A track detector

Abstract

The invention provides a track detector. The track detector is used for detecting corresponding data of a track, comprises a main beam mounted on the track and a traveling wheel assembly which slidesalong the track, and further comprises a secondary beam, at least one traveling wheel adjusting assembly, a distance measuring assembly and a driving assembly. The secondary beam is parallel to the track and connected with the bottom of one end of the main beam; the traveling wheel adjusting assemblies are disposed at the bottom of the end, away from the secondary beam, of the main beam; the distance measuring assembly is disposed below the main beam and adjacent to the traveling wheel adjusting assemblies, and a signal transmitting point of the distance measuring assembly faces the travelingwheel adjusting assemblies, the driving assembly is disposed on the secondary beam for driving the traveling wheel assemblies to move. The traveling wheel assembly comprises left traveling wheel setsand right traveling wheel sets, the right traveling wheel sets are separately disposed at both ends of the secondary beam and are driven by the driving assembly to slide along a right track; the lefttravelling wheel sets are disposed on the travel wheel adjusting assemblies and slide along a left track; and the travelling wheel adjusting assemblies are used for enabling the left travelling wheelsets to slide by tightly attaching to the left track. The travelling wheel sets are attached to the track by the travelling wheel adjusting assemblies to improve the gauge measurement accuracy.

Description

technical field [0001] The invention relates to the field of railway track detection, in particular to a track detection instrument. Background technique [0002] In the stage of railway construction, after the laying of the railway track is completed, it is necessary to detect the absolute position and relative position of the track, and adjust the position that does not meet the design requirements to ensure the safe and comfortable operation of the train. During the long-term operation of the railway, the track will change due to long-term use wear, subgrade settlement, loose fasteners and other reasons, resulting in changes in the absolute and relative state of the local position of the track. These changes will seriously affect the safety and comfort of train operation, and these improvements must be detected and adjusted, and the gauge is one of the important detection objects. [0003] The gauge refers to the distance between the gauge points at 16mm below the 120 wo...
