Description
Technical field
A kind of tunnel piercing away drill cuttings attachment means of the utility model, are related to one kind in tunnel piercing, driving are bored
The attachment means that head cutter is changed, belong to constructing tunnel field.It is more particularly to a kind of by screw thread and position limiting structure, realize
The attachment means of the quick dismounting and change of cutter.
Background technology
At present, when constructing tunnel is tunneled, the heading equipment used is mainly rock tunnel(ling) machine and coordinates other rock drilling
Machine, the drill bit used is all for based on entirety, by Welding of cutters on heading end, when wear occurs, it is necessary to cutter
Progress re-starts soldering processing, in work progress, and when running into the harder position of lithology, cutter is integrally broken, influence
Driving cutting balance, but the progress repairing time is longer, delays the duration, is made troubles to constructing tunnel.
Utility model content
In order to improve above-mentioned situation, a kind of tunnel piercing away drill cuttings attachment means of the utility model pass through there is provided one kind
Screw thread and position limiting structure, realize the attachment means of the quick dismounting and change of cutter.It is simple in construction, it is convenient and practical.
A kind of tunnel piercing away drill cuttings attachment means of the utility model are realized in：A kind of tunnel of the utility model
Drill bit tool attachment is made up of main body fixing device and auxiliary stopper device, and main body fixing device is by being screwed
Set, wedging face, cutter, cutter chuck, installation set, rear positive stop lug boss and driving tool rest composition, installation are placed on driving tool rest,
Positive stop lug boss is placed on installation set inwall afterwards, and screw thread is provided with the installation set outer wall, and cutter chuck is placed on rear positive stop lug boss,
And in installation set, the cutter chuck upper end is frustum cone structure, cutter is placed in cutter chuck, and the set that is screwed, which is spirally connected, to be put
In in installation set, described be screwed puts the wedging face of being equipped with, and the wedging face and cutter chuck are brought into close contact, auxiliary stopper dress
Put by fixing screws, fixing groove, connecting pin, gag lever post, arc clamp, sealing screw plug, rotation stop bayonet lock, front limit boss and connection
Set composition, adapter sleeve one end is placed on cutter chuck, and the external diameter of the adapter sleeve is less than rear positive stop lug boss internal diameter, and sealing screw plug is put
In in adapter sleeve, and fitted with cutter, the front limit boss is placed on adapter sleeve other end outer wall, is opened on the adapter sleeve
Limited location hole, one end of gag lever post is fixed on driving tool rest inwall by connecting pin, and positioned at installation set side, it is described spacing
Fixing groove is provided with bar, fixing screws are placed on driving tool rest, and corresponding with fixing groove, and arc clamp one end is placed in gag lever post
The other end on, rotation stop bayonet lock is equipped with the other end of the arc clamp, and corresponding with the spacing hole on adapter sleeve.
In use, when driving cutter generation abrasion is needed to change, spiral shell opens the set that is screwed, and be now screwed the wedge put
Tight face and cutter chuck be not in wedging, and cutter chuck loosening cutter then takes out cutter and changed, and new cutter is put into knife
Have in chuck so that cutter and sealing screw plug contact, be then threadably secured set and fix cutter chuck, complete cutter more
Change, when cutter vibrations cause not departing from cutter chuck, fixing screws are unclamped so that fixing screws and fixing groove are de-
From then rotatable connection is sold, and connecting pin drives arc clamp to rotate by gag lever post, rotation stop bayonet lock and connection on arc clamp
Set departs from, and then unclamps and is screwed set, cutter chuck is taken out, by external force or other method by cutter dismounting and change, institute
The design for stating sealing screw plug is to start supporting role to cutter, the design of the cutter chuck be for more preferable fixed cutting tool,
The design of the front limit boss and rear positive stop lug boss is that, in order to prevent cutter from retracting or moving forward, the design of the rotation stop bayonet lock is
In order to prevent cutter from rotating, when reaching tunnel piercing, the quick faster purpose of the cutter on Denver Nuggets drill bit.
Beneficial effect.
First, it is simple in construction, it is convenient and practical.
2nd, it is with low cost, it is easy to promote.
3rd, the replacing efficiency of drill bit cutter can be improved.
