Description

Wheel radial runout measuring device

Technical Field

The utility model relates to a rail transit wheel detection mechanism, in particular to a device for measuring radial runout of a rail transit wheel, which mainly uses the top of a wheel rim and the inner side surface of the wheel rim as measurement references, and the device is tightly attached to the inner side surface of the wheel rim and slides along the top of the wheel rim, so that the radial runout parameter value of the tread of the wheel can be measured.

Background

The wheels are very important running components of rail transit rolling stock, and in order to ensure the running safety and stability of the rolling stock, the wheels need to be turned on at regular intervals, and the states and various parameters of the wheels are checked and measured. The measured parameters comprise parameters such as the diameter of the wheel, radial runout, the height of the wheel rim, the thickness of the wheel rim and the like. The wheel radial runout parameter reflects the condition of wheel out-of-round, and excessive radial runout can cause severe wheel rail vibration, so that train components are damaged, passenger comfort is reduced, safety and service life of a train and rail facilities are influenced, and even an axle is broken and broken, so that serious accidents are caused.

The measuring device for the radial runout of the wheels is mainly divided into two types at present, namely, the measuring device is arranged beside a line rail of an access section, and when a train passes through the device, mechanical contact type or laser non-contact type detection is carried out. The measuring device needs to reserve an installation interface, lay cables and the like beside the track in the early stage, and has higher equipment purchasing and installation cost and the like; when in use, a train needs to pass through the stock way, and the measuring range is only at the rolling circle, so that certain limitation exists; the method is mainly suitable for normalized detection when the train enters and exits the warehouse. One type is a measuring device used in a maintenance warehouse, mainly by lifting a wheel pair axle box, so that the wheels can be in a free rotation state, and simultaneously fixing a measuring device (a measuring needle, a measuring disc or laser), and rotating the wheels to perform measurement, such as a non-drop wheel lathe. The measuring mode needs to adjust the train to a specific stock way, and then the wheel set weighing several tons can be measured after being lifted, so that the measuring mode consumes manpower and material resources, is long in use and poor in safety, and is mainly applied to daily regular detection of the train and analysis and detection of abnormal sound problems of the wheels.

Under the background, the simple wheel radial runout measuring device is designed, and the device is necessary to be applied to analysis and detection of abnormal noise of daily wheels.
