Abstract
Description
Technical Field
[0001] This utility model relates to the field of railway accessories technology, and in particular to a rail guard plate for railway tracks. Background Technology
[0002] Rail pads are pads placed between the frog guard rail and the turnout sleeper to provide a firm connection between the guard rail and the running rail (stock rail), ensuring the width of the guard rail wheel flange groove and the safety of train operation. The guard rail pads are one of the important components of the track, and their function is to ensure that vehicles can pass smoothly through the turnout frog section or special areas such as bridges without derailment accidents.
[0003] In existing technologies, guard rails need to be bolted to guard rail pads, which is very laborious and difficult to install. For example, Chinese utility model patent CN220450587U, entitled "A Railway Track Guard Rail Pad," requires bolts to be passed through an L-shaped plate, a support block, and the guard rail during installation. Then, nuts are installed on the inner end of the bolts, and finally, the nuts are tightened. Because this installation method involves inserting the bolts from the outside of the L-shaped plate towards the guard rail, it is difficult to pass them through in one go. It requires adjusting all three components back and forth to align the holes. The guard rail is heavy, making hole adjustment very laborious. Moreover, the close proximity of the rail and guard rail limits the space for tightening and loosening the nuts, making the operation difficult. Utility Model Content
[0004] The purpose of this utility model is to provide a rail guard plate for railway tracks, so as to solve the problem that the installation and disassembly of existing rail guards on the rail guard plate is very laborious and difficult.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A rail guard plate for railway tracks, wherein a main rail and a guard rail are mounted on the rail guard plate, and the rail guard plate is provided with a locking mechanism for fixing the guard rail; wherein... The locking mechanism includes a support block, a bracket plate, a bolt, and a nut. The bottom of the support block and the top of the bracket plate are provided with slots. The bracket plate is placed on the guard rail pad. The guard rail is placed on the guard rail pad. The bolt passes through the slots on the guard rail, the support block, and the bracket plate in sequence. The nut tightens the bolt. A positioning structure is provided between the slot on the support block and the bolt.
[0006] A further technical solution is: the positioning structure includes a strip-shaped protrusion disposed in the notch on the bracket plate and a strip-shaped groove disposed on the bolt and adapted to the strip-shaped protrusion.
[0007] A further technical solution is: a limiting sleeve with a notch is provided on the outer side of the bracket plate, and the inner cavity of the limiting sleeve is adapted to the nut.
[0008] A further technical solution is that the length of the nut is greater than the length of the limiting sleeve.
[0009] A further technical solution is that the outer end of the bolt is provided with an anti-loosening pin.
[0010] A further technical solution is that an L-shaped adjustment plate is provided between the guard rail pad and the guard rail.
[0011] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects: This utility model proposes a rail guard plate for railway tracks. This rail guard plate avoids the problem of bolts being difficult to insert, greatly facilitating the installation and fixing of the rail guard. Simply pre-install the bolts on the rail guard, and then, at the same time as installing the rail guard, place the bolts into the grooves on the bracket plate. Next, place the support block between the rail guard and the bracket plate, ensuring that the grooves on the support block also mate with the bolts. Finally, screw the nut onto the outer end of the bolt and lock the rail guard in place, reducing the workload and difficulty. Attached Figure Description

[0024] This implementation example Figure 1 , Figure 3 and Figure 5 As shown, a rail guard plate for railway tracks is provided. A main rail 2 and a guard rail 3 are installed on the rail guard plate 1. A locking mechanism 4 for fixing the guard rail 3 is provided on the rail guard plate 1. The locking mechanism 4 includes a support block 5, a bracket plate 6, a bolt 7 and a nut 8. The bottom of the support block 5 and the top of the bracket plate 6 are provided with slots 9. The bracket plate 6 is set on the rail guard plate 1. The guard rail 3 is placed on the rail guard plate 1. The bolt 7 passes through the slots 9 on the guard rail 3, the support block 5 and the bracket plate 6 in sequence. The nut 8 tightens the bolt 7. A positioning structure 10 is provided between the slot 9 on the support block 5 and the bolt 7.
[0025] The working process of this utility model is as follows: First, measure and calculate the distance between the main rail 2 and the guard rail 3. Then, fasten the guard rail pad 1 to the sleeper with bolts. Next, pre-install the bolt 7 on the guard rail 3. Then, at the same time as installing the guard rail 3 on the guard rail pad 1, ensure that the bolt 7 falls into the notch 9 on the bracket plate 6. Next, place the support block 5 between the guard rail 3 and the bracket plate 6, and ensure that the notch 9 on the support block 5 also matches the bolt 7. Finally, screw the nut 8 on the outer end of the bolt 5 and lock the guard rail 3. This reduces the labor intensity and difficulty, avoids the problem of bolts being difficult to insert, and greatly facilitates the installation and fixing of the guard rail.
[0026] It is worth noting that the notch 9 on the corbel support plate 6 and the notch 9 on the support block 5 face opposite directions. In addition, the support block 5 is restricted by the guard rail 3. Together, they achieve the effect of preventing the bolt 7 from coming off the notch 9. Example
[0027] Based on the above embodiments, this embodiment shows that the positioning structure 10 includes a strip-shaped protrusion 11 disposed in the groove 9 on the bracket plate 6 and a strip-shaped groove 12 disposed on the bolt 7 and adapted to the strip-shaped protrusion 11.
[0028] The strip-shaped protrusion 11 and strip-shaped groove 12 of the positioning structure 10 engage with each other to prevent the bolt 7 from rotating and to facilitate the screwing of the nut 8 into or out of the bolt 7. Example
[0029] Based on the above embodiments, this embodiment, for example Figure 2 and Figure 4 As shown, a limiting sleeve 13 with a notch is provided on the outer side of the bracket plate 6, and the inner cavity of the limiting sleeve 13 is adapted to the nut 8.
[0030] The limiting sleeve 13 is fixed on the bracket plate 6 to accommodate and fix the nut 8, thereby preventing the bolt 7 from moving up and down.
[0031] Preferably, the length of the nut 8 is greater than the length of the limiting sleeve 13.
[0032] Nut 8 protrudes from the limiting sleeve 13, making it easy to rotate nut 8.
[0033] Preferably, the outer end of the bolt 7 is provided with an anti-loosening pin 14.
[0034] Anti-slip pin 14 prevents nut 8 from slipping off bolt 7.
[0035] Preferably, an L-shaped adjusting plate 15 is provided between the guard rail pad 1 and the guard rail 3.
[0036] L-shaped adjusting plate 15 is used to adjust the height of guard rail 3.
[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
