RU2003512C1 - Device for measuring contact wire position - Google Patents

Description

measures the wear of the contact wire with a bar with an electric indicator.

On a curved section of the path, the zigzag is determined by the known formula

 ± I, where h is the excess of the outer rail, sn Н I toe on a scale of 7 (or 22), and 1 ,,,,.

As the train approaches the handles 15, the trolley is removed from the rails. At the end of work on a trolley mounted on rails, the pantograph is lowered and locked, the tower

folds, lifts are removed, the tower is removed and brought into transport position (handles 15 are folded).

Feasibility

this is achieved by accelerating measurements with a minimum number of employees, and with the addition of an insulating rod with an electric indicator of wear of the contact wire, the efficiency is further enhanced.

Claims (1)

The claims DEVICE FOR MEASURING THE POSITION OF THE CONTACT WIRE, comprising a height-adjustable mast with an upper horizontal traverse intended for contact with the contact wire and a lower parallel traverse mounted on the rail chassis, a scale for measuring the height of the suspension and displacement of the contact wire, characterized in that the chassis made in the form of a biaxial trolley with retractable handles for carrying, and equipped with a pantograph and a plumb mast, folding on the chassis, while the pantograph is under the upper traverse, on which a chute is mounted with the ability to move across the contact wire, the scale for measuring the displacement of the contact wire is mounted horizontally on the mast at the level of human growth, and the scale for measuring the height of the suspension of the contact wire, calibrated from top to bottom from the minimum allowable height of the suspension vertically on a plumb line with the intersection of the displacement scale / ( srggs 9 g
