Magnetic suspension contact rail measuring instrument
PendingCN119099680Ameasure impactImprove operational convenienceStands/trestlesUsing optical meansMeasuring instrumentMechanical engineering
The invention discloses a magnetic suspension contact rail measuring instrument which comprises a rack, a positioning mechanism and a measuring mechanism, the measuring instrument is fixed to an F rail through the positioning mechanism so as to achieve measuring and positioning of the measuring instrument, a first supporting part is located on one side of a current collecting face of a contact rail, and a first laser displacement sensor is arranged on the first supporting part in a sliding mode. Therefore, the pull-out value and the rail surface angle of the contact rail can be measured. Correspondingly, the second supporting part is located below the contact rail, and the second laser displacement sensor is arranged on the second supporting part in a sliding mode so as to measure the guide height value of the contact rail. The first laser displacement sensor and the second laser displacement sensor are arranged in a sliding mode, multi-point measurement is facilitated, multiple sets of data are obtained, and the accuracy of the measurement result is further improved. The rack provides stable support for the positioning mechanism and the measuring mechanism, a sectional combined structure is adopted, one end of the positioning mechanism is connected with the first supporting part, a protective cover is prevented from affecting measurement of the contact rail, and the overall structure of the measuring instrument is simplified.
