[0049] Combined diagram Figure 5 , Figure 8 , Fig.10 , Fig.18 and Fig.19 As shown, Fig.18 The present invention provides a schematic diagram of the operation of measuring the vertical distance of the platform door installation limit of a rail platform door system limit measurement rail vehicle. When working, the adjusting screw 101 is screwed to move the vertical moving bracket 132, the adjusting handle 124 is screwed to move the horizontal shift rod 121, so that the measuring rod 1321 is placed between the installation gap between the platform door 31 and the platform board 32, thereby eliminating the horizontal deviation between the platform door 31 and the center of the track 20 during vertical distance measurement. The measuring rod 1321 is controlled to abut against the bottom of the platform door 31 and the top of the column of the platform board 32 located below the platform door 31, respectively, and the scale of the vertical plate ruler 134 pointed by the pointer of the corresponding second pointer member 133 and the scale of the horizontal plate ruler 114 pointed by the pointer of the first pointer member 123 are recorded, so as to realize the vertical distance measurement of the installation limit of the platform door 31, and facilitate the accurate installation of the platform door 31. The vehicle body 11 is pushed to make the rail vehicle 10 move along the track 20 to measure the limit of each position of the track 20.

[0050] In summary, the present invention provides a rail platform door system limit measurement rail vehicle with a guide wheel assembly installed at the bottom of the lower cross beam of the vehicle body so that the vehicle body can move along the track to perform continuous measurement, and the measurement efficiency is high. At the same time, the guide wheel assembly can be adjusted according to the track spacing, and the application range is wide. By setting the vehicle body, it can be achieved that the balance and stability are maintained when the track moves, and the guide wheel assembly plays a role of pushing and guiding; a horizontal ruler is set on the upper cross beam of the vehicle body, and a horizontal shift rod assembly is set above the upper cross beam, one end of the horizontal shift rod extends out of the vehicle body and the horizontal shift rod can adjust the position of the horizontal shift rod by adjusting the handle, so that the horizontal shift rod can move along the length direction of the upper cross beam, and the pointer of the first pointer member moves on the scale of the horizontal ruler with the movement of the horizontal shift rod, so that horizontal distance measurement can be achieved; the vertical shift rod assembly is set at one end of the horizontal shift rod, The vertical movable bracket is vertically installed on the end of the horizontal shift rod through a support, and the adjusting screw enables the vertical movable bracket to move along the length direction of the vertical mark rod of the support. A vertical ruler is provided on the vertical mark rod, so that the pointer of the second pointer part moves on the scale of the vertical ruler with the movement of the vertical movable bracket, so as to realize vertical distance measurement. Moreover, through the cooperation of the horizontal shift rod assembly and the vertical shift rod assembly, the horizontal deviation between the platform door and the center of the track is eliminated during vertical distance measurement, and the vertical deviation between the top surface of the track and the platform is eliminated during horizontal distance measurement. Moreover, the platform and the track can be measured in the horizontal and vertical directions without manual hand tools. The detection accuracy is high, and there is no need for a review process, which effectively shortens the construction period. The gap interval between the platform door and the column of the platform board can be accurately measured, which is convenient for the accurate installation of the platform door.
