Rail fastening device
A rail fastening device (100) comprises a lower plate (11) and an upper plate (12) provided with a pair of clips (13) for engaging the rail 16, the upper plate (12) being fastened to the lower plate (11) by a pair of fastening bolts (19) which extend through respective apertures (20) in the upper plate (12), the fastening bolts (19) being slidably mounted to the lower plate (11) for movement in a direction which, in use, extends transverse the rail (16). A jacking bolt (31) is arranged to lift the upper plate away from the lower plate as the bolt (31) is tightened and vice-versa. An alignment bolt extends 33 laterally between the upper and lower plates (11), (12) and is rotatable to displace the upper plate (12) laterally relative to the lower plate (11). A levelling bolt (102) threadably engaged with the lower plate is arranged to lift the lower plate (11) away from the surface on which the device (100) is seated as the bolt (102) is tightened and vice-versa.
Screwing machine
A screwing machine tightens or releases rail fixing screws. The screwing machine contains a machine frame which can be rolled on a track, handles for moving the screwing machine, a motor for applying a torque to a screw head, and a device for transmitting a torque. A measuring device is provided opposite the machine frame in order to detect a reaction torque of the motor. The motor is actuated in order to limit the torque depending on the reaction torque. The reaction torque is used as a reference variable. The reaction torque is applied to the machine frame by the motor and is ascertainable with a high degree of precision by a simple measuring device. In this manner, a simple and robust design and a precise rotational speed limiting function are implemented.
Rail joint assembly having forged rail joint bars
A rail joint bar includes a body having a first end, a second end positioned opposite from the first end, a first side, a second side positioned opposite from the first side, a top portion positioned between the first and second sides, and a bottom portion positioned between the first and second sides and positioned opposite from the top portion. The body having a first section adjacent to the first end of the body, a second section adjacent to the second end of the body, and an intermediate section positioned between the first section and the second section. The second side of the body includes a first protrusion and a second protrusion spaced from the first protrusion, with a width of the first protrusion at the intermediate section of the body larger than a width of the first protrusion at the first and second sections of the body.
ROLLING VEHICLE TRACK
A rolling vehicle track including a first wall and a second wall each positioned between and connected to a third wall and a fourth wall. The track further includes a bracket having a first bracket portion, a second bracket portion, a third bracket portion, and a fourth bracket portion, the first bracket portion connected to the third wall, and the fourth bracket portion connected to the first wall. The track further includes the first wall, the second wall, the third wall, and the fourth wall defining a first quadrilateral chamber. The track further includes the first bracket portion, the second bracket portion, the third bracket portion, and the first wall defining a second quadrilateral chamber, the first wall, the second wall, the third wall, the fourth wall, and the bracket are interconnected without welding.
AN ANCHORING ASSEMBLY FOR FASTENING A RAILWAY RAIL TO AN UNDERLYING FOUNDATION
An anchoring assembly for fastening a railway rail to an underlying foundation, the anchoring assembly including a base plate configured to receive the rail, a fastener configured to fasten the base plate to the underlying foundation, and a rigid sleeve defining a passage through which a stem of the fastener passes. The base plate comprises an opening and the sleeve is configured to extend through the base plate opening, the sleeve extends a distance greater than a thickness of the base plate such that the sleeve extends from a top surface of the base plate and beyond a bottom surface of the base plate when installed, and the sleeve is configured such that a compressive load applied by the fastener when installed is transmitted through the sleeve to the underlying foundation.
Rail Fastening System
A rail fastening system for fastening a rail on a subsurface, preferably a ballastless track, comprises at least one retaining element for mounting the rail on the subsurface. The retaining element has an angle guide plate that, in the assembled state, is configured to divert transverse forces from the rail into the subsurface and a shoulder part that, in the assembled state, is configured to butt together with the angle guide plate and to lie in a recess of the subsurface in a positive-locking manner.
RAILROAD TIE PLATING MACHINE AND METHOD
A plating system for attaching a pair of tie plates to a wooden railroad tie with screw spikes such that the tie plates are aligned and in gauge. A predrilling system is used to predrill holes in the appropriate position on the railroad tie according to the line end of the tie prior to loading the tie into the plating system. The plating system clamps the railroad tie in registration according to the line end of the tie, and holds the tie plates in the appropriate position while a pair of hydraulic screw-presses turn screw spikes to fasten the tie plates to the railroad tie in gauge, centered and aligned on the railroad tie.
NAIL PUNCHING MACHINE FOR DRIVING IN OR PULLING OUT RAIL SPIKES OF A RAIL TRACK
A nail punching machine for driving in or pulling out rail spikes comprises a driving mechanism, which is driven by means of an electric drive motor. The electric drive motor is supplied with electric power by means of an accumulator. The nail punching machine is held by an operator by means of at least one handle.
