Definitions

  • This invention relates to a method and an apparatus for removing ballast from a road bed, and to an apparatus and method for maintaining such apparatus and, more particularly, to an improved method and apparatus for removing ballast from a rail road bed.
  • FIG. 1-3 an apparatus for removing ballast from a road way, particularly from a rail road bed.
  • the apparatus is incorporated into a vehicle 1 which is intended to be driven and controlled by a single operator thereby overcoming the labour intensive problems associated with the prior art methods and apparatus used.
  • an apparatus for removing ballast comprises a vehicle 1 provided with suitable transport means 2.
  • the vehicle comprises a main frame 3 to which the transport means 2 for advancing the vehicle along a road bed are connected in a conventional manner.
  • transport means 2 includes caterpillar tracks 4 mounted on either side of the vehicle and this provides adhesion to the ground for the apparatus to penetrate the ballast and these allow the vehicle to be driven directly over rough or uneven ground in order to gain access to the road way to be worked on.
  • the apparatus further comprises means for excavating and lifting ballast from the rail bed.
  • the excavation means 5 is mounted on the front of the main frame 3 of the vehicle (as determined by the direction of operation of the vehicle) and comprises a loading apron 6 which may be formed of a wear resistant material.
  • the loading apron comprises a generally C-shaped member which is mounted to the main frame at the closed end thereof.
  • Means are provided on the main frame 3 for raising and lowering the loading apron 6 towards and away from the rail bed and also for altering the transverse relationship with the main frame. This allows the position of the loading apron to be adjusted in order to ensure that the loading apron maintains the optimum position during operation.
  • Feeding means are provided within the loading apron 6 to encourage ballast excavated and lifted by the loading apron to pass through it back towards the main frame 3 of the vehicle.
  • the feeding means in the illustrated embodiment comprise a pair of rotors 8 which are mounted side by side within the loading apron and a set of spill plates 7.
  • the rotors are each provided with a plurality of blades 9 which may be formed of a wear resistant material.
  • the blades are of a sufficient length as to advance ballast towards the centre of the loading apron.
  • Means comprising motors located beneath the apron are provided for rotating the rotors 8 in opposite directions to facilitate advancement of the ballast.
  • Conveyor means are provided within the main frame 3 of the vehicle for conveying ballast from the loading apron 6 to the rear of the vehicle.
  • the conveyor means may be in the form of a conveyor belt 10.
  • the height of the conveyor belt increases as it passes through the vehicle 1.
  • Means (not shown) may be provided on the main frame to adjust the height of the conveyor belt 10 if required. It is envisaged that the conveyor belt will be driven by hydraulic means provided on the main frame. Additionally, tensioning means may be provided in order to adjust the tensioning of the conveyor belt to achieve optimum operation of the apparatus.
  • a selectively positionable feeding means is mounted to the rear of the vehicle.
  • the feeding means takes the form of a boom member 11 mounted onto the main frame 3 by suitable fixings which allow the position of the boom 11 to be adjusted as required.
  • the boom member is provided with a further conveyor belt 12 which extends along the entire length of the boom.
  • this secondary conveyor belt may be provided with tensioning means to adjust the operational characteristics of the belt.
  • a control cab 13 is mounted on the main frame 3 of the vehicle and in the illustrated embodiment is shown as being located behind the loading apron 6 and above the primary conveyor belt 10. It is envisaged that the cab will be fully glazed in order to provide maximum visibility for the operator during use. Furthermore, the position of the cab allows the operator to oversee the operation of the apparatus in order that he can make any adjustments necessary during the excavation process.
  • Control means are provided within the cab, as will be described further below, for operating the vehicle.
  • Such control means may, for example, comprise amongst other things, means for operating and controlling the speed of the primary and secondary conveyor belts 10, 12, control means for raising and lowering the loading apron 6, control means for advancing, retracting and tilting the loading apron and control means for adjusting the position of the boom 11.
  • standard vehicle control means will also be provided within the cab which will allow the vehicle to be driven along standard roads to any particular location where it may be required.
  • a wagon 14 is illustrated in the figures for collecting ballast excavated from the rail bed by the apparatus described above.
  • the wagon is shown as being provided on an adjacent rail to the rail bed being cleared, although the wagon could of course be replaced with a skip or truck which can be moved along the rail bed together with the excavation apparatus in order to facilitate continuous operation of the apparatus.
  • Additional control means for the various components of the apparatus may also be mounted on the main frame 3 of the vehicle. This may include for example, power packs, fuel tank, electric and hydraulic equipment, service jacks and other associated means.
  • the rails of the railroad bed from which the ballast is to be excavated are removed and stored at a suitable location such as adjacent to the rail bed.
  • the removal apparatus as described above is then moved into position on the rail bed.
  • the vehicle 1 upon which the apparatus is located may be driven to the required location or may alternatively be transported to the required location via the existing rail network prior to removal of the rails.
  • Wagons 14 or other suitable collection means is then provided adjacent to the collection apparatus and it is intended that the collection apparatus should be advanced together with the apparatus. It is therefore preferable that a wagon or wagon train be positioned on adjacent tracks to the rail bed to be removed to allow the apparatus to deposit collected ballast into the successive wagons.
  • the position of the boom 11 is adjusted so that the free end of the boom and the conveyor belt 12 provided thereon is located above the wagon 14 or truck into which the excavated ballast is to be loaded.
  • the position of the loading apron 6 of the apparatus can be adjusted, grading down into the ballast in order to bring the front of the loading apron into engagement beneath ballast to be removed.
  • the loading apron 6 and primary and secondary conveyor belts 10, 12 are activated by the operator of the apparatus. As the vehicle 1 is advanced forwards along the rail bed, ballast is lifted into the loading apron.
  • Contra rotation of the two rotors 8 directs excavated ballast between the blades 9 and moves the ballast through the loading apron 6 onto the end of the primary conveyor belt 10 which is located within the loading apron.
  • the excavated ballast is then carried along the primary conveyor belt until it reaches the end of the belt at the rear of the main frame 3. It then falls from the end of the primary conveyor belt and drops onto the secondary conveyor belt 12 provided on the boom member 11 at the rear of the main frame.
  • the ballast is carried along the secondary conveyor belt and falls from the free end of the conveyor belt into the wagon 14 or other collection means provided adjacent to the rail bed.
  • any inconsistencies in the distance between the vehicle and the adjacent collection means can be compensated for by suitable movement of the boom member.
  • Indicator means may be provided within the cab 13 of the vehicle to allow the operator to monitor the position of the boom and to allow him to make suitable adjustments without interrupting the operation of the apparatus. This enables the apparatus to be operated more efficiently and facilitates the one-pass operation of the apparatus as previously described.
  • a wagon train is provided adjacent to the rail bed from which ballast is to be removed.
  • the apparatus can be driven along the rail bed excavating ballast as it advances.
  • the ballast falling from the secondary conveyor belt fills each successive wagon as the apparatus advances along the bed. Once all of the wagons are filled they can be simply transported along the rail track to a suitable location for unloading.
  • the rotors 8 are driven by motors located beneath the apron 6.
  • the motors are operating in a harsh environment where ballast not loaded onto the apron 6 will scrape against the motors. Consequently extensive reinforcement has to be provided to protect the motors.
  • the angle of attack of the apron has to be high enough to allow for the location of the motors to be clear of the ground when the apron is being lowered into engagement with the ground. This can result in the apron being more prone to digging in to the ground and this force has to be resisted by considerable forces being applied to the equipment.
  • the present invention includes any combination of the herein referred to features or limitations.
  • Each motor housing 20 is connected to a back plate 22 of the apron by a pair of arms 24 that diverge outwardly and rearwardly towards the back plate.
  • the rotors 8 are connected to a drive shaft (not shown) that extends from the motor to the motor housing.
  • the motor housings, and therefore the rotors 8 are moved about a horizontal axis defined by pivot mountings 26 at the rear of each arm 24.
  • the arms are raised and lowered by pneumatic or hydraulic pistons (not shown) and each rotor may be raised or lowered separately from each other.
  • the complete motor housing and rotor can be removed from the arms 24 and replaced by a spare unit at the work site, if desired. This minimises down time for the machine which is of particular importance when rail ballast is being removed.
  • any of the parts such as the rotor 8, the blades 9 or the motor within the housing can be separately replaced, as desired. All of this can occur with the apron resting on the ground.
  • the apron 6 is moved from the contracted position to the extended position by an hydraulic ram or rams (not shown) urging the spill plates 7 at each side outwardly with that movement being guided by arms connected to each plate 7 sliding through spaced guides fixed to the underside of the apron 6. These are not shown in the drawings.
  • an hydraulic ram or rams (not shown) urging the spill plates 7 at each side outwardly with that movement being guided by arms connected to each plate 7 sliding through spaced guides fixed to the underside of the apron 6.
  • the rotors may be arranged to move outwardly and inwardly with the spill plates such as by mounting the arms 24 on the spill plates.
  • the rotors may be arranged to move outwardly and rearwardly, with respect to the leading edge of the apron when the spill plates move outwardly, possibly at the same time that the spill plates move outwardly. This may be achieved by connection of one arm 24 to the spill plate with the other being connected to the back plate such that each connection of the arm may be about an upwardly extending pivot. In order to achieve lifting of the rotors the connection of each arm in this embodiment may be a universal axis.
