Description

a kind of gyratory crusher determine cone frame

Technical field

The present invention relates to mining equiment field, what particularly relate to a kind of gyratory crusher determines cone frame.

Background technology

Gyratory crusher is a kind of mining machinery for broken building stones, and to be the mantle group of being rotated by swing coordinate for broken building stones with surely boring mutually to extrude between frame its operation principle; During broken building stones, building stones enter machine frame inside by the frame upper end of gyratory crusher, carry out fragmentation at machine frame inside.But, existing gyratory crusher to determine cone shelf structure single, intensity is not enough; Surely bore frame to comprise and rigidly connectedly determine cone and surely bore liner plate, in the process of broken building stones, cone crusher chance produces substantial load, rigidly connected liner plate of surely boring can make frame produce sharp pounding, frame is in the collision of long-time vibrations and building stones, very easily produce crack, have a strong impact on its service life.

Summary of the invention

In order to solve the problem, the object of the present invention is to provide the fixed cone of cone crusher frame that a kind of bonding strength is high, anti seismic efficiency is good.

In order to realize above-mentioned object, present invention employs following technical scheme:

Gyratory crusher determine a cone frame, comprise and determine cone, and be arranged on determine cone inside determine cone liner plate; Described determine cone comprise be in outside determine cone adjustable ring, and be in determine cone adjustable ring inside determine cone fixed cover, and be arranged on and determine cone fixed cover, surely many groups of boring between adjustable ring and surely bore Connection Block and Duo Gen determines cone reinforcement; The bottom of surely boring fixed cover is connected with the bottom of surely boring adjustable ring one, surely Connection Block is bored and Duo Gen determines the spaced annular array of cone reinforcement for many groups, surely bore Connection Block and determine cone reinforcement outer end all with surely bore adjustable ring and be integrally connected, surely cone Connection Block and the inner end determining cone reinforcement all with surely bore fixed cover and be integrally connected;

Described inside of surely boring Connection Block communicates with the inside of surely boring fixed cover, surely bore liner plate in the taper determined cone fixed cover and match, the outer side surface of surely boring liner plate is also provided be connected as a single entity with it determine taper pin seat, determine taper pin seat with surely bore on fixed cover determine cone Connection Block mate, corresponding, determine taper pin seat by surely boring syndeton and surely bore Connection Block and be connected and fixed; Described syndeton of surely boring comprises lining-plate bolt, liner plate nut, disk spring, spring fairlead and packing ring, the upper end of lining-plate bolt is male threaded joint, the lower end of lining-plate bolt is articulated section, the bottom of lining-plate bolt by bearing pin with to determine taper pin seat hinged, the upper end of lining-plate bolt is fixed by liner plate nut after surely boring Connection Block, spring fairlead and packing ring are set in liner plate nut from outside to inside successively and surely bore on the lining-plate bolt between Connection Block upper surface, disk spring is set on spring fairlead, and bottom and the packing ring of disk spring cover offset.

As preferably, surely boring fixed cover is that upper end diameter is little, the taper that lower end diameter is large.

The present invention adopts technique scheme, and this is surely bored and determines cone by surely boring adjustable ring, surely boring fixed cover, surely boring Connection Block and determine cone reinforcement and integrally connect and compose in frame, strengthens the bonding strength determining cone on the whole; The outside of surely boring liner plate is provided with corresponding with determining cone Connection Block determines taper pin seat, determines taper pin seat and surely bore between Connection Block to flexibly connect by surely boring syndeton, wherein surely bores that disk spring in syndeton coordinates spring fairlead, packing ring plays damping effect; The bottom of surely boring lining-plate bolt in syndeton with determine taper pin seat hinged by bearing pin, thus can be made to determine cone liner plate and can the swing centered by bearing pin cushion when broken building stones; Comprehensive overall structure of surely boring frame, bonding strength is high, anti seismic efficiency is good advantage that it has.

Detailed description of the invention

Below in conjunction with accompanying drawing, the preferred embodiments of the invention are described in further detail.

A kind of gyratory crusher as shown in Fig. 1 ~ Fig. 3 determine cone frame, comprise and determine cone 1, and be arranged on determine cone 1 inside determine cone liner plate 2; Described determine cone 1 comprise be in outside determine cone adjustable ring 11, and be in determine cone adjustable ring 11 inside determine cone fixed cover 12, and be arranged on and determine cone fixed cover 12, surely many groups of boring between adjustable ring 11 and surely bore Connection Block 13 and Duo Gen determines cone reinforcement 14; The bottom of surely boring fixed cover 12 is connected with the bottom one of surely boring adjustable ring 11, surely Connection Block 13 is bored and Duo Gen determines the spaced annular array of cone reinforcement 14 for many groups, surely bore Connection Block 13 and determine cone reinforcement 14 outer end all with surely bore adjustable ring 11 and be integrally connected, surely cone Connection Block 13 and the inner end determining cone reinforcement 14 all with surely bore fixed cover 12 and be integrally connected;

Described inside of surely boring Connection Block 13 communicates with the inside of surely boring fixed cover 12, surely fixed cover 12 is bored little in upper end diameter, the taper that lower end diameter is large, surely bore liner plate 2 in the taper determined cone fixed cover 12 and match, surely bore liner plate 2 outer side surface on be also provided be connected as a single entity with it determine taper pin seat 21, determine taper pin seat 21 with surely bore on fixed cover 12 determine cone Connection Block 13 mate, corresponding, determine taper pin seat 21 by surely boring syndeton and surely boring Connection Block 13 and be connected and fixed, described syndeton of surely boring comprises lining-plate bolt 31, liner plate nut 32, disk spring 33, spring fairlead 34 and packing ring 35, the upper end of lining-plate bolt 31 is male threaded joint, the lower end of lining-plate bolt 31 is articulated section, the bottom of lining-plate bolt 31 by bearing pin with to determine taper pin seat 21 hinged, the upper end of lining-plate bolt 31 is fixed by liner plate nut 32 after surely boring Connection Block 13, spring fairlead 34 and packing ring 35 are set in liner plate nut 32 from outside to inside successively and surely bore on the lining-plate bolt 31 between Connection Block 13 upper surface, disk spring 33 is set on spring fairlead 34, bottom and the packing ring of disk spring cover offset.

In sum, this is surely bored and determines cone by surely boring adjustable ring, surely boring fixed cover, surely boring Connection Block and determine cone reinforcement and integrally connect and compose in frame, strengthens the bonding strength determining cone on the whole.The outside of surely boring liner plate is provided with corresponding with determining cone Connection Block determines taper pin seat, determines taper pin seat and surely bore between Connection Block to flexibly connect by surely boring syndeton, wherein surely bores that disk spring in syndeton coordinates spring fairlead, packing ring plays damping effect; The bottom of surely boring lining-plate bolt in syndeton with determine taper pin seat hinged by bearing pin, thus can be made to determine cone liner plate and can the swing centered by bearing pin cushion when broken building stones; Comprehensive overall structure of surely boring frame, bonding strength is high, anti seismic efficiency is good advantage that it has.
