Technical Field
The invention relates to a conveying system, in particular to an unpowered passenger stair-descending baggage conveying system.
Background
In public places where passengers are concentrated, such as railway stations, subway stations and the like, a large number of stairs for going downwards are provided, such as stairs from a platform bridge to a train parking platform of a railway station, stairs from the train parking platform to an exit tunnel and the like, and the stairs of the subway station are also mainly used for going downwards and are equipped with escalators for going upwards. When going down stairs, many passengers often carry various kinds of baggage, some of which have a weight of tens of kilograms. In order to facilitate passengers to take luggage to go down stairs, there are two methods: the method is that an escalator is arranged on one side of a stair. The escalator is a conveying device driven by a motor, and can convey passengers and luggage to the lower part of stairs synchronously, the method is efficient and safer, most of the down stairs are provided with the escalator for the railway stations with large urban passenger flow, but the escalator is expensive, has large power consumption and high operation cost, so that in order to save cost, some newly-built middle railway stations with not large passenger flow only select part of the down stairs to be configured with the escalator, and a plurality of stairs only have the up escalator without descending, which is also mainly the reason; the second method is to build a slide ramp on one side of the stairs, wherein the slide ramp is built on the middle and small-sized railway stations and part of large-sized railway stations, especially on the downstairs of the railway stations built earlier. The sliding ramp is only suitable for sliding luggage with wheels (such as a luggage case and a small trailer), and when the luggage goes down stairs, the luggage case is placed on the ramp and slowly rolls downwards while being forcibly pulled upwards. The sliding ramp has low manufacturing cost and no running cost, but has obvious defects that firstly, only the luggage with wheels can slide; secondly, the rolling friction force is small, so that the passenger can control the gliding speed only by balancing the gliding force with a large pulling force; thirdly, because the walking route of the passengers is parallel to the ramp and is separated from the ramp by a certain distance, the passengers need to extend hands to the ramp position to pull the luggage hard, and the luggage often slides out of the ramp or the passengers lose balance and fall down due to hard force, so that most passengers prefer to carry the luggage to go downstairs and do not prefer to use the sliding ramp.
