Description

Arch camber and deviation eliminating device for sintering pallet

Technical Field

The invention relates to the technical field of sintering machines, in particular to an arch camber and deviation eliminating device of a sintering machine trolley.

Background

The sintering pallet is the core part of the sintering machine, the stable operation of the sintering pallet is the key of the whole system, but the problems of arching and deviation of the sintering pallet exist in the actual production. The intelligent management system for the sintering machine trolley used in each large sintering plant has the functions of detection, identification, early warning and the like, and lacks of problem solving functions.

Arching: when the sintering machine runs, when a trolley enters a lower horizontal rail (a return lane) through a tail star wheel and passes through a tail bend, in the driving process, a tail star wheel toothed plate pushes the trolley to run forwards, a front working surface of the toothed plate is in contact with a trolley rear wheel sleeve and generates a thrust Fz which enables the trolley to move towards a tangent plane, the force has a force Fd towards the horizontal direction 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 rear wheel of the trolley can be lifted upwards, the star wheel continues to rotate, and at the moment when the trolley clamping wheel leaves the toothed plate, the front end of the rear trolley is in contact with the toothed plate and tightly extrudes to enable the front end of the rear trolley not to fall to the rail. By the circulation, each trolley is subjected to the stress process, so that the trolley on the return track generates a shoulder-building arching phenomenon. Two ways are usually adopted to solve the problem of arching of the trolley in the prior art. Firstly, a special boss rail is adopted, the running track is locally changed, 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 trouble, long replacement time and high cost; secondly, fixed rail pressing is adopted, the method is realized by forcibly pressing the trolley under the condition that the friction force is not eliminated, the method causes the abrasion of the end of the trolley to be intensified, a triangular groove is formed, the air leakage of the trolley is caused, the production is reduced, the correction is not thorough, the trolley still has arching of different degrees, the load of a motor is increased, the motor is damaged, the rack of a sintering machine and the track of the trolley are damaged, and the accidents such as the derailment of the trolley are caused.

Deviation: the reason for the trolley deviation is mainly because in the production and use processes, the metal material is deformed due to the influence of long-term thermal loads on the rack, the air box, the head and tail transmission wheels of the rail and the like, and the original installation precision is damaged under the combined action of factors such as uneven settlement of a plant foundation and the like, so that the trolley is deviated in operation. The deviation of the trolley can cause a plurality of adverse effects on the equipment and the production, such as: the service life of the wheels and inner cavity parts of the trolley is shortened, the travelling track of the trolley is abraded and displaced, the running state of the head and the tail of the trolley is abnormal, the abnormal running state of the head and the tail of the trolley can cause deformation of relevant components of a curve, meanwhile, the deformation can aggravate the deviation of the trolley, the vicious circle is continued until the trolley is separated from the travelling track, and after the trolley is separated from the travelling track, a large amount of time is needed for repairing and recovering equipment, so that the production rhythm is seriously influenced.

The intelligent management system of the sintering machine trolley generally provides the running state management of the sintering machine trolley through the modes of video identification, laser ranging, rail weighing and the like, but is limited to the early warning function, manual operation is needed for adjustment and intervention when the system judges that the sintering machine trolley has arching and deviation phenomena, and the arching and deviation phenomena cannot be automatically eliminated.
