Abstract
The utility model discloses a high-intensity disc-shaped hobbing cutter, which comprises an upper end cover and a lower end cover, two groups of bearings, cutter bodies, a cutter ring, a center seat and a plurality of uniformly distributed screws, wherein the upper end cover and the lower end cover are arranged at two ends of a cutter shaft, the two groups of bearings, the cutter bodies and the cutter ring are sequentially arranged on the cutter shaft between the two end covers in the radial direction, the center seat is arranged between the two cutter bodies, and the uniformly distributed screws are connected with the upper end cover and the cutter shaft. The high-intensity disc-shaped hobbing cutter is characterized in that the center of the upper end cover is provided with a cylinder protruding in the direction towards the cutter shaft, and the cutter shaft is provided with a cylinder groove tightly matched with the cylinder. The high-intensity disc-shaped hobbing cutter solves the problem that the abnormal damage of the hobbing cutter is caused by the fact that the looseness, the deformation and the failure are easily generated under the external force impact due to the poor connecting intensity between the cutter shaft of a center hobbing cutter and the upper end cover during the construction of a shield machine.
Description
Technical field
The utility model relates to a kind of high-intensity disk cutter, mainly is applicable to shield machine supporting cutter when tunnel piercing.
Background technology
Shield machine construction has advantages such as mechanization degree height, speed of application height, safety height, is widely used in the tunnel piercing of Important Project such as subway, railway, water power.Shield machine full section hard rock construction or on during soft down hard compound stratum construction, adopt disk cutter more, the disk cutter cutter ring is pushed down into rock mass in shield machine thrust and makes catalase during work.Disk cutter not only bears very big radially broken rock power as rock crushing tool, receives reverse shearing force of rock and frictional force simultaneously again, and the anti-impact force whole to hobboing cutter requires very high.The strength of materials of cutter hub, end cap, cutter shaft with and the mutual mode that is linked and packed all influence the whole impact resistance of hobboing cutter.
Shield machine is used disk cutter at present, and its cutter shaft center is provided with the center mounting hole that a protruding round platform passes upper end cover, and thin upper end cover adopts bolt to be connected with cutter shaft; Be prone under the external impacts produce distortion, connect and become flexible; Cause the hobboing cutter overall structure loose gradually, finally cause general assembly sealing and bearing failure, make hobboing cutter occur cutter ring displacement, eccentric wear easily; Even integral body falls apart, and causes improper damage.
Summary of the invention
The utility model will solve when being shield machine construction, and the bonding strength of center hobboing cutter cutter shaft and upper end cover is poor, is easy to generate loosening, deformation failure under the external impacts, and then causes the problem of the improper damage of hobboing cutter.
For addressing the above problem; The high-intensity disk cutter of the utility model comprises the upper end cover, the bottom end cover that place the cutter shaft two ends, two groups of bearings, cutter hub and cutter rings radially arranging successively between two end cap, on the cutter shaft; Centre mount between two cutter hubs; And the some screws that are uniformly distributed with that connect upper end cover and cutter shaft, it is characterized in that: said upper end cover center has a cylinder to the cutter axis orientation protrusion, and cutter shaft has and the close-fitting cylinder groove of said cylinder.
The utility model will have the cutter shaft installing hole cancellation on the disk cutter upper end cover now; And the cylinder to cutter axis orientation protrusion is set on this position; Cutter shaft has corresponding cylinder shape groove, through bolt upper end cover is fixedly connected with cutter shaft again, and this structure relates to the intensity that has not only increased upper end cover; Also strengthen the bonding strength of cutter shaft and upper end cover, improved whole anti-impact force of hobboing cutter and application life; Cutter shaft does not stretch out upper end cover, is embedded in the upper end cover simultaneously, has improved the hobboing cutter sealing performance.
Description of drawings
Fig. 1 is the structure sectional view of the utility model.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is an A enlarged diagram among Fig. 1.
Fig. 4 is existing disk cutter structure sectional view.
The specific embodiment
Below in conjunction with specific embodiment and accompanying drawing 1-3 the utility model is described further.
Shown in Fig. 1-3; The high-intensity disk cutter of the utility model; Comprise the upper end cover 1, the bottom end cover 7 that place cutter shaft 2 two ends, the centre mount 5 between two groups of bearings 8, cutter hub 6 and 4, two groups of cutter hubs of cutter ring of radially arranging successively between two end cap, on the cutter shaft 2; Upper end cover 1 center has cylinder 11 to cutter shaft 2 directions protrusion, and 2 of cutter shafts are designed with and this cylinder 11 close-fitting cylinder grooves 21.
With the centre mount 5 between bottom end cover 7, two groups of bearings 8, two cutter hubs 6, two cutter rings 4, two cutter hubs; Be installed in respectively on the cutter shaft 2; Then the cylinder 11 of upper end cover 1 is placed the cylinder groove of cutter shaft 2, the screw 3 through some circumference uniform distributions is fixedly connected upper end cover 1 with cutter shaft 2 again.The disk cutter that assembles, existing disk cutter shown in Figure 24 relatively, not only the intensity of upper end cover 1 has increased, and simultaneously cutter shaft 2 has also strengthened with the bonding strength of upper end cover 1, makes the whole anti-impact force of hobboing cutter and strengthening greatly application life; Cutter shaft 2 does not stretch out upper end cover 1, is embedded in the upper end cover simultaneously, has improved the hobboing cutter sealing performance yet.
