The utility model aims to provide a tensioner adapted to bidirectionally transport and move a conveyer belt to meet the operational requirement of efficient tensional control of the conveyer belt in a condition of frequent change in transport and movement direction, as well as the adjustment of mounting angle of the belt pulley. The technical proposal is that a gravity traction device is additionally arranged on a screw-spindle tension mechanism and comprises a sliding seat, a traction steel wire, a counterweight and a pulley; wherein the sliding seat loads the screw of the screw-spindle tension mechanism, one end of the traction steel wire is connected with the sliding seat and the other end thereof is enwound around the pulley and then connected with the counterweight, and the sliding seat can slide along a supporter. The utility model can ensure the upper ring of the conveyer belt in tension state all along and has the advantages of simple structure, reliable performance, and suitability for conveyer belts with frequent change in transport and movement direction in the sintering mining production lines.
Description
Technical field
The utility model relates to the tightening device of load-transfer device, especially can positive and negative conveying and the tightening device of load-transfer device movably.
Background technology
In the conveying flow process of material, normal use can positive and negative conveying and the conveyer belt apparatus that can move forward and backward simultaneously.During the running of load-transfer device forward, going up of load-transfer device closed loop encircles limit in tension, normally convey materials; When the reverse running of load-transfer device, the ring limit of going up of load-transfer device closed loop is in relaxed state, this moment is if feeding coal is inhomogeneous, just often occurring encircling the limit on the material compressing load-transfer device sink it significantly, cause that load-transfer device is stuck on the belt roller or belt pulley phenomenon such as skid, load-transfer device can't normally be moved, influence carrying out in order of technological process, and then influence is produced.In the prior art, the general employing of the tightening device of load-transfer device established setting devices such as leading screw screw at (generally on driven pulley) on the belt pulley, the adjustment seat that has screw is fixed on the bracing frame that conveyer belt apparatus is installed, leading screw then is connected with the bearing seat of belt pulley, the bearing seat at rotating threaded shaft drive pulley two ends is forward and backward when mobile, just can or unclamp the load-transfer device tensioning.Setting device also has a vital function except that being used to adjust the degree of tension of load-transfer device, promptly can adjust the setting angle of belt pulley in just installing and using, thereby adjusts the effective area of contact between belt pulley and the load-transfer device, guarantees the frictional transmission of the two.This setting device is used for can positive and negative conveying and during the load-transfer device of tool locomotive function, because the ring limit of going up of load-transfer device is in tensioning and the lax checker, so need adjust continually, lower when the frequency of adjusting, when pitch time is longer, also can be by manually adjusting by leading screw; If the frequency height of adjusting, when per hour adjusting several times, then can't implement artificial adjustment, can only above ring limit in tension be the degree of tension that load-transfer device is adjusted on the basis, can't overcome this moment to go up when the load-transfer device retrograde rotation is carried to encircle the limit and be in all disadvantages that relaxed state brings.For a long time, this problem is the principal element that influences such load-transfer device normal operation always.
Summary of the invention
Technical matters to be solved of the present utility model provides a kind of positive and negative conveying and tightening device of load-transfer device movably of being used for, load-transfer device can both obtain the requirement of effective tensioning control when this device should satisfy frequent changes conveying, moving direction, and should conveniently adjust the setting angle of belt pulley.
The technical solution of the utility model is:
But a kind of tightening device that is used for the inverse move load-transfer device, it comprises leading screw, screw, nut seat, leading screw one end passes screw, the other end is connected with the bearing seat of load-transfer device middle belt pulley, and its improvement is that it also comprises slide 13, traction steel wire 16, counterweight 17 and pulley, described nut seat 12 is fixed on the slide, slide, pulley are installed on respectively in the support of Pulley shaft bearing, and traction steel wire one end is connected with slide, and other end pile warp pulley is connected with counterweight.
The above-mentioned tightening device that is used for reversible load-transfer device, described pulley quantity is two, and pulley 14 is positioned at the slide tail end, and pulley 15 is positioned at the back upper place of pulley 14.
The utility model adopts the design plan of setting up gravity traction mechanism on former leading screw screw adjusting mechanism, a kind of promptly convenient belt pulley setting angle of adjusting is provided, can carry, make during moving direction the slack-free all the time device in ring limit on the load-transfer device again at frequent changes, go up all disadvantages that the lax influence in ring limit is brought when such load-transfer device reverses for a long time thereby overcome, obtain satisfied improvement effect.The utility model is simple in structure, be easy on existing leading screw screw adjusting mechanism, install and use, have small investment, instant effect, use reliable, adjust advantages such as easy to operate, be suitable for that in manufacturing lines such as sintering, ore dressing frequent changes is carried, use in the conveyer belt apparatus of moving direction.
