Abstract

PROBLEM TO BE SOLVED: To reduce the shaking due to the slacking of a belt by supporting both ends of the rubber conveyor belt with many belt supporting rollers, while holding it by means of a belt supporting member installed over the full length in the longitudinal direction of the belt. SOLUTION: A belt supporting member 6 is composed of a steel square pipe 6a and a self-lubricating high polymer resin liner 6b additionally attached to a top face of this square pipe 6a by bolts and nuts, and it is clamped onto a crosspiece 3 by means of an L-shaped mounting member. In addition, this belt supporting member 6 and a rubber conveyor belt 5 are contacted with each other as being locally slacked whenever a pedestrian passes through, but any bending of more than the clearance preset in the rubber conveyor belt 5 is made so as not to be produced there in terms of design. In this connection, since a top face of the high polymer resin liner 6b of the belt supporting member 6 is made to have a slight clearance so as not to come into contact with the rubber conveyor belt 5 when it is in a state of being no load, if it is driven for hours in a state of no people aboard, the high polymer resin liner 6b is preventable from abrasion.

According to the present invention, an endless tread belt is wound between a belt driving pulley and a belt tension pulley, and a plurality of belt supports are provided at both ends in the width direction of the lower surface of the forward belt. A belt support device for a moving sidewalk that supports a roller and transports a passenger riding on an upper surface of a belt, between the belt support rollers, over the entire length in the longitudinal direction of the belt, and between the belt when there is no load. A belt support device for a moving walkway, characterized in that one or more belt support members for supporting a belt when a load is applied are provided.

According to a preferred embodiment of the present invention, the belt supporting member comprises a steel mold and a self-lubricating polymer liner mounted on the upper surface of the steel mold.

Next, the operation of the present invention will be described. Both ends of the rubber belt on the moving sidewalk are supported by a large number of belt support rollers, and the passenger is transported on the upper surface of the rubber belt. Below the rubber belt, one or two or more belt support members are provided over the entire length in the longitudinal direction of the rubber belt with a slight gap provided between the rubber belt and the rubber belt. A self-lubricating polymer liner is attached to the upper surface of the belt support member. In the sidewalk where the rubber belt is wide, there are people who stop by one side of the belt and ride, and people who hurry and walk by the person who stops. At this time, when the rubber belt tries to bend significantly, the lower surface of the rubber belt is supported by the belt supporting member having good slidability, so that the walking vibration of the pedestrian is reduced, and the stopped person does not feel discomfort. Further, since the belt supporting member has a slight gap between the belt supporting member and the rubber belt, the belt supporting member does not contact the rubber belt when there is no load, does not increase the driving power, and prevents wear of the belt supporting member.
