Description

TECHNICAL AREA

[0001] The application concerns a guide rail arrangement suitable for 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 simultaneously 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 guides 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 the prior art, 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

[0028] 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. This guide rail is designed to interact with a guide shoe to guide the movement of the cabin. This guide rail runs vertically and has a constant section in the horizontal plane, as shown in Figure 4. Fig. 1. This guide rail 1 has a guide section 11 which interacts with a matching guide shoe. A support section 12 of the guide section 11 comprises a first support leg 121 and a second support leg 122, a first support foot 123 and a second support foot 124. In the constant section of the guide rail, with respect to the central axis V, the first support leg 121 and the second support leg 122 are arranged on both sides of the guide section 11, the first support leg 121 extending obliquely to the central axis V and to the first support foot 123, and the second support leg 122 extending obliquely to the central axis V and to the second support foot 124, so that a cavity S is formed within the support section 12. The first support leg 123 extends from the first support leg 121 away from the central axis and the second support leg 124 extends from the second support leg 122 away from the central axis.The section of cavity S adjacent to the guide section 11 is shaped like a circular arc.

[0029] By improving the guide rail from the original plate-shaped T-guide rail to a guide rail with a cavity S, not only is the support strength improved, but material is also saved and the overall weight is reduced compared to existing T-guide rails.

[0030] The first support leg 121 and the second support leg 122 are arranged symmetrically to the central axis V 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 are 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.

[0031] 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.

[0032] The first support leg 121 and the second support leg 122 lie in the same plane and run perpendicular to the central axis V.

[0033] The first support foot 121 and the second support foot 122 have fastening holes (not shown) for fastening the guide rail 1 to the elevator shaft, in which this elevator rail 1 is fastened by means of fastening elements.

[0034] As from the Fig. 2 and Fig. 3, Fig. 5 and Fig. As can be seen in Figure 6, the guide rail 1 can further comprise a connecting section 13, which is arranged between the guide section 11 and the support section 12 and extends along the central axis V. The first support leg 121 and the second support leg 122 extend from the connecting section 13 to the first support foot 123 and the second support foot 124.

[0035] The thickness T1 of the connecting section 13, measured perpendicular to the central axis V, is preferably smaller than the thickness T2 of the said guide section, measured perpendicular to the central axis V.

[0036] The strength H of the first support foot 123 and the second support foot 124, measured in a direction parallel to the central axis, can be varied.

[0037] The difference between the 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 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.

[0038] To improve support and save material, the height of the arc-shaped section of the cavity S formed in the guide rail 1 to the floor is greater than the thickness H of the first or second support foot.

[0039] The guide rail according to the present disclosure is improved by replacing the original T-guide rail with a guide rail having two inclined support legs in the support section, between which a cavity is formed in the guide rail, thereby improving the support strength on the one hand and reducing the material consumption compared to the existing T-guide rail on the other, thus reducing the cost of the elevator rail.

[0040] The present application further relates to a guide rail arrangement comprising the aforementioned guide rails and a fishplate connecting two such guide rails. Such a guide rail arrangement is described below with reference to the Fig. 7 to 12 described, the guide rail being described using the example of the guide rail according to Fig. As explained in section 1, it is understood that the guide rails also comply with the above. Fig. 2 and Fig. 3 can be used.

[0041] The Fig. 7 and Fig. Figure 10 shows a guide rail arrangement according to a first embodiment of the application. The fishplate 2 comprises a projection 21 and a first base plate 22 and a second base plate 23 on both sides of the projection, wherein the projection 21 comprises a first inclined plate 211 and a second inclined plate 212 which are connected to each other, the first inclined plate 211 being parallel to the first support leg 121 and the second inclined plate 212 being parallel to the second support leg 122 of the guide rail 1.

[0042] This projection 21 is inserted into the cavity S of the two guide rails 1 such that the first inclined plate 211 rests against the first support leg 121 inside the cavity S, and the second inclined plate 212 rests against the second support leg 122 inside the cavity S, and the first base plate 22 rests against the underside of the first support foot 123 and is attached to it, for example by screws, and the second base plate 23 rests against the underside of the first support foot 123 and is attached to it, for example by screws.

[0043] The Fig. 8 and Fig. Figure 11 shows a guide rail arrangement according to a second embodiment of the present application. In addition to the features shown in the Fig. 7 and Fig. As shown in Figure 10, the fishplate 2 has a first stiffening plate 24, which extends at an angle from the free end of the first base plate 22, and a second stiffening plate 25, which extends at an angle from the free end of the second base plate 23. The first and second stiffening plates extend from the first and second base plates, respectively, towards the guide rail. Advantageously, the first stiffening plate and the second stiffening plate extend parallel, for example, perpendicularly from the first and second base plates.

[0044] The Fig. 9 and Fig. Figure 12 shows a guide rail arrangement according to a third embodiment of the present application. The guide rail arrangement of this third embodiment differs from the rail arrangement of the second embodiment in that one of the first and second stiffening plates 24 and 25 extends towards the guide rail and the other extends away from the guide rail, i.e., the first and second stiffening plates 24, 25 extend in opposite directions. Advantageously, the first stiffening plate 24 and the second stiffening plate 25 extend parallel to each other and perpendicular to the first and second base plates.

[0045] In particular, the upper surface of the projection of fish plate 2, as shown in Fig. 7 shows that it can be circular arc-shaped. However, it can also be straight, as in Fig. 8 shown.

[0046] 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.
