Referring to Fig. 1 and Fig. 2, Fig. 1 and Fig. 2 provides a kind of specific embodiment of cutterhead of the present invention, wherein Fig. 1 is this hair
Structural schematic diagram when cutterhead hydraulic mandril disclosed in bright embodiment extends；Fig. 2 is the cutterhead disclosed in the embodiment of the present invention
Structural schematic diagram when hydraulic mandril shortens.
As depicted in figs. 1 and 2, the replacement of gate when cutterhead provided by the invention can very easily realize cutterhead repair.
The cutterhead includes cutterhead body 1, knife bar 2, cutter 3, gate 4, movable cylinder 5, ring flange 6, hydraulic mandril 7 and compression rod piece 8.
In the present solution, the cutterhead includes cutterhead body 1, cutterhead body 1 has been used for body supports effect, cutterhead body 1
Structure carries out selection design according to actual needs with size.
Knife bar 2 is inserted in cutterhead body 1, and cutterhead body 1 is to be flexibly connected 2 upper end of knife bar to be provided with knife with knife bar 2
Tool 3.Specifically, cutter 3 can be hobboing cutter or tearing cutter or cutter.
2 lower end of knife bar is arranged gate 4, movable cylinder 5 and ring flange 6 successively, and the top of movable cylinder 5 is located at 4 lower section of gate, ring flange
6 tops are located at the lower section of movable cylinder 5 and ring flange 6 and 2 detachable connection of knife bar.Gate 4 has been used to completely cut off face muddy water and has poured in
The effect of movable cabin.Movable cylinder 5 is for withstanding gate 4.Ring flange 6 is used to gate 4 and movable cylinder 5 being fastened on knife bar 2 together
On.
In this way, once gate 4 breaks down, the dismounting of above-mentioned detachable connection can be easily realized.Specifically,
With reference to hydraulic mandril 7 provided by the invention and the replacement process for compressing the detailed description gate 4 of rod piece 8.
In the present solution, being provided with hydraulic mandril 7 outside knife bar 2, hydraulic mandril 7 is for plaing a part of to hold out against knife bar 2.Hydraulic pressure
Be provided with the compression rod piece 8 that can be used for temporarily knife bar 2 being connected in cutterhead body 1 outside mandril 7.Certainly, hydraulic mandril 7 with
It compresses rod piece 8 itself and is not belonging to a part for cutterhead, the permanent organization being also not belonging to outside cutterhead.Hydraulic mandril 7 and compression
Rod piece 8 is general only to be needed just specially fetch from outside when gate 4 is replaced to be installed to below knife bar 2.
Specifically, when cutterhead works normally, cutterhead body 1 passes through gate 4, movable cylinder 5 with the connection of knife bar 2 between the two
And ring flange 6 is realized；When gate 4 needs replacing, cutterhead body 1 is with the connection of knife bar 2 between the two by the way that pressure is arranged temporarily
Tight rod piece 8 is realized.
In specific implementation process, when the cutterhead normally carries out scar driving, knife bar 2 by gate 4, movable cylinder 5 and
Ring flange 6, which is held out against, to be connected in cutterhead body 1.
When needing to carry out the replacement of gate 4, hydraulic mandril 7 first extends dieback in the lower section of knife bar 2, then removes method successively
Blue disk 6, movable cylinder 5, gate 4, and ring flange 6, movable cylinder 5, gate 4 is axially downward, until gate 4 is completely from knife
Bar 2 is detached from, and then will be compressed the connection of rod piece 8 and is supported between knife bar 2 and cutterhead body 1, then hydraulic mandril 7 of retracting is until hydraulic pressure
7 top of mandril and knife bar reserve enough replacement gaps between 2 lower section, then by old or bad ring flange 6, movable cylinder 5, lock
Door 4 takes out from the replacement gap location, and new or good ring flange 6, movable cylinder 5, gate 4 are set to hydraulic pressure from the replacement gap location
On mandril 7, then the elongation of hydraulic mandril 7 again dieback removed and compress rod piece 8, by new or good gate in the lower section of knife bar 2
4, movable cylinder 5, ring flange 6 are attached to 2 lower end of knife bar successively.
Generally speaking, the present invention has the advantages that：
(1), the present invention substitutes original whole welding type knife bar using knife bar and flange disk body fabricated structure, to dismounting
Gate brings great convenience.
(2), present invention design advantages of simple, can convenient, fast realizations gate replace or repair, improve construction efficiency；
(3), the present invention is not limited solely to replace gate, such as needs to change or maintenance cylinder, ring flange or sealing element are equally suitable
With.
In the present embodiment, to further facilitate matching between knife bar 2 and hydraulic mandril 7 and 7 top pressure of hydraulic mandril in knife
2 bottom of bar, it is preferable that 2 lower section of the knife bar is tubular guide rod, and can deeply extremely when the mandril elongation of the hydraulic mandril 7
The inner cavity of the tubular guide rod.
In the present embodiment, to further enhance the sealing of muddy water, it is preferable that be arranged between the gate 4 and the knife bar 2
There is sealing element 9.
In the present embodiment, for the detachable connection for further facilitating between gate 4 and knife bar 2, while facilitating ring flange 6
With the detachable connection between knife bar 2, it is preferable that be provided with connection bolt 10 between the gate 4 and the knife bar 2.Institute
It states and is provided with connection bolt between ring flange 6 and the knife bar 2.
In the present embodiment, to further facilitate the support of the interim connection between knife bar 2 and cutterhead body 1, it is preferable that described
It includes symmetrical left compression rod piece and right compression rod piece to compress rod piece 8.The left compression rod piece and the right compression rod piece
Top be provided with outside outer land and bottom is provided with inside interior land, the outer land can with the cutterhead body 1
It is detachably connected with, the interior land and 2 detachable connection of the knife bar.
The present invention also provides a kind of shield machine, which can be with the replacement of very convenient gate.On the shield machine
Cutterhead described in above-mentioned any one is installed.
A kind of cutterhead provided by the present invention and shield machine are described in detail above.It is used herein specifically a
Principle and implementation of the present invention are described for example, and the explanation of above example is only intended to help to understand the present invention's
Method and its core concept.It should be pointed out that for those skilled in the art, not departing from the principle of the invention
