Description

Technical Field

[0001] The utility model belongs to the technical field of rails, and in particular relates to a steel rail connecting line installation structure. Background Art

[0002] At present, the ends of two adjacent butted rails on the track need to be equipped with connecting wires for electrical connection to ensure electrical conduction between the two adjacent rails to transmit weak current signals. If the connecting wire between the two adjacent rails is electrically disconnected, the terminal equipment is likely to experience a "red light band" phenomenon. In the prior art, both ends of the connecting wire are directly connected to the waist of the two rails, and the connection method between the connecting wire and the waist of the rail belongs to the prior art, such as the content recorded in the railway industry standard TB-1458-83 "JS type nail-type rail connecting wire". At present, both ends of the connecting wire are fixed to the rails, but the middle part is suspended, and the train on the track will vibrate when passing by. At this time, the middle part of the connecting wire will vibrate accordingly, and may even collapse or arch upward to the top of the rail. Over time, due to rust of the connecting wire or crushing of the rail wheel, the connecting wire may become loose or broken, which leads to a short circuit in the track circuit. In the prior art, the installation structure of the two rail ends is such as Figure 1-Figure 4 As shown, one side or both sides of the two rails are connected by a connecting strip at the waist, and the middle part of the connecting line is suspended without any support limit.

The limiting piece 5 is arranged in the middle part corresponding to the length direction of the connecting line 1, and the limiting piece 5 is connected to any one of the connecting pieces 4. The limiting piece 5 is used to limit the middle part corresponding to the length direction of the connecting line 1. By adding a limiting piece connected to the connecting piece in the middle part of the connecting line, the limiting piece can limit the connecting line, especially avoiding the jumping of the connecting line due to the vibration of the rail, and its aesthetics is good.

[0036] like Figure 6As shown, in the above technical solution, two connecting bars 2 are provided, and the two connecting bars 2 are respectively provided on both sides of one end of the two rails 3 close to each other, and the multiple second connecting holes 21 on the two connecting bars 2 correspond to each other and are aligned with each other, and each first connecting hole 31 and the two second connecting holes 21 aligned therewith are inserted into one connecting piece 4 together, so as to fasten the two connecting bars 2 to both sides of one end of the two rails 3 close to each other, so that the connection stability of the ends of the two adjacent rails close to each other is better, thereby reducing the amplitude of the vibration of the rail ends.

[0037] At this time, after the ends of the two rails close to each other are aligned, the ends close to each other are clamped by two connecting strips and assembled by multiple connecting pieces, and the installation effect is good at this time.

[0038] like Figure 8 and Fig. 9 As shown, in the above technical solution, a plurality of connecting wires 1 are provided, the lengths of the plurality of connecting wires 1 are different from each other, and the middle parts of the plurality of connecting wires 1 are twisted together and limited by the limiting member 5, so that the plurality of connecting wires are redundantly designed, thereby improving the reliability of the track circuit.

[0039] In the above technical solution, the connecting wires 1 are provided with 2-4 (can be 2, 3 or 4) pieces, which has a simple structure and is easy to install. Specifically, two connecting wires are preferred.

[0040] like Figure 5 and Figure 8 As shown, in the above technical solution, a plurality of limiting members 5 are provided, and the plurality of limiting members 5 are spaced apart in the middle part of the connecting wire 1 along its length direction, and each of the limiting members 5 is connected to the connecting member 4 close thereto, so that the middle part of the connecting wire is limited by a plurality of limiting members, thereby making the limiting effect of the connecting wire better.

[0041] In the above technical solution, 2-4 (may be 2, 3 or 4) limiting members 5 are provided, which has a simple structure and has a good limiting effect on the connecting wire. Specifically, two limiting members are preferably provided.

[0042] like Figure 5 and Figure 8 As shown, in the above technical solution, each end of the two rails 3 close to each other has at least one limiting member 5, so that the limiting effect of the connecting line is better.

At this time, the limiter can be installed on the corresponding connecting member, specifically, the connecting bolt passes through the two second connecting holes, and then the connecting nut is tightened to clamp the limiter between the connecting nut and the connecting strip, and then the groove bottom of the upper end of the limiter is bent to be supported on the upper end of the connecting strip). Since the limiter is rigid, it has good support for the middle part of the connecting wire.

[0045] The limiting member 5 in the above technical solution is a galvanized iron sheet member, which has a simple structure and good durability.
