JP6799286B2 - Connecting device between tongue rail and rolling rod in railway turnout - Google Patents

Description

The present invention relates to a device for connecting a turnout rod to a tongue rail in a railroad turnout.

Conventionally, as shown in FIG. 9 , one end of each of the connection plates a1 and a2 is bolted and nut-tightened to each of the tongue rails R1 and R2, and the other ends of each of the connection plates a1 and a2 are fixed to the rod c. Fit into the side view U-shaped metal fittings e1 and e2, tighten the bolts b1 and nuts b2, connect the tongue rails R1 and R2 with the rolling rods c and c, and roll as shown by the arrows. The tongue rails R1 and R2 are converted by the left-right movement of the rod c and are separated from the basic rails r1 and r2.

None.

None.

The turning force acting on the tongue rail from the rolling rod when the tongue rail is converted (left and right movement of the rolling rod, pressing of the tongue rail against the basic rail) and the vibration of the tongue rail when the vehicle passes are U-shaped metal fittings. Since it acts on the bolts b1 and the nuts b2 that connect the rail and the connection plate, the nuts b2 may loosen and fall off, and the tongue rail and the rolling rod may separate, causing a derailment accident. It is considered to be.

Hand stage of the present invention, the projecting member and the front Kitotsu rail connect the tongue rail and the rolling iron rod and a concave member having an outer fitting portion pulled out incapable uneven fit corresponding to member in connection equipment of the tongue rail and the rolling iron rods in splitter, said recessed member has a hemispherical hole as the outer fitting portion with the inside made of corner pieces, moreover communicating with the hemispherical hole An opening is formed, and the opening locks the convex member on a first opening for inserting and removing a spherical band-shaped convex member on the side surface of the square piece, and on the facing surface of the convex member in the square piece. It is characterized in that the convex member is fixed to the tongue rail via a connecting plate, and the concave member is projected from the end of the turnout rod. To do .

According to the present invention, the rolling converted force acting from iron rods tongue rail and Ino tongue rail and the point lock rod Do is the outside possibility by the vibration of the vehicle passage when the tongue rail, of course, especially disconnect de impossible uneven, it is possible to extremely easily and securely be fitted, yet the assembled elevational work can be very easy and quick.

The whole side view which omitted the middle of the conventional example.

Conventionally and in the example of the present invention, the rolling rod 2 is not a single rod in the longitudinal direction thereof, but a pair of rolling rod portions 2a and 2b are insulated from each other at the center thereof as shown in FIG. A large number of parts such as bolts and nuts are connected to each other via a signal component for the purpose to form a single unit. However, since the above configuration is completely irrelevant in the present invention, its description and illustration are omitted.

Further, in the present specification and claims, the expression "spherical band shape" is used, but as seen in FIGS. 1, 2, 4 and 5, a sphere extends from the intervening piece 32 to the outward edge of the convex member 3. In the case of a band, it means that the outer edge of the convex member 3 as seen in FIGS. 7 and 8 is cut vertically, and most of the convex member 3 includes a ball band, strictly speaking, a part of the ball band. The corresponding portion is a hemispherical hole 4a.

In the present invention, as shown in FIGS. 1 and 4, bolt insertion holes 35 and 35 are bored on the left and right sides of a substantially rectangular parallelepiped connecting plate 31 having a shape in which the outward surface 33 abuts on the inward surface of the tongue rail 1, and the connecting plate 31 is formed. An inwardly facing intercalated piece 32 is projected from the center of the intercalated disc 32, a convex member 3 formed in a spherical band shape is projected inwardly from the intercalated disc 32, and a connecting plate 31 is provided through bolt insertion holes 35 and 35. Tighten the bolts and nuts to 1.

On the other hand, recessed members 4 and 4 composed of square pieces 42 and having an opening 41 are welded to both ends of the rolling rod 2. The elongated piece of reference numeral 21 bolted to both ends of the rolling rod 2 is a jump-up prevention portion of the tongue rail 1, but the description thereof will be omitted because it is irrelevant to the present invention.

As shown in FIG. 5, each concave member 4 has an opening 41 formed in the square piece 42, and the entire convex member 3 in the upright state is extrapolated when the side surface thereof is in the lower surface state, and the convex member 3 is extrapolated in the side surface state. A first opening 41a for retaining the member and a second opening 41b in which the convex member 3 in an upright state is locked to the concavo-convex facing surface of the square piece 42 and cannot be removed are continuously provided. As shown, a hemispherical hole 4a is bored inside the square piece 42, and as a result, the contact portion of the hemispherical hole 4a with the surface portion of the convex member 3 becomes the extrapolated portion 40.

Next, to explain the assembly method of the present invention, the connecting plate 31 is fixed to the tongue rail by bolting and nuts, and as shown in FIG. 5 (1), the rolling rod 2 is erected at a right angle. The first opening 41a having an arc 41c (shown in FIG. 5 (3)) at the inner end is directed downward, and each concave member 4 is lowered in the direction of the arrow (a) and stands upright as shown in FIG. 5 (2). It is extrapolated to the entire convex member 3 in the state, and then rotated in the arrow (b) direction of FIG. 5 (2), that is, in the perpendicular direction, and the convex member 3 is formed by the hemispherical hole 4a as shown in FIG. 5 (3). It is fitted externally and locked at the second opening 41b so that the convex member 3 cannot be removed. Further, as shown in FIG. 3, the convex member 3 is in a retaining state at the first opening 41a. Since the inside of the recess member 4 is a hemispherical hole 4a as shown in FIG. 6, the rotation is smoothly performed.

The one shown in FIG. 7.8 is a modified example of the present invention, in which the outward edge, that is, the tip of the convex member 3 is cut vertically as described above, and the other structures are the same as those in the above-mentioned example and are the same. The detailed description thereof will be omitted with reference to the reference numerals.

The above-mentioned example has a higher fitting property, and the modified example has a lower material cost and is sufficient.
