Description
Technical field
The utility model belongs to deviation correcting device technical field, particularly relates to a kind of spiral automatic correcting stone roller.
Background technology
At present, ribbon conveyer is used in coal, metallurgy, building materials, harbour, mine, harbour etc. widely
Industry.Belt conveyer is the important transportation equipment of conveying bulk materials, and carrying roller bears the resistance of 70%.Due to the accumulation of material bias, equipment installs injustice, stand stretch, pulling force is not enough or the unequal reason of tension distribution can cause the skew of belt, tear or phenomenon of rupture, affects the running quality of Belt Conveying.The deviation phenomenon of belt conveyer is still current insoluble chronic disease.Also there is technical personnel to study correction problem in the past, but still fail to reach desirable effect.
Summary of the invention
The utility model is exactly for the problems referred to above, provides a kind of spiral automatic correcting stone roller possessing cleaning, pooling feature.
For achieving the above object, the utility model adopts following technical scheme, and the utility model comprises three, left, center, right spiral cradle roll, and the screw thread of left side and right side spiral cradle roll is respectively one-way spiral structure, and one of them is dextrorotation, and another is left-handed; Intermediate conveyor screw carrying roller is bidirectional screw structure, namely with its line of centers for boundary, half is dextrorotation, and second half is left-handed; The helix line number of three spiral cradle rolls in described left, center, right is two-wire, three lines or four lines; Described spiral cradle roll comprises roller skin, roller carrier shaft, bearing seat, bearing, seal ring and end cap, described bearing seat is located at described roller intracutaneous, described bearing seat and described roller skin interference fit, described bearing is located in described bearing seat, described bearing and described bearing seat interference fit, described bearing and described roller carrier shaft interference fit, described seal ring and described bearing seat interference fit, described seal ring and described roller carrier shaft interference fit, described end cap is located in described bearing seat, it is outside that described end cap is located at described seal ring, described end cap and described roller carrier shaft interference fit; Described roller skin adopts rubber plastic roller skin, and rubber plastic roller skin is threaded.
As a kind of preferred version, thread groove portion described in the utility model center bottom is provided with arc groove.
As another kind of preferred version, lead angle described in the utility model is 12 ° ~ 23 °.
As another kind of preferred version, left side described in the utility model spiral cradle roll and right side spiral cradle roll are with the little tapering of outer imperial palace.
Secondly, rubber plastic roller skin described in the utility model is polyurethane roller skin.
In addition, left side described in the utility model spiral cradle roll and right side spiral cradle roll have the radian corresponding with transport tape concaved along its length.
The utility model beneficial effect.
The utility model adopts three, left, center, right spiral cradle roll to match, and makes the load-transfer device of operation produce stronger horizontal reset force, efficiently solves belt deflection problem.Because the roller skin of carrying roller adopts antistatic, fire-retardant rubber plastic roller skin, decrease the wearing and tearing of load-transfer device, cushion between load-transfer device and carrying roller because of impact that material and external factor bring, extend the service life of load-transfer device, the attachment at the conveyer belt back side can also be cleaned, effectively improve transport capacity.The utility model centering capacity is strong, is the spiral automatic correcting stone roller integrating cleaning, buffering, correction.
Be respectively one-way spiral structure with the screw thread of right side spiral cradle roll on the left of the utility model, one of them is dextrorotation, and another is left-handed, and the rotation direction of screw thread is different, and the transverse force giving load-transfer device so all points to center.
The utility model is rational in infrastructure, safe and reliable, resistance to abrasion is strong, quality is light, can effectively reduce productive costs, improves the safety factor of belt conveyer, ensures the safe and reliable operation of belt conveyer.
