Description

Cutter head of shield machine auxiliary tool changing device in a kind of tunnel
Technical field
The present invention relates to shield machine technical field, cutter head of shield machine auxiliary tool changing device in more particularly, to a kind of tunnel.
Background technology
In shield-tunneling construction, due to distance tunneling construction when cutter can produce excessive wear, for preventing because of cutter Excessive wear, do not change in time and destroy cutter head structure, thus affecting project progress or producing security incident, this when is just Being necessary opens the cabin carries out inspection and the replacing of cutter.In the case that face self-stability is higher, can by grouting and reinforcing and The modes such as maintaining pile reinforcing carry out normal pressure and open the cabin.But cutterhead position is just closed on important building or is run into self-stable ability relatively sometimes During the stratum of difference, normal pressure tool changing of opening the cabin easily causes face and caves in even surface collapse, security risk greatly, now need into Row tool changing of opening the cabin with pressure.
But due to narrow space in the native storehouse after cutter head of shield machine, humiture is larger, ring when carrying out tool changing operation Border very severe, leads to dangerous during tool changing, and tool changing with pressure is even more great dangerous work.It is therefore desirable to developing one kind Underworker can carry out the device of tool changing that opens a position, to reduce working strength during workman's tool changing, improve work efficiency, reduce danger Dangerous coefficient.
Content of the invention
The technical problem to be solved in the present invention is, for the work of the tool changing of opening the cabin with pressure of cutter head of shield machine in prior art The drawbacks described above that intensity is big and risk is big, provides a kind of work that is simple, easy to use, can reducing during workman's tool changing of structure strong Spend, improve work efficiency and cutter head of shield machine auxiliary tool changing device in the tunnel of danger coefficient can be substantially reduced.
The technical solution adopted for the present invention to solve the technical problems is as follows:
In a kind of tunnel, cutter head of shield machine auxiliary tool changing device, including sealed compartment, telescoping mechanism and cutter clamping tool, stretches Contracting mechanism is placed in sealed compartment inside and is connected with cutter clamping tool;
Early gate and late gate are respectively equipped with the leading flank of sealed compartment and trailing flank;
Telescoping mechanism includes fairlead, the first executive component and the axis of guide;First executive component and the axis of guide are placed in leading To in the hollow cavity of set, and the first executive component left end is hinged with the fairlead end cap being arranged on fairlead left end, its right-hand member Hinged with axis of guide left end, and axis of guide right-hand member tilts to be hinged with the second executive component;
Cutter clamping tool includes hinged seat and the clamp assembly interconnecting;
Fairlead and the axis of guide are all located in inside sealed compartment, and axis of guide right-hand member and the second executive component are all and hinged seat Formed hinged.
In tunnel of the present invention, cutter head of shield machine auxiliary tool changing device includes sealed compartment, telescoping mechanism and cutter clamping work Dress, this telescoping mechanism is placed in sealed compartment inside and is connected with cutter clamping tool;Wherein, telescoping mechanism include fairlead, first Executive component and the axis of guide, the first executive component and the axis of guide are placed in the hollow cavity of fairlead, and the first executive component Left end is hinged with the fairlead end cap being arranged on fairlead left end, and its right-hand member is hinged with axis of guide left end, and axis of guide right-hand member inclines Tiltedly it is hinged with the second executive component;Cutter clamping tool includes hinged seat and clamp assembly;Fairlead and the axis of guide are all located in Inside sealed compartment, and axis of guide right-hand member and the second executive component all form hinged, structure very simple with hinged seat.
Carry out assisting the work flow of tool changing with pressure using cutter head of shield machine auxiliary tool changing device in tunnel of the present invention For:Shield machine stops driving, and tool changing operation group enters specified location, and soil sandstone around abrasion cutter etc. is cleared up, Now the early gate of sealed compartment and late gate are all closed, and telescoping mechanism shrinks, and telescoping mechanism and cutter clamping tool are all placed in In sealed compartment;Sealed compartment is carried out with pressurization makes pressure in sealed compartment consistent with pressure in native storehouse;Clear up around abrasion cutter After finishing, cutterhead is turned to the correspondence position of telescoping mechanism, opens early gate, telescoping mechanism extend out to abrasion tool position, Tool changing personnel dismantle worn-out cutter, and worn-out cutter are clamped in the clamp assembly of cutter clamping tool, telescopic machine In structure retraction sealed compartment, close early gate;Personnel open late gate out of my cabin, take off worn-out cutter from clamp assembly, and will New cutter is clamped in clamp assembly, closes late gate, and isobaric with native storehouse to carrying out in sealed compartment being forced in sealed compartment; Tool changing personnel open sealed compartment, control telescoping mechanism to extend out to correct position, tool changing personnel tighten new knife, and now, tool changing works Complete, easy to use.It follows that compared with tool changing step in prior art, using shield machine knife in tunnel of the present invention Disk assists tool changing device can not only reduce working strength during workman's tool changing, improve work efficiency, and is also greatly reduced evil The danger coefficient of shield machine tool changing under bad environment.
As one kind improvement to technical scheme of the present invention, early gate and late gate are located at fairlead and guiding respectively Axially two side positions of axle.Such design facilitates extravehicular operation personnel to be easy to open early gate and late gate, and will not with stretch Contracting mechanism interferes, and has further facilitated the use that cutter head of shield machine in described tunnel assists tool changing device.
As one kind improvement to technical scheme of the present invention, the first executive component is telescopic oil cylinder.First is executed Element is chosen as telescopic oil cylinder with thrust output and speed, thus realizing the reciprocating motion of the first executive component, that is, eliminates and subtracts Speed variator, and there is no drive gap, stable movement.
As one kind improvement to technical scheme of the present invention, the second executive component is oscillating oil cylinder.Second is executed Element is chosen as oscillating oil cylinder with output torque and angular velocity, has gathered very high moment of torsion in the space of very little, and convenient Carry out precise control.
As one kind improvement to technical scheme of the present invention, hinged seat includes mounting body, left articulated slab and right hinge Fishplate bar, and left articulated slab and right articulated slab are separately positioned on the left and right sides on mounting body top;
Clamp assembly is connected with left articulated slab and right articulated slab respectively by axle.
Above-mentioned left articulated slab and the setting of right articulated slab, not only facilitate the assembling of clamp assembly and hinged seat, but also The installation strength of clamp assembly and hinged seat can be ensured to a great extent.
As one kind improvement to technical scheme of the present invention, outside left articulated slab or right articulated slab, it is provided with reinforcement.
