Abstract
The utility model provides an idler device for a belt conveyer. The utility model is composed of an idler support frame, a cotter pin, a lifting eye, a bearing body, a spring idler, etc., wherein, an idler shaft sleeve is arranged in the bearing body and is hung in the lifting eye; the lifting eye is fixed on the idler support frame by the cotter pin; the lifting eye adopts an eccentric structure, which causes the length of the spring idler to be adjusted. The utility model has the advantages of simple structure, easy fabrication, and convenient installation and cleaning. Besides, the impact between a belt and an idler is reduced, and the service lives of the belt and the idler are extended.
Description
The utility model relates to a kind of support roller device of belt transporter.
What the belt transporter upper supporting roller generally all used at present all is groove profile carrier roller, promptly form a line and form one group and belt movement direction and be vertically mounted on the belt frame by the roller coaxial line of three same sizes, because carrying roller is that solid drawn pipe is made bobbin, two ends add bearing and are fixed on the roller rack with axle, and belt bears is reverse load, especially belong to when resembling the hard material of ore one class ore deposit shape when the belt convey materials, produce between material and the carrying roller and impact, the belt running resistance is big, serious wear, the life-span of carrying roller is also short, average is about 6 months, ZL90215932.1 discloses a kind of adjustable spring carrying roller, and it provides a kind of improvement trend of carrying roller, but it is far from satisfying the carrying roller distortion from structure, reach problems such as distortion back adjustment.
The utility model improves spring-loaded idler, hanger, support etc. at the problem that above-mentioned carrying roller exists, and has solved its adjustment and problem on deformation.
The utility model is to realize like this, it adopts carrying roller, support, hanger, bearing body, carrying roller etc., its carrying roller adopts spring structure, hanger is an eccentric structure, bearing body is made of two circular cone thrust bearings, and eccentric hanger is fixed on the support by spring cotter, can Rotate 180 °, the axle sleeve of spring-loaded idler and hangs in the hanger in bearing body.
The utility model is done following regulation to its spring-loaded idler roll body size, the carrying roller of belt specification 650～1400mm, the joint square is t=20～24mm, spring wire diameter d=14～16mm, carrying roller nominal diameter D=104～106mm, this scantling of structure of the long 685～1470mm of carrying roller roll body has satisfied the needs of band conveyor reverse load.
The utility model is owing to adopted spring-loaded idler, make between belt and carrying roller and alleviate impact wear, adopted eccentric hanger to be convenient to adjust the distortion of carrying roller, adopt two cover circular cone thrust bearings can make carrying roller bear bigger axial force simultaneously and prevented sideslip, it is simple in structure, be easy to make, and be convenient to install and the cleaning belt holder, increase the service life of belt and carrying roller.
Below in conjunction with accompanying drawing the utility model is done and to be specified.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the scantling of structure figure of spring-loaded idler roll body.
As shown in Figure 1, the utility model has adopted carrying roller 5, support 1, hanger 3, bearing body etc., hanger 3 adopts eccentric structure, is fixed on the support 1 by spring cotter 2, and bearing body 4 is made of two circular cone thrust bearings, the axle 6 of spring-loaded idler 5 is sleeved in two cover circular cone thrust bearings 4, hangs in the hanger 3.When spring-loaded idler roll body 5 elongation, spring cotter 2 is transferred to, spring-loaded idler and bearing body are proposed, the hanger Rotate 180 ° is penetrated spring cotter 2 again, and bearing 4 and spring-loaded idler 5 are hung, like this can be with the certain scantling of structure of spring-loaded idler adjustment of elongation.Support two ends hanger 3 can so be adjusted, and has prolonged the operating cycles of carrying roller, adopts two cover circular cone thrust bearings can make carrying roller bear bigger axial force, and prevents belt deviation.
As shown in Figure 2, spring-loaded idler 5 roll bodies require the structure of spring-loaded idler 5 roll bodies is done following regulation according to different size: to the carrying roller of bandwidth 650～1400mm, joint square t=20～24mm, spring wire diameter d=14～16mm, nominal diameter D=104～106mm, as the belt of specification 650, its spring-loaded idler roll body pitch t adopts 22mm, steel wire diameter d=14mm, the long L=685mm of spring-loaded idler roll body.
