Abstract
The utility model provides a circular track under mining excavator, includes the roller of belt wheel shape boss, circular track be overall structure under the characterized by, is equipped with an annular groove in circular track's last plane centre down, in the annular boss roll of roller circular track's under the annular groove. Circular track's deformation reduces when adopting behind this technical scheme the roller on the circular track rolling in the plane under, it is more steady move, and the reduce the fault emergence has prolonged time circular track's life.
Description
Technical field
Under the utility model belongs to a kind of 15 cubic meter excavators, the reeded lower ring rail of tool in the middle of plane gone up by ring rail, particularly one.
Background technology
15 cubic meter excavators are one of a kind of main equipments of surface mining, and the dipper capacity of excavator is 15 cubic meters, mainly peel off open coal mine material, exploit.In excavator, lower ring rail is arranged in the upper plane of excavator lower device, and existing lower ring rail is made up of ring rail inner ring, locating piece, ring rail outer ring, fastening, bolt, nut etc.Ring rail inner ring and ring rail outer ring are placed on a horizontal plane side by side, the hole of the uniform n in ring trackside face processing, there is locating piece centre, respectively there is a fastening block two sides, locating piece and the middle hole having processing of fastening block, by bolt, ring rail inner ring, locating piece, ring rail outer ring, fastening block, packing ring are linked together, link into an integrated entity with after fastening nuts.During work, roller outer cylinder surface rolls above rolling ring device in the upper plane of lower ring rail is excavator upper unit, weigh more than 1000 ton, the back rotation during work of excavator upper unit, roller in rolling ring device repeatedly rolls in the upper plane of lower ring rail, roll, roller is in order to reconcile the distance of the centre of gyration and axial float, the side that the annular boss of roller clashes into ring rail inner ring and ring rail outer ring makes ring rail be out of shape, roll, redeformation, to roll carrying out repeatedly again, bolts and nuts are loosened, the width specified between ring rail inner ring and ring rail outer ring there occurs change, exacerbate the wearing and tearing of plane on ring rail, cause damaging, reduce the application life of lower ring rail.
Summary of the invention
The purpose of this utility model is to provide ring rail under a kind of 15 novel cubic meter mine excavators, roller on lower ring rail during plane rolling the distortion of ring rail reduce, motion is more steady, reduces fault and occurs, and extends the application life of lower ring rail.
The technical scheme that the utility model provides is as follows: the roller comprising band annular boss, is characterized in that: lower ring rail is overall structure, in the middle of the upper plane of lower ring rail, be provided with an annular groove, and the annular boss of roller rolls in the annular groove of lower ring rail.
Effect of the present utility model: to adopt after the technical program roller on lower ring rail during plane rolling the distortion of ring rail reduce, motion is more steady, reduces fault and occurs, extend the application life of lower ring rail.
