[0017] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0018] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" and the like are used to indicate positions or locations based on those shown in the accompanying drawings. These terms are intended solely to facilitate the description of this utility model and to simplify the description. They are not intended to indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used solely for descriptive purposes and should not be construed as indicating or implying relative importance.

[0019] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0020] Figure 2 It is a structural diagram of the counterweight block in the utility model; Figure 3 This is a side view of the counterweight block in this utility model. Figures 2 to 3The figure shows a preferred embodiment of a notched mineral powder counterweight for an elevator, comprising a counterweight 1 and a gridded rope stopper plate 2 mounted on the counterweight 1. The gridded rope stopper plate 2 is mounted on the compensating wheel wire rope 3. The figure also includes a reinforcement structure 5. A notch 4 is provided on one side of the counterweight 1, through which the compensating wheel wire rope 3 can pass. The outer wall of the counterweight 1 is wrapped with the reinforcement structure 5. In this embodiment, the notch 4 is provided in the middle of one side of the counterweight 1 to facilitate the passage of the compensating wheel wire rope 3, thus providing a clearing effect and preventing the compensating wheel wire rope 3 from contacting the counterweight 1 and causing friction, which could affect the service life of the compensating wheel wire rope 3.

[0021] Among them, the reinforcement structure 5 is set on the outer wall of the counterweight block 1, and the inner wall of the gap 4 is also provided with the reinforcement structure 5, which can increase the overall strength of the counterweight block 1 and meet the strength requirements.

[0022] Furthermore, as a preferred embodiment, the reinforcement structure 5 includes a reinforcement plate, which is installed on the outer wall of the counterweight 1. The reinforcement plate in this embodiment is made of metal material, specifically stainless steel or iron. There are mainly two types of counterweights 1 in the prior art. One is a counterweight 1 made by mixing cement, sand, stone, water and admixtures in a certain proportion to form a mixture and injecting it into a mold equipped with steel bars. However, this type of counterweight 1 cannot be provided with a gap 4 due to its own strength limitation. If a gap 4 is provided, it will lead to insufficient strength. The other type of counterweight 1 is made entirely of metal material, and the manufacturing cost of this type of counterweight 1 is relatively high. The counterweight 1 in this application is the first type of counterweight 1, and is combined with the setting of the reinforcement structure 5, so that the counterweight 1 still has sufficient strength even after the gap 4 is provided, and can reduce costs without affecting normal use.

[0023] The installation method of the counterweight 1 in this embodiment is the same as that of the counterweight 1 in the prior art, and is not limited here.

[0024] Furthermore, as a preferred embodiment, the reinforcement plate is welded to the outer wall of the counterweight 1. In other embodiments, the reinforcement plate can be riveted to the outer wall of the counterweight 1, or can be installed on the outer wall of the counterweight 1 by a combination of welding and riveting. Riveted posts can be provided on the reinforcement plate, and rivet holes can be provided on the counterweight 1 to cooperate with the riveted posts. After the two are riveted, they can be fixed by welding.

[0025] The above description is only a preferred embodiment of the present invention and does not limit the implementation method and protection scope of the present invention. For those skilled in the art, it should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
