Description

[0001] The invention relates to a load securing device for drum goods according to the features of the preamble of claim 1.

[0002] In practice, such load securing devices are used, for example, to secure cable drums to the loading platform of a transport vehicle. Alternatively, such load securing devices can also be used to store cable drums on a flat surface.

[0003] CN 2 08 471 281 U describes a load securing device for cable drums, comprising four clamping blocks. These clamping blocks engage with a grid on the loading platform on their underside and are secured to the platform via this grid. The cable drums are bolted to the clamping blocks to secure them. This load securing device requires a specially prepared loading platform and is only suitable for certain standard sizes of cable drums.

[0004] FR 675 784 A describes a securing device for drums, which has opposing blocks whose distance from each other can be adjusted via locking rods or by means of lockable perforated rods. Standard dimensions are also specified for this load securing device, making it difficult to secure cable drums that deviate from the standard dimensions.

[0005] From DE 414 974 A, a load securing device for drums is known. This device has four blocks that can be placed on a surface. Two of the blocks are attached to a square iron bar. The distance between the square iron bars, and thus the distance between the blocks, can be adjusted by means of tension chains.

[0006] DE 17 45 190 U shows wheel chocks for securing vehicles. The wheel chocks are placed on a surface and act in conjunction with a vehicle wheel in the manner of a wheel wedge.

[0007] The invention aims to provide a load securing device and a method for securing drum goods that is simple to implement in terms of design and easy to use. In particular, it should be possible to reliably secure even heavy drums. Furthermore, it should be possible to secure drums of different sizes reliably and stably.

[0008] This problem is solved according to the invention by a load securing device for drum goods with the features of claim 1.

[0009] Furthermore, this problem is solved by a method for securing drumware according to the features of claim 10 according to the invention.

[0010] According to the invention, a load securing device for drum goods, in particular for cable drums, is proposed, comprising four wedges that can be placed on a loading surface and two crossbeams, wherein two of the wedges are attached parallel to and spaced apart from each other to a crossbeam with an adjustable distance between them. Essentially, two clamping devices, each with a turnbuckle, are provided between the two crossbeams to allow stepless adjustment of the longitudinal distance between the crossbeams.

[0011] One advantage is that the adjustable attachment of the wedges to the crossbeams and the continuously adjustable clamping devices allow the load securing device to be used for drum goods of varying dimensions. In particular, the load securing device can be continuously adjusted to the specific size of the drum goods, thus offering a universal range of applications.

[0012] A further advantage is the robust design of the load securing device according to the invention. The load securing device is preferably suitable for securing drum goods weighing more than 5 t, and in particular also drum goods weighing more than 10 t. The maximum weight of the drum goods to be secured is limited only by the loading capacity of the transport vehicle used and can, for example, be 20 t or 30 t.

[0013] The term "drum goods" preferably refers to goods that are wound onto a drum. Examples include cable drums, hose drums, or similar items.

[0014] Preferably, the term "loading area" refers to a flat loading surface used for transport or storage. The loading area can be, for example, the loading platform of a vehicle, in particular the flatbed of a truck or van, or a stationary loading area in a hall or outdoors.

[0015] Preferably, the term "tensioning device" refers to a means for adjusting and tensioning. For example, chains or straps fall under the term "tensioning device." Chains can be made of steel or a robust plastic, such as Dyneema. Steel components are used for the wedges. The wedges can be made, for example, of steel profiles and / or semi-finished steel products.

[0016] Preferably, the term "transverse direction" is understood to mean the lateral direction that is parallel to the axis of the drum to be transported. In particular, the term "transverse direction" is understood to mean the direction in which the crossbeams run. In particular, the term "longitudinal direction" is understood to mean a direction perpendicular to the transverse direction. Preferably, the crossbeams run parallel to each other in the transverse direction and are spaced apart from each other in the longitudinal direction.

[0017] Furthermore, the inventive concept also includes a method for securing drum goods comprising the following steps: - Providing a load securing device according to one of the preceding claims, - Positioning the load securing device on a loading platform, - Adjusting the lateral spacing of the wedges on the crossbeams in accordance with the drum material to be secured, - Placing a drum on the wedges

[0018] The essential point is that the longitudinal distance of the wedges is adjusted by means of the clamping devices in such a way that the drum or the drum material is raised by a certain distance from the loading surface, with the predetermined distance being in the range of 20 mm to 60 mm.

[0019] By adjusting the clamping devices and lifting the drum from the loading platform, a particularly reliable and robust securing of the drummed goods is achieved. This ensures that the drum rests securely on the four wedges, preventing the drum from being levered off the wedges due to vibrations during transport. Furthermore, wear on the drum is reduced because it is not in contact with the loading platform.

[0020] To ensure the safe transport of the drummed goods, it is preferably recommended that the drummed goods be secured to the loading platform using securing straps. This creates an additional securing point that prevents the drummed goods from moving on the loading platform.

[0021] In a preferred embodiment, the tensioning devices may each comprise a chain or strap and a turnbuckle, in particular a ratchet tensioner with a folding lever. A tensile force can be applied to the chain or strap via the turnbuckle and maintained permanently. The turnbuckle may, for example, comprise two opposing threads, with a tensile force being generated by turning a nut. Advantageously, the nut can be equipped with a folding lever, allowing the nut to be easily turned manually by unfolding the lever to apply the tensile force to the tensioning devices. This allows the load to be easily secured manually via the folding lever. Once the tensile force has been applied, the turnbuckle can be locked by folding the lever, thus ensuring that the applied tensile force remains permanently in place.

[0022] A ratchet tensioner can also be used, which uses a ratchet mechanism to prevent the nut from rotating in the upright position, i.e., in the direction of decreasing tension. This ensures particularly reliable securing of the applied tension of the turnbuckle. To open the turnbuckle, the ratchet can be disengaged via a release mechanism, allowing the tension to be released by turning the nut back.

[0023] Preferably, at least one of the clamping devices can be attached to both crossbeams and / or to two wedges opposing each other longitudinally, or to one wedge and one wedge. Due to the robust design of the load securing device, the clamping devices can engage both the crossbeams and, alternatively, the wedges to apply the necessary clamping force.

[0024] In particular, it may be provided that the crossbeams and / or the wedges have eyelets for attaching the clamping devices.

[0025] To secure the drummed goods, especially the cable drums, the wedges each have an open U-profile on their upper side. The drums of the drummed goods can be inserted into the open U-profile. The vertically extending legs of the U-profile limit the drum's lateral movement.

[0026] In particular, it can be provided that the U-profile is asymmetrically designed, or that several, preferably all, U-profiles are asymmetrically designed, such that the outer leg of each U-profile is higher than the inner leg. In practice, it has been shown that during transport of the drum material, for example when cornering, the pressure on the outer legs is higher, and load securing can be improved by making the outer leg of each U-profile higher than the inner leg.

[0027] For example, it may be provided that the outer leg of one of the U-profiles has a height in the range between 50 mm and 120 mm, in particular in the range between 65 mm and 100 mm, and that the inner leg has a height in the range between 5 mm and 20 mm.

[0028] A simple and robust design of the load securing device can be achieved by preferably providing that the wedges are made of steel and have a closed and / or smooth underside, preferably that the top of the wedges is closed.

[0029] In a preferred embodiment, the crossbeams may have spaced-apart holes in which the wedges can be fastened by means of bolts, in particular by means of dowel pins and spring pins, or by means of screws. This allows the position of the wedges to be easily adjusted in the transverse direction. For example, the holes can be provided at a predetermined distance in the crossbeams. Preferably, the distance between the holes in the crossbeams is less than or equal to the width of the bearing surface of the wedges, so that a seamless adjustment to different widths of the drum material is possible by laterally adjusting the wedges.

[0030] In a preferred embodiment, it can be provided that both crossbeams, or that one of the crossbeams, has two transversely extending cross-sections with rectangular and / or oval cross-sections, wherein the cross-sections are arranged rotated relative to each other, in particular rotated by 90° relative to each other. In particular, the cross-sections can be arranged such that the longer extension of one cross-section is horizontal and the longer extension of the other cross-section is vertical. This allows for a particularly stable design, since the cross-sections are arranged rotated relative to each other, and thus, depending on the moment acting on the crossbeams, the corresponding cross-section can absorb this moment without causing significant twisting of the crossbeam.

[0031] One application of the load securing device according to the invention is the transport of drummed goods, such as cable drums with electrically conductive cables or fiber optic cables. The load securing device can be sold as a commodity or rented as an accessory.

[0032] The figures show further exemplary embodiments of the invention, which are described below. These include: Fig. 1: A schematic view of the load securing device with a drum of goods; Fig. 2: a schematic 3D representation of the load securing device according to the invention without a drum; Fig. 3a and Fig. 3b an enlargement of the front wedges of the load securing device; Fig. 4 A schematic side view of the load securing device 1 in transport setting

[0033] The figures show exemplary embodiments of the load securing device according to the invention. These are not to be understood as limiting. Features with equivalent effects are designated with the same reference symbols. It is clear to the person skilled in the art that, within the scope of protection defined by the claims, they can combine or easily modify the features shown in the figures without departing from the scope of the invention.

[0034] The Fig. 1 and Fig. Figure 2 shows an embodiment of the load securing device 1 according to the invention. Fig. Figure 1 shows the load securing device 1 with a stylized cable drum 11. In the Fig. Figure 2 shows the load securing device alone, i.e. without the cable drum.

[0035] The load securing device has four wedges: the first wedge 41, the second wedge 42, the third wedge 43, and the fourth part 44. Two of the wedges are shown in the illustration of the Fig. 2. Wedges 41 and 43, as well as wedges 42 and 44, are each attached to a crossbeam 21 or 22, respectively. Several holes 23 are arranged on each of the crossbeams 21 or 22 to allow the wedges 41, 42, 43, 44 to be adjusted in their position on the respective crossbeam. The several holes 23 form a grid of holes with regular spacing. The wedges 41, 42, 43, 44 can be secured in the holes 23 by means of locking pins or spring clips 24, or released from the holes 23 and moved on the respective crossbeam 21 or 22, and then secured again in a new position by inserting the locking pin or spring clip 24.

[0036] Each of the crossbeams 21 and 22 has two cross sections. Crossbeam 21 comprises cross sections 211 and 212, and crossbeam 22 comprises cross sections 221 and 222. The two cross sections of a crossbeam are arranged rotated 90° relative to each other. Cross section 212 of the first crossbeam 21 and cross section 222 of the second crossbeam 22 are arranged vertically. Cross section 211 of the first crossbeam 21 and cross section 221 of the second crossbeam 22 are arranged horizontally. The respective cross sections of a crossbeam 21 and 22 are additionally connected to each other by means of struts. This results in better force absorption by the load securing device 1.

[0037] The wedges 41, 42, 43, and 44 have a flat and smooth underside. The upper surface is designed as an inclined plane. The upper surface is designed as a flat plane and inclined in such a way that it can tangentially rest against the circumference of the cable drum 11 to be secured. On the upper surface, the wedges 41, 42, 43, and 44 each have an upwardly open U-profile 411, 421, 431, and 441, respectively. The legs of the U-profiles 411, 421, 431, and 441 point upwards and laterally encompass the cable drum 11 to be secured. The legs of the U-profiles 411, 421, 431, and 441 can be designed asymmetrically such that the outer leg is longer than the inner leg. This secures the cable drum 11 against lateral slippage.

[0038] The distance between the two crossbeams 21 and 22 is adjusted to the drum material 11 being transported and is regulated by means of clamping devices 31 and 32, respectively. Each clamping device 31 and 32 has a chain 311 and 321, respectively, which is connected to a clamping device 312 and 322, respectively. A tensile force can be exerted on the chain 311 and 321, respectively, via the clamping devices 312 and 322, thereby adjusting the distance between the two crossbeams 21 and 22.

[0039] The Fig. 3a and Fig. Figure 3b shows a detailed enlargement of the front pair of wedges 41 and 42. Each of the wedges 41 and 42 has an eyelet 412 and 422, respectively, for receiving the clamping device 31. The corresponding features shown in the Fig. 3a and Fig. 3b wedges 43 and 44 (not shown) provide a corresponding eyelet for the second clamping device 32. The chain 311 of the clamping device 31 is connected to the first turnbuckle 312. The turnbuckle 312 comprises a nut connected to a folding lever 314 and two opposing threads 313. The nut can be turned via the first folding lever 314 to vary the effective length of the turnbuckle 312. This allows a permanent tensile force to be applied to the chain 311 to adjust the distance between the two crossbeams 21 and 22.

[0040] The second clamping device 32 is constructed analogously and has a second chain 321 with a second turnbuckle 322 and a second folding lever 324 with nut and corresponding thread, as in the Fig. 2 is shown.

[0041] The Fig.Figure 4 schematically shows the adjustment of the clamping devices 31 and 32 for transporting a drum item 11, e.g. a cable drum 11. For this purpose, the tension of the clamping devices 31 and 32 is adjusted so that the drum 11 lifts off the loading surface 12.

[0042] The distance between the two crossbeams 21 and 22 is adjusted by placing a cable drum 11 on top of the four wedges 41, 42, 43, and 44 to secure it. A tensile force is then applied to the clamping devices 31 and 32, respectively, via the turnbuckles 312 and 322, such that the cable drum 11 lifts off the loading platform 12 by a specific distance X.

[0043] The pulling force is applied until the cable drum 11 is raised by a distance X in the range of 20 mm to 60 mm. This causes the cable drum to rest only on the four wedges 41, 42, 43 and 44 and to no longer have direct contact with the loading platform 12.

[0044] After lifting the cable drum 11 to be secured, it is further secured against the loading platform 12 by means of tension straps, so that the secured load remains stationary on the loading platform 12 and cannot slip during transport.
