Description

Technical Field

[0001] The utility model belongs to the technical field of elevators, and particularly relates to a novel car top wheel structure for villa elevators. Background Technique

[0002] With the development of society, there are more and more villa buildings, and the demand for villa elevators is also becoming more and more extensive. The domestic villa elevator market is growing, and the production design ability of compactness and high operation effect has also become a benchmark for measuring the brand value of elevator enterprises.

[0003] At present, the following problems generally exist in the car top wheel structure of villa elevators on the market:

[0004] The stability of a single or two rope wheel structures is relatively low, and the load is large, and it is easy to slip, thus generating noise and vibration problems, which affect the riding comfort of passengers. Content of the Utility Model

[0005] In view of the above problems, the utility model proposes and designs a novel car top wheel structure for villa elevators.

[0006] The utility model adopts the following technical scheme:

[0007] A novel car top wheel structure for villa elevators, characterized by comprising an upper beam body, vertical beams, upper beam reinforcing ribs, a rope wheel assembly, a rope wheel fixing plate, a vertical rope retaining plate and an upper protective cover. The upper beam body is fixed on both sides of the upper ends of the vertical beams. The upper beam reinforcing ribs and the upper protective cover are fixed in the middle of the two upper beam bodies. The rope wheel fixing plate and the upper protective cover are fixed on the upper beam body. The rope wheel assembly is placed on the rope wheel fixing plate, and the vertical rope retaining plate is fixed on both sides of the rope wheel assembly.

[0008] Further, the rope wheel assembly includes a wheel shaft, a rope wheel, an axial retaining ring and a bearing. The wheel shaft is placed on the rope wheel fixing plate. The bearing and the axial retaining ring are installed at the stepped shafts on both sides of the wheel shaft. The inner ring of the bearing is in interference fit with the wheel shaft, and the wheel shaft is installed on both sides of the wheel shaft and is in interference fit with the outer ring of the bearing.

[0009] Further, the novel car top wheel structure is characterized in that the number of car top wheels is 4.

[0010] To sum up, due to the adoption of the above technical scheme, the beneficial effects of the utility model are as follows:

[0011] 1. The utility model changes the original single-wheel or double-wheel structure of the car top to a four-wheel structure of the car top. By adopting this car top wheel structure, the space at the top of the hoistway can be utilized more effectively, thereby reducing the height of the top floor of the hoistway.

[0012] 2. The utility model can disperse the load of the elevator car more evenly, reduce the pressure on each rope pulley, and reduce the vibration of the car top pulley, thereby providing higher running stability for the villa elevator. Description of the Drawings

[0019] The present utility model will be further described below in conjunction with the drawings and embodiments.

[0020] It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs.

[0021] In the present utility model, it should also be noted that unless otherwise clearly defined and limited, the terms "set", "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the internal communication of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0022] Such as Figures 1-4As shown in the figure, the present utility model provides a technical solution: a novel car top wheel structure for a villa elevator, which includes an upper beam body 1, vertical beams 2, upper beam reinforcing ribs 3, rope wheel assemblies 4, rope wheel fixing plates 5, vertical rope retaining plates 6 and upper covers 7. The vertical beams 2 and the upper beam reinforcing ribs 3 are connected to the middle of the two upper beam bodies 1 by bolts. The rope wheel fixing plates 5 are connected to the upper beam bodies 1 by bolts. The rope wheel assemblies 4 are placed on the rope wheel fixing plates 5. The vertical rope retaining plates 6 are fixed to both sides of the rope wheel assemblies 4 by bolts. The upper covers 7 are fixed to the upper beam bodies 1 by screws.

[0023] As Figure 5 shown in the figure, the rope wheel assembly 4 includes a wheel shaft 8, a rope wheel 9, a shaft retaining ring 10 and a bearing 11. The wheel shaft 8 is placed on the rope wheel fixing plate 5. The bearing 11 and the shaft retaining ring 10 are installed at the stepped shafts on both sides of the wheel shaft 8. The inner ring of the bearing 11 is in interference fit with the wheel shaft 8. The rope wheel 9 is installed on both sides of the wheel shaft 8 and is in interference fit with the outer ring of the bearing 11.

[0024] The number of the car top wheels is 4.

[0025] Working principle: By arranging 4 car top wheels on the vertical beam body 1, the elevator traction rope drives the car to lift and lower through the rope wheel 9 on the car top. This mechanism uses 4 car top wheels to achieve the purpose of smooth operation of the villa elevator, and at the same time reduces the top floor height of the hoistway and saves space.

[0026] Although the present utility model has been disclosed as above by embodiments, it is not intended to limit the present utility model. Any person skilled in this art can make some changes and modifications without departing from the spirit of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the scope claimed in the claims.
