Specific embodiment
A kind of underground coal mine groover grooving apparatus, including underworkings fluting cutterhead 9 and mounted on fluting locomotive
Pedestal 14 on frame is hinged with large arm 1, between large arm 1 and pedestal 14 on pedestal 14 by the articulated shaft I 13 laterally set
The large arm drive cylinder 12 swung up and down equipped with driving large arm；The front end of the large arm 1 is hinged with middle arm 5 by articulated shaft II,
Articulated shaft II is arranged in parallel with articulated shaft I；It is separately installed at left and right sides of the forepart of large arm under 11,2 swing arms 11 of swing arm
End is hinged with the left and right sides of corresponding large arm, and the upper end of 2 swing arms 11 is connected by swing arm connecting shaft, and the large arm is equipped with band
The swing arm driving oil cylinder 15 of movable pendulum arm swing, piston rod outer end and the swing arm of swing arm driving oil cylinder 15 are hinged, the swing arm 11
It is equipped with and extends forwardly through pull rod axis pin 3 and the hinged pull rod 4 of middle arm 5, pull rod axis pin is arranged in parallel with articulated shaft II；It is described
The front end of middle arm is hinged with forearm 7 by articulated shaft III 10, and articulated shaft III 10 is arranged in parallel with articulated shaft II, in forearm 7 in
The forearm drive cylinder 6 that driving forearm is swung up and down, the front end that the cutterhead passes through connector 8 and forearm are equipped between arm 5
It is fixedly connected.The utility model can replace the equipment of artificial fluting operation completely so that the fluting operation of coal mine underground
It realizes mechanization, improves efficiency, reduce construction safety hidden danger, while compact-sized, there is rational intensity, it is light-weight, it is each to close
Save convenient, flexible, easy to operate convenient for control, suitable China's major part coal mine roadway space requirement.The large arm drive cylinder
For single-stage oil cylinder.The forearm drive cylinder is two-stage oil cylinder, stretches and realizes the swing of forearm.
Originally it is that the swing of utility model forearm compares middle arm, is solely dependent upon relative to the swing angle of middle arm small
The stroke of arm drive cylinder, the elongation of forearm drive cylinder, then forearm is to lower swing, conversely, forearm drive cylinder shortens, then it is small
Arm is swung up, and swing angle depends on the locating distance and stroke of oil cylinder.The swing of middle arm is relative to large arm, phase
For large arm swing angle depend on swing arm driving oil cylinder stroke, swing arm driving oil cylinder and it is indirect connect with middle arm,
But completed by swing arm, pull rod, in this way, without motion dead point, meanwhile, intensity is increased, when swing arm driving oil cylinder extends,
Middle arm is to lower swing, and when swing arm driving oil cylinder shortens, middle arm is swung up, at the same the angle of forearm and middle arm be it is constant,
I.e. forearm and middle arm can regard an Integral swinging as.The swing of large arm depends on large arm drive cylinder, and large arm drive cylinder extends,
Then large arm is swung up, and large arm drive cylinder shortens, then large arm is to lower swing, at this point, forearm, middle arm and large arm are relatively motionless,
I.e. forearm, middle arm and large arm can regard an Integral swinging as.Oil is driven by large arm drive cylinder, swing arm driving oil cylinder and forearm
It stretches, work in coordination while cylinder, you can realize the different movement locus of cutterhead, can realize that straight line is transported in hunting range
It is dynamic, movement in a curve etc..
The large arm drive cylinder is arranged on the lower section of large arm；The swing arm driving oil cylinder is arranged on greatly by hinged seat 16
The top of arm.The symmetrical left and right sides for being equipped with 2 and being separately positioned on large arm of the hinged seat 16.The pull rod is symmetrically set
There are 2, one end of 2 pull rods is hinged by pull rod axis pin and middle arm, and the other end of pull rod is connected by pull rod connecting shaft 2, institute
The piston rod outer end for stating swing arm driving oil cylinder is hinged in the pull rod connecting shaft 2 between 2 pull rods.The swing arm, pull rod, large arm
Four-bar linkage structure can be regarded as with middle arm, the swing arm driving oil cylinder above large arm is connected by hinged seat with large arm, and is put
The piston rod end of arm drive cylinder and the middle part of swing arm connecting shaft are hinged, and the pull rod is arranged with two, and 2 pull rods lead to
Same pull rod axis pin is crossed to be hinged with swing arm connecting shaft, and the piston rod end of swing arm driving oil cylinder is arranged between 2 pull rods
Pull rod connecting shaft on, in this way, can realize the swing of aligning arm and the piston rod of swing arm driving oil cylinder is positioned,
Arm in hydraulic oil cylinder driving is facilitated to swing up and down.The connector is abutted flange.The cutterhead include cutting downhole tunnel side wall,
Top plate, the cutting units of bottom plate and the tie-plate that connects with abutted flange.
