Cutterhead retreat servicing unit.
Background technology
Tunneling shield method excavates the primary hand that Urban Underground construction is increasingly becoming by feat of the advantage of itself in the prior art
Section, shield, because the situation of tool changing often occurs in the abrasion of cutter, is tunneled, cutter is more in tunneling process in lithostratigraphy
Need to ensure that cutterhead and face there are enough gaps when changing, due to the abrasion of cutter, the knife up of new knife is higher than after abrasion
Cutter, therefore need to retract cutterhead when changing cutter, or face is manually dug out into a certain distance, it can pacify
Fill new cutter.Now due to many shield machines use active articulated shield machine, one of its advantage is exactly that can provide enough
Cutterhead setback force, it is ensured that cutterhead can be retreated, but in actual use because the frictional force for being hinged anterior shield body is big
In the frictional force for being hinged rear portion shield body, retreated if necessary to cutterhead, being then hinged rear portion shield body needs to provide enough frictional force.
Utility model content
The purpose of this utility model be to provide a kind of cutterhead suitable for active articulated shield machine retreat servicing unit with
Enough frictional force is provided to be hinged rear portion shield body.
It is auxiliary that technical solution of the present utility model is to provide a kind of cutterhead retrogressing suitable for active articulated shield machine
Device is helped, including is hinged rear portion shield body, it is characterised in that the upper left quarter and upper right quarter for being hinged rear portion shield body respectively sets one
Cutterhead retreats servicing unit, and the cutterhead, which retreats servicing unit, to be included being oriented to overcoat, oil cylinder and support boots, and the guiding overcoat is one
The sleeve of individual both ends open, guiding overcoat, which is fixed on, to be hinged in the shield body of rear portion, and the oil cylinder is fixed in guiding overcoat, the support
Boots are the cylinder of one end open, and support boots are enclosed on the outside of the piston rod of oil cylinder and are fixedly connected with piston rod, described to support the cylindrical of boots
Side face and it is oriented between the inner peripheral surface of overcoat and is provided with sealing device, the blind ends of oil cylinder support boots when stretching out is to overhanging
Go out to be hinged the outer circumference surface of rear portion shield body.
The sealing device is to be located at two circle sealing rings between the inner peripheral surface of the outer circumference surface of support boots and guiding overcoat.
The guiding overcoat, which is welded on, to be hinged in the shield body of rear portion, and the cylinder cap of the oil cylinder is bolted to be oriented to overcoat
On, the blind end of the support boots is bolted on the piston rod of oil cylinder.
The front portion for being oriented to overcoat is provided with flange, is oriented between the anterior flange of overcoat and the cylinder cap of oil cylinder provided with sealing
Enclose and be bolted.
Some steel nails are fixedly connected with the outside of the blind end of the support boots.
Compared with prior art, a kind of cutterhead suitable for active articulated shield machine of the utility model retreats servicing unit
With advantages below：1st, this assistant apparatus structure is simple, and the stretching or retraction of support boots are driven by the stretching of oil cylinder or retract,
When cutterhead is retreated, oil cylinder is stretched out, and in normal driving, oil cylinder is retracted, and the servicing unit, which is arranged in, to be hinged at the top of the shield body of rear portion,
In cutterhead fallback procedures, two fulcrums are added equivalent to shield body, is retreated for cutterhead and enough frictional force is provided, in addition should
Device is simple to operate, easy to maintenance, and security performance is high；2nd, guiding overcoat, which is welded on, is hinged in the shield body of rear portion, connection fastening, oil cylinder
It is bolted to put outside guiding, facilitates demolition and maintenance, support boots is bolted on the piston rod of oil cylinder, conveniently torn open
Unload maintenance；3rd, the front portion for being oriented to overcoat is provided with flange, is oriented between the anterior flange of overcoat and the cylinder cap of oil cylinder and is provided with sealing ring
And be bolted, it is ensured that oil cylinder is in the sealing being oriented in overcoat；4th, there is steel nail in support boots exterior design, reduce support boots
Abrasion.
