Pulp-water.Starting two hydraulic cylinders 14 makes its synchronous, and space is provided to lift new hobboing cutter；
3) worn-out work hobboing cutter 11B is removed (such as together with its work tool apron 10B from along tilt axis OA by removing
Fig. 8), it lifts new hob assembly and puts into tool apron hole 15；
4) exchange sealing element 9 in sealed bladder 23 be depressurized after, start oscillating motor 6, make rotating device 2 using OA for turn
Moving axis rotates 180 °, and worn-out spare hobboing cutter 11A is moved into housing 1, screws out to tunnel and opens with stylish work hobboing cutter 11B
At the position of oral pore 4；
5) according to above-mentioned steps 3) worn-out spare hobboing cutter 11A is torn open together with its working standby tool apron 10A by removing
Under, it lifts new hob assembly and puts into tool apron hole 15；
6) finally, exchange sealing element 9 is pressurized and the peripheral contact with spare tool apron 10A, two hydraulic cylinders 14 are same again
When extend to plug 18 be inserted into tapered sleeve 17 in, open the first electrical ball valve 16A and the second electrical ball valve 16B make linear type mud arrange
Casing 12 is put to resume work.
To sum up, the utility model makes each tool apron hole increase a spare rolling using a rotating device simple in structure
Knife, and excavation face reaction force can be reliably born, and spare hobboing cutter switching can be completed by rotating automatically in a short time
Action, the concentration for realizing hobboing cutter are replaced, and are not only increased the continuity of construction, are also reduced the number of maintenance down, effectively
Ground improves shield machine construction efficiency；Treat that shield machine driving to the region suitable for tool changing operation, can carry out normal pressure tool changing, avoid
Staff enters operations involving high pressure environment, has not only ensured the personal safety of construction personnel, but also saves construction personnel and change and be pressed into cabin
Time, it is convenient and efficient.
Although the utility model is described above in conjunction with attached drawing, the utility model is not limited to above-mentioned
Specific embodiment, above-mentioned specific embodiment is only schematical rather than restricted, the ordinary skill of this field
Personnel, in the case where not departing from the utility model aims, can also make many variations under the enlightenment of the utility model, this
It belongs within the protection of the utility model a bit.
