Description

Technical Field

[0001] The utility model relates to the technical field of track inspection trolleys, in particular to a side support mechanism for a track inspection trolley with a lifting function. Background Art

[0002] Track inspection trolley, full name track geometry detector, is a light track inspection equipment used to measure the geometry of railway tracks. It is mainly composed of a measuring trolley composed of gauge, level and other measuring devices, a fuselage prism and an industrial computer, a high-precision total station, a wireless communication unit, etc., which can detect the internal and external geometry of railway tracks. Track inspection trolleys are widely used in high-speed railways, trams, subways, and ballasted railways with high design speeds. In order to ensure that the track inspection trolley is stable when running, it is usually necessary to use a side support mechanism.

[0003] At present, most of the existing side support mechanisms support and prevent slipping by installing side wheels on both sides of the wheels that fit the side walls of the track. However, most of the existing side wheels are installed in a relatively fixed structure, and the existing tracks have different heights or obstacles that may exist on the tracks, which makes it impossible to easily adjust the existing side wheels according to different situations. The side wheels may collide with obstacles or get stuck, resulting in inaccurate detection data, requiring personnel to operate, adjust or clean them, which increases a certain workload and reduces the practicality of the side support mechanism. Therefore, we propose a side support mechanism for a track inspection trolley with a lifting function to solve the above problems. Utility Model Content
