Description

Tubular belt conveyer

The present invention relates to a kind of tubular belt conveyer, wherein most endless apron is rolled into tubulose, deposits the material that is transferred in the tubulose band, reaches the purpose of continuous conveying.

In traditional tubular belt conveyer, the shape of a plurality of support belt keeps frame with fixing spacing setting.

When this tubular belt conveyer uses in colder area,, so at low temperatures, be with hardening possibly because the tubulose band is made by rubber usually.

The load-transfer device of hardening needs very big power just can roll, and if this power elimination, its can turn back to flat state very soon.

If but made load-transfer device keep long time of tubulose, even if power is eliminated so, it could not turn back to flat state yet.

Similarly, have when this that to keep the conventional conveyor of frame to be used in the shape of constant spacing setting colder when regional, around the shape of tubulose band keep frame the beginning part of preceding stand in channel and backward channel will with very big antagonistic force, thereby caused reducing the service life that shape keeps frame.In addition, keep between the frame two adjacent shapes, the expansion of load-transfer device or open can cause running resistance to become big.

Furtherly, when the load-transfer device of hardening during by segmental arc, shape keep frame will with very big antagonistic force, cause increasing running resistance, finally make the frame fracture damage.

In light thermally district, if make shape keep frame to have long spacing, will make the load-transfer device distortion become ellipse or distorted shape at the arch section of conveyer, same, also increased running resistance.

Only need seldom power to come the tubulose of retainer belt except other outer parts of initial portion and arch section.What therefore, the employing of the shape of tubular conveyor belt maintenance frame was fixing is uneconomic at interval.

The purpose of this invention is to provide a kind of can reducing and be added in the tubular belt conveyer that shape keeps the antagonistic force on the frame, thereby prevent its damage or fracture by band application.

Another object of the present invention provides a kind ofly has high service life and the low tubular belt conveyer of cost on making.

According to the present invention, the shape of tubular belt conveyer keeps frame partly little than the interval of other parts in the beginning of preceding stand in channel and backward channel, and therefore band can be rolled easily.

In addition, keep other parts of gap ratio of frame little in the shape of arch section, thereby reduce antagonistic force and running resistance.

Objects and advantages of the present invention become more clear by following to preferred embodiment and with reference to describing of accompanying drawing.

Fig. 1 and Fig. 2 are respectively according to the rear portion of tubular belt conveyer of the present invention and anterior diagram.The preceding flush end of endless apron 1 and back flush end are wound on respectively on front end roller 2 and the rear end roller 3, are driven by the actuating device (not shown) with 1 direction of arrow shown in the figure.

Near roller 2 and 3, have with 1 first roll frame 4, the second and roll frame 5, the first shapes and keep the frame 6 and second shape to keep frame 7.

Fig. 3 has represented the arch section with 1 preceding stand in channel 1a.Shape at segmental arc C keeps the spacing of the spacing of frame 6 less than straight line portion D.

As shown in Figure 4, in first front portion of rolling frame 4, a horizontal rolling-up roll 8 and a pair of outward-dipping roller 8a are arranged, second rolls the front portion of frame 5, has a horizontal rolling-up roll 8 to extend upward and the rolling-up roll 8a vertical with roller 8 with a pair of.

Two rear portion and its front portions of rolling frame 4 and 5 are symmetrical, so do not illustrate at this.

Fig. 5 is along the section-drawing of A-A line among Fig. 1.In Fig. 5, form a pair of circular hole 10 on the stay bearing plate 9 of rectangle first shape maintenance frame 6, a plurality of shape holding rollers 11 are arranged on the circumference in hole 10, form a circle, and this circular diameter is less than the diameter in hole 10.

Fig. 6 be among Fig. 1 along the section-drawing of B-B line, in Fig. 6, second shape keeps frame 7 by horizontally separated, pair of holes 10 and a plurality of shape holding roller 11 are arranged on the stay bearing plate 12.

As illustrated in fig. 1 and 2, first shape keeps frame 6 to roll between the frame 5 by fixing interval setting at two second.The rear end of tubulose conveyer and first shape keep second shape between the frame 6 keep on the frame 7 hole 10 with forwardly on first shape that forms keep frame 6 hole 10 on the same longitudinal axis, keep the hole 10 on the frame 7 to keep the hole 10 of frame 6 on the same longitudinal axis in second shape of the front end of conveyer with first shape that is forming on the rear portion.

In Fig. 4, the preceding stand in channel 1a of load-transfer device 1 is opened into flat-shaped by the bottom time, and when rolling frame 4 by first, is rolled into tubulose by rolling-up roll 8.

Then, the feeding hopper 13 of the material that is transferred above being located at rear end roller 3 sent into preceding stand in channel 1a.When with 1 by be arranged on first shape keep frame 6 on hole 10 time, roll by rolling-up roll 8, forms a tubulose that encases convey materials, and by shape maintenance frame 6 and 7.

After current stand in channel 1a rolled frame 5 and 4 by second and first, preceding stand in channel 1a was opened, thereby made the material that is transferred fall into receptor 15 around front end roller 2.

After backward channel 1b walks around front end roller 2, rolled-up equally, again by the hole 10 on the bottom that is arranged on shape maintenance frame 6 and 7, by rear end roller 3.

When this tubulose conveyer was used in cryogenic region, the load-transfer device 1 that flattens at front end roller 2 and rear end roller 3 was rolled the rolling-up roll 8 on frame 4 and 5 and is kept the shape holding roller 11 of frame 6 to be rolled into tubulose in first shape first and second.When load-transfer device 1 left shape holding roller 11, its diameter had the trend of increase, and when being with 1 by behind the shape holding roller 11, its diameter is forced to shrink, and this effect repeats.

According to tubular belt conveyer of the present invention, beginning part at preceding stand in channel and backward channel, second shape keeps frame 7 to be arranged between first shape maintenance frame 6, shape with shape holding roller 11 keeps frame 6 and 7 to separate with less spacing, therefore, the amount that band outwards increases is very little, and also is little in the running resistance of beginning part.After load-transfer device passed through along the beginning part, the trend of hardening and increase was reduced, and therefore, load-transfer device itself can keep tubulose, when keeping frame 6 by further shape, very little running resistance is only arranged.

In Fig. 3, shape keeps frame 6 suffered antagonistic forces to become big on the stand in channel 1a before arc, and therefore, its running resistance increases than the resistance of straight section D.

Yet, according to tubular belt conveyer of the present invention, keep the weak point of the spacing of frame than other parts in the shape of segmental arc C, therefore, tubular conveyor belt 1 can be guided glossily.
