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 is and in particular to a kind of orbit measurement tradition fills to vector distance gauge check
Put.
Background technology
The smooth degree of railroad track refers to the change orbiting for a long time with track bed due to train, so that track is gone out
Existing height rises and falls and left and right skew, the normally travel of impact train.With the continuous improvement of train running speed, for realizing row
Security and comfortableness that car runs, the ride comfort of particularly high speed railway track directly affects the safety peace of bullet train
Surely, the design and construction of circuit must accomplish high ride, and railroad requires more and more higher to railway irregularity state parameter,
Therefore the detection to rail smooth degree particularly seems important with safeguarding.
How detection currently for railroad track smooth degree is carried out by the way of track geometry status measuring instrument, i.e. rail
Road measuring instrument, this instrument accurately need to be measured to vector distance to the rail rail in walking process, to realize to orbital forcing
Comprehensive detection.
