Abstract
The utility model relates to a lifting machine head seal structure. Including head axle and lifting machine head casing, still include the suit at epaxial sealed frame of head and the seal plate who is used for compressing the graphite packing, sealed frame is connected with lifting machine head casing, and the main shaft is worn out from sealed frame, is provided with the graphite packing between sealed frame and the main shaft, and seal plate passes through adjusting bolt with sealed frame and is connected, and distance between adjusting bolt adjustment seal plate and the sealed frame makes seal plate compression graphite packing seal the main shaft. The utility model discloses through the degree that compresses tightly of adjustment graphite packing in the lifting machine operation process, control the dust excessive at any time, can adjust sealed clearance at any time through adjusting bolt, graphite packing is inseparabler with the main shaft laminating after the compression, plays good sealed effect, because graphite packing itself contains graphite element and has fine lubricated effect, so can not produce very big frictional force with the main shaft contact, the operation is more steady, sealed effect is better, simple structure, the adjustment is convenient.
Description
Technical Field
The utility model relates to a bucket elevator specifically is a lifting machine head seal structure.
Background
When the bucket elevator runs, the carrying mechanism moves from bottom to top around the head shaft and then discharges materials from the discharge port downwards through the highest point, a large amount of dust is generated when the materials are discharged, and the dust which is not well sealed can be discharged from a gap between the main shaft and the head shell; at present, the bucket elevator head generally adopts felt seal structure, and this kind of seal structure makes simply, but sealed effect is relatively poor, and it is excessive to have a large amount of dusts when carrying powdery material, and this kind of structure can not satisfy the environmental protection requirement along with the increase of environmental protection dynamics.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the problem, thereby providing a sealed effectual, operate steadily, adjust convenient lifting machine head seal structure.
The utility model provides a problem, the technical scheme who adopts is:
the utility model provides a lifting machine head seal structure, includes head axle and lifting machine head casing, still includes the suit at epaxial sealed frame of head and the seal plate who is used for compressing graphite packing, and sealed frame is connected with lifting machine head casing, and the main shaft is worn out from sealed frame, is provided with graphite packing between sealed frame and the main shaft, and seal plate passes through adjusting bolt with sealed frame and is connected, through the distance between adjusting bolt adjustment seal plate and the sealed frame, makes seal plate compression graphite packing seal the main shaft.
Adopt above-mentioned technical scheme the utility model discloses, compare with prior art, its outstanding characteristics are:
the head sealing device is arranged between the main shaft and the shell, so that the problem of dust overflow can be well solved, and the dust overflow can be controlled at any time by adjusting the compression degree of the graphite packing in the operation process of the elevator.
The graphite packing has the advantages that the sealing gap can be adjusted at any time through the adjusting bolt, the compressed graphite packing is attached to the main shaft more tightly, a good sealing effect is achieved, the graphite packing contains graphite elements and has a good lubricating effect, so that the graphite packing does not generate large friction when contacting with the main shaft, the operation is more stable, the sealing effect is better, the structure is simple, and the adjustment is convenient.
Preferably, the present invention further provides:
the flange end faces of the sealing pressure plate and the sealing frame are evenly provided with corresponding bolt holes and are connected through adjusting bolts and nuts.
An annular groove is formed between the sealing frame and the main shaft, and the graphite packing is arranged in the annular groove.
The extrusion end of the sealing pressure plate is arranged in the annular groove and can slide on the main shaft under the action of the adjusting bolt.
Drawings
FIG. 1 is a schematic structural diagram of an embodiment of the present invention;
in the figure: sealing the pressure plate 1; an adjusting bolt 2; a sealing frame 3; a graphite packing 4; a head shaft 5; a nut 6; an annular groove 7.
The specific implementation mode is as follows:
the invention will be further described with reference to the following examples, which are intended only for better understanding of the invention and therefore do not limit the scope of the invention.
Referring to fig. 1, a head sealing structure of a lifter comprises a sealing pressure plate 1, an adjusting bolt 2, a sealing frame 3 and a graphite packing 4, wherein the sealing pressure plate 1 and the sealing frame 3 are both sleeved on a head shaft 5, the sealing frame 3 is fixedly connected with a lifter head shell through a bolt, a main shaft 5 penetrates out of the sealing frame 3, the graphite packing 4 is arranged between the sealing frame 3 and the main shaft 5, and the distance between the sealing frame 3 and the sealing pressure plate 1 is adjusted through the adjusting bolt 2 so as to achieve the effect of compressing the graphite packing 4 to seal the main shaft 5; twist adjusting bolt 2 at lifting machine operation in-process, sealing plate 1 can the inward movement, and sealing plate 1 can be compressed with the graphite packing 4 in the seal frame 3, and graphite packing 4 is inseparabler with the 5 laminating of main shaft after the compression, plays good sealed effect, because graphite packing itself contains graphite element and has fine lubricated effect, so can not produce very big frictional force with 5 contacts of main shaft, and it is better to operate more steady sealed effect.
The flange end faces of the sealing pressure plate 1 and the sealing frame 3 are evenly provided with corresponding bolt holes and are connected through the adjusting bolts 2 and the nuts 6.
An annular groove 7 is formed between the sealing frame 3 and the main shaft 5, and the graphite packing 4 is arranged in the annular groove 7.
The extrusion end of the sealing pressure plate 1 is arranged in the annular groove 7 and can slide on the main shaft 5 under the action of the adjusting bolt 2.
The utility model discloses install this head sealing device can be fine solution dust excessive problem between main shaft 5 and casing, can be through the degree that compresses tightly of adjustment graphite packing 4 at lifting machine operation in-process, it is excessive to control the dust at any time, through adjusting bolt 2, can adjust sealed clearance at any time, graphite packing 4 is inseparabler with the laminating of main shaft 5 after the compression, play good sealed effect, because graphite packing 4 itself contains graphite element and has fine lubricated effect, so can not produce very big frictional force with the contact of main shaft 5, the operation is more steady, sealed effect is better, moreover, the steam generator is simple in structure, the adjustment is convenient.
The above description is only a preferred and practical embodiment of the present invention, and not intended to limit the scope of the present invention, and all equivalent variations made by using the contents of the specification and the drawings are included in the scope of the present invention.
