Abstract
The utility model discloses a cutter retreating device of an articulated hard rock shield tunneling machine. The cutter retreating device of the articulated hard rock shield tunneling machine comprises an anchor rod drilling machine arranged in the rear body of the host machine of the articulated hard rock shield tunneling machine and an anchor rod, wherein the shell of the rear body of the host machine of the articulated hard rock shield tunneling machine is provided with an anchor rod hole. According to the cutter retreating device of the articulated hard rock shield tunneling machine, the whole work can be completed only by putting the anchor rod into rock layer through the anchor rod hole by using the anchor rod drilling machine and then utilizing devices on current articulated hard rock shield tunneling machine, so that the space required for replacing a new cutter can be rapidly and conveniently obtained, the time and the workload for replacing the cutter in a soil bin are saved, the risk for replacing the cutter in the hole is reduced, meanwhile the new cutter is avoided being damaged and thus economic losses of the enterprise are lowered.
Description
Technical field
The utility model relates to a kind of cutterhead setback device, relates in particular to a kind of cutterhead setback device of radial type hard rock shield structure.
Background technology
At present, the advantage such as shield construction is little to surrounding environment influence because having, speed of application is fast, quality project, construction safety environmental protection, geological adaptability are wide, becomes first-selected form of construction work in urban underground engineering construction.Along with shield structure stratum accommodation is extended gradually, the hard rock shield structure that is adapted to soft rock, middle hard rock geology arises at the historic moment.Compare hard rock mole, because of hard rock shield structure have advantages of cheap, geological adaptability is wide, is more suitable for municipal engineering construction of underground tunnel, underground engineering construction is widely used.
Using hard rock shield structure in the time that ground consisting of hard rock tunnels, cutter is because attrition needs often to change.In cutter changing process, because the cutter sword footpath of experience wear is relatively little, and embed in rock stratum, while more renewing cutter, need to there is certain cutter changing space.According to the conventional method, need first to remove from cutterhead back wearing and tearing cutter, then cut a pit at corresponding crag place, using this as more renewing the required replacing space of cutter.Because the cutter that whole cutterhead arranges is more, cause cutter changing longevity of service, workload large, in native storehouse, the activity duration extends, and brings greatly potential safety hazard.In addition, traditional cutter changing method is in the time of cutterhead initial rotation, and new edge and crag can form greater impact, tends to cause that new cutter damages, and has strengthened the economic loss of enterprise.
Utility model content
The purpose of this utility model is to provide a kind of cutterhead setback device of radial type hard rock shield structure, can utilize the equipment of existing radial type hard rock shield structure, body housing after fixing hard rock mole, retreat quickly and easily and obtain and more renew the required replacing space of cutter by the dilatory cutterhead of hinged oil cylinder, replacing cutter time, workload in native storehouse are saved, reduce in hole the tool changing risk property done strong, also avoided the damage of new cutter simultaneously, reduced business economic loss.
The utility model adopts following technical proposals:
A cutterhead setback device for radial type hard rock shield structure, comprises and is arranged on armature boring machine and the anchor pole in body after radial type hard rock shield machine main frame, after radial type hard rock shield machine main frame, on the housing of body, is provided with armature boring.
On described armature boring, be provided with shutoff cover plate.
Described shutoff cover plate is bolted on the housing of body after radial type hard rock shield machine main frame.
After described shutoff cover plate and radial type hard rock shield machine main frame, between the housing of body, be provided with sealing mat.
The utility model only needs to utilize armature boring machine to squeeze into anchor pole by armature boring to rock stratum, body housing after fixing hard rock mole, then utilize the equipment on existing radial type hard rock shield machine, retreat acquisition cutter changing space by the dilatory cutterhead of hinged oil cylinder and can complete whole work, can obtain quickly and easily and more renew the required replacing space of cutter, replacing cutter time, workload in native storehouse are saved, reduce in hole the tool changing risk property done strong, also avoid the damage of new cutter, reduce business economic loss simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of shutoff cover plate.
The specific embodiment
As depicted in figs. 1 and 2, the utility model comprises and is arranged on armature boring machine 7 and the anchor pole 8 in body 6 after radial type hard rock shield machine main frame, after radial type hard rock shield machine main frame, on the housing of body 6, be provided with armature boring 9, on armature boring 9, be provided with shutoff cover plate 11.Shutoff cover plate 11 is bolted on the housing of body 6 after radial type hard rock shield machine main frame.After shutoff cover plate 11 and radial type hard rock shield machine main frame, between the housing of body 6, be provided with sealing mat 12.
Existing radial type hard rock shield machine comprises body 6 after the articulated shield machine host precursor 4 that connects by hinged oil cylinder, articulated shield machine host.Articulated shield machine host precursor 4 comprises the pipe sheet assembling main beam that is connected in anterior cutterhead 3 and is connected in rear portion, is provided with hobboing cutter 2 on cutterhead 3, is provided with duct piece assembling machine reversing frame on pipe sheet assembling main beam.In the time that articulated shield machine need to carry out cutter changing, first keep hinged oil cylinder to there is certain overhang, then make duct piece assembling machine reversing frame retreat certain stroke, to obtain the operating space of armature boring machine 7; Then the armature boring 9 that uses armature boring machine 7 circumferentially to arrange by body 6 housings after radial type hard rock shield machine main frame, hole to rock stratum 1 and squeeze into anchor pole 8, and anchor pole 8 is fixed, use hinged oil cylinder to draw radial type hard rock shield machine main frame precursor 4, be with movable knife disc 3 to move by radial type hard rock shield machine main frame precursor 4, obtain the space for changing hobboing cutter 2, the cutting edge of hobboing cutter 2 and rock stratum 1 are maintained a certain distance.Manually carry out afterwards hobboing cutter 2 and change, after completing hobboing cutter 2 and more changing jobs, operating personnel remove anchor pole 8, and by bolt, shutoff cover plate 11 and sealing mat 12 are fixed on the housing of body 6 after radial type hard rock shield machine main frame, and armature boring 9 is carried out to shutoff.Just can operate afterwards radial type hard rock shield machine and continue driving.
Using the utility model to carry out hobboing cutter 2 more changes jobs, only need to utilize armature boring machine 7 to squeeze into anchor pole 8 by armature boring 9 to rock stratum 1, then utilize the equipment on existing radial type hard rock shield machine can complete whole work, can obtain quickly and easily and more renew the required replacing space of cutter, replacing cutter time, workload in native storehouse are saved, reduce in hole the tool changing risk property done strong, also avoided the damage of new cutter simultaneously, reduced business economic loss.
Above embodiment is only for illustrating preferential embodiment of the present invention; but the present invention is not limited to above-mentioned embodiment; in the ken possessing at described field those of ordinary skill; any modification of doing within the spirit and principles in the present invention, be equal to and substitute and improvement etc., within it all should be encompassed in the technical scheme scope of request protection of the present invention.
