Abstract
The utility model discloses a kind of hard rock push-bench cutterhead, including cylindrical cutterhead body（4）, and the center butterfly hobboing cutter being distributed in respectively along its axis on its surface（1）With periphery butterfly hobboing cutter（2）, and periphery butterfly hobboing cutter（2）Positioned at center butterfly hobboing cutter（1）Periphery, both are with the use of can realize tunneling boring cutting function；The cutterhead body（4）Gauge knife is disposed with side（3）, hole wall cutting function can be realized.Designed by the distribution to rock cutter and mud hole, this cutterhead is applied to the firm geological conditions such as superhard rock, and practical application effect is good, drastically increases rock-breaking efficiency.
Description
Technical field
The utility model is related to a kind of topping machanism of trenchless engineering machinery, specifically a kind of hard rock push pipe machine knife
Disk.
Background technology
Push-bench belongs to a kind of trenchless engineering machinery, and cutting operation, applicable ground are carried out to the soil body by cutterhead rotation
Matter condition and range is wide, and pore-forming accuracy is good, small to ground settlement influence, with good market prospects.
Cutterhead is the main device that push-bench cuts the soil body, extensive currently for the cutterhead under the geological conditions of soil layer
Using, and the shortcomings of can then face low construction efficiency, quick abrasion, high risk to the cutterhead under hard rock geological conditions.For hard
In the jacking construction on rock stratum, particularly minor diameter, it is badly in need of the design matching used hard rock cutterhead of push-bench, improves ground consisting of hard rock
Efficiency of construction and reliability.
The content of the invention
For above-mentioned existing technical problem, the utility model provides a kind of reasonable compact conformation, reliability and construction effect
Rate is high, it is adaptable to the push-bench cutterhead under hard rock geological conditions.
To achieve the above object, the utility model provides a kind of hard rock push-bench cutterhead, including cylindrical cutterhead master
Body, and the center butterfly hobboing cutter and periphery butterfly hobboing cutter being distributed in respectively along its axis on its surface, and periphery butterfly hobboing cutter
Positioned at the periphery of center butterfly hobboing cutter, both, which use cooperatively, can realize tunneling boring cutting function；On the cutterhead body side
Gauge knife is disposed with, hole wall cutting function can be realized.
Further, described cutterhead body surface is radially distributed with mud hole, and mud hole be respectively positioned on it is adjacent outer
Between all butterfly hobboing cutters.Further, described mud hole periphery and peripheral surfacing have wear resistance electrode.So that cutterhead is applied to surpass
The firm geological conditions such as hard rock, practical application effect is good, drastically increases rock-breaking efficiency.
Further, described center, periphery butterfly hobboing cutter are to be alternately arranged.
The utility model push-bench cutterhead passes through the distribution to rock cutter and mud hole, it is adaptable to which ground consisting of hard rock is applied
Work, has the following advantages that：1st, because butterfly hobboing cutter has the function of rotary cutting so that the service life of hobboing cutter and to hard rock
Grinding efficiency is significantly improved；2nd, cutterhead body periphery uses gauge knife, is easy to the maintaining of cutterhead；3rd, mud hole week
The design of the overall surfacing wear resistance electrode in side and periphery so that the reliability of cutterhead is higher.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is Fig. 1 Structure explosion diagram；
In figure：1st, center butterfly hobboing cutter, 2, periphery butterfly hobboing cutter, 3, gauge knife, 4, cutterhead body.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, the utility model includes cylindrical cutterhead body 4, center butterfly hobboing cutter 1, periphery butterfly
Shape hobboing cutter 2, gauge knife 3.
Wherein, to be distributed in its respectively along the axis of cutterhead body 4 same for center butterfly hobboing cutter 1 and periphery butterfly hobboing cutter 2
On one surface, and periphery butterfly hobboing cutter 2 is located at the periphery of center butterfly hobboing cutter 1, and both, which use cooperatively, can realize that tunneling boring is cut
Cut function.Quantity can be adjusted as needed, and both can also be alternately arranged.
Gauge knife 3 is arranged on the side of cutterhead body 4, and quantity can be adjusted as needed, can realize hole wall cutting power
Energy.The protection to periphery butterfly hobboing cutter 2 is formed, while improving hole quality.
The surface of cutterhead body 4 is radially distributed with mud hole, and mud hole be respectively positioned on adjacent periphery butterfly hobboing cutter 2 it
Between, its periphery and peripheral surfacing have wear resistance electrode.
When the utility model cutterhead rotates, center butterfly hobboing cutter 1 and periphery butterfly hobboing cutter 2 are squeezed to the hard rock in the soil body
Press rotation broken, then gauge knife 3 cuts the hard rock of hole wall, while the hard rock particle under broken passes through the surface of cutterhead body 4
Mud hole enters inside mud water balance push bench.So that this cutterhead is applied to the firm geological conditions, practical application such as superhard rock
Effect is good, drastically increases rock-breaking efficiency.
