Description

Track lifting device for adjusting elevation of sintering machine track

Technical Field

The utility model relates to a track plays to rise ware for adjustment of sintering machine track elevation belongs to sintering equipment technical field.

Background

The sintering machine is the main body and core equipment of the whole sintering production line and bears the key task of sinter production. The trolley of the sintering machine continuously runs in a ring shape under the action of a transmission device, the rail belongs to a framework part of the sintering machine, wheels of the trolley run on the rail, and the rail bears the weight of the trolley and materials. After the mixture is loaded into a trolley of a sintering machine, the surface layer of the mixture forms a liquid phase tissue under the action of negative pressure after being ignited by an ignition furnace of the sintering machine, a series of physical and chemical reactions occur, and finally, the formed sintering ore with certain physical and chemical properties is discharged from the tail and enters the next procedure.

A series of devices and equipment for providing or generating negative pressure for the production of sinter are called air suction devices and comprise a travelling plate of a trolley, a sealing slideway, a dry oil lubricating system, a longitudinal beam, an air box, a flue, a machine head dust removal device, a main exhaust fan, a chimney and the like. The sealing slide way is one of key parts of the air suction device, is fixed on a longitudinal beam by an inner hexagon bolt, grease is beaten on the upper surface of the slide way by the grease through an oil pipe, the slide way is contacted with a moving plate of the trolley, the moving plate and the slide way are tightly pressed by a spring of the moving plate, the moving trolley and the static slide way form sealing, and therefore negative pressure is generated.

The service life of the slide is generally about 1.5 years, and when the slide is worn to a state that an oil groove is shallow and oil storage is difficult or a bolt cap is worn to a certain extent, the common sealing effect is reduced, and the slide needs to be replaced. In the service cycle of the slide, the rail is also worn to a certain extent, the wear is different from the head to the tail of the sintering machine, the lower part of the ignition furnace is generally burnt more, and the plastic deformation of the rail is more under the action of gravity. The longitudinal beam of the installation slideway also has certain buckling deformation in the vertical direction. Therefore, after the slide rail is periodically replaced, the elevation of the rail needs to be adjusted.

After the skids are installed on the longitudinal beams, the elevation is generally regarded as unchanged. The elevation of the track is generally adjusted by adding or subtracting an adjusting pad between the track and a track beam, and the conventionally adopted method is to tilt the track by a crowbar after loosening a pressing plate bolt of the track and add the adjusting pad. Taking a 265m2 sintering machine in a certain steel mill in Tangshan as an example, the effective length of the sintering machine is about 76 meters in the whole length of the sintering machine, wherein the total length of a head ignition furnace, a holding furnace, a mounting rail thereof, a tail sealing cover and the like is about 30 meters, which is nearly half of the total length, the space of the positions is limited, the use of crowbars is limited, certain dangers of bruising and crushing exist, the temperatures of the positions are high, the operation efficiency of maintenance personnel is low, sometimes, a gasket is biased, the upper surface of the rail is inclined during acceptance inspection, and the condition of rework occurs. These factors greatly affect the efficiency and quality of the overhaul. Therefore, aiming at the restriction of environmental factors of the slide replacement operation, the defects and limitations of the existing method are very necessary to design a novel track lifting device to ensure the reliability and maintenance efficiency of track lifting.
