Description

Technical Field

[0001] This utility model belongs to the field of wear-resistant plate technology, and in particular relates to a cast wear-resistant liner. Background Technology

[0002] Loaders are common equipment in construction machinery and are widely used in roads, mines and ports. Especially in ports and docks, the frequent operation of loaders when loading and unloading coal and ore can cause significant wear on their buckets, especially at the bottom of the bucket. Therefore, wear-resistant liners are usually added to the buckets to improve their service life.

[0003] Currently, wear-resistant liners in existing technologies are typically one-piece structures. However, due to uneven wear, the lifespan of different parts of the liner is inconsistent. When the wear on the working surface reaches its limit, there is often still a significant amount of residual material on the non-working surfaces and the mounting base. Existing one-piece liners must be completely removed during replacement, which not only wastes materials but also increases spare parts costs. Therefore, there is an urgent need to research a cast wear-resistant liner to solve these problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1:

[0028] Please see Figure 1-6As shown, this utility model is a cast wear-resistant liner, including a base plate 1 and a plurality of liner plates 2 arranged side by side; the edges of two adjacent liner plates 2 abut against each other; the base plate 1 and the plurality of liner plates 2 are all made by casting; a plurality of guide grooves 101 with a T-shaped cross-section are arranged side by side on one surface of the base plate 1, and the two ends of any one guide groove 101 respectively penetrate one opposite side of the base plate 1; a plurality of protrusions 201 with a T-shaped cross-section are integrally formed side by side on one surface of each of the plurality of liner plates 2, and the two ends of any one protrusion 201 respectively extend to one side of the liner plate 2.

In use, the protrusions 201 on the multiple liners 2 are slidably inserted into the multiple guide grooves 101 on the base plate 1. The T-shaped structure between the protrusions 201 and the guide grooves 101 is used to prevent relative movement between the liners 2 and the base plate 1. The base plate 1, the liners 2 and the bucket are then connected together by the first bolt 3, thereby stably connecting the multiple liners 2 to the bucket. When a liner 2 is severely worn, it can be removed and replaced with a new liner 2, which not only effectively avoids material waste but also reduces the cost of use.
