Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As shown in Figure 1 and Figure 2, a kind of measurement mechanism that is used to measure rail wear is made up of chi frame 1, survey chi 2, and chi frame 1 is whole sheet; Its base, chi frame 1 upper edge make progress recessed one the location groove 4; Bottom, left side on the positioning groove 4 is provided with and rail head of rail 8 reference field 5 that matches, and the left upper portion on the positioning groove 4 is provided with a rectangular indentation 6.This breach 6 can be dodged the fat edges of non-acting surface, and reference field 5 is not subjected to the influence of rail head of rail 8 abrasion and distortion, guarantees that reference field 5 and the non-acting surface in rail head of rail 8 outsides and following Hubei Province face match.On 1 on the chi frame on positioning groove 4 center line right sides, be respectively equipped with two orthogonal survey chi draw-in grooves 3, survey chi 2 and insert and survey in the chi draw-in grooves 3.Survey chi 2 and adopt general 155MM straight steel ruler, at ordinary times chi frame 1 with survey chi 2 and separate, when measurement wears away and chi frame 1 be used in combination.The cross section of surveying chi draw-in groove 3 is a swallow-tail form, can play certain damping action to surveying chi 2, is convenient to survey chi 2 and locatees in measuring process.A side of surveying chi draw-in groove 3 is provided with vernier graduation 7.Vernier graduation 7 satisfies reading and reaches 0.1MM, improves measuring accuracy.
Measure the rail wear process: according to the railway relevant regulations: judge that rail head of rail abrasion hurt degree only need measure the vertical abrasion and the side wear of rail head regulation point.At first, chi frame 1 is packed into rail head 8 outside rail head 8; Left index finger buttresses chi frame 1 outside, and middle finger buttresses chi frame 2 downsides, and thumb is pinned rail level, makes reference field 5 and non-acting surface in rail head 8 outsides and close the leaning on of following Hubei Province face on the chi frame 1; The right hand takes 155MM straight steel ruler 2 to insert vertical the survey in the chi draw-in groove 3, and when straight steel ruler 2 tops contact rail head 8 wearing surfaces, the vernier graduation 7 of corresponding straight steel ruler left surface gets final product reading.If the distance that preceding 8 distances with positioning groove 4 of rail head of abrasion are made as 10MM, rail head 8 medial surfaces and positioning groove 4 is made as 20MM, it promptly is vertical abrasion value that reading subtracts 10MM.With getting rail head 8 medial surfaces abrasion reading in the survey chi draw-in groove 3 of quadrat method with straight steel ruler 2 insertion levels.
