MACHINE AND METHOD FOR RAILWAY TRACK MAINTENANCE, FOR TRACK LEVELLING, ALIGNMENT, COMPACTION AND STABILISATION, CAPABLE OF OPERATING WITHOUT INTERRUPTING THE FORWARD MOVEMENT THEREOF

摘要

The invention refers to a machine and a method used to level, align and stabilise the track and compact the ballast bed, producing controlled lifting, so that the load used in the settlement of the rail in its theoretical position falls within the established range, working in an uninterrupted manner. The machine is constituted by two bogies with traction capacity, and front, back and centre control cabins and a rear and frontal measuring tensioner trolleys. The machine has an additional lifting unit whose relative movement with the rest of the machine in controlled by total longitudinal cylinder. The alignment cylinders generate a transversal movement to cause track alignment. Behind this unit according to the direction of work a stabilising unit is situated which consists of two stabilising trolleys. The ground-penetrating radar is situated at the machine front.

1. Railway maintenance machine for track levelling, alignment, compaction and stabilisation, with the capacity to operate without interruptions to its advance, characterised by its constituting the following elements, according to the direction of work:
A ground-penetrating radar placed to capture the degree of compaction of the area of ballast bed below it. An additional lifting unit with the capacity to position and pack the track into the required position, which in turn is composed of: A lifting and alignment trolley equipped with rollers, which latch onto the railhead through the use of a series of actuations, and with means of displacement in the longitudinal direction of the track. A series of actuators which are articulated and connected to fixed points on the machine's chassis and the lifting and alignment trolley, used to move the track into the required position in both a vertical and horizontal direction to its transversal plane. A compacting trolley equipped with wedge-shaped bodies. A series of actuators, articulated to fixed points of the machine's chassis and the compacting trolley, used to displace the wedge-shaped bodies over the ballast bed and also to apply a vertical load to the same. An actuator situated on the frame of the compacting trolley, equipped with eccentric rotatory bodies which generate an oscillating component in the load applied to the ballast bed. A series of actuators for relative longitudinal movement between the lifting and alignment trolley and the compacting trolley. A series of actuators for relative longitudinal movement between the additional lifting unit and the machine's chassis. A stabilising unit equipped with the means to settle the track into the required position. A system to measure the geometric parameters of the track, comprised of five measuring trolleys situated in the following manner; the first at the front of the machine, in front of the ground-penetrating radar. The second between the lifting and alignment trolley and the compacting trolley. The third between the two trolleys of the stabilising unit. The fourth behind the stabilising trolley, in front of the rear bogie. The last is situated behind the rear bogie.
