DESCRIPTION OF THE INVENTION
The present invention relates to the transport of bulk material by a container supported on or incorporated in a vehicle. A transportation area which uses special discharge facilities is commonly referred to as containers
lower swingarms, which are selected particularly for the reason of their low center of gravity and therefore great stability while unloading. The conventional lower swingarm container h-abitually is a relatively large structure due to the
fact that the angle of discharge of the container to the floor should be sufficient to promote the flow by gravity of the total payload being transported. This inclination of the floor reduces the volume of useful load and / or increases the height of the container since the angle of the bottom of the floor is required
in the form of "V" is sufficient to allow the gravity unloading of its payload, and the required payload capacity. The "V" shape also produces a bottleneck situation at the point of discharge, which can lead to
problems such as shock of the exit and / or jamming of
REF. 29614 hinged or sliding doors in the discharge opening. The bottleneck also increases the discharge time by the need to use a relatively small opening for the strength requirement in order to avoid distortion and the resulting jamming that decreases the flow rate and / or a large product that is not susceptible to go through the opening. In U.S. Patent No. 316114B to Konig, a train trailer for transporting particulate material having box sections mounted on a chassis in longitudinal general alignment, with the inner end of each case open, is described. Each of the boxes is hinged at its lower inner end to the chassis for pivotal movement about the respective transverse axis. This allows each box to be lifted to a tilted position by pivotal movement about the respective axis, whereby the contents of the boxes are discharged through a central opening between the respective hinged ends. Fixed side walls are provided on both sides of the chassis to encompass the open areas between the respective boxes, when the boxes are in the horizontal transport position as in the inclined discharge position. The disadvantage of the construction of Konig in the first place is that each of the boxes is rotated in the lower inner corners of the same, and that the contents of the two boxes, when the boxes are tilted up, is discharged through of a single fixed lateral opening provided in the vehicle floor between the inner ends of the respective boxes. This construction limits the speed at which the contents of the boxes can be unloaded, and has a potential to promote stability due to the degree of inclination of the boxes necessary to ensure discharge of the total content, at an acceptable speed. An important factor in the form of transport equipment is that it must be capable of transporting a substantial payload, together with the ability to quickly discharge the payload while maintaining a high degree of vehicle stability during tilting of the load useful, so that the risk of overturning the vehicle is reduced laterally with the accompanying risk of damage to people as well as damage to the vehicle and substantial loss of operating time. In the Konig construction, there is a central discharge opening of relatively small size, which extends no more than 50% of the width of the vehicle, and therefore severely restricts the speed of discharge of the contents of the vehicle. Second, Konig has each of its bases pivotally connected to the vehicle frame at the lower interior end of the box. This results in the need to lift the outer ends of the respective boxes to a substantial height in order to obtain a reasonable flow rate of material from the boxes through the small central opening. This requires the use of a high angle of inclination of the respective boxes, which substantially increases the risk of the vehicle falling sideways and requires a substantial hydraulic equipment to carry out the lifting of the boxes insofar as there is no counterbalancing effect during the overturning. The object of the present invention is to provide a container for transporting bulk materials having twin dump load carriers inwardly and having significantly improved stability, particularly during the discharge of the contents, and allowing a more effective and faster discharge Of content. With this in mind, the present invention provides a container for transporting particulate materials comprising a chassis, two body portions, each supported pivotally on the chassis in longitudinal alignment, each body being open at the adjacent ends and positioned relatively to define a unit load carrying area, the body portions are selectively pivotal relative to the frame to move the open ends thereof down relative to the frame from the aligned relationship to allow gravity unloading therebetween of the material from the frame. inside of the body portions. More specifically, there is provided a container for transporting particulate materials comprising a chassis, two body portions, each having an open end that is supported on the chassis in longitudinal alignment with the open ends in adjacent aligned relation, a rigid vertical side wall , on both sides of the bodies, fixed to the chassis and covering the union of the aligned body portions, each body portion is connected to the walls to pivot in relation thereto, around the respective axes transverse to the chassis at respective inclined positions, with the open end of each body portion displaced downwardly from the aligned relation. By arranging the pivotal movement of the body portions so that the inner ends thereof move downward to carry out the discharge operation, it allows the pivot or pivot axis to be located intermediate to the length of the body portions. respective, instead of being at the lower end thereof, as in the internal technique, which results in the load being distributed both forward and backward of the pivot axes, so that the effort required to carry dump the body portions to the tilted discharge position.
Further, by placing the axes of rotation in each body portion upwards from the bottom of the floor of the respective body portion, the discharge opening defined by the transverse edges of the respective body portions progressively increases as the inclination of the body portions, thus allowing a very rapid discharge of the contents of the body portions. The increase in the size of the discharge opening, as the body portions are tilted, is proportional to the distance the pivot axis travels from each of the body portion from the open end thereof through which it takes place. the download. In addition, the distance of each pivot axis from each of the body portion from the open end thereof through which the discharge takes place. In addition, the distance of each pivot or pivot axis moves upwardly from the base of the body portion which also increases the size of the discharge opening. The maximum benefit is obtained by a construction wherein the pivot point is displaced both upwardly from the base of the body portion and inwardly, from the open end of the body portion in which the discharge occurs.
The invention will be further described with reference to the accompanying drawings, which illustrate a practical arrangement of a transport container. In the drawings: Figure 1 is a side view of a transport container, incorporating an embodiment of the invention in the mobile form. Figure 2 is a view as in that of Figure 1, in the unloading position. Figure 3 is a perspective view of the chassis of an alternative construction of the container. Figure 4 is a perspective view of a tank for use with the chassis shown in Figure 3. Figure 5 is a side view of a two tank assembly and a chassis, as shown in Figures 3 and 4. reference now to the drawings, it is to be understood that the container shown herein may be assembled, or may be incorporated in a range of vehicles including both rail and road vehicles, and may be in a directed form, mounted on the chassis of a vehicle or may be in the form of a trailer supported on its own wheel formation connectable in a towing relationship to a vehicle. In addition, the container may be in a self-sustaining form which is transferable from one form of transport to another and, in this respect, may be used in conjunction with a road or rail vehicle, or in a ship or air craft. Therefore, in some forms of the invention, the chassis indicated with the number 10 in Figure 3 can be an integral part of the vehicle which carries out the transportation thereof, and in other ways it can be a separate structure which can be permanently or releasably attached to the structural frame of the vehicle. Referring now to Figures 1 and 2, there is illustrated a practical arrangement of a container for transporting particulate materials incorporating two wheels and axle assemblies suitable for operating on a conventional rail track. Other forms of wheel assembly may be used for road use, or the container may not be equipped with wheels but may be loaded onto a suitable vehicle or vessel for transport thereof. The container 40 comprises two body portions or reservoirs 41 placed in an aligned relation on the base chassis 42, mounted on conventional rail carts 43. Mounted on each side of the chassis 42 is a respective vertical side wall 44. Each of the reservoirs 41 is pivotally attached to the respective side walls 44 by respective pivot bearing assembly 45, one on each of the opposite sides of the container. As can be seen, the axis of the respective pivot bearing assemblies 45 are spaced inward from the inner or central end 46 of the respective reservoir, and they are also separated upwards from the base of the deposit. Mounted in a fixed position centrally of the length of the chassis 42 is a fixed dividing wall 46 extending the width of the chassis between the vertical side walls 44. The end of each of the reservoirs 41 adjacent the walls 46 is not provided with an integral end wall but is open, and when the reservoirs are in the horizontal position, as shown in Fig. 1, they make contact with the wall 46 divider to close in that way. In addition, the upper corner portion 48 of the side walls of the reservoirs, adjacent the wall 46, have an arcuate shape having a center in the pivot bearing mounts 45, and extending through a 90 ° arc. . At either end of the chassis 42 a respective telescopic hydraulic piston 50 attached to the lower end 51 to the chassis 42 and the upper portion 52 to the end wall 53 of the reservoir 41 is provided. As the hydraulic pistons 50 expand, each of the reservoirs 43 rotating on the respective pivot bearing assemblies 45 from the arrangement shown in Figure 1, to that shown in Figure 2. As the reservoirs move to the inclined position shown in Figure 2, the inner open end thereof it moves downward and outward away from the divider wall 46, to expose the lower portion 49 of each of the reservoirs and thereby allow the gravity discharge of the contents of the respective reservoirs. As can be seen in Figure 2, the pivotal movement of the reservoir generates a substantial opening 55 for discharge of the contents of the reservoir, and this opening extends across the entire width of the reservoir, thereby providing rapid discharge of the contents. of the deposit. In addition, as the axis of pivotal movement of the reservoir 45 is located at a substantial distance above the floor of the reservoir and inwardly from the end thereof, a downward and rearward displacement of that reservoir position is generated as the reservoir dumps, the entire structure is more stable during the download of the content. Referring now to Figures 3 and 4, the container comprises the base chassis 10 and two body sections 11 (in figure 4 there is shown one) of identical construction which are assembled in use with the chassis 10 in an extreme relation to end, similar to that shown in Figure 1. Each body 11 is of a generally rectangular shape having opposite side walls 12 and an end wall 13 extending between the side walls 12 at the outer end of the structure, to form an open top and an open end of the rectangular box. At the inner end of each body 11 there is no end wall, and each of the side walls 12 is constructed to form an edge portion 14 inclined upwards and backwards. These edge portions 14 are structurally reinforced by members 15, and adjacent aligned end structures 16 on the opposite sides of the body 11 are provided adjacent to the upper and rear end thereof. The chassis 10 is of an open frame structure of a length and overall width suitable for supporting the two bodies 11 when placed in an end-to-end relationship with the lower edges 25 of the butt-open ends. Central to the chassis 10, a rectangular opening 19 is provided which extends through the entire depth of the chassis 10 and is defined by the respective opposite transverse walls 17 and the longitudinal walls 18. Vertically from the chassis 10, on the two opposite sides thereof, are respective bearing pillars 20, each carrying two longitudinally spaced bearing units 21. Each bearing unit is arranged to align with a bearing structure 16 provided in the reservoir that is located therebetween and rotatably secured together to pivotally attach each of the reservoirs to the chassis. When the two body sections 11 are assembled to the chassis with the bearing assemblies in place, the respective transverse edges 25 of the two body sections 11 will be in an abutment relationship, so that the central opening 19 in the chassis is closed to prevent the contents of the containers from escaping through the central opening 19 in the body. chassis. However, before the pivotal movement of the respective body sections 11 around the bearing structures 16 in a manner similar to that shown in Figure 2, the edges 24 of the floor HA of the containers will move in an arcuate movement about the respective bearing structure a substantial distance apart to define a transverse opening to allow the contents of the containers to be discharged by gravity through the central opening 19 in the chassis. In order to optimally limit and avoid spillage of material that is transported in the container, appropriate provisions are made to effect the seal between container components which are subject to relative movement during use. The particular areas where movement occurs is between the walls of the incunable body and the vertical side walls to which the body is pivotally joined and where the transverse edges of the inner end of the body bars engage when in the position of the body. transport. A convenient form of seal is a solid or hollow bar of resiliently compressible material such as a suitable material, for example, an appropriate grade of rubber such as synthetic rubber. It is preferred that the rod be of a diameter that is compressed when assembled between the relevant components of the container to ensure an effective seal. The composition of the rod must also be selected so that the union thereof does not occur as the component of the container moves in relation to one another, for example during the inclination of the bodies. It will be appreciated that, as a result of the pivotal axis of the bodies which is displaced from the edges 24 of the bodies, the edges 24 can be moved apart and downward to create a relatively wide opening therebetween, extending through the entire width of the central opening 19, whereby a rapid discharge of the contents of the body is allowed. In addition, as part of the respective bodies that move downward, in or through the opening 19, during unloading, the resulting load improves the weight distribution and stability of the entire container. The inclination of the bodies 11 can be carried out by hydraulic pistons similar to those previously described with reference to figures 1 and 2, or by appropriate alternative means such as an upper crane equipment provided in the position, wherein the content of the container will be supplied. It is noted that in relation to this date, the best method known to the applicant to carry out the aforementioned invention, is the conventional one for the manufacture of the objects or products to which it refers.
