Definitions

• the present invention relates to a fixing device of a crossbeam, which serves to seat the rails of a railway track on it, for a track without a ballast.
• the concrete plate tracks withstand increasing mechanical stresses that derive from the increasing pressure of the axles of the vehicles and the speeds of the same that tend to increase in recent times.
• the life time of the deformable body must be increased, preventing the concrete sleepers from sliding laterally on the concrete base plate if a too flexible interplate is located under the sleeper.
• the present invention seeks to solve one or more of the drawbacks set forth above by means of a fixing device of a sleeper body for a plate track as defined in the claims.
• a fastener device of a sleeper to a base plate of a plate track where an interplate is located between the sleeper body and the base plate according to an overlapping layer configuration; where the sleeper body comprises at least one through hole; the base plate comprises at least one blind hole in which a securing block is recessed; the fixing device is insertable in the through hole to be detachably immobilized by the securing block in the installation position of the plate track; without subjecting the plate to an additional claim to which the plate is subjected when the cross member is placed on the base plate.
• the block is firmly locked and prevented from moving inside the corresponding blind hole.
• the fixing device comprises a guide rod for positioning the cross member on the base plate in the installation position of the plate track; and an immobilizer end that mechanically collaborates with the fastener block to fix the cross member in the installation position of the plate track.
• the rod and end of the fixing device pass through the interplate.
• the fixing device also comprises a head included in the through hole without protruding from the upper plane of the cross member in the installation position of the plate track.
• the guide rod is inserted into a sleeve that internally lines the through hole in the position of the plate track.
• the immobilizer end is threadable on an internal thread of the securing block such as a tightening and retaining nut, in the installation position of the plate track.
• the inner diameter of the sleeve of the through hole is larger than the diameter of the rod of the fixing device, which allows the through hole to be aligned with the securing block to ensure the focused attack of the force of the fixing device on the fixing block. In this way, the fixing device is requested exclusively in the direction of traction and a twisting thereof is avoided.
• the head of the fixing device has a diameter substantially equal to the diameter of the sleeve of the through hole, whereby the head is locked and immobilized to make small lateral displacements according to a diameter of the head inside the jacket of the through hole, but allows limited vertical displacements of the shirt with respect to the head and stem of the fixing device in the installation position of the track in license plate.
• the body of the sleeper comprises at least two through holes arranged in proximity to each free outer side; that is, the sleepers are arranged in a row one after the previous one on the interplate.
• the through holes may be arranged along an inclined axis with respect to an axis parallel to an edge of a free outer side of the sleeper body; for example, the inclined axis cuts obliquely to two non-contiguous vertices of the sleeper body.
• the sleeper body comprises at least two rail track retaining means intended for the retention of the rails on the reinforced concrete sleeper body.
• the retention means are embedded in corresponding emptyings of the cross member from the upper plane to the lower plane thereof.
• the rail retention means are also aligned in a row.
• the interplate is made of elastic material such as an elastomer, being arranged between the crossbar and the base plate in a layered or sandwich configuration, so that the cross-sectional body exerts an original claim, function of the weight thereof, and the Fixing arrangement, when fixing the sleeper body on the base plate in the installation position of the track, does not increase the original claim of the sleeper body. That is, the naughty body exerts additional pressure on the original claim to the passage of a train car.
• the sleeper body describes a sliding vertical movement, limited elastic travel, from a rest position, corresponding to the installation position of the plate track, to a working position, relative to the passage of a train car over the rail tracks, and vice versa. That is to say, the time that the naughty body is in working position is a function of the frequency of trains passing through the railroad.
• the fixing device provides an elastic, resistant and economical fixation or retention to the sleeper, which requires a small number of parts and whose assembly is simple and precise workmanship without specialization.
• the fixing arrangement provides an elastic retention whose elasticity is due to both the nature of the interplate and the sliding retention system of the sleeper body in the installation position of the plate track.
• the sleeper is firmly retained and, at the same time, the elastic retention results.
• the plate track comprises at least a portion of the base plate, an interplate and at least one sleeper body installed in a configuration in superimposed layers fixed in the installation position of the plate track by means of the fixing device.
• the plate track comprises parts without movement such as the base plate and the fixing device, and animated parts of reduced amplitude movement such as the interplate and the cross member body.
• Figure 1 shows in an elevation view a plate track in an overlapping layer configuration, from below upwards, base plate, interplate, sleeper body, rail track
• figure 2 shows in a profile view a fixing device in the installation position of the plate track
• figure 3 shows in a perspective view of the plate track where the fixing device has been disassembled to remove the cross member from the installation position of the plate track
• figure 4 shows in a plan view the plate track in the installation position.
• a plate path which includes, in an arrangement in vertical or sandwich layers, a base or seat plate 18, bottom layer, an elastic interplate 15, intermediate layer, a crossbeam 13 longitudinally along the longitudinal axis of a rail 19 of the railroad track, and a crossbar fixing device 11, which anchors it to the base plate 18 of the railroad track.
• the sleeper body 13 comprises at least one through hole 12 lined internally by a jacket.
• the base plate 18 comprises at least one blind hole 16 in which a securing block 17 is embedded, so that the securing block 17 is firmly locked and prevented from moving inside the blind hole 16.
• the fixing device 11 is inserted into the sleeve of the through hole 12; the fixing device 11 being detachable in a detachable manner by the securing block 17 in the installation position of the plate track. Therefore, the interplate 15 is not subject to an additional claim in the installation position of the plate track; that is, the interlayer 15 is subjected to an origin claim based on the weight of the body of the cross member 13 when it is arranged above the interlayer 15, which is, in turn, arranged on the base plate 18.
• the fixing device 11 comprises a guide rod 22 for positioning the crossbar 13 on the base plate 18 in the installation position of the plate track; and an immobilizer end 23 that mechanically collaborates with the securing block 17 to fix the crossbar 13 in the installation position of the plate track.
• the fixing device 11 also comprises a head 21 included in the through hole 12 without protruding from the upper plane of the crossbar 13 in the installation position of the plate track.
• the guide rod 22 is insertable into the sleeve that internally lines the through hole 12 in the installation position of the plate track.
• the immobilizer end 23 is threadable on an internal thread of the securing block 17 such as a tightening and retaining nut, in the installation position of the plate track.
• the inner diameter of the sleeve of the through hole 12 is larger than the diameter of the guide rod 22, which allows the through hole 12 to be aligned with the securing block 17.
• the head 21 of the fixing device 11 has a diameter substantially equal to the diameter of the sleeve of the through hole 12, whereby the head 21 is held and immobilized within the sleeve of the through hole 12 in the installation position of the track on plate.
• the cross member 13 comprises at least two through holes 12 arranged in proximity to each free outer side thereof; that is, the sleepers 13 are arranged in a row one after the previous one on the interplate. Therefore, the right and left outer side of the row are free.
• the through holes 12 may be arranged along an inclined axis with respect to an axis parallel to an edge of a free outer side of the cross member 13; for example, the inclined axis cuts obliquely to two non-contiguous vertices of the crossbar 13.
• the crossbar 13 comprises at least two rail track 19 retaining means intended for the retention of the rails 19 on the reinforced concrete crossbar 13.
• the retaining means are embedded in corresponding drains of the cross member 13 from the upper plane to the lower plane thereof.
• the track retention means are also aligned in a row.
• the interplate 15 is made of elastic material such as an elastomer, being arranged between the crossbar 13 and the base plate 18 in a layered or sandwich configuration, so that the crosspiece exerts an original claim, function of the weight thereof and the Fixing arrangement 11, when fixing the crossbar 13 on the base plate 18 in the installation position of the plate track, does not increase the origin claim of the crossbar 13. That is, the crossbar 13 exerts an additional pressure on the origin claim to the passage of a train car. Consequently, the cross member 13 describes a vertical sliding movement from a rest position, corresponding to the installation position of the plate track, to a working position, relative to the passage of a train car on the rail tracks 19, and vice versa. That is, the time that the Naughty 13 is in working position is a function of the frequency of trains passing by rail.
• the fixing device 11 provides an elastic, resistant and economical fixation or retention to the cross member 13, which requires a small number of parts and whose assembly is simple and precise workmanship without specialization.
• the fixing arrangement 11 provides an elastic retention whose elasticity is due both to the nature of the interplate 15 and to the sliding retention system of the cross member 13 in the installation position of the plate track.
• the cross member 13 is firmly retained and, at the same time, the elastic retention results.
• the plate track comprises at least a portion of the base plate 18, an interplate 15 and at least one crossbar 13 installed in a configuration in overlapping layers fixed in the installation position of the plate track by means of the fixing device 11.
• the track in plate includes pieces without movement such as the base plate 18 and the fixing device 11, and animated parts of reduced amplitude movement such as the interlayer 15 and the crossbar 13.
• the regulation of the amplitude of the vertical displacement can be carried out by increasing the thickness or width of the interlayer layer 15.
• the cross member 13 is laterally removable in case of failure of the base plate seat 18, for example.
