Ship reception chamber runs up and down along guide rail.
Ship reception chamber, under guidance system effect, can run along guide rail, and therefore, guide rail should have higher precision, especially
The depth of parallelism between the depth of parallelism of the orbital plane of guide rail both sides and different guide rail is bigger on the impact of ship reception chamber operation characteristic.If it is single
The orbital plane of guide rail both sides or the orbital plane parallel misalignment of adjacent rails are relatively big, and the roller stress of guider can significantly increase
Greatly, affect levelness and the traveling comfort in ship railway carriage or compartment, therefore design would generally propose strict requirements to the depth of parallelism of guide rail, and

Meter, the distance of Laser Measurement displacement meter to orbital plane, laser displacement gauge is just to orbital plane, and laser beam is vertical with orbital plane, order
Distance between two laser displacement gauges of guide rail both sides is d, and the distance of two laser displacement gauges to respective rail face is respectively
d1And d2, the distance between two orbital planes is d3, then d=d1+d2+d3；
(2) the upper and lower overall process of ship reception chamber is run, and uses electric measuring method record running every guide rail two lateral extent d1And d2
Change, owing to distance d between two laser displacement gauges immobilizes, then d3With d1、d2The variable quantity of sum is equal, symbol phase
Instead, d is being recorded1、d2After the changing value of sum, d can be obtained3Changing value, i.e. obtained guide rail parallelism deviation.
I.e. be can get the parallel misalignment of every guide rail by above-mentioned two steps, use same method, it is also possible to obtain adjacent
Two inner orbit faces of guide rail and the parallel misalignment in outside track face.
So-called laser displacement gauge, should require to select suitable model according to certainty of measurement, range, and precision typically should reach
0.1mm, installation site should control the centre at range, adjusts installation site, the screw on laser displacement gauge base for convenience
Long waist shaped hole should be used.
Range measurement uses the consecutive variations process of electric measuring method recording distance, utilizes multi-channel signal acquiring device to synchronize to adopt
The voltage signal of collection laser displacement gauge output, brings calibration coefficient into and obtains distance, and survey station is located on ship reception chamber, with ship reception chamber
Motion.
When guide rail parallelism is measured, ship reception chamber can be empty railway carriage or compartment state or carry water state, prioritizing selection sky railway carriage or compartment state, because
In less, the running of clean ship railway carriage or compartment deformation, levelness is higher, and measurement impact of adjusting the distance is less, if ship reception chamber occurs in running
Bigger inclination, is considered as ship reception chamber and tilts the impact measured of adjusting the distance, and revise.
Before carrying out guide rail parallelism measurement, guide rail surface should be cleaned, it is to avoid surface irregularities affects.
