        Detailed introduction
        
                            Whether the choice of the replacement process of the rope lifting belt is reasonable is the key to the length of the replacement time and labor intensity of the rope lifting belt. Taking the replacement of 1700m steel wire rope lifting belt in Dongda Lane of Gengcun Coal Mine as an example, this paper introduces the method of replacing steel wire rope lifting belt with the help of elevator. N-TGD type steel wire rope core belt bucket elevator is an important equipment for the vertical transportation of dry powder materials or small granular materials, with large throughput, high lifting height, stable and reliable operation, long service life, small environmental pollution and other characteristics, its deficiency is not suitable for conveying high temperature materials. This paper introduces the structural characteristics of N-TGD type steel wire rope core belt bucket elevator, and focuses on the key points of installation and debugging of this equipment. The rubber rope lifting belt used in coal mine will slip and cause serious wear.
        

        
	 

        
Under certain conditions, when the working resistance of the ring rope lifting belt reaches the limit value of friction force, the rope lifting belt will slip on the contact surface with the equipment, which makes the rubber belt unable to operate normally, and also causes serious wear to the belt body. In the process, a lot of heat will be generated. Thus, the conveyor rope lifting belt is constantly damaged under the double action of wear and heat, and the rubber filter belt is broken until it is broken. In order to ensure that the steel wire rope lifting belt conveyor equipment can work normally, the mining steel wire rope lifting belt must meet the following conditions: 1. The tension acting on the steel wire rope lifting belt should make the circumferential force on the transmission drum transmitted to the belt body through friction, and the rubber wire rope lifting belt and the drum must ensure that there is no skid; 2 The tension acting on the rope lifting belt should be large enough to make the sag between the two sets of rollers less than a certain value; 3. The fatigue damage caused by long-term use is due to the cumulative damage caused by the rubber conveyor belt in the continuous working process. Due to the working nature of the coal mine transport belt itself, the running time of the belt body is generally longer, and the discontinuity time is shorter. Due to the entry of cinder, dust, etc., the friction on the surface of the rubber transport belt and mechanical equipment continues to increase, resulting in the material falling off of the belt body itself, resulting in the accumulation of material falling off. In addition, due to the constant change of stress in the transmission process of the steel wire rope lifting belt, the internal strength of the material gradually decreases, the damage continues to accumulate, and finally the fatigue damage is caused; 4 The quality of the nylon rope lifting belt is affected by many aspects such as the rubber cover, the number of padding layers of the nylon belt, the initial tension, the hot vulcanization of the rubber belt and the quality of the rope lifting belt joint. Wire rope core belt conveyor is widely used in all walks of life, coal mine raw coal transportation, whether from the transport efficiency or from the labor intensity, the belt conveyor to transport raw coal is the first choice, and the wire rope lifting belt due to long-term wear and tear need to be replaced is inevitable.
