Description

P35894NL00
CRANE HAVING A CRANE BOOM PROVIDED WITH A TAGLINE SYSTEM
The present invention relates to the field of cranes having a luffing crane boom that is provided with a tagline system.
Generally, the tagline system is provided to allow enhanced control of the position and/or orientation of the load during the hoisting process.
In particular in the field of installation and/or maintenance of wind turbines, e.g. offshore, the need exists for handling of components "at the height of the nacelle", which includes, for example, the handling of the rotor blades during their installation to the hub of the wind turbine. Current designs propose or already have the nacelle at a height of more than 100 meters, e.g. at 120 meters or more, for example the Haliade-X 12 MW wind turbine.
Cranes with tagline systems are frequently employed to control the position and/or orientation of a wind turbine component, e.g. the rotor blade. This is, for example, not done only during the hoisting of the rotor blade but also, or just, during the mounting of the root end of the blade to the hub of the wind turbine.
Examples of cranes having a boom provided with a tagline system are presented in
EP1925582, EP2490975, EP2889251, and DE20201003269U.
Ina commonly known design of cranes, the crane comprises: - a base structure, e.g. adapted to be mounted on a vessel, e.g. for fixation to the hull of the vessel; - a revolving structure slewable on a slew bearing about a vertical slew axis relative to the base structure, the structure being provided with a boom connection member, - a boom having a longitudinal axis, wherein the boom has an inner end connected to boom connection member, so that the boom is pivotal up and down about a boom pivot axis which is perpendicular to the longitudinal axis of a boom;
- a luffing device for pivoting the boom up and down, comprising a luffing winch and a variable length luffing system, - a hoist assembly comprising a winch and a winch driven cable, which winch driven hoist cable passes over a sheave assembly on the boom to a load suspension device so as to hoist a load suspended from the hoist cable and the load suspension device, e.g. a wind turbine component, wherein the boom comprises a boom leg, e.g. a single boom leg, embodied as a latticed hollow box structure, e.g. a rectangular cross section latticed hollow box structure, comprising a pair of front main chords at a front side of the boom leg, a pair of rear main chords at a rear side of the boom leg, the main chords being interconnected by lacing members between adjacent main chords.
The present invention aims to integrate a tagline system in optimal manner into a crane boom, e.g. in view of stability of the tagline system and/or in view of production of the crane boom, and maintenance costs, etc.
The present invention provides a crane according to claim 1.
In the inventive crane at least one of the front main chords of the boom leg is formed from four steel planar plate members that are welded to one another in a rectangular or square cross-sectional arrangement, wherein the four plate members are: - a front plate member; - arear plate member opposite the front plate member - an inner plate member, - an outer plate member opposite the inner plate member, wherein the front plate member extends from a corner joint with the outer plate member inward beyond a joint of the front plate member to the inner plate member, to form an inwardly protruding guide rail portion having an inner end face, wherein the outer plate member extends from the corner joint with the front plate member rearward beyond a joint of the outer plate member to the rear plate member to form a rearwardly protruding guide rail portion having a rear end face,
wherein the tagline trolley is provided with a first roller set of one or more rollers engaging the inner end face of the inwardly protruding guide rail portion and with a second roller set of one or more roller engaging the rear end face of the rearwardly protruding guide rail portion.
This design of the main chord of the crane boom leg optimally integrates a rail assembly for a tagline trolley with the main chord.
The crane may have a single boom leg, but in other embodiments the crane may have two boom legs, for example in a A-frame arrangement or in a H-frame arrangement. In embodiments, each boom leg has one or more tagline trolleys thereon in the manner as described herein. So, possibly, one crane boom has four tagline trolleys.
In a practical embodiment, the tagline trolley is further provided with a third roller set of one or more rollers engaging a front face of the front plate member, perpendicular to the first roller set, and the tagline trolley is provided with a fourth roller set of one or more rollers engaging an outer face of the outer plate member, perpendicular to the second roller set.
For example, at least the front plate member and the outer plate member have a thickness of at least 15 millimeters, e.g. about 20 - 30 millimeters.
In an embodiment, each of the front main chords of the boom leg is formed from four steel planar plate members that are welded to one another in a rectangular or square cross- sectional arrangement, wherein the four plate members are: - a front plate member; - arear plate member opposite the front plate member - an inner plate member, - an outer plate member opposite the inner plate member, wherein the front plate member extends from a corner joint with the outer plate member inward beyond a joint of the front plate member to the inner plate member, to form an inwardly protruding guide rail portion having an inner end face, wherein the outer plate member extends from the corner joint with the front plate member rearward beyond a joint of the outer plate member to the rear plate member to form a rearwardly protruding guide rail portion having a rear end face,
wherein as respective tagline trolley is associated with a respective front main chord, each tagline trolley being provided with a first roller set of one or more rollers engaging the inner end face of the inwardly protruding guide rail portion of the respective front main chord and with a second roller set of one or more roller engaging the rear end face of the rearwardly protruding guide rail portion of the respective front main chord.
In a practical embodiment, each of the tagline trolleys is further provided with a third roller set of one or more rollers engaging a front face of the front plate member, perpendicular to the first roller set, and each tagline trolley is further provided with a fourth roller set of one or more rollers engaging an outer face of the outer plate member, perpendicular to the second roller set.
In an embodiment, the crane boom has over at least a section of its length two boom legs, each having two main chords at a front side of the boom leg, wherein at least one of said front chords is embodied according to the invention, possibly both front main chords.
When the boom legs are parallel to one another, as in a H-frame crane boom, the rail portions may extend to proximity of the tip of the boom over these chords. The boom can also have an A-frame boom design, wherein the two boom legs are angled to one another.
Again, herein one or both main chords at the front side of each boom leg may be embodied according to the invention. In a lambda-design of the crane boom, wherein the boom continues at the apex of the two boom legs with a single distal boom section, e.g. as shown in WO2018/208158, main chords of the boom legs and/or of the distal boom section may be embodied according to the invention.
Itis envisaged, for example, that one pair of taglines is used when performing a lift operation to control the load primarily in a horizontal plane, e.g. to control rotation of the load about a hoist cable from which the load is suspended. In embodiments, another pair of taglines is primarily used for control of the load in a vertical plane, e.g. to control orientation of the load about a horizontal axis. The provision of four tagline systems, each having its own rail assembly on a respective front main chord, allows to use the two pairs for control of the load in horizontal plane and vertical plane, respectively.
In embodiments, the tagline system further comprises a tagline trolley drive assembly for each tagline trolley, e.g. for each tagline trolley independently, which drive is assembly is configured to provide controlled displacement of the tagline trolley along the boom leg. For example, the tagline trolley drive assembly comprises a tagline trolley drive winch and associated cable to provide controlled displacement of the tagline trolley along the boom leg.
In another embodiment, the tagline trolley drive is absent, and the trolley passively follows the motion of the load and/or load suspension device during hoisting.
In embodiments, the load suspension device is embodied as a blade lifting tool for installation of a rotor blade to a wind turbine. Various embodiments of such blade lifting tools are known in the art.
The present invention also relates to a crane boom provided with a tagline system configured for mounting in a crane as described herein.
The present invention also relates to a vessel provided with a crane as described herein, e.g. wherein the load suspension device is embodied as a blade lifting tool for installation of a rotor blade to a wind turbine.
The present invention also relates to a method for installation of a rotor blade to a wind turbine, e.g. an offshore wind turbine, wherein use is made of a crane as described herein.
The present invention will now be elucidated with reference to the drawings. In the drawings: - fig. 1 shows schematically a vessel equipped with a crane according to the invention, - fig. 2 shows a portion of the crane boom of figure 1 provided with a tagline trolley, - fig. 3 shows a close-up of the figure 2 with main front chord of the crane boom in cross- section and the tagline trolley travelling thereon, - fig. 4 shows the close-up of figure 3 from a different angle, - fig. 5 shows a portion of the crane boom of figure 1 provided with the tagline trolley from a different angle.
Figure 1 schematically shows an offshore vessel 1 with hull 2, a deck 3, and a crane 10.
In this example, the vessel 1 is a jack-up vessel having jack-up legs 4 that can be extended and retracted by an associated jack-up mechanism 5. The vessel, in other embodiments, could also be of an entirely different design, e.g. a floating monohull vessel, a semi- submersible vessel, a catamaran-type vessel, etc.
It is noted that the inventive concept is equally applicable to land-based cranes having a latticed crane boom, e.g. for use in wind turbine installation. For example, the crane has a road-vehicle type wheeled base, a base with crawler tracks, a base with track engaging wheels, or a base that is assembled in situ where the wind turbine is to be assembled.
The crane 10, in this example, is embodied as a so-called around-the-leg crane 10. Here it is schematically illustrated that a leg extends through a pedestal 11 of the crane 10.
The pedestal 11 is mounted to, or formed integral with, the hull 2 of the vessel 1.
The crane 10 further comprises a revolving structure 12 which is supported on the pedestal 11 via slew bearing 13 for rotation of the structure 12 relative to the pedestal 11 about a vertical slew axis.
The revolving structure 12 comprises a boom connection member 15.
The crane 10 has a boom 20 with a longitudinal axis 21.
For example, the boom 20 has a length of at least 60 meters between an inner end 22 and a tip end 23 of the boom 20. The length may in practical embodiments exceed 100 meters, e.g. about 150 meters.
The inner end 22 is pivotally connected to the boom connection member 15 so that the boom is pivotable up and down about a horizontal boom pivot axis 24 which is perpendicular to 20 the longitudinal axis 21 of the boom.
It is shown here that the vessel is equipped with a boom rest 60, on which the boom 20 can rest in a horizontal rest position, for example as is shown in figure 1.
A luffing device for the boom 20 is provided for pivoting the boom 20 about the horizontal boom pivot axis 24. This luffing device comprising one or more boom luffing winches 45 and variable length luffing system with one or more luffing cables 46 driven by the one or more luffing winches 45.
The crane 10 has a hoist assembly with one or more main hoist winches 70 and one or more main hoist cables 71 driven by the one or more main hoist winches 70. Here the hoist winches 70 are shown on the revolving structure 12, but they could also be arranged elsewhere, e.g. on the crane boom 20, e.g. close to the inner end thereof.
Other arrangements of the one or more winches are also possible, e.g. when the crane 20 is embodied as a mast crane and the one or more hoist winches are located inside a pedestal of the crane, e.g. on a revolving platform as is known in the art.
The one or more cables 71 pass over a sheave assembly 72 near the tip of the boom 20 to a load suspension device 75, also referred to as main hoist block. For example, a so-called blade lifting tool can be suspended from the main hoist block 75 to handle a wind turbine rotor blade by means of the crane 10.
In the illustrated example, the boom 20 has a single boom leg that is embodied as a latticed hollow box structure, here a rectangular cross section latticed hollow box structure, e.g. as shown in figures 2 - 5. The latticed hollow box structure of the crane boom 20 is essentially a welded steel structure of rigid design.
The latticed hollow box structure comprises a pair of front main chords 31, 32, at a front side of the boom leg, a pair of rear main chords 33, 34 at a rear side of the boom leg, the main chords 31,32,33,34 being interconnected by lacing members 35, 36, 37, 38 between adjacent main chords. The lacing members 35, 36, 37, 38 generally define with the main chords 31,32, 33, 34 latticed hollow box. It is noted that other lacing members, e.g. within the hollow box, may also be present, e.g. as illustrated in figure 2 with one or more diagonal lacing members in a plane transverse to the boom length.
The crane 10 is provided with a tagline system configured to control motion of the load connector and/or the load, e.g. a wind turbine component, e.g. a rotor blade, that is hoisted.
It is noted that the tagline system clearly may also be of use during lowering of the load connector and/or load, the term hoisting encompassing both hoisting and lowering.
The tagline system comprises a tagline trolley 80 that is movable along the boom leg in longitudinal direction of the boom leg. Furthermore a tagline winch 81 and a winch driven tagline 82 are present, which tagline — in use of the crane 10 — extends from the tagline trolley 80 to the load and/or to the load suspension device 75.
Here, as an example, the tagline trolley 80 has a chassis 83 that is configured to be guided on and travel over a respective front main chord 31 with multiple roller sets of one or more rollers as will be explained in the example below.
The chassis 83 supports one or more tagline sheaves 84 over which the tagline 82 passes.
The one or more sheaves 84 may be arranged to revolve about an axis that is of fixed orientation relative to the chassis 83, as shown, but pivotal arrangements of the one or more tagline sheaves 84 are also contemplated. For example, the one or more sheaves 84 being pivotal relative to the chassis 83 about an axis parallel to the front main chord.
In other designs of the tagline system in the context of the invention, the tagline is connected at an end thereof the trolley 80, e.g. with a tagline winch being provided on the load connector 75, and/or on a lifting tool, e.g. on a rotor blade lifting tool, and/or on the load. Of the tagline 82 passes from an end on the trolley to a sheave on the on the load connector 75, and/or on a lifting tool, e.g. on a rotor blade lifting tool, and/or on the load, and then back to a sheave on the trolley.
Preferably, the tagline system further comprises a tagline trolley drive assembly for each tagline trolley 80, e.g. for each tagline trolley on the crane boom 20 independently, which drive is assembly is configured to provide controlled displacement of the tagline trolley along the boom leg. For example, as known in the art, the tagline trolley drive assembly comprises a tagline trolley drive winch and associated cable to provide controlled displacement of the tagline trolley along the boom leg.
In the example, each of the front main chords 31, 32 of the boom leg is formed from four steel planar plate members that are welded to one another in a rectangular or square cross- sectional arrangement. This will be discussed herein with reference to front main chord 31, the other front main chord 32 being of the same design.
Herein, the term front refers to the side of the crane boom 20 where the hoisting is done by means of the hoist assembly, so where the load connector 75 and the suspended load are present during a hoist job for which the tagline system may provide enhanced control of the load connector and/or the load to be hoisted.
The four steel planar plate members that make up the hollow front main chord 31 are: - a front plate member 314; - a rear plate member 31c opposite the front plate member, - an inner plate member 31d, and - an outer plate member 31b opposite the inner plate member.
These plate members are welded together to form the rectangular or square cross-sectional design of the front main chord 31.
The front plate member 31a extends from a welded corner joint with the outer plate member 31b inward beyond a welded joint of the front plate member 31a to the inner plate member 31d to form an inwardly protruding guide rail portion 31e having an inner end face 31a1.
The outer plate member 31b extends from the welded corner joint with the front plate member 31a rearward beyond a welded joint of the outer plate member 31b to the rear plate member 31c to form a rearwardly protruding guide rail portion 31f having a rear end face 31b1.
The tagline trolley 80 is provided with a first roller set 93 of one or more rollers, preferably multiple rollers, engaging the inner end face 3141 of the inwardly protruding guide rail portion 31e.
The tagline trolley 80 is provided with second roller set 94 of one or more rollers, preferably multiple rollers, engaging the rear end face 31b1 of the rearwardly protruding guide rail portion 31f.
The tagline trolley is further provided with a third roller set 95 of one or more rollers, preferably multiple rollers, engaging a front face of the front plate member 31a, perpendicular to the first roller set 93,
The tagline trolley is provided with a fourth roller set 96 of one or more rollers, preferably multiple rollers, engaging an outer face of the outer plate member 31b, perpendicular to the second roller set 94.
As illustrated, it is preferred for the third roller set 95 and the fourth roller set 96 to engage on the front main chord 31 in proximity to the end face 31a1, 31b1 of the respective plate member.
The lacing members between the front main chords 31, 32 as well as between each front main chord 31, 32 and the nearest rear main chord 33, 34 are offset from the protruding portions of the front plate member and the outer plate member so as to allow for passage of the trolley, in particular for passage of the first and second roller sets 93, 94 of the trolley.
In an alternative embodiment, the second and/or third set(s) of rollers 95, 96 are absent.
Instead, for example, the first and/or second set of rollers are equipped with grooved rollers that engage on the end face 31a1 or 31b1 to have guided support not only in the plane of the respective front plate member or outer plate member as shown here, but also perpendicular tothe plane of the respective plate member. For example, the end face 31a1 or 31b1 can be beveled to have a V-shape, and the rollers having a corresponding shape.
The figures also illustrated the optional provision of one or more hook members 85a, b on the chassis 83 of the trolley 80, that engage behind the protruding section of the respective front plate member 31a or outer plate member 31b.
These hook members 85a, 85b may serve to safeguard the mounting of the trolley 80 on the front main chord.
