Description

Guiding structure suitable for moving sidewalk pedal at inclined section

Technical Field

The patent relates to the technical field of travelators, in particular to a guiding structure suitable for a travelator pedal in an inclined section.

Background

With the development and progress of society, escalators and moving walkways have been commonly used, and become an indispensable device for people to live conveniently. In places requiring carts, such as airports, supermarkets, shopping squares, etc., travelators are widely used. Smooth running of the travelator is important to comfort and safety of passengers when riding a ladder.

The pedal is a main moving part of the moving sidewalk, and the moving sidewalk can drive the pedal to circularly run to convey passengers or trolleys through the pedal belt. When the pedal chain moves to the inclined return section, as the return section guide rail has no limit function, the movement track deviation possibly occurs during the running of the pedal chain, so that the pedal chain is deviated, the pedal shakes left and right, the running is unstable, and even the condition that the pedal chain is separated from the guide rail occurs, so that the safety and comfort of riding passengers are reduced.

Through setting up the guide surface for wheel roll and footboard chain can get into smoothly the passageway that forms between guide rail and the supporting rail when getting into the guide structure. If the guide surface is not provided, if the pedal is slightly deviated before entering the guide structure, the roller or the pedal chain may directly collide with the end of the guide part of the support rail, so that the automatic sidewalk is blocked, and even a safety accident occurs.

Further preferably, the angle between the guide surface and the extending direction of the guide part is 15 ° -80 °.

Still preferably, an included angle between the guide surface and the extending direction of the guide portion is 30 ° -60 °. The guide surface is guided on the one hand, and on the other hand, the pedal chain below the guide surface can be limited, so that the pedal chain is prevented from jumping upwards.

Further preferably, the guide surface is arranged in an arc shape.

More preferably, the guide portion is located above the tread chain. The lower part of the guiding part is positioned at the side edge of the roller and used for limiting the roller and preventing the pedal chain from jumping upwards.

Preferably, a buffer layer is arranged on one side surface of the guide rail, which is close to the roller. The buffer layer is used for playing the cushioning effect when gyro wheel or footboard chain touch the guided way on the one hand, in time will receive the atress dispersion, guarantees the stability of structure, promotes the travelling comfort, on the other hand can the noise reduction.

More preferably, the material of the buffer layer is an elastic polymer material, such as rubber, thermoplastic elastomer TPE, polyvinyl chloride, etc.

Preferably, the guide rails are arranged at intervals or continuously on the inclined section of the travelator.

Compared with the prior art, the invention has the following advantages: the guiding structure for the inclined section of the pedal of the automatic sidewalk has reasonable structural design, is safe and reliable, can realize guiding of the pedal, ensures that the pedal always moves in the same linear direction, and prevents the pedal chain from deflecting to cause the pedal to shake left and right; when the pedal moves at the inclined return section, if the roller and the pedal chain deviate, the guide structure can timely guide the pedal to move in a normal track, so that the unstable condition that the pedal shakes left and right is avoided, the comfort and the safety of people riding on the moving sidewalk are improved, and the guide structure can also effectively prevent the occurrence of the jumping-up condition of the sidewalk pedal.
