Definitions

• This invention relates to a vehicle for use in carrying bulk material such as coal, mineral ores, grain and like particulate materials in road or rail or other transport vehicles.
• a wide range of constructions have been proposed and used in relation to vehicles for transporting bulk materials, such as those referred to about, and there is generally a conception that one of the principal requirements of such a vehicle, is the ability to be able to discharge the load in a manner which will enable the vehicle to remain substantially stable and yet will permit a rapid gravity induced discharge of the material from the vehicle.
• the problem of stability of the vehicle is of particular concern in relation to vehicles which run on a fixed track, commonly referred to as rail vehicles, as the width of the track is normally considerably less than that of the vehicle body of a conventional road vehicle.
• the rail vehicle to have a somewhat greater carrying capacity than the road vehicle, that is when considered on a single unit basis.
• a vehicle comprising a chassis supported on a plurality of wheels to render it mobile, a load carrying body supported on the chassis, said body being operatively mounted on the chassis to be selectively movable relative thereto upwardly and laterally to a discharge position where the load can be discharged to the side of the chassis from the bottom of the body. More specifically there is provided a vehicle comprising a chassis supported on a plurality of wheels to render it mobile, a load carrying body supported on the chassis for movement relative thereto in a vertical direction and a lateral direction relative to the chassis, said body including a selectively openable discharge passage arranged to discharge material from the bottom of the body laterally to one side of the chassis when the body is raised and laterally displaced.
• the body has a floor structure forming the major portion of the bottom of the body, said floor structure being mounted for pivotal movement relative to the remainder of the body from a position closing the bottom of the body to a position downwardly inclined from one side of the body toward the opposite side to form in that position a shute to direct material to gravity flow from the body down the shute to be discharged to one side of the vehicle.
• the body retains a substantially upright relation to the chassis as it is raised and moves laterally with respect to the chassis as it is raised to the discharge position.
• the body incorporates a base or floor forming the bottom of the body, and is arranged to move relatively to the body, as the body is raised and moved laterally so as the base forms a downwardly inclined shute extending from the body to the one side of the chassis, to occupy a discharge position.
• the base of the body is hingedly connected to the remainder of the body, along an axis parallel to the longitudinal edge of the body remote from the side of the chassis over which the contents of the body are discharged.
• the body has, along each of the respective lateral ends, a downwardly open pocket, and the corresponding lateral edges of the base have a respective wing that is located in the pocket when the base is in the position to close the bottom of the body in the normal transport position.
• the base pivots downwardly and the wings are drawn outwardly from the pockets to form extensions of the respective end walls of the body. This ensures that the contents of the body, during discharge, all move down along the inclined base of the body to be discharged from the side of the vehicle, and do not spill over the lateral edges of the base when downwardly inclined.
• the wings may be made of an elastomeric material, such as a natural or synthetic rubber, that will resiliently stretch to form the wing as the base of the body is lowered to the downwardly inclined discharge position, and will resile as the body is returned to the horizontal normal transport position.
• elastomeric material such as a natural or synthetic rubber
• the body is raised as well as laterally displaced, results in the base, when in the discharge position, having a substantial inclination to the horizontal, the contents of the body will be rapidly gravity discharged, and there will be a minimum or no material left in the body.
• the lower end of the base is laterally withdrawn from the pile of material created by discharge from the body, thus further ensuring complete depositing of the full contents of the body. Further as the material is discharged through the bottom of the body across the full cross-section of the body thereby achieving a very rapid dumping of the contents. Also the lateral displacement of the body results in the contents being deposited outwardly of the path of the vehicle wheels to not interfere with the passage of the vehicle wheels during entry and exit of the vehicle.
• Figure 1 is a side view of a rail vehicle incorporating the present invention
• Figure 2 is an end view of the vehicle as seen in Figure 1 with the body in the lowered transport position;
• Figure 3 is a view similar to Figure 2, but wherein the body is raised to the discharge position.
• FIG. 1 of the drawings there is shown a side view of a rail truck incorporating the present invention and comprising a chassis 28 supported at the respective end by bogy wheel assemblies 29 and supporting a body 30, of generally rectangular cross section, suitable for carrying bulk particulate materials.
• the body 30 is of a generally rectangular cross section with the top closed by a canopy 6 having a central longitudinal opening closed by a hinged door 7. Load of the vehicle is through the opening when the door 7 is open.
• the body 30 may be of a metal construction, such as steel or a suitable grade aluminium, the walls being either of a solid construction or a frame work with a liner of flexible material such as rubber or like synthetic material such as polyurethane.
• the floor 10 of the body 30 is of a separate rigid construction and is pivotally connected to the one sidewall 3 of the body 30 to be pivotally movable from a closure position spanning the bottom of the body 30, as shown in Figure
• the floor 10 is pivotally connected about a fixed axis 9 to the vehicle chassis 28 to permit the floor 10 to pivot thereabout to form a downwardly directed shute as seen in Figure 3.
• the opposite end 5 of the floor 10 pivotably connected to the body 30 at 8 and is connectabie at 13 to a first cable 20 of a crane (not shown).
• the crane is also connected by the second cable 21 to the opposite wall of the body 30 as indicated at 22.
• a suitable crane (not shown) is connected to the container cables 20 and 21 at the common point 25 whilst the container is in the position as shown in Figure 2.
• the cables Upon the crane raising, the cables cause the body 30 to be raised and thereby permit the floor 10 to pivot about back of the axes 8 and 9 and the upper end is displaced progressively towards the right as seen in Figure 3 until the fully raised position has been reached, as seen in Figure 3.
• the body 30 is displaced a significant distance to the right, and the floor 10 of the body 30 has pivoted downwardly and displaced outwardly to the position as indicated at 32 in Figure 3.
• each end of the body a wing 11, attached along the lower edge to the floor 10.
• the upper end of the wing when the wing is in the lower most position of the floor, is located a short distance above the lower extremity of the body 30.
• the wings 11 prevents the material being discharged from passing spilling over the opposite edges of the container floor, and ensures that all of the contents are delivered over the lower end of the inclined floor.
• the wing as shown are of a rigid construction such as sheet metal, attached to the floor, and a pocket is provided in the end wall of the container body, into which the wing retracts when the container is in the lowered transport position.
• This pocket is of a rigid closed construction so that when the container is filled with the material being handled, such material will not enter the pocket and potentially interfere with the effective withdrawal and retraction of the rigid wing 11.
• a pocket may also to provided to protect same as just described.
• the wings may be made of a suitable elastomeric material such as high quality rubber or polyurethane which is anchored both to the end wall of the container and to the floor of the container, so that when the container and floor are in the normal mobile position, as shown in Figure 2, the rubber constituting the wing is in a low degree of tension.
• a suitable elastomeric material such as high quality rubber or polyurethane which is anchored both to the end wall of the container and to the floor of the container, so that when the container and floor are in the normal mobile position, as shown in Figure 2, the rubber constituting the wing is in a low degree of tension.
• two hydraulic cylinders 14 and 16 are provided, cylinder 14 being pivotally connected at 15 to the vehicle chassis and at the upper end 15a to the floor 10 of body.
• the cylinder 16 is similarly pivotally connected to the bracket 22 on the side 24 of the body 30 which is also the anchorage point of the cable 21, and at the lower end to the container floor at
• the two cylinders are interconnected by hydraulic lines 14a and 16a so that a closed circuit is formed between the two hydraulic cylinders whereby each remains full of pressurised fluid at all times, with the fluid transferring therebetween.
• the displacement of fluid from one end of each cylinder results in the delivery of fluid to the opposite end of the other cylinder thereby assisting in the lifting action and in maintaining the container in a stable upright position.
• the cylinder 16 prevent the opposite side wall 30 deflecting inwardly under the effects of the tension in the cable 21.
• the fluid flow between the cylinders 14 and 16 is reversed as the container is lowered by the crane to the closed position as shown in Figure 2.
• the hydraulic lines interconnecting the cylinders 14 and 16 may each have a control valve 18a and 18b which may be selectively closed to lock the container in a selected position. It is desirable to close said valves where the container is fully lowered so that the container is locked in position during travelling.
• the lifting of the container may be effected by other mechanisms as a substitute for the crane, one being to connect the hydraulic cylinder 14 and 16 to a suitable fluid pressure source, such as a pump. In such an arrangement the fluid would be delivered directly and independently to each of the cylinders. Also a mechanical mechanism may be used to effect the raising and lowering of the container.
