Abstract

The utility model relates to a belt-broken protector, which utilizes the frictional force generated by the gliding of the rubber belt along the incline direction as the driving source to accomplish the multiple-point brake on the rubber belt to prevent the great economic loss caused the broken rubber belt after a rubber belt is broken. The belt-broken protector can be also matched with the existing vertical roll to prevent the rubber belt from being bonded. The belt-broken protector is composed of a friction wheel, a driving member, a bracket and a brake block, etc. The belt can be broken at any position along the line of a conveying machine, the belt-broken protector can efficiently and reliably brake the rubber belt on a heavy-load section. The belt-broken protector is chiefly used for an uphill/downhill rubber belt conveyor of a mine, and can be also used for a ground rubber belt conveyor for conveying granular materials with a big inclination angle in a long distance.

Description

Belt-broken protector

The utility model relates to the technical field of mine travelling apron broken belt protector aspect.

Along with the continuous development of mine machineryization, the travelling apron that use on the upper and lower mountain of mine increases day by day, but also constantly develops towards the direction of growing distance, large conveying quantity.In this case, if the adhesive tape fracture takes place, usually be one of thing of headache the most during mine is produced, it not only makes adhesive tape be slipped to the bottom of belt feeder with mineral, stop up the tunnel, cause and bury head, damage electromechanical appliance, the difficulty on cleaning and the handling failure, and the time that continues is long, what relate to is wide, and the influence that the ordinary production of mine is constituted is big, and the economic loss that causes is also extremely serious.At present; in the approach aspect the solution broken belt protector two classes are arranged roughly: a class what is called is preventative; based on software administration; just with daily management; be maintained as the work means; pinpoint the problems; eliminate its hidden danger immediately; reach the purpose that prevents trouble before it happens; this also is a method in common comparatively at present; but it is, then powerless to the problem that tape splice inside exists because the limitation that this practice is brought only is applicable to the inspection and the prevention of tape splice and adhesive tape outward appearance; therefore the broken belt protector problem still can not get the solution of property actually, but also cost great amount of manpower and material resources.The so-called non-expansion type of second class when occurring the broken belt situation exactly, can be arrested upper and lower adhesive tape rapidly, resumes production with speed as soon as possible, makes every effort to not produce loss or loss is dropped to bottom line.Domestic also had certain research in this respect; arrange the belt break protection device of full sectional form as single-point; this mode complex structure, the cost height, and with the randomness of broken belt point; often because of broken belt point below arresting that protection puts; lost its due function, promptly allowed to arrest, also Chang Yin is too far away from broken belt point; still need the cleaning of long period, just can resume production.

At above-mentioned situation, the purpose of this utility model is exactly the constructional feature according to the adhesive tape transportation; design a kind of simple structure; with low cost, can be convenient on adhesive tape is along the line, arrange several or a plurality of, the adhesive tape both sides are carried out the belt break protection device of local section braking pattern.

Of the present utility modelly to the effect that arrange a cylindrical friction wheel and respectively arrange a cylinder friction eccentric wheel in its both sides in mid-stent, be provided with flexible transmission device between cylindrical friction wheel and cylinder friction eccentric wheel, this external both sides cylinder eccentric top that rubs also is equipped with stepping brake block mechanism and braking force setting mechanism.

Can see thus; the utility model has overcome the single-point layout, section is braked the shortcoming of the broken belt protector aspect of pattern entirely; because of the variation of broken belt point randomness, it can both not brake heavy duty section adhesive tape rapidly and effectively, prevents the heavy economic losses that causes therefrom.In addition, it also can match with anti-inclined to one side edger roll, stops the bag of adhesive tape handsome, and where necessary, it also can be made scotch-tape device and use.Be mainly used on the travelling apron that uses on the upper and lower mountain of mine, also can be used for long distance, high spud angle, transport on the ground travelling apron of granular material.

Now accompanying drawing is made brief description:

The front view of Fig. 1 belt breakage protector

Now detail illustrates its structural principle and embodiment in conjunction with the accompanying drawings.As shown in drawings, bearing ［ 20 ］ is housed on support ［ 24 ］, with and on also be welded with ear ［ 2 ］ and block ［ 3 ］ in succession.In middle part cylindrical friction wheel ［ 17 ］, the eccentric friction wheel ［ 13 ］ in both sides, ［ 23 ］ bearing seat is housed all, to bulbus cordis antifriction-bearing box ［ 19 ］, they are stuck on the bearing ［ 20 ］ by axle ［ 18 ］, ［ 22 ］ respectively, two eccentric friction wheel both sides are respectively equipped with bearing pin ［ 21 ］, ［ 12 ］ in addition, and intermediate friction wheel both sides also are provided with bearing pin ［ 16 ］; Pulley ［ 15 ］ in the flexible transmission device is arranged, flexible tape ［ 14 ］ between the eccentric friction wheel ［ 13 ］ in the both sides of middle part friction wheel ［ 17 ］, ［ 23 ］; Respectively there are fixed block ［ 5 ］, brake shoe ［ 8 ］, fire retardant glue face ［ 11 ］, connecting bolt ［ 7 ］, trimming screw ［ 6 ］ in top in two friction eccentric wheel ［ 13 ］, ［ 23 ］, and brake shoe mechanism and the braking force setting mechanism formed with the bearing cap shim ［ 4 ］ between spiral bonded assembly faying face between fixed block ［ 5 ］ and the support ［ 24 ］.

The utility model mainly is installed on the downside at maximum defluxion place between two carrying rollers, should choose the thickness of pad ［ 4 ］ during installation according to adhesive tape thickness, then by connecting bolt ［ 7 ］, adjust spiral ［ 6 ］ braking force of having adjusted, when the belt feeder normal operation, adhesive tape ［ 9 ］ and friction wheel ［ 13 ］, ［ 23 ］, brake shoe ［ 8 ］ does not all contact, friction eccentric wheel ［ 13 ］, ［ 23 ］, intermediate friction wheel ［ 17 ］ is respectively by bearing pin ［ 21 ］, ［ 16 ］ be bearing on the bearing ［ 20 ］, in case generation broken belt, the adhesive tape sag increases, certainly will take and drop on three friction wheels, because the relation at adhesive tape flute profile angle, middle part cylindrical friction wheel ［ 17 ］ is than the both sides eccentric wheel ［ 13 ］ that rubs, ［ 23 ］ positive pressure that bears is big, therefore under adhesive tape downslide effect of inertia, intermediate friction wheel ［ 17 ］ has produced the friction force distance of major part, by cone pulley ［ 15 ］, flexible tape ［ 14 ］ is delivered to both sides friction eccentric wheel ［ 13 ］, ［ 23 ］ on, with they self friction force under combined action, just three friction wheels are rotated simultaneously with the downslide of adhesive tape, feasible friction eccentric wheel ［ 13 ］, ［ 23 ］ more and more littler with the gap of brake shoe ［ 8 ］, when touching brake shoe ［ 8 ］, adhesive tape has just been produced friction brake force, this power is with eccentric wheel ［ 13 ］, ［ 23 ］ increase of corner and increasing, when the bearing pin on the eccentric wheel ［ 12 ］ is bearing in block ［ 3 ］ on the support, braking force has just reached the value of being adjusted, adhesive tape just constantly is decelerated under this constant braking force effect, till being braked fully.
