Abstract
Description

structure 61 has, between thearm portions cross member 67, first and second secondary groundcontactable wheels - The
arm portions - The
first trolley part 11 has, further, brake means 95, comprising, in addition to friction wheel engaging means (not shown) a brake actuation means housed within acasing 97 and operated by a rotatable wheel 99. - The
second trolley part 13 comprises: second and third jacking means 101, 103, respectively, said second and third jacking means 101, 103, being, subject to differences in certain subordinate constructional features dictated by differences in configuration between the first andsecond trolley parts first trolley part 11, both constructionally and as regards operation of said second and third jacking means 101, 103. For this reason, description of the second trolley part and, especially, of its two jacking means 101, 103, will be confined, substantially, to those features that differentiate the twotrolley parts - The adaptor second parts of each of the jacking means 101, 103, of the
second trolley part 13, are constituted by first and second plates, one only, 105, of which is shown, saidplates 105 being adapted to be readily releasibly secured, respectively, to the adaptorfirst parts hand knobs 113. - Between the plates, as 105, there is a
rigid beam structure 117 comprising ashaft 119, the ends of which have rigid connections with theplates 105; and arigid shaft housing 121 comprising acasing 123 of rectangular cross-section and, fixed within saidcasing 123, atubular member 125 through which extends theshaft 119, said shaft being releasibly secured to thetubular member 125 by readily removable pins, as 127, located, respectively, at the ends of thetubular housing member 125. - Releasibly connected to the
beam structure 117, there is, projecting rearwardly of the vehicle, a second arm-bearingstructure 129 similar, essentially, to that of thefirst trolley part 11 but adapted to be releasibly secured to thebeam structure casing 123, using, as elsewhere in thetrollies casing 123 and the arm-bearingstructure cross-piece 131. - Whereas the adaptor
second part 47 of the first actuation part 29 is integral with the adaptorfirst part 45, and has opposedparallel side walls 55, 57, which are pierced with, in the example, four pairs, H1', H1''; H2', H2''; H3', H3''; and H4', H4'', respectively, of transversely aligned holes, in the case of thesecond trolley part 13,plates 105, constituting the adaptor second parts of the jacking means 101, 103, are adapted to be connected to inwardly-facing vertical flanges, as 133, of sub-framefirst parts flanges side walls 55, 57, of said adaptorsecond part 47. The hole-pairs, as H1', H1'', through saidflanges 133 constitute means whereby saidplates 105 may be correspondingly set at any one of three positions which are vertically displaced with respect to one another along saidflanges 133. - The arm-bearing
structure 129 has, as represented in Fig.5, a ground-contactable wheel 135 on which said arm-bearingstructure 129 may, when separated from thebeam structure 117, be wheeled independently of the remainder of thetrolley 13. - As shown in Fig.5, also, the
casing 123 of thebeam structure 117 has a fixed forwardly projectingframe 137 with a ground-contactable wheel 139 dependant therefrom, and atowing handle 141, pivotal about a transverse hinge axis in theframe 137 rests, when not in use, in contact with the side arm portions of theframe 137. - In use, the
trolley parts missile 19, which is to be found supported, secured to thecradle 15 itself, mounted on a base. - The so-coupled trolley parts are there manoeouvred to bring the rearwardly projecting arm portions of the arm-bearing
structure 129 of thetrolley part 13 to alignment with the socket portions 23', 23'', and, so aligned, the coupledtrolley parts cradle 15 said arm portions penetrating the socket portions 23', 23'', until arrested by contact of the arm portions with the abutments therealong. With the arm portions at the abutment arrested position, holes in the cradle are in alignment with holes in the arm portions, at positions downstream of said abutments. With the holes so aligned, eye-bolts are inserted through the cradle holes and screwed into the holes of the arm portions. - The
front trolley part 11 is next separated from therear trolley part 13 and wheeled to the front of thecradle 15 where, as with thetrolley part 13, the front trolley part is advanced to cause the arm portions of its arm-bearing structure to penetrate the socket portions 21', 21'', and the cradle and arm portions secured together by eye-bolts. - The assembled tricycle vehicle is towed by the towing handle H to the proximity of the sub-wing pylon station that is to receive the
missile 19. The several jackingmeans - The act of capture of the missile at the pylon station affects the aircraft geometry and can and frequently does introduce obstructions, not previously present, the extraction of the now unloaded trolley from beneath the aircraft being a matter of great difficulty, an effective impossibility even, particularly having regard to the unacceptable delay incurred in the time-critical action of missile loading.
- To assist in the task, the each of the trolley parts is, as previously described capable of being disassembled, at least partially, the arm-bearing structures of the two trolley parts being, in each case adapted for separation, in the case of the
first trolley part 11 from the adaptorsecond part 47 of the jackingmeans 23, and, in the case of thesecond trolley part 13 from the cross member connecting the adaptorsecond parts 105 of the jacking means 101, 103. - The jacking means 101, 103, or either of them, of the
second trolley part 13 may, moreover, be angularly displaced, as shown in Fig.6, to a folded lower position, by removal of the appropriate one of thepins 127. These expedients render the ready removal of the so-changed trolley. - In an improved form of a vehicle, in accordance with the invention, illustrated in Figs 12 to 16, a means is provided which permits the lateral adjustment of the arm portions of the arm-bearing structures, or either of them, within a certain limited range, such, for example, 50mm, in either direction from a transverse medial position.
- The need for such a facility for adjustment of lateral position of the arm portions in relation to the remainder of the vehicle arises from the discovery that, the vehicle having been manoeuvred to the closest available position for capture of the missile at a pylon station, the
cradle 15 and themissile 19 supported thereon are yet not in a position and orientation proper for such capture, and, still more, the geometry of the aircraft, sub-wing, may preclude the opportunity for further manoeuvre of the vehicle such as to bring the cradle and missile to the desired capture position in relation to the pylon station. The freedom to adjust, even within quite modest limits, the lateral position of the arm portions, proves to be generally adequate to 'fine-tune' the position and attitude of the cradle to achieve the necessary end, the capture of the missile at the pylon station. - In the improved vehicle construction, the rear trolley part differs from that of the previously described embodiment in that the
arms 129a, 129b, respectively, of the arm-bearing structure 129 are secured by bolt devices, as 143, 145, to bracket members, being, in the case of thearm 129a, bracket members 147a, 147b, and, in the case of the arm 129b, bracket members 149a, 149b, respectively. The bracket members 147a, 147b, are coupled together by means of a spindle which carries aroller member 151, and the bracket members 149a, 149b, are similarly coupled by means of a spindle carrying asecond roller member 153. Theroller members casing 123 with a displacement between them which is determined by presence of first and second parallel struts, 155, 157, respectively, bracket members 147a, 147b being secured to thestrut 155, the bracket members 149a, 149b, to the strut 157. - The aforesaid bracket members are formed with vertical slots which extend through the bracket vertical walls, as 159, 161. Associated with the several said bracket members 147a, 147b; 149a, 149b, there are axially vertically supported spindles on which rollers, 163, 165, 167 and 169 are respectively supported. The aforesaid four rollers project through respective ones of the aforesaid vertical slots with their cylindrical surfaces in contact with vertical side planar surfaces of the
casing 123. - Secured between associated pairs of bracket members, as 147a, 147b, one to each side of the
casing 131, there are first and secondfurther brackets further bracket 171 houses anut element 175. First and second plummer blocks 177, 179, respectively, are upstanding from the flat upper surface of thecasing 123, and aspindle 181, threaded over an end segment 183 thereof, being a segment than that prevailing along the major portion of the spindle, has its ends supported in bearings within said plummer blocks 177, 179, and extends through saidnut element 175 such that saidnut element 175 and said enlarged spindle segment 183 are threadedly engaged. The spindle segment 183 has acollar portion 185 at that end of the segment which is remote from the block 179. Thespindle 181 has arotary knob 187 by which thespindle 181 may be rotated about its longitudinal axis. - In use, rotation of the
spindle 181, consequent upon rotation of theknob 187, employing, if need be, atommy bar 189 to be inserted successively into the several a ngularly spaced radial holes in the knob, causes thenut element 175 and thebracket 171 secured thereto to travel in one direction to the other (according to the sense of rotation of the spindle 181), along thecasing 123, the remote further bracket 173 (being tied by thestrut 155 to the bracket 171), being correspondingly displaced. The range of limited permissible translation of thebrackets collar 185 of the segment 183 and, on the other, by the presence of the plummer block 179. Thearms 129a, 129b, are, naturally, correspondingly laterally displaced, the whole lateral motion of thearms 129a, 129b, with respect to the arm-bearing structure 129 proceeding smoothly, by virtue of rolling contact between therollers casing 123 and rolling contact between therollers casing 123. - The improved form, the subject of Figs. 12 to 16, for the vehicle also incorporates means serving to limit the force capable of being developed between the missile or other store and the pylon and, hence the aircraft wing to which the pylon is attached, at capture of the store. Failure to provide such a means gives rise to the real danger that, by virtue of the high mechanical advantage inherent in the several jacking means of the vehicle, excessive rotation of the jack operating handles, or any of them, would give rise to excessive loading, a loading liable to deform the pylon, the cradle of the vehicle, or both.
- To avoid the possibility of damage so arising, and as shown in Figs. 12 and 13, the improved form for the vehicle incorporates first and second load limiter means 191, 193, respectively associated with the jacking arrangements of the rear trolley of the vehicle.
- The load limiter means 191, 193, which, as shown, are respectively incorporated in the winding handles, as 195, of the jacking arrangements of said rear vehicle trollies, are constituted as torque limiter devices which incorporate friction means adapted to slip in the event that torque applied by the operator at the winding handles, or either of them, exceeds a pre-set value.
- More particularly, and as shown in Fig.16, the winding handles, 195, of each of the rear trollies, are mechanisms each of which comprises: a
basic handle portion 197, aring 199, a bushing 201, afirst bevel gear 203, anaxle 205, asecond bevel gear 207, first and second sets of intercalatedannular friction discs 209, 211, respectively, a torque-settingnut 213, and acover 215. - As may be seen, the
handle portion 197 is secured to thering 199 by a pin. Theaxle 205 is a shaft which is fixed outstanding from a cylinder 217. At this point it is pointed out that the cylinder 217, constitutes part of one or the other of the main frames of the jacking arrangements of the rear trolley of the vehicle, being the cylindrical main frame parts corresponding to that, of the front trolley part, designated by thereference numeral 39 in Fig.1. Thefirst gear 203 has acylindrical stem portion 219 through which theaxle 205 extends, aroller bearing 221 being provided between thestem portion 219 and theaxle 205. - The
gear stem portion 219 extends within the bushing 201, the stem portion and the bushing 201 being pinned together by a means of ascrew connection 223. The bushing 201, in turn, extends through thering 199. - The intercalated
annular friction discs 209, 211 of the first and second sets of such discs are located to the rear of thering 199, being carried, trapped between thering 199 and aspring 225, on the bushing 201 and being held, under pressure exerted by said aspring 225 under the force exerted by thenut 213 which is in threaded engagement with the bushing 201 at its free end. - The threaded
rod 35 of the jacking arrangement extends freely through thecylinder 207 of the jacking arrangement main frame, and is in threaded engagement with thesecond bevel gear 207, the latter gear thereby constituting the nut for driving the threadedrod 35. As previously stated, in relation to the first described embodiment, the nut of the jacking arrangement, that is to say, thegear 207, is constrained with respect to thecylinder 207, the main frame of the jacking arrangement, such that the gear/nut 207 is capable only of rotation about the axis of the threadedrod 25, the rod being thereby longitudinally displaced by rotation of the nut. As may be seen aroller bearing 227 is provided between the upper end of thecylinder 207 and the gear/nut 207. - In operation, with the
torque setting nut 213 set to exert, through thespring 225, a pressure calculated to prevent slippage between theintercalated friction discs 209, 211, below a predetermined load (being a function involving the weight of the store to be captured at the pylon and the mechanical advantage exerted by the jacking arrangement), rotation of thehandle portion 197 gives rise to rotation of thebevel gear 203, and, hence, of the meshingbevel gear 207, with the effect mentioned, viz. longitudinal displacement of the threadedrod 35. - If, as a result of over-winding of the
handle portion 197 by the operator, the possibility of excessive load arises, slippage will occur between theinter-calated friction discs 209, 211, the load being, thereby, limited to a safe value. - Whilst the form and function of the torque limiter has been described in relation to the jacking arrangements of the rear trolley of the vehicle, it will be evident that corresponding means needs be provided in the jacking arrangement of the front trolley of the vehicle, also.
