Description
Technical field
The utility model relate to one can fundamentally avoid large-scale conical sand making Machine-made Sand discharge gate cross iron thickness exceed discharge gate maximum open measure time; to the large-scale circular cone sand making machine with automatic protection functions that circular cone sand making machine upper spider and lower bearing bracket damage, belong to large-scale conical sand making machine and manufacture field.
Background technology
CN102357371A, title " a kind of multicylinder hydraulic rolling bearing circular cone sand making machine ", comprise lower framework, excentric sleeve mechanism, transmission group, mantle, upper stand group and excessively iron and clear chamber device, described upper stand group is located at the top of lower framework, transmission group and excentric sleeve mechanism are installed on lower framework, transmission group is connected with excentric sleeve mechanism, excentric sleeve mechanism is provided with mantle, described lower framework and upper stand group were directly provided with iron and clear chamber device, it is characterized in that: described excentric sleeve mechanism adopts rolling bearing type excentric sleeve mechanism, cross iron and clear chamber device adopts Relief Valve to cross iron and clear chamber device, movable cone device for preventing rotation is also connected with bottom mantle.Its weak point: be positioned at hanger on the multiple stage pressurize cylinder lower end hanger of circular cone sand making machine surrounding and lower bearing bracket and adopt carbon steel pivot pin pin joint, pressurize cylinder upper end and upper spider link together, when circular cone sand making machine crosses iron (running into iron block), range number of elements millimeter on upper spider, its discharge gate increases to several millimeters, when the thickness running into iron block exceeds the maximum discharging bore of discharge gate, pressurize cylinder Overstroke (in machinery tension), mechanical strength due to carbon steel pivot pin is high cannot be broken, cause pivot pin by upper spider, pressurize cylinder, lower bearing bracket and hanger draw distortion or damage, for thickness at several centimetres of hangers, once draw distortion to be difficult to repair.
Utility model content
Purpose of design: keep away the weak point in many background technologies; design one can fundamentally avoid large-scale conical sand making Machine-made Sand discharge gate cross iron thickness exceed discharge gate maximum open measure time, to the large-scale circular cone sand making machine with automatic protection functions that circular cone sand making machine upper spider and lower bearing bracket damage.
Design: in order to realize above-mentioned purpose of design.1, the lower hanger on the pressurize cylinder lower end in large-scale circular cone sand making machine upper spider on hanger and lower bearing bracket adopts the design of gray iron pivot pin socket connection, is one of technical characteristic of the present utility model.The object done like this is: due to grey cast-iron phosphorus content higher (2.7% ~ 4.0%), and carbon mainly exists with flake graphite form, and metallographic structure is ferrite+flake graphite+pearly-lustre body heat, and therefore gray iron does not have yield strength.The application utilizes this feature of gray iron to make pivot pin just, when the discharge gate of conical sand making mechanism sand runs into the iron block exceeding discharge gate maximum open footpath, because the pivot pin adopting gray iron to make does not have yield strength, therefore pressurize cylinder lower end hanger and lower bearing bracket hanger cut off the pivot pin that gray iron can make by the shearing force contrary each other that gray iron pivot pin is formed, ensure that the hanger in the upper and lower frame of pressurize cylinder can not be pulled out of shape, the equipment of ensure that can not be damaged; Secondly because the graphite in gray iron has good greasy property, it can play hanger lubrication, reduces the frictional resistance between hanger and gray iron pivot pin.2, the axle portion hangers supporting part hoop of gray iron pivot pin has the design of overload snap slot, is technical characteristic two of the present utility model.The object of such design is: because the hoop of the axle portion hangers supporting part at gray iron pivot pin has overload snap slot; the power that this annular overload snap slot portion carries is less than other pivot pin portion; therefore when the hanger being positioned at the pressurize cylinder lower end inside and outside annular overload tank is haled gray iron pivot pin because of overload; under the shear action of gray iron pivot pin hanger on pressurize cylinder lower end hanger and lower bearing bracket; its gray iron pivot pin hangers supporting part two ends annularly snap slot are pulled off; both protected equipment, and be convenient to again change.
Technical scheme: a kind of large-scale circular cone sand making machine with automatic protection functions; comprise large-scale circular cone sand making machine; described large-scale circular cone sand making machine upper spider surrounding is provided with multiple stage pressurize cylinder; multiple stage pressurize cylinder lower end has upper hanger respectively; lay respectively on lower bearing bracket with hanger under upper hanger, upper hanger to insert between lower hanger and adopts gray iron pivot pin to connect.
The utility model is compared with background technology, and one is not only fundamentally solve circular cone sand making machine discharging to make a slip of the tongue the damage caused pressurize cylinder, hanger and frame in circular cone sand making machine upper spider and lower bearing bracket when iron exceedes discharging opening maximum the first transaction of a day's business stroke; Two is make the replacing of gray iron pivot pin become providing for simple replacement of of normality.
