Railway wheel online detection rail device

Abstract

The invention discloses a railway wheel online detection rail device. The railway wheel online detection rail device comprises transition region main rails, guard rails and detection region main rails. The railway wheel online detection rail device is characterized in that the transition region main rails, the guard rails and the detection region main rails are installed on guard rail tie plates in parallel. It is guaranteed that the upper surfaces of the transition region main rails, the upper surfaces of the guard rails and the upper surfaces of the detection region main rails are located at the same horizontal height. The guard rails are arranged on the inner sides of the transition region main rails and keep a distance from the transition region main rails. The detection region main rails are arranged on the outer sides of the transition region main rails, and the detection region main rails abut against the transition region main rails to form transition regions. The detection region main rails are in fastening connection with the transition region main rails through bolts in the transition regions. According to the railway wheel online detection rail device, the transition region main rails are tightly connected with the detection region main rails at equal height, so that the transition stability is ensured; the guard rails restrict wheel flanges to enable wheels not to laterally deviate too large after entering detection regions, so that the measurement accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of on-line dynamic flaw detection of railway wheels, in particular to an on-line detection track device of railway wheels. Background technique [0002] The wheel is a key component of the locomotive running system. The wheel is the part of the locomotive that is in contact with the rail. The function of the wheel is to ensure the running and steering of the locomotive on the rail. The key dimensions of the wheel shape and its integrity are directly related to driving safety. The rapid development of railway speed and the high-density operation of rolling stock have accelerated the wear of wheels. Therefore, in order to avoid the situation that the size exceeds the limit or the damaged wheel is still put into use, and to ensure the safety of the train, it is necessary to carry out dynamic online detection of the wheel. [0003] At present, the online detection of railway wheels often uses laser image measur...
