With simple structure, small footprint, low power consumption and large conveying capacity, the Belt bucket elevator is widely used in the bulk material lifting system of electric power, building materials, metallurgy, chemical industry, cement, mining and other industries.
Belt bucket elevator use a series of hoppers fastened to a traction chain or tape to transport bulk materials upward in a vertical or near-vertical direction. In order to ensure the safe operation of the wire rope and better grasp the damage rule and prevention method of the wire rope, the engineer of the mechanical technology department analyzed the causes of wire rope damage according to the structure of this equipment, including:
1.Jump over the prevention device does not jump back in the pulley device pulley arrangement gap is too large.
Wire rope or rope to prevent more than 20% of the diameter of the device can not meet the requirements of rigidity, between set jump rope, resulting in damage to the rope.
2.When the inverted pulley bottom groove diameter, wrap angle and groove wall wear close to or more than the specified requirements.
The wire rope corresponding squeezing pressure and bending stress will increase.
3. Pulley or roller material properties can not meet the requirements, which will also lead to damage to the wire rope due to excessive extrusion stress
4. For winding devices, bend pulleys, etc. Lubrication and leads to premature wiring due to routine maintenance.
5. For the first installation, the wire rope bending or twisting unevenly arranged on the reel or the first climbing did not take measures.
6. Pulley or roller position improperly which make the wire rope in or out of the pulley and roller. Its deflection angle increases, that is the center line of the wire rope and perpendicular to the axis of the pulley or roller plane clamps are greater than 4 °.
