Passenger conveyor

Abstract

Disclosed is a passenger conveyor which has excellent manufacturability of a frame body, and is easy to renew. Specifically disclosed is a passenger conveyor which is provided with: a frame body that is disposed in a building structure; platform floors that are provided to both ends in the longitudinal direction of the frame body; a footstep that is endlessly connected between the platform floors so as to circulate / turn; a drive device that drives the footstep; and railings that face right and left in the direction in which the footstep turns, wherein the frame body has a structure in which a plurality of blocks divided in the longitudinal direction are interconnected, and each of the blocks has an upper chord member, a lower chord member, a longitudinal member, and a diagonal member, and in which the longitudinal member and the diagonal member are fastened to the upper chord member and the lower chord member by reamer bolts.

Description

technical field [0001] The invention relates to passenger conveying equipment such as escalators and electric passages, and in particular to a frame structure of the passenger conveying equipment. Background technique [0002] In known passenger conveying equipment, as in Patent Document 1 figure 2 and of Patent Document 2 figure 1 and figure 2 etc., the frame body for an escalator is formed by connecting a plurality of frame body segments divided in the longitudinal direction with bolts, and each of the above frame body segments has an upper chord material and a lower chord material made of L-shaped steel. , longitudinal materials, and oblique materials, which are overlapped to form a truss shape, and the ends of the overlapped parts are connected by electric welding.

AI Technical Summary

Problems solved by technology

[0009] However, as described in the above-mentioned Patent Document 1 and Patent Document 2, in each frame section constituting the frame body, when the longitudinal material and the oblique material are welded to the upper string material and the lower string material, the upper string material and the lower string material will be The deformation caused by welding heat makes the end of the length direction of the upper chord material and the lower chord material misaligned with the end of the upper chord material and the lower chord material of the adjacent frame segment. Problems with Adjacent Frame Segments Joining Each Other

When correcting this kind of deformation, it can only be corrected by the feeling of professional technicians, and there is a problem that it is difficult to correct

[0010] In addition, since welding is used for connection, there is also a problem that it is difficult to disassemble when refurbishing.
