1. Improve the conveyor belt drop hopper.
Improving the conveyor belt drop hopper is one of the useful methods to prevent the early damage of the conveyor belt. Improve the drop hopper at the transfer point of each belt conveyor, so that the ability to pass foreign objects is increased by 2.5 times. Long and large foreign objects are not easy to get stuck between the funnel wall and the conveyor belt during the transportation process, and the foreign objects tear the conveyor belt. Probability. The guide apron at the blanking hopper makes the gap between the conveyor belt and the conveyor belt larger and larger in the direction of the conveyor belt, so as to deal with the problem of coal blocks and gift blocks stuck between the conveyor belt and the speech board, and eliminate the resulting conveyor belt damage. The hopper with a large drop and the internal equipment buffer baffle prevent the material from directly impacting the conveyor belt.
2. Add scraping equipment at the reversing roller. Any scraping equipment should be installed at the reversing roller along the conveyor belt to eliminate the problem of material adhesion at the reversing roller and deal with the partial damage of the conveyor belt caused by the sticking of the roller.
3. The claw pulley at the transition part of the conveyor. Practice has proved that the horizontal strength of the steel rope conveyor belt is lacking. When starting, the part of the conveyor belt formed by the repelling pulley is excessively stressed, which causes the conveyor belt to be torn. The umbrella of the belt wheel is changed to the belt roller. This question can be completely solved .
4. Improvement of the head and tail of the transport and the center forwarding transition. The transition length and transition method of the conveyor head, tail and center forwarding point have a great impact on the service life of the conveyor belt. Reasonable transition design must be carried out to minimize the blind damage caused by the rubber of the conveyor belt, to ensure that the conveyor belt does not appear to be folded or raised, and the material is not leaked at the blanking place.
5. Load reduction of counterweight for conveyor belt of large machine arm support. The service life of the conveyor belt of the stacker arm frame of the coal mine system is very short. The overweight design of the counterweight is an important reason for the excessive tension of the conveyor belt and the premature cracking and aging. After satisfying the foundation of the material tension of the conveyor belt and reducing the counterweight, the application of transporting 1.5 million tons of coal has been extended to 4.5 million tons. The original designed counterweight of the 200,000t mine system stacker-reclaimer arm conveyor belt is 25t (including counterweight roller component). The original German imported tear-resistant steel wire belt works less than 30 million tons and is severely stretched and invalidated. After a load reduction and 6t counterweight reduction, the domestic general steel belt was used, and the workload exceeded 8 million tons.
6. Adjust the direction of material flow. The direction of material flow has an important influence on the service life of the conveyor belt. The material flow and the conveyor belt should run in the same direction, which can greatly increase the service life of the equipment.
7. Part of the conveyor belt damage correction skills to extend the service life
