Definitions
- the present invention concerns a machine for reconditioning railway roadbeds.
- machines for reconditioning railway roadbeds, comprising an equipped wagon provided with means of temporarily lifting the track of the roadbed under the wagon, and excavation means for removing the ballast of the roadbed under the raised track. This removed ballast is conveyed to screening means to be partially recovered and returned to the reconditioned roadbed.
- the excavating means usually fitted with an excavating chain, pass under the sleepers for their entire length.
- the overall width of the excavating chain is somewhat greater, on both sides, than the length of the sleepers and therefore these machines cannot be used where any obstacle, natural or due to construction works, limits the free transverse section of the roadbed, on one or both sides in proximity to the edge of the heads of the sleepers, for example in tunnels, between platforms in stations, on certain bridges and so forth.
- this known machine is not provided with a unit for demolishing the roadbed.
- the object of the present invention is therefore the creation of a machine for reconditioning railway roadbeds which allows the performance of special jobs, such as the lowering of the roadbed which is necessary in some cases inside railway tunnels, including in the presence of any rocky layers lying under the ballast, or other normal material for making the roadbed.
- special jobs such as the lowering of the roadbed which is necessary in some cases inside railway tunnels, including in the presence of any rocky layers lying under the ballast, or other normal material for making the roadbed.
- no. 1 indicates an equipped wagon of the present machine for reconditioning railway roadbeds.
- the wagon 1 comprises at the top a longitudinal beam 2, whose front and rear ends 3 and 4, are supported by corresponding railway axles 5 and 6, or bogies, suitable for running on a track 7 of any railway line.
- This track 7 consists of a pair of rails 8, of which one is visible in the drawing, joined by a series of sleepers 9 suitably positioned and connected to the rails 8 by suitable removable fixing means 58.
- the track 7 rests on a roadbed 10 formed of ballast and/or other suitable material.
- the equipped wagon 1 comprises at its front and rear ends 3 and 4 control cabins 11 and 12.
- the present machine comprises a gripping and lifting device 13 for the rails 8 of the track 7.
- This device 13 for each of the rails 8 comprises for example a pair of lifting rollers or clamps 14 held solid by an arm 15 connected to actuating means 16 for raising and lowering it, for example linear actuators.
- the fixed part of these actuating means 16 is connected to the longitudinal beam 2 of wagon 1.
- To the longitudinal beam 2 is also connected, immediately upline of this lifting device 13 for the rails 8, a unit for demolishing the roadbed, which comprises a row of pneumatic hammers 17 arranged transversely with respect to the track 7.
- a rotatable clamp 18 is shown, suitable for gripping an individual sleeper 9, lifting it, inclining it suitably and taking it back to a new position, as we will see more clearly below in the description of the operation of the present machine.
- This rotatable clamp 18 is connected to an actuator 19 connected at the top to a bogie 20 suitable for running longitudinally inside a box-section support 21 fixed to the longitudinal beam 2 of the wagon 1.
- a motor unit 22 On the longitudinal beam 2 a motor unit 22 is installed which activates a device 23 for excavating and collecting the material of the roadbed 10, which is known per se.
- This device 23 is suitably inclined and comprises an excavating chain, not illustrated, suitable for conveying the material of the roadbed onto a conveyor belt located inside the side-walls of the device.
- This belt conveys the material removed from the roadbed towards a further conveyor belt 47 which will transfer it to a following wagon, not illustrated, provided with screening means for the excavated material, to eliminate reject material and redistribute the cleaned material recovered by screening.
- the excavating device 23 is supported on the beam 2 by means of an oscillation pin 24 and by actuating means 25 which allow the inclination to be varied. All the devices described above and provided for on the wagon 1 are illustrated in Fig. 1 in a non-operating position.
- Fig. 4 illustrates the rotatable clamp 18 in detail.
- This clamp 18 comprises two arms 26 suitable for rotating around a common pin 27 so as to separate and come together to clamp one of the sleepers 9 of Fig. 1 . These arms 26 are controlled by an actuator 28.
- the clamp 18 is connected to a head 29 integral with the movable rod 30 of the actuator 19.
- This rod 30 runs inside a cylinder 31, forming an annular upper part 32 which rests, by means of a thrust bearing 33, on a support 34 fixed at the bottom to the bogie 20.
- This cylinder 31 is capable of rotating around a vertical axis with respect to said support 34 and said bogie 20, and roller bearings 35 are provided for this purpose in said support 34.
- the cylinder 31 is rotated in one direction or the other, and transmits said rotary motion to the arms 26 of the clamp 18, by means of an actuator 36, provided in the bogie 20.
- This actuator 36 (see also Fig. 5 in the attached drawings) comprises a cylinder 37 connected at one end and by a rotation pin 38 to a wall of the bogie 20.
- this cylinder 37 there runs in one direction or the other a rod 30 connected, at one end and by means of a rotation pin 39, to a lever connected to a head 41 of the cylinder projecting into the bogie 20.
- This bogie 20 comprises a series of pairs of wheels 42 by means of which it can run along guides 43 formed in the box-section support 21 fixed to the longitudinal beam 2. At least one pair of such wheels, for example wheels 42', are connected to an activating reduction motor 44.
- Fig. 6 illustrates the unit of the present machine for demolishing the roadbed 10.
- This demolition unit comprises two pneumatic hammers 17 positioned externally to the rails 8 of the track and two pneumatic hammers 17' positioned internally to the rails 8.
- Each of the pneumatic hammers 17 and 17' is controlled by its own lowering and raising actuator, respectively actuators 45 for the external pneumatic hammers 17 and actuators 45' for the internal pneumatic hammers 17'.
- Each of the actuators 45 for the external pneumatic hammers 17 comprises a cylinder 46 fixed, by means of suitable supports, to the longitudinal beam 2 of the wagon, and a movable rod 47 connected to the striking mass 48 of the relative pneumatic hammer 17.
- Each of the actuators 45' for the internal pneumatic hammers 17' comprises a cylinder 46' fixed to a bogie 49 running transversely with respect to the longitudinal direction of advancement of the wagon, which is direction S in Fig. 2 , and to the longitudinal direction of extension of the rails 8.
- This bogie 49 which can be similar for example to the bogie for the rotatable clamp described above, is supported by suitable guides 50 integral with the longitudinal beam 2 of the wagon.
- Fig. 7 illustrates a variant of the demolition unit of the present machine.
- the external pneumatic hammers 17 are identical and operate in the same way with respect to what was previously illustrated in Fig. 6 .
- the internal pneumatic hammers 17' however have the relative striking masses connected to each other by an actuator 52 and each of them is connected at the top to the beam 51 by means of an oscillation pin 57.
- the cylinders 46' of the two actuators 45' are connected directly to the longitudinal beam 2 of the wagon.
- the two internal pneumatic hammers 17' manage to operate on the entire width of the roadbed 10 comprised between the rails 8 as a result of their variable inclination, controlled by actuator 52, and of their being fixed with oscillation pins 57 to beam 51.
- the equipped wagon 1 moves in the direction S of advancement indicated in Fig. 2 .
- the side-walls 59 of the device 23 for excavating and collecting the roadbed material which advantageously have an overall side-to-side dimension which does not exceed the width of the sleepers 9, 9' and 9".
- This drawing also schematically illustrates the rotatable clamp 18, the group of pneumatic hammers 17 arranged parallel to the sleepers, according to any of the two forms of embodiment shown in Figs. 6 or 7 , and the device 13 for gripping and lifting the rails.
- the actuators 16 of the device 13 are lowered in such a way that the means 14 of gripping the rails 8 are clamping the latter. These actuators are then retracted upwards so that the rails are temporarily raised from the released sleepers 9' and 9".
- the sleeper 9 situated at a given moment in the reconditioning process immediately in front of excavating device 23, is grasped by the arms 26 of the rotatable clamp 18, lifted from the roadbed 10 and inclined in a suitable manner so that it can be translated backwards past excavating device 23. Having arrived at its new laying position, in which the bogie 20 of the clamp 18 has travelled backwards substantially over the entire distance permitted by the support 21, the sleeper 9" is counter-inclined so as to make it assume once more the position transverse to the rails 8, and laid in the new position.
- pneumatic hammers 17 and 17' sliding vertically upwards or downwards, penetrate the roadbed for the depth of lowering required.
- These pneumatic hammers 17 also break up any rock present in the roadbed and this broken-up rock is collected by excavating device 23 along with the ballast from the roadbed.
- the part of roadbed 10' situated upline of excavating device 23 (again, see Fig. 2 ) is lowered by the height required and reconditioned, and therefore the sleepers 9 in that part can be refixed to the rails 8.
- all the material collected by the excavating device 23 will be transferred by the conveyor belt 47 to screening means provided on a wagon following wagon 1 where the present reconditioning machine is positioned.
