Abstract
The invention relates to a sealing compressing device (7) for a mill. The sealing compressing device comprises a sealing ring (1), a pressing plate (2), a compressing ring (3), a steel wire rope (4), a tensioning frame (5) and a bolt and a nut (6), wherein a contact surface of the sealing ring and a mill slipper rolling ring (11) is of herringbone and filled with a lubricant of molybdenum disulfide inside; a first external end face (1-1) of the sealing ring is clung to a mill slipper cover (9); the compressing ring is arranged at a second external end face (1-2) of the sealing ring, and a pressing plate provided with a pressing plate hole (2-1) presses on the compressing ring; a bracket (12) provided with a bracket hole (12-1) is arranged on the mill slipper cover; the bolt and the nut pass through the bracket hole and the pressing plate hole; one end face of the tensioning frame presses an external round face (1-3) of the sealing ring, and the steel wire rope passes through the other end of the tensioning frame; after passing through the tensioning frame, two heads of the steel wire rope respectively pass through angle steels (10) at the lower part of the mill slipper cover, and are buckled by rope fixtures (8).
Description
Technical field
The present invention relates to the tube mill that a kind of grinding material is used.Be a kind of tube mill sealing hold down gag specifically.
Background technology
In cement industry, using maximum is various types of tube mills, and it is a kind of of flour mill, and two ends have the cylinder of supporting arrangement, interior dress abrasive body or abrasive media.Cylinder is around its horizontal center line axis revolution, and the abrasive media frictionally falls again after being brought to certain altitude, and material through cylinder, constantly impacts, pushes thereby receive abrasive media continuously, and final grinding becomes qualified products.The crawler shoe supporting arrangement is the important component part of grinding machine, and the crawler shoe case is static during equipment operation, and slip ring moves in a circle always, and the seal between the two of relative motion usually because wear and tear and unbalance stress, need regularly be adjusted and compressed.Existing device steps nowadays maximizes, and the slip ring diameter also increases thereupon, how to adjust and compress the sealing device easily, guarantees the sealing of crawler shoe supporting arrangement, is the technological difficulties of grinding machine design always.
Summary of the invention
To above problem, the invention provides a kind of grinding machine sealing hold down gag, be used for the sealing of crawler shoe supporting arrangement, it can be adjusted and compressing sealing element easily and effectively, reduces the seepage phenomenon of lubricating oil, guarantees the good lubricated environment of grinding machine.
To the invention provides a kind of grinding machine sealing hold down gag in order overcoming the above problems, to comprise sealing ring, pressing plate, hold-down ring, steel wire rope, tensioning frame and bolt and nut;
The contact-making surface of sealing ring and the rolling ring of grinding machine crawler shoe is " people " font, interior filling Molykote; Sealing ring first outer face and grinding machine crawler shoe are fitted, and second outer face of sealing ring is provided with hold-down ring, is pressed with pressing plate on the hold-down ring; Pressing plate is provided with plate hole; Grinding machine crawler shoe cover is provided with support, and support is provided with bracket holes; Bolt and nut passes bracket holes and plate hole; One end face of tensioning frame is pushed down the periphery of sealing ring, and the other end is installed with steel wire rope, and behind the steel wire penetrating tensioning frame, two is passed respectively behind the angle steel of grinding machine crawler shoe cover bottom by the rope clamp fastening.
Beneficial effect: apparatus of the present invention can effectively avoid seal to cause the phenomenon of poor sealing generation leakage of oil because of wearing and tearing or distortion.Guarantee the lubricated environment of crawler shoe good support, thereby can effectively reduce problems such as the crawler shoe supporting arrangement causes that because of insufficient lubrication holder watt heating, service life lack.That the sealing hold down gag has is simple in structure, characteristics such as easy to adjust and safe and reliable to operation are installed.
Description of drawings
Fig. 1 is for having installed grinding machine sealing hold down gag operation principle sketch map of the present invention;
Fig. 2 is grinding machine sealing hold down gag structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is done further description.
Like Fig. 1, shown in 2, a kind of grinding machine sealing hold down gag 7 comprises sealing ring 1, pressing plate 2, hold-down ring 3, steel wire rope 4, tensioning frame 5 and bolt and nut 6;
Grinding machine crawler shoe cover 9 is provided with support 12, and support 12 is provided with bracket holes 12-1;
Bolt and nut 6 passes bracket holes 12-1 and plate hole 2-1;
One end face of tensioning frame 5 is pushed down the periphery 1-3 of sealing ring 1, and the other end is installed with steel wire rope 4, and after steel wire rope 4 passed tensioning frame 5, two was passed angle steel 10 backs of grinding machine crawler shoe cover 9 bottoms respectively by rope clamp 8 fastenings.
The screwing force of described adjustment bolt and nut 6 can be adjusted the applying degree of sealing ring 1 outer face and grinding machine crawler shoe easily.
The tension that described tensioning frame 5 receives steel wire rope 4 compresses sealing ring 1 equably, and adjustment steel wire rope 4 can be adjusted the thrust of all tensioning frames on the circumference fast uniformly, makes sealing ring 1 can be in impaction state always.Guarantee that with this sealing ring 1 still can fit tightly with the rolling ring of grinding machine crawler shoe after wearing and tearing.
Described sealing hold down gag 7 circumference uniform distributions are on grinding machine crawler shoe cover 9 (as shown in Figure 2).
The tightening force of said steel wire rope 4 can quick adjustment apparatus of the present invention in the thrust of tensioning frame 5.
Apparatus of the present invention circumference uniform distribution is on grinding machine crawler shoe cover, and fixed tensioning is in crawler shoe cover lower end.This contrive equipment, good sealing effect, simple and compact for structure, easy for installation, adaptability is strong.Simultaneously can adjust thrust effectively apace, save manpower and time required when the grinding machine sealing is regulated, also improve the overall performance of equipment.
The above is merely the preferred embodiments of the present invention, is not restricted to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.All within spirit of the present invention and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the claim scope of the present invention.
