Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of railway transportation equipment, and particularly relates to a switch rail fixing device. Background Art
[0002] A switch is a line connection device that enables locomotives and rolling stocks to transfer from one track to another. A switch consists of a switch rail, a connecting part, a frog, and guard rails. The switch rail is an important component in the switch rail of a switch and is also a weak link in the switch equipment. To a certain extent, the state of the switch rail determines the quality of the switch. At the switch where the train passing frequency is high, the problem of the switch rail exceeding the limit will occur every once in a while. And the exceeding of the limit will cause the switch rail not to be in close contact with the running rail. The non-close contact between the switch rail and the running rail will lead to the "frog squeezing" accident, and in severe cases, it may cause serious traffic accidents such as derailment and running off the track when the train passes through the switch. Summary of the Invention
[0003] Aiming at the defects of the prior art, the utility model provides a switch rail fixing device. When the switch rail of the switch is not in close contact with the running rail due to exceeding the limit, the device of the utility model is installed at the bottom of the switch rail and the running rail to ensure that the switch rail is in close contact with the running rail and eliminate potential accident hazards.
[0004] A switch rail fixing device, the structure of which includes: a T-shaped fixing base 1, a switch rail pressing block 2, a running rail pressing block 3, an inner wedge block 4, a fixing block 5, a bolt 6, and a locking nut 7. The fixing block 5 is welded to one end of the T-shaped fixing base 1. The other end of the T-shaped fixing base 1 sequentially passes through the running rail pressing block 3 and the switch rail pressing block 2. The inner wedge block 4 is inserted into the T-shaped fixing base 1 to adjust the position of the switch rail pressing block 2 on the T-shaped fixing base 1 to make it fit with the inner wedge block 4. The bolt 6 is sequentially screwed into the fixing block 5 and the locking nut 7 and abuts against the running rail pressing block 3.
[0005] The switch rail pressing block 2 and the running rail pressing block 3 of the switch rail fixing device are respectively processed with T-shaped grooves to cooperate with the T-shaped fixing base 1.
[0006] The switch rail pressing block 2 of the switch rail fixing device is processed with a semi-circular arc groove to cooperate with the outer arc surface of the inner wedge block 4. With this arc surface cooperation relationship, the switch rail pressing block 2 can still maintain good contact and cooperation with the inner wedge block 4 when generating an angular displacement during operation.
[0007] The beneficial effects of the present utility model are as follows: When the switch point rail is not in close contact with the running rail due to over-limit at the switch point rail part, the device of the present utility model is installed at the bottom of the switch point rail and the running rail. By rotating the bolt, the switch point rail pressing block and the running rail pressing block gradually approach each other, thereby driving the switch point rail and the running rail to gradually approach each other. When the switch point rail and the running rail are in close contact, the locking nut is rotated to lock and fix. The present utility model eliminates the potential accident hazard of "fork squeezing" caused by the non-close contact between the switch point rail and the running rail, and ensures the driving safety of the locomotive.

[0014] The following further describes the present utility model in conjunction with the drawings and specific embodiments.
[0015] Referring to Figures 1-5 , the present utility model provides a technical solution: A switch point rail fixing device, whose structure includes: a T-shaped fixing base 1, a switch point rail pressing block 2, a running rail pressing block 3, an inner wedge block 4, a fixing block 5, a bolt 6 and a locking nut 7. The fixing block 5 is welded to one end of the T-shaped fixing base 1. The switch point rail pressing block 2 and the running rail pressing block 3 are respectively processed with T-shaped grooves and cooperate with the T-shaped fixing base 1. The other end of the T-shaped fixing base 1 passes through the running rail pressing block 3 and the switch point rail pressing block 2 in sequence through the T-shaped groove. The inner wedge block 4 is inserted on the T-shaped fixing base 1. The switch point rail pressing block 2 is processed with a semi-circular arc groove to cooperate with the outer arc surface of the inner wedge block 4, and the position of the switch point rail pressing block 2 on the T-shaped fixing base 1 is adjusted to make it cooperate with the outer arc surface of the inner wedge block 4. By adopting this arc surface cooperation relationship, the switch point rail pressing block 2 can still maintain good contact and cooperation with the inner wedge block 4 when generating an angular displacement during operation. The fixing block 5 is processed with a threaded hole, and the bolt 6 is screwed into the fixing block 5 and the locking nut 7 through the threaded hole and abuts against the running rail pressing block 3.
[0016] By rotating the bolt 6, the switch rail pressing block 2 and the running rail pressing block 3 are gradually brought closer, thereby driving the switch rail and the running rail to gradually approach. When the switch rail and the running rail are closely attached, the locking nut 7 is rotated to lock and fix. The utility model eliminates the potential accident hazard of "fork squeezing" caused by the non-close contact between the switch rail and the running rail, and ensures the driving safety of the locomotive.

Specific examples are used in this article to elaborate on the principle and implementation manner of the utility model. The description of the above implementation cases is only used to help understand the method and its core idea of the utility model. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the utility model, several improvements and modifications can still be made to the utility model, and these improvements and modifications also fall within the protection scope of the claims of the utility model.
