Abstract
The utility model discloses an installation structure of an advance cutter for a shield machine, which comprises a cutter body and a box body. The cutter body penetrates out of a reserved groove of the box body from bottom to top and is fixed with a groove arranged on the inner wall of the box body in matching mode through a protrusion arranged at the lower portion of the cutter body. A fixing block is an L-shaped block body which is attached tightly to the cutter body from bottom to top to be inserted in the reserved groove of the box body, and the bottom is connected to the end of the cutter body through a bolt. The installation structure has the advantages of being simple in structure and convenient to dismount.
Description
Technical field
The utility model relates to a kind of shield machine cutter mounting structure, relates in particular to a kind of shield machine with the cutter mounting structure of going ahead of the rest.
Background technology
Cutter is the cutter that in advance cuts the soil body in advance, and it cut the soil body in advance before the cutting knife cutting soil body, with soil body cutting whole into sections, for cutting knife is created good machining condition; The cutting width of cutter is generally narrow than cutting knife in advance, and stock-removing efficiency is higher, adopts cutter in advance; Can significantly increase the flowability of the cutting soil body, reduce the moment of torsion of cutting knife greatly, improve the stock-removing efficiency of cutting knife; Reduce the abrasion of cutting knife, on the loose media stratum, especially the go ahead of the rest result of use of cutter of sand-pebble layer is fairly obvious.Common cutter in advance is made up of cutter hub and the alloy body that is installed on the cutter hub, changes in the tunnel in advance that cutter is very frequent, does not remove the cutter box and select directly to change the cutter of going ahead of the rest from cutterhead usually; But in advance cutter generally is to adopt bolton on the cutter box; Because condition is abominable in the restriction in space and the native storehouse, in case the thread damage on the cutter box can't be repaired, need whole cutter box be removed from cutterhead; Cutter brings difficulty to changing in advance for this, and dismounting is also very inconvenient.
The utility model content
The purpose of the utility model is to provide a kind of shield machine with the cutter mounting structure of going ahead of the rest, and has simple in structure and advantage easy accessibility.
The purpose of the utility model is to realize through following technical scheme:
A kind of shield machine is with the cutter mounting structure of going ahead of the rest; Comprise cutter hub and box body; Said cutter hub passes the preformed groove of box body from the bottom to top, and fixes through the convexity of cutter hub bottom setting and the groove fit of inboard wall of cartridge setting, and said cutter hub passes through a fixed block jam-pack in the preformed groove of box body.
Said fixed block is a L shaped blocks, and is close to cutter hub from the bottom to top and inserts in the box body preformed groove, and the bottom is connected with the cutter hub end through bolt.
The rear and front end of said box body is provided with and is used for it is installed in the fixed end on the cutter head of shield machine, and right ends is welded with oblique back-up block.
The cross section of said fixed end can be triangle, quadrangle, hexagon or circular, has the box body installation on the said oblique back-up block and uses circular hole.
The beneficial effect of the utility model is: through cutter hub being passed from the bottom to top the preformed groove of box body; And the convexity that is provided with through the cutter hub bottom and the groove fit of inboard wall of cartridge setting are fixed; Use again a fixed block with the cutter hub jam-pack in the preformed groove of box body; Can accomplish installation, this mounting structure has simple in structure and advantage easy accessibility.
Description of drawings
According to accompanying drawing and embodiment the utility model is done further explain below.
Fig. 1 is the structural representation of the described shield machine of the utility model with the cutter mounting structure of going ahead of the rest.
Fig. 2 is that the A-A shown in Fig. 1 is to partial schematic sectional view.
Among the figure:
1, cutter hub; 2, box body; 3, convexity; 4, groove; 5, L shaped fixed block; 6, bolt; 7, fixed end; 8, oblique back-up block; 9, vertical circular hole; 10, horizontal circular hole.
The specific embodiment
In Fig. 1～2 illustrated embodiments, the described shield machine of the utility model mainly is made up of cutter hub 1 and box body 2 with the cutter mounting structure of going ahead of the rest; It is when assembling; Cutter hub 1 is passed the preformed groove of box body 2 from the bottom to top, and the convexity 3 that makes cutter hub 1 bottom be provided with is inserted in the groove 4 that box bodys 2 inwalls are provided with, and more L shaped fixed block 5 is close to the preformed groove that cutter hub 1 inserts box body 2 from the bottom to top; And its bottom connects cutter hub 1 through two bolts 6, and this mounting structure has simple in structure and advantage easy accessibility.
Be provided with through rear and front end and be used for it is installed in the fixed end 7 on the cutter head of shield machine at box body 2; The oblique back-up block 8 of right ends welding; Having box body 2 on the oblique back-up block 8 installs with horizontal circular hole 10 and vertical circular hole 9; Played the effect of fixing this mounting structure of convenience, the cross section of fixed end 7 is a hexagon in the present embodiment, and it also can be triangle, quadrangle or circular.
