An installation and positioning method for making the light column display screen parallel to the car window

Abstract

This application involves a installation and positioning method that enables the light to display the screen in the window, including the following steps: 1: Place the car on the track, install the tripod on the car, install the horizontal instrument on the tripod, install the limited -bound work installation onOn the car, the boundary of the boundary is vertical and the car is vertical; two: install a adjustable bracket on the side wall of the tunnel; third: adjust the adjustable bracket to make the upper and lower end of the adjustable brackets the same distance; 4: Promote the car on the track on the trackGo forward, install the next adjustable bracket, the laser wiring is located in the fixed position of the adjustable bracket, and the distance from the upper and lower end of the adjustable bracket to the limited -bound work is the same, circular in turn;Lights are installed on the beam corner steel.When this application can reduce the changes in the angle and distance of the light from the windows of the window when the train is driving on the corner section, it has made the show's display effect very good after installing the tunnel media system with a curve interval.

Description

technical field [0001] The present application relates to the field of installation of tunnel media systems, in particular to an installation and positioning method for making the light column display screen parallel to the vehicle window. Background technique [0002] The superelevation of the curved outer rail refers to the height difference between the outer rail and the inner rail on the curved track of the railway. When the rolling stock runs on a curve, centrifugal force is generated, which makes the outer rail bear greater pressure, causes severe side wear, and makes passengers feel uncomfortable, and even causes an overturning accident in serious cases. For this reason, the outer rail must be raised to a certain extent, and the centripetal force (centripetal force) generated by the body weight of the car should be used to balance the centrifugal force. The amount by which the outer rails are raised is called "superelevation". [0003] Tunnel media, also called subw...

Problems solved by technology

refer to figure 2 , is a schematic diagram of a train running on a curved road section. Due to the superhigh height of the outer rail of the tunnel, the center line of the train is inclined. At this time, the windows of the train are inclined to the light beams of the tunnel media system installed on the side wall of the tunnel, and the light beams are opposite to each other. The angle and distance of the window have changed, which seriously affects the display effect
