Description
Technical field
The utility model relates to a kind of shield machine, relates in particular to the compound two initiatively articulated mountings of a kind of shield machine.
Background technology
Shield machine is the special engineering that is used to the tunnel machinery in a kind of constructing tunnel, and shield duct piece is the main mounting structure of shield-tunneling construction, is the outermost layer barrier in tunnel, is bearing the effect of resisting soil layer pressure, groundwater pressure and some special loads.The shield duct piece quality is directly connected to the total quality and the safety in tunnel, influences the water resistance and the endurance quality in tunnel.
Usually shield machine is because the stressed off-centre of PF cylinder pressure and section of jurisdiction, so that the section of jurisdiction is stable bad, and also fragile section of jurisdiction is especially when tight turn radius is constructed.Through using hinged propelling shield machine, make the section of jurisdiction consistent with the axis of PF cylinder pressure, the difficulty of construction in the time of can reducing the tunnel tight turn radius has increased the controllability of attitude of shield machine, thereby has protected the section of jurisdiction.
The utility model content
The purpose of the utility model is to provide a kind of shield machine compound two initiatively articulated mountings, for overcoming the problem that the passive articulated mounting of shield machine of the prior art causes the section of jurisdiction to break easily.
The purpose of the utility model realizes through following technical scheme:
The compound two initiatively articulated mountings of a kind of shield machine; Comprise cutterhead, Tu Cang, anterior shield, middle shield, backing; Hinged oil cylinder connects anterior shield and middle shield, middle shield and backing, is fixed with frame on the backing, and duct piece assembling machine is installed on the frame; Be provided with the PF cylinder pressure on the frame; Be provided with bulb on the PF cylinder pressure cylinder body, said bulb is placed in the bearing that is provided with Baltimore groove, is installed with on the bearing can bulb be tightened the baffle ring that in the bearing Baltimore groove, also can keep bulb freely to rotate; The front portion of cylinder bar is provided with eccentric disk, is welded with spherical top on the eccentric disk, and spherical top tightens it in having the bearing of Baltimore groove through baffle ring, is fixed with nylon sheet before the bearing; The hydraulic cylinder body that is positioned at the middle part can be fixed on the backing, and is enclosed within on the axle sleeve.
The beneficial effect of the utility model is: owing to be provided with bulb on the advancing hydraulic pressure cylinder body; Said bulb is placed in the bearing that is provided with Baltimore groove; Be installed with the baffle ring that can bulb tightened in the bearing Baltimore groove and can keep bulb freely to rotate on the bearing, thereby the formation articulated structure is fixed as one owing to bearing and middle shield again; The PF cylinder pressure receive force direction axial consistent with the section of jurisdiction all the time, protected the section of jurisdiction not receive the extruding of eccentric force well.
