Description

Technical Field

[0001] This utility model relates to the field of elevator technology, specifically to an elevator landing sill and an elevator including the elevator landing sill. Background Technology

[0002] Currently, most elevator landing sills on the market use a structure combining pure aluminum profiles as the main guide material with metal support plates for auxiliary support. For some heavy-duty elevators, cast iron is used as the main guide material. The main disadvantages of this type of sill structure in existing technology are: 1) The aluminum or cast iron main guide material not only serves a guiding function but also a supporting function, resulting in thicker aluminum main guide materials, more material usage, and higher costs; 2) While cast iron main guide materials provide better support, their weight is significant, causing installation inconvenience and increasing operating costs; 3) The existing main guide structure and auxiliary support structure are fixed to the sill bracket as a whole, making replacement difficult during later maintenance. Utility Model Content

[0003] In view of this, in order to overcome the shortcomings of the prior art, the present invention provides an improved elevator landing sill.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] This utility model provides an elevator landing sill, including a sill body, a sill support, and a guide member detachably connected to the sill body.

[0018] Compared with the prior art, the advantages of this utility model are as follows: This utility model provides an elevator landing sill with a detachably connected sill body and guide component. By connecting the bottom of the sill body to the sill support, the guide component can be replaced separately without disassembling the sill body, facilitating the installation and disassembly of the landing sill and improving work efficiency. The structural design of the sill body and guide component, as well as their cooperation method, allows the guide component to only provide horizontal guidance (using thinner and lighter aluminum materials compared to the prior art), while the sill body provides support. This not only increases the overall strength of the landing sill but also effectively saves material costs. Attached Figure Description

The third bottom plate 11 and the fourth bottom plate 12 are both fixedly connected to the sill support 2. The first support plate 15, the second support plate 16, and the fifth side plate 17 are all located between the plane where the third top plate 13 is located and the plane where the third bottom plate 11 is located. In addition, the thickness of the third bottom plate 11, the fourth bottom plate 12, the third top plate 13, the fourth top plate 14, the first support plate 15, the second support plate 16, and the fifth side plate 17 is 0.8 to 3 mm and is greater than the wall thickness of each plate of the guide member 3.

[0031] The first support plate 15, the second support plate 16, and the fifth side plate 17 are all perpendicular to the third bottom plate 11. The inner walls of the third bottom plate 11 and the two first support plates 15 together enclose and form the third through cavity 1a. The third top plate 13 and the fifth side plate 17 form the first bent portion 1b, which is located inside the third through cavity 1a. The fourth top plate 14, the second support plate 16, and one first support plate 15 away from the third top plate 13 together form the second bent portion 1c, which is located outside the third through cavity 1a. Compared with the existing sill body, the arrangement of the first bent portion 1b, the two first support plates 15, and the second support plate 16, through the bending of steel plates, adds more support structures in the vertical direction, which is beneficial to improving the overall support strength of the sill body 1 of this utility model.

[0032] Specifically, such as Figure 1 and Figure 3As shown, when the guide member 3 of this utility model is connected to the sill body 1, the guide member 3 is inserted from one end of the third through cavity 1a of the sill body 1. After the guide member 3 is inserted into place, it is fixed to the sill body 1 with bolts and nuts. After the sill body 1 and the guide member 3 are installed, the third through cavity 1a is used to accommodate the protruding part 3a, the first through cavity 3b is used to accommodate the first bent part 1b, and the second through cavity 3c is used to accommodate the second bent part 1c. The inner wall of the fourth side plate 39 is attached to the outer wall of a first support plate 15 away from the fourth top plate 14 and connected by bolts and nuts. The top surface of the third top plate 13 is attached to the bottom surface of the first top plate 33. The bottom surface of the second top plate 34 is attached to the top surface of the fourth top plate 14 and connected by bolts and nuts.

[0033] Furthermore, to ensure effective cooperation between the guide member 3 and the sill body 1, the height of the fifth side plate 17 is less than the height of the first support plate 15 and the first cavity 3b. The width of the first cavity 3b is greater than the distance between the outer wall of the fifth side plate 17 and the outer wall of the first support plate 15 away from the fourth top plate 14. The height of the third cavity 1a is greater than the height of the protrusion 3a. The width of the second cavity 3c is greater than or equal to the width of the second bend 1c. Additionally, there is a gap between the third side plate 37 and the fifth side plate 17, and a gap between the first side plate 35 and the first support plate 15 away from the third top plate 13. This arrangement aims to provide sufficient space for the guide member 3 and the sill body 1 to undergo minor deformation under stress, thus preventing excessive compression.

[0034] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model.
