Abstract
The invention relates to a track direction vector gauge metering and detecting device for a track measuring instrument. The track measuring instrument needs to accurately measure the track direction vector gauge of a steel rail in a walking process in order to realize comprehensive detection of the rail smoothness. The track direction vector gauge metering and detecting device comprises a measuring wheel axle and a measuring wheel arranged on the measuring wheel axle, wherein a fixing rod is arranged at the top end of the measuring wheel axle; a vector gauge measuring main scale which is vertical to the fixing rod is fixed on one side of a walking wheel of the fixing rod; a walking wheel protection cover is arranged above the walking wheel; an open groove is formed in the top of the walking wheel protection cover; the vector gauge measuring main scale is positioned in the open groove in the top of the walking wheel protection cover; a vector gauge measuring auxiliary scale is arranged on the groove edge of the vector gauge measuring main scale corresponding to one side of the open groove in the top of the walking wheel protection cover. A relevant measuring device is arranged at the measuring wheel of the track measuring instrument, so that accurate measurement of the track direction vector gauge through the measuring wheel is realized, and spatial conflict with a walking wheel structure in a limited space is avoided. The track direction vector gauge metering and detecting device is compact and reasonable in structure, and is accurate and reliable in measurement.
Description
Technical field
the invention belongs to railroad survey technical field, be specifically related to a kind of orbit measurement tradition to vector distance measuring and testing device.
Background technology
The smooth degree of railroad track refers to that the height that track is occurred rises and falls and left and right offsets, and affects the normal traveling of train because train orbits and the change of track bed for a long time.Along with improving constantly of train running speed, for realizing safety and the comfortableness of train operation, particularly the ride comfort of high speed railway track directly affects the safety of bullet train with steady, the design and construction of circuit must accomplish high ride, railroad requires more and more higher to railway irregularity state parameter, therefore particularly seems important to the detection of rail smooth degree with maintenance.
At present, the detection for railroad track smooth degree adopts the mode of track geometry status measuring instrument to carry out more, i.e. rail measuring apparatus, and this instrument need be measured to vector distance accurately to the Rail in walking process, to realize the comprehensive detection to orbital forcing.
