Description

Rerailer for railway maintenance

Technical Field

The invention relates to the technical field of railway auxiliary equipment, in particular to a re-railing device for railway maintenance.

Background

Railway transportation is one of main transportation modes across regions, and occupies an irreplaceable important position in the world freight transportation and passenger transportation markets, but when the derailed locomotive runs on a steel rail at a high speed, the phenomenon of locomotive derailment occasionally occurs, so a special tool, namely a rerailer, for helping the derailed locomotive to be restored on the steel rail appears, wherein the herringbone rerailer is widely used due to simple structure and convenient use.

However, when the existing herringbone rerailer is installed and used, the traditional herringbone rerailer is only clamped on a steel rail and a sleeper, so that the installed state of the traditional herringbone rerailer is loose, and the phenomenon of deflection is easily caused in the process of rerailing a locomotive to guide the locomotive to reset on the steel rail, so that the extrusion abrasion of a guide bulge on the rerailer is serious, and further the phenomenon of secondary derailment is caused because the guide bulge is excessively abraded in the process of long-term use of the rerailer, and a steel wheel cannot be accurately guided into the steel rail.

Wherein, to laminating utricule I15, laminating utricule II 17 and the setting of transmission structure on it for this rerailer can be stable firm joint on the rail, causes its in-process of working can not take place the phenomenon of incline because of the extrusion that receives the locomotive, and then causes the phenomenon of the protruding excessive wearing and tearing of guide above that.

Wherein, the inner wall of the inner mounting groove 9 is designed into a convex structure, and the bottom ends of the inner groove 16 and the movable pressing plate 10 are designed into arc-shaped curved surface structures which are jointed with the jointing capsule body II 17 and the inner groove 16.

Among this technical scheme, be linked together between the inside of laminating utricule I15 and laminating utricule II 17, and all pack at its inside and have shear thickening liquid.

Wherein, laminating utricule I15 and laminating utricule II 17 adopt wear-resisting elastic rubber material when form to strengthen its and the laminating degree between the rail both sides, and prolong its life.

Wherein, to the setting of shearing thickening liquid among laminating utricule I15 and the laminating utricule II 17 inner chamber, make it change solid-like in the extrusion process that receives movable pressing plate 10, and then increase the joint strength between this rerailer and the rail.

Among this technical scheme, a set of guide groove I4 has been seted up respectively at the middle part on rerailer 1 top, guide groove II 5 and guide groove III 6, guide groove I4 is the curvilinear figure structure along the protruding I2's of guide orbit, guide groove III 6 is the curvilinear figure structure along the protruding II 3's of guide orbit, and parallel and lie in the plane on one side of the rail between the orbit of guide groove II 5 and the rail, guide groove I4 simultaneously, assemble between II 5 and the one end of guide groove III 6 mutually.

The guide grooves I4 and the guide grooves III 6 are arranged to provide a moving space for the protrusions at the edges of the steel wheels so as to guide the steel wheels into the steel rails accurately;

meanwhile, the guide groove II 5 is arranged so as to guide the subsequent derailed locomotive steel wheel, so that the rerailer cannot influence the normal running of the subsequent locomotive after resetting the derailed locomotive, and the reset is not required to be removed in time after the use is finished so as to prevent the rerailer from influencing the running of the subsequent locomotive.

In this technical scheme, the both sides of rerailer 1 top bottom just are located and have seted up a set of spacing recess 7 respectively between rerailer 1 and the guide arch II 3, and the inside of spacing recess 7 is equipped with spacing ball 8.

In this technical scheme, the inside of spacing recess 7 is the narrow right width in a left side, the high curved surface type structure in a left side low in a right side.

The arrangement of the limiting groove 7 and the limiting ball 8 improves a stable and effective resistance to the steel rail on the rerailer, and prevents the locomotive from sliding due to insufficient traction force in the process of traction rerailing of the derailed locomotive.

The use method and the working principle of the embodiment are as follows:

firstly, the rerailer is clamped on a steel rail and a corresponding sleeper, then, a transmission sleeve 12 is rotated by a hexagonal wrench to enable a transmission screw I11 to move inwards so as to drive a movable pressing plate 10 on the rerailer to move inwards to extrude a bonding bag body I15, meanwhile, the bonding bag body I15 and the bonding bag body II 17 are mutually communicated and are deformed to be tightly bonded on the side surface of the steel rail under the extrusion action of the side surface of the steel rail until shear thickening liquid in the bonding bag body I15 and the bonding bag body II 17 is converted into a solid-like structure, and meanwhile, the transmission sleeve 12 is rotated to drive a transmission screw II 13 to move outwards so that the rerailer can be tightly bonded on the section of steel rail;

then, the derailed locomotive is driven to move forwards by using the traction mechanism, so that the steel wheel moves onto the rerailer, and the steel wheel is deflected under the extrusion guide effect of the guide protrusion I2 or the guide protrusion II 3 on the rerailer, when the rerailer moves to the position of the limiting ball 8 on the limiting groove 7, the limiting ball 8 on the rerailer is firstly extruded, so that the rerailer moves forwards along the track of the limiting groove 7 and retracts to one end of the limiting groove 7, and when the rerailer moves to the other end of the limiting groove 7, the limiting ball 8 moves downwards along the track of the limiting groove 7 and returns to the initial position under the influence of gravity, so that an effective supporting force is provided for the steel wheel on the rerailer, and the phenomenon of vehicle sliding is prevented;

when the locomotive moves to the top position of the rerailer, the protrusion of the edge of the steel wheel of the locomotive can sink into the guide groove I4 or the guide groove III 6, the rerailer is guided again so that the steel wheel can be accurately reset on the steel rail, meanwhile, the edge protrusion of the follow-up locomotive steel rail can directly pass through the rerailer through the guide of the guide groove II 5 on the rerailer without dismantling the rerailer, and the locomotive is dismantled after passing through the rerailer completely.
