JP4889440B2 - Rail accessory mounting device for railroad turnout - Google Patents

Description

  The present invention relates to a means for attaching a rail accessory in a railway turnout.

  Conventionally, metal fittings for railroad turnouts (metal fittings that are attached to the abdomen of the tongrel, movable rail, basic rail, or square rail so that the tongrel or movable rail will not bend due to wheel lateral pressure. From the JIS railway terminology dictionary) Axial force transmission device (branch switch) for long rods (rails welded to a length of 20 m or more), long rods (rails welded to a length of 20 m or more), rods that connect two tongrels to reduce lateral deflection of the tongrels In many cases, bolts and nuts are fastened to the abdomen of various rails, which are attached to prevent the relative movement of the basic rail and the lead rail from moving back and forth in the vicinity of the joining long rail.

  If the mounting bolts and nuts fall off due to loosening or breakage, the parts may loosen or fall off and fail to perform their functions, which may cause a failure in the function of the railway branching device. .

  The acting force due to the load when the vehicle passes through the railroad branching device acts on each of the above parts through the bolts and nuts for mounting described above, and concentrated stress is generated around the hole drilled in the rail by the action. Will occur. If this stress causes cracks around the rail holes, the cracks will develop as the vehicle passes through, leading to damage to the rails and causing a derailment accident. .

Moreover, even if it is going to attach the said part of a railroad branching device using the adhesive material which impregnated the thermosetting resin to the rail for a railroad branching device, it has to be heat-bonded with a gas burner in a factory, and high pressure gas An operator who requires specialized skills is required for handling, and cannot be easily performed. Moreover, the heat-curing work by the gas burner performed in the factory is not suitable for the heat-curing and bonding work in the field because dedicated equipment is required.
None.

  First, according to the present invention, a bolt / nut attached to a rail of a railroad branching device is broken and loosened to cause a drop, and at least one of the stopper plate, the retaining rod, and the connecting plate of the long rail axial force transmission device. The problem is to prevent the failure of one function.

  Secondly, in the present invention, when a crack is generated from the periphery of the hole drilled in the rail of the railroad branching device, the crack progresses to break the rail, and the rail is divided and separated from the damaged portion. Prevention is an issue.

  Thirdly, the present invention relates to a railroad branching device using an adhesive material impregnated with a thermosetting resin for a railroad branching fastener, a retaining rod coupling plate and a long rail axial force transmission device coupling plate. In order to adhere to the rail, it is an object of the present invention to easily heat and bond in the field without using a gas burner in a factory and without using an expert.

According to the present invention, a second adhesive is provided in which an attachment plate is attached to one side of the abdomen of the rail via a first adhesive material impregnated with a thermosetting resin, and the other side of the abdomen of the rail is impregnated with a thermosetting resin. At least one part of a stopper, a connecting plate of a retaining rod and a connecting plate of a long rail axial force transmission device is attached via a material, and the first and second adhesive materials impregnated with the thermosetting resin are heated. Adhering at least one part of the attachment plate, the stopper, a connecting plate of the retraction bar, and a connection plate of the long rail axial force transmission device to both sides of the abdomen, and the attachment plate, the first and second adhesives Holes, holes in the rail abdomen, and bolts that pass through the holes are fastened with nuts, and the attachment plate. To heat the first and second adhesives It is characterized in that the electric heater insertion hole drilled in the rail direction.

According to the present invention, the acting force from the rail of the railroad branching device is applied to at least one part of the stopper of the railroad branching device, the connecting plate of the retaining rod, and the coupling plate of the long rail axial force transmission device. Since the adhesive material impregnated with thermosetting resin between the part and the rail is dispersed and acted on the rail by the heat-bonded adhesive layer, the acting force acting on the mounting bolts and nuts is relaxed, and the bolts and This has the effect of preventing the nut from loosening or breaking.

  In addition, even if cracks develop from the periphery of the hole drilled in the rail of the railroad branching device and the rail is divided, the attachment plates on the parts and the rail abdomen are impregnated with thermosetting resin. Since the adhesive is bonded to the rail by the adhesive layer obtained by heat-bonding the adhesive, the rail can be prevented from being dispersed.

Further , according to the present invention, at least one part of a stop plate of a railroad branching device, a connecting plate of a stay rod and a connecting plate of a long rail axial force transmission device is used for a railroad by using an adhesive material impregnated with a thermosetting resin. When adhering to the rails of the branching device, drilling in the rail direction on the attachment plate, inserting an electric heater into this hole and heating the thermosetting adhesive makes the heat curing work easier, Installation by an expert is not required, and it can be installed easily, quickly and inexpensively.
