Cold machine of ring with widen type upset platform truck

Technical Field

The utility model belongs to the technical field of the cold machine of ring, specifically be a cold machine of ring with widen type upset platform truck.

Background

The ring cooling machine is a ring cooling machine for short and is mainly used for cooling sinter unloaded from a sintering machine, the traditional ring cooling machine is mainly of a blast type, the front part of a trolley is connected with a triangular beam through a hinged support, wheels of the trolley move downwards along a curved rail during unloading, at the moment, because the horizontal height of the connection part of the front part and the hinged support is unchanged, tipping moment is generated to realize unloading, rubber and a ring sealing plate are arranged at the lower part of the trolley, sealing is realized by pressing the rubber and the sealing plate during the movement of the trolley, the ring cooling machine has the defects of high air leakage rate, low loading coefficient, easy abrasion of the curved rail and the like, and particularly after the ring cooling machine is used for a certain period, the problem is more and more obvious. The sealing surface of the rotary-arm type circular cooler is sealing rubber on the lower surface of the rotary frame and the upper part of the bellows, unloading is carried out by means of restraining the movement track of the rotary arm of the trolley through a pressing rail outside the trolley, the traditional defects are overcome, and most of owners select and transform the rotary-arm type circular cooler into the rotary-arm type circular cooler after the rotary-arm type circular cooler becomes the mainstream of the circular cooler at present and particularly the traditional circular cooler is used for a certain period of time.

At present, a commonly used rotary arm type trolley breast board of the circular cooler is close to the inner side of a rotary frame (ensuring smooth unloading of sintered ores), and the lower part of the rotary frame is provided with a supporting roll which is sealed in an annular mode. If need increase the platform truck width, then need to increase the distance between the cold quick-witted skeleton of ring inside and outside stand, however, to reforming transform the project, because the existence of former skeleton stand, the transformation space has been restricted, especially need increase cooling area increase production behind the cold machine transformation of part ring, how consequently rationally arrange the structure in effectual space in order to reach the production needs and seem especially important, in addition, because the interior windage of the cold quick-witted platform truck of ring is mostly middle height, both sides are low, cause both sides windage to be slightly little, the cooling effect is inhomogeneous.
