Feature of the invention and other correlated characteristics are described in further detail by embodiment below in conjunction with attached drawing, with
Convenient for the understanding of technical staff of the same trade:
Such as Fig. 1-8, label 1-12 is respectively as follows: cutterhead shaft 1, the first cutterhead disk 2, the first cutterhead spoke 3, the first disk in figure
Drill the 4, first spoke drilling 5, bearing 6, the second cutterhead disk 7, the second cutterhead spoke 8, the second disk the 9, second spoke of drilling
Drill 10, spoke bolt 11, disk bolt 12.
Embodiment: as shown in figures 1-8, the present embodiment more particularly to a kind of changeable cutterhead aperture opening ratio mechanical device and its
Application method, the mechanical device include connecting another second cutterhead disk 7, the second cutterhead disk by bearing 6 in cutterhead shaft 1
Several second cutterhead spokes 8 identical with the first cutterhead spoke 3 of circumferentially-spaced fixation on 7, correspondence opens up on two cutterhead disks
Disk drills, also corresponding on spoke thereon to open up spoke drilling, passes through and changes the first cutterhead spoke 3 and the second cutterhead spoke 8
Circumferential relative position to realize the adjusting of cutterhead aperture opening ratio.
As shown in Figs. 1-2, the present embodiment is related to the existing cutterhead of shield machine comprising the first cutterhead disk 2 and the first knife
Disk spoke 3, on the circumferentially-spaced periphery for being fixed on the first cutterhead disk 2 of the first cutterhead spoke 3；Existing cutterhead is fixed on cutterhead and turns
On axis 1, i.e., the center of the first cutterhead disk 2 passes through cutterhead shaft 1 and is fixed thereon, and can revolve with the rotation of cutterhead shaft 1
Turn.It is circumferentially spaced on the first cutterhead disk 2 to be equipped with several first disks drilling 4, far from cutterhead on the first cutterhead spoke 3
The one end of shaft 1 offers several first spokes drilling 5, the axis of the axis of any first spoke drilling 5 to cutterhead shaft 1
Distance be equal.
As shown in Figure 3-4, the mechanical device of the changeable cutterhead aperture opening ratio in the present embodiment includes 7 He of the second cutterhead disk
Second cutterhead spoke 8, on the circumferentially-spaced periphery for being fixed on the second cutterhead disk 7 of the second cutterhead spoke 8；Second cutterhead disk 7
It is connected by bearing 6 with cutterhead shaft 1, specifically, 7 center of the second cutterhead disk offers through-hole, cutterhead shaft 1 is logical across this
Hole, and it is provided with bearing between the two, so that the second cutterhead disk 7 will not rotate with it when cutterhead shaft 1 rotates.?
It is circumferentially spaced on second cutterhead disk 7 to be equipped with several second disk drillings 9 corresponding with the drilling 4 of the first disk, second
Several second spoke drillings 10 corresponding with the drilling 5 of the first spoke are offered on cutterhead spoke 8, likewise, any second spoke
The distance of axis of axis to the cutterhead shaft 1 of item drilling 10 is equal, and the first disk drill the 4, first spoke drill 5, the
The axis of the drilling 9 of two disks and the second spoke drilling 10 is parallel with the axis of cutterhead shaft 1, so that it is guaranteed that the first cutterhead spoke
3 and second cutterhead spoke 8 in the case where partially overlapping, the first spoke of part drilling 5 drills with the second spoke of part 10 to be remained to
Alignment.
As viewed in figures 5-8, the front of shield machine is arranged in existing cutterhead in the present embodiment, and mechanical device is then arranged both
Have behind cutterhead, the quantity of the first cutterhead spoke 3 and the second cutterhead spoke 8 is equal, and shape is identical, in order to aperture and adjusts knife
Dish opening rate.
As viewed in figures 5-8, the application method of the mechanical device of the changeable cutterhead aperture opening ratio in the present embodiment is divided into following
Three kinds of situations:
(1) when having no need to change cutterhead aperture opening ratio, existing cutterhead is overlapped with this mechanical device, i.e. 3 He of the first cutterhead spoke
Second cutterhead spoke 8 is completely coincident so that the first disk drilling 4 on the first cutterhead disk 2 and second on cutterhead disk 7 the
Two disks drilling, 9 alignment, is then inserted by dismountable disk bolt 12 and is fixed, and the first spoke drilling 5
It is also aligned with the second spoke drilling 10, and is inserted and is fixed by dismountable spoke bolt 11；Due to the second cutterhead
Disk 7 is connected in cutterhead shaft 1 by bearing, therefore the first cutterhead disk 2 is with the second cutterhead disk 7 when the rotation of cutterhead shaft 1
Also it will be driven and rotate together by existing cutterhead, to not influence the normal excavation in cutterhead face.
(2) when needing to significantly alter cutterhead aperture opening ratio, disk bolt 12 and spoke bolt 11 are all removed, due to
Second cutterhead disk 7 by bearing be connected in cutterhead shaft 1 with cutterhead shaft 1 rotate, therefore can by existing cutterhead rotate compared with
Wide-angle (quantity of the angle and the first disk drilling 4 is related, and theoretically adjustable angle is N=360 °/n, N=1,2,
3 ... n are the number of the first disk drilling 4) so that the second disk bit on the drilling 4 of the first disk and the second cutterhead disk 7
Hole 9 is aligned, and then insertion disk bolt 12 is fixed wherein again, can significantly alter the cutterhead aperture opening ratio of shield；By
It is connected in cutterhead shaft 1 in the second cutterhead disk 7 by bearing, therefore existing cutterhead is with the second cutterhead when the rotation of cutterhead shaft 1
Disk 7 will also be driven by the first cutterhead disk 2 and be rotated together.
(3) when needing to change cutterhead aperture opening ratio by a small margin, disk bolt 12 and spoke bolt 11 are all removed, due to
Second cutterhead disk 7 by bearing be connected in cutterhead shaft 1 with cutterhead shaft 1 rotate, therefore can by existing cutterhead rotate compared with
Then low-angle is inserted into spoke bolt so that the first spoke of part drilling 5 is aligned with the second spoke of part drilling 10 wherein again
11 are fixed, and can change the cutterhead aperture opening ratio of shield by a small margin；Since the second cutterhead disk 7 is connected to cutterhead by bearing
In shaft 1, thus existing cutterhead with cutterhead shaft 1 rotate when the second cutterhead spoke 8 also will by the first cutterhead spoke 3 drive and
Rotation.
The beneficial effect of the present embodiment is: (1) without dismantling the i.e. changeable cutterhead aperture opening ratio of cutterhead, having flexible and efficient
Feature；(2) spoked shape can make change according to the cutterhead shape of different shields, and adaptability is stronger；(3) adjustable openings rate model
It encloses greatly, is suitable for Different Strata requirement.
