Abstract
Description
- This invention relates to a machine able to simplify and accelerate the operations involved in picking-up and laying rail switches and track sections generally, it being particularly suitable for small and medium sized firms.
- For said operations, units are known comprising at least two identical machines self-propelled on rails and used together along a railway line, they each comprising a portal structure with its uprights and cross-member of telescopic type, said portal being disposed transversely to the rail track in order to lift a section thereof and shift it laterally stepwise by means of two pivotally-mounted hooks situated below said cross-member. The use of said known machines has shown them to be deficient in terms of stability and safety, and to be limited operationally in that they are unable to abut the track section against the preexisting track. Said deficiencies are due to the fact that the plane portal structure has only one pair of telescopic feet, and for this reason the stability of the entire operational unit relies on the actual track section to be handled, this connecting together said at least two machines by being clamped tightly by them.
- In view of the considerable weight and dimensions of track sections and rail switches, and the type of ground on which said machines have to operate, the considerable risks deriving from said stability deficiency are immediately apparent, in terms of operator safety and the danger of damage both to the rail switches themselves and to the machines which handle them. This also makes it impossible to enable known machines to undergo the longitudinal movement required for abutting the track sections together, this having been done up to the present time by using auxiliary equipment such as hydraulic jacks and the like, which makes the operation difficult, lengthy and complicated.
- The present patent provides and protects a machine which is able to obviate the aforesaid within the framework of a simple and rational construction.
- According to the invention as it is defined in claim 1 the proposed machine is of the aforesaid type, ie of adjustable height and grippage width, and is arranged to operate at least in a pair with a further similar machine, it being designed to lie transversely to a railway line, towards which its two pivotally-mounted lifting hooks point. It comprises a frame of elongated shape at the corners of which there are disposed telescopic feet, and along the longitudinal members of which there is slidably mounted a pair of sliders of variable distance apart which, by means of carriages transversely slidable relative to the sliders, support the pivotally-mounted hooks which grip the rails, the distance apart of these hooks being adjustable by moving one slider relative to the other.
- By virtue of the aforesaid construction details, all the objects of the invention are attained in that the provision of four feet ensures the necessary stability to the machine, and the two mutually orthogonal movements which the hooks can undergo enable a track section to be shifted laterally and inserted with the necessary accuracy between two pre-existing sections.
- In particular, the provision of said two transverse carriages is advantageous for said accurate insertion, as they enable the track section to be shifted longitudinally after having disposed it in correspondance with the sections to be joined up.
- According to the invention, said pair of sliders of variable distance apart is arranged to support a platform for the operator and for the service equipment required for producing and controlling the various machine movements, said platform being able to slide along the machine frame under the control of a hydraulic cylinder-piston unit.
- In addition, said platform is supplied with two pairs of flanged wheels which are able to be swivelled so that they can be disposed either to the side of the longitudinal members or below these latter to enable the machine to be transferred under international clearance gauge conditions, and to lock the rail switch against the grippers and permit the machine to be levelled.
- The constructional characteristics and merits of the invention will be more apparent from the detailed description given hereinafter with reference to the figures of the accompanying drawings in which:
- Figure 1 is an overall perspective view of the invention;
- Figure 2 is a partly sectional view of the invention from above;
- Figure 3 is a section on the line III-III of Figure 2;
- Figure 4 is a secton on the line IV-IV of Figure 3;
- Figure 5 is a diagrammatic view from above showing a rail switch across which three machines according to the invention are disposed.
- From said figures it can be seen that the machine in question is overall of portal configuration (Figure 1) so as to be able to be disposed transversely to a section of a railway line such as the switch 1 shown in Figure 5, or the trbck section indicated by 2 in Figures 3 and 4.
- The cross structure of said portal comprises a
rectangular frame 3 of elongated shape (Figures 1, 2), to the outside of its longitudinal members there being fixed two robusttubular members 4, in each of which twotubular bars 5 are slidingly housed. - These latter are controlled by respective coaxial hydraulic cylinder-
piston units 6 which are fixed to the interior of thetubular members 4 as shown in Figures 2 and 4. To the outer end of eachbar 5 there is fixed a telescopic foot or upright comprising an upperhollow column 7 which slidingly houses alower shank 8 provided with a support plate 9 (Figure 1). - Said
shank 8 is controlled by a coaxial hydraulic cylinder-piston unit 10 which is housed in thecolumn 7 as shown in Figure 3, and the twoopposing columns 7 of each pair are connected together by suitable stiffening elements 11 (Figures 1, 4). - With reference to Figure 2, it will be seen that the length of the
tubular members 4 is less than the length of therectangular frame 3, in order to form four recesses for receiving thecolumns 7 when in their withdrawn position. - This enables the invention to be kept within the allowable transverse dimensions for its transfer along a railway line, for said transfer there being provided external to each tubular member 4 a pair of
flanged wheels 12, each fixed on to an axle 13 (Figure 1), one of which is driven by a hydraulic geared motor, not shown. - Each axle 13 (see Figure 4) is supported by two
arms 14 branching from ashaft 15 which is rotatably mounted on a descendingwall 16 pertaining to a slidingplatform 17 disposed to centrally embrace theelements levers 18, eachshaft 15 is caused to swivel by two hydraulic cylinder-piston units 19 hinged to theplatform 17 below the frame 3 (Figure 4). In this manner, thewheels 12 can be disposed either in a working position or in a rest position, these being indicated by continuous lines and dashed and dotted lines respectively in Figure 4. - To that cross-member of the
frame 3 which in Figures 2 and 3 is situated on the right hand side there are hinged two opposing hydraulic cylinder-piston units 20, which are connected to theplatform 17 so as to cause it to undergo longitudinal movement along said frame. - For the purposes of said movement, the
platform 17 is lowerly provided, on the same side as saidunits 20, with a carriage comprising twovertical end walls 21 connected together by acentral cross-member 22, and provided upperly with a pair ofwheels 23 and lowerly with a pair of rollers 24 (Figure 4). Theelements rectangular frame 3. Afurther carriage 25 also provided withupper rollers 230 and lower rollers 240 (Figures 2, 3) is fixed to the saidplatform 17 in an intermediate position. - In addition, at the opposite end of the platform 17 a third carriage is provided identical with the described
carriage plates 21, the left hand carriage 21-24 is connected to the platform by way of a hydraulic cylinder-piston unit 26 which lies between saidplatform 17 andframe 3, and is parallel to the longitudinal members of this latter. - On the
cross-member 22 of each carriage 21-24, there is slidingly mounted a trolley comprising achannel member 27 which is mounted from below over said cross-member, and is upperly provided with a pair ofrollers 28 disposed in contact with saidcross-member 22. Eachtrolley piston unit 29 disposed above thecross-member 22, and hinged to one of theend plates 21 of this latter (Figures 2, 4). - Transversely to each
trolley lifting hook 30 having anupper lever 31, this latter being caused to swivel by a hydraulic cylinder-piston unit 32 which is hinged to saidtrolley - Finally, as shown in Figures 1 and 2, a
motor unit 34 for driving the hydraulic service pumps, ahydraulic oil tank 35 and a control andmonitoring console 36 are disposed on theplatform 17. - With reference to Figure 5, it can be seen that the machine in question is arranged to operate together with at least one other identical machine, the number of these latter machines depending obviously on the weight and dimensions of the structure 1 or 2 to be handled and/or laid.
- As stated in the introduction, a rail switch 1 or a track section 2 is handled in known manner by laterally shifting said structure 1 or 2 through successive steps, this being done by lifting it, shifting it to one side of the
frame 3, then resting it on the ground, then moving theframe 3 in the same direction with thefeet feet - It should be noted that the invention attains all the stated objects in that its stability is ensured by the four
telescopic uprights hooks 30 allows simple and accurate laying of a track section 2 or rail switch 1, as stated in the introduction. - In particular, said laying accuracy is made possible by the fact that the
hooks 30 are advantageously able to slide in a direction parallel to the railway line above which the machine of the invention lies.
