摘要:
An apparatus for measuring a displacement of a railroad includes a pair of rail fixing members 100 fixed to enclose a lower part of one rail 10, and installed to be spaced from each other; a lengthwise sensor casing 200a installed between the pair of rail fixing members 100; and an angle sensor installed at the lengthwise sensor casing 200a so as to measure a change of an angle between the pair of rail fixing members 100. With such a configuration, the present invention can be applied to a structure of railroad ties formed of a concrete material. Further, data can be obtained with high reliability, since a displacement of the rail is directly measured.
摘要:
A guide method for guiding a device that is designed to insert elements into the ground in order to make a structure, the method comprising the following steps: establishing topographical points and determining the coordinates of these points in an X, Y, Z frame of reference; putting a measuring station in place in the vicinity of the structure and determining the X, Y, Z position of said measuring station with reference to one or more topographical points; determining, by means of said measuring station, the distance and the angle between said insertion device and the measuring station; calculating the position of the device by means of the measured distance and the known position of the measuring station; displacing the insertion device so that said elements are in register on the insertion axis with given positions where the elements are to be inserted into the ground.

A train rail alignment and distance system. The train rail alignment and distance system is a durable, highly accurate, portable electronic measurement system that is used for determining both rail inclination and distance between substantially parallel train rail sections during the processes of railway construction, maintenance, and monitoring. The system is designed to work accurately across a wide temperature range and in extreme weather conditions. It is designed to be easily manufactured, configured and maintained. The system also includes several optional integrated features and functions such as: field calibration, factory configuration, GPS and/or USB integration, PC and/or Internet-based communications, and data logging, data storage, and data analysis capabilities.

The new instrument is a three piece frame which folds into a compact, hand carried device and when opened forms a track spanning frame. In its open position the frame carries on its midsection an electronic levelmeter and the track gage meter or indicator.The main frame consists of four arms. Two of these arms are hinged to fold on themselves for carrying and opening into a straight line for making measurements of gage and level. The other two arms fold back onto the first two for carrying and open at a predetermined angle to support the first mentioned arms in a perpendicular relationship to the track being observed.Under the three outer ends of the arms are feeler contacts. The two on the angled arms are fixed to ride on the inner edge of one of the tracks being measured. A third feeler contact is carried under the end of the single and oppositely extended arm. This third contact is moveable to contact the inner edge of the second track and is coupled to a gage monitoring device to monitor the gage of the two rails under the three arms of the device of my invention, level monitoring means is carried on one of the arms.
