Description
Technical field
The utility model is related to a kind of band firming storehouse of shield machine, more particularly to a kind of shield machine cut when changing cutter
With the air exchange system on firming storehouse.
Background technology
Shield machine is on driving during soft lower hard compound stratum, and tool wear is typically than more serious, it is necessary to which periodically with pressure enter
Tu Cang, is checked and is changed to cutterhead and cutter.When cutter or serious girff deformation, it is impossible to use conventional method warehouse entry with pressure
When being changed, can only be got angry cutting method by warehouse entry with pressure, and the cutter of gross distortion is cut off.Because Tu Cang is needed
Stable pressure is kept, and in air-tight state.Band fire can produce smog when being cut to cutter, make closed with pressure
Tu Cang air deteriorates the people that chokes, and causes operating personnel can not stop operation.
The content of the invention
The utility model provides a kind of shield machine belt firming storehouse air exchange system cut when changing cutter, solves shield
Machine Tu Cang cutting deformation cutters of getting angry under air-tight state make air in storehouse deteriorate the technology that the people that chokes makes cutting work not carry out
Problem.
The utility model is to solve above technical problem by the following technical programs：
A kind of shield machine belt firming storehouse air exchange system cut when changing cutter, including cutter head of shield machine, shield machine Tu Cang
And air compressor, precut deformation cutter is provided with cutter head of shield machine, on the cutterhead of precut deformation cutter side
Foaming system inlet is provided with, ball valve is provided with shield machine Tu Cang native storehouse dividing plate, air compressor passes through air inlet pipe
It is connected together with foaming system inlet, escape pipe is connected with the ball valve on native storehouse dividing plate top, in the native storehouse of shield machine
It is provided with imderwater cutting device.
Hydraulic pressure cutter device is to complete the cutting to precut deformation cutter with fire.
The utility model becomes possibility using the cutter on the method quick-replaceable cutter head of shield machine of cutting, it is ensured that shield
The stable safety of the interval top soil body of structure, and saved the duration.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in detail below in conjunction with the accompanying drawings：
A kind of shield machine belt firming storehouse air exchange system cut when changing cutter, including cutter head of shield machine 1, shield machine Tu Cang
2 and air compressor 7, precut deformation cutter 3 is provided with cutter head of shield machine 1, the knife in precut deformation cutter 3 side
Foaming system inlet 4 is provided with disk 1, ball valve 6, air compressor 7 are provided with the native storehouse dividing plate 5 in the native storehouse 2 of shield machine
It is connected together by air inlet pipe 8 with foaming system inlet 4, escape pipe 9 is connected with the ball valve 6 on the native top of storehouse dividing plate 5,
Imderwater cutting device 10 is provided with the native storehouse 2 of shield machine.Hydraulic pressure cutter device 10 is that band fire is completed to precut deformation cutter 3
Cutting.The utility model solves the replacement proble of air in native storehouse, and keeps stable gas pressure in native storehouse.Selection and pre-cut
Cutter has nearest foaming system inlet as air admission hole, from native storehouse median septum top ball valve as steam vent, pass through
Ball valve in control foaming system and median septum replaces flow to adjust air, and it is reached stable equilibrium.Then water is selected
Lower burning torch, coordinates electrode for underwater cutting, enters in native storehouse, carries out cutting operation.
