Abstract

The present invention relates to a speed measurement device, in particular to a wheel axle speed measurement coded disc device of a tunnel locomotive. The wheel axle speed measurement coded disc device comprises a supporting part, a coded disc protective cover and a speed measurement coded disc, and the supporting part is a strength fixing part of the whole device and comprises a clamping plate base and a connecting plate. The upper part of the clamping plate base is connected with a locomotive underframe, and the lower part is connected with the connecting plate. The lower end of the connecting plate is fixedly connected with the coded disc protective cover, and the speed measurement coded disc is installed on a locomotive wheel axle. During the test process, the coded disc protective cover wraps the speed measurement coded disc on the wheel axle, so that the device is adaptive to the tunnel locomotive dust and muddy water polluted working environments, guarantees the coded disc accurate speed measurement and the service life, at the same time, is convenient to install and disassembly on the conditions of not changing the structure of the original locomotive, and not influencing the working sate of the original locomotive, and is strong in practicality.

Description

technical field [0001] The invention relates to a speed measuring device, in particular to a wheel axle speed measuring code disc device of a tunnel locomotive. Background technique [0002] With the development of modernization in my country, locomotive operations in large tunnels occupy an important position, and the detection of locomotive running speed is of great significance in locomotive condition monitoring and operation safety. [0003] The speed detection of a large tunnel locomotive needs to directly test the speed of the wheel set of the running part, which requires the installation of a speed sensor on the wheel axle. However, the wheel set of the locomotive is a complete product, so it is necessary to design the speed measuring code disc separately, and ensure that it can be easily installed without dismantling, changing the structure of the original locomotive, and not affecting the working state of the original locomotive; at the same time, the dust 1. Sever...
