A kind of laser assisted broken rock equipment, including driving device, cutter head, cleaning plant and laser system, laser system
System includes that an at least laser generator exports optical head at least one laser being mutually connected therewith；It neutralizes laser generator
It is mounted on the cutter head according to preset position with laser output optical head, driving device pushes heading equipment simultaneously
The cutter head is driven, during driving, the laser beam that laser generator is sent out exports optical head by pre- by laser
Positioning, which is set, to be radiated on driving surface, and the rock or other objects tunneled on surface is heated in the case where absorbing laser energy, structure
Occur to weaken and destroy under the action of the cutter head is fixed a cutting tool, so that driving is completed, cleaning plant is then in driving
Cleaning rubble disintegrating slag simultaneously ensures that driving can be carried out continuously.Here cutter can be hobboing cutter or other cutters.
In this heading equipment, it in addition may include laser cooler and power-supply system, be used for each laser generator
Power supply and offer cooling.
The power of every laser generator can be selected arbitrarily, for example can arbitrarily be selected between 50-20000W.Laser work(
Rate can be adjusted arbitrarily.When multiple path laser in use, each road laser output power can be adjusted to the same or different on demand.
In addition the light spot shape being radiated on development end rock or other objects can be set as round as required, rectangular,
Rectangle or irregular shape.
The laser generator can be required with light beam and cost performance arbitrarily selects.For example the laser generator can be
Semiconductor laser, optical fiber laser or other solid state lasers.The operating mode of laser can be continuous output, can also be
Pulse exports.Operation wavelength can also be selected arbitrarily, but wavelength is that the laser cost performance of near-infrared is relatively high at present.
Can also include device for monitoring temperature in heading equipment to best achieve the purpose that auxiliary rock, it is such as red
Outer monitoring temperature or other monitoring systems are used for monitoring the temperature of heating part, it might even be possible to defeated by temperature feedback control laser
Go out to reach optimum efficiency.
When needed, the laser export head in the present invention can be added beam-splitting structure and realize multiple-channel output.On the generator
Can also meet the needs of multiple-channel output by mostly respectively exporting optical head.
For the relationship for meeting laser irradiation angle and cutterhead is fixed a cutting tool, cutterhead, which is equipped with, corresponds to laser output optics
There is head optical window, the position that the optical window is connected on cutterhead to have scheduled angle, make laser from output light
Cutter site of action rock surface nearby can be irradiated in predetermined angular by learning after head projects.Hot spot is irradiated with cutter (as rolled
Knife) relative position can ensure driving peak efficiency.Rock near hobboing cutter operating position weakened under laser heating or
The broken rock effect that softening maximum can play cutter (such as hobboing cutter).Laser facula is kept near cutter site of action i.e. in driving
Rock surface is in the state of softening or reduction, and the rock of site of action loses lateral support, and is ruptured under cutter effect.
It is characteristic of the invention that：
The laser that laser generator generates exports optical head by the laser and is directly output to development end, and laser is from knife
Corresponding laser hole projects on disk, forms laser heating zone in driving surface institute irradiation area, weakens the property of machined surface, and
In cutter, such as hobboing cutter, synergistic effect under reach driving purpose.For existing rock tunnel(ling) machine, the present invention, which utilizes, to be swashed
The mode of light auxiliary rock can reduce formation hardness, greatly improve constructing tunnel efficiency and construction quality, cutter, such as hobboing cutter,
Without often replacing, manpower is saved, construction cost and difficulty of construction, but also the safety of the construction improved are not only reduced
Property.
