Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of elevator guide rail systems, in particular to a guidance system using a concave structure guide rail. Background Art
[0002] In recent years, with the continuous development and progress of science and technology, the height of buildings in my country has become higher and higher, and the application of high-speed heavy-duty elevators has become more and more extensive. Among them, the guide rail system plays an important role in the operation quality of high-speed heavy-duty elevators.
[0003] The guide rail system scheme commonly used in elevators on the market is: T-type guide rails and U-type guide shoes are matched. The T-type guide rail corresponds to the convex structure, and the concave guide rail corresponds to the U-type structure, that is, the convex part of the guide rail corresponds to the concave part of the guide shoe. However, in the application of high-speed and heavy-duty elevators, this guide rail system scheme is insufficient in structural strength and the degree of tightness of matching, and cannot meet the requirements of high-speed and heavy-duty elevators in terms of running quality. Especially when there is a certain degree of overload in the high-speed and heavy-duty elevator car, the life of the guide shoe will drop sharply, and the guide rail, due to its relatively thin structure, makes it easy for the elevator to exceed the vibration standard in the X and Y directions. Utility Model Content
[0004] The utility model aims to provide a guidance system using a concave structure guide rail to solve the problems raised in the above background technology.
[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] Preferably, the main structural shape of the guide rail is U-shaped, π-shaped, or quasi-U-shaped, π-shaped, or other deformations based on U-shaped and π-shaped; the corresponding guide shoe is T-shaped, I-shaped, U-shaped, π-shaped, or quasi-T-shaped, I-shaped, U-shaped, π-shaped, or other deformations based on T-shaped, I-shaped, U-shaped, π-shaped.
[0008] Preferably, the guide rail can be directly or indirectly fixed in the elevator shaft through its A, B, C surfaces and E, F surfaces for guiding the elevator car.
[0009] Preferably, the concave structure of the guide rail can have certain changes, and the change can be to increase or reduce the material; it can also be a continuous multiple concave structures in parallel; or a convex or concave structure is added on the basis of a continuous multiple concave structure. At the same time, in order to match the structure of the guide rail, the guide shoe also makes corresponding structural changes. When the inner cavity of the concave structure of the guide rail reduces the material, the guide shoe can also increase the matching structure with the concave structure of the guide shoe for better guidance effect and provide more stable support and guidance; when the guide rail is a continuous multiple concave structure, the main body of the guide shoe can also be made into a U-shaped structure to increase the guidance coordination or constraint with the guide rail, so that the elevator runs more smoothly and reliably.
[0010] Preferably, the concave structure of the guide rail can have other deformations to facilitate installation and manufacturing; the guide rail can add one or more convex structures or concave structures on each of the surfaces A, B, C, D, E, F, G, and H. Correspondingly, the guide shoe can also add one or more convex structures or concave structures to increase the contact area or matching area with the guide rail, or to connect the parts of the car.
[0011] Preferably, the cross-sectional shape of the matching portion between the guide rail and the guide shoe may be angled, stepped, curved, or have other deformed structures to obtain good matching performance.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] By adopting a concave guide rail and using it in combination with guide shoes of different structures, especially T-shaped guide shoes or U-shaped guide shoes, the structure of the elevator guide rail system becomes more reasonable and reliable, and the guide rail and guide shoe have a long life, providing technical support for the long life and high-quality operation of high-speed and heavy-load elevators.

[0024] The guide rail 1 can be fixed in the elevator shaft directly or indirectly through its A, B, C surfaces and E, F surfaces for guiding the elevator car.
[0025] like Figure 2 As shown in -b, the concave structure of the guide rail 1 may have certain changes, and the change may be to increase or reduce the material;
[0026] like Figure 2 -d, it can also be a series of multiple concave structures in parallel;
[0027] like Figure 2 -e, or adding a convex or concave structure on the basis of multiple consecutive concave structures.
[0028] At the same time, in order to match the structure of the guide rail 1, the guide shoe 2 also undergoes corresponding structural changes.
[0029] like Figure 2 -b, when the inner cavity of the concave structure of the guide rail 1 reduces the material;
[0030] like Figure 2 As shown in -c, the guide shoe 2 may also be provided with a matching structure with the concave structure of the guide shoe 2 for better guidance effect and more stable support and guidance;
[0031] like Figure 2 -d, when the guide rail 1 is in a continuous plurality of concave structures, the main body of the guide shoe 2 can also be made into a U-shaped structure to increase the guiding coordination or constraint with the guide rail 1, so as to make the elevator run more smoothly and reliably.
