Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. It will be appreciated by those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
According to the figure, the retainer ring 2 is assembled in a retainer ring groove 1.1 of the cutter hub 1 through a guide cone 3 in an annular shape, a transition taper part 3.2 with a small upper part and a big lower part is arranged at the upper part of the outer part of the guide cone, a stepped supporting part 3.3 and a limiting part 3.4 are continued on the transition taper part, the limiting part is assembled in an inner cavity of the cutter hub, the supporting part is pressed on the end surface of the cutter hub, the transition taper part is smoothly jointed with the guide taper part 1.2 at the end part of the cutter hub, and the conicity is consistent; the upper end in the guide cone is provided with a taking rod 3.1 for moving and carrying the guide cone.
The diameter of the limiting part is the same as the bore diameter of the inner cavity of the cutter hub and is in clearance fit with the bore diameter of the inner cavity of the cutter hub, and the height of the limiting part is smaller than the depth of the inner cavity of the cutter hub.
The lower diameter of the transition taper part is the same as the outer diameter of the guide taper part at the end part of the cutter hub, and the conicity of the transition taper part and the taper of the guide taper part are consistent with each other.
The taking rod is a hollow round pipe.
The utility model discloses a theory of operation:
the retaining ring adopted by the hob of the tunnel boring machine is usually of an open structure, the inner diameter of the hob ring is smaller than the diameter of the guide conical part of the cutter hub, and the hob ring can be embedded in the retaining ring groove of the cutter hub after being expanded. Because the inner diameter of the retainer ring is larger and the wall thickness is thick, the retainer ring is not easy to expand outwards and is not easy to be arranged in the retainer ring groove of the cutter hub under normal conditions. The utility model discloses a ring shape's cone, little big-end-up's transition pyramis in the cone continue have cascaded supporting part and spacing portion, the spacing portion assembly of cone lower part is at the inner chamber of sword hub, spacing portion diameter carries out radial positioning with sword hub inner chamber aperture clearance fit, the supporting part pressure of cone lower part carries out axial positioning on the terminal surface of sword hub, the lower part diameter in transition pyramis is the same with the outside diameter in the guide pyramis of sword hub tip, the taper in transition pyramis is unanimous with the conicity in guide pyramis. Therefore, the retainer ring sleeved on the transition cone portion in parallel moves downwards along the guide cone portion under the action of external force, the inner diameter of the retainer ring is increased along with the change of the diameter of the guide cone portion until the retainer ring falls into the retainer ring groove of the cutter hub, the cutter ring is fixed and limited, welding operation is carried out at a welding pool at the opening of the retainer ring to lock the cutter ring, and the cutter ring is assembled on the cutter hub.
The utility model has the characteristics that:
because the utility model discloses a toroidal shape cone lower part is equipped with spacing portion, spacing portion diameter and sword hub inner chamber aperture clearance fit, so the cover can be on the radial positioning of sword hub at the retaining ring in transition pyramis.
Because the utility model discloses a spacing portion in annular shape cone lower part continues there is the supporting part, and the supporting part pressure is on the terminal surface of sword hub, so the retaining ring of cover at transition pyramis can be at the axial positioning on the sword hub.
Because the lower diameter of the transition conical part is the same as the outer diameter of the guide conical part at the end part of the cutter hub, and the conicity of the transition conical part is consistent with that of the guide conical part, the retainer ring can move downwards along the guide conical part, and falls into the retainer ring groove of the cutter hub after being expanded by external force, and locks and fixes the cutter ring after the welding operation of the welding pool of the retainer ring, no gap exists among the retainer ring, the cutter hub and the cutter ring, and no relative displacement and vibration can be generated, so that the fatigue cracking and the welding falling off of the retainer ring are prevented.
Because the taking rod is arranged on the inner side of the guide cone body and used for carrying, the guide cone body is simple in structure, convenient and practical, and the working efficiency is improved.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit and the scope of the invention.
