Description

Technical Field

[0001] The present application relates to a guide rail assembly suitable for an elevator and the 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] The first supporting leg 121 and the second supporting leg 122 are located on the same plane and extend perpendicular to the central axis.

[0046] 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.

[0047] like Figure 2 and Figure 3 、 Figure 5 and Figure 6 As 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] The present application also provides a guide rail assembly, which includes the aforementioned guide rail and a fish plate connecting two such guide rails together. Figures 7 to 12 To describe such a guide rail assembly, in such a description, the guide rail is Figure 1 The guide rail is used as an example, but it should be understood that it can also be used Figure 2 and Figure 3 guide rails.

[0054] Figure 7 and Figure 10 The guide rail assembly according to the first embodiment of the present application is shown. The fishplate 2 includes a protrusion 21 and a first base plate 22 and a second base plate 23 located on either side of the protrusion. The protrusion includes a first inclined plate 211 and a second inclined plate 212 connected together. The first inclined plate 211 is parallel to the first support leg 121, and the second inclined plate 212 is parallel to the second support leg 122.

[0055] The protrusion 21 is inserted into the cavity of the two guide rails, so that the first inclined plate 211 fits the first support leg 121 in the cavity, the second inclined plate 212 fits the second support leg 122 in the cavity, the first base plate 22 fits the first support foot under the first support foot 123 and is fixed together (for example, via screws), and the second base plate 23 fits the second support foot under the second support foot 124 and is fixed together.

[0056] Figure 8 and Figure 11 The guide rail assembly according to the second embodiment of the present application is shown. Figure 7and 10 The fishplate 2 also includes a first reinforcing plate 24 extending at an angle from the free end of the first base plate 22 and a second reinforcing plate 25 extending at an angle from the free end of the second base plate 23. The first and second reinforcing plates extend from the first and second base plates, respectively, toward the guide rail. Advantageously, the first and second reinforcing plates extend parallel to, for example, perpendicularly from, the first and second base plates, respectively.

[0057] Figure 9 and Figure 12 A guide rail assembly according to a third embodiment of the present application is shown. This third embodiment differs from the guide rail assembly of the second embodiment in that one of the first and second reinforcing plates 24 and 25 extends toward the guide rail, while the other extends away from the guide rail. In other words, the first and second reinforcing plates extend in opposite directions. Advantageously, the first and second reinforcing plates 24 and 25 include main bodies that are parallel to each other and extend perpendicularly relative to the first and second base plates, respectively.

[0058] In particular, the top of the protruding portion of the fish plate 2 is arc-shaped, such as Figure 7 As shown, it can be a straight line, such as Figure 8 shown.

[0059] 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.
