Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a means for fastening rails in a turnout of a railway track.
[0002]
[Prior art]
The means for fastening the rail in the branching device implemented so far can be roughly classified into a bolt fastening method and a wire spring clip method.
Of these, the bolt fastening method, in any case, retightening due to loosening of the bolts, periodic fastening management is required, requiring maintenance work, and if the loosening of the bolts is left unattended, rail advance will occur and it will not convert We are jealous of the danger of accidents.
On the other hand, in the wire spring clip system, when the point floor plate or the general tie plate is elastically fastened, there is a risk of derailment due to damage to the clip and enlargement of the gauge when an excessive load occurs. In addition, the workability is poor because the clip must be completely removed when the rail of the installed branching device is replaced.
[0003]
[Problems to be solved by the invention]
The present invention has been made in view of the above circumstances, and while using a wire spring clip, a normal load is received by a spring, and when an excessive load is generated, it is received by a gate-type gate of a floor board, and the clip is damaged and has a gap. There is no danger of derailment due to expansion, and it is possible to set the rails in advance by setting them on the floor plate without removing the clips completely when replacing the rails of the installed branching devices. An elastic rail fastening device that can be attached and detached with a tool is provided.
[0004]
[Means for Solving the Problems]
To achieve the above object, the present invention provides a structure for receiving the transverse pressure in the splitter, the floor plate 1 supporting the rail R; those INCLUDED groove 2b on the inner side of both pillars 2a provided at both ends of the bridge 2c is formed A clip receiving gate 2 integrally provided on the floor plate 1 ; a stepped tooth type loose washer 4 having a step 4a formed on the rail R side on the upper surface; and the rail R on the lower surface. A rail brace 3 having a step 3b formed on the opposite side of the rail, and a tip 3a contacting the upper abdomen and base of the rail R; and a substantially W-shaped bend in which outer folded ends 5b are formed on both sides of the central mountain 5a Ru and a wire spring clip 5.
[0005]
Then, the tip of the rail brace 3 by inserting the rail brace 3 to the passage space of the gate-shaped gate 2 step portion 3b of the stepped portion 4a and rail brace 3 of the washer 4 in a state that has bitten if missing formula part 3a was in contact with the abdomen and the base portion on the rail R; said rail brace pushes the central peak portion 5a of the clip 5 from the gap between the bridge 2c of the upper surface 3c and the gate-shaped gate 2 of the rail brace 3 3, and the outer folded end 5 b of the clip 5 is applied to the contact groove 2 b of the gate-type gate 2 to elastically deform the clip 5 and contact the upper surface 3 c of the rail brace 3. It is a rail fastening device.
[0006]
Further, as a structure that does not receive the lateral pressure, a clip receiving gate type gate 2 is integrally provided on the floor plate 1 and provided with an outer folded end abutting groove 2b of a wire spring clip inside both gate pillars 2a.
[0007]
Then, the central mountain portion 5a of the substantially W-shaped bent wire spring clip 5 is pushed through the gap of the bridge 2c of the gate-type gate 2 to suppress the flange portion of the rail R, and the outer folded end 5b of the clip 5 is pushed into the contact groove 2b. It is an elastic rail fastening device constituted by being applied to the.
[0008]
Note that the clip receiving gate 2 can be used by being embedded in a wooden sleeper, a synthetic sleeper, or a concrete sleeper or integrated with an iron sleeper.
[0009]
[Operation and effect of the invention]
The present invention is as described above. In the embodiment using the rail brace 3 of FIG. 1 (structure receiving the lateral pressure), the embodiment of pressing the base of the rail R directly in FIG. In addition to being able to fasten one-touch with the force of the spring, the impact force can be mitigated by elasticity, the life of the parts can be extended, and the common effect of using the wire spring clip to realize the simplification of the structure can be obtained The following special effects that cannot be expected from the conventional wire spring clip system are brought about.
[0010]
(B) The normal load is received by a spring, and if an excessive load is generated, it is received by the clip receiving gate 2 on the floor board, and the risk of derailment due to damage to the clip and expansion of the gauge is eliminated.
(B) It is excellent in workability because it is set in advance on the floor plate and is shifted when the rail is installed without completely removing the clip when replacing the rail of the installed branching device.
(C) Since the outer folded end of the substantially W-shaped bent wire spring clip 5 is sandwiched between the contact grooves 2b and 2b on the inner sides of the two gate pillars 2a of the gate-shaped gate 2, the spring stress is always maintained stably and reliably. Is done.
[0011]
(D) The clip can be attached / detached with a single instrument (insulator) provided with inner and outer hooking members at both side bent valleys of the clip 5.
(E) Because of the above advantages, it is possible to significantly reduce the maintenance and management of turnouts.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
1 to 3 show a structure for receiving a lateral pressure. That is, on the floor board 1, the clip receiving gate type gate 2 provided with the outer folded end abutting groove 2b of the wire spring clip inside the both gate pillars 2a is integrally provided.
[0013]
Then, a rail brace 3 in which the lower corner of the rear end shown in FIG. 3 is engaged with the stepped tooth type loosening washer 4 in a notched manner is inserted into the passage space of the gate-shaped gate 2, and the front end portion 3 a is inserted. It abuts on the upper abdomen and flange of the rail R.
[0014]
Then, the central mountain portion 5a of the substantially W-shaped bent wire spring clip 5 is pushed in through the gap between the upper surface of the rail brace 3 and the bridge 2c of the gate-type gate 2 to restrain the end portion 3a of the rail brace 3 and to turn the clip 5 outward. The end 5b is applied to the contact groove 2b to constitute an elastic rail fastening device.
[0015]
4 to 6 show a structure that is not subjected to lateral pressure. That is, on the floor board 1, the clip receiving gate type gate 2 provided with the outer folded end abutting groove 2b of the wire spring clip S inside the both gate pillars 2a is integrally provided.
[0016]
Then, the central mountain portion 5a of the substantially W-shaped bending wire spring clip 5 is pushed through the gap of the bridge 2c of the gate-type gate 2 to directly restrain the flange portion of the rail R and the outer folded end 5b of the clip 5 is brought into contact. The elastic rail fastening device is configured by being applied to the groove 2b.
[0017]
FIG. 7 shows a clip attachment / detachment lever 6 provided with an internal / external hooking member 6a in a bent valley portion on both sides of the clip 5 in an embodiment in which the lateral pressure is not received.
