What is the cause of the deviation of the elevator hopper

Improper installation of the driving shaft of the head wheel and the bottom wheel of the hoist is easy to cause the hopper belt to run off. The main forms are: the transmission shafts of the head wheel and the bottom wheel are in the same vertical plane and not parallel; the two transmission shafts are installed in the horizontal position and not in the same vertical plane; the two drive shafts are parallel, in the same vertical plane and not horizontal.
 
When the above situation occurs, the hopper belt will deviate, which is easy to cause the impact between the hopper and the barrel and the tearing of the hopper belt. In addition, the head of the hoist bears a large dynamic pressure, which can reach about 100 tons. Due to the long-term operation, it is inevitable to have extrusion wear at the bearing position.
 
        Traditional methods are repair welding or machining after brush plating, but both of them have disadvantages: the thermal stress generated by high temperature of repair welding cannot be completely * *, which is easy to cause material damage and lead to bending or fracture of parts; while brush plating is easy to peel off due to the limitation of coating thickness, and the above two methods are metal repair metal, which can not change the "hard to hard" coordination relationship If used together, it will still cause re abrasion.
 
In view of the above problems, European and American enterprises mainly use the repair method of polymer composite materials, among which the mature application of * * is the American Forsyth blue technology system. Polymer materials have super strong adhesion, excellent comprehensive mechanical properties, can be removed without machining. It is not affected by the thermal stress of repair welding, and the repair thickness is not limited. At the same time, the metal material of the product does not have the yielding property, which can absorb the impact vibration of the hoist, avoid the possibility of re abrasion, and greatly extend the service life of equipment components, save a lot of downtime for enterprises and create huge economic value.
