During the use of the mine car, due to normal aging of various parts of the mine car or improper operation by construction personnel, damage to the mining cart occurs, which requires timely maintenance to avoid further damage to the mine car, improve the integrity rate of the mining cart, and ensure the normal operation of the mining cart. At the same time, maintenance personnel need to strengthen daily inspection and maintenance work according to the integrity standards of mining cart, reduce the scrap rate of mine car, extend the service life of mine car, and improve economic benefits.
What is the cause of the damage to the mine car?
(1) Due to the fact that underground water in the mine contains certain alkalinity, especially in the humid summer season, it is highly corrosive to the mine car. The mixture of rock and water adheres to the mine car, causing serious corrosion and aging of the mining cart; When manually cleaning the mine car with sticky waste, the mining cart body is also damaged to a certain extent, thereby shortening the service life of the mine car.
(2) The use and management of mine cars are not standardized. During the process of using mine car, some construction personnel operated improperly, resulting in hard blows or hard collisions between mine cars, resulting in deformation of mining carts and causing damage or scrapping.
(3) The maintenance personnel did not properly inspect or repair the slightly damaged and aged mining cart in a timely manner, causing the mine car to operate with defects, increasing the degree of damage to the mine car, leading to early scrapping of the mine car.
(4) When the mine car falls off the track during operation, it does not follow the specified requirements to resume the track, and the mine car is forcibly pulled and dragged to resume the track, resulting in damage to the mining cart.
