Its main function is to take coal from the coal tower and load it into the carbonization chamber according to the operation plan after metering. The cover device is one of the important parts of the coal loading car. The cover device mainly uses an electromagnet to suck the furnace cover to make it suspended, and closes and opens the furnace cover through the hydraulic cylinder operation. Since the electromagnet works in a high temperature environment for a long time and often fails, it is a vulnerable spare part that needs to be replaced frequently. The existing replacement method is to replace the electromagnet by lifting it with a jack. The base of the electromagnet and the replacement position are only about 500mm away from the ground, and the angle of about 45° with the ground is the best replacement position. Each time the replacement is made, the angle between the base of the electromagnet and the ground cannot be guaranteed to be the same due to the error of the hydraulic and transmission system. When replacing, the personnel need to lie on the ground to work, and the working space is small and cannot be operated by multiple people. The electromagnet weighs 145kg, and it is difficult to align during operation, the replacement efficiency is low, the replacement safety risk is high, and the replacement time is long, which affects production, and the contradiction between production and maintenance is prominent. In addition, if the electromagnet is suddenly damaged during the production process, it needs to be replaced as soon as possible. Since the working temperature of the electromagnet is high and the natural cooling time is long, in order to resume production as soon as possible, it needs to be replaced before the electromagnet cools down to normal temperature. The replacement operation requires manual work and is prone to burns. Therefore, how to provide an efficient, safe and convenient method for replacing electromagnets is an urgent problem to be solved by technicians in this field. Utility Model Content
