Description
Technical Field
The invention relates to the technical field of elevators, in particular to a vertical lifting and horizontal moving cordless elevator system.
Background
In order to improve the living quality of the building without electricity, the elevator is urgently installed, so that governments in various places have developed relevant encouragement policies, and the state also provides clear support in the policy of 'old community transformation', but the resistance is met in the actual operation process. Resistance comes from two main aspects, one is financing and one is frustration for lower-level residents.
In reality, elevators are additionally installed in a building without an elevator, most of the elevators are used on the outer side of an existing passageway, and a vertical shaft is newly built for installing a vertical elevator; because the elevator shaft is arranged at the outer side of the passageway of the corridor, part of the travel passageway is occupied, and people can not travel smoothly; in addition, in order to reserve a safe passage, the elevator shaft is forced to be far away from the outer wall of the building, so that a space must be formed between the newly-built elevator shaft and the reconstructed elevator platform, and therefore, a connecting gallery bridge needs to be repeatedly arranged between the newly-built elevator shaft and the reconstructed elevator platform to meet the elevator riding requirements of people, so that the self weight of the shaft is increased, and the construction cost is increased; moreover, various pipe and path facilities are mostly arranged outside the building entrance, and the building elevator shaft is difficult to avoid due to harsh requirements, so that the pipe and path facilities need to be rebuilt again, and finally the construction cost is high. The price for purchasing a vertical lifting elevator added for six-storey buildings is about ten-ten thousand yuan, but the cost for building a hoistway is three to five times of the price for purchasing the elevator, so that the high capital construction cost makes fund raising difficult. In addition, due to the fact that the arrangement of the well way shields partial ventilation and lighting of the low-rise residents, the privacy right of the low-rise residents is also influenced, the rights and interests of the low-rise residents who do not need the elevator are damaged, and therefore the low-rise residents have great conflict emotions and are difficult to relieve for a moment. However, the elevator is abandoned only by the objection of the low-rise residents, so that most of the high-rise residents are inconvenient to go out, and the safety of the old and children is caused, which is undoubtedly unhappy.
