Description

Technical Field

[0001] This utility model relates to the technical field of single-cylinder cone crushers, and in particular to a liner positioning structure for a single-cylinder cone crusher. Background Technology

[0002] The single-cylinder cone crusher is a high-efficiency crushing equipment incorporating advanced design concepts. It features high efficiency, large production capacity, high-quality aggregates, and ease of maintenance. It is widely used in medium, fine, and ultrafine crushing operations in industries such as metal and non-metal mining, cement, sand and gravel, and metallurgy, and is particularly suitable for hard rock crushing. The liner of the single-cylinder cone crusher is a protective component installed inside the machine, primarily functioning to reduce friction and wear, and extend the machine's service life. Liners are typically made of highly wear-resistant, high-compression-strength, and highly elastic materials, commonly including wear-resistant cast steel, polyurethane elastomers, and copper alloys.

[0003] Currently, most single-cylinder cone crusher liners on the market are prone to wear and tear after prolonged use, requiring replacement. However, replacing single-cylinder cone crusher liners is inconvenient for operators to install and disassemble. Furthermore, existing single-cylinder cone crusher liners have low wear resistance and durability, thus affecting their service life. Utility Model Content

[0019] By adopting the above technical solution, the first hinge rod is hinged to the side wall of the rectangular compartment and the side wall of the sliding sleeve respectively, so that the hydraulic cylinder body is raised and lowered to drive the first hinge rod to rotate.

[0020] As a preferred embodiment of the liner positioning structure of a single-cylinder cone crusher according to the present invention, the cone liner body includes a wear-resistant layer, a first reinforcing layer is provided at the bottom end of the wear-resistant layer, and reinforcing blocks are installed in a horizontal arrangement inside the first reinforcing layer; a second reinforcing layer is provided at the bottom end of the first reinforcing layer, and reinforcing plates are installed in a horizontal arrangement inside the second reinforcing layer.

[0021] By adopting the above technical solution, the reinforcing block is made of hard alloy plate and the reinforcing plate is made of chromium alloy plate, thereby improving the wear resistance and firmness of the conical liner body.

[0022] The liner positioning structure of this utility model for a single-cylinder cone crusher has the following beneficial effects:

[0023] This invention firstly raises and lowers the lifting plate by activating the hydraulic cylinder body. The second hinge rod is hinged to the side wall of the sliding rod and the sliding sleeve, respectively. The first hinge rod is hinged to the inner wall of the rectangular compartment and the side wall of the sliding sleeve, respectively. The raising and lowering of the lifting plate causes the first and second hinge rods to rotate, which facilitates the sliding rod to slide inside the third through hole.

[0039] Combination Figure 1 and Figure 2In the embodiments of this utility model, the outer wall of the conical base plate 2 is equipped with mounting rings 201, and the mounting rings 201 are semi-circular arc-shaped. Through the design of the mounting rings 201, and through the fact that there are multiple sets of mounting rings 201 with the same structure, the assembly effect between the conical base plate 2 and the conical liner plate body 4 is better.

[0040] Combination Figure 2 and Figure 3 In this embodiment of the utility model, the bottom end of the mounting sleeve 5 is provided with a mounting groove 501, and the side walls at both ends of the mounting groove 501 are provided with limiting grooves 502. The inner wall of the mounting groove 501 is provided with a sealing gasket 503. The limiting groove 502 and the sliding rod 606 are engaged with each other, so that the sliding rod 606 is not engaged with the limiting groove 502, thereby facilitating the operator to install and disassemble the conical liner body 4.

[0041] Combination Figure 3 and Figure 5 In an embodiment of this utility model, the installation and disassembly assembly 6 includes a rectangular compartment 601, which is located inside the fixed column 3. A hydraulic cylinder body 602 is installed at the middle position of the bottom end of the rectangular compartment 601, and a lifting plate 603 is installed at the top of the hydraulic cylinder body 602. The outer wall of the lifting plate 603 is fitted with a sliding sleeve 604, and the sliding sleeve 604 has a second through hole 6041 inside. The second through hole 6041 cooperates with the lifting plate 603. The side walls at both ends of the rectangular compartment 601 have first through holes 6011.
