Definitions

  • the invention relates to an apparatus for removing the ballast of a railway without demounting the track according to the first part of claim 1.
  • the structural parts of a railway are the track comprising rails and sleepers, the ballast layer, the intermediate layer, the insulating layer and the embankment fill.
  • the purpose of the ballast layer is to hold the track in a specified, geometrically right position and the purpose of ballasting is to obtain a track which is accurately positioned in vertical and lateral directions.
  • the ballast layer is commonly made of railway ballast.
  • the mineral aggregate used for the ballast must be hard, weather resistant, wear and impact resistant.
  • Railway ballast should not contain any humus, plant remains or any other impurities which might enhance frost lifting.
  • ballast Although there are strict quality specifications for the ballast, it is obvious that in the course of years there will be deformations due to weathering and soiling which change the geometry of the railway. Freezing contaminations in the ballast cause frostheaves in the railway. For instance, railway level crossings are particularly apt to be damaged by frost and it is the humus and other frost-susceptible material that spoils the ballast. In this case, the ballast must be removed and the ballasting must be done anew to get the track in the right position.
  • ballast To enable reballasting the old ballast layer must be removed and cleaned by sieving for reutilization. If the ballast is of poor quality it is preferably utilized as filling material for the embankment or it is carried away. If used ballast is to be used as filling material for the embankment it would be beneficial that the removed ballast could be conveyed to both sides of the track to facilitate reutilization.
  • Ballast replacement is conventionally performed so that first the track is demounted and put aside after which the old ballast and possibly other structural layers of the railway can be replaced.
  • An apparatus which removes the ballast without demounting the track.
  • this apparatus there is a scraper chain which goes under the track and which scrapes the mineral aggregate of the ballast and transfers it onto a sieve. By means of the sieve, the waste material of the mineral aggregate is separated from the ballast.
  • the ballast is returned under the track and the waste material is carried by a belt-conveyor to one side of the track.
  • the buckets of the scraper chain typically consist of finger-like members which are made of hard metal and which loosen stones from the ballast.
  • the sieve of the apparatus is typically a vibrating sieve.
  • the apparatus is mounted to a chassis which moves on the track and it is generally provided with a mechanism for supporting the track.
  • Said apparatus is originally designed as a ballast washing-machine.
  • the object of the invention is to eliminate above drawbacks and present an apparatus for removing the ballast of a railway without demounting the track which apparatus has a simple structure and versatile operation. This object is obtained by means of an apparatus which is presented in the claim 1.
  • the apparatus comprises an aggregate remover which is operated by such an excavator which is provided with track wheels in addition to conventional wheels or caterpillar tracks. This is advantageous in that the apparatus can be moved both on roads and on railway tracks and, when there is a passing train, the apparatus need not be moved a long way since one can use e.g. the nearest level crossing to move the excavator aside for the time of the passing train.
  • the aggregate remover which is mounted to the boom of the excavator, is pushed by means of said boom into the ballast below the track from one side of the track.
  • the aggregate remover can be pushed under the track without any trenches and it enables removal of the ballast evenly to both sides of the track.
  • One aggregate remover is provided with blade-like transporting members which are wider within their lower portion and which carefully move the ballast aside through sliding so that the sleepers are not damaged.
  • the apparatus according to the invention brings along a considerable saving of time. For instance, it takes only 2-3 hours to change the ballast under a one-track level crossing.
  • the working speed on track is approximately 100 track-m/h and the work requires only a few persons. If necessary, a sieve dipper can be provided in connection with the excavator which then enables one to perform all those stages of operation which are needed in reballasting.
  • the apparatus comprises an excavator 12, having a boom 13 and own wheels, and a mechanism 15 for removing mineral aggregate which hereon will be called the aggregate remover 15.
  • an excavator or the like apparatus which has conventional operational capabilities and which is provided with normal wheels or track chains, serves as the drive mechanism for the aggregate remover 15.
  • the excavator 12 is also provided with track wheels 14, which are made of steel, to move the excavator 12 specifically on the same track whose ballast is being removed. Therefore, the excavator 12 that is used is a normal excavator except that it is provided with track wheels 14 for travel along the track.
  • the aggregate remover 15 is attached to a fast coupling member on the boom 13 of the excavator.
  • a fast coupling member e.g. a sieve dipper can be connected after the ballast removal work by which dipper the ballast removed from beneath the track is cleaned and sieved for reuse.
  • the trajectories of the aggregate remover 15 there are available the same trajectories of motion as there are in a normal operation of the excavator 12. Therefore, it can be moved up, down, forward, backward, left and right, and it can be inclined and rotated at the end of the boom.
  • the aggregate remover 15 gets its power from the hydraulic system of the excavator.
  • the hoses of the hydraulic motor, which serves as the drive unit 7, are connected to the corresponding hydraulic connectors of the excavator 12 i.e. to the hydraulic inlet and outlet connectors whereby operation of the hydraulic motor can be controlled by a valve in the cab of the excavator 12. If it is desired to change the direction of rotation of the hydraulic motor, the flow direction of the hydraulic liquid is changed so that the inlet hose becomes the outlet hose and the outlet hose becomes the inlet hose, respectively.
  • the aggregate remover 15 comprises primarily a body 1 and, in connection with the body 1, an endless circumferential member 2 having transporting members 3 attached thereto.
  • the body 1 is essentially a planar blade or the like, which is designed to be positioned essentially horizontally under the track.
  • the endless circumferential member 2 is disposed on the outer circumference of the body 1.
  • the aggregate remover 15 is pushed into the ballast layer under the track from the side of the track essentially in a horizontal plane and the endless circumferential member 2 is rotated in a plane below the track.
  • Transporting members 3 attached to the endless circumferential member 2 dig into the mineral aggregate of the ballast and transport it from beneath the track to the side thereof.
  • the aggregate remover 15 transports mineral aggregate of the ballast layer from the middle of the track to the side of the track.
  • the aggregate remover 15 can be turned to operate in a similar way on the other side of the track.
  • the endless circumferential member 2 is in the exemplary case a track chain or the like and the transporting member 3 is a blade which projects perpedicularly from the circumferential member 2 and extends vertically. Attached to the circumferential member 2 between the transporting members 3, there are also provided finger-like members 4 made of hard metal which are designed to disintegrate possible ice or very tightly compacted mineral aggregate in the ballast.
  • the lower part 3' of the transporting member 3 is essentially wider than the upper part 3''. This enables the transporting member 3 to dig into the mineral aggregate so that, during rotation of the endless circumferential member 2, the mineral aggregate of the ballast above the lower portion of the transporting member 3' first falls down and then it is transported, pushed by the transporting member 3, to the side of the track. Transporting members 3 transport mineral aggregate from the ballast layer so that the ballast layer slides down in slices along a slide plane specific to used mineral aggregate to be then transported by the transporting members 3. Therefore, the rotating track chain cannot damage the track structure.
  • the circumferential member 2 is arranged to rotate under guidance of a pulley 5 which is mounted in bearings to the body 1 so that the pulley 5 is connected to the drive unit 7 preferably by means of a power transmission assembly 8.
  • a hydraulic motor serves as the drive unit 7 in the exemplary case.
  • the power transmission assembly 8 comprises a planetary gear which is arranged to control the rotational speed of the endless circumferential member 2.
  • the transmission ratio of the planetary gear is so chosen that the speed of the circumferential member 2 i.e. the track chain can be changed within suitable limits.
  • the trajectory of the circumferential member 2 is elongated. This has been achieved so that the circumferential member 2 is arranged to rotate under guidance of a second pulley 6 which is mounted in bearings to the body 1.
  • the second pulley 6 is mounted in bearings to a spring-loaded traveller 10 which traveller 10, in case of overload, is constrained to move along guides 11, which are mounted to the body 1 and which are parallel with the longitudinal direction of the aggregate remover, towards the pulley 5 which is connected to the drive unit 7.
  • This is beneficial in that if it happens that a stone gets between the track chain and the pulley 6 or the pulley 5 the aggregate remover will not be damaged.
  • the body 1 of the aggregate remover 15 is also provided with suspension means 9 which are advantageously placed closer to the pulley 5, which is connected to the drive unit 7, apart from said drive unit 7.
  • the aggregate remover functions in the following way.
  • the hydraulic motor drives the planetary gear which transmits power to the driven pulley and further to the track chain which performs removal of ballast from beneath the track by means of transporting members.
  • the track chain turns around the sheave pulley and back to the driven pulley.
  • the sheave pulley is spring-loaded and it can move in the traveller 10 towards the driven pulley 5.
  • the pulley assembly of the aggregate remover is protected by protective plates which are part of the body and which are placed on both sides of the track chain.
