Abstract
The utility model discloses a kind of impact resistant buffer device, comprise fixed bearing, erection of main beam seat, be connected and fixed the buffering connecting rod of bearing and erection of main beam seat, be arranged in fixed bearing and erection of main beam seat, bump rubber between buffering connecting rod and fixed bearing or erection of main beam seat, for the bolt fastener of fixing buffering connecting rod and bump rubber.The utility model bump rubber is compressed distortion, take fixed bearing as the center of circle, to cushion connecting rod for radius, one section of arc length is cushioned along this circular arc, reach buffering effect, only move on belt direction of travel is under circular arc in buffering course, stop the phenomenon that swings, belt conveyor sideslip can not be produced, the working environment that long service life, shock resistance are good, distance, high belt speed, large conveying quantity are grown in adaptation.
Description
Technical field
The utility model relates to a kind of impact resistant buffer device, belongs to mine mechanism technical field.
Background technology
Usually buffering support roll-type, buffering sliding strip type buffering method and spring buffer structure is adopted at the bearing mode at belt conveyer blanking bearing point position in existing market, all there is certain defect in the buffering of these three kinds of modes, the shortcoming that wherein impact idler structure exists is: 1. load-transfer device is larger by the unsettled section of snap tension caused; 2. being interrupted support makes load-transfer device more easily tear; 3., when running into impact idler and damaging, resistance increases the overall operation of impact; 4. impact when causing buffering apron discontinuity, cause belt deflection; 5. impact idler is fragile, and service life is short.And cushion the shortcoming that draw runner structure exists and be: 1. adopt buffering draw runner to have gap equally, large equally to the snap tension at unsettled section of load-transfer device place, to load-transfer device to tear possibility also large; 2. cushion draw runner to be formed by multiple wall scroll support combinations, fragile under the impact of weight discharging point, and manufacturing cost is high.Spring buffer structural disadvantages is: this structure makes integral device randomness rock, although solve buffering effect, easily causes belt deflection phenomenon to occur.
Visible, it is short, fragile all to there is service life in above three kinds of buffer structures, and manufacturing cost is high, under the work condition environment of inadaptable long distance, high belt speed, large conveying quantity, therefore, needs a kind of impact resistant buffer device that can solve the problem.
Utility model content
For overcoming the deficiencies in the prior art, the utility model provides the impact resistant buffer device of working environment that a kind of long service life, shock resistance are good, adapt to long distance, high belt speed, large conveying quantity.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of impact resistant buffer device, comprise fixed bearing, erection of main beam seat, be connected and fixed the buffering connecting rod of bearing and erection of main beam seat, be arranged in fixed bearing and erection of main beam seat, the bump rubber between buffering connecting rod and fixed bearing or erection of main beam seat, for the bolt fastener of fixing buffering connecting rod and bump rubber.
Further, the inner chamber of described fixed bearing and erection of main beam seat is set to square cavity, the part that buffering connecting rod is positioned at fixed bearing and erection of main beam seat cavity is set to square, the intermediate point of the four edges of the square cavity of its tetragonal four vertex correspondence fixed bearings and erection of main beam seat, bump rubber arranges four pieces, is arranged on respectively between buffering connecting rod four limit and square cavity.
Advantageous Effects of the present utility model is: bump rubber is compressed distortion, take fixed bearing as the center of circle, to cushion connecting rod for radius, one section of arc length is cushioned along this circular arc, reach buffering effect, only move on belt direction of travel is under circular arc in buffering course, stop the phenomenon that swings, belt conveyor sideslip can not be produced, the working environment that long service life, shock resistance are good, distance, high belt speed, large conveying quantity are grown in adaptation.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described further.
Fig. 1 is the utility model structural representation;
Fig. 2 is the A-A section-drawing of Fig. 1;
Fig. 3 is the B-B section-drawing of Fig. 1.
In figure: 1, fixed bearing, 2, erection of main beam seat, 3, buffering connecting rod, 4, bolt fastener, 5 bump rubbers.
Detailed description of the invention
A kind of impact resistant buffer device as shown in Figure 1, 2, 3, comprise fixed bearing 1, erection of main beam seat 2, be connected and fixed the buffering connecting rod 3 of bearing and erection of main beam seat, be arranged in fixed bearing and erection of main beam seat, bump rubber 5 between buffering connecting rod and fixed bearing or erection of main beam seat, for the bolt fastener 4 of fixing buffering connecting rod and bump rubber.
The inner chamber of described fixed bearing 1 and erection of main beam seat 2 is set to square cavity, the part that buffering connecting rod 3 is positioned at fixed bearing and erection of main beam seat cavity is set to square, the intermediate point of the four edges of the square cavity of its tetragonal four vertex correspondence fixed bearings 1 and erection of main beam seat 2, bump rubber 5 arranges four pieces, is arranged on respectively between buffering connecting rod 3 four limit and square cavity.
Erection of main beam seat 2 is in aggregates with Main Girder Welding, girder carries weight, when weight drops in overall anti tear shock absorber equipment continuously, bump rubber 5 is compressed distortion, and impact resistant buffer device can with fixed bearing 1 for the center of circle, to cushion connecting rod 3 for radius, cushion one section of arc length along this circular arc, reach buffering effect, this device only moves in buffering course on belt direction of travel is under circular arc, stop the phenomenon that swings, belt conveyor sideslip can not be produced.The working environment that long service life, shock resistance are good, distance, high belt speed, large conveying quantity are grown in adaptation.
Although give detailed description and explanation to detailed description of the invention of the present utility model above; but what should indicate is; we can carry out various equivalence according to conception of the present utility model to above-mentioned embodiment and change and amendment; when its function produced does not exceed the content that specification sheets contains yet, all should within protection domain of the present utility model.
