Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the structure of a circular escalator.

A circular escalator has an arc-shaped main frame that is inclined in the horizontal projection plane, an endless conveyance path is formed on the main frame, and a large number of steps with fan-shaped planes are arranged in succession on the conveyance path. They are connected to each other and are operated in circulation on the conveyance path. However, the reversing mechanism for reversing the steps at the reversing portion of the conveyor path, which has fan-shaped planes and are connected to each other, becomes complicated.

Reversing the steps required a large space and the main frame was large, which resulted in a problem that restricted the installation of a 9-circular escalator.

This invention solves the above-mentioned drawbacks, and allows the steps to be reversed with a simple configuration.

Can be installed in a small space 1. It is intended to provide a C circular Niscare bamboo.

can be done. Therefore, a simple reversing machine 41fIm
&τyotsu' The space for reversing the C steps (3) can be made smaller, the main frame f11 can be made smaller, and a small circular ethno-moon/-yu can be obtained with fewer restrictions on installation space. . In addition, as the step (3) moves, the adjustment loan (

) The position of the arm (8) relative to the side surface (6b) is regulated.

On the other hand, the rail ('i! (7) is manufactured in a precise manner, especially on the outward journey (2a), and it needs to be set at a predetermined position, but there is an error in this)1. and steps (

If a gap occurs, the position of the arm (8) relative to the step (3) can be adjusted by adjusting the adjustment rail (move the IQ position to the specified outward path (2a)) and set the displacement -V''C. By changing 1if, the steps (3) can be moved while maintaining their normal mutual positions.

1a top M5? As explained above, the present invention connects the inner side of the circular arc of the conveyance path of the step, which is provided in the conveyance path that is arc-shaped and oblique in the horizontal projection plane, to the inner chain via a shaft pivotally connected to the step. It is connected to the outer chain at a position closer to the tread surface than the connection part with the inner chain via the connecting pin of the arm pivotally attached to the two outer axes of the conveyor path arc, and II+i
Adjust the position of t with respect to the step. Guide the roller Jl.
'z-'gpa! In addition to being restricted by the rail, the conveyance path θ) is at the reversing section (C), and the speed between the steps and the Tsukuda chain is 1 (χ, Tll1l and qp, and a reversal (P mechanism) that performs a reversal operation according to the Nagi5 locus on the step itself L and the cylindrical surface. It is possible to make the main frame smaller by reversing it in the r-space, easing the constraints imposed by the installation space, and also adjusting the guide rail of the steps through the arm with the adjustment roller IRI7i1 alignment rail. It is possible to correct abnormalities such as 111i + protrusion between steps and gap I C1 due to installation f dimension errors, thereby realizing a highly safe circular escalator.
