Description

The invention relates to a container for the transport of bulk materials, in particular container wagons in railway freight, with a container for receiving the bulk material having saddle roof-like arranged floor elements and side walls with side flaps, which are articulated in the region of their upper longitudinal edges on the side walls and so outwardly in an open position are pivotally, the container having a substantially rectangular steel frame construction with two upper side rails, two lower side members, upper and lower cross members and Eckstehern, wherein the container suspended from the upper longitudinal and transverse beams and with its bottom elements to the lower side members is supported from the outside.

Such a bulk container is for example from the AU 2005202851 A1 known. In addition to the side flaps baffles are hinged pivotally in the region of the lower longitudinal edges of the side walls, so that in the closed position in each case a side flap with a baffle perpendicular and side by side. A discharge of the bulk material is only possible on the side of the container positioned conveyor belts, since in the open position, the baffles protrude relatively far outward. A complete discharge of the container therefore also requires the use of vibrators or vibrators. The KR 2013 0059820 A discloses a further container, which also has designed as a pivotally mounted flaps slide plates which are pivoted in the position of use obliquely outwards and laterally project beyond the container, but when not in use must be folded up inside the container, so that unlocking and locking the chutes is required.

The invention has for its object to carry out a container of the type mentioned above, such that it has the required stability for the transport of heavy bulk materials and can be unloaded without residue by gravity into a deep bunker.

The object is achieved according to the invention in that the bottom elements extend beyond the lower side members and continue as sliding plates, which are integral with the bottom elements and inclined at a smaller angle to the vertical than the bottom elements and their ends are scarce with the side flaps closed or just within the largest container width. Due to the steel frame construction, the container can be designed such that a stable positioning of the container is ensured. The inventive course of the floor elements and their extension as sliding plates allow it to empty the container residue-free and without contamination of the container wagon in a conventional underground bunker.

For a residue-free emptying of the container, the sliding plates are designed according to the invention with the bottom elements in one piece. In this context, it is also advantageous if the sliding plates at an angle of at most 25 ° to the vertical and when the bottom elements at an angle of at most 50 ° to the vertical. The design and arrangement of the sliding plates according to the invention thus effectively protects the container car from contamination during unloading of the bulk material.

The container according to the invention is further designed such that it has an upper and a lower container portion, wherein the upper container portion has two end walls inclined inwards from the upper cross members and two substantially vertically oriented longitudinal walls which are each provided with a V over their length. are provided shaped outward projection. These V-shaped projections enlarge advantageously the loading volume of the container. Of course, care is taken to ensure that the container remains standard despite these projections.

For stability reasons, it is also advantageous if the lower container portion is divided in the longitudinal direction into at least two cargo spaces, each having a pair of side flaps.

In order to ensure proper opening and closing of the side flaps of the holds, an actuating mechanism is provided which allows a simultaneous opening of the side flaps of each loading space, said actuating mechanism for each pair of side flaps comprises two mechanisms which these side flaps in the region of their end portions for opening and Actuate closing and are operatively connected to each other. These mechanisms can be actuated pneumatically or hydraulically and thus executed particularly reliable.

In a further embodiment of the invention, parking brackets are arranged at the lower, free end edges of the sliding plates, which allow a parking of the container at least in the empty state. The brackets are advantageously designed and positioned so that they allow stacking empty containers on top of each other.

The container shown in the figures is a container for the transport of bulk material, in particular for the transport of heavy bulk material, such as ballast or ores. The container has as a supporting element a cuboid steel frame construction 1 in a particular standard dimensioned length of for example 30 feet or 9125 mm. In the illustrated embodiment, the steel frame construction 1 comprises two upper side rails 2 and two lower side rails 3 on the longitudinal sides, two upper cross beams 4 interconnecting the upper side rails 2 at their ends, and four lower cross beams 5. As particularly Fig. 4 shows, connect two of the lower cross member 5, the lower side members 3 in its central, central region, in each case a further lower cross member 5 connects slightly inwardly offset the longitudinal members 3 in the region of their end portions. Vertically extending corner posts 6 each connect the ends of the upper longitudinal members 2 to the lower longitudinal members 3 on the end faces. All the supports 2 to 6 are welded steel profiles. The lower cross member 5 support in still descriptive manner an opening mechanism of also to be described side flaps 19 of the container. Above all, the lower longitudinal members 3 ensure transmission of the forces occurring to the transport vehicle, in particular a container carrier wagon 32 (FIG. Fig. 6 ) in rail transport of the railway. In the lower side members 3 are for fastening the container on the container wagon in the usual way according to ISO standardized fittings 7 ( Fig. 4 ), which are arranged, for example, at the ends of the lower side members 3 and in pairs at a distance from the ends, for example at a mutual distance of 20 feet. The lower side members 3 have on their underside also not shown openings, which can accommodate the unused container pin of the container wagon.

In the steel frame construction 1, a container 9 is inserted and connected thereto, in particular welded. As a result, the container 9 "hangs" on the upper longitudinal and transverse beams 2, 4 and is supported on the lower longitudinal beams 5. The container 9 has an upper container portion 9a and a lower container portion 9b (FIG. Fig. 2 ) on. The upper container portion 9b extends in the vertical direction over 30% to 45% of the distance between the upper and lower power carriers 2, 3. The upper Container portion 9a has in each case an inwardly at an acute angle α ( Fig. 2 ) from 20 ° to 45 °, in particular in the order of 35 °, extending to the vertical and connected to the upper cross members 4 end wall 10 and two substantially extending in the vertical direction longitudinal walls 11, which over its length in each case with a cross-section triangular projection 12 are provided, which increases the cargo space. Each two support profiles 13 ( Fig. 4 ) run along the outer sides of the end walls 10 between the upper cross member 4 and the upper edge of vertical end walls 14 of the lower container portion 9b. The lower container portion 9b extends between the two outer lower cross members 5 and has in its central central region two parallel to the end walls 14 extending, mutually small spaced intermediate walls 15 which divide the lower container portion 9b into two equal cargo holds. Down to each of these holds is bounded by two mutually saddle roof-like running, symmetrically arranged to the longitudinal axis of the container and the same size bottom elements 16. The end walls 14 and the intermediate walls 15 are reversed V-shaped according to the course of the floor elements 16 wrong. The base elements 16 extend beyond the longitudinal members 3, which are adapted in cross section over the respective longitudinal sections, in particular approximately triangularly shaped. Accordingly, the floor members 16 extend beyond the steel frame structure 1. The lower longitudinal sections 17 ( Fig. 2b ) of the floor elements 16 are thus supported on the upper sides of the lower side members 2. Below the projections 12 of the longitudinal walls 11 welded and not shown U-profiles are used for the storage of hinges 18 (FIG. Fig. 2a ) of the already mentioned side flaps 19 which are perpendicular in their closed position. Each of the two holds is bounded by a pair of side flaps. Each side flap 19 has a peripheral frame 19a, which gives the side flap 19 such rigidity that the side flap 19 against the adjacent parts of the container without special seals, therefore with steel against steel, preferably in labyrinth design, can be sealed.

Along the lower longitudinal edges of the floor elements 16 close steel profiles 21 whose outer surfaces slide plates 22 (FIGS. Fig. 3a ) which are at an angle β to the vertical, which is smaller than the angle γ, under which the bottom elements 16 are arranged to the vertical, wherein γ is 30 ° to 50 °. The angle β, which include the sliding plates 22 with the vertical, is 10 ° to 25 °, in particular of the order of 20 °. The sliding plates 22 are made in one piece with the bottom elements 16 and form extensions of the floor elements 16. The sliding plates 22 prevent contamination of the transport vehicle or the container wagon during unloading of the load and support a residue-free discharge. The lower edges of the sliding plates 22 form the lowest points of the container. At the container outer ends of the sliding plates 22 brackets 23 are arranged, on which the container can be parked on the ground, with a parking of the container for weight reasons only in the empty state is possible. The brackets 23 are also preferably designed such that they allow stacking of empty containers on top of each other in addition to parking on the ground. The arrangement of the sliding plates 22 and the brackets 23 is on the container so far outside that the slide plates 22 laterally of the frame side member 33 of the container car 32 (FIGS. Fig. 6 ) run when the container is on the container car 32. The end edges of the slip plates 22 are located just inside the largest container width b ( Fig. 3 ).

Each of the two pairs of side flaps 19 can be opened by means of a multi-part actuating mechanism 24 for unloading the container and then closed again. Each actuating mechanism 24 includes two mechanisms 25 which are constructed substantially coincident. Each of these mechanisms 25 actuates the paired side flaps 19 at each end portion. Components of the illustrated embodiment of the mechanisms 25 are, in particular Fig. 5 shows two pull / push rods 26, one end of each of which is articulated to vertical elements 19b of the side flap frame 19a. The other end of each pull / push rod 26 is in each case connected to a slightly arcuate shaped tilting element 27a, 27b, which tilting elements 27a, 27b in turn to a central rocker arms 28 are articulated. The rocker arm 28 is provided with a shaft 29 running longitudinally and parallel to the longitudinal axis of the container (FIG. Fig. 4 ), which thus also connects the two mechanisms 25 together. The shaft 29 is arranged on vertical supports 5a, which are fixed to the lower cross members 5, respectively. Each of the two shafts 29 is rotated by pneumatic cylinder 31 in rotary motion, wherein in the illustrated embodiment, two pneumatic cylinders 31 are provided per shaft 29, which are arranged or supported on the lower side members 3. A rotation of the shafts 29 by the pneumatic cylinder 31 causes a rotation of the rocker arm 28 and thus on the tilting elements 27a, 27b a moving apart of the pull / push rods 26, so that the two side flaps 19 in their open position ( Fig. 5 ) to be brought. In the closed position, the two tilting elements 27a, 27b are in an overtemp situation. In addition, an auxiliary lock can be provided which protects against unintentional opening of the side flaps 19. The actuating mechanism 24 allows in the open state, an outer width b 'of the container, for example, 4,300 mm, measured between the outermost edges of the two side flaps 19. This outer width b' allows unloading of the container in existing underground bunker. The actuating mechanism 24 can be put into operation via an operating panel which, for example, has one rotary / sliding valve per side flap pair, that is to say per loading space. It can be located on each side of the container one of the control panels. The compressed air for actuating the intended pneumatic cylinder 31 can be made by connecting the container by means of quick couplings to the main tilting air line of the container wagon.

Fig. 6 shows two coupled container wagons 32 with positioned and fastened containers, wherein Fig. 6 has been omitted the reference numerals for the components of the container. On the longitudinal members 33 of the carriage frame of the container car 32 are in the positions that are adapted to the corner posts 6 of the container, car consoles 34 inserted in flat recesses of the side rail 33 and secured with screws 35. As Fig. 6a show the car consoles 34 Ecksteherendabschnitten the container associated support surfaces 36, on which the Ecksteher 6 are supported in longitudinal direction or direction of longitudinal forces acting can. In each case, a bolt 37, which is welded to the carriage console 34 and which is inserted into an opening in the side member 33, serves as the force-receiving element ( Fig. 6b ).
