ES2267954T3 - SET OF LIQUID RETENTION THAT INCLUDES A CUBA AND A LOAD PLATFORM. - Google Patents

Abstract

The pallet (20) forms part of an assembly with a holder (4) attached to its underside. The holder has a number of cavities (12) to receive any liquids spilled from containers (6) being handled, with the positions of the cavities corresponding to the positions of the pallet's feet. The holder also has side walls (16) that extend over the sides of the pallet and have lugs (32) to hold them in place. The pallet has ribs (30) between upper and lower surfaces forming channels for handling vehicle forks, and apertures (28) for liquids to pass through.

Description

Liquid retention assembly comprising a tank and a loading platform.

The present invention relates to a set of liquid retention, intended in particular to allow transport containers containing a liquid susceptible to spill.

Different sets are already known that allow Perform this function. In particular, the document US-A-5 020 667 describes a set, of the "pallet container" type, comprising a tank retention, which forms an open receptacle, particularly strong. Said retention tank has hollow feet and some housings arranged between the hollow feet, said housings bounded at the top by a support plane which form the feet stand out. The support plane is intended for rest on a fork inserted between the feet for the maintenance of said set. The retention tank also presents a flange at the top of which rests a plane, and more precisely a trellis, intended to support in particular some barrels The assembly also comprises a removable tubular support which extends substantially between a central foot and the lattice.

However, this set is relatively Onerous and heavy.

The invention aims to reduce the cost of said set, while facilitating the transport of containers For this, the invention proposes that:

-

saying plane is integrated in a loading platform (pallet) that It also includes feet that form a surface overhang lower of said plane,

-

the feet of the holding tank and the feet of the loading platform are arranged in correspondence, so that the feet of the loading platform are inserted inside the feet of the Cuba and are supported on the basis of the feet of the Cuba,

-

the feet of the holding tank and the feet of the loading platform form noticeably at the same height, respectively with respect to the support plane and the plane, such that the lower surface of the loading platform is noticeably leaning against the support plane of the retention tank.

Thus, the structural strength of the whole It consists of the loading platform. It supports the containers on its plane, rests on the ground by means of its different feet or on a fork by means of its plane. By consequently, the essential part of the efforts is directly Supported by the loading platform. Not having the tank then to bear more than the weight of the liquid that has been poured into it, and may constitute a simple less resistant envelope by both less expensive and less heavy. In addition, the deformations of the set are reduced, which also facilitates transport.

Advantageously, the feet of the platform load are inserted inside the essential part at least of the feet of the holding tank, and preferably in the inside each of the feet of the retention tank.

The efforts supported by the platform Cargo are thus better distributed. According to an advantageous feature, The invention further proposes that the flange of the holding tank extends beyond the upper surface of the plane.

Thus, the plane may be arranged closer to the points of application of the efforts on the fork and on the ground, while increasing retention capacity from Cuba

In order to increase the resistance of the loading platform, the invention also proposes that the platform of load present some ribs that extend between its upper surface and its lower surface.

In order to improve the robustness of the loading platform, the invention proposes that some at least of the feet of the loading platform comprise a plurality of pivots

In addition, the invention proposes that the feet and / or the flange of the holding tank present a profile wavy, which improves its rigidity.

The invention will appear even more clearly in the description that follows, given with reference to the attached plans, in which:

- Figure 1 is a schematic view in exploded perspective of a set according to the invention,

- Figure 2 is a middle section view of the assembly of figure 1.

Figures 1 and 2 illustrate a set 1 that comprises a structured loading platform (pallet) 2, particularly rigid and a retention tank 4 that surrounds the loading platform 2.

The loading platform 2 essentially comprises a plane 20 and a few feet 22. Plane 20 has a surface upper 20a and a lower surface 20b. It comprises a plate 26 crossed by wide openings 28 that extend according to the upper surface 20a and intersecting ribs 30 that are extend vertically between the upper surface 20a and the bottom surface 20b. Plate 26 is substantially flat and supports a few bodies 6 (one has only been represented). The plane 20 it also comprises a peripheral rib 36 which extends slightly upwards with respect to the upper surface 20a. The feet 22 are hollow and also have openings 28. The plate 26, the ribs 30, the peripheral rib 26 and the feet 22 they form a monobloc piece obtained directly from material.

The holding tank 4 forms a receptacle for liquid. It comprises, from the same material, a support plane 10 substantially horizontal, a few hollow feet 12 in the part bottom and lateral sides that are substantially vertical they form a flange 16 at the top.

The feet 12 have at their lower end a noticeably flat base 14 resting on the floor 8, while that the flange 16 extends beyond the upper surface 20a of the plane and presents at its upper end a step that forms a peripheral stiffening belt 18. The steps performed between the 12 feet allow to receive a forklift fork which will raise the assembly by means of the support plane 10.

The feet 22 of the loading platform 2 are each arranged in correspondence with one of the feet 12 of the holding tank 4, so that they are inserted inside each of the 12 feet. They have, at their lower end, a base 24 that comes into contact with base 14 of feet 12.

The height H_ {22} of the feet 22, said of another mode the distance between the base 24 and the bottom surface 20b of the plane 20 is very slightly higher, substantially equal, to the height H_ {12} of feet 12, in other words the distance the base 14 and the support plane 10 enter. The bottom surface 20b of plane 20 is therefore substantially in contact with the support plane 10.

The holding tank 4 is substantially less rigid and robust than the loading platform 2 on which it is held by means of spikes 32 that form protrusion over the flange 16 of the tank 4 and that are butt over the rib peripheral 36 of the loading platform.

On the other hand, the feet 22 of the tank are constituted by a plurality of pivots 38, advantageously two, four or six juxtaposed pivots.

As illustrated in Figure 2, the tank of retention 4, in particular the feet 12 and the flange 16, presents undulations 34 that extend vertically.

Plane 2 and retaining tank 4 are preferably made of polyethylene.
