Preferably, the swing arm includes the first arm and the second arm, first arm and second arm are with can be opposite
The mode of sliding, which is configured so that the swing arm, to stretch, so that heading equipment can have the adjusting of wider range, make
With more convenient, more construction operating conditions can be suitable for.
Preferably, the rack includes the frame in " door " font, two frame spaces are arranged and pass through cross bar
It is fixedly connected, structure is simple.
Preferably, the driving component includes drilling rod, the drilling rod is inclined outwardly on tunneling direction, slopes inwardly
Or the mode parallel with tunneling direction is arranged, drilling rod is arranged in a manner of being inclined outwardly, so that drilling rod can be in the design in tunnel
Drilling is carried out on contour line to realize the driving of tunnel tunnel contour line.
Preferably, being fixedly installed hydraulic cylinder in the swing arm, the cylinder body of first arm and the hydraulic cylinder is fixed,
The piston of second arm and the hydraulic cylinder is fixed, and the swing arm is realized flexible by the driving of the hydraulic cylinder.
Compared with prior art, the utility model has the beneficial effects that the pivot of swing arm enables driving component to adjust pick
Into angle, more multi-environment working condition can be suitable for, further, it is possible to adapt to different tunnel diameters in a certain range；
Driving component outside using cavity tunnels to form tunnel wall surface, and the middle region to form tunnel is tunneled using the driving component in cavity
Domain, while carrying out and not interfering with each other, it will be able to it improves drivage efficiency and structure is simpler.
Detailed description of the invention:
Fig. 1 is the structural schematic diagram of the application tunnel piercing device；
Fig. 2 is A in Fig. 1 to schematic diagram；
Fig. 3 is the application drilling rod arrangement schematic diagram；

Marked in the figure: 110- rack, 120- swing arm, the first arm of 121-, the second arm of 122-, the hanging end 123-, 130- pick
Into component, 131- drilling rod.
Specific embodiment
The utility model is described in further detail below with reference to test example and specific embodiment.But it should not be by this
The range for being interpreted as the above-mentioned theme of the utility model is only limitted to embodiment below, all to be realized based on the content of the present invention
Technology belongs to the scope of the utility model.
Referring to Fig. 1-4, a kind of tunnel piercing device, including rack 100, swing arm 120 and driving component 130, rack 100 are wrapped
The frame in " door " font is included, arranges before and after two frames and is simultaneously fixedly connected by cross bar, swing arm 120 is with can be pivotably
It is arranged on frame, driving component 130 is arranged on the hanging end 123 of swing arm 120.
Make rack 100 form a cavity with Fig. 4, the frame of two " door " fonts referring to fig. 2, pass through pendulum in cavity
Arm 120 arranges multiple driving components 130, passes through swing arm 120 outside cavity and arranges multiple driving components 130, multiple outside cavity
It tunnels component 130 and tunnels the wall surface that rock stratum forms tunnel, multiple driving components 130 driving in cavity is in tunnel central region
Rock stratum.Swing arm 120 can pivot in rack 100, and pivot axis is parallel with the axis in tunnel, so as to adjust driving angle
Degree, in addition, swing arm 120 includes the first arm 121 and the second arm 122, the first arm 121 and the second arm 122 are to be capable of opposite sliding
Mode, which is configured so that swing arm 120, to stretch, so that driving component 130 can be adjusted arbitrarily, make it possible to cleverer
