Description
Technical field
The utility model relates to a kind of shaped steel stand flat support device in a row, especially a kind of shaped steel flat support device pivoted arm Transmitted chains tensioning mechanism.
Background technique
Stand in a row is a kind of rolling machinery supplementary equipment, its effect be by aligning after rolled piece move on cold saw roller-way, for cold saw is prepared.Namely shaped steel shown in Fig. 1 stand flat support device in a row is a kind of device for being carried out shifting between the operation of stand in a row by steel.Can rolled piece be moved laterally to stand in a row from straightening machine rear mill table, have employed Hui Sidun mechanism principle in device and realize flat lifting transfer, the advantage such as have that screen is fast, span large, location is accurate and noise is little.In carrying rolled piece process, rolled piece is in translation state always, so avoid the galled spots of rolled piece, substantially increases the surface quality of rolled piece.
Shaped steel shown in Fig. 1 stand flat support device in a row, its structure specifically comprises pivoted arm, tray rack 2 is provided with above pivoted arm free end, pivoted arm free end below tray rack 2 is provided with movable sprocket wheel 3, pivoted arm connecting end is provided with fixed chain wheels 7, transmission shaft 5 is provided with in the middle part of fixed chain wheels 7, drive chain 4 is arranged with between movable sprocket wheel 3 and fixed chain wheels 7, also be provided with controlling device 6 below pivoted arm connecting end to be connected with fixed chain wheels 7, above pivoted arm stage casing, be also provided with tensioning mechanism 1.This flat support device have employed Hui Sidun mechanism principle, and during its work, pivoted arm moves in a circle.When transmission shaft 5 driven rotary arm rotates, rolled piece is held up reposefully by bracket 2 and moves horizontally, fixed chain wheels 7 due to be conditioned device 6 fix, so can not rotate around transmission shaft 5, the Chain conveyer speed ratio i=1 of fixed chain wheels and movable sprocket wheel simultaneously, the absolute angular velocities making movable sprocket wheel is zero, this ensures that theres in Hui Sidun lever rotation process, remains vertical position with the bracket of movable sprocket wheel fixed connection.After Hui Sidun mechanism picking-up rolled piece turns over several angle, then rolled piece is placed on another working position, just completes a working stroke.
In above-mentioned existing shaped steel stand flat support device in a row, drive chain is the key part of lead agency running, in order to chain is easy for installation, also in order to the tightness of adjusting chain, on chain side, tensioning mechanism is installed during design, the upper and lower of Idle wheel is regulated by bolt, thus the tightness of adjusting chain.The structure of described tensioning mechanism is see Fig. 2, comprise one vertically to arrange and the Idle wheel 1 be engaged in above drive chain, coaxially be fixedly installed tension wheel shaft 5 in the middle part of Idle wheel 1, tension wheel shaft 5 is arranged with sleeve 4, packing ring 6 and nut 7 successively away from Idle wheel 1 one end; Tension wheel shaft 5 outer sleeve 4 position can slide up and down to be arranged on and also realize fixing by nut 7 and packing ring 6 on pivoted arm 2, pivoted arm 2 directly over sleeve 4 also spins and is provided with adjusting bolt 3, adjusting bolt 3 lower end and sleeve 4 connect and for realizing up-down adjustment.
In this existing tensioning mechanism, because bolt and Idle wheel belong to point cantact.When chain tension, chain produces radial tension power upwards to Idle wheel, forms tilting moment, when this moment is excessive, the Idle wheel of tension wheel shaft will be made at one end upwards to overturn with the active force that bolt is downward.When being turned to a certain degree, packing ring lower end contacts with pivoted arm, thus produces the moment contrary with reverses direction, finally could realize balance.But now Idle wheel is in rollover states, affect tension effects, drive chain even can be caused time serious to come off, flat support device cannot be worked, reduce working life.
Model utility content
For above-mentioned the deficiencies in the prior art, technical problem to be solved in the utility model is: how to provide a kind of compact structure, works smooth and easy, long service life, the shaped steel flat support device pivoted arm Transmitted chains tensioning mechanism of good reliability.
In order to solve the problems of the technologies described above, the utility model have employed following technological scheme:
A kind of shaped steel flat support device pivoted arm Transmitted chains tensioning mechanism, comprise one vertically to arrange and the Idle wheel be engaged in above drive chain, coaxially be fixedly installed tension wheel shaft in the middle part of Idle wheel, tension wheel shaft is arranged with sleeve, packing ring and nut successively away from Idle wheel one end; Tension wheel shaft outer sleeve position can to slide up and down to be arranged on pivoted arm and to realize by nuts and washers fixing, the pivoted arm directly over sleeve also spins and is provided with adjusting bolt, and adjusting bolt lower end and sleeve connect and for realizing up-down adjustment; It is characterized in that, be vertically provided with jack in the middle part of described sleeve top surface, described adjusting bolt lower end is just arranged in jack grafting rotationally.
In the utility model, sleeve upper center is provided with jack, the grafting of adjusting bolt lower end is arranged in jack, like this, when Idle wheel is stressed tumble time, tilting moment passes to bolt by sleeve, and bolt has a reaction force to supporting sleeve, and it is identical to produce a size, the moment that direction is contrary, thus counteract the effect of tilting moment, Idle wheel can not be upwarped.And then ensure that tension effects, ensure that flat support device working stability is smooth and easy, extend working life.
As optimization, described sleeve is the eccentric adjusting sleeve that side, upper end thickeies, and described jack is provided with sleeve upper end thickening place.Can conveniently ensure sleeve bulk strength like this.
As optimization, described sleeve bottom is also vertically provided with tapped hole and adopts the screw of coupling to be fixed on tension wheel shaft through tapped hole.This ensure that and do not produce relative displacement between sleeve and tension wheel shaft, ensure that sleeve is more stable and play a role securely.
As optimization, described Idle wheel inner chamber is installed in rotation on tension wheel shaft by the bearing that two are set up in parallel, and is fixedly connected with in inner chamber outer end and is provided with end casing.Like this, make tensioning mechanism work more reliable and more stable, long service life.
In sum, the utility model has simple and compact for structure, works smooth and easy stable, long service life, the advantages such as good reliability.
