Abstract

Cable drum lifting and transport device comprising a cylindrical body 1, which has at one end a crane hook receiving device 2 and at the other end two eccentrically mounted rotatable outwardly expandable shaped bodies 4, wherein the two axes with the eccentrically mounted rotatable outwardly expandable shaped bodies are rotatably mounted on the upper part of the cylindrical body via a linkage, wherein each axis is under tension via a spring, so that the eccentrically mounted rotatable outwardly expandable shaped bodies are spread outwards for safety reasons in the rest state, wherein the springs could also be arranged so that the eccentrically mounted rotatable outwardly expandable shaped bodies are retracted.

Description

The invention relates to a cable drum lifting transport device.Cable reels generally have a reel core with two reel flanges and are used for receiving a winding material made of electrical cables. Cable reels are used in various sizes and reel diameters. The type, length and thus weight of the wound cable and thus the total weight of a completely or partially wound cable drum can also vary greatly. In cable manufacturers, logistics centers and production plants, this has the result that a large number of different cable drums must be transferred daily from a production site or a storage site to a distribution site or to a production site and, if appropriate, back again. Due to the usually high weight, the cable drums are gripped, transported and placed back at the destination, for example, by a forklift truck. For this purpose, the cable drums are laid down e.g. flat on the floor with the first drum flange. The lift truck then engages with the lifting fork the second drum flange. In this case, the lifting fork is moved apart to such an extent that it does not touch the cable wound onto the cable drum and only bears against the outer edge of the second drum flange, after which the cable drum can be lifted. These transport processes often damage the wound cable, since when lifting rods are carelessly used, the edge or the tip of the lifting fork can act with great force on the winding material. In addition, work is usually carried out under high time pressure, in particular in logistics centers, on account of large amounts of envelopes, for which reason incorrect manipulations occur regularly. After damage has occurred as a result of a mismanipulation, the relevant cable drum must be unwound and the damaged location on the cable cut out. The remains of the cable that cannot be used further must be disposed of. Damage is often detected even at the customer's first, after which the elimination of the defect on site is often also not possible at all and the supplied cable reel must be returned with correspondingly high costs. The risk of damage is particularly high when the cable drum is almost completely wound with cable. Cable reels can therefore only be wound up to about 80%, since otherwise the risk of damage caused by lifting forks increases, or the lifting forks can no longer be attached at all to the cable flange. Thus, about 20% of the recording capacity is lost at each drum.It is the object of the invention to improve the prior art and in particular to provide cable drum lifting transport device with which cable drums can be lifted and transported easily and reliably. The object is achieved by the features of the claims.The invention relates to a cable drum lifting transport device according to claim 1.The cable drum lifting transport device has a cylindrical body which is preferably constructed from solid metal, such as preferably steel, aluminum, and has at one end a crane hook receiving device which preferably forms an oval half-ring which is preferably circular only at the top and is otherwise preferably rectangular. At the other end of the cylindrical body, the cylindrical body has two eccentrically fastened rotatable, outwardly expandable shaped bodies, which are preferably two semicircular-shaped, circle segment-shaped, cylinder-shaped half-disks, which are preferably positively locking with the cylindrical body. The eccentrically attached rotatable outwardly expandable dies may have any shape as long as they are eccentrically attached rotatable dies that do not protrude beyond the cylindrical body when retracted. These may be rectangular plates, oval plates or rods.These eccentrically fastened rotatable outwardly expandable shaped bodies are rotatably fastened on a respective axle which is preferably guided through a respective bore in the cylindrical body. The two axles with the eccentrically fastened rotatable outwardly expandable molded bodies are preferably rotatably mounted on the upper part of the cylindrical body via a rod assembly, wherein each axle is preferably under tension via a spring, so that the eccentrically fastened rotatable outwardly expandable molded bodies are expanded outwardly in the idle state for safety reasons, wherein the springs could also be arranged such that the eccentrically fastened rotatable outwardly expandable molded bodies are retracted. The two axes are preferably arranged inside the cylindrical body parallel to the longitudinal axis of the cylinder. The two axles are rotatable via a rotating device, wherein these are preferably rotatable manually or preferably via a motor, such as a servomotor. The two axles are rotatably connected via a plate with two bores in each of which an axle is mounted, wherein a lever is preferably attached to an axle, which lever rotates the axles inward against the spring force by preferably a quarter revolution, so that the eccentrically attached rotatable, outwardly expandable molded bodies retract and move outward by releasing the lever. The plate is connected at one end preferably via a central bore to one axle and at the other end the plate preferably has an eccentric bore via which the plate is connected to the other axle, the eccentrically arranged bore, in addition to the other axle, also having the lever attached to it, which rotates the two axles via the plate.The two axles can also preferably each be rotated, preferably manually, via a gearwheel which is arranged in each case around its circumference, with a drive axle which is arranged between the two axles, wherein the drive axle likewise has a gearwheel which engages in a positive-locking manner in the two gearwheels of the two axles. This embodiment could also be driven by means of a servomotor on the drive axle.The cable drum lifting transport device according to the invention preferably has a ring as stop, which has a larger diameter than the cylindrical body and is arranged between crane hook receiving device and eccentrically fastened rotatable, outwardly expandable shaped bodies.The cable drum lifting transport device according to the invention preferably has a sensor, such as preferably a light barrier, on the eccentrically fastened rotatable outwardly expandable molded bodies for detecting that a body is being lifted.FIGS. FiguresFIG. 1 shows the cable drum lifting transport device according to the invention in a side view. In the middle of the cylindrical body 1, which shows a U-shaped crane hook receiving device 2 from the front at the top, and has a ring as a stop 3 at the middle thereof, and the extended two eccentrically fastened rotatable, outwardly expandable shaped bodies 4 at the bottom. At the top of the cylindrical body 1 there can be seen the spring 8 and the lever 5 which can actuate the two axles 7 via a plate 6, only one axle 7 being visible, while the other axle is covered by this axle 7 and is shown in broken lines since it is located inside the cylindrical body 1.
