Abstract
The invention provides a grinding roller limiting device for a vertical grinder. By the grinding roller limiting device, the height of a grinding roller can be set accurately, a clearance between the grinding roller and a grinding disk is guaranteed, equipment can run safely, and faults are reduced. According to the grinding roller limiting device for the vertical grinder, the grinding roller is arranged on an upper rocker arm; the upper rocker arm is arranged on lower rocker arms; and two ends of a rocker arm shaft fixed on the lower rocker arms are arranged on bearing pedestals in a rotatable manner. The grinding roller limiting device is characterized in that fixed baffle plates vertical to the rocker arm shaft are fixed on the bearing pedestals; umbrella-shaped holes are formed in the fixed baffle plates; one end of the rocker arm shaft is fixed with a movable baffle plate; the movable baffle plate is provided with a fan-shaped part extending into the umbrella holes; and when the movable baffle plate is driven by the rocker arm shaft to rotate relative to the fixed baffle plates, the rotation angle of the movable baffle plate is limited because two side walls of the fan-shaped part are contacted with two side walls of each umbrella-shaped hole.
Description
Technical field
Present technique relates to a kind of mechanical stop limiter of Vertical Mill.
Background technology
The Vertical Mill grinding roller relies on hydraulic means, and pressing mechanism puts on the material on the mill with the pulling force that hydraulic cylinder produces, and the material pressurized is ground with the shearing force of mill relative motion generation by grinding roller simultaneously and obtains grinding.Cause bump, wearing and tearing for preventing that grinding roller from contacting with mill, just on support, fix a mechanical stop limiter, withstand lower shake-changing arm, make that the gap minimum is a fixed value between grinding roller and the mill.In actual production process, mechanical stop limiter generally adopts cluster spring or butadiene-styrene rubber at present, and hydraulic cylinder loads the general 6 ~ 8MPa of operating pressure; The mechanical position limitation demand side is to the high-frequency bump of hundreds of ton force; So the requirement to cluster spring and butadiene-styrene rubber circle is very strict, for cluster spring, it can satisfy this working environment basically; But general being difficult to realized under the present level of processing of China enterprise; Basic dependence import, this not only needs high expense, and the cycle of buying is also long.And the butadiene-styrene rubber circle, its elastic deformation is big on the one hand, when setting grinding roller and abrasive disk space, often to carry out repeatedly repeatedly on-load pressure to make an experiment, nor too accurate; Under the working environment of high voltagehigh frequency rate, rubber is easy of crack relatively, can cause immeasurable consequence on the other hand, influences whole production operation progress.So, must design a kind of new mechanical stop limiter, solve the defective in the prior art.
Summary of the invention
The purpose of present technique provides and a kind ofly can reach accurate setting grinding roller height, guarantees grinding roller, abrasive disk space, guarantees equipment safety operation, reduces the grinding roller stopping means of the Vertical Mill of fault.
The grinding roller stopping means of this Vertical Mill, grinding roller is arranged on the upper rocker arm, and upper rocker arm is arranged on the lower shake-changing arm, and the two ends rotation that is fixed on the rocker arm shaft on the lower shake-changing arm is arranged on the bearing block; It is characterized in that: be fixed with fixed dam on the bearing block, have the umbrella shape hole on the fixed dam perpendicular to rocker arm shaft; End at rocker arm shaft is fixed with sideboard, and sideboard has the scallop that extend in the umbrella shape hole; When rotating with respect to fixed dam under the drive of sideboard at rocker arm shaft, owing to the two side of scallop contacts the rotational angle that has limited sideboard with the two side in umbrella shape hole.
Described grinding roller stopping means, the center in said scallop and umbrella shape hole all is axis of rocker arm shaft.Preferably, said umbrella shape hole and scallop all are two, and all the axis with rocker arm shaft is the center symmetry.
Described grinding roller stopping means, sideboard is 7.5 ° with respect to the rotational angle of fixed dam.
Described grinding roller stopping means, rocker arm shaft links to each other with lower shake-changing arm through the swelling cover.
The beneficial effect of present technique: fixed dam and rocker arm shaft bearing are fixed, and sideboard and rocker arm shaft are fixed, and rocker arm shaft is with fixing by the swelling cover.Sideboard is embedded in fixed dam (embedded structure); Sideboard is with respect to the anglec of rotation 7.5 degree of fixed dam; (angle around the rocker arm shaft center of lifting roller and the roller that falls during general mill running is 7 degree); In the grinding roller self gravitation and hydraulic cylinder on-load pressure scope that interior outer baffle bore, can play the effect of restriction grinding roller position.Because grinding machine in the running, has the certain thickness bed of material on the mill, so grinding roller can not be permanently connected to lower limit, so interior outer baffle can not clash into each other yet, wear and tear always, be in not contact condition basically, reduce the grinding machine vibration to a certain extent.

The specific embodiment
Referring to the grinding roller stopping means of Fig. 1, the Vertical Mill shown in 2, grinding roller 1 is arranged on the upper rocker arm 2, and upper rocker arm 2 is arranged on the lower shake-changing arm 3, and the two ends rotation that is fixed on the rocker arm shaft on the lower shake-changing arm through swelling cover 4 is arranged on the bearing block 5.Be fixed with the fixed dam 6 perpendicular to rocker arm shaft on the bearing block 5, having two axis with rocker arm shaft on the fixed dam is centrosymmetric umbrella shape hole 7.Left end at rocker arm shaft is fixed with sideboard 8, and sideboard has two scallop 9 that extend in two umbrella shape holes; Two scallop are the center symmetry with the axis of rocker arm shaft.Outer plate 10 is pressed abd fixed on fixed dam on the bearing block through bolt.Clip plate 11 is pressed abd fixed on sideboard through bolt the end of rocker arm shaft.The inner ring of the bearing in dividing plate 13 and the bearing block contacts.
When rotating with respect to fixed dam under the drive of sideboard at rocker arm shaft, owing to the two side of scallop contacts the rotational angle that has limited sideboard with the two side in umbrella shape hole.Generally speaking, can be through the cooperating of scallop and umbrella shape hole, the qualification sideboard is 7.5 ° with respect to the rotational angle of fixed dam.
We transfer to rocker arm shaft bearing stiff end to the existing mechanical stopping means from frame, and its core component mainly relies on fixed dam, sideboard, swelling cover, interior outer plate.Fixed dam and rocker arm shaft bearing are fixed, and sideboard and rocker arm shaft are fixed, and rocker arm shaft and lower shake-changing arm are fixing by the swelling cover.Sideboard and fixed dam adopt embedded structure (like Fig. 3); The anglec of rotation 7.5 degree that two baffle plates are relative; (angle around the rocker arm shaft center of lifting roller and the roller that falls during general mill running is 7 degree); In the grinding roller self gravitation and hydraulic cylinder on-load pressure scope that interior outer baffle bore, can play restriction grinding roller position.Because grinding machine in the running, has the certain thickness bed of material on the mill, so grinding roller can not be permanently connected to lower limit, so interior outer baffle can not clash into each other yet, wear and tear always, be in not contact condition basically, reduce the grinding machine vibration to a certain extent.When debugging is installed; At first confirm the minimum clearance value T between grinding roller 1 and the mill 12, prepare then under the metal mat placement of respective thickness and the roller that falls that interior outer baffle transfers to lower limit; Swelling puts bolt and is screwed to 1/3 of rated moment; The roller that falls, pressurization is accomplished the back swelling and is overlapped bolt and be screwed to rated moment.Lower limit is just fixing in the dust like this.
