[0002] The turnout top iron is an important connecting part of the turnout equipment. Because the turnout point rail and heart rail need to be frequently switched, but fasteners cannot be installed on both sides, a transverse top iron is required to resist the outward flipping of the point rail and heart rail caused by the lateral force of the train. Although the structure is simple, a well-installed and standard-sized top iron plays an important role in the smooth operation of trains and reducing turnout switching failures.
[0003] A certain gap should be maintained between the top iron end and the point rail or heart rail. However, this gap standard is very difficult to maintain on site, which may lead to adverse conditions in railway turnout conversion in the long run.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0019] Reference Figure 1-Figure 3, an improved top iron structure for railway turnout, comprising track 1 and track 2, track 2 is located on the right side of track 1, the outer wall of track 1 is fixedly connected with top iron 2 9, the outer wall of track 2 is fixedly connected with top iron 1 5, the outer wall of top iron 2 9 is fixedly connected with multiple tooth blocks 2 6, the outer wall of top iron 5 is fixedly connected with multiple tooth blocks 3, top iron 5 is provided with two openings, top iron 2 9 is provided with two threaded holes, top iron 2 9 is respectively connected with the two threaded holes by two bolts 4, the two bolts 4 extend to the openings and are threadedly connected with track 2, multiple tooth blocks 2 6 are evenly arranged on the outer wall of top iron 2 9, multiple tooth blocks 3 are evenly arranged on the outer wall of top iron 5, the length of top iron 5 is greater than the length of top iron 2 9, multiple tooth blocks 3 are in contact with the outer wall of top iron 2 9, multiple Tooth block 2 6 is in contact with the outer wall of top iron 1 5. Compared with general top irons, top iron 1 5 is installed on track 2 2 by bolt 4. The basic principle is to ensure that the strength of the rail is not reduced, so the original rail threaded hole cannot be enlarged or the threaded hole cannot be increased. The end of bolt 4 is designed to form an anti-loosening structure with top iron 1 5 and top iron 2 9 to keep the fitting surface of top iron 1 5 and top iron 2 9 with the basic rail unchanged and prevent stress concentration caused by uneven fitting surface. The more complex the structure, the more likely it is to have unexpected situations. Therefore, the complexity of top iron 1 5 and top iron 2 9 is minimized. Without changing the force process and reducing the firmness, stability and safety of the connecting parts, small changes are made to top iron 1 5 and top iron 2 9 to adapt them to on-site needs and seasonal needs, reduce on-site workload, and reduce the stress level of the rail parts.
[0020] The outer wall of the track 1 is adsorbed with a plurality of magnets 11, and the outer walls of the plurality of magnets 11 are fixedly connected with a fixed cylinder 10. A fixed plate 8 is provided on the outer side of the track 1, and a plurality of telescopic rods 7 are fixedly connected to the outer wall of the fixed plate 8. The plurality of telescopic rods 7 are respectively slidably connected with the inner wall of the fixed cylinder 10. A sliding groove 14 is provided on the outer wall of the fixed plate 8, and a rotating rod 13 is fixedly connected to the outer wall of the fixed plate 8. An oil pipe 12 is rotatably sleeved on the outer wall of the rotating rod 13, and the end of the oil pipe 12 is slidably connected with the inner wall of the sliding groove 14. The plurality of magnets 11 are uniformly adsorbed on the outer wall of the track 1, and the plurality of telescopic rods 7 are uniformly arranged at the four corners of the fixed plate 8. The length of the oil pipe 12 is the same as that of the fixed plate 8. The lengths of the fixed plates 8 are equal. After the top iron 5 and the top iron 2 9 have been used for a period of time, the personnel can use the fixed plate 8 to make the multiple magnets 11 adsorb on the track 1 or the track 2 2, and then adjust the position of the fixed plate 8 by pulling the telescopic rod 7, and then move the end of the oil pipe 12 upward along the sliding groove 14, and then inject lubricating oil through the oil pipe 12. The lubricating oil flows to the top iron 5 or the top iron 2 9 by gravity, so as to facilitate the lubrication operation of the top iron 5 and the top iron 2 9, so as to maintain a good lubrication state between the top iron and the wheel, reduce wear and energy consumption, and thus quickly and conveniently perform lubrication operations on places where it is difficult to apply lubricating oil, thereby improving practicality.
[0021] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
