Problems solved by technology

[0004] However, when the supporting metal member deviates in the direction away from the supporting beam, the supporting pitch of the supporting metal member increases, so the bending moment received by the supporting metal member increases.

Embodiment approach 1

[0037] figure 1 It is a side view which shows the main frame of the escalator in Embodiment 1 of this invention. In the figure, between the lower structure 1 and the upper structure 2 disposed at a position higher than the lower structure 1, a main frame (framework) 3 of the escalator is erected. A plurality of steps (not shown) connected in a ring shape are supported on the main frame 3 . Each step circulates between the lower structure 1 and the upper structure 2 by the driving force of a driving machine (not shown) provided in the main frame 3 .

[0038] The main frame 3 has: a main frame body 4 with one end in the longitudinal direction facing the lower structure 1 and the other end in the longitudinal direction facing the upper structure 2; The lower supporting metal member (supporting member) 5; the upper supporting metal member (supporting member) 6 provided on the longitudinal upper end (the other longitudinal end) of the main frame body 4.

Embodiment approach 2

[0061] In Embodiment 1, the reinforcing member 15 is a rectangular plate, but the reinforcing member 15 may be a triangular plate.

[0062] which is, Figure 7 It is a front view which shows the longitudinal direction upper end part of the main frame of the escalator concerning Embodiment 2 of this invention. in addition, Figure 7 is the same as that of Embodiment 1 image 3 corresponding figure. In the figure, each reinforcing member 15 is a triangular plate. In addition, the reinforcing member 15 is fixed only to the upper vertical member 12 and the vertical plate portion 6 a among the upper vertical member 12 , the vertical plate portion 6 a of the upper support metal member 6 , and the main frame lower member 14 . That is, the reinforcing member 15 is not fixed to the main frame lower member 14 but is arranged away from the main frame lower member 14 . The structure of the lower end portion of the main frame body 4 in the longitudinal direction is also the same as th...

Embodiment approach 3

[0067] In Embodiment 1, the reinforcement member 15 is fixed to the support metal member, the vertical member, and the main frame lower member in a state where a part of the reinforcement member 15 overlaps with the portion of the vertical member that overlaps the support metal member. The reinforcing member 15 is fixed to the supporting metal member and the main frame lower member so as to overlap the portion of the vertical member overlapping the supporting metal member.

[0068] which is, Figure 8It is a front view which shows the longitudinal direction upper end part of the main frame of the escalator concerning Embodiment 3 of this invention. in addition, Figure 8 is the same as that of Embodiment 1 image 3 corresponding figure. Each upper end portion of each upper vertical member 12 overlaps both end portions of the upper support metal member 6 when viewed along the longitudinal direction of the main frame body 4 . Each reinforcing member 15 is arranged away from ...

Abstract

The present invention provides a passenger conveyer main frame which can increase intensity and can be easily arranged. The passenger conveyer main frame (3) is provided with a main frame body (4), lower supporting metal parts (5) and upper supporting metal parts (6) arranged on two end parts of the length direction of the main frame body (4). The main frame body (4) is provide with upper longitudinal parts (12) with the upper supporting metal parts (6), and reinforcing parts (15) fixed on the upper longitudinal parts (12) and used for reinforcing the upper longitudinal parts (12). The reinforcing parts (15) are fixed on the upper longitudinal parts (12) in a way that parts of the upper longitudinal parts (12), which are overlapped with the upper supporting metal parts (6), are overlapped with edges of parts of the upper longitudinal parts (12), which are separated from the upper supporting metal parts (6).

Description

technical field [0001] The present invention relates to the main frame of passenger conveyors (eg, escalators, moving walkways, etc.). Background technique [0002] Usually, the main frame of a passenger conveyor is installed so that it may be bridged between support beams which are respectively installed on a pair of structures separated from each other. Support metal members are fixed to both ends of the main frame. The main frame is erected between the supporting beams in a state where the supporting metal members are placed on the supporting beams. Therefore, the entire load of the passenger conveyor is exerted on the supporting metal parts. [0003] In addition, in passenger conveyors, only one support metal member may be fixed to the support beam, and the other support metal member may be placed as it is without being fixed to the support beam, and the main frame may be installed in such a state. In such a passenger conveyor, even if a deflection of the main frame o...
