Description
~6~ i3 IMPROV~:MENTS IN LOADING CAGE: FOR BUL~ GOOI)!~
.
.~
This invention relates to a loading cage for bulk goods, ~or example ore, broken rock and the like, intended especially but not exclusively for haulage cars and of the type compris-ing a structure designed as a frame, a skeleton or the like and within said structure a layer of an elastomer material rorming at least the bottom of the loading cage.
It is a known measure to line such loading cages and other goods and transport containers ror bulk goods with an elasto-mer material in order to reduce the wear of the cage walls and bottom which primarily is caused by the bulk ~oods pieces dropping down at the filling of the cage, which pieces at the moment of their impact can have in certain cases an energy content of up to 25 tonmeters. This elastomer or wear-resis-tant rubber layer serving as wear lining was from the beginn-ing and in certain constructlons still is applied rigidly to the rigid walls and bottom of the ca~e. Consequently, the in-herent elastic properties of the elastomer material cannot fully be utilized for damping or absorbing the energy o~ the bulk goods pieces dropping down and, instead, the thickness of the elastomer layer must be increased in order to avoid percussions and rapid wear. These known linings, therefore, : ,. ,:.

~ ~ 9 ~ 2 -are expensive and very heavy, thereby limitin~ their practical use, especially in the case of road haulages ~rhere greatest possible carrying capacity is desired.
In order to eliminate these disadvantages, it was proposed to divide the elastomer layer servin~ as a wear lining into a plurality Or plate-like pieces, each forming a wall and bottorn portion, respectively, in the cage and each individually be attached detachably in several points along its edges to beams comprised in the structure, between which beams the plates are clamped spaced from the structure proper, so that they can springily yield to some extent for the bulk goods pieces dropp-ing down, in the same manner substantially as a so-called tram-poline. In order to enable the elastomer material used for this purpose to take up the tensile stresses to which it undoubtedly will be exposed, and in order not to have to make the distance between the lower surface of the layer and the structure too great, because a great distance would under given conditions reduce the carrying capacity~ the plate-shaped pieces must be reinforced. It is, therefore, previously known to design the reinforcement elastic and arrange it uniformly divided in the pieces. It was found, however, that this known reinforcement does not withstand heavy concentrated loads caused, for example, by large, sharp-pointed bulk goods pieces at the moment of im-pact, but that local damages are caused in the reinforcement, with the result that the entire pieces must be exchanged. For this reason, this type of lining of loading cages has not been .

The object of the present invention, therefore, is to provide a loading cage for bulk goods, with a lining of an elastomer material and applicable in practice for all kind of bulk goods and the like. This object is achieved thereby that the loading cage according to the invention shows the characterizing features defined in the attached claims.
In one aspect of the present invention there is provided a loading cage, preferably for bulk goods, for example ores, broken rock and the like, and intended especially but not exclusively ~or a transport car, comprising a structure formed as a frame-work, skeleton or the like and within said ~ structure a layer of an elastomer material ~orming at least the bottom of the loading cage, characterized in that the elastomer layer is freely suspended with its longitudinal edges within the structure and supported by a carrying layer also freely suspended within said structure and consisting of one or more ropes or like members distributed on several transverse strands along the extension of the elastomer layer in the longitudinal direction of the loading cage.

LQ~ ii9 -3a-ig. 1 is a longitudinal section through an embodiment chosen as an example of the loading cage according to the invention, certain parts thereof being cut away for reason of clearness, Fig. 2 is a partial section along the line II-II in Fig. 1, Fig. 3 is a partial section along the line III-III in Fig. 1, Fig. 4 is a partial section along the line IV-IV in Fig. 1, and Fig. 5 is a section along the line V-V in Fig. 3.
The embodiment according to the invention shown in the drawings refers to a loading cage for a so-called dumper and comprises a basic structure or frame 1 consisting of longitudinal structural members 3 and 4 which may have, as shown, the form of box girders. The structure of the loading cage, thus, has the character of an open frame-work and, therefore, can be built as - .

a relatively li~ht~weight structure, which contributes to an increased carrying capacity o~ the loading cage.
The structure 1 of more or less shell-type is covered on its inside by a layer 5 of an elastomer material, ror example wear-resistant rubber, rorming the side walls and bottom o~ the load-ing cage. The elastomer layer 5 is sus~ended like a hammock wlth-in the structure and supported according to the invention by a carrying layer 6, which also is suspended freely in the structure.
This carrying layer 6 suspended spaced above the structure con-sists of one or more ropes or similar load-carrylng members Or polyester, rayon, nylon or like material, which has a higher ten~
sile strength bU~a lower elastic ductility than the material in the layer 5 and may be assembled of layers with or without twist-ing, and are distributed in the longitudinal direction of the loading cage on a plurality of transverse strands 7, i.e. strands extending ln transverse direction of the loadin~ cage. The thick-ness Or the strands, or more correctly Or the rope or ropes, and the relative space between them, and therewlth the number of strands per running meter, can vary ~rom one case to another, de-pending on the application field and the kind Or goods to be loaded and transported, and determined in view of the desired bearing capacity of the sparse carrying layer 6, which to some extent depends on the thickness of the elastomer layer 5. Owing to the sparse carrying layer 6 consistin~ of ropes, however~ the thickness Or the elastomer layer can be substantially reduced : . :

compared with corresponding layers at the kno~rn structures, at the same time as the distance between the elastomer layer 5 and the structure can be held on a relatively low level.
These factors also contribute efficlently to pro~iding the load-ing cage according to the invention l~ith a high carrying capa-city. In order to prevent damaging percussions~ furthermore, according to the invention the elastomer layer 5 can be provided on its lower surrace with thickened portions 8 directly in front of the structural members o~ the frame. These portions may have the form of coherent ridges or of separate cushions with recesses 9 where necessary for the strands 7. See Fig. 5. Through these recesses the strands 7 also are fixed in their position and thus prevented from moving too much relatlve to each other.
~t the shown embodiment of the invention the ropes have the form Or endless loops, each formingJ two strands 7 and suspended about holders 10 on each side of the structure with well rounded arc-shaped grooves 11 for the loops, so that the loops will not be broken or damaged in another way when they slide relative to their holders. The holders 10 on the forward horizontal part Or the structure 1 are ~astened on the inside Or a bar 12 connected to the longitudinal upper ~irders 4 and simultaneously form support shoulders for the elastomer layer 5, which at its longi-tudinal edges is formed with a suspension strip 1~ engaging behind said ~orward holders 10. The holders 10 on the rearward part Or the structure 1, however~ which is inclined upward and at the embodiment shown slightly tapering, are arranged on the ~069~
out~ide Or said bars 1~, ror the only reason o~ renderin~ it possible to provide the rope loops at the embodiment shown with e(lual length. This has a certain importance with respect to stock-keeping and facilitates the exchange of the loops in the case of possible damages. ~t other embodiments, thus, all hol-ders can be arranged on the inside of the bars 12 or directly on the girders 4 or in another place deemed suitable. In such a case, the support strips 14 especially arranged at the embo-d;ment shown on the inside of the bars 12 ~or sus~ending the elastomer layer on said rearward part of the structure are not required. At the embodiment shown, rurther, separate support shoulders 15 are provided between the forward holders 10 for the elastomer layer 5, but these support shoulders can be omitted, if so desired.
The elastomer layer 5 is clamped against the bars 12 by means of clamping strips 16, which may be ~ormed with a flange 17 embracing the girder 4 and is clamped at the bars 12 by means of nuts 18 and pin bolts 19 or like fasteners secured on the clamping strip. This clampin~ of the elastomer layer 5 is per se sufficient, but in order to prevent leakage between the front wall 20 of the loadin~ cage and the ~orward edge of the elastomer layer, at the embodiment shown said layer 5 is secured on the structure by means of a reinforced holdin~ strip 21 Or, for example, elastomer material provided on said layer. The holding strip 21, more precisely, is screwn by means of pin bolts and nuts on a flange 22 secured in the front wall of the loading , : : ,,. ~ .. . . . .
