Description

[Detailed description of the invention] [Industrial field of application] The present invention is a rapid transport system suitable for lifting and transporting granular materials such as sand, sieve residue, crushed stone, and sand to a high position in water treatment plants. This relates to an incline belt conveyor.

[Conventional technology]

BACKGROUND ART Conventionally, a chain conveyor with flights as shown in FIG. 5, which is an explanatory view of the main part, has been used to continuously lift and transport sediment generated in, for example, a water treatment plant. In the same figure, sprocket wheel 3
A chain 33 is endlessly rotatably wound between 1 and 32.
A plurality of flights 34 are attached at equal intervals to the trough 35, and are moved within the trough 35 to lift up and carry out the sediment. The chain conveyor with the above configuration has a cover 36
It has advantages such as being able to be sealed tightly, allowing water such as sand to be drained during lifting and transporting, and furthermore, by using a bucket type flight 34, it is possible to transport on a steep slope. However, it has drawbacks such as not being able to be conveyed vertically, having many worn parts, and having a large bending radius, making it difficult to shift from a horizontal state to an inclined state.

As a solution to the above-mentioned drawbacks, there is a corrugated conveyor shown in FIG. In the figure, a driving pulley 41 and a driven pulley 42
A belt 43 is endlessly rotatably wound between the two, and is arranged in, for example, an S-shape via disc rollers 44 and 45. As shown in an enlarged perspective view of the main part in FIG. 7, the belt 43 is provided with corrugations 46 formed in a corrugated manner near both end edges and a transverse strut 47 perpendicular to the running direction of the belt 43. The corrugated conveyor having the above-mentioned structure has the advantage that it is possible to lift and unload in a vertical state, and also that it can prevent the conveyed objects from falling or being scattered during lifting and unloading.

[Problem that the invention attempts to solve]

However, in the corrugated conveyor having the above configuration, since it is necessary to fix the corrugations 46 of a special shape, the structure is not only complicated, but also the conveyed objects may adhere to the surface of the belt 43 or the corrugations 46 and peel off. The problem is that it is difficult. In addition, the shape of the belt 43 must be changed depending on the angle at which it is disposed, and there is also the problem that the deodorizing means becomes relatively large-scale when the conveyed material is sand or sieve residue. ing. Furthermore, since the disc rollers 44 and 45 shown in FIG. 6 are configured to press both ends of the belt 43 at the bent portion,
As shown in FIG. 7, the disk rollers 44, 4
There is also the problem that it is necessary to provide 5 pressing parts, which reduces the effective width of the belt 43 and reduces transportation efficiency.

It is an object of the present invention to solve the problems existing in the above-mentioned prior art and to provide a belt conveyor for steep slopes having a large effective belt width and high conveying capacity.

[Means for solving problems]

In order to solve the above-mentioned problems of the prior art, in the present invention, a flat belt made of a flexible material wound endlessly between a driving pulley and a driven pulley is provided with an outer surface perpendicular to the running direction of the flat belt. A plurality of cross beams made of a rigid material are arranged so as to protrude from the outer surface of the flat belt, a lodging plate made of a flexible material is fixed to the cross beams, and guide rollers are attached to both ends of the cross beams. , side covers made of a rigid material and extending between adjacent crosspieces are provided so as to be rotatable with the respective crosspieces, the side covers shield both end edges of the flat belt, protrude from the inner and outer surfaces of the flat belt, and A technical measure was adopted in which the side cover is formed so as to be in overlapping and sliding contact with another adjacent side cover, and a stopper for preventing the side cover from falling down is provided on the side cover so that it can be freely engaged with and detached from the side cover.

[Effect]

With the above configuration, on the conveyance side, the horizontal rails and the falling plate provided so as to protrude from the outer surface of the flat belt prevent the conveyed object from falling on the flat belt in a steeply inclined state, and the horizontal rails at both ends The side cover provided on the belt allows the transported object to be lifted and transported without being scattered outside the belt. Furthermore, since the crossbars made of a rigid material are provided at right angles to the running direction of the flat belt, it can be expected that the flat belt will run smoothly without deformation even at bends in the running path.

〔Example〕

FIG. 1 is an explanatory diagram of main parts showing an embodiment of the present invention. In the figure, 1 is a casing trough;
An input port 2 and a discharge port 3 are opened at an input place and a discharge place for sand etc., respectively, to form a substantially S-shape via a vertical transport section 1a. A driven pulley 4 is provided near the input port 2 and the discharge port 3 of the casing trough 1, respectively.
A drive pulley 5 is provided, and a flat belt 6 made of a flexible material is wound endlessly rotatably in the direction of the arrow. The driven pulley 4 is attached to, for example, a take-up device (not shown) and is movable in the horizontal direction, so as to apply a predetermined tension to the flat belt 6.

2 and 3 are a partially sectional side view and a plan view showing an enlarged configuration of the flat belt 6 in FIG. 1, respectively, and FIG. 4 is a sectional view taken along the line A--A in FIG. 2. In these figures, a plurality of horizontal rods 7 made of a rigid material are provided on the outer surface of the flat belt 6 at approximately equal intervals at right angles to the running direction of the flat belt 6. The crosspiece 7 is formed, for example, into a substantially U-shape from equilateral angle steel, and is fixed to the flat belt 6 via bolts, nuts, rivets (none of which are shown), or the like. Next, Yokogi 7
A guide roller 9 and a side cover 8 made of a rigid material such as a steel plate and extending between adjacent cross-pieces 7 are provided at both ends thereof, respectively, so as to be rotatable with respect to the cross-pieces 7. In this case, one rotating part of the side cover 8 is
The holes are elongated and extend in the running direction of the flat belt 6, so that the flat belt 6 can run smoothly even if there is a dimensional change between the horizontal legs 7, 7 at the bending part of the flat belt 6 or the engaging part with the pulley. Next, side cover 8
is formed, for example, into a substantially rectangular shape, and is disposed so that most of it protrudes toward the outer surface of the flat belt 6. Further, the side cover 8 is connected to the adjacent side cover 8 either inside or outside at the position of the crossbar 7 so that the flat belt 6 is shielded from both end edges of the flat belt 6 even at the bent portion shown in FIG. It is preferable to form them so that they overlap on the sides, and to provide one of the edge parts parallel to the flat belt 6 so that it also faces the inner surface side of the flat belt 6. Note that a stopper 10 is provided on the inner surface of the side cover 8 so that the rear end edge of the crossbar 7 in the running direction abuts and engages with it. Reference numeral 11 denotes a lodging plate, which is made of rubber or other flexible material and is fixed to the horizontal leg 7 so that it can be tipped down in the running direction of the flat belt 6 when a load of a predetermined value or more is applied to the free end. to form.

The operation of the above configuration will now be described. First, when an object to be conveyed, such as sediment, is inputted from the input port 2 shown in FIG. 1, the object is transferred onto the flat belt 6 and conveyed in the direction of the arrow. Next, when moving from the horizontal transport part to the vertical transport part shown by 1a, the guide roller 9 enters and moves into the guide 12 arranged facing the edge of the flat belt 6, and the flat belt 6 can smoothly transition from the horizontal direction to the vertical direction. In this case, due to the bending of the flat belt 6, the dimensions between the side legs 7, 7 will change, but since one of the rotating parts of the side cover 8 provided between the side legs 7, 7 is made into an elongated hole, It is possible to travel in response to dimensional changes between rotating parts due to bending of the flat belt 6. Next, in the vertical conveyance section 1a, the outer surface side is closed by a casing trough 1, and both end edges of the flat belt 6 are shielded by side covers 8.
Further, as mentioned above, the flat belt 6 has a direction opposite to the running direction of the flat belt 6 (counterclockwise in FIG. 2).
Since a plurality of cross bars 7 and lodging plates 11 made of a rigid material are provided at right angles to the conveyor belt, the conveyed articles are completely sealed and will not cause problems such as scattering or falling. In this case, due to the weight of the conveyed object, a moment is applied that causes the crossbar 7 to rotate in the direction opposite to the running direction of the flat belt 6 (counterclockwise). Since the stopper 10 and the rear end edge of the cross-pole 7 in the running direction abut and engage with each other, rotation or lodging of the cross-pole 7 is prevented. In addition, at the bent portion of the flat belt 6, only the both end edges of the flat belt 6 are supported by the guide 12 and the guide roller 9, but a horizontal rod 7 made of a rigid material is placed at right angles to the flat belt 6.
, it is possible to prevent the inconvenience of the flat belt 6 curving in the width direction. Further, since the side covers 8 are provided on both ends of the flat belt 6 so as to overlap each other, the conveyed object does not fall to the both ends of the flat belt 6.

In this example, an example was described in which sand and sieve residue from a water treatment plant were transported as objects to be transported, but other granular materials such as gravel, coal, ore, chips, grains, etc. Applicable. Further, although the description has been given of a configuration in which a part of the casing trough stands upright, the effect is the same even if the casing trough has an inclined portion, or if the casing trough has an L-shape, an inverted L-shape, or another shape other than the S-shape. Next, the material forming the crossbars provided on the flat belt may be made of materials other than steel, and can be appropriately selected in consideration of the properties of the conveyed object and other factors. It is not limited to only what is shown. Note that the materials constituting the flat belt and lodging plate can be made of other flexible materials such as rubber, and of course composite materials with canvas or other materials built into the core for reinforcement can also be used. It is possible. Furthermore, if the guide roller is provided with a groove so that it runs along the guide rail, it is effective to prevent meandering when the flat belt runs.

[Effect of idea]

Since the present invention has the configuration and operation described above, the following effects can be expected.

(1) By means of horizontal bars and lodging plates installed on the flat belt,
Since it has the effect of containing and holding the conveyed object, it is possible to lift and convey the object in a steeply inclined or vertical position and at a high height.

(2) Since side covers are provided at both ends of the crossbar to cover the edges of the flat belt to accommodate and hold the conveyed objects, there is no scattering or falling of the conveyed objects during conveyance. , not only does it eliminate the need for a cover or skirt on a normal conveyor, but also
Extremely high conveyance efficiency.

(3) Since the flat belt is provided with horizontal beams, the rigidity of the flat belt is high, and the conveyance route can be freely selected, and the effective width of the flat belt can be increased, making it possible to improve the rigidity of the flat belt. It operates extremely smoothly, and is compact and occupies a small area.
