Description

  The present invention relates to an inclined conveyor belt in which spill-proof flanges are erected on both sides in the width direction of a transport surface, and a transported object is accommodated and transported between both spill-proof flanges.

A sloping conveyor belt that has flexible spill-proof flanges (also called ear rails) on both sides in the width direction of the conveying surface of the belt main body, and has a horizontal rail between both spill-proof flanges, is a drive pulley. A belt conveyor device is known which is wound around a driven pulley, a guide pulley, and the like so as to convey an object to be conveyed such as earth and sand. Some horizontal rails of such an inclined conveyor belt are provided with a reinforcing layer such as canvas inside (for example, see Patent Document 1).
Japanese Utility Model Publication No. 6-49411

  In this type of inclined conveyor belt, a large load is applied to the horizontal beam when conveying a heavy object such as earth and sand. Therefore, it is necessary to increase the rigidity of the horizontal beam to counter this load. In order to increase the rigidity of the cross rail, it is conceivable to increase its thickness. However, if this is done, the weight of the inclined conveyor belt will increase.

  Recently, the market demands to reduce the weight of inclined conveyor belts, but it is difficult to reduce the left and right spill-proof flanges (wave bars). is required. However, if it does so, the rigidity of the crosspieces becomes low, and there is a risk of hindering conveyance.

  In addition, as described in Patent Document 1, sufficient rigidity cannot be obtained simply by inserting a reinforcing layer such as a canvas inside, and when a heavy load is applied, the horizontal beam is bent and transported. There is a risk that it will be unbearable.

  The present invention has been made in view of the above-described problems of the prior art, and an object of the present invention is to provide an inclined conveyor belt in which a horizontal rail is thinned to reduce weight and not to impair rigidity.

According to the present invention, the above problem is solved as follows.
(1) A spill prevention flange that can follow the deformation of the belt body is erected on the conveying surface of the belt body along both side edges, and the belt body between the spill prevention flanges arranged on the left and right sides. In the inclined conveyor belt in which the horizontal rail is erected on the belt body at a predetermined interval along the longitudinal direction, a reinforcing plate made of a hard material is embedded in the horizontal rail.

(2) In the above item (1), the upper end surface of the reinforcing plate is exposed on the upper end surface of the cross rail.

(3) In the above item (1) or (2), the horizontal beam is composed of a skirt part fixed to the belt body and a horizontal beam body erected on the hem part, and the lower end of the reinforcing plate. The part is made to reach the vicinity of the bottom surface of the skirt part.

(4) In any of the above items (1) to (3), the reinforcing plate is made of a hard synthetic resin or hard rubber, and a tapping screw is screwed into the reinforcing plate from the outside of the spill prevention flange to spill the horizontal beam. Secure the retaining flange.

(5) In any one of the above items (1) to (4), at least a part of the cross rail and the reinforcing plate is inclined toward the traveling direction of the belt main body.

(6) In any one of the above items (1) to (5), a reinforcing canvas is embedded in the cross rail together with the reinforcing plate.

According to the present invention, the following effects can be achieved.
(a) According to the invention described in claim 1, by embedding a reinforcing plate made of a hard material in the horizontal beam, the rigidity of the horizontal beam is increased and the strength is increased. The weight can be reduced.

(b) According to the second aspect of the invention, by exposing the upper end surface of the reinforcing plate to the upper end surface of the horizontal rail, the wear resistance of the upper end portion of the horizontal rail can be improved.

(c) According to the invention described in claim 3, since the horizontal beam main body is erected on the hem and the lower end of the reinforcing plate is made to reach the bottom of the hem, the horizontal beam main body is bent from the hem. It becomes difficult and the strength becomes larger.

(d) According to the invention described in claim 4, by tapping the tapping screw into the rigid synthetic resin or hard rubber reinforcing plate and fixing the cross rail and the spill-proof flange, the tapping screw is not easily removed. , Rigidity and durability are improved.

(e) According to the invention described in claim 5, the resistance against the object to be conveyed can be further increased by inclining the horizontal rail toward the traveling direction of the belt main body.

(f) According to the invention described in claim 6, the reinforcing effect can be further enhanced by burying the reinforcing canvas together with the reinforcing plate in the horizontal rail.

Embodiments of the inclined conveyor belt of the present invention will be described below with reference to the drawings.
FIG. 1 is a schematic side view of a steeply inclined conveyor apparatus including a first embodiment of the inclined conveyor belt of the present invention.

  As shown in FIG. 1, the inclined conveyor belt (1) is wound around a driving pulley (2), a driven pulley (3), and guide pulleys (4), (5), (6), and (7) arranged above and below. It has an endless structure, and an upward steep inclined portion (8) is provided between the guide pulley (4) and the guide pulley (5), and a downward steep inclined portion is provided between the guide pulley (6) and the guide pulley (7). (9) is formed. The inclined conveyor belt (1) is rotated in the direction of the arrow (A) by the driving pulley (2), and in the lower carry-in section (10), the object to be transported such as earth and sand loaded on the inclined conveyor belt (1) is conveyed. A thing is sent to the discharge part (11) through the upward steeply inclined part (8), and is discharged to the hopper (12) provided therebelow.

2 is an arrow view in the direction (B) of FIG. 1, and FIG. 3 is an enlarged sectional view taken along line III-III of FIG.
As shown in FIG. 2 and FIG. 3, spills of so-called wave bars are formed on both sides in the width direction of the conveying surface (14 a) of the belt main body (14) in the inclined conveyor belt (1) along both side edges. A retaining flange (15) is erected. On the belt main body (14) between the left and right spill prevention flanges (15), (15), a cross rail (16) is provided at a predetermined interval in the longitudinal direction of the belt main body. By accommodating and transporting the object to be transported in the space (17) partitioned by the horizontal rail (16), the object to be transported does not fall even when traveling upwardly steeply inclined portion (8).

  As shown in FIG. 3, the crosspiece (16) is erected at the center of the skirt (16a) and the hem (16a) integrally bonded or vulcanized and welded to the belt body (14). And the crosspiece main body (16b). A reinforcing plate (18) made of a hard material such as metal, hard synthetic resin, or hard rubber is embedded in the central portion of the crosspiece main body (16b). This reinforcing plate (18) extends across the entire width of the horizontal beam (16), the lower end extends to the vicinity of the bottom surface of the skirt (16a), and the upper end surface is exposed at the upper end surface of the beam main body (16b). It is. Thus, by exposing the upper end surface of the reinforcing plate (18) to the upper end surface of the crosspiece body (16b), the wear resistance of the upper end portion of the horizontal crosspiece (16) can be improved.

  As the metal plate, lightweight aluminum alloy, Ni—Ti alloy or the like is suitable, and as the hard synthetic resin, ebonite or a similar hard resin is suitable, but it is not limited to these, and a hard material is used. If so, implementation is possible. It is preferable to put reinforcing canvas (19) similar to the conventional one on both sides of the reinforcing plate (18).

  The horizontal rail (16) has a structure independent of the spill prevention flange (15), and tapped from the outside of the spill prevention flange (15) at both ends of the horizontal rail (16) as shown in FIG. A fixed structure can be obtained by screwing in the screw (20). When the reinforcing plate (18) is made of a hard material other than metal, the tapping screw (20) can be directly screwed into the reinforcing plate (18), and the tapping screw (20) is less likely to come out compared to the conventional structure of screwing into a rubber material. .

  FIG. 4 shows a second embodiment of the present invention in which the cross rail (16) is modified. This horizontal beam (16) is an example of a so-called K-shaped horizontal beam that is inclined from the skirt (16a) toward the traveling direction (arrow direction) of the belt main body (14). In this structure, the reinforcing plate (18) has a parallelogram shape that is inclined in the same direction as the horizontal rail (16) and whose upper end surface and lower end surface are parallel to the belt body (14).

  FIG. 5 shows a third embodiment of the present invention in which the cross rail (16) is further modified. This horizontal beam (16) is an example of a so-called TC type horizontal beam that rises vertically from the skirt (16a) and inclines in the middle of the belt main body (14) in the traveling direction (arrow direction). In this structure, the reinforcing plate (18) rises vertically from the skirt (16a), inclines in the same direction as the cross rail (16), and the upper end surface is parallel to the belt body (14). It has become.

  4 and 5, the entire or front end of the horizontal beam 16 is inclined in the conveying direction of the inclined conveyor belt, so that the structure has a large resistance to the object to be conveyed and is reinforced. By adding the plate (18), the strength can be further increased.

  As described above, by embedding the reinforcing plate (18) made of a hard material in the horizontal beam (16), the rigidity of the horizontal beam (16) is increased and the strength is increased. It is possible to reduce the thickness of the inclined conveyor belt without losing its strength.
