Abstract
The utility model relates to coal processing machinery, in particular relates to a bucket chain stopper of a bucket type lifter, and relates to a side plate and a bucket chain. The side plate is positioned on one side of the bucket chain; a climbing trace of the bucket chain is a slope; a fixing seat is fixedly connected to the side plate; a rotating shaft is arranged on the fixing seat; and a stopping claw capable of freely rotating is connected to the rotating shaft and leans against the inclined bucket chain under the gravity. The bucket chain stopper is simple in design, is practical, is easy to manufacture and is low in cost; the bucket chain stopper can be used for the bucket chain type lifter and can be applied to drawing of various bucket chains; due to inclination, protection of equipment running in an opposite direction is not allowed; popularization is facilitated; and the bucket chain stopper has a wide market.
Description
Technical field
The utility model relates to Coal dressing machinery, is specially bucket elevator, is mainly used in coal preparation plant and coordinates jigging machine to selecting rear product lifting and the dehydration of (comprising middle coal and spoil).
Background technology
Bucket elevator, in heavy service, sometimes there will be unavoidably and hinders for some reason the heavy load parking, and even breaking pin, at this moment will cause the phenomenon of inverted running that (being commonly called as " sentencing the accuser to the punishment facing the person he falsely accused ") occurs.Sentence the accuser to the punishment facing the person he falsely accused between the material that can make bucket and bottom not withdraw and produce and clash into, very easily cause the distortion of gig bucket, when serious, can make bucket damage can't use; After long-time the use, the bearing pin wearing and tearing are excessive, easily produce chain breaking problem, and after chain rupture, the bucket chain assembly pours in the afterbody casing and is stuck, and causes replacing, maintenance difficult; These problems are coal preparation plant's coal separation workshop hidden danger and a difficult problem always.
The utility model content
Prevent that for reaching the purpose of gushing under antikinesis and chain rupture from appearring in existing bucket chain gig, the utility model is improved bucket elevator, increases by a bucket chain holdback.
The technical solution of the utility model is: bucket elevator bucket chain holdback, relate to side plate, bucket chain, side plate is positioned at a side of bucket chain, the bucket chain track that climbs is dip plane, be fixedly connected with out permanent seat on side plate, one rotating shaft is set on permanent seat, connects the check pawl come from by rotating in rotating shaft, the check pawl rides against on the bucket chain of inclination by its deadweight.
The peripheral limited location baffle plate of described check radix unguis section is fixed on side plate.
Due to bucket, with together with bucket chain is close to, and move with the motion of bucket chain.The carrier bar of bucket chain by sleeve, bearing pin is a section is linked togather, and by great wheel, is driven, and bucket is hoisted by low strap, reaches the purpose of transported material.And the non-return device of our design, as figure is comprised of check pawl, rotating shaft, permanent seat, baffle plate etc.When gig normally moves, the check pawl is driven upwards and swings by sleeve, under the effect of self gravitation, to whereabouts, is driven upwards and swings by next root sleeve again, and so circulation, do not affect the normal operation of equipment; When if inverted running and chain rupture appear in gig, the check pawl can insert between bucket chain it is moved downward with bucket chain together, but slideway blocks the check pawl, makes it no longer to lower swing, finally makes the whole bucket chain can not inverted running.In several seconds at initial stage of the bucket chain inverted running of bucket elevator, its rate of onset is very slow, therefore the check pawl blocks the suffered impulsive force of bucket chain little.
This device simplicity of design practicality, make easily, with low cost, can not only be for the bucket chain bucket elevator, and can apply to various bucket chains tractions and be in tilted layout do not allow the equipment protection of inverted running, easily promote extensive market.
The accompanying drawing explanation
Fig. 1 is side-looking structural representation of the present utility model;
Fig. 2 is plan structure schematic diagram of the present utility model.
In figure, 1. rotating shaft, 2. check pawl, 3. side plate, 4. bucket chain, 5. permanent seat, 6. baffle plate.
The specific embodiment
Bucket elevator bucket chain holdback, relate to side plate 3, bucket chain 4, side plate 3 is positioned at a side of bucket chain 4, bucket chain 4 track that climbs is dip plane, be fixedly connected with out permanent seat 5 on side plate 3, one rotating shaft 1 is set on permanent seat 5, connects the check pawl 2 come from by rotating in rotating shaft 1, check pawl 2 rides against on the bucket chain of inclination by its deadweight.The peripheral limited location baffle plate 6 of described check pawl 2 roots is fixed on side plate 3.
Claims (2)
1. bucket elevator bucket chain holdback, relate to side plate, bucket chain, side plate is positioned at a side of bucket chain, the bucket chain track that climbs is dip plane, it is characterized in that being fixedly connected with out permanent seat on side plate, one rotating shaft is set on permanent seat, connects the check pawl come from by rotating in rotating shaft, the check pawl rides against on the bucket chain of inclination by its deadweight.
2. bucket elevator bucket chain holdback as claimed in claim 1, is characterized in that being fixed on side plate at the peripheral limited location baffle plate of described check radix unguis section.
