SHEET 1 OF 4 mew? 1 fmmi PATENTED JUN] 5 19m 3; 584 583 SHEET 2 0F 1 MONORAIL TRAIN BACKGROUND OF THE INVENTION Field of the Invention This invention relates to conveyors of the kind comprising a ground mounted monorail trackway, and a carriage or carriages movable therealong, and positively retained against lateral angular tilting relative to the trackway by virtue of the wheels being so arranged as to define collectively a passageway extending longitudinally of the carriage of a crosssectional shape to receive at least a portion of the cross section of the trackway, such cross-sectional shape intrinsically preventing angular tilt of the carriage relatively to the trackway about a reference axis extending longitudinally of the latter. Such conveyors are hereinafter referred to as monorail conveyors of the kind specified.
In a typical form of trackway, the latter comprises a pair of laterally spaced rail elements, the lateral spacing of which is too small to provide the requisite stability against lateral tilt of the carriage were the latter to be provided only with wheels running on the upwardly presented faces of the rail elements and freely separable from such faces. Such lateral tilt is, therefore, prevented by provision on the carriage of a wheel or wheels adapted to engage one or more of the following faces presented by the trackway, namely laterally inwardly presented faces of the rail elements, and downwardly presented faces afforded by horizontal flanges at the upper edges of the rail elements.
The invention has been developed primarily for monorail conveyors of the kind specified intended for use in underground mine workings. In this application the tunnels or roads along which the conveyor is required to operate frequently presents steep upward and downward inclinations. If the carriage of the conveyor are required to be propelled by a coupling to a self-propelled locomotive, as distinct from being propelled by connection to a haulage cable extending alongside the monorail trackway, difficulty is experienced in establishing the requisite driving grip between the wheels of the locomotive and the trackway. Such grip cannot effectively be increased by increasing the weight of the locomotive, since this would require the trackway to be formed to a heavier section, or would require the trackway to be supported from the ground by foot or spacer members situated closer to each other than is necessary in the case of cable hauled carriages, and both these factors would materially increase the cost of the installation. Further, it is desirable that a design of trackway common to both a cable hauled system and a locomotive propelled system shall be capable of being utilized.
SUMMARY OF THE INVENTION According to the invention there is provided a locomotive for a monorail conveyor of the kind specified, comprising a body on which is mounted a prime mover, and which is supported by longitudinally spaced bogies, one at least ofwhich is a driving bogie, to enable said locomotive to travel along a ground mounted monorail trackway, incorporating at least one generally horizontal flange, and at least one generally vertical web, and which includes the improvement wherein the driving bogie or each of same comprises a bogie body structure pivotally connected to said locomotive body about an upright swiveling axis, a central group of bogie wheels mounted on said bogie body structure for engaging said flange of said trackway over upwardly and downwardly presented faces thereof, and including at least one driving wheel operatively connected with said prime mover and driven therefrom for engaging one of said flange faces, at least one counterpressure wheel for engaging the opposed one of said flange faces, preload means for urging said driving wheel or each of same on the one hand, and said counterpressure wheel or each of same on the other hand into engagement under pressure with said flange, stabilizing wheels on said bogie body structure at opposite ends of said central group of bogie wheels for engaging opposed laterally presented faces of said trackway, and afforded by said web or webs thereof.
The invention will now be described by way of example with reference to the accompanying drawings, wherein:
FIG. I is a diagrammatic view in side elevation illustrating a monorail conveyor of the kind specified in accordance with one embodiment of the present invention;
FIG. 2 is a view in side elevation and in vertical cross section on the line 2-2 of FIG. 3 showing one embodiment of driving bogie in accordance with the invention for incorporation in a locomotive of the monorail conveyor shown in FIG. 1;
FIG. 3 is a view in end elevation of'the driving bogie of FIG. 2; and
FIG. 4 is a plan view of the bogie of FIG. 2 partly in cross section on the line 4-4 of FIG. 2.
Referring firstly to FIG. l, the monorail conveyor shown comprises two vehicles, of which 1 is: the locomotive, and 2 is a load carrying vehicle. This may be a passenger vehicle, as shown, or adapted for carrying material or articles.
The trackway 3 comprises a plurality of track sections articulately connected together by coupling means at positions 4.
In the coupled train of vehicles seen in FIG. 1, successive vehicles are articulately coupled for swiveling about a vertical axis, and sufficient freedom of movement is provided to allow relative articulation between the vehicles about a transverse horizontal axis.
The locomotive comprises a body including a longitudinally extending base member 5 which is cranked upwardly at its ends, as indicated at 6, one end being bifurcated to receive the corresponding single leaf end of the next vehicle between the limbs of the bifurcated portion, and this limb and the bifurcated portion being apertured to permit of upward projection therethrough of one component ofa swivel bearing on bogies 7 which collectively support the vehicles of the coupled train.
The locomotive I carries a prime mover 8 which may be in the form of an internal combustion engine, such as a diesel engine, having a fuel tank 8a, and driving a variable output hydraulic pump 9.
The locomotive may be equipped with a drivers seat 1a and a control console lb.
Referring in more detail to the trackway, this comprises two laterally spaced rail elements 10, each of channel section, and having vertical webs I1, and upper and lower horizontal flanges 12 and 13.
The two rail elements 10 are connected to each other by foot elements, l0bwhich serve to maintain the requisite lateral spacing between the rail elements, and also space the latter a certain distance above the floor of the ground where the trackway is mounted, for example the floor ofa road or tunnel in a mine working. Typically the lateral spacing between the rail elements would be such that their outwardly presented lateral faces are 778 inches apart, the height of the upwardly presented face of the upper flanges I2 being typically about 9 inches above the level of the floor.
As mentioned, the trackway is composed of structurally separate rail sections arranged end-to-end, and adjacent to the end of each such track section coupling means are provided for connecting same together in end-to-end relation. Conveniently one coupling element may be formed on the foot element, and may be in the form of an upwardly presented cradle of parts cylindrical form, as indicated at 10b, extending transversely of the rail section, with the cradle portion offset longitudinally from the end of the track section concerned, and disposed just beneath the lower flanges 13.
The complementary coupling element of the coupling means comprises a cylindrical member welded or otherwise secured to the lower flanges I3, and extending transversely of the track section at the opposite end thereof, as indicated at We.
The locomotive 1 may be supported at each end by driving bogies 7, or one only of these bogies. may be a driving bogie,
and the other may be an idle bogie, in which case it may be a simplified form as hereinafter mentioned.
Referring now specifically to such driving bogie, the driving wheels thereof 14 are journaled for rotation about a horizontal transverse axis 15 by a bearing provided in a mounting member 16 ofgenerally blocklike form disposed predominately above the trackway. The driving wheels together with tires, preferably formed of duthane rubber, have diameters typically of 8 to 12 inches.
The mounting member is provided with an upwardly projecting post 16a forming a component of a swivel bearing and serving also to couple successive vehicles such as l and 2.
The driving wheels 14 contact the upwardly presented faces of the upper flanges 12 of the trackway.
The underfaces of these flanges are engaged by counterpressure wheels 17 of which there are two associated with each driving wheel 14, these being journaled for rotation about axes 18 extending horizontally and transversely of the trackway at positions offset, one on each side of a vertical plane passing through the axis 15.
The counterpressure wheels 17 are of a diameter somewhat less than the vertical internal dimension of each channel section rail element so as to provide a clearance space 19, preferably having only a small value, with respect to the bottom flange 13. Typically the counterpressure wheels have diameters of 2 to 3 inches. It is advantageous to employ counterpressure wheels having the largest diameter capable of accommodation within the vertical internal dimension of the rail element to provide more favorable compressive loading of the flanges 12 at the zones of contact with these wheels.
All four counterpressure wheels are mounted on a counterpressure wheel support in the form of a longitudinally extending beam element 2!) provided with suitable bearings for the mounting of the counterpressure wheels and supported by suspension elements in the form of hydraulic piston and cylinder units 21 extending upwardly from the beam to which their lower ends are pivoted, and supported at their upper ends by pivotal connection to lugs 22 projecting longitudinally at each end ofthe mounting member 16.
If, as shown, the upper faces and underfaces of the flanges 12 are horizontal, the driving wheels and counterpressure wheels will be mounted in pairs in which the wheels are exactly coaxial with each other; but if these faces re not exactly horizontal, then there would be some departure from exact coaxial relation between the driving wheel pairs and/or the counterpressure wheel pairs.
The mounting member 16 also has downwardly projecting arms 23 with penetrate the beam element, the latter being apertured for this purpose, and engage guide faces 24 formed on the beam element and presented in opposite longitudinal directions.
This arrangement provides ability for the beam element to rise and fall relatively to the mounting member 16 and also undergo some angular movement about an axis 25 on the same horizontal level as the axis 18 and in vertical alignment with the axis 15 by virtue of the convexity of the guide faces 24. However, the beam element is constrained against translatory endwise movement by engagement of the arms 23 with the guide faces 24.
The driving wheels 14 are coupled to respective hydraulic motors supplied with fluid from the pump 9 disposed at the outer sides of the driving wheels and conveniently supported in any suitable manner from the mounting member 16. The pump and hydraulic motors effectively form a transmission means of variable velocity ratio dependent upon the delivery rate setting for the pump.
The driving wheels and counterpressure wheels form a central group of compact dimensions longitudinally of the trackway, and hence able to negotiate abrupt changes of inclination and lateral direction at junctions between straight rail sections. Further, the rubber tires of the driving wheels nrovides a lnncviturlinal cnrpnni nf finulruuarri IMA mt fka gitudinal spacing of the axes 18, and hence the zones of contact between the rigid metal counterpressure wheels 17 and the flanges 12.
At opposite ends the beam element 20 is provided with extensions 26 having vertical bearings 27 for stabilizing wheels 28. These wheels perform a guiding function with respect to the angular position of each bogie about its vertical swivel bearing: one of the stabilizing wheels contacts the inwardly presented face of the vertical web 11 of one rail element and the other contacts the equivalent inwardly presented face of the vertical web 11 of the other rail element. The diameter of each stabilizing wheel 28 is, of course, somewhat less than the lateral separation between the inwardly presented faces of the webs 11.
The arrangement described provides a relatively short bogie capable of negotiating trackway curvatures down to about 13 ft. radius.
Further, the arrangement has flexibility in that either one or two such bogies may be provided on the locomotive. The preload exerted by the hydraulic rams 21 which urge the counterpressure wheels 17 upwardly into contact with the underface of the upper flange 12 of each rail section does not significantly increase the stress conditions existing in the lower flange 13, this being the limiting factor as regards the weight of the locomotive which can be supported by trackway.
The hydraulic fluid necessary to pressurize the hydraulic rams 21 may be derived from the hydraulic pump 9 driven by the prime mover. Alternatively, a manually operated pump, for example in the form of a piston and cylinder assembly operable through a screw mechanism, may be sufficient to provide the requisite pressure of hydraulic fluid to establish the required preload.
If only one driving bogie is required to be provided on the locomotive, the other bogie may be of simplified form, such as that seen at 7a at the extreme right-hand end of the vehicle 2.
Further, although as depicted in the drawings, the body of the locomotive is of rigid form longitudinally, it would be possible for the locomotive to have an articulated body supported at its midposition by a bogie which may be the driving bogie or one of same. In this case, one body section of the locomotive may carry the prime mover, and the parts 8, 8a and 9 already mentioned, and the other section of the locomotive body may incorporate the driving station and be equipped with a seat, such as 1a, and control console, such as 1b.
It will be understood that it would be within the scope of the invention for the two driving wheels which are mounted for rotation about a common axis to be replaced by a single driving wheel ofa width to span both rail elements. Similarly, single counterpressure wheels mounted each on its own axle may be employed instead of coaxial pairs.
Further, instead of using two pairs of counterpressure wheels, or two counterpressure wheels rotatable about axes spaced apart longitudinally and situated fore-and-aft of the driving wheel, a single counterpressure wheel, or a single pair of coaxially mounted wheels may be employed in certain circumstances, for example there the depth of the rail section permits of the accommodation of a counterpressure wheel of greater diameter than those previously referred to. The axis of such counterpressure wheel or wheels would be substantially in the same vertical plane as that of the driving wheel or wheels.
Moreover, it would also be within the scope of the invention to employ two pairs of driving wheels, or two driving wheels of a width to span both rail sections, mounted for rotation about respective axes which are spaced apart longitudinally from each other. In this arrangement, there would be either a single counterpressure wheel, or a single pair of coaxially mounted counterpressure wheels in association with each of the driving wheels, or pairs thereof, as above-described, or each driving wheel, or each pair of driving wheels, may have associated with it two pairs of longitudinally spaced counterpressure of counterpressure wheels may be common to the two driving wheels or pairs thereof, namely that situated at an intermediate longitudinal position relative to these driving wheels.
