Multicylinder hydraulic roll cone disintegrating machine mantle rotation-preventing mechanism
[technical field]
The present invention relates to mine mechanism, relate in particular to the rotation-preventing mechanism of multicylinder hydraulic roll cone disintegrating machine.
[background technology]
Multicylinder hydraulic roll cone disintegrating machine is a kind of mine mechanism, and the mantle body of existing gyratory crusher does not have Device for preventing rotation, thereby the mantle body in theory can free rotation arbitrarily in crusher chamber.According to existing experience; The mantle body that does not have Device for preventing rotation not only can rotate in crusher chamber in a clockwise direction, also possibly counterclockwise rotate; The phenomenon that the rotation counterclockwise of mantle body can cause material in crusher chamber, to skid; Thereby cause the ore discharge particle big, and production efficiency reduces, and energy waste is big.
[summary of the invention]
The object of the invention solves the problems of the prior art exactly, proposes a kind of multicylinder hydraulic roll cone disintegrating machine mantle rotation-preventing mechanism, can control the mantle body according to certain direction rotation, thereby enhance productivity, and saves the energy.
For realizing above-mentioned purpose; The present invention proposes a kind of multicylinder hydraulic roll cone disintegrating machine mantle rotation-preventing mechanism, comprise brake axle, brake disc, freewheel clutch, cut-out screw, guide ring, universal floating disc, torque plate, said universal floating disc has last working face and following working face; Freewheel clutch has inner ring and outer ring; The last working face of said universal floating disc and torque plate matched in clearance, torque plate is connected with the mantle turning handle, the following working face of universal floating disc and brake axle matched in clearance; One end of brake axle is fixedly connected with brake disc; Brake disc cooperates installation with universal floating disc, and the other end of brake axle is fixedly connected with the inner ring of freewheel clutch, and the outer ring of freewheel clutch is connected with guide ring through cutting off screw.
As preferably, have at least one oil storage tank on the said universal floating disc, guaranteed the sufficient lubrication of device, prolonged service life.
As preferably, said brake axle is provided with key pin, is fixedly connected through key pin between brake disc and the brake axle, also is fixedly connected through key pin between the inner ring of freewheel clutch and the brake axle, and is simple in structure, is connected firmly.
Beneficial effect of the present invention: the present invention has guaranteed mantle by certain direction rotation, prevents that mantle is rotated counterclockwise to cause material skidding in crusher chamber, to occur, has improved production efficiency, has reduced energy waste, has played the effect of energy savings.The present invention is simple in structure, and cost is low, and is easy for installation.
Characteristic of the present invention and advantage will combine accompanying drawing to be elaborated through embodiment.

[specific embodiment]
Like Fig. 1, shown in 2; Multicylinder hydraulic roll cone disintegrating machine mantle rotation-preventing mechanism comprises brake axle 6, brake disc 4, freewheel clutch 7, cuts off screw 8, guide ring 9, universal floating disc 3, torque plate 2, and said universal floating disc 3 has last working face 31 and following working face 32; Freewheel clutch 7 has inner ring and outer ring; The last working face 31 and torque plate 2 matched in clearance of said universal floating disc 3, torque plate 2 is connected with mantle turning handle 1, the following working face 32 and brake axle 6 matched in clearance of universal floating disc 3; One end of brake axle 6 is fixedly connected with brake disc 4; Brake disc 4 cooperates installation with universal floating disc 3, and the other end of brake axle 6 is fixedly connected with the inner ring of freewheel clutch 7, and the outer ring of freewheel clutch 7 is connected with guide ring 9 through cutting off screw 8.Said brake axle 6 is provided with key pin 5, is fixedly connected through key pin 5 between brake disc 4 and the brake axle 6, also is fixedly connected through key pin 5 between the inner ring of freewheel clutch 7 and the brake axle 6.Have two oil storage tanks 33 on the universal floating disc 3, guaranteed the sufficient lubrication of device, prolonged service life.Brake disc 4, universal floating disc 3, torque plate 2 adopts high-abrasive materials to make, and fully lubricated, and brake disc 4, universal floating disc 3, torque plate 2 self torsional resistance is very little, thereby also guaranteed the flexibility of the clockwise cycle of mantle.
During work, when mantle turns clockwise, freewheel clutch 7 allows mantles freely to rotate; When mantle rotated counterclockwise, freewheel clutch 7 check brake axles 6 stoped brake disc 4 to rotate, thereby stoped universal floating disc 3 to rotate, and then stoped mantle to rotate counterclockwise; When mantle rotates counterclockwise moment above permissible value, cutting off screw 8 will be cut off, thus other part on protection freewheel clutch 7 and the unidirectional Device for preventing rotation.
The foregoing description is to explanation of the present invention, is not to qualification of the present invention, any scheme after the simple transformation of the present invention is all belonged to protection scope of the present invention.
