FR2861661A1 - Open carrier reinforcing system for transport vehicle, has box with chain assuring good gap between lateral walls, where system is raised during unloading open carrier to provide additional height - Google Patents

Abstract

The system has a box closed at its front end by a front wall and on sides by lateral walls (4). The box has a chain (7) arranged transversally on both sides of the lateral walls. The chain assures good gap between the lateral walls. The system is raised during unloading an open carrier, to provide an additional height. The chain is fixed to a hydraulic jack (5), at each of its ends. An independent claim is also included for a transport vehicle comprising an open carrier that includes a reinforcing system.

Description

The invention relates to a vehicle dump reinforcement system of

  transport, to a bucket comprising said system and to a vehicle comprising said bucket.

  The invention also relates to a use of the bucket for the transport of solid materials arranged in bulk.

  Some transport vehicle bodies are used to transport bulk solid materials. These materials, for example household waste, common industrial waste, are loaded in bulk in the bucket using loading means, such as grapples.

  The buckets made of ductile metal, such as aluminum, and which can contain large loading volumes (from 85 to 100m3) can then undergo strong deformations due to blows and shocks received during loading by the grapples. These deformations can cause the rupture of the welds of the side walls.

  Thus the low rigidity of the loading box causes frequent refurbishment operations and therefore very expensive.

  Also to overcome these problems of deformation of the body, there is a fixed reinforcing chain, transversely on both sides of the side walls of the sides of the bucket. This chain is arranged on the upper part of the body.

  This thus makes it possible to stiffen these side walls, and to halve the range between these two walls when the bucket is loaded.

  However, crates used to transport solid materials in bulk are also equipped with moving floors. These floors allow the 2861661 2 automatic unloading of materials when the bucket is raised using a tilting bridge.

  Also the presence of a fixed chain on such moving floor bucket has the major disadvantage of causing the blocking of materials during unloading because of their winding around the chain, and therefore a significant risk of accident for users present during unloading and who would be obliged to intervene manually.

  Therefore, there remains the need to have a bucket for transport vehicles whose side walls are stiffened so that they can withstand without deformations shocks and blows related to loading, while being able to use the tilting bridges during unloading so to optimize the unloading time of materials without the need for manual intervention.

  The invention therefore relates to a vehicle dump reinforcement system comprising a box closed at its front end by a front wall, and on the sides by side walls, said box comprising a chain arranged transversely inside the body. box on either side of the side walls.

  This system is characterized in that the chain is fixed at each of its ends to at least one hydraulic cylinder.

  The system according to the invention has the advantage of allowing a significant time saving in the unloading of materials, and therefore of energy due to the lower fuel consumption to operate the tipping body for emptying.

  2861661 3 This system also provides better safety for personnel involved during the unloading phases.

  The invention also relates to a transport vehicle body comprising the system as defined above.

  Another object of the invention is a transport vehicle comprising a frame and a bucket as defined above.

  Finally a final object of the invention is a use of the bucket defined above for the transport of solid materials in bulk.

  The cylinder of the system of the invention may preferably be arranged vertically in the thickness of the inner wall of the bucket.

  Preferably, each end of the chain can be attached to an assembly comprising three aligned cylinders substantially parallel.

  The chain used may preferably be between about 2.40 and 2.50 meters in length.

  The invention will now be illustrated with the aid of the accompanying drawings which follow and which are given solely by way of example of embodiment.

  FIG. 1 represents a three-dimensional diagrammatic view of the reinforcement system according to the invention, fixed in the thickness of an inner wall of a transport vehicle, and placed in the lower position, FIG. 2 represents a three-dimensional schematic view of the reinforcing system according to the invention fixed in the thickness of an inner wall 2861661 4 of a transport vehicle, in the high position.

  As shown in Figures 1 and 2, the dump reinforcement system of the invention represented by the general reference 1, comprises a metal support 2, equipped with fastening means 2a. The fastening means 2 allow it to be fixed to the inner wall 4 of the bucket.

  The support 2 comprises, in this example, three jacks 5 aligned, substantially parallel. On the upper part 6 of the system 1 of the invention is arranged a chain 7, fixed substantially in the central position.

  Each cylinder 5 comprises in known manner a cylinder 8 in which is disposed a piston (shown in Figure 2, and symbolized by the reference 9). Each piston 9 moves back and forth vertically in the cylinder 8 under the action of a hydraulic pressure. The cylinders are actuated from a control means (not shown) disposed on the transport vehicle.

  The system according to the invention is fixed in the inner wall of the two side walls 4 of side facing each other, of the bucket of the transport vehicle.

  The system of the invention operates as follows.

  When loading solid materials in bulk, the system of the invention 1 is arranged in the low position. The chain 7 ensures the rigidity of the body of bucket, while ensuring the proper spacing 2861661 5 between the two side walls 4. The walls 4 thus maintained avoid being deformed during blows and shocks given when loading the bucket.

  When unloading the bucket, an operator positions the system 1 of the invention in the upper position, thus giving an additional height, for example about 50cm, between the upper part of the bucket and the chain 7 reinforcement.

  It therefore has no obstacle to the correct and rapid flow of solid materials.

  Once the bucket has been unloaded, the system of the invention is returned to its low position in the thickness of the inner wall of the bucket.
