Please refer to Fig. 4 to Fig. 6, the master of first installing rack of the protection system that Fig. 4 is provided for a kind of specific embodiment of the present invention looks schematic diagram; The schematic top plan view of first installing rack of the protection system that Fig. 5 is provided for a kind of specific embodiment of the present invention; The schematic side view of first installing rack of the protection system that Fig. 6 is provided for a kind of specific embodiment of the present invention.
Particularly, sender unit 2 can be installed on coal-winning machine 12 by first installing rack 7, and is positioned at a side relative with the cylinder 121 of coal-winning machine 12.Like this, sender unit 2 is along with the motion of coal-winning machine 12 is moved together, the extended position of first signal of sender unit 2 emissions constantly changes, and when signal receiving device 3 receives first signal, just shows that coal-winning machine 12 and hydraulic support 11 arrive danger position.Simultaneously, sender unit 2 is installed on a side relative with the cylinder 121 of coal-winning machine 12 and can prevents that coal from damaging sender unit 2.
The installation of sender unit 2 for convenience, first installing rack 7 can comprise by the riser 71 of bolt in coal-winning machine 12, with the transverse slat 72 vertical with its cardinal principle, sender unit 2 by bolt in transverse slat 72, all offer circular hole 711 and strip hole 712 on riser 71 and the transverse slat 72, bolt passes circular hole 711 and strip hole 712.Like this, bolt can be realized the adjusting of first installing rack 7 at the angle α of vertical direction and coal-winning machine 12 by the diverse location that connects strip hole 712, and the adjusting of sender unit 2 and first installing rack 7 angle β in the horizontal direction, thereby on both direction, change the transmit direction of first signal, thereby adjust predetermined relative location.Angle α and angle β can be 10 degree particularly.
Particularly, transverse slat 72 is positioned at the top of sender unit 2.Top as herein described is the top of position shown in Figure 6.
Like this, transverse slat 72 can prevent that coal from being fallen by the top, damages sender unit 2, has protected sender unit 2, has prolonged the application life of sender unit.Certainly, block the propagation of first signal, the first signal transmitting terminal of sender unit 2 can be arranged at the outside of transverse slat 72 in order to prevent transverse slat 72.
In a kind of specific embodiment, signal reflex device 6 can be installed on the back timber 111 of hydraulic support 11 by second installing rack 8.Like this, receive first signal, and when it was reflexed to signal receiving device 3, control device 5 control coal-winning machines 12 were shut down when sender unit 2 moves to signal reflex device 6 with coal-winning machine 12.
Particularly, signal reflex device 6 can be reflecting plate 9.Reflecting plate 9 simple in structure, cost is lower, and the usable reflection angle is bigger, has reflecting effect preferably.
Please refer to Fig. 7 and Fig. 8, the schematic side view of second installing rack of the protection system that Fig. 7 is provided for a kind of specific embodiment of the present invention; The master of second installing rack of the protection system that Fig. 8 is provided for a kind of specific embodiment of the present invention looks schematic diagram.
As shown in Figure 8, second installing rack 8 comprises that first hang plate 81 that connects by junction plate 83 and second hang plate, 82, the first hang plates 81 and second hang plate 82 are substantially about the middle vertical plane symmetry of junction plate 83; The number of reflecting plate 9 is two, is installed on the outside of first hang plate 81 and second hang plate 82 respectively.The reflecting plate 9 in first hang plate 81 and second hang plate, 82 outsides can reflect first signal of both direction, thereby makes it be applicable to the production practice of two-way coal cutting, has enlarged the scope of application.
Particularly, sender unit 2 and signal receiving device 3 can have integrative-structure, form the signal sending and receiving apparatus, thereby have reduced the number of device, have reduced cost.
On the other hand, because that laser signal has is directed luminous, light luminance height, the pure characteristics of color, therefore, first signal can be laser signal, correspondingly, sender unit is a generating laser, and the signal sending and receiving apparatus can be specially the Laser emission receiver.Just with laser as first signal, transmit, improved the accuracy that signal transmits, thereby improved the reliability of protection system the hydraulic support protection, guaranteed the safety of comprehensive mechanical coal mining complete equipment coal mining process.
Except above-mentioned protection system, the present invention also provides a kind of comprehensive mechanical coal mining complete equipment that comprises above-mentioned protection system.
More than comprehensive mechanical coal mining complete equipment provided by the present invention and protection system thereof are described in detail.Used specific case herein principle of the present invention and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present invention and core concept thereof.Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention, can also carry out some improvement and modification to the present invention, these improvement and modification also fall in the protection domain of claim of the present invention.
