Description

Technical Field

[0001] The present application relates to a guide rail suitable for a guide shoe of an elevator and an elevator. Background Art

[0002] An elevator's guide shoes and guide rails are very important components of the passenger conveying system, working together to ensure the safe and smooth operation of the elevator.

[0003] The guide rails are a pair of parallel tracks between the elevator car and the guide rail frame. Their primary function is to support and guide the car in its vertical direction of motion while also absorbing the car's vertical loads. Guide rails are typically made of steel, offering high strength and wear resistance. The guide shoe is a metal component fixed to the bottom of the elevator car that controls the car's vertical motion and offsets the weight of the car and passengers by contacting the guide rails (sliding or rolling contact). The guide shoe is typically made of steel or other high-strength metals and is designed to ensure close contact with the guide rails 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 installed on the sidewalls of the hoistway. They provide guidance and withstand the impact of the car and elevator braking. However, these T-shaped guide rails are heavy, making them difficult to install and increasing their cost. Utility Model Content

[0030] Figure 1 and Figure 4 The cross-sectional schematic diagram and the three-dimensional schematic diagram of the guide rail according to the present application are respectively shown. The guide rail is suitable for cooperating with the guide shoe to guide the movement of the car. The guide rail extends vertically and has a constant cross section perpendicular to the vertical direction, such as Figure 1As shown. The guide rail 1 includes a guide portion 11, and the guide shoe is suitable for fitting on the guide portion. The support portion 12 includes a first support leg 121 and a second support leg 122, a first support foot 123 and a second support foot 124. In a constant cross-section, the first support leg 121 and the second support leg 122 are arranged on both sides of the guide portion 11 relative to the central axis V of the guide portion. The first support leg 121 extends obliquely to the first support foot 123 relative to the central axis, and the second support leg 122 extends obliquely to the second support foot 124 relative to the central axis, so that a cavity S is formed in the support portion. 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 adjacent to the guide portion is arc-shaped.

[0031] By improving the guide rail, the original plate-shaped T-shaped guide rail is improved into a guide rail with a cavity S, which not only improves the supporting strength, but also saves more materials and reduces the overall weight compared to the existing T-shaped guide rail bottom.

[0032] like Figure 1 As shown, the guide portion 11 is directly connected to the support portion 12, so that the first support leg 121 and the second support leg 122 extend from the guide portion 11. The height H1 of the portion of the cavity S adjacent to the guide portion along the central axis is greater than the height H2 of the guide portion along the central axis.

[0033] The first support leg 121 and the second support leg 122 are symmetrically arranged on either side of the guide portion 11 relative to the central axis, which allows the first support leg 121 and the second support leg 122 to have the same inclination angle. However, it is conceivable that the first support leg 121 and the second support leg 122 can have different inclination angles. Furthermore, the first support leg and the second support leg can be configured to pivot relative to the guide portion to independently change their inclination angles.

[0034] In particular, the inclination angle of the first supporting leg 121 and the second supporting leg 122 is 45 degrees, thereby achieving a better supporting effect.

[0035] The first supporting leg 121 and the second supporting leg 122 are located on the same plane and extend perpendicular to the central axis.

[0036] The first supporting leg 121 and the second supporting leg 122 have fixing holes (not shown) for fixing the guide rail to the elevator hoistway, and the elevator guide rail is fixed in the elevator hoistway by fasteners.

[0037] like Figure 2 and Figure 3 、 Figure 5 and Figure 6As shown, the guide rail 1 further includes a connecting portion 13 disposed between the guide portion 11 and the support portion 12, the connecting portion 13 extending along the central axis. A first support leg 121 and a second support leg 122 extend from the connecting portion 13 to a first support foot 123 and a second support foot 124, respectively.

[0038] The thickness T1 of the connecting portion 13 measured perpendicularly to the central axis is smaller than the thickness T2 of the guiding portion measured perpendicularly to the central axis.

[0039] The height H of the first supporting foot 123 and the second supporting foot 124 measured in a direction parallel to the central axis is variable.

[0040] Figure 2 and Figure 3 The area is only in Figure 2 In the embodiment, the length of the guide portion 11 along the central axis is smaller than the length of the connecting portion 13 along the central axis; Figure 3 In the embodiment, the length of the guide portion 11 along the central axis is greater than the length of the connecting portion 13 along the central axis.

[0041] In order to improve the supporting effect and save materials, the height from the arc-shaped portion of the cavity S formed in the guide rail to the bottom is greater than the height H of the first supporting foot or the second supporting foot.

[0042] According to the guide rail disclosed in the present invention, the original T-shaped guide rail is improved, and a cavity is formed in the guide rail through two inclined support legs at the support part. On the one hand, the supporting strength is improved, and on the other hand, the overall quality is reduced compared with the existing T-shaped guide rail, thereby reducing the cost of the elevator guide rail.

[0043] 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.
