Abstract
The invention discloses a TBM (tunnel boring machine) cutter expansion and contraction device, which includes a cutter mounted at the front end of a TBM body, a cutter driving part mounted on the body and driving the cutter to rotate, and an expansion and contraction driving device mounted on the body and driving the cutter to move in the own rotating shaft direction. Due to the adoption of the technical scheme, when the TBM has a cutting tool change, the expansion and contraction driving device drives the cutter to advance and then contract, so that the TBM cutter expansion and contraction device effectively prevents a cutting tool from being stuck in a tunnel rock wall and bringing inconveniences to cutting tool replacement.
Description
Technical field
the present invention relates to a kind of cutter head of shield machine stretching device.
Background technology
shielding tunnel excavator, be called for short shield machine, a kind of special engineering machinery of tunnel piercing, with shield machine carry out tunnel construction have automaticity high, save that manpower, speed of application are fast, controllably face sedimentation when cavitation, weatherproof, excavation, do not affect the features such as water surface traffic when reducing the impact of above ground structure and excavating under water, the in the situation that, buried depth long at tunnel line being larger, with more economical rationality of shield machine construction.
when shield driving state, changeable type bite is to be inserted in rock stratum or earth, for convenience of tool changing, cutter need to be extracted from rock stratum or earth, depends merely on manpower and is difficult to reach.
Summary of the invention
in order to address the above problem, the object of the present invention is to provide a kind of cutter head of shield machine stretching device.
in order to reach above object, the technical solution used in the present invention is: cutter head of shield machine stretching device, it comprises and is installed on the cutterhead of shield machine body front end, the retractable driving device that is installed on body and drives cutter plate driver portion that cutterhead rotates, be installed on body and drive cutterhead to move along self rotor shaft direction.
further, retractable driving device comprises the brake cylinder of the sliding oil cylinder that several are evenly distributed along cutterhead circumference and the limit slippage oil cylinder stroke being connected with sliding oil cylinder.
further, retractable driving device is connected with cutter plate driver portion.
owing to having adopted technique scheme, cutter head of shield machine stretching device of the present invention, when being shield machine tool changing, retractable driving device is first advanced cutter plate driver cutterhead to shrink again, has effectively prevented the stuck inconvenience bringing for tool changing in tunnel crag of cutter.
Accompanying drawing explanation
accompanying drawing 1 is the structural representation of cutter head of shield machine stretching device of the present invention when cutterhead is positioned at reference position;
accompanying drawing 2 is the structural representation of cutter head of shield machine stretching device of the present invention when cutterhead is positioned at tool change position;
accompanying drawing 3 is cutter plate driver portion rear view in cutter head of shield machine stretching device of the present invention;
accompanying drawing 4 is tool changing step schematic diagram of the present invention.
number in the figure is:
1, body; 2, cutterhead; 3, cutter plate driver portion; 4, sliding oil cylinder; 5, brake cylinder.
The specific embodiment
below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
structural representation from accompanying drawing 1 to accompanying drawing 3 can be found out, the invention provides cutter head of shield machine stretching device, it comprises and is installed on the cutterhead 2 of shield machine body 1 front end, the retractable driving device that is installed on body 1 and drives cutter plate driver portion 3 that cutterhead 2 rotates, be installed on body 1 and drive cutterhead 2 to move along self rotor shaft direction.
retractable driving device is connected with cutter plate driver portion 3.Retractable driving device comprises sliding oil cylinder 4 and the some brake cylinders 5 being connected with sliding oil cylinder 4 that several are evenly distributed along cutterhead 2 circumference.In the present embodiment, each sliding oil cylinder 4 is connected with a brake cylinder 5.As shown in Figure 4, brake cylinder 5 is when braking, and its piston rod stretches out between the bottom of sliding oil cylinder 4 and the piston rod of sliding oil cylinder 4, and now the piston rod of sliding oil cylinder 4 can not shrink again, controls thus the stroke of sliding oil cylinder 4.
in accompanying drawing 1, when cutterhead 2 is positioned at reference position, between cutterhead 2 outer rim rear ends and shield machine body 1 front end, distance is L, L=150mm, in accompanying drawing 2, when cutterhead 2 is positioned at tool change position, distance L-s between cutterhead 2 outer rim rear ends and shield machine body 1 front end, L-s=50mm, s is the displacement of sliding oil cylinder 4, s=100mm.
from the step schematic diagram of accompanying drawing 4, can find out a kind of cutter replacing method that utilizes above-mentioned cutter head of shield machine stretching device:
1, after cutterhead 2 stops operating, cutterhead 2 is positioned at reference position, and brake cylinder 5 is in on-position;
2, sliding oil cylinder 4 promotion cutterheads 2 advance 20mm to crossover position from reference position along cutterhead 2 rotor shaft direction;
3, brake cylinder 5 is cancelled braking;
4, sliding oil cylinder 4 drives cutterhead 2 to shrink 120mm along cutterhead 2 rotor shaft direction again, and cutterhead 2 continues to be contracted to tool change position after being contracted to reference position; Operating personnel carry out tool changing;
5,, after tool changing finishes, sliding oil cylinder 4 promotes cutterhead 2 and advances 120mm to crossover position from tool change position;
6, brake cylinder 5 brakings;
7, sliding oil cylinder 4 drives cutterhead 2 to shrink 20mm to reference position, and now, under the effect of brake cylinder 5, sliding oil cylinder 4 can not shrink again.
above-described embodiment is only explanation technical conceive of the present invention and feature, and its object is to allow person skilled in the art can understand content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences that Spirit Essence is done according to the present invention change or modify, within all should being encompassed in protection scope of the present invention.
