    The present invention relates to a device for controlling flexible lines, hose cable or the like, in the case of a crane-carrying work tool according to the preamble of claim 1. The invention also relates to a method of using a hose of so-called high pressure type according to patent claim 13.
    Crane-borne hydraulically driven work tools, for example harvester heads, are usually gimbal-mounted in the tip of a crane arm with a link device, pivotable in two perpendicular horizontal pivot axes and rotatable about their own axis by means of a single rotator. A crane arm of this type is normally vehicle-borne and arranged to turn in a horizontal plane accompanying a driver's cab of the vehicle. By own axis is meant in the following the vertical vertical work tool can be oriented by pivoting. axis of rotation which is usually or oriented and around which For communication with the work unit which includes hydraulic flow and electricity / data are wires in the form of hose and electrical conductors for electricity / data usually located on the outside of the arm parts and form protruding loops or lyres of sufficient length. to partly allow the crane's included arm parts to swing and move relative to each other, partly to allow the work tool to turn and perform work. The hydraulic flow usually includes two or three communication channels comprising inflow from pump to consumer directional valve P, return flow from consumer to tank via valve R, and in any fall return flow directly from consumer to tank T.
    Hose of high pressure type, so-called hydraulic hose usually has an inner reinforcement, which limits both bending and rotation of the hose between its ends. Communication of hydraulic flow from the crane tip to the said rotator and any other consumer work tool therefore takes place with the help of swivels, ie. rotary bushings that prevent hoses from being twisted or torn off when turning or turning the work tool. Swivels that allow electricity / data or signal communication also occur. A swivel comprises a fixed part and a movable part rotatably mounted thereto and is usually used for rotatably transmitting electricity / data or combinations thereof both optically and electrically. The most common task of the swivel, however, is to transfer flows of some medium, for example liquid. Electric swivels, so-called electric swivels that can withstand up to Q poles occur.
    A trend in technology is that more and more units for control and connection of hydraulic functions in work tools are connected electrically via network cable and local networks or buses so-called CAN buses (Controller Area Network) for digital data communication middle nodes, control units and a central computer included in a vehicle. By node is meant end or switching points for data traffic and by control unit is meant sensors or actuators for position control of, for example, hydraulic valves. It is also essential that the required httpwdmszacco.com/siies/se/casen4766830/41601s52/P41601552SEO0/P41601552SE00__2016-06-16__160616 besk o patentkrav.docx 1G 3G data communication can take place between the crane tip and the control unit cage units included. It should be understood that currently existing ice swivels with reciprocating conductor paths which transmit data via electrical contact are not normally suitable for use in the transmission of accurate measurement or positioning data. The slightest play or error in the power transmission, for example a directional valve when performing a maneuvering movement, can have fatal consequences.
    As part of reducing the need for complicated swivel solutions, it has proved expedient to place, as far as possible, sensors and actuators for position control, for example control and regulating equipment, hydraulic valves, etc. on a rotatable lower part of rotator blades in close connection with a working tool. holder.
    When working with the crane, the above-mentioned free loops with hose placed on the outside of the arm parts can get stuck in different types of obstacles, tree branches or the like and be damaged. In order to reduce these problems, attempts have been made to arrange the hose centrally and protected as far as possible both inside the crane arm and in the linkage in which the work tool is suspended from the crown tip. For an example of this, reference can be made to WO 03057ö15 At which shows how to use a combination of so-called "Open joints" in the link device between the nose portion and the rotator of the work tool, as well as a strategic location and "orientation" of the swivel connection nipples to the center and the top of a swivel in the middle of the rotator. Thanks to the open joints with coaxial bearings at a distance from each other and the central location of the connection wrenches around the pivot axis, it has been possible to pull free hydraulic hoses in a protected manner inside the link device between the crane arm nose and the tool rotator where the hydraulic hoses to the rotator connections pass. lVloderna work tools are equipped with a variety of hydraulically driven consumers, motors and the like that require large amounts of new hydraulic flow. In the case of the volume flows in question, it is extremely difficult to arrange the hose centrally inside the suspension device between the crane tip and the work tool with the required flow area and at the same time ensure that the hose can be pulled, bent and rotated during the turning tools of the work tool. Due to the limited space, people have so far been instructed to use free-hanging lyre slings. Depending on the volume flow, it is of course desirable to arrange both communication of hydraulic medium and electrical and data between the crane tip to a crane-borne work tool in as discreet and as protected a manner as possible.
    A first object of the present invention is therefore to provide in a simple manner a device which makes it possible in a discreet and well-protected manner to bend pipes, hose and cable for both hydraulic flow and electricity and data between the nose portion of the crane arm and a hydraulically driven in the nose portion. suspended work tools. A second purpose is to allow data communication to be carried out accurately and securely in a secure and secure manner.
    It is here desired to provide a device which offers measuring and positioning data to be transmitted with such accuracy that sensors, actuators for position control, for example control and regulating equipment, hydraulic valves, etc. can be placed on a rotatable lower part of the rotator or on a holder included in the work tool. Furthermore, it is a desire to reduce the number of swivels and to avoid complicated swivel solutions when transferring both hydraulic medium and egg and data accurate measurement or positioning data.
    In order to be able to transmit the required volume of hydraulic flow, it is desirable to arrange the hose inside the link device to run in a cup-shaped curve as a soft and compliant center of the link device's both perpendicular horizontal pivot axes intermediate crankshaft to connect to the rotator coaxially with the tool. This first object of the invention is solved by a hose guide device which exhibits the features and characteristics set forth in claim i.
    The second object of the invention is solved by using a hose of the so-called high-pressure type, i.e. a hydraulic hose to form a hose package according to claim 13. The insight underlying the invention is that significant flows can be transmitted in a link device on longitudinal sections of flexible hydraulic lines (hydraulic hose) offering improved possibilities to rotate, to bend transversely to its longitudinal axis. The combination to arrange a swivel device in the crane arm nose and to use the so-called "Open joints", and arranging a bushing in the center of the rotator can significantly improve the operating space. Electrical data communication cables, which are generally very sensitive to external influences, are hereby offered improved opportunity to be arranged without the need for complicated swivel solutions to transmit electrical and in particular interference. measurement and positioning data.
    In an embodiment of the invention, the rotator comprises a bushing which allows communication of hydraulic flow and electricity and data to pass through the center of the rotator, between an upper part and a lower part thereof, conduits (hose) running in a single-shaped curve between first and second pouring means in crane tip respectively in a central tower of rotation.Thanks to "open joints" the wires can cut through the center of the deflector both horizontal pivot axes to via the bushing and one-way valve located on the underside of the rotator, on a holder communicate with a rotary motor included in the rotator.
    The bushing allows hydraulic flow as well as electricity and data to be communicated through the center of the rotator coaxially with the work tool's own pivot axis. The bushing makes it possible to transfer hydraulic flow as well as electricity and data to and from an area below hitpv / dmszacco.comfsries / sa / casen irvssssc / rir sot 552 / P41 ö fi t 552SEOÛ / P4t 601 552SEOÜ__20'i ö-Oö-'i ö ___ t 60616 patent o 4 of the rotator, on a rotatable lower part of the rotator or in connection therewith. This makes it possible to place control and regulating equipment, hydraulic valves, etc. on the work tool whereby the need for uncomplicated swivel solutions can be reduced.
    Thanks to the rotation of the rotator which is located centrally or regionally around the first axis A and the fact that the lines run coaxially with the axis direction of the work tool, the distance between the connection points between the respective ends of each line and the intermediate crane and rotator can be extended. This creates additional business people for the lines used for communication. Improved mobility in Serri As a result, longer and coarser flow cables with flow capacity can be used. By offering each line an improved transverse direction, the force moments that occur during turning and maneuvering the implement at the crane end can be reduced. Both hydraulic lines and lines for electricity and data will be bent in a gentler way with wider (larger) radii of curvature compared to what would have been the case. the wires would be forced to bend with narrower (smaller) bend radii. The following is an exemplary embodiment of the invention with reference to the accompanying drawings, in which: a view shows a perspective view of a device according to the present invention showing a part of a hollow crane arm, a crane arm nose, and a gimbal driven hydraulic tool via a link device.
