Under the impact of ore, the chain plate For Sale of Apron Feeder For Sale and its supporting mechanism are deformed, which makes the bearing of Apron Feeder For Sale damaged frequently and the maintenance rate is very high. In this paper, the finite element analysis software Abaqus is used to carry out dynamic and static simulation analysis on the ore impact support mechanism (the force structure composed of channel steel and I-steel). It can be found that the stress at the rigid support of chain plate is large in the impact process. The deformation of the chain plate and the supporting mechanism makes the original 5-point support become 2-point support at both ends, thus increasing the force on both sides of the bearing, thus aggravating the damage of both sides of the supporting bearing. Through the analysis of the impact characteristics of Apron Feeder For Sale chain plate support mechanism, find out the problem, and then improve the Apron Feeder For Sale, reduce the impact of ore on the bearing, improve the service life of the equipment.
Apron Feeder For Sale is a kind of heavy equipment widely used in mine feeding, its main function is to send the ore from the ore funnel to the belt conveyor more evenly. In the process of work, under the impact of ore, the bearing in the chain plate and its supporting roller system is easy to be damaged, and the failure rate and maintenance rate are high. Through on-site observation and analysis, it is found that there are two direct factors affecting the failure of Apron Feeder For Sale: first, the ore directly impacts the chain plate from 10m height, and the impact force is relatively large, so that the chain plate and support channel steel deformation or even fracture; Second, under the impact force, the middle part of the chain plate lining plate and the supporting foundation of the idlers will deform and sink after being used for a period of time, resulting in the failure of 3 of the 5 supporting idlers in each row and the failure of only the outer 2 idlers. As a result, the outer idlers are easily damaged. In this paper, the impact of ore on the chain plate and the supporting mechanism (I-steel, channel steel) is analyzed and studied, and the supporting mechanism is improved, so as to reduce the impact of ore on Apron Feeder For Sale and extend the service life of Apron Feeder For Sale.
When the ore falls down, the impact force first passes through the chain plate to the bearing, and then transmitted to the support frame to deform it, so that the 5 point support becomes 2 point support, so the chain plate is easy to damage. Therefore, the main reason For the failure of Apron Feeder For Sale is the structural deformation of the support frame. Therefore, as long as the support mechanism is analyzed, the impact force can be simplified to the support frame.
In the process of ore impact, the stress at the support is great, and the maximum stress occurs near the middle of the support (impact point). The stress will cause the deformation of the support, so that the Apron Feeder For Sale is changed from 5-point support to 2-point support, resulting in easier damage of the bearing. 2) The analysis results after improvement show that the force of the improved support has been significantly improved, the force is more uniform, and the damage effect of the impact force is significantly reduced. Prove that this scheme is feasible. This transformation mode is of great significance to the factories that have installed Apron Feeder For Sale. Under the condition that the existing conditions do not change, the construction time is short in this way, the transformation cost is low, the maintenance amount can be reduced, the production efficiency can be improved, and the maintenance cost is extremely important.
