Description

Step type impact-resistant guide box Technical Field The utility model belongs to the technical field of sintering systems, and particularly relates to a stepped impact-resistant guide box. Background In the sintering system, the guide box is mainly used for orderly guiding high-temperature sintering ores into a lower conveying device or a storage bin from upper equipment, and the structure of the guide box is required to have good high-temperature resistance, impact resistance and wear resistance so as to ensure that the structure is stable in the process of high-speed falling of materials, effectively buffer the impact force of the materials and avoid damage to subsequent equipment. The guide box is used as an important transition structure for connecting the sinter output and the conveying system, and the operation reliability of the guide box directly influences the overall operation efficiency of the sintering system and the equipment maintenance frequency. At present, the body structure of the traditional guide box is mostly in a grid-shaped design, and a buffer mode of 'material beating' is formed by filling grids with sinter. However, in the falling process of the high-temperature red ores, the ores are high in temperature, hard in particles and large in impact force, so that the grid steel plates adopted by the bodies are frequently subjected to severe impact and high-speed abrasion, deformation, fracture and even falling phenomena are easy to occur, and the stability of the whole structure is further damaged. In long-term operation, the structure of the guide box is frequently damaged, and a large amount of overhauling and repair welding are needed, so that the maintenance cost is increased, and the continuous and stable production of the sintering system is seriously influenced. Disclosure of utility model The utility model provides a step type impact-resistant guide box, which is used for solving the problems that a grid steel plate of the conventional guide box is easy to deform, break or fall off and the maintenance cost is increased in the prior art. The utility model adopts the technical scheme that the stepped impact-resistant guide box comprises a main bracket, wherein one side of the main bracket is fixedly provided with a plurality of slide carriages which are transversely and longitudinally staggered, so that a plurality of cavities are formed on one side of the guide box; Wherein, the casting material is cast in each cavity, the upper end of the casting material is higher than the highest point of the cavity, and the casting material in the adjacent cavity are integrally fused and formed to form an integral inclined casting material layer; A step part is formed in the middle of the surface of the castable layer, and the upper surface of the step part is parallel to the horizontal plane. The main support comprises an underframe, side support frames and an inner support frame, wherein the slide carriage is transversely and longitudinally arranged on the inner support frame in a crossing manner, the side support frames, the inner support frame and the underframe are sequentially welded to form a triangular structure, and a middle support frame is arranged between the underframe and the inner support frame. The two sides of the main support and the two ends of all the cavities are provided with side plates, the height of the side plates is higher than that of the casting material layer, and the side plates are used for preventing materials from falling from the two sides of the main support. The anchoring parts are C-shaped steel bars, part of the anchoring parts extend upwards from the bottom of the cavity in the same cavity, and the other part of the anchoring parts are welded at the position above the cavity. The anchoring piece is fixedly connected with the metal grid plate. The beneficial effects of the utility model are as follows: The utility model forms the whole inclined wear-resistant layer by arranging the anchoring piece and the metal grid plate in the cavity and utilizing the integral pouring structure, thereby effectively improving the structural strength and the impact resistance of the material guiding box, and arranging the step part structure in the middle of the pouring material layer, a certain amount of sintered ore can be reserved in the early stage of use, the lower layer material is fully baked in a high-temperature environment, the pouring material is promoted to gradually reach the ideal sintering strength, the initial large-area abrasion is avoided, the step part naturally falls off in the subsequent operation, a new homogeneous wear-resistant working surface is formed, the integral abrasion tends to be stable, the service life of equipment is prolonged, and the maintenance frequency is reduced.
