Research on the fault of steel rope conveyor belt
Long-term operation of the steel wire rope conveyor belt, prone to wear, deformation, broken wire and other failures, over time the strength of the steel wire rope conveyor belt will decline until broken, the most serious situation is that it may cause casualties to bring huge economic losses to the enterprise. In order to avoid the occurrence of the above situation, here is a simple analysis of the reasons for the failure of the steel wire rope conveyor belt and solutions.
Take coal mining as an example, in the transportation roadway, mining roadway and mining area up and down the roadway will use wire rope conveyor to transport materials, but generally will not transport the texture of hard angular materials. The frequent failure of the steel wire conveyor belt in the coal mine conveyor system is tearing or even breaking the belt, and there are many other factors in addition to normal wear and tear. In order to prevent belt breakage, the maintenance personnel of the conveyor system should extend the service life of the wire rope conveyor belt as far as possible, reduce unnecessary downtime, and reduce the accident rate.
Wire rope conveyor belt joint twitch and broken wire is a frequent fault, the covering rubber suffered serious damage or corrosion of the joint end will cause the conveyor belt joint twitch. To distinguish the fault type of the steel wire rope conveyor belt can find out the cause of the fault.
1. Fatigue damage
Due to the space limitation, the steel wire rope core needs to be bent repeatedly and constantly bypass the roller and pulley when the conveyor belt is running. The repeatedly bent wire rope core is subjected to fatigue load in each working cycle, so repeated fatigue damage will be caused. In order to extend the service life of the steel wire rope conveyor belt, the driving device, installation size and drum quality can be comprehensively considered.
2. Uneven distribution of conveyor belt tension
The steel wire conveyor belt is usually a trough structure to increase the loading area of coal. When the wire rope conveyor belt transitions from the horizontal section to the trough section, the edge of the conveyor belt will be subjected to greater tensile pressure than the middle. Uneven distribution of belt tension will make the belt more likely to break.
3. Excessive external force
When the conveyor belt is severely stretched due to sudden excessive external pressure, the conveyor belt will be damaged or even broken. At the same time, the material stuck in the guide chute or the parting plate will also lead to the risk of broken tape.
