Description
Technical field
The utility model belongs to the technical field of mine power shovel device maintenance, particularly relates to a kind of progressive wedging type central shaft limit stoper.
Background technique
The central shaft of power shovel equipment is the vitals that fixing top rotating platform and lower fixed stage also play certralizing ability, in former design, central shaft is after penetrating lower fixed stage central shaft hole by top rotating platform central shaft hole, its underpart nut carries out be tightened (that is to say that central shaft is equivalent to a large-sized bolt and top rotating platform and lower fixed stage is connected in series and fixes with nut), because power shovel is in digging operation process, top rotating platform and central shaft want locking phase to be in rotary motion for lower fixed stage, therefore be on center shaft along position in the past, the limit method adopting power shovel top rotating platform to be welded with square buting iron is fixed spacing to central shaft, to ensure that central shaft and top rotating platform are in compact siro spinning technology, thus reach the object of synchronous rotary, but due to central shaft, top rotating platform and lower fixed stage three are in assembly process, central shaft needs from upper, pass to complete assembling between lower fixed stage, also to ensure simultaneously, lower fixed stage mutually move rotate object, between the central shaft copper sheathing hole three of therefore central shaft and top rotating platform and lower fixed stage axially with radial while ensureing Spielpassung, rotate in digging operation process at power shovel between three, at the kinetic friction that axis and radial direction all will occur, first this kind of friction be cause the spacing buting iron of central shaft being welded on top rotating platform to wear and tear, along with the continuous expansion of buting iron wear extent, between central shaft and top rotating platform, movement clearance diametrically also strengthens gradually, aggravate the wearing and tearing of spacing buting iron thus, simultaneously along with the increasing of central shaft movement clearance also brings wearing and tearing to top rotating platform central shaft hole, can only be processed by the mode changing the spacing buting iron of central shaft for this reason, each replacing all needs electric welding, the coordinating operation that the multiplex (MUX) such as gas welding and pincers worker plants, not only increase spare parts cost, too increase maintenance workload simultaneously, and key wastes time and energy owing to changing central shaft buting iron at every turn, when not processing in time, strengthen causing the mutual wear extent between central shaft and top rotating platform, this kind of hidden danger also will extend the wearing and tearing caused between rotary carrier roller and upper lower railway, not only technical difficulty is greatly but also costly for the top rotating platform central shaft hole simultaneously repairing wearing and tearing, therefore be necessary very much to improve central shaft limit stoper.。
Summary of the invention
The purpose of this utility model is to provide a kind of progressive wedging type central shaft limit stoper, adjustment is carried out to the buting iron of wearing and tearing fastening, to guarantee the synchronous rotary of central shaft and power shovel top rotating platform, reduce the wear extent of top rotating platform central shaft hole and the central shaft diameter of axle to greatest extent, improve the assembling standard between central shaft and top rotating platform, extend the life cycle of spare part.
The purpose of this utility model is realized by following technical proposals:
The utility model progressive wedging type central shaft limit stoper, comprise the axle head block being located at central shaft top, this axle head block is connected with the top rotating platform of power shovel equipment, it is characterized in that described axle head block is provided with spacing vertical plane, this spacing vertical plane is abutted against mutually with mobile voussoir, this moves voussoir and is abutted against mutually with spacing buting iron, described mobile voussoir is also abutted against mutually with push bolt, this push bolt is threaded with internal thread fixed base, and this internal thread fixed base and described spacing buting iron are all fixed on described top rotating platform.
Described spacing buting iron is provided with sliding bevel, and described mobile voussoir is slidably connected with described spacing vertical plane and described sliding bevel respectively.
Described push bolt is provided with locking nut, and this locking nut is abutted against mutually with described internal thread fixed base.
The utility model has the advantages that:
The utility model fabrication and installation are easy, flexible operation, by implementing and Promotion practice, not only effectively ensure that the assembling standard of central shaft and top rotating platform, also reduce the maintenance workload that workman is daily simultaneously, while elongation center's axle and power shovel top rotating platform life cycle, also save the cost of equipment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the plan view of the utility model Fig. 1.
Embodiment
Embodiment of the present utility model is further illustrated below in conjunction with accompanying drawing.
As Fig. 1, shown in 2, progressive wedging type central shaft limit stoper of the present utility model, comprise the axle head block 1 being located at central shaft 4 top, this axle head block 1 is connected with the top rotating platform 7 of power shovel equipment, it is characterized in that described axle head block 1 is provided with spacing vertical plane 1-1, this spacing vertical plane 1-1 is abutted against mutually with mobile voussoir 2, this moves voussoir 2 and is abutted against mutually with spacing buting iron 3, described mobile voussoir 2 is also abutted against mutually with push bolt 6, this push bolt 6 is threaded with internal thread fixed base 5, this internal thread fixed base 5 and described spacing buting iron 3 are all fixed on described top rotating platform 7.Number in the figure 8 is lower fixed stage, and this lower fixed stage 8 is slidably connected with top rotating platform 7.
Described spacing buting iron is provided with sliding bevel, and described mobile voussoir is slidably connected with described spacing vertical plane and described sliding bevel respectively.
Described push bolt 6 is provided with locking nut 6-1, and this locking nut 6-1 is abutted against mutually with described internal thread fixed base 5.
Along with constantly carrying out of power shovel digging operation, the appearance wearing and tearing more or less of above-mentioned each parts, once generation gap or mobile voussoir 2 loosen, just rotatable push bolt 6, promotes mobile voussoir 2 and moves, until all parts is closely abutted against.In manufacturing the surface hardness relative limit buting iron of mobile voussoir 2 and axle head block 1 surface hardness smaller, make mobile voussoir 2 become easily damaged parts in the utility model, can regularly replace.In daily power shovel digging operation process, fastening by checking that the wear extent of mobile voussoir carries out carrying out adjustment to bolt timely, realize the stable operation of equipment.
