Description

Technical Field

[0001] The present invention relates to the technical field of single-cylinder cone crushers, and relates to a single-cylinder cone crusher that is convenient for disassembly. Background Art

[0002] With the country increasing investment in infrastructure construction, metallurgical mines, hydropower, nuclear power, highways, railways, docks, urban construction, waste recycling, etc. will be greatly developed, and the national demand for fixed crushing systems has increased. Among them, single-cylinder hydraulic cone crushers can be widely used in various industrial fields such as ferrous, non-ferrous, and non-metallic mines and sand and gravel. Its characteristics such as large crushing force, high production efficiency, laminating crushing, uniform finished particle shape, low consumption of consumable parts, and low operating cost make single-cylinder hydraulic cone crushers play an indispensable and important role in the crushing industry. Its principle is that a pair of meshing gears drives an eccentric mechanism to drive the moving cone assembly to perform eccentric swinging motion, thereby squeezing and crushing the materials in the crushing cavity.

[0003] When the cone crusher is working normally, due to the continuous friction contact between the moving and stationary cone liners and the materials, the moving and stationary cone liners are vulnerable and consumable parts. Under normal use, the moving and stationary cone liners need to be replaced every half month. The single-cylinder cone crusher can be disassembled and maintained from the upper part. However, since the upper and lower frame assemblies are in interference fit through the conical surface, in order to ensure the normal and continuous operation of the equipment, and after multiple disassembly and assembly of replacing the liners, the conical surface mating part of the upper and lower frames is prone to deformation, so it is difficult to disassemble the upper and lower frames. Summary of the Invention

[0004] To solve the problem of difficult disassembly of the upper and lower frames, the present invention discloses a single-cylinder cone crusher that is convenient for disassembly. By designing an interference ring, the original direct interference fit between the upper and lower frames through the conical surface is changed to connecting the interference ring and the upper frame through bolts. Among them, the interference ring and the lower frame are in interference fit through the conical surface, and a copper alloy gasket is added for auxiliary fit. During the disassembly process, directly removing the bolts can directly lift out the upper frame, so that the upper frame assembly can be quickly disassembled and lifted away from the main equipment, thereby replacing the liners and performing maintenance on the single-cylinder cone crusher.

[0005] To achieve the above object, the technical solution adopted by the present invention is: a single-cylinder cone crusher that is convenient for disassembly, including an upper frame, a fixed cone liner, a lower frame assembly, an interference ring, and a tensioning ring; an interference ring is arranged below the upper frame, and a tensioning ring is arranged below the interference ring. The interference ring and the tensioning ring are locked below the upper frame through a locking mechanism. The fixed cone liner is held by the tensioning ring and tightened and fixed along the inner conical surface of the interference ring; the inner conical surface of the lower frame assembly is in interference fit with the outer conical surface of the interference ring.

[0006] More specifically, the locking mechanism is a bolt and a nut.

[0007] More specifically, a spring is sleeved inside the locking mechanism.

[0008] More specifically, a gasket is installed on the inner conical surface of the lower frame assembly, and the outer conical surface of the interference ring is in interference fit with the gasket.

[0009] More specifically, the gasket is a copper alloy gasket.

[0010] More specifically, the upper frame is an annular housing part, and bolt holes are machined in its lower flange for fastening and fitting the upper and lower frames through bolt connection. Its lower end face is a plane, and an annular mating groove is machined in the plane for radial positioning of the interference ring.

[0011] More specifically, the depth of the annular mating groove on the lower end face of the upper frame is higher than the height of the part of the interference ring that mates with it.

[0012] More specifically, the interference ring is circular, and several interference ring holes are evenly machined on its surface, and all are through holes. A positioning step is provided on the interference ring for positioning the upper frame.

[0013] More specifically, several interference ring threaded holes are evenly machined on the lower end face of the interference ring. The inner ring surface of the interference ring is a tightening surface for lining plate fitting, which is conical and has the same inclination angle as the inclined surface angle of the fixed cone lining plate.

[0014] More specifically, the tightening ring is circular, and several tightening ring holes are evenly machined on its surface.

[0015] More specifically, an anti-wear step is machined at the lower part of the tightening ring.

[0016] The technical effect of the present invention: The interference ring and the tightening ring are fixed together by bolts. At the same time, the fixed interference ring and tightening ring are fixed on the upper frame by bolts and disc springs. At the same time, the fixed cone lining plate is held by the tightening ring and tightened and fixed along the inner conical surface of the interference ring. The copper alloy gasket is welded to the upper inner conical surface of the lower frame to form an integral body. Then, the upper frame assembly is in interference fit with the inner conical surface of the copper alloy gasket in the lower frame assembly through the outer conical surface of the interference ring until the flange surfaces of the upper and lower frames are completely flat, and finally they are connected and fastened by bolts, thus realizing the fixation of the fixed cone lining plate and the interference fit connection of the upper and lower frame assemblies.

[0017] By designing the interference ring in the present invention, the original direct conical surface fit between the upper and lower frames is changed to connecting the interference ring and the upper frame together by bolts. Among them, the interference ring and the lower frame are in conical surface fit, and a copper alloy gasket is added for auxiliary fit. During the disassembly process, the upper frame can be directly lifted out by directly disassembling the bolts, so that the upper frame assembly can be quickly disassembled and lifted off the main equipment, thereby facilitating the replacement of the lining plate and maintenance of the main equipment.

[0028] As Figures 1 - 7As shown, a single-cylinder cone crusher that is easy to disassemble includes an upper frame assembly 1, a main shaft assembly 2, and a lower frame assembly 3. The upper frame assembly 1 includes an upper frame 4 and a fixed cone liner 15, and the lower frame assembly 3 includes a lower frame 5, and also includes a copper alloy liner 9, a bolt II 10, a bolt guide sleeve 12, a disc spring I 13, a disc spring II 17, and a tension ring 18; the tension ring 18, the disc spring II 17, and the interference ring 16 are sequentially sleeved on the bolt II 10, the interference ring 16 and the tension ring The ring 18 is fixed together by bolts III 19, flat washers II 20, and spring washers 21. At the same time, disc springs II 17 are also fixed between the interference ring 16 and the tension ring 18. Then the bolts II 10 pass through the upper frame 4, and the large flat washers 14, disc springs I 13, bolt guide sleeves 12, and nylon nuts 11 are installed on the threaded ends in sequence. The nylon nuts 11 are tightened to lock the interference ring 16 and the tension ring 18 with the upper frame 4. The nylon nuts 11, bolt guide sleeves 12, and disc springs I 13 are installed on the threaded ends in sequence. The shaped spring Ⅰ13 and the large flat washer 14 are sequentially sleeved on the threaded end of the bolt Ⅱ10 from top to bottom. When the nylon nut 11 is tightened, the fixed cone liner 15 is dragged by the tension ring 18 and tightened and fixed along the inner cone surface of the interference ring 16. The copper alloy liner 9 is welded to the upper inner cone surface of the lower frame 5 as a whole. Then, the upper frame assembly 1 is interference-fitted with the inner cone surface of the copper alloy liner 9 in the lower frame assembly 3 through the outer cone surface of the interference ring 16 until the flange surfaces of the upper frame 4 and the lower frame 5 are completely flat. Finally, the upper frame 4 and the lower frame 5 are connected and fastened by bolts Ⅰ6, nuts 7 and flat washers Ⅰ8. During the disassembly of the upper and lower frames, the bolts Ⅰ6 are first removed, and then the nylon nuts 11 are removed. The interference ring 16, the tensioning ring 18 and the fixed cone liner 15 are separated from the upper frame assembly 1 by utilizing the deadweight of the fixed cone liner 15 and the elastic force of the disc spring Ⅱ 17, so that the upper frame assembly 1 can be quickly disassembled and lifted away from the host equipment, so as to replace the liner and maintain the host equipment.

[0029] Among them, the upper frame 4 is an annular shell part, and bolt holes are processed on its lower flange for fastening the upper and lower frames through bolt connection. Its lower end face is a plane, and an annular matching groove 30 is processed in the plane, which serves to radially position the installation interference ring 16.

[0030] The depth of the annular matching notch 30 on the lower end surface of the upper frame 4 is higher than the height of the portion of the interference ring 16 that matches it, so that the interference ring 16 can be installed completely flush with the upper frame 4.

[0031] The interference ring 16 is annular, and has several interference ring holes 22 evenly processed on its surface, and all of them are through holes, which are used to connect the interference ring 16 with the upper frame 4 through bolts II 10. A positioning step 23 is provided on the interference ring 16 for positioning the upper frame 4.

[0032] Among them, several interference ring threaded holes 25 are evenly machined on the lower end face of the interference ring 16. Its function is to connect the interference ring 16 and the tension ring 18 through the bolt III 19. The inner ring surface of the interference ring 16 is the lining plate mating tension surface 24, which is conical, and the inclination angle is the same as that of the fixed cone lining plate inclined surface. Its function is to use the conical surface for mating, and then through the tension force of the bolt II 10, the fixed cone lining plate 15 and the interference ring 16 can be closely mated.

[0033] Among them, the tension ring 18 is circular, and several tension ring holes I 28 and tension ring holes II 29 are evenly machined on its surface, and both are through holes. Its function is to connect the interference ring 16 and the tension ring 18 through the bolt III 19 and connect the interference ring 16, the tension ring 18 and the upper frame 4 through the bolt II 10.

[0034] Among them, an anti-wear step 27 is machined at the lower part of the tension ring 18, and its height requirement is higher than the bolt head height of the connecting bolt II 10 and the connecting bolt III 19. Its function is to prevent the broken materials from wearing the connecting bolt head and causing the tension ring 18 and the interference ring 16 to fall off.

[0035] The above-disclosed is only a preferred embodiment of the present invention. Of course, it cannot be used to limit the scope of the rights of the present invention. Those of ordinary skill in the art can understand all or part of the processes of implementing the above embodiments, and the equivalent changes made according to the claims of the present invention still fall within the scope covered by the invention.
