Description
Technical Field
The utility model relates to the technical field of sintering machines, in particular to an arching and deviation eliminating device of a sintering machine trolley.
Background
The sintering machine trolley is a core part of the sintering machine, and the stable operation of the sintering machine trolley is the key of the whole system, but the problems of arching and deviation of the trolley exist in actual production. The intelligent management system of the sintering machine trolley is used in each large sintering plant nowadays, and the intelligent management system has the functions of detection, identification, early warning and the like, and lacks the function of solving the problems.
Arching: in the operation process of the belt sintering machine, when the trolley passes through the tail star wheel and enters a lower horizontal track (a return lane) through a tail curve, in the driving process, the tail star wheel toothed plate pushes the trolley to move forwards, the front working face of the toothed plate is contacted with a trolley rear wheel cutting sleeve and generates a thrust Fz for enabling the trolley to move towards a cutting plane, the force has a horizontal force Fd and an upward friction component Ff, the larger the thrust is, the larger the friction component is, when the moment generated by the friction component is larger than the moment of the self weight of the trolley, the trolley rear wheel can be lifted upwards, the star wheel continuously rotates, and the front end of the rear trolley is contacted with the trolley clamping wheel and tightly extruded at the moment that the trolley clamping wheel leaves the toothed plate, so that the trolley cannot fall to the track. In this way, each hanging trolley can pass through the stress process, so that the trolley on the return track has the phenomenon of shoulder-building and arching. In the prior art, the problem of arching of the trolley is generally solved in two ways. Firstly, a special boss track is adopted, the running track is changed locally, and the moment generated by friction component force is reduced, so that the arching of the sintering machine trolley is reduced. The existing special track is inconvenient to wear, replace and maintain, has construction hidden danger, long replacement time and high cost; secondly, the fixed rail is adopted, the method solves the problem that the trolley is strongly pressed under the condition that friction force is not eliminated, the method aggravates the wear of the trolley end, a triangular groove is formed, the trolley leaks air, production is reduced, correction is not thorough, the trolley still has arching of different degrees, the load of a motor is increased, a motor is damaged, a sintering machine frame and a trolley rail are damaged, and accidents such as trolley derailment and the like are caused.
Deviation: the reasons for the deflection of the trolley are mainly that the metal materials are deformed due to the influence of long-term heating loads of a rack, an air box, a driving wheel at the head and the tail of a track and the like in the production and use process, and the original installation precision is damaged due to the combined action of factors such as uneven settlement of a factory building foundation and the like, so that the deflection of the trolley is caused in the running process. The deflection of the trolley can have many adverse effects on the equipment itself and on production, such as: the service lives of the trolley wheels and inner cavity parts thereof, abrasion and displacement of the trolley travelling rail, abnormal running state of the machine head and the machine tail and the like are reduced, the abnormal running state of the machine head and the machine tail can cause deformation of related components of a curve, meanwhile, the deformation can aggravate the deflection of the trolley, the trolley is viciously circulated until the trolley is separated from the travelling rail, a great amount of time is required to be spent for trimming recovery equipment after the trolley is separated from the travelling rail, and the production rhythm can be seriously influenced.
The intelligent management system for the sintering machine trolley generally provides operation state management for the sintering machine trolley through modes such as video identification, laser ranging, track weighing and the like, but is limited to an early warning function, and manual operation is needed to adjust and intervene when the system judges that the sintering machine trolley has arching and deviation phenomena, so that automatic elimination of the arching and deviation phenomena cannot be realized.
