Passenger elevator with external lift car

Abstract

The invention discloses a passenger elevator with an external lift car. The passenger elevator comprises a supporting pipe located right ahead of a balcony; vertical guide tracks are arranged in the supporting pipe and provided with an ascending-descending sliding trolley which ascends or descends along the vertical guiding tracks; a traction motor is arranged on the inner top of the supporting pipe and connected with a traction sheave; a traction rope is wound on the traction sheave; one end of the traction rope is connected with the ascending-descending sliding trolley, and the other end ofthe traction rope is connected with a counter weight; the lift car is arranged between the supporting pipe and the balcony; and the ascending-descending sliding trolley is connected with supporting pieces which extend from the interior of the supporting pipe to the outside of the supporting pipe to be connected with and fixed to the lift car. The balcony of each floor is provided with an elevatordoor corresponding to the lift car. The passenger elevator with the external lift car is simple in structure, and the problems existing when elevators are additionally mounted on old buildings can beeffectively solved.

Description

technical field [0001] The invention belongs to the field of elevators, in particular to a passenger elevator with an external car. Background technique [0002] In civil construction projects, vertical elevators are elevators in which the car is in the well and is directly drawn. Some indoor elevator wells are open, but the car is still directly drawn. [0003] For the vertical elevator installed in the old residential building, the car is also in the shaft, but the shaft structure has various types, such as concrete structure and steel structure. Although the installation of this kind of elevator in the old building meets the basic functions of going up and down the stairs, it also causes the following negative effects: [0004] 1. The length and width of the outside of the elevator shaft is generally 2.2m-2.5m, which is close to the building construction, which seriously affects the ventilation and lighting of the residence, affects the view outside the window, and reduc...

AI Technical Summary

Problems solved by technology

[0004] 1. The length and width of the outside of the elevator shaft are generally 2.2m-2.5m, which is close to the building construction, which seriously affects the ventilation and lighting of the residence, affects the view outside the window, and reduces the living comfort

[0005] 2. The volume of the elevator shaft is large and the appearance is abrupt. It is difficult to coordinate with the building, which will cause great damage to the facade of the building and affect the overall landscape of the community.

[0006] 3. Due to the structure of many old buildings, the installation of elevators can only be leveled on the middle platform of the stairs, and cannot directly reach the floors, which makes the elevator function discounted

There are even many old buildings that cannot be equipped with existing elevators at all

[0007] Fourth, the foundation of the elevator installed is close to the foundation of the original building, which will disturb the foundation of the old building during construction and increase the difficulty of the construction of the elevator foundation

[0008] 5. Due to the uneven settlement of the elevator shaft and the old building, there are many problems in the connection between the elevator shaft and the old building. If it is not handled properly, it will have an adverse effect on the structural safety of the two.

[0009] Now there are other methods for installing elevators in old buildings, such as the patent "CN90108663.0, improving the method of going up and down stairs by adding elevators outside the wall", but there are many technical difficulties that cannot be overcome in this method, and the operability is not strong

[0010] The above problems are an important reason why many existing old buildings cannot be equipped with elevators, so an innovative elevator model is needed to fill the gap
