Description
Technical field
The utility model relates to technical field of engineering machinery, more particularly to a kind of locking for gyratory crusher
Mechanism.
Background technique
Gyratory crusher be it is a kind of suitable for metallurgy, build, build the road, chemistry and silicate industry raw material crusher
Tool.It is of different sizes according to the difference and product particle of smashing principle, and it is divided into many models.Crusher be widely used in mine,
Numerous departments such as smelting, building materials, highway, railway, water conservancy and chemical industry.Cone crushing is than big, high-efficient, energy consumption
Low, product granularity is uniform, be suitble in broken and fine crushing various ores, rock.Type is broadly divided into SMG series, spring type and HPC system
Column, are respectively described their working principle, structure etc..Also describe developing history, the work of gyratory crusher in detail
Make principle, composition, influence factor, technical advantage, operation item, most common failure and maintenance and inspection etc..
With the continuous development of mine technology, gyratory crusher is also classified into several kinds, according to type includes that spring circular cone is broken
Broken machine rolls that mortar formula circular cone is broken, 4 major class of hydro cone-crusher and compound gyratory crusher；It is divided into common PY according to model
Gyratory crusher, simon this gyratory crusher, compound gyratory crusher, standard hydro cone-crusher, single-cylinder hydraulic circular cone are broken
All polytypics such as broken machine and multicylinder hydraulic spindle breaker.Fluid pressure type crusher is to digest and assimilate international most advanced level
It is developed on the basis of all types of gyratory crushers.It is significantly different in design with the structure of traditional gyratory crusher,
And the major advantage of hitherto known all types of gyratory crushers is concentrated.It is suitable for fine crushing and super fine crushing is hard
Rock, ore, slag, refractory material etc..
Gyratory crusher structure brief introduction: the main organic frame of its structure of gyratory crusher, trunnion axis, movable cone, stabilizer, partially
Heart set, upper crushing wall (fixed cone), lower crushing wall (mantle), fluid-flywheel clutch, lubricating system, hydraulic system.In cone crusher
In the course of work of machine, motor drives eccentric bushing to rotate by transmission device, mantle excentric sleeve it is forced to move under do and rotate
Swing, mantle becomes crusher chamber close to the section of quiet cone, material by mantle and quiet cone multiple extruding and hit and be crushed.
It has been crushed to when mantle leaves the section, at this and the material of granularity is required to fall under self gravitation effect, be discharged from cone bottom.
The retaining mechanism of traditional gyratory crusher is by hydraulic system or spring by locking cylinder, however retaining mechanism is
Very big pulling force is needed by rack and retaining ring, locking cylinder are fixed, especially needs to allow hydraulic pressure system when hydraulic locking
The rated pressure of system is sufficiently large just to can ensure that crushing wall (fixed cone) is fixed, therefore traditional locking device waste of energy.
