Abstract
The utility model relates to a disk positive hobbing cutter device of a shield machine, which comprises a cutter shaft, an end cover, a cutter body, a cutter ring, bearings, a floating sealing ring, a compression ring and screws. At least two groups of the bearings are arranged in the middle of the periphery of the cutter shaft; the cutter body is arranged on the outer sides of the bearings, and the cutter ring is arranged at the middle on the outer side of the cutter body; the end cover is arranged at one end of the bearings; the compression ring is arranged on the other end of the bearings; the floating sealing ring is arranged between the bearing and the compression ring; and the end cover and the compression ring are fixed on the cutter body through the screws. The device has the advantages of sufficient strength, good wear resistance, long service life and the like, is convenient to maintain, replace and seal, and can be stably operated under broad geologic conditions.
Description
Technical field
The utility model relates to a kind of hobboing cutter device, relates in particular to the positive hobboing cutter device of a kind of shield machine dish type.
Background technology
High speed development along with China's modernization economic construction, the construction of tunnel building cause that with the subway is representative just is surging forward, as underground warehouse, water conservancy hole letter, large-scale tunnel engineering construction such as highway, railway tunnel, mine laneway are more and more, and just increasing towards diameter, mileage direction more and more longer, that quality requirement is more and more higher develops, and these actual national conditions that are China has a large population and a few land determine.The shield driving construction method is widely used in the tunnel construction, and not only efficient height, safety are good for it, and economic environmental protection, is the optimal selection of modern tunnel engineering construction, and the shield excavation machine go-go professional equipment that is it.Disk cutter is the dedicated tool that is used for rock cutting and soil layer on the shield excavation machine, it be installed on the cutterhead and when constructing tunnel the disk cutter cutter ring by in the injection rock soil layer, cutterhead drives disk cutter and realizes revolution and rotation under whirligig drives simultaneously, make hobboing cutter roll extrusion continuously on the rock soil layer, finish continuous cutting and fragmentation to the rock soil layer, therefore the cutter ring of disk cutter is in shield machine and lithostratigraphy position, contacted forefront, the load of bearing in work progress changes with the variation on stratum, variation to geological conditions has very high sensitiveness, so the length of cutter life and the compliance of geological conditions become one of key factor that influences shield machine construction efficient.
At present, " the positive hobboing cutter of dish type; its frame mode is generally at the part of being installed on it on the cutter shaft and makes from the mode that an end penetrates assembling; the sealed at both ends and moment of torsion of hobboing cutter can not be adjusted separately; shortcomings such as the wear-resisting amount of cutter ring is few, these positive hobboing cutters run into bad ground and the short and seal failure leakage of oil of cutter ring quick abrasion life-span easily takes place cause shortcomings such as cutter lost efficacy in advance that adopts 17 more than the positive hobboing cutter of home and abroad shield machine dish type.
The utility model content
The utility model provides a kind of shield machine dish type positive hobboing cutter device for solving the existing above-mentioned technological deficiency of the positive hobboing cutter of shield machine dish type both domestic and external.
The utility model is to be made of cutter shaft, end cap, cutter hub, cutter ring, bearing, floating sealing ring, pressure ring, screw; The technical scheme of the utility model technical solution problem is: cutter shaft periphery middle part is provided with at least two group bearings; Bearing arranged outside cutter hub, the outer middle side part of cutter hub is provided with cutter ring; Bearing one end is provided with end cap, and the other end is provided with pressure ring; Between bearing and the pressure ring floating sealing ring is set; End cap, pressure ring by screw on cutter hub.
The beneficial effects of the utility model: the positive hobboing cutter device of a kind of shield machine dish type that the utility model provides, sufficient intensity is arranged, abrasion resistance is good and characteristics such as long service life, and can be under wide in range geological conditions steady operation.
Description of drawings
Fig. 1 is the positive hobboing cutter apparatus structure of a shield machine dish type schematic diagram.
Among the figure: cutter shaft 1, end cap 2, cutter hub 3, cutter ring 4, bearing 5, floating sealing ring 6, pressure ring 7, screw 8.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
As shown in Figure 1, cutter shaft 1 periphery middle part is provided with at least two group bearings 5; Bearing 5 arranged outside cutter hubs 3, cutter hub 3 outer middle side parts are provided with cutter ring 4; Bearing 5 one ends are provided with end cap 2, and the other end is provided with pressure ring 7; Between bearing 5 and the pressure ring 7 floating sealing ring 6 is set; End cap 2, pressure ring 7 are fixed on the cutter hub 3 by screw 8.
