Abstract

The utility model discloses a chain traction rubber belt conveyor which is used for conveying bulk materials (such as coal). The chain traction rubber belt conveyor is characterized in that the chain traction rubber belt conveyor changes the friction transmission of an ordinary belt conveyor into chain transmission, which reduces the strength requirement of a rubber belt and enlarges the conveying length of a single machine, and the chain traction rubber belt conveyor can safely brakes in time when deceleration or emergency stop are needed during materials are conveyed downward. A metal partition 11 which is used for preventing the materials from gliding downward is arranged on the rubber belt, which enables the rake angle beta of the chain traction rubber belt conveyor to be enlarged to 30 DEG or so. The utility model is particularly suitable for the occasions of the long-distance conveyance of bulk materials downwards or upwards along a big rake angle.

Description

Chain belt conveyor

The utility model is a kind of travelling apron that the edge tilts to transport up or down fragmentary material (as coal or ore), uses chain traction that is used for.The normal tape conveyer that is widely used in mine, factory, warehouse, harbour at present all be with an electrodeless adhesive tape as load-carrying unit, drive adhesive tape by friction force between drive roll and the adhesive tape, thus adhesive tape be load-carrying unit be again driver element.This principle of work makes the normal tape conveyer have following shortcoming:

1. when carrying angle of inclination beta (Fig. 1) big, material is understood natural downslide, and when therefore upwards transporting coal, the inclination angle can not be greater than 18 °.

2. be subjected to the restriction of tape tensile strength, the length of unit can not be oversize, generally is no more than 1000m in the mine.

3. when transporting material downwards and needing reduction of speed or sudden stop,, skid in order not make adhesive tape and cylinder because adhesive tape is a frictional transmission, must limit the value of deceleration/decel, can not be too big, thus be difficult in time, braking safely, therefore limited the inclination angle and the length of downward transportation.

The purpose of the utility model travelling apron is to solve along high spud angle, up or down the problem of long-distance transportation material.

The existing both at home and abroad technology that solves this problem has:

1. belt conveyer with wire core.Owing to make core with steel rope, strengthened the intensity of adhesive tape, so transportation range can be very long, but can not solve along the slip of high spud angle transported material and the timely braking problem of transporting downwards.

2. with surperficial figuratum adhesive tape, strengthened the adhesive ability between adhesive tape and the material, made the transportation inclination angle can be increased to 25 °, slightly improved than normal tape conveyer, but increased adhesive tape thickness and driving drum diameter.When high-power multiple-roll transmission, excessive for fear of specific pressure because the decorative pattern face will contact with head roll, tension force that must the restriction adhesive tape can not be excessive, also just limited the increase of transmission power.Do not solve long-distance transportation and the transportation downwards problem of braking in time.

3. be pressed on the material and the material uniform movement with another electrodeless adhesive tape, the clamping material does not make downslide, and promptly so-called double belt is carried, and has realized the high spud angle transportation, but complex structure, it is big to take up space, the price height, and also length can not be very big.

Feature of the present utility model is:

1. the frictional transmission with the normal tape conveyer changes the chain engaged transmission into, and making adhesive tape no longer is driver element, and therefore the requirement of strength to adhesive tape greatly reduces.Because the intensity of chain is very big, add along conveyor lengths can (50m～250m) sets up intermediate gearing arbitrarily, thereby the laying length of conveyer can be increased greatly (surpassing 1000m) every certain intervals.In addition, owing to adopted engaged transmission, the glancing impact adhesive tape does not have slide relative, so can adopt bigger deceleration value, realizes easily in time braking or slowing down, and has solved the safety problem of downward transportation.

2. a full dividing plate that belongs to is set on adhesive tape at a certain distance, stops the downslide of material, the inclination angle of upwards transporting coal can reach 30 °.

The principle schematic of the utility model chain haulage travelling apron as shown in Figure 1, β represents the inclination angle of conveyer; 1 and 2 is unloading and track adjusting wheels of frame head and tail, also can the double as driving wheel; 3 are the pop-up chain cable fairlead; 7 for pressing down chain cable fairlead; 4 is the crawler type chain gearing, can be by transportation lengths and transportation-production rate one or more (only having drawn two among the figure) need be set in the middle of the travelling apron; 5 is the caterpillar block of crawler type chain gearing 4; 6 is the driving wheel of crawler type chain gearing 4.Have recessed chain (see figure 5) on caterpillar block 5 surfaces, electrodeless tow chain 9 meshes in groove, move with caterpillar block, and carrying adhesive tape 8 just is fixed on the tow chain 9, thereby has realized the motion of cargo.

For fear of the overtension of following strand conveyer belt, can on following strand chain, also install chain gearing 4 one or more, help to drive following burst of chain (see figure 1).

In order to reduce the running noise between caterpillar block 5 and the electrodeless tow chain 9, can on mating surface, add one deck high strength anti rubber milling or plastic gasket (seeing 18 among Fig. 5).Because electrodeless chain is a step traction, its tension force changes with the distance between two crawler type chain gearings 4, and irrelevant with the total length of travelling apron, so not high to the requirement of strength of adhesive tape.

Fig. 5 is the structure diagram of caterpillar block 4, and 17 is steel part among the figure, and 18 is high strength anti rubber milling or plastic gasket.

Embodiment of the present utility model as shown in Figures 2 and 3 when high spud angle transports.13 is the tissue layer up and down of adhesive tape, and 11 is anti-skidding dividing plate, and 12 is last idler pulley, and 9 is electrodeless tow chain, adopts round-link chain herein, flexible good because of its intensity height, makes easily, and 10 is connecting pin, and round-link chain 9 and dividing plate 11 are fixed together.Two adjacent clapboard spacings can be decided to be 1m to 1.4m.In adhesive tape, in conjunction with closely, but complex process, cost is higher, the inconvenience maintenance with dividing plate 11 hot pressings for this structural requirement.

Fig. 3 is another embodiment, and 8 is common light duty adhesive tape or old adhesive tape, links to each other with dividing plate 11 with rivet or screw 16 by pressing plate 15, and other structure is then identical with Fig. 2.This structure is easy to make and maintenance, and cost is low.

Fig. 4 is the cross-sectional view of following strand conveyer belt, and 14 are following idler pulley among the figure, and other original paper is identical with Fig. 2.

Other parts of this travelling apron, as tightening device, control monitor unit, frames etc. can be identical with the normal tape conveyer.

In the transportation of short range (less than 200m) high spud angle, the utility model travelling apron can be cancelled middle crawler type chain gearing 4, and comes transmission by the sprocket wheel of head, greatly simplified structure.

As seen travelling apron of the present utility model can solve high spud angle, long distance and downward transported material problem, does not need complexity, premium-quality manufacturing technology, and manufacturing cost is also lower.Since cancelled the frictional transmission of adhesive tape, can be because of the unexpected frictional heat presence of fire of adhesive tape, and this uses the colliery is very much important.

Because adhesive tape system uses chain-driving, so the tape speed of this machine will be lower than the travelling apron of frictional transmission, is advisable to be no more than 2m/s, has reduced transportation volume, this is a disadvantage.
