Embodiment
In this specification, preceding is cutter head direction, is afterwards its opposite direction.
As shown in accompanying drawing 1-4, a kind of coke cutter, including inner sleeve 9, cutter head fixing pipe 91 is fixed in the front end of inner sleeve 9
Rear end, the front end of cutter head fixing pipe 91 is provided with fixing groove 93, and the cell wall of fixing groove 93 is provided with through hole 94, the free-swinging knife of fixing groove 93
First 10, the bearing pin 99 being hinged is passed through from through hole 94, angle >=90 ° for making cutter head 10 be rotated along bearing pin 99 to both sides.
Inner sleeve 9 and cutter head fixing pipe 91 are hollow, and inside both it wears push rod 8, the anterior end energy and cutter head of push rod 8
10 faces are contacted.
Push rod 8 stretches out, and coordinates in the rear end by inner sleeve 9 in the screw thread of inner sleeve 9, is outwards continuing and extend to
The rear of inner sleeve 9, push rod rotary part is provided with the rearward end of push rod 8.
Rotating turret 3 is fixed in the outer surface of inner sleeve 9.Rotating turret 3 can be with hand-turning, can also machinery drive rotation.
In order to reduce axial movement of the cutter head 10 along bearing pin 99, cutter head 10 coordinates with the gap of fixing groove 93.
Fixation of the push rod 8 to cutter head 10 for convenience, the front end face diameter of push rod 8 is more than the diameter of bearing pin 99.
For the ease of observation cutter head 10 position, the outer surface fixed angle staight needle 4 of inner sleeve 9, angle staight needle 4 and cutter head 10 are flat
Row and the same side for being located at inner sleeve 9.
For the fixation to cutter head 10 of swing of the front end in cutter head fixing pipe 91, influence of smaller push rod 8, push rod 8 with
The gap of cutter head fixing pipe 91 coordinates.
For the friction of smaller push rod 8 and inner sleeve 9, the internal diameter of inner sleeve 9 is more than the internal diameter of cutter head fixing pipe 91, both
Taper transition（Referring to Fig. 2 reference 92）.Passing through for cutter head is easy in taper transition.
In operation, burner does not stop working, and the application is through in the central tube of burner, in inner sleeve 9 and central tube
Between have space, in the outer surface stationary positioned flange 6 of inner sleeve 9, the distance of locating flange 6 to tool section 10 and the center of burner
The length matching of pipe 7, the rear end flanges of locating flange 6 and central tube 7 are connected, for convenience the axial rotation of inner sleeve 9,
Thrust bearing 5 is provided between inner sleeve 9 and locating flange 6.When central tube 7 is longer, inner sleeve 9 can occur in central tube 7
Flexible deformation, therefore, inner sleeve 9 is provided with least one circumferential support 71, circumferential support in the outer surface for entering the part of central tube 7
71 lateral surface is provided with lubricating oil, reduces the friction of circumferential support 71 and central tube 7.
Push rod 8 and the screw thread of the rearward end of inner sleeve 9, which coordinate, is specially：The outer fixed locking sleeve 2 of push rod 8, locking sleeve 2 with
The screw thread of inner sleeve 9 coordinates.
The push rod rotary part of the rearward end of push rod 8 is handwheel.
In use, first adjustment angle staight needle 4 downwards, then by the axial direction of cutter head 10 and inner sleeve 9 is adjusted to unanimously（I.e. cutter head to
Before）, inner sleeve 9 and cutter head 10 are put in central tube 7, when the rear end flange contact of locating flange 6 and central tube 7, cutter head
10 pass cutter head fixing pipe 91 and depart from cutter head fixing pipe 91, can rotate freely, it is because gravity, cutter head is swung to
Downward state.Two flanges are fixed.
Rotation hand wheel 1 drives push rod 8 to rotate again, push rod 8 is occurred relative motion with inner sleeve 9, until the front side end of bar 8
Portion is contacted with the face of cutter head 10, then tightens locking sleeve 2.Then, the fixation of push rod 8 and inner sleeve 9 is completed.Now, because top
Bar 8 blocks the unique free degree of cutter head 10（It is exactly the rotation along bearing pin 99）, also just complete a fixing pipe 91, cutter head 10
It is fixed.
Finally, craft or mechanical rotation rotating turret 3, drive inner sleeve 9, push rod 8, cutter head fixing pipe 91, cutter head 10 same
Step rotation, the rotational energy of cutter head 10 completes coke cleaning operation.
After the completion of coke cleaning operation, locking sleeve 2 is first unclamped, handwheel 1 is reversely rotated and drives push rod 8 away from cutter head 10, then pine
Two flanges are opened, the application is extracted out.
Above-described is only preferred embodiment of the present utility model, it is noted that for those skilled in the art
For, under the premise of the utility model general idea is not departed from, some changes and improvements can also be made, these should also be considered as
This practicality.
