The cone crusher mainly comprises a frame, a movable cone, a fixed cone, an eccentric shaft sleeve and the like, wherein the transmission device drives the eccentric sleeve to rotate, the movable cone rotates and swings under the urging of the eccentric shaft sleeve, a section of the movable cone close to the fixed cone becomes a crushing cavity, and materials are crushed by multiple extrusion and impact of the movable cone and the fixed cone. The cone crusher needs to control the idle rotation speed of the movable cone when the idle crusher runs, but the rotation speed of the movable cone of the existing cone crusher when the idle crusher runs generally reaches 200 revolutions per minute, so that the related parts are seriously abraded, parts can be directly burnt out when the parts are serious, and the service life of the cone crusher is influenced.
Disclosure of Invention
The invention provides an anti-rotation device of a cone crusher, which aims to solve the problem that the rotation speed of a movable cone of the existing cone crusher is too high when the existing cone crusher operates in a non-operating state.
The technical scheme adopted by the invention for solving the technical problems is as follows: an anti-rotation device of a cone crusher is used for connecting a main shaft and a movable cone of the cone crusher, and comprises a spherical tile connected with the main shaft and a spherical bearing connected with the movable cone, wherein a convex spherical surface at the bottom side of the spherical bearing is pressed on a concave spherical surface at the top side of the spherical tile, a plurality of vertically arranged blind holes are arranged on the concave spherical surface at the top side of the spherical tile at intervals, a spring is arranged at the bottom end of each blind hole, a damping block is also inserted in each blind hole, the bottom end of each damping block is pressed on the spring, the outer diameter of each damping block is matched with the diameter of each blind hole, so that each damping block can move in each blind hole along the vertical direction, the shape of the top end of each damping block is matched with the concave spherical surface at the top side of the spherical tile, the spherical bearing presses the damping blocks into the blind holes, and enables the top ends of the damping blocks and the concave spherical surfaces at the top side of the spherical tile to be positioned on the same spherical surface which is attached with the convex spherical surface at the bottom side of the spherical bearing, the friction coefficient at the top end of the damping block is larger than that of the concave spherical surface on the top side of the spherical tile, and the friction coefficient at the top end of the damping block and the elastic force of the spring meet the requirement that the autorotation of the spherical bearing can be limited through the matching of the plurality of damping blocks.
Preferably, the cylindrical boss at the top of the spherical bearing is connected with the movable cone body through interference fit, and a plurality of positioning pins are inserted between the spherical bearing and the movable cone body.
Preferably, 6 to 10 damping blocks are inserted into the concave spherical surface on the top side of the spherical tile, and the damping blocks are uniformly distributed at intervals along the circumferential direction of the spherical tile.
Preferably, when the spring is in a natural extension state, the top end of the damping block extends 8-10mm from the concave spherical surface on the top side of the spherical tile.
According to the technical scheme, the invention has the beneficial effects that:
according to the invention, the top ends of the damping blocks are pushed to the spherical surface of the spherical bearing through the springs, and the friction coefficient of the top ends of the damping blocks is also larger than that of the top side of the spherical tile, so that friction force can be generated between the top ends of the damping blocks and the spherical surface at the bottom side of the spherical bearing, and the spherical bearing is limited in autorotation in a matching manner.
