Description

TECHNICAL AREA

[0001] The present application relates to a guide rail for a guide shoe of an elevator and an elevator. STATE OF THE ART

[0002] The guide shoe and guide rail of the elevator are very important components of the passenger transport system and work together to ensure the safe and smooth operation of the elevator.

[0003] The guide rail consists of a pair of parallel rails between the elevator car and the guide rail frame. Its main function is to support and guide the car in its vertical movement while also absorbing the car's vertical load. The guide rails are typically made of steel and possess high strength and wear resistance. The guide shoe is a metal structure attached to the underside of the elevator car. It controls the car's vertical movement and counteracts the weight of the car and passengers by making contact with the guide rail (sliding or rolling contact). The guide shoe is usually made of steel or another high-strength metal and is designed to ensure close contact with the guide rail and provide good sliding properties to reduce friction.

[0004] In short, the guide rail is a very important part of the elevator system, which can ensure the safe, smooth and reliable operation of the elevator.

[0005] In state-of-the-art designs, guide rails are typically T-shaped and mounted on the shaft side walls. Their function is to guide and absorb the impact forces when the cabin and elevator brake. However, the mass of such a T-shaped guide rail is relatively large, which hinders installation and simultaneously increases the cost. ILLUSTRATION OF THE USE SAMPLE

[0006] To overcome the aforementioned problems, the present application provides a guide rail suitable for a guide shoe of an elevator, which extends vertically and has a constant cross-section along its length, comprising:

[0007] A guide section adapted to the guide shoe of the elevator car;

[0008] A support section comprising a first support leg and a second support leg, a first support foot and a second support foot, wherein the first support leg and the second support leg are arranged in cross-section with respect to the central axis of the guide section on both sides thereof, the first support leg extending obliquely to the central axis, the first support foot extending from the first support leg away from the central axis, the second support leg extending obliquely to the central axis, and the second support foot extending from the second support leg away from the central axis to form a cavity within the support section.

[0009] Advantageously, the guide section is directly connected to the support section, so that the first support leg and the second support leg extend away from the guide section.

[0010] Advantageously, the height of the section of the cavity adjacent to the guide section along the central axis is greater than the height of the guide section along the central axis.

[0011] Advantageously, the first support leg and the second support leg are arranged symmetrically to the central axis.

[0012] Advantageously, the first support leg and the second support leg lie in the same plane and run perpendicular to the central axis.

[0013] Advantageously, the first support foot and the second support foot have mounting holes for attaching the guide rail to the elevator shaft.

[0014] Advantageously, the first support leg and the second support leg are designed to pivot relative to the guide section in order to be able to change the inclination angle of the first and second support legs relative to the central axis.

[0015] Advantageously, a connecting section is also provided between the guide section and the support section, which extends along the central axis.

[0016] Advantageously, the thickness of the connecting section measured perpendicular to the central axis is smaller than the thickness of the guide section measured perpendicular to the central axis.

[0017] Advantageously, the heights of the first and second support legs, measured in a direction parallel to the central axis, are variable.

[0018] Advantageously, the section of the cavity adjacent to the guide section is shaped like a circular arc.

[0019] The subject of the present application is also a lift which has a guide rail as described above. DESCRIPTION OF THE DRAWINGS

[0024] The Fig. 1 and Fig. Figure 4 shows a schematic sectional view and a schematic perspective of a guide rail according to the present application. The guide rail is designed to interact with a guide shoe to guide the movement of the cabin. The guide rail runs vertically and has a constant section perpendicular to the vertical direction, as shown in Fig. Figure 1 shows the guide rail 1. The guide rail 1 has a guide section 11 onto which a guide shoe can fit. The support section 12 comprises a first support leg 121 and a second support leg 122, a first support foot 123, and a second support foot 124. In cross-section, a first support leg 121 and a second support leg 122 are provided on both sides of the guide section 11 with respect to the central axis V of the guide section. The first support leg 121 extends obliquely to the central axis towards the first support foot 123, and the second support leg 122 extends obliquely to the central axis towards the second support foot 124, so that a cavity S is formed within the guide section. The first support foot extends from the first support leg away from the central axis, and the second support foot extends from the second support leg away from the central axis. The portion of the cavity adjoining the guide section is arc-shaped.

[0025] By improving the guide rail by transforming the original plate-shaped T-guide rail into a guide rail with a cavity S, not only is the support strength improved, but material savings are also achieved and the overall weight of the rail is reduced compared to existing T-guide rails.

[0026] As in Fig. As shown in Figure 1, the guide section 11 is directly connected to the support section 12, such that a first support leg 121 and a second support leg 122 extend away from the guide section 11. The height H1 of the section of the cavity S adjacent to the guide section along the central axis is greater than the height H2 of the guide section 11 along the central axis.

[0027] The first support leg 121 and the second support leg 122 are arranged symmetrically to the central axis on both sides of the guide section 11, resulting in identical inclination angles for the first support leg 121 and the second support leg 122. However, it is conceivable that the inclination angles of the first support leg 121 and the second support leg 122 could be different. Furthermore, the first and second support legs can also be pivotable relative to the guide section to allow for individual adjustment of the inclination angle.

[0028] In particular, the angle of inclination of the first support leg 121 and of the second support leg 122 is 45 degrees, which allows for a better support effect.

[0029] The first support leg 121 and the second support leg 122 lie in the same plane and run perpendicular to the central axis.

[0030] The first support foot 121 and the second support foot 122 have fastening holes (not shown) for fastening a guide rail to the elevator shaft, in which this elevator rail is fastened by means of fastening elements.

[0031] As from the Fig. 2 and Fig. 3, Fig. 5 and Fig. As can be seen in Figure 6, the guide rail 1 further comprises a connecting section 13, which is arranged between the guide section 11 and the support section 12 and extends along the central axis. A first support leg 121 and a second support leg 122 extend from the connecting section 13 to a first support foot 123 and a second support foot 124.

[0032] The thickness T1 of the connecting section 13, measured perpendicular to the central axis, is smaller than the thickness T2 of the aforementioned guide section 11, measured perpendicular to the central axis.

[0033] The height H of the first support leg 123 and the second support leg 124, measured in a direction parallel to the central axis, is variable.

[0034] The difference between Fig. 2 and Fig. 3 consists solely in the fact that in Fig. 2 the length of the guide section 11 along the central axis is smaller than the length of the connecting section 13 along the central axis whereas in Fig. 3 the length of the guide section 11 along the central axis is greater than the length of the connecting section 13 along the central axis.

[0035] To improve support and save material, the height of the arc-shaped section of the cavity S formed in the guide rail to the floor is greater than the thickness H of the first or second support foot.

[0036] The guide rail according to the present disclosure is improved by forming a cavity in the guide rail by means of two inclined support legs in the support section of the original T-guide rail, thereby improving the support strength and reducing the overall material consumption compared to the existing T-guide rail, thus reducing the cost of the elevator rail.

[0037] Although the utility model is described in the description and illustrated in the drawings by reference to various embodiments, the person skilled in the art can understand that the above embodiments are only preferred embodiments and that certain technical features in the embodiments may not be necessary to solve certain technical problems, so that these technical features may be omitted or left out without affecting the solution to the technical problem or the formation of the technical solution; furthermore, the features, elements and / or functions of one embodiment may be combined or interacted with the features, elements and / or functions of one or more other embodiments accordingly, unless the combination or interaction is obviously not feasible.
