[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to Chinese application CN202311075563.2 filed with the State Intellectual Property Office of China on August 24, 2023. Technical Field

[0003] The present invention relates to an elevator system. Background Art

[0004] During elevator system installation, a traction hoist, such as a Tirak, is often required. It is typically mounted on the system's roof beam. However, a Tirak machine is typically located a significant distance from the car roof, for example, over 1,400 mm. Therefore, if an operator wishes to stand on the car roof to perform installation work, they may be unable to reach the Tirak machine. Consequently, an additional work platform is often required for the operator to stand while installing the remaining guide rails.

[0005] Therefore, there is a need for an elevator system that can use the car roof as a working platform, eliminating the need for an additional working platform.

[0025] In order to make the purpose, technical solution and advantages of the technical solution of the present disclosure clearer, the technical solution of the embodiment of the present disclosure will be clearly and completely described below in conjunction with the drawings of the specific embodiments of the present disclosure. The same figure marks in the drawings represent the same parts. It should be noted that the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0026] Compared to the embodiments shown in the drawings, feasible embodiments within the scope of protection of the present disclosure may have fewer components, additional components not shown in the drawings, different components, differently arranged components, or differently connected components, etc. In addition, two or more components in the drawings may be implemented in a single component, or a single component shown in the drawings may be implemented as multiple separate components.

[0027] Unless otherwise defined, technical or scientific terms used herein should have the ordinary meaning understood by a person of ordinary skill in the art to which this disclosure pertains. The terms "first," "second," and similar expressions used in the patent specification and claims of this disclosure do not denote any order, quantity, or importance, but are merely used to distinguish different components. When the number of components is not specified, the number of components may be one or more; similarly, terms such as "a," "the," and "said" do not necessarily indicate a quantitative limitation. Terms such as "include" or "comprising" mean that the element or object preceding the term includes the elements or objects listed after the term, and their equivalents, but do not exclude other elements or objects. Terms such as "installed," "disposed," "connected," and "connected" are not limited to physical or mechanical installation, disposition, or connection, but may include electrical installation, disposition, or connection, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative orientations of devices during use or as shown in the accompanying drawings. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0028] Figure 1 shows a perspective view of a portion of an elevator system that has been installed and is ready for use. At this point, the top beam 4 is in a first, final position, and the guide shoe 1 remains fixedly mounted to the column, capable of engaging a guide rail (not shown) in the column 2.

[0029] FIG2 illustrates the installation of an elevator system during which the top beam 4 is moved downward to a second position, with the guide shoes 1 mounted to the columns, enabling engagement with guide rails within the columns. This downward movement of the top beam to the second position reduces the distance between the top beam and the elevator car, thereby reducing the distance between a traction hoist 5, such as a Tirak, and the elevator car, allowing operators to use the car roof as a working platform. Because the guide shoes are fixedly mounted to the columns, rather than the top beam, they can still engage the guide rails when the top beam is moved downward to the second position.

[0030] The first position of the header is higher than a second position, which corresponds to a position during installation of the elevator between the final position of the header and the roof of the elevator car.

[0031] The column 2 includes a first mounting feature 21 and a second mounting feature 22. The first mounting feature 21 corresponds to the first position of the top beam to fix the top beam in the first position, and the second mounting feature 22 corresponds to the second position of the top beam to fix the top beam in the second position. The first mounting feature and the second mounting feature are in the form of holes, as shown in FIG7. FIG7 only schematically illustrates a schematic number of first mounting features and second mounting features. Those skilled in the art will understand that the position and number of the first mounting feature 21 can be selected as needed, as long as the final position of the top beam during use of the elevator system can be met. The position and number of the second mounting features 22 can also be selected as needed, as long as the desired second position of the top beam during installation of the elevator system can be met.

[0032] Figures 3, 4 and 5 show how the guide shoe 1 is mounted to the column 2 via a fastening device 3. The fastening device comprises a first plate 31, which is fixed to the column, for example by bolts, and extends parallel to the column 2, that is, vertically parallel to the elevator shaft. The first plate 31 is flat so as to abut against the side of the column. A second plate 32 of the fastening device 3 extends obliquely from the first plate 31, preferably vertically, and the guide shoe 1 is fixedly mounted to the second plate 32.

[0033] The second plate 32 includes one or more holes 33, and the guide shoe 1 is fixedly mounted to the second plate 32 by inserting a bolt into each hole. Preferably, the hole is an elongated hole, and the shape of the elongated hole is designed to extend perpendicularly to the extension direction of the second plate 32, so that the position of the guide shoe can be adjusted in a direction perpendicular to the extension direction of the second plate when the guide shoe is installed.

[0034] In the accompanying drawings, the guide shoe 1 includes a mounting plate 11, which also includes one or more elongated holes 12. The elongated holes in the mounting plate 11 extend perpendicularly to the elongated holes in the second plate. Bolts pass through the elongated holes in both the mounting plate and the second plate, thereby attaching the guide shoe to the second plate. This allows the position of the guide shoe to be adjusted in two directions. However, those skilled in the art will appreciate that the type of guide shoe 1 is not important for this application and that the guide shoe may be any suitable type of guide shoe as long as it is attachable to the second plate.

[0035] The fastening device further includes an inclined plate 34 connected between the first plate 31 and the second plate 32 , which can act as a reinforcing rib.

[0036] With the elevator system of the present application, the position of the top beam can be lowered during the installation of the elevator system, and the top of the elevator car can be used as a working platform, eliminating the need for an additional working platform. At the same time, the guide shoes are installed on the columns instead of the top beam, which still ensures that the guide shoes are engaged with the guide rails without hindering the function of the guide shoes.

[0037] Although the present invention has been described in the specification and illustrated in the drawings with reference to various embodiments, those skilled in the art will understand that the above embodiments are merely preferred implementation methods, and certain technical features in the embodiments may not be necessary for solving specific technical problems, so that these technical features may be absent or omitted without affecting the solution of the technical problems or the formation of technical solutions; moreover, the features, elements and / or functions of one embodiment may be appropriately combined, coupled or coordinated with the features, elements and / or functions of one or more other embodiments, unless the combination, coupling or coordination is obviously not feasible.
