Description
Technical field
The present invention relates to rock tunnel(ling) machine fields.
Background technology
Rock tunnel(ling) machine is worked continuously with Mechanical Crushing rock, muck removal and supporting implementation, is mechanical, electrical, liquid, light, gas etc.
The batch production assembly line constructing tunnel equipment of the system integration, the equipment by anterior shield, branch pole, flexible shield, only row shield, cutterhead, after
Mating composition.By working angles of the development machine on working face, it is divided into full face tunnel boring machine and partial-size tunneling machine.By broken
Rock principle is different, and can divide rolling-type（Disk cutter）Development machine and milling formula development machine.Chinese products are mostly that rolling-type is complete
Section boring machine, suitable for middle hard rock to hard rock.Development machine is under the axial compressive force effect of propelling cylinder during work, motor drive
Hobboing cutter cutterhead rotate, rock is hobbed it is broken, around have bucket, be discharged on conveyer belt with rotation.Rock tunnel(ling) machine is being dug
It generates heat into hobboing cutter in the process and rock frictional test, temperature aggravates hob abrasion, the lost of life, about 300- up to more than 300 degree
500 meters need to change, and make the ratio that the cost of charp tool accounts for totle drilling cost higher.Cutterhead bears high-strength impact load in tunneling process
Lotus, vibration is very violent, and key member premature harm is caused to fail, and base bearing damage, mechanical life shortens, and rock fracture is also tight
Driving speed and speed of application are affected again, it was reported that are tunneled in its highest moon of China once up to 1209.8 meters, efficiency is not very
It is high.
Its principle of High Pressure Water Jet Cutting Technology is that water pressurizes in force (forcing) pump, by high-voltage tube, then from cutting nozzle
It shoots out, so as to generate high-pressure water jet.At the end of the 20th century, Water Cutting technology introduces China, the early 21st century, portable Water Cutting
Technology occurs.Portable Water Cutting technology category low pressure water-jet technology, that is, utilize lower pressure（25 Mpa-50Mpa）It can be real
The cutting operation of cash category and other materials.Its with small, cut coverage is wide, cutting when empty calory generate, cutting speed
The characteristics of fast and efficient, can cut steel plate, ceramics, marble, cement products etc., but it does not have in cutting process
It is standby to roll crushing function.
Invention content
Technical problem solved by the invention is：How High Pressure Water Jet Cutting Technology to be made to be combined with rolling-type so that
It is provided simultaneously with the advantage of the two.
The technical solution adopted in the present invention is：Water jet cuts rock tunnel(ling) machine, cutterhead（1）On have the first hobboing cutter（5）、
With the first hobboing cutter（5）Vertically arranged second hobboing cutter（4）, be arranged in the first hobboing cutter（5）With the second hobboing cutter（4）The third rolling in outside
Knife（3）, third hobboing cutter（3）There are more, third hobboing cutter adjacent to each other（3）The cutterhead in center（1）On be disposed with high-pressure water outlet
（2）, high-pressure water outlet（2）Connection connects high-pressure pump by high-pressure water pipe.
As a kind of preferred embodiment：Third hobboing cutter adjacent to each other（3）The cutterhead in center（1）On be disposed with 2-5 high pressure
Water out（2）.
As a kind of preferred embodiment：High-pressure water outlet（2）Direction and cutterhead（1）Into 30 degree of angles and it is biased to cutterhead（1）
Axis direction.
The beneficial effects of the invention are as follows：The present invention overcome existing tunnel development machine driving speed is slow, efficiency is low, it is of high cost,
The shortcomings of long in time limit.Several high-pressure water outlets are set in this programme on development machine cutterhead（Cut nozzle）, high-pressure water outlet（It cuts
Cut nozzle）In 30 degree angles and the axis direction of cutterhead is biased to cutterhead face, mating portions set force (forcing) pump after development machine, logical
High-voltage tube connection force (forcing) pump and cutting nozzle are crossed, forms high pressure water flow during machine operation at nozzle, cuts rock.It is broken with single
Lithofacies ratio can artificially change rock fracture by high -pressure water cutting, and cut nozzle with cutterhead face in 30 degree of angles when it is generated
Rock fracture, in hobboing cutter fractured rock under the conditions of this crack, rock has minimum leap point lotus number, anti-invasion coefficient, intrusion
Work(and lead crack extension energy, rock are easy to crush, and significantly improve the driving speed of development machine, while reduce cutterhead shake
It is dynamic, extend the base bearing service life, and in cutting process, remain in rock and hobboing cutter can be dropped with the water on cutterhead contact surface
Temperature extends cutter life.This programme can significantly accelerate speed of application, shorten the construction period, the prolonged mechanical service life, reduce construction assembly
This.

Specific embodiment
As shown in Figure 1-Figure 3, the present invention is the improvement on the basis of existing rolling-type rock tunnel(ling) machine, existing rolling
The first hobboing cutter, the second hobboing cutter, third hobboing cutter, the first hobboing cutter, the second hobboing cutter, third rolling are provided on the cutterhead of formula rock tunnel(ling) machine
Knife tunnels rock rolling-type using coaxial grinding wheel.Due to rock tunnel(ling) machine in tunneling process hobboing cutter and rock frictional test generate heat and
Cutterhead bears high-strength impact load in tunneling process leads to hobboing cutter（First hobboing cutter, the second hobboing cutter, third hobboing cutter）Easily damage
Bad, hobboing cutter axis is easily damaged, and drastically influences driving speed and speed of application, the present invention is in order to overcome problem above, in third
High-pressure water outlet is provided between hobboing cutter, high-pressure water outlet connection connects high-pressure pump by high-pressure water pipe so that rubs that can reduce
The heat generated is wiped, and causes high-pressure water outlet direction with cutterhead into 30 degree of angles and is biased to the axis direction of cutterhead, i.e.,
The face that the radius of high-pressure water outlet direction and the cutterhead where high-pressure water outlet forms in figure 3 is perpendicular to cutterhead face（∠ b are equal to
90 degree）, high-pressure water outlet direction cutterhead is into 30 degree of angles（∠ a are equal to 30 degree）.So that 30 degree of horn stone stony fractures are generated on rock
Slot gap, in hobboing cutter fractured rock under the conditions of this crack, rock has minimum leap point lotus number, anti-invasion coefficient, intrusion work(
And lead crack extension energy, rock are easy to crush, and significantly improve the driving speed of development machine, while reduce cutterhead vibrations,
Extend the base bearing service life, and in cutting process, remain in rock and can cool down with the water on cutterhead contact surface to hobboing cutter, prolong
Long cutter life.
