Abstract
Description
Technical Field
[0001] This utility model relates to the field of rail wear measurement technology, specifically to a flange simulation measurement device for the wear amount of the base rail. Background Technology
[0002] In railway transportation, trains run on two rails. During operation, they are inevitably affected by other trains and stations where passengers board and alight. Train rerouting is a necessary consequence. Switches on the track are the railway equipment that enables train rerouting. A switch consists of a switch rail, stock rail, etc., with the switch rail being the first component to initiate the rerouting. Switch rails wear down due to the impact of train wheels. Once the wear exceeds a certain threshold, the switch rail must be replaced; otherwise, train safety will be compromised, and derailment accidents are highly likely, causing significant personal injury and property damage to passengers. To ensure the safe passage of trains through switches, the switch rails must be kept in good condition. Currently, the assessment of switch rail condition relies on the experience of staff at various levels, which poses a significant safety hazard. Utility Model Content

[0029] Example 1
[0030] Appendix Figures 1-2 The wheel flange simulation measuring device for the wear amount of the base rail according to this utility model includes: a measuring frame 10 and a plug gauge 7;
[0031] The measuring frame 10 is equipped with a handle 9 at one end;
[0032] A fixing mechanism 2 is connected to the outer side of the other end of the measuring frame 10, and a simulated wheel rim 1 is provided on the top of the fixing mechanism 2;
[0033] The bottom of the fixed mechanism 2 is equipped with a rotatable turntable 3, and the bottom of the simulated wheel rim 1 is connected to the top of the turntable 3;
[0034] The bottom of the turntable 3 is equipped with a first measuring tool 5 and a second measuring tool 4.
[0035] According to the embodiments of this utility model, both the first measuring tool 5 and the second measuring tool 4 are arc-shaped structures.
[0036] According to an embodiment of the present invention, the inner diameter of the first measuring tool 5 is smaller than the inner diameter of the second measuring tool 4.
[0037] According to an embodiment of this utility model, the diameter of the plug gauge 7 is 4mm.
[0038] According to an embodiment of the present invention, a level 11 is provided on the top of the measuring frame 10.
[0039] According to an embodiment of the present invention, the measuring frame 10 is mounted on the basic rail 8, and a tip rail 6 is provided on one side of the basic rail.
[0040] According to an embodiment of the present invention, the simulated rim 1 can rotate, and the simulated rim 1 drives the turntable 3 to rotate during the rotation process.
[0041] Measurement Principle: The flange simulation measurement is designed for inspecting the wear of the base switch rail 6. It is specifically used for inspecting special structures such as turnouts and rail expansion joints. The first gauge 5 simulates a wheel tread worn to its limit with an angle, and together with the φ4mm clearance gauge, it is mainly used to detect the structural condition of the base switch rail 6. The second gauge 4 simulates a new wheel tread and is mainly used to detect the wear condition of the switch rail 6.
[0042] When inspecting the structure of the base switch rail 6 using the first measuring tool 5 and the φ4mm clearance gauge, place the first measuring tool 5 flat on the base rail 8, perpendicular to the rail axis, so that the beveled vertex of the first measuring tool 5 is in close contact with the base rail 8. To ensure the accuracy of the inspection results, it is essential to ensure that the switch rail 6 and the base rail 8 are in close contact.
[0043] If the φ4mm gap gauge can be inserted between the tip of the switch rail 6 and the first measuring tool 5, and the upper edge of the tip of the switch rail 6 is higher than the lower edge of the first measuring tool 5, it is considered to be in compliance with the standard. If the φ4mm gap gauge cannot be inserted between the tip of the switch rail 6 and the first measuring tool 5, the tip of the switch rail 6 should be ground to the standard state or the base rail 8 on that side should be replaced.
[0044] When wear or chipping occurs on the tip of the switch rail 6, which is in close contact with the base rail 8, resulting in an uneven surface, the second measuring tool 4 should be used for inspection and evaluation. Place the second measuring tool 4 flat on the base rail 8, perpendicular to the rail axis, where it is in close contact with the switch rail 6.
[0045] If the bottom of the uneven surface of the switch rail 6 head caused by wear or chipping is higher than the lower edge of the second gauge 4, it is considered to be in a qualified state. In this case, the switch rail 6 head needs to be ground to round the corners to eliminate the uneven surface.
[0046] If the bottom of the uneven surface of the switch rail 6 caused by wear or chipping is lower than the lower edge of the second measuring tool 4, the length of the uneven surface needs to be measured. If the length of the uneven surface of the switch rail 6 does not exceed 200mm, it is still considered acceptable, and the switch rail 6 head needs to be ground to round off the uneven surface. If the length of the uneven surface of the switch rail 6 exceeds 200mm, it is still considered out of range, and the base switch rail 6 on that side needs to be replaced.
[0047] In summary, the flange simulation measurement device for the wear amount of the base rail 6 of this application can realize two different measurement modes by setting a first measuring tool 5 and a second measuring tool 4 of different sizes, and can quickly detect whether the wear of the base rail 6 exceeds the limit by using a plug gauge 7 in conjunction with the detection, thereby improving the safety of the base rail 6 in use.
[0048] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
