- US 4,204,664 shows a crane with a
- the present invention has for its object to provide a rope storage device for a crane rope, which is not directly formed by the rope drive device itself, so that additional degrees of freedom in the design of the rope drive device and the
- Rope storage device can be created.
- Retractable can be inserted by a cable drive device and from which the crane cable when discharging through the
- Cable drive device can be removed, comprising an outer support structure and a rotatably drivable inner body arranged therein, the inner body being rotatably drivable about an essentially vertical axis of rotation in operation and comprising a bottom which can be rotated with it and onto which the crane cable is attached Insert is placed, and one
- the crane rope is therefore removed from the rope force for pulling in and for
- Crane rope is executed separately.
- the crane rope is placed in a number of turns around the inner body. It proves to be advantageous that the crane cable is no longer subjected to high tensile loads, but can even be deposited essentially free of draft, which proves to be gentle on the material and reduce wear.
- the crane cable When the crane cable is pulled in by the cable drive device, it is preferably fed to the cable storage device essentially without tension, in which case it is then
- Feed tube is provided to feed the crane rope to the rotatingly drivable inner body.
- the cable guide device is designed to be able to move back and forth so that a radial storage position of the crane cable on the bottom of the inner body or on previously laid windings can be specified.
- the cable guide device can then between a radially inner and a radially outer region of the
- Inner body are moved back and forth so that a screw or spiral winding of the crane rope, in particular in several layers one above the other, can be made or dissolved.
- the rotatably drivable inner body is surrounded radially on the outside by elements which are designed or arranged concentrically to its axis of rotation and which delimit a receiving space for the crane cable radially on the outside.
- these elements could be formed by rods which are arranged around the inner body in the manner of a cage. The crane cable could then bear against these elements from the inside or be supported from the radially outside.
- the rotatably drivable inner body is surrounded radially on the outside by a wall extending concentrically to its axis of rotation, in particular made of rolled sheet metal or sheet steel or of plastic, which delimits a receiving space for the crane cable radially on the outside.
- Rope storage device are arranged in a fixed position or that the elements or the wall are constructed so as to be fixed against rotation with the rotatingly drivable inner body together with its bottom.
- Rope storage device serves to support or support the crane rope. There are big ones in themselves
- the inner body extends in the direction of rotation
- Mandrel or drum body in particular made of rolled steel sheet or a tubular body. This mandrel or drum body then forms a kind of
- the bottom of the inner body can be designed in the form of a circular disk or in the form of an annular disk.
- the inner body is supported by a bearing device, in particular a self-aligning bearing, in particular a self-aligning ball bearing, so that the inner body can carry out slight oscillating movements in the range up to 2 °, preferably up to 1 ° to the vertical or to an initial direction .
- a bearing device in particular a self-aligning bearing, in particular a self-aligning ball bearing, so that the inner body can carry out slight oscillating movements in the range up to 2 °, preferably up to 1 ° to the vertical or to an initial direction .
- the rotation drive device for the inner body is designed in terms of control technology in such a way that the rotation drive of the inner body in
- Rope storage device can be supported specifically and in particular synchronously, by processing the input variables mentioned.
- Such an input variable can be, for example, the drive speed of the cable drive device or this variable
- the rotation drive device for the inner body is designed in terms of control technology in such a way that the
- the crane rope is deposited in the form of a screw or spiral.
- This in turn implies that the circumferential length of the turns decreases from turn to turn when winding from outside to radially inside, or increases from turn to turn during winding from radially inside to radially outside. Due to the above further inventive idea that the rotary drive by means of a speed control does this during prolonged retraction or output adapted to the crane rope, a targeted intended placement of the crane rope turn-to-turn can be realized and supported in any case.
- the rotation drive device for the inner body is designed in terms of control technology in such a way that periodic and preferably continuous
- the speed control is then preferably sinusoidal.
- the present invention also relates to a crane with a cable drive device for the crane cable
- Traction winch drive device is, which is preferably designed as a separate assembly from the cable storage device and arranged on the crane. In this case, if the crane rope is fed to the rope storage device essentially free of tension and load by means of the traction winch drive device, the crane rope only needs to be fed to the rope storage device from above when it is pulled in by the rope drive device and then lies down in the rotating inner body with the aid of gravity. Protection is also claimed for a method for
- FIG. 1 is a schematic representation of the rope storage device according to the invention in connection with a
- Figure 2 is a perspective view of a
- Rope storage device for arrangement on a crane
- Figure 3 is a perspective view of the
- FIG. 4 is a perspective view of the inner body
- FIG. 5 shows a perspective view of the inner body with a surrounding wall for delimiting a receiving space for the crane rope;
- Figure 6 is a schematic representation of a known
- Figure 6 illustrates schematically a previously known
- Cable storage device in which a crane cable is wound onto a drum body of a cable winch as a cable drive device or is unwound again from the latter.
- FIG. 1 schematically illustrates one
- Rope storage device for a crane rope 4 in connection with an example rope drive device 8 designed as a traction winch drive 6 in a crane (not shown in more detail).
- Rope storage device 2 is shown in more detail in Figures 2 to 5. It comprises a support structure 10, which is, for example, a welded structure or a riveted or glued structure
- Support structure 10 is used to hold and arrange the components of the described below
- Rope storage device for forming an assembly.
- the supporting structure it would also be conceivable for the supporting structure to be formed by elements which can be assigned to the crane, but this is less preferred.
- the support structure 10 accommodates the actual functional elements of the cable storage device 2. This is a rotatably drivable inner body 18, around which the crane cable 4 is laid in a plurality of turns in a manner to be described in more detail.
- Inner body 18 comprises a mandrel 22 which extends in a direction of rotation 20 and is cylindrical, for example
- a base 26 which is also preferably made of metal and in the case shown by way of example
- the floor 26 forms a type of turntable on which the crane cable can be placed or should be placed in a plurality of turns, preferably helical or spiral. At the bottom 26 of the
- Inner body 18, a fastening device 27 is provided for one end of the crane cable 4.
- the inner body 18 comprises at its upper end a circular cover plate 28 which delimits an annular gap 30 for the crane cable 4 radially on the inside.
- the radially outer boundary of this gap 30 is formed by an outer element 32 in the form of a cylindrical wall 34 which is formed and arranged concentrically to the axis of rotation 20.
- This element 32 which extends concentrically to the axis of rotation 20, or the wall 34 is formed, for example, from rolled steel sheet and, in the case illustrated by way of example, is arranged in a stationary manner with or in relation to the supporting structure 10. But it would be too it is conceivable that this element 32 is designed to rotate with the inner body 18, which can also bring advantages. However, then access to that
- the inner body 18 comprises an upward at its upper end
- a cable guide device 38 can be provided, as shown, for example in the form of a feed tube for the crane cable 4.
- FIG. 3 shows one with the inner body 18 and the wall 34 surrounding the inner body 18 omitted
- support structure 10 is in the area of the drive coupling between the inner body 18 and
- Rotation drive device 40 a self-aligning ball bearing 46 or another bearing device with play for the inner body 18 is provided.
- Rope storage device 2 an electronic
- the electronic control device 50 is designed such that the rotation drive of the inner body 18 can be controlled in terms of speed depending on input variables, in particular on variables made available by the cable transport device 6. If the rope over the example shown
- Traction winch drive 6 is drawn in and is fed from above through the cable guide device through the gap 30 to the inner body 18, it proves to be advantageous if the speed of the inner body 18 is matched to the length of the crane cable 4 fed per time. However, a more extensive control or speed control when pulling in or discharging the crane cable from the cable storage device 2 can prove to be advantageous. If the crane rope, for example when pulling in, advantageously in a plane or position next to each other and preferably in
