Description
Technical field
The present invention relates to tunnel hard rock mole (TBM), more particularly, to the TBM cutterhead for carrying carbide chip.
Background technique
Now across basin, it is trans-regional draw, in water diversion project, (the western line Tunnel length in such as China is more than for long tunnel
It is often 200km) that the first choice of engineering draws (defeated) water buildings, under conditions of landform, geological conditions limitation, is applied to improve tunnel
Work speed, shortens the duration of a project, and preferred arrangement and method for construction mostly uses TBM to construct.Traditional TBM cutterhead is as shown in figure 5, by cutterhead
1.1, the multiple disk cutters 2.1 being arranged on 1.1 working face of cutterhead, and be evenly arranged on 1.1 work surface edges of cutterhead
Four scraper bowls 3.1 form.Thrust that power cylinder provides only is promoted mainly by 2.1 injection rock of disk cutter, disk by TBM when headwork
Shape hobboing cutter 2.1 is passively rolled and is cut with the movement of cutterhead 1.1, squeezed, fractured rock, to realize that tunnel drivage is opened
It digs.It is counted according to existing engineering data, the conventional average drill footage per month of TBM construction is 500m~1000m, this allows for long tunnel construction
Duration is generally up to the several years to more than ten years, seriously restricts the duration of engineering.
Summary of the invention
It is an object of that present invention to provide a kind of TBM cutterheads for carrying carbide chip, are cut by carbide chip
Rock and disk cutter pressure injection combined-breaking rock reach the purpose for quickly carrying out tunnel drivage excavation.
To achieve the above object, the present invention takes following technical proposals:
The TBM cutterhead of the present invention for carrying carbide chip, including TBM cutterhead body, the TBM cutterhead body is by installing
On cutterhead fixed frame cutterhead, be arranged on the cutterhead working face multiple disk cutters, be evenly arranged on cutterhead working face side
Four scraper bowls composition on edge；The running track line of multiple disk cutters is annular；It is provided on cutterhead working face multiple
The carbide chip being driven by motor, multiple carbide chips close to disk cutter running track line arrange, often
A carbide chip is each perpendicular to cutterhead working face；The cutterhead back side is provided with the confession for being electrically connected with TBM main control room
Electric swivel joint, the power supply swivel joint are located at the centre of gyration of cutterhead；The driving motor of each carbide chip is logical
Cable is crossed to connect with power supply swivel joint.
The carbide chip is arranged in the direction of advance of the disk cutter operation.
The present invention, will using being cut in industrial production using carbide chip, carving the mature technologies such as metal or rock
Carbide chip is installed to TBM cutterhead, carries out joint-cutting to face using carbide chip, then with disk cutter pressure
Injection rock considerably increases the efficiency of breaking rock of disk cutter radially, reaches carbide chip cutting rock and dish type is rolled
Knife pressure injection combined-breaking rock, improves TBM efficiency of breaking rock.Simultaneously as carbide chip cuts the joint-cutting to be formed, one
Determine to also reduce the tool wear of disk cutter in degree, extend the service life of disk cutter, saves the fortune of TBM equipment
Row maintenance expense and construction investment improve TBM tunneling construction efficiency on the whole, reduce TBM equipment energy consumption.

Specific embodiment
As shown in Figs 1-4, the TBM cutterhead of the present invention for carrying carbide chip, including TBM cutterhead body, it is described
TBM cutterhead body by the cutterhead 2 being mounted on cutterhead fixed frame 1, the multiple disk cutters 3 being arranged on 2 working face of cutterhead,
Four scraper bowls 4 composition of the cloth on 2 work surface edges of cutterhead；The running track line 5 of multiple disk cutters 3 is annular；2 work of cutterhead
Make to be provided with multiple carbide chips 7 driven by motor 6 on face, fortune of multiple carbide chips 7 close to disk cutter 3
The direction of advance that disk cutter 3 is run is arranged and be located to row trajectory line 5, and the diameter of each carbide chip 7 is each perpendicular to knife
2 working face of disk；The back side on cutterhead fixed frame 1 positioned at cutterhead 2 is provided with the power supply for being electrically connected with TBM main control room and returns
Adapter 8, power supply swivel joint 8 are located at the centre of gyration of cutterhead 2；The driving motor 6 of each carbide chip 7 passes through electricity
Cable 9 and power supply swivel joint 8 are electrically connected, power supply swivel joint 8 by power in power supply line 10 and TBM main control room and
Control system electrical connection.
Fig. 4 gives the structural schematic diagram of the carbide chip 7 driven by motor 6, and carbide chip 7 uses wolfram steel
Material.According to current industrial processing technology application analysis both at home and abroad, the structure size of carbide chip 7 of the present invention according to
Country rock situation, outer diameter are chosen within the scope of 100cm ~ 300cm, and wall thickness is chosen within the scope of 3mm ~ 50mm, carbide chip 7
Revolving speed is not less than 600 revs/min, then determines after experimental study.
Working principle of the present invention is summarized as follows:
The thrust that traditional TBM is provided only with featured power cylinder by disk cutter injection rock, disk cutter with cutterhead fortune
It moves and passively rolls and cut, squeezes, fractured rock, to realize that tunnel drivage is excavated.
The present invention is that carbide chip 7 appropriate is arranged on traditional TBM cutterhead, and carbide chip 7 is located at dish type
Near 3 motion profile line 5 of hobboing cutter.The driving motor 6 for starting carbide chip 7 while starting cutterhead 2 and rotating, passes through
The high speed rotation of carbide chip 7 cuts rock, carries out joint-cutting to face rock.With the rotation of cutterhead 2, disk cutter
3 indentations cut, squeeze, fractured rock by the face rock of joint-cutting, thus realize that tunnel drivage is excavated, it will be traditional
The compound injection of " pre- joint-cutting+pressure " is changed into TBM simple pressure injection, is reduced 3 injection thrust of disk cutter, is reduced
The abrasion of disk cutter 3.
