Description

Fire prevention transformation structure of coke oven coal charging car excitation line Technical Field The utility model belongs to the technical field of electrical equipment protection, and particularly relates to a fireproof transformation structure of an excitation wire of a coke oven coal charging car, which is suitable for fireproof transformation of the excitation wire in a severe working environment or similar working environment of the coke oven coal charging car of a coke oven plant. Background In the coal coking industry, the coke oven of a coal coking enterprise is in a very severe environment and is in a high-temperature state and is filled with a large amount of dust, and meanwhile, frequent moving operation, toxic and harmful gas and the like are accompanied. Under the severe working condition, the failure rate of the electrical equipment is always at a higher level, and the failure rate of the coal charging car is particularly prominent in various electrical equipment. The coal charging car is an indispensable important component in four locomotives of the coke oven, and belongs to key mobile electrical equipment. The main working flow of the coal charging car is to accurately transport coal from a coal bunker to the inside of a coke oven and place the coal in a carbonization chamber for coking operation. Due to the operation characteristics, the coal charging car can be directly contacted with open fire of the furnace body, so that the working environment temperature of the coal charging car can reach nearly thousands of DEG C. The high temperature environment forms a great threat to the electrical system of the coal charging car, and once the electrical system fails, the normal production order of the coke oven can be directly disturbed, and serious production delay and economic loss are generated. In the current electrical protection of coal-charging vehicles, the exciting wire is an important component of the exciting system and is usually protected by wrapping a fire-proof belt. However, in the practical application process, the protection mode has obvious defects. On one hand, the fireproof belt has uneven quality, is difficult to maintain stable fireproof performance under the test of high temperature and severe environment for a long time, and on the other hand, the quality and effect of the bundling can not be effectively ensured due to the influence of various factors when an operator performs the bundling operation of the fireproof belt, and the bundling tightness, integrity and other problems are caused by the bundling experience and responsibility difference of the operator. The factors are combined, so that the actual fireproof effect of the fireproof belt is greatly reduced, and the damage of high temperature to the excitation wire cannot be effectively prevented, so that the excitation wire is frequently blown. The frequent burning of the excitation wire not only means that a great amount of manpower, material resources and time cost are required to be input for frequent replacement, but also the production of the coke oven is forced to be interrupted or run at a reduced speed in the replacement process, so that the production efficiency is seriously reduced, the operation cost and the production management difficulty of enterprises are increased, and the technical problem to be solved is urgent to restrict the efficient and stable production of the coke oven. Disclosure of utility model The utility model provides a fire prevention transformation structure of an excitation wire of a coke oven coal charging car, which can obviously improve the fire prevention, fire resistance and high temperature resistance of the excitation wire by carrying out fire prevention transformation on the excitation wire on the coke oven coal charging car, so that the excitation wire can stably operate in complex environments such as severe high temperature, dust, toxic and harmful gas of the coke oven, frequent movement and the like, and the shutdown event of the coal charging car caused by the fault of the excitation wire is effectively reduced, thereby ensuring the normal operation of the coal charging car and ensuring that the production of the coke oven can be carried out efficiently, stably and continuously. The technical scheme for solving the technical problems is as follows: The utility model provides a fireproof transformation structure of an excitation wire of a coke oven coal charging car, which comprises an excitation wire, wherein a plurality of waste oil pipes are sleeved on the outer side of the excitation wire, and when more than two waste oil pipes are arranged, the adjacent waste oil pipes are connected and fixed through metal wires. As a further improvement of the technical scheme of the application, the metal wire is made of iron wires, steel wires or copper wires. As a further improvement of the technical scheme of the application, the outer side of the waste oil pipe is also
