The present application relates to the field of elevator. More specifically, the present application relates to a support column arrangement scheme for an elevator system.
As a tool to facilitate passengers' walking between floors or shorten passengers' walking distance, passenger transportation devices are very common in daily life. As an example, the most commonly seen ones are escalators and elevators usually used between the floors of commercial buildings, and moving walkways usually used in large airports.
For an elevator system, it usually needs to set up a dedicated hoistway to install various components, including: a car running in the hoistway and a counterweight that achieves force balance with the car. In addition, considering that the elevator car should run between floors in the desired directions, the hoistway that houses the elevator car to run is usually enclosed by walls integrally formed with the building, and guide rails are usually set on the walls to guide the operation of the elevator car. Therefore, the car arrangement of the elevator system is usually determined when the building is built. In addition, for a current sightseeing elevator, since it needs to partially lean against the building walls, it can only provide sightseeing with a partial view angle.
The present application provides a truss assembly to at least partially reduce the requirements on the buildings for the installation and arrangement of an elevator system. The present application also provides an elevator system to reduce the requirements on the buildings for its installation and arrangement, and to provide a broader angle of view for sightseeing.

In addition to one or more of the above features, or as an alternative, another embodiment further includes: a shield, arranged between the support column and the through hole of the car, and dads the support column.
In addition to one or more of the above features, or as an alternative, in another embodiment, the car has an inner wall disposed close to the support column and enclosed to form the through hole, wherein, one or more elevator operation panels are arranged on the inner wall.
In addition to one or more of the above features, or as an alternative, in another embodiment, the car has a plurality of car doors arranged around it.
In order to achieve at least one objective of the present application, according to another aspect of the present application, a support column assembly is provided for guiding the movement of a car in an elevator system. The support column assembly comprises: a support column, with the bottom end thereof connected to a mounting base, and the top end thereof connected to a traction machine room; and a counterweight, arranged in the support column and reciprocating along the length direction of the support column when being hauled.
In addition to one or more of the above features, or as an alternative, another embodiment further comprises: a counterweight guiding element, fixedly arranged between the support column and the counterweight along the length direction of the support column, and used to guide the reciprocating movement of the counterweight.
In addition to one or more of the above features, or as an alternative, another embodiment further comprises: a counterweight support and a plurality of counterweight sheets, wherein the counterweight support is used to carry and restrain a plurality of mutually stacked counterweight sheets.
In addition to one or more of the above features, or as an alternative, in another embodiment, the support column is configured as a truss.
According to the support column assembly and the elevator system of the present application, by providing the support column assembly as the movement guiding element of the elevator car, since it is no longer dependent on the wall surface in the installation environment, a dedicated elevator hoistway specially set up against the walls in the building for the elevator car is no longer needed. The improved elevator system can be applied to any environment with through holes in the building, so its applicability is greatly improved. It also provides a technical basis for multi-compartment shared elevators on the same floor. In addition, since it supports the car only by the support column disposed inside the car, it also provides technical support for its realization of panoramic sightseeing.
The present application will be described in detail hereinafter by referring to the exemplary embodiments shown in the accompanying drawings. However, it should be understood that the present application can be implemented in many different forms, and should not be construed as being limited to the embodiments set forth herein. These embodiments are provided here for the purpose of making the disclosure of the present application more complete and comprehensive, and fully conveying the concept of the present application to those skilled in the art.
In addition, for any single technical feature described or implied in the embodiments mentioned herein, or any single technical feature displayed or implied in each drawing, the present application still allows any continued arbitrary combination or deletion of these technical features (or the equivalents thereof) without any technical obstacles, thereby obtaining more other embodiments of the present application that may not be directly mentioned herein.
The present application first describes herein an embodiment of an elevator system with reference to
It should be understood that, although guiding the car is specifically implemented by using the truss 110 for support as described herein in conjunction with the drawings, it can also be implemented in other structural forms with sufficient structural strength, rigidity and cost applicability, such as a column formed by thin walls. In this case, it still has more flexibility than the dedicated hoistway walls installed in the building.

In addition, in order to better realize the installation and connection of the traction assembly and the car, the traction wheels 142 of the traction assembly 140 can be evenly arranged above the car 130 in the circumferential direction and connected to the vertical beam support 152 that supports the car 130, thereby achieving stable traction of the car.
In addition, although the elevator system is taken as an example in the foregoing embodiments for explanation, it should be understood that one aspect of the present application aims to use a support column assembly taking a truss as an example to replace the role of the dedicated elevator hoistway walls in conventional buildings. Therefore, for partially mature elevator cars and traction assemblies, the support column assembly conceived in the present application can also be directly provided for assembly. At this time, the support column assembly may include a support column such as a truss 110 and a counterweight 120 arranged in the support column such as the truss 110. The counterweight 120 can reciprocate along the length direction of the truss 110 when being hauled. Under this configuration, when the support column assembly is connected to the car and the traction assembly of a conventional elevator system, the normal functions of the elevator is also realized, thereby further improving the scope of application of the present concept.
The above examples mainly illustrate the truss assembly and the elevator system of the present application. Although only some of the embodiments of the present application are described, those skilled in the art should understand that the present application can, without departing from the spirit and scope of the invention, be implemented in many other forms. Therefore, the illustrated examples and embodiments are to be considered as illustrative but not restrictive, and the present application may cover various modifications or replacements if not departed from the spirit and scope of the present application as defined by the appended claims.
