Problems solved by technology

[0006] However, setting up two sets of chain slack absorbing devices and chain slack detecting devices means that in addition to setting up two sets of sliding members and two sets of detecting devices for detecting the displacement of the sliding members, it is also necessary to set up two sets for pressing the sliding members. As a result, it is difficult to install the chain slack absorbing device and the chain slack detecting device in the narrow space of the passenger conveyor in terms of design, and the installation work becomes difficult

[0037] The escalator 1 can be roughly divided into a frame body 2 arranged across the upper and lower floors, a plurality of circularly connected steps 3 that can move freely in the frame body 2 under the guidance of the frame body 2, and be vertically arranged at the width of the frame body 2. The railing 4 on both sides of the direction and the ring-shaped moving handrail 5 that moves under the guidance of the railing 4 periphery.

[0038] The steps 3 are guided so that, on the outbound side, at the upper horizontal portion 2A, the middle inclined portion 2B, and the lower horizontal portion 2C of the housing 2, the passenger standing surfaces are maintained in a horizontal state. In addition, the steps 3 are configured to circulate in the housing 2 by winding the step chain 6 around a terminal gear 8 of a driving device 7 and driving the terminal gear 8 with a prime mover 9 .

[0039] On the other hand, the moving handrail 5 is driven by the handrail driving device 10 to mo...

Abstract

The present invention provides a passenger conveyor which can operate reversely. The passenger conveyor can reduce the number of elements, makes that a chain flab absorbing device and a chain flag detecting device are installed in the narrow space of passenger conveyor in designing, and facilitates the installing operation. In the passenger conveyor according to the invention, a common elastic body (25) is used for pushing sliding components (22A, 22B) to cause that the sliding components (22A, 22B) respectively contact the driving chain (19) which enters the side of driving trolleys (11A-11C) of pressure clamping movable handrail (5) and the driving chain (19) at the coming-out side of driving trolleys (11A-11C) with sliding contact. Furthermore chain flab detecting devices (27A, 27B) which detect the displacement amounts of sliding components (22A, 22B) for detecting the flab of driving chain (19).

Description

technical field [0001] The present invention relates to a passenger conveying device including an escalator that produces a level difference on the passenger standing surface of an inclined section and an electric channel that does not produce a level difference on the passenger standing surface, and particularly relates to a reliable driving system for a moving handrail Passenger transport equipment with improved performance. Background technique [0002] The driving system of the moving handrail of the passenger conveying equipment is generally configured to drive the driving rollers clamping the moving handrail with pressure through a driving chain with power from a driving device driving the passenger standing surface. And, in order to improve the reliability of the driving system of the moving handrail, and in order to detect the situation that the driving chain is elongated or cut as soon as possible, as shown in Patent Document 1, a chain slack absorbing device for th...
