SU31298A1 - Rail Attachment to Sleepers - Google Patents

Description

h

The invention relates to devices for attaching rails to sleepers by means of linings provided with ribs and clamping pads attracted to bolts of HUMfi fasteners with bolts. In the proposed adaptation ribs. the liners are provided with transverse cuts to install the heads of the fastening bolts in them, and to adjust the track width, strips are used, inserted between the rail bottom and the ribs of the liner.

In FIG. 1 and 2 depict the device in a vertical section and in the plan; FIG. 3-section of the fixture using iron sleepers; FIG. 4 is a section along the line LP in FIG. 2; FIG. 5, 6 and 7 is a longitudinal section of the plan and side view of the lining; FIG. 8 and 9 - two types of fastening bolt; FIG. 10 and 11 are two types of clamping plates; FIG. 12, 13 and 14 are three kinds of slats for adjusting the gauge; FIG. 15, 16 and 17 are three kinds of modified bar for adjusting the track width.

In the proposed device (Figs. 1 and 2), the lining a, having openings only for d screws, attaching it to the sleeper, is provided with ribs b with popp-325

river, tapering upward notches 5 (Figs. 5, 6 and 7), into which Z of the fastening bolts / (Figs. 4, 8 and 9) can be inserted into the side. The track rails z are laid on the lining and between its ribs b and pressed against the latter with clamping plates A (Figs. 10 and 11), bolted to the lining with bolts /, and the edges of the linings A which are in contact with the rail and lining can be attached to For better fit, different slopes, and for adjusting the track gauge, they can be equipped with tides (Fig. 3 and 10) of various sizes.

In order to adjust the track width, narrow strips T (Figs. 1, 12, 13, and 14) inserted between the rail and rib L can also be used, which, in order to prevent them from sliding upwards, canted face X and provided with protrusions n abutting in order to avoid lateral movement of the slats in the faces of the clamping plates. The strips for adjusting the track width can be modified (Figs. 15-17) and provided with protrusions v entering the notches S of the ribs L of the lining, thereby eliminating the possibility of lateral shear.

When iron sleepers are used, the lining is fixed on the tie by welding (Fig. 3); the lining may also be completely absent, in which case the ribs are made on the sleeper itself.

The subject of the patent.

L. A device for attaching rails to sleepers, in which a track rail laid between lining ribs is pressed against the latter by means of clamping pads and fixing bolts, characterized in that

the ribs b (Figs. 1, 2, 5, 6) on the upper side of the lining are provided with transverse cuts s of a tapering up shape for lateral insertion and installation of the heads of fastening bolts.

2. The use of the fixture inserted between Clause 1 and the ribs of the lining of the narrow slats m (Fig. 1), which are used for adjusting the track width, with protrusions n (Fig. 12-14) resting on the faces of the clamping plates L, the projections v (Figs. 15-17, included in the notch S of the lining ribs, to prevent lateral movement of the slats
