Description

A kind of device measuring the static geometric parameter of railroad track
Art
The present invention relates to a kind of railway track measurement device, particularly relate to a kind of device measuring the static geometric parameter of railroad track.
Background technology
Theory analysis both domestic and external and experimental data show, along with the raising of train speed, the impact load of wheel to rail that the uneven compliance (comprising rail surface, work plane) of rail longitudinal section causes sharply increases, rail fracture, track component not only may be caused to lose efficacy, and easily cause rolling stock component hurt.The long term of these huge wheel rail forces also will make ballast aggregate breakage, plate knot of ballast bed, rise soil, and destroy the elasticity of railway roadbed and stability, finally cause wavelength and the larger track irregularity of amplitude, affect traffic safety and ride comfort.
Therefore, the ride comfort of domestic and international railway maintenance department to rail rail level is all paid much attention to, and should control intermediate waves irregularity, control long wave irregularity again by the outside geometric parameter of maintenance railroad track by maintenance railroad track inner geometry parameter.At present, efficiency only 300 meters/skylight point (4 hours) measured by the checkout equipment that railway maintenance department generally adopts, also lack a kind of high accuracy, high efficiency checkout equipment, seriously constrain the maintenance repair efficiency of rail track, high-speed railway normal operation and maintenance are exerted a certain influence.
Summary of the invention
The present invention is to solve the inefficient problem of the static geometric parameter checkout equipment of existing railroad track, provides a kind of device measuring the static geometric parameter of railroad track.
The present invention is achieved by the following technical solutions: a kind of device measuring the static geometric parameter of railroad track, comprise Inertial Measurement Unit, gauge measuring unit, measurement of dip angle unit, mileage measuring unit, total powerstation, prism, data processing unit, described Inertial Measurement Unit, gauge measuring unit, measurement of dip angle unit, mileage measuring unit, total powerstation are connected with data processing unit respectively.
Described Inertial Measurement Unit, gauge measuring unit, measurement of dip angle unit, mileage measuring unit, total powerstation, data processing unit are arranged on measurement mechanism respectively.
Described prism is be positioned on the fixed bearing of track both sides known parameters.
The static geometric parameter detection method of railroad track provided by the invention, brings up to 6 kilometers/skylight point (4 hours), substantially increases railway overhaul efficiency, for the safe operation of high-speed railway provides safeguard by measurement efficiency.
