(For example, refer to Patent Documents 1 and 2).

Japanese Patent Laying-Open No. 2015-147639 Japanese Patent No. 5221943

  By the way, the stands and brackets of Patent Documents 1 and 2 are formed by bending (by pressing) a steel plate, and zinc protective plating is applied to solve the problem of corrosion resistance.

  However, damage has occurred due to a drop impact on the stand or the bracket caused by the fall of the conveyed product, and corrosion of the damaged mark portion has progressed, resulting in a problem in durability.

  This problem occurs when the powder fallen on the conveyed product adheres to the stand or the bracket, and the corrosion greatly increases due to the cause of the adhesion.

  Therefore, a long-term challenge imposed on each manufacturer was the battle against corrosion resistance, measures for strength and weight reduction, and cost comparison against these.

  In other words, if the specification is reduced in favor of weight reduction, the strength tends to be inferior, and if the specification is reduced, such as by reducing the plate thickness, the material cost will be reduced but it will be weak against rust, so it must be covered with heavy coating specifications. This was one of the conventional measures.

  Carbon steel (generally rolled steel for structural use JISG3101), which is commonly used, is inexpensive and rich in workability, but has a drawback that it is vulnerable to rust. The method of raising has been taken.

  In addition, stainless steel materials are the most commonly used as a countermeasure against rust, but the range of use has to be limited because of increased costs.

  Similarly, the use of a resin material or a resin coating material can be mentioned as a countermeasure against rust. However, since the strength and impact resistance are inferior, the range of use is also limited.

  In addition, plating processing typified by hot dip galvanized material may be adopted, but plating is performed on the original steel material that guarantees strength, so the product weight increases and plate thickness and structure restrictions that can be plated In addition, there is a problem such as the above, and the processing method has some restrictions, so that the cost tends to increase overall.

Even for products, even if rust occurs on idler stands and brackets that are roller support structures for conveyors installed in long distance conveyors, high places, coastal areas, and on ships, touch-up repair paints and parts・ Maintenance measures against rust such as inability to replace the product were extremely difficult. The same problem exists in the conveyor frame.
Therefore, the present invention is to solve the above-mentioned problems.

  In order to solve the above-described problems, the present invention is directed to a pair of steel plates that stand on the left and right sides of a center portion of a horizontal member that is laid horizontally on a conveyor frame across a carrier frame of an endless traveling belt. A bending center stand and a bent steel side stand standing from both ends of the horizontal member are provided, respectively, and the opposite pair of center stands are supported through the center of the center roller for supporting the back surface of the carrier side belt. Both ends of the shaft are supported in a non-rotatable and detachable manner, and both ends of the support shaft that penetrates through the center of the side roller for supporting the back surface of the carrier side belt to the opposite center stand and side stand are placed in a non-rotated state. In the belt conveyor that is detachably supported, the center stand and the side stand have meshes mainly composed of Al, Mg, and Zn. To adopt processing a configuration in which the (ZAM · registered trademark).

  Further, a parallel horizontal member crossing under the carrier side of the endless running belt is horizontally mounted on the conveyor frame, and a pair of bent steel plate center stands standing on the left and right sides of the center portion of the horizontal member are also provided. Each side stand is made of bent steel plates that stand up from both ends, and both ends of the support shaft that penetrates through the center of the center roller for supporting the back surface of the carrier side belt in the opposite pair of center stands are attached and detached. Support both ends of the support shaft that passes through the center of the back side support side roller of the carrier side belt in a non-rotatable and detachably supported manner on the center stand and the side stand facing each other. Attach the upper end of the bent steel brackets to the conveyor frames on both sides of the belt return side, and run the above In a belt conveyor that supports both ends of a support shaft that passes through the center of a return roller that supports the back side of the belt on the return side of the belt in a non-rotating state and is detachably supported, the bracket includes Al, Mg, and Zn as main components. A structure with plating (ZAM / registered trademark) is adopted.

  Furthermore, the structure characterized by having plated the steel material which comprises the said conveyor frame as a main component (ZAM * registered trademark) is used.

  As described above, according to the belt conveyor of the present invention, the center roller for supporting the back surface of the carrier side belt, the center stand for bending the steel plate supporting the support shaft of the side roller, the side stand, and the surface of the return side belt are provided. Plated brackets and conveyor frames of steel plates that support the support shaft of the return roller to be supported are plated with Al, Mg, and Zn as the main component, so anti-corrosion measures are more than conventional zinc-only plating. In addition to exhibiting a remarkable (rust-proofing) effect, there is an excellent effect that complicated maintenance is not required as the durability is greatly improved. Of course, there is no need for a method of increasing the plate thickness as a means for strengthening rust.

  Also, a zinc-based protective coating containing magnesium that is dense and highly adherent over time due to the effects of aluminum and magnesium contained in the main components by plating treatment (coating) containing Al, Mg, and Zn as main components. Is formed on the plating surface, and the protective film suppresses the progress of corrosion of the plating layer, and the dense protective film that has melted out of the above-mentioned plating treatment film is caused by the impact of the cut surface by processing or the falling object during operation. Corrosion is suppressed by the action of sacrificial anticorrosion covering the area exposed by the wound. That is, the greatest feature is having a self-repairing ability.

  Further, since the protective film formed on the plating surface is dense and has high adhesion, in order to suppress permeation of corrosion factors, high durability is maintained for a long time, and durability is remarkably improved.

  In addition, it may be caused by corrosion due to local rusting concentrated on the painted part of the uneven coating during processing, or rust due to scratches that are likely to occur on the conveyor frame during or after transportation of the stand or bracket product. It is possible to prevent a decrease in strength.
