Description

Title: Rolvlonder

The invention relates to a roller deck, provided with an upper side for supporting a vertically erected roller in operating condition, with a plastic upper deck with a plastic supporting structure located under the upper deck and connected to the upper deck, which supporting structure has at least two on either side of the roller deck comprises elongated frame parts.

Such roll platforms are known from practice and are used in the transport of steel rolls. Usually a roller deck of this type is made of wood and provided with a flat wooden top deck on which a roller of steel can be placed upright.

Such a deck is also known from US 5 868 080 / the deck shown herein is made of plastic and has frame parts which lie on the surface of the deck and provide a non-slip surface.

A drawback of the known roller decking is that these are often damaged during transport, as a result of which damage can be caused to the roller placed on the roller decking and the handling process is disrupted. Re-use of an already used roller deck is rarely possible. It is also a disadvantage that when moving the wooden roller decks, wood splinters become detached from the decks very quickly. Such contamination of the environment by wood splinters can be undesirable or even dangerous.

The object of the invention is to overcome these drawbacks by providing a rolling platform which is strong enough to support a roll of steel, can withstand the handling process and can be used several times.

To this end, the invention provides a roller deck of the type indicated above, characterized in that the upper deck is provided near recesses with recesses which at least partly reveal the frame parts.

Because the roller deck according to the invention is provided with a support structure reinforced with frame parts that supports a plastic upper deck, a roller deck is obtained which is light, strong and durable, in particular because lifting loops engage with the deck during lifting of the deck. exposed frame parts and therefore do not cause wear to the deck.

The roller deck according to the invention can advantageously consist of two uniform parts, whereby it is achieved that the mold costs for manufacturing the roller deck are considerably reduced.

The invention will be further elucidated on the basis of a detailed description of an exemplary embodiment of the invention with reference to the drawing.

Herein: fig. 1 shows a perspective view from above of a roller deck according to the invention, fig. 2 shows a perspective view from below of a roller deck according to the invention, fig. 3 shows in perspective a top view of another roller deck according to the invention, fig. 4 is a perspective view of a part of the roller deck from FIG. 3, and FIG. 5 is a perspective view of a roller deck according to the invention in operating condition.

In Figs. 1 and 2, an example of an embodiment of a roller deck 1 according to the invention is shown. The roller deck 1 has an upper deck 2 which is substantially square in plan view. The surface of the deck deck 2 is substantially flat to support an axial end of a roll of steel in operating condition. The upper deck 2 is provided with a number of openings 10 to 9 which reduce the weight of the roller deck 1 without negatively affecting the strength of the roller deck 1. In a central part of the upper deck 2, an engaging bobbin 3 is located which protrudes above the plane of the upper deck 2. The 1014120 * 3 gripping spool 3 is provided with a protruding gripping edge 23, situated along a part of the peripheral edge of the gripping spool 3.

On a first side 4 of the roller deck 1, the top deck 2 is provided on the underside with a central side part 5. On the opposite side 24 of the roller deck 1, a second central side part 25 is located, which is designed in accordance with the side part 5. The description of the side part 5 therefore applies mutatis mutandis also to the side part 25. The side part 5 extends from the top deck 2 downwards, and extends in a longitudinal direction over a central part of the side 4 of the top deck 2.

The bottom 6 of the side part 5 facing away from the upper deck 2 is substantially flat, so that the side part 5 forms a foot 15 for the upper deck 2. The side part 5 is provided with a continuous, round opening 7, an axial axis of which extends at a distance from and parallel to the upper deck 2.

The corners of the side 4 of the roller deck 1 are each provided on the underside of the upper deck 2 with respective headers 8 and 38. The headers 8 and 38 are of the same shape but mutually mirrored. The head piece 8 is provided with a continuous opening 9 which is in line with the opening 7 of the side part 5. The head piece 8 is connected to the side part 5 by means of an intermediate piece 40, the intermediate piece 40 being the line of the openings 7 and 9. In a manner similar to the head piece 8, the head piece 38 is provided with a continuous opening 39 which is in line with the opening 7 of the side part 5. The head piece 38 is connected to the side part 30 by an intermediate piece 50, the intermediate piece 50 being the line of openings 7 and 9.

A round tube 30 is placed in the continuous openings 9, 7 and 39 of the roller deck 1. The tube 30 is fixed in the openings 9, 7, 39 by fixation means, for instance in the form of fixation bolts (not shown). The tube 30 can for instance be made of steel. The A ^ ^) \ J i Λ '' Γ "% · 4 tube 30 considerably strengthens the roller deck 1, so that roller deck 1 can withstand high loads. The invention is not limited to the metal embodiment of the elongated frame part 30 mentioned here. The invention can also be applied from other materials, such as reinforced or non-reinforced plastics and composites with which a sufficient reinforcement of the roller deck 1 can be obtained. The invention is also not limited to the round cross-section of the construction shown in the exemplary embodiment. elongated frame part, for example, the elongated frame part can also be designed with a different cross-sectional shape, such as for instance an oval, a rectangle with or without rounded corners, and I-shaped.

In top view, the upper deck 2 is provided with respective recesses 41, 51 on an edge portion of the side 4 at the level of the intermediate pieces 40, 50. These recesses 41, 51 extend so far from the edge of the upper deck 2 that the tube 30 is released. The recesses 41, 51 can receive a hoisting loop in operation, the hoisting loop resting on the exposed parts of the tube 30.

The side part 5 is provided with a recess 55 in a central part near the bottom 6. This recess 55 extends over the full depth of the side part 25 and is rounded outwards by means of a rounding 56. The recess 55 in operation can receive a tensioning strap, which is used for fixing a roller placed on the roller deck 1.

In this example, the side part 5 is partly hollow 30 by recesses 58, 59 which are arranged on either side of the recess 55 in a direction transverse to the upper deck 2. By making the side part 5 hollow, a reduction in the weight of the roller deck 1 obtained without affecting the strength of the roller deck 1.

The side part 5 is connected on the side remote from the upper deck 2 to a bottom deck 60, which is substantially flat on the underside facing outward. In a central part of the bottom deck 60, an opening 20 is provided which is so large that if two roller floats 1 are stacked, the engaging block 3 of the bottom deck is received by the opening 20 so that the bottom deck of the top deck on the upper deck of the lower deck rest. This achieves that roller platforms 10 1 can be stacked in a compact manner. The under deck 60 is further provided with a number of openings 81 to 84, whereby the weight of the rolling deck 1 is limited without negatively affecting the strength of the rolling deck 1.

A centerline of the roller deck is located between and parallel to the side parts 5 and 25. Either side of this centerline are two connecting parts 71, 72. The connecting part 71 is located near the center line on the side of the side part 5 and extends from the edge of the roller deck 1 parallel to the center line towards the center of the roller deck 1 to substantially at the level of the bobbin 3 The connecting part 71 also extends from the bottom deck 60 to the top deck 2. The connecting part 72 is located near the center line on the side of the side part 25 and extends from the edge of the roller deck 1 parallel to the center line towards the center of the roller deck 1 to substantially at the height of the engagement bobbin 3. The connecting part 71 also extends from the bottom deck 60 to the top deck 2.

Connecting parts 73, 74 are correspondingly located on the opposite side of the roller deck 1. The connecting part 74 here is in line with the connecting part 71 and the connecting part 73 is in line 35 with the connecting part 72. The connecting parts 71 to 74 are aligned in such a way that the connecting parts 71 to 101412 Ο "" 6 74 with the upper deck 2 and the lower deck 60 define a tunnel 75 which extends in a central part of the deck 1 between the upper deck 2 and the lower deck 60 parallel to the two side parts 5, 25. This tunnel-shaped structure 75 creates a light and strong connection obtained between the upper deck 2 and lower deck 60, whereby the strength of the roller deck 1 is considerably increased with only a slight increase in weight. In addition, it is possible to pass a tensioning strap through the tunnel 75 to fix a roller placed on the roller deck 1 in operating condition.

As already described above, the side part 25 is designed in the same manner as the side part 5. In Figs. 2 and 3, for brevity, the headers 8 ', 38', the recesses 41 ', 51', 55 ', and the tube 30' are indicated.

In the example described, the roller deck 1 is made in one piece in that, except for the metal frame parts 30, 30 ', the roller deck 1 is made of contiguous plastic. This has the advantage that the manufacture of the roller deck 1 can take place in a simple manner, for instance by manufacturing the roller deck 1 in a mold and then installing the metal frame parts 30, 30 '.

In use, an empty roller deck 1 is lifted by means of a crane with a gripper, the gripper 25 starting from the edge 23 of the gripping bobbin 3. The edge 23 hereby gives an improved grip for the gripper. The roller deck 1 is then moved to a desired position and set down.

Fig. 5 shows a roller deck according to the invention, on which a roll of steel R is placed on the upper deck of the roller deck 1. The central opening of the roller hereby falls over the gripping bobbin 3. The roller placed on the roller deck 1 is fixed on the roller deck by two crotch straps, of which the first crotch strap 110 via the 35 passages 55, 55 'in the side parts 5 and 25 of the roller deck 1 runs over the roller R and the second crotch strap 120 101412 0-7 runs through the tunnel 75 over the roller R, transversely to the first crotch strap 110. Both crotch straps 110, 120 are tightened and secured with tensioning means (not shown) so that the roll R is firmly connected to platform 1.

5 Two lifting loops are used to lift a deck with a roller placed on it. The first lifting loop 130 is introduced into the lifting openings 41, 41 'on one side of the roller deck 1, the lifting loop 130 resting on the exposed parts of the tube 30, 30'.

The second lifting loop 140 is correspondingly arranged in the lifting openings 51, 51 'on the opposite side of the roller deck 1, the lifting loop 140 resting on the exposed parts of the tube 30, 30'. The roller deck 1 with roller R can be lifted and moved with the hoisting loops 130, 140 thus arranged. It is advantageous here that the lifting loops 130, 140 only engage on the tubes 30, 30 ', as a result of which wear of the roller deck 1 does not occur due to possible sanding of the lifting loops. The lifting loops are thereby properly enclosed in the lifting openings 41, 20 41 ', 51, 51' and cannot slide. Because the tubes 30, 30 'absorb the lifting forces and distribute them over the entire roller deck 1 via the side parts 5, 25 and via the tunnel structure 75, it is achieved that the roller deck does not collapse during use.

A forklift truck can also be used to move the roller deck with the roller placed on it. The fork of the forklift truck is placed between the top deck and the bottom deck, with the fork legs on either side of tunnel 75.

Because the roller deck according to the invention is manufactured from plastic with metal frame parts, the chance that particles of the roller deck become detached during use is greatly reduced. As a result, the roller deck according to the invention can also be used in environments where the prevention of contamination by foreign particles must be avoided.

In Figs. 3 and 4, an embodiment of a roller deck according to the invention is shown. The roller deck 100 shown in operating mode as shown in Fig. 3 is completely identical to the roller deck 1 as described above. However, the roller deck 100 comprises two parts, namely a first part 200 and a second part 300, which, in the assembled state as shown in Fig. 3, are provided with metal frame parts 250, 350. Both parts 200, 300 are identical. Essentially, the embodiment of the roller deck 10 as shown in the first exemplary embodiment is divided into two equal halves in a direction transverse to the metal frame parts. The ends of the half side parts 5 ', 25' of part 200 thus released are provided with respective coupling elements 230, 240. The coupling elements 230, 15 240 are designed in such a way that these coupling elements can engage on shaped coupling elements of an equal deck part. Correspondingly, the now halved engaging bobbin 3 'of two coupling elements 210, 220, which are also designed, is such that these coupling elements can engage on shaped coupling elements of an equal plank part. This allows the two identical parts 200, 300 to be coupled to form a roller deck 100. Then, the metal pipes 250, 350 or other shaped frame parts can be introduced into the openings 25 provided for this purpose and attached to the parts 200, 300. Hereby a strong roller deck 100 is obtained.

The parts 200, 300 are each made in one piece from plastic. Preferably, the plastic used for this is wholly or partly recycled plastic.

Because the two halves 200, 300 are of the same shape, it is achieved that the same mold can be used for manufacturing both halves. This reduces manufacturing costs. Incidentally, the invention is not limited to one or two-part roller deck; the invention also provides for the use of multi-part roller decking.
