI Technical Summary
The assembly of heavy loads, such as complex reactor vessels, in support structures is complex, costly, and often compromises optimal design due to site-specific constraints, particularly in the metal extraction industry where CO2 emissions are minimized using renewable energy methods, necessitating safer, more time-efficient, and cost-effective installation methods.
A method involving a strand lifting system and a Self-Propelled Modular Transporter (SPMT) to pivot and secure the reactor into the support structure, allowing for controlled and safe lifting of the reactor from a horizontal to an upright position, reducing crane usage and assembly time by initially building the support structure to an intermediate height and then completing the assembly with the lifting system.
This method enables the safe, efficient, and cost-effective installation of heavy reactors, minimizing crane usage and allowing for optimal design without site-specific restrictions, significantly reducing assembly time and costs while ensuring safe and controlled lifting of reactors weighing over 1000 tons to operational heights.

Abstract
Description
[0001] Method for installing a heavy load in a supporting structure and a system constructed according to the method
[0002] The invention relates to a method for installing a heavy load in a support structure, in which at least one heavy load is transported upwards in this support structure and fastened so that it can be fixed in the operating position, as well as to a method for installing the support structure and a system, this according to the preamble of claims 1, 10 and 14 respectively. In order to sustainably minimize environmentally harmful emissions in metal production, as well as in the iron and steel industry, in the long term, efforts are underway to use new technologies in which CO2 emissions can be virtually eliminated. For example, in the extraction of iron from ores, new processes are sometimes sought in the production processes, in which direct reduction of iron ore can preferably be carried out based on renewable energies.Natural gas or, even better, hydrogen is ideal for this purpose, as it enables the reduction process to be carried out largely without CO2 emissions.
[0003] For this purpose, new facilities are being built, each of which, similar to blast furnaces, features a complex reactor vessel as a heavy load within a supporting structure or similar. The facility for operation with the complex reactor vessel is designed to ensure optimal logistical flow of iron ore and other components, as well as energy, into the reactor, and also to ensure the cooling of the reactor walls.
[0004] Such complex reactor vessels can each have empty weights of over 1,000 tons and are therefore usually assembled at the operating site from a large number of individual parts in the support structure and simultaneously secured within this support structure. This procedure is complex and, due to the use of large cranes for erecting the support structure and assembling and installing the reactor within it, is associated with correspondingly high costs. Furthermore, the reactor must be designed in such a way that it can be assembled into the support structure or similar structure, taking the circumstances into account, which can lead to a situation where it cannot be optimally designed.
[0005] The invention is based on the object of creating a method for installing a heavy load in a supporting structure, by means of which such installation in the operational state in the supporting structure can be carried out more safely, more quickly and thus more cost-effectively and the heavy load can be designed in such a way that restrictions such as those required for assembly in the supporting structure do not have to be taken into account.
[0006] This object is achieved according to the invention by the features of claim 1, claim 10 and claim 15.
[0007] In the method according to the invention, the heavy load to be transported is, in particular, a reactor for metal extraction in a state that is at least almost ready for operation. This heavy load is moved horizontally by a transport means up to or partially into the support structure and is then pivoted upwards by a lifting system mounted in the support structure, preferably a strand lifting system, and pulled up into the support structure and secured to its operating position. For pivoting up into the upright position, this heavy load is tiltably mounted on the transport means and is lifted from the transport means by this lifting system.With this method according to the invention, this heavy load, which is in particular a reactor for metal extraction, can be guided to the support structure in the assembled state, swung into this support structure in a safe manner and hoisted into the operational position, despite the enormously high weight load, which can vary.
[0008] Preferably, a known SPMT (Self-Propelled Modular Transporter) is used as the means of transport, which consists of a platform with such a large number of axles and wheels that the load per wheel corresponds to its possible weight load.
[0009] The lifting system mounted in the supporting structure preferably uses a strand lifting system, which is also known per se. Such strand jacks are suitable for lifting or carrying extremely heavy loads, and by using several of them pulling simultaneously, this heavy load can be hoisted into the operating position.
[0010] Conveniently, the heavy load, which is equipped with a removable reinforcement device at the front, is moved through the transport means partially into the interior of the support structure, and at least one longitudinal element of the lifting system, preferably in the form of a strand, is connected to a connection point on the reinforcement device of the heavy load. This extremely simple coupling allows this heavy load to be connected to the lifting system and swung upwards without complicated manipulation. A tilting rod, lying on the transport means and articulated to it, is releasably attached to the underside of the heavy load in its horizontal transport position. This tilting rod is pivoted upwards together with the heavy load and, before the heavy load reaches the upright position, strikes a stop on the underside, stopping the swiveling of the heavy load.This tilting rod ensures that the reactor, with its outer shape formed with different diameters, rests in several places above the platform of the transport means in the tilting rod and is mounted in a horizontal orientation on this tilting rod or on the transport means, similar to a torpedo.
[0011] It is very advantageous to control the transport device in such a way that, when the heavy load is swiveled upwards, it travels partially into the interior of the supporting structure at a speed corresponding to the swivel movement. This ensures that the connection point on the container and at least one longitudinal element of the lifting system acting on it move approximately vertically upwards within the supporting structure, thus ensuring a controlled and safe swiveling of the heavy load.
[0012] For lifting the heavy load after it has been lifted from the transport means in an upright position, the invention provides that additional longitudinal elements of the lifting system are coupled, preferably on the opposite side to the already connected longitudinal element(s) of the heavy load, to a connection point of the reinforcement device in order to apply the necessary tensile force to the heavy load. According to the invention, the support structure is constructed to a specific intermediate height, and then this lifting system is mounted on the support structure. Consequently, the heavy load can then be transported and secured to this intermediate height by means of the lifting system. Simultaneously with the
[0013] The crane system, which has already installed the supporting structure up to this intermediate height and the lifting system on top of it, allows the installation of further loads up to their full height. This results in a considerable time saving during the entire installation, which also increases the operating time of the
[0014] crane system can be reduced to a minimum.
[0015] The invention and further advantages thereof are explained in more detail below using exemplary embodiments with reference to the drawings. They show:
[0016] Fig. 1 is a perspective side view of the lower part of the plant according to the invention with a heavy load designed as a reactor in a support structure as well as a means of transport carrying the heavy load and above the heavy load the

[0019] Fig. 3 is a perspective side view of the reactor and the lifting system according to Fig. 1, wherein the reactor is shown in the raised position on the transport means without the support structure; and
[0020] Fig. 4 is a perspective view of the completed plant according to Fig. 1 with the reactor installed in the support structure and a cooler tank as well as a crane system next to the plant.
[0021] Fig. 1 to Fig. 4 show a schematic diagram of a system 10 with a support structure 15 and a heavy load to be installed in the latter as a reactor 20. This support structure 15 consists of a lattice-like structure as a basic framework with longitudinal and transverse elements 16, 17, wherein it is designed with a hollow space 18 on the inside and, due to the required height, as a tower. As mentioned, it is only shown schematically. In any case, it must be provided with such statics that it can permanently absorb the enormous load forces of the heavy load to be installed. This support structure can be designed differently depending on the circumstances and requirements and can be located freestanding in a factory area or be designed as part of a building with several floors or the like.
[0022] In the method according to the invention, the heavy load to be transported is, in particular, a reactor 20 for metal extraction in a state that is at least approximately ready for operation. This reactor 20, as a heavy load, is moved horizontally by a transport means 11, preferably by an SPMT (Self-Propelled Modular Transporter), up to or partially into the cavity 18 of the support structure 15. It is pivoted upwards by a lifting system 25, preferably a strand lifting system, mounted in the support structure 15, and pulled up and secured in the support structure 15 to its operating position. For pivoting upwards into its approximately upright position, the reactor 20 is tiltably mounted on the underside of the transport means 11 and is pivoted about an articulated connection 31.
[0023] The invention is characterized by the fact that it allows, in particular, such a reactor 20, in a nearly operational state with an empty weight of over 1,000 tons, to be lifted into the required operating position to a height of, for example, 80 m in a completely new way. The reactor is, in particular, one that processes iron ore through direct reduction using renewable energy sources and extracts iron from it in a multi-stage process, primarily for the metal industry.
[0024] The reactor 20, designed as a container, with its torpedo-like outer shape, consists of a front stepped cylindrical section 22 with a head part 21 with several upwardly projecting connecting pieces 2T, which is not explained in more detail, as well as a hull 23 with an enlarged diameter, with a support frame 39 and a conical lower part 24 extending approximately to a point.
[0025] On the cylindrical section 22, a reinforcement device 26 is mounted on its outer shell, which is installed either permanently or, advantageously, removably. It comprises two spaced-apart reinforcement elements 27, 28, which are removably attached as rings to the outer circumference of the reactor 20 and are connected to one another by at least one connecting web 29. Two spaced-apart connection points 32, 33 are advantageously protruding on opposite sides of the front reinforcement element 27, which can be connected to longitudinal elements 34 of the lifting system 25.When swiveling up the reactor 20, only the two connection points 32 on its upper side need to be coupled with longitudinal elements 34, while the opposite connection points 33 are only connected to such longitudinal elements 34 after swiveling for pulling up the reactor 20, so that this lifting system 25 is able to lift the reactor 20 up to its final position.
[0026] In addition, the reinforcement elements 27, 28 are each assigned an adjustable tensioning device 40 (not explained in detail) on the outside of the reactor, each consisting of an elongated tensioning element 37 and a tensioning element 36 coupled to the elongated tensioning element, each generating a selectable tensile stress in its longitudinal direction. At each of the four connection points 32, 33, one such tensioning element 37 engages with one end, which extends parallel to the axial direction of the reactor and is held at the other end by the annular support frame 39. These tensioning devices 40 can be used to coordinate with one another to generate tensile forces on the front reinforcement element 27 in the opposite direction to the lifting force of the longitudinal elements 34, in order to counteract this lifting force on the reinforcement element 27.
[0027] This illustrated reactor 20 can, of course, be shaped differently than shown. For example, the body 23 and the upper cylindrical section 22 with the head section 21 could be assembled first, followed by the lower section 24. Likewise, this reinforcement device 26 can also be equipped, for example, with only one reinforcement element and without these tensioning devices 40. Depending on the weight of the heavy load, fewer or more than four such connection points 32, 33 can be provided.
[0028] As can be seen from Fig. 1, the front head part 21 of the reactor 20 with the reinforcing element 27 of the reinforcing device 26 is moved by the transport means 11 into the interior of the support structure 15 and the two longitudinal elements 32 of the lifting system 25, which are preferably designed as strands, are connected in this position to the respective connection point 32 at the reinforcing device 26 and the reactor 20 is pivoted upwards as a heavy load by actuating the lifting system.
[0029] The transport means 11 with an upper platform 1T is preferably formed by two independently movable transport units 12, 13, which together transport the heavy load partially to the support structure 15, as illustrated in Fig. 2. These transport units 12, 13 consist of such a plurality of axles and wheels that the load per wheel corresponds to the predetermined weight load, wherein the axles are each individually driven. After the longitudinal elements 32 of the lifting system 25 are connected to the reactor 20 and its lifting, the front transport unit 12 is removed, while the rear transport unit 13, with a tilting rod 45 articulated to it, moves inside the cavity 18 of the support structure 15 and with it the reactor is pivoted upwards in the cavity.The reactor 20, similar to a torpedo, rests with its outer shape formed with different diameters above the platform 11 of the transport means 11 at several preferably flat points of the tilting rod 45 and is securely supported on this tilting rod and on the transport means during approach in a horizontal orientation. This box-shaped tilting rod 45 is composed of longitudinally and transversely connected support elements 48, 49, this articulated connection 31, and a support element 52 that holds the support frame 39 of the reactor 20 on the underside. This tilting rod can be designed differently depending on the outer shape of the heavy load and can consist of several modules.
[0030] This rear transport unit 13 of the transport means 11 is moved into the interior of the support structure when the reactor 20 is pivoted upwards at a travel speed controlled corresponding to the pivoting speed, so that the connection point 32 at the reactor and the longitudinal element 34 of the lifting system 25 engaging therewith move approximately vertically upwards in the support structure 15 and the reactor is pulled upwards with a linear pivoting movement and no disturbing vibrations occur in the process.
[0031] The reactor 20 is pivoted up to a position, as shown in Fig. 1, in which the tilting rod 45 rests with its underside opposite the articulated connection 31 against at least one stop 43 on the transport unit 13. Then, the two longitudinal elements 34 of the lifting system 25 on the other side are pivoted to the connection points 33 of the reinforcing device 26 in addition to the already connected longitudinal elements 34. The reactor is pivoted up to this inclined position and not into the upright position so that it does not tip over to the other side. In principle, however, it could still be pivoted up to an almost upright position and the additional longitudinal elements 34 then attached.
[0032] This articulated connection 31 on the transport means, as well as the tilting linkage 45, are then detached from the reactor and dismantled so that it can be lifted by the longitudinal elements 34 with equal amounts of force. Additional longitudinal elements (not shown) are provided, which are articulated at connection points 38 on the support frame 39 below the fuselage 23, so that the reactor 20 can be guided through the lifting system 25 to its final position and secured in the support structure.
[0033] For this purpose, the lifting system 25, mounted at a specific height in the support structure 15, is provided on the inside with a cavity 44' through which the reactor 20 can be lifted as a heavy load to the operating position and secured therein, as can be seen in Fig. 4 for the fully erected plant 10. The reactor 20 is pulled up over a partial height through the cavity 44' in the lifting system 25 into the operating position by the longitudinal elements 34 of the lifting system 25, which are to be connected in the central region of the reactor 20.
[0034] Fig. 3 shows the lifting system 25 arranged in the support structure 15, in which a strand lifting system is preferably used. This lifting system 25 consists of a base frame 44 carried on the support structure 15, of solid cross beams 46, 47 standing thereon in pairs, and of several lifting units 50, 51, in each of which these longitudinal elements 34 are held displaceably in their longitudinal direction. The one lifting unit 50 and the two cross beams 46, or the other lifting unit 51 and the two cross beams 47, are positioned on the base frame 44 such that the longitudinal elements 34 extending through them and hinged at the connection points 32, 33, and 38 of the reactor 20 are aligned approximately vertically in order to avoid bending moments in these longitudinal elements, which are usually manufactured as strands.
[0035] Essentially, these lifting units 50, which are known per se and not shown in detail, each consist of a hydraulic or pneumatic piston-cylinder unit which is fixed to one of the cross members 46, 47 and has a central through-opening on the inside for receiving one or more longitudinal elements 34. The cylinder is provided with an annular chamber in which the sleeve-shaped piston is guided in the axial direction. At the upper end of the piston and at the lower end of the cylinder, respectively, a clamping device with radially adjustable clamps is provided for holding the longitudinal element(s) 34 in place. When the piston is retracted, its clamps hold the longitudinal element 34 in place, and a medium is pressed into a chamber in the cylinder by a pump, so that the piston and with it the longitudinal element are moved upwards.As soon as the piston is extended, the open clamps on the cylinder are closed and those on the piston are opened, before the latter is then retracted. This process is repeated until the heavy load to be lifted has reached its final position. When the heavy load is lifted, these strands are moved upwards through and beyond the lifting units 50 and can be accommodated in straight or rounded guides above the lifting system 25 (not shown in detail). The control of the multiple piston / cylinder units is coordinated synchronously, which can be achieved through pressure equalization to achieve even load distribution.
[0036] It goes without saying that lowering the heavy load with these lifting units 50 is also possible in the opposite direction, although this is not explained in detail. Accordingly, the individual steps for lowering would have to be performed in reverse order.
[0037] The method according to the invention also extends to the installation of the support structure 15 for receiving the heavy load, wherein the support structure 15 consists of these stackable longitudinal and transverse elements 16, 17 and / or other support elements, which are erected on a vehicle 59 by at least one known crane system 55 with several lattice masts 56, 57, 58, as illustrated in Fig. 4. Very advantageously, the support structure 15 is erected to a certain intermediate height and then the lifting system 25, of which this base frame 44 can be seen, is mounted on the approximately half-built support structure 15. The reactor is then transported as a heavy load by the lifting system 25 to this intermediate height and secured.Practically simultaneously, the support structure 15 is installed to its full height by the crane system 55, the heavy load to be transported being, in particular, this reactor 20 for metal extraction in a state that is at least almost ready for operation. Instead of the crane system 55 shown, this installation of the support structure 15 to its full height can also be carried out in the manner disclosed in Swiss patent application no. CH000608 / 2023, in which the support structure could also be fully installed to the top at the same time as the heavy load is being installed. At least one crane is lifted from the ground area to the top of the support structure 15 and moved onto a flat support for its operation. However, the crane could also already be installed at this intermediate height and the lower part of the support structure 15 could have been erected with it beforehand.Using a crane and a lifting system, preferably several strand jacks, the supporting structure can be erected in stages by mounting the longitudinal and transverse elements 16, 17 and a lifting system on top of the crane. The installed lifting system, connected to the support by strands, can then lift the crane one stage at a time and then build the next stage of the supporting structure by hoisting the longitudinal and transverse elements 16, 17 from the ground level to the top of the supporting structure 15.
[0038] The reactor 20, lifted up within the support structure 15 to the lifting system, is guided through this frame-shaped lifting system and, with the support frame 39 attached to its outer shell, is secured below the fuselage 23, preferably at this intermediate height in the support structure 15. The transport means 11 is moved away after the heavy load has been lifted, and additional heavy loads can be fed into the support structure with it. While the support structure 15 is completed by the crane system 55 to its total height above the installed heavy load, additional components, such as at least one cooler tank 60, support elements 62, platform floors 61, etc., can be lifted and installed as additional heavy loads in the lower area or below the reactor using the lifting system 25.Once the reactor is fixed in the support structure 15, the same transport means for feeding and the same longitudinal elements 34 of the lifting system 25 as for lifting the reactor can also be used, advantageously those associated with the lifting units 51 at the cross beams 46, because these extend outside the outer shell of the reactor.
[0039] By simultaneously mounting it on the lower and upper sections of the support structure 15, the first platform in the upper construction section is used as a protective platform 63. This platform is reinforced with additional protective measures to protect the people working below.
[0040] The lifting system 25 with the crossbeams 46, 47, temporarily mounted at this specific height in the support structure 15, is preferably dismantled again after the heavy load and other components have been completely installed. The support structure and the area surrounding it are designed such that this lifting system 25 with the crossbeams 46, 47 can be reinstalled in the support structure, particularly for dismantling the heavy load and the components. In principle, however, it could also remain in the support structure, particularly if components need to be replaced or overhauled from time to time. The invention is sufficiently explained by the exemplary embodiments explained above. However, it could of course be explained by further variants.As a variant, the lifting system could be equipped with a different number of lifting units 50, 51 and longitudinal elements 34 than those shown, and the cross beams 46, 47 could be arranged differently than shown. Likewise, the supporting structure could be arranged, for example, in a building and be primarily composed of supporting pillars or similar.
[0041] Hoists, powered pulleys, climbing cranes, and / or similar devices could be used as lifting systems. Instead of an SPMT, another feed system, such as a vehicle sliding on a plastic or running on rails, or the like, could be used as the transport means 11.
