The present invention relates to a drive rail of the escalator, and more particularly to a drive rail of the escalator to prevent the left and right flow of the drive roller to improve the ride comfort and to be assembled by fitting the bolt to the lower part of the drive rail.

As shown in FIG. 1 and FIG. 2, the mounting structure of the rail of the general escalator is secured by connecting the upper frame 1a and the lower frame 1d of the truss 1 with the vertical reinforcing bar 2a. In (2a), traveling rails are provided for guiding the rollers of the steps such as the backward driving rail 3a, the trailing track 4a, the return driving rail 5a, and the trailing track 6a. In detail, in FIG. 2, the upper frames la and 1b are reinforced with the lower frames 1d and 1c by the vertical reinforcing bars 2a and 2b, respectively, and the horizontal reinforcing bars 8 respectively. Vertical reinforcing bar (2a) is reinforced with the vertical reinforcing bar (2b), and the reinforcing bar (8), the backward drive rail (3a), (3b), the path following the rail (4a), (4b) and the return track Brackets 9a and 9b each having a structure in which 6b) can be installed are fixedly installed.

FIG. 3 is a detailed view of part "B" of FIG. 2 showing the structure and installation state of the conventional route driving rail 3a, and the route driving rail 3a for fixing the yellow route driving rail 3a to the bracket 9a. Square washer (15), a backward driving rail (covered with long holes of the bracket (9a) and the only hole of the stud bolt (10) to cover the stud bolt (10) and nut (11) welded to the side of the In order to support the lower surface of 3a) and fix it to the transverse reinforcing bar 8, the stud bolt 12 and the stud bolt 12 welded to the lower surface of the road drive rail 3a are fixed to the transverse reinforcing bar 8 Square washers (14a) and (14b) and nuts (13a) and (13b). The backward driving rails 3a and 3b are respectively installed on the brackets 9a and 9b so as to face each other with a "L" shaped cross section as shown in FIG.

When the driver of the escalator is operated, the drive chains 18a and 18b which are fixed to both sides of the drive roller shaft 17 and connected to the drive are driven. Therefore, the driving rollers 16a and 16b rotate along the running surface H of the backward driving rails 3a and 3b, respectively, but the backward driving rails 3a and 3b have an L shape. Since it has a cross section, a gap is formed between the inner surface (“I” portion) and the side surfaces of the driving rollers 16a and 16b to generate left and right flow during driving.

In addition, the installation and adjustment method of the backward drive rail (3a) is welded stud bolts (10), (12) without the bolt head, such as the third way in the side and the lower part when manufacturing the backward drive rail (3a) and the stud bolt ( 10) insert the square washer with the bolt hole (5) after inserting it into the long hole of the bracket (9a) and tighten it with the nut (11) in the position where the stud bolt (10) is inserted into the long hole of the bracket (9a).
