Abstract
An upper centering idler of conveyor for correcting strap running deviation of belt type conveyor comprises a base, an idler stand, an idler and a conveying strap. The center of the idler stand is connected with the base by a rotary table and the left and right sides of the idler are connected with the base by movable struts. The idlers consist of a middle idler and two side idlers at left and right sides. The left and right sides of the conveying strap on the idler are arranged with tapered rams respectively with clearances, which are contacted and connected with the edge of the conveying strap. The tapered rams are provided on and integrated with an outer ring stand which is connected with the idler stand by an axle pin. Below the outer ring stand is provided with a movable axis with its outer end connected with a spring and arranged inside the movable axis cover which is fixed on the ring-shaped stand. The end faces of the left and right side idlers are provided with a boss terminal respectively. The utility model has advantages of simple structure, few parts, good automatic deviation correcting effect, reduced cost and prolonged service life.
Description
Technical field
The utility model relates to the conveying arrangement technical field, especially relates to the self-centering idler device in the conveyer transmission device.
Background technology
Belt conveyer is typically equipped with aligning carrier roller for correcting belt deviation, and existing at present multiple aligning carrier roller is in order to realize the correction problem of belt operation; These aligning carrier roller structures are mostly complicated, and interoperation with it such as connecting rod mechanism need be arranged, because parts are many, the probability of damage is also big, influences service life.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiency of prior art, and aligning carrier roller on a kind of simple in structure, parts are few, automatic deviation correction is effective conveyer is provided.
For achieving the above object, the technical solution of the utility model is such: aligning carrier roller on a kind of conveyer comprises the roller rack on base, the base and is installed in carrying roller and belt conveyor on the roller rack; Said roller rack middle part is supported connection with it by the rotating disk that is installed on the base, and the right and left is connected on the base by movable pillar; Said carrying roller is by the middle idler roller of the level attitude that mediates and upwards become the left and right side roller at 35 degree angles to constitute with horizontal direction, taper retaining roller is respectively arranged on limit, the left and right two ends of belt conveyor on carrying roller respectively with a gap, this taper retaining roller can contact connection with the belt conveyor edge, taper retaining roller is installed on the outer ring support, and fuse, outer ring support connects with roller rack by pivot pin; Outer ring support bottom is provided with a movable axis, and inwardly over against a left side or right carrying roller end face, the movable axis outer end connects a spring to this movable axis, and places in the movable axis case, and the movable axis case is fixed on the ring support; On a left side, on the right carrying roller end face boss terminal is set respectively, when the belt conveyor sideslip, a left or right side belt outwards pushes taper retaining roller and rotates an angle along pivot pin, make movable axis inwardly stretch out roller rack, prop up this boss terminal, stop this side carrying roller to rotate, the relative motion of this side belt and carrying roller changes slip into by rolling, friction force increases rapidly, because the increase of this side forward shear force, belt drags the angle that carrying roller reverses sideslip, even the same angle of sideslip is rotated in the complete machine adjustment, belt conveyor is got back to the operation of centering position, and taper this moment retaining roller resets under the spring force effect.
Owing to adopted technique scheme, aligning carrier roller on a kind of conveyer of the present utility model, have simple in structure, parts are few, the automatic deviation correction good effectiveness, leather has removed the former complicated parts such as connecting rod mechanism that need, and can reduce cost, increases service life.
