Description

P35926NL00/IWO
Title: SYSTEM COMPRISING A CRANE AND METHOD OF HOISTING
The invention relates to the field of cranes. For example, WO2009099319 discloses a vessel provided with a crane, wherein the crane comprises a revolving structure, a boom that is pivotally mounted to the revolving structure, and a luffing assembly configured for luffing of the boom. The crane further comprises a hoist assembly with one or more hoist winches, one or more hoist cables driven by the one or more hoist winches, and a hoist block suspended from the one or more winch driven hoist cables of the hoist assembly. The hoist block has multiple cable sheaves and is provided with a crane hook assembly, in the example of figure 6 with two ramshorn hooks that are connected via a common and freely swivelling carrier to the hoist block.
The hoist assembly of a vessel mounted crane may be provided with heave compensation to allow for compensation of heave motion, e.g. by embodying the hoist winch as an AHC winch or by means of one or more heave compensating cylinders and one or more associated cable sheaves acting on a section of the hoist cable.
Generally, for example in WO2009099319 and in many existing cranes, the crane hook assembly is permanently fitted on the hoist block, at least in a manner that is not attractive in view of exchanging the crane hook assembly for another crane hook assembly. If the crane is to be used for hoisting different loads, commonly use is made of wire slings between the crane hook and the object, e.g. with an intermediate spreader or the like.
Arrangements are known that allow for easier coupling and decoupling of a tool to the hoist block of the crane, for example the tool being a crane hook. WO2020/055249 discloses such a system, commercially available and known as Universal Quick Connector.
It is an object of the invention to provide at least an alternative system.
This is achieved according to a first aspect of the invention by a system comprising a crane and an exchangeable tool, e.g. for supporting a load, e.g. for use on a vessel, said exchangeable tool comprising, at an upper side thereof, a lower tool connector, wherein the crane comprises: - a hoist assembly, comprising: o one or more hoist winches ;
co one or more hoist cables, driven by the one or more hoist winches ; - atool suspension device, comprising: o an elongated hoist block, both ends thereof being suspended from the one or more hoist cables of the hoist assembly, the hoist block comprising one or more fixed support elements, e.g. one or more recesses and/or inward protrusions, o an upper tool connector, configured to releasably engage on the lower tool connector of the exchangeable tool, so as to suspend the tool from the upper tool connector, the fixed support elements supporting the upper tool connector and being configured to absorb the load of the suspended tool and optionally the load supported by the tool, wherein the tool is pivotable relative to the hoist block about a horizontal roll pivot axis (A) perpendicular to the hoist block; wherein one or more dampers are provided between the hoist block and the tool to dampen and/ or control pivot movement of the tool relative to the hoist block about the horizontal roll pivot axis.
Dampening and/ or control of the pivot movement of the tool, optionally with a load about the roll pivot axis is in particular advantageous when there is a risk that wind gets hold of the tool orthe load, such as when the load supported by the tool is a wind turbine rotor blade, and the tool comprises a yoke for receiving the blade.
The dimensions of wind turbines have steadily increased over the recent years, mainly in view of economical efficient energy generation. As a result, wind turbines having a capacity over 10 MW, e.g. 14 MW or recently 15 MW are now commercially available. These wind turbines have very large rotor blades, e.g. over 75m, or even over 100m in length. For example, each blade of the newly proposed Vestas 15 V236 turbine measures 115.5 meters in length. The Siemens Gamesa’s SG 14-222 DD direct drive turbine has a blade of 108 meters in length. This market development further increases demands on the installation of a rotor blade to an offshore wind turbine. The mass of a single blade may be well in excess of 50 tons.
In particular for elongated tools/ loads extending essentially parallel to the elongated hoist block, the inventive provision of dampers between the hoist block and the tool attribute to improved hoisting operations.
In the inventive system, the tool is pivotable relative to the hoist block about a horizontal roll pivot axis perpendicular to the hoist block. This pivot movement is e.g. present in embodiments wherein the fixed support elements are configured to pivotally support the upper tool connector about the horizontal roll pivot support axis. Alternatively, it is conceivable that there is a pivot connection between the lower tool connector and the exchangeable tool, or that the lower tool connector is articulated and defines a horizontal roll pivot axis.
In the inventive system, the elongated hoist block acts as a spreader. Because of the elongated construction of which the ends are suspended from the hoist cables, the hoist block itself cannot pivot about the horizontal roll pivot axis, in particular not because of its weight, and the weight of the connected tool, e.g. with a blade being suspended therefrom.
The dampers are provided between the hoist block and the tool. Because the hoist block cannot pivot about the horizontal roll pivot axis, the damper is able to dissipate pivot energy from the tool/ load.
Advantageously, dampers are provided at opposite ends of the hoist block.
The dampers or shock absorbers is a mechanical or hydraulic device designed to absorb and damp shock impulses. It does this by converting the kinetic energy of the shock into another form of energy (typically heat) which is then dissipated. Most shock absorbers are a form of dashpot (a damper which resists motion via viscous friction). For example, pneumatic and hydraulic cylinders (shock absorbers) are used in conjunction with cushions/ bellows and springs.
In embodiments, one end of the damper is mounted to the hoist block, while the other end engages the tool directly or indirectly.
The damper can be passive or actively controlled by control means. Advantageously, the damper is adjustable, e.g. the spring stiffness can be adjusted, and/or the damper is preloaded.
In addition, control means are applied to position the tool (with a load), e.g. to align a wind turbine rotor blade with a wind turbine nacelle.
In embodiments, the upper tool connector is configured to allow for swivelling of the tool, if engaged, about a vertical axis. Preferably, the upper tool connector comprises a rotational drive configured to selectively drive said swivelling of the tool. Advantageously, the dampers slidably engage the tool directly or indirectly to allow rotation of the tool.
In embodiments, the damper comprises a tubular component. The tubular component is e.g. a hydraulic or pneumatic cylinder, an upper end of which is fixed to the hoist block and a lower end engaging the tool directly or indirectly.
In embodiments, an auxiliary arm is provided, to which the lower end is hingedly connected.
The auxiliary arm is further hingedly connected to the hoist block to allow operation of the damper. The auxiliary arm comprising a horizontally extending tool engaging surface to engage the tool. Preferably the tool engaging surface presses against the tool, optionally via sliding pads or the like on the auxiliary arm, to allow swivelling of the tool (and optionally the load supported by the tool} about the vertical axis.
In embodiments, the tool is pivotable relative to the hoist block about a horizontal pitch pivot axis parallel to the hoist block. This movement is blocked by the tool engaging surface of the auxiliary arm.
By actively controlling the damper, also the auxiliary frame is controlled. This makes it possible to switch from a tool that is pivotable about a horizontal roll and? or pitch axis with respect to the hoist block to a tool of which the position is controlled relative to the hoist block, seen in a horizontal plane. (Controlled) Rotatation of the tool is still possible due to the tool engaging surface of the auxiliary arm.
In embodiments, a tagline system is provided for controlling the tool, and optionally the load supported by the tool, that is lifted by the crane, e.g. a wind turbine component, e.g. a wind turbine rotor blade in horizontal orientation. The tagline system comprises: . a guide assembly with a guide extending along the boom, ° a tagline assembly, comprising: o atagline, o a tagline winch for the tagline, co a tagline trolley that is mounted on the guide for travel along the guide.
Advantageously, the tagline is connected to the hoist block. This is possible because due to the controlled movement of the tool, the tool and the hoist block mechanically act as a unit.
This enables the exchange of tools without having to disconnect and reconnect the tagline.
The tagline system may operate in a horizontal plane to position the tool, and e.g. prevent rotation. Taglines extend essentially horizontally. In addition or instead thereof, taglines can extend vertically and thus also attribute to position the tool, and contribute to dampening a pivot movement of the tool about a horizontal roll pivot axis and/ or a horizontal pitch pivot axis.
In embodiments, the crane further comprises a revolving structure, a boom, pivotally mounted to the revolving structure and a luffing assembly configured for luffing of the boom. This is common configuration of a crane.
In embodiments, the upper tool connector comprises: - One or more mobile tool retainers, adapted to engage the lower tool connector of the exchangeable tool so as to suspend the tool from the upper tool connector underneath the tool suspension device, - an upper connector body supporting the one or more mobile tool retainers, the upper connector body being supported by the fixed support elements of the hoist block in a configuration wherein the fixed support elements are arranged below the mobile tool retainers of the upper tool connector, the fixed support elements being configured to support the upper tool connector body, and therewith the upper tool connector, and to absorb the load of the suspended tool, and any load supported by the tool, below the mobile tool retainers suspending the tool.
This tool connecter is described in more detail in W02020/055249 and commercially available and known as Universal Quick Connector. Other types of connectors are also conceivable.
A first aspect of the present invention also relates to a method of hoisting wherein use is made of the above described system, wherein during hoisting the tool (and optionally the load supported by the tool) the dampers dampen and/ or control pivot movement of the tool relative to the hoist block about the horizontal roll pivot axis.
In the art, cranes are known having a crane boom that is provided with a tagline system for controlling a tool (and optionally load supported by the tool) lifted by the crane, e.g. a wind turbine component, e.g. a wind turbine rotor blade that is lifted in a horizontal orientation.
An example of a crane is shown in EP 2 889 251. This document, e.g. in figure 1 thereof, discloses a crane with a crane boom having a length, which crane boom is provided with a tagline system for controlling a tool lifted by the crane, e.g. supporting a wind turbine component, e.g. a wind turbine rotor blade in horizontal orientation. The tagline system comprises a guide wire assembly with a guide wire extending along the boom, the guide wire having a lower end and an upper end. A tensioning winch is connected to the lower end of the guide wire and the upper end is secured to the crane boom at an anchoring point. The crane boom further has a tagline assembly, which comprises: - atagline, - a tagline winch for the tagline, - a tagline trolley that is mounted on the guide for travel along the guide.
A second aspect of the invention aims to provide improvements of the known system and operation thereof, in particular in view of behaviour of the tagline system when hoisting a tool with a significant load, e.g. to a significant height, e.g. when lifting a wind turbine rotor blade in horizontal orientation for fastening thereof to the hub of a (offshore) wind turbine.
This is achieved according to a second aspect of the invention by a system comprising a crane and an exchangeable tool, e.g. for supporting a load, e.g. for use on a vessel, said exchangeable tool comprising, at an upper side thereof, a lower tool connector, wherein the crane comprises: - arevolving structure, - a boom, pivotally mounted to the revolving structure, - aluffing assembly configured for luffing of the boom, - a hoist assembly, comprising: o one or more hoist winches, o One or more hoist cables, driven by the one or more hoist winches, - a tool suspension device, comprising: o an elongated hoist block, both ends thereof being suspended from the one or more hoist cables of the hoist assembly, the hoist block comprising one or more fixed support elements, e.g. one or more recesses and/or inward protrusions, o an upper tool connector, configured to releasably engage on the lower tool connector of the exchangeable tool, so as to suspend the tool from the upper tool connector, o the fixed support elements supporting the upper tool connector and being configured to absorb the load of the suspended tool and optionally the load supported by the tool, o wherein the tool is movable relative to the hoist block;
- atagline system for controlling the tool, and optionally the load supported by the tool, that is lifted by the crane, e.g. a wind turbine component, e.g. a wind turbine rotor blade in horizontal orientation, wherein the tagline system comprises: o a guide assembly with a guide extending along the boom, o atagline assembly, comprising: » ataglne, » a tagline winch for the tagline, » a tagline trolley that is mounted on the guide for travel along the guide, wherein movement of the tool relative to the hoist block is controlled (restricted, blocked) and in that the tagline is connected to the hoist block.
Movability of the tool relative to the hoist block is common and frequently desired for connection of the tool with the tool suspension device. In embodiments, one or more of the following movements are possible, after engagement of the tool with the tool suspension device:
A. Swivelling of the tool about a vertical axis; In embodiments, the upper tool connector is configured to allow for such swivelling, if engaged, about a vertical axis . Advantageously, the upper tool connector comprises a rotational drive configured to selectively drive said swivelling of the tool . Such a rotation drive can control or block any swivelling of the tool.
B. The tool is pivotable relative to the hoist block about a horizontal roll pivot axis perpendicular to the hoist block. In embodiments according to the first aspect of the invention, one or more dampers are provided between the hoist block and the tool to dampen and/ or control pivot movement of the tool relative to the hoist block about the horizontal roll pivot axis. Such dampers at least restrict such horizontal roll movement.
C. The tool is pivotable relative to the hoist block about a horizontal pitch pivot axis parallel to the hoist block. In embodiments, this movement is blocked by an auxiliary arm. In embodiments of the first aspect of the invention, the damper comprises a tubular component, an upper end of which is fixed to the hoist block and a lower end being hingedly connected to an auxiliary arm, the auxiliary arm being hingedly connected to the hoist block. This auxiliary arm advantageously comprises a horizontally extending tool engaging surface. This tool engaging surface is able to block such horizontal pitch movement. In embodiments, by actively controlling the damper, also the auxiliary frame is controlled. This makes it possible to switch from a tool that is pivotable about a horizontal roll and/ or pitch axis with respect to the hoist block to a tool of which the position is controlled relative to the hoist block, seen in a horizontal plane. (Controlled) Rotatation of the tool is still possible due to the tool engaging surface of the auxiliary arm.
Hence, controlling movement of the tool includes blocking of the movement, restricting movement and/ or being able to actively control the movement.
The effect of controlled movement is that the tool and the hoist block mechanically act as a unit. This is in particular advantageous for controlling the tool (and supported load) that is lifted by the crane via the tagline system.
Commonly, the tagline system engages the tool or the load. After installation of the load the tagline is disconnected, to be reconnected when hoisting another tool.
According to the second aspect of the invention, the tagline engages the hoist block. This is possible because due to the controlled movement of the tool, the tool and the hoist block mechanically act as a unit. This enables the exchange of tools without having to disconnect and reconnect the tagline.
In embodiments, the tagline assembly comprising two tagline trolleys, each guiding a tagline from a tagline winch to an end of the hoist block.
In embodiments, the guide assembly is a guide wire assembly and the guide is a guide wire, the guide wire having a lower end and an upper end, wherein a tensioning device, e.g. a tensioning winch, is connected to one of said lower end and upper end, and wherein the other of said lower and upper end is secured relative to the crane boom,
In alternative embodiments, the guide is a rail, e.g. connected to or formed integral with the boom.
The second aspect of the invention also relates to a method of hoisting wherein use is made of the above described system, comprising the steps of: - positioning the hoist block at a tool receiving position, e.g. at deck level, - connecting the tagline to the hoist block, - the upper tool connector engaging the lower tool connector;
- controlling the movement of the tool relative to the hoist block, e.g. by controlling a damper according to claim 1 and/ or an auxiliary arm according to claim 4 between the hoist block and the tool; - hoisting the tool, optionally with a load; - using the tagline system to position the hoist block and the connected tool and optionally the supported load in a horizontal plane at an elevated position of the tool suspension device.
The second aspect of the invention advantageously allows an operation wherein multiple tools, e.g. yokes with wind turbine blades are provided, e.g. on deck of a vessel, which can be hoisted one after each other by connecting and disconnecting the tool connectors without disconnecting the one or more taglines from the hoist block.
A third aspect of the invention aims to provide improvements in the operation of the known system, in particular in view of behaviour of the tagline system when hoisting a tool with a significant load, e.g. to a significant height, e.g. when lifting a wind turbine rotor blade in horizontal orientation for fastening thereof to the hub of a (offshore) wind turbine.
This is achieved according to a third aspect of the invention by a method of hoisting a load wherein use is made of a system comprising a crane and an exchangeable tool, e.g. for supporting a load, e.g. for use on a vessel, said exchangeable tool comprising, at an upper side thereof, a lower tool connector, wherein the crane comprises: - arevolving structure, - a boom, pivotally mounted to the revolving structure, - a luffing assembly configured for luffing of the boom, - a hoist assembly, comprising: o one or more hoist winches, o one or more hoist cables, driven by the one or more hoist winches, - atool suspension device, comprising: o a hoist block, suspended from the one or more hoist cables of the hoist assembly, the hoist block comprising one or more fixed support elements, e.g. one or more recesses and/or inward protrusions, o an upper tool connector, configured to releasably engage on the lower tool connector of the exchangeable tool, so as to suspend the tool from the upper tool connector,
co the fixed support elements supporting the upper tool connector and being configured to absorb the load of the suspended tool and optionally the load supported by the tool, - atagline system for controlling the tool, and optionally the load supported by the tool, that is lifted by the crane, e.g. a wind turbine component, e.g. a wind turbine rotor blade in horizontal orientation, wherein the tagline system comprises: o a guide assembly with a guide extending along the boom, o atagline assembly, comprising: » atagline, » a tagline winch for the tagline, » a tagline trolley that is mounted on the guide for travel along the guide, the method comprising the steps of: - positioning the hoist block at a load receiving position, e.g. at deck level, and positioning the tagline trolleys at an elevated position, - the upper tool connector engaging the lower tool connector, - hoisting the tool, optionally with a load; - using the tagline system to position the hoist block and the connected tool and optionally the supported load in a horizontal plane at an elevated position of the tool suspension device.
The advantage of positioning the tagline trolleys at an elevated position, e.g. raised all the way to the top, is that the tagline trolleys and taglines interfere less or not at all when a tool, optionally with a load, is picked up, e.g. from deck.
In embodiments, when the tool and optionally the load is at the desired height, the tagline trolleys are lowered to a level where the taglines run at the desired angle to control the tool (and load).
Advantageously the taglines run essentially parallel to the hoisting wires in the elevated position of the tagline trolleys.
As will also follow from the drawings it is foreseen that the aspects of the invention and embodiments thereof are combined.
