Description
Technical field
The present invention relates to a kind of shield thermomechanical components, more particularly, to a kind of cutter and band being used under the conditions of height wears geology
There is the shield cutter of cutter.
Background technology
Shield excavation machine is a kind of special engineering machinery of tunnel piercing, and its advantage is adapted for big depth, long range, various
The pipeline constructing tunnel of diameter.Cutter head of shield machine and cutter are the cores that shield machine smoothly tunnels.
In the past in the high abrasion geological conditions of the cutters such as sandstone, sandy gravel, often through increase cutter changing frequency or add
Big tool dimension solves high wear problem.Increase cutter changing frequency consumes substantial amounts of manpower and materials, and influences the construction period；
Tool dimension is increased due to the limitation of cutterhead pattern and motor power, size adjusting can only be carried out in certain scope.
The content of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of simple in construction, intensity
Greatly, the cutter being used under the conditions of high abrasion geology of high abrasion and the shield cutter with cutter.
The purpose of the present invention can be achieved through the following technical solutions：
It is cylindrical structural for the high cutter worn under the conditions of geology, including pedestal, matrix and is connected on matrix
Cutter hub, described matrix are provided with fluting, and described cutter hub is connected in groove, and each cutter hub forms cylindrical-shaped structure.
Described cutter hub includes crescent cutter hub and strip cutter hub, and described crescent cutter hub is connected to body upper surface
Both sides, described strip cutter hub is connected to the centre position of body upper surface.
Described crescent cutter hub uses silver-based solder, is welded on using the pasty state mixed solvent for being dehydrated boric acid and potassium fluoride
On the matrix of described fluting.
The crescent cutter hub for being connected to both sides is symmetrically arranged.
Described strip cutter hub uses silver-based solder, is welded on using the pasty state mixed solvent for being dehydrated boric acid and potassium fluoride
On the matrix of described fluting.
Two strip cutter hubs being connected between symmetrically are arranged.
Described matrix is welded to connect on pedestal.
Described matrix is cylindrical structural.
The cutter is welded to connect on cutterhead by pedestal, can be according to geological conditions flexible distributed on shield cutter.
Cylindrical cutting tool of the present invention, its architectural characteristic are that radial and axial bearing capacity is balanced, improve the stabilization of cutter
Property, meet the complicated working environment of shield machine.It uses crescent knife, improves the casting efficiency of cutter；Strip knife improves
Knife ambilateral wearability.
Compared with prior art, the present invention is applied in engineering practice, improves the digging efficiency of cutterhead, adds shield
Machine knife disk single promotes mileage, and identical promotes mileage not have to tool changing；In its progradation, driving torque and fltting speed and original
Cutters layout is suitable.
Brief description of the drawings
Fig. 1 is the main structure diagram of the present invention；
Fig. 2 is the overlooking the structure diagram of the present invention；
Fig. 3 is the structural representation of shield cutter.
In figure, the left crescent cutter hub of 1- shield cutters, 2- cutters, 3-, the right crescent cutter hubs of 4-, the left strip cutter hubs of 5-,
The right strip cutter hubs of 6-, 7- matrixes, 8- pedestals.
Embodiment
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment
A kind of cutter 2 for shield machine, its structure can make as shown in Fig. 1~2 under the geological conditions of height abrasion
With, it is cylindrical structural, including pedestal 8, matrix 7 and the cutter hub being connected on matrix 7.Matrix 7 is cylindrical structural, in matrix
7 are provided with fluting, and cutter hub is connected in groove, and each cutter hub forms cylindrical-shaped structure.
In the present embodiment, the cutter hub used for crescent cutter hub and strip cutter hub, left crescent cutter hub 3 and with right crescent moon
Shape cutter hub 4, using silver-based solder, the pasty state mixed solvent of dehydration boric acid and potassium fluoride is welded on the both sides of the upper surface of matrix 7, and
And it is symmetric.Left strip cutter hub 5 and right strip cutter hub 6 use silver-based solder, are dehydrated the pasty state of boric acid and potassium fluoride
Mixed solvent is welded on the centre position of the upper surface of matrix 7, and is symmetric.The structure of shield cutter 1 with cutter 2
As shown in figure 3, cutter 2 is welded to connect on shield cutter 1 by pedestal 8, can be according to geological conditions flexible distributed in shield
On cutterhead 1.The cylindrical cutting tool of use, its architectural characteristic are that radial and axial bearing capacity is balanced, improve the stabilization of cutter
Property, meet the complicated working environment of shield machine.It uses crescent knife, improves the casting efficiency of cutter；Strip knife improves
Knife ambilateral wearability
The present invention is applied in No. 14 line engineering constructions of Beijing Metro, its excellent working performance, with former cutter and arrangement phase
Than identical promotes mileage not have to tool changing；In its progradation, driving torque and fltting speed are suitable with former cutters layout.
