Abstract

The invention discloses a measuring apparatus for corrugation of a railway curve upper-part side grinding steel rail. A supporting frame with a measuring arm is erected on the steel rail; the measuring arm is mounted on the supporting frame in a sliding manner, and can longitudinally slide along the steel rail; a displacement probe is mounted on the measuring arm, and the angle of the displacementprobe on the surface of the steel rail can be adjusted; a measuring rolling wheel is mounted at the end part of the displacement probe, and is in contact with a rail head of the curve upper-part sidegrinding steel rail; the steel rail displacement probe moves along with the measuring arm in the direction of the steel rail, and the measuring rolling wheel rolls along the rail head of the curve upper-part side grinding steel rail; and in the moving process of the displacement probe, the movement capacity of the displacement probe is detected in a real-time manner by a displacement sensor mounted at the end part of the displacement probe, so that corrugation depth at a measured angle on the surface of the steel rail is obtained. Through the adoption of the measuring apparatus disclosed by the invention, the corrugation depth of the steel rail at different positions and angles, on the inner side of the curve side grinding steel rail can be detected, the curve steel rail grinding operation can be effectively guided, and thorough removing of the corrugation on the surface of the steel rail is facilitated.

Description

technical field

[0001] The invention relates to the field of engineering technology, specifically, it is a method to detect the rail corrugation depth at different angles of the rail surface by optimizing the structure of the measuring arm, especially the rail corrugation depth at different angles of the strand side grinding rail surface on the curve, to form rail corrugation. Grinding waveform diagram, so as to effectively guide the rail wave grinding operation. Background technique

[0002] The railway is the main artery of transportation, which plays a very important role in the development of the national economy. With the increase of the speed of the railway, the increase of the transport volume, and the diversification of the operating models, the loads on the rails are becoming more and more complex, resulting in wave wear on the rails, rail Surface scratches, rail surface peeling, rail side wear, cracks and rail head crushing and other diseases have a serious impact ...

Embodiment Construction

[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0025] The rail corrugation measuring instrument of the present invention includes a measuring arm 1 and a displacement probe 2, such as figure 1 Shown; through the support frame 3 erected on the rail rail head.

[0026] Described support frame 3 comprises side frame 301, front base 302, rear base 303 and connecting rod 304, as figure 2 shown. Wherein, the front base 302 and the rear base 303 are connected to each other through side frames 301 arranged along the direction of the rail; meanwhile, the front base 302 and the rear base 303 are connected to each other through a connecting rod 304 arranged along the direction of the rail. The connecting rod 304 stabilizes the structure of the supporting frame and facilitates the handling of the measuring instrument. The bottom of the front base 302 and the bottom of the rear base 303 are provided with a slot 30...
