Description

Technical Field

[0001] The present application relates to the field of rail transit technology, and in particular to a special track for a wheelset fault dynamic detection system. Background Art

[0002] Train wheels are important components of vehicles. Faults such as wheel flange overrun, abrasion, tread cracks and peeling will directly affect the safety and quality of vehicle operation, so real-time intelligent detection of wheels is necessary. The dynamic detection system for wheelset faults realizes dynamic detection of vehicle wheelsets and provides tooling guarantee for the safe operation of vehicles. When performing dynamic detection of wheelset faults, it is often necessary to drive the train onto a dedicated track and then use the dynamic detection system for wheelset faults to detect the train wheelsets.

[0003] However, the geometry, size and material selection of the wheelset detection track in the prior art are not rational, and the height value and other settings are unreasonable, so that the speed of the train passing through needs to be very slow, so the detection process is also slow and the detection efficiency is low.

[0031] The top surface of the running rail 2 matches the surface of the wheelset, the rail height at both ends is lower than the rail height in the middle, and the height transitions slowly;

[0032] Each guard rail 3 is arranged on the inner side of the connecting rail 1 and the running rail 2;

[0033] The detection device is arranged in the space between the guard rail 3 and the running rail 2 .

[0034] In the technical solution of the utility model, by reasonably designing the positional relationship between the connecting rail, the running rail and the guard rail, and reasonably designing the rail height of the connecting rail and the running rail, the running rail adopts a wheel-rail transition design, so that the wheel-rail profile matches the wheel profile, and a smooth wheel-rail transition is achieved, thereby reducing the wheel-rail impact as much as possible, and improving the running speed of the train on the dedicated track. At the same time, when the train passes, the detection equipment arranged between the guard rail and the running rail is used to detect the wheelset, which improves the detection efficiency and is also beneficial to the protection of the detection equipment.

[0035] In the technical solution of the present utility model, a variety of implementation methods can be used to implement the above-mentioned dedicated track for the dynamic detection system of wheelset faults. The following will take one of the implementation methods as an example to introduce the technical solution of the present utility model in detail.

[0036] For example, preferably, in a specific embodiment of the present invention, Figure 2 As shown, the connection assembly at the connection section 4 may include: a connection bolt 12, a spacer iron 13 and two washers 14;

[0037] At the side of the connecting rail 1 opposite to the running rail 2 at the connecting section 4, the rail bottom widths of the connecting rail 1 and the running rail 2 are reduced and closely opposite to each other;

[0038] The spacer iron 13 is arranged at the gap between the connecting rail 1 and the running rail 2, and is used to improve the tightness between the connecting rail 1 and the running rail 2, thereby improving the connection strength;

[0039] The two washers 14 are respectively arranged on the outside of the waist of the connecting rail 1 and the running rail 2, and the connecting bolt 12 passes through the through holes reserved in the washers 14, the running rail 2, the spacer iron 13 and the connecting rail 1, and is connected to the anti-loosening nut, thereby realizing a reliable connection between the connecting rail 1 and the running rail 2.

[0040] For another example, preferably, in a specific embodiment of the present utility model, Figure 3 As shown, the bottom width of the guard rail 3 is flush with the top width of the guard rail 3, thereby reserving installation space for the detection equipment.

[0041] In addition, preferably, as an example, the heights of both ends of the guard rail 3 may be lower than the middle height thereof.

[0042] In addition, preferably, in a specific embodiment of the present utility model, as Figure 3 As shown, a guard rail support 5 is provided on the side of the guard rail 3 away from the running rail 2, and is connected to the guard rail 3 by mounting bolts 6 and nuts 7, so as to ensure the stability of the guard rail installation.

[0043] Preferably, as an example, the mounting bolts 6 pass through the guardrail and the guardrail support from the inside to the outside, and the nuts 7 are located on the outside of the guardrail support, so that maintenance and inspection can be facilitated.

[0044] In addition, preferably, in a specific embodiment of the present invention, Figure 3 As shown, there is a preset distance L (for example, L may be 111 mm) between the tops of the running rail 2 and the guard rail 3 , so that a detection device 11 may be installed between the running rail and the guard rail, and a fault detection may be performed when a wheel passes through.

[0045] In addition, preferably, in a specific embodiment of the present utility model, as Figure 3 As shown, a pad structure 10 may be provided at the bottom of the guardrail 3 to raise the guardrail so that the top of the guardrail 3 is higher than the top of the running rail 2 (for example, the height h of the top of the guardrail 3 above the top of the running rail may be 22 mm) to protect the wheels from falling off when running on the running rail.

[0046] Preferably, as an example, an adjusting wedge 8 and a distance-adjusting cover plate 9 may be provided on the side of the running rail 2 away from the guard rail 3, so as to facilitate the construction, installation and on-site maintenance of the running rail.

[0047] Preferably, as an example, the connecting rail 1, the running rail 2 and the guard rail 3 are all made of alloy steel rails, so as to reduce wear and tear, reduce the maintenance workload, and improve the speed and safety of the train.

[0048] To sum up, in the technical scheme of the present invention, by reasonably designing the positional relationship between the connecting rail, the running rail and the guard rail, and reasonably designing the rail height of the connecting rail and the running rail, the running rail adopts a wheel-rail transition design, so that the wheel-rail profile matches the wheel profile, and a smooth wheel-rail transition is achieved, thereby reducing the wheel-rail impact as much as possible, and improving the running speed of the train on the dedicated track. At the same time, when the train passes, the detection equipment arranged between the guard rail and the running rail is used to detect the wheelset, which improves the detection efficiency and is also beneficial to the protection of the detection equipment.
