Description
Technical field
The invention belongs to kibbler roll technical field, particularly relate to a kind of breaker teeth board fixing structure.
Background technology
The discaling roll of traditional kibbler roll, primarily of tooth plate and roller composition, tooth plate is cast with connecting hole, roller is drilled with screwed hole, by bolt, tooth plate is fixed on roller.This disintegrating machine runs up under operating conditions, connecting bolt not only plays connection fastening effect, also serve the transmission effect of moment between tooth plate and roller, also huge shearing force will be subject to except being subject to connecting fastening pulling force, once connecting bolt fracture tooth plate will come off from the discaling roll of High Rotation Speed, light like this, destroy equipment, heavy then cause casualties.
In order to avoid tooth plate comes off from roller, Chinese patent CN202290158 adopts dovetail and dovetail groove fit structure, by bolt, tooth plate is fixedly connected with roller, substantially crusher toothed plate outbound problem from roller is solved, safe and reliable, but tooth plate is got the raw materials ready oversize, cause material cost high, dovetail one damages, and tooth plate all damages, and maintenance is inconvenient; And tooth plate with bolts, bolt easily loosens and moves back silk, causes needing often to shut down fastening bolt, and tooth plate dismounting is inconvenient, except causing user maintenance, outside use cost height, has also had a strong impact on the cycle-time efficiency of disintegrating machine.
Chinese patent CN2636984 discloses that a kind of structure is simple, the breaker teeth roll structure of firm position, roller surface there are the wedge groove of voussoir or wedge groove and working panel bottom surface or voussoir coordinate, but this structure adopts locking panel to fix between swallow-tail form voussoir, locking panel installation or removal difficulty, use inconvenience, very difficult when changeing tooth plate, take time and effort, operating efficiency is low; Locking panel needs to carry out fine finishining, manufactures cost higher.
Chinese patent CN201701963 discloses the fastening structure of a kind of crusher roller and tooth plate, roller outer wall arranges boss, tooth plate inwall arranges groove, screwed hole offered by roller, tooth plate is offered the through hole in order to wear bolt coordinated with screwed hole, by screw bolt and nut, roller and tooth plate are locked, solve bolt well easily to loosen and the problem such as fracture, security obtains guarantee, but when dismantling tooth plate, need multiple screw bolt and nut to take off, change tooth plate still not too convenient.
Chinese patent CN202028423 is in order to solve the problem of bolt or insert dismounting difficulty, tooth plate two bottom sides is provided with convex hook, roller surface is provided with limit insert and T-shaped block, tooth plate by interior insert and can along roller in axial sliding sliding sleeve banding be fixed on described roller, with interior insert inside convex hook, limit insert coordinates transmitting torque, sliding sleeve is fixed on roller by the mating reaction of bolt and tapped through hole, tooth plate can not be thrown out of and depart from roller under the effect of sliding sleeve, safe and reliable, and convenient disassembly, only need unload following pressing plate, heel teeth plate can be extracted out and unload, the convex hook distance of twice that sliding sleeve is slid axially, middle tooth plate can be unloaded.But the construction unit that the program adopts is numerous, and convex hook used, limit insert, T-shaped block, interior insert, sliding sleeve, end plate, limit pressing plate etc. all need fine finishining, and enterprise's use cost is very high.
Summary of the invention
In order to solve prior art Problems existing, object of the present invention will provide a kind of breaker teeth board fixing structure exactly, the potential safety hazard that tooth plate departs from roller can be solved, solve the problems such as crusher toothed plate installation is loaded down with trivial details, dismounting difficulty, inefficiency, and greatly can reduce the problem of enterprise's production cost.
To achieve these goals, the technical solution used in the present invention is such: a kind of breaker teeth board fixing structure, comprise with lower unit: tooth plate, roller, square steel tube, rubber hose and jacking block, described roller is evenly distributed with at least two boss, described tooth plate two bottom sides is provided with the projection with boss snap-fit engagement, groove is provided with in the middle of bottom described tooth plate, in described groove, steel pipe is installed, described steel duct is provided with rubber hose, this rubber hose is communicated with external hydraulic system, is provided with several jacking blocks between described steel pipe and rubber hose.
In the tooth plate fixed structure of this disintegrating machine, the boss on described roller adopts casting to form, and the projection on tooth plate adopts casting to form, and during installation, tooth plate loads between adjacent two boss of roller along the radial direction of roller, and installation and removal are convenient; When needs fixed tooth plate, by external hydraulic system to injection liquid force feed in rubber hose, rubber hose volumetric expansion becomes large and promotes jacking block, jacking block is protruding from steel pipe applies pressure to tooth plate, thus held out against tooth plate, boss on tooth plate and roller is firmly fixed, ensure that tooth plate can not throw away from roller and keep not play under the effect of centrifugal force and crushing force; This structure does not need to use bolt or insert to fix, and can not there is bolt looseness and come off, security is protected; The tooth plate fixed structure part component of this disintegrating machine is simple, with low cost, easy to use.When tooth plate changed by needs, only the hydraulic oil in rubber hose need be discharged, tooth plate i.e. automatic and roller departs from, change tooth plate rapid and convenient, greatly increase work efficiency, saved cost, and can continuous operation, without the need to often carrying out the inspection and maintenance of part, this structure can also be applied to each Large Crusher with the crusher structure with many toothrows plate.
Preferably, the interface arrangment between described boss and projection comprises any one shape in T-shaped, I-shaped, swallow-tail form.
Preferably, described steel pipe is square or circular.
Preferably, described steel pipe is provided with some circular holes, described jacking block is installed on circular hole place.
Preferably, the circular hole internal diameter on the internal diameter of described jacking block and steel pipe is consistent.
Preferably, the both sides of described roller are provided with baffle plate, for preventing tooth plate along the axial float of roller.
The present invention's usefulness is compared with prior art: this breaker teeth board fixing structure have employed the structure of the boss on roller and the protruding snap-fit engagement bottom tooth plate, and pass through by external hydraulic system to injection liquid force feed in rubber hose, rubber hose volumetric expansion is utilized to become large and promote jacking block, jacking block is made to apply pressure from the circular hole in steel pipe is protruding to tooth plate, thus held out against tooth plate, boss on tooth plate and roller is firmly fixed, its structure is simple, reasonable in design, easy to use, under the prerequisite ensureing safety in production, achieve the fixing of crusher toothed plate, and tooth plate is changed convenient to disassembly, to save time cost, can continuous seepage, greatly enhance productivity, reduce enterprise's production cost, and may be used for the Large Crusher with many toothrows plate.
