Description
Technical field
The utility model relates to a kind of three fulcrums heavy duty deviation regulating idler, belongs to the auxiliary device of belt conveyer.
Background technology
As everyone knows, during the belt conveyer operation, load-transfer device may be owing to the pulling force deficiency, and material is eccentric to be piled up, stand stretch, the Idler bearing defective, the zero portion in the belt conveyer installs and misaligns, conveying band joint is crooked, and the unequal reason of load-transfer device tension distribution causes belt deflection.Because of the belt deflection scope little, now adopt the flute profile aligning carrier roller to adjust automatically usually, its principle of work as depicted in figs. 1 and 2, entablatrance in activity has three rollers capped edge roller A and the B vertical with two, entablatrance is bearing on the cross sill by center shaft, and can be centered by center shaft, cw or rotate counterclockwise in certain angular range.When belt deflection, belt centerline O ＇ O ＇ is not overlapping with conveyer line of centers OO, when belt deflection is a certain amount of, load-transfer device is run into the capped edge roller of a certain side, load-transfer device is imposed positive pressure N to capped edge roller and friction force Nf(f is friction coefficient), the exercising result of these two power makes entablatrance rotate counterclockwise the β angle around center shaft, load-transfer device is given three power F that roller is consistent with sense of motion, F can be decomposed into and make roller around the power FT of center shaft rotation and make the axially movable power Fa of roller, the location of entablatrance pair of rollers can not move axially roller, thereby the roller effect impels load-transfer device to reset for the counter-force of load-transfer device.
The flute profile aligning carrier roller has following shortcoming:
(1) gives the counter-force of load-transfer device too little, be FTtan β.Because the numerical value of the running resistance FT of carrying roller is little, rotational angle β about 10 °, so give the counter-force of load-transfer device limited, the tuningout DeGrain;
(2) in case after load-transfer device moves to the center, A just disengages with capped edge roller, positive pressure N and friction force Nf have not existed, there is not other power that entablatrance is resetted, if cause that the interim factor of sideslip disappears this moment, load-transfer device will continue to capped edge roller B one side shifting under the counter-force effect of Fa so, equal Fa until resistance.If center shaft rotates the correction effect that just no longer includes of blocking, if Fa is excessive, at this moment load-transfer device will move to capped edge roller A direction under the effect of another Fa again, begin a new circulation, thereby form unsettled " serpentine locomotion ", the serpentine locomotion of load-transfer device increases resistance of motion, carries the wearing and tearing of band edge glue to accelerate;
(3) because the supporting part in groove (putting down) the shape aligning carrier roller is that entablatrance, roller and capped edge roller etc. are bearing on the cross sill by center shaft, so belong to some supporting, when the eccentric accumulation of material, form the center shaft serious wear easily, it is dumb that center shaft is rotated, thereby do not have the correction effect.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of three fulcrums heavy duty deviation regulating idler, carrying roller when being used for Direction Deviation in Belt Conveyer is adjusted automatically, this three fulcrum heavy duty deviation regulating idler solves that single fulcrum aligning both-end support force is little, the shortcoming of mutability, tuningout weak effect, and the tuningout effect is fast, effective.
For overcoming the above problems, concrete technical scheme of the present utility model is as follows: comprise roller, entablatrance, cross sill and mobile supporting seat, its middle roller is connected with entablatrance, the center of entablatrance and cross sill is rotationally connected, the two ends of entablatrance are respectively equipped with supporting rollern, the cross sill two ends are respectively equipped with the adjustment supporting plate, supporting rollern serves as that axle rotates at the adjustment supporting plate with the lower and upper cross-member center, mobile supporting seat is provided with bar-turning mechanism, the upper end of bar-turning mechanism is provided with the flap roller, the lower end of bar-turning mechanism connects connecting rod pulling mechanism, and the other end of connecting rod pulling mechanism links to each other with entablatrance, and mobile supporting seat is fixed on the travelling apron middle frame.
Described three fulcrums heavy duty deviation regulating idler entablatrance be opening greater than the flute profile of bottom, its upper roller is formed flute profile and entablatrance flexible connection by 3.
Described three fulcrums heavy duty deviation regulating idler entablatrance is flat shape structure, and its upper roller is formed flat shape by 1, and flexibly connects with entablatrance.
This three fulcrums heavy duty deviation regulating idler adopts connecting rod pulling structure and bar-turning mechanism to form the connecting rod adjusting deviation device, and bilateral symmetry designs two groups of supports centered by the entablatrance center shaft, thereby solve when the eccentric accumulation of material, the center shaft serious wear, center shaft rotates dumb, and the tuningout effect is undesirable etc.Adopt the connecting rod adjusting deviation device, during sideslip, regulating roller is under the promotion of belt edges, and is outwards mobile, and by the rotation of connecting rod pulling entablatrance, the entablatrance rotational angle is big, and the tuningout torque ratio not tuningout mode with connecting rod is big by 10%.
