Description

Technical Field

[0001] The utility model relates to the technical field of elevator accessories and equipment, in particular to an elevator counterweight. Background Art

[0002] Elevator cement counterweights (also known as counterweights, balance blocks, etc.) are mainly used in elevator counterweight systems. The traditional method is to pour counterweight concrete materials into the iron box and solidify them. The iron box is generally made of galvanized iron sheets and formed through stamping, bending, welding and other processes. The cost of the parts is high. The high temperature generated during welding destroys the galvanized layer of the solder joints, and the iron box at the welding point is prone to rust and damage. In order to prevent rust, it is generally painted or powdered, which affects the environment. When pouring counterweight concrete materials into the iron box, in order to prevent damage to the iron box, it is difficult to carry out automated production, and the production efficiency is low. Utility Model Content

[0003] In order to solve the technical defects mentioned in the above background technology, the purpose of the utility model is to provide an elevator counterweight.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] An elevator counterweight comprises a core body and a flexible outer layer coated on the outer peripheral side of the core body, wherein the outer layer is integrally formed and bonded to the outer side of the core body.

[0006] By adopting the above technical solution, the six sides of the outer layer are fully wrapped around the outer surface of the core, and the overall strength is higher than that of the traditional cement counterweight. The outer layer can be produced automatically, and the counterweight concrete blank of the counterweight can be produced by fully automatic concrete brick making equipment. In addition, the existing automatic spraying, automatic injection molding, and automatic pouring processes are relatively mature. With the addition of conveyors, stackers, manipulators and other equipment, the entire process can be automated, with high production efficiency, better quality and lower cost.

[0007] Furthermore, the outer layer is configured as a polymer material structure, and the production process is more environmentally friendly than the painting and powder spraying process of traditional cement counterweights.

[0008] Furthermore, the outer covering layer is configured as a polyurethane, plastic, nylon or resin structure to save costs.

[0009] Furthermore, the thickness of the outer covering layers are all set to be the same, which improves the spraying efficiency and also improves the stability of the installation.

[0010] Furthermore, the thickness of the outer cladding layer is set to 0.5 mm-2 mm, which effectively controls the cost while ensuring the strength.

[0011] Furthermore, the outer covering layer is formed by injection molding, pouring, spraying or brushing, and the operation is automated, so the efficiency is higher and the quality of the finished product is better.

[0012] In summary, the beneficial effects of the utility model are:

[0013] The utility model has a six-sided outer layer that is fully wrapped around the outer surface of the core, and the overall strength is higher than that of the traditional cement counterweight. The outer layer can be produced automatically, and the counterweight concrete blank of the counterweight can be produced by fully automatic concrete brick making equipment. Moreover, the existing automatic spraying, automatic injection molding, and automatic pouring processes are relatively mature. With the addition of conveyors, stackers, manipulators and other equipment, the entire process can be automated, with high production efficiency, better quality, and lower cost.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0020] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0021] In the description of the utility model, if there is a word description such as "several", it means one or more, and the meaning of "more" is two or more. Greater than, less than, and more than are understood to exclude the number itself, and above, below, and within are understood to include the number itself. If there is a description of the first, second, and third, it is only used to distinguish the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0022] The following is combined with Figure 1-3 , the embodiments of the utility model are further described in detail.

[0023] An elevator counterweight 1, such as Figure 1 , Figure 2 , Figure 3 As shown, it includes a core body 11 and a flexible outer layer 12 wrapped around the outer circumference of the core body 11 . The outer layer 12 is integrally formed and bonded to the outer side of the core body 11 .

[0024] The core 11 is a prefabricated counterweight concrete blank. The outer layer 12 is fully wrapped around the outer surface of the core 11 on six sides, and the overall strength is higher than that of the traditional cement counterweight. The outer layer 12 can be produced automatically, and the counterweight concrete blank of the counterweight block can be produced using fully automatic concrete brick making equipment. Moreover, the existing automatic spraying, automatic injection molding, and automatic pouring processes are relatively mature. With the addition of conveyors, stackers, manipulators and other equipment, the entire process can be automated, with high production efficiency, better quality, and lower cost.

[0025] The outer layer 12 is set to be a polymer material structure, which is more environmentally friendly than the traditional cement counterweight painting and powder spraying process during the production process. Moreover, its cost is low, only about 50% of the cost of the iron box.

[0026] Specifically, the outer layer 12 is set to polyurethane, plastic, nylon or resin structure to save costs. In this embodiment, polyurethane material is preferred. Polyurethane has high tensile strength and ductility, acid and alkali resistance, and excellent anti-aging performance, which can reach more than 30 years.

[0027] The thickness of the outer cladding layer 12 is set to be the same, which improves the spraying efficiency and also improves the stability of the installation.

[0028] The thickness of the outer cladding layer 12 is set to 0.5 mm-2 mm, which effectively controls the cost while ensuring the strength.

[0029] The outer covering layer 12 is overmolded. Specifically, it can be formed by injection molding, pouring, spraying or brushing, preferably injection molding. Automated operation molding is more efficient and the quality of the finished product is better. Specifically, the outer covering layer 12 can be wrapped on the surface of the prefabricated counterweight concrete blank by spraying, injection molding, pouring and other methods through equipment such as a sprayer and a pouring machine to form a high-strength, fully wrapped elevator counterweight block 1.

[0030] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
