Detailed description of the invention
Illustrate below in conjunction with accompanying drawing and illustrate the utility model with embodiment.
There is an open type TBM for section of jurisdiction installation function, as shown in Figure 1, comprise cutterhead 1, main driving 2 and shield 3.Cutterhead 1 is a broken laccolite body, is positioned at TBM foremost, for breaking surrounding rock.Cutterhead 1 is fixed on shield 3 foremost, and cutterhead 1 rear end is fixedly connected with main driving 2, is fixed on shield 3 in the middle part of main driving 2.Main driving 2 can be with movable knife disc 1 to rotate, and the clockwise or counterclockwise speed change of cutterhead 1 is rotated, thus braking cutterhead 1.
Shield 3 is provided with girder 5, and girder 5 front end is fixed on the middle part of shield 3.The cross-sectional area of girder 5 is rectangle, as shown in Figure 2.The sidewall of girder 5 is fixed with duct piece assembling machine 4 and propelling cylinder 6, namely the cylinder body of propelling cylinder 6 is hinged on the sidewall of girder 5.
Support boots 7 are slidably arranged on girder 5 by saddletree 14.Saddletree 14 top is provided with sliding tray, and girder 5 lower end is arranged in sliding tray, thus support boots 7 are slided with girder 5 phase.Piston rod and the saddletree 14 of propelling cylinder 6 other end are hinged.Saddletree 14 two ends are respectively equipped with support boots oil cylinder 11, and support boots oil cylinder 11 can stretch left and right.Support boots oil cylinder 11 external part is connected with support boots 7, and support boots 7 are provided with groove, this groove and matching on section of jurisdiction, avoids supportting boots 7 and acts directly on section of jurisdiction, thus reaches the section of jurisdiction after to installation in tunnel and protect.This groove is the H profile steel of grille-like.
On whole girder 5, regulate the flexible saddletree 14 that can make of propelling cylinder 6 to move forward and backward, thus drive whole support boots 7 to move forward and backward.Simultaneously, the stiction of support boots 7 and section of jurisdiction on tunnel is utilized to provide the counter-force of tunneling forward for whole TBM, piston rod due to propelling cylinder 6 rear end is hinged on saddletree 14, the cylinder body of front end is hinged on girder 5, propelling cylinder 6 stretches out and can promote girder 5 and travel forward, thus whole TBM is tunneled forward.
Duct piece assembling machine 4 is become with assembled head group by assembling machine crossbeam, bracing frame, swivel mount.Assembling machine crossbeam flange is connected on girder 5, the bracing frame of assembling machine is placed in the walking trough on assembling machine crossbeam by each two rollers in left and right, inner ring is that the ball bearing outer ring of gear ring form is connected with assembling machine bracing frame by flange, inner ring is connected with swivel mount by flange, and assembled head is connected with a crossbeam with two telescopic oil cylinders with between runing rest.Duct piece assembling machine 4 can realize multivariant picking up, make section of jurisdiction can in tunnel left and right or tilt forward and back the actions such as rotation, upwards jack-up, thus can realize the left and right in tunnel and carry out section of jurisdiction installation up and down.Duct piece assembling machine 4 rear end is provided with sliding rail 12, and sliding rail 12 is arranged on the below of girder 5.Sliding rail 12 is provided with loop wheel machine 13, and loop wheel machine 13 lower end can lift section of jurisdiction.Duct piece assembling machine 4 is transported to by sliding rail 12 after needing the section of jurisdiction of installing can be sling from whole TBM rear by loop wheel machine 13.
The below of girder 5 rear end is provided with tail support system 8, and tail support system 8 props girder 5 in rear end, thus the upper end making whole girder 5 is basic horizontal, is conducive to support boots 7 and moves horizontally on girder 5.Tail support system 8 comprises bracing frame, is provided with and vertically adjusts oil cylinder in bracing frame, moves up and down for adjusting whole tail support system 8.Support system 8 lower end is provided with groove, and the projection on itself and section of jurisdiction matches.
Cutterhead 1 is provided with sand scraper and drift sand groove, and the rock block in front is delivered to conveyor 9 by sand scraper and drift sand groove, and conveyor 9 extends to whole TBM rear end through girder 5, and detritus stone is wherein transported to the rear end of TBM by conveyor 9.
The course of work: during driving, main driving 2 provides rotary motive power for cutterhead 1, is with movable knife disc 1 to rotate; On section of jurisdiction about regulating support boots oil cylinder 11 to make the support boots 7 of the left and right sides be supported on tunnel respectively, the groove of tail support system 8 lower end with in tunnel in section of jurisdiction has been installed projection match thus prop the rear end of girder 5; Propelling cylinder 6 stretches out, and promotes girder 5 and is pushed ahead by whole TBM, thus propulsive force be delivered on cutterhead 1; Cutterhead 1, under the effect of rotatory force and motive force, completes the excavation in tunnel.
When tunnel surrounding is broken, for preventing landslide, supporting must be carried out, therefore section of jurisdiction is needed to install, its process is specially: on the section of jurisdiction about regulating support boots oil cylinder 11 to make the support boots 7 of the left and right sides be supported on tunnel respectively, the groove of tail support system 8 lower end matches with the projection of having installed section of jurisdiction in tunnel thus props the rear end of girder 5; Section of jurisdiction is transported to duct piece assembling machine 4 place through sliding rail 12 by loop wheel machine 13; Duct piece assembling machine 4 by the left and right being arranged on tunnel tightly, section of jurisdiction and up and down, install by the section of jurisdiction completing this region; Support boots oil cylinder 11 shrinks to be packed up support boots 7, and propelling cylinder 6 shrinks, thus is moved forward by support boots 7, carries out the installation in next region.Namely in Bracing Process, just complete section of jurisdiction install, in real work, its driving and Bracing Process cooperatively interact thus complete excavation and the section of jurisdiction installation in whole tunnel.
The utility model utilizes duct piece installation machine 4 prefabricated pipe section to be spliced into a complete ring, and section of jurisdiction tightly props up tunnel crag, prevents country rock from shrinking in tunnel.Because tunnel rubble betides top, section of jurisdiction, top adopts close encapsulation structure, prevents chip from dropping; Sidepiece and section of jurisdiction, bottom adopt shape steel bracket structure, effectively utilize support material.
The above; be only the utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
