Description

Multi-cylinder cone crusher and moving cone anti-reversion device thereof

Technical Field

The utility model relates to the field of mining machinery, in particular to a multi-cylinder cone crusher and a movable cone anti-reversion device thereof.

Background

Cone crushers are widely used in industries such as building stones, metallurgy, chemical industry and the like, and can be divided into 1, single-cylinder cone crushers according to the motion trail difference of crushed materials of the equipment structure principle; 2, a multi-cylinder cone crusher. The multi-cylinder cone crusher has the advantages that the particle type of products produced by the crushing motion track of the multi-cylinder cone crusher is better, and the proportion of fine materials is high, so that the multi-cylinder cone crusher is high-end equipment with wide application range of iron ores and nonferrous metal ores.

A multi-cylinder hydraulic rolling cone crusher is a mining machinery generally used to crush large rock into smaller rock or gravel. During operation, the main shaft of the movable cone set is driven by the eccentric shaft to make eccentric rotation around the center of the cone, however, the interface between the eccentric shaft and the movable cone is lubricated, and no device for limiting the rotation direction of the movable cone assembly is provided. In some cases, reversal of the direction of rotation of the movable cone may cause the bearing element to slip on the adjacent surface. This sliding action may lead to premature wear of the bearing elements or permanent damage of the bushing. According to the prior experience, the phenomenon that the material slips in the crushing cavity is caused by the anticlockwise rotation of the movable cone, so that ore discharging particles are large, the production efficiency is reduced, and the energy waste is large.

The dynamic cone anti-reverse rotation mechanism of the cone crusher disclosed in Chinese patent publication No. CN204448102U comprises a vertical shaft, a brake shaft, a one-way clutch and a universal coupling; a brake shaft hole penetrating through the center of the vertical shaft and a backstop mounting groove communicated with the lower end of the brake shaft hole are formed in the vertical shaft; the one-way clutch is arranged in the backstop mounting groove, the brake shaft is arranged in the brake shaft hole in a penetrating way, and the lower end of the brake shaft is connected with the one-way clutch; the universal coupling comprises a torque disc fixed on the lower end face of the movable cone shaft, a brake disc fixed on the upper end part of the brake shaft, and a floating disc arranged between the torque disc and the brake disc; a lower connecting groove is formed in the lower end face of the floating disc, and an upper connecting groove is formed in the upper end face of the floating disc; the torque disc is arranged in the upper connecting groove of the floating disc in a clearance fit manner, and the brake disc is arranged in the lower connecting groove of the floating disc in a clearance fit manner. The movable cone anti-reverse rotation mechanism is used for limiting the movable cone group to directionally rotate and preventing materials from slipping. In the prior patent, the eccentric sleeve of the cone crusher and the matching mechanism of the movable cone body cannot bear axial force, so that a spherical surface upper thrust plate and a spherical surface lower thrust plate are required to be arranged at the upper end of the fixed vertical shaft to support the movable cone assembly, and further bearing and swinging are realized. When the equipment runs for a long time or is in a biased feeding and iron passing state, the radial force and the axial force applied to the movable cone assembly act on the fixed vertical shaft, so that the matching surface of the fixed vertical shaft and the lower frame is easy to loosen to generate cracks, and even the fixed vertical shaft is broken, and the stable running of the equipment is affected.

Further, since the above solution requires a vertical shaft (fixed shaft) to be provided in the lower frame, the anti-reverse structure of the bottom part requires a universal coupling connected to the upper part through a brake shaft, which has at least the following drawbacks:

the brake shaft is adopted for transmission, so that the structure is complex on one hand, and the torsion strength of the brake shaft is weak on the other hand. In this case, since the brake shaft is limited to the shaft hole of the vertical shaft (fixed shaft) and the follower cone cannot swing, it is necessary to install the universal joint above the vertical shaft (fixed shaft) to support the follower cone. Therefore, the universal coupling is also enabled to slide and also rotate circumferentially in the scheme, so that the universal coupling is easy to damage.

On the basis, the Chinese patent publication No. CN116273276A describes a movable cone assembly, which comprises a base, an eccentric sleeve movably arranged in the base, a main shaft with the lower end part movably arranged in the eccentric sleeve, and a movable cone body fastened on the upper end part of the main shaft; the outer side of the eccentric sleeve is provided with a supporting ring body which is in linkage with the circumference of the eccentric sleeve, and the upper end surface of the supporting ring body is constructed into a continuous inclined plane with gradually changing circumferential height; the lower end face of the support ring body is rotatably supported on the base, and the lower end of the movable cone body is rotatably or slidably supported on the continuous inclined plane of the support ring body. The movable cone assembly simplifies the supporting structure of the movable cone body, optimizes the stress structure, drives the supporting ring body to rotate to realize the swing of the movable cone body in the operation process of the movable cone assembly, and the movable cone body is supported by the base, so that the supporting structure of the movable cone body is more reasonable, and optimizes the stress structure.

Based on the optimization of the supporting structure of the movable cone assembly, the vertical shaft (the fixed shaft) in the original equipment is eliminated, so that the original movable cone anti-reverse rotation mechanism needs to be optimized, and the defects of the existing movable cone anti-reverse rotation mechanism are overcome.
