Embodiment
A kind of underground coal mine groover grooving apparatus, including underworkings fluting is with cutterhead 9 and installed in fluting locomotive
Base 14 on frame, large arm 1 is hinged with by the jointed shaft I 13 laterally set on base 14, between large arm 1 and base 14
The large arm drive cylinder 12 swung up and down provided with driving large arm；The front end of the large arm 1 is hinged with middle arm 5 by jointed shaft II,
Jointed shaft II be arranged in parallel with jointed shaft I；It is separately installed with left and right sides of the front portion 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 provided 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 provided with and extends forwardly through the pull bar 4 that pull bar bearing pin 3 is hinged with middle arm 5, pull bar bearing pin be arranged in parallel with jointed shaft II；It is described
The front end of middle arm is hinged with forearm 7 by jointed shaft III 10, and jointed shaft III 10 be arranged in parallel with jointed shaft II, in forearm 7 with
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 provided between arm 5
It is fixedly connected.The present invention can replace the equipment of artificial fluting operation completely so that the fluting operation of coal mine underground is realized
Mechanization, efficiency is improved, reduce construction safety hidden danger, at the same it is compact-sized, there is rational intensity, in light weight, each joint side
Just flexibly, it is easy to control, it is simple to operate, it is adapted to China's major part coal mine roadway space requirement.The large arm drive cylinder is single
Level oil cylinder.The forearm drive cylinder is two-stage oil cylinder, its flexible swing for realizing forearm.
Originally it is that the swing of invention forearm compares middle arm, it is solely dependent upon forearm relative to the swing angle of middle arm and driven
The stroke of dynamic oil cylinder, the elongation of forearm drive cylinder, then forearm is to lower swing, conversely, forearm drive cylinder shortens, then forearm to
Upper swing, its swing angle depend on the locating distance and stroke of oil cylinder.The swing of middle arm be relative to large arm, its relative to
The swing angle of large arm depend on swing arm driving oil cylinder stroke, swing arm driving oil cylinder and it is indirect be connected with middle arm, but
Completed by swing arm, pull bar, so, without motion dead point, meanwhile, intensity is added, when swing arm driving oil cylinder extends, middle arm
To lower swing, 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., it is small
Arm 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 greatly
Arm is swung up, and large arm drive cylinder shortens, then large arm is to lower swing, and now, forearm, middle arm and large arm are relatively motionless, i.e., small
Arm, middle arm and large arm can regard an Integral swinging as.Pass through large arm drive cylinder, swing arm driving oil cylinder and forearm drive cylinder
Simultaneous retractable, work in coordination, you can realize the different movement locus of cutterhead, linear motion, arc can be realized in hunting range
Line motion 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 provided with 2 and being separately positioned on large arm of the hinged seat 16.The pull bar is symmetrically set
There are 2, one end of 2 pull bars is hinged by pull bar bearing pin and middle arm, and the other end of pull bar is connected by pull bar connecting shaft 2, institute
The piston rod outer end for stating swing arm driving oil cylinder is hinged in the pull bar connecting shaft 2 between 2 pull bars.The swing arm, pull bar, 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 bar is arranged with two, and 2 pull bars lead to
Same pull bar bearing 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 bars
Pull bar connecting shaft 2 on, so, the swing of aligning arm can be realized, and can positions to the piston rod of swing arm driving oil cylinder,
Arm in hydraulic oil cylinder driving is facilitated to swing up and down.The connector is abutted flange.The cutterhead include cut downhole tunnel side wall,
Top plate, the cutting units of bottom plate and the tie-plate that connects with abutted flange.
