Description

Technical Field

[0001] This utility model relates to the field of composite lining plates, specifically a novel composite lining plate. Background Technology

[0002] In the field of industrial equipment, liners are widely used as key wear-resistant components in equipment such as crushers, ball mills, and conveyors in industries such as mining, metallurgy, power, and building materials. Their core function is to protect the main body of the equipment from material impact and wear.

[0003] Application No. 202322615088.5 (Authorization Announcement No. CN221334540U) discloses a novel composite liner plate, which adopts a top groove and a wear-resistant round plate. When installing the liner plate body, the screw can pass through the liner plate body and the base plate, and be fixed on the outside of the base plate by fixing nuts. The operation can be carried out above the liner plate body without obstruction, and the installation and disassembly are more convenient and simple.

[0004] However, when using screws to pass through the connection holes, it is difficult to quickly and accurately align the liner body and the base plate, which is inconvenient during installation and requires time and effort to adjust the correct position of the liner body and the base plate. Utility Model Content

[0005] To overcome the above-mentioned shortcomings, this utility model provides a novel composite liner.

[0006] The technical solution adopted by this utility model is as follows:

[0007] A novel composite liner includes a main board with a base plate at its bottom. The main board has a connecting groove at its top center, and connecting holes at the bottom center of both the main board and the base plate. These connecting holes pass vertically through the main board and the base plate, respectively. The top of the connecting hole on the main board communicates with the bottom of the connecting groove. A bolt is installed on the top of the main board, with its bottom end extending through both connecting holes and out of the base plate's bottom. A nut is threaded onto the outer wall of the bolt's bottom end, with the top of the nut pressing against the base plate's bottom. A threaded groove is formed at the top center of the bolt, and a wear-resistant plate is present on the top of the bolt. A threaded short post is fixedly connected to the bottom of the wear-resistant plate, threaded within the threaded groove. The threaded short post and the threaded groove are threaded together. Both the wear-resistant plate and the connecting groove are circular, with the wear-resistant plate embedded within the connecting groove. Positioning protrusions are provided at the bottom of the main board, arranged in a cross shape. A composite rubber pad is present at the bottom of the main board. A positioning groove, also cross-shaped, is provided at the top of the base plate, and it is adapted to match the positioning protrusions.

[0008] The top of the wear-resistant plate is flush with the top of the main plate, the outer wall of the wear-resistant plate slides in fit with the inner wall of the connecting groove, and a slot is opened on the top of the wear-resistant plate.

[0009] The beneficial effects of this utility model are:

[0010] This invention solves the problem of difficult hole alignment during liner installation by using a cross-shaped positioning protrusion and positioning groove design, which greatly improves assembly efficiency and reduces the difficulty of manual operation.

[0011] The cross-shaped positioning protrusions and positioning grooves provide bidirectional constraints, preventing relative displacement between the motherboard and the substrate under complex working conditions, and facilitating easy, fast and stable positioning of the motherboard and substrate.

[0017] like Figure 1-4 As shown: A novel composite liner includes a main board 1, with a substrate 2 at its bottom; a connecting groove 3 is formed in the center of the top of the main board 1, and connecting holes 4 are formed in the center of the bottom of both the main board 1 and the substrate 2, respectively penetrating the main board 1 and the substrate 2 vertically; the top of the connecting hole 4 on the main board 1 communicates with the bottom of the connecting groove 3; a bolt 5 is provided on the top of the main board 1, the bottom end of the bolt 5 extends through the two connecting holes 4 and out of the bottom of the substrate 2; a nut 6 is threaded onto the outer wall of the bottom end of the bolt 5, the top of the nut 6 abuts against the bottom of the substrate 2, and the top of the bolt 5 is positioned at the center. A threaded groove 7 is provided, and the top of the bolt 5 has a wear-resistant plate 8. The bottom of the wear-resistant plate 8 is fixedly connected to a threaded short post 9, which is threaded in the threaded groove 7. The threaded short post 9 and the threaded groove 7 are threadedly connected. Both the wear-resistant plate 8 and the connecting groove 3 are circular. The wear-resistant plate 8 is embedded in the connecting groove 3. The bottom of the main board 1 is provided with a positioning protrusion 10, which is distributed in a cross shape. The bottom of the main board 1 is composite with a rubber pad 11. The top of the base plate 2 is provided with a positioning groove 12, which is cross-shaped and matches the positioning protrusion 10.

[0018] The top of the wear-resistant plate 8 is flush with the top of the main plate 1. The outer wall of the wear-resistant plate 8 slides in conjunction with the inner wall of the connecting groove 3. A slot 13 is opened on the top of the wear-resistant plate 8.

[0019] Align the cross-shaped positioning protrusion 10 at the bottom of the motherboard 1 with the cross-shaped positioning groove 12 at the top of the substrate 2 to achieve quick and accurate alignment of the motherboard 1 and the substrate 2, ensuring that the connection holes 4 of the two are fully connected, greatly improving assembly efficiency, preventing relative displacement between the motherboard 1 and the substrate 2 under complex working conditions, and improving the overall structural stability.

[0020] Insert the bolt 5 into the connecting groove 3 from the top of the motherboard 1, and pass it through the connecting hole 4 of the motherboard 1 and the substrate 2 in sequence. After the bottom end of the bolt 5 extends to the bottom of the substrate 2, use the nut 6 to thread it onto the bolt 5. Tighten the nut 6 so that its top abuts against the bottom of the substrate 2, thus completing the stable connection between the motherboard 1 and the substrate 2.

[0021] Align the threaded short post 9 at the bottom of the wear-resistant plate 8 with the threaded groove 7 at the top of the bolt 5, and use a tool to rotate the wear-resistant plate 8 through the slot 13 so that the threaded short post 9 is screwed into the threaded groove 7, and finally the top of the wear-resistant plate 8 is flush with the top of the main plate 1.
