Technical Field
The application relates to the technical field of four-roller crusher equipment, in particular to a roller leather replacing device of a four-roller crusher.
Background
The four-roller crusher is mainly used for crushing auxiliary sintering products such as coke, coal, raw materials, limestone and the like in a raw material sintering plant, and can crush materials with required granularity by adjusting the gap between an upper roller and a lower roller. The four-roller crusher mainly comprises a frame, a belt wheel, a bearing, rollers, a speed reducer, a motor, a lubricating device and the like, and in the long-term operation process, the rollers are worn unevenly, the granularity of discharged materials is influenced, the roller leather can be relieved by turning, and the roller leather needs to be replaced when the thickness of the roller leather is reduced after multiple times of turning. The traditional mode of installing the roller skin is as shown in figure 1, transversely place the roller skin subaerial fixed, use electric block to hang the one end of roller core bearing earlier and penetrate the roller skin in, remove electric block after penetrating the roller skin, then use chain block and wire rope to pull one section of entering, use electric block to hang at the other end, both ends cooperate together to penetrate the roller core in the roller skin, need the manpower to bump into the cutting ferrule of roller core and install in the roller skin. When the method is used for installation, the roller skin needs to be horizontally placed on the ground for fixation, the electric hoist needs to be matched with an iron bar when the roller core is installed, the clamping sleeve of the roller core is manually hammered to the position, a large amount of manpower is needed, and the operation efficiency is not high; the small check block needs to be welded while being smashed in the operation process for fixing, so that the operation is inconvenient, the operation efficiency is not high, and time and labor are wasted. Quality and safety problems are easy to occur due to improper matching in the operation process, and internal elements can be damaged to cause object striking accidents.
