Description
Australian Patents Act 1990- Regulation 3.2 ORIGINAL COMPLETE SPECIFICATION STANDARD PATENT Invention Title Dump tray The following statement is a full description of this invention, including the best method of performing it known to me/us: P/00/0Il C 1A - la The present invention relates to a dump tray. Preferred embodiments of the invention provide a steel dump tray with two systems of suspension, a suspended rubber mat and 5 suspended steel membrane for the transport of bulk material, with a structure defined by central longitudinal beams, two central main chassis beams, side beams and two divergent beams arranged transversely to those beams, the divergence being defined at the ends of the central main chassis side beams, the main structures being set in the same position as in the original design resulting in a flexible and multifunctional tray. 10 The following request comply the requirements for a dump body capable of transform its traditional floor by using two different materials, without changing the original design and providing a large size lightweight bowl which will transport bulk material preferably for mining operations. Its design (Suspended Dump Body) consists of a rubber wear mator a 15 steel membrane floor (an interchangeable system), at least one crossed beam and a transversal beam divergent to the side walls. Lately, the biggest problem found in mining operations has been to obtain a lower maintenance cost, hence providing demonstrated longer service Life, lower costs per/Ton 20 and a strong and durable construction of the equipment to be tested in severe mining applications. In addition, the high price of minerals such as copper, gold and coal has directed the mines to produce high volumes of mineral in a short period of time in order to increase the net Return on Investment rapidly. 25 Different kind of trays and manufacturing processes has been undertaken. One clear example is the wear resistant steel trays which contain a mixture of steel and rubber floor among other components. Within the wide range of patents established in Chile, we highlight the requests number 6-2003 and 873-2003 which involve the construction and configuration of lightweight trays for Suspended Dump Bodies. 30 The main objective of designing trays with the characteristics mentioned previously is -2 building a hybrid that could operate in different applications and mining operations without modifying the features of the original product by reducing the total empty vehicle weight to increase the payload. In addition, its flexible rubber floor reduces the noise caused by the loading impact as well as the vibration produced. 5 In order to achieve that principle the new concept incorporates at least one transversal beam divergent on the sides which eliminates the transversal beams underneath of the tray. The new design includes a new centre of gravity (COG) providing higher load stability and safety advantages while the truck is carrying the load attributable to the rubber floor which 10 is anchored and tensioned into the sites of a high-tensile skeleton steel frame. The new design incorporates the rubber floor as the main feature by replacing the conventional steel floor. The steel components are adjusted to the existing design and keep the same centre of gravity and the curvature. 15 The present invention will now be described, by way of non-limiting example only, with reference to the accompanying drawings, in which: Figure 1. Tray new design general view Figure 2. Tray new design basement view 20 Figure 3. Tray new design front view Figure 4. Tray new design side view Figure 5. Tray new design rear viewwith Rubber Liner Figure 6. Canopy view Figure 7. Tray new design Top view 25 Figure 8. Front view of the Canopy Figure 9. New Tray design General View of the steel membrane Figure 10. New Tray design system attached to the steel membrane. The new tray consists (Figure 2) of two central lengthwise beams (1 and 2), two main side 30 beams (3 and 4) and two transversal beams across (5 and 6) which diverge to the side beams (3 and 4).
-3 The beams (5 and 6) are a variable crossed section in the centre point and opposite to the sides forming an H figure. This design of the beams creates a toehold on the sides; the beams (5 and 6) as shown in the figure 4 produce four support points in the main central beam which compared with the conventional design of a Suspended Dump Body it just 5 supported by 4 main transversal beams, as a result there's a weight reduction of the complete frame (less steel structure). The transversal beams (5 and 6) are curved as shown in the Figure 5 which includes the divergent point where they still keep their shape. This feature allows the rubber floor to be 10 supported by the transversal beams diminishing the tension over the ropes (15) underneath the wear mat (14). The new design illustrates a polygonal front wall (7) formed by five straight plates (8) resulting in an entire curved wall as shown in the Figure 1 and 3. Besides the front wall 15 there are two transversal side beams (9) forming a rigid front wall. The upper end of the front wall (7) contains a curved canopy (10) formed by various plates of different thickness where the thickest of them is anchored to the front wall (7) to reduce the thickness towards the front side of the frame. 20 The canopy (10) in Figure 6 includes two transversal beams (11) in H and a gousset interior structure (12) forming the main support point that prevents the oscillation of the canopy in relation to the front wall. The floor (13) in Figure 7 of the tray comprises a rubber wear mat of different thickness 25 customised to each operation and material; it's remarkably thicker at the back site (14) where mainly the payload produces higher wear and tear. The floor is made of a flexible material resistant to the payload preferably rubber,elastic bands, polymer resins, rubber with steel reinforce, rubber with steel backing reinforce or nylon, among others. The rubber wear mat is anchored to the side walls holes (3 and 4) through high capacity 30 synthetic suspension ropes (15) in Figure 5. Once those components are installed, the floor will be suspended when the tray is empty and it will be supported in the cross beams (5 -4 and 6) when the tray is loaded in Figure 5. As a result, the tension of the floor will decrease in comparison with a traditional suspended dump body floor; in addition, the side beams will support lower weight by 5 themselves as in the traditional design. The new design presents the steel membrane floor (16), which is a curve piece made of special steels capable of holding over 900 KPa in severe abrasion conditions. It's simply a set of joined front and transversal beams as per the following figure (17) in Fig. 9). 10 Along with those components new components have been incorporated such as the new C clamps (18) with bolt attached (19) and bracket clamps (20) in Fig 11, which are adjusted to the side wall and they are screwed to the steel membrane. (Fig 10). 15 On the other hand, the structure of the crossed beams could differ accordingly with the size of the tray. As an example, one tray could be formed by one crossed beam with two traditional transversal beams or three crossed beams. The main structures such as canopy, front wall, side walls and chassis are set in the same position as in the original design resulting in a flexible, multifunctional and hybrid steel 20 and rubber tray. While various embodiments of the present invention have been described above, it should be understood that they have been presented by way of example only, and not by way of limitation. It will be apparent to a person skilled in the relevant art that various changes in 25 form and detail can be made therein without departing from the spirit and scope of the invention. Thus, the present invention should not be limited by any of the above described exemplary embodiments. Throughout this specification and the claims which follow, unless the context requires 30 otherwise, the word "comprise", and variations such as "comprises" and "comprising", will be understood to imply the inclusion of a stated integer or step or group of integers or steps -5 but not the exclusion of any other integer or step or group of integers or steps. The reference in this specification to any prior publication (or information derived from it), or to any matter which is known, is not, and should not be taken as an acknowledgment or 5 admission or any form of suggestion that that prior publication (or information derived from it) or known matter forms part of the common general knowledge in the field of endeavour to which this specification relates.
